I would like to thank/recognize the following people for their contributions:

@Chainfire - For SuperSU
@nyfl2004 - For our working Viper4Android, 3Minit Battery and Clock modded to the V20, and for all of his help with getting Aroma up and running
@ivicask - For looking through my convoluted Aroma setup and helping identify why it was randomly breaking
@topjohnwu - For his most excellent Magisk and MagiskSU apps allowing our rooted devices to pass SafetyNet and catch 'em all!
@AllTheWay - For providing me with the AT&T system dump needed to port my customizations over, and being my guinea pig to get it booting
@Tilde88 - For all of his work in getting a stable kernel going for the V20, and allowing me to include it in my ROM
@USA-RedDragon - For his Werewolf kernel, and allowing me to include it in my ROM

Current Known Issues:​
H918
Some people have experienced skips when listening to music over Bluetooth. I too have had it happen, but it is not at all common, and lasts less than a fraction of a second. Putting your phone either on vibrate or DND seem to help further reduce occurrences.
H910
4.0 is based on 10L, not M, as my dump of that one would not boot. WiFi Calling and VoLTE do work, however.
All Variants
Data Wipe option in Aroma doesn't always work. This is a glitch related to newer hardware and Nougat, as verified on the HTC 10 as well. If you expected your data to be wiped, but it was not, please reboot into TWRP, perform a Factory Reset, and then flash the ROM again. You MUST flash the ROM again after a factory reset, or you will lost systemless root AND your internal storage may encrypt.
Netflix - They have blocked their app from unlocked/rooted devices. You can sideload it from APK Mirror, or use Magisk to hide root from Google Play Store, then clear data on the Play Store. Your device will then show as Certified and all blocked apps will be available.
As any more come up, they'll be added here, and then fixed ASAP.

Pre-Install Steps​
If you are not already on TWRP 3.0.2.0-RC8 or higher, do that first! Bootloops and loss of access to recovery is possible with all older builds
Backup your existing ROM
Notes​
I recommend wiping data and flashing clean, if coming from another custom ROM. This should not be required, but you may wind up with FCs if you don't. A clean flash is required if you're on an older custom ROM, or older stock based on 10d.
If you're already on an older build of my ROM, you can dirty flash future updates. However if you experience FCs, please do a clean flash

Changelog:
v5.0 T-Mobile
Updated base to 10K (May 2017)
Added Google Pixel Launcher from Android O Beta 2
Updated all Google Apps except Maps
Reverted Maps due to GPS issues for some
Updated Aroma to 3.00 Beta Downgraded back to Aroma 2.70RC2 in fixed build
Cleaned up the app lists somewhat
If Aroma freezes during the install, pull the battery and start again - this only happened to me once, in over 30 test flashes
Rearranged some of the menus for better flow
Spent a good 4 hours rewriting the installer-script to make it look a lot less ugly
Added Werewolf kernel by @USA-RedDragon in place of NotSoStock
Available without root as well
Further tweaked the memory utilization in build.prop, allowing background apps to remain in RAM longer
I think there's a few other changes, I just can't remember them at the moment. Roughly 20 hours into this update, brain is mush.
NOTE: Due to the changes to memory utilization in build.prop, your first boot after the update may cause the phone to lag. This will clear up within 5 minutes, and will not occur after subsequent reboots.
v4.0 T-Mobile
Added New Options for No Root Installs
Stock and NSS kernels available without root
3minit and V4A options still work
Updated all Google, LG, T-Mobile apps
Updated Nova Launcher
Updated Magisk to 11.6 (12.0 finicky on V20)
Removed Adaptive Brightness mod (was glitchy)
Several additional build.prop tweaks
Added Optional Apps
Google Voice
SMS Backup and Restore
Speedtest.net
Removed Pixel Launcher - Assistant interferes
v4.0 AT&T
ROM base updated to 10L (10M won't boot)
Added New Options for No Root Installs
3minit and V4A options still work
Removed Werewolf kernel
Updated all Google, LG, AT&T apps
Updated Nova Launcher
Updated Magisk to 11.6 (12.0 finicky on V20)
Several additional build.prop tweaks
Added Optional Apps
Google Voice
SMS Backup and Restore
Speedtest.net
Removed Pixel Launcher - Assistant interferes
Now some notes and observations:
There was a report of the ROM not froze at the AT&T splash. If this occurs to you, first wait 5 minutes to make sure it really is frozen. Then, pull the battery and then boot up again. The Android is Starting screen will then come up as expected.
There was also one issue where the ROM wouldn't boot past the AT&T splash. For this, boot into TWRP, flash the AT&T boot.img (attached to the download post) using the IMG flash option, then flash Magisk 11.6 (also attached), then reboot as normal. I'm also uploading a patch to AFH, which should automate this process. Give it a try and report back.

Yeah, I was big into development in WM 5 and through to WM 6.5 up until I got the Droid X in 2010. It's gonna take some time, but I'm getting back into development as a whole.

Feedback
@NotATreoFan great job bro, bootup was fast as you advertise, wow, no lags or stutters i can say so far, only issue for me is that some LG apps need to be put back in, namely the LG app updater as Home and App apk has an update as well as the weather widget and Memo for the capture feature, but other than that for me its definitely a good start for a DD, thanks

Great work on the ROM!
Question, how did you get the post-install apps to not install?

I think it's from one of the LG items I removed. Going to experiment tomorrow morning and see if I can make them install again.
I also realized that I accidentally removed Calendar Storage, so that'll be fixed tomorrow as well.

@NotATreoFan thank you for this broham!!!!!
I just flashed Tilde88's latest and after a night of testing his tonight I will be flashing yours to test out. You all are so highly skilled and keep up the unbelievable work.
When I'm up and running with yours tomorrow I will report back and do a comparison of the 2 ROMs.
If there is anything I can do as far as testing holler at me, I'm down to tear up my phone.
Again, thank you and keep em coming baby!!!!

i got the post-install apps to stop installing by changing the model number in the build prop the the US unlocked version.
Also to the OP how the hell did you get the ROM to deodex successsfully every time I do it i get stuck at the TMO boot animation

It's not deodexed yet. That's my plan for today, along with some bug fixes.

---

oh ok. Yeah every time i've done it with superRs kitchen i cant get past the TMO boot animation. Someone did successfully do it as there is a rom up thats deodexed.

you know the bravia reality engine thing the other rom has. Do mods like that (framework) require that the rest of the ROM is deodexed? I know apps needed to be deodexed for editing but didnt know if it affects other mods.
Usually just do CM stuff

---

Is there any chance you can upload JUST a system IMG? I'm seeing if I can get this working on the US996...

I don't believe you need to have the complete ROM deodexed, just the parts you're modifying. But I could be wrong since I've only done this a few times.

As soon as I get the latest test build booting, I'll make a system.img and you can try it. There really shouldn't be a reason it wouldn't boot. It just may behave weird if there are files it's not expecting.
