Not sure this belongs in General or development.
I have written an APP for my HTC Rezound to do the following
1. Enter the 4636 hidden menu
2. Enter the 778 hidden menu (still working on this one)
3. Power off phone
5. Reboot to recovery
6. Reboot to bootloader
7. List the partitions
It is in the Google Play Store as HZutils.
Nobody has yet downloaded it, tested it, nor rated it.
P.S. It does display an ad. If you click on an add once in a while I will get a few cents.
