Re: DMR issue, red flashes and does ne tx

Re: Wanting to use OPEN GD77 BRICKED My HT and broke 'bootloader mode' :(

Re: Official Radioddity firmware 3.02.04 problem

Pipa, the official FW and CPS not works after the flashing, better use the openGD cps and firmware, now i use the last verions of CPS and Firmvare 11-04-2020 and works well.

Good luck

Re: Release 11th April

Yes, its true, but many times it stops the scan, this make me feel that no works well, sometimes when i press the key the radio makes a reset, one every ten times aprox.
Maybe its a bug, anybody has the same problem?
I have the last firmware.
