- If I can not Flash over the stock, can I make my ROM slot 1 OS have a bigger partition? I need more then 2GB of free space for apps. If thats not possible, I was thinking of backing up and then building a new ROM slot with more space.
- Can I harness the whole of the drive, TW rom slot aside?
Also as a side question, I managed to delete the stock messaging app from my GPE OS, I was trying to install the CM one from the play store. It crashes on boot of the app, so i removed it and now stock sms is gone. I tried to pull the APK from my GPE rom, but it would not install.
You can wipe out stock slot and only have the one rom on stock slot with no other slots taking up space.
At first this wasn't possible, but now that the backup image is out there, you can always restore to the stock samsung TW rom if anything messes up.
So unless you actually wanted to 2 OS's to switch between, I would just delete all the rom slots, and put whatever rom you want in stock rom slot. although it can only be the 4.2.2 GPE edition or TW based, but I assume you know that already.
