If you flash any firmware that makes device seem to be dead do the recovery:

1. entery maskrom by

• plugin in usb a - usb a cable to h96 max v58 and laptop
• shorten second resistor with capcitor
• plugin power cable to the box (if all is fine you will hear ping from use device connected)
• check in RKDevTool v.2.96 if device in Maskrom Mode has been found

2. Firmware update

Click firmware and chose stock firmware at the moment latest is"H96 Max V58 RK3588 20230728.1802.img" Click update and log should look like on the right side of the box.

If switching to MaskROM fails remember to disconnect both USB and AC adapter from the box and try again. After few attempts it will work.

Hope it will help other people progress with making this device usable under linux. The image of batocera-rk3588-rock-5b-39-20231108.img is making device dead. IDK if change of DTB in the image will make it work. When you are in stock image uploading different image is easy you can you toothpick on reset button and plugin ac adapter. Device will enter loader mode so you can use Factory Tool from Rockchip - https://www.youtube.com/watch?v=RUNV_9gslqc&pp=ygUbaDk2IG1heCB2NTggZmlybXdhcmUgdWRwYXRl

You can also recover from linux using rockchip upgrade tool with: sudo ./upgrade_tool uf /media/user1/Samsung\ USB/H96\ Max\ V58\ RK3588\ 20230728.1802.img -noreset

where you just put device in maskrom mode and fire above command with correct path to firmware image.
