DC8 5.55 OFW PSP mod by RedBull
This allows you to test the dc OFW 5.55 firmware from Sony (EYE IS AN OFW, NO CFW).
- Copy the update folder in PSP-> GAME
- Creates the eboot to 5.55 yourself with PBP unpacked by example and put it in the root of the memory renamed to 555.PBP.
- Put the eboot of 5.00 and put it in the root renamed to 500.PBP.
- Run our software.
Already in the menu of the DC, do not press the first option (Install 5.00 M33) and to actually install the firmware 5.55 with the modules M33 and ipl,
it would have a brick. However, if you want to test the firmware 5.55 official press in the second option (Install 5.55 OFW) and this will install correctly.
With this DC OFW 5.55 can be installed in flash, and emulate 5.00 M33-4 from the memory stick.
If you want to have installed the 5.00 M33-4 in the flash, take the resurrection.prx of update folder and copy to TM-> DC8-> kd replacing by the existing one. Then in the menu, select the option "Install 5.00 M33".
