I.E. Someone who hates the ads can swap serial numbers with someone who wants the ads. Maybe even exchange some money in the process..

You sure can, but I don't know if anything bad will result. If Amazon ever releases 3.2.1 update for old Kindle 3.1s, I would try that with someone.

Well as i said i'm new to Kindle hacking but considering this is the same hardware we're talking about , it should theoretically be possible to flash a clean (ad-free) firmware image and vice-versa ?

PS : If you wish to try out the ad exchange thing , please let me know

[gecko11]

me too please!!! i want to get rid of ads! i didn't know that is the sponsored version. and when i registered it, it was too late to get my money back. the ideea to pay for an non-ads upgrade is very good. i would pay for this.

yifanlu, If you wish, we can try to exchange with serials, but temporarily (I must have KSO to check my localization hacks on it). Maybe we also must exchange Kindle Hardware ID if Amazon track it too...

UPDATE:
I'm tried to change SN and... got not working Wi-Fi module... I don't know what is wrong, but after changing SN, settings page says "Wi-Fi MAC Address: Unavailable" and Wi-fi can't connect. Changing SN back enables Wi-Fi
So, please do not change SN or other hardware ids if you not have Serial line adapter to repair it.

There must be a firmware setting that enables ads. It cannot be server-side because my kindle was reset remotely, something HAD to have told my kindle to stop displaying ads. This changed after a factory reset. What if I wasn't able to connect to WiFi and Amazon had to tick that setting? There is a firmware value.

[Sir Alex]

dasmoover, This setting is Amazonas side. It can mark you Kindle as Special Offers device or not.
Factory reset removes any ads and you got usual Kindle.. until you connect to Amazon. It verify thath you Kindle KSO or not and Send or not send the ads to Kindle side (All operation done via TODO list) So, when you call him, he removed your Kindle from AD enabled devices, and after factory reset you Kindle stay as usual Kindle.

Even if you change your mac-secret etc it won't work..
(tried cloning two devices, so cloned ALL the values!)
Only thing I didn't try is to copy the display Eeprom.

FYI: Other stuff to know:

##manufactoringcode ends with:
echo -n "mac-address" | md5sum |cut -b 29- | cut -c 1-4)

PCB serial:
end with "SHW" wifi only
end with SHR wan/wifi

machineID is stored in: var/lib/dbus

Yifanlu, I have tried over 20 times to get this JB working, I even wrote a small bash script to cp the file over as soon as it mounts. I end up with error code ranging from U002, U003, U007


ERR_GENERAL=U000
ERR_BUNDLE_VER=U001
ERR_BUNDLE_MD5=U002
ERR_IMAGE_MD5=U003
ERR_UPDATE_MISSING=U004
ERR_UPDATE_TMPDIR=U005
ERR_UPDATE_FAILED=U006
ERR_SIGNATURE_FAILED=U007

I have tried a factory reset as well.

Version: Kindle 3.2.1 (576290015)
Any help would be appreciated, thank you.

I have successfully changed my KSO to non ADS Kindle
Steps:
1. You must change SN, Board ID, MAC, Manufacturer Code to values from non ADS Kindle
2. Reset to factory defaults (it will remove ads and resets hardware info cache)
3. That's all

Have you tried just one (sn, board id, mac, manufactur code) instead of ALL of them for each?

[Sir Alex]

yifanlu, no, simply change all codes

Did you try just the serial? Did it not work?
