Could be the ROM, the kernel, the radio or your APN settings. I know mine connects nearly instantly at boot (90% of the time by the time my lockscreen comes up I have 3-4 bars ... the other 10% of the time it takes about 10-20 seconds for it to show up).

Have you mucked around with any system files (/system/etc/*) or build.prop settings or done a lot of dirty flashes? My most recent setup is a 4.3 ROM and I did a full wipe and have not had any issues with the radio connecting to the network.

Also, is yours a T989 or a T989D? I remember a while back reading about a firmware thing for the T989 that most people were recommending updating via kies then re-rooting and re-flashing ROM/Kernel to get the firmware updates, but I don't have the link. There was a CWM flashable firmware update that was floating around, but it did not work with the T989D.

I have the t989 and if I use the uvli4, I believe it is, it connects immediately but gets less speed than the uvmc6 radio. Not much but less

alright... so i've done my fair share of testing before I decided to post this looking for help

after flashing a combination of ROMs with either MC4 or MC6, i'm still experiencing terrible call quality

phone conversations are always stuttered or random gaps occur during the call where it just goes silent for a few seconds and neither end can hear each other

i've spent over a month testing this trying to determine who's the culprit... whether it was phone, ROM, radio or cell provider and i've concluded that its just the combination of Wind combined with this phone

I've tried my SIM on other phones (t999 and i9250) and call quality was perfect - so SIM card works fine

I've tried using other SIMs (Fido, Bell and Telus) on my phone using a combination of ROMs (liquid, CM10, slim, PA) with MC4 or MC6 and call quality was perfect - so phone works fine and no roms/radios are to blame

I even tried flashing a couple older radios (LI4, LH1), but for some reason those radios can't connect to Wind anymore

My sister was the only other person I know that is using Wind w/ the T989... and she ALSO complained about the call quality before I finally just bought her the Galaxy Nexus

which only leaves me with one conclusion:

the sgh-t989 does not work well with Wind in areas outside of Toronto

Can anyone confirm this? Does anyone have another other suggestion?

Until this morning, I never attempted the telus radio. I flashed it an hour ago. AWESOME for me. I am in southwest Missouri - Rural. My internet is E, unless I am in JOPLIN or Arkansas. On ANY other radio my speeds range from 15 to 35 kb/s. After flashing telus, my speeds are between 120 and 250 kb/s. It has greatly improved my connection to my Wi-Fi network, also. I don't know how or why, but it has.

You obviously need to go study some geography. My terrain is mountainous. I live a half mile from the freeway. No there is not a large population but we are not in a cornfield in Nebraska. Some people have the crappy network towers and are asking for help to improve their reception. I asked for no help. But you were, obviously, referring to all of us. I moved AWAY from the big cities in So Cal because of the overwhelming abundance of assholes. Big cities suck.

It's not funny to criticize someone for asking for help. When you mention people's regions in a response to someone else you are talking about those people. In the other thread you tried to make me feel retarded and it didn't work for you there either. If you cannot comment with an actual useful post then don't comment. Because of back and forth crap like this these thread's become clogged and then it is harder for the ones looking for help to find it because they have to deal with these useless comments

Big cities = crowded streets, pollution, over priced tiny living spaces, etc...

When you put that together, the majority of people forget how to help others and not try to put someone down with idiotic remarks. And THAT = an overwhelming abundance of disrespectful people.

[T-Mobile Samsung Galaxy S II SGH-T989] d33dvb:
I just wanted to share my experience. I was thinking the TLmc4 radio would be ok on my t989. What resulted was a hard brick, no device connection with computer at all. No button combo would let me into download or recovery. I did try the usual trick, take battery out, hold buttons, release power on first vibrate, etc. What finally worked was power it on with it connected to the computer. It lit up, I then pulled the battery and it continued to stay on. I did the three button salute and released the power on the first vibrate, but without the battery in, it continued to vibrate with nothing on the screen. I put the battery in, while holding the vol+/- again and voila, download mode.

I was able to get out of this radio brick that way. I was stuck at Samsung screen, no recovery or odin. I hope it helps some poor soul. This veteran couldnt believe i bricked it.

Just a heads up, soon I'll be consolidating my GOO.im folder and the links to all of the radios will be put into one universal SGH-T989 folder, need to sort it out and make room for my CM-10.2 mako builds, but fear not, the radios will still be hosted even though I haven't had this phone for over a year ;)

Just a reminder, if there are new radios out please let me know so I can add them to the repository..

