Resource: Not Guarantee Methods To Relock Your iPhone
September 25, 07 by You Teck
With Apple targeting the unlock iPhones by tightening the security on their firmware, owners of the unlock iPhone would most probably face the issue not being able to get their iPhone updated in the next firmware release. Thus, the guys from TUAW (The Unofficial Apple Weblog) has gathered several resources across the net to present the following method to relock the iPhone. Here’s the excerpt from their site:
- (Take out your SIM from your iPhone.)–Still checking on this step.
- Download the 1.0.2 firmware to your computer and unzip it. It uses a .ipsw extension but your unzip program should still work. Change the extension if you have to.
- Extract the ramdisk as such: dd if=009-7698-4.dmg of=ramdisk.dmg bs=512 skip=4 conv=sync
- Mount the extracted ramdisk.
- From the ramdisk, copy /usr/local/bin/bbupdater, /usr/local/standalone/firmware/ICE03.14.08_G.eep, and /usr/local/standalone/firmware/ICE03.14.08_G.fls to your iPhone. Place these into a folder on the OS partition (such as /bbupdate) and not into a folder on /var/root. The /var/root partition is set noexec and you cannot run programs from there.
- Disable com.apple.CommCenter.plist–either using UIctl or launchctl: launchctl unload /System/Library/LaunchDaemons/com.apple.CommCenter.plist
- On the iPhone, navigate to the folder where you stored bbupdater and the eep and fls files.
- Run bbupdater as such: ./bbupdater -f *.fls -e *.eep
- Reload comm center: launchctl load /System/Library/LaunchDaemons/com.apple.CommCenter.plist
- Reactivate with your favorite AT&T SIM. I personally like using iASign.
However, they’ve stressed that it’s of paramount importance that you wait for a while more for something more concrete as the above methods has its fair share of success and failure. If you’re wondering why should you even bother about the updates, here’s what Eric from TUAW says:
Q:”Do I have to update my iPhone when the next firmware is released?” — A:No. But then you’re kind of sticking your iPhone into a time warp. Everything else will change but not your iPhone. And I don’t see there being a parallel development effort on the part of hackers.
We wish the best of luck for the guys from TUAW to be able to come up with a solid method as soon as possible. via [TUAW]
