HOW TO ROOT ASUS ZENFONE 2 LASER 5.5s (ZE550KL) MARSHMALLOW 6.0.1

Marshmallow_root_access

Thanks to Chainfire who developed Superuser app that we can use to grant us root access to our device so we can get rid of those bloatware apps pre-installed.

After the upgrade to Marshmallow and reverting back to Lollipop then going back to M trial and error steps, I also tried to root my upgraded M 6.0.1 version and finally came up with a solution since my root access was removed after the update.

If you miss out my post on how to install update via adb sideload you may check it out here.

Decide if you wish not to install custom recovery.img like TWRP to your device then you may try directly the "adb sideload" command to install the zip file SuperSu, just boot to recovery and select "apply update from ADB" before typing your "adb sideload" command.(Retested with Magisk.zip on a stock recovery but get installation abort error)

Flashing TWRP via adb

Since I prefer to have a custom recovery.img like TWRP which is quite handy to make a backup ROM that I can easily restore in case I encounter errors in the future so you may as well follow.

When you are in Marshmallow version you need to flash TWRP via adb, I had a separate tutorial found here on how to flash or just follow steps below.

***Download TWRP.img (here)

STEPS:

1. Just save the custom recovery.img(TWRP) under adb platform tools folder and you may opt to rename it to whatever name you want either to shorten the original name like recovery.img , TWRP.img vs the long name twrp-3.0.2-5-Z00L.img

2. Connect your device to PC then just open a command window and type (Shift+right click of mouse)

• adb reboot bootloader (hit enter key)

followed by

• fastboot flash recovery twrp-3.0.2-5-Z00L.img (hit enter key)

3. No need to disconnect but simply boot into recovery Power+vol down or type in

• fastboot boot twrp-3.0.2-5-Z00L.img (hit enter key)

Installing SuperSU via adb sideload

***Download SuperSu.zip (here)

STEPS:

1. Make sure you have save the SU_zip file in adb platform tools, now once you are in recovery (TWRP) mode I want you to go to advanced and select ADB sideload, then "swipe to start sideload" as you may skip the wipe dalvik cache/wipe cache.

ERROR ENCOUNTERED IF USING TWRP TO FLASH SUPERSU.ZIP FILE

For those who wish to try install SuperSU.zip via TWRP (INSTALL) then I wish you luck since I was not able to get good results but more of errors even tested one zip beta from shakalaca who tried to modify the zip file but ended up as corrupt file when using TWRP.

TWRP_flash_SuperSu_beta_fail

Same result when I flashed chainfire original SuperSu.zip and return an error of zip file being corrupt until I decided to use adb sideload that successfully installed SuperSu. Not sure if there is a bug in Marshmallow firmware that won't let the TWRP install the SuperSu.zip file but in Lollipop version there are no errors.

There's an updated SuperSu zip file from chainfire archive if you wish to download instead of the above old zip file. (here)

Summary:

Using TWRP recovery via adb sideload:

1. Download SuperSu zip file and move to adb platform tools folder (you may rename-optional)
2. Shift+Right click to open command window
3. Boot to recovery mode Power+Vol down and connect to PC

• click advance
• select adb sideload
• wipe cache/wipe dalvik cache (optional)
• swipe to start sideload

4. Type adb sideload (name of SuperSuzip).zip and hit the enter key(e.g. adb sideload SuperSU.zip)
5. Wait as it installs the update to your device
6. Reboot your device
7. Download root checker to test
