Unfortunately, once in awhile, it does not boot into safe mode. Most of the time, the 3GS will boot or respring into safe mode where it can be accessed and fixed. Since the release of 4.x, many have experienced booting issues after installing a non-compatible or faulty MobileSubstrate app. It requires technical knowledge, significant computer and iPhone experience, and is NOT for the beginner or the faint of heart. It builds a new ramdisk with SSH included, uses current jb'ing exploits to download the ramdisk and access the iDevice. This process should be considered a last resort. All thanks go to MsftGuy and so many others.Īcquire SSH access to the root and user filesystems, modify and/or delete the of*****ng program, and reboot without any damage or noticeable change. It uses this reference as THE source ( Mostly iPhone hacking: Booting SSH ramdisk on new devices), adds changes for iOS 4.2.1 and lots of clarification. Warning: Significant iPhone/computer experience required!! This is an alternative approach when the normal methods don't work and all else fails. SSH, iPhoneExplorer/Browser, etc and iTunes restore are the normal methods to either restore or to gain access to a non-bootable device and implement a fix. When an iDevice won't boot, several remedies are available. Experienced users only !! If you don't know what you're doing, stay away!! Thanks to for PyBoot and for ipwndfu/checkm8 I'm illiterate in low-level stuff so all the peeps making this "a bunch of shell commands" are incredible.Emergency SSH access using a pwn'd DFU mode RamDisk (Win7-32).Also he inspired me to write script this by asking for it. Thanks to Sam Bingner for the inetutils package, we wouldn't have telnetd on iOS without him. Also a big thanks to Exploit3d for the info about the seputil commands, mounting the user fs would have been hard without his help.Huge thanks to mcg29, without his help and info I would have given up a long time ago.for his contributions of bug fixes, improvements and a big speed up to the project and his fork which I shamelessly merged into my repo.boot_rd_VERSION.sh with VERSION being the ios version You can then execute that script by running. Writes a shell script to boot with pyboot and load all needed files.Downloads pyboot in case you didn't clone this repo recursively.Compiles and signs a binary which will start telnetd and attempt to mount the rootfs and data fs with seputil.Adds inetd and other config files to /etc.Syncs the staging area into the ramdisk which it mounts (this is done to preserve symlinks and not override what exists).Downloads and patches iBSS, iBEC and kernelcache, signs them + trustcache & devicetree.Identifies trustcache/ramdisk names by mounting all dmgs and keeping the name of the one with the correct partition name.The script is based on this guide and roughly does this: Made changes to restored_external.c? Run it again! Don't be afraid Made changes to ramdisk.dmg? Run it again and answer yes. Cancelled half way? Run it again and it will pick up where it left. I have successfully tested iOS 12.0, 12.4.1, 13.0, 13.5, 13.6, 13.7, 14.0.īTW: the whole script is made to be ran again and again. Regarding iOS versions your mileage may vary. PyBoot is used for booting, so the supported devices (as of now) are: It tells you everything you need to know and do to get the ramdisk and telnet connection up and running. So you can boot a 13.0 ramdisk with 13.7 blobs. The version of the blobs DON'T MATTER, they just have to be for the correct device (ECID).
