3) Rooting | Flashing | Applying OTA

3.1) Rooting Zenfone 2

NOTE:

If you root via METHOD 1 you can update SuperSu app as well as update binaries butPLEASE DON'T apply any OTA update as the phone WILL GET STUCK IN A BOOTLOOP...Manually flash the firmware via adb...
If you root via METHOD 2 you CAN UPDATE VIA OTA/NO BOOTLOOPS BUT YOU HAVE TO UNROOT FIRST BEFORE APPLYING OTAIf you root via METHOD 3 you CAN UPDATE VIA OTA/NO BOOTLOOPS AND UN-ROOTING BEFORE APPLYING ANY OTA IS NOT NECESSARY.

Method 1 (PRE-ROOTED SYSTEM.IMG) : 

Credit goes to: shakalaca , keepfishes

First things first: (get this straight, don't download the wrong firmware and flash the wrong thing)
ZE550ML = Z008
ZE551ML = Z00A

Files Needed:

1. Drivers for Asus Zenfone 2 installed on PC
2. ADB installed on your PC (https://drive.google.com/file/d/0B0M...ew?usp=sharing)
3. Flash Tools (http://forum.xda-developers.com/atta...3&d=1431011927)
4. Pre-rooted system.img and recovery (https://mega.co.nz/#F!k4MHiAgL!dVuOKeH3eokcwPSNI79ffw) (Download the correct firmware according to your phone)
5. WinRar

Steps:

1. Download the pre-rooted system.img folder (Download the correct firmware according to your phone ZE550ML = Z008 , ZE551ML = Z00A )
2. Download and run WinRAR . Click on the '.zip' part of the system.img file. You will see that WinRAR puts all the parts together and offers you an option to extract the one big system.img. Go ahead and extract it to the folder the other parts of the ROM are in.
3. Unzip the FlashTools.zip and copy the following 4 downloaded files and paste it into extracted flashtools folder:
   1. boot.img (~ 11MB)
   2. droidboot.img (~ 13MB)
   3. recovery.img (~ 11MB)
   4. system.img (~ 2GB)
4. Disconnect your phone from PC/Laptop.. Power it off. Once it is off, hold down the volume up button and hold on to the power button until the phone vibrates. After the vibration stops, release the power button and continue pressing the volume up button until the green Android robot appears. You should see a blue line below saying "Waiting Fastboot command"
5. Now connect your phone via USB to your computer.
6. At the flashtools folder press Shift + Right Click.. Then select "Open command here"...
7. Copy and paste the following commands in the command prompt window (line by line) and press enter after each line. WAIT for the process to complete before copying and pasting the next line:
   Code:

   fastboot flash  fastboot  droidboot.img
   fastboot flash recovery recovery.img
   fastboot flash boot boot.img
   fastboot flash system system.img

8. The last step will take quite a while before it returns to the blinking cursor. Once it does, it's done and you can plug out the USB and press the power button, reboot your phone and when it starts up, your phone is ROOTED! You should see a # sign in the status bar

Method 2 (ROOTING VIA TEMPORARY CWM): 

Credit goes to: @29y6145 , social-design-concepts , Chinaphonearena

NOTE: This is a TEMPORARY CWM with the primary purpose of INJECTING SuperSU onto your Asus Zenfone 2. It doesn't permanently replace recovery and YOU CAN UPDATE VIA OTA USING THIS METHOD BUT PLEASE UNROOT FIRST BEFORE APPLYING ANY OTA...

3. Copy SuperSU.zip to the base of your SD card

6. Run 'cai_dat_CWM.bat' from the CWM package
7. In the black command window that opens, type ACCEPT
8. Type T4
9. Phone will reboot into fastboot and you'll see commands being issued from the PC cmd window copying the temporary recovery
10. You may see some funked up images on your display for a bit. Remove the USB cable and within 30 seconds should then see it booted into CWM
11. Select install update
12. Navigate to SuperSU.zip and install
