Hi guys!
Yesterday my firmware update went terribly wrong and now I have a device that states that imei and baseband are unknown, so I my both sim-cards don't work.
I've tried several types of IMEI restoration, but none of them worked.
Unfortunately I don't have any backup for nvram. So, my guess is that there is a problem with EFS partition on the phone.
In QPST NV RF Manager I see my real IMEI from the box, so I guess it is still present, but my baseband doesn't work. Can you please suggest any help on recovering the baseband? Or if it is possible share with me modem backup or nvram backup without IMEI (I've seen on this forum that one guy with Samsung S3 had a kind of the same problem and he was given a working nvram backup without IMEI (IMEI was 0/00)) I can write my IMEI then, if baseband works again. Will appreciate any help.
Send it back. Only the oem is legally able to mess with the IMEI.

Well... I have managed to make it work again and my original IMEI is back. The only thing I had to do is to restore a working NVRAM backup (from another device) via QPST. So, it wasn't that hard. Much simpler than sending it back to China.

If you restored the file from another device then it won't have the right IMEI.

It HAS right IMEI, I checked it with the original box. No need to put up an argument about it. Both devices (mine and the one which was backupped and restored from) are working fine, bot have ORIGINAL IMEI numbers and no errors considering networks or MI accounts. So, actually I have no idea what you are trying to tell me.

I'm not making an argument. I'm trying to figure out how a number which is supposed to be hard coded into the file is then restored by restoring the files from a different device.
As these devices are not sold in the states learning as much as possible is a good thing.
Glad you got it working.

Okay, sorry. I will try to make it a bit clearer=) This device is not sold in Russia either (officially at least), so the only way to get it is to buy from aliexpress or ebay or anything else. In that case the buyer doesn't get any guarantee or official support. So if the device is broken and can't be restored it turns into a garbage. I believe that in the US the situation with that kind of devices is almost the same.
Now, if You are not familiar with QPST it is a software package for qualcomm based devices which can make backup/restore of some non-firmware software from the device (like IMEI, ESN, Baseband, LTE Channels etc). As for IMEI number, basically, as You've said it is hard coded into device so it is pretty hard to get it changed or fully deleted. Here we come to my case of unknown Baseband and IMEI. Though via phone settings I could see: "Unknown", my IMEI didn't change and was stored in the device. The "error" or smth like that happened after the factory reset and my guess is that the file structure of NVRAM was changed. So, backup of NVRAM taken from the working device didn't actually have IMEI or ESN in it, but it has the right file structure without any errors. That is what happened, the file structure was restored without changing any factory numbers.
If you have any questions, feel free to ask

It is almost the same with a few exceptions. One being that their devices are banned from all people that work for the government, sometimes they get stopped at customs due to copyright issues and with the latest news about them coming loaded with malware, most won't buy them.
That makes sense in a way. Not sure why a factory reset would mess up that part of the device as it shouldn't touch it.
Thanks for the info.

I don't know either, but it was an unforgettable experience and a lesson to do backups of everything.

Hi! Have you tried flashing China developer rom with Miflash?
Second option: Connect to your PC and run QPST according to one of the manuals (in order for your phone to show up as a COM), run RF NV Manager and look up your line 550 NV_IMEI if it is filled with numbers that are the same as on your box (check HEX above them and numbers should resemble yours from box but written in opposite direction, eg: on the box it is XXXX69XXXXX in the QPST it will be 96). So, if your IMEI is at its place than all you need is a working device from someone to make a backup. Backup must be made in newer versions of QPST in *.xqcn format and than restored to your phone with checked box "allow ESN mismatch"

There is a thread in official forum where one guy shares qcn backup. There is also an instruction to restore IMEI and baseband. But It doesn't help for me. Network still unavailable.
I have a Cricket branded galaxy s6 on the Cricket network and I was having some issues with the fingerprint reader which led to an eventual factory reset after trying many other things and of course I forgot to turn off reactivation lock beforehand. When booting back up I realized my Samsung account wouldn't sync up and I realized what I had done and after trying numerous things to fix that problem it led to me flashing the firmware for my phone and of course I didn't make a copy of the efs folder. So now my phone cannot connect to any network because the IMEI number is showing as unknown and so is the sim card status. So my question is... Is there anything I can do now to regain network connectivity?
If you are rooted you may restore nv_data.bak and nv_core.bak, that may get your IMEI back, if not, you can purchase a new and clean CERT file to get a new authentic IMEI back.
Would the phone have to have been rooted before deleting the IMEI number? I still have the original IMEI number written down as well
So I have 2 phones (both S7e), but one lost its IMEI / having "can't mount /efs" problem. This phone unluckily doesn't have a back up of its own EFS / IMEI digitally, but it still has the phone sticker that has its associated IMEI. Now, my plan was to TWRP restore a backup from the working phone to the unusable one so that I can fix the EFS problem and right after, "edit" the IMEI number to what it's supposed to according to the sticker left on the phone.
My questions are:
1) is this possible?
2) if so, can someone help me find out the proper steps/tools to help me change the IMEI on the 2nd phone with the temporarily duplicated IMEI
3) any tips on making sure I don't have both phones running and get blacklisted for having 2 phones with the same IMEI on i was thinking just to leave both phones on airplane mode or at the very least, turn off the first phone until I get the second phone working

Hello there, I got a Pixel 3 from one of my friends recently, after some days i reset the phone and suddenly SIM stopped working, when i checked the IMEI no. of my phone it was "004001520220002" this. But my original IMEI before reset was 99001200********. Now i had no idea what just happened with the IMEI. that new IMEI is blacklisted & hence i cant use the network on this, so i tried to recover my IMEI by using root method. After messing around with my device for a couple of days, i was successfully able to root the device and install Xposed Framework in order to change the IMEI no. I have changed my IMEI no back to its original but network is still no where to be seen in my phone. *#06# will tell me the old good IMEI but i am still unable to get signals on my phone. What should i do now ????? I am not an expert with the ROMs or modifying the OS. PLZZ HELP ME GETTING MY PHONE SIGNALS BAKC PLZZZZZ
How did you able to recover your imei, i'm going through the same thing, please share your procedure bro.
