[Q] - T989 on ATT network - T-Mobile Samsung Galaxy S II SGH-T989

Everything seems to work relatively well with my current unlocked device on ATT. Only problem is data seems kind of patchy (speedtests show it just spiking and dropping like mad, have to hit retry frequently when loading pages or surfing the app store, etc). I am using the ATT APN settings based around the wap.cingular stuff that seems to be the most common. I average around 1mb speeds so my question is would I benefit from finding a different radio for this setup? If so which one should I try?
Device is running the Darkside venom ICS build. Thanks.

I plan on going to a straighttalk sim. Which would be off att (that's the sim I want) and I'm going to keep the ice cream sandwich kernel on it ulve1 I believe it is. I would NOT flash an att radio. I believe that would brick it.

I guess i'll just keep on cruising along. It seems to work alright but if there was a way to squeeze more power out of this bad boy I'd certainly take it.

False, you can interchange between SR and herc radios kernels and roms. Just don't odin anything.
Btw to op. Sell your herc and buy a SR for cheaper + using LTE = profitx2

Not according to mr vlad.. which makes sense cause of LTE. Plus for me i cant get anybodys LTE where i live.
Unless the Herc ignores the LTE frequencies using that radio?

I didn't think the ST plans supported LTE, so SR on ST isn't any benefit over the T989?
To the OP, you might check out here:

Folks are posting tmo and att ST speeds. There's an off chance someone from your area may have posted att speeds for you to compare to.

But one can still flash an att radio and the Hercules would ignore the lte? Or would flashing a sr radio brick the device?

OK, why do folks have an interest in flashing skyrocket stuff onto the T989? Just get a carrier unlock from TMO, get an ATT or ST ATT sim, and pop it into the T989, talk away. What am I missing? What does the SR have that the T989 doesn't?

Brick the device, they're interchangeable. Herc does not ignore lte. They don't even pick it up.

For faster data and stronger signal you want an att radio which is design to optimize those bands.
SR has LTE. other than that they're identical

its ymmv, the stock radio can pick up H+ on AT&T but for users who have slow data, flashing AT&T radios helps. Unless you're just trying to prove me wrong or something.

Trying to find some data. Something like "on att with tmo radio I get 2 MbS download, but same phone on att with att radio I get 4mbs".
I know that different combinations of radios and roms can improve reception in some areas.
I also haven't seen anything that indicates the MAGNITUDE of the difference.
I get that sometimes, maybe, if you're having trouble with your current reception, you might be able to get better reception if you flash some other radio. (from your current carrier or a different carrier)
BUT some folks think that they should almost routinely flash their T989 to an att radio if they want to use it on ATT. I haven't seen it help at all on my phone.
So my question is two fold, what is the MAGNITUDE of the difference, and, how OFTEN does it make a difference. I was hoping someone had some data on that.
Thanks!

What do folks using the T989 on AT&T use for Radio?

I my self have a Skyrocket on AT&T. But I bought one for my mom, a Tmobile T989 which is unlocked and she uses it on AT&T. I have it configured to use the right AT&T APN and it shows up as 3G but the best I get speed wise is maybe 2.5meg down. Im thinking it needs to be somewhere in the 5-8meg range for at least just 3G/HSPA.
I have the latest LDE installated and its modem and same results (as prior 2.3.6 version, cant remember which modem that was).
I saw Mr.X's thread on different flashable modems, but wanted to see what others have used and got say good 3G/HSPA+ performance on it via say AT&T.
I basically see Tmo UVKL1 being recommended as the best or the Telus KJ3 for dual channel HSPA (maybe thats why im not getting past 2.5meg down).
Thank
Dixit
an att radio would be best for atts network
Wanted to make sure that was possible and not brick this phone. I know the two are fairly similar, but didnt really notice in that other thread any of the Skyrocket modems so thought maybe they are either not compatible or not recommended.

Alright will give it a shot. Right now the T989 using the LDE radio gets me service on AT&T and no real issues with the exception as I said about not getting more than 2.5meg down. I will try that last maintenance leak Skyrocket radio we got on the 2.3.6 and see how that goes.

Dixit,
What modem did you end up with for the best speeds? I have the t989 and a net10 sim, on ATT, ready to go.
Will a skyrocket modem brick the t989?

Let us know how it goes! I'm curious as to the result because I thought sky rocket radio would at least keep from booting. But the radio might just ignore the lack of lte and btw my Co worker just ran a speed test on 3g with att and got 1.2mps.

