How to jailbreak and hacktivate iOS 4.2.1 using Redsn0w 0.9.6b6&SAM

In Apple device on 07/12/2010 at 10:23 AM

As promised from the Dev-Team, Redsn0w 0.9.6b4 for both Mac and Windows had been released quickly for our “zombreaker” 🙂 According to Dev-Team blog, they successfully handled “7700 comments over just the first 12 hours (10 per minute for half a day)” Damn ! Wish my blog was like that 🙂 Another good news is from developer @sbingner, “His tool, “Subscriber Artificial Module (SAM)” tricks your iPhone and iTunes into creating legitimate activation tickets even though you’re unlocked with ultrasn0w.  This means you get the full benefit of push applications, and your battery life increases substantially” Self-explanation, eh ? In short SAM will help your iOS look like this:

And now some WARNING signs before moving on:

  • Unlocker should restrain from upgrading to 4.2.1
  • Again, new iDevices will be jailbreak as semi-tethered (required redsn0w every time your devices reboot)

I recommend you should visit Dev-Team blog, SAM website to fully understand the procedure !

What i need ?

  • Your (fully charged) iDevices with computer and iTunes 10.1
  • RedSn0w 0.9.6b6 for Windows or Mac. Or you can visit Dev-Team blog to find the links 😉
  • Your iOS 4.2.1 respective firmware from Felixbruns or you can update/restore straight from iTunes 10.1

Guide: (Source from Redmond Pie and SAM)

  • Jailbreak using RedSn0w 0.9.6b6 basically the same as 0.6.6b4. Please visit my old post:”Jailbreak iPad, iPod and iPhone 4.2.1 with Redsn0w 0.9.6b4″ to successfully jailbreak your iDevices.
  • I need to remind you that every time your iDevice reboot or stuck at Apple logo (4.2.1 jailbreak), please repeat step 8 to 10 from my guide to be able to run your iPhone/iPad/iPod touch.
  • Once your iPhone boot up, run Cydia and add new repohttp://repo.bingner.com”
  • Wait for the reloading and install “SAM” and “SAMPrefs”
  • Run RedSn0w again, select “Deactivate”, next…
  • Navigate to Settings > SAM and click “De-Activate iPhone”
  • Start iTunes, connect your iPhone, wait for  the activation.

Note: If iTunes says invalid SIM, you will need to manually select the appropriate carrier under one of the methods besides “Automatic” and click on a SIMID.

You are done ! Want to unlock your iPhone 3G and old 3GS module ? Follow this post

Unlock for iPhone 3G/3Gs in iOS 4.2.1 (Mac version) have arrived !

In Apple device on 29/11/2010 at 2:48 AM

Thanks to Dev-Team, iPhone 3G and 3Gs can now safely upgrade to 4.2.1 along with unlock 🙂 Here are the whole article i copied from Dev-Team blog. You can find my summary and how to below and in separate new posts followed up.

Today we’re pleased to announce our free carrier unlock for iPhone3G/3GS owners with a baseband later than 05.13.04.  The unlock for that baseband exploited the AT+XAPP command, thanks to a crash initially discovered by @sherif_hashim (@Oranav also found this crash).  So what hole are we exploiting today, since Apple closed that AT+XAPP hole?  Well, we’re exploiting the exact same hole!

It turns out that the very first iPad firmware 3.2.2 has baseband version 06.15.00 still vulnerable to AT+XAPP. The iPad baseband is built for the exact same baseband chip as the iPhone3G/3GS — they’re fully compatible! Some of us have been running 06.15 for weeks now on our iPhones in preparation for this release.

SIMPLIFIED VERSION:

  1. Read and fully understand the warning below.
  2. If you have an old-bootrom 3GS and are already unlockable but want to get to 4.2.1, please wait til we release an “unofficial” bundle for you.  Read no further.
  3. Read update #1 for an updated 3GS bundle.
  4. Download this IPSW
  5. Run PwnageTool to create a custom 4.1 IPSW.  Tell it you want to use the iPad baseband you just downloaded.  Restore to this custom IPSW.
  6. Install ultrasn0w through Cydia
  7. Enjoy!
  8. If you don’t have a Mac, redsn0w will be released within a few hours to handle this.

