Device(s): Hermes

After I run Step 9: the screen told me the ROM upgrade had completed successfully. But my Hermes screen is blank and it won't turn on anymore.
I tried to hold "power" and side "ok" button and hit soft reset and nothing happend. Then I took battery out and plug in USB cable and I only get red LED on top next to the Internet Explorer button. When I put battery back in the Red LED doesn't turn back to amber (the normal charging light), but I try the buttons to get it to bootloader again but nothing happens.

Any suggestion?

Thanks

Hello Paul,

Thank you for sharing your knowledge, I am still a beginner but learning as I go and plan to take couple of risks with caution. I hope you can give me feedback on the following please I really need it.

I have a HP iPAQ 612c it has WM6. My main goal is really simple but maybe dangerous.

1- backup pda images
2- restore pda images <--- dangerous

using the latest pdocread and pdocread itsutilsbin-20080731-2.zip from http://www.xs4all.nl/~itsme/projects/xda/tools.html

CODE

CODE

The follwing 2 methods is what I used to back up the 3 parts, both methods produced exactly the same file lengths, I am not sure if one method is more accurate than the other, can you please
if there is any difference between the 2 methods?

Method 1
pdocread -w -d TrueFFS -b 0x800 -p Part00 0 0x14fc00 Part00.raw
pdocread -w -d TrueFFS -b 0x800 -p Part01 0 0x1e0000 Part01.raw
pdocread -w -d TrueFFS -b 0x800 -p Part02 0 0x4cbc000 Part02.raw

Method 2
pdocread -w -d TrueFFS -p Part00 0 0x14fc00 Part00.raw
pdocread -w -d TrueFFS -p Part01 0 0x1e0000 Part01.raw
pdocread -w -d TrueFFS -p Part02 0 0x4cbc000 Part02.raw

I have also learnt that I should backup this file diskimage_Ver.nb0, I am not sure what is the difference between the diskimage_Ver.nb0 and Part02.raw but to show the correct address I typed
pdocread -t

To back up I type
pdocread 0x0 0x5000000 diskimage_Ver.nb0

Here is the most important question of all and one that I've been searching for an answer for, for at least 3 weeks now.

I would like to learn how I can safely write the image I created back to the PDA please

so here is what I learnt from one of your posts and I wanted to confirm with you if the following line seems to be correct?

I changed from FLASHDR to TRUEFFS and also changed the address to map to Part02.raw

CODE

can you confirm if this is correct?

pdocwrite -w -d TRUEFFS -p Part02 0 0x4cbc000 Part02.raw

I am not sure how I can write back the diskimage_Ver.nb0 file using pdocwrite?

What are the correct arguments?

pdocwrite 0x0 0x5000000 diskimage_Ver.nb0

Thanking you in advance and I'd really apprecaite any feedback.

Thanks

I tried this line and it is incorrect

CODE

pdocwrite -w -d TRUEFFS -p Part02 0 0x4cbc000 Part02.raw

it will produce the following error:

CODE

C:\tools>pdocwrite -w -d TRUEFFS -p Part02 0 0x4cbc000 Part02.raw
CopyFileToTFFS(0:0, 4cbc000, 00000000)
ERROR: Unable to open host/destination file - The system cannot find the file specified.

but then I tried the following which seems to be a little more accurate but also produced an error:-

CODE

pdocwrite part02.raw -w -d TRUEFFS -p Part02 0 0x4cbc000

The error is :-

CODE

C:\tools>pdocwrite part02.raw -w -d TRUEFFS -p Part02 0 0x4cbc000
CopyFileToTFFS(part02.raw:0, 0, 04cbc000)
ERROR: ITWriteDisk - The media is write protected.

any ideas?

thanks
