OpenGD77

ah ok.
so while using the CPS software it writes over eeprom and flash.
that makes sense now.

Use the OpenGD77 CPS to restore the flash and eeprom backups. Then use the manufacturers update program to reload the firmware. ok thanks. but I really don't understand this logic. can someone explain me ? When we want to use OpenGD77: 1. we first overwrite the firmware with unofficial OpenGD77 FW ...

ok. mcu not needed for rollback to original firmware.
what about the eeprom and flash files ?
when and where shall I use them when going back to original fw ?

I'd really appreciate any help on this...

I don't understand where I will use the eeprom, flash and mcu that I backed up.

thank you

Thanks. With 1.2.3 it works but not very stable.
I am losing voice especially if the remote party talks long.

I found it once you draw my attention to that.
Thanks.

Thx.
Somehow I could not see that option. Although I have read that part of the manual

I have installed TCPUART on phone and USB is connected. It sees the GD77 on USB as "NXP SEMICONDUCTORS MCU VIRTUAL COM DEMO"
it is configued to listen on tcp port 2000
but I don't know if it is the correct version.
I installed from Google Play

it says v 1.3.1 (20200410_091351)

thanks. my contact is a group call (TG-DLTR) and it is available in the RX list named DLTR so I guess that's not the problem. now I changed TS to 2 as you suggested but I sitll can't receive voice what else should I check ? actually when I see people talking on the TG , on my phone screen (Blue DV) ...
