@Efe Çetin I have tried this before, but I think there are more changes that has to be made for 5b. For example the pcie power is set to 1.8v instead of 3.3v https://github.com/torvalds/linux/blob/master/arch/arm64/boot/dts/rockchip/rk3588s-orangepi-5.dts#L82-L91 ... I'll try some changes if I have time this weekend and I'll let you know. Thanks.

Hi, is is possible to port the kahdas-edge2 changes (https://github.com/armbian/build/pull/6335) to the OrangePi 5b device tree?

I had some troubles with the latest build (Armbian_23.05.0-trunk_Orangepi5_lunar_legacy_5.10.110). First I had to restore the 5b specific device tree (rk3588s-orangepi-5b.dts) because with the modified rk3588s-orangepi-5.dts the Wi-Fi and the eMMC doesn't work. So far everything works fine with the exception of the bluetooth. After each boot I have to manually attach it: hciattach /dev/ttyS9 any ...otherwise the hci_uart module is not loaded and no hci device is available. Once attached the bluetooth works fine and I can pair my mouse with it, but not my bluetooth keyboard?!? Seems like the adapter doesn't even detect the keyboard. When I run bluetoothctl scan on - the device (with a strange address: 00:00:00:00:0E:3E) doesn't show up. I can easily connect the same keyboard to my macbook with no problems and it works just fine. Is there anything that I'm missing?

@SteeMan Thank you for the advice! That's my other problem. The only link to the stock firmware I can find is dead and in addition the board doesn't seem to switch to recovery mode by pushing the button (no USB device pops up). I was thinking of a trick where I can interrupt these pre-boot scripts through the serial console. I'm not very familiar with the u-boot internals, but apparently I have to start reading the code to find a backdoor. Thanks for the response though!

I found the TV box that played couple of years ago... and bricked 😞 The box looks like this one https://bestedshop.com/index.php?route=product/product&product_id=213 Seems like I flashed it with Khadas VIM bootloader and now it enters a boot loop because it's failing the vim_check preboot script. I tried all sorts of images via the SD card but it seems it ignores all of them.
