Downgrade to android 9 still possible? - Samsung Galaxy S10 Questions & Answers

Hello friends, is it possible to get my s10 back on android 9?
Thank you in advance for the help of a stupid question

I don't think so. It looks like you're on bootloader 7? I am on bootloader 3 (U.S. S10+ G975U) and I cannot downgrade to Android 9 anymore.

Yes bootloader is 7

No, you cannot. You could install a different firmware but with bootloader 7. No downgrade anymore. Samsung says its because safety reasons.

The tool didn't work on the beta either. I had to flash Android 9, unlock bootloader with the tool, and then update to Android 10.

Yes, I just flashed the RAW Android 9 file. I have WW version.

but this is so dumb... why don't they already have it updated. they knew the release was here.
Beta 9 was already the "full" stable update.
ugh. now i need to go back, unlock and then go to android 10.

you can also use the asus downgrader: https://www.asus.com/Phone/ROG-Phone-II/HelpDesk_BIOS/ and download Version Android 10 downgrade to P (WW) - Or use the one catered towards CN version if you have that.

Is it possible to downgrade to Android 8?

Hi guys,
Using Mate 10 (C185) on firmware 10.0.0.180.
Is there a way to downgrade it all the way back to Android 8, without unlocking bootloader or installing custom recovery?
Thanks for your response in advance.

Thanks, but are you sure that i can go from Android 10 to Android 8 with Hisuite?
Just from 10.0 till 9.0.0.246.
I managed to downgrade from 10.0.0.180 to 9.1.0.320.
But now, hisuite dosen't give option for rollback to older version anymore...
Any idea or guide that i can follow from here to Android 8?
madcapfrog said:
10.0.0.180-ról 9.1.0.320-ra sikerült leminősíteni.
De most már nem ad lehetőséget a régebbi verzió visszaállítására ...
Van valami ötlet vagy útmutató, amelyet innen követhetek az Android 8-ra?

Use an older hisuite version!
But unfortunately I was only able to upgrade to 8.1 as well.
I used last hisuite to downgrade from 10 to 8.0 in 3 times. Works on ALP-L29(C636)!

Possible to raise the Android version above 9 on Nokia 8 TA-1004 without root?

Hi everyone. i searched the forum but did not find any suitable information, i hope i did not miss anything.
I have a Nokia 8, Model: TA-1004 (Dual SIM), running the latest known stock update to me Android 9 00WW_5_15G_SP04.
I have some company SW on the phone which starts to make a fuzz about the to old Android version (9) so i have to either buy a new phone or update the current one. Problem is that my company does not allow any rooted devices. Is there any chance to update it to a newer version of Android without root?
Does anybody know? The phone is otherwise great and it would be a bugger having to buy a new one just because of this.
Best regards and thanks a bunch for any possible help here.
regards
You can put Android 12 Pixel Experience on it, default is unrooted. But ofcourse you need to unlock the bootloader.
Thanks for your reply. Now that sounds interesting. I will have to check how that is done. Have not done that before.
Have you got a link for that rom somewhere?
Regards
Basicly all is covered here: https://wiki.pixelexperience.org/devices/NB1/install/
Nokia Bootloader Unlock Took doesn't work anymore but you can still unlock using this guide: https://www.techmesto.com/guide-unlock-bootloader-nokia-android-phones/
After bootloader unlock you can install T-Virus, it includes PixelExperience Android 12, then just take OTA to latest version.