I was using TWRP 2.6.0.3, I did choose wipe cache and loaded the radio zip in goo manager. I only mentioned what happened because I have never seen this unbrick method, It was different than any other brick I have seen, no button response at all, meaning no recovery, no download, no pc recognition or beep when plugged in. The samsung screen was on. It would power on to that screen and go no further. I think the key was plugging in to an outlet, taking out battery and then samsung screen stays powered on. If you hold power vol + and - and release when it reboots, except this time, no samsung screen will appear, it will just vibrate over and over. pop the battery in while holding vol+ and vol - and voila -- Download mode!
[T-Mobile Samsung Galaxy S II SGH-T989] d33dvb:
Ok, I want to report back, the "brick" I had I think was related to TWRP 2.6.0.3 not the radio, as I just realized recovery was broken, odin'd over TWRP 2.6.0.4 and all is well in hercules land again. What a trip, sorry for the false report. Stay far away from 2.6.0.3

Have had this for a while can't seem to fix it. I get a call and after answering I have to wait a good 10 seconds for then to hear me. Tried tlmc6 and uvmc4 no change. Could it be the phone it self? Do I need to send it in or is this unheard of
[T-Mobile Samsung Galaxy S II SGH-T989] bmg002:
I have the same issue, but I had this issue on stock as well. I had the issue when I first got my phone and just passed it off as my carrier being delayed with making the connection. Are you on Telus?

If you didn't have this problem when you first got your phone, you could try reverting everything to stock (ie use Kies and go to stock everything) and see if that fixes it. If so, then it is probably your ROM or Kernel.

Or try going to a touchwiz based ROM as those should be closer to stock than non-TW ROMs. So most any 4.1.2 ROM sitting out there. I wouldn't be surprised if it is one of the ports causes a slight delay.

OR do you have any audio processing turned on? It could be a delay in the audio processor starting or switching tasks (like DSP manager).
[T-Mobile Samsung Galaxy S II SGH-T989] screamline458:
T-mobile, on Jedi Knight 6. Idk, I rooted and flashed the day I got it so couldnt know. I tried to flash with kies. It gave me gingerbread and wouldn't update, something was funky.
[T-Mobile Samsung Galaxy S II SGH-T989] bmg002:
Kies is goofy if you are rooted and have a custom recovery... I think then you need to trick it into doing a repair flash to make it happy.

But the delay when answering I've noticed with almost every ROM and even had that when I was on stock. I think it could be carrier delays not ROM/Kernel related... but I could easily be wrong. Maybe we both have goofy phones :P
[T-Mobile Samsung Galaxy S II SGH-T989] fathertomany:
Use the tut to revert to stock and then use kies. The delay, I think, is because of the radios as well as the towers.I can't get past bit.

[T-Mobile Samsung Galaxy S II SGH-T989] DataHawg:
Thanks for posting this thread. My wife just got this phone and her phone call sound quality is really bad, too. It has the ICS Update on it. UVLE1 I believe. She never had GB on it so we don't know if the update is what's causing the issue. Last night I was at work and told her to open her phone app and look for that noise suppression setting. She said there was no such setting. Anyway, I think I will root her phone and try some of these modems. She doesn't really care about data speeds so maybe I should flash a GB modem to see if that helps.

I am not an expert, but i read tons of pages here on the forums, i see people like you that need better WiFi stability....

My 2¢, seems to be the OS, ive read numerous comments about that, people just go back to 2.3.6.

That what i would say to you, i like the 2.3.6 better also, i like some of the TW touches too, like the option to keep the soft buttons completely off.

just Odin back to stock 2.3.6, push CWM, and flash SU.

The radio in question is for the Skyrocket...The ATT variant of this phone. So it is not going to work properly for you. What you want to do is download the UVMC6 radio from the OP. It IS the correct radio for CM11.

Battery Life: Battery life on these devices isn't great to begin with... Try turning off all unneeded features... Excess widgets, lower the screen brightness, etc. I have also found that by disabling location settings until actually needed helps tremendously as well. There are other things that can be done as well to help with battery life, but one step at a time here...
[T-Mobile Samsung Galaxy S II SGH-T989] monkeybuttons:
Agreed.

Also, it is recommended that you use Odin or Kies to install the latest available Samsung firmware on your phone (this will upgrade the radio firmware as well), then flash an AOSP rom using usual means. Flashing the modem in recovery will not upgrade certain firmware elements in the modem hardware. Only Odin or Kies can upgrade those elements. If your phone didn't come with 4.1.2 Samsung Touchwiz stock rom installed, your phone firmware likely isn't up to date, which has been shown to cause problems with AOSP roms above 4.1.2.
[T-Mobile Samsung Galaxy S II SGH-T989] ChinchilaO:
Thank you

My phone is totally geld, i remove everything, even some system apps, i use 10% of brightness, etc.

But just now i figured out the CM11 could be the problem, and im looking for the latest stock rom(t989) or some ohter good rom(for battery life).

Any tip?

And is UVMC6 the latest stock rom?

I know the part of "looking for" and "HOW" to install the "latest available Samsung firmware" is for me, but do you have the straight shot links for me?
