Wow, rather long post I typed last night just up and disappeared.
Flintman confirmed that flashing his hybrid TWRP using CWM first deletes CWM before installing TWRP. So, my theory is that if done the right way, you should be able to install any of the 4.4/3.xx/data-media kernel Roms using his TWRP. Here is what I propose:
1. More or delete as much as you can off the current SD card, as you are going to use Tailor to move most of the memory over to the data partition. One way to do this would be from WebOS/settings/reset options, reset USB drive. Run Tailor and set up the partitions as suggested by the developers. If I were doing this, I would leave a gig or two for WebOS to use.
system - 600mb( or maybe even 700mb)
cache - 200mb
media - 400mb(leave a gig or two here)
data - [remaining space] (i.e. ~11.5gb for 16gb TouchPads)
2. Run ACME5 to install just Moboot and CWM
3. Use CWM to flash Flintman's hybrid TWRP.
You will find it on the OP here:
[ROM] Evervolv | 4.0.0p1 [AOSP 4.4.2] [3.4 kernel] [Nightlies] With /data/media - xda-developers
4. Flash one of the 4.4 data/media Roms from Flintman, Milaq and Invisiblek and the Gapps of your choice for KitKat.
Remember when switching between CM and Evervolv, the uImage is not named the same. I believe Flintman said that when you install Evervolv, his scripts are built to remove CM, but not the other way around. So I would suggest running ACMEUninstaller2 and doing a clean install of each Rom using Flintman's TWRP. And yes, I believe ACMEUninstaller2 undoes all the partition size changes you made with Tailor.
As far as I understand, none of the ACMEInstallers will install a data media Rom. That is why one has to use one of the special recoveries. And now you know why I am not particularly interested in trying any of the data/media Roms. Although, Flintman is still supporting an Evervolv 4.4/3.xx kernel that is not a data/media build, at least for now.
If you choose to accept this mission Grasshopper, I disavow any responsibility for any reboots, bricking, or black holes created by trying this.
