"If you're worried about the shutdown affecting your service, relax. T-Mobile is not getting rid of HSPA, HSPA+ or 3G in any market. All the markets where T-Mobile is dropping AWS HSPA are ones where T-Mobile has deployed HSPA on the 1900 Mhz band as part of its network modernization project in 2013. Only HSPA on AWS is being eliminated, HSPA will still be available on the 1900 Mhz band, which all recent T-Mobile (and AT&T) phones support. If you have an LTE phone, the speed and reliability of your LTE connections should be improved in the 24 markets that are getting more LTE bandwidth."

edit:

Just contacted my provider (Ptel), they said they will be using 1900/2100.

cm4.4 installation

hi trying to install 4.4 kitkat rom on my t-mobile galaxy s2 it keeps aborting the install and gives me a Status 7 i hav e tried 5 differnt versons of the rom . I did a wipe of data /factory reset and wipe cache before trying to install rom . It is rooted with CWM recovery v5.0.2.6, please help thanks for great roms
[T-Mobile Samsung Galaxy S II SGH-T989] obscuresword:
I think you need to update your recovery first. Mines is CWM version is v6.0.4.3. Also make sure you are running the most recent radio for T-Mobile.

Nice! I'll have to take a shot of my next great battery life. Once, with my old LG G2X, I got nearly 48 hours standby with about 1.25 SOT! I took a screen shot, I'll have to try to find it.

I've used Privacy Guard to block the Google wakelocks and seems to be working well. The services you mentioned, I disabled now . What about the other Google location services listed in Disable Service app? There are many.
[T-Mobile Samsung Galaxy S II SGH-T989] ArtfulDodger:
It seems you pretty much have to disable anything to do with location services, or risk losing deep sleep. Now today battery was going back after booting up so in addition to the others I had to disable Google Location Service again also (I turned it back on for Transit app and Google Maps). I left Location Manager on for trial & error purposes, but may need to disable that too. If I have to just manually enter location each time then I guess so be it. This is super annoying and I would almost consider removing Google from my phone altogether if not for Google Play.
[T-Mobile Samsung Galaxy S II SGH-T989] cameraddict:
I was blocking with Privacy guard as well- disallowing it permission to keep device awake-.... until a few weeks ago. I assume a new version of GooglePlayServcies(GPS) installed because all of the sudden blocking GPS from keeping the device awake started to cause it to unexpectedly quite.... ALL THE DAMN TIME! it became almost possible to do anything. I was constantly closing the dialog telling me it had quite. That's why I went in search of another solution and settled on Disable Services app. It works for me
[T-Mobile Samsung Galaxy S II SGH-T989] ArtfulDodger:
Just FYI T-Mobile is having major service issues in Kentucky and Indiana, lost service for the first time since having T-Mobile tonight: https://downdetector.com/status/t-mobile/map/
[T-Mobile Samsung Galaxy S II SGH-T989] cameraddict:
I was having major issues in Downtown LA last night as well. COULD NOT connect. Could not maintain connection once established. All the while saying full bars of service. Absolute worst no service event since I joined them when they were still PCS One back in 1999!

Back to KK from L

hi can someone teach me how to flash back [MENTION=4800121]Sultanxda[/MENTION] Android 4.4.4 KK from [MENTION=4800121]Sultanxda[/MENTION] Android 5.1.1 Lollipop.

I find this http://xdaforums.com/showpost.php?p=59093149&postcount=611 but dont work for me, or i do something wrong. Can somebody do step by step tutorial for noob ? TY

Trying to connect to PC guys. Having a hard time. Tried USB and MTP mode . The PC constantly connects and disconnects. Tried different cables but that didn't help. Windows update even gave Samsung drivers which I downloaded and installed. Help is appreciated.
[T-Mobile Samsung Galaxy S II SGH-T989] LimeliME:
Try clean the phone connection port with a brush or something (pull your battery out and hold power button for 10 sec because you don't want to get shocked while doing this)

If still dones't work for you then try reflash the Rom again (it could be some error occurred during the Rom Flash) or try another Rom

I had then same problem and tilled the usb cable upward while connected to the phone seems to solve the problem for me.

