[GUIDE] Install the COMBO ROM Android L on the Nubia Z7 Max

March 7 2023

With this guide I will show you how to install on yours Nubia Z7 Max la COMBO ROM Android L, a custom ROM in Italian based on the firmware Stock 3.08 UI 2.9 released by Nubia. Although the stock firmware is still a beta version, the ROM in question can be used at the 100%, thanks to the great work done by the users of the forum Androidiani.com BB72 e Cuoco92 to whom all credit goes.

Before commencing, it is necessary to remember that neither I nor the entire staff of Smartylife.net take responsibility for any damage to your terminal, so do these operations solely at your own risk and risk.

Here's a brief overview of what the Android COMBO ROM is offering.

:

- GAPPs Installed

- ROOT

- Added some useful apps

- Add Italian language (and multi-language support) in the framework

- Advanced Translation but Not Total (Thanks to mrkaaco for Kitkat used translations)

- Removed Cineserie

- Graphic changes

- Other…

Bugs

These bugs are also included in the stock:

Even though the two SIMs work perfectly, the network signal of the two indicators is the same for both SIMs. So it's a visual bug that virtually lets you see the signal intensity of a single SIM.
Opening Maps does not display the GPS icon on the status bar even though the GPS works fine and is a bomb as usual. The icon is displayed correctly in programs such as GPS test, etc.
You can not disable one of the 2 SIMs.

Download Link ROM COMBO:

Well, now we can start!

WARNING
IT IS COMPULSORY TO SWITCH TO LOLLIPOP 2.13 BEFORE INSTALLING THE COMBO ROM 3.08 BETA. IT IS NOT POSSIBLE TO INSTALL THE ROM DIRECTLY ON THE KITKAT

INSTALLATION

Install the Nubia 2.13 Lollipop by following this guide: it's complete and very detailed, and you'll find the links for the various downloads inside. Read it all carefully. If downloading the Nubia Tool is slow then use this link.
Install the recovery TWRP 2.8.5.0 following the same guide.
Copy the COMBO ROM zip in the cellphone.
Enter recovery: keep the button pressed while the phone is switched off + volume up.
Push on Wipe and subsequently on Advanced.
Select Wipe Data/Wipe Cache/Wipe Dalvik Cache/Wipe System and swipe.
Go back and select install.
Select the ROM zip and make the flash swipe again.
Press on reboot.

The first start is long, you have to wait a bit.

TOOL NUBIA USE MAY BE LOST TO THE LOSS OF MIME, in case you should follow the instructions in the link above.

A PURPOSE OF INDISPENSABLE RULES that if you do not respect bring to the brick certain:

Once you have installed the Nubia Android ROM L DO NOT RESTORE NO BACKUP KITKAT / CM / etc DO NOT ABSOLUTELY FLASH OTHER ROMES (KK, CM11 / 12, etc) unless you are certain that 100% will support the new Lollipop partition.
The ONLY and ONLY way to go back to the pre-Lollipop situation is to resume the procedure with the Nubia Tool by installing the KK 1.64 following the link above but selecting KitKat instead of Lollipop.
After the 2 step you can safely restore Kitand's nandroid backup (old partition). Unfortunately after the 2 step you will have lost the breakdown (if it was done) and then you will get 2.5 GB for apps. If you want to resize it you will have to resume the PARTIALING procedure.

If you've done everything to perfection at this point, you should not have any problems, but if you do not hesitate to ask. I leave you link to the official thread that you can keep in mind both for future updates and for the great support offered.
