Well, I have a device called "Tectoy ON 5029Y", the same as "Alcatel 3L 2020" (White Label), I'm trying to install a GSI on it, but I lose the IMEI and Baseband every time I unlock the bootloader, but if I block they come back, what am i doing wrong? I've done a lot of research on this device and there is little useful information.
I've already started GSI's, but they also have the same problem.

It will restore your IMEI, if it relocks your bootloader, you can unlock it again. Even flashing the newest version of your firmware should restore your IMEI and probably won't lock the bootloader in the process.

I've done this procedure before, about 4 times, the baseband and IMEI are never restored, only when I lock the bootloader. Also, until today I didn't have the stock of this smartphone, I used the Alcatel MU to restore it.
edit:
before I had restored after having installed the GSI, the bootloader did not come back locked, this time it came back! Then I unlocked it again and the IMEI disappeared again.

I don't think that restoring / changing IMEI is done this way.
OP is recommended to use Maui Meta Tool to repair the IMEI.

If you don't have EFS backup the only thing I know you can do is flashing stock ROM. That is what has been sorting it out for me. I think I've managed doing it once with ROM which was based on stock but I think that is very hard to happen in practice.

AFAIK on MTK devices an EFS partition / directory doesn't exist, but an NV ( NVRAM ) partition / directory.
BTW: A Stock ROM - the ROM compiled by OEM especially for each of its device models - never includes a device's IMEI. If it would be so then all phones of such a device series would have the same IMEI - which would be a complete nonsense.

I don't think I can fix the IMEI without a baseband.
Try to factory reset! When i lost IMEI on ZTE blade X3 its too helpful than i reset when this situation happen. and try to lock BootLoader again. and try to back to original ROM. +Turn off cell network and eject SIM card again and Turn on cell network after than you put SIM card again

I've already done that, the baseband and imei always disappear, when I lock the bootloader they come back. I don't know if this has to do with "Security boot MTK" or "AVB 2.0", I rooted and installed vbmeta, still the same problem remains.
@MrJosh18 Its maybe SIM problem.
Or ROM problem totally. MTK processors too vurneable to any BootLoader actions. Its maybe problems of Android telephony System apps.

well I don't know what else to do, I can root, install GSI and then I'll do a twrp port, but I really don't know how to solve these obstacles.
BTW: it's not just on my device, other people have tested it too
ROOT hmmmm
I think what solves for this problem are.
Maybe BootLoader break SIM totally. Wait

Use this CLI tool to back up (Read option) your NVRAM, NVdata and NVCFG prior to unlock it (you can back up any existent partition you want), after that you can use this tool even to unlock it and either, for sake of curiosity or for future reference, see if it produces a different result (i.e. not erasing IMEI). https://github.com/bkerler/mtkclient
Also, you're right, you need to firstly fix the baseband null issue to can fix IMEI. What Droidriven suggested was flashing your stock ROM after to unlock bootloader, a ROM from other device even if it is from a similar or from a rebranded device won't work/make the same that the firmware for your exact model, I know, probably is not available anywhere, but this is a fact.

The baseband is back, but still no IMEI

Hi guys,
I factory reset my s7 recently and when trying to root it again I lost my imei. Luckily I was able to restore using my old twrp backup which brought my imei back.
I restored the whole system, although I actually just wanted to use the imei partition.
So I guess I have two questions here, the first being: in theory, could I have just rooted the new factory reset device (with the imei missing) and restore the efs partition from twrp only? Would that work? Or, even more convenient, would there have been any way to write the efs partition directly to restore the imei (using dd or something similar?).
It would be cool if the latter version would work because in that case I wouldn't have had to restore my backup.
And another thing: is there a way to backup the imei only? Or can I restore an efs partitions made from my lineagOs system with twrp on any ROM (e.g. stock) and get the imei back?
Greetings deM
Can't tell for sure if you can just dd your way through, but I know for sure you can tamper with the imei without restoring or flashing the whole firmware, tho! using a paid tool/dongle, the z3x got many features and repairing/changing imei is one of them, if it can directly change the imei without flashing anything then you probably could do it too, I would also mention this process requires root and adb, but I don't have quite the idea about the commands or steps needed (especially for dual sim) as that tool I mentioned does the thing for me!

Okay thanks for the input. Using this tool is of course legit, I'm just curious if it could be achieved only by using a shell. Because in theory we have access to the filesystem if we're rooted so I figured we might be able to just to this using dd or something.

