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!!!!
Hi, I can't find anything relevant on XDA for your device and issue.
You can try asking for help from this thread dedicated to your device ,

Good luck!
Thanks!
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
Alright so, first of all, I don't have any backups of it. And I recently flashed a ROM and after flashing, it couldn't read my simcard and my IMEI show INVALID. I've tried all kind of method to restore the IMEI. On Maui and SN write tool, it say that META Mode fail. Any kind of solutions will be greatly appreciate.

Downgrade your phone to the lowest supported android version and then try connecting in meta mode. That worked for twice on two devices.
Don't hesitate to hit thanks if i helped or replied.

Member you can take your device to your Carrier, to help in restoring IMEI. Anything else is frown upon, and most places are consider unlawful to change/tweak IMEI.
This will not be addressed via here or XDA on IMEI changing/restoring, Again, take your device to your phone Carrier for help.
Thread Closed.
Can someone give me a general idea of how to restore a lost Sprint baseband? I have a working phone the same model as the broken one, with root access, DIAG and MSL. I have tried modifying and restoring the QCL, and copying the partitions of the working phone, but nothing works. I can restore the IMEI and MEID numbers, but it won't recognize the SIM card and DFS
shows much missing information. I tried copying the NV files but that doesn't work either.
The phone is an unusual model. I have seen guides to restoring specific phones but I need something more general.
Please help
so, the problem is that you have lost it.
you can use z3x without box version to recover imei { your original } and patch certificate to get baseband and sim working.
if you need video tutorial search on youtube. thanks.

Thanks, dude. But as far as I can tell, z3x without box is only for Samsung devices.
can you please tell me your phone model and processor.
because if it it MTK then fix is very easy through engineering mode.
if it is qualcomm then fix might be complicated
if its samsung or lg then fix is z3x without box.
i am also learning, so pardon me if i asked any silly things,

It's a Sonim with a Qualcomm 8909 chip. But listen, I'm not exactly a newbie. Please don't give me simplistic answers. I believe what I've been working on is generally the way to go, I just need to figure out which part to do in what order
I make a software by QFIL - after that imei null
I Have The Box with IMEI but I don't Know how to restore It ??
there any solution to fix the network?
You need to hex edit your IMEI into your QCN file and flash it back to the device. Also from QFIL.

There are a lot of guides on XDA and elsewhere for the steps. However you need to first secure a working QCN file if you don't have a backup of your own and know the IMEIs in that file, so you can locate and overwrite with your own IMEI. Without that, you won't get far... I don't have a QCN file for this device on hand, maybe someone else here does and an share with you...

Is there a solution to unlock bootloader always Error11003
@Andrologic
Hey! I have been long trying to recover my nulled IMEI on ROG5. Every single tutorial I can find asks for a qcn file along with hex editor to input your box IMEIs. All follows up on my end until I use Qfil to restore a changed qcn file. It only writes till 2% and then phone goes into ramdump screen which means there's some kind of IMEI write protection on device or something like that. Because all other IMEI writing methods fail the phone to same RAM Dump screen. Desperate for some help.
Also there seems to be a problem getting diag mode to work on all stock ROMS. The only way diag mode works is by using ENG factory firmware on my ROG 5 which enables diag mode by default. The Asus_volte_su_fixed apk provided by @twistedumbrella Also doesn't enable diag mode on ROG5.

The fix was to allow it to see your root, nothing more.

This is not based on my own experience - but it looks like you may have access to write the IMEIs to this device via one of the ASUS Key partitions - in which case you may (or may not) be able to bypass writing QCN altogether.
I forgot the name of the guy who posted it, I believe it was under a CN>WW conversion guide - try to look it up and give it a try...

The Imei part was mentioned in the very last part of thhis guide:
Repair ROG Phone 5 ZS673KS through edl firmware, no need to unlock Bootloader to modify COUNTRY CN to WW
These materials can only be used for ROG Phone 5_ZS673KS, and ROG Phone 5S_ZS676KS cannot be used. ROG Phone 5S ZS676KS Please see...
forum.xda-developers.com
Someone tried that for a seperate reason and apparently it changed their IMEI:

Now, When I change the asuskey4 file, My IMEI do appear in the bootloader screen but when phone starts, it goes into a boot loop which stays even if I reflash the ENG firmware or stock firmware and ending in RAM dump screen.
Erasing the modemst1,modemst2 and fsg partitions from the phone does allow to get out of the bootloop. But shows Null Imei in the phone, while showing the IMEI in the bootloader screen.
So, apparently if I cannot restore the qcn file, There's no other way.
But Restoring QCN in ENG factoey firmware using QFIL or QPST only goes till 2% and then fails and phone goes to RAM Dump screen. Which apparently means that the phone has somekind of NV data write or IMEI write protection.
Writing QCN via Qfil goes till 2% then phone turns off and then status goes this 164% after which it shows that:
2022-05-05 08:53:19.685 Subscription ID:1 EFS File:/sd/mru001_ext_Subscription01, Function:NV_Tool_WriteNVsToMobile, Event:3 164%
2022-05-05 08:53:19.686 Done uploading the QCN file: C:\Users\mhrs_\Downloads\Compressed\GenericIMEI\patched.qcn, Sync EFS
2022-05-05 08:53:19.687 Done EFS Sync
2022-05-05 08:53:20.689 Reset Phone
2022-05-05 08:53:24.207 Restore QCN Fail:Restore QCN FailError in QTA.Phone.ModeControl :Error in setting phone mode to MODE_OFFLINE_D_F
2022-05-05 08:53:24.208 Finish Restore QCN
Attached is the log file from Qfil.
After this, phones goes into RamDump screen and when I hard reboot the phone, I can see IMEI changed from Null to 0 but still not my original IMEI :/
using qpst to restore only goes till 4% after which phone gets stuck in Ramdump screen.
Please help me to solve the network problem

Hi, Guys. I have the same problem since few days... Hope we will find a solution soon.
You cannot use others's qcn file to restore your imei. The imei store in fsg, modemst1, modemst2 also in your qcn file. If you use others qcn then they don't match each other, you'll failed to restore. The key: you need to empty the partition of fsg, modemst1, modemst2 in oder to restore other qcn file, but the system is read only so you cant do anything.
