Title: Yet Another Bricked C1000
Post by: wiredog on May 23, 2005, 10:30:00 am

Different symptoms than described in this thread. (https://www.oesf.org/forums/index.php?showtopic=12733)

We're playing around with custom kernels to do hings with loopback filesystems (mainly mods to loop.c and loop.h) so that we can store user data (bookmarks, mail account config, and the like) on a loopback.  

The loopback is mounted to /home.

Mounted the loopback, started a few other programs, started the mail program, and the Z gave a low memory warning.

Then it died screaming.  Screens rotating, error messages, so we rebooted.  It shut down, but wouldn't reboot.  Hangs at the Sharp screen.  B+D boot hangs.  Reflashing the kernel (option 4 in the maintenance menu) hangs.  Any other option in the maintenance menu just boots it, then it hangs.  EX: Normally, when restoring to factory state, you do option 3, then option 1.  On this Z you hit option 3 and it boots.

wiredog,

i guess it's time for a NAND-restore  

[EDIT ]
For a reset to factory defaults you need the AC
adaptor plugged. No AC = Warning and reboot !

Working on it...

The guy who's playing with it has hacked together an updater.sh script that got him to the console, now he's trying to rebuild things by hand to the point where NAND restore will work.  We're thinking that we may somehow have overwritten part of the flash that stores all the maintenance menu functions, which is why they're acting weird.
