Possibly Baofeng have re-engineered the DM1801A like they have for the DM1801

Normal process to enter firmware update mode on these radios (GD77, DM1801 V2 etc) , is to hold the 2 buttons on the side (not PTT), and turn on the radio

However, Baofeng have completely re-designed the new DM-1801 and it is not compatible and perhaps does not have a firmware update mode.

If Baofeng have now changed the internal hardware on the DM1801A, then there is no possibility it can be supported.

Contact the vendor and complain that they did not correctly advertise the radio as the new version

See the thread about the DM1801

Then buy a RT-3S / MD-UV380
