hey guys a little off topic but seem like you guys are very knowledgeable with e3 flasher.. I have a ylod ps3 from trying to go dex->cex

was having fun and really wasn't caring if i bricked wanted to get a e3 flasher anyways and now i have a valid reason

will it be easy to fix this brick? see that i have the dexflash.bin and the cexflash.bin? i tried using factory service mode to flash back the cex flash to my ps3 and it would never flash it then when i exited fsm it was ylod.. I have a fat nor ps3.. which version of e3 should i get? i'm buying from
here thanks guys and could you possible give me a link for a good e3 tutorial you guys use?
edit: is the limited edition worth it? just prob going to be using it with my 1 nor ps3.. my nand aren't going to see dex lol one is on 4.21 ofw and the other on 3.55 cfw..
