(adsbygoogle = window.adsbygoogle || []).push({}); alright, so i have a 3.55 kmeaw PS3, i want to go to Rebug 4.21 , the thing is , i keep getting the 8002F157 error.
everytime i run QA Flag its gives me a black screen and beeps 2-3 times (like it supposed to) but when i got to network setting and press the combination, nothing happens can someone help me find away around this?

UPDATE: i got the QA flag issue fixed. but still get a error when trying to update.

i had the same problem, i downgraded to 3.55 then upgraded to 3.55 v 3.7. then i upgraded to what i was on at the start witch was rogero 4.46 and it fixed it. hope it does the same for you.

everytime i try to install any CFW or downgraders, it gives me the same data corrupt error 8002F157

Are you doing the correct button combo:L2 + L1 + R1 + R2 + L3 + D-pad Down
Is your Blu-ray working?
Did you try updating through SAFE/Recovery mode??

If you happened to get the hidden menu: “Edy Viewer”, “Debug Settings”, “Install Package”
Under Debug Setting navigate to: Debug Settings> System Update Debug> Turn ON.
Try to update either through the XMB or SAFE mode.

ive tried all of that my blu-ray is working also

Try using another QA pkg. Weird that you get the beeps but no secret menu. No secret menu means QA flag not activate.

yeah. well thats what the 3.55 v 3.7 is for. you downgrade to 3.55 cfw, then update to 3.55 v3.7 then you can upgrade to what ever you want. wen i done it i tryed to upgrade without the v3.7 and it said data corrupt. so i install the 3.7 and then it worked.

yeah, debug setting is there without me pressing any combination, ill try another pkg later.

Its sounds like QA is enabled? Try and install 3.55OFW through XMB or Recovery then you can go to any other CFW.

already tried that
