The main reasons why TPT Helper appears not to work are:
1. You need to unzip the TPT Helper boot files into a directory 'image' at root level
2. You need to hold down Vol+, Power and Menu (that's the one in the middle)
I know because I've done both of these repeatedly.
Skate 2b is OK but you can do better.
To take full advantage of Lalit's exdcellent 'size zero' CFX3 ROM you can use the 'Create your own TPT' function.
Make sure that the image directory is absent before you start.
Then set the Cache prompt to 2 and the System prompt to 165, which all the CFX3 and the stripped Gapps need.
This will leave 273MB free for apps and data.
This option will auto-unzip the TPT files and create the 'image' directory
You can use the 'Check the image directory' function to verify before restarting as above, which should give you 2/4 matches.
I hope that throws some light on the problem.
