D 750 debrand , guide needed

[MadMax71]

Now I remember, it was Wotan client over a year ago who did this for free, but now you need a credit for that I think. Maybe give it a try.
1. flash red erom with: safest way Wotan client, for free but risky XS++, if erom area gets destroyed you can still repair it with a service cabel like Cruiser Xin1 or Fightercable
2. yes
3. no need for that just leave it as a CID36
4. yes, be aware the firmware is red and CID36.

Good luck!
