Here are the guides for installing the latest 4.xx CFWs 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 your PS3 is not hackable, you CAN'T install CFW at all. Your only option would be to install an ODE to be able to run homebrew and backups.

If you're already on CFW, you can always start with the 2 (optional) steps below before installing the CFW of your choice:

Dump your NOR/NAND Flash:
Download and install the latest version of multiMAN (CEX) from the link above, plug in a FAT32 formatted USB flash drive into the right USB port, launch multiMAN under the Game column 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
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.

Dump your eEID Root Key:
This has to be done only once, while (and if) still on 3.55/4.50 CFW, just in case you want to ever switch to DEX in the future without having to downgrade back to 3.55/4.50 CFW to dump it.
Download and install the correct eEID_RKDumper.pkg for your CFW version (3.55/4.50) > Unplug all USB devices > Launch eEID RKDumper under the Game column. It will black screen for 10-15 seconds, beep 3 times and reboot automatically. Now FTP to your console and retrieve your Root Key/PCK1 (48 bytes) from /dev_hdd0/tmp/eid_root_key if on 3.55 or /dev_hdd0/game/FLTZ00010/USRDIR/eid_root_key if on 4.50. Once you retrieve your Root Key, you can delete eEID RKDumper from your XMB as it is not needed anymore.  

Rebug 4.46.1 LITE:

This CFW can only be installed on top of CEX FWs. If you're on a DEX FW, you have to convert to CEX before you can install this CFW. If you don't know what CEX/DEX is, you're most likely on a CEX FW.

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- Install Rebug 4.46.1 LITE from XMB:
Download the latest Rebug LITE from the link above, verify the md5 hash with @DEFAULTDNB 's PPC+, rename the PUP to PS3UPDAT.PUP, put it on your FAT32 formatted flash drive in PS3UPDATE, 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!

2- 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.  

Rebug 4.46.1 REX/D-REX:

If you're on a CEX FW, you have to install the REX Edition. If you're on a DEX FW, you have to install the D-REX Edition.

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 REX/D-REX from XMB by following the guide below:

1- Install Rebug 4.46.1 REX/D-REX from XMB:
