I was screwing around with the flash memory, and bricked my Z so hard that it wouldn't do anything except flash the mail and power LEDs. None of the special boot sequences I know worked and I couldn't get to the NAND restore, or any other restore procedures I knew of.
I looked around for solutions in vain, and I was getting to box it up and start the long round-trip to Japan, when a lucky set of Google search terms came up with an idea. I tried it, and it worked.
Since the page I found is only in Google's cache of the dead externe.net forums, I'm going to copy it here for posterity.

I have the solution!!! I am so happy now!!! I was surfing for hours and hours, and playing with binary files and dd...
But I found a website that has the solution for my device: http://www.piro.hopto.org/~piro/pukiwiki/p...B%5BP2ROM%5D%5D
I pushed FN+D+M while connecting the AC power, and suddenly I did have a Service Menu!
Now I'm trying to restore a c860 NAND from www.trisoft.de.
I'm also going to copy a translation of the Japanese WiKi page. It seems to have a very complete description of special ways of booting.
Because it was possible to revive with NAND RESTORE here when FLASH in zaurus has been crushed before, let's write the thing that it did around here or the doubt and.
It is a thing of the reference as for the page above. Moreover, I will read the page of 59414D41 Mr. to whom the page was written.
It is considerably important and comprehensible.
By the way, the thing done after it determines it of act of danger considerably. The responsibility cannot be taken no matter what it happens.
It had already been destroyed, and this act was able to be eased for me.
By the way, only SL-C700 is confirmed.
How for start-up of debugging menu.
Basically, it stands up by turning on the lock switch of the battery lid while pushing some keys.
Moreover, it is acceptable even if it pushes at the restart. The battery is removed, and it is OK to do the adaptor in while pushing the key.
From Zaurus forum
key combination boot option number action Operation by my Zaurus
none 0 normal boot Usual boot
? 1 BOOT REMOTE DIAG ?
DP 2 Normal diag Refer to the page of 59414D41 Mr..
DM 3 Service diag Refer to the page of 59414D41 Mr..
DC 4 Update NAND from NOR There is no CF update screen.
QT 4 Update NAND from NOR There is no CF update screen.
DL 5 Boot CMDLINE is changed and it boots it. Usual boot
DZ 6 Update NOR from NOR For Flash combustion of Bets without NOR update screen(Maybe,)
DK 7 Update NAND from NAND There is no CF update screen.
DB 8 BOOT: Maintain kernel Guy of boot 0x220000 of kernel for maintenance
AB 9 Backup backup ?
DV 9 Backup backup ?
DA ? Angel Debug Monitor Angel Debug Monitor version 0.42
DR ? REMOTE CHECK It is output with REMOTE CHECK 2400bps. The command of two characters can be sent. Is it considerably danger or .. Bootflag can have changed.
LX ? It is the same as option number 0. ?
Fn+P+D ? Normal diag Diag is booted without NAND LOADER's passing. (In the cereal output,)
Fn+D+M ? Service diag Diag is booted without NAND LOADER's passing. (In the cereal output,)
Oh dear the around here person ..NAND FLASH BACKUP.. thinks with diag menu.
C750 ..kernel.. is seen and doubtful reset_key_combination ..corgi_logkey.c.. is discovered.
Fn+Home, Fn+P+D, and Fn+M+D are recorded anything doesn't happen though it tentatively confirmed not recording up.
Can only SL-C750/760 be done because it is not in the kernel of SL-C700?

/(mtdblock2) was not able to be read for a moment suddenly ..the former kernel and...
Oh dear, it is generated the error while writing it when thinking the furnace as soon as reconciling when initrd.bin is rewritten.
At this point, the debugging menu ..information.. worries .... considerably. Including thing sent to repair
And the net are variously examined and the cod and the debugging menu are discovered to be. (..piling up.. did not only read ..ｰ.. neatly. )
When it boots with DB by the kernel for debugging, and mtd2 was done in the mount, writing is improper though it is possible to read somewhat for the time being.
NAND is backed up with diag menu though it is first of all broken in the said thing. Can it become calm a little because it considerably drives it at time the other day?
Error generation in restore though it manages to obtain SYST700.DBK, and restore is done. At this point, it considerably becomes blue.
The thing that restore can be done confirms the backup goods of NAND of broken, and NAND FLASH(FULL) is executed for the time being. The resignation mode around here considerably.
Restore can have been done by doing SYST700.DBK ..obtaining.. in restore. It is a considerable state of the excitement here.
It was possible to finally revive.
Thank you for information about 59414D41 Mr..
Choi at about half a day at this period.
However, restoration was very because my system had been completely customized.
When a considerably steady system can be done, one degree NAND FLASH BACKUP.
However, it is ..painful.. to take time to back up. For about one hour(With SD. )
It has understood well and a postscript is added when fiddling with this while ..the.. output.. seeing making the cereal cable somehow. The cereal cable was connected directly troublesomely though had when seriously making it by using MAX3222 first.
The thing that tentatively entered boot and the maintenance mode can have been done though MAINTE and DIAG of C750 were incidentally put in C700. However, it seems writing in P2ROM and a furnace around here with SL-C700 on the screen of the maintenance mode because it goes out.
Even if reset hanging when the battery lock locks also replaces MAINTE, it is put on P2ROM, and it is hardware or might be either. a kooky bowl Because the advantage doesn't exist maybe even if MAINTE of C750 is put, either it is not worth putting it.
