I flashed some ROMS n which corrupted the IMEI *#06# showed NULL no sim detection no wifi or bluetooth
i had twrp backup which had modemst1 restored it but no luck
i found many of them said flash color os n it will solve the problem, but due to low bandwidth i was not able to download the
so here is the solution flash the below file in fastboot n done i got my imei back
everything woks wifi bluetooth sim detection network all
unzip you'll get modemst.bin flash it
fastboot flash modemst1 modemst.bin
i was on cm12.1 -YOG4PAS1N0
hope it helps anyone who has imei null
Is this for all the OPO mobiles? Aren't these modemst files mobile specific? (I mean different for each OPO?)
Im facing the same issue now. I was on Calkulin's OPO rom CM12.1 based. I took a backup in TWRP and then I flashed CM13 nightlies. Everything is fine. But still I took a backup in perfectly working condition. Now due to high battery drain, I wanted to revert back to CM12.1 backup and restored it in TWRP. That's it. No IMEI, No mobile signal. Wifi, Bluetooth and NFC are working fine.
This is second time. I dont remember what I did first time, but I did not struggle this much. I guess I flashed CM12 rom and everything was normal. But now, I even tried Color OS but no luck.
I want to try your modemst, but worried if it is phone specific.

Normally you're supposed to flash your own modemst1 and modemst2 bin files that you backed up via terminal emulator commands. I'm assuming that's some random persons modem files that the OP flashed to get network back. Try this guide
http://forum.xda-developers.com/oneplus-one/help/fix-brickloop-audio-fx-fc-efs-corrupt-t2879061
Do the steps mentioned to try and retrieve IMEI. Only if all others solutions fail should you try the last two commands in the guide;
fastboot erase modemst1
fastboot erase modemst2
then flash a CM Nightly and see if it gets your phone back to working normally

Ok I have been an xda member for almost 8 years and this is my first thread , I have always found through search the answer to my problems with phones, but I cant for the life of me come up with anything on this. After ota upgrade to oxygenos 2.1.2 I lost lte (att/cricket) at first I thought it was imei related on att side, nope, then I tried reflashing modem manually through fastboot and somewhere in the procees went back and I had to reflash using hard bick method, after that I lost both imei and no signal , after a bunch of tinkering ive managed to get sim1 imei back but no signal!???? any ideas?
Same issue i got. Have sent a note to Support @ OnePlus. I have a Team Viewer session on coming sunday. Will let you know how it goes
hopefully it is software "fixable" and you we dont have to send it in to a repair center
Try to reflash full rom with firmware via fastboot.

Stock rom backups never really work. Sounds like the partition is corrupted. Send it back. They may charge you for a new board. Not sure on that though.

Only way I am aware of is with a jtag system. Which is around 1500 and you have to have the software for it. This is why it's always smart to make a back up of the efs folder.
Let alone on dual sim device. This is why Google doesn't officially support dual sim devices.

2 more findings.
1. I cant flash CM 13 not. the phone just bootloops.
2. Fingerprint is dead (Its behaving the same like it used to when CM 13 has the fingerprint apk but no drivers.)
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

Greetings!
I have been using Resurrection Remix for about a month now, but when the stock April patch came, I decided to return to stock firmware. I downloaded the most recent flash package from the official Xiaomi site and flashed it via MiFlash. When the phone booted up, I could see every wireless network, but when I chose to connect to any of them, the signal dropped a bit and it said "Connecting..." then immediately "Saved". After a few automatic try, it would just say "Disabled". The router settings are just fine, the phone could connect to it before I flashed stock rom. I also tried to download a bit older patch (9.5.4), which was neither good. After it I tried Nougat, but it still won't connect to the network. The hardware must be fine, since it was working an hour ago with Resurrection Remix. Could anyone help me out? Thank you in advance!
EDIT: Solved. The problem was with the persist partition, which is not flashed during the firmware flash process, so you have to flash it separately in TWRP. You'll have to download THIS FILE (persist.img), move it to /sdcard of your device, then boot to TWRP (you don't have to flash TWRP, only boot in it), tap on "Advanced" -> "Terminal", then type in the following: "dd if=/sdcard/persist.img of=/dev/block/mmcblk0p27". After it, reboot the phone into fastboot mode, and flash the firmware again. That's all.
Wifi works, but sim = 0

Just flash persist.img if you only have the WiFi-issue.
There's a somewhat complicated guide here in the forums as well. Just google "mi a1 imei fix xda".
I'll help you tomorrow if you cant fix it.

Here is solution: : How to restore IMEI permanently after using factory flash
I have the same problem with IMEI, the fix is permanent.
After the repair can be uploaded any rom, including Oreo .
I also twisted up my IMEI. When I tried to downgrade to 7.8.23 it was boot looping. I was trying to solve it for 6 straight hours. Eventually, somehow the phone became unable to boot into fastboot (or anything else) for no reason. (a random shutdown occured during fastboot mode while no command was given). I had to turn to the Xiaomi service, since nothing could be done with the phone. Guess I'll have to use my old nokia flip mobile for 2-3 weeks.

try flashing the latest void kernel.
I've been running LightROM (for some time) Pie, latest v20 with BL_G935FXXS8ETCO, CP_G935FXXS8ETCM and TWRP 3.3.1, and decided to change over to latest Lineage 16.0 Build 27.
Full wipe for LOS flash, but after boot-up and config found that it had no mobile signal and checking Settings | Software saw that IMEI is Unknown and Baseband version is empty/null.
Prior to LOS flash, I took a TWRP backup of Boot, Recovery, Baseband, and EFS. This was all I thought I needed for IMEI issues, and just restoring EFS would fix it. Unfortunately, not. Tried restoring all Boot, Recovery, Baseband, and EFS but still no IMEI.
I've been using wireless charging for a long time, and have found that my USB is not working (cleaned out socket, multiple cables, different PCs) but just cannot get it USB charging let alone data connection.
So, in order to get my IMEI back I believe I need to flash a stock ROM or COMBINATION. Both of which need ODIN and a working USB connection.
Thus, my query ... is there a STOCK ROM or COMBINATION that I can flash within TWRP to get my IMEI back?

Did you by chance did a backup of the full phone from twrp? If yes try to flash back in everything including the rom.
I always make a full backup on twrp after flashing a new custom rom and finish setting everything up. Just in case I did something wrong down the road I can just wipe everything and restore everything from the full backup. And I won't need to go through the hassle of setting the phone up.

Nope, you need odin and combination rom and ofcourse pc - per my best knowledge..
But if you have pc, but can't get odin/combination due to whatever reason.. follow this thread :

No, just Boot, Recovery, Baseband, and EFS. That's what I thought is all I'd need for any low-level recovery, since I was wiping and flashing anyway (a process I've done many times over the years). I thought the IMEI came from EFS anyway.
Thanks for thought.

Nope, you need odin and combination rom and ofcourse pc - per my best knowledge..
But if you have pc, but can't get odin/combination due to whatever reason.. follow this thread :

Thanks, unfortunately it appears that thread needs working USB though, which I don't have.
https://forum.xda-developers.com/note-4/general/fix-drk-dm-verity-factory-csc-serial-t3422965 looks interesting. Could that work for an S7e?

Yes follow this thread for imei repair using twrp. Should work
But be careful about the file paths..
S7 edge on oreo fimware path maybe different..
Also your phone must be in working condition..

Hasn't worked
Also found /efs/.nv_backup.bin[.md5] but using these didn't't help either.
Any other steps available?

Follow steps to letter, should fix your issue.. make sure you have su access in adb and you use the right file paths, don't know why a solution won't apply to your situation, it should as i think ..
