So on twrp i flash my original Rom (i ever done it one time so i know it's the good one). Everithing work great, the phone restart. I want to improve the Rom step by step, and i download kitkat 4.4.4, when it's done the phone restart, load kitkat and restart. That the begenning of probleme, it reboot i here the small song, then i stay lock one start screen (Htc-Powered by android), very strange, the screen give some vibration as if it work but nothing move, locking on this screen ........ No probleme, i restart on recovery and i start on recovery factory, the phone boot, as if it load the recovery factory version, it boot again, but nothing more, locked on white screen with Htc powered by android, and the small thong.
Here's, i don't have phone since 2 days. If you have a solution to restart this M8, please help me.
Thanks in advance for your answer.

Most probably because of a very low android version installed on a high firmware version.

Post fastboot getvar all result (without serial & imei no.) to see what actually that you need.

Thanks for you answer, how can i get fastboot getvard ?

Never expect this kind of question from a "member" of XDA.
Anyway ... connect your device to pc after you put it on bootloader/fastboot mode
Open a command prompt from your adb/fastboot folder then type

fastboot getvar all

That's your problem .. you have Marshmallow 6.12.163.4 firmware but you restored a very old version and it get stuck due to too high firmware.

I don't see anywhere a backup or RUU for 6.12.163.4 around ... you need to find it.

I'll see whether I can find a lower version than make a good collection in my backup thread

Edit : you should have already make your own backup since our last conversation here : http://forum.xda-developers.com/showpost.php?p=57254494&postcount=3175 .... maybe you can contact him again.

Edit 2 : You can wait and I'll upload 6.12.163.4 backup to my backup thread (link in my signature) either tomorrow or Sunday

Arf, ok, so i will try to find this one. I hope i will get it.
I'm just asking, how can i flash this version (if i find it), since i can't access to my phone, i never do this before ?

I found this for you ....

ROM 4.19.163.2 (+ radio & stock recovery, màd par Migascalp, flash via TWRP*)

Install TWRP then install it as same as you install custom ROM then do OTA to 6.12.163.4

Thanks to @migascalp

The problem is that before i use Twrp to flash my custom rom, and now i only have the original recovery

....before i use Twrp to flash my custom rom, and now i only have the original recovery

Reinstall TWRP - https://dl.twrp.me/m8/

Download twrp-3.0.2-0-m8.img and place it in your adb/fastboot folder

connect your device to pc after you put it on bootloader/fastboot mode
Open a command prompt from your adb/fastboot folder then type

fastboot flash recovery twrp-3.0.2-0-m8.img

then you get TWRP recovery installed then proceed the rest

gotta go now ... good luck

[Aguyos]

Working great Kuala. Amazing, thanks for advices and help

 

[Aguyos]

Arf, it's not working perfectly, i can't install 6.0. It's loading, decompress, but when M8 reboot to install it make error.....
Does some one have idea ?
Thanks for answer.

 

[ckpv5]

Why error ? Did you root it ? If you root it, you'll get error.

Here is another way for you :

Install latest TWRP
Restore 6.12.163.4 non-rooted backup
Install 6.12.163.4 stock recovery
Done
