So I've been trying to update my radio for the last 6 months and I've tried everything besides replacing the radio itself, I've used 2 Sandisk usbs, 1 pny usb, and now 1 Kingston usb and none of them have worked. My radio is stuck on the please wait 3-5 minutes, and an all white insert update usb. I don't know why it keeps rejecting my update because every single time it always stops and gives me the error sierra wireless bolo failure. I've taken it to a shop they said it's bricked and I'll have to replace it for 1200 dollars. I regret even attempting to update it that long ago and I don't know how to fix it any other way or test a previous version. Does any one have any tips or anything?
