Toying with trying out Gummy since you've got the ee4 update going now.
Quick questions
Already running AB4.1.1 and I haven't installed ee4 at all. Will flashing to Gummy install e4 or will I need to flash stock and OTA for it first?
Here is the quick and dirty instructions on going from a rooted ED2 install to a Rooted EE4 with GummyCharged
1. Install ED1 Root Odin found here on XDA (make sure you deactivate voodoo if you have it activated)
2. Boot and let it OTA you to ED2 (stock)
3. download the EE4 update found on this site and put it on the root of your SD card.. Rename that file to update.zip
4. boot into stock recovery and select install update.zip.
5. let it do its thing
6. after booting and verifying that everything is working on EE4, install CWR from this thread via Odin
7. Install a root Kernel via Odin or CWR for either voodoo or non voodoo depending on whether you want or know how to activate it.
8. install Wipe data
9. Install GummyCharged
