[ZTE Nubia Z9 Mini Questions & Answers] NvN77:
Thank you Aashish,

Your help made my nubia z9 back in game, appreciated from heart.

In the instructions i like to add some more points, to make the process more simpler: (These are some additional points for help, please follow the original instructions) :

4) Enble USB debugging on your phone and enable RSA security key box shown, when connected to your PC: Dont panic if no RSA security key box comes.

5) Now install drivers.exe on your windows 7 with your mobile kept on: Another way of installing drivers is by running the autorun to install drivers when you connect your nubia z9 with cd install usb option.

6) Once this serial port driver is installed check it on your Device manager-Ports settings. It should show USB Diagnostic MDM port: It could be like this also , USB diagnostic port com 12/13 or any other number, but remember to update the Set baud rate as 115200.

10) Select back up and press Settings tab in backup, and set baud rate as 115200: if your back up shows error, Also uncheck the PRL box.

Thank you Aashish again.

Hello, I'm actually a newbie and don't know much about flashing stuff on ZTE phones. I used to do a lot of flashing on my HTC phone, which was sorta easier. I needed a stock rom for my phone. It's the Indian version running and device info is v2. 8.1 nubia up, build number nubia NX511J_INCommon_V1.03 hardware NX511JMB_C. I have rooted it and it also has twrp. Please do help out. Want to unroot and update.
[ZTE Nubia Z9 Mini Questions & Answers] meconfusedthinker:
you are already on the Indian STOCK rom..since you are rooted & has twrp..take a system backup using TWRP..

FYI.. India users have not got any update after NX511J_INCommon_V1.03 .

Most users are using Chinese ROM (v3.75 stable) & doing the data gsm patch instructed in OP.
[ZTE Nubia Z9 Mini Questions & Answers] M_Aashish:
as described by [MENTION=5800366]meconfusedthinker[/MENTION] no updates available for indian version. u can do radio patch and use navin's rom without any problem
[ZTE Nubia Z9 Mini Questions & Answers] nhehern:
I'd like to know what this qcn backup is. Also, I don't see the rom link. Could someone give me a step by step guide? I have to start with the radio flash first right?
[ZTE Nubia Z9 Mini Questions & Answers] nhehern:
Okay I followed the instructions as told. But

1. in the step to restore qcn.... Do I have to set the baud rate as 115200 again?

2. While doing the patch, it said failed to copy 'file name' : read only file system. Then my phone screen shows this pop ups of super user granting some permissions for shell. Then when I press any key to continue on laptop, my phone reboots. Does this mean the method is complete? Also how do I know it worked? :confused: Please help. Also now am I able to flash any rom (especially the rom by navin)?. Awaiting reply

Thanks in advance.
[ZTE Nubia Z9 Mini Questions & Answers] meconfusedthinker:
copy all img files in the root directory of SDCard and run the patch again...

if all is went well, you will get NO card in SIM settings & after that you have to Restore QCN using Nubia tools to get your IMEI back..yes baud rate should set as 115200.

hi all,

i am nubia z9 mini (indian model) user, and it is a fantastic mobile to look at. the only problem is we are stuck at android 5.0.2 with nubia ui 2.8.

I would like to update my roms to v 3.75, as i don't think nubia will release indian roms any more.

Can some help me on this.

I downloaded the 3.67 international ROM and installed it, rooted it, and patched the gsm drivers.. Flashed the qcn file and got my IMEI BACK.

All went successful. But when i try to insert the AIRTEL SIMCARD, and try to load, it is saying Mobile radio parameters have changed and the phone will AUTO reboot and a button Load now is asking to be pressed. When i pressed nothing happened. but i can get the signal back, but no mobile data.
[ZTE Nubia Z9 Mini Questions & Answers] meconfusedthinker:
3.67 has few bugs. cud b an issue with ROM...try installing v3.75 & see...if not solved..try patching gsm files again after installing v3.75..but keep airtel sim on in the phone..
[ZTE Nubia Z9 Mini Questions & Answers] M_Aashish:
for solving this problem u hav to do radio patch..... described in first post
[ZTE Nubia Z9 Mini Questions & Answers] vinayshivakumar:
Did this on Windows 10. Just had to run the Nubia tools in compatibility mode. Other stuff worked fine without issues. Do remeber that you iwll have to run everything as admin. Make sure all your drivers install properly.

You will need to uncheck the PRL option when doing backup. This was missed in the instruction number 11. Took 20 mins to figure this out.

Also , for people who hate the useless menu touch button , you can remap it to recents using a simple hack :

1) open the /system/usr/keylayout/Generic.kl in root browser app.

2) Go to the following line :

key 139 MENU VIRTUAL

3) Change it to

key 139 APP_SWITCH.

4) Reboot and enjoy !!

