What about samsung e60

[quedificil]

It's very easy to change the default ebookstore webpage to www.google.com.

Just change the name of the default webpage in the QT main file to the new one, for example www.google.com.

Repack the firmware following the instructions in the readme file and install it. It works for the E60 and the E65.

It's also posible to activate the email client for the E60 / E65 changing the parameter config in the QT compiled application.

Changing this parameters and the default webpage is ilegal cuz not are part of the firmware GPL licensed files.

Is it possible to unpack a firmware update, or do we have to get the source code first? I'm on a slow internet connection and would rather only have to download the smallest file of the two, which is the update.

Yes, it's possible to unpack de firmware update with the pbarette utility (link posted in this forum) , but you also need to repack the firmware after modify the main QT compiled file, and for that you need the repack utility that are only in the source code package from samsung developer's site.

Aww. 5 hours of download to go, then.

Thanks for the lead!

Hello Quedificil,

Could you be more specific ?
which files should be modified ?

[Papi]

Yes, it would be nice if you could describe the procedure. Actually what's I've reach so far is :
- decrypt the official firmware with pbarette's utility : just drag & drop the bin file on the dialog box.
- this produces 2 files if I remember correctly, one is named something.squashfs, you can "decompress" this one with unsquashfs.exe (I'm on Windows to do that, but I guess it would not be very wise to rebuild the firmware on Windows)
- under I don't remember which directory, there's a MainApp file (binary), if you edit it you can see the carrefour store url for example and replace it.

Now I guess it would be more interesting to disassemble MainApp, this would allow more significant changes and recompile it. pbarette I think mentioned it disassembles pretty well in IDA, but this software costs something like 500 €.

Another thing is I'm not sure how to rebuild the package, I see there's a mkpackage utility, and a shell script calling it, but...that's it ? Which readme file gives the packaging instructions ?

[silver84]

Yes this reader dont find WIFI if it has hidden SSID.
Perhaps something can be modified in a .conf file; it would be nice to get root connect...

For modified firmware, it would be nice also if we can download it

Correct, you only need to modify the MainApp file, changing the actual URL default text for another url (www.google.com), you can find the file in /usr/local/Trolltech/QT......./bin

After doing that, u need to squash the files, and call the script that executes the mkpackage.

(Pack the squashfs-rootfs folder into the rootfs.bin)

The IDA don't support the Samsung S5PC110 Cortex A8 ARM processor.

it seems that it is not possible to define any configuration NOR to modify one !!
besides, it seems also that the E60 does not like access points that are not secured ...
has anyone been able to find a bypass ?
my own project is to be able to come up with a setup using my 3G mobile phone as a wifi access point for the E60: joikuspot for instance used in the phone

As far as i can see, MainApp is a binary file. How do you modifiy the URL ? With a hex editor ?
You spoke also a mail client (i have found the icon in the squashfs file). How do you activate it ?

[Miles Prower]

Hex Editor yeah.

I used Bless and/or ghex2, and found the bookstore URL*at offset 0x10F8EF4 in /usr/local/Trolltech/QtEmbedded-4.5.1-arm/bin/MainApp - I guess it's indeed not too hard to change it.

Tried to compile the vanilla sources to no avail. Is there something specific to do?

make-60FR.sh (and mkpackage) reports no errors:

The reader sees this update fine, once its magic number changed, and agrees to install it (version is 1006.*However, on reboot, I'm still on the regular 1002 firmware with no changes whatsoever.*Any clue?

You don't need to compile anything is your only change is the MainApp, just repack with the squash utility and run the ./make-E60FR.sh

[Miles Prower]

Well, erm, yay.*By "compiling" I actually meant "running make-E60FR.sh" in that way.

[Deeheff]

Can someone please post a link for the repacked firmware for those who don't know how to play with linux command code? in advance!
