This root requires replacing stock recovery with patched magisk init, which will then boot system with magisk support. This means that currently, TWRP or stock recovery and magisk can't exist simultaneously. Also, in order to boot with root, you will NEED to hold down VOLUME UP as the phone is rebooting or booting until the "device is booting" text is displayed. This tells the phone to boot into recovery, which is taken over by magisk init and booted into system with root. Failure to do this will result in the phone booting WITHOUT root or magisk.
I've gone ahead and patched the recovery_ramdisk for EVR-AL00 and EVR-L29.
What is needed:
A bit of know-how
Step 1: You MUST be bootloader unlocked
-Start by downloading the relevant recovery ramdisk for your variant the AND magisk manager below
-Install the magisk manager
-Copy the recovery ramdisk to a folder with fastboot. Those with environment set up for adb/fastboot can ignore this step.
-Reboot your device to the bootloader. This is accomplished easiest with the adb reboot bootloader command. If you would like to gracefully put the device in bootloader mode, simply power off the device, remove all USB cables from it, but make sure one is plugged into your PC. Once the device is fully powered off, hold down the volume-DOWN key and then press and hold the power button and IMMEDIATELY plug the USB-C cable into the phone.
-Once the device is in bootloader and connected to the PC, run the command "fastboot flash recovery_ramdisk recovery_ramdiskMagiskVARIANT" with VARIANT being whatever ramdisk you downloaded. For example with AL00 you would input "fastboot flash recovery_ramdisk recovery_ramdiskMagiskAL00.img"
-Run the command "fastboot reboot" and immediately disconnect the USB-C cable from the phone. At this point you will want to hold down VOLUME-UP until the "device is booting" message is displayed.
-Once the system is booted, open magisk manager and profit.
