GSI ROMS not bootable With Verify Boot - Google Pixel 2 Questions & Answers

I want to use Official Havoc os 2.0 GSI on my pixel 2. However, I properly follow all the instructions for a GSI on any Android phone and it tells me this slot is not bootable. I have dug deep into my problem and found out it has to do with Verifying Boot but I do not know what it means. Phhusson claims that the pixel 2 does indeed have project treble support and I can also prove that it does with the treble check app on the Google play store. Phhusson also says you have to re-flash a vbmeta.img on to your phone after installing the GSI. I do not know what a vbmeta.img file is or how to extract it from the system image.
Any help would be appreciated at this point.

[HOW-TO] Flash A/B Treble GSI ROMs without TWRP

Android devices can have different designs, so there is no generic command or set of instructions for flashing a GSI to apply to all devices. Specially for Xperias am i writing this Guides for You. So please read carefully...
1. Ensure that You have the following before You start:
Latest Fastboot Version (Or the used fastboot commands may not work)
A Method for disabling Android Verified Boot (Part of the Guide)
An unlocked Bootloader State (Official Instructions HERE)
To Start:
Download the Basic Package from Google: https://developer.android.com/topic/generic-system-image/releases
Download the AOSP Vendor Package from Sony: https://developer.sony.com/develop/open-devices/downloads/software-binaries
Open up the Zip Files and place the 3 included Images on Your fastboot destination
Boot Your Device into Fastboot:
Code:
Turn off Your Device and hold VolumeUP while connecting via USB to a PC or use ADB to reboot to fastboot
Disable the verified booting (AVB) by flashing vbmeta.img:
Code:
fastboot --disable-verification flash vbmeta vbmeta.img
Flash the Vendor to the Primary A Slot OEM:
Code:
fastboot flash oem_a nameofthesonyoemimage.img
Repeat to flash to the B Slot OEM
Code:
fastboot flash oem_b nameofthesonyoemimage.img
Flash the GSI to the Primary A Slot System:
Code:
fastboot flash system_a system.img
Repeat to flash to the B Slot System
Code:
fastboot flash system_b system.img
Wipe the user data and clear the data from other necessary partitions (for example, user data and system partitions):
Code:
fastboot -w
Reboot:
Code:
fastboot reboot
Additional:
You can use any Android 9+ GSI out of the XDA Forum here: https://forum.xda-developers.com/project-treble/trebleenabled-device-development
To get Magisk/Root; just patch Your actual Kernel with the Magisk Manager App and flash the Boot Image together with the GSI (Example below)
Patched Boot Image for Xperia 5 Users: https://forum.xda-developers.com/xp...isk-v20-3-patched-boot-image-android-t4033547
I'll add that the Basic Package directly from Google in OP's post does not have functional call audio.
I highly recommend anyone try out Lineage 17: https://forum.xda-developers.com/pr...lopment/gsi-lineageos-17-0-gsi-archs-t4004673. Call audio works. FP sensor works. Camera also seems to work but I didn't really test it. I recommend flashing OP's patched boot image, too. Then all you have to do is install the Magisk Manager apk.
None of ExpressLuke's builds boot. Evolution hangs at the Evolution boot screen.
What we're missing now is TWRP. Lineage doesn't have gapps pre-installed, so we need a method for flashing them. I couldn't get MicroG services to work--apps could not see the accounts.

Call Bug confirmed but i had personally no Issue with the ExpressLukes Build. Just make Sure You don't use A64 Builds but ARM64 Builds (AB). Only GSIs with GApps was Havoc and Pixel Experience i think...
I'm running PE without issues Here (vbmeta from Google)
Can you elaborate on the vbmeta from Google comment?
And yes, only took one attempted flash with an A64 build to realize I needed ARM64 AB

Code:
fastboot --disable-verification flash vbmeta vbmeta.img
That needs to be done with the vbmeta image from the Google Basic package together with the flash of the System/Kernel and fastboot -w to be able to boot Up some ROMs. That needs to be done after each Stock Firmware flash...
In other words. It's a vbmeta image with disabled verify boot Checks that works on modern Treble Device Like the Xperia 1 & 5
Don't know btw what A64 is ... lol

Still hanging at the boot up screen for both Evolution and Havoc. Following your directions exactly. I must be doing something wrong.

