Information

Okay so i recently got an Htc One m8 from a friend. It's already rooted, but I dont know if it has a custom recovery or anything. Can someone fill me in on all the important things I have to know for custom recoveries and kernals and stuff like that. I have an At&t version btw.

Q5 has a link to some nice information about HTCs
and you should do a "fastboot getvar all", it shows you all the information you should know about your phone.
for example:
Code:
C:\ADB2>fastboot devices
SHxxxxxxxxxx fastboot [COLOR="Blue"][I]<- i'm in bootloader[/I][/COLOR]
C:\ADB2>fastboot getvar all
(bootloader) version: 0.5

Assuming you have adb and fastboot setup and know how to use it.
Adb /fastboot ?

No wifi no network...

Hi everyone, I have a HTC One M8 locked on SFR (France)
The phone was on stock Rom but I changed it to Custom Rom and unlocked the bootloader but I had this issue with networks : no wifi, no data..., so I returned to Stock Rom but nothing changed.
the command
Code:
fastboot getvar all
return

but it's weird, the version-main field is empty
Maybe it's the reason of the problem?
I already tried to flash the stock recovery for VODAP203 (Vodafone FR).
Thanks for you help

TWRP made the main version disappear. Check the general section - collection of backups and firmwares. Read there and put 1+1 together. Take your bootloader number 3.16 and your cid vodap203 and match a backup from the list. My guess it starts with 1.12 or 1.54. Restore it and also flash back the matching stock recovery and then update

Thanks for your reply, I checked the files you said here : http://forum.xda-developers.com/showthread.php?t=2701376
but no one match with the bootloader or the cid number.
And what do you mean about : "Read there and put 1+1 together" ?

That was about the bootloader and cid. With those 2 you can determine the software number. Don't see your actual cid present but you can try it with the 161 backup
Take the 1.54.161 and try it with that one. No harm can be done in trying

Post your fastboot getvar all command output. Delete the serial and imei before posting !
The ruu above might work but if you are on a higher firmware and s-on the ruu will definitely fail because you can't downgrade firmwares on a s-on device !

Nice! Thank you!

HTC One (M8) in UK on US TMOB

i believe the most suitable rom and firmware for you is the one meant for your region
