Android 14 Rockchip - Magisk app says not installed after flashing the patched boot.img

[mo123]

Device: Rockchip RK3588
Android version: 14
Magisk version name: 28
Magisk version code: 28001

On Rockchip Android 14 arm64 if patching the boot.img with Magisk v28 the patched image is the same size as the stock image even though the Magisk app said patched successfully.

If I use the previous Magisk version then the patched boot.img is about 100KB bigger in size but Magisk also doesn't say Magisk is installed even after flashing the patched boot.img.

After flashing the patched Magisk boot.img then the Magisk app in Android 14 says Ramdisk - Yes, Magisk Installed - N/A so Magisk is not installed and can't give root?

On Android 12 on the same device, Magisk root worked successfully.

Magisk v26.4 and Kitsune Magisk v26.4 works on Android 14, some later commit must have broken something.

Please check if Magisk supports boot images from this Android 14 boot image or how to solve it.

I haven't look carefully into this due to time reason, but I think it would be better if we have more logs. Please follow https://developer.android.com/studio/debug/bug-report to grab a bugreport and attach it here

Here is the Magisk install log

I see this error in the log for Magisk v28 but not with Magisk v26.4 where it is working
'unknown/unsupported ASN.1 DER tag: 0x00'
