Hacking about to hack my wii-u and i have a few questions

[butfluffy]

first off, sorry if any of these questions have been asked before but i have been searching the forum and can't find any answers so i decided it's best to ask. i'm on 5.5.2 and i'm going to buy a DS VC game and install Haxchi but not cold boot because it sounds a little more risky.

1. the hack guide states that if everything goes well then then games purchased on the Wii-u and NNID will remain intact after the hack. has anyone lost the NNID and purchased games after the hack despite following the guide exactly?
the reason i ask is because i have quite a lot of games which are missing from the title keys site and would like to keep my NNID and games so i can dump my tickets and add to the title keys site for the scene.

2. i know that if you connect a wii u external storage device to another wii u system it will need to be formated but is this the case when running CFW?
the reason i ask is a have a mate who will not hack his wii-u but he has some eshop games that i don't have and they are also missing from the title keys site.
i was hoping that cfw might let me insert his external usb device into my cfw wii-u and dump the tickets which leads me to another question.

3. so the other question... when dumping tickets are the tickets located where the eshop game is installed (IE: usb storage) or are they always located in system internal storage or system nand?
if the tickets live in internal storage or system nand then dumping tickets from someone external usb device would not be possible anyway.

4. the last question... i know that the wii-u eshop is region locked just like the 3ds but with cfw can you change the wii-u region and access another region eshop? i know this is possible with a 3ds after region changing the system but it my 3ds would still not allow my to access another region eshop afterwards for some reason.
has anyone done this on a wii-u with success or is it just not possible?

any hep would be great guys and sorry again for all the noob questions.

1. you won't lose your games. I own 76 digital games for the system, all intact.

2. still can't do this.

3. you can backup tickets with tik2sd. they'll appear on your sd card.

4. I don't think this is possible. you can make the system sorta region free, but accessing another eshop, I'm not sure.

thanks for the reply. pretty much what i expected but nice to have confirmation.
i was going to use tik2sd tool to backup my tickets but my mate wont hack his console. he only has an handful of missing games and i can purchase those from the eshop and backup the tickets later i guess.
i'm trying to get as many games preserved as possible before nintendo get around to removing them from the eshop for good. doubt that will happen anytime soon though.

He doesn't need to hack his console just follow the step 2 browserhax guide to load Homebrew Launcher with tik2sd on his SD card: https://gbatemp.net/threads/guide-community-noob-guide-to-wii-u-hacking.451297/

doubt i could convince the guy to even do that temporary browserhax in order to dump his tik's. he's so paranoid it's not real.
