Install Android 9.0 Pie GSI on Moto G5 Plus (Windows/Mac/Linux)​​​Obligatory Warning: This guide and ROM assumes you know the fundamentals of fastboot, flashing TWRP, and running a flash all. Your warranty is voided because of the unlocked bootloader. This is a Third Party ROM. Things may not work as expected compared to stock (for better or for worse).
Warning 2: If you can't do fastboot commands, do a flash all, root your device or flash TWRP/ROM, please do not ask for help here. If you cannot flash all back to stock, please stay stock for everyone's sake.
Warning 3: If coming from stock, backup your persist and efs partitions. If you already have a backup of those partitions, upload them to Google drive. If you dont have a backup of those partitions yet, do so now. Search the guides section and you will find a tutorial.
Warning 4: You might loose all your data. Make sure to backup your data.

You cant go back to u3 bootloader once it is updated to u4.....
Its just same as the knox thing you cant do anything here
U3 bootloader was version of bootloader which ised to come with oreo and pie upto april security patch.
And the may security patch upgrades your bootloader
Hence you cant downgrade beyond may security patchh..

[ZE620KL/Android 9][TREBLE] COMPLETE GUIDE: Unlocking, Rooting & Flash GSI + Fixes

[ZE620KL/Android 9][TREBLE] COMPLETE GUIDE: Unlocking, Rooting & Flash GSI + Fixes
Unlocking bootloader to Flashing GSI (Asus Zenfone 5 [ZE620KL] / Android 9.0)
Code:
/*

About :
The last guide could leads to soft brick, as the instructions were not clear nor the files not supported for Android 9.0.
Here is a complete guide with TWRP 3.3.0 for Android 9.0, clear instructions and multiple fixes for GSI.
It has been tested on stock version v16.0615.1903.92.​
Requirements :
- A stock version V16.0610.XXXX.XX or higher
- A phone on Android 9.0 (not 8.0!)
- A fully working USB cable
- Latest ADB / Fastboot drivers
- Bootloader unlocker (download latest from Asus website or from here)
- TWRP 3.3.0 image
- Android9EncryptionDisablerZE620KL.zip
- Magisk v19.3​
Instructions :
Unlocking Bootloader
1. Backup all your important data.
2. Install the bootloader unlocker APK, and follow the steps. You will loss your warranty here, and it will factory reset your data
3. If there is any issue here, go into your stock recovery (volume down + power button) and factory reset.​
Installing TWRP
4. Shutdown your device & boot in fastboot mode using volume up + power button.
5. Check that the connection between your device and your computer by typing this in your command line :
Code:
fastboot devices
6. Flash TWRP recovery using :
Code:
fastboot flash recovery <twrp_name>.img
7. Now reboot in recovery mode using :
Code:
fastboot oem reboot-recovery
8. In TWRP, select Wipe > Format Data > enter "yes" and confirm
9. Return to the main menu, select Reboot > Recovery
10. Do 8. & 9. and again
11. Using TWRP or ADB, install Android9EncryptionDisablerZE620KL.zip (on TWRP, go into Install > find Android9EncryptionDisablerZE620KL.zip > Install zip)
If everything has gone successfully, you now have a custom recovery.
As for some GSIs, a patched boot partition may cause bootloop, you should try installing Magisk after installing the GSI. If you want to keep your stock ROM, go directly to "Magisk Installation" section.​Installing a GSI
This step may vary depending on the different GSIs distribution. I assume you install Havoc OS v2.7 GSI which actually works on this device.
1. Backup all your important data using TWRP backup.
2. Select the arm64-aonly GSI image you want, and move it on your external SD.
3. Wipe Data, Dalvik, and Cache.
4. Go back in the main menu of TWRP, and reboot to recovery.
5. Remove Magisk if it was previously installed, by using its uninstaller script.
6. Flash the GSI to system partition.
7. Boot and perform a factory reset.​
Installing Magisk
1. Add the Magisk zip archive to your external storage.
2. Boot into TWRP recovery, and install the zip.
3. Enjoy!​
Bug fixes:
Insufficient storage in the system partition to flash GApps : Download your OpenGApps archive on your external SD, and use MagicGApps 2018.9.23 to install GApps.
Auto-Brightness doesn't work: Download framework-res__auto_generated_rro.apk from here.
Using a root explorer or command-line, push the APK to /vendor/overlay.
Then run the following command in a rooted terminal or ADB shell:
Code:
chcon u:object_r:vendor_overlay_file:s0 /vendor/overlay;chcon u:object_r:vendor_overlay_file:s0 /vendor/overlay/framework-res__auto_generated_rro.apk
My camera doesn't work well (green tint on face camera) and/or the app doesn't boot: If Asus Camera doesn't launch on your GSI, you should probably edit your /system/build.prob file.
You need to edit ro.product.model, ro.product.brand, ro.product.name, ro.product.device, ro.product.manufacturer & ro.build.product properties to be:
Code:
ro.product.model=ASUS_X00QD
ro.product.brand=asus
ro.product.name=WW_Phone
ro.product.device=ASUS_X00QD
ro.product.manufacturer=asus
ro.build.product=ZE620KL
You can instead use Google Camera mod (port from Arnova8G2 & modded by 5Z community, thanks to them!), which works well (edit: there is a bug on HavocOS, we can't access settings).​Bonus:
- You can reinstall DTS Headphone:X here.
- For booting your kernel in Permissive mode, check here

