    Default Can Pwning destroy your phone?
    I was just wondering how low level messing with the bootloader is. Say u somehow currupted your bootloader during a write, toddler yanks out USB, power surge, etc...is your phone done? or is the DFU still intact to where it can rewrite the bootloader? Just wondering I havent messed with it yet, but am curious as to the worst case scenario. I know with jailbreaking the worst thing is a restore. Let me know what you guys think/know!

    I guess nobody knows...maybe ill research on the google and post my findings

    Bootloader - This is a very small program in non-volatile memory (can be flash, often not eraseable) that 'bootstraps' a processor startup, and calls the main (usually much larger) program. The bootloader also provides a protocol for obtaining and storing an updated version of the main program. Normally, the bootloader is not updated. It is the main program that gets upgraded, not the boot loader. Also, if something happens during the update of the main program, the bootloader will always be there to save you and restore the main program with the preferred one. However, when you update the bootloader, if anything undesireable happens, the bootloader will be corrupted. This means that the processor will not restart at all. The phone is dead for all intents and purposes at this point. Source.

    Apparently if you currupt the bootloader...the only way to fix it is to replace the iphones communication board which runs about $225 US

    ipwnrs....proceed with caution....someone correct me if Im spreading mis information

    the pwning process isn't touching your bootloader, only if after you pwn your phone and restored your phone with the custom firmware and you've installed BootNeuter, then upon starting BootNeuter, you decided to upgrade/downgrade your bootneuter or unlock your phone. That process can completely damage your phone IF you somehow interrupted the process.

    This is the same with unlocking using ANY of the available methods out there, ZiPhone, iPlus, iLiberty

    It depends on if you interrupted it during the "FLASHING BOOTLOADER - DO NOT INTERRUPT" part of it. If you did, and your baseband's not responding when you run bootneuter again, then you're toast unless you want to open up your iPhone. I think it's still possible in most cases to recover with a method based on the hardware unlock, but it's not really documented. You'd have to climb a mountain in the Himalayas to speak with a guru about it, etc.

    BootNeuter and its accompanying documentation pretty much begs you to not interrupt bootloader flashing.
