Usage of img4lib to get iOS 9.0.2 Ramdisk for iPhone 6S+

[ellegance]

Hello, @xerub
I found your library as a tool for decrypt Ramdisks, Kernel, iBSS, iBEC from iOS firmware. But there were no mentions about relatively fresh iPhone's, only 5 and older. I have iPhone 6S+ with iOS 9.0.2 which is stucked on bootloop due to file modifications on System partition. The problem to deal with is to get access to device System partition and revert file modification. Device was jailbroken, but unfortunately USB SSH does not load before it gets stucked on bootloop.

If I understand correctly it is possible with loading SSH Ramdisk from DFU mode using checkm8. Could you please clarify, how img4lib could be used to get SSH Ramdisk in my case?
Thanks

Hey man, I made a tool for it: https://github.com/danieltroger/telnetd_ramdisk/

Hope it's still relevant

@ellegance it's best to create a custom ramdisk, using an Apple ramdisk as a starting point.

The flow is outlined below:
img4 -i apple-ramdisk.img4 -o rdsk.dmg

<add your own tools to rdsk.dmg: ssh, etc>

img4 -i apple-ramdisk.img4 -o my-ramdisk.img4 -R rdsk.dmg

Good luck.
