Hi everyone. I have a PSP on 6.61, I had already followed this guide: http://hackinformer.com/PlayStationGuide/PSP/tutorials/how_to_install_661_infinity.html I already instlaled the 6.61 modified firmware, am Im on step: Step 6: Setting up the Bootloader Config The issue is that instead of ME CFW which I had installed, I selected the PRO CFW... now the psp boots into a black-screen and shuts down. How can I get back into the Bootloader Config so that I can select again ME CFW if the PSP does not boot... w/o the SD card either. ======== NVM I got it.. I randomly pressed HOME while booting, and it booted with out any cfw.