Have You tried Pixel Expierence? If that doesn't works must be something wrong :fingers-crossed:
PixelExperience does boot successfully. Wonder why Havoc and Evolution didn't...
Is anyone able to get IMS working? I can't get VoLTE to enable (on any non-stock ROM) and checking the short codes menu confirms IMS is unavailable. Re-flashed stock and it provisioning correctly.
Thanks a ton for this guide. I have the Xperia 1 and am about to go unlocked. Too much google in my life. I am assuming all this stuff is basically the same. I've been around more than my share of unlocking / rooting experiences, so I am not sweating it too much.
Updated the Thread. No need for the vbmeta Image with Havoc 3.5 (Official GSI with GApps)! Means a more secure Device somehow...
I did an Overlay for GSIs, based on our latest Android 10 Framework https://github.com/phhusson/vendor_hardware_overlay/pull/214
Possible that You can grab it here: https://forum.xda-developers.com/showpost.php?p=82550641&postcount=889
Rename to FrameworkResCommon.apk and push it to /vendor/overlay (Replace). Should work in Theory... Maybe. It's a first try and i don't know how it will be implented
Updated the Thread with some Changes
Thread updated again with My latest findings. The OEM Vendor from SONY has to be flashed to A/B to. Added that Steps! Enjoy
Talented developer here, nice work. Been a while since Sony devices have had this level of support. My messing around days are behind me but it's nice to see as an old XDA fan.

Feeling honored to hear this! I was always a Friend of Xperia Devices and was User of NUTs Dual Recoveries, FXP and Doomkernels and started making/publishing own ROMs with the Xperia T back in the Days. It's really sad, seeing all the Telegram Chat Groups around with no Structure and all the missing Development over here on XDA. A lot of stuff around Android has changed the last Years, but it's still fun to try and mess around with all the new stuff. I just wish i had a Team to grow up the Support...
Hope i can bring some Life onto the new Xperias in a new age of Android. Your Words really pushed Me up again :angel: Thank You! :highfive:
System_A && System_B?
Are system and vendor taking up double the amount of space on the drive by being installed for two paths?

No. You have ROM storage and userspace storage on Your Device. Treble Android Devices have the Double amount of ROM Storage compared to non treble Devices. So it doesn't Matters If You only flash one Slot, Your user storage won't show more Space to use...
I understand the partitions are sized for two paths, which is the difference between an A only or A/B device (one system flag or two). Strange that the total space used wound't be displayed regardless of what the partitions are using. I was trying to gather the correct way to install a GSI rom and your instructions provided a new method for doing so. I guess I have to question whether the device I am installing on now is an A only or A/B device. Judging by the install size of 12gb for system which on other devices is roughly half, I am guessing it is an A/B device due to the space used.
Hi everyone, I just bought an Xperia 5, and being a little privacy concerned , I want to get rid of the Google parts of Android. After reading all the threads I found about this phone, and seeing that the Xperia 5 doesn’t have official support for LOS, I understand the most stable way to have a Google-free phones is by installing the GSI and then a Treble rom. I have the following doubts:
- Once I get everything installed following @Miustone 's guide, will I have to update the binaries every month? (I saw Sony posts vendor binaries every month on the Open Devices Website)
- If I install PHH’s treble Rom, will all the hardware work correctly (one message in this thread mentioned call volume problem)? What about the camera button?

Any Pixel Experience ROM or GSI for the A8 ?

