My ARCH GPRS won’t flash firmware, tried windows xp, windows 8.1, the binaries from the AN11305 on windows, mac and I compiled the xcode project.
All to no avail.
The unit connects ok on all platforms, I see the CRP DISABLD drive, I see a firmware.bin created 23-1-2008, modified 6-2-2009.
Whether i delete the firmware.bin and copy a new firmware.bin or use any of the utilities, the results are the same.
After reconnecting after a seemingly successful flash, the firmware.bin is the original from 2009, so in the end the flash was unsuccessful.
I am grateful for any help!
