[HELP] How to return MI A2 to factory system - Xiaomi Mi A2 / 6X Questions & Answers

Well, friends ... this is it.
I converted my Mi A2 to Mi 6x and everything was working fine. One day I decided to return my smartphone to the factory system, but unintentionally deleted all files within TWRP. Now I have the following dilemma:
I can get into TWRP and fastboot, but when trying to install any ROM by MI Flash (Jasmine_Spout or Wayne) the program says "Can not read from port COM *).
Can someone help me?
PS: Forgive me, I'm from Brazil and I'm using the translator to write this text.

Hi there, you can revert back to Mi A2 using Qfill or mi flash 2016 64 bit in edl mode, see this thread for details:

No, you have to flush only the 6x rums, and watch the arb Now that exists in Pixel Expiriencu!

1st time I converted to mi 6x, I was able to flash A2 ROM that I just needed to push a2 twrp then flash.
Since I got arb4, it becomes trouble in flashing mi a2. so, I am supposing it is the cause.
anyway, anyone has any idea or found a solution, please share.
thanks

Arb4 means no ways back as far as I know
ARB 4 has no solution!! (and i think will not have...)
I'm on this boat and the best solution (for me) is flashing the Havoc 2.5 for Mi 6x (wayne), the best ROM based on Android One
Use edl mode to flash back to stock. Edl wont judge you for being in arb or even when hard brick

Strange issue with mi a2

So i've got Mi a2 device and from the last week it has a brighter screen sections, around whole display (looks similar to the p20pro glue gate). So i decided to send it to the Amazon, but currently I am using the PixelOs ROM, so I need to flash it back to stock Rom, and then lock bootloader. The problem is, that I can't flash it via MI Flash (device error, or smth like that, all device tools doesn't work at all too), and when I wanted to just Flash it in TWRP I recognized that's support only .zip files and the Rom is in a diffrent format. Last time, I did ,,big back to the stock rom action" I found a website, with the commands, that allows you to flash it with GZ file, and Minimal ADB and Fastboot, but I just Can't find it now (Thanks Google), so I'm asking here: How can I back to the stock rom using Twrp only (or command prompt ofc).
Convert Back to A2
Download latest a2 stock rom.
Put phone to edl mode again (fastboot oem edl)
Flash stock rom via QFİLL with same method (Select .ddr and xml files from stock rom folder) and power up.
Done.
(If you have wifi camera or splash screen problems. Flash stockrom with miflash on fastboot (vol down + power ) again.)

That`s not true.
I didn`t try it, because there`s no reason for that, but this is how to put back from 6X to A2
To restore everything back to A2, do the same thing, just use the original stock with en.miui.com for A2 for flash ROMs. Flashing for the first time from EDL, then once again from the fastboot to restore the fastboot properly. After the first flash, you do not have a logo for fastboot, just a black screen. To put it all in its place, another flash is miflash but from fastboot.

EDIT: I`m sorry. I was think that You was convert your A2 to 6x, and You want to bring it back to A2.
You can try it. Since the anti-rollback still not activated (anti 2), you can just flash your device to Mi A2 with MiFlash. Use official stock ROM Mi A2 and put your device in EDL mode, then just flash it like usual.

Try a fastboot firmware. There may be bat file included to preserve data. If not, at least you can get your device working with a locked bl.

[HELP] Cant change Mi A2 partition

Hi everyone,
I have a problem with my Mi A2 but I don't know a lot about Android.
I changed my partition with TWRP and installed Android 9 with Mi Flash.
Now I can't boot TWRP because fastboot doesn't recognize my device and I don't know why.
My goal was to install Ubuntu Touch (which requires A9) but that didn't work and I don't want to to be stuck with an outdated version of stock Android.
Please help me with this it would mean a lot to me.
