Downgrade PSOS 3.6x mediante modchip Infectus
Notizia parecchio succulenta per i possessori di PS3 FAT con PSOS aggiornato alle versioni 3.6x (per la precisione 3.60, 3.61 e 3.66): sarà possibile, mediante modchip Infectus, eseguire il downgrade ad una versione precedente del firmware aprendo così le porte alla possibilità di installare un CFW.
Di seguito, le parole di dospiedras1973 hacker che ha reso tutto questo possibile:
Citazione:
Hello, I’ve been working on this project about two months nowsince I’ve gotten to work as public so that everyone can use,this tutorial is for consoles with 256MB NAND flash does not mean it does not work in 16MB in itself is changed almostthe same in those with normal flash, but because even I havemy fat ******g 16mb 80GB I have not been able to neither prove nor verified.
Nougat (the phrase I owe to some forero around here that I really liked the expression):
With INFECTUS flash0.bin and we get our nand flash1.bin asin the tutorial to repair bad lukin nands do the same process until we get our dump flashfinal.bin 256MB
nand we open this with a simple hex editor and look for this part editor
“00 00 00 00 00 00 00 00 00 00 00 00 00 6F FF E0”
ay you will see that just under a very similar line, I find this datain the offset 000C0020 may vary according to the nand andthe party starts here:-D
EVEN replace that line with the file if you use the hxd1patchcos.bin get in the first 0 of the line -> right click and paste writing before you have to have an open 1patchcos.binhxd in hex and copy its contents to can paste .[ps3hax.net]
“00 00 00 00 00 00 10 10 00 00 00 00 00 00 10 10 00 00 00 00 00 00 20 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 02 40″
and in the same way as the first patched patched this alsocojemos 2patchtrvk.bin pack the file and replace the entire contents including the “00 00 00 00 00 00 10 10 00 00 00 00 00 00 10 10 00 00 00 00 00 00 20 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 02 40”
then we take the option we use reescramble flowrebuilder thisdump so we rebuild our flash0.ECC.bin and flash1.ECC.bin
and flash the result, when you finish you will notice that the PS3 now has a nice on but black screen, it cojemos ourfactory jig to put it into service mode and put it in factory, thenthe typical cojemos lv2diag of yore and the pup you please
(NOTE: the first pup that metais will stay in the console as the minimum version that you can downgrade then, if you want tolose 3.55 to 3.41 then you will have to put the pup up to 3.41before 3.55 or 3.55 will remain in that if cost will not rewrite thedump again to downgrade to lower the pup that you put thefirst time.)
then you put your factory lv2diag to leave the service and you’re good
Note: this applies to repair the brick Waninkoko NAND NOTDONATED plates even sem-001 (tested) (and stepdowngrade xD)
Thanks to:
all channel # irc-hispano darkps3 for supporting me for so long
to donate the INFECTUS austaquio32 to achieve to continuewith my project
to Nodial2ne paid for the help locating files in the nand
to robs1 for helping throughout the process with ideas tomake this possible
and everyone who was patient and not by private haunts mexD
Occorre però specificare che questo metodo richiede oltre a delle ottime capacità nell'uso del saldatore, in quanto i punti sulla nand sono particolarmente ostici, anche l'uso di una serie di file contenuti in questo pacchetto RAR: [url]http://www.multiupload.com/V2154YEX8M[/url].
Per lo schema potete fare riferimento a quello presente su Infectus.biz nella relativa sezione PS3.
Questo metodo, consente di interfacciare e riprogrammare la NAND al PC, e quindi se la vostra PS3 risultasse brickata da un aggiornamento non andato a buon fine potrà essere facilmente sbrickata.
