It takes a lot more than that for some people. Just because you can do it easily and properly doesn't mean it's '1-2 mins at worst'
The process DOES take nothing but 1 or 2 minutes at worst though. I wrote a small tutorial and posted it once or twice in this very same thread and I seriously doubt that by using it, the deal would take more than 2 minutes to anyone.
I'll leave it over here again, just in case.
1) Open NUPS Patcher
2) Click on "Apply an UPS Patch to a file"
3) Choose your ROM where it says "File to Patch"
4) Choose your .UPS Patch where it says "UPS Patch"
5) Choose "Ignore" where it says "If file is invalid".
6) Click on "Patch".
After 1 minute at worst, a message saying "Patching has been done" will popup, that's it, go and have fun.
