This is without a doubt the worst forum for a device I have ever seen In my life...

Why did no one start a separate topic about repartitioning your phone? In staid of 80 pages of people all talking trough each other about separate things. In most other devices forums moderators just close the topic when this happens.

I'm a bit confused I followed the first part gave it a try now my phone's storage is not recognised... I would be happy to write a tutorial myself like I did for the ZTE Skate (LINK) but I simply can't find the right information in 80 pages.

Edit: Ok I got it working, this isn't my finding so it would be better that the ones responsible for finding this make a topic. If no one want's I could make a fool proof topic about it. Because I'm 100% sure that many people will have this problem. :)

I used flashify to flash the stock recovery. I confirmed it was on there by rebooting into recovery and could see it was the official one again.

But still cant install 1.76 update OTA. it downloads, reboots then gives a update failed message, complaining about some apk files (facelock.apk). I think the actual file is irrelevant as if I delete that it will just complain about the next one.

Im running the official firmware 1.62 at the moment, only thing I did was flash the gapps. Do I need to remove that before i can use the official update??

also does anyone know where i can download the 1.76 update only file (130mb) Only one I can find is the full firmware 700+mb I dont want my phone to keep downloading it every time it fails.

Hello

Ive just flashed the last update by cuoco, but it's not working properly.

When I Tap the msim settings, sound settings, apps, it crashes (unfortunately, settings has stopped).

Does anybody has the same error?

I've tried to delete cache from twrp and clean with sd maid but it didn't help (sd maid also crashes when I'm trying to get the app drawer).

[ZTE Z7, Z7 Max, Z7 Mini] Leo_83:

[ZTE Z7, Z7 Max, Z7 Mini] Leo_83:
Well the idea was to do a clean installation of the latest release and then do the minor updates again, so no. Unless you can find out what went wrong exactly and correct it.

Try holding in the power button for about 20 seconds when the phone reboot, repush the power button and hold in volume up button as well... That would get you to the recovery from there you can reinstall the rom your were using before.

[ZTE Z7, Z7 Max, Z7 Mini] flamery:
Do you have a backup of your imei? if not you may be in trouble. there are plenty of apps that can flash your imei back, but if you dont know what it is then your stuffed. if you have the box, or the stickers you may be able to retrieve it off that, (maybe its under the cover of the phone?) Anyway if you do have the number. just get the tool "XPOSED IMEI Changer" and put it back on.
[ZTE Z7, Z7 Max, Z7 Mini] staticx1:
Hey thanks

I do have my two IMEI's written on the back cover...

I've managed to install the IMEI Changer addon, I was able to write again only one of my IMEI's (I guess the app doesn't support dual-sim)

[ZTE Z7, Z7 Max, Z7 Mini] flamery:
okay, I think above tool does not work because nubia is not mtk. try this method for snapdragon: http://cellphonetrackers.org/change-imei-number-snapdragon-device.html

As you are just editing the file manually and typing them in, you should be able to install 2 imeis without an issue.
[ZTE Z7, Z7 Max, Z7 Mini] staticx1:
you're right, the problem is, that because both of the Imei's are null, I cannot find them on the qcn file with the Hex editor... so I don't know where to write to new IMEI's...

:(
[ZTE Z7, Z7 Max, Z7 Mini] agora.basta:
Starting at offset 0002ed60:08 there's the first IMEI. Enter it as per the article linked above. But I don't know where the second IMEI is stored, only know it's not coded in the same format, most likely there's a differential value somewhere.
[ZTE Z7, Z7 Max, Z7 Mini] staticx1:
oK, I've found that, and it was already written (because I've already use Xposed IMEI changer) but when I do *#06# I get "Null" on IMEI1, IMEI2 and MEID...

also, when I'm trying again to restore RAW file from other nubia phone, the flashing process stop after a few seconds (on 135,000kb) ...

I really don't know what to do...it seems like there's no way to restore it back...

can someone send me EFS directory so I can only change the IMEI's?

I'm trying to follow that guide:

http://xdaforums.com/galaxy-s2/general/guide-recover-imei-9-steps-t1264021

but every time I create efs folder, it gets deleted after reboot...
[ZTE Z7, Z7 Max, Z7 Mini] flamery:
I was going to send you mine, but came to the conclusion that my Nubia does nto have an EFS folder. well it snot in /efs/ as it would normally be, tried searching for it too and cannot locate it. maybe that is the problem.

I found another method, maybe worth trying?

1. Connect phone by USB

2. Enter 1809#*990# in dialer

3. Select Port Settings -> Select CP USB

4. Start hyperterminal, in COM settings select same port like in devide manager -> LGE mobile USB Serial Port, 115200

5. Type AT if response is not OK, change port number

6. Type at%imei, it should display your current IMEI

7. Type at%imei=x,x,x,x,x,x,x,x,x,x,x,x,x,x,x , where x,x,x... is your orginal IMEI number

8. Reset
[ZTE Z7, Z7 Max, Z7 Mini] agora.basta:
You can manage it all yourself :)

1. Go buy a new phone of the same type.

2. Backup NV param's from the new and restore into the old one.

3. Edit the restored NV items' values as needed.

4. Sell one of the phones at some discount. Or for a profit...

Voila!

