VU+ Solo Help Trying to Identify Manufacturer of Solo clone

Hi all bought this Solo Clone off ebay as faulty didn’t know at the time it was a clone nothing on display, power on red light then went green no display. Tried USB flashing both boot and Black hole images the box goes through the motions correctly but when reboot no display. Don’t know if I’m using correct images. Have attached some pictures hopefully there’s a Guru out there that can enlighten me. I know it’s not a Ferrari as it has no sub board but it does have a ST MICRO STM8S105K4T6C chip on the board and a Jtag connector next to it No version numbers anywere on box.

Have done some more digging and found that the box is made by Vu+ Solo Shenzhen Air Digital Technology Co., Ltd
PCB is a model AIR900HD no support on the companies website waiting for them to reply to my email.

Hello mate,
i dont know very much about these boxes to be honest but a little while back whilst i was experimenting with images for my solo clone something similar happened to me. - flashed a couple of images, the box went through the correct procedure and rebooted but no display, just a black screen.
In the end i got it going by flashing a Ferrari V2(a) image which worked a treat. My box is not Ferrari by the way! I have been using Ferrari images ever since with no issues at all.
This is probably a bit of a wild long shot but it worked for me so it might be worth a try while your waiting for a reply to your email.
Like i said my knowledge is very limited but i thought i'd share my experience any way.
Hope you get it sorted soon.

Cheers
will give that a go, Air Digital are not interested in supporting as they no longer make that model.