FULL VERSION:

Since 06.15 is a higher version than 05.14 or 05.15 (where AT+XAPP is gone), anyone stuck at those versions can simply upgrade to 06.15 to unlock again!  Luckily for us, Apple *still* provides the iPad FW 3.2.2 with this vulnerable baseband right from their own servers. (Grab it now, before they take it down!)

We’ve been busy updating both PwnageTool and redsn0w to make the baseband update as seamless as possible.

  1. First up is “PwnageTool 4.1.3 Unlock Edition”.  It has a special dialog box which will ask you if you want to update to the iPad baseband.  You must already have the iPad 3.2.2 IPSW on your computer (see the above link)….so just point PwnageTool at it (or let it find it on its own if you’re in “simple” mode).
  2. Directly after PwnageTool 4.1.3 is available, the official ultrasn0w repo http://repo666.ultrasn0w.com will be updated with ultrasn0w 1.2, which covers iPhone 4 baseband 01.59.00 and iPhone 3G/3GS basebands 04.26.08, 05.11.07, 05.12.01, 05.13.04 and now 06.15.00.
  3. Finally, we’ll release an update to redsn0w today for those without Macs and can’t run PwnageTool.  The new redsn0w will give you the option to update your baseband to 06.15 too.

WARNING — YOU DO THIS AT YOUR OWN RISK!  PLEASE UNDERSTAND THE CONSEQUENCES OF UPDATING TO 06.15.

  1. There is no way to come back down from 06.15, and there’s no hiding the baseband version from Apple.  You’ll be voiding your warranty in a very obvious way.
  2. If some future baseband comes out with a critical fix, you won’t be able to update to it if it remains down in the 05.xx sequence (then again, you wouldn’t update to it if you wanted to keep your unlock anyway).
  3. Starting with FW 4.2.1 if you have 06.15 on your iPhone you won’t ever be able to restore to stock firmware (it will fail).  You’ll need to only restore to custom IPSWs (then again, if you’re unlocker you should already be doing that).

Certainly don’t update to 06.15 if you don’t need to!  Only do this if you need the unlock and you’re stuck on 05.14 or 05.15, and you’re willing to assume the above risks.

This PwnageTool also contains a 4.2.1 bundle for iPhone3G owners…for all else, it’s still only 4.1.  If you have an iPhone3GS with an old bootrom, the new redsn0w will handle 4.2.1 for you (in fact it covers 4.2.1 for all devices, even though some of them are still tethered at 4.2.1 until @comex can work some untethering magic).  iPhone3GS users with old bootroms who want to go to 4.2.1 should not use this PwnageTool! Update to stock 4.2.1 first, then use the upcoming redsn0w to update your baseband.

Speak in English, please !

  • Instead of finding new exploit in iPhone baseband, Dev-Team will replace it with iPad baseband 06.15.00 which served 2 purposes: give your iPhone new baseband but same old exploit (hack-able). That reminds me of this sentence: “Old wine, new vase”
  • Once update to 06.15.00 baseband, you will not be able to restore to stock firmware until Apple release new firmware with higher baseband than 06.15.00 (Ex:06.35.05 or 07.00.05…), which also means that you will void your warranty 😦
  • If you want a simplify/smooth unlocking experience and own iPhone 3GS, wait a little more for updated PwnageTool, or the OSX version of redsn0w. Patience is the key 🙂
  • You will need to download both iPad firmware 3.2.2 and iPhone 4.2.1 to be able to start the unlocking process. Then jailbreak with PwnageTool 4.1.3 and unlock with Ultrasn0w 1.2

How to Jailbreak iPhone/iPad/iPod with LimeRa1n

In Apple device on 10/10/2010 at 1:01 AM

Update: Limerain might not support iPhone 3G and 2G. BEWARE !

That’s it, folks ! GeoHot came back with awesome jailbreak tools for all iOS device current version. And the best part is he used different boot-room exploits than the Shatter exploit (chronicdev team). Now some of you may say GeoHot should save it for the next release iOS 5 or iPhone 5…but in my opinion the release of Limera1n could only strengthen the healthy competition between jailbreak/unlock teams and individual hackers. It is alway better to have two or more providers than one, eh ?

