I killed my Zaurus C860 HELP

[Fire-Armor]

Help some please...

I somehow killed my Zaurus C860 and now I can't get to the D-M screen to do a  NAND restore...

The last thing I did was flashed with X11 Rom version 1.05 and it was working ok, but I couldn't get the wireless socket card to work so I decided to restore the ROM with the NAND backup I had got to the D-M menu and I was flicking through it with great speed as I was pressed for time, I must havd pressed the RESET option and now when I boot up all I get is a Black Screen.

I can still get too the OK-Power On menu screen the one with the 4 options but its useless.

I tried the D-C option but the lights on the Zaurus C860 just cheaps flashing on and off it does not stay on constant for me to use the recovery kit files. Plus the recovery kit files state the files may not work...

I really need help to unbricking my Zaurus C860 PLEASE

I was thinking also can one use a C760 recovery kit file to restore the c860 as it basically almost the same machine apart from the Japanese translation software and Samba stuff.

Anyway Someone Please HELP ME


Thanks

Leave the battery out for about 15 min then try FN+D+M

Has worked on my C860s sometimes when just D+M didn't want to "take".

Hi Miami_Bob,

But the steps advised did not work with my C860

I did find somewhere a link by another user for using different "Boot Key" start ups, and I downloaded this C860 Recovery Kit unzipped the files and did the following:

Boot Key location : http://www.piro.hopto.org/~piro/pukiwiki/p...B%5BP2ROM%5D%5D

1. copied the files to a CF

2. removed all power ( battery, AC )

3. left the unit for 15mins

4. held down these keys "D - K" powered up

5. the 2 lights started up and stayed lite for about 1 min and then powered off.

6. removed all power again

7. held down these keys "D - M" and I got the service menu.... Wooo Hooo

But now I have another problem damn I ran the "NAND Bad Count + Sum" and I now have "Bad Blocks" which I did not before I did this recovery.

Blk........Init........After........Total

OK!

I have these 2 Bad Blocks now? how do I get rid of them so that my C860 goes back too its original state?

I also did this to try and figure out what caused it.

Service Menu Screen 1 "NAND FLASH SUM" option

It is here I found out that the recovery kit files that I used have X incorrect (wrong versions) files in the kit. So even though it has brought my C860 back to life and granted me access too the Service Menu "D-M" I now have 5 incorrect files in my system which I do not know how to update or replace with the correct ones.

The files in question are:

"MAINTE: Ver. 1.20 --- Sum1 (4231) Sum2 (4233)"
"KERNEL1: Ver. 1.10 --- Sum1 (0460) Sum2 (3753)"
"ROFLSYS: Ver. 1.20 --- Sum1 (427b) Sum2 (aa0f)"
"PRESET: Ver. 1.20 --- Sum1 (6c5d) Sum2 (d0c0)"
"INFO: Ver. 1.10 --- Sum1 (4d74) Sum2 (4d7c)"

So these are the files that are incorrect and now causing me to have 2 Bad Blocks? so is there anyone out there that has a more up to date recovery kit with more up to date files to fix the incorrect ones ?

Anyway Thanks Miami_Bob for coming to the rescue and telling me what too do as I was feeling rather lonely thinking I KILLED me C860

Bad blocks are not caused by specific files existing on your flash, they mean that 2 blocks  of flash have gone bad - in other words, they won't work... Used to be very common on hard drives to have  acouple bad blocks but the system marks them as 'bad' and just doesn't use them, no big deal.  There *should* be a way to mark the bad blocks, and then re-flash...

Hi blakeyez

Oh I see, and thank you for the insight

But can you give me a few steps on how I can mark them or what I must do?

I have also now managed to track down a rather old NAND C860 version 1.10jp ROM and flashed it now I have only 1 bad file, with an incorrect sum

But I would still like to have the bad blocks marked so that I feel more relaxed, apart from that I am just happy that people have responded and given me some insight into my problem...


Thanks You Guys and Gals ( don't want to leave anyone out  )

I've never had to deal with bad blocks on my zaurus, so cannot offer any explicit instructions for how to mark them 'bad'.  Really, the nand bad block scanner in the D+M maintenance menu SHOULD do that for you... However, as I said, I've never dealt with them myself.

I know there are a few topics out there (perhaps in the ZUG faq?) about bad blocks and dealing with them, though.

So far I have never had to deal with bad NAND blocks and can't offer direct first hand advice. I agree with blakeyez that the bad blocks are not directly related to the "wrong" files on your system. The blocks going bad MAY have been the cause of your initial loss of access to the D+M menu (but this is just speculation).

Some other posts have reported Cxxx units that run normally while showing bad blocks, so it may be that ECC is automatically correcting for them despite also reporting them.

Can you still get to the OK-PowerOn menu? If so, I would try downloading a copy of the Sharp v1.40 install set and seeing if the ROM will install from the OK-Power menu. Then recheck the blocks & files.

BTW - did you change partition sizes at some point? If so, you might also want to use the Cacko loader to reset them, just for grins.
