Experimental TWRP for the Asus Zenfone 5z

This is a very experimental version of TWRP. Use at your own risk.
I am posting this now because it seems there is no other development and perhaps this can stimulate development for the 5z.

Due to lack of time (full time job, wife, kids and a master), i cant promise any quick development.
ROM development is stuck due to the fact that i cant get a system image booting at the moment.

Flashing TWRP:
- Bootloader needs to be unlocked
- You need adb and fastboot
- Boot into bootloader (from the stock rom use adb reboot bootloader)
- Check the current active slot, change the slot to the other slot (if current active slot = a then use b. If b, then use a)
- Switch slot by using fastboot set_active <a|b>
- Just to be sure use fastboot reboot bootloader and check if the slot has changed.
- Download link of the boot image: https://www.androidfilehost.com/?fid=1322778262903990756
- Flash the boot image by using fastboot flash boot boot.img
- Select recovery from bootloader

By booting back to stock, boot into bootloader and use fastboot set_active <a|b> to switch back the slot and reboot.

Did you already have a look at/try Force_Encryption_Disabler_ZE620KL.ZIP from that taiwanese post by shakalaca? Or is that something worth trying?

As far as I understand it's just changing forceencrypt to encrytable in the vendor fstab.

Would still need to be formatted. But will do that as soon as I get some omnirom booting.

TWRP was still experimental and i don't have the time to continue development at the moment. To prevent potential bricks I have decided to take it down.

I see, it's a good decision. I hope you have received your device and maybe in the future you can make a fully working recovery. Thank you for your effort.
