In this tutorial, I will show you how to jailbreak your PS3 Slim Or FAT(which their minimal versions need to be 3.55) without having *dongle* or any E3 Flasher. Before telling that this operation can brick your PS3 system, please acknowledge that like if we were using E3 Flasher, you must know if your system flash memory is NOR or NAND, if your PS3 model are compatible from jailbreaking. If your system is not compatible with the E3 Flasher, then it's not compatible for this method so use at your own risk ! Credits to the method developers at the end of the thread.
Dongle : A USB device which has a primary function : Flashing the NOR / NAND Flash Memory. A dongle is NOT a USB Mass Storage Device.
#####NON - RESPONSIBILITY ADVICE#####
If, in the process, your PS3 won't boot anymore or just RLOD or RSOD, I should not be taken responsible or liable for the material damage to your system.

Tutorial Part One Completed //
//Tutorial Part Two : Installing Custom Firmware
6 - Now that your flash memory is flashed, make sure that your 4.82 CFW is located at the following directory : /PS3/UPDATE/cfw-file.PUP, and rename the .PUP file to : PS3UPDAT.PUP so it should look like this : /PS3/UPDATE/PS3UPDAT.PUP using your PC
7 - Reconnect your USB Storage to the rightest USB Port then, in the XMB, go to Settings, System Update and use Update via Mass Storage. Don't check Power off when update completes, it's a waste of time The PS3 should detect your CFW but don't worry, your PS3 Flash Memory is patched, CFW will be successfully installed. There is a 1% risk of the CFW installation failing or having PS3 failure. I shall not be taken responsible for any damage caused to your system.
8 - If your CFW has been installed successfully to the PS3, then now you are free to install multiMAN and other homebrews to the PS3 Brewology website !

- Domination - Click on Single Player and click the 2nd Comic "Industrial Zone". Select Logistics Nightmare and Choose "B" as your monster(he's red and black). Simply destroy the marked buildings by mashing R1 and L1 and O when you're close to them. 
- Inspector Monster - After completing the above mission, go to Monster Lab in the main menu and simply scroll over everything. Then exit and the trophy should pop.
- O.C.M (Obsessive Compulsive Monster) - Choose the first level in the 2nd comic for this "Industrial Strength". Choose "B" and flatten the map. There will be orange text over buildings when you fully destroy them saying "building destroyed". This may take you a few tries but I believe in you. Use your roar using L2 to stun the enemies for a few seconds so you can go up to them to eat them using R2, but don't do too often because you don't have that much time. I actually died once doing it and never ate anyone and was able to spare maybe 5-10 seconds. 
- Megabucks Monster Club - Go to any of the later destruction levels and level as many buildings as you can, you have to get your PROPERTY DAMAGE score above 850K. 
- Twinkle Toes - Go to create a monster and focus on Speed and Jump, choose 'Around the Houses' in the 'The Suburbs' comic and avoid as much destruction as you can. DO NOT jump on the marked buildings, just run up and rub against them to clear the marker. When running up to them, let go of the analog stick or else you'll crash into them.
