JaiCraB and ps3mrenigma have released an app that gets us one step closer to custom firmware. Their app, entitled Mount Alejandro, enables writing to the dev_flash, by mirroring dev_flash to dev_alejandro and making dev_alejandro the active one. As everyone should know by now, dev_flash are where your console’s firmware files are stored after installation. Please use caution when using this app since it deals with your PS3′s flash.
Download: Mount_Alejandro.zip
FLASH WRITER ENABLER:
————————
This application allows the mounted one of the /dev_Alejandro unit. This unit is a mirror of the /dev_flash unit, being this active one also.
The /dev_flash unit lacks permissions of writing, useful to read like towards formerly, nevertheless the new one, IF it has writing permissions.
It is for this reason, that we do not become people in charge of the evil use that can be given this application, to the used method, etc. As end users YOU ARE RESPONSIBLE FOR the USE THAT YOU DO OF THIS PROGRAM IN YOUR MACHINES!
To have it in account before wanting to manipulate firmware, archives XML, etc.
Happy Xmas!

P.S Because the name of Alexander? Who knows, equal has something to see with some of us…: P

My jaw dropped when I saw that hint at the bottom. What else could it mean besides that Dark_Alex is in on it?
Long live DA! This is so awesome!

This is great news indeed. I can't wait to see what comes of this

I am a tad confused about this. I had thought that we could already load firmware off a USB drive successfully (at least a large portion of us can :P). We can alter the files on it and load up our own modified XMB for example.
I guess I am asking, what does this change? It seems like now we are able to write to dev_flash, but if we are unable to edit the .rco files on a USB drive, what makes us think that this will lead to CFW in dev_flash? Unless there are limits to USB firmware loading. Any information would be nice, thanks.

I was thinking the exact same thing, still though - once we can edit these files and get into the nitty-gritty, atleast we can permanently modify them.

This will not be true, right, and if so, miserable, but also to re-pay

Yeah, I thought about the Alejandro thing. After all Dark_Alex was Spanish too... I was wondering if he would try out some PS3 hacking.

I couldn't find the original from which this article was translated for you to quickly do a better translation - I tried but I'm rushing to get to work just now. However even without seeing it I STRONGLY suspect ", IF it has writing permissions." was originally "Sí tiene permiso para escribir" - it should carry an accent (but laziness means not everyone writes it). The reason that is important is it completely changes the meaning to something more like "DOES have writing permissions" or "REALLY/ACTUALLY DOES have writing permissions" - no "if" about it! however I'd rather read the original spanish just to be on the safe side as I'm inferring from the mistakes in translation.

if dark_alex gets on the scene sony might as well kiss their asses goodbye and admit defeat

nice, write to dev_flash... i smell cfw before christmas, specially if the master key rumors are true...
12-13-2010

cool,sounds good.now for some idea of what we can do with it
Nice one pimpspter,i was just ranting about bad english on forums causing even more confusion and a really bad one hits the front page lol.
a proper translation would be very welcome.thanks to you if you do that mate.
************* [ - Post Merged - ] *************
This application allows the mounting of the unit / dev_Alejandro.
This unit is a mirror of the unit / dev_flash, still is active as well.
Unit / dev_flash no writeable useful to read the old way, but the new SI is writable.
This is why we are not responsible for any misuse that can be given to this application, the method used, etc.
better translation from psx scene
As end users ARE RESPONSIBLE FOR THE USE OF THE SOFTWARE WILL you do IN YOUR MACHINE!
Taken into account before trying to manipulate the firmware, XML files, etc.
Happy Xmas!

PS Why the name of Alexander? Who knows, maybe it has something to do with any of us ...: P

Does it redirect the dev_flash permanently or must we launch tha application each time we turn on the PS3 ?
If this is permanently, it is really nice !

As far as i understand it,
this program allows you to write to /dev_flash
but because of the /dev_flash being read-only it mounts /dev_flash to another location (/dev_alejandro),
just to give you the write permissions.
so when writing to /dev_alejandro you in fact write to /dev_flash

for it to work you need to flash the hex with peek and poke enabled.
Then install the PKG and press O to enable and it will say "SUCCESS" and you write to your hearts content, but be careful if you **** up, it will lead to yet another brick
And i saaaaaaaaaaave the day again XD To undo, just reflash the fw, it only works on 3.41. Do not use if you dont know what youre doing XD [like me] :P

FINALLY! we are gettin some where and even though im eating noodles during this post i can only hope that this cfw makes it way online before xmas otherwise no xmas wishing 4 any of u.....

I think I understand the general idea...but I just wanna get clear on somethings...

1. Is /dev_flash in the ps3 internal memory or on the HDD? (i believe it to be on the internal chip.)
2. is the mirrored /dev_flash mirrored onboard or from usb? If it is, in fact, from the ps3 itself, couldn't we add the payload info to that mirrored directory? so that the payload would load automatically? or am i missing the point of this?
i'm not a programmer or a hacker by any means.... id love to try/get into it... but i'm not exactly sure how to get started... anyone wanna point me in the right direction?

I think this is good news, but all I would like from this is linux usable again, homebrew and maybe loading of PS2 games off a external harddrive. I do not want the Playstation 3 hacked to the point no dev wants to make new games for it and it dies like the PSP. Yeah I know hacking is a port of it, but it does not have to be to the point of killing it.
Oh and if DA is part of the PS3 hacking scene then it will be interesting to see what he bring to the scene. Would be nice to see what the system would be able to do because of his work. All we can do now is just wait and see what comes of this news.

I've followed the link to PSgroove which contains the same bad translation I've seen around the place.
If someone provides me with a direct link the original spanish I'll translate it propperly for you!

There needs to be a huge obvious pop up reminder before using this app! Remember to test the firmware with a USB firmware loader first. There is going to be a ton of bricked consoles when kids and others not tech savvy attempt to use it!
I'm not sayin' this isn't amazing, but there's no turning back with this one.
PRACTICE SAFE FLASHING!
Heh, see what I did there.
12-13-2010
02:44 PM
actually, there is turning back.
service mode :D

does anyone know which payload i should use w/ psfreedom to use Mount_Alejandro? thought id ask before i just started trying to use it dont want to break anything
12-13-2010
06:13 PM
it works with every payload as far as i know.
12-13-2010
08:48 PM
To add.. Back up your PS3 HD AND Test it first.
Just.... KNOW WHAT YOU'RE DOING KIDDOS! If you dont know what the flash is/does or associate the word with flash drive, dont mess with it.
Mah rant is over.

This is a quick translation of the main post from the page that someone linked for me above (quick as I have a report due for tomorrow and am doing an alnighter so shouldn't actually be translating things - but it's amazing the amount of energy one gets when there are tasks to avoid doing!)

sorry let me correct then, we need, to have hermes (no spoof) meaning hermes v4b, and PL3 with peek and poke.
12-16-2010
08:04 AM
so will one of the peek/poke PL3's work from the new PL3/Hermes 4B with 3.55 Spoof?
edit: i guess no.
hmmmm...
but say i put a spoof payload on after , will the changes to flash still be ok?
