Maintenance Menu

From OESF

The Maintenance Menu is a standard Sharp ROM utility program for performing a system check, clearing or reformatting system ROM, or flashing a new ROM image.

The Maintenance Menu is activated by holding down the OK button while booting the Zaurus (hold down OK until the menu appears).

Menu text is in Japanese. Following is a translation or the menu screens displayed for a ROM update/flash (screen captures obtained from a Zaurus model SL-C1000):

The Service Menu

If you succeed, you should see the service menu -- in Japanese (see Figure 1). [If the service menu didn't come up, you'll have to reboot again. If you are partway through the start-up process, it'll probably be faster to just unplug the unit and take the battery out for five seconds.]

You'll want to choose option 4, Flash/Update.

Flash/Update

Then a Japanese screen will come up asking where you want to install from -- an SD/MMC card or a CF card (see Fig. 2). This screen may appear different on different Zaurii. Choose the appropriate option, and continue. If you get this image (Fig. 3), it is an error message telling you that your Zaurus is not plugged in. It will not flash if you are not plugged into AC power, because if the power is interrupted, the flash may be incomplete and leave you with a damaged system.

Pressing OK will take you back to the previous screen. Make sure you plug your Z in before continuing.

Next, you get a warning screen (Fig 4). It likely says something to the effect of:

Warning: Flashing will erase everything on your Zaurus. Make sure you've backed up first and you know what you're doing. Are you certain you want to do this?

If you are certain, press "Y" to continue.

NOTE: Installing some non-Sharp ROMs, such as pdaXrom's U-Boot boot loader, destroys the Maintenance Menu. The menu utility can be recovered with a NAND restore, though this would destroy the installed non-Sharp ROM.
