[Zuk Z1 Q&A, Help & Troubleshooting] platontw:
Hello ,

My 1st Thread so , sorry for any mistakes ! :D

I had ZUK Z1 with ZUI OS and I was trying to flash Cyanogen OS in fastboot mode which is most usual way but whatever program I was trying , it didn't recognize the device .

I did installed a lot of drivers , ZUK drivers , Google, Samsung , ADB etc , but had the same results . Of course I enabled all the features, Android Debugging , OEM Unlock etc .

So I tried to ROOT it .

I used King Root for Windows , it started the Root process but when finished it gave negative results , so No Root .

I am not a Developer , just a user who search for solutions .

Now , when I was trying to Root the phone with King Root , the process starts from ''00%'' in a circle and when it goes to ''50-51%'' , the program Reboot the Phone and it automatically installs and OPEN the TWRP Recovery (2.8.7.0) and after some seconds (about 5-10 sec ), it reboot the phone from TWRP Recovery in OS again , with message that it didn't Root the phone .

I tried this several times but had the same results .

So , what I did next was , Run the King Root program again , and when the phone Reboot to TWRP Recovery , I unplugged the USB cable and I had the new TWRP Recovery which I could install the Cyanogen OS , SuperSU (2.46) .

I posted this thread and hope is useful , I will post it step by step below .

Of course I am not responsible for any warranty , damage , bricking the phone and you should continue at your own risk .

1 .

Download drivers for phone ( I used Windows 10) , some drivers here

2.

Install drivers ,

Enable in Developer Options ( press fast 7 times the Build in About phone to show ) in phone the Android Debugging and in Options , Security enable ''Unknown Sources'' .

3.

Download King Root for Windows (it is all almost in Chinese but it has instructions what to press or if you find it in English the better)

http://kingroot-pc.en.uptodown.com/

and install it (PC)

4. Download Cyanogen OS from Cyanogen site :

https://cyngn.com/support (ZUK Z1 : cm-12.1-YOG4PAS60J-ham-signed-61f79ce687.zip)

and SuperSU 2.46

5.

Copy Cyanogen OS and SuperSU in phone (not to any folder so you can find it quickly)

6.

Run King Root , Connect USB cable from phone to PC and wait a few seconds until the program finds the phone .

Then Press ROOT and wait maybe several minutes UNTIL THE PROCESS REACH 50-51% ,

Then the PHONE WILL REBOOT and ENTER TWRP RECOVERY - IMMEDIATELY UNPLUG the PHONE and then VOILA !

You Can flash then the SuperSU and Cyanogen OS .

NOTE : I didn't had enough time to verify if the Recovery it will remain (you can enable it from the settings fix permissions) once you install the cyanogen os or if it will change to ZUK recovery or Cyanogen Recovery.

The End

05/04/2016 - ROOT ZUK Z1 VERY EASY .

I found another way to ROOT the device .... it doesn't need computer at all ... just the KING ROOT APK .

Follow this link , Download the latest KING ROOT v 4.8.5 to your phone or copy the apk from PC to phone .

http://www.appsandroidapk.com/tools/kingroot/

Once you download this APK , install it , RUN , scroll down to the button which says ''TRY IT"" for purify system and press it .

After a few seconds , it will show a message , Root access unavailable and below a button ''Try to ROOT'' , press it and after a few seconds or minute and you will have ROOT on your ZUK Z1 .

OK ... NOW ... After the ROOT , of course you can't keep ZUI OS and you want Cyanogen OS ..... BUT ... You must install another RECOVERY from the ZUK Recovery .... Download from playstore apps like FLASHIFY (Christian Göllner ) , TWRP MANAGER ( Jmz Software ) etc .. which are GREAT APPS ... and install DIRECTLY from the app the recovery you want ....
