Restore IMEI on your BlackView BV7000 Pro - fix - Android Q&A, Help & Troubleshooting

It's almos a year that I have damaged something and my BlackView BV7000 Pro keep saying "Invalid IMEI" (https://forum.xda-developers.com/android/help/invalid-imei-problem-t3898950).
No app or windows software works, I just managed to restore ONE of the two IMEI, but still having problem with some SIMs.
I finally managed to set my IMEIs, and the way is so simple that I wanna destroy it.
REMEMBER: this guide purpose is sole for restoring your IMEIs due to problems with your phone (like I did formatting all in the memory).
Using a different IMEI is illegal in most countries (if not all countries).
Here you go:
- dial *#*#3646633#*#*
- in Telephony tab scroll down to GPRS option (note: "CDS Information" option doesn't exist in this phone)
- now you can write both your original IMEIs (you found them on the back of the phone or on your phone box)
- reboot
I just find it randomly checking every option. And I used all tools I could find without luck (SP Flash, MTK Tools, IMEI Changer/Restore apps, etc).
Now my problem is fixed.
Enjoy.

Where should I enter the IMEI on GPRS option? thanks for your help man.

[Q] IMEI is correct but no network detected MT65xx

First I'm so sorry if my question is similar with another threads. But I'm pretty sure I have been looking for the answer around the internet and of course XDA developer for a week. I follow every guide and method I found. But it still not answer of my problem.
I flashing camera driver I've got from my friend backup using TWRP backup. Actually I only need to choose uboot only to install. But I'm in hurry so I accidentally choose everything includes NVRAM. Since then I've got wrong IMEI on my phone because the IMEI overwritten with my friend phone. But it's not a problem because I can restore my original IMEI with MTKDroid & Tools.
And the problem is my IMEI is now back and corrected. But there is no network detected on the phone. SIM card detected fine. When I go to EngineerMode by pressing *#*#3646633#*#* and open Radio Information on CDS I saw IMSI field was unknown and Radio Status is turning on and off rapidly.
What I have done is :
1. Full flashing with the stock ROM via SP Flash Tools.
2. Change the IMEI with MTK Droid Tools
3. Change the IMEI with AT command ... echo 'AT+EGMR=1,7,"myIMEI1"' >/dev/pttycmd1
No result. IMEI is correct but no network.
I believe this is not a hardware problem, so please help me to solve this problem. Because it's my only phone to communicate with my whole families. I really appreciate with your help. Thanks.

need help to restore my IMEI

hi Guys,
First, I apologize for that I'm doing the hundredth post on this topic
and secondly, I apologized for my "google translator english" (unfortunately I can not so good English because I am from Germany)
to my problem
I had the "Cyanogenmod 11 nightly" ROM on my Samsung Galaxy S 3. By the time the system was slow and I have flashed the latest CyanogenMod Rome via Odin on my phone. After the reboot, I had no connection to the mobile network, my serial number consisted entirely of zeros and my IMEI was not like it is in the battery compartment.
I have now spent several days trying to find a solution but for all IMEI Restore tutorials have not brought with me. Unfortunately, I did not know much about even before the Android system per se and the EFS folder and have therefore no backup.
I tried the IMEI
restore the NV_data.bin + NV_data.bin.md5 method​Result: IMEI was still so wrong seem right that my IMEI is no longer located in the System​
restore with the downgrade to a German MG6 Android version​Result: IMEI was still not right​restore using tools like QPST + nv ReaderWriter or EFS Professional​Result: EFS Professional -> Qualcomm NV Tools (after efsprofesional the mobile phone has put into the correct USB mode) -> connect to my phone broke off as soon as I wanted to read or write
QPST + nv ReaderWriter -> gave me appear not correct port on my phone
all the drivers I have installed clean and tidy. After further investigation, I found out that I need a special UARTcable this (and maybe a Z3X Box or something similar?)​
My question is
How can I get now establish a new nv_data.bin file that includes my right IMEI
or whether (if it is really expensive) someone is so net and created me such a file
my Hardware is Samung Galaxy s 3 (i9300) (unbranded) (may u need this too: i bought it in germany)
I only want my own IMEI and I do not think out a like or I like to personally via PN or so to sample photos (for example, a predetermined word from the person) and the battery compartment of the phone with the IMEI
for I illigalität knows that it is illegal but not his own restore its IMEI change, because you paid a lot of money for his mobile phone and the IMEI is jointly contain. Who's afraid these publicly to write here because this information could be misused can I enjoy writing via private message. I would be very happy
Now im trying again to solve my problem with this Tutorial -> https://www.youtube.com/watch?v=XT42ri37RBU
my preperations:
im installing now a fresh windows 7 on my Laptop​
i flashed I9300XXUGNG3_I9300DBTGNG2_I9300XXUGNA8_HOME.tar.md5 (SGS3 Stock Firmware DBT with android 4.3) downloaded with the SamFirm tool from http://forum.xda-developers.com/galaxy-tab-s/general/tool-samfirm-samsung-firmware-t2988647​
i rooted my phone with Odin3 and CF-Auto-Root-m0-m0xx-gti9300.tar.md5​
i put the usb debugging on (settings > options > about device > [clicked 7 times on Buildnumber] that activates the developer menu and i put usb debugging on in settings > options > developer options > usb debugging)​
i´ll post the results
dont work for me becouse "ONLY for US variants. It DOES work on Qualcomm CPU and DOESN'T work on Galaxy International Version with Exinos CPU!"
someone maybe got antoher way to fix it?
@sLeCks:
1. Flash last firmware with Odin (again), go to recovery immediatly and do factory reset.
2. If 1. doesn't help, try Ariza patch.
3. If 2. doesn't help, let it repair by Samsung-service (cheap).
Firmware Update dont restored IMEI (got still 0049 imei)#
Ariza patch wont help it just restore the baseband (like written in the Thread "wont help if u goot a 0049 imei)
maybe it works if someone got a i9300 (intl) (exynos NOT Qualcomm) and a z3x-box or another. i send him my right imei-number he backup his efs folder and create the right nv_data.bin file for me. then he send it to me via email or he put it on uploadet in ecample. i download it in put it on my phone and restore my imei.
maybe i think is a full efs.img backup file better xD. if this way work it would be the best i think.
Ißve called some mobile reperature stations an mony of then dont do an imei-restore. i got one and go now to him maybe he can help. but if someone got a box and a old sgs3 i would be sooooooo happy if he could help me.

