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.

you need to update the system. then it will install the new update. or it could be the smudges on the disk
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.
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.
