Downgrade works as long as it the same binary version. In this case U2.
You won't have to unlock bootloader again since it's already unlocked. Flashing full stock won't change that.

tys0n was right. I tried to downgrade from october's update but, cause the U2 version of bootloader, it wasn't possible. So atm I've just re-flashed the last version of stock firmware and waiting for news...

Just a note: Once you have unlocked bootloader, although I have flashed original BL back again, a warning image is showed indicating that the bootloader is unlocked. So I've customized the stock rom as indicated in following thread

You tried to flash back to U1 firmware?
Yes, warning will be there as long as bootloader is unlocked. You can also check out my bootlogo thread for A40 in case you're intrested. TWRP is preferred though.

[QUOTE=ponces;80817585]For those of you who made the October's update: can anyone test if this version of TWRP I compiled based on October's update sources is working?

Hello ponces
If I am not mistaken, your version does not work. It boots to a blank page.

Flashing back to A405FNXXU2ASG1_A405FNOXM2ASG1 works. No need to retreat further

Hey all, I'm getting into a boot loop.. Help is appreciated.

Step:
1 Got twrp running
2 downloaded image from https://github.com/phhusson/treble_e...%28GSI%29-list
This is the image: "Official Android 10 Q" system-quack-arm64-ab-vanilla.img.xz
3 Then, since its XZ, i use zarchive to extract it to .img
4 Then I put it on an SD Card, I wipe entire phone in TWRP and install this image on "system" partition.
5 I install A40 MultiDisabler from zip.

Now i get into a boot loop.. Anyone can help? Thanks!

If yes and it didn't work, could you please try again but using this version instead.