Hello everyone, I tried most of the ROMS from here like feusionX, Qdroid, TreeUI and some of the old ones.
I liked the most of them, but what I am looking for is a ROM that has the Pixel experience feeling with all the features.
is it possible ?
I tried to use this method to use project treble on the phone but I wasn't lucky to flash any GSI.
every GSI I try It ends up in a boot loop.
what am doing wrong here?
any suggestion ?
Hello!!!
Look... Custom Rom for our phone is hard to find one that works (I say there's none)...
There's a Pixel Experience GSI that I was using it... https://github.com/ponces/treble_build_pe/releases
In this post you have the normal Pixel Experience and Pixel Experience Plus.
Difference??? Plus has some more modifications
I recommend using Vendor Quack...
[SAR][Vendor][10][A530F/A530W/A730F] Vendor Quack V2.5 For Galaxy A8/A8+ 2018

forum.xda-developers.com
There is no secret to installation, I believe you already have TWRP or OrangeFox installed...
First of all don't forget to backup your important files
1. Download Vendor Quack and Gsi in Arm64-AB-Vndklite format
2. Extract just the GSI so we can get the image of it (Winrar or 7zip are great apps that do the extraction work)
3. Restart in Recovery
4. Follow the same steps in the post https://forum.xda-developers.com/t/...-guide-for-galaxy-a8-2018-18-04-2019.3894881/
and then continue with my steps
5. Clean up Dalvik, System, Vendor, Data, Internal Storage and Cache partitions
6. Pass the GSI and the vendor to the device's internal memory
7. Install Vendor Quack
8. Now Install GSI
9. Install Magisk if you use
10. Reboot and enjoy your PE
Notes
Pixel Experience does not need install GApps
Bugs...
1. The GSI can crash hard sometimes and you have to force reboot on it.
2. If the above bug happens, the rom may come back buggy from reboot and you have to reinstall it again. (It's a little rare this is worth mentioning)

How To Guide Install any custom ROM on ROG Phone 5 / 5s (GSI)

Install any GSI on your ROG Phone 5​​First of all I want to say that I am NOT responsible of anything you do to your device.​
What is a GSI?
A generic system image (GSI) is a system image with adjusted configurations for Android devices. It's considered a pure Android implementation with unmodified Android Open Source Project (AOSP) code that any Android device running Android 8.1 or higher can run successfully.
GSIs are used for running VTS and CTS-on-GSI tests. The system image of an Android device is replaced with a GSI then tested with the Vendor Test Suite (VTS) and the Compatibility Test Suite (CTS) to ensure that the device implements vendor interfaces correctly with the latest version of Android.
What GSI do I install?
There are multiple GSI you can choose (AOSP, LineageOS, Pixel Experience, ProtonAOSP, etc).
Here is a list of every GSI you can install: Generic System Image (GSI) list
For ROG Phone 5, you need to choose a A/B partition style and arm64 architecture GSI.
How do I install a GSI?
First of all, make a backup of your device (optional):
In the Settings app: "Settings > System > Backup > Backup now" or "Settings > System > Local backup"
In TWRP (TWRP for ROG Phone 5/5s): "Backup > select Data and Super > Swipe to backup"
And unlock the phone using the app in the official site: AsusUnlock_1.0.0.7_210127_fulldpi.apk
Factory reset your phone in recovery or Android
Now, reboot your phone into fastboot mode (shutdown then press Volume up + Power)
Connect the phone to the PC with the side port of the phone
Make sure you have ADB and Fastboot installed, if not install this: Minimal ADB and Fastboot or this: Android SDK Platform Tools latest
Download the vbmeta and extract it: vbmeta.img
Now flash everything:
In a command prompt, type the following commands:
fastboot reboot fastboot
fastboot --disable-verity --disable-verification flash vbmeta vbmeta.img
fastboot erase system
fastboot -w flash system yourgsi.img
Replace yourgsi.img with the GSI you want to install
Now reboot your phone:
fastboot reboot
And that's it! You successfully installed a GSI on your ROG Phone 5!​
Common problems:​
Not enough space to resize system partition?​
If when you try to flash the GSI you get this error:
Resizing 'system' FAILED (remote: 'Not enough space to resize partition')
Then that means that your GSI is too big.
But don't worry, there is a solution!
Just type this before flashing the GSI:
fastboot delete-logical-partition product
This will delete the product partition and let enough space for the GSI.

