Hey everyone, I need your help badly..
Device: Rmx2151
Android: 10
RUI:1.0
Bootloader: Unlocked
IMEI : NULL
Baseband: repaired
Problem level: software level(100% sure)
The Problem:
I can't use my sim card without wifi connect.
My nvram partion was corrupted, and so my IMEI and baseband was lost,(no backup)
I managed to recover baseband version by (as someone told me that it is mandatory to use sim card) deleting "nvram" folder from twrp file manager.
But my sim card still won't work, it only works when I connect to wifi, and as soon as i disconnect wifi the mobile networks also disappears,
Others who used the same method on this very device to recover baseband have a fully functional sim.
I also tried all other stock rom firmware files RUI1/2/3 A10/11/12
Heres how it looks:-

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/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.

Yes i know that we need a backup of qnc from another working phone in order to modify it and apply our imei's and meid, but where to find one???
It's difficult to have one as you understand.

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!

Thanks to my friend tassos_chry, my phone is fixed.
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.
Have a nice day and a good way
Hello,
I have an Elephone P8 (2017). After flashing an ROM image to the device, the NVRAM was overwritten and the operating system reported no IMEI. To fix it, I used the SN writer tool to re-enter the IMEI numbers, MACs and serial and re-installed the latest stock ROM from Elephone.
The IMEI numbers are back again but for some reason, the mobile network connection is only available for a limited time after booting. 20-30 minutes later, no mobile network is available anymore until I either reboot the device or toggle the SIM to be used for the mobile data connection.
Has anybody an idea how to get a stable mobile network again?
Is there possible that anything else is wrong or missing in the NVRAM beside the IMEI numbers?
This sounds like you flashed the release-version 20170722, not the first update 20170831.
Recheck. If in doubt, format whole device with SP-Flash-Tool and reflash 20170831.
Hello,
I installed the 20170831 stock ROM but "about the phone" in the android settings lists a baseband version with an older data:
Base-Band-Version: MOLY.LR11.W1630.MD.MP.V9.3.P10,2017/06/26 09:07
Kernel-Version: 4.4.15 [email protected] #1 Thu Aug 31 11:28:07 CST 2017
Build-Number: Elephone_P8_V11_20170831
IMEI-Numbers: 3598500800XXXXX
IMEI-SV: 78
SERIAL: ELEE800....
Same problem

Hi GoaSkin,
I have the same issue than you. I also overwrote my NVRAM and restored my IMEI with SN writer tool.
(If anyone think he bricks his elephone p8 (2017), he should try to flash a test version (he worked for me, when all the other version didn't work) then reflash with a recent version. )
SMS and 4G Internet works fine but phone call (3G/2G) don't work :crying:. (sometimes when I reboot my phone, it works again but it is rare).
I have the same version of Base-Band than you.
I will try to flash other version, to test if it works for me.
I'll let you know.
I found advices in other forums that people have similar problems on other devices using "Moly Baseband". They managed to solve this issue by using a different version of the moly baseband file when using the IMEI tool.
When you use the IMEI tool, you need to submit the baseband file beside the IMEI numbers and MAC addresses you enter. The baseband file comes with any firmware image. I don't know which baseband version was installed before I bricked the NVRAM partition but it is possible that the pre-installed version was a different one to that which comes with the (newer) firmware updates.
Maybe it is worth to try to downgrade the baseband version which comes with an old firmware image or to try if it is possible to use a baseband image that comes with the firmware of a different device also using Moly baseband.
Furthermore I found out using analysing tools that the phone is still able to get some information of the GSM network. Possible the mobile operator closes the network link caused by bad network requests.
hi i have a real problem here:
first the phone was completely frozen and the i decided to install the stock rom for it

