Need qcn backup. Please I am desperated. - Xiaomi Mi 4C

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.

MI4C IMEI/Baseband unknown

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.

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.

[Completed] Nexus 6 No LTE with correct IMEI! "0" Imei and LTE!

Ok, Ladies and Gentleman I need some deep thought processing here for some help with a Motorola Nexus 6. In brief here is what the problem is, a while back when flashing Pure Nexus rom, I experienced a loss of my IMEI. I can restore my IMEI but if and when I do, I lose any 4g and LTE connectivity. The phone functions in 3g with data and phone etc... just slow as molasses but if I restore my IMEI to the one that doesn't show up my IMEI correctly I get back LTE/4g and all works fine also. I've tried going all the way back to the original firmware which was saved to computer and restoring it. Same thing, I have IMEI but no LTE/4g. restore bad efs and get LTE/4g back. I've tried going through all the factory firmware's and flashing by ADB and or TWRP and nothing firmware wise will allow me to restore the IMEI and have LTE/4g signal. If I restore the bad efs and get OOOOOOOO for IMEI when using the *#06# on any firmware version, I regain LTE/4g functioning! I am using Pure Nexus 7.1 now and can still see the 00000000 as a IMEI, if I restore my efs and get IMEI back showing correctly, no LTE/4g signal! My phone can only function as it should as long as the IMEI doesn't show correctly! I have tried just flashing base bands and other segments of any rom and still the problem persist! I have even tried restoring an EFS from another nexus 6 and still no help. It's not the sims because I've tried AT&T sims and Verizon sims from other phones and it does the same thing! I've tried flashing with a sims in the phone and without. Any ideas??? It's like somehow a correlating segment of a file is not being recognized when the correct IMEI is present, like some thing some where in the efs, IMEI, and radio are not taking to each other so to speak, unless it shows the zero's! Brain waves come on and help me out here!

Nvram formated
I have the same problem because I deleted the NVRAM and unfortunately I did not make a backup. then I try to fix the problem using Miracle box by untroducing imei 1 and 2. the network has been restored but there is always a conflict from time to time the network disappears. 4G does not work and when I use 3G the SIM 2 loses the network, the MEID and always 0000 ....

If you have rooted your phone, GhostPhone app is working perfect and keeps all numbers without need to restore them manually on every update or changed mobile network settings(the last oftendeletes IMEI on many MTK 6xxx phones). If no root access - use MauiMeta to flash them from PC, it is not hard for use from unexpirienced people.

Mi Note 10 IMEI lost and baseband repair, QCN backup causes recovery loop

I have a CC9 Pro Premium. Even if i can't fix my problem, hopefully this story will PREVENT people from messing with their IMEIs... I hope no one ever goes through what I just did
I'm obviously by no means encouraging changing IMEIs, even in certain 3rd world countries where it could be necessary!
So here's a detailed backstory: When you purchase a phone where I live, you need a valid passport in order to pay tax and register it's IMEI number, and if not you get cut off by your operator within a month.
I didn't have one, since it also takes about 4-8 months to process, and I couldn't even preform a request due to the corona virus situation.
So, being the ignorant idiot I am, I thought it would be a great idea to change it's IMEI number till I can register the original one, since a lot of people do this over here apparently, white market
I followed a tutorial I found online (And re-posted on XDA, so there's nothing really wrong with it), and here's what happened:
(Root, TWRP and Diag is OK in all steps)
I made a .qcn backup using QPST build 480, saved the original somewhere safe, edited the copy, wiped modemst1, modemst2 and fsg, then restored it
*phone reboots*
Everything's the same, and still getting reception, no change
Took another backup and saw it was the same, so I give up
The next day I try again, but this time is when the problems started... I take another QCN backup just to be sure, and it's slightly larger (Could be because I just inserted a 2nd SIM for the first time right before it), edit it, then wipe modemst1, modemst2, fsg and this time: "fsc" since I saw someone do it in another tutorial for the Mi Note 10
*phone reboots*
*boot animation*
*resets and goes to recovery*
I was shocked. I wipe the 4 partitions again and the phone boots normally, nothing has changed (apparently).
So I put my SIMs in and go watch a movie. Then I switch it on, only to see there's no reception!!!
I wipe the partitions, and restore the first original backup... boots to recovery again...
Wipe... Boots normally... restore the 2nd original one (slightly larger, both sims)... boots to recovery...
Then I just decide to miflash a fastboot rom, maybe that will get things back to normal!
So I wipe, flash rom... IMEI and Baseband now Unknown... Yikes...
I next find an xQCN backup online for the Mi Note 10 that only has a single IMEI in it, that belongs to the 2nd sim (SIM 1 550 only, QCN View, the 1st 550 missing)
Replace it with my original and reboot, IMEI 2 and baseband is back! But no reception, even after multiple reboots...
I wipe partitions again, IMEI 2 is still there... Interesting...
I continue trouble shooting, even: wiping the partitions, restoring the original backup, flashing fastboot rom... still boots to recovery (Mi Recovery of course), setting 755 permission for modem files...
------------------------------------------------
SUMMERY:
I need to find out why the original backup keeps booting to recovery!!! Also some information about "fsc" partition would be nice, since wiping that probably started the whole issue (Is it a backup for fsg?!)
Important things I discovered:
1) Wiping modemst1 and modemst2 at the same time is enough for the phone to boot
2) The reboot to recovery (Recovery loop?) with the original backups is caused on an OS level, because one time it took so long that I even saw the lockscreen for half a second before it rebooted (no SIMcard in the phone either)
3) After hours of dorking I found 2 other similar instances that could be related:

