We'd need to hear some some more people who bought new Non-GPS RT3S radios, to know for sure that TYT have changed something.SA0BUX wrote: ↑Thu Jan 26, 2023 12:31 amI wonder if 2105 in the serial number could be YearMonth ?
If so ,those having problems is older than the one with GPS.
My GPS equipped RT3S has also 2202R03S11 in the beginning of the s/n and I bought it in 2022, the "seal" over one of screws says 2022 7
The only other report was from someone who seemed to be unable to upload the firmware at all, which was probably a DFU driver problem, and eventually they stopped responding to my questions.
As OpenRTX works on VE2NCK's radios, and that firmware will be using the same encryption key, as found by the MD380 Toolz guys, its unlikely that the problem is the file encryption.
Possibly something in the GPS code in the firmware is crashing, but I don't think the firmware crashing normally results in the radio going back into the bootloader, normally if the firmware crashes it just ends up appearing to brick the radio, as it does nothing and does not respond on USB, until the buttons are held in at the side to enter the bootloader
