Hi everyone,
I messed a bit with my d802 and finally i used the lg support tool to get it back to stock, but now it can't read my sim card all of a sudden (no sim card inserted).
So the question is where are the sim card files, in the kernel or the rom or the baseband ? and how to get them back so it reads my sim card.
I'd be happy to bring you more info on the problem.
Thanks in advance.

I had the same problem, reflashing the 10B firmware then upgrading to the OTA 12A fixed the issue.

Did you sort this?
If not try this
Power OFF the phone. Remove the SIM card completely for at least 1 minute.
Re-insert the SIM card, Power ON.
If it works, I'll tell you why...

OK - good. This is a fairly common "problem" when making significant ROM changes - but doesn't always happen.
In basic terms...
When the phone is powered OFF, it isn't actually completely OFF. Some "parts" are still powered. The SIM card and its register are "parts" that remains powered and the register is sometimes overwritten when a ROM is flashed. This means when the new ROM boots, the SIM card and the register are different, hence no network as the phone assumes a fault.
The SIM card needs to be removed with the power off (NEVER with it on) so the phone detects a SIM swap and the register is refreshed.
TIP: Before flashing a new ROM - always remove the SIM card (with the Power OFF).

No SIM CARD after official lollipop stock rom update
Hi,
I have updated my LG G2 F320L (Korean Version by UPlus) on Lollipop successfully.
But now my SIM Card is not detecting. I am in Pakistan and dont know what to do now.
I tried to restart the phone with no sim and with sim and also flashed the same stock rom again but still no sim card.
I also tried to put the following codes i.e. for IMEI *#06# and for SIM Unlock menu 2945#*320# which didn't work too.
I also did factory reset many times with sim and without sim.
Tried to do rooting throguh Towelroot and Stumproot but no success.
Dear All, Please help as what might be the problem.

Unfortunately I don't have a solution yet, but I wanted to point out that I am in the same situation ATM. German lg g2 though. Please any new input would be highly appreciated.
Issue Resolved
Hi I took the phone to the android expert in mobile market in my area SADDAR AREA-RAWALPINDI CITY-PAKISTAN. Where he highlighted that the ROM, Baseband and Radios where not compatible as well as my phone had some EEPROM problem as well. So he hooked a small box like USB device and pushed the ROM into it via OTG along with the new stock ROM. Now my phone is working perfectly fine and I am more than happy and thankful to the expert. My current stock ROM is lollipop version: 5.0.1

I know this thread is hella old but, I stumbled upon this (after returning to the G2 temprorarliy - had it back in 2013/14) after restoring a stock LG ROM backup and it wasn't recognizing my SIM card. Anyways, this method worked for me to get the phone to recognize my SIM. Thanks for posting this.

i bought a t-mobile hd2, it is unlocked since it doesn't ask for a code, if i insert sim card it gets freeze every couple of minutes i tried to flash new rom change radio spl, nothing worked. only if i take the sim out it works like charm but the moment i put the sim in i freezes, i tried different sim same problem ? i did search cant solve my problem
If it's your SIM card, just take it into T-mobile, they'll replace it free & quick. But make sure you have the stock rom on it when you take it in or it will void any warranty.
If it's your microSD card try formatting it to your phone. If that doesn't work it's probably corrupt. Not sure if it's covered or not.
Sorry I couldn't be of much more help, but I'm sure one of these brilliant minds on here can help more.

It didn't ask for a code? so you aren't with T-mobile then I'm guessing..
You might wanna try a hard-reset, and if there's an SD card in there try taking it out.

I got to say, your panic is not going to help. First I want you to take a deep breath, and relax. Now, in order for us to help you. We need to have more information. More specifically, the following: Do you have roo. boot loader unlocked? What carrier are you using? What ROM and kernel you're using? Is your sim good? Are you using a micro sim? What radioband you're using? Is your sim card adapter slot damaged? Is your imei bad? Now you need to put this in a detailed explanation with what you have done with your device up until the point in where your phone stopped working.
stock room,one week old device, no root or nothing similar,the phone doesn't show imei number just blank window (*#06#)

If it's stock and all you did was do an OTA upgrade to 4.2.2 have you tried talking to your carrier? Being only a week old I would use their assistance to your advantage especially if you did not unlock/root the device. (not sure how you came across the sim card, if it was sold with the phone like it was with mine at T-Mobile, or if you just got the phone and then used a sim from the carrier).
but t mobile will send nexus to repair's for a month so do not want to be w/o my phone for so long.I'd like to solve it home...
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?

