Install and root KitKat or Jelly Bean Stock ROMs + TWRP 2.8.2a on a Wiko Rainbow

I recently got myself a WiKo Rainbow and ofc wanted it to be up to date. Unfortunatly Lollipop 5.x for the Wiko Rainbow is not in sight for now. The most interesting ROM is a CM11 port of KitKat 4.4.4 for the Wiko Rainbow. It still has bugs and is still some steps from getting usable on a daily base. The latest stock version (4.4.2) has some minor bugs (imho) too and is flawed by design. The battery stats are very inaccurate (sometimes they drop from 25 to 0 in one minutes) and other users complain about WiFi issues or less good mobile connections. Your choice. Its also stable but I for now prefer the 4.2.2 Jelly Bean on my Wiko Rainbow.

I thought about sharing how I did it from the scratch. After a loooooooooot of bad tryes. Here is how it went. All in all its pretty easy...:

The following article explains:

- Prepare the Wiko Rainbow for rooting (USB-Debugging, Unknown sources,...)
- Install the latest official Wiko KitKat 4.4.2 or Jellly Bean 4.2.2 Stock Rom
- Root the Wiko Rainbow Jelly Bean (JB) 4.2.2 via APK (Easy going!)
- Root Wiko Rainbow KitKat (KK) 4.4.2 via KingO Root (Also easy!)
- Implement an recovery for further ROMs or other uses
