Is there any method to load Backup from APP_HOME ??My bd is broken (logic component is recognized )

[Kyuubi93]

My PS3 is a CECH-2504B and its datacode is OD could anyone tell me if it's safe for me to install this CFW, thanks in advance and i wish everyone a nice day.

I am pretty sure the consensus here is that this does not work with metldr.2, right?

@Kyuubi93
This is all of the info I could find when it comes to what models came with it:

First you need to say if you are currently on 3.55..

The "WMPDT355?" link in my sig will figure out your datecode for you.

If my app says you can downgrade to 3.55 then you can possibly instal 4.21 CFW... but tbh I wouldnt touch 4.21CFW until its stabilised.

As if anyone will listen though.

The brick wave continues.

@DEFAULTDNB was wondering if you know if we need the original param.sfo for this 4.21cfw because multiman has changed mine to 3.55

Thanks in advance

Using MultiMan 4.08 and bd-mirror activated in all of then.

Most likely.

I would revert any changes I made to the files.

I always keep my original untouched file copies as:

eboot.bin.bak
param.sfo.bak
<whatever.sprx.bak

as standard just in case I need to revert.

Ok I don't have backups for param.sfo but I do for eboot is there a way to revert by editing with HxD. Would be nice if deank put in a function to edit param.sfo for 4.21

I think you just need to alter the version number back to the original.

Use the ps3 backups compatibility wiki to find the version number and use a sfo editor to put the correct version number back in?

There must be a database of param.sfo's online? or maybe a reader to read the file from within a back up download link?
