C760 Won't Stay Unbricked

[gr8ful]

My C760 froze up and would not power off.  I removed and re-installed the battery and got the flashing mail light.  D+M Service menu 'Reset' did not fix it.  After multiple attempts, I was able to follow the instructions for unbricking in several threads and successfully did a NAND Flash full erase and a NAND Restore.  

When attempting to flash Cacko 1.23 I was able to resize the root partition to 32 but when I tried to repeat the steps to flash the rom the flash menu would not come up.  After leaving the battery out for over 15 minutes I was able to flash Cacko 1.23.

My Z locked up again before I was able to load any ipks and I am back to the flashing mail light again.

Anyone have any thing else I can try?  Anything in the service menus that might tell me what the problem could be?

Suggest that you try increasing the size of the root partition to 34 as 32 is the minimum & assumes you don't have any bad blocks.

This worked on my C760.

my root is 35Mb, seemed to help with inode errors

Well looks like it is a lost cause.  I can get to the D+M service menus but anything to do with the NAND (NAND Bad Count, NAND Flash Write, NAND Flash Read, NAND Write&Read Rpt, & NAND Flash Full Erase) I get the following error: "ERROR! cannot initial. code=(-2)".  I guess this means that my NAND chip is unrecoverable.

If anyone has any other recovery tips I'm all ears, otherwise I've got a spare parts machine.

I vowed the next Zaurus I bought would have integrated wifi and possibly bluetooth. I'm not so sure Sharp will put out such a device so I'm looking at either a C1000 or C3200.  I already have a 4gb CF card so the C1000 makes more sense, especially if there are usb wifi adapters that work with it.      

Thanks everyone for your help.

I have an 860 with a craked display. perhaps we could work somthing out.

I'm currently looking to sell to someone who PM'd me, but if that doesn't work out I'll post to this thread and let anyone interested know I have a parts donor machine.


Thanks

If you guys don't work something out, I also have a bricked device that I'd be willing to try to work something out over. (My screen is fine but my NAND is hopelessly failing.)

Sold my C760 to be an organ donor.  Thanks to all who offered tips and advice.  I believe my NAND was bad, so not much one can do about that.

Now what do I do?  C1000? C3200? Jump ship and look to get a different handheld?  The Zaurus is by far the most versatile handheld available.  I may possibly wait till the end of the year and see what pops up on the horizon. Will Sharp come out with the dream Zaurus with integrated wifi & bluetooth?  Will Apple surprise everyone with a video iPod with pda functionality?  I also remember reading that after Psion sold their stake in Symbian, they were looking to develop a Linux based handheld.

Knowing my impatience, I will probably order a new Zaurus before the week is out.


Peace out
