kindle dx custom sim

http://www.mobileread.com/forums/archive/index.php/t-60006.html

Hi. Today I decided to lose my warrant and opened my DXi.

Changed SIM card to a Claro-3G (Brazil).
After some trying, mounted --bind the /etc/ppp and successfully made a PPP connection.

It's pinging any valid host.
Also mounted /opt/amazon/ebook/config to change the proxy settings.

Now I got web-browsing.
It also downloads amazon converted files from [email protected] the same way. And still charging 99 cents per mb.

The reason i'm doing this is because amazon don't even offer a paid option to use web browser in my country.

You must have shell access to the kindle to preform these steps.
You should also backup all files before you edit them!

1.) Open your Kindle and switch with your own SIM card.
2.) Open '/etc/ppp/chatscripts/att-connect' with your favorite text editor.
3.) Edit the amazon APN to your service providers APN
4.) Save and Close
5.) Move the symbolic link '/etc/resolv.conf' to '/etc/resolv.conf.bk'
6.) Copy '/var/run/resolv.conf' to '/etc/resolv.conf'
7.) Open '/etc/resolv.conf' and replace the nameserver IPs with those from your service providers.
8.) Save and Close
9.) Open '/opt/amazon/ebook/config/browser_prefs'
10.) Place a # in from of the three proxy lines.
11.) Save and Close
12.) Restart your kindle.

Im sorry theres not more detail as I am currently at work and am repeating from memory as I do not have access to my Kindle. In about 10 hours I will post more elaborate directions.

@ Timestorm: Good work!:D

I additionally removed the Startup-Sequence "S50wan" at /etc/rc5.d because I killed a SIM-Card - after a time it stopped working and had to be replaced.
I guess the reason could be that S50wan (resp. /etc/init.d/wan) starts and stops the modem - maybe the SIM was killed by often switching on and off.
Also this removed the modem-update sequence as the firmware of the modem is up to date and no need for further updates this time for me.

Additional removed S50updater at runlevel 3 (/etc/rc3.d) - because at this time I made a lot of modifications to the filesystem and updates would fail anyway.
Why?
Updates check the md5-hash and there is a very good reason for this: Not because of secrets or similar - no - the solution is that updates are made mostly by patching. An if you would patch modified files they could become unusable...

At least today I mounted a plug at the top of the kindle to easily access the serial-port for debugging purposes ;-)

Well as far as good - have fun!

Best regards Josh:cool:

I succeeded changing amazon's SIM card in my kindle dx graphite to my local GSM provider's sim and getting online :)

this is what I did:
1. changed sim card in kindle
2. commented these lines in /opt/amazon/ebook/config/browser_prefs
#settings.proxy.hostname = fints-g7g.amazon.com
#settings.proxy.portnumber = 80
#settings.proxy.sslportnumber = 80
btw, if you don't want your kindle to be recognized online as mobile device, change browser identification string in the same file to smt like this:
user_agent.base = Mozilla/4.0 (compatible; Linux 2.6.22)
3. changed DNS server's ip addresses to my GSM provider's in /etc/resolv.d/resolf.conf.3
4. changed some settings in /etc/ppp/chat/connect-3 to be compagtible with my GSM provider's settings (dialing number and AT+CGDCONT connection string)
5. rebooted kindle and thats it! internet worked :)