Hi , first your device is x552 model not x522 but never mind .
In order to fix imei you need to flash nvram.bin and you need to allow in scatter file nvram.bin to be flashed.
First download this firmware:
https://www.4shared.com/get/H9yvkOUoce/MT6795__Infinix__Infinix-X552_.html
Once you download , extract on Desktop , make new folder on Desktop and put just MT6795_Android_scatter.txt and nvram.bin which you can find in Extra files folder.
Now in order to flash nvram.bin you need to edit scatter file and enable instaling that file .
Here you have easy video instruction to follow:
https://www.youtube.com/watch?v=-t408hG8SAE
If you solve the problem , edit this post as SOLVED!
Good Luck
Any One suffering from same problem, Below are Easy steps to fix Unknown Baseband version, NULL or Invalid IMEI and SIM cards / Network signal not detected on a Mediatek Android phone.
Before you proceed, ensure that your Mediatek phone has a valid Baseband (not NULL Baseband). If your Baseband is unknown then download the firmware for your model and flash using SP Flash Tool . Flashing the firmware to restore Baseband. With Baseband regained, you can then proceed with fixing IMEI.
You can use below mentioned tool to ENter EMEI again, But your mobile should show a valid baseband version or the below tools will not work.
SN Write Tool (SN Writer) method
Maui META method.
Hi,
I own Lenovo K9 Note having model number L38012. I know there are many threads like no IMEI, no signal, etc, etc, etc but none of them proved to be helpful. Moreover, I googled everywhere about the problem but I got nothing. The device I own seems to be very new. So, I need help.
The problem is that when I reset my device, it became FRP locked(in starting I didn't understand what was that since I'm a newbie). I flashed stock ROM but nothing happened. THEN I ERASED ENTIRE FLASH FROM PARTITION MANAGER IN QFIL TOOL . My phone became hard bricked but somehow I recovered from it and also now I can use my phone like before but the problem arose that I ended up with no IMEI, NO SIM CARD I somehow restored IMEI by using the QCN file of another device (Mi A1) since I didn't find the QCN of mines on google as mines is a very new device. I used the IMEI Rebuilder tool and edited the IMEI code from the downloaded QCN with my device's IMEI. In this way, I got my IMEI back but NO SIM CARD DETECTED AND WHEN DETECTED AFTER REBOOT, IT SAYS NO SIGNAL FOR BOTH SIM CARDS. ALSO, ACCELEROMETER STOPPED WORKING I tried several methods like:
1. fastboot erase modem (and modemst1, modemst2, fsg, cache, userdata, PERSIST)
2. flashed others PERSIST.img file found on different threads
Somehow recovered sensors like proximity, light and compass by flashing any persist.img but still NO SIGNAL, ACCELEROMETER NOT WORKING BUT SHOWING IMEI after dialing *#06#
ALSO, I DON'T HAVE BACKUPS OF SUCH CRITICAL PARTITIONS. I know I did a BIG MISTAKE.
So please can somebody provide me a solution ( or provide qcn dummy for Lenovo k9 note if someone owns such stupid device Also someone can provide me the PERSIST.IMG OR OTHER important partitions of the said device).
The stock firmware doesn't include these critical partitions.
My device specs:
Model: Lenovo K9 Note (L38012)
SoC: Qualcomm Snapdragon 450(SDM450)
Processor: Octa-core CORTEX ARM A53 @ 1.6 GHz
RAM: 4 GB
Please help if possible as I am afraid and I urgently need the phone. Any HELP WILL BE GREATLY APPRECIATED. Thanks In Advance...
Thanks
I somehow recovered the accelerometer by flashing persist.img found on the link https://forum.xda-developers.com/redmi-note-3/how-to/fixed-gyroscope-accelerometer-magnetic-t3522745
Now, the problem is when I insert the sim card, there is no network though IMEI is showing in *#06#
After dialing *#*#4636#*#* and heading to phone information, the radio state is showing OFF and signal strength = 0 in both sim cards.
In fastboot mode, bootloader version and baseband version are showing unknown while in settings baseband version is showing some string.
Thanks
Please someone reply soon
Hi,
Recently I have upgraded my S6 from android 6 to 7 and after the flashing was complete, I got an error message with DRK. So I run into Youtube for some solutions and at last I could fix that with flashing a Root file (https://shell.boxwares.com/Download.aspx?L=5772). It worked but ran into this SIM Card problem. It cannot detect the SIM and always says EMERGENCY CALLS ONLY. I did no back up for EFS. but my phone shows the IMIE and dialing *#0011# in the first steak IMIE says NG. Baseband is G920FXXU6ERF6. Before I was flashing the device the binary version was 5. So I tried binary 5 but did not work. So, I had to Flash binary 6.
What would be the solution for this? Please Help....