If all above didn't work, it is possible that the connector has malfunctioned (S2 component do seems to be failing right now) [Unless you had other solution to this then feel free to reply, I'd like to know another solution towards this problem too :)]
[T-Mobile Samsung Galaxy S II SGH-T989] ArtfulDodger:
Good grief no service yet AGAIN depending what area of Louisville you're in. Just a few block from where I live, no service. Hell maybe I shouldn't worry so much about another phone and should think more about switching carriers.
[T-Mobile Samsung Galaxy S II SGH-T989] cameraddict:
Curious, have you been calling tech support when ever you experience the outages? If there is enough downtime, I've had them credit my account for a day or two of service for lesser outages than I had last week. Also, I suspect these are growth pains. I hear many cities are starting to undergo network upgrades. (maybe this is related)
[T-Mobile Samsung Galaxy S II SGH-T989] ArtfulDodger:
Yeah I have heard that also, however there are some instances (or areas I should say) where I live that are densely populated but have a horrible signal. Where I was at yesterday has had a weak signal before, but this time I couldn't even get a signal. Soon as I walked another block it was back to full strength. Hope it gets better but at $40 a month it's hard to find other options too unless I want to pay more.

No Play store after update

So... I dirty flashed over Oct build. I cleared cache and dalvick. Everything seems to be working except... everything google needs play services which stopped working. So I uninstalled it's updates. I got a notification to install the newest version, but the play store keeps saying that I have no connection. Doesn't matter if I'm on network data or Wifi. It just won't connect to the play store

Any suggestions?

edit--

I tried removing my account and reentering it. Alas, now the account setup says that it can't establish a reliable connection to the server. But... I can connect to the internet with other apps...
[T-Mobile Samsung Galaxy S II SGH-T989] LimeliME:
Try flash the Gapps and try again (few months old but might still works)
[T-Mobile Samsung Galaxy S II SGH-T989] cameraddict:
Thanks. What I wound up doing is restoring my backup. Then went through the whole install process again. Seems to be working now.
[T-Mobile Samsung Galaxy S II SGH-T989] cameraddict:
I'm thinking this ROM doesn't like the dirty flash. I've been having issues left and right over the last 24 hours. Some of which can be resolved with an uninstall and reinstall of a problem app. I'm also experiencing abnormal battery drain compared to my exact same setup using the Oct build. I really didn't want to go the fresh install route right now.. but it looks like that is my only option short of restoring my Oct build's backup. At least my phone was stable with pretty decent battery life before this.

Any thoughts? Did anybody else dirty flash with success???

Thanks
[T-Mobile Samsung Galaxy S II SGH-T989] eric93se:
I never had good luck dirty flashing.

I'm wondering if my battery is on its way out, seems to drain far faster now when doing simple things. Battery "spin test" lol tests good (ie. no bulging).
[T-Mobile Samsung Galaxy S II SGH-T989] ArtfulDodger:
No, trust me it's the damn Google Play services. I was thinking the same thing as my battery was draining much faster the last few months. Just disable most of that crap (especially location related stuff) and disable analytic service in Play services after every boot. My battery went from 20 hours to anywhere from 36 to 48 hours during normal weekdays when there is light use.
[T-Mobile Samsung Galaxy S II SGH-T989] cameraddict:
Well, as we had quite a bit of conversation pre my dirty flash, my battery was really good after enabling the GPS Update service. But after the dirty flash (with exact same same setup and and of course dealing with the GPS update service) I get about 20-30% less battery life.

I have a crazy week ahead of me, so I won't be able to trouble shoot any further until after next weekend. But I think I will try a fresh install and get my phone back to the exact state it is at the moment without old data weighing me down. If the battery is the same, I'll assume it is this version of the ROM or Kernel. And then, I will just deal with it, because Hangouts dialer is finally working properly! No unexpected closures and I can finally use the device dialer without a reboot. And...the people I'm calling generally say the quality is better. This is enough for me at the moment.

Issue with Camera and cropping

With the Oct build, I was able to compose images in the camera and know exactly what I was going to get on all four sides of the image. What was on the screen was all I got.

With the last build, the image has much more information than I saw on the screen. Like the screen only showed 80% of the captured image.

Has anybody else seen this?

