Question Flashing ROM with Lock Bootloader - Xiaomi Poco X3 Pro

Hi I’m complete newbie , earlier I experience bootloop then I saw a blog that if I wipe data using stock recovery the problem will be solve but its not. So is there a chance that I can flash stock ROM with lock bootloader? Thanks in advance if someone will answer.

Yes it's called stock rom so you can flash with locked bootloader
But if is a custom rom you can't

How can I flash stock rom with lock bootloader sir ? what tool should I use ? TIA sir

Xiaomi flash tool

You can't flash anything with locked bootloader, not even stock rom.

if your bootloader is locked you can't do anything. After you setup a phone you must turn on usb debugging for future purposes like your problem right now.

Download this full stock firmware http://www.androidfilehost.com/?fid=23134718111254196 then use Odin to flash, once done take the OTA and it should be fine. BTW, once upgrade to 4.3 your bootloader will be locked permanently meaning you can't flash custom firmware (rom/kernel/recovery), the only thing you can do is root with saferoot. can be found here http://forum.xda-developers.com/showthread.php?t=2565758

If you still want to install custom firmware then DO NOT TAKE THE 4.3 OTA UPGRADE. If you decided to flash custom rom then after flash stock MF1, you need to unlock bootloader, root, flash recovery then flash custom rom (most custom rom already rooted so you probably don't need to root). Your phone status will be CUSTOM.

Haviing only used Odin when I initially rooted my phone a year ago, I need to ask some specifics on your instructions.
1. Do I boot the phone into Download mode when flashing?
2. Do I flash it by selecting the PDA box and selecting the file there?
3. This will make my phone basically "out of the box" and back to stock recovery, correct?
Thanks in advance.

The stock root rom is probably the most stable one. http://forum.xda-developers.com/showthread.php?t=2591895 just follow the instruction on this link.

so i dont need my flash my backup stock rom???
Relock bootloader through Flashtool, click on "BLU" and relock. After that flash the right stock .ftf file, so you'll have locked and unrooted device. Like just buy.

[Q] Flash Customised Firmware on Carrier Device

I'm still confused about this. Can we do what the title says? Been searching it for a while and I can't find any answers because probably no one asked this. Thanks
Yes you can. Without root you can flash FTF,s. With root & recovery you can flash sony stock based roms. With unlocked bootloader you can flash custom kernels

Ah thanks. Always thought there would be a conflict when flashing a generic firmware on a carrier phone.
