Re: Backup battery problems

It’s like a month old. I’ve been really busy with work so I didn’t use it that much (only to try the firmware). I’m gonna leave it on for the day today to see if it charges and if that solves the problem. But I remember that a couple weeks ago, I forgot to turn it off and it was on for like 12-ish h...

Re: How does one start porting the fw to another platform?

Yes. The CPS will be fine communicationg to a PL2023TA, but you will need to manually select the port, as the CPS looks for a device named OpenGD77. I’ve been messing around with a multimeter and I found out that the USB wiring for this radio is quite interesting. Turns out that the MK22 connects t...

Re: Backup battery problems

Hi, I'm having a similar problem. If I don't turn on the radio in a couple days, all my settings are gone. Isn't there any way to store the settings in a non-volatile memory that doesn't rely in a battery, like with the GD-77, etc.? When I don't use my DM-1801 in months, all the settings are still t...

Re: Alternative firmware for UV390?

I am having problems with flashing OpenGD77 with my UV390. My radio is Hardware version V03.00 . And the serial number starts with S/N:2008N00***. Can you confirm that your radio is newer than mine? I've had a chance to check it today. My hardware version is V03.00 too, and the S/N is 220624 (looks...

Re: Alternative firmware for UV390?

But strange why this other operator has problems installing the firmware. Perhaps some older version of hardware with incompatible bootloader That’s weird, it should work. Even the official TYT releases are exactly the same for both radios (well, actually they don’t post any firmware files for the ...

Re: Alternative firmware for UV390?

I own a UV390 and as far as I know, it’s identical to the UV380, only with a waterproof case and an extended battery. I’ve been using the OpenMDUV380 alphas for a couple weeks and so far had no problems. If more people verify that the UV390 works, we could even list it as supported. The OpenRTX deve...

Great! Thank you so much for everything. :)

I’ll try everything as soon as I have some free time. I’m sure I’ll be able to make it work.