[Q] MTK MT6582 IMEI repair failure

Hello XDA, I have been a user/fan of xda for about 5 yrs now. But I havent found a single problem that I didnt find the
answer for here on xda, or somewhere else (Google). I have a Computer and Phone repair shop in Ethiopia and I used the
internet and mostly XDA to Unlock Sprint HTCs, Unbrick Galaxy S/ SII/ SIIIs, repair corrupted efs partitions, install
custom roms like CM (on almost every smartphone I come around), fix bootloops of Best devices like Xperia Z, Galaxy SIII,
Sim unlock Moto Droid ...
But I have faced a serious problem and have been trying to solve it for about three months now.
To the real problem
There Are these MTK MT6582 Devices, Mostly Huawei devices (G730, G610, G630) and they are recently getting a major IMEI
failure (IMEI : null). I have tried through the ff methods (that I use for other MTK devices like MT6572, MT6575) With no
luck
1. Maui Meta 3G - It reads the devices in meta mode
- It can read the version (in "Get Version" window)
- I have selected the Nvram database of same baseband
- It fails to write the imei when I click "download to flash" It either replays "Check the load and device versions are the same (ish)" or "Download to flash time out"
2. IMEI & SN Write tool - Doesn't seem to read the device in meta mode.
3. MTK Droid - Rooted the device
- Restored "nvram" from another working phone
- Rewritten the IMEI
- Still the same (IMEI: Null)
4. Reformatted the whole device and installed firmware with "secro" file - Still the same - tried the above methods again, still the same.
Dear XDA Fellows, I am exhausted with these devices and they are keeping coming. So, Please help me solve these problem. Thank You.
P.S - I dont know where to post this, if there is another appropriate thread, lead me.

Nubia z11 mini - NX529F - Telephony services lost

The short history:
Playing with an "official" ROM I bricked my phone. I was able to recover it, everything works properly except the telephony, I can't make phone calls :crying:.
The full story:
The behaviour of my phone is different depending on which slot I put my SIM card.
If I put my SIM on the first slot, when the phone reboots it doesn't ask for the PIN and doesn't recognise the card. But if I switch to plane mode and I reboot the phone, the phone then asks for the PIN number. If I introduce an incorrect one, it recognises that it is incorrect ans ask for a new one (then it is reading the card to know that), but when I introduce the correct one, it does no connect whit my carrier (of course, before that I switch off the plane mode).
If I put my SIM on the second slot, it asks for the PIN number but similarly to the previous case, It doesn't connect with the carrier.
In both cases dialling *#06# on the phone, I can read the two IMEI and the MEID codes and they agree with the codes printed on the phone box.
Moreover, if I install an app (I tested with some of them) that reads the SIM card it can read the name of my carrier and all the contacts that are on my SIM.
Things that I tried:
0) I tried to use my SIM in another phone, and it works. I also tried to use another SIM in my phone, and I have the same problem.
1) I tried to install several ROM's:
- Jeff72ROM (v1.30 and v1.32) from: http://www.needrom.com/category/zte/serial-nubia/z11-mini/
- stock ROM from http://4pda.ru/forum/index.php?showtopic=776504&st=0#entry52586301
- And experimental port of CM14 (I can't remember where I found it)
- CUOCO92 from http://blog.grossoshop.net/nubia-z11-mini-rom-gs-by-cuoco92/
- An "official" ROM: NX529J_Z69_EN_NSXPK1JD00K132 from http://www.nubia.com/es/support.php?a=phone&pid=8 (this is the ROM that bricked my phone, I modified it in order to avoid the problem).
To install all these ROM I used TWPR from http://www.androidbrick.com/download/z11-mini-nx529j-twrp-root/
When I dial *#*#4636#*#* on the phone it says that the type of preferred net is WCDMA. It seems to me that these nets are not in use in Europe (I live in Spain). Itried to change that, but I couldn't. Then I applied the patch http://forum.xda-developers.com/showthread.php?t=2394689 but it doesn't work. I also tried to modify the properties in "build.prop" without success. Now I think this is not the problem since all the ROM's have similar properties, in special CUOCO92 that is reported to work in Italy.
What I think it happened:
When I tried to flash the "official" ROM it failed because it tried to write too many files in the "system" partition (I hadn't this problem with any other ROM). Then I realised that my phone was bought in China and this ROM was for the international version, perhaps the international version has a different partition scheme).
What I did is to remove some very easy to install apps (i.e. google maps) in the ROM in order that the remaining apps fit in the partition, but then I made the mistake to activate the option in TWPR of making "rm -rf" instead of a "format". It seems to me that with this option the rm command followed some link to another partition and removed some files that shouldn't be removed, and those files are not in any ROM.
Does anybody think that this makes sense?
What can I do?
nice, super description. i am stuck with my nubia z11 mini, brought from china. installed 1.23, recently updated new 1.36 but there is no google play, other all working perfectly.
Hi,
I have the same problem. Did you find a solution?
Thanks in advance, F.

