(adsbygoogle = window.adsbygoogle || []).push({}); Here is a SIMPLE guide on how to bypass the firmware. You must currently have firmware 3.30 to use this method. It is possible to do with lower firmwares.. Also, we might be able to downgrade doing this, but I'm not risking corrupting my HDD.

Needed:
PS3 Proxy Server You must login or register to view this content.
A PC and PS3 using Same Router
(old) update-list.txt

PREPARATION:
Create a new .txt. document named "ps3-updatelist.txt" Put this in it
Code:

# US
Dest=84;CompatibleSystemSoftwareVersion=3.3000-;
Dest=84;ImageVersion=0000a4b4;SystemSoftwareVersion=3.3000;CDN=https://dus01.ps3.update.playstation.net/update/ps3/image/us/2010_0422_6bdf1b2409d705a0136c40746c62e85d/PS3UPDAT.PUP;CDN_Timeout=30;

1. Set up the PS3 proxy server. Put your IP in the box, also make sure to check the PS3 box and hit start.
2. Go to the Replace files Tab and in the left box put
Code:

You must login or register to view this content.

3. In the right box browse to your ps3-updatelist.txt and click it.
4. Sign In, it should not ask you to update firmware. Congratulations, you are playing online with your PS3 on firmware 3.30!

This is possible without the proxy server! If you have a parental control router, redirect the updatelist URL to the URL of an older updatelist! They are uploaded all over, so they are easy to find.

i take no credit for this and sorry if this was already posted

never thought it could work :O

can not fix? hack patch I updated Never love 3.15. ^^

Maybe here in the near future but as of now no!
Google SSL and TLS Encryption and you will see why a MITM(Man in the midde) is not possible.

Just like Shiver has already said. This does not work.

I can "Not" go online with my old FW PS3. Yes I have older FW on one. So I can say for fact it don't.
