Have nand mod, flash emunand to sysnand, use startup button sequence to delete update, re-read and write back to emunand. solved.
If you have the 9.7 nag you have to wait for 9.8 update...I made a post about it a couple of months ago. There are a couple of ideas in the thread but not sure if they are successful.
Method to remove update nag from Emunand?
As long as you have a backup of your emunand it boils down to just being nagged once a day. If you or someone else updates your emunand, just load the backup. If it nagged every time you exited to the home menu that would extemely annoying. I am married so I can handle a nag every now and then.well having a nand mod sounds like a good idea but besides that solution?
