Hello.
I just flashed the latest Lineage Rom and i'm having a problem with signal strength, it's zero. I tried switching through 2g 3g and lte and no succes. Only thing that works is to shutdown-open the phone and the signal is ok for 10 minutes then it goes to zero. Should i try another clean install?
Usually the error is com.android.phone has stopped, when i try to switch networks i usually get this error.
Also the battery heats up but afaik its normal until the rom settles in.
[Solved]
1.install 12122016build(cyanogen) and and back up only boot from it.(via TWRP)
2.install the newest build(cyanogen) and restore boot from the TWRP backup you made
The error shouldn't appear when you try to change the network, I suggest you to do a clean install
I have the same problem... no one replied to me yet...do you have the SIM unlock screen on first boot? or you need to reboot once again after you install the rom?...

Change network by 2G, 3G or LTE? Did that, dosen't change anything, also i did a clean install again.
But at Network Operators it just says Searching... and dosen't find anything, it stays on Searching... for minutes.

On fresh and first time i open the phone it says that i don't have a SIM.
If i reboot it says the same.
If i close the phone and then open it, the phone reads the SIM for a few minutes and then it doesn't work.
Tried switching to Airplane Mode, switching 2g, 3g, lte, no succes.
You have the same problem in CM as well?
after installing the rom i dont have the sim unlock screen, on 2nd boot i have sim unlock screen, it says i have signal but calling doesnt work, data dont work, cannot search for networks too..and yeah after 10 minutes or so the signal drops out and i have no service
when i posted in the development thread because nobody replied in the Q&A thread i got s**t on that i should write to the Q&A thread and give logtcats too...
then i added the logcats and even posted in the Q&A thread again but no answer...

Did you tried an older build or CM?
i tried an older boot.img and it worked but i dont want to do compromises like that... it worked on cm13 but not on LOS14.1 , i want to use the rom as it is

Newest build Cyanogen or Lineage?
Why don't you just install the lasted version and extract the boot.img from the functionality one without doing all that fuss backuping and restoring?

Well, did not found a functional rom until now, im just downloading different versions, flash them and see which one works, backup boot.img from the one that works and extract it in latest version.
12122016cyanogenmod boot.img and latest CM13 not LOS13 works, i have tried that...
let it go and return to stock.Honestly when the source-code for harware is not open source , no custom rom will be ok on the long run, is just change . change and change..and seeing how easy it is to brick this device , in my oppinion is doesnt worth the trouble.

My brother who lives in dubai used his sim card in this phone but ever since i got the phone in Pakistan ive tried using my sim but i get no service.
My guess is it only works with 4g LTE but i cant try cuz where i live here's only 3g and 2g coverage.
So i started using it as a wifi tablet.
Dialed *#06# and it showed both imei numbers but ever si ce i updated to purenexus 7.1.2 rom it gives me the same service error but dialing *#06# gives nothing but two plain zeroes like in the screenshot. Can anyone please help me resolve this i would greatly appreciate any help regarding this.please help my phone is useless without a sim card.
Screenshots show how it detects the sim card perfectly and gets the number.
-searches for available networks but cant register on a network:crying:

Hello, yesterday i bought used samsung galaxy s7 edge dual, sm-g935fd. It was rooted, owner said root was done to flash a rom to let phone see two sims. Went back home, started to install apps, and saw that snapchat doesnt work with rooted phone, so turned superSU, chose full unroot, phone did restart but stuck on bootloop. All I saw, was csc:g935f0xx1bph1 and pda:G935FXXU1BPLB. Could't find matching pda and csc roms, so installed another, for g935f, and everything worked fine, except from network, it only says emergency calls only and no signal, but it finds that my sim is from tele2.
On other thread i saw that i can use home_csc for my csc code, and any other pda, bl, ap, tried that and odin failed to flash it, so now flashed netherlands stock rom that changed my AP:G935FXXU1DQEF CP:G935FXXU1DQD7 CSC:G935FPHN1DQD1 Model: SM-G935F/DS.
Can you guys help me to get my network signal working again? I think that matching software for my phone would fix it, but i cant find which one to flash, or is there anything else that could have caused that?
Thank you for your help.

Sounds like your EFS is corrupted...
*Encrypted File System (EFS) | The EFS refers to a folder called EFS which can store information like meid, imei, serial number, config, diag settings and radio settings, etc in an encrypted format at the file system level stores. So it is very neccessary for us to backup EFS before flashing ROMs.*

i dont think that they can help me. I am not really good in flashing, because english is not my native language so i dont know what kernel means, whats the difference between firmware and software, and even rom, but i think that i have wrong bl/ap/csc/pda or something like that. Found that F in sm g935fd means it is international, looks like i can flash any country unbranded stock rom, but somehow it wont work for me, and i cant believe i did that much damage just by clicking on unroot in superSU app..
Hello, I have a problem and I do not know how to solve it. On my Redmi 2TD dead immc memory, I ordered a new motherboard put it on, everything worked. I decided to restore a full archive made with TWRP - made with the old motherboard. Then I rebuilt my IMEI. Now I have sim card, but no signal and the settings are only 2G. It also sees satellites, but does not locate. Maybe I did not have to restore the system, just the data from the old motherboard ?
Has this problem solution ?
Sorry for my bad english
If you have problem with network signal it may have something to do with firmware/bootloader version. Try kitkat or lollipop. You can find on download section

Flash stock.
Reboot.
Wipe format type yes. (I do this 3-4 times to give it a proper clean)
Flash fulmics bootloader
Flash fulmics
Boot into system. Leave it for 10 mins to boot up.
Go to settings and software update.
Make sure you use magisk and not SU. Seems to work better and makes boot run.

7.12.7_7.1, after that, my movile bootloop every 30 secons more or less
Now, when i turn the mobile on, it tells me that the SIM is blocked, but I tried the SIM in another mobile and it works
A/B partition are there so if device is stuck in bootloop it should boot from dormant partition.
You have to flash stock firmware.
Try flashing the persist.img from every build that exists till now. If you manage to flash one of them the issue will be fixed. I've tested it myself.

Please just follow the guide here to get it fixed: https://forum.xda-developers.com/mi-a1/how-to/ota-official-fastboot-image-n2g47h-7-12-t3728929
As it includes all necessary scripts for proper flashing it is secure to use
In worst case, you can also use the appropriate included script to factory reset at the same time when flashing. If nothing else helps, that should do the trick for you

I tried flashing persist.img, and it works!!!
Now I have 2 differents problems.
When I start my mobile, the SIM Pin page shows the message SIM CARD IS LOCKED - NO SERVICE. My sim works in another mobile
When I pu my pin, I get the message "preparing sdcard - Solving errors"
Please just do a full clean flash as recommended by me earlier and your issue should be gone. At least if they are firmware or software related.
After that do a clean flash and that issue should be fixed.

Excuse me. What do you want to say with "do a clean flash"?
Follow the guide I linked for you above. You have to use the flash_all script. So please have a look and give it a try.

Shooting blindly here.
Have you tried another sim in your phone.
If another sim card works then have you tried changing your sim from carrier. It's easy.
Have you also tried a factory reset?
