Yes, the jailbreak procedures is similar to older version of Pwnage Tool that I have already covered. But I think it still deserves to write a complete guide, particularly for those readers who have already followed my guide http://www.simonblog.com/2008/10/07/complete-guide-jailbreak-unlock-iphone-for-firmware-21-using-pwnage-tool/ to use Pwnage Tool to upgrade to firmware 2.0/2.0.1/2.0.2. Okay, let's get started. Preparation for the upgrade 1. First, make sure you have upgraded to iTunes version 8.0 and backup your iPhone data by synchronizing it with iTunes Tip:You can download older version of iTunes here if Apple already releases a newer version of iTunes at the time you're reading this post. 2. Download all the files including Pwnage Tool 2.1, bootloader and iPhone firmware 2.1 Please use Firefox to download iPhone Firmware 2.1. Do not use Safari as by default it'll unzip the IPSW file 3. Launch PwnageTool_2.1.dmg and copy "PwnageTool" to your desired folder. Also, extract bootloader to the same folder. 4. Place the iPhone firmware 2.1 file to "~/Library/iTunes/iPhone Software Updates". If the folder does not exist, create it by yourself. However, in case the folder contains other firmware files, please delete them. 5. Finally, connect your iPhone to the dock/USB cable. Please keep connected for the whole pr
Chris Eissens I was planning to review BootNeuter together with the release of WinPwn. But as it still hasn't been released due to several little bugs that the developer want's to fix, i will go ahead and review the BootNeuter app first. I've had a http://iphonefreakz.com/2008/04/12/upgrade-or-downgrade-your-bootloader-with-bootneuter/ lot of people who ask me, what is BootNeuter and why do i need it. First let me explain what it does. BootNeuter let's you switch between bootloaders (for info about bootloader and baseband go here). So why http://www.howardforums.com/showthread.php/1632042-iPhone-2G-stuck-on-quot-Restore-needed-quot-iTunes-cannot-restore-Error-23-etc-etc do i want to switch bootloader? Without going into to much technical details (if you'd like, we can talk about this, just drop me a mail), for improved Google Location and improved battery life if you're running 1.1.3 error 21 or 1.1.4. People who are running older firmware versions, should not upgrade to the BL 4.6 Ok now that we have that out of the way, let's discuss this neutering thing. What is neutering your bootloader? [ad#inblog] -A neutered bootloader gives you absolute control over your baseband. The normal restrictions invoked by apple are completely removed ! -The baseband is no longer integrity-checked -Can be patched (unlocked or other custom modifications) -4.6BL will even run with patched error 21 iphone baseband ??� no need to revert to 3.9BL even with most recent firmware Secpack restrictions are removed -You are free to downgrade your baseband using bbupdater without having to run ieraser/ienew first. -No longer does the ???greater than??? (4.6BL) or ???greater than or equal??? (3.9BL) rule apply. You can arbitrarily go up and down regardless of what secpacks you use. Secpack signatures are ignored -The RSA encrypted header is no longer checked for correct hash values by the bootloader -The *.fls files can be patched and fed to bbupdater directly -A copy of the last used secpack will be saved at a03c0000, retrievable via norz or similar dumpers. Not that secpacks even matter anymore. -Your neuter selection survives iTunes restores and updates Let's have a look at the app Bootneuter itself Warning ! You must be on fw 1.1.4 to be able to bootneuter your bootloader with BootNeuter !! 1) You can locate the app in the tools category of the installer, if you haven't pwned your device.. 2) Before you launch BootNeuter, switch off your Wireless. and make sure your battery is high enough. 3) Let's launch the app. 4) While the app starts it will determine your settings. 5) when the app stars you can chose your Bootloader version. If you are on 1.1.3 or 1.1.4 and see that your baseband is 3.9. I recommend t

As far as I know, the phone did work until recently, was not dropped, but suddenly got stuck at this screen: The owner is not computer savvy, and is unsure whether the firmware has been updated (by chance or not). Right now the phone is stuck at the "Restore needed" screen. What have I done so far: Put it in DFU, iTunes finds is, and tells me it needs to be restoed; I have downloaded the 1.1.4, 2.2, and 3.1.2 firmwares for the 2G; I have tried to SHIFT+RESTORE many times, and every single time it ends up giving me error 23. I tried all of the above-mentioned firmwares, have tried with iTunes 9.0.3, 8.2 and 7.5 MANY times - with the same result: Error 23. There is something interesting: when I tap the "i" on the screen, it shows a windows that says: IMEI: Unknown, and ICCID: Unknown I have searched online for a whole day now, and people say that this is related to a hardware problem with the modem; others said that it could be fixed by flashing w/ older firmware and older iTunes version - both of which I have tried... So bottom line is that after a
