First, it's not my CFW.
Second, my info is definitely not wrong, it has been proven to work by me and many other users who followed it properly.
Third, stop swearing.
Fourth, I don't know what you're doing, but you're definitely doing something wrong for it not to work. I asked you what are you trying to install it on? but you didn't answer. How could you have done steps 2 and 3 correctly if you haven't managed to even install the CFW yet??

Make sure the flash drive that you're using is formatted to FAT32.

No, just install Rebug 4.41.2 from XMB on top of your 3.55 CFW by following the guide below:

1- Make NOR/NAND dump (optional):
Install latest version of multiMAN (4.40.00), plug in a FAT32 formatted USB flash drive into the right USB port, launch multiMAN under Games and go to mmOS > Press [O] on any file > Open in HEX viewer > Press [SELECT] > Press [START] > Export GameOS LV2: Select No > Export HV LV1: Select No > Export FLASH: Select Yes

2- Install Rebug 4.41.2 from XMB:
Download Rebug 4.41.2 from Rebug's website, verify the md5 hash, rename the PUP to PS3UPDAT.PUP, put it on your FAT32 formatted flash drive in PS3\UPDATE, go to System Update and Update via Storage Media. Make sure there's NO original game disk in the drive and that you DON'T Update via Internet or else you would risk installing OFW higher than 3.55!

3- Enable QA:
Install Rebug Toolbox from Package Manager, launch it under Games, go to Utilities and enable QA. This is to ensure easier and safer downgrading.

yo read my last comment plz dude

Check your spelling, maybe you're missing/adding a letter somewhere in your file/folder name.

yh i checked it over 900000 times lol

Make sure you downloaded the right file and checked the md5 hash.

how do i check the md5 hash???

So you haven't checked the md5 hash! I thought you said you were following every step of my guide...
