(adsbygoogle = window.adsbygoogle || []).push({}); Im mostly posting this to say I didn't like it, I think PS3ita 4.50 is better.
If you like being on the newest version of things.. an update is out.

**IMPORTANT (READ IT):
If you’re on CFW PS3ITA COBRA 4.50 DEX install this CFW from recovery menu.
There is no danger to install it from xmb, but sometimes ps3 after copying the PUP inside the HD does not restart properly and stays on a black screen.
The workaround is just turn manually off/on the ps3 and install the CFW will start automatically.

Heres some FEATURES
- Addded new_core.
New_core replaces sys_init_osd.self and launch System Manager at boot of console.
It was developed by Estwald and based partially in the work of MiralaTijera. For more information: You must login or register to view this content..

- Added System Manager
System Manager adjusts fan speed depending on the internal temperature of PS3. It was also developed by Estwald.
We added support to CFW 4.55 DEX and one function that allows to change the speed of the system manager through the program *CFW Setup v2 (see note below)
If you have a PS3 at risk YLOD the system manager will save your console! Use it!!

- Added change of console id at boot of console.
Through the program *CFW Setup v2 you can set a new console id that will be applied automatically each time you start the PS3.
Useful for unban your PS3.
If you not imposted any console id, the console id is change from DEX to CEX. This allow you to connect to PSN.
Work in all Boot Mode (Debugger Mode, System Software, Release Mode).

A lot of The options such as System Manager are great additions, or at least seemingly So, But there are some reports of Games not Booting on it, or Redirected to the Recovery Menu, Also no Backup Manager Works for it at the moment, except the latest Update of Iris Manager and Gamesonic, i Believe .
When They manage to Fix some Issues, i can consider Updating to it.

I couldn't load games on this CFW. It would just boot me to recovery menu. So I went back to 4.50.

that was my problem no games would start... :/
EDIT: that was from disks too

if They fix that, and a few other issues, i would probably update.

For the most part as of now, I would recommend staying on the 4.50 update as they have a lot of issues to fix.

yeah if they fix all that it would be great

I feel like they really rushed the 4.55 version

I definitely have to agree. They've left out multiple features and mainly the MAIN features that are needed to make up a nice CFW Version. They have lots of bugs and issues that needed to be inputted...
