Hello, you should visit the usbjtag forums and look for the tutorial. I remember seen a couple of post talking about flashing a motorola CM using the blackcat dongle. Let us know.

[bobbyrkey]

i flashed it succesfully

[jscastro43]

do you have the pinout layout, im trying with flashcat and blackcat but not able to detect

[resellergsm]

is the same that sb6120 bro.

[bobbyrkey]

yes,its the same pinout

I have tried but died on the attempt, i have tried with isp point, without it, the fcat does not detect it

when using flashcat, i use the usual layout for the pins and for the isp point i use pin2 with 3.3v. this works with flashcat on sb6120, sb6121, and sb6141 around 90% of the time. some chips are stubborn and won't detect.
for those i disconnect flashcat, change to pin1 with 3.3v and reconnect. if it still doesn't detect, i disconnect and flip to 5v then reconnect on pin1, repeat for pin2 with 5v, eventually i detect and write to it. sometimes i need to remove the soic clip from the chip and reset it

this has worked for all modems i've programmed except one sb6141 that was undetectable. always disconnect flashcat before changing the volts. i burned out a flashcat by changing volts while it's connected

for SB6141
PIN 1 VOL+3.3
PIN 2 VOL+3.3
PIN 9 VOL+3.3
PIN 10 VOL-
IT WAS Tested in USBJTAGNT
