I used a slightly different method, which i think is easiest, and the best:
1) Copy the three files from the zip to your phone's memory card.
2) Open a file browser like X-Plore and KEEP IT RUNNING.
3) Install and run HelloCarbide, go to options, then choose menu1. Keep pressing yes until it closes.
4) Switch to X-Plore and copy installserver.exe into the "c:\sys\bin\" folder of your phone.
5) Restart your phone.
6) Install ROMPatcher.sisx and enjoy all the freedom that ROMPatcher gives you.
Download this zip for all the needed files:
NewHack180608.zip
ROMPatcher allows you to use various patches, like to get rid of active standby text, leaving just the icons, plus many more. Also lets you enable and disable caps, therefore no need for the caps on / caps off app, which means you don't need CProfDriver_SISX.ldd either, as ROMPatcher includes it's own driver in the app itself, making it easier.
There are many patches that you can use with ROMPatcher available on Symbian-Freak.
