Hi! 3.88 with gapps on nx506j

I finally found a way to install gapps on 3.88 without problem. Works every time, tested few times in a row. I was having problems with the TWRP also - it was not showing up even after 30 minutes of waiting onscreen time - only nubia logo and the phone was vibrating on touch, but screen was not turning off. This is what i did:

1/ After installing original 3.88 firmware I've rooted with kingroot and installed flashify.

2/ Downloaded the chinese TWRP /2.8.6.0/ and gapps 5.1 micro and copied them into phone internal.

3/ First I've installed gapps 5.1 micro with flashify/i've choosed twrp option when asked/. After that i didn't choose reboot on flashify, i've choosed flash more option and entered the home screen - the flashify done its job. This way the gapps was loaded into the phone, but phone needs to be restarted in order to install them. I can't restart yet because there is no twrp and if the phone gets restarted now the original loader will not install gapps.

4/ After that I've installed the chinese twrp like its written on post #65

5/ After twrp install the phone will reboot automatically but since the screen is always on with nubia logo you will not able to see the twrp - the problem that is known already and its written hundred times about it. The important thing is that in step 3/ I've installed gapps 5.1 micro and with the auto booting after twrp install on step 4/ the gapps will install automatically as we see only nubia logo. It takes about 2 minutes - after that the phone restarts and enters into home screen. Gapps are installed.

well my actual problem is that after i wiped everything accidentally, when i connect the phone to the PC i press power button vol + and vol - and i get a message that the internal storage needs format... 7 windows of that open... should i format it?
[ZTE Z7, Z7 Max, Z7 Mini] IceTea7:
I have the same issue if I press Start + vol(+) + vol(-) at the same time.

I just have closed the popup windows.

Is there anyone who can help me to put my Z7 into DIAG mode? I'm still struggeling to recover my IMEIs.
[ZTE Z7, Z7 Max, Z7 Mini] stanki6:
Can you see the device under the device manager? You can see "QHUSB_BULK" under the ports. Right click on this and update driver from this link(extract to a folder). Choose "Qualcomm HS-USB QDloader 9008" and i think it will help you identify the phone to the qualcomm program! I hope this will help you!

Hi.

I'm trying to put my Z7 in Android 5.0 but I can't get past the Nubia Updater.

Even with all the drivers installed it shows a red sign and doesn't let me update.

Any thoughts on this?

Thank you
[ZTE Z7, Z7 Max, Z7 Mini] stanki6:
What are your device manager show when you pluging the phone with power on and volume down pressed? Are you installed the drivers to the phone?
[ZTE Z7, Z7 Max, Z7 Mini] caKoo:
I installed the ADB drivers in my pc and in the Device Manager Appears "Android Device -> Android ADB Interface" with a yellow triangle.

And in Other Devices appears "Unknown Device" and "Android" with a yellow triangle aswell.

The Power On + Volume down takes a screenshot

Am i doing anything wrong?

PS: Got it... Hadn't installed the drivers that come directly with the phone duuuhh.

Thanks stanki6 :D
[ZTE Z7, Z7 Max, Z7 Mini] stanki6:
Your phone has to be turn off when you plug in to your computer, to boot in fastboot, this is why nubia updater can't see your phone. I suggest read the process again( I think it's around pages 22). Before you do the process save the modem config(QCN backup) with qualcomm SW.

Ps: I see now :D Don't forget to make a QCN backup!!

Can someone tell me if this is the latest version available?

you used nubia updater?

This rom didn't reformarted partitions?

I'm asking because i didn't tested....

Thanks

[ZTE Z7, Z7 Max, Z7 Mini] abumazn:
I didn't use nubia updater because it carsh on 15% from rom . i flash it by phone recovery .
[ZTE Z7, Z7 Max, Z7 Mini] Steveyknoxville:
Hi, you must use Nubia updater, recovery cannot reformat the single partion of lollipop into 2 partion for kitkat.

If Nubia updater not working. Uninstall Android drivers. Using your z7 while it is on kitkat reinstall the drivers from the phone while connected as a CD ROM under USB options. Reboot computer and try updater again. Start with the earliest full ROM you have.

Regards Steve

thank you for helping .

but make a mistake i download sd rom 1.26 i must downlaod wire rom 1.26 . i will download it and try to flash this night .
[ZTE Z7, Z7 Max, Z7 Mini] Steveyknoxville:
Cool. Let us know how it goes, I think you will find a 1.26 full ROM on señors Google drive, he has link in this thread.

Cheers Steve

I am currently in the process of making a custom ROM, it will be a few weeks before it's available.

It will be a lollipop based ROM, with full Google integration, Nubia enhancements like the camera. And fully debloated of all Chinese apps and stuff.

It will only work on lollipop though. It will need twrp, there is no twrp for 4.4.

Thanks
[ZTE Z7, Z7 Max, Z7 Mini] abumazn:
great to listen that new . wait you .

l download 1.26 wire rom but it carshed i try to flash and failed .

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

You may also have a corrupt ROM. Try and down load from some where else.

I download rom from other site but same issue . download from google drive share by senh0r but same issue .