Perhaps it doesn't matter, since this is now in the bone yards.
[T-Mobile Samsung Galaxy S II SGH-T989] ArtfulDodger:
I take a few pictures here and there for Ebay & stuff and haven't noticed this, what I do see on the screen is exactly what I get after I take the picture (using stock camera). I will say for this phone's faults the camera is one of the highlights.
[T-Mobile Samsung Galaxy S II SGH-T989] cameraddict:
I have been ecstatic with the camera on this phone using this ROM. But this issue is bizarre! It makes it nearly unusable for me as I compose images to use for print on occasion.

Hearing that you're not experiencing issues, combined with the problems I've been posting about it... I think I just need to start fresh, and wipe the phone.

Thanks for continuing to check in on this thread, ArtfulDodger.
[T-Mobile Samsung Galaxy S II SGH-T989] Who.is:
I instaled this rom and all works fine , but i have big problems with camera, in recording video at 1080p i cant zoom and focus doesnt work in video recording befor and after pressing record button. And in taking photos the whole phone just turn off after capturing photo, its FLASH the scene and black screen and phone is death. This is stable version? and in feature list is fully function camera and video recorder but its fully bugs.
[T-Mobile Samsung Galaxy S II SGH-T989] ArtfulDodger:
I guess each user has their own issues, fortunately this doesn't happen to me. BTW I was able to get ART running today for the first time. I had given up months ago but since the kernel got updated I figured I'd try again. Went off without a hitch, well sans YouTube. I had to install a modified apk to get it running again. Battery use during SOT is waaaaay down now. Only at 83% after one straight hour and that's with texting, email, browser, Neutron and Viper all running. That's about 8-10% better than before.
[T-Mobile Samsung Galaxy S II SGH-T989] cameraddict:
I'd given up on ART as well. Maybe after my fresh install, I'll give it a whirl! Where did you find the Youtube apk?
[T-Mobile Samsung Galaxy S II SGH-T989] ArtfulDodger:
I had it saved from about a year ago, you can still find it here: http://ultimarom.com/themed-apps/youtube/
[T-Mobile Samsung Galaxy S II SGH-T989] cpnfantstk:
Artful. Have you had any luck connecting your phone to your computer?I've tried MTP and mass storage but the computer keeps disconnecting the phone. Thanks
[T-Mobile Samsung Galaxy S II SGH-T989] ArtfulDodger:
Yes several times with no problems. Do you have the Samsung drivers installed on your computer?
[T-Mobile Samsung Galaxy S II SGH-T989] cpnfantstk:
I do. I got them from windows update. Which ones are you using? Strange that MTP and USB Mass storage are both giving me issues. Drive letters would show up and then disappear. Tried different cables but no luck.
[T-Mobile Samsung Galaxy S II SGH-T989] ArtfulDodger:
I have used both but prefer USB mass storage. Sometimes if the phone is disconnected either without safely removing & then turning off mass USB mass storage, or disconnecting the phone prematurely before this process is done this causes issues later although you should be getting a pop-up saying there are problems with your SD cards if that was the case.

Hi,

Planning to downgrade from CM12 to CM11... anything I should be made aware off?

What should be the correct procedure to clean phone before flashing this CM11 rom?

EDIT

I did advanced wipe and checked system and now i am getting a "error executing updater binary in zip..."
[T-Mobile Samsung Galaxy S II SGH-T989] ArtfulDodger:
Disappearing data and APNs

Anybody losing data connection and all APNs at random? Twice now that has happened, and on top of it when I try to reboot it just stays on "rebooting" and I have to force it. Before a reboot fixed it, now today it doesn't. Not sure why now this is happening but I guess I have no choice but to move on to PA 5.1.1 for good. Man I can't wait to move on from this piece of junk phone too.
[T-Mobile Samsung Galaxy S II SGH-T989] cpnfantstk:
That's strange. That happened to me on Saturday. No signal for a short bit. I also had to do a battery pull because the phone got stuck on reboot. Everything's OK now though. Maybe wipe Dalvik/Cache might help you.
[T-Mobile Samsung Galaxy S II SGH-T989] ArtfulDodger:
See my post in the Wild! Kernel thread, I've moved on to official CM with Wild. Working very well ATM.
[T-Mobile Samsung Galaxy S II SGH-T989] cpnfantstk:
Thanks ArtfulDodger. I've checked that kernel out but what rom do you flash with it? Does VIper4android work with it? That is a must for me. BTW.. when you are ready to move on to a different device , go to the slickdeals website and get pricing alerts . That's the best way to get a nice deal on a handset.
[T-Mobile Samsung Galaxy S II SGH-T989] ArtfulDodger:
Believe it or not, just use the latest official CM nightly found here: http://www.cmxlog.com/11/hercules/. I am still amazed how well this is doing. I never even bothered to test the built-in kernel but I would have serious doubts about stability based on past history. Barring anything else that comes up, I am done using any more ROMs on this phone. I think LP development will quit here pretty soon anyway. And yes, Viper works just fine too. I flashed everything using the latest TWRP, and in this order:

