Ps3 wont update to 2.40

The way to fix your problem would be to go into settings - go to system update and click on update online if it says u have the latest version than restore your system . If u don't have the latest version then guess what update to the latest version that will fix the problem

the problem you have is not the above the problem you have is with the dodgy update sent out thousands of people all over the world are having the same problem if you go to sony playstation web site you will find out more and sony are working on the fix now and will be sorting out another update to fix this problem with the ps3 update,,

plz rate this solution as i have a whole page of unrated posts, thanks,.

It is because you don't have the blu-ray drive connected that is making this fail. Hook it up again then try to update. If it doesn't update that way try downloading from Sony's site to a USB drive and update that way. If the laser is bad on the drive you may just want to get Sony to repair/ replace it, even if out of warranty as that is still cheaper than buying a new system.
If you cannot get to any menu to tell ps3 where it is to download it.
Then go to System Update but just tell the PS3 to go for an external device instead of looking for it over the internet.

You need to perform a Firmware Update.

hit the X button when selected, or hit too many buttons... PRETTY COLORS...

Instead of updating to 2.42, you should update to the latest version available (currently v2.80). The game probably doesn't work with the current software as the game most likely needs some of the new features in a newer firmware update.

Make sure both the game and system software are updated. The game will prompt you to update when you first start the game. To update the PS3 Software, go to the [Settings] menu and select [System Update]. Then give it another go.

From the home menu, select (Settings) > (System Update), and then press the (X)button.

Select [Update via Internet], and then press the (X)button.
The system automatically searches for and finds the latest version of the update data.

Download the update data.

If a new version of the system software is found, an update is necessary. Press the (X)button to start downloading the update data.Follow the on-screen instructions to perform the update.

Confirm that the update was successful.After the update has been completed, go to (Settings) > (System Settings) > [System Information]. If the [System Software]field displays the version number of the update, the update wassuccessful.
WARNING:

• Do not turn off the PS3™ system during an update. If anupdate is cancelled before completion, the system software may becomedamaged, and the system may require servicing or exchange.
• During an update, the power button on the system front and PS button of the controller are inactive.

First try to update the PlayStation software itself and then update the COD.
Due to specs of PS3 soft none of updates will allow background download. and make sure that your internet connection is uninterrupted, I sugest u to use wired connection rather than wireless, and while update is in progress try to keep all other internet connection requiring equipment offline for smoother process.

Update me about your progress

Good luck

This is a really annoying bug that’s present even in the current version (2.10 as of this post) of the Playstation 3 system software. When I got my PS3 earlier this month, it was using the oldest version, 1.10, but I couldn’t update it because the DNS error was preventing me from getting online.
After searching online for that error number, I came across a few sites that said the PS3’s DNS server needs to match that of your router. I made the appropriate changes to the PS3 and off I went. There was still a problem, though: it wouldn’t login to the Playstation Network, even though it passed the DNS test. Augh.
Some of the more silly answers I found included resetting your modem, calling your provider, telling the PS3 to automatically find all settings, and turning off your firewall. None of these make any difference.
The only option I had left was to download the update to a USB flash drive. This is a poor solution because not everyone HAS a flash drive. (You could probably do this using the 80 gig model’s card reader, though I wouldn’t know about that.) Anyway, here is a simplified version of the directions I followed:
1. Make a new directory in the flash drive named PS3, then one named UPDATE (both must be in all caps).
2. Save PS3UPDAT.PUP to /PS3/UPDATE
3. Plug the flash drive into the console, then from the XMB: Settings -> System Update -> Update via Storage Media
After this is done, you can delete the stuff you created on the flash drive.
Now, you’re using the most recent software and it still keeps giving you DNS errors? The only solution I’ve found so far is to keep trying to login until it works. That may sound like a shitty answer, but it’s the only one I’ve found that works with any certainty. After searching for a good amount of time and trying every suggestion, brute force is the most dependable answer I found.
Update: I’ve been using OpenDNS (208.67.222.222 & 208.67.220.220) for a couple of weeks now with little luck, but some people say it helps.
Update 2: I solved the mystery: spanning tree. Spanning Tree Protocol is a protocol for preventing loops in a network of switches. I had to turn on spanning-tree portfast on the port my PS3 is plugged into. Chances are this solution is completely unhelpful for most people, but I’m putting it up here anyway, just in case.
