At that manufacture date I would recommend using the CR4 XL. Best boot times and not too many wires. You can get the Cr4 XL for $30-35+ SH most times and regardless of what chip you buy you will need a post fix adapter most likely and a 4GB nand kit. Spend the money and get the latest and greatest and most sites don't sell CR3 lites and if you see any out on random sites they are probably fake clones. Spend the extra $15-20 for something that will be less frustrating than some old chips could be. Also I'd look at
http://team-xecuter.com/ (the non-forum page) and look at resellers to find someone who ships to Egypt. Just seen that is where you live after I posted.
You might need the 4GB nand RW kit or another nand reading tool
You need the CR4XL obviously
You will need the postfix adapter I'd imagine at that manufacturing date. You can optionally but the Corona QSB but if its a 4GB the rest of its useless for the most part.
Tool to remove and lift off x clamp.
Flux, good soldering iron, and read the tutorial.
Its easy tuning most times only using what the tutorial recommends as the switch settings. Look where they place the chip on the board, then keep your wire lengths as short as possible, but obviously and cut and strip them before you solder them to the motherboard so you don't damage anything. Make sure you always read NAND and save a copy before you do any writing to your NAND the first time.
I attached Xecuters NAND guide on corona and how to tell if you need the 4GB kit or can read with a NandX or JR and if you need post fix adapter as well. That way you can buy all the stuff at once and save on shipping costs.
