Error: "PMT changed for the ROM"

​

Firstly,

NEVER

try to flash in "format all" mode !​

Otherwise, you will LOSE all secure and identifying infos for your device. Like IMEI and MAC.​

If you are facing "PMT changed" message, your device has an older scatter file inside it.​

This is because there is any modification to the scatter file you are using to the scatter file used before.​

There are some minor changes from scatter file of the MIUI 11 to the scatter file of MIUI 12, but nothing significant. You can ignore it.​

You have two solutions for that error:​

#1. Use the same scatter file present on the device.​

#2. Flash using "firmware upgrade" mode and a new PMT will be written.​

But, if you flash using "firmware upgrade" mode, bootloader will be

LOCKED

again and userdata will be

ERASED

.​

If you want, you can backup the state of unlocked bootloader

BEFORE

the "firmware upgrade" and then restore it after.​

Just follow this guide before the "firmware upgrade": https://xdaforums.com/t/guide-unloc...omi-redmi-note-9-xiaomi-redmi-10x-4g.4220013/​
