I just downloaded the Recovery file and the uncle mtk program and installed those on my xperia C. It was everything ok, I just opened the file with the uncle mtk and i'm in recovery mode. Ok, I had to insert the zip file for increasing my internal space in my sd card, I forgot it so I tried to get back. I can't... And the worst happened, I just panicked and clicked the back up files, I get into a weird scream with only Advanced Backup and Restore, I just can't get of that menu. I tried the volume up and down, I tried to reboot my device but it doens't work, I tried the volume bottom and the power one, I tried the camera one and I can't get of that screen. It only says Advanced Backup, Advanced Back to internal_sd and Advanced Recovery. When I try recovery it says no files found, and when I try Advanced Backup it takes a long time and then error, and When Advanced backup to internal_sd it says ms5, something like that. There's no back bottom in here... Help?
