Dear folks,

Here is my message. I recently tried to upgrade my Prospero X1 (Bitcoin-miner) with
Rockchip SD Firmware Tool and SDBoot.

I used these links provided by BlackArrow:

http://prospero.blackarrowsoftware.com/files/SD_Firmware_Tool_1.4_with_sdboot_1.17_2.07.7z

My technical problem arises when I used SDBoot v2.16 cause it gave only
blackscreen, I tried all SDBoot versions, but I found out that only
SDBoot v1.17 works, but after flashing the boot-up screen with the BA logo
just keep eternally hanging.

My question is how can I restore this issue please? Is there a solution
for this?

Waiting for your kind response. Thanks for your time.
