My phone gets stucked in a bootloop if I start it. The last thing I did was changing the fonts. I replaced droidsans by Segoe ui. Well I already deleted the cm10.zip on the phone and now can't flash it from CWM recovery. What shall i do now?
I read that this procedure here helped others. You should give it a try.
Following the advice from ZnewmaN I am "copy-pasting" the instructions here. The article refers to Galaxy Nexus w/ Android 4.0.2 but you can follow similar steps for other scenarios too.
