I try to flash GSI treble on HTC U11 Life but it doesn't work...
fastboot flash system_a /Users/thibautmaringer/Downloads/PixelExperienceP-arm64-ab.img
Sending sparse 'system_a' 1/3 (1048572 KB) OKAY [ 36.946s]

this is the way to go when, i won't say if, HTC goes down and support will end for our phones.
maybe a bit more difficult than to just flash an image as we've always done, but not much more.
if HTC doesn't present a 9.0 before Xmas i will definitely install AOSP instead with no google at all.

You should place the system.img (gsi) in the same folder where your adb and fastboot installation is. And you can see on the display of your device the progress of writing from 0% to 100% maybe you can have a look at it next time you flash something to see if it flashes at all.

./fastboot flash system_a system.img

It works that way, already did it three times with three different systems. What file are you using? Do you even have the android one version of the u11 life or the Sense version?

Android 9 GSIs are in an very early development stage and if you would read their threads you would know this. I dont even try it until phh treble has its first stable release.

Android 8.1 GSIs

Today i tested for the first time an Android 9 GSI, phh treble got an update yesterday with a lot of bug fixes and it looks pretty good so far. Sadly we have the same bugs as with Android 8.1 GSIs. Its the first time phh treble gsi android 9 has GApps + Root integrated. I think those bugs we have are related to a faulty treble integration by HTC and cant be fixed by a dev of a GSI but its running good so far.

Sadly we have the same bugs as with Android 8.1 GSIs and one additional bug. Its not possible to connect to hidden wifi networks, as long as the networks ssid is visible there is no problem to connect to it. Its the first time phh treble gsi android 9 has GApps + Root integrated. I think those bugs we have are related to a faulty treble integration by HTC and cant be fixed by a dev of a GSI but its running good so far.

Hi. Sorry but for me it doesn't work again. I did all the steps:
1) unlock bootloader
2) I'm on stock 2.13.401.1
3) I flashed using fastboot flash system_a system.img (from phh-treble 9 GSI with su and gapps)
4) it says again
Code:
fastboot flash system_a /Users/thibautmaringer/Downloads/system.img
Sending sparse 'system_a' 1/2 (1048572 KB) OKAY [ 32.109s]

and on my phone it says "flash success 2/2 start flashing" but nothing happened.
So can you explain how you did that well because for me it doesn't work.

Hmm, there are just two things where i could imagin that it causes a problem for you. First if you try to flash stuff from bootloader and not from download mode. Second would be a problematic usb connnection during the flash process. I have no other ideas sorry.

Do you have
Code:
secure boot: PRODUCTION
? Because my usb connection is good and I flash files in "htc download mode"
Maybe can you explain precisely how you flash the GSI ?

1. I remove my Google Account from the Stock System
2. Reboot to bootloader - reboot to recovery and factory reset the device
3. reboot to bootloader and identify the active partition
4. reboot to download mode
5. flash Stock boot.img (because i was rooted before)
6. flash GSI system.img
If you need it more in detail just read the first posts in these two threads: https://forum.xda-developers.com/u11-life/how-to/collection-htc-u11-life-android-one-t3768265 https://forum.xda-developers.com/u11-life/how-to/treble-gsi-running-android-one-8-1-t3823015
And yes i have secure boot production and device state unlocked
