Sharp JP ROM: Upgrade C760 to C860

[HennaOjisan]

Thought I share just in case there is someone interested.

I just completed upgrading my C760 JP to C860 JP spec. I couldn\'t think of any reason why it wouldn\'t work. It works and while the Translator is a huge file (50MB), it has far better vocabulary than the standard dictionary so I found it worth while. Of course USB storage is nice. Now I gotta decide which way to converge, X11 or Sharp JP.  

Steps I took was:
1) Get ROM image from http://downloads.conics.net/pda/zaurus-sl-.../service-menus/

2) Rename the file from SYSTC860.DBK to SYSTC760.DBK

3) Flash

4) This image contains the translator dictionary in the user area, so if you \"Erase All\", you will lose the dictionary. I use SD card to hold/organize some apps and data. Transfer  \"/home/QtPalmtop/translator\" to CF/SD card. That\'s the 50MB dictionary you want to keep.

5) Goto ~zaurus/Setting/ and edit \"translator.conf\" and \"translator_ej.conf\" with appropriate paths.

6) Make sure everything works at this point. Backup if necessary. Then, \"Erase all\" to refresh.

7) Now you can rebuild your Z with the new Translator and USB storage.

Note: You can\'t \"Restore\" from the old C760 data, but I suspect if you took the time to edit the backup list files, you could probably do it. I simply rebuit it and transfered the PIM data etc manually.

When you \"Backup\" now, it will back it up as C860. The service menu will change to C860 as well.  No problems so far for me, but do it at your own risk  :wink:

If you want to restore from the old backup then change the backup name from 2003-12-03-22-24.backup_SLC760-JP-1 to 2003-12-03-22-24.backup_SLC860-JP-1, you will also need the C860 version of updater.sh if you want to flash a new rom or kernel as the machine thinks it is a C860.

Thanks, didn\'t try that... I was refering to the Backup to the PC (using bundled Sharp software) where it generates files, \"devs\" \"lslr\" \"machine\". And a quick try revealed that it checks for little more than the model name... For example, the machine ID were very different for 760 and 860. Backup to SD/CF is probably the way to go if that works.

Ahh, never done a backup to PC cause the bundled software is for windows  , just backup to SD/CF and then scp it across to my Gentoo box when I get home.

By the way have you noticed that your /dev/rtc is no longer available after you installed the C860 NAND on the C760? It used to work (I think) but after flashing the C860 NAND hwclock reports /dev/rtc as busy and doesn\'t show time. No big problem cause the Z keeps correct time.

The translatino software rocks - makes surfing Jaapnese Zaurus sites that much easier on the Z.
