Upgrading galaxy s2 GT-I9100T 4.0.3 to 4.4
Status 6 often refers to a problem within the updater script. Be sure to save it in unix format. I mostly use notepad++ to edit those files. 
notepad++ > edit > EOL conversion > UNIX format

Also make sure there is an empty line on the end of the script. So if the script has 112 lines, the 113 should be empty.

Status 7 means that the rom is incompatible with your device as it checks the device model. Thats why you have to delete the first line in your updater script. Be sure to delete the whole line (with the semicolon).
