Problem Getting Into Maintenance Menu

[noromamai]

yup, me again...

after installing all kinds of shit (including getting jap handwriting and proper keycode.tbl) i thought i'd make a nand backup of my zaurus (sl-6000l with jap stock rom) in case something happens.
i do the usual stuff, sticking something small and pointy into the reset hole, hold down m+d and then press the power button and all the time keeping m+d pressed. nothing happens.... the zaurus does it's normal boot routine.
i open up a console type reboot and hold down d+m right away, nothing happens, doesn't even reboot. but the mail led keeps flashing.
unlocked the battery, press m+d keys, relock battery, press power button.... normal boot routine...
all this with and without AC adapter, no difference.
i can get to the normal service menu by holding down power and ok. but you can't backup from there.

any suggestions?

did some more ersearch into my problem...

isn't there a way to use dd to make a full NAND backup which can be used to to flash the zaurus via the maintanance/service menus? i know you can back up each partition with dd, but not sure if the same can be done for the whole NAND.

noromamai,

isn't there a way to use dd to make a full NAND backup...

there's another way. The SHARP people implemented a way
to create a NAND backup even if the display is defective.
Here we go:

- Have the SL-6000 switched off with battery inserted and AC plugged
- insert an empty CF card >=128 MB in the SL-6000
- Press and hold the "A"+"B" keys and tick the reset switch

Now both LEDs should light up for a moment. The green LED will flash
while the backup runs. Don't turn off, play with the ac cord or do anything
while the green LED is flashing !

great thanks! it's working!

but it's little bit too late though =) i already gave up on a backup (not that big a deal though since now that i have done all the modifications i know what and how, shouldn't take me too much time to do everything again from a fresh install) and did a format from the power+ok menu. but that didn't give me back the ability to enter the maintance menu . just a moment ago i thought the zaurus might not be responding to the keyboard anymore, but pressing a+b+reset worked like a charm, so that's not it. i still need to get back into the maintance menu to restore the US nand backup to the zaurus. do they have a secret key combo for that too? a+r+reset?

Hi,

great thanks! it's working!
...do they have a secret key combo for that too?...

no, not as far as we know.
But you should be able to enter the diag menu. If the normal
ways don't work for you, try "FN"+"D"+"P" and tick the reset.
This should bring up the backup-copy of the service menu.
