After to many customs roms installed in my phone i decided to start from the stock 1.9 again.
Every thing was good in the other steps (bootloader, twrp), until i flash MIUI 8.8.11.
After something goes wrong with the MIUI installation, i decide to star every thing again, but even TWRP was accessible anymore, only fastboot was ok.
After tryed to force edl mode without succes i forced port 9008 pressing power + vol up.
Everything was good and the rom was flashed.
The message "download succeed....finished download" appeares and the phone restarted.
Boot loader was locked again and the fasboot was inaccessible again, showing that the rom was really flashed, but after ZUI logo appeares the phone turned off.
I flashed too many others stock roms by qfil after that and the problem always appear again.
All the flashes concluded, but the phone turn off after ZUI logo appears.
I don´t know what to do anymore
Thank you if you have any tips
