Update:
Nevermind, Those are just moved into bootable/deprecated-ota/
But still... it's considered as "deprecated", means it'll be gone in anytime soon

We booted 15 but that's still a concern tho, If non-A/B would finally be unsupported... We'd need very ugly workarounds, even if we runs mainline kernel

Booted.

Truly no device-specific adaption is needed this time, haha

Screenshot from A15 GSI

(looks different, right? especially, on "Build number" field...)
(unknown baseband version doesn't mean it has broken baseband, tho)

The 1GB RAM device is still not dead yet XD, Thanks to zer0def for testing

How to enable revamped settings homepage and new statusbar icons on 20240907 AOSP 15 build:

1. Root the device (Magisk or APatch)

2. Enter the device's shell (Terminal Emulator app or ADB shell)

3. Type su, Enter, Grant root permission

4. Copy and paste the following commands:

aflags enable com.android.settings.flags.homepage_revamp
aflags enable com.android.settingslib.flags.new_status_bar_icons

5. Reboot

(I tried to set it to enabled by default at build time, but it didn't work...)

Yeah, sadly, it's pretty sure that kernel 4.19 won't live for long... (at least still fine on 15 QPR1 beta tho)

It's strongly recommended to stay on Android 14 or lower if you want to keep using the device normally.

(I'll let official LineageOS stay on 21 forever, will push device tree branches for 22 too for who want to build)

about kernel 5.4... I have skill issue and no enough free time to continue working on it, probably doesn't worth really much as well

when mainline gets decent, sure I'd try to run Android on it, and get very basic features working, basically no more plan than that for Android.
