Galaxy S3 Stuck on Boot Screen after Flashing a ROM
Hi, I'm new to these forums and need some help!
I just rooted my Samsung Galaxy S3 i9300 yesterday using the Odin ver 1.85 tool and it was working perfectly all day. I was doing a little research as to how you can use custom ROMs and so I decided to give it a try.
I downloaded the ROM Manager application and flashed the ClockworkMod Recovery that comes with it before attempting to flash a ROM. I then proceeded to download the CyogenMod ver. 9.1.0 that comes with ROM Manager as well. I made sure to make a backup of my current ROM on both my internal and external SD cards and then went ahead and flashed the Cyogen ROM using the application. I also chose to wipe the data/factory reset before confirming.
After the process was done, the phone rebooted with the Cyogen logo and it was all working fine for the first 2 minutes. Then all of a sudden while going through the new ROM's screens, my phone rebooted showing the "Samsung GALAXY S III GT-I9300" message and with a little red "!" mark on the top left. It stays like that all the time. I tried turning the power off and taking out the battery but it always goes back to that screen immediately after.
I'm able to go into the ClockworkMod recovery by holding the volume up+power+home buttons but I see the following lines below:
ClockworkMod Recovery v18.104.22.168
E: Can't mount /cache/recovery/command
E: Can't mount /cache/recovery/log
E: Can't open /cache/recovery/log
E: Can't mount /cache/recovery/last_log
E: Can't open /cache/recovery/last_log
I've tried wiping the cache, wipe data/factory reset, and wiping the dalvik cache options but it doesn't seem to work. I also tried flashing the ROM again from the SD card, but when I try to do it, it says "E: Can't mount /sdcard/". Same thing with my external SD card.
When I plug the phone to my computer, it doesn't seem to detect my device either. Is my phone bricked and will I have to get a new one if this is the case?
I tried to do some searching and this thread seems to be similar to what I'm facing but not quite as the methods suggested by the users are unknown to me: http://forum.xda-developers.com/show....php?t=1500947
I appreciate any help I can get!
