I've got mine Galaxy S2 which I was rooting, changing rom a lot of times, never had any problems.
My friend gave me his phone to do a root on it, I was doing everything like always, and when I tried to install the root and restarted, the phone it's not turning on at all anymore. Tried to take out the battery, change for another one, but nothing.
Do you think that USB JIG can help in this situation when phone is not responding at all or maybe you have another ideas?
Thanks in advance for any help.
