[Galaxy S 4 Active Android Development] Devo7v:
You are going to single-handedly save this phone, and I appreciate all the time you're putting into this. I've installed the GPE ROM and then flashed the Aroma package and I've noticed a couple things:

On the welcome page (the page after selecting the theme) for some reason it mentions "Xperia MFPI Devices..." I'm not sure if this is hardcoded and needs to be changed or not.

The MasterPatch Changelog need a little formatting.

Under the patches, I would say somewhere (possibly in red) that the patches are required to be flashed on first boot. This way a new user will make sure those boxes are checked and won't have a reason to complain that the ROM isn't working. I would say something like "These patches are required to be flashed before the first boot of the ROM. Make sure all three boxes are checked." Another option would be to call them "Required Patches" rather than just "Patches". Or, and I don't know if this is possible, have the boxes checked by default so that the user has to uncheck them intentionally.

I don't know if it's worth it, but maybe the option for other gps regions? I know that this is for the i537 that was pretty much only sold in the US, but if you go on Sammobile there are i537 builds for Mexico and Uruguay.

I'm not sure the confirmation box for installation is needed since there's no way to cancel it.

On first boot of GPE there are no APN's listed. I did select the option in Aroma to flash APN settings, but for some reason it didn't take.

Default camera works fine, but that is to be expected since this ROM was built for the Active. I flashed the camera fix regardless.

I hope I'm not being too critical, I think you've done a great job with this and I think it will really help the community.

The only other thing I would add is the AT&T Compatibility Pack for Hyperdrive. The only trick with that is that you would have to make sure it is the last thing that is flashed in Aroma, otherwise it won't work and the APNs will be wrong. I took a look at the pack and noticed there were a ton of files in there which I'm guessing are there because it is based off a Verizon ROM. That said there may be a couple other things in there that are needed for the APN settings and might fix the problem with your patch.

Let me know if you need me to test anything or if I can help you out with anything.

EDIT: Just noticed the LTE MMS fix for Hyperdrive isn't an option. I'm not sure if this is still needed or not since I use Google Voice, but maybe under the optional patches there should be a Hyperdrive option that will flash everything needed for Hyperdrive.

I would also make sure things are being flashed in the correct order, if that makes sense. I'm thinking the APN settings might need to be flashed last, but I could be completely wrong about that.

Two other options I thought could be added to this:

T-Moble AWS fix/APN settings

Google Wallet fix. I was able to get it working on my stock slot, I'll have to find the guide I used and post back here later with it. Here are the instructions, reading over them I'm not sure that it's possible to just flash something and get it to work, but it sure would be nice.

Thanks again for doing this.