Warning:

  • If you rely on unlock (ultrasnow), stay away ! Cuz Limera1n is ONLY jailbreak tool and available only for Windows
  • Limera1n is JAilbreak tool only and beta version so you may experience some glitches. Here is the copy from Limera1n website:
  • known bugs
  • 3GS new bootrom is broken, fix pending. Need to restart to get the Cydia icon to show up after installing. Some people still don’t have windowsbeta iOS versions aren’t supported. Uninstall in limera1n app doesn’t work, you can just delete the blackra1n.app directory”
  • Allow the instructions in the box, sadly limera1n isn’t one click. That’s the price of unpatchability, as usual, donations appreciated but not required still in beta, pardon my ragged edges.
  • AppleTV is technically supported, but theres no apps yet
  • zero pictures of my face

How can i do it ?

  • Go to limera1n website and download the software
  • Extract and follow Limerain’s instruction to jailbreak your iphone

Guides from Redmond Pie :

Limera1n has been released for all iOS devices including: iPhone 4, iPhone 3GS, iPod touch 4G / 3G, iPad running iOS 4.1, and iOS 3.2.2 respectively. Limera1n is currently available for Windows only, however a Mac and Linux version will be available soon.

The following instructions will help you jailbreak iOS 4.1 on iPhone 4 and iPhone 3GS using Limera1n.

NOTE: If you rely on an unlock, do not update to iOS 4.1 yet as doing so will upgrade your baseband, making it impossible for now to unlock. Either use TinyUmbrella to update to iOS 4.1 without update baseband (instructions here), or wait for PwnageTool which will help you cook custom firmware files for iOS 4.1 without the upgraded baseband.

Step 1: Download Limera1n from here.

Step 2: Connect your iPhone via USB to your computer and click on “make it ra1n” as seen in the screenshot below.

Step 3: Now follow the following steps in this order:

  • Now wait for the device to enter recovery mode:

  • Now hold “Home” + “Power” buttons:

  • Release the “Power” button:

  • now wait for the device to enter DFU mode:

Step 4: Once you are done with this, you will have the limera1n logo on your iPhone’s screen. Limera1n will now inject the bootrom exploit to pwn your device forever!

Step 5: Jailbreak is done!

 

Step 6: Now start Limera1n app from your iPhone, and install Cydia as shown in the screenshots below.

Step 7: Now simply restart your device and enjoy the jailbreak!

You can also alternatively follow the step by step guide for jailbreaking iOS 4.1 using Limera1n in the video embedded below.

Unlock for iOS 4.1 (Old Baseband)
There is currently no way to unlock your iPhone on the latest 05.14.02 baseband. If you have managed to preserve your baseband while upgrading to iOS 4.1 using TinyUmbrella, you can use the existing version of Ultrasn0w to unlock your iPhone on iOS 4.1. Step by step instructions for unlocking can be found here.

Download Limera1n for Windows
Download iOS 4.1 for iPhone 4 and 3GS

UPDATE 1: Follow the step by step instructions posted here to jailbreak iPod touch 4G / 3G on iOS 4.1 using Limera1n.

UPDATE 2: Follow the step by step instructions posted here to jailbreak iPad on iOS 3.2.2 using Limera1n.

After the installation is done, iPhone will restart automatically and you should now have a fully jailbroken iPhone running on iOS 4.1.

How to enable iPhone 3g tethering with TPG network

In Apple device on 16/06/2010 at 1:24 AM

Story:

Ok so you are one of the people who finally join TPG for their attractive mobile plan ?

Me too 🙂 I signed up for TPG Premium 50$ for 1000$ cap value and 500Mb per month. The only downsize is TPG does not support internet tethering ! So i use Google to find a way around to enable tether with TPG and here are some information i collected (mostly from Whirlpool). Those are only for referencing, please refer to TPG staffs for all your enquiries !

  • Tethering is the use of a mobile device such as a mobile phone to supply Internet access for another device which is otherwise unconnected, using the mobile device as amodem. This can be done through Bluetooth wireless technology or cables (such as USB). Please go to Wikipedia for more information.
  • The DATA is included in CAP plan. It means that if you use up your 500mb data, every excess kb data will be deduced from your 1000$ CAP value and if 1000$ are used up as well, prepare to meet your biggest mobile phone bill 🙂
  • The reason why TPG does not support tethering is because TPG used Optus line and Optus restricted tethering. That is why when you enable tethering, iPhone will display the message: “Please contact Optus for…” And if you do contact Optus, they will explain that you need to pay them $/month to be able to use Tethering 😦

How to do it ?

