Thanks for the ultra fast reply

I will try to flash it with fastboot, any prerequisites necessary or just flash your gsi ROM to the system partition except unlocked bootloader? wipe? erase system? factory reset? root? flash Stock ROM?

there is no vbmeta partiton on my phone, even when I try to flash vbmeta via fastboot it fails

[Treble-Enabled Device Development A/AB ROMS] devrieshh:
why dont you try flashing stock vendor.img and then stock boot.img after flashing system-quack-arm64-aonly-go.img

[Treble-Enabled Device Development A/AB ROMS] jdills1196:
This is odd. I can flash my device to the Google Developer AOSP images fine (here). However, I've tried multiple versions of your ARM64 release and it'll just go straight to fastboot on restart and will never boot into the OS. Then I'll flash it back to the GSIs on Android's website and it works fine.

Any suggestions that won't require me to build an image from source? If not, it's okay. I'm just trying to get root so I can get a copy some of the firmware on the device (since it's a new, cheap, android tablet that for some reason the device mfg doesn't have firmware anywhere, uses a custom tool for software updates instead of OTA, etc). I'll probably return it once I get done with all of this anyway.
[Treble-Enabled Device Development A/AB ROMS] TomRon:
flashed system-quack-arm64-aonly-go.img (AOSP 10.0 v217) via fastboot and again boot loop

changed nothing and ends also in a boot loop

after that I wiped the phone with "fastboot -w"

[Treble-Enabled Device Development A/AB ROMS] icebergREAL:
Hello LeonardoGC,

My bad, I didn't create an issue on the subject so you're free to go :)

I posted about this in my device's specific section, in the treble guide thread, here is the link to the post.

Same link as above, I still have tests to do (like always) for newer GSI's but there are just too many to test them all. I think that I'll stick to a bunch of them and try to give feedback regularly to inform community and to help devs. Maybe I'll open a new thread just for these updates but not sure it'll be THAT useful, so I'm hesitating.

Head over here and read the documentation on the subject. You can(should!) apply filters to show only errors or you can sort out apps to scan/not scan and many other useful options!

Logcat files are logs of what's happening on your device, and there are tons of lines that you don't want to read, trust me! You want to pinpoint your critical error(s), and check the few actions that happen right before the crash. So I highly suggest you go to the above link and take time to test/read about these features ;)

Personally I'ld recommend using CAOS / BLESS from [MENTION=8281637]eremitein[/MENTION], as they are the most stable Quack GSI's i tested until now. No deep sleep reboot bug, really important when you want to use it as a daily driver.

However, as it has been said many times, a device isn't another. So I cannot say about what will work on yours or not. Android need drivers, and Samsung is the mean guy in that story!

Feel free to navigate through the android developers site I linked, there are sh*tload of informations. Actually if you want to learn about Android architecture, this is the place to be.

Oh, and here too!

[MENTION=1915408]phhusson[/MENTION]

I have Motorola G7 plus XT-1965-2

just flashed the newest floss build of quack....... no problems and and easy execution on my device......so far everything seems to work....

I have ARM64 AB.....which is very aggravating... This is my flashing process for any Treble GSI for my architecture and it seems to work.... I back up my user data to external....then reboot to TWRP recovery.... I format data then factory reset wipe then advanced wipe dalvik, system, and data,......then I reboot which ever slot I was on back to recovery....switch slots then format data again, factory reset, and advanced wipe system, dalvik, and data.... Then set slots to a reboot to recovery from recovery....flash your system .img then reboot recovery...if u dont reboot after u flash the img it will bootloop...then flash any zips...reboot system ......profit

I have found that sometimes with these ROMs my bootloader goes stupid then switches slots trying to boot my stock boot image in one and other has my twrp image...so the slots are playing tug of war......you can also after u wipe back out to the menu screen of twrp and hit backup to see what size is in the data /system then switch slots and do it again to see if they match if they dont match probably a looper....
[Treble-Enabled Device Development A/AB ROMS] LeonardoGC:
icebergREAL,

Thanks for the information provided.

[Treble-Enabled Device Development A/AB ROMS] phhusson:
What you can do is flash my GSI, try to boot it, boot Google's userdebug GSI, and retrieve /sys/fs/pstore and/or /proc/last_kmsg

It should contain infos about the fail.

Just to be clear, you flashed A/B variant of my GSI right?

That's most likely your issue.

Don't use fastboot -w, it is known to be broken, especially on oreo vendors.

Do factory reset using the stock recovery.
[Treble-Enabled Device Development A/AB ROMS] TomRon:
Tried it again

Stock ROM reflashed

booted to OS and made the usual android configs (SIM, Wifi; Password, Google)

enabled USB Debugging

adb reboot bootloader

erased system -->fastboot erase system

flashed the system-quack-arm64-aonly-go.img (AOSP 10.0 v217) --> fastboot flash system system-quack-arm64-aonly-go.img

flash procedure was finished --> fastboot reboot

as always phone went into a bootloop

booted into Stock recovery

performed a Factory Reset

reboot

and again boot loop

is there any Information which I can provide to spot the issue?
[Treble-Enabled Device Development A/AB ROMS] phhusson:
I've just looked again your model number.

How do you know you're supposed to use aonly variant?

Because i'm pretty sure you're supposed to use A/B variant.
[Treble-Enabled Device Development A/AB ROMS] devrieshh:
you can try this if you have reinstalled your stock rom...

reboot in twrp recovery - wipe just wipe data -reboot fastboot

flashed the system-quack-arm64-aonly-go.img (AOSP 10.0 v217) --> fastboot flash system system-quack-arm64-aonly-go.img

-fastboot flash vendor vendor.img

-fastboot flash boot boot.img

-fastboot reboot
[Treble-Enabled Device Development A/AB ROMS] TomRon:
From my point of view if "seamles upgrades" are not supported then the device is A-only, my device doesn't support seamless upgrades...

which treble checker you suppose to use to check treble status?

OMG just checked it again with Treble Info... and it says A/B..... damn, to stupid to read

BTW where did you retrieve the info that its A/B and not A-only?

Thanks!

A-only is a "normal" system whereas A/B got system as root, you can get more infos about android partition layout here.

You can take vendor.img and boot.img from your stock room and flash them over your flashed new rom

-fastboot flash vendor vendor.img

-fastboot flash boot boot.img

-fastboot reboot

If this doesn't work you can restart in twrp and wype data than reboot,if that doesn't work you have to reinstall stockrom and just start alover...

Since the Stock Vendor isn't working well with Your GSIs like i told You some Time back, was i researching a lot about something i could do to help fixing stuff. Since SONY is providing a lot of Support for People like us do they provide pre-made and downloadable AOSP Vendors from here: https://developer.sony.com/develop/open-devices/downloads/software-binaries

I guess You aren't aware of this till now since it helps 0% to flash this to oem_a and oem_b combined with GSIs based on Your Work. I tested the same Vendor with with SONYs AOSP Compiling Guide and got everything working last Night with pure AOSP Sources. VoLTE, Wifi Calling, Always on Display, Camera Button and so on. Haven't tested Googles GSIs yet but that's the next thing for Me. Will report back if You want me to once i flashed it.
