With the recent outbreak of Downgrader dongles there are bound to be people who push the limits, ie: downgrade using Debug firmware on a retail PS3 like i did, which leads to a BRIICK

You may think that this is a ballsy move, but you’d be sadly mistaken. It isn’t.
I had the unfortunate experience of goosing up my ps3….

The inital install of debug firmware goes without a hitch, untill you turn it back on and you get 5 beeps. Oh yeah, and recovery mode wont save your behind this time.

To fix it, i took the precaution of wiping my hard disk, just to erase any corrupted data. I have reason to believe that it is infact a ballsed up firmware update or downgrade. As even after that it still bleeped.

First i tried recovery, no dice, just kept bleeping always 5 times. then turn off.
After ****ting a couple of bricks, i decided to get my thinking cap on,
and get cracking.

So, I loaded up retail firmware 3.15 on to a usb stick along with the Diag2.self file from Folder 1. as i figured out that it must be some incompatiblity with the fimware update.

Put the PS3 into service mode(put the jig/dongle in the far right port). NOTE: The screen will stay black at all times even if you try to load up to service mode.You’ll just have to do it “blind” so dont panic. You will be able to tell that it went into service mode by the dongle going green, or whatever color yours goes. it will go to standby. Don’t worry as thats a good sign.

Now take out the dongle and place it in the same port you pulled the jig out of. Turn the PS3 back on, and let the dongle work its magic. 4 or so minutes later, the ps3 will go to standby.

Once this is done, remove te USB stick, format it and place the Diag2.self file from FOLDER 2 Turn the PS3 Back on and the USB will blink then the PS3 will go into standby again.

One more thing, NEVER EVER UPDATE IN SERVICE MODE!! YOU WILL GET A RED SCREEN OF EPIC FAIL!!. (as quoted by someone on IRC.) you should only downgrade or reinistall the same firmware you have on your PS3.

The reason why i didnt mention it before is because i hadnt slept for 2 days, so forgive my tiredness.

Turn on the PS3 and you should have a fully working PS3 again.

Goodluck
PS id like to thank The mods, who forwarned me not to do it But hey ive learned something new

*little tut for getting revoked PSN games working again in 3.41.

Update to 3.50 – do the DNS hack, then sign into PSN.(activate your ps3) Download the game, load it. then Downgrade your PS3,(backup first) to 3.41.

Restore the backup onto your drive, now your PSN games should work.* : )
