Hi everyone,
My phone (Redmi Note 10 5G China, camellia) was lost baseband a week ago for no reason. The phone lost signal when I saw, and can't read SIM card 1 hour later. After reboot, baseband version in setting turned to unknown. The MIUI version when this problem occurs is 13.0.9. I tried to flash MIUI to the version at the time of the problem and older version (13.0.3 and 13.0.8) to repair baseband followed with tutorial on internet but had no effect.
When I flashed MIUI 13.0.4 and try to startup, the phone turn to black screen after the Redmi logo appears about 10 secs later, and then nothing happens.
The same problem happened to this phone half year ago. At that time, there was magisk in the system and I think magisk destroyed system and tried to flash to repair the system. Finally, baseband was repaired by flash MIUI 13.0.4, but baseband will lose by reboot, so I flashed again, it was solved. But a month later the same problem happened again, but it only lasted a day, and the next day it repaired itself, in the meantime, I'm just using my phone as before. About a month later I upgraded to MIUI 13.0.9 and didn't occur any problem. At that time, as long as this fault occurred, flash MIUI 13.0.4 could always solve it.
Did the failure occur on the motherboard or just is a software problem like before? If there is no hardware problem, how to solve the problem completely?
Sure Is not a magisk problem . And i dont think is related to board, or a new flash dont solve. I think Baseband is related to kernel. Probably latest update have some bugs. Or more probably u have made a wrong flash procedure. If u put the sim on second slot have same issue?

Hello guys,
Short version:
My O4X suddenly lost signal and IMEI, look likes hardware problem. But when I reflash with V20A kdz, it works then after few restarts, It happens again.
Any help will be appreciated. Thanks in advance.
Detailed version:
- I was on CM11 nightly (20140923) for some time, it was smooth and no problem but then suddenly lost imei and signal.
- Tried to flash and wipe the latest nightly without luck
- decided to try the V20A kdz and it works again for few restarts (root and stuffs)
- Tried kdz without doing anything, just restart. After 3 restarts, lost IMEI again.
Thank you for your time and thank you in advance.
Also the friends here have similar problem but mine is still flashable... not sure for how long

I have your s problem and dont know what i will do. If you can. Please help me/
i have the same problem with my p880
I had the same problem...
In my case, as far as i can tell is hardware related.
The connection (imei and baseband) returns only if i use brute force, and start to press the phone very hard near the edges, near the the sim. .But they disappear if i turn off or reset the phone...

Is hard to take pictures because this is not a tutorial, i press different parts every time i lost my imei, until it works. What i do is pressing really hard (even bending a little the phone) everything above the battery, especially the sim card holder. Sometimes take 5, 6 , 7 attempts until the signal returns. When the phone turns on wait a little, because takes a few minutes until the signal returns.
I have kind of the same problem, but with slight differences: if I restart the phone, most times than not I get the signal back (at least for a few more hours) and using Zaiben's RC17 ROM it manages to get the signal back by itself after a while, no reboot needed. What I've found to be a "hack/solution" for this problem is to use the app Tasker to change network mode from 3G to 2G when the screen turns off. It appears than while in 2G this problem doesn't present itself...
@sergiohinniger apparently your brute-force method kinda works for me as well.
My phone started losing IMEI and baseband version after I replaced the audio jack and "small" PCB (the one with USB - now I'm back with original one). I then re-chcecked all connectors and coaxial cable, but the issue persists.
I think it works after few reboots with pressure on the back, so I believe that most likely it's caused by some bad cennectors. I have no idea though what to do with that Help, anyone?
It's true, with Zaiben or any stock roms the signal returns far more easily and sometimes resists the reboot. But now i have a new problem, the mac address, even when the signal returns, stay 00:00:00:00:00:00. I can only fix with a mac spoof app. This problem doesn't happen when i use custom roms, but the 3g signal is harder the return.
Some news, bad news
I have asked some repairers and here is their answer:
It's baseband file problem, if you have original Nandroid backup then it might help otherwise you can say bye bye to it

basically, the baseband/IMEI file is damaged due to flashing rom, if you dont have origianl file, there is noway to save it
Sorry for bring back a dead post, I think it's a good infomation for people
Need Help "LOST IMEI and Baseband Unkonwn"
I was using Euporia 5.0.1 on LG 4x
I received update notification and I downloaded Update.zip ( which included to 5.1)
By mistake i flashed the zip directly from CWM ( without Formatting any partition )
after restarting there was no IMEI
Following things I have tried
1) Trying to flash Original V20C KDZ. via LG Flash Tool. ( I think it checks for IMEI , and that's why stuck in between)
2) Use LG Software Update tool. ( also can't progress with IMEI)
3) Flashed Original V20c Flashable zip from CWM (But it didn't restored my IMEI)
4) Contacted LG Service Center, and They say You need to change whole Motherboard. ( I was Shocked to know that )
:crying:
If anybody went to same problem. and resolved .
Please Guide me.

