Phone originally on Android 4 - probably KitKat, it was bought in late 2014.
It's had two OTA upgrades, first to Lollipop, which I used without any problems until Marshmallow came along, and then I did the OTA upgrade to that, and used it without any problems for a while.
I've never done any backups, mainly because I could never get HTC Sync Manager to see my phone when I connected it to the laptop, and because I'm lazy, and a friend told me that means there's probably unwanted bits of the old operating systems still on the phone.
I recently tried to "Restart" it when I had an unresponsive app, and it went into a bootloop. At that point I managed to get it started again (in safe mode maybe? not sure, but it started working, so I ignored the problem) and used it for a few days.
Same thing happened again - bootloop. Couldn't get out of it at all. Have tried a factory reset/restore without any success (I've resigned myself to losing any data left on it).
I can still get into recovery mode, but it still won't go any further. I asked about it on this forum a few days ago and was told that the OS is probably corrupted and will need to be restored.
The bootloader screen shows:
*** Software status: Official ***
*** locked ***
M8_UL PVT SHIP S-ON
HBOOT-3.19.0.0000
RADIO-1.29.214500021.12G
OpenDSP-v51.2.2-00593-M8974_FO.1015
OS-6.12.401.4
eMMC-boot 2048MB
Dec 17 2015,14:15:48.0
My question is this:
In Recovery mode, there's a menu option to "Apply update from SD card".
Can I use this by copying OS 6.12.401.4 to the root directory of an SD card, slotting that into the phone, and selecting that option?
If I can, then what format should this be in, and what format does its name need to be in?
If I can't just do that, what's the idiot's guide to what I need to do to get the phone working again? I don't have any great desire to root it, I was quite happy just using the phone as it was, when it was working.
Any help would be appreciated!
