Since yesterday, when I try to flash a RAK board, the firmware file is not replaced in the device window, but also appears in the folder. The erase file for a factory reset is also displayed in the folder in this way and has no effect.
With the same setup I have so far flashed all of my RAK devices (10-12 pieces) without any problems.
but with the software presented for resetting the RAK boards
“Tera Term” I cannot select the serial interface at all.
The RAK 19003 Base Board flashed blue and green at the beginning. Now only the red LED of the charge and i trie this with two 19003 boards and 3 different RAK4630.
I tested all 4 RAK4630 cores and couldn’t flash any of them.
I noticed that the drive is not named RAK4630, but: FTHR840BOOT?
After a bit of googling I found a tip to update the bootloader:
My attempts to load the bootloader somehow don’t work.
I’ve already tried various things.
The COM port should also be correct.
Do I have the correct bootloader?
Or does anyone else see an error?
cmd:
C:>adafruit-nrfutil.exe --verbose dfu serial --package WisCore_RAK4631_Board_Bootloader.zip --port COM37 -b 115200 --singlebank --touch 1200

Possible causes:
Selected Bootloader version does not match the one on Bluefruit device.
Please upgrade the Bootloader or select correct version in Tools->Bootloader.
Baud rate must be 115200, Flow control must be off.
Target is not in DFU mode. Ground DFU pin and RESET and release both to enter DFU mode.
What didn’t work on the PC I managed to do on the Surface
Maybe it was the COM settings.
But couldn’t get it to work on the PC yet
Maybe it will still help some people with the same problem
