Hi guys,
Recently my Pocophone f1 has started to reboot randomly, and sometimes freezes to the touch (although the rebooting is far more common). It reboots even when the phone is idle and there doesn't seem to be any trigger causing it.
I have tried flashing multiple roms including Pixel Experience 9.0 and xiaomi.eu but they all exhibit the same issues.
I have decided to return the phone back to complete stock with the global rom and have locked the bootloader with no improvements.
In TWRP the phone seems to behave normally and never reboots, but sometimes the touch screen freezes. Flashing roms always seem to go smoothly through TWRP and fastboot.
Does anyone have any idea as to what the problem could be? I'm assuming its a hardware problem but the fact that TWRP and fastboot seem to have no major issues is slightly puzzling. I will try to change the battery soon to see if that fixes the problem.

Same bro.Any solution?
Same here.
Hi, I encounter a problem with my Poco F1, for the past few days my Poco with stock MIUI suddenly cannot detect the SIM card. I tried swapping slot but it does not fix the problem. I tried flashing to an older version of MIUI (from MIUI 11 to MIUI 10), the SIM card starting to get detected and getting service but after few mins it get no service again. So after multiple times clearing the cache partition and flashing different version back and fourth, it still wont fixes the problem.
So i get an idea to use custom ROM mainly Lineage 17 and 16 and try to determine whether is a hardware issue or just Xiaomi MIUI problem. First I install Lineage 17 on my phone and the SIM cards work and even get service but... after one hour the phone starting to get no service again. So i try factory reset and all that, doesn't solve the problem either. So i try Lineage 16 again and same situation. The situation is definitely better than MIUI because MIUI will try to prevent me from connecting WIFI and for some weird reason i wont be able to turn WIFI on. This problem is solved in LOS 17 and 16 luckily.
tl;dr I try flashing and reinstall different version of MIUI and LOS 17 and 16 but still get no service.
I suspect something is holding back my phone to detect the service.
I'll attach the logcat for all and radio in other reply.
Please help me determine the problem, i have no idea how to fix this phone anymore. With the current pandemic and movement control order, I can't visit any Xiaomi service center. Please help and thank you. Sorry for the bad english.

Just few days after installing miui 12, got this problem. The phone is stuck on a boot loop. If I pattern unlock the phone, I get a toast saying "find device stopped unexpectedly". Unfortunately, I don't have a backup. :crying:
Is there any way to save my phone? or may be get a backup?
I too experienced the same bug, i went to the official service centre to fix the issue. They reflashed the os but the same issue kept arising again and again after a day or two, the service center guys had no clue what's going on. At last I decided to unlock the bootloader and flash a custom rom. Now am using RR without any issue.

yeah, I am also in the same track but I am unable to make MiFlash Unlock tool to recognize my phone in fastboot mode. Adb does recognize, Mi PC Suite recognizes it but says phone software has to be updated. (Using latest MIUI 12).
Any help is much appreciated. Thanks.

Use an Intel pc. Amd has issues with mi flash unlock too l. Run as admin. Turn off all anti virus/ firewall applications.
Having the exact same issue on my POCO F1, recently updated to MIUI 12. It was working pretty well up until 10 mins ago.
Battery went under 5% and the device went into ultra power saving mode, then restarted. Now every time I unlock the pattern, the toast pops up "Find my device..." and it goes into bootloop.
Now there isn't even a pop up, device immediately goes into bootloop.
bro, i just now facing this.. can you help me out
Well, MIUI 12 is not going good in poco F1.
If anyone who has not updated to MIUI 12, don't update the phone. Currently there are many bugs in the update
Long story short -
Some are unable to boot up the phone, some stuck in bootloop, some unable to use their passwords, some unable to set up new password, Second space not working, etc etc ...
I also updated to MIUI 12 and was unaware of the bugs.
But the device booted up and password (both fingerprint and face unlock) was working fine but I was unable to change it. Second space was working too. So I was happy that there is not much issue.
But then come the buggy part.
I started playing COD m after update and battery drained like hell 100 to 30 in 1.5 hour. I was shocked by this.
After charging I started to play again but this time (with battery issue) screen freezing happened and then happened at regular intervals. So the gaming experience on MIUI 12 was ruined.
Then I just find MIUI 9 for it and flashed it. (Ya, factory reset in this process too ?) But it is working fine now. Got fast charging module and custom thermal for gaming and it worked.
Currently no issue at all.
But I am still finding a custom kernel for poco F1 to overclock cpu and GPU (not able to find any till now).
Nearly every kernel is ment for MIUI 11 and 10 only. So I am digging deep for now to find a kernel for MIUI 9.
At last just one message - Don't update untill mi release a stable and bug free MIUI 12 version.
If MIUI 12 is working fine on your poco F1, either you are lucky or you have not encountered a bug till yet.
Without data loss, is this method come back to normal as before for poco f1 mobile?

If you don't want to loose your data, try flashing the rom using mi flash tool. But nothing can guarantee data security. You should back up your data regularly, waiting for a mishap or trusting on a single electronic device is just foolish, do make multiple copies of important data, if you want it to be secure.
I also have this problem. Updated my POCO F1 to miui 12 and it is in bootloop all the time. The bootloader is locked but I cannot unlock it now with no access to the device. How can I flash again a lower version?
If I don't mind losing the data how can I go back to previous version?
No brother, I encountered the same issues you mentioned. I stuck with MIUI logo loop after that I did a hard reset to mobile phone working condition.
hi
my friend own redmi note 9 pro
and have 'known' issue of random phone reboots during calls - like at least once a week during call his phone reboots itself
it was send to 'warranty' repair 3 times ! but they did not fixed anything.
so my question is
IS THERE ANY CHANCE THAT CUSTOM OS WILL SOLVE THIS ISSUE? lineageos for example?
or does anyone had this kind of issue with his one and custom os was the solution ?
thanks and regards !
It happened to me that my RN9P joyeuse restarted several times during a phone call or just while using it. The problem was fixed for me during the update (I think miui 12.5). It was probably a software bug when the phone tried to switch between LTE and another network which caused a restart. I am currently using the ForkLineageOS custom rom on android 12 and there are no reboot issues, previously i used lineageOS and pixel experience on android 11 and there were no problems either.

Can you review lineageOS for me?, is it good?, stable, and how to install it
not on rn9pro but on my redmi 9 everytime I try to call "*143#" my phone just magically reboots, and also the reboot persists too when I try to maxxed out the volume.
The WiFi suddenly turned off while I'm scrolling on TikTok. I kept turning it on in the settings but it just loads and then turn off. Then I try to turn on the bluetooth too but it also doesn't turn on (same with WiFi). Is this a hardware issue?
Im using
MIUI global 12.0.3
Android 10
Security Patch 2020-12-01
Pocophone F1 6gb/64gb
Could be an issue with the persist partition getting corrupted somehow. If bootloader is unlocked flashing the fastboot ROM might help.
So we hope this WiFi and Bluetooth not working on my Pocophone F1 guide could help resolve the issue you are facing with ease. If you have any questions regarding the guide or encounter issues while following it, do let us know by leaving a comment below.
