Be careful for now to flash anything (bricked phone)

[billouetaudrey]

Hi,

Just for say, to be flash your phone carefully ! I flash today a rom (test) and phone go to BL ( Poco logo) and after try to enter fastboot/recovery, phone wont boot ( Black Screen) without any reason

Now it goes back to the shop for repair ( edl certainly )

So be careful for now

For a phone with level3 api for cameras and a (supposedly) released kernel source at launch they really seem not to be wanting us to modify the phone.

What did you flash? I'm thinking of flashing AOSP GSI or other modifications

What I do :

Flash rom (Pixel plus), flash boot.img(Miui boot) and format data, reboot

It's reboot to BL ( poco logo ) and stuck to BL, So I force to reboot on fastboot and never boot ( black screen )

Did the dev had a similar problem? Are you the only tester of it?

I don't have fastboot access too, no led when charging, nothing...

Maybe it's Hardware issue... The fact is I see the poco logo ( Bootloader) after reboot Recovery
So I force to reboot to Fastboot and black screen

Only me test it

So scary to flash rom on poco x3. Can it not be save by flashing rom thru miui flash tool?

You have no idea what are you talking about, so.....read before being rude with people who wanna get some help or warn us to not do what they did. No disabling AVB is necessary when TWRP for Poco X3 is used for flashing stock or custom ROMs. Format data is needed in some scenarios. The only thing you NEVER wanna do is downgrading to an earlier Android version ROM (from Android 10 to 9, 11 to 10 and so on). So, chill out and keep reading

Is there a post that states what you must not do, or must do when flashing ? Would appreciate it - previous phone was Redmi Note 3 and I could flash whatever i wanted willy nilly. Would not like to brick my new phone.
For example: ROMs for the Poco X3 mosly have the 12.0.2 firmware requirement, but i updated it to 12.0.3 already. Would i brick my phone if i flashed the custom rom anyway, or if i flashed the older 12.0.2 over 12.0.3 ?

Downgrading brick: https://www.xda-developers.com/xiaomi-anti-rollback-protection-brick-phone/
Seems it's safe to use MiFlash because it will not let you downgrade, but when you use TWRP it helps to read this article.
In other cases, just read carefully and follow step by step the instructions offered by the developers for their ROMs.
I'm not an expert, btw. I just read a lot lol

"flashing anything in an unlocked bootloader, requires from user to disable AVB (or flash a null vbmeta.img) before you boot any flashed rom ... otherwise = brick !" - WRONG in the case of Poco X3!!! The downgrading part was like a general warning, not for Poco X3 specific (even it's true for Android 11 to 10 downgrade). Seems you can read, but to understand what you read is a problem you have. I can't help you with that, sorry

The reasons Xiaomi phones get bricked when rolling back to an earlier version is because of the "Rollback Protection". Xiaomi implemented this, not to prevent modding, but to prevent resellers from flashing global versions of ROMs (which include google apps) to newely released Chinese models not available outside China. They bought phones in bulk, flashed global ROMs and sold phones as if they were running official software. So never downgrade to ROMs based on older firmware sources than the one you have on your phone!
