Hello everyone,
It is possible to downgrade to Android 8.1 from Android 9 on Samsung A9 ?
I updated it to version 9 and it is very confusing to use as design changes are looking really bad.
If i restore original samsung 8.1 version what program do you recommend for full data backup so i don't loose any data/applications/pictures on my phone ?
Thanks.
Apps are linked to google account, they can be re-downloaded. As for data from the applications you'd afaik need elevated permissions to access that data or a custom recovery. Pictures you should be able to easily back them up to your PC. Generally you can always downgrade but you may be nagged about updating. Also if you had a custom recovery and restored data to an older version, it may or may not cause issues.
I can't give you full insight because the last device I've used relating to samsung was their note/note pro, and the s6. I just thought I'd toss what I do know here.

Hello,
I'm a total n00b when it comes to this stuff, but when I bought the new Galaxy S8+ I managed to root it using guides on this forum and it's now running an old version of the software.
Some data:
Phone: SM-G955F
Android version: 7.0
Build number: NRD90M.G955FXXU1AQDD
I know this is kind of old (1 April 2017) but it took me so long to set up root, get Magisk masking the right apps and customize the phone as I want it, that I didn't dare update the software with anything newer in case things go wrong.
Now that Samsung will soon be releasing Alpha Oreo versions, I was thinking of maybe moving the android version forward to something newer.
My question is, how easy is it? Is it just a matter of flashing the new release via Odin?
And will I lose any of my configurations? Will I lose root? Is root even possible in Oreo??
If it's not too hard of a process I might try it, just looking for some enlightenment.
Thanks!
Once the official version releases check for the ROM you're using to update as well, or flash one that's been updated. Unless you take the OTA on stock it's going to require you to full wipe though. Even then I would full wipe, you're upgrading to an entirely new version of Android. Dirty flashing not recommended at all.
Hi,
Have recently updated to Android 11 via Stable android update and I am looking for any way to go back to Android 10 via any means necessary. Have already made backups, can not root and unlock bootloader.
Any help is appreciated.
Same!
Yeah. I want to downgrade to a10 too. Is there a way to do it with or without losing data?
You need to, search for the roll back zip on the oneplus Community site. No way to save data,
Hello. Yesterday i installed latest OTA Android version (TB-J606L_S320030_210923_ROW) and noticed that it is really slow and it has even more bloatware that i don't want. I don't need to root it (because of bloatware removal) as i also need to revert it to default state as it was before update.
1. It is possible to find which version i had before this upgrade?
2. How could i downgrade system to previous version (i think it was Android 10 but i'm not sure)
PS: I successfully downgraded/rooted some devices but as every brand has it's specific way to perform downgrade, i'm asking here. Any advice would help and i'm aware of dangers of downgrading/rooting devices (bricking). In any case, it would be awesome to also link unbricking guide for TB-J606L, just in case It's always better to have plan B.
Update: I found source of roms for my device but i can't recognize which versions are old Android 10 and which are the new Android 11.
Hi, the current rom version of my Samsung S8+ is Android 9.0 G935FXXUCDUD1 to previous version
( And. 7 or 8) how can I return.
I would leave on 9 as it isn't vulnerable to some the nasty rootkits that can prey on earlier versions.
If you're really considering a downgrade, then it might be worth trying a full factory reset first (after backing up your data), since any downgrade will result in a data wipe anyway.
is your phone unlock? if no. u never do it
Thanks for the replies. The device is OEM unlocked, but according to my research, reverting to old versions is blocked by the manufacturer. But I'm wondering if there is a stock rom of previous versions for repair.
hello. i get out from the beta, to many problems with apps at the phone.
how can i get back to the last firmware ??
I think that you can downgrade through Odin, but don't forget to backup your personal datas beforehand.
Easiest way is to connect the phone to SmartSwitch on PC. It offers donlwngrade and install latest official software. Be aware that downgrade wipes all data so backup is a must.
