Hello! Like it says in the title I have a problem with rooting. All I did was to upgrade to official jelly bean. I searched for like 3 days continuously in French, German, English and all I have found was some info about what I should do. So I know that I have to flash a new CWM and that's probably why I can't flash ROMs. I get into Recovery mode, I select "apply update from external storage" and then it says with red : "E:failed to mount /sdcard (No such file or directory)". I found another method, with adb, tried it and failed, it says can't read file or open it, I'm not sure. With odin I tried so much CWMs... I can't number them. None of them worked. So I'm asking you, I'm mad to upgrade my android, to flash cyanogenmod, and I can't. Please help!! And please tell me how I know what version of cwm I need? I mean it's from Baseband- I9100PXXLS8 or Build number-I9100PXXLSQ? Please help! And don't tell me to search please!