Yes, on every GSI, the integrated phone speaker (for calls) doesn’t work. I didn’t noticed any other issues for the moment (not anymore with A12)
For the moment, only the fingerprint scanner, ROG specific features and secondary cameras are not working

No. This is a clean Android with Google pixel interface so Asus or ROG services are not installed by default like for example RGB on the back doesn’t work (I don’t know if it is possible to install them)

I'll think twice before flashing then, since RGB and dirac service doesn't work
Armoury crate can replace with kernel manager, but idk about RGB control apps

Hi, you can use Magisk it works. Flash the apk in twrp it is the easiest (flash the apk after flashing system and before rebooting to system because encryption doesn't work) or use boot.img method.

Main Q&A:
Q: What is a Generic System Image, GSI?
A: A GSI is a prebuilt system image that can be booted on devices that support Project Treble. In short, this System Image is a custom ROM but it uses your Vendor, Kernel from your previous/stock ROM.
Q: Okay, but why I would like to flash it on my Redmi Note 11?
A: As we have already known, MIUI does not perform exactly well in the recent years, especially on such a low end and underpowered phone. GSI helps us getting a taste of AOSP's cleanliness and smoothness before the developers finish making actual custom ROMs. This is a temporary solution, good enough to use, please don't think or complain if your GSI perform badly, since it is not a ROM or trying to be one either.
Q: Why do we need a dedicated tool and such time wasting thing to do? Can't you just flash it in a custom recovery?
A; From Android 10, devices with it come equipped with a new partition scheme, as known as Dynamic Partition. It helps speeding up OTA updates and make the partitions more flexible in size. But also creates a huge difficulty in flashing those GSI, that is why you cannot flash the image in a custom recovery.
Q: My terminal window freezes at a certain progress for too long! What should I do?
A: This case often happens with Windows users. Everything is quite complicated BTS, but the workaround is just spamming Enter key several times every minute or two.
Q: What if I want to install a GSI on top of another one? I already flashed one, do I need to restore my MIUI or AOSP rom to flash GSI?
A: It is not necessary, you can flash a new GSI on top. The tool will clear your previous GSI without erasing required stuff from ROM.
Q: My GSI does not boot, what should I do??
A: I highly suggest using GSIs based on Phh's work. Those are often called Phh GSIs. Secondly I would highly suggest against using "Ported GSIs", those are often based on Erfan or Xiaoxindada's GSI tool, they are a port from a different device's ROM instead of directly built from source like Phh. Here is a list of GSIs based on the man himself, Phh.
Q: Bro my phone just boot to TWRP and nothing happens, computer still waits for my device??
A: Like I said before, you can try spamming Enter key. It is also likely that your TWRP does not support Fastbootd (Fastboot Dynamic) environment, an easy workaround for this is using MIUI's boot (kernel) image, stock Fastbootd mode will be used.
Q: Which Android version can I flash??
A: You can flash corresponding or NEWER Android version GSI with the ROM you are coming from/installing GSI on top, you cannot flash a lower version one. For example, you can flash Android 11, 12, 12.1, 13, bla bla GSIs when coming from stock Android 11 MIUI ROM (Android 11 Vendor for people who understands)
Q: Can I use this tool on another device?
A: Yes, with proper bringup and changes in the tool for it to compatible with your device and it will work. But I will not be responsible for bricks, which I always won't xD
More questions and answers will be updated later.
Reserved.
Thanks for this Awesome Tool. Quiet Simple and efficient.

