I really don't have any use for my tv box, and i'm trying to find something to do with it, but i think there is also something wrong, because in android it keeps closing apps and sometimes even rebooting (temps are fine, i replaced the heatsink with a larger one), and while in linux firefox would sometimes crash tabs or close itself

Flashing the ArkOS (from the device RG503) and replacing the .dtb and the "uInitrd" (from the linux image) i can get it to load the splash screen, but nothing else happens, i tried to flash the openwrt firmware but i can't mount the boot partition to replace the files, that's what i can't figure out how to do it, the linux see most of the partition as "unknow" format

i compiled a custom u-boot on the device with the armbian station image. dd it over to the partition2 and now my box is broken since days. Its no longer detected, so i cant flash anything at the moment.

If i press reset button and plug in the otg-cable the device is not detected by android tool nor by the rockchip factory tool.

I also don't want to touch the other 5 devices. So if have only one device to experiment with.
At the moment the u-boot (i guess its the one from the ROM) looks for an spl-partition on the sd card and emmc.

Yesterday i found out how to partition the sdcard. Primary partition fat32 with uboot.bin on it.
but i am still not any further. It now complains about a misc partition.

I need help and have to do further reading to get the box back to work i guess.
I already ask DigitalDaz for help, but he seems to be rather busy.

Are you definitely using the correct USB port? The only time I had problems with the USB being detected, I rebooted the PC and it started detecting again.

The factory reset tool should definitely see it.

@Florian If you have serial console access and get the u-boot interface you should be able to boot from that. I will PM you a number you can call.

I got a uboot prompt again!
I found this advice in another board, so i tried their layout for the sd card.


it is worth clarifying that in addition to 1 partition named uboot, the bootloader is looking for an EFI partition

Code:
Device          Start      End Sectors  Size Type
/dev/mmcblk0p1  16384    49151  32768  16M Microsoft basic data
/dev/mmcblk0p2  49152  573439  524288  256M EFI System
/dev/mmcblk0p3 573440 10557406 9983967  4.8G Linux filesystem


Code:
Device          Start      End Sectors Type-UUID                            UUID                                 Name  Attrs
/dev/mmcblk0p1  16384    49151   32768 EBD0A0A2-B9E5-4433-87C0-68B6B72699C7 925E253E-2941-EA43-A7B9-050C9065846B uboot
/dev/mmcblk0p2  49152   573439  524288 C12A7328-F81F-11D2-BA4B-00A0C93EC93B C375ECD8-92DC-0D42-ABCA-8046B74A3DC2      
/dev/mmcblk0p3 573440 10557406 9983967 0FC63DAF-8483-4772-8E79-3D69D8477DE4 C9EAC18A-C5FD-9E45-BB11-9CBB6A12F588

creating partitions:

Code:
echo -e "\ng\nn\n1\n16384\n+16M\nt\n11\nn\n2\n\n+256M\nt\n2\n1\nn\n\n\n\nw" | fdisk /dev/mmcblk0
echo -e "\nx\nn\n1\nuboot\nr\nw" | fdisk /dev/mmcblk0

After this i copied my backuped original u-boot (partition2) to the newly created first partition.

YES!

It also works with the uboot.img extracted from the T95Plus firmware.

i am using MicroK8s on the standard image. Works ok. I am actually unable to get a shared storage solution working at the moment.
