I told you yes and you will see that it is very easy
I am currently waiting for the shipment.
I want you to inform me what and how ( step by step ).
I need step-by-step instructions, i.e. how to connect the programmer to the motherboard, what software, how to do the programming, what to install, etc. I haven't dealt with this and I don't want to relive the failure that happened to me with RS232.
Can you prepare such an instruction ( step by step ), surely other users will also be useful.
Here we will provide you with the Software for your programmer and all other details related to the CH341a Universal Programmer.
1 Detect chip
2 Erase chip
3 Verify
4 Load firmware from files
5 Burn chip
When Ch341 is connected to the Box, the display lights up
CAJE Please,
Writing you to write step-by-step instructions I want you to show each step with screenshots of where to connect the clip, how to configure the programmer, how to install the programmer, how to handle the software to install the software. Do it with screenshots ( each stage of programming ). Such pictorial instructions show all the steps which dispel any doubts.

I have reprogrammed the chip using the Ch341A programmer. A very simple procedure to convert the software from Ma.s to GTMEDIA. It is important to connect the clip well to the chip on the motherboard of the device. The whole procedure takes a maximum of 5 minutes.
PS- via RS232 cable I think faster and without much stress ( less disassembly and application programming )

Uart don't work on my V8 UHD. Don't know what component is W61 , and its not clear how it works on original circuit. Removed original circuit and used a max3232 and now works ok.

Edited: Forget that it works, bud also original circuit works, see next post

Ok W61 is a N-mosfet WNM6001, maybe the original output is for uart at 5v level?

Ok today i tested it and original circuit works ok.Tested on COM1 and using a ftdi usb conversor. If someone have a not working pcb, can make photos of components and pcb version.
