Everything functioned since June 2021 for about one year. - 3 Weeks ago, i wanted to update the device. no chance... :-(
Firmware update higher 00.06.09.2 was not possible. Checksum-error. - I repaired the firmware via bootloader procedere.
No GPS-Menue (see pic).
No repair via RMS because of fault activation possible.
Serial number, product code, batch number, hardware revision in device-Informations are blank.
I could send the serial-number of my RUT955 in a personal message.
THX and regards
