I have recently had a bootloop, that was deemed "unrecoverable" by HTC
Ok, so first things first,
YOU NEED TWRP!
*i dont know what it is, but the commands only seem to work on twrp in different situations*
This android revolution ROM http://www.mediafire.[com]/download/58f2vid3okfonn7/Android_Revolution_HD-One_X+_8.0.zip
*part of the reason for my bootloop (apart from wiping the os) was a low hboot (1.35) and this works with 1.29+*
all drivers, and CWM universal drivers (dont ask how this helps, it just does
wipe userdata, cache, dlavik cache and system
put the rom in the same folder as adb fastboot
extract the boot image (if s-on)
open a text document
adb push Andriod_Revolution_HD-One_X+_8.0.zip /sdcard/
Now save it as a batch file
boot into twrp
mount all the options (system, data, cache)
open file manager *in advanced menu*
mess around for a bit looking at different files
do a advanced wipe, (with data, cache and dalvik cache
go back to the menu
Run the batch
(The reason for this is that you dont have to retype if it fails)
if it doesnt work, restart recovery, unplug, plug back in
when it takes a long time to say anything in CMD, it has worked.
Leave it to complete
Go to install zip from sdcard
select the ROM
just choose whatever install options.
now, DO NOT SELECT REBOOT! PRESS BACK!
REBOOT INTO BOOTLOADER
go into usb fastboot
make sure it dont say "battery level too low to flash." if it does, leave it to charge
OK, hard part over
TIME TO FINISH THIS UP!
Now you may be thinking, o, this is just "fastboot boot boot.img
but its not, you MUST use "fastboot flash boot boot.img" (dont ask why either)
select reboot system.
It takes 1-20 mins to boot first time, so be patient.
You have successfully un-bootlooped your htc one x+
i dont ask for donations, just a thanks
