    Well i researched for like 2 weeks and used like 3 different guides, compared them and went with the safest route and took advive from all 3 guides that seemed to match.

    Basically (off the top of my head):
    QA flag console with toggle qa by rebug its a pkg
    get eid_root_key with eEID_RKDumper.pkg
    dump cex flash from latest multiman, backup cex flash at least a few times on different drives
    use cex2dex gui to use eid root key to patch cex flash to dex
    apply dex flash via multiman
    install 3.55 dex firmware
    install 4.21 dex firmware

    (thats basically all i did havent went back to cex yet dont plan on it yet)

    hi all

    Double-Click (tap) on the DEX TargetID-modified dump renamed to have ".EID0.NORBIN" or ".EID0.NANDBIN" what does TargetID mean ? i have CECHA12 NAND

    DEX targetid modified dump is the one you should of made in cex2dex.exe when you load your cex flash dump then eid_root_key to "patch" cex dump to dex. target id is console specific info about your cex to make it dex; like region etc. US, UK etc eEID_RKDumper.pkg is what gets this info from your console.

    Yes CECHA12 is NAND flash, so save as my-DEX-flash.EID0.NANDBIN, EIDO.NANDBIN is the important part and that you remember its the DEX flash not CEX flash.

    Anyway i used name my-DEX-flash.EID0.NORBIN in multiman and it worked BUT you use NANDBIN

    EDIT: Since your on NAND make sure to QA toggle your console FIRST, then use dex355 firmware first when you're in DEX. If you ever want to go back to CEX use rogero firmware

    hi all pro

    This guide you have to install CFW355-OTHEROS++-SPECIAL.PUP. i wonder if i install this PUP all game data,PSN game,... will be erase or not ? Because CFW355-OTHEROS++-SPECIAL will reserve 20G for OtherOS ,is it right and so internal HDD will be format ? So i have to dump my flash in Kmeaw 3.55 or OFW 3.55

    Otheros is not needed anymore thats what eEID_RKDumper.pkg is for. cant dump in OFW cause you cant use multiman, install eEID_RKDumper.pkg etc use Kmeaw
