Please don't do that. Don't send people to other forums from here. Nobody does it on other forums, so why would you here?
nadsrokr, flashing is a good idea :-) You get more out of your phone, more speed, more features etc. But, it's risky. Just risky, if you do it right it's not even that ;-)
You can flash any firmware to your phone.
But, before anything, you need to flash noRSA bootloader (your version) and noRSA CG31! After that you can switch to any firmware (MonsterPack).
If your phone doesn't start after flashing (stays stuck in bootloader) - flash noRSA CG31 again