So far it only seems possible to restore sim 2, I contacted a professional IMEI dealer and this is what he said:
"IMEIs cannot be changed simply through a USB port on modern snapdragon SOCs. Only the secondary sim modem can be restored, because the primary sim is locked to the chipset. When tampered with, it goes into a lockdown state which means it can probably never be used again unless a breach is found"
I sold the phone and got a Nokia 9 Pureview, much more consistent but still has it's own issues

If it's related to the IMEI, multiple guides have already been made since I made this post. Just search for it on YouTube!
If not, could be a bad rom, bad recovery, incomplete unlock, etc.
Try a stable Orange Fox Recovery, that might fix it

Hi , same things happen to me.I have mi note 10 lite.
before the dealing to imei I take modemst1,modemst2,and fsg backup via dd codes.
and take qcn and xqcn backup via qpst.
And after that In fastboot commend I write
"fastboot erase modemst1"
"fastboot erase modemst2"
"fastboot erase fsg"
so my imei have gone.When I edit the qcn ( imei1 and imei2 both) and flash back to the phone. phone is going to recovery mode and nvdata is corrupted error happen.There is two possibility to the save to phone. First one you wipe-data in stock-recovery or again in fastboot mode you have to erase modemst1,modemst2,fsg.
So I erased again and open the phone.
This time I edited qcn file (only imei2,imei1 codes deleted in codes line and string) so my edited qcn only exist imei2 codes.
so I flashed back to phone and imei1 shows 0 and imei2 shows my original imei(I want to recover my original imei). and after that in the adb I flashed my stock modemst1,modemst2,fsg via dd codes and (also some secret codes and combination ) and after reboot my both imei show and start working.I dont know the reason but somehow my phone skip the security.Interesetingly .I guess phone security in the software not to hardware.
I want to check something so I tried 20 time to flash my stock backups via dd codes but it is only work 2 time whenever I tried the flash and after reboot my phone add ramdump(app 2 gb every time) files in the main stroage ( I search it,it is crash log). Interesting
Right now I search to skip security so I find some codes in build.prop
"ro.miui.restrict_imei=1" I think this one cause the problem to change imei so I try to disable it but I cant change to build.prop because in android 10 you can't mount system(rw) so cant change to build.prop.I think only solution is flashing edited system.new.dat file but I cant decompile system.dat.file so .
After Android 10 magisk root app just work in systemless way(this is not even a root not like the old time).You have root but you cant change anything with root access so in originally this is not root and it is sucks and bull****.
Do you know any rom tool for the edit system.new.dat file or how can I create new custom rom so if I success it I want to change both imei. I googled it but every tool is too old to use.
Regards..

Good morning, yes, I'm working on a brother in law's smartphone (tucana) and I notice same issue, can it be solved?
We also bought Hydra Dongle Qualcomm Tool and Software but I'm not able to fix the IMEIs on his Mi Note 10 (tucana)
Maybe you can help me (tucana)!

Hi , same things happen to me.I have mi note 10 lite.
before the dealing to imei I take modemst1,modemst2,and fsg backup via dd codes.
and take qcn and xqcn backup via qpst.
And after that In fastboot commend I write
"fastboot erase modemst1"
"fastboot erase modemst2"
"fastboot erase fsg"
so my imei have gone.When I edit the qcn ( imei1 and imei2 both) and flash back to the phone. phone is going to recovery mode and nvdata is corrupted error happen.There is two possibility to the save to phone. First one you wipe-data in stock-recovery or again in fastboot mode you have to erase modemst1,modemst2,fsg.
So I erased again and open the phone.
This time I edited qcn file (only imei2,imei1 codes deleted in codes line and string) so my edited qcn only exist imei2 codes.
so I flashed back to phone and imei1 shows 0 and imei2 shows my original imei(I want to recover my original imei). and after that in the adb I flashed my stock modemst1,modemst2,fsg via dd codes and (also some secret codes and combination ) and after reboot my both imei show and start working.I dont know the reason but somehow my phone skip the security.Interesetingly .I guess phone security in the software not to hardware.

I read all your whole post and I can suggest to try to use XiaoMiFlash.exe of 2019-12-06 (WARNING: option below must be CLEAN ALL to save your unlocked state of the Bootloader) for flashing back to Android 9 in Fastboot mode original flash (those of about 4GB) , after that you can try to edit the build.prop with some Apps that work with root / Magisk.
But please, 1st I really urgently need your 4 partitions backup (also the fsc), can you send to me?
TIA and best regards!

Thank you for posting your findings on the thread! I believe the solution for Mi Note 10 users could be flashing Android 9 and changing that build.prop line, we need someone to confirm this. I hope you discover a fix for your phone as well, please write a step by step guide if so. Good luck!

Question Asus Rog5 imei Null No network

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.
