I FLASHED THE ROM AND CWM RECOVERY (DON'T KNOW FOR WHAT CAUSE) AND ENDED UP ON DEAD PHONE
SOMEHOW I FLASHED THE ICS_V30B USING SMARTFLASH
BUT LOST THE IMEI AND LOCKED PHONE.
CAN ANYONE HELP ME..AND GIVE ME STOCK BIN ROM SO I CAN FLASH AGAIN..WHICH RECOVER MY IMEI AND UNLOCK THE PHONE.
THE GUIDES FOR RECOVERING IMEI ARE USELESS AS I DON'T HAVE IMEI WRITTEN ON BACK OF PHONE OR *#06# (CHECKED MANY TIMES BUT NO IMEI.)

[Q] Zte v987 bricked, how to fix.

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

Weird Logic Board Issue??

I am 100% sure the phone is a D800 (per the logic board )
If I try to flash D800 or D801 STOCK .tot firmware....they both will show null/unknown baseband, imei, etc. AND constantly reboots
If I flash LS980 STOCK .tot.....the phone shows the information (not null/unknown/blank) AND doesn't have the rebooting issue
(FYI: after booting into the stock ls980 zvc rom to get uninterrupted adb access to the phone, I changed the imei using QPST tool, to the imei numer that is on the inside of the backcover, because it was showing a wierd imei like 35030526000000.....Now everytime I flash the stock ls980 rom, the imei seems to reads correctly...so im guessing that stuck)
I also tried to flash custom LP based roms......I flashed the LP bootstack, then Blisspop.......and It bootloops right at the blisspop logo starts to appear (this is from stock .tot fresh installs....cleaned wipe) then keeps looping to LG logo then partial blisspop boot animation.
So, the common denominator seems as if the phone/logic board refuses to let any D800 or D801 baseband be flashed properly to it......So far ZVC (stock sprint kit kat) is the only baseband that sticks and lets it run any roms without rebooting.
I've never seem this issue before.......is this phone banned, blacklisted or something?

restoring imei

i had corrupted efs partition i took it to a local repair shop they fixed it. it was rooted and downgraded to 5.1.1 and the imei was changed,..right after that i backed up my efs,flashed official 6.0.1using odin and then i flashed xtrestolite rom.but in xtresolite rom it does not shows imei while i press *#06# but it shows imei in about device/status/imei information and there is no issues like emergency call only.i tried flashing my backed up efs partition but the result was same. now the question is it fixable ? and can i restore my original imei as i am planing to sell the device.
It's just a ROM problem. If you want to sell the device, just install stock ROM.
I dunno, I have XtreStoLite and *#06# shows IMEI & S/N. Don't think it's a ROM problem. Did you ask guys at repair shop about it?

Oneplus 6 unknown baseband, no imei and meid issue

Hello everyone this is my first post as i can't find the solution to this problem any help will be highly appreciated.
So in september 2020 i faced qualcom crashdump mode issue in my oneplus 6 i tried flashing it with msm tool many times but the issue was still there so i tried msm smt download mode and yes lost my imei number and the phone was still facing qualcom crashdump mode so i gave up and bought a new phone but this oneplus 6 was still with me and then few months ago i heard that the phone was booting up my reballing the emmc and then i asked mobile technician if they can do this so they warned me that there is a dead risk too means there was 50-50 chances of reviving the phone. I took the risk and yes my phone was revived but then i faced this issue of unknown baseband, no imei and no meid the technician was also not able to fix this so i am here i tried flashing different roms but nothing worked.
yesterday i don't know how but when i woke up in the morning i checked it and i was surprised that imei was back wifi was working but sim was not working so i restarted it and again everything was gone no imei, unknown baseband
If anyone knows how to solve this please help

Just use MSM tool. There are a few of them in the Guides section. Read instructions in the thread for that MSM tool, which involves installing certain drivers on your windows PC, as well as putting your phone in EDL (emergency download) mode.

i believe that you tick the SMT when flashing using MSM?
if yes, AFAIK you can try to flash using SMT again.
Did this work out? I'm in a similar position with my Oneplus 6 and can't get Wifi or IMEI back.
I have same issue brother no sim wifi baseband unknown
yes bro flashing with msm smt download fixed my problem you can give it a try
once your baseband is fixed than imei restoration is easy
I try to flash whith smt but if give error after some time start flash
Anyone fixed this issue or not?
i flashed a couple times with msm (tmobile version), but this didn't fix my issue of unable to turn on wifi. this msmdownloadtool installed tmobile android 9.0 stock rom which didn't help fixed the issue. i then tried full resets and wipe data. still didn't work. i was going to give up, then i thought just do System Update thru cell data (since no baseband means no wifi). it installed the android 10 stock rom, and fixed the issue. now i have regain baseband and wifi.
hope this help anyone with the same issue
It could be a HW problem with the network IC (very common) but trying SW solutions like flashing first is advised
