Hi Guys
Here is A NooB Tutorial For Installing MiralaTijera CFW 4.50

Step 0:Important Notes

Always Check CFW with PS3 PUP Check [MD5 VERIFY]
Use a FAT32 flash memory that has the files needed to install CFW
Eject any disk you have in the drive because if there is a disc in the PS3,Your PS3 ]will be upgraded with Update File That is inside the game disc
This CFW is installed only on consoles With OFW 1.00--3.55 and All CFW/MFW 3.55 or CFW +3.55 with spkg sig check patched
If you still using True Blue/JB-King dongle or any F@cking DRM Dongle ,Unplug and Then Put it in Recycle Bin and start Tutorial From Step 1
If your console is Spoof to +3.55 Versions ,you do not need to disable it