A repairer told me that some rom might contain RIL or baseband bugs that accidentally **** up our IMEI partition/files, so if you have NANDroid backup then try to restore it
Hy guys,
I'm facing some issues with my Z3C. I bought it 2 weeks ago, unlocked bootloader, installed twrp, flashed CyanogenMod 12.1 Nightly on day 3. Updated CM twice with OTA since then.
My problem is that the "sim" card (GSM/LTE) is randomly not noticed by my phone, like if its removed. I checked the sim tray, everything is stable and well seated, the sim is also OK, never had an issue with it. I just have it in my pocket or on the desk, pick it up to do something and there is already a No SIM icon on the status bar, and "Emergency calls only" If I lock the phone. Only a restart solves it.
I could not find any noticeable trigger which would lead me to the source of the problem. Sometimes its OK for 2 days sometimes it happens 2 times a day. The really frustrating part is that when the sim "disconnects" the phone starts to heat up significantly. I usually only notice it because my phone is burning my pocket. Also it looses around 20% battery before I notice it. After the restart everything is fine, the phone cools down.
Went to the Cyanogen forums for some possible solution for the problem, they suggested that I should try to update my baseband to the latest version, and if that still doesn't help, do a full wipe / clean install of CM nightly. I tried downloading the latest firmware using FlashTool and XperiFirm, creating an ftf, and flashing only AMSS_FSG, AMSS_FS1, AMSS_FS2 included into the flash ( I only wan't to flash the baseband ?!?).
My question would be: Anyone else had this problem and managed to fix it somehow? If not, anyone could please help me with a small guide how to ONLY update the baseband of my Z3C (D 5803) running CM 12.1 nightly on twrp recovery?
When I tried the flash above, my baseband version did not change. Currently I'm on "8974-AAAAANAZQ-00005-40" Baseband version, and I would like to move to the latest most stable one.
Thanks for the help in advance!
If it were my Z3c, I would flash back to stock completely and then reflash with Cyanogen. This is a device on which you have the freedom to do that, and that gets the job done safely. Backup your CM install, and then flash everything.
Hi everyone,
I have a big issue with the xiaomi.eu Miui 12 20.7.2 and other after this...
After install in my phone (Mi 8) I dont have access sim card. Is like that I dont have any sim card. And no wifi to.
I've done first a dirty install and after a clean install but the problem continued.
After I was rollback to the 20.6.18 version where all works fine! if I upgrade again the problem still the same...
What can I do?
Thanks
Same issue
Hi, I have the same issue, in my case that issue started once I installed Miui 12 20.07.16. I tried installing other ROMs without fix this problem, I will wait until they deliver a new version waiting they solve this problem.
Which TWRP did you use to flash the rom?
I don't think it is a software problem if you have the following symptoms, No WiFi but Bluetooth, no service but detect SIM card, random reboots out of nowhere or when trying to turn on WiFi, unknown baseband and it gets hot, apparently it is a processor SoC solder problem
Hello guys.

Did the issue fix itself?
I am encountering the same issue and looking to know if it is a phone thing or an update issue.
I factory reset the phone but the issue is still occurring.
I tried downgrading to 12.5.3 but it didn't work. Seems like roll back is prohibited at my phone.
The issue stopped occurring for approx 9 days and yesterday without doing anything it started reoccuring and has not stopped since.
The issue keeps reoccurring even in safe mode.
I am totally confused. I don't know what to do
The same issue with mine also after updating to 12.5.4. The phone can't be used while every 2-3 minutes disconnects from network. Any ideas?
After updating to MIUI 13, I randomly have freezing issue (when scrolling tiktok, playing game, watching youtube, etc.) which sometimes fixes if I wait and the system shows notification of "The *app* stopped working" or something, and many other times I can only force reboot the phone (by holding the power botton until it reboots).
The issue never occured on MIUI 12, only on MIUI 13 from the first version untill now. So overtime I downgrade the ROM or change it to other variants such as global version (the issue also occurs in other country's variants of MIUI 13), hoping that the bug is fixed everytime there is a newer version of MIUI 13 of Indonesia but it's never been fixed.
I report many times through the feedback and service but they only suggest to keep the RAM and memory managed, and to charge the phone in time, which don't solve the issue since I have plenty of internal memory space available and use the phone the same when I'm on MIUI 12 (also how the hell do I charge it in time?!).
Does anyone have this issue as well? And how do you fix it other than to downgrade or to change to custom ROMs? Is it better to wait till MIUI 14 comes out than to downgrade it again? Sorry for my bad English.
i have the same issue though, I'm still hoping an update for this kinda issue because it's really annoying. I'm not sure for install custom rom will fix it, or it does.
I ever thought that downgrade is the only way to do, because when I use miui 12 I didn't get any of bugs and issues.

MIUI 13.0.8 just came out a few days ago for my region, but I won't upgrade it at least until MIUI 14 comes out.
Installing custom rom does fix it. I tried Pixel Experience once and never got the bug, but I didn't quite like the overall appereance so I decided to just downgrade it again to MIUI 12.5.5.
Yes. I have had this EXACT same issue, too. factory reset did not resolve. Redmi Note 9 Phone is all but useless now. Can use for a few minutes at a time, before it freezes. Miui 14 should be around the corner now, but I'm not hopeful.

MIUI 14 also does not resolve the issue for me, so downgrading is the only solution (not even MIUI 13 and 14 based custom rom fix it). But some people from RN10pro forum got it fixed after a few updates. Here are some suggestion I got from there:
1. Check if your SD card is dead, simply replace it or take it out.
2. Change your system to light mode.
3. Disable the memory extension.
Some people got it fixed after doing one of the above suggestions but not for me.
