Hacking Softmoding Wii 4.2E after updating

[tamiron]

To begin with: I'm a total noobie when it comes to Wii Hacking - please understand if I'm saying bullshit.

I have a softmodded Wii 4.2E - I have a HBC and I play games from an external HDD with a USB loader.

I want to:
1) upgrade my Wii system to the latest Wii version of my region (4.3E). I understand that after I do this my Softmodding is lost and I have to hack the wii all over again. (Is it true?)
2) Softmode the Wii and get HBC again
3) Install a working USB loader.

I have all the things needed to softmode:
-Wifi
-SD card
-external HDD

How do I do any of these things so it works? There are many old links when I search google so I don't know what actually works.
Thanks!
