1. While device on, navigate to developer settings and turn on USB debug, then connect the device to the pc and open and ADB, and type in command "adb devices", at this point there should be messagebox that asks you if you trust this computer, tap remember and press ok
2. After that you can shut down your device, and when its completely off you need to boot into bootloader (also known as fastboot). To do this, hold power button + volume up button at the same time, when you feel a vibrate, let the power button go and keep holding volume up. Soon you should see android laying on its back.
3. Then open up adb and to see if you have succesfully connected, type in "fastboot devices", if you see something like "fastboot XXXXXXXXXXXXX" where X equals to random numbers, you are set. Now you need to move TWRP .img file you downloaded, to the same folder where adb.exe and fastboot.exe are located. Also you could rename the file to TWRP.img to make it simple. Then, type in "fastboot flash recovery TWRP.img" and now you should have TWRP installed.#CM
12.1 and GAPPS
CM 12.1: http://theflamingskull.com/zenfone2.html
Download latest CM 12.1 build for Z00D
Download x86, 5.1 gapps. You can decide the variant yourself, nano is recommended because it has everything not inluded in Play Store so you dont miss anything nor end up with unwanted bloat.
Move both files to your phone and boot into TWRP by first booting into bootloader and then choosing recovery mode with volume buttons and selecting with power button. In TWRP, Wipe>Factory Reset, then go back to main menu and Wipe>Advanced>Select system, dalvik/art cache, and cache. Now go back to main menu and press Install and then select the CM12.1 .zip. After thats done, flash the opengapps .zip file. After that do the same for SuperSU zip. After thats done too, you can press the "wipe dalvik/cache" button, and then you can go Reboot>System.
