Looking for some help here from the community. Some of you might remember me from the SBHacker days and I hope all is well.
I'm looking for some noisy bootloaders for the later docsis 3.0 broadcom modems. I have an SB6182 that I'm trying to flash either shelled firmware on or a noisy bootloader, at least. The 6182 bootloader doesn't allow me to select boot images via pressing 1, 2 or p during startup. I tired flashing the 6180 bootloader on there for shits and giggles, but it refuses to boot with it.
I'll be posting how to get serial on that modem on the usbjtag forum, but if anyone is interested I'll post it up here, as well. I was playing around for a couple of days with my oscilloscope to find the correct points. I was also able to dump firmware if anyone wants them. I don't know what they are at this point, but I can let you know if there's any interest in it.
I know that I saw someone with some shelled firmwares and some fun orange modems, but I forget if they were 6180 or a 6182, I'll cross reference that with the usbjtag forum. If someone has 6183 shelled firmware and noisy bootloader, I'd be more than elated, as well!
Thank you kindly!
hello, here I cut the boot of a Motorola mg-7550 bcm33843 should work is noisy ... I also have dump sb6183 but I do not remember if it has a bootloader noisy, if you have one to have console you only have to ground the SO pin when load the Nonvol known as emergency mode, this is known!
if you have modem backups already named or others send me PM maybe I can give you a push and tell me if you need a noisy boot