Hello,
i have got a S4 which has been rooted and flashed. It worked fine for a while but now every now and then i get a error message saying there is no sim card in it. When i reboot the phone it works normal again, without touching the sim or opening it.
I have cleaned sim card and contacts but that did not help.
Any ideas what else to try?
TIA

Hi ,
SIM card problems if they are not hardware related , they are usually caused by IMEI ( efs folder) or wrong modem if you have and efs folder backup , restore it.
What S4 you have , what rom do you have , what modem do you have??
When it fails to recognize the sim card check your IMEI dial *#06#
Hello,
i have tried everything i can think of without any success. It is a Samsung Gt-I9505.
The problem with checking IMEI when it does not recognize the SIM card is that i can't do anything but restart it. There is a error message with restart as the only option.
Now it is doing it as soon as it starts up. I never have to remove the SIM card so the phone recognizes it, just a simple restart without touching the SIM is enough.
I am on the last official Australian ROM. Baseband I9505XXUGNH6, Hernel 3.4.0-2309103 Build number KOT49H.I9505XXUGNH6
I have tried it with another SIM and same thing happens so it is not because of the SIM card.
Any ideas what else to try? I do not have any back ups of anything.

Hi mate,
Your case is not clear , it does not look like firmware but i would not discard that possibility , do you have stock or custom rom? try to reflash
Also there is a chance for what you tell me that the sim caddy may be defective

I am on official ROM, flashed over ODIN. You recommended to check the IMEI when this happens but i can't because the only option is to restart the phone.

When you have the no sim errors it does not allow you to dial *#06# ? why does the phone freeze ?

No, it does not freeze but a pop up shows with only one option "restart". I tried to touch the screen, home or return button but nothing works but touching the restart button.

I see, is strange if you said that whith a reboot works fine it make me think more in a hardware issue...maybe the sim caddy..
This phone is driving me crazy. The replacement SIM reader arrived today and i replaced it. Now it does not find any SIM, just getting NO SIM error as soon as it starts up. I tried putting back in the old reader but the same happens.
Anyone any idea what to do or just recycle the damn phone?
Come on guys there must be someone with an idea
hey guys,
I have just gotten my phone back from repair. It was getting the cracked lCD replaced.
So i went and put my SIM card into the SIM slot then i rebooted my phone, just to see a "No SIM" message which then proceeded to say "Insert SIM card". My wifi and everything is working and i can make emergency calls. I have previously had problems with my EFS folder and a corrupt IMEI but i fixed that issue and i don't believe that these two incidents are related whatsoever.
This is the thread with all of the information of my last problem. http://forum.xda-developers.com/galaxy-s5/help/service-t2898890
To try and solve this new problem, i have done the following:
1. Taken the sim card out and restarted phone and entered the sim card back in numerous times in various different sequences.
2. Done a full factory reset, reflashed a new rom, modem and bootloader.
3. Restored the EFS folder.
4. Tried a different SIM card.
This could be a hardware issue, but i feel as though it is software related, but i am no genius so i am open to any suggestions as to what it may be and how i may be able to fix it. If i am not able to fix it i will just send it back to the phone repairers and see what they can do to resolve the problem, but that would be the last thing i want to do.
thanks for any help.
not to worry. I have now solved the problem and everything is working perfectly.

i was on android 4.4.2 thouchwiz, i then upgraded to android 5, which also meant i had to upgrade the modem, which seemed to fix the problem. I then downgraded back down to android 4.4.2 touchwiz and that solved the problem.
so maybe you could try upgrading your modem or something? let me know if that works.

By modem do you mean radio?
It's an unrooted phone in my case, unfortunately.
the modem is a file or software i guess you could say in which controls the the signal on your phone.
hmmmm, im not sure what you could do then... im guessing you do not plan on rooting either?
