For the first time, we have been involved in something truly spectacular

We were the first in the world to test the downgrade from 3.70 to 3:55 on a PS3 Slim (With flash memory, ” NOR “) using the ProgSkeet and patched some files provided by dospiedra, a famous Spanish coder already discovered on the crest of the wave for the method of going back to 3:55 / 3:41 with the PS3 (FAT flash memory “NAND”).

After several attempts, in collaboration with dospiedra, we got to go back from 3.70 to 3:55, enter the factory mode with a simple key to jailbreak, rifleshare a modified version of 3:55 to prevent the SYSCON (the registry in between downgrades) was consulted during the downgrade and now we are happily at 3:55 KMEAW!

With this version of moddata 3:55, you can perform a memory dump today and you can switch on the fly from 3:55 to 3.70 without having to make all this long procedure times: progskeet using it you can go straight to 3.70 changed to 3:55!

Dospiedra said it will release details on the patches applied to the NOR and the update file as soon as possible.

New life for those who arrived too late to enjoy the benefits of the 3:55?

PSPJust yesterday, RoxFox64 met up with Hellcat and Davee who were in the final stages of making their new, signed downgrader. As it turned out, he had upgraded to 6.35 from 6.20 recently and needed to use it, imagine that coincidence! After waiting for Davee to give him the compiled version to test, he was more than happy to see that it had worked 100%!
With this downgrader, it will be very simple, and very safe, to downgrade from 6.35 to the 6.20 firmware!

From the ReadMe:

[What does it technically do?]
It uses the utility/power exploit to gain kernel access and reboots into the updater with a special PRX running. This PRX uses the pspdecrypt functionality to decrypt the updater PRX when needed. This allows the updater to boot in the newer firmwares.
So, in order to use this you need the official update for OFW 6.20 (SPECIFIC TO YOUR MODEL)
Installation is very simple:
Place the 6.20 update in X:/PSP/GAME/UPDATE/
and extract the downgrader’s folder into X:/PSP/GAME/

Why OFW 6.20?
Currently, 6.20 is the latest firmware we have full Kernel access on. This is the firmware you’ll find the absolute most functionality on along with HEN TN-C.

A day many of you have been waiting for is finally here. The folks on 3.42 and 3.50 firmware will no longer have to sit on the sidelines. We’ve been exclusively informed by HolidayCarts, an official PSJailbreak distributor, that the PSJailbreak Team is set to unveil their new website:

To quote the website: “PS Downgrade is a software add on that connects with your existing PS Jailbreak device. In 1 minute or less you can downgrade your consoles firmware to any previous firmware.”

As mentioned above, PS Downgrade is not a new chip, but it is the much anticipated software update to the original PSJailbreak chip. The update will be available for customers who have a valid serial, of the original PSJailbreak chip.

It’s interesting to note, that the downgrade can only be used once. Our source explained “1 time downgrade, cannot downgrade more then once, or to a lower firmware after you choose which firmware”

Another website has also surfaced, This one showcases the following video, offering visual evidence of the downgrade. The site was up prior to any news being posted and uses similar graphics to which leads us to believe it is another official partner.
