[Radio model not supported] New Baofeng 1801 won't enter in upload mode

CPS_DM1801_A6_V001.02_666
I connected it with the cable that was included by cutting off the usb plug and connected it to usb-ttl
black -gnd
blue -tx
brown -rx
everything works and reads

great news, I was already preparing a ttl to rs232 converter to do this, I was going to take advantage of an 8x1 cable that I have here, if possible share this feat with a photo.

I did it here and it only worked according to this scheme, the TXD pinout is inverted and it is connected to the RXD of the CP2102 converter, and the RXD is connected to the TXD of the converter.

Boa noite, no meu dmr 1801 coloquei o baofeng modelo BF 17 acho que é UV5R e o programa do CPS_DM1801_A6_V001.02_666 não precisa apertar nada ele entra na função sozinho e fica piscando a luz vermelha só alegria

Good night, in my dmr 1801 I put the baofeng model BF 17 I think it is UV5R and the CPS_DM1801_A6_V001.02_666 program does not need to press anything it enters the function alone and the red light is flashing just joy

Hi,
on the webpage

https://www.hamradioshop.pl/

they are offering the DM-1801. Obviously the new A6 Version with SN: 18DMxxxxxx. They are writing: the A6 Version is protected against updates with opengd. Therefore one should use an special CPS, which they have available for download by a link on their page. They are writing also, that a UV-5R cabel would be needed for programming t6he radio. This cable has a USB to RS-232 converter as described before. This info may can help.

Are you sure about the S/N, I would expect a 20DM1801xxxxxx

Cheers.

Hi, I downloaded the file, it's just cps and factory codeplug. Maybe there's a secret key combination I need to press...

Normally the official CPS application does not include the firmware loader. Baofeng and TYT and Radioddity etc always use separate applications for the firmware loader.
Because this is completely new radio, its possible there are no official firmware updates for this radio

Anyway, there is no purpose discussing the official firmware for this new type of DM-1801 because it can never be supported by the OpenDM1801 because the radio is actually a completely different model of radio with different CPU and different electronics etc etc

good morning, I tested using a cable for the UV-5R and it didn't work, it only worked with the cable I made, there is a difference in the TXD pinout between the UV-5R cable for this new model, the pins are inverted.
