(adsbygoogle = window.adsbygoogle || []).push({}); v1.09 Details and Changes
- Compatibility problem with some Slim models (CECH-25xx) is now fully fixed.
- XMB Icons problem from in-game PS button is now fixed.
- Loading games from App_home Icon is now fixed.
- Many other fixes from version 1.00 for a better performance and added stability.
- It was tested by hundreds of testers on all PS3 models (FAT & Slim) and no problems were encountered.
- It can run games signed with Keys up to version 4.21 without any Eboot/Sprx patching needed
- Games can be loaded from Disc Icon (with Original game in BD) and from app_home (Disc-less, but not all games).
- Current 3.55 homebrew applications can't be loaded on this CFW, applications must be re-signed properly for FW4.21.

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 ----> You must login or register to view this content.

2- Always make a NOR/Nand dump using multiMAN or memdump before installing any 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- The QA flag must be always Enabled on your PS3 for safer upgrading/downgrading operations. Link ----> You must login or register to view this content.

4- Always use the Recovery Menu while installing this CFW to avoid possible bricks (XMB update works, but Recovery Menu is safer).

6- Please Check the MD5 of the downloaded PUP file before installing any CFW to avoid possible bricks.

7- DO NOT HAVE DISC IN PS3 WHEN UPDATING FIRMWARES..As the PS3 will take the UPDATE from the DISC First.

8- You need to already be on 3.55 to install this. Installing from any firmware other than 3.55 will simply not work


Updating from CFW4.21 v1.00 to the CFW4.21 v1.09 should be done using the following steps :
1- Proper Way ( CFW4.21 v1.00 --> CFW3.55 --> CFW4.21 v1.09 )
---- Downgrade back to ver3.55 using the guide above.
---- Once on Rogero CEX3.55 v3.7 you can update again from Recovery Menu into the new CFW4.21 v1.09

2- Alternative Way ( CFW4.21 v1.00 --> Recovery Menu --> CFW4.21 v1.09 )
---- You can try updating from CFW4.21 v1.00 to CFW4.21 v1.09 from Recovery Mode first.
---- If it didn't work, then you'll have to use the first Proper Way ( CFW4.21 v1.00 --> CFW3.55 --> CFW4.21 v1.09 )

have you updated to this??

any problems?

no problems at all, i went to 3.55 OFW first then to this (all through recovery)

though there have been reports of some phats bricking, slims are fine

Any ideas which fats, mines cechc03 mines the first gen can go back to 1.0 firmware

from my understanding the original 4.21 cfw (NOT this updated version) was fine for all phat ones and was risky with the slims.. but after looking about today rogero has said for phat users not too update to this updated version of 4.21cfw...

v1.09
Fat models
CECHA - Working
CECHB - Unknown
CECHC - Working
CECHE - Working
CECHG - Brick (only seems to affect G04)
CECHH - Brick
CECHJ - Working
CECHK - Most likely working (similar to checj)
CECHL - Working
CECHM - Working
CECHP - Most likely working (similar to checl/m)
CECHQ - Most likely working (similar to checl/m)

looks good to me

cechB01 here,
I had to update via xmb, because recovery kept putting me back onto 3.40, so thru xmb update i got 4.21 on there. So I got 4.21 on, and multiman 4.08 (rogero4.21cfw support) but when i try to load games I cant get any to work.. tried sonic legends 1st cuz it is old, got black screen.

Tried puss in boots (original unpatched) just got past psmove screen then put me back to xmb. Then I tired RE6 (unpatched), and it gets stuck in multiman verifying game. Any detailed instructions on how to get the games to run would be greatly appreciated.

also maybe I didn't dehash properly?? I never had to downgrade but I used the qa toggle pkg anyway (at rogero's request) just to try to be safe. can anyone at least confirm that I halfassed did this right? if I can get multiman to run, then I'm obiviously not bricked right? so where did I go wrong? thx!

also I believe i just went from kmeaw 3.55 directly to 4.21 rogero, could that have done it, because some posts says do kmeaw3.55--->rogero 3.55cfw v3.7--->rogero 4.21 cfw?

i will try RESI in a bit
if you want to stop the verifying on multiman, go to settings and press triangle, then choose advanced options and turn the verifying to off. That might work

any 3.55 signed games arent gonny work anyway, simply use the 4.21 resigner for those or use the originals
if any blackscreen u can try load using SELECT+X for some

then others have said transferring all games to another harddrive caused them to start working

Does this work with slim Cech-2501a now? Is it safe 2 use on this one?

i wish there was one for 4.21 +
