(adsbygoogle = window.adsbygoogle || []).push({}); so i downgraded my ps3 from 4.70.1 rebug to rogero 3.55 downgrader.it wont let me go back to 4.70.1 rebug , i cant install anything .im qa flagged. when i try from the xmb it says "update data of version 9.99 or later can be installed on this system" and when i try from recovery mode i get an error. i've tried 3.55 OFW, rebug 3.55.4 999 downgrader , rogero 3.55 v3.7 and many others. nothing seems to work. what is it this time ?
p.s. i've read previous threads on this matter , but nothing actually helped

Kmeaw 3.55, try it and make sure you enable QA Flag correctly (I do it from Rebug Toolbox)
Download it from this forum: You must login or register to view this content.

you probably know but I am going to tell you in case you don't. to make sure you are QA-flaged hover over network & at the same time with the controller press: R1,R2,L1,L2,L3, & down on the D-pad if you are flagged propper you will get the extra debug options under the network option. also make sure you format the usb fat 32 & folders are named propper ALL CAPS (PS3-UPDATE-PS3UPDAT.PUP) also you eject the usb & do not just pull it (sometimes you get corrupt files pulling the usb)

any help ??

have you tried to reinstall the downgrader you used? i had this problem i had to use diffrent downgrader habib ithink i used then kmeaw 3.55 then install rebug 4.70

Go to 3.55 OFW then go to 3.55 Kmeaw. That should solve your problem.

i have tried that and also reinstalling rogero downgrader but none of that can be installed
