I had Rogero 4.50 cfw. We had a family get together today, and I left the ps3 unattended. My dumbass cousin proceeded to update to OFW 4.55. I noticed way too late, it was about 40% done installing (not downloading). I freaked out and just turned off my ps3. Everytime I turn it on it tries to continue installing the OFW. Doesnt boot to safemode either.. just tries install the update.
Is there ANY possible way to halt or cancel the installation to 4.55 OFW or just somehow install cfw 4.55 or downgrade or anything? or am i stuck having to finish the 4.55 OFW installation. Please tell me I have some hope to recover from this without needing to get a flasher.
Oh and if its worth anything, i have a phat ps3 CECHG01.
