Re: New BAOFENG DM-1701 defective !

Hi Roger, the 8-pin We resoldered the flash chip! Unfortunately, errors still exist. We cannot restore the "Flash" - the USB port is immediately closed. Should we use the 8-pole? Replace flash chip? The code plug can be written into the device, but then the USB port is permanently on/off. 73 Alfred ...

Re: New BAOFENG DM-1701 defective !

Thank you Daniel for your quick reply!

How can I replace the SPI flash?
Daniel, can you give us clear instructions for the repair?

can you make a recommendation as to which modules work best for RT3s?

Re: FYI - GPS
