Hello guys.
Recently, my phone's EFS files & IMEI got lost. I managed to "recover" my phone from its unusable state, but my phone refuses to detect the SIM.
My IMEI was 0, but I changed it back to my original IMEI. Yet my SIM still does not work.
The SIM itself works on another phone.
EDIT: It also seems that the SIM is indeed getting detected on my Mi A1, but no mobile network, and messages/calls do not reach me.
For the full story:
I flashed a MIUI 12 GSI (Android 9). Then, wanting to try out an A11 custom ROM, I flashed it, like I usually did.
It took extraordinarily long to load, so I force shut it down (this probably corrupted my EFS and stuff) and from then on no ROMs would work, and TWRP would give me a black screen, and a myriad of other problems
After 2 days of non-stop research, anxiety and magic I managed to "fix" my phone. The SIM was working at some point, but along the process it lost its IMEI, and even though I managed to restore it, the SIM does not get detected at all.
I would appreciate any help at all. Thanks for reading.

Let me preface this with some quick info about the phone. I bought it two years ago and it was SIM locked to Vodafone, Vodafone basically told the guy selling it to me it'd take 6 weeks to unlock so to get around this I went to a third party phone shop who told me they unlocked it but it wasn't until later I realised they had actually changed the IMEI of the device to get it to work. This was okay though, the phone worked fine and didn't give any real issues until two weeks ago.
Two weeks ago my N910F on Kyubi Note 5 Port ROM began telling me "not registered on network" (couldn't make calls, texts or use 3G), I went through standard troubleshooting with my carrier and it didn't appear to be on their end (the SIM worked in a Galaxy S 3 I have spare). I decided to update to 6.0.1 stock from Sammobile using Odin to see if it solved the issue, unfortunately it didn't. I was advised by something I found online to check if the IMEI was blacklisted on Swappa- turned out it was. I brought it back to the shop who had originally changed the IMEI. The guy in the shop told me it wasn't blacklisted but the reason for no service was because the device had a sum of "none" where the serial number should be when you dial *#06#.
He "fixed" the devices by changing the IMEI again and reverting to 4.4.4. He told me not to update it and everything would be fine. Obviously I wasn't too happy with being stuck on KitKat so he told me if I need to come back within 2 weeks after breaking it again that he'll fix it for free. Now the phone on 4.4.4 was giving a serial number and everything appeared fine.
I flashed 6.0.1 onto it and again the S/N became "none", but everything still more or less worked despite this. Since then I have Rooted it, flashed TWRP and installed Xposed. Once I installed Xposed problems began to arise again, the phone is reporting the SD card as corrupted repeatedly, everytime the phone turns on, once finished booting I will get a black screen with just a navigation bar and an empty battery icon (then after 2-3 mins it's fine), 3G wouldn't work at all, wifi passwords aren't being remembered, following boot I get the error message "process system is not responding would you like to close it".
Thankfully I made a backup in TWRP before putting Xposed on the device and restored the system to that this morning, which fixed the 3G issue but all of the other problems are still there (despite not having been there before Xposed was installed).
What should I try now? Should I go back to the guy again? Should I try revert to stock 4.4.4 or 5.1.1 through Odin? I'm really tempted to just cut my losses and sell it, but I love the phone so much. Any help is massively appreciated.

Changing the IMEI is illegal in most countries and therefore the discussion thereof is prohibited on XDA.

