[Mate 8 Q&A, Help & Troubleshooting] speedy101:
WOOOT This worked but HOW!?! And what is this backdoor hack to load the image (see log ) ? LOL!

ps: the downloaded file has a different name: NXT-AL10_M00A102_Factory_firmware_Global_Nonspecific_Android_6.0_EMUI_4.0.dgtks

in the here above filename is wrong/different: NXT-L29_NV_partitions_backup.dgtks (Corrected by TS)

Corrected: ps I checked the MEGA download file with the DC-Unlocker download ( https://files.dc-unlocker.com/user.html?v=files/57694006a60d7 )

they are the same:

K:\>fc /b NXT-AL10_M00A102_Factory_firmware_Global_Nonspecific_Android_6.0_EMUI_4.0_DC_UNL.dgtks NXT-AL10_M00A102_Factory_firmware_Global_Nonspecific_Android_6.0_EMUI_4.0_Mega.dgtks

Comparing files NXT-AL10_M00A102_Factory_firmware_Global_Nonspecific_Android_6.0_EMUI_4.0_DC_UNL.dgtks and NXT-AL10_M00A102_FACTORY_FIRMWARE_GLOBAL_NONSPECIFIC_ANDROID_6.0_EMUI_4.0_MEGA.DGTKS

FC: no differences encountered

anyway

i loaded up the downloaded NXT-AL10_M00A102_Factory_firmware_Global_Nonspecific_Android_6.0_EMUI_4.0.dgtks from MEGA ( see download link from djmitza222)

into DC 0.0.35 and this happened ( see log )

options:

Force upgrade OFF

not erase NV ON

Not Erase oeminfo ON

after this the Phone boots ands is all OK and i have C900B320

ps: My phone was bootloader unlocked and FRP Locked

i dont have installed some sort of virus / backdoor ?!

and can somebody explain why i spend days with tools and stuff but this actually worked ( for 15 euro ok ) ??