I decide stay on 2.05 rom with viber problem .

thank you.
[ZTE Z7, Z7 Max, Z7 Mini] Senh0r:
hi everyone,

Attention: After this procedure the rom only have two languages, Chinese and English.

It's a original rom, so no google apps. You have to install it again, as the TheFrenchMan post says.

You will not able to install TWRP on android 4.4.2, it doens't work.

And please, do it at your own risk.

for those who want's go to rom version 1.26, you have to be on rom 2.05 and TWRP installed on recovery. Follow this steps:

1 - donwload file NX506J-update_V1.26 from my google drive

2 - copy this file to internal storage of the device

3 - get into recovery mode ( TWRP)

4 - on TWRP wipe partitions DATA and SYSTEM

5 - stay on TWRP and install the zip file, after the installation reboot the phone

6 - go through the setup, check the if the imei is ok *#06#, and ativate the factory and adb port *#7678#

7 - open Nubia updater and point to a folder with full rom version 1.26 ( decompress zip file: NX506J_CNCommon_V1.26.zip)

8 - update the phone with Nubia updater.

This way you will have the phone with rom 1.26 and the partitions reformatted.

Greetings

Senh0r
[ZTE Z7, Z7 Max, Z7 Mini] Steveyknoxville:
Hi Señor, thanks for your time and effort with this forum.

You say enter twrp and install zip then reboot and do setup and via Nubia updater install 1.26.

So my question is what zip do you install twrp. If it's the 1.26 zip why flash again via Nubia updater.

Thanks for making this clear.

Regards Steve
[ZTE Z7, Z7 Max, Z7 Mini] abumazn:
hi

thank you for good work .

but how can i flash twrp ?

i download it but can't flah it . so i can't do anything .

can you explain how flash twrp ?
[ZTE Z7, Z7 Max, Z7 Mini] Steveyknoxville:
Hi you have to be on 5.0 rom to use twrp.

Download twrp program from Señors drive, make sure factory port and USB debugging are ticked via the dialler method.

Connect phone to computer and open Nubia updater, make sure updater shows green tick. If yes close Nubia updater, you are not using Nubia updater. Just using it to make sure phone connected correctly.

Now unzip twrp file if it's zipped.

Enter folder and you will find one of the items your computer will call "application" click on that and the program will open. Then select option "2" then it will flash twrp recovery. When that's finished press option "3" and it will boot into twrp.

After rebooting phone with unknown sources allowed install apk, find apk on my post a few pages back where I link to a small app on my google drive, this apk will give you a button in your app list that when you click it and confirm yes, your phone will boot into twrp. Really easy.

Please thumbs up this if it helps you so others may find it too.

Hi, what ROM are u trying to flash.

None of the Z7 rooms are flashable via twrp. All factory roms must be flashed in Nubia updater.

I've downloaded Nubia Updater from two different locations now and both do the same thing. You launch it and then it just does nothing. I tried compatibility mode as well and nothing!
[ZTE Z7, Z7 Max, Z7 Mini] Biggenz:
I've sorted it. It was my antivirus that stopped the updater from running. Upgraded to Lollipop just fine and everything works including Gapps.

One thing though, I accidentally wiped my system data through TWRP and ended up without any OS and got stuck at the boot logo. I went back into recovery and flashed v2.05 with TWRP which worked fine. So it seems you can indeed flash a stock rom with custom recovery.

Hello. I'm just posting in this forum because I also have a nx506j bought in gearbest.

I've followed senh0r steps and i have, like he said, an android phone now!

I think if you are in the 2.26 version and make all the steps correctly, you might have the same results.

Many thanks for senh0r!

Now i put some screen shots of my nubia Z7 android phone.

Hello. I'm writing for the first time in this forum because i also have a nx506j bought from gearbest witch came with the 2.26 version.

I've followed the senh0r steps and now is, like he said, an android phone!

I think, if you have the original version, 2,26 and follow the steps correctly, you might have the same results...

Here is what I did:

1- updated the uncompressed folder 2.02 with nubia updater v1.1.

2-the same for 2.03.

3-updated the compressed, zip file with the in phone updater.

4-put the gapps, compressed, in phone.

5- installed TWRP and rebooted the phone.

6- with TWRP, installed the gaps zip file, then without leaving TWRP, or reboot the phone, go to the advance menu and root the phone.

7- finally, rebooted the phone into normal and voilá, its working perfectly.

I share with you some images of the result and an antutu test.

Many thanks to senh0r!

don t make the mistake

This phone , have very low support , if you wanna change the ui 2.2.6 , origianl firmware , you will never get it back (no firmware ) . I saw people that are sory that they don t make a backup , well don t be sorry .... if you have / haven t make no difference . Let s say you have a back up , how do you restore it ? No custom recovery for kitkat , no recovery menu from stock recovery . Nandroid backup is for cwm / twrp . No chance to restore in another way . Trust me i tried . So ....you stick with lolipop , that have battery drain issue ... or i don t know what to think . Tried all methods - flash again 1.62 ro (kitkat) with updater , and have battery drain also . My last chance is , ( that i don t try ) is a recovery image nandroid backup (twrp ) from another user (phone ) to install to my own , maybe make a diffrence , or a custom rom /kernel ( that i don t asspect to happen ) in next 2 yeras :)) . If someone can help with a nandroid backup i ll give him a beer :))

I have an issue with my Nubia Z7 (nx506j) When I am doing a normal call, the other person can hear me well; however, when I am doing viber, whatsapp or facebook messenger call, the other person cannot hear me at all, he hears me only a bit when I turn on my speaker only.