Hello,
I've bought a LG v20 h910 2 months ago. 1 Month after I rooted it succefully, i tried some roms, and I chose lineage os 14.1. But I have a major issue now: my signal data was very weak and i figured my IMEI was = 0, so I tried to flash the stock kdz. I've done it, and I've flashed stock h910r rom. But my problem is still here: I have no IMEI and my phone is acting very strange : when I boot it with lg v20 stock, my SIM card is recognized and I write the pin, but the screen stays the same, I can't access my services even if it is the right code... I also tried others rom like lineage os 15, but I can't even access the configuration menus, I get a green screen with ram dump, even with stock boot...
Is a total reset possible, or could someone give me a full TWRP recovery?
Unfortunately no, that's the problem ... I also tried xposed imei changer, but it didn't worked... Is my phone dead doctor?
Edit: I flashed another stock kdz, and the phone works fine, the only problem is the sim card (again); are my imei number and this issue linked?
Edit 2: I followed this https://forum.xda-developers.com/v20/how-to/stock-att-h910-stock-recovery-boot-image-t3528060 , and now i have lte and sim detected, I think I am going to stay on this stock rom in order not to have other problems. But my imei is still 0, is this a real issue?
After several hours and dozens of applications and commands (erase modemst, qualcomm toolkit, qpst,...), I still have no solutions ... I have access to data, but it's very weak and it is only on stock rom, on lineage os 15 I want to keep, it's worst... Is there nobody who already had a problem like this? And would sharing an EFS partition could be possible on 2 different phones?
I know, It is my fault if I don't have IMEI, but I can't return my phone, the warranty was only 1 month long, and I really need 4g because of my poor internet...
Ok, sorry for the multipost, but I've finally found the solution: I tried xposed imei changer on stock rom and lineage os 14.1, but it didn't worked. I tried on lineage os 15.1, and worked like a charm ! I hope all my issues are gone and may this post help !
Hi all long time user of the site but never been registered as never run into issues such as this below.
Recently family member took out sim of their locked three IE phone and tried to put another sim in into samsung j3 2016 sm-320FN model, one thing lead to another got message promoting for pin, even when original sim was put back in which never had pin lock on it and tried different pins which propably triggered some sort of lock on the phone but original sim works fine in any other unlocked phone.
When i took hold of phone i tried to root it and got hit with frp lock, eventually untied it from google account and managed to get lineage room onto it v14- no backup was made of original firmware my naive thinking on this part .
i used odin v3 with twrp 3 wiped cache david data and systems before hand. got it rooted with SUroot, and after then installed latest twrp to get other rooms onto phone.
Now strangest issue is that original sim works fine on any other unlocked phone but putting it into J3 i get hit with network unlock code PUK, at first tried support from three Ireland they thought it was sim blocked after numerous different codes it would return same message network unlock failed, eventually got hold of network unlock code, but entering it in lineage room OS it would say network unlock was successful but there would be no bars on sim, checking reception and signal it would show as none towers discovered and no signal received, following that every time phone is reboot it still promts for same code, figured it might caused issue with current room and downgraded to lineage v13 but still wouldnt see any reception the signal bar appears grey, final conclusion was maybe wrong unlock code was sent so requested another one which came back same as previous from mobile provider.And all repeats if entering code says unlock is successful but no mobile signal detected, tried 3 different roms and always keep getting greyd out signal icon and promt to enter puc unlock code.
In the process managed to wipe completely all rooms from the phone and did DBA backup restore via cmd and managed to get different room running on it RR-OS but same happens each time phone powered up inserting any sim including original network sim promts for code, after entering it, says successful and no bars or signal.
phone is only good to use for wifi browsing now, and im out of options to figure out whats the main reason also cant find original firmware.
Spent 2 days flashing rooms and unbricking phone but seems mobile signal and network unlock fails for unknown reasons to me. tried to list every step ive taken and software used.
If anyone has any idea whats causing this would appreciate any help, even thou phone is old by now but still enough for person that uses it.
Hi all,
I have a problem with my XC, i hope there's someone here who could help me out with this .
I get a SIM card error when i start the phone. After a while (5-10 mins) the error transforms into "No Service" as if the phone now detects the SIM card but has no service whatsoever.
Things i did to my phone prior to this:
- unlocked bootloader
- installed custom recovery
- root
- installed custom ROM
- drm fix
The phone did function properly for a few months actually after these operations without a SIM card error even once. But then i tried to install custom ROMs again (and i'm sure didn't flash ROMs not suited for XC) -actually tried to install "existenz" ROM but i did get a bootloop so i -once again- did the usual procedure with flashtool and flashed a firmware to set everything back to stock as close as possible. That was, when i started to get the SIM card errors. After several restarts (cold and warm) the phone sometimes recognized the SIM card and i could use the phone normally. But this was true only till the next restart, where i got the same SIM errors again.
Things i tried:
- flashed several different firmwares (official) with flashtool (wiping everything) - all the newest firmwares.
- *#*#72786#*#* in dialer to wipe carrier settings
- *#*#4636#*#* in dialer to go into phone settings and changing those settings randomly
- flashed another AOSP based custom ROM instead of stock sony
- wiping and formatting everything between the flashes of course
- cleaning and re-inserting SIM card (which i never took out before anyway)
But unfortunately nothing worked. Phone keeps to not recognizing the SIM card (which is working just fine in another phone). Everything else works just fine on the phone. The IMEI is displaying correct. I'm almost certain that the fault isn't hardware-based (i didn't drop the phone or exposed in water etc.) but software-based. Did i just managed to brick my phone by flashing something related to the modem which i'm not aware of?
I can't find any solutions on google, which help me, which is why i'm posting it here. Sorry for the long post.
Did anyone experience such an error and/or knows what else i could try to fix this? I hope for answers
Thanks in advance!
Anyone?
I've got the same problem.
I didn't unlock the bootloader or anything prior to getting the bug.
I wanted to downgrade to nougat, because aparently it helped someone in the forum below, but I didn't manage to do it.

Did you try nougat, when flashing different firmwares?
Your post makes me question if its worth it, trying to downgrade.
Try to remove sd card if you have one. then restart the phone and see if sim card is recognized.
I had the same problem and I think it was a hardware failure in the end.
I also tried almost all the things you were writing above. In my phone it started slowly. Sometimes the SIM was detected but after some time the connection was lost.
It happened some time after I installed a new battery.
But since there are no original batteries available for the device anymore and the new battery was even worse than the 5 year old original battery, I gave up investigating the SIM issue and don't use the phone any longer.
I bought a new (used) x compact because I still like the size and I saw some development was going on for this device.
In the end I cannot tell whether the SIM was not detected because I broke something while changing the battery or due to age of the phone but I think it was a "normal" failure.
I also read from others that they had the problem and the SIM was working for some time after I switched the battery before it stopped working.
Nevertheless. Good Luck to you. Maybe it is something different on your phone.
I got a replacement for my mi9t as my old one had a damaged screen, and moving my SIM card into the new phone is quite strange. On boot it won't see it, and if I pull it out and put the SIM back in, it is seen, but won't make calls or get data.
Things I've tried are a factory restore with fastboot (5 times), updating the device, downgrading the device, and checking if APN settings matched the old device. Any other suggestions?
EDIT: Resolved
I managed to brick the phone the day I got it. The TWRP restore destroyed my IMEI apparently, so I can't connect to cellular towers now. Oh well. It's a paperweight.
