Translation of the original post @ Elotrolado.net:
Varicela and Luckymas and I have managed to install CFW 4.30 E3 in these kind of consoles.
In addition, we want to add that these patch are already valid for installing 4.30 CFW E3 from any OFW not higher than 4.31 or in consoles with a firmware below 3.55, skipping the downgrade process, the use of a dongle and the factory method.
At the moment, this only works on NOR memories, the NAND ones will be updated once we test it.
The following patches are needed: Patchv1 Three Musketeers
There is no need for a dongle but you need to use a flasher for getting our dump. Several tutorials are available at Elotrolado.net to perform this with progskeet, E3 or tensy.
Once we get or dump, we need to patch the following offsets:
patch1 : OFFSET 0C0010 LEGHT 6FFFE0 patch2 : OFFSET 7C0010 LEGHT 6FFFE0 patch3 : OFFSET 80000 LEGHT 20000 patch4 : OFFSET A0000 LEGHT 20000 patch5 : OFFSET 40000 LEGHT 20000 patch6 : OFFSET 60000 leght 20000
TESTED ON SEVERAL 3.56 OFW FACTORY CONSOLES (WE SUPPOSE THAT FACTORY OFW 3.60 CONSOLES DOESN'T WORK BUT WE HAVEN'T TESTED IT)
WE ARE NOT RESPONSIBLE OF ANY MISUSE OF THIS METHOD.
INFORMATION TO CONSIDER:
- OFW 3.56 factory Playstation 3. You will not be able to downgrade from 4.30 but you can upgrade with future patches
- These patches are only for installing CFW 4.30 E3. Any other CFW will show you "Corrupted data" if you try to install them from the Recovery menu
