[Xiaomi Mi 8 Questions & Answers] Theevanz:
I tried again but to no avail. Do i need to do anything before the fastboot?

So heres what i did :

Did not wipe anything or format device (Device was already in MIUI 11)

Power off

Went to fastboot

Got a global fastboot Rom (dipper_global_images_V11.0.6.0.PEAMIXM_20191022.0000.00_9.0_global)

extracted 2 times with 7zip

Put the adb/fastboot files into the extracted rom

Clicked on flash_all.bat

Device rebooted but the issue was no solved

Heres what i realise :

i opened the flash_all file and tried to find the sentence to flash persist but i cant find anything tat says flashing persist . heres my flash_all file from the extracted folder. Should i add a line that says to flash persist?
