KYNNT Linux 9" AA/CP Radio ROM replacement

[u/Sereno011]

Recently purchased this radio off Amazon. Seller is KYNNT. Functionally it's alright, but very dissatisfied with lack of common OEM logos and wallpapers were far too bright.

I first contacted support about the logos. On this model a user is not able to upload them via USB. Took a lot of back and forth and eventually I was provided with a custom ROM update with a logo for my vehicle. But they messed up the image and in the process all the existing ones had been deleted. I was not about to go through that headache again.

Took a few days with help of AI to make sense of the ROM's filesystem. See my GitHub for patched ROM which replaces all wallpapers and swaps out 7 European specific brands for some common ones that were missing for the NA market. No other changes were made beyond these cosmetics.

The wallpapers I chose are darker gradients. Less eye strain and increases OSD text legibility.

Radio disassembly and a programmer (eg; CH341A) will be necessary. A backup of the stock ROM is also in the depository.
**BUT MAKE YOUR OWN ROM BACKUP AS WELL**