[MENTION=6961433]M_Aashish[/MENTION],

First of all thank you for creating this workaround :good:

I found this thread while searching for an online solution for the shocking "SIM Card changed. The phone needs to reload network parameters..." message.

There's a difference though, this is happening on a Z9 Classical (NX508J), a friend of mine has sent me his device since he has no clue what is happening.

I understand that this happens when you flash chinese rom in an international version, but to my knowledge, the NX508J only has one single version, none international. I also asked in Navin_n's thread and he pointed out that this is a radio error and that the files that need to be patched are : persist.img, fsg.img, fsc.img, modemst1.img, modemst2.img ...

First I want to apologize if I ask you in this thread something for a different model, but since you wrote that the Nubia Tool is valid for all Nubia devices, I just wanted to double check with you.

I do not feel very comfortable in tweaking around with parameters in a device which is not mine, hence I'd like to ask you if you are confident that the method described by you works for all models or only for Z9 mini ? I don't even have the working Z9 files, nor do I not know if by following your method, this solves the issue...

Do you know someone that owns a Z9 Classic that faced the same "SIM card changed" issue ?

Maybe in the end it would be the wisest thing to just send in the device to the Service Center and let them check it... All is working on the Z9, only no mobile data...

Anyway, thank you for reading me and apologies for "dirtying" this thread.

Kind regards,

Ken
[ZTE Nubia Z9 Mini Questions & Answers] meconfusedthinker:
hi [MENTION=4339678]K3nshiro[/MENTION] dont know much about Z9 Classic, since it has a different hardware compare to Z9 mini...

maybe you can download the STOCK rom for Z9 Classic and look for NON-HLOS.bin file, if found & try to push via shell prompt..but then you will need device to be rooted..

or best, since its still in warranty..goto service station nearby and get it done..

If I am not wrong then these steps are for those users (using Indian version) who are facing data issues when updated to international chinese version.?? Right??

So first do I need to update to 3.75 vesion per forum

just out of curiosity, which ROM is good : official 3.75 version OR MoKee ROM based on marshmallow??

By "Good" i mean UI look and feel wise, feature wise, performance, battery life etc.

I know 3.75 has data issue on Indian version, though it can be fixed.

And hows nubia camera on Mokee ROM.?? Is it equally good?? Camera is USP of Z9Mini and if its not equally good on Mokee then no point in having MoKee ROM.

Dear all

Got z9 mini yesterday

only one sim was working for me at a time

i did a qcn backup and did as per instructions in first post and restored qcn using nubia tools.

now both sims are not connecting and IMEI of 2nd sim is lost (showing null)

i have tried 3.67 and now on 3.87 rom

analysing the QCN file in WinHex saw that Sim 1 IMEi is stored in line 105E0

some how Sim 2 IMEI is not visible in qcn file

can some one please tell me in which cell location (hex value) is IMEI 2 is stored ?

i have the IMEI with me , jut dont know where to enter it in qcn file

---------- Post added at 03:49 PM ---------- Previous post was at 03:42 PM ----------

can someone kindly provide the qcn backup file of yours ? i have searched alot in google but no help.

Day 2 and still all I have is a phone which cannot make any calls.

I am embarassed actually. I am not able to contact anyone as I am in a rural area and no way of getting duplicate sim for a week.

Kindly help brothers

I like this phone already for all other features :)

SOLUTION:

Finally got back IMEI for both sims.

If anyone has got this problem with z9 mini of loosing imei by incorrect backup/no back up:

1. Download https://drive.google.com/open?id=0B0...3dhR0xIcTVvWjA

2. Download Winhex editor

3. Open Z9mini.qcn in winhex

4. Cell "1F60" is SIM 1 IMEI replace with yours in Hexa decimal format eg: 866769020765346 is 8A66670902673564

5. Cell "19120" is SIM 2 IMEI. Replace with yours likewise eg: 866769020450345 is 8A66670902543054

6. Cell "35B0" is MEID. Replace with yours found in battery cover. (replace AD with A000)

eg: A000004E56EC83 is 83EC564E0000A0

7. Save the file

8. Restore using Nubia tools
[ZTE Nubia Z9 Mini Questions & Answers] jibeesh619:
But still i am not able to receive signal.

When I search for operator manually, available operators list is displayed for both sims.

But when I try to connect (Both my SIMs are BSNL-Personal/Official) error occurs.

When I select "Auto Select" also error occurs.

If i install Stock Indian ROM (1.0.3 ) and do radio patch, will it solve the issue ?

Help needed on Instruction manual

I am a nubia indian user. Initially i tried to install 3.67 without knowing it is not compatible with indian version and my data went off. So i installed international roms like Mokee, MIUI and data worked fine. I am in Mokee 5.1 now. I want to install 3.82 rom after taking qcn backup. First step in instruction manual tells that i need to be in stock rom.. Is it fine that i can be in Mokee or I need to do those steps when only on stock rom?
