[munjeni]

I don't know! I have xperia 10 non mark You tell me!

I was able to downgrade my Xperia 5 mark 2 (XQ-AS72 version) from android 11 (58.1.A.5.159) to android 10 (58.0.A.28.51, XQ-AS52 version) using Newflasher only with UNLOCKED bootloader.
Method with unlocking and relocking bootloader described here DOES NOT work
I tried three times always resulting in a message that firmware is corrupted and device cannot boot, turning off in 5 seconds bla-bla-bla.
After flashing XQ-AS52_Customized EEA_58.0.A.28.51 I relocked bootloader and everything works perfectly.

I can't tell for sure how it work since I don't owning phone with possibility to relock bootloader, but what I found is described and its close. So steps is: unlock, flash old rom, relock, right?

Newbie question.. I found some people excluded the .ta file before they do flashing. I'm curious, what .ta file is, exactly?

Is there any harm to include them when do flashing, like the 'persist' file, for example?

Thank you

Don't flash persist, reason why -> https://xdaforums.com/xperia-xz1-compact/help/android-attest-key-lost-bootloader-t3829945

flash all the rest of files including all ta files.

Hold down all buttons (volume up, volume down, power) until device fully shutdown, than connect usb cable while holding volume down. In the same time watch your PC device mannager, look for yellow triangle if you see them you have missing flash driver. I can suggest you run newflasher and confirm 'y' when it ask you to install gordon gate, install them, reboot your pc, try again

Thank you, I tried to install the driver according to your method, it will prompt me whether to uninstall, I uninstalled and restarted and installed again, the PC still cannot connect to the phone. There is a yellow triangle in the device manager: Unknow USB Device (Device Descriptor Request Failed)

Windows drivers mess? Try to install Sony PC Companion software and do "repair phone", it will install drivers automaticaly and repair windows mess with drivers. Also try diferent usb port one from back of the pc for example. Also try diferent usb cable it might be broken. Also check for dust inside phone usb port. If you installed gordon gate I see no reason why you see yellow triangle other than bad cable or usb port

You mean Xperia Companion? No, press and hold the volume- step in the "Xperia Software Repair" option, unable to proceed to the next step. I used all the USB ports on the laptop

Xperia companion, yes. Than drivers is not a problem definitelly. You have tried all usb ports so it looks like only problem is phone usb port defect or defect in cable, I have no other idea. What is a VID and PID in device mannager of the usb device which have yellow triangle? You sdhould go to friend and try his cable+pc to be sure, we can't gues

Hello, I tried flashing Android 9 stock ROM on my Xperia XZ2 Dual SIM H8266, and it ends in a bootloop then shows a message saying "Your device is corrupt and can't be trusted and will not boot Your device will be powered off in 5 seconds"
PS: I didn't downgrade, I had Oreo 8.1
