I was using an lpt cable to flash a 2mb to my sb5100, I don't know what happened exactly. But afterwards when you plug in the power cable all the lights come on for about 3 seconds and go out. They never come back on and the modem just doesn't boot.
I had backed up the 2mb orignal from when the modem was booting, it was Sigma X2. I've tried to reflash that, new boot loader, a differ 2mb dump and everything.. The lights still don't come on once plugged in, other than for a few seconds. I've tried everything and read everything. I now have a blackcat USB jtag and i'm still trying to sort out how to get the modem just to boot again.
Any ideas? thanks so much!
I can still recognize the flash and modem in blackcat or toms jtag... Mannnn
if it's still recognizing the flash, i'd try just flashing the bootloader and try updating via ttl/serial even without that i'd still try the tosp reset trick
I've tried about 20 some times no kidding, with the blackcat usb jtag and with my lpt cable. I can detect the flash no problem in any program. I done some commands with toms jtag utility, and it all recognizes the flash no prob.
But no matter what I do when I plug the power cable in all lights light up for about 3 seconds, and then no lights at all. No activity or any lights ever again.
I've tried flashing the sigma bootloader and everything, I've got a 2mb dump that I've written back and all. It detects my firmware in shwarztekats or wahtever, I just can't seem to get the modem to light up after plugged in for a few mins.
Any idae of EXACT bootloader or firmware to try? Or even an original stock flash to do back to it?
thanks for your help
I got it working, doing what I been doing for 2 days now.. I guess the 7000th time doing it made it work. I didn't have to do any wire trick or any unbrick fix. I redid the flash, bootloader and firmware many differ times. Thanks for the help tho!
one of our modem having same problem: all lights out, accept orange pc/activity
we tried jtag using Tom's utility, even with some online virgin 2mb flash but still no light
it detect good though; do we have to do that many time: "700th"?

Buy a Usbjtagnt, and then use the Poke method, it will revive it.
There instructions on their site.
hi mate, iv revived quite a few of these by doing a quick swap with an unmodified modem.
basically u hook up orig modem with same flash chip,untick verify,detect flash chip once detected swap it over to the bricked one,and write original dump to bricked one,all should be good,worked a treat for me.all i use it parajtag that i made
