PRS-600 Has anybody looked at Russian hack of PRS-600?

Cygwin uses Linux style of directory listings. So your c:\ becomes /cygdrive/c/ and so on.

However as porkupan has said — just following some directions blindly without understanding what you're doing is a very dangerous path to take and can very easily produce a very expensive doorstop...

thanks very much for advices,

i know it is dangerous but i need this reader to read texts in my language,i dont know why a reader with Sony barnd just supports english.even chinese models have better support.if i cant read the books of my language it is not good for me.reading just PDF in a 5 inch screen is not possible.


i did changes at command.i writed this command:

cramfsck -x /cygdrive/c/opt /cygdrive/c/new_opt.300.img

it made the folder opt at drive c but it is empty and also an error message:
utime failed: /cygdrive/c/opt/: invalid argument
th picture:


may be i should forget making changes.and even reading on this device.

[porkupan]

You should play in the local directory:

cramfsck -x ./opt /cygdrive/c/new_opt.300.img

thanks very much porkupan and dmapr,

i tried your new command code:

cramfsck -x ./opt /cygdrive/c/new_opt.300.img

but again the same error: invalid argument
picture:


thanks so much.but as you said i am not expert and i cant extract this file.better to forget it.i wont use my reader.

sorry for the questions and thanks for the time.

you should enter the folder of cramfsck ,and where is cramfsck.exe?
but i cannot unpack the IMG ,too

[porkupan]

Looks like you don't have write privileges in this directory where you are trying to unpack new_opt.300.img. This is some wickedness of newer versions on Cygwin, they started messing with permissions, and they don't do it right somehow.

Just remove the opt directory, and change permissions for the local dir:
chmod a+rw .

Then it should unpack.

dear Porkuoan,

i removed the opt directory ,then i used your command:

chmod a+rw .

then i used the cramfsck command:

cramfsck -x ./opt /cygdrive/c/new_opt.300.img

it made the opt directory again but i got the error again.
utime faild ./opt: Invalid argument

!!!
is it my wrong action or something else?

[porkupan]

Well, don't know, it works for me. Try a real Linux system, maybe you will have better luck there.

I'll second the suggestion. Check out http://www.pendrivelinux.com for an easy way to set yourself up with Linux — assuming your computer supports booting from USB devices, which almost all of the modern ones do.

I have the clock ,left the reader on last night and noticed that it had consumed a large amount of battery power,presumably due to clock up dating.

Once again I suggest you make sure you are not using am/pm-tick or 24-tick option of the clock, but the regular am/pm or 24. The "tick" clock doesn't let the reader sleep between page turns, so it eats up the battery quite quickly.

Many thanks got it sorted

What is supposed to happen at your step 10?

I'm running the boroda firmware 1.05d. On an SD card I've done the following:
1) created test
2) in test I put everything from the test-flash and test-autorun
3) created /Sony Reader/software/autorun.xml
4) turned on the reader, waited until it got to the home screen
5) press home and vol+ buttons together
6) while still pressing, insert SD card
7) testing menu shows up, I release vol+ and home
8) I press the zoom button (the one with the little looking glass with a + in it)

Result? next to "1 of 2" a circle with a line across it appears, like a "no entry sign": http://www.michaelis.uct.ac.za/images/no_entry.gif

Nothing else happens. Am I missing something?

7) replace new_opt.600.img and new_opt.600.md5 in "test" with the modified image and md5 files.

8) in SD card make an empty file "Sony Reader/software/autorun.xml"

9) hold MENU button and Vol + at the same time, then insert SD card till the testing menu shows up. release buttons.

10) press "ZOOM" button to load test FW. If successfull, the new image files are good. You can do the regular flash. For me, the image file is too big since the chinese fonts files I added are too big. This is the reason to be safe.

Just a tip: VirtualBox (from Sun Microsystems) is free and quite lightweight.
