The flashable image for this release is the one already shared from Drive.
Kernel 7.2.10 for cards already flashed
uname -r is 7.2.10-edge. The package replaces masi-kernel-edge-sm8550 7.2.2-edge-sm8550-3.
Each image has its own ext4 UUID. The installer reads the UUID of the root filesystem that is running and repacks /boot/KERNEL with that UUID. It does not keep the UUID baked into the published kernel. If that UUID cannot be read, the install stops.
Download masi-kernel-edge-sm8550_7.2.10-edge-sm8550-1_arm64.deb from this release, then:
sudo apt install ./masi-kernel-edge-sm8550_7.2.10-edge-sm8550-1_arm64.deb
sudo reboot
uname -r # 7.2.10-edgeABL after reboot: Vol Down → Set the Device → your model → Linux → START.
