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.

As it looks like theres no way using a Developer unlocked Mobile to run Apps or now that Samsung have blocked the Interop Unlock - even when you restore.
Is it possible to download a Previous update and "update" the phone that way. An update that doesnt have the block and so it doesnt affect the data on the phone?
Thanks in Advance.
"Updating" to an older version is not possible, no. It might be possible to spoof the current version to an old one, if the phone is interop-unlocked, and then "upgrade" to a firmware release that's actually older than your current one... but even that might not actually work, if the updater checks the checksums of the "old" files. It wouldn't work with OS updates for sure; those contain differential (rather than canonical) patches.
Installing an old, stock ROM with the old firmware does work. However, while this is possible with Samsung gen1 phones, I don't believe anybody has found a way to do it with gen2 phones yet.
Finally, restoring a phone backup (as made by Zune when updating, or as made using the Easy Backup tool which just spoofs the update process), definitely does restore both your unlocks and your ability to unlock - that is, it restores the registry (where the unlocks are controlled from) and it restores the firmware (where the ability to unlock is implemented). If this didn't work for you, it's due to one of two things:
A) Your backup (more properly called a "restore point") was created at a time when your phone already had relocked and lost the ability to unlock.
A.1) You can use an older restore point, if you kept them (which I strongly recommend); just move it back to %LOCALAPPDATA%\Microsoft\Windows Phone Update.
A.2) Before you ask, no, you can't use somebody else's restore point; they have device-specific encryption that we haven't broken yet.
B) Your restore worked, but trying to interop-unlock again failed because you updated your Diagnostics app from the Marketplace.
B.1) You can undo this by first uninstalling Diagnostics from the app list, then re-installing it using the phone dialer.
The other option is to use the stock flash tool and just update to Mango from stock.
I have the files for the Samsung Focus v1.3
I can upload them, but if you use it on another device, or on v1.4 it might brick your phone.
Just say if wanted.
I have used it a number of times, because of screwing up my phone and it not being able to boot up, even after formatting.
You will just need to put the phone into download mode, and it takes about two minutes.
My device version is N750XXUCOB2 (4.4.2) and the firmware through which i want to update my device is N750XXUDOK5 (5.1.1)(Russian update), is flashing through odin possible. if possible does it require rooting. and should i backup my data???
flashing is possible i did it aswell back in the day with my note 2 phone (sold). always backup that the most important thing if you care about data.
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.
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,
Hey all!
I have an Xperia 5 II that I bought used and didn't know the previous owner changed the Firmware on me (Taiwan -> US). I haven't updated ever since! So I decided t do my research and am going to attempt to update the firmware with Xperifirm. My question is, do I have to keep erasing my data everytime I update the firmware? or can I just update it? I am planning to keep the US firmware and just update it.
When you say update it, do you mean Android 10 to 11? If you are changing the version of OS then I would say it’s important to wipe the phone and do a factory reset. The apps that were installed when it was Android 10 don't work too well under Android 11. Usually people get all huffy about having to wipe thier phone when they upgrade, but I see you have embraced it already.
If you’re not changing versions, just simple update, then you shouldn’t need to wipe, everything should work fine, keeping your data.
If possible choose an unbranded veriosn of firmware to flash, as it generally contains less bloatware.
