What do you mean
download a rom and just flash it that's all
You don't have to do clean flash cuz you had already do that

I flashed a custom pie rom (stock based) then flashed a stock pie and didn't lose root

As you wrote 'Custom pie' and no stock rom. That is the big difference...
But why not try it out by your own?

I had to flash a custom pie rom in order to flash a stock pie. I tried flashing a stock pie from a q custom rom and It wouldn't flash.

I posted this logcat about sound issues. Just found out that if I flash a rom and just let it sit in twrp for awhile, sound seems to work. Could u look at this? Thanks

Hardly needs help

Hi All,
I locked the bootloader of my redmi 9 power and after the lock device doesn't start and shows "the system has been destroyed".
I can only enter in fastboot. Is there a possibility to fix it?

Once you relock a bootloader a phone only can get booted into its original Stock ROM. Hence re-flash the original Stock ROM.

Find your system on the internet and download it. There are solutions somewhere for sure. Did you browse this forum?

After flashing the stock rom can I then flash a custom rom ?

Why not? Give it a try.

It won't harm the device right? This is actually my only device.

Re-flashing Stock ROM never harms. Flashing a Custom ROM - what requires to have flashed a Custom Recovery before - always is a bit risky.

Can you explain how you were able to root? I may be able to build a custom rom if you have a way to flash it

I used twrp to flash magisk

You could flash a GSI probably, there are many out there

Will try it, thanks!
