I thought of replacing android-info.txt a few days ago, I didn't think it would work because the ROM.zip had to be signed.

Thanks for everyone who has been tweeting me this in, trying it out now.

Can you do it without a GC ?
Can anyone give detailed method ?
I have to say i'm :eek: of bricking my machine :(

First of all, I have an unbranded simlock-free phone. All I did was
1. download the file to SD card.
2. rename to PB99IMG.zip
3. boot into recovery (turn phone on while holding down volume)
4. just let it load the zip file and press yes when asked to install

Easy as that!

Hi,

just one question: Did this wipe your device or not? If yes, may be I should make a backup of my SD.

Confirmed working, thanks everyone.

I just tried repacking 1.15 with a modified android-info.txt and it didn't work, this has been signed from someone within HTC.

Seems like we have people on our side :)

    I Got HBOOT 0.92.001 and when i try Unrevoked gives me the same message
    "Main Version is older!
    Update Fail!"

    Any workaround for this?
    It's stops after reboot and boot in recovery.