1. 7/12 CM Nightly

2. PA 4.4 Gapps

3. GPS Mod

4. SuperSu 2.46

5. Fly On Mod packages

I let the phone boot up, set everything up, then rebooted and installed the Wild! kernel. The kernel doesn't install on initial flash of ROM, so you have to boot up first, then reboot and install it.

Thanks for the tip on that site, but I am already dead set on the ZenFone 2. Only a great bargain on a superior phone would change that.
[T-Mobile Samsung Galaxy S II SGH-T989] eric93se:
Well, parting is such sweet sorrow. My t989 is in the hands of another, sold it for the same price I got for a year and a half ago. Craigslist FTW, no seller fees, no shipping fees, no paypal fees. I also listed it on swappa and ebay. But the new owner will never appreciate or understand all the hard work that the Dev's put into developing the OS of this device, he will just be like "Damn this phone works great" (once he gets a sim card for it lol). I got an awesome deal on a LG G2 D801, the owner put a screen protector and case on it from day one and it was pristine (until I got my hands on it lol). T989 people! I have not had to wipe the screen from greasy finger prints NOT ONCE! in over a week of use now. /clouds parted/ /angels sing/

While ROMs are pretty good for the LG G2, you might want to check if the D802 (international) might be a little better than the D801 (tmobile). I started out with cloudyfa's 4.4.2 ROM (older but very mature) with a pretty bad-ass kernel by Dorimax, and now have moved on to a new CM12.1 rom. They also have simple mod's to flash to get all the volumes bumped up. Originally the dorimax kernel could do that in the kernel tweaks app he made, but now with CM12.1 I had to just flash a zip in recover and everything is plenty loud. I does suck no having battery access or a removable SD card but I'm pretty good without it, I guess eventually I might setup my own cloud if I need it.

[T-Mobile Samsung Galaxy S II SGH-T989] kepler1729:
Wow! I just got an e-mail on this thread, which I thought was dead lol. I'm glad you put in the effort; I myself have moved on to a Note II (t0lte, or SGH-T889), but props! If I ever bring my S2 back to life, I'll definitely have to try it out.

One thing though -- wouldn't this be better served for the Lollipop builds? I mean, I doubt anyone really uses CM11 with this device anymore; the only active devices left are probably all CM12.
[T-Mobile Samsung Galaxy S II SGH-T989] javelinanddart:
*shrugs*

Maybe small fstab and ramdisk mods are needed to make it cm12 compatible tbh

they share same kernel

My herc is half broken so it doesn't like Lollipop, so I'm using CM11

Sultan's kernel was nice but a little under featured for my tastes so I pimped it out
[T-Mobile Samsung Galaxy S II SGH-T989] ArtfulDodger:
I have used both Trickster and Performance Control, they both work fine but I think I like PC a tad bit better. Advanced kernel settings are typically never available in the stock performance settings.

BTW on the extra features, I feel the same. All the features in the world don't matter if your phone isn't working the way you want it to. Most of that stuff is cosmetic and I have all kinds of workarounds to get any missing features I need to work either through other apps or scripts (like call blocking, RAM optimizations, etc). I also can do without RRs and freeze ups if it means doing without "features". Peace of mind however is priceless and so saving a few hundred bucks on another phone.
[T-Mobile Samsung Galaxy S II SGH-T989] Sultanxda:
I'll look at it and maybe add it next weekend.

