[Completed] [Q] Xiaomi Mi2s - No cell signal after IMEI restore. - XDA Assist

Hi.
I have a Xiaomi Mi2S that doesn't connect to any cell networks.
I'm using CyanogenMod 11 nightlies, and after an update the phone lost its IMEI number. I had taken a backup of the NVRAM using EFS Professional, but when I looked for it the files where 0 bytes in length (probably a hard disk problem on my computer)
After trying a lot of stuff (installing stock MIUI, putting the phone in diag mode and installing a bunch of drivers), I managed to restore the IMEI number, but the phone still can't connect to the network.
I have tried a SIM from another company and it doesn't work. And my SIM works correctly in other phones, so I think that is not a SIM problem.
I don't know what to do... I tried flashing different ROMS, tried flashing a new baseband radio, but I can't get it to work! Is the phone lost???
Can anyone help me? I would appreciate it very much!!!!

Thank you for your help! I have posted in the thread you provided... let's hope that I can find a solution for this. I don't want the Android version of an iPod

I've never heard of this before and it seems extreme that you could lose IMEI number just by flashing a custom ROM. What method did you use?
I would have assumed fastboot flashing stock firmware should solve this.

Hi Sorry for late reply but I lost internet connection on Saturday morning.
When I have been doing some stuff in CWM recovery, had system and data partition mounted.
Then done rm -R * in root dir.
At this point I thought that my current dir is tmp.
After this I lost wifi and IMEI.
I manage to sort out wifi but not IMEI code.
Do you know how to fix this?
Since that I have been re-flashing stock rom and CWM rom but none of them help.
Chris
anyone can help to recover IMEI ?
Thanks
Changing/manually setting the IMEI is illegal afaik. And afaik assisting someone with that is also forbidden here on xda. We used to have a similar problem on the phone I came from, and there was a app which let you backup/restore your IMEI. You need to have a backup in order to restore it so this won't really help you...
This is what I'm talking about: http://forum.xda-developers.com/showthread.php?t=1591997
Edit.: There actually seems to be a way to manually set it but I'm not sure if it is device-specific.

You can find your Imei on the back of the phone.
If you google android 4.4 set imei you should find something from technostall which might help you
Good luck
Yes, it's on the battery.

I haven't.
I tried to sole this issues re-flashing with different roms, but after several operations it bricked.
It's totally dead, not charging, in linux I can't see device connected, so i think that is dead.
I bought new one.
Good luck with this problem.

I solved the problem, place to charge the phone, let him take some of the load and flash the original ROM, after that flash CM11, and run perfectmente, I think at first it was because I had done without the SIM, the second time you make with the SIM sunset ...

Yes It Does for most of the devices given you should know the proper method.
Mtk is different. It's not the same thing.
Any news?
Also I think the problem is that the imei is on the phone just not on the OS? (obviously, but...)
Maybe when we all reflashed to the original stock (and countless other stocks) they just didn't have the proper folder to access in order to identify what imei they're assigned?
Because every single time I've tried to manually rewrite the imei to it all the methods I've used are futile. Even the ones specially tailored to the Moto G's hardware SnapDragon - Qualcomm...
restore IMEI by Motorola service?
Same problem for me. I am really interested in some experience about restoring IMEI.
Motorola support phorum owner replied that Motorola service can recover IMEI (not covered by any kind of warranty of course).
I have tried to reflash factory ROM with and without inserted SIM card, but unfortunately no difference.
I have seen looking for solution, that for some people Android system sees IMEI=0, but the IME is still untouched using fastboot mode and "fastboot getvar" CLI command
For me it's empty using the "getvar" command as well.
The official service center in Germany told me that they mustn't repair selfmade imei problems :S
Lost IMEI
You could all try this new method claimed to be working but as I have not lost my IMEI I can't say, please report back if it works for you?

[Completed] [Q] LG F180(Optimus G)

I tried to install a custom ROM in the device but soon after it's boot I realized the network is not working, I tried to recover my stock ROM by CWM and all the old things came back. But the network is still not working, when I tried to search manually for Network Operators, then some other operators come in search but my network operator is not listed in them. I tired to search too much but useless. Please can anyone help me with it..
My IMEI is present and the phone shows it.
Hi there,

[Completed] [Q] Sim problems

Okay, so I recently bought a Nubia z7 max, and it came fine working, sim card worked in lte, all the bells and whistles, the version was a multilang version of the 1.64 official software, so i used the official update tool provided by to update to a 5.0 android version of their software so it would repartition my internal memory in a way that CM12 would work, it worked. All was fine and dandy until I saw a friends Nexus 5 able to dual boot(using MultiRom app from play-store) i was so jealous of him that i copied his build.prop to my phone in an attempt to make my phone think it was a nexus 5. My idiotic attempt got my phone in a boot-loop, this resulted in me flashing a 3.09 version of the nubia software on it then TWRP and finally restoring from my CM12 backup using TWRP. But i have a problem neither sim slots seem to work, i already checked and the sim card works(by putting it into another phone), and no sim works on mine. I would really appreciate it if someone could help me recover my precious phone. Thank you in advance.
Hi, thank you for using XDA Assist. Yeah, never flash or copy system files from a different device than you have. You most likely need to flash the stock firmware on your device and start over to get the sim to work again. The best place to ask how to do this is in your device specific forum. See here, http://forum.xda-developers.com/zte-z7/help and also this, http://forum.xda-developers.com/zte-z7

Need qcn backup. Please I am desperated.

Hello, I was installing a rom xiaomi.eu to my new mi4c as it came with a ROM 77 loaded with a lot of bloatware.The phone bricked while installing it and couldn't even start in fastboot mode. Luckily with a tutorial I could recover. The problem is that the IMEI got erased. And the phone had no signal and couldn't detect SIM.
I a tutorial in order to repair it with the QUALCOMM QPST TOOL the problem comes when trying to read the xiaomi with the RF Manager NV only has 4 NV files, not even the IMEI or anything.
Creating IMEI I could get the phone to read SIM, and to show IMEI when typing *#06#. But no signal.
Therefore the only solution I can think of and that saves my phone is that if someone is kind enough to make a .qcn backup of his Mi4c and share with me to restore my Mi4c (obviously would put my IMEI to it so no worries) so the phone can work normally again with signal and so...Thanks a lot, I need your help.