  1. Go to help.benm.at with your iPhone’s Safari
  2. Scroll down and select Tethering. Read Disclaimer first !
  3. Select your country
  4. Select your provider (mine is Optus)
  5. You can choose to install benm’s webclip or turn off
  6. Press Download and then choose Install profile

Web clip is the new feature of your Safari (same as bookmarks) . It will automatic create a new icon (in your home screen) based on your requested website. In this case, it will link to Benm’s website. For more information about how to create your own webclip, you can visit Ziphone.

That is all ! Now you can Enable Internet Tethering 🙂

Use it at your own risk :))

Blocked iPhone’s IMEI ? Not a problem :(

In Apple device on 11/06/2010 at 3:10 PM

STORY:

As ex-iPhone owner and lost , i felt completely satisfy when service staff explained about blocked IMEI option. Ok so even i lost my iPhone, that bastard who stole my phone can only use it as an iPod Touch :)) and judge from iPhone community, there will be no ways to fix that wonderful protection ! An IMEI blocked iPhone will be useless in Australia for at least 2 years. YES !

WHAT I KNOW:

In case you don’t know about IMEI, please visit FAQAMTA website for more information. Here are some common answers i copied from them:

  • What is an IMEI number?

The International Mobile Equipment Identity (IMEI) number is an international identity number used to uniquely identify a mobile phone. The 15-digit IMEI number is an electronic fingerprint transmitted every time a phone is used, which reveals the identity of the mobile handset. They are independent of phone numbers and are usually stamped beneath the battery on the back of the handset

  • How can I find out my IMEI number?

Mobile phone users can also check their 15 digit IMEI number by dialling *#06# on their mobile handset

  • Where can I check the status of my handset to confirm whether it is blocked or unblocked?

You can check the status of your handset by going to the AMTA website for lost and stolen IMEI status queries

BUT ! YES, IT IS  BIG BUT !

The truth is these iPhones can still be used on everyday basic ! Why ? Because i once had a blocked iphone with full functions: calling, messaging…I bought it from eBay as a broken iPhone and intended to fix its smashed screen. After 2 hours  replacing its screen and hours restore, switch to DFU mode (Big thanks to my friend ‘s help), i got it worked :-). Eager to try out the new phone, i took my friend sim, plugged it in and voila normal calls and messages. I was so happy that i could fly up in the air 🙂 I got a bargain !

Soon my friend made me drop to the ground by checking its IMEI. “Your phone was currently blocked by…” WTF ? Why it still could call and message ? Thinking it took some time for mobile phone service to kick in, i leave it there for 2 hours. When i got my hand on the phone again, it still functioned normally 😦 However, when i restart it, the magic disappear 🙂 I spent my next day to experiment and figure it out that: The only reason why BLOCKED iPhone WORKED is i had used some kind of “sim-swapping” method when i quickly swap sim from normal working iPhone to my phone. As long as the signal did not run out or the iPhone did not suddenly restart, Blocked iPhone can be used normally. And i thought i could laugh at the one who stole my phone 😦

ENDING:

Luckily, the guy who sold the iPhone agreed to refund but now i got extra iPhone screen as a paper weight 😦  It seems that with every lock is created, there are always keys to unlock ! And with this simple trick i found, i can image underground market might have some kinds of “Unblocked device for iPhone” already 😦

For example a quick swapping sim slot that piggy back iPhone back case. When iPhone is blocked, you can simply switch on the device, pull out your sim, put it into swapping sim slot, wait for the green light then put it back and there you go ! 30 seconds at most. And to think that Apple iPhone is the most security smart phone 😦

Other ways to unlock/jailbreak iPhone 3G firmware 3.1.3 baseband 05.12.01 Bootloader 5.8

In Apple device on 03/05/2010 at 2:51 AM

Update:

  • Bad news folks, some of the guys pointed out this iPhone has bootloader 5.8. That is why this method worked 😦
  • So to make sure you can UNLOCK the device, you need to download “f0recast” software from ih8sn0w.com.
  • Run this software, it will tell if you are able to downgrade your baseband and unlock !
  • If yes, run Cydia and search for “Fuzzyband Downgrader”  install and run. And Then let it Sn0w !

Intro:

Yes you read it right, folks ! I am able to install blackrain into my friend iPhone 3G firmware 3.1.3 baseband 05.12.01 sucessfully. And after having blackra1n appear in my friend home screen, the rest is just deadly simple: install Cydia and Unlock phone are 2 fingers away 🙂 The phone specs before the unlock is: Firmware 3.1.3 (Update through iTunes) baseband: 05.12.01 and after the unlock: Firmware 3.1.2 (7D11) baseband: 05.12.01

How can i do it ?

