[Q]

Hello folks,Yesterday while updating my Galaxy note n7000 to Jelly Bean I mistakely used Galax S2's jelly bean instead of Note's and after installing my phone is not starting,its only vibrating and I cant get into download mode nor recovery mode and what worse is when connected to my PC it does not even detect the phone,how do I unbrick my phone?I am sure there must be a way without changing the motherboard and so.

Please help me out and thank you in advance!
