I decided to turn to original MM rom then. But first i wanted to replace the JUI TWRP (One of the roms has installed it) with 126.96.36.199 TWRP. I make the flash without any errors. But after the restart of the device, JUI twrp logo appears again. But phone not go in the recovery. Just stays in Nougat twrp logo.
I tried to go in bootloader mode. Fails.
I tried to shut the device off. Fails. Its turn on by itself and stays at JUI recovery logo screen
I tried to go in recovery mode again. Fails.
I tried to put it in EDL mode. Fails
Then i decide to let the battery drain, and after that i put it in Bootloader mode. Then....
I tried different versions of Coolpad download assistant (latest v 1.59) in order to flash a new rom. Procedure allways fails with an error at the end. (is in Chinese)
I tried QFIL but app can see the device only at EDL mode.
I tried to put another TWRP via Fastboot but with the order fastboot device says ...searching for devices. It cant see the phone when in bootloader mode. (yes a have installed all drivers including qualcom usb drivers, google drivers, generic android drivers etc.)
I tried some versions of YGDP tool (latest v.5.00) but fails with this error..
