OpeniBoot for iPhone 4 (GSM) Tethered?
« on: July 18, 2011, 01:02:41 AM »
I recently jailbroke my iPhone 4 (firmware 4.3.1 8G4) with redsn0w (windows version).  I guess redsn0w uses limera1n to jailbreak the iPhone 4.

"limera1n uses a bootrom exploit to achieve the tethered jailbreak and unsigned code execution."
"limera1n uses a userland exploit to make it untethered, which was developed by comex."

I was able to compile OpeniBoot on an Ubuntu 11.04 AMD64 machine, and run it tethered.

Is it because of the jailbreak I used/available that OpeniBoot can't be used untethered on the iPhone 4?

How does this relate to iPhone's NAND porting status?

OpeniBoot is tethered for iPhone 4. Also installing it is not advisable at the moment.

Hex-Rays ARM Decompiler

Okay...wait.

Reverse engineering computer hardware, I imagine, is a very small and specialized profession.

How close is the idroid project to having a Hex-Ray Compiler?

Also, will the decompiler help with finding more bootrom vunerabilities?