[Guide] Installing Updated GSI

So, I was testing various and came across the guide for installing LineageOS17 GSI in the guides section. The way mentioned seems to be working
Procedure-
Install TWRP with latest security patches according to this guide https://forum.xda-developers.com/t/updated-september-2022-how-to-root-a7-2018.4488289/
Now, download Latest LineageOS19.1 vndklite-secure GSI.
Make sure to have backup of your internal storage, it might need to be wiped.
Install this GSI and right after that install Quantum Kernel 2.5 GSI version(for mtp) (check in attachments, it has Magisk 25.2 instead of 20.4 as mentioned in verbose) and then Magisk. After boot, check if MTP works in system, if it reboots, force reboot to TWRP and format Data and then reboot. That should fix it.
Without the kernel, seems to be stuck at logo.
No critcial bugs I have seen till now.
PS: always maintain a backup, I am not responsble if something goes wrong, like data loss.
Now, haven't tested it, but seems to me that any version other than vndklite-secure will have the 'camera in use' problem. So, try and let me know if that's the case.
Note - TWRP used is from a telegram group, which I couldn't share without the permission of owner. Search for it and you'll find it in A7 2018 telegram support group. TWRP version is 3.6.2.
Dmverity-disabler is to be flashed according to how to root guide only.
Tested on SM-A750F/DS (INS).
The reason why GSIs later than android 11 have a lockscreen bug is due to a vendor issue, in which Android 10
vendor of A7 2018 is not compatible with these GSI's. Apart from some Android 10 GSIs (like Havoc), lockscreen and everything works on these.
Abridged from https://forum.xda-developers.com/t/sm-a750fn-ds-unofficial-lineageos-17-1-gsi.4195065/
The img file for TWRP 3.6.2 is https://sourceforge.net/projects/batuhan-s-builds/files/TWRP/a7y18lte/recovery.img/download
To flash it as tar, use 7zip or any alternative to arcive as tar with default options, just make sure the image file remains as recovery.img, because it is present in this form on the phone partition. Tar can have any file name.
Source Telegram group for TWRP img file is @Exynos7885Updates
No sources have been specified by the developer.
For Indian SM-A750F, BL FILE IS INCLUDED
Note: For Camera in use error, always try to use vndklite versions of GSI, they have specific patch to work with some specific types of vendors. Currently looking for lockscreen fix, most probably, it is also a vendor related problem.
All of these are android 12 or 13 ones.
Possibility of usage:
Works Complete with magisk (including working Lockscreen): FLOS19.1(https://github.com/ChonDoit/treble_flos_patches/releases) [use (VNDK)lite secure ones, stability check needed]
no lockscreen : AncientOS S,ProtonAOSP 12.4.1, ProjectBlaze12.1, LineageOS19.1, LineageOS 20.0 TD-based VNDKLite(no bluetooth), pHH A12.1 GSI (secure), OctaviOS(vndklite), Evolution X 13 vndklite (no bluetooth), Miku UI 13 (no bluetooth), Pixel Experience Plus 13 (VNDK)lite, (no bluetooth),
with 'camera in use': ArrowOS 12.1, CherishOS, DotOS, Pixel Extended 13, Pixel OS 13

where can you get twrp 3.6.2 for a750?
I have the latest stock firmware. Do I have to downgrade?
Did your phone has the latest firmware when you installed GSI ROM? Did you downgrade the firmware?
Also are banking apps like GPay work on GSI ROMS?

No you don’t have to downgrade, just use the older 2020 Update BL file.
You can use UPI if you can securize the gsi and follow the steps of fixing safetynet. Search them
Thank you for the response.
Can you update the BL file file from 2020?

No, updating with later BL's can cause issue with custom recoveries.
Does anyone have issues with mobile hotspot in GSIs. In OneUI roms, mobile hotspot works normally, but on GSIs, it does turn on and discoverable, but without internet access. USB tethering works fine on all roms though.
My phone is SM-A750GN
