Several issues - Bootloop, can't unlock bootloader, can't restore to factory..

[yetep]

Hey Guys,

Hoping someone can lend a wee hand :

Got an HTC One from one of my friends to attempt to repair for him, getting nowhere. The symptoms all started when he did an OTA upgrade last night. I'll try best describe the issues :

1. The phone bootloops and almost appears to have factory restored. By this I mean it gets past the initial boot screen, presenting me with an "Android is updating, optimising 1 (through to) of 5 applications".

2. Upon completion of this cycle it will load to the lock screen. I then have roughly 10 seconds of life left until the phone restarts altogether, performing all of the above again.

3. I can't unlock the bootloader at all. It'll load to fastboot easily and stay there for as long as I want, however I've tried to use HTCDev about 20 times using the unlock token they have sent me (several times over) to no avail. The screen gives me the "do you want to continue?" message, I select yes, and it reboots. After rebooting and then going back into fastboot/bootloader, it's still showing LOCKED.

4. Booting it to safe mode gives me about 2-3 minutes of life, however I can't get ADB to load as it won't load USB Debugging or connect properly to the computer in safe mode to push a custom recovery to then try a custom FW.


Any ideas what I can do guys? Thanks in advance.

If it helps, here is the info on the bootloader screen of the screen :

*** LOCKED ***
M7_UL PVT SHIP S-ON RH
HBOOT-1.55.0000
RADIO-4A.21.3263.04
OpenDSP-v32.120.274.0909
OS-3.62.771.3
eMMC-boot 2048MB

Cheers!

Can you post a fastboot getvar all minus your imei no and serial no, also try fastboot erase cache

 

[yetep]

I'll do that as soon as I'm back home, thank you!

I've tried clearing the cache through fastboot, essentially the same result. Be back soon with the log

@nkk71 got any ideas mate?

Can't S-OFF cause I can't boot properly, can't unlock bootloader cause it never works. nightmare!

As SaHiLzZ mentioned, send it in for warranty, because even if you get it unlocked and even if you get a stable ROM on it, you will very likely fail to S-Off;
3.62.771.3 H3G__001 and 3.63.111.6 (T-Mo Germany), are two variants that firewater and/or rumrunner don't work with.

So off to the shop! and good luck.

Thanks folks, appreciated! He bought it cause his other One was stolen, but bought it second hand so there's no warranty from a store.

HTC are picking it up tomorrow so hopefully they'll be able to do something
Thanks again!