I noticed I didn't give you an answer for your question about restoring the EFS backup, and yes it works, you can even copy it from a phone to another, sometimes it works across different android versions too but that I didn't test myself.
In the shop I work in, we rarely get Samsung phones that have IMEI issues, but Mediatek and most cheap chinese phones, Yes, whenever there is an issue with IMEI or cellular network, I erase the existing NVRAM and flash a new one, and most of the time that solves it, for IMEI I use another Jtag called CM2 (chinese miracle 2) but it doesn't support the newer Mediatek chips with fully locked bootloaders, some clients won't go as far as unlocking the bootloader cause of the warranty and what not. Besides the CM2, rooting and using the engineering mode, you can push the new IMEI easily, with Samsung you can do that with root as well, but its way harder and doesn't work on new Android Versions!
Back to the Z3x and the S7, I've done some research, and from what I learned it accesses the EFS partition or something, with root ofcourse, it reads some specific sectors that contains the IMEI and network informations, then using zTool, which I don't know if its part of Z3x or some other software, to modify that information and basically allow to the network to be fully functional.
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.

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?

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!

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.

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!
There have been a lot of reports by those attempting to convert from CN to WW that they missed a step and wiped their IMEI.
Somehow, the same users have no box or stickers that tell them their old IMEI. Write down your IMEI before you flash anything.
Settings -> System -> About phone -> Status -> IMEI information

However, after flashing the WW firmware, I lost my IMEI. Shows as zero in settings. No signals etc also. Tried flashing the raw firmware from the tutorial again but to no avail. Forgot to backup my persist and modemst etc files. So, is there a way I can have my IMEI back. I tried tons of online tutorials to restore IMEI via QCN. Also I was lucky to get the stock QCN from another ROG 5 of a friend. Followed this tutorial for it:

It all goes as planned except for the last part where during qcn restore, It goes till like 3% and then phone auto reboots and shows a RAM DUMP screen from which I have to Force reboot and start. After reboot, The IMEI's still are 0. Any help would be much appreciated. I can see that there are many other people in the forum too having the same nulled IMEI ROGs. So, any halp as to restore them would be highly appreciated.

This thread was warning you to record the IMEI BEFORE you start flashing. After it's wiped out, you will need one of the threads on how to restore it. I don't have the phone anymore, but you can't simply flash someone else's IMEI. You need to restore yours.

do you think if you downgrade android 11 to android 10 will the imei come back?
unfortunately it wont allow me to flash any older firmware only the latest one
You should try with this method https://forum.xda-developers.com/t/...oader-usb-vcom-and-cycling-rebooting.4322581/ the general procedure might suit for all MediaTek variants, I didn't check completely the thread, you should interchange some files for/from your model.
Probably, it requires at least the OEM unlock toggle to be switched.
Be warned that I didn´t try it on a Samsung Mediatek device because I had the Exynos/Qualcomm A10/20/30/50/70 variants, not the MediaTek, but with most of MediaTek Realme, Xiaomi, it works.
You can add also this tool to the job https://github.com/bkerler/mtkclient.
Definitely some firmwares erase the baseband becoming to null, in the theory that IMEI is not really lost, then returning to a working baseband they also have to come back, but if they have gone then returning the baseband only, it only will return the ability to make calls.

Yes Imei/Baseband works again downgrading to android 10 o the BUF9 FW
Hello guys! I recently bought LMV600AM(AT&T) from eBay and inserted wrong network unlock code. So the phone said that "this phone is permanently locked..." and network's dead!!!
Anyone knows how to fix it??
I tried lots of things, such as change rom, crossflash to T-mobile firmware.. but nothing solves this problem.
So, here's my questions.
1) Can "Bootloader unlock" process solve this network lock problem?
2) I contact to someone who says that he can solve this problem. He says that he has "engineer firmware(or development firmware)" - I think this is LG developer's stock rom maybe...-. Also, he says that "I will erase every partition, backup partitions by enginner firmware and just rewrite your IMEI, then problem will solve." Is that true? Is there a "engineer firmware" for LMV600AM?? if there, anybody please pass over to me??
3) I follow "https://www.hovatek.com/blog/fixing-this-phone-is-permanently-locked-on-lg-v60/" this solution, so now my phone is currently T-Mobile firmware(v30b) and my S/N is changed to other number. Still, network doesn't work. Fun thing is that when I boot the phone, it says "you have to unlock network by unlocked app". But when I go to mobile network menu and tap 'network unlock', it says "this phone is permanently unlocked and can use any carrier." And still network doesn't work. What's the problem??

Are you crazy? overwrite original EFS partitions?? That will permanently disable modem because your 30c backup does not contain their original Modemst, fsg and fsc.
