Hi all!
Maybe this will be useful to someone.
I had a TVbox H96Max H2 with firmware RK3328-BOX_7.1.2_20180620.2051_H96MAX
I tried flashing other android firmware of different versions but without success.
I tried to install many versions of Armbian in different ways but it did not start from the SD card and SD+USB.
The Multitool also not start. I tried launching with different .dtb
This is the only method that worked for me: I re-recorded the U-boot using Windows 10 and RKDevTool GUI
I download U-boot from here:
https://github.com/hexdump0815/u-boot-misc/blob/master/misc.rk3328-no-sd-boot/rockchip-u-boot/u-boot-image-for-emmc-h96max-rk3328.img.gz
Then I recorded to the SD card using the Multitool from straight from this thread
https://forum.armbian.com/topic/26978-csc-armbian-for-rk3318rk3328-tv-box-boards/
I used Linux Mint and Etcher GUI to record Multitool on my SD card.
I added this image Armbian_23.8.1_Rk3318-box_bookworm_current_6.1.50 to the img folder of the SD card
I only need a server.
The Multitool loaded from the SD perfectly but the Armbian installation is 98% frozen. After some time I rebooted the TVbox... and complete success. Armbian server works well.
I extracted .dts from the android firmware. I recorded several UART logs.
Once upon a time I soldered wires and connected a UART converter and recorded logs, but not always, unfortunately.
I want to say thank you to all the developers and enthusiasts of this project!
