Trying to install a ROM through CWM was not installed and I restart this step
I cannot enter recovery mode.
Nor do I download to do so?
Sorry for my English I hope to be clear
Oh dear God.. You can't get it into cwm settings at all? My suggestion at this point would be to play with holding those buttons and try to get the phone powered off.. Once you get the phone off plug it in the comp holding vol up yo get it in download mode.. I don't believe you can initiate download mode until the phone is completely off..
