My Mi5 lately has random moments where the mobile signal is randomly disappearing. The problem start occurring since last week on Lineage OS 14.1. I've look around and found that this caused by incorrect step during ROM flashing or wrong firmware version when flashing.
So i tried clean flash another ROM today (Syberia) using 8.10.18 dev firmware (from the Syberia thread), and the problem persisted, I still get that random mobile network missing. Is there any way to fix this?

Yoh guys,
I will tell my problem short and quick:
I was using the Vanir Custom Rom 4.4.2 with normal gapps and was updating it once a week.
One day my connection was gone (wasn't able to make any phone calls, sending sms and
using the mobile data). So I was looking for some information and figured out that Android
4.4.4 was released a few weeks ago. So I tought there was a complication between the
android version I was using and the gapps. So I did a factory, cache and dalvik cache reset,
flashed the new Vanir version and installed the right gapps. But the problem still occured.
What i've tried:
1. Different Sim Cards. Tried another sim for about 30 minutes, no problem there while
I was still using the Vanir rom.
2. Using different Roms with the old sim card, the A.I.C.P. rom for example but the problem
got even worse.
3. Yesterday I installed the Lego Rom with 4.4.4 and using slim gapps 4.4.3, the problem
seems fixed so far. It occured only once today.
4. Just in case to make sure, I tried the Beanstalk Rom with 4.4.4 and the correct gapps for.
Somehow I had better connection with this rom than with the Lego one.
I stick to the Lego Rom now but it runs way smoother than the Beanstalk for me. Also I like
the theme when the play store is black instead of white .
My question now is, did some1 had the same issues? Or even better if some1 has a
resolution for it.
Thx and Regards,
Haven't you clearly stated and figured out that the problem is with your sim card?
No m8,
I can't be sure of that :/ I just found this thread a few min ago:

Everybody's got different ril problems
During your trials you said that using a different sim card didn't give any problems for the time running.
Can't you check that out first since most carriers will change sim for no price?
After that you can try changing ril using flying_bear's tutorial
I have the same issue....I tried FluidRom Omnirom CM, the last Beanstalk...sometime the network doesn't work.
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.
Im writing this because my battery life got really bad, and please don't start saying it's a ROM, Google or some apps I've installed issue, because I got this problem with basically every rom, starting from stable, dev MIUI ti LOS15.1.
As you can see from the pictures I get "Mobile network standby drain" in every rom, (In MIUI is called Cell standby)
So i thought It was a firmware issue and I changed, reflashed It and formatted a lot or times but no luck.
So at this point I thought that was an Android way to tell me my battery is diying, but I don't really understand, I also got an android wearable device but this problem persisted even before I bought it.
I've also attached a bugreport
2h of screen are also good for what I got usually, other days I can reach the end of the day 20% with 1h and 30 of screen.
Seems like I solved in LOS15.1 by flashing the latest firmware from the latest dev package from xiaomi, replacing the files on the firmware flashable zip which some guy posted, but not updated it.

So, did it help? Please be specific what exactly did you do.
Set the principal SIM(The SIM that you use mobile data) to 4G Network mode and the secondary SIM to GSM or 2G mode.
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:

Which custom ROM are you using right now that causes the random reboots?