(We will continue to update & help here though.)
Many thanks to all of the Zenfone 5 community (particularly Emincan, Pandolfi and Lmajkej),
Phhusson & Erfan for their works on GSI, and Shakalaca for its work on TWRP 3.3.0!​

On HavocOS v2.8 GSI (13-08-2019):
It works:
- Almost anything
- Adaptive Brightness (after manual fix)
- Notch overlay
- DTS Headphone X (after manual installation)
- NFC
- Face unlock
- Stock camera (after manual fix)
- Magisk
- SDcard access
It doesn't works:
- VoLTE / VoWifi
- Google Camera settings
- External speaker amplifier (NXP amp)
- APT-X / APT-X HD bluetooth
- Low microphone in normal use
- No microphone in calls (only headphone microphone works)

GCam settings
But my google camera keep crashing when I want to go into camera settings

Hi thanks for this tutorial, this is my first time rooting my phone. I'm encountering a problem with my sd card after installing havoc os, everytime i try to move, save or any write functionality i do to my sd card, it always says the android version isn't compatible. I could still see my files from my sd, but everytime it asks permission it always say this

Same issue here. I will update the thread when I will find a more working GCam port (perhaps, this GCam port works well on ZenUI)

It's a known issue, the GSI maintainer @vince31fr is working on it. I don't have it, but I can advice you to use Solid File Manager, which works like a charm on my device.

"- No microphone in calls (only headphone microphone works)"
Funny... I'm on stock latest firmware and I have this issue, so I thought I try something new, and this has that issue. It can't be a coincidence. Something is ****ed up with this device.

Wonder if this will work for the Zenfone 5 Lite (or 5Q)? I wanna root my 5Q so bad haha

Thanks for the great instructions! Steps 1 through 11 worked perfectly for me, then I installed LineageOS (lineage-17.0-20191231-UNOFFICIAL-treble_arm64_avN.img) and it works properly. Then when I go back to TWRP and install Magisk v20.1 it reboots into an endless Lineage bootup logo animation (not boot loop). I can get an adb shell, but now also the external SD card has become invisible. Any suggestions?
UPDATE: I switched over to the patched Magisk version from PHH (https://forum.xda-developers.com/zenfone-5/general/ze620kl-add-support-to-evey-android-9-t3966918) and everything works perfectly now!

Hi!! I thanks for these instructions you gave. I know this post is a bit older. But is the only one I think could help me.
I got an ZE620KL and I'm trying to root this device. I have some experience in unlocking bootloader and rooting devices. But this one... Is giving me a lot of work. Researching in a lot of forums and websites I tried a lot of things with no success. In theory, is just install the official apk provided by ASUS and run the application. But the app doesn't work for a long time as I researched (error accusing network problem). I tried unlock via fastboot commands but I always got stucked by "remote: permission denied" even with latest drivers and ADB Fastboot installed. And yes... I let my device with no one security feature enabled and didn't worked. I tried everything even after wiped data / cache and factory reset and no progress.
In my researches, I realized something about 'oem unlock'. It appears to be the key to solve this. And I guess the tool to work with this is the damn unlock tool from ASUS which don't work! Also, I've heard about workaround with Magisk by flashing a custom recovery to achieve the root. Magisk no longer supports zip files to flash. Only '.img' and '.tar' files. I'd like to find some light here... I don't know what to do. I appreciate any help!

Hello do I need to flash Android9EncryptionDisablerZE620KL.zip if Im gonna flash a non-GSI custom ROM? Or its only for GSI Treble ROM?