Display undervolting is only available from the Aroma installer because I wrote the feature. Aside from what's given in the Aroma installer, my kernel has pretty much no features that users can configure. There aren't any CPU governors or I/O schedulers that you can play with, ultra-fast charge is already enabled by default and cannot be disabled, etc. I'm not really into adding a bajillion CPU governors and I/O schedulers, or features for users to play with in general. The fewer things you can play with, the lower the chance that you can break something. This ROM and kernel are built so that you don't have to spend hours playing with a bunch of sketchy settings or scripts to get your phone to work well.
[T-Mobile Samsung Galaxy S II SGH-T989] ArtfulDodger:
Amen to this! The only governors that really seem to work well on our phone are Performance, Interactive, Ondemand and Intellidemand. I've tried them all and the others just seem to clutter up settings as they cause nothing but freezing and headaches. On schedulers I notice zero difference in most of them so might as well go with what works 99% which is Deadline and Noop. Though I think SIO, BFQ and Tripndroid are decent ones too.
[T-Mobile Samsung Galaxy S II SGH-T989] Sultanxda:
New ROM build uploaded with kernel v1.4.0. The kernel is now using the newest audio drivers and GPU drivers available :) I tested phone calls and various other things with the new audio drivers and everything seems to work. If you suddenly start getting a zillion force closes (emphasis on a zillion) with the new build then please be sure to report it. There was a memory leak in the past when I used these GPU drivers, but it should be fixed now (so your phone shouldn't explode with force closes).

Note that these new audio drivers don't fix the Hangouts Dialer issue. That issue is a tough'un...

EDIT: I made an oopsie and need to re-upload the ROM. Programmers always find the most mistakes in their code right when they release it :silly: If I leave it as it is then your device will be as slow as the official CM nightlies.
[T-Mobile Samsung Galaxy S II SGH-T989] ArtfulDodger:
And of course I have already updated... :(
[T-Mobile Samsung Galaxy S II SGH-T989] G2XPerson:
About the Hangouts issue, I don't have the Dialer installed at the moment, but still encountered the non-working regular phone call audio issue after having had successful video and voice chats through Hangouts. It wasn't until I rebooted the phone that regular call audio functioned again.
[T-Mobile Samsung Galaxy S II SGH-T989] Sultanxda:
On the bright side, I'm adding in 1 more massive driver upgrade to the kernel to increase performance: newest-available Ion memory drivers from CAF kk_2.7-stable. These are the same memory drivers used in my 3.4 kernel, so my 3.0 kernel is a pseudo 3.4 kernel ;)

Argh, I hate the modem software on this device. If this is an issue in the audio HAL in the ROM (like the "Ok Google" issue) then I cannot fix it as I am a C programmer. The audio HAL is coded in C++.
[T-Mobile Samsung Galaxy S II SGH-T989] crazydude10:
Is the new version a cherry picked version of latest cm 11 ?
[T-Mobile Samsung Galaxy S II SGH-T989] ArtfulDodger:
Cool beans, thanks. For what it's worth, things seem fine so far. If I can get by without updating the ROM again until next time I will, as it's kind of a process for me to restore a few scripts & system apps. I will definitely update the kernel again though once you post it. That sounds like another big step forward.
[T-Mobile Samsung Galaxy S II SGH-T989] e20140:
Haven't try the latest.

But I went back to the 1st Kernel v1.3.5 after testing v1.3.8. Battery on stand by mode is no wear close to v1.3.5 (0.2% drop /hr) vs v1.3.8 (0.9% drop /hr). No google play service disabled.

Looks to me the extra feature you added by request might have caused the extra drain!

I personally don't use BLN nor Sweptowake.

Can anyone comment on v1.4.0 battery life on stand by?
[T-Mobile Samsung Galaxy S II SGH-T989] tuxx1337:
I found a possible solution for this here. I haven't experienced the problem in a long time so I can't confirm if it works or not, but you may give it a try.
[T-Mobile Samsung Galaxy S II SGH-T989] Sultanxda:
October 5th build and v1.4.0 kernel uploaded :)

The changes from v1.3.5 to v1.3.8 are pretty minor, nothing there that would cause significant idle battery drain... Idle battery drain has *always* been 1%/hr for me.
