Is there anyone who knows how to delete recently update firmware to reupdate this firmware? A few days ago, I updated the firmware( 4.18) of my pismo. Even though an message that the firmware was successfully updated was followed by my 4.18 firmware update, a problem that had not existed before came up-I posted this problem in this forum. As a way to solve this problem, I want to try to delete this updated firmware.

To the best of my knowledge, there's no way to delete a firmware update, other than to put a more recent update on top of it. I don't know about the Pismo, but on towers and cubes that 4.1.8 update caused a lot of problems with the system being unable to recognize 3rd party RAM sticks. There is a freeware program somewhere on the internet that will cause the system to recognize the "missing" RAM, if that's what your problem is. I think it's called "DIMM First Aid" or something like that. Try searching these forums for the words "firmware" and "RAM"...