I guess it was my lucky day 🙂 You will need:

  1. iPhone 3G firmware 3.1.2
  2. Blackra1n from Geohotz website
  3. Patience and time cuz you will need to restore the device 3 or 4 times

Ok enough typing here they are:

  1. Connect your phone to iTunes and do normally downgrade to firmware 3.1.2 (Shift click restore)
  2. Ok and when you nearly finish, iTunes will display some stupid errors: 16xx or 2…. It is normal !
  3. Now your iPhone should stuck in Recovery mode like this picture:
  4. iPhone recover mode
  5. That is a good sign. Now next is very long process: What i basically do is run Blackra1n again and again until you can see GeoHotz picture appear in your screen. And then your iphone will have his wonderful application ! Remember that if the iPhone appears black screen for 10mins after you press Make It Ra1n, just reboot it by holding the 2 buttons and run blackra1n again !
  6. Based on my friend phone, it normally took me about 2 times to get GeoHotz screen.( I did the downgrade process 5,6 times to make sure and they were all sucess 🙂 It seems to me that Apple fix is not good enough to 100% block GeoHotz exploit

I did it. How about yours?

  1. I need someone to confirm that this method work on every iPhone accidentally upgrade to 3.1.3. So please if you are successful please post your result
  2. Also i want to confirm that the solder joint i did to my friend’s phone has nothing to do with this downgrade. (My skill at solder is terrible so i am not willingly unsolder and solder the joint myself 😦

Final Hope: How to fix Weak or No signal on your iPhone 3G

In Apple device on 29/04/2010 at 5:32 AM

Story:

My friend asked me to take a look at his faulty iPhone after he decided to change its cracked LCD screen by another one in eBay. The iPhone appears to function normally EXCEPT it rarely gets any signal. My friend tried any possible ways he could: restore, reset setting, jailbroken/unlock or even reconnect all the cables/connectors but nothing ! The phone sometimes can get 2 or 3 bars then immediately switch to “No service”. It is basically an iPod Touch with Wifi 🙂 so we made a bet: If i can fix the problem, his sweet Honda CBR250RR will be mine for 2 weeks !

Warning:

I do this for fun so please consider my repair tips as entertainment only. Please follow your Apple repair guide to have your iPhone fixed. With others who are willing to ruin your iPhone, this is your chance 🙂

What i did:

Based on all the scratches and bends on the iPhone’s surface, i must say that it had been brutally opened by my friend 😦 In the next 2 days, i ended up doing exactly as he did: Restore setting/network/phone but no luck at all. I even carefully dissemble the iPhone completely and reassemble again with the hope of  getting it right but no luck. I know that sometimes it can get a signal so it must be something wrong with the signal receiver hardware ! Keep that in mind, i tried my last search in google and found this thread in Modmyi.com. Spinningjc member pointed out the “copper tooth” in main-board which my friend damage ! Here is the image:

Click the image to open in full size.

And yet despite i tried to solder another copper piece into the missing position (i never solder before:(, the phone still displayed the damn thing “No signal” . Ok so now i know that something definitely missing from the main board due to my friend over-kill force. Continue digging in that Modmyi.com thread, i found a link to mauron.net and find impressive “how to” from this bloke. Realizing that i had the same situation as his iPhone, i gave it my last shot and Sweet Zombie Jesus ! The phone gave me full 5 bars signal ! I immediately used the phone to call my friend to arrange for motorbike pick up. Up to now, his phone has worked flawlessly and i also enjoy his Honda :-). Below is the picture of what you need to solder (Remember to scratch the track to expose a copper color line):


Summary:

  • Please check to make sure if you do damage this main board area (Particularly when replace LCD screen)
  • The “copper tooth” does NOT contribute to signal receiver
  • Try to buy a small tip solder to make the work easier
  • All credits and pictures go to Modmyi.com, Mauron.net and especially the guy who found the solution for my friend problem. And if you can resurrect your iPhone using this guide, please leave comment so other people will be benefit 🙂
  • Long live Google 🙂

Update:

  • Seems the solder joint has been activated Wifi the whole time. Even when i tried to turn it off, the device can still connect to the internet
  • (Sorry folks, it did because i still connected to 3G)
  • The device works flawlessly now 🙂
