YiOS 5.1.1 for Nubia Z7 Max.


Rom was not made by me but found on Chinese forum here: http://www.tdbeta.cn/thread-258758-1-1.html

All credits go to lwanggg for making this rom.



  1. Enable Android Debug Bridge (ADB) in developer options on your phone
  2. Plug your phone to your computer
  3. Use commandline to reboot to bootloader: adb reboot bootloader
  4. Check that your device is properly detected with command: fastboot -i 0x19D2 devices
  5. Flash recovery with command: fastboot -i 0x19D2 flash recovery recovery.img



  1. Make sure that your phone is powered on and plug it to your computer
  2. Put the rom (yios-5.1.1-beta-20150611-nx505j.zip) and gapps (gapps.zip) in your phone's internal memory
  3. Use commandline to reboot to recovery: adb reboot recovery
  4. Go to Wipe > Advanced wipe
  5. Tick Cache, Dalvik cache, Data and System boxes
  6. Swipe your finger on the bottom slider to wipe
  7. Go to Install and install yios-5.1.1-beta-20150611-nx505j.zip
  8. Repeat step 7 with gapps.zip
  9. Return to TWRP main menu and choose Reboot > System
  10. Rom will boot. Remember that first boot takes a long time


To those who don't have multilanguage: just use "MoreLocale 2" from Play Store to switch languages. It works perfectly for me.

      I don't have that problem. In fact, this is probably the most stable ROM I've used on the Z7 Max, even better than the original Kitkat 4.4.2 Nubia OS ROMs. It even does 4G without any problems.

      The only drawbacks I can find are limited language options (English & Chinese only) and lack of some configuration options (for example, I can't set the date format to a custom one, or set the internal weather widget to degrees Celsius).

      It's also missing the infrared app.

      Other than that, it looks like a great ROM.

      It may be because you updated from previous YiOS version, which was multilanguage. Your settings weren't touched then.


      To those who don't have multilanguage: just use "MoreLocale 2" from Play Store to switch languages. It works perfectly for me.

    everything works fine, but it doesn't recognize my sim…its as if there is no sim inside…i can't activate it from settings…

    Does anyone what might have happened?

      Maybe you have a wrong modem version or wrong firmware in /persist partition. You should reflash official firmware clean with the Nubia Updater Tool (flash a custom version based on original firmware before, it's needed to do it).

    Are there any differences between this ROM and CM12.1 yirom?

      CM12.1 Yirom is two months old. This one is more recent and has all new CM options. It's also better optimized.
