I was trying to install CyanogenMod on my un-rooted Samsung Galaxy S II using this installer.
- I installed the app on the phone and the PC;
- downloaded the data for the program;
- plugged the phone and it started downloading;
I followed the instructions thoroughly and the phone restarted and started installing the ROM. First, it showed the "Downloading" with the green Android then showed the blue CyanogenMod man for a long while, then the app on the PC said it failed and I should try to restart my PC or disable the antivirus (already did).
So I restarted my PC. Now it said "If you tried all these things, it's safe to restart the phone". So I turned off the phone and now when I try to turn it on it shows the splash "Samsung Galaxy" then shows a black screen (not off).
I tried booting in Download mode ("Vol. Down" + "Home" + "Power" button) but the result is the same as turning it on.
Resuming the install process fails every time.
How can I revert back to the stock Android or continue the installation?
