I am trying to update the firmware for my sim card because on later versions of lineage os it says sim card not found. I was told that builds from July and on would require this update. I'd like to make some sort of back up of my current firmware in case something goes wrong especially because I actually have a SM-900W8 converted to a SM-9005 with twrp. If anyone has any suggestions they would be very appreciated.
Sim Card has no firmware .
Or do you mean the Modem or EFS/ IMEI folder ??
Full backup via TWRP of phones firmware is the norm .
Awesome thanks

Hated stock rom so rooted using ioroot, flashed TWRP and installed G3 port ROM
Inserted SIM card but phone wouldn't detect
Reflashed baseband thinking that would help, no luck.
Decided to revert to stock
Flashed the 4.2.2 KDZ - I was dumb and didn't notice it was 4.2 not 4.4
Still no sim card detected
Flashed 4.4.2 KDZ
Still no SIM card detected.
The SIM itself is fine and I've tried another SIM with same problem.
The IMEI is showing up correct. Could I have killed the EFS partition when installing custom ROM? Would that mess with the SIM card detection?
Help please. Much appreciated
I am having the same issue. Can someone help us?

Check your phone's baseband, probably not the cause but yeah.
Try to clean the simcard
Try to clean the simcard tray
See or your phone might be simlocked or something like that.
maybe try to logcat and watch in the logs something to sim related text.
I can't give you ideas based on experience.
EDIT: I saw your other thread.
So you have flashed F400(G3) rom on a F320(G2)?
If so then my question to you is, is your wifi working? Cause flashing could may have caused some issues with the partition layout. I don't think there will be big differences/no differences but just to be sure.
Did you also tryed to flash back to stock and or flash baseband?
Was sim working before you flashed the rom? What rom did you flashed from the g3? Just so I could maybe inspect the updater-script if it isn't too large to see or it may got other partitions.

Did you find the solution bro
I'm having the same problem. I was on some old CM13.1 rom for LG G2 VS980 and releases prior to it, sim card was working without a problem. But only last night after updating from 10day old CM13.1 nightbly build with yesterday latest build, the sim card stopped working.
I tried method online which said to remove the card for one minutes before booting. Did it and didn't work.
What can I do now?

Nah, sent it back to supplier.
After trying to install few custom ROMS namely DR. Ketans and SimplRom I experience SIM removed error problem.
The flashing goes fine with full factory reset (only internal SD is not wiped), I enter the PIN when I'm asked for it. The SIM is unlock but when the phone registers on the network it gives SIM removed error and forces a reboot.
I also upgraded the bootloader and the modem to the latest versions BL_N910FXXU1BOD2 and CP_N910FXXU1BOC4 but the problem remains the same.
When I restore back to the original ROM (backed up by TWRP) everything works fine. If dirty flash custom ROM over it again there are no problems with the SIM card.
The only conclusion is that T-Mobile has some additional software installed.
The phone is SM-N910F bought from T-Mobile. It has T-Mobile branding on boot and shutdown.
Does anyone now anything about this ?
To update it with my own research.
Apparently the SIM card is lock to Macedonia region. MBM CSC. When installing custom ROM the CSC gets changed and the phone rejects the SIM.
In an effort to resolve this I've flashed DE DBT CSC ROM and the phone won't accept my SIM card.
Currently I'm downloading the original T-Mobile MKD firmware and I hope by restoring it that I will be able to use the phone again.
Also since I paid for the phone in full I intend to contact T-Mobile tomorrow and ask them to unlock my phone.
Will write what comes out of this. Don't want someone else to lose their nerves as I did today
Definitely the issue was in wrong CSC. I've downloaded the original firmware and everything worked again.
But I couldn't stay put and wanted to flash a custom ROM so I went with http://forum.xda-developers.com/note-4/snapdragon-dev/rom-bob4-devbase-multi-csc-safe-bloat-t3033881.
It's a great base ROM stripped of Knox and de-bloated. Most importantly it keeps your current CSC intact.
The procedure was:
Flash original firmware with Odin,
Root with CF-Auto root
Flash TWRP recovery with Odin
Reset data so that it completely goes stock because flashing the original firmware doesn't reset data
At this point I made full nandroid backup
Flash ALEXAND ROM
Uninstall additional bloatware
So far it's working fine.
I hope that this will help someone.
Hi there,
I think problem is intractable . It is a Samsung I9505 recognizing a sim and some not. I assumed it was the flex of the sim card , so buy him a new one giving the same result.
I 've just released by IMEI but that's not the problem. The phone will have 3 years old from Orange.
Where not directly detect and asks pin or anything just he says no sim inserted.
I have installed the latest free firmware PHE is SamMobile and nothing has changed.
Fixed network files and either Chimera .
Anyone have any idea that can happen?
Flash latest firmware and modem?
only the latest firmware one file in odin box pda
someone else to help me, not you think of anything else?
Is your phone unlocked to use other sim cards than Organe ones?
Is the sim not recognized at all or are you getting the message that the sim card was removed?

I maybe have flashed a different modem file with different ROM which lead to my baseband being unknown and due to that sim card not being detected. Can someone please upload their own nandroid backup so that i can get back to stock because I even went to the service centre and they are telling me that it is hardware issue and have to change the motherboard for 15k!! Just need the Nandroid backup of the stock rom of someone's phone who has an Indian Variant. Please Help

Hi ! Do you a have a efs.img backup ? Or any kind of IMEI/EFS/RADIO backup ?
I had the same problem I flashed the stock ROM and somehow I lost my IMEI info, I tried everything and I was even thinking about buying a z3x box but then I decided to do a very risky move , I completely deleted all the EFS related files/info and reflashed again but now I was not able to boot because I always sent me to recovery mode saying that :
"E:Failed To Mount /EFS (invalid argument )"
Then all I did was installing TWRP and rooted my SM-G935F and then I placed my efs.img backup on my internal SD CARD and went on recovery launched the terminal and wrote this :
dd if=/sdcard/efs.img of=/dev/block/platform/155a0000.ufs/by-name/EFS
Then I wrote reboot and it finally my phone was booting and I recovered my IMEI and was able to use my phone normally.
This only works if you have a backup of your EFS, and even if you do is risky , but I did it because I lost all hope and was accepting the fact that my phone would just become a useless wifi only device .
