Help with modding and hacking the ipod nano 7th gen?

[n1kn4k]

Hi people, i have got so far as to opening up the ipsw file and have got three files:
N31.bootloader.rb3 -146kb
manifest.plist - 579 bytes
Firmware.MSE - 166mb

Obviously, most of the operating system is in firmware.mse, but all i have been able to open is manifest.plist which says this:
[If you are using the URL embedded in the script, take out the brackets and spaces - new members aren't allowed to post urls]

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "h()ttp: / / )w(w) w . apple(.)com /DTDs/ PropertyList-1.0(.)dtd">
<plist version="1.0">
<dict>
<key>FirmwarePayload</key>
<dict>
<key>BootloaderName</key>
<string>N31.bootloader.rb3</string>
<key>BuildVersion</key>
<string>37A10002</string>
<key>FamilyID</key>
<integer>18</integer>
<key>FirmwareName</key>
<string>Firmware.MSE</string>
<key>ProductVersion</key>
<string>1.0.1</string>
<key>UpdaterFamilyID</key>
<integer>37</integer>
</dict>
</dict>
</plist>

I guess i could use this if i had build my own firmware.mse, but i have found no way of unpacking an .mse file.

Also, does anybody know how to get the firmware directly off of the device?

Hi n1kn4k ! It's easy to unpack the firmware.MSE

1 - Download extract2g, extract it and build it with the command "make" in your terminal window.

2 - Take your firmware.MSE and drop it in the extract2g folder.

3 - Now, in the terminal, use the "cd" command to go to the folder "extract2g"

4 - In the terminal, copy and past this command : extract2g -A Firmware.MSE

5 - This will now dump the firmware files in 9 .fw files :

• appl.fw
• bdhw.fw
• bdsw.fw
• chrg.fw
• diag.fw
• disk.fw
• lbat.fw
• osos.fw
• rsrc.fw

6 - Now, you have to convert them into .img files, so in the terminal use the command : dd if=rsrc.fw of=rsrc.img iseek=2 count=321546 and you'll have your .img files Now you can explore it

/!\ the last command (dd......) only works in unix based OS, so in mac and linux, it works, but not in windows... /!\

how much of this will work on windows, and how can I do this on ubuntu (if i can't on windows)? I don't have a mac

If you don't know how to do it now, seriously, it's better for you to stop now !
But if you don't, so install ubuntu and run your terminal (search "terminal") and paste all the commands i gave =)

Hey n1kn4k I just posted the extracted firmware on my thread, but before you try to do anything with that I want you to get some experience and extract the MSE file. PM me once you've done this then you can help me with my hack. You've got some homework to do.

[n1kn4k]

Yes, thanks Nevera11ling - I have extracted the firmware and ended up with a load of fw files. Now, I have a quite old 1gb ram 40gb hard drive pc with ubuntu on, it, and am trying to get that to work so i can convert them into imgs

[n1kn4k]

I don't mean to be a massive ubuntu n00b or anything, but it's not working on ubuntu:


*************:~$ cd /media/USB-8GB/Projects/Ipod/Extract2g
*************:/media/USB-8GB/Projects/Ipod/Extract2g$ extract2g -A Firmware.MSE
extract2g: command not found
*************:/media/USB-8GB/Projects/Ipod/Extract2g$ dd if=rsrc.fw of=rsrc.img iseek=2 count=321546
dd: unrecognised operand `iseek=2'

[n1kn4k]

Haha guys dont worry just a typo

[Neverfa11ing]

Haha typos suck when you try to run commands. Just an fyi you can convert all of those fw files to img files. I would do that so you can experiment with those files. Look at my post on my thread to see how to unpack those img files.

EDIT: Could someone close this thread because it's mainly just a repeat of my thread so now I have to give a response to n1kn4k on two threads. Btw good job on this stuff n1kn4k but lets keep the information all consolidated in one place.

[n1kn4k]

Yes ok - how do i close a thread?

[Neverfa11ing]

I think you need a moderator to do that.
