(adsbygoogle = window.adsbygoogle || []).push({}); hi i dont know if someone aready had this idea but im wondering if it would be possible to install 3.55 over 4.50 OFW but not with a e3 bc im wondering if we could make the ps3 update 3.55 look like ps3 update 4.53 but wance it installs your on 3.55 instead of 4.53 but keep in mind this could only possiblely work on ps3s that came originaly on 3.55 or earlyer firmware this might be impossible but im wondering if someone is trying this or has thanks for reading my idea

Its not Possible, You cannot UPDATE TO A LOWER Firmware. YOU Need to Either Purchase A Ps3 on 3.55 and Install a CFW, or Downgrade and Yes you do NEED a Hardware Flasher.
