[Root] Zenfone 2 Official Android 6.0 Root + Xposed and Downgrade

[samcjtsai]

**WARNING** You need to have background knowledge of adb, fastboot, twrp, sideload.. before you can go on with this thread.
1. All credits go to @shakalaca. If you like his work, please make him a small donation for encouragement.
2. This is a systemless root. Yet you need to unlook Lollipop before upgrading to Marshmallow.
3. Flashing the attached SuperSU file modifies stock boot.img. In case you receive an OTA file later, do
**REMEMBER to FLASH BACK TO STOCK Android 6.0 BOOT.IMG** to unroot before upgrading to official Android 6.0.

Root:
1. Unlock your device in Lollipop, then upgrade to Android 6.0
2. Once you are in Android 6.0, fire the following command to boot twrp. <twrp.img> is the twrp recovery file. This TWRP is recommended.

adb reboot-bootloader
fastboot boot <twrp.img>

3. adb sideload the attached SuperSu file in twrp. /OR install the SuperSU in twrp if you saved it in device storage.
4. reboot system. You will see a warning screen saying "Your device has failed Verification". Ignored it and wait for the reboot.
5. Done

Unroot:
Just flash back stock boot.img

Xposed:
1.Flash the attached Xposed file from twrp.
2.use Material Design Xposed Installer: Download Xposed Installer here

Downgrade to Lollipop:
In case you need to downgrade to Lollipop, follow the instructions with care. Do it at your risk.
Refer to Asus Zentalk Forum and grab the required files from there.

fastboot flash token bom-token.bin 
fastboot flash ifwi ifwi_ann_a0-mofd_v1-ze551ml.bin
fastboot flash fastboot droidboot.img
fastboot flash splashscreen splashscreen_ze551ml.img
fastboot reboot-bootloader

Now you are back in Lollipop. You can flash back stock recovery(.184 recommended), wipe the device(cache/userdata/system) and then sideload back stock LP or MM as you wish. OR, you can flash custom recovery/boot/system.img start from here.

Good luck!

I just need root on 6.0.1. Is this going to achieve that?

It does work, but YMMV, my phone is one of the few that works completely with the beta software. But before running fastboot cmd in adb. Use adb reboot recovery, then fastboot cmd. Phone will reboot twice after sideload of SU.

1. All credits go to @shakalaca and I just try to recap his threads posted in Taiwan Asus Zentalk forum. Although this is reported working in the forum but, as usual, do it at your risk and I won't be able to answer your questions.
2. Android 6.0 is still not unlocked. Device will be locked once you upgrade to 6.0
3. You can downgrade to Lollipop and unlock again.
4. The following SuperSU file contains a modified boot.img. In case you receive an OTA file later, do
**REMEMBER to FLASH BACK TO STOCK Android 6.0 BOOT.IMG** before upgrading to official Android 6.0.

Root:
1. Make sure your zenfone 2 is unlocked before upgrading to Android 6.0 from Lollipop.
2. Once you are in Android 6.0, fire the following command to boot twrp. <twrp.img> is the twrp recovery file. Version 2.8.7.7 is recommended.

fastboot boot <twrp.img>

3. adb sideload the attached SuperSu file in twrp.
4. reboot system. You will see a warning screen saying "Your device has failed Verification". Ignored it and wait for the reboot.
5. Done

Xposed:
1.Flash the attached Xposed file from twrp.
2.use Material Design Xposed Installer: link

Downgrade to Lollipop:
Refer to this and get the files from the links. Note the first commnad line is the revised one by @shakalaca and it should work.

fastboot flash token bom-token.bin 
fastboot flash ifwi ifwi_ann_a0-mofd_v1-ze551ml.bin
fastboot flash fastboot droidboot.img
fastboot flash splashscreen splashscreen_ze551ml.img

Works like a charm !! Thanks !!

Assuming that everyone knows how to use adb and its commands

1: Well first make sure adb and drivers are on your pc.
2: Plug phone in make sure USB debugging is on
3: In adb cmd window type "adb devices" to make sure phone is recognized, if so proceed
4: type "adb reboot recovery" phone should boot into recovery with android robot on screen
5: Then type "fastboot boot <twrp.img>" twrp.img is whatever your file is named
6: phone will boot into recovery, go to adb sideload in recovery
7: type "adb sideload <SU.zip>" or whatever you have it named
8: After it's done loading reboot from recovery, it will reboot twice and the screen will say as per OP
9: After phone optimizes...enjoy root.

This is for advanced users

He's using whats called "tethered TWRP". It's basically running twrp on your phone from your computer instead of actually installing it (which would require unlocking).

Thank You for explaining that to me, appreciated!

 

[euthic]

To downgrade to Lollipop, is it possible to just use AsusFlashToolInstaller and flash raw firmware? Any harms by doing that?
Thank you in advance.

You need to adb sideload all LP .184 images first then use Asus FlashTool to flash RAW Firmware.

Maybe I'm doing something wrong but my phone isn't recognised when trying to flash twrp from the dead bot before recovery? Just says waiting for device. Already checked device manager as well

Guess your ZF2 is not unlocked in LP first, so that you can't see twrp booting. Since you are in Android 6.0 now, try to downgrade to LP, Unlock it, upgrade to 6.0 and then root.
