Voy a dejar aquí toda la información al respecto, cuya fuente es psx-scene:
New Updates and more information Update #1 has addition information in
BLUE. Software downgrading back to 3.55 is possible you can view that process below in Update #2. Thanks to
Rogero and
Tortuga-Cove for this information.
PS3 Developer
Rogero known for his other CFW (such as no-check Downgradable FWs) & Backup Manager. Has made use of the recent lv0 keys that have been leaked an released. Soon after Bluedisk CFW was cracked the
lv0 keys for 4.21 were leaked in the wild. So that paved the way for new CFW.
Rogero CFW can only be installed on a PS3 running 3.55v1.00 changes- This is a 4.21CFW spoofed to version 4.25 to allow SEN access
- It can be used as a normal System Update from any 3.55 OFW/CFW/MFW
- It was tested using a hardware flasher and no bricks or any problems at all were encountered
- It can run games signed with Keys up to version 4.21 without any Eboot/Sprx patching needed
- Games must be loaded from Disc Icon (with Original game in BD) and not from app_home
- Current 3.55 homebrew application can't be loaded on this CFW, applications must be re-signed properly.
- Downgrading back to 3.55 is always possible using hardware flashers and will be tested soon using software methods.
UPDATE #1(New/Updated Info in
Blue)
ATTENTION:1- This CFW doesn't have LV1 checks disabled and can't be installed on Downgraded PS3 consoles unless you have Dehashed/Reset Syscon Properly (if you're not sure about your PS3, Dehash it anyway to avoid any risk) Link ---->
Dehashing Tutorial
2- Always make a NOR/Nand dump using multiMAN or memdump before installing this CFW to have a recovery backup in case of any bricks.
Having a valid NOR/Nand dump is an essential step before upgrading, because you will always have a way to recover (using hardware flashers) when you have a valid dump.
** A Hardware Flasher alone without a valid dump cannot fix your bricked PS3 **
3- It's always better to have QA flag set (leave it Enabled) on your PS3 for safer upgrading/downgrading operations. Link ----> [color=#FF0000]toggle_qa.pkg[/color]
4- Always use the Recovery Menu while installing this CFW to avoid possible bricks (XMB update works, but Recovery Menu is safer).
5- TrueBlue CFW users must update back to OFW3.55 before installing this CFW to avoid possible bricks.

Update #2Downgrading back to 3.55 is always possible using the following steps :- Download the 4.25 downgrader PUP ---> 4.25 Downgrader Size 176MB (184,595,263 bytes) MD5: 49d80e07fc1f5ca1b0840e02e94635db
- Rename the downloaded file to "PS3UPDAT.PUP" and put it on your USB in: "USB\PS3\UPDATE\PS3UPDAT.PUP"
- While on Rogero CFW4.21, go to System Update from XMB and install the 4.25 downgrader CFW.
- Start the PS3 into Recovery Menu (or use Condor Updater for Slim consoles) and install "Rogero CEX-3.55 CFW V3.7" (from Recovery Menu, this is important)
- Once the install is finished, you're now back on Rogero CFW3.55 v3.7 ( from here it's better to dehash again before installing any other OFW/CFW 3.55 )
This is exciting news but lets not jump the gun just yet. Rogero is a trusted developer but details are thin on what homebrew can be run such as multiMAN, Emulators ect.. Not known at this time if you can go back to 3.55. So just beware that this CFW may be ahead of homebrew and homebrew may need to catch up. However this is great news!!!
Update:
multiMAN is running but other homebrew need to signed for all other homebrew. Hopefully we see some tools for this process soon.
