First of all, hello.
Second, let me explain the problem:
I accidentally soft - bricked my ZTE V987.
That would not be a problem if I didn't also lose my ROM backup.:crying:
What I did so far while trying to fix it:
1. Tried to re - install Bruno's CWM recovery through SP flash tool - was unable to. SP flash tool enable dram fail error.
2. Found out I needed a preloader.bin, found one that worked (have found few preloader.bin files for v987 but all failed to flash except one) - flashed that.
3. Tried Cwm again - success.
4. Instaled Bruno's 3.0 mod rom through CWM, success, but lost Baseband, IMEI, Serial Number, BT and WIFI MAC Address.
5. Tried installing zte v987 china stock 1.0.1 rom through cwm - success, have baseband, but no IMEI, no Serial Number, BT and WIFI MAC Address.
6. Found about sn write tool, used it to restore IMEI and WIFI MAC address - success, BT & SN - fail: SN says it is written yet it is always displayed as 0123456789ABCDEF, but BT MAC sn write tool always fails with BT DB write fail error.
So, from what I managed to figure out, I need either a full ROM Dump from a working ZTE 987, and a way to insert all these numbers back in, or any other way to fix my phone.
To anyone willing to help, thanks in advance, and if this thread is in wrong subforum I am very sorry.

V987 IMEI invalid
I have a very similar problem; V987 showing invalid IMEI numbers but WiFi, BT etc all working. SN shown as 123456789ABCDEF. Phone does not recognise the Engineering mode code or offer an option to enter it via Gravity box. I can't get the IMEI & SN Writer tool to recognise the phone.
I have another V987 with stock ROM - does anybody know how to dump the ROM so I can copy it to my other phone?
(The links to the stock ROM on Bruno's thread do not work)
Edit: Problem solved! I used MTK tools to make a NVRAM dump of the stock ROM then the Flash tool to copy the ROM to my old phone. The strange thing is that the phone remembered the correct IMEI and SN numbers. I now have two fully working V987's!

Hello! I have a question! How did you complete step 2? I still have my V987 bricked and I can't seem to find an appropriate preloader.bin to wake it up again. I know I'm not exactly helping you, but I would be so grateful if you can help me out with that! I have less than 5 hours with this new ZTE and I already messed it up
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:
https://forum.xda-developers.com/ze...onor-qcn-file-ze550kl-z00ld-ww-t3520647/page4 (Page 4-5)
(Normal boot using a custom rom?? Interesting... maybe Xiaomi.eu made no difference for me because it's still pretty much just MIUI)
https://www.youtube.com/watch?v=8Ym0FP4BkY0 (The bottom comment):
"We cannot repair both SIM slots.
We can only repair SIM2 slot for IMEI repairing. After IMEI repair process, SIM1 IMEI getting '0' value. When we are trying to repair both SIM slot phone is entering the Bootloop and entering the recovery mode(twrp). Thats why we are remove SIM1 IMEI from qcn file and this time we can will repair to SIM2 slot. Do you know this Problem ? What can we do to solve this problem? Thank you in advance for your help."

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

Just flash the SIM 2 QCN I provided (edit the IMEI), and write the IMEI using pirated box software for free, you can find everything you need on YouTube. When I had the problem, pirated box software for the Mi Note 10 wasn't available yet

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..
i have problem with mi 8 no basedband unknow and restart.....no qcn write...try with UMT or QFIL not work.

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!
