Hi D3m0n,
My older BCUSB V1.4 was damaged as my computer can't find it. So, I purchased another new one which is V1.8. I just remember...When I used the V1.4 to flash the SPI flash, the software continued to read/write at the SPI flash tab even though I removed the ISP pin. When I first connected the v1.4 with the modem without using the ISP pin, only receive and send LED's couldn't go out; that is, if I push the ISP pin on the R362 spot, all of the LED's went out. As I was a novice, I forgot to continue to push the ISP pin, but the software continued to work. I don't know why and this flash process took me 2 hours to complete at the SPI Flash tab. As for the BCUSB V1.8, if I remove the ISP pin during the flash process, the BCUSB will not read/write unless I push the ISP pin on the R362 spot. It's so weird that the older BCUSB could read/write without using the ISP pin.
After that, I removed the clip from the modem and powered up the modem, the receive and send LED's were still on. So, I guess this problem has something to do with my older BCUSB which was damaged later.
Now, the SPI flash can be flashed with the BCUSB V1.8 without issues, but I can't make sure the inside memory does not have problem.
