Nevermind, got the answer from here.

If you can get the unit in the proper state by shorting, you can flash an android img or custom one using this tool; https://github.com/natinusala/linux-amlogic-toolkit Other repos that you may find useful: https://github.com/mluis/aml-flash-tool https://github.com/Stane1983/aml-linux-usb-burn

Hi While I thiknk your approach should have worked, a quick search revealed that something similar is done for a different family. Perhaps try this way:https://github.com/armbian/build/blob/9aa6e1e29ec2d397bbe223bebaa93bd13ef79818/patch/kernel/archive/filogic-6.16/patches.armbian/0007-build.sh-add-additional-build-script-config-defconfi.patch#L1909

Description: Hello everyone, I am encountering an issue where kernel configuration changes do not take effect when building an image for the Rock 5B using the Armbian Build system. Environment: Board: Rock 5B Kernel: Vendor Release: Noble Build Mode: Mini Build Tag/Branch: v25.11 Specific Issue: To ensure compatibility with Redroid containers, I need to change the kernel's CONFIG_ARM64_VA_BITS from the default 48-bit to 39-bit. What I have tried: I have attempted the following three methods, but none have worked: Ran the kernel configuration tool to change CONFIG_ARM64_VA_BITS, then copied the generated .config to userpatches/linux-rk35xx-vendor.config. Took the default config/kernel/linux-rk35xx-vendor.config, manually modified/added CONFIG_ARM64_VA_BITS=39 and CONFIG_ARM64_VA_BITS_39=y, and copied it to userpatches/linux-rk35xx-vendor.config. Created a kernel source patch in userpatches targeting arch/arm64/configs/rockchip_linux_defconfig and arch/arm64/configs/defconfig to force CONFIG_ARM64_VA_BITS=39 and CONFIG_ARM64_VA_BITS_39=y. Result: Regardless of the method used, the final Armbian-generated kernel remains at VA_BITS=48. It seems my configuration changes are being overwritten or ignored during the build process. Request: Is there specific logic in the Vendor/RK3588 build configuration that forcibly locks VA_BITS? What is the correct way to modify this parameter for this specific board/kernel combination? Thanks for your help!

Hi, I've read on here that you can apparently switch to a stable edge branch through Armbian Config, but the closest I can find is 'switch to rolling packages repository' and 'distribution upgrade to rolling unstable'. Are either of these correct? I'm running the Ubuntu Noble 6.12 kernel, btw. Many thanks.
