(adsbygoogle = window.adsbygoogle || []).push({}); I am on 4.46 rebug DEX and I am trying to downgrade to Rebug 3.55.4 using the 999 downgrade but when I go to system update and click update via storage media it shows 3.55.4 PS3UPDAT.PUP and it is greyed out. And when I click it I get the error code 80029CCA. Plz help me I have tried everything and nothing works.
