Hello. I got the new update to Android 11 today and it made my Wifi so unstable its barely usable. I want to reinstall the old Android 10 on my Xperia 5 II. Is there a way to do that? I dont care if it wipes the phone.

Hello,
since getting my nexus 4 couple of days ago, i've been reading all I can about rooting and such.
I think I got the gist of it but there are still some questions that bug me.
1) When installing a custom ROM what exactly the procedure for updating it. Do I need to reflash each time an update is out or can I use some kind of OTA style update ?
2) If I have 4.2.1 on my phone now, can I put for example a 4.2 or even a 4.1 ROM ? Can I go lower than that or it is impossible to go lower than what the phone comes with from the factory, in my case 4.2
3) I think i'll probably go with Cyanogen but they don t have a release build for 4.2 yet and I see nightlyes are released almost daily. Is there a simple way to receive the updates without reflashing ?
4) Can I mix kernels and ROMs or should I check which custom kernel each ROM maker recommends ?
thanks.
Not sure if this really should be going to the noob friendly thread, but since it is a couple of questions covering various Android related issues, I figured that I will make it a separate thread after all.
1. Sometime updating an Android version would also end up updating the bootloader, at time rendering it impossible to downgrade again. Can this also happen in custom ROM (e.g. Lineage). I am asking this because I am thinking of custom ROM with newer Android version on my Galaxy S7, but may want to revert to a relatively old Android 7.0 after I am done testing.
2. Do file systems (the way application, application data are stored in the system and other information) etc. tend to stay the same as stock for a given Android version? For example between stock Android 7.1 and Lineage 14.1.
3. Same question as question 2., but between major Android versions (e.g. stock 7.1 and stock 8.0).
4. On rooted devices, can you usually update major version update without losing any data, and is it usually trouble free?
Feel free to skip reading this part, but for some background information, the reason I am asking all those questions is because one of the app I tried to restore via Titanium Backup and Swift Backup both failed. The application itself launches properly, but as soon as I restore the data, it would instantly crash and close. My guess is that this is probably caused by attempt to go from Android 6.0 to 11.0. Maybe it is the backup software or maybe something changed in the way files are stored, but whatever the reason, it just won't work.
So I am thinking that my best option is to try it to restore it on an Android 7.0 phone that I have (also on the way to be retired, and if it works, update to Android 8.0. Since Android 8.0 was the last officially released major version for that phone, and I was thinking that if it does work, perhaps I could alternatively go for an early Lineage ROM, then make gradual updates up to Android 11.0 and see if it helps the app remain unbroken. And then if it does work, perhaps I could then make a backup then restore it on the other new Android 11.0 phone that I have.
All in all, it is a silly amount of work to do just for one app.. but it is important to me, so I will exhaust every option that I can think of to find a solution.
Thanks!
As soon as I've updated my phone to Android 12, is there any way to roll back to Android 11? I'm talking about stock UI 4.0. Unfortunately, if you are on Android 12 - there's no easy way to re-install a copy of Android 11 stock ROM. Flashing via Odin doesn't go through. Some people say that you need to go to a Samsung Service Center. I can't believe it! I'm sure there must be a fix for that. Of course, it's possible to play around with really high possibility to permanently brick the phone. I'm talking about reformatting partitions and flashing a pit file...
If the bottled version is higher on Android 12, it probably is, then you can't downgrade. In the build number, I believe it's the 5th number from the right might want to check that it with Google. If the new firmware has a higher number there NO going back...

Yes, it's possible, and I've done it.

I confirm that I also downgraded from Android 12 / One UI 4.0 (January 1 patch) to Android 11 / One UI 3.1 (November 1 patch) without problems. There were several aspects of the new version that were bothering me a lot, now I'm happy both versions are binary 3, but it will cease to be in the following versions for sure...
Hi can you help me with guidelines to upgrade to android 12? I'm using Note 20 ultra n985f/ds. It was previously a Live demo unit but is now fully functional on android 10. My csc is OXM WWD... looking forward to your help
Also I'd like to know which is better, should I just change my csc so I can receive the push for update via OTA or just follow a guideline for flashing with Odin, thanks in advance
hey guys, this is my first post and I’ve got a question.
Just yesterday I found my old tablet from when I was 12 years old, a Samsung galaxy tab 2 7.0 (the 8GB WiFi version, to be precise). I was kinda excited to find it, but then all that excitement went after I booted the device for the first time in 10 years. (yep, there was a reason I stopped using it). Android 4.2 jellybean was half corrupt on that tab. It boots ok, but system ui crashes and reloads itself when I unlock the device, and opening the gallery app just restarts the device. I want to reflash android 4.2 on the device to fix all the problems (I want the original android 4.2 OEM image, not cyanogenmod or an unofficial image), and also I might want to create a backup rom in case I want some old pictures or apps from the corrupt jellybean) Can someone provide a step by step guide on how to
1. root the device
2. make a backup
3. reflash the image (also send a link to the original android 4.2 WIFI rom
some extra info
Model number: gt-p3113
Build number: P3113UEUCMK3
All help will be appreciated
Update is the way you should take... Use SD card, the easiest way to update your old tab.. Google for the update file put it on SD card and start recovery, than take update option.
I delayed updating my phone for over a year, I ve had it for 2.5 years and now got a new one and going to sell it, so need to update it. But its stuck on MIUI 12.5.0 and will not update, it keeps downloading the same incremental update over and over again, it doesnt see any other updates even though its stuck on Android 10 and 12 is available. I ve updated the updater app, it makes no difference, I downloaded the latest ROM and put it on the root of the sdcard, the "downloaded ROM" folder and on several usb sticks, it will not see the update and nor does recovery see it. It driving me mad, any ideas ? Never had this on any Android device before.
