update_reginfo_v0.2a has been worked successfully with me on old firmware (ver 2.1.1) of Kindle DX (B004).
I think manual coping of this XML file called
reginfo:
PHP Code:
<?xml version="1.0" encoding="UTF-8"?>
<response>
<user_device_name> My kindle </user_device_name>
<global_device_name> name@mail.com </global_device_name>
<given_name> My Kindle DX </given_name>
<name>My Books</name>
<alias>name@mail.com</alias>
</response>
To:
/var/local/java/prefs/reginfo
(after
mntroot rw command) will be enough.

But it needs USBNetwork hack with some command-line experience.
