I've been trying to flash a new ROM to my Evo V 4g and this is my first experience with it. However, in the process I somehow got my phone to a state where it bootloops with every single ROM I attempt to flash (including restoring it to the original) and I'm not sure how to get it to stop.
Here's what I've done/tried so far:
1. Followed these instructions
to unlock with HTCdev and flash the TWRP2 recovery. I also used them to flash a new ROM (the unofficial CM10 for shooter, which I substituted for the SU patch). I did not do S-OFF, which I think is what's causing the problem.
2. Restarted the phone. The CyanogenMod animation came up and kept playing until the phone's battery died.
3. I wiped the system, data and cache and flashed the recovery.
4. Restarted the phone, the Virgin Mobile splash screen came up and stayed, but the phone would not boot.
5. Attempted to flash Harmonia and Midnight ROMs, which both bootlooped.
6. Wiped and tried recovery again. Now I do not even see the Virgin Mobile screen. The white htc screen will appear followed by the htc "quietly brilliant" screen, then the phone will turn off and start this again... and again...
7. Tried to switch to S-OFF with these instructions
, but I cannot get into the GUI to enable USB debugging and use the ADB.
8. Attempted to flash the RUU with these instructions
. I tried running the RUU.exe from my computer first and then tried to flash the .zip from my phone, both failed.
9. Flashed a copy of the stock ROM, obtained here
. The phone still bootlooped.
10. Formatted the SD card (but saved the recovery files first), tried recovery and the RUU again.
I've read through every forum/guide I can find but nothing seems to fix the problem. I'm running out of ideas... does anyone else have suggestions?