@jbartolo
I have the NX529J and the option wasn't changed, it was still format. I don't think the problem is related to the partition.
@jbartolo
Any news about your z11?
Did you manage to fix it?
I have the same problem.

No solution :crying:
I had access to another z11 mini and a played copying partitions from this phone to my phone without success.
@jbartolo
Since you can have access to another z11 mini please check these guides
http://www.androidbrick.com/unbrick...-have-the-right-kind-of-rom-qhsusb_dload_edl/
http://www.androidbrick.com/ultimat...agon-xiaomi-mi5-imei-and-baseband-repair-fix/
http://www.androidbrick.com/ultimate-guide-qualcomm-snapdragon-imei-baseband-repair-fix-part-2/
Also you will see more guides in the mentioned site and maybe you can fix your phone. Unfortunately i dont have access to another z11 mini to try. Wish you good luck.
@jbartolo
I did some progress with my phone.
I flash it with the chinese 1.23 rom(its the one in fastboot structure as i understand,a service rom) using Xiaomi's MiFlash tool.
Phone came up with null IMEI'S and MEID. Then i write missing IMEI'S & MEID ,with some tools from the site i mentioned you in my previous post.
So everything is in place now. IMEI'S & MEID.
Now when i dal *#06#* and *#*#4636#*#* i can see Imei's & Meid.
Also i can change the option from WCDMA preferred to other options and stick with them (*#*#4636#*#*) and i can see in phone settings and SIM menu all the options.
Both sim trays read my sim and ask for pin.
In SIM menu, i can search for avalaible carriers but the only problem now is that when i'm trying to connect to my sim carrier unfortunately phone can't register to my carrier.
I'm trying to figure out how to solve this issue.
You can try what i did and maybe you are more lucky than me and can fix your phone.
Hope to hear from you soon and maybe we can share some more ideas.

You could contact the owner of www.androidbrick.com in case he has one. Or you can ask @jbartolo to provide a backup of his other device. Taking a qcn backup is a pretty simple procedure
@efrai3 Just contacted him again and he was happy to share with me a qcn backup for your device
You can contact him too and ask for one! He will be glad to help!

problem solved: Z11 mini working again
All,
the AndroidBrick method worked.
First I tried it with my own qcn backup but that didn'twork. I received a qcn (Chinese, 64 GB) from AndroidBrick and I followed the repair guide. My Nubia Z11 mini is working again.
The solution for our problem is that you need a qcn backup from a working phone because when you install the wrong rom (international version) the modemst-partions are corrupt.
I'll prepare a backup qcn from my phone (changed IMEI) and I can send it to you.
Send me a mail at [email protected].

I will be happy to give my email address for your (or even other God) help.

Invalid IMEI - Help me!!!

I recently tried installing this rom https://forum.xda-developers.com/vivo-5/development/rom-aosp-6-blu-vivo-5-clones-t3489281 but it did not work very well.
It is now appearing as invalid IMEI.
Any idea what I can try?
I've tried the MTK Droid tool, MAUI, SN Writer but none of them recognize the smartphone.
Try with this:
PD: Have you problems with WiFi?
For a temporal solution you can use MTK Engineering Mode (The Monster) from the Play Store. I think maybe you need to be rooted.
MTK settings
Connectivity
CDS information
Radio Information
you will see AT+, delete the plus , add the plus sign choose the first option (in my case AT+EGMR=1,7,"")
Put the your EMEI in between the comas "EMEI" if theres an error put a space between the + and EGMR
for the second EMEI select the second option AT+EGMR=1,10""
This will work until the phone is reset
