January 7, 2011 // 2:37 am - Update: KaKaRoToKS has now confirmed that the PS3 3.55 downgrade is no longer possible, tweeting the following: "sad news.. downgrade worked, but not reliable, only works with one of Xtse's ps3s, but can't reproduce it.. I'm going to look for another way. nope, it only works on one machine, even if same model, it doesn't work on it. No idea what's different about it..."

Today KaKaRoToKS has confirmed via Twitter news of PS3 downgrade success from version 3.55 to 3.41 PlayStation 3 Firmware.

This confirmation comes just days since his PS3 Custom Firmware surfaced and under a month after the PSGrade free PS3 Downgrading hex codes arrived for version 3.5 and below consoles, followed by Sony revoking lv2diag.self file_1 and patching PS3 downgrading in the PS3 Firmware 3.55 update.

Here is his Tweet, to quote: "First downgrade from 3.55 to 3.41 successful, Thanks to Xtse! Method not yet ready for the masses because of risk of bricking the ps3."

Currently this is all the details available, but we will update this post as more surface as always!

I prefer wait for a cfw and I think I'm a not alone in this case.

You're certainly not alone on that one.. But on the other hand there are people who accidentely upgraded... so they'll need it.

Slightly more info on the subject. Also Mathieulh is a douche :S

[15:57] < +anos> how kakaroto and xtse managed to downgrade?
[15:57] < +Len> who’s Mathieulh?
[15:57] < @Mathieulh> rehashed pup
[15:57] < @dwrfcrank> Len: some wannabe
[15:57] < +Len> lol
[15:58] < +anos> yea but with only pup version it wasn’t working
[15:58] < @KaKaRoTo> Mathieulh, more complicated than that
[15:58] < +Len> he’s ok in my book icon wink KaKaRoTo Successfully Downgrade v3.55 PS3 Console To v3.41
[15:58] < @KaKaRoTo> but it was mainly just luck

[16:35] < +daVIDAvid> the downgrade is a brick/unbrick?
[16:36] < @Matt_P> no.
[16:36] < @Mathieulh> kakaroTo just overwrite the syscon eeprom with 001
[16:36] < @Mathieulh> not even sony recovers from that xD

[16:54] < @Mathieulh> kakaroTo there are at least 2 other ways to downgrade that I know of, dunno which one you use though
[16:54] < @Mathieulh> geohot, find another ecdsa fail for us !!!
[16:54] < @Mathieulh> lol
[16:54] < @KaKaRoTo> Mathieulh, share that info and i’ll tell you if you got it
[16:54] < @Mathieulh> it’s not yours
[16:55] < @Mathieulh> I dunno how YOU do it, I just know I have ways to do it of my own
[16:55] < @Mathieulh> which sadly imply using sony code in both but meh

Yes this is a good and valid point but for people that are on 3.55 that don't have JB devices are awaiting a custom firmware for their version, I myself have 2 ps3's one for JB and one for PSN for online play.

However i recently upgraded the HDD on my JB PS (PS3 SLIM released with fw 3.5 160gb now with 1tb hdd) and i use an original ps jailbreak dongle, ps jailbreak left the scene so im more or less screwed till my X3Max turns up in the mail which will be another 2 weeks living in AUS as i can not aquire the files to flash my current dongle to downgrade.

So fingers crossed someone comes up with a cfw for 3.5+ soon. (TBH im sick of the power off power eject process for JB mode anyway. Sorry if my post sounds like a ramble to much rum tonight.

I hope that too. Got myself a Slim 160GB and a E3 Cardreader, before i noticed that i got a shitty CECH 2504a which isn't downgradeable atm

if you already have 3.55 then when you want to install 3.41 in recovery mode it asks for a firmware equal or greater as 3.55

i don't have downgrader usb stick so i could only try this method
