Full dump ZG834-V1.2 for vidtoo controller Avalon 841 - for programming the soldered flash memory chip via a programmer (such as ChipProg48 and similar).
In the archive, dumps were read from working microcircuits.

If you do not have a programmer and an adapter plate for such a flash memory, then do not buy this dump. This is not a firmware!
In case of failure, no claims will be accepted, go for it at your own peril and risk
