How can I uninstall jailbreak on Kindle 3

[r1sh]

Good day, specialist!

I've got a problem with Amazon Kindle 3 and looking for help...

I've bought it in RUssia with Jailbreak 0.6N and Localization 0.4 installed.

I decided to uninstall localization and jailbreak, and I've tried many ways: unistalling jailbreak with jailbreak_0.6n_uninstall with jailbreak_0.10n_uninstall - no sence of hope
uninstalling localization with version 0.10 but file .update_loc_ru_0.4_install in the root of Kindle has just changed it's name to .update_loc_ru_0.10_install and Russian language has dissapeared from interface.
I've tried to install jailbreak 0.9n, 0.10n - nothing happened
I've tried to install localization - the same thing.

Can anyone help me uninstalling or updating all this stuff? Can I somehow format Kindle?

I've got firmware 3.3 and when i'm trying to install or update jailbreak using file update_jailbreak_0.9.N_k3gb-3.2.1_install for example, during Update I recieve error...

What is folder "src" in jailbreak archive for?

Why there are files in the root of Kindle?

That one I can answer:
It is just for reference by humans, not required for execution.

Your other two questions I have to leave for someone else to answer.
