Random network disconnection and can't search for network manually. HELP NEEDED.

I first experienced this bug after I installed superior os 25/10/2018 build. The bug was that the network signal keeps getting disconnected and reconnected automatically at random times, and I couldn't set the network manually. So i thought that it was a rom bug, and i went back to miui, but what i found is that bug was now also in MIUI , and i cant fix it. I tried flashing miui 10, latest version of 9 via twrp and also with mi-flash tool (fastboot) ,but the bug is there on every rom, i cant find a way to fix it.
I googled and found that someone else had the same problem in some other xiaomi device and there i noticed the term - "somehow RIL is getting stuck & re-initializing (restarting)" , <- maybe this is the problem .
Can anyone help me fix this RIL thingy please ? :crying:

Do you solve this problem?
i started having issue with my camera after 12.5.9 update my default miui camera app would close after clicking one photo although it was working in other camera like snapchat or fj camera. But few days after 12.5.10 update both front and back camera completely stopped working.
I unlocked my bootloader to downgrade the rom or flash custom rom as this seemed like a software issue . But after a week when i downgraded to my surprise the issue was still there which implies that the camera hardware has failed . So i dropped the idea of installing custom rom and instead went to service center, now they are replacing the motherboard as its hardware issue . I am gonna get back my phone today from service center so will update you guys accordingly .
Blog Link - This is the blog link which discusses about same problem even xiaomi has accepted the issue.
Its weird that software update can cause hardware bug but what i think is that with the update kernel setting might have been changed which can cause over voltage to camera module or something. Its my wild guess i don't have much idea about it . I would love to know it from experts out here .

I have checked CIT, but failed. Problems began after January update. What should I do now?
Do they work in safe mode?

Question Mic and sound issue on latest MIUI ROM

Hi everyone,
I have some issue with my device, I've installed the latest Fastboot MIUI ROM (V13.0.2.0.SKSMIXM) and I have issue with my microphone since that.
No way to make a call (the basic for a cellphone), I can't manage sound (it's always at full level).
Anyone else have the same issue ? Anyone have any solution ?
That's a very annoying issue for a phone that we canĀ“t call with it....
Thank in advance
Suggested downgrades
Fastboot MIUI ROM (V13.0.1.0.SKSMIXM or V12.5.***)
