I've added a new patch to
post #2 which allows the Reading Settings "Refresh the page every:" menu options to be changed. This should avoid the need to edit the device's configuration file to set values higher than 6.
The patch has three replacement values: Base, Increment, and Maximum. Base is the value of the first menu option, Increment is the value that is added to get each successive menu option, and the menu will end when the value of Maximum is exceeded.
For example: Base=2, Increment=2, Maximum=20 will give a menu that allows you to select any of the following values: 2,4,6,8,10,12,14,16,18,20. The values in the original firmware are Base=1, Increment=1, Maximum=6 which gives the menu options 1,2,3,4,5,6.
This patch seems to work okay on my Glo, but it hasn't had a lot of testing yet, so treat with caution and let me know if you discover any problems.