Ok, so after a couple of hours I have Android 5.0 and so far everything is working fine :) Just for those who are not very tech savvies and need a little bit more detail for performing the installation, I'll give you a detailed step list for doin the upgrade. It is all based on Senhor method, that worked 100% with me, including gapps and all!

1) Download all necessary files, you can find them in the first link of this topic, posted by Senhor: link: https://drive.google.com/folderview?...DA&usp=sharing

2) Install nubia updater in your pc

3) Dial *#7678# in your phone and select both options, factory and adb. (Perform this check after every fmw update, and specially before installing gapps, at the final steps)

4) Open Nubia updater (is all in chinese, don't worry) and connect your phone through usb. If you see a green icon indicating phone connection, great you are connected. Otherwise install android adb drivers in your pc and restart everything.

5) Unzip 2.02 in a folder, untar 2.03 in a folder

6) Open Nubia updater, select 2.02 folder and click the button below. Update will start

7) In my case some reboots were performed and process stuck at 92%. I think that the program was asking in Chinese to turn on your phone manually (WITHOUT DISCONNECTING USB). I waited for more than 30 minutes thinking that it would pass 92 eventually...but it didn't. So at the end I turned on phone (STILL CONNECTED TO USB) and the the process finished!

8) Configure phone and repeat steps 6,7 but with 2.03 folder this time.

9) When you are at 2.03, connect to the phone via usb (like hard drive, media files transfer) and store update 2.05 in internal storage.

10) In phone setting, perform phone update from disk.

11) Voila, you are at the last revision. Now is time to install gapps. Extract twrp in your pc

12) Copy gapss .zip compressed file in internal storage of the phone

13) Open twrp application, is all in chinese. Press option 3, intro

14) You phone will reboot, in the menu change language to english (if you don't understand chinese of course)

15) Root your phone (necessary for gapps correctly), go to advance settings in your phone twrp menu, and other submenu that I dont remember (like tools or something), press Root

16) After that go to Install, and select gapss file that you stored before in the phone

17) After all this you reboot and you have fantastic Nubia Z7, Google phone with Android 5.0

18) If you find any problem with google apps, try to reboot a couple of times your phone, some settings may need reboot.

Thanks to Senhor for the process!

Enjoy!!
[ZTE Z7, Z7 Max, Z7 Mini] zdravke:
I'm not sure where you got a message when you had to reboot your phone manually, but I got somewhat similar experience:

1) update went all the way to 100/100 in Nubia updater

2) phone rebooted and a message in Chinese was displayed on the phone

3) I left the cable connected and pressed power button for around 5s

4) phone rebooted again, and again displayed the same message

5) I disconnected usb cable and performed power reset again

6) This time, a series of messages in chinese with grey background similar to "android upgrading" has been displayed at the bottom with progress bar

7) process finished successfully!

This happened to me with both 2.02 and 2.03 upgrades. I didn't perform step 3) from your list, as I don't have a microsim card, so the phone refused to dial.
[ZTE Z7, Z7 Max, Z7 Mini] carajillu:
Interesting point, the dial. But it is strange because it currently does not dial, it simply applies a system operation :S
[ZTE Z7, Z7 Max, Z7 Mini] zdravke:
True, that's why I thought I don't need a working sim. Maybe working sim is required for system operations as well?
[ZTE Z7, Z7 Max, Z7 Mini] zdravke:
This phone has probably the worst measured wifi performance I have seen - typically 3.6 Mbps! My Nexus 6 measures 50 Mbps flat! Very disappointing. I can feel it takes forever to update and download various apps from play store. I expected a lot more from a Chinese tech giant, instead it bottoms out right there with all other el cheapo chinese noname brands.
[ZTE Z7, Z7 Max, Z7 Mini] carajillu:
Are you performing the test in a reliable manner? For me the speed is correct....Maybe you have to configure something
[ZTE Z7, Z7 Max, Z7 Mini] zdravke:

[ZTE Z7, Z7 Max, Z7 Mini] zdravke:
I just noticed a star which I missed to dial in step 3) , so that explains it. But I managed to update the phone without dialing that code?

Anyway, I noticed that for sim1 to be recognized, phone needs to be rebooted. Sim2 is recognized as soon as it's inserted. Anyone noticed this?

Does anyone know how to change lockscreen wallpaper??
[ZTE Z7, Z7 Max, Z7 Mini] carajillu:
Regardin lockscreen wallpaper, you can change it if you use Nubia wallpapers. Using others like Google now launcher, or Nova does not give you the option.... Anyway, probably easy to configure with an app or something. I like the leopard ;)
