How to change carrier (e.g. DOCOMO => SOFTBANK) with out rebooting WP76xx?

you can downgrade to R12 and then use swiflash recovery mode.

Wp76 root password

First of all, the command should be “swiflash -m wp76xx -r” instead of “swiflash -m WP76xx -r”. Next, I found that it is not working on R13. But in case you first downgrade to R12, it works!