Inject TWRP after install:
Automatically injects current installed TWRP into the boot image of the ROM/zip youre installing when ticked
Broken:
LGs encryption on Stock
encryption on other ROMs(?)
How to flash ROMs (PRE metadata encryption):
Reboot to TWRP
Make a backup
Install -> select the ROM zip -> tick Inject TWRP -> Swipe for install
wait... ROM will be installed into the NON ACTIVE slot (if youre on a, it will be installed to b, and vice versa)
Reboot system
for gapps, magisk or other mods:
DO NOT REBOOT TO SYSTEM from last step
Go back -> Reboot -> select the non active slot (to where the rom got installed to) -> select recovery
Install gapps, magisk, and whatever else you want
Reboot system
How to initially flash ROMs (metadata encryption):

Warnings:
Updating a ROM means reflashing the mods you flashed too (e.g. Gapps), addon.d doesnt work properly
Be aware of the slot you are currently on
If youre flashing a ROM to a slot, make sure you also have the required firmware (abl, modem, and so on) in that slot
Infos:
System image/Vendor image and system/vendor are redundant, the image variants are direct copies of the partition (and also their size) while the others are "simply" files copied and repacked
How to use decrypted stock by @Xsavi : https://forum.xda-developers.com/lg-v40/how-to/guide-twrp-data-access-stock-t3970149
Metadata encryption TWRP requires 10 firmware to use properly, no guarantee for it to work on Pie firmware!

Hmm interesting I see ?

Wow. The V40 got TWRP too. Awesome.

Wooo new twrp! Great work Markus!

How hard would it be to get this working on the V35? I can get it to install and boot into recovery, but it does not register touch input.

Well, having a big issue. I installed TWRP, Install custom rom w/ twrp inject, reboot menu, selected the slot where the rom, restarted, no TWRP, No root, but custom rom and now it comes up as unknown in LG UP so I can try to fix it. I think its mostly a brick since I can't do anything. No Fastboot either because im in slot b and cant switch because no root or fastboot.

did you have pie firmware also in the slot where you installed LOS to?
otherwise.... nothing is ever really a brick, you still have 9008 mode as last option

Fixed. Case of the bad drivers. LGUP didn't wanna read so I went to a different computer. Read it through LGUP, flashed Stock, rebooted to recovery, TWRP popped up.

How do the two slots work? I thought that these were for current ROM in one and then new ROM in the other, alternating with each ROM update. Why is one for the ROM and the other holding system partition additions? I would expect gapps to integrate into both A and B sides at once on top of each ROM...
Is there documentation on this?

So I'm bootloader unlocked, rooted on pie and cannot access fastboot. How do I go about installing twrp?
EDIT: tried different USB-C cables and one worked like a charm.

Nothing, phone just reboots like nothing is there. neither the button combo nor the "adb reboot bootloader" command works.

So I got on of the US models unlocked bootloader Verizon I got fastboot can I flash this one to my 405ua verizon?
In fastboot i see Judypn But I believe they flashed a open Korean on mine Im trying to get back to US firmware twrp and magisk if at all possible

Well I can confirms this works for pie on a 405ua unlocked bootloader...Nice work mate...
After reading through a bit and playing around. I got recovery installed on ramdisk recovery. Got out of my bootloop by fastboot flashing stock boot img from my current firmware. I did notice slot b I still have stock recovery which helped getting out of the failed encryption loop. And I also have download mode there.

What drivers did you use? I can't get my LGUP to recognize the device. I'm trying to flash stock back to a working copy of Lineage 16 with twrp.

Broken:
LGs encryption on Stock
encryption on other ROMs(?)
exFat for external SDs
Does this mean just within recovery or within Pie?.... The exFat part, that is

Both, as pie uses the same kernel as TWRP when booted

I have the mentioned model and I tried some things on it. Sharing my experience with you as a guide.
Backup anything you need out of the phone before proceeding as the next steps erases the phone data.
You need a windows machine to follow this guide.
My experience with
Bootloader Unlocking [Source]
It has a relatively simple bootloader unlocking procedure.
To unlock bootloader, go to developer options and enable OEM Unlocking. Then reboot into download mode. Hold down the vol up key for oem unlocking. Quickly press the volume up button as soon as the next screen comes up. If done right, it should erase userdata automatically on the next boot. After erase, it will reboot. setup the phone with default options and go to developer options again. That's it, bootloader unlocked.

Root
Summary: After rooting, phone didn't recognize IMEI anymore, so, no network. Phone storage was reduced down to 8 gb instead of 32gb.
But nevertheless, root worked.

By the way, the signal problem has been reported on other occasions.
It seems to be a problem on this Mediatek SoC
