hy,
I have a problem with a chinese dual sim it's a STAR B97 MTK 6575... AFTER A FACTORY RESET , i got a invalid imei.
The problem that I have with your first solution is that after I type the code for the Engineer Mode, in all of those options I dont have "CDS information"... ergo, I cant do nothing.. What do you advise next? p.s. how do I flash my phone stock firmware?
thx a lot!!!

Will this work for MT6589
Please let me know can I use the above method for Mediatek 6589 newly launched chipsets.

I have the new X920 (butterfly clone) MTK6589, and I have this invalid IMEI issue. I can manually get this fixed through your guide entering the engineer's mode. But everytime I reset to factory settings, the invalid imei error comes up. Is there a way to fix this permanently?

i'm also suffering with the same problem but i did not find any perm sol.
i think
it can be done if you have any previous backups of data partition before the invalid imei problem occured.

[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

[HELP]

Guys I got a strange problem. I can't turn on my radio on my phone. I tried turning it on with apps or calling *#*#4636#*#* but it didn't help. Any solution? Also I got an Mediatek mt6592 hardware

Using custom roms, radio and other things must be responsible. What last activity you did on your phone?

I think that I run Cyanogenmod 12.1 ported and then I installed my stock rom using SP flash tool because I needed it to call my friends. I reinstalled Cyanogenmod and then I reinstalled stock rom and now radio is locked.

Recheck that you are usinh the right rom and also check if you have imei number? Mostly flashing mtk will leads you too 0 imei, if you havw written some where the imei of your device try searching the thread "fix mtk imei no network"..
