after downgrad from A10 to Pie no Gyroscope and Compas function - Sony Xperia 1 Questions & Answers

Hi,
i had some issue's with Android 10 so i tried to downgrad back to Android 9...used Xperfirm to download 55.0.A.10.26 UA
but after flashing there was no Compas or Gyroscop function anymore....not even available at the service test menu (*#*#7378423#*#*)
so i flashed latest Android 10 version again and all is working well...any idea's how this can happen
or another source for the Android 9 (55.0.A.10.26) to download.?!
thx for any support :good:

Perhaps trying a different version of Pie?
By the way. does twrp work for you after downgrading?

newer flashed twrp
tried couple versions of Pie (EU, UA and play PL) not one brought back the sensor (gyroscope) back
updated OTA and with first update to Android 10 sensor started working normal....like a miracal.....Sony did something at the backround on our devices for sure....like deleting some function key's
so if u like to downgrad new devices u'll lose function's like u lose on rooting your device

Thanks! Good to know

i red some guides they said u need "OEM Unlock" to downgrade.!?

Use newflasher by munjeni to downgrade else there will be problem like you faced.

How can I downgrade my Android 8.0 to 7.0? (Mate 10 lite)

Hey,
Altough I bet there are hunderds of threads like this, I decided to create another one
So because I have my mate 10 lite around 2 years (a bit less), I would like to get an upgrade. Sadly I won't get Android Pie officially, so I'd like to install a custom ROM.
To do that I need an unlocked bootloader which dc-unlocker is only able to do below Android 8.0.
So I would have to downgrade my Android 8.0 (Btw, EMUI is also 8.0) to Nougat 7.0.
The method through HiSuite didn't worked since it just says "Newest Developer Version installed", but nothing with "Switch to other versions".
Also through Firmeware Finder (Playstore App) it doesn't show me the option "In-App Proxy", so I guess it doesn't work either with that.
Is there another way to do, if so I would really appreciate any help
Thanks in advance
My Mate 8 also keeps on Android 8.0, without any update to Android Pie officially.
If the official utility, HiSuite, which is developed by Huawei doesn't work, we maybe have no way to downgrade the system software on Mate 10 or Mate 8.

It all depends on your current build version. If I remember correctly the ability to use DC was patched in most custs in May or June. So if your security date is prior to May you can still use DC. If not you're out of luck. You can use testpoint to flash board software and then get unlock code through there, but it requires you to remove the back of your phone which will break IP rating and void warranty (If it's still under warranty)

Honor View 10 - Downgrade to Android 9.0 ?

Hello everyone.
Planning on installing OpenKirin ROM on my BKL-L09, i have to downgrade to EMUI 9.0.
Problem is HiSuite doesn't let me go lower than 9.1. I then wanna ask you guys if a downgrade on 9.0 was possible.
Will the 2018 security patch make it impossible ? Is there a way even to do it ?
I know forcing HiSuite to install 9.0 is a bad idea, because i tried installing 8.0 which bricked the device entirely. I had to buy a service to reflash the stock rom.
Bootloader is unlocked.
Have a nice day, guys. Take care of you.
@Soriahz Can you please post the procedure to downgrade from EMUI 10 to 9.1? I am unable to do so on my BKL-L09.

Simply plug the phone while being booted in Android to your PC. Launch HiSuite and go to Software update. Click then on the right part which is called "other versions". You will then have the 9.1.0 update available.

Mi A3 screen won't turn on after finishing a flash process

Hello,
I did flash my phone in fastboot mode to the official Android One ROM and after finishing, the screen doesn't turn on.
What can I do?
Thanks
You need to provide more information.
You need to at least state which android version you are flashing and which android version/ROM you are coming from.
To me it sounds like you have flashed android 10 on an android 11 ROM. This results in a hard brick due to anti rollback.
Please state the firmware version you tried to flash, the ROM/firmware you are currently using and the process in which you flashed it.
I was flashing from a custom ROM of MIUI 12 by xiaomi.eu to the lastest available of Android 10 in order to get back to Android One.
Thanks
Did you have Android 11 before installing MIUI (did you do the conversion to cc9e)?

There's your problem. There is anti rollback in this device so essentially you hard bricked it.
You can't go back to android 10 stock at all once android 11 is flashed.
The only way to recover is flash stock ROM through EDL mode which may require a Xiaomi authorised account or bring it to a service centre for repair
Then my phone is done... There is no use trying to fix it.
Thanks anyway!
Hello.
I'm bringing this up again as I have now more free time in Christmas. I've been charging the phone fot a whole day but nothing appears. I don't know if I need to send it to a repair store or something.

Why NFC works only in Android 11?

I downgraded to android 9 and noticed that it isn't working. I have downgraded multiple times but it used to work.
If I update my phone to android 11 latest then it works again but I don't want to upgrade to 11.
what might be the issue? How do i fix it staying on Android 9?
NFC in settings cannot be toggled!
Thank you
Hi, is NFC working on UK Customized Android 11 for 802so? how did you Flash it? I really want NfC back no matter the android version of it. thanks!
It is not working now.
If I flash any A11 Customized ROM it works.