It is supported by the hardware, the standard is in there, it should be just another frequency that has to be added or enabled in the baseband firmware, but should probably come from Nubia themselve.

backup problems

Hi all. The entire time that I have had my mini I have used CWM as my recovery. Last week I wanted to try installing Cuoco's rom and switched to TWRP. After not really being fond of it, I switched back to CWM and also back to Mokee. Here's my problem, regardless of whether I use CWM or TWRP, neither of them properly do a backup for me now. They both create corrupt backup files that don't load and delete themselves accordingly. Fortunately, I do have one backup but it is from December; needless to say, it's a real pain in the a$$ to update things all over again. Does anyone have any suggestions for how to fix this or what may be causing this?
[ZTE Z7, Z7 Max, Z7 Mini] mightymaki:
I think it may be the recovery itself. CWM never backed up properly. I had the same problem until changing to a later TWRP version. Have you tried TWRP 2.8.3.0 (material) or 2.8.5.0? I have used both of these to successfully backup & restore several times without failure or being corrupted.
[ZTE Z7, Z7 Max, Z7 Mini] PAG09:
sorry,wrong thread
[ZTE Z7, Z7 Max, Z7 Mini] pedrud:
Thanks for the tips. I couldn't find a link for 2.8.5.0, so I used 2.8.3.0 material. Same issue, no valid backup. This is getting really frustrating. I flashed 2.8.3.0 with flashify and it seemed to work fine. I also tried to transfer the TWRP file for the digirom and the file somehow disappeared - twice.

[ZTE Z7, Z7 Max, Z7 Mini] mightymaki:
Yep, I've been having similar problems with that file. You need to make sure it is in the TWRP backup folder, but it is quite specific. When you open your TWRP folders, check to see what is created, i.e. is there a "backup" folder & a TWRP folder? I had to drop it into both folders to make sure & then I could see it. My problem now is that the latest digirom file appears to be corrupted? Again, not sure if it's the file or the recovery?

Bricked nubia z5s nx503a

Hi there. Recently I flashed a ROM which rendered my phone useless. The ROM is an official one from but H2.12. I flashed using CWM. After flashing, CWM prompted me if I wanted to flash the custom recovery with the official recovery which was in the ROM. So I clicked on YES. Then trying to boot the phone, the only thing I saw was the white screen with the Nubia logo inside! Pressing volume+ with power combined I still see the logo. It looks like it doesn't have a recovery ; neither does it have a ROM. Right now I've tried several methods but nothing is working. So how can I install a new recovery mode inside this phone? Remember the phone has no recovery nor a ROM.
[ZTE Z7, Z7 Max, Z7 Mini] Leo_83:
You need to do an adb flash of the recovery. There are YouTube videos on how this is done.
[ZTE Z7, Z7 Max, Z7 Mini] balozi007:
Is it different for each phone? And is there still hope after I try it?
[ZTE Z7, Z7 Max, Z7 Mini] Leo_83:
Yeah don't worry, you will get it working again.

No the procedure is basically the same for all phones. The only difference is the the file you use and how you put your phone on fastboot. For the z7 mini is volume down + power button, so similar to booting into recovery but different push on the volume rockers.
[ZTE Z7, Z7 Max, Z7 Mini] balozi007:
So which program should I use for that?
[ZTE Z7, Z7 Max, Z7 Mini] Leo_83:
I assume you have Googled it?

But okay... You need to install android sdk on your computer, set your phone to fastboot, then via command prompter run commands from within the sdk android directory that install the recovery.img file.

So you can do it without reading about it and just follow just the instructions above but if I was you I would read and watch YouTube videos, because I just wrote that out of my memory. For the exact steps you need to do some homework.

[ZTE Z7, Z7 Max, Z7 Mini] OpenMinded:
to recover EFS, check the nubia backup folder.

Run the updater tool, click the logo, choose the third option.

That should load restorer (can be started directly).

If you made a previous backup, check for the files, move empty ones away.

click the button and EFS with IMEI and stuff is back.

Thought I posted it because I saw someone having issues.

I also noticed with PA Gapps that after a factory reset, the setup loads and crashes settings at the end.

- rooted the phone with TowelRoot ( or another app, I didn't use KingRoot). I can't remember which TowelRoot version but it's only 3 ones. . Check it after with some play store apps. You may need to install SuperSu 2.4x and reboot several times.

- Installed Flashify - it works only on rooted phone .

- download TWRP 2860 from Androidiani .

- Install TWRP with Flashify . If it aren't working do unzip the TWRP archive and Flashify the .img file . Or use the file from 4pda.

- reboot to recovery and see TWRP.
