It is best that you wait a little loner and if it is still stuck on 99% then I would recommend you quite the update and do it again but if it doesn't work after the second try then contact the support team on playstation.com and they should be able to help from there.
you need to update the system. then it will install the new update. or it could be the smudges on the disk

Just where would you get the information to update it from without the internet. The system can not be updated without it being downloaded and then loaded into the PS3. I'm not trying to give you a hard time it's just that you need the internet just to read this answer. Sony PlayStation network has a section devoted to system software updates and support. They have PC update method and Disc update method as well as system update method. A link to this information has been added under related links I have another suggestion for an easy update method if you have a friend with a TV and a WiFi connection. Just take your PS3 over to there house and hook it up and download and update. Because after reading the other methods this seems much easier for someone without the internet. Also you will need the internet just to download the information.
You can not revert the PS3 update
Yes, you can use a flash drive to update your PS3. To do this, download the system update file from the PlayStation website, then create a folder named "PS3" and a subfolder named "UPDATE" on the flash drive. Place the update file inside the "UPDATE" folder, and then connect the flash drive to your PS3 to perform the update from the System Update option in the settings menu.
It takes a few minutes for each step if you have an online connection
no you will be updated to 5.56

You can only update the PS3 manually either by initiating it from the System Update menu in the XMB (via internet or from an insertable storage media), or responding to an update message when you login to your PSN account. Either way, the update shows its progress on your screen as it happens, and turning your PS3 off in the middle of an update can cause a lot of problems (loss of data type problems).
No, but there are system updates which apparently crash your PS3. SO I would recommend you stick to the original Sony Updates and wait for some reviews of the update before updating because some people claim that their PS3's were bricked by the 3.21 system update.
PS3 is on Update 4.21 released on July 6, 2012. Update 4.11 was February 16, 2012. System Update 3.10 was November 19, 2009
Well first you have to update your system
By asking the administrator.
put the jailbreak on your jump drive then plugin your jump drive into your ps3 then turn on your ps3 then go to system update and click update via storage media agree to terms and install then your done.
You might need to update your PS3 if that is what you have. To update offline put in your game and a message will say you need to update to version. To play online go to settings and select "update system" to update it.
