Downgrading XPERIA U - Android General

Hello everyone !
Recently I upgraded my Xperia U to Android version 4.04 ,but my phone has ever since been malfunctioning and misfiring , like making too many crashes (self-resets I mean) or applications performing pretty slow and so on so forth.
I've come to the conclusion that the good old Version 4.00 would perform best on my phone.
Been wondering if it's possible to downgrade it back to Version 4.Any help of any kind would be appreciated.
P.S : I'm totally new around here, so I hope I'm not misplaced !

Just flash an FTF to downgrade.

FRP LG G Flex2 Locked

Hi. I did CSE flash with v15e on H955. After it I have my phone locked. How can I bypass this lock? Please help me.
Can I downgrade to android 5.0? Is it solution?
And there's no option to launch dual window when I choose overview. And in accessibility\TalkBack there's no option to launch "Settings"
Okey, if someone have the same problem, solution is CSE Flash v10e.
I thought going from 5.1.1 back to 5.0.1 bricks your phone.
No, it didn't brick my phone. It was the only one solution for FRP lock

You know about knox i suppose? Since you unlock bootloader twrp root etc efuse is "blown" and no warranty
So there is no anyway to return 100% stock?

there is a way to return to stock but as per the others mentioned since s5 cmiiw this knox problem started and there is no way to remove the trigger in knox and you lose your warranty.

Samsung galaxy a8 (SM-A530F) - Downgrade

Hi everyone,
sorry for the bad English. I got a phone from my sister (original box), which she got at work, but she doesn't know gmail to log in. When she finished working, they gave her the phone. But even at work, they could not advise her. I tried turning on the phone, but another gmail account wants me to. I'm a beginner, but I was able to run android recovery and there is information that this is the A530FXXSCCTE1 Android 9. I tried to upload another original lower ROM via Odin, but Odin always reports an error. OEM is locked .... Don't you know if it is possible to fix this in any way? I like the phone, but I don't know how to do it myself
I've been trying it for 3 days and without success.
Thank you very much for your answer and have a nice day
David
Not possible.
