Solution for redsn0w "Usb communication problem" error

Unlike cryptic and non-informative iTunes Error Codes, jail-breaking utility redsn0w do offer useful information to diagnose possible issues. A common error encountered with redsn0w is "Usb connection problem", but despite the clear message and obvious solution to fix USB connection between the device and computer there could be other reasons for the error.

While the very first thing you need to check when encountering this error would be a good working cable and a properly functional USB port, this error can also be caused because of newer versions of redsn0w not compatible with Apple iPhone 3G. For me using older "redsn0w_win_0.9.12b1" fixed the issue, so go ahead and download redsn0w 0.9.12b1 from the links posted below if using iPhone 3G and facing this error.

the experts on this site:

say that the latest can work on 3gs. in fact, they say it directly in that article. so what is your take on that? thanks.

This is what I experienced, and How I solved it - Also, I was using Apple iPhone 3G. If the other one works for you use it, its just the same software different version.

if what other one? that is the point, nothing is working. no matter what i do, i get the usb communication problem error. i even went out and bought a new usb cable for my iphone, because some person said it could be that. i need a real solution! i don't want an older version of ios. i have 4.2 now. i want either 6.0 or 5.1. i have almost every redsnow there is, and i have the dl ios 5.1, 6.0 and 6.1.3. they say they can do it on the 3gs, so someone tell me how to get pas this ridiculous error.

The other one is the redsnow version you mentioned when you wrote "the experts on this site.....say that the latest can work on 3gs". My suggestions :

a). Use another computer.
b). Reinstall iTunes.
c). Try with various redsn0w versions.

don't really understand why i would need another computer when i have a top rated gaming laptop, with usb 2.0 and 3.0. they work just fine. however, maybe i will reinstall intunes. i haven't actually tried that yet. thanks.

Have a 3G in Brazil that was having trouble with the newer redsn0w ... the older version just worked ... THANKS A MILLION ... !!o!!

Thanks a lot!!!! You are fantastic!!

older version worked like a charm thank you my good sir

Thank you... it worked for me... i tried everything before, then I got this version of redsnow and did my jailbreak.

thanks, it work with redsn0w_win_0.9.12b1
