Quite in a pickle with my old HTC Desire (bravo).
It has a broken 2.3 install (radio partition corrupted), locked bootloader, S-ON. No recovery/ADB - only RUU fastboot to work with.
Unlocking bootloader:
get_identifier_token gives me shit in Gingerbread, needs Froyo?
Downgrading to 2.2 Froyo:
Officially made impossible. Would a goldcard help?
It would have to be made with a fake CID as there is no ADB access to get it.
Manually flashing radio:
Again made impossible. No public encryption key to extract individual signed images like hboot, radio from RUU zip with the ruuveal tool.
Raw eMMC access:
Is a RIFF Box my only chance here or is it possible to put the phone in download mode?
