my friend has a Galaxy S Advanced GT-9070, and he had really bad stock ROM which came built in with the phone,
and i wanted to upgrade his ROM for MIUI or whatever..
So I flashed him CWM and tried some ROMs.
The ROMs flashed properly, but the phone got stuck on the boot logo each time I tried to turn it on.
I did wait a long time, about 2 hours, and I do have experience (successful one) with flashing ROMs on other phones.
Do you have any idea what the problem could be?
Any kind of help will be appreciated.
