Please note that: This phone has never been reprogrammed/rooted/changed in any way/anything else like that. It is as stock as the day I bought it 2 years ago. I am happy to do whatever it takes to resolve the issue below.
The phone can be turned on, but will only do one of the following things:
-Black screen, old-style htc logo in centre, short vibrate, turn off, endlessly loop.
-White screen, green htc logo with "powered by android" text at bottom, short vibrate, turn off, endless loop.
Holding volume up+down together gets me to the boot screen with the following:
* Software status: Modified LOCKED S-ON *
to previous item to next item to select item
REBOOT REBOOT TO BOOTLOADER BOOT TO DOWNLOAD MODE BOOT TO RECOVERY MODE POWER DOWN
When I plug in the phone to my PC, the USB notification sound plays, but only if the menu above is showing.
Selecting any of the options reboots the phone and goes back to the menu above, with the exception of the "BOOT TO RECOVERY MODE" option. Selecting that takes me to a black screen showing the old htc logo in the centre and:
Failed to boot to recovery mode Press volume up or down to back to menu
This build is for development purposes only. Do not distribute... etc.
Pressing vol up/down at this point gives me the first mentioned menu screen, but below the * S-ON line is Security Warning *.
So, my question is:
1) Can I get my phone out of this loop and back to booting normally?
