Unbricking in Detail

Unbricking the Device in Detail

Before you step forward I would recommend taking out the Sim-Card

stay offline until the device is debloated

Some general information:

Bricked, but you have an unlocked Boolader

just flash Image in fastboot or if available in twrp

*** All bootloaders of Hisense devices are locked and there's no way to unlock !!! ***

Bricked & you haven't got an unlocked Boolader

TF-Mode (microSD)

shutdown the device

press both volume buttons and then power button together

release power button and wait 10s until the update screen comes up

alternative1

shutdown device

holding volume +- and power buttons together

alternative2

shutdown while holding volume +-

press+- buttons and then power button

release power button but holding +-

wait 10sec

release +- buttons

Hisense powered by Android

wait 10sec

press power button just short

If this above won't work, then the bootloader is damaged you will need to flash the Firmware in Edl-Mode with Qfil. This always works if not hardbricked!!! So relax ;)

If you entered the edl-mode your Qfil screen should show

like step 5 from here

Then Click Tools -> Partition Manager

confirm ok

step 10

https://forum.hovatek.com/thread-31475.html

select boot partition and right mouse click

manage Partition Data

we won't backup, we want to restore the boot-image

press Load Image and browse the boot.img from the edl-Firmware above, flash it and wait until it successful is flashed

if there's a Sahara error check again here

https://xdaforums.com/showpost.php?p=77229641

Then flash recover.img and vbmeta.img

After that reboot your phone and it must boot the system.

Then Update in TF-mode to Firmware 6.09.06 (see above)

You successfully restored your bricked phone and updated the Firmware!
