Finally, I decided to post my guide to installing the latest Rebug CFW on your PS3.
If you're on OFW higher than 3.55, you CAN'T install CFW directly! You need to check if your model is old enough to be hackable (older than June 2011). If you're lucky enough and it is hackable, you can use a hardware flasher (NOR Guide | NAND Guide) to dump your 3.56+ flash, patch it and re-flash it before you can install CFW using the guides below.
If you're on 3.55 or lower OFW, or a hardware flasher patched 3.56+ OFW, or any 4.46 or lower CFW, you can install Rebug 4.46.1 LITE from XMB by following the guide below:
1- Dump your NOR/NAND Flash (optional):
If already on CFW, install latest version of multiMAN CEX, plug in a FAT32 formatted USB flash drive into the right USB port, launch multiMAN under the Game column and go to mmOS > Press
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
This creates a backup of your NOR/NAND flash so that you can recover using a hardware flasher in case of a (highly unlikely) brick. It is recommended to do it every time you upgrade/downgrade your CFW just in case something goes wrong.
2- Install Rebug 4.46.1 LITE from XMB:
Download Rebug 4.46.1 LITE 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, NO game is mounted and that you DON'T Update via Internet or else you would risk installing OFW >3.55!
3- Enable QA:
Go to Package Manager > Install Package Files > PS3 Hard Disk and install Rebug Toolbox. Launch it under the Game column, go to Utilities and change Toggle QA Flag to Enabled. This is to ensure easier and safer downgrading.

Notes:
- OFW 4.55 has been released, make sure you don't accidentally update. You also need a spoofer to connect to PSN (with ban risk).
- Make sure you use mM 4.46.00 or higher because older versions are not compatible with this CFW.
- Make sure you install the Rebug Toolbox pkg included inside Package Manager because older versions are not compatible with this CFW.
- Make sure you use reActPSN v2.27 or higher because older versions might not be fully compatible with this CFW.
