    Hello guys,

    I have CECH-2504A on 4.83 i am good with hardware so planning to buy E3 flasher to downgrade it, since i am new to this i have couple of questions.

    1. Can i downgrade to 4.82 and then use exploit to install CFW
    2. What would be the best way to fix e3 clip on nor chip since people have problems with it, it seems?
    3. Do i need to downgrade to 3.55 first or 4.82 + exploit is enough?

    Thanks and regards,
    Magix01

    did you first check to see if ps3 is hackable with minverchk? What you would do is to patch for nofsm and install a 4.83 cfw strait from there. No need to downgrade now like there was in the past. If you decide to go to rebug after that you can simply enable q and a toggle and move up or down freely to any cfw after that. Playerkp420 has an excellent guide, just Google it

    What version should minverchk show if it is hackable since i dont have console at me right now? Does it need to be hackable in order to downgrade it with E3 aswell? Thanks

    minverchk should show a minimum of 3.55 or lower in order for it to be exploited and yes you have to have minimum of 3.55 in order to downgrade with E3.

    You could , but while you have the E3 attached you might as well just patch it to allow CFW there, its the same patch that the xploit would apply basically.
    It depends on exact model and a bit of luck on whether or not you got a perfect clip, If I was you I would try it just clipped on first, that might work, if that doesn't work you could try just putting small bit of pressure on clip with your finger and piece of cardboard, doesn't have to be cardboard, bit of plastic or anything, just something to insulate it as it can get quite warm. Then if that still doesn't work you might need some kind G-clamp with as little pressure on it as possible. Be careful with the clamp, it would be easy to do damage if youre not careful. Really you want to be getting a couple of identical good dumps in a row before you try flashing. Make sure to test your dumps and compare them.
    You don't need to downgrade at all really, you can just patch it with a 4.83 CFW patch and install 4.83 CFW directly. Note your PS3 still needs to have a minimum version of 3.56 or less to be able to install CFW, even though you wont need to downgrade it still needs that to be CFW compatible.

    @DeViL303

    So version can be either 3.56 or less? ISAK.M mentioned 3.55 or less, will check and post back later when i get back from work.

    Thanks

    Yes, equal to or less than 3.56. Sony tried to patch the hack in 3.56 but failed to do it properly (as it was kind of impossible I think) so it also got hacked. Then on 3.60 and above they changed the hardware and added metldr2 which blocked CFW permanently on those consoles.

    The difference is that a minver 3.55 console can be downgraded to OFW 3.55 which is fully hacked, we can install CFW on that like its an official update, just via USB. With a minver 3.56 console you need to apply a patch and go straight to any CFW equal to or above 3.56.

    If your minimum version is ok you don't need to downgrade anymore, use the latest version of PS3DumpChecker and it has a NoFSM 4.83 ferrox based patch so all you would do after check your dumps, patching your dump, then flashing your patched dump, then check agin to make sure all is good, if it is then you can simple install a 4.83 CFW after this, no need to downgrade anymore, unless you really want to for whatever reason that may be.

    Just the modified version of Back up injector, but you will need a PC with BD ROM drive capable of reading and ripping the PS3 BD discs. And only games that are CFW2OFW compatible can be used with this method, there is a page on the PSdevwiki with a list of games that are.

    There is a thread by Inm7 some where on here that will help with this.

    Here's the thread link:

    http://www.psx-place.com/threads/ps3xport-tool-inject-backups-on-4-83-ofw.21448/

    No you don't need CFW or HAN for this but it is a lengthy method to play backups. If you try to downgrade or install CFW on your model PS3 Slim you will brick it.

    I am totally out of luck on this one it seems :) So even if there is ever 4.83 (like 4.82)exploit, this console wont be able to install cfw on it?

    Your console will never have custom firmware unless a method to hack/bypass metldr2 is found

    Just wanted to ask, if i play injected backups online is chance of getting banned smaller than with CFW?

    I know nothing beats official channels for online gaming but the way i see this injection method is really close to being official since not much system stuff is changed?

    I would think a much less chance of a ban than CFW or HAN as the PS3 is not exploit in that sense, just exploiting the a backup method to play games, and as the mounting of the games is the same as PSN digital and they are signed the same way to run.

    Have you looked through the thread I linked for this answer, I only ask because I am unsure myself as I have not got round to testing this yet for my own understanding of the method as I am on CFW. But I have one PS3 on 4.82 OFW that's ready to test various things like this including HAN, I just haven't got round to it yet lol
