Soft bricked and can't flash any ROM

So , I was helping my buddy out with his Roger branded HTC One M8... He had the latest OTA, unlocked the bootloader, installed a custom recovery, and finally tried to flash ARHD 10.2.....


ARHD won't flash because it says it's a corrupt .ZIP.....
The Backup we made before flashing, recovers, then reboots back into recovery ( fails )
Any other ROM also says corrupt .ZIP...


Have never had an issue like this before, and I have no idea what to do from this point on....

Already tried recovering the backup & flashing a different ROM.


I can't find the RUU for the latest rogers ROM ( Firmware 2.23.631.2 ) so I haven't tried to flash a stock ROM.... Can you install a stock ROM from before the OTA, if you did the OTA? Or will that just lead to more issues?


Any help would be greatly appreciated! ( PHONE MODEL M8_UL )

What recovery and what version?

My first hunch would be fastboot erase cache, and re-flash recovery using fastboot. Often clears up lots of flashing issues like this. Also make sure you are using an up to date version of recovery.

Also, you can try to put the ROM on a different location such as the removeable SD and flash from there.

Rogers often does not issue RUUs, so I would not be surprised if this is the case for the M8 as well. Although I personally can't say, as its not my carrier.

That version is 2 iterations old.

But just might be a bad recovery install, it happens (and as you mentioned, or works on your phone, so why not your buddy's?). adb erase cache and install newest TWRP (2.7.1.0).

Successfully flashed TWRP (2.7.1.0)

Attempted Recovery of the backup made right after installing TWRP for the first time, failed.

Attempted to flash the same ARHD Rom as tutchthesky7, see log:
<<<Log Start>>>
E:Unable to mount '/cache'
Full SELinux support is present.
E:Unable to mount '/cache'
E:Unable to mount zip file.
Error flashing zip '/external_sd/Android_Revolution_HD-One_M8_1-.2.zip'
Updating partition details...
E:Unable to mount '/cache'

[Restore Started]

Restore folder: '/external_sd/TWRP/BACKUPS/SH45WM01930/1M8PostRoot_Recovery_2014-08-19--01-04-57'
Skipping MD5 check based on user setting. ("I'd personally verified the checksum prior to all this")
E:No partitions selected for restore.
E:Unable to open zip file.
Error flashing zip '/external_sd/Android_Revolution_HD-One_M8_1-.2.zip'
Updating partition details...
E:Unable to mount '/cache'
<<<Log End>>>

Tried flashing the sideloaded ROM, and failed with the same resulting log as seen above.

Did you fastboot erase cache before installing TWRP, as I suggested?

the log got me thinking, after updating TWRP and then clearing the cache the mounting issue seemed wierd, so I tried sideloading to sdcard0 after clearing the cache once more then installing from sideload.zip on sdcard0, which entered the ARHD install GUI. so now I just need a confirmation on whether installing from sdcard0 is dangerous as a reformat mid install will erase the zip im trying to install from. soft brick is bad enough, really want to avoid an expensive paperweight.

I'm still in the menu, waiting for more seasoned minds to respond before I go through with it.
