(adsbygoogle = window.adsbygoogle || []).push({}); I forgot to disablle my spoof on PSita and i downgraded using 3.55 downgrader. It got stuck at 99 percent so i took the HDD out and i restored it. Put it back in and now it tells me to update with anything that is 3.50 or higher but nothing works. It either says "data i s corrupted" or "contact technical support for assistance. A serious error has occurred" Is there any way to fix this?

Try to update with QA Flag enabled.

I dont boot to any other menu besides the one telling me to update via usb. Is there a way to enable QA flag from here?

Nope..
Have you tried to boot in safe mode?
If not, boot into safe mode and try to rebuild system database or something..
If nothing work, you will need to change HDD.

I have tried updating through safe mode. I will try to rebuild database next. If not i will order a new HDD. Is this one okay (You must login or register to view this content.)

I'm pretty sure its not a problem with the hardrive. It looks like you gotten RSOD (Red Screen of Death) Did you try to try to reinstall your custom firmware through Safe Mode?

Well it sounds like it.. this issue is all located on the HDD.

I have fixed my issue. Thanks for the replies though.

How'd you fix it?

I put the HDD onto my OFW PS3 and i booted into safe mode. Then i restored the HDD and then put back into CFW ps3, booted into safemode and then system updated.
