Suddenly my GT7.7 3g+WIFI tab stopped booting. I tried to to install he rom again and previous roms but that failed. I tried using ODIN to restore to stock and that failed. Looking at the format messages under CMW it says it skipped formatting data. I tried to manually mount it but it wouldn't work. Can anyone help me? It seems that DATA is corrupted or something and it won't allow any ROMS to boot.
