Fix Lenovo Zuk Z1 Network Issue-No Network
So many people are having network issue with their Lenovo Zuk Z1 phones.I found a simple trick to make it work. This error actually occurred due to Lenovo Zuk Z1’s frequency band which is incompatible with many networks.
I have tried a lot of workarounds like rebooting phone into safe mode,disabling aeroplane mode and restarting the phone.None of them actually worked.So i advice you to follow the steps mentioned below for your phone to run normally again.

First of all,you need to have a custom recovery installed in your phone.To do this you have to unlock your phones bootloader which will void your warranty.
Unlocking bootloader will erase your files.So please take a backup before proceeding. Its upto you and i am not responsible if you brick your phone.
If you have already unlocked your bootloader and have custom recovery installed skip to step 11.
1)Download and install fastboot drivers in your pc from here.
2)Go to phone Settings>enable ‘OEM unlocking’ under Developer options.If you don’t find developer options then, go to About Phone>Tap 7 times on build number.
2)Turn off your phone and go into bootloader mode by holding Volume Down +Power button together.
3)Once you are in bootloader mode, connect your phone to pc.

6)It is recommended to restart you phone.Type “fastboot reboot” in the command prompt and your phone will reboot.
7)Disconnect your phone from pc and setup your phone like selecting your language,logging into google etc., and go to bootloader mode again.

9)Open command prompt from the desktop by holding shift and then right click.
10)Connect your phone to pc and type “fastboot flash recovery twrp-3.0.2-0-Z1.img” in the command prompt.
10)Then turn your device off by holding the power button until it gets turned off.Now, go to recovery mode by holding Volume Up+Power button together.
