[Guide] Install Android Pie 9.0 (via Semi-GSI Version)

[Im_Mattgame]

This guide will show you how to install Android 9.0 Pie using the (semi) Generic System Image built using the official release.

What is project treble?
I would suggest checking out Android Authority's Gary explains video which goes quite well into depth.

How is it incorporated into this guide?
Well as you read from the title, we will be using a Semi-GSI, meaning we are using a ROM made for the OP5 (in this case the Mokee ROM) underneath and the GSI as the "frontend".

Download Section

• Latest OxyenOS version [Required]
• Latest Mokee Rom Nightly [Required]
• NoVerity (Encryption Disabler) [Required]
• PR1 - Semi-GSI [Required]
• Post GSI - 1 [Required]
• Post GSI - 2 [Required]
• Post GSI - 3 [Required]
• Working Google Play Services apk [Required for stability]
• Working Google Camera apk [Assuming you need a camera]
• Camera Fix zip [Assuming you need a working camera ?]
• Lag Fix(Inside this folder, called DP5 lag fix)
• Redflare Kernel (Latest "Treble" build) [Highly recommended for stability]

[0]Download everything above.

[1]MAKE SURE YOU ARE NOT ENCRYPTED
- If you are: Wipe Data
- If you aren't: Well, it's always better to start clean, Wipe Data

[2] Flash the latest OOS firmware

[3]Flash the Latest Mokee Nightly ROM

[4]Flash the good old NoVerity.

[4]Boot up the System

[5]Vaguely setup the phone, I'd suggest skipping the network connection process, just let the phone think you're called John Smith, it's not that important I swear ?

[6]Reboot back to Recovery

[7]Now the fun part, in TWRP > Install > Install Image (I too wondered when I would ever use it again) > Install the extracted image from P-PR1-sGSI-Aonly.zip

[8] MOUNT VENDOR, don't forget!
Goto Mount > Check "Vendor"

[9] Install all the Post files you downloaded (1, 2 and 3)

[10] Reboot to system

[11]Now the ROM is booted, however it is not yet ready for daily use. I invite you to reboot back to recovery.

[12]Using the Advanced > File Manager, move the Google Play Services apk you downloaded from above to system/priv-app, find the old one and replace it with the new one

[13]Again using the file manager, move the Google Camera APK to /system/priv-app

[14]Flash the Camera Zip fix

[15]Flash the Lag Fix

[16](Optional but highly recommended)) Flash latest Redflare Kernel

A lot of people have already been doing this for a while tbh, since the developer previews with the DP/PR roms here. There's even guides on YouTube for it.

 

[Pho3nX]

It's not AOSP Pie, it's S-GSI rom ported from Google Pixel DP/PR releases. And like said djsubstrain a lot of guides has been posted in the original topic [ROM][P][PORTED][semi-GSI] Android P Developer Preview

.
\09/ Normally, system boot fine, but you will encounter a Setup Wizard problem (can't be finished/data restored) because some Google apps are not updated

Reboot system
.

Enjoy

When you purpose a Guide, think to post also all the rom link/credits/sources, so thank you @erfanoabdi

I don't understand the hate lack of love for this guide. I have already done this process and been running S-GSI for a bit. I find this guide to be more straightforward, with better layout, and best of all it's located in the OP5 specific forum, instead of getting buried in a generic Treble thread. It also provided some really helpful resources for fixing some bugs I've been living with. Thanks to the OP for this, and I look forward to future developments of AOSP/GSI/Treble! (Maybe soon my phone won't need to think it's a Pixel XL!)

PS - to anyone reading, I'm looking for some help with the hw keys. End goal is to have BACK as the right hw key, and APP_SWITCH as the left. Remapping BACK and APP_SWITCH keys in /system/usr/keylayout/Generic.kl results in both my hw keys acting as APP_SWICH even though I have them seemingly set to BACK.

I can post my file as well as the original if it's helpful.

I don't know where you have seen some "hating" in our words lol

Just explain that there from a long time tutorial, just explain that is not a AOSP rom but a S-GSI ported from Pixel II and advise the OP to always link/credits original thead....

Fair enough. edited my post to reflect. But as far as I can tell, this seems like an original piece of work. Nothing to me flags as "stolen from someone else" or anything like that.

This thread explains how to solve some problems like changing the buttons. It is in Spanish but nothing that Google can not solve.

Can I do this using Pixel Experience ROM 9.0 instead of Mokee ROM?

Fairly sure answer is no. The rom you mentioned is just that, a rom, not treble based system image like described in this thread. Hope that helps!

No sorry you can't as PE doesn't support Treble. Don't worry it doesn't change anything to the UI or anything dw ?

Thank you for a quick reply. Don't quite understand Treble yet, just want to try Android Pie Will go for a OOS based 9.0 when released.
