Samsung Galaxy S2 in download mode breaks lsusb
Solution 1:
I've found my samsung intercept is very finicky about USB.
Try another cable? Try another port? Try rebooting? On some laptops it'll only work -sometimes-.
This isn't necessary an answer, but it's just too long to put as a comment. Please look into whether the following will work-
My suggestion is to avoid using Download mode altogether. USB is too finicky and it's not worth the risk. This is what I would do on the intercept. You should see if you can't find something like flashimg that will allow you to flash directly from the phone.
- Get temporary root. (use gingerbreak?) if you don't already have.
- Flash Clockwork recovery using flashimg.bin
- Flash update using clockwork recovery.
