Playing around with a TRB140 - it was on firmware TRB1401_R_00.01.06.1 and I followed the instructions to upgrade the legacy firmware by attempting to flash to TRB1401_R_00.02.03.2_LEGACY it all seemed to go through fine but now it won't boot and the signal strength indicators are flashing the following.
4th light blinks twice really fast and then all 5 blink twice with a 1 second gap.. the cycle continues ad nauseum.
Is this flashing an error code that can be found somewhere ?
I've tried restarting, power cycling, factory resetting, remove / install sim etc but nothing seems to take it out of this cycle (except factory reset which blinks all 5 for hours so guessing it's not doing much)
The usb connection doesn't show up in my OS anymore, and direct ethernet doesn't seem to work either.
Anyone else ever had this problem ?
