[T-Mobile Samsung Galaxy S II SGH-T989] RealPariah:
Ok here are some notes,

After initial clean flash using F2FS:

My Wi-Fi would not connect in Setup Wizard it saw my Wi-Fi and let me enter a password, but would refuse connect. Once I skipped and got past the setup Wizard it began fully working as expected [trust me I put my password in a half dozen times in setup wizard].

Then my mobile data half the time I boot it works as expected the other half when booted if I go to settings>Mobile Networks it states on screen that "These settings are not available to this user..." and that's all it shows. I can recover it sometimes by either fully connecting to a Wi-Fi and disconnecting or in settings disabling and re-enabling the Mobile networks toggle.

OH, also, if you have manually modified your device partitions via a PIT file (see thread in Android Dev for T989) everything works fine [as it should this is device level and not that virtual partition change crap]. I just went with the provided 5G Internal "SDCard" and left it at that. I do want to try to also modify System partition size since I have 32G micro SD I really don't care about internal storage [need a gig or 2 just in case], but besides the data being enlarged if we can also get system enlarged as well that would be sweet and really help keep this device forward compatible. It would not need to be much added space only 1 G added would suffice I think. Just enough for it to be able to handle further Gapps size explosions (something is up when your "added" stuff starts to become larger than most System images don't you think Google?). Sorry not trying to go off topic just adding this here as I bet there are some users who are wondering about the manual device level partition adjusts being OK and they are.

When fully working this ROM rocks, it just seems there might be a small issue or 2.

Thanks for a great ROM, I will give the new kernel a shot...

Also, I have a good amount of Android experience as what you would call a power user I have compiled my own ROMs and even in the distant past had one of my own that I customized and modified rather deeply, but alas my Android system coding skills are lacking so while I can normally find workarounds to most issues or help to identify where they are coming from I am not able to just dive in to the code and have at it.

Note: 1 last thing I have yet to see work it's what is called Dual Cell or Dual Carrier. In Short this is a newer HSDPA+ technology [has been available since like Android 4 I think definitely had it working all the way in to 4.4.4]. Where Carriers that support it [T-Mobile does (it's spreading as towers are under a fast paced upgrade over next couple years)] The device actually connects to two separate cells and not only can load balance, but can also use both links in combo increasing speeds AND help with building penetration as well. In android you will see DC next to your mobile signal indicator to show when in this mode. Since trying Lollipop [5.0 5.0.1 and now 5.1] it seems this is no longer supported. If it is at all possible to address this would be AWESOME. Speeds theoretically can be 28 - 42 Mbps currently and future advancements will get it to 84 Mbps (again theoretically). Would be awesome if it could be addressed if at all possible (can live with H+ just would be nice to have).

Soo far after flashing new kernel [I was soo lazy I did not wipe cache or Dalivck cache as I should have and it still boots fine by the way :) ]. Both the Wi-Fi and Mobile Data connected INSTANTLY on boot before my homescreen was even up so it is looking gravy YAY!! THANK YOU FOR THE FIX (soo far). I will keep beating things up to see if anything goes wrong, but roughly an hour in and my phone is still happy.

I will report back hopefully this evening with findings for you.

Again thanks for getting the fix out quickly :beer: :beer: :beer: :beer: :beer: :beer: [Six Pack wwwoooo], You ROCK!!

I will look for one, but is there a donate link around here somewhere I ain't rich, but will definitely buy you a real beer man!
