Goodnight everyone ..
Here I have a G300 from a friend who asked me to do a root and install a ROM better ..

I'm a little scared because the phone is not mine, and admired because I've done this multiple times on different phones and similar never happened to me ..

You say you rooted and installed CWM, but you didn't mention updating the baseband - if the phone was running gingerbread and you've been flashing ICS roms, then it would probably act as you describe. If you want most ICS roms to work, you need to update the baseband, either with an official ICS update, or you could try the recent thread with flashable zips, tho that's new enough to be considered experimental.
Maybe just check the "like you're 5" tutorial in the sticky.

You need to flash the official ICS so your baseband changes to 2030. Then unlock the boot loader, root, and install a recovery. Now you should be able to flash your chosen ROM :)