Adding my experience here now that I'm on net10 with AT&T:
Tried Tmobile UVLE1 and Telus modems (see Tdj's modem listing thread). Speeds seem to be the same on both. Battery life was better on the Telus modem but a lot of my calls sounded like a modem connection. If I rebooted I could make a call and it would sound fine.
So for now I'm back to UVLE1.

have you tried AT&T radios?
No, I'm afraid to brick. I've not been able find strong references to anyone trying it and living to tell the tail.
I've done a lot of searching on the forums though and the 2.5 to 5 Mbps I'm seeing are consistent with others reports of Att, Straight Talk Att, and Net10 Att speeds. Additionally, I've done many speed tests with my buddy, who is using Att's S2 and the speeds are consistent.
At this point I have to believe an Att radio would do no better.
Hope this helps,

I been thinking...instead of messing with all that and end up with a brick, why just not sell it on ebay and buy an actual Tmobile one or maybe trade with someone willing to. I would look at the selling price for an AT&T GS3 on ebay and how much would a Tmobile run and if it's not that much difference then pay the difference than end up with a possible brick. Plus I have read some forums where if you flash some things that are not meant for your phone you can even mess up the IME on your phone with no way to flash it back at the moment until someone comes up with a solution for it.

When I put my friends note to t mobile it was the modem you had to flash , if your set on doing it , read a bunch on ways to do the note WITHOUT a custom Rom then find the same files you use in that ( the modem and if I remember right there was one other thing ) then go to the t mobile section in the sgs 3 thread and ask for help finding those files , but do a lot of reading first cause it would be a shame to brick your awesome phone

I seriously wouldnt count on it. The two networks run on different technologies. Im pretty sure the hw is different due to this.
Sent from my SGH-T999 using xda app-developers app
Have you guys tried the radios in the dev section by wildchld? I'm not sure it will work either but maybe worth a try. It has a script that backs up current radio and you can revert back. Atleast on T-Mobile s3 it does. Just need to reflash the restore zip to go back to previous radio. Again try at your own risk. There's a huge chance you can brick your device.

Just remember that was a different phone. And tmobiles radio Im pretty sure was confirmed to NOT support LTE. So they are different.
I'm definately looking forward to hearing someones results after trying! Just do some research on the two radios, and make sure the sw modem is on the same partition for each phone. (I think it will be. But if its not you could end up with serious problems)
Good luck to whomever tries it!

i would like to know which one would be preferable among the two !
i will be using the phone in india so the phone will be gsm unlocked !
what i would consider :

2) build quality, audio quality, camera quality
also pls mention the differences between both phones !

Yes this is true.
Qualcomm's MDM8220 modem doesn't support LTE.
"Qualcomm’s MDM8220 dual-carrier HSPA+ solution, based on the 3GPP Release 8 standard, provides peak downlink data rates of up to 42 megabits per second (Mbps) and 11 Mbps on the uplink, allowing carriers to easily upgrade their existing infrastructure equipment to achieve significantly higher bandwidths. Its dual-carrier technology doubles networks’ bandwidth from 5 MHz to 10 MHz by aggregating two HSPA carriers in parallel.
The MDM9200 and the MDM9600 chipsets are the industry’s first multi-mode 3G/LTE solutions that allow UMTS and CDMA2000® operators to upgrade seamlessly to future LTE services while preserving backward compatibility to their existing 3G networks. MDM9200 supports UMTS, HSPA+ and LTE, while the MDM9600 supports CDMA2000® 1X, EV-DO Rev. B, SV-DO, SV-LTE, UMTS, HSPA+ and LTE. All of the new chipsets support FDD LTE and TDD LTE modes and different carrier bandwidths, and are capable of using orthogonal frequency division multiple access (OFDMA) and multiple-input and multiple-output (MIMO) antenna technology to support peak data rates of up to 100 Mbps on the downlink and 50 Mbps on the uplink."
Wow...I'll be honest with you that was quite a mouthful lol you kind of lost me so I read it twice and I understand, but pretty much the Herc has the MDM8220? So thats a no on the LTE if when T Mo gets LTE like they plan on, we wont be getting true LTE. Correct me if Im wrong lol, Im just a noob trying to learn.

Unlocking Q

If I unlocked my Hercules and used at&t prepaid and flashed a skyrocket radio would I be able to use their data? And also would the data be just as fast?
Sent from my SAMSUNG-SGH-I727 using xda app-developers app
Yes I think so might just have to change APN settings
How do you do that?
Sent from my SAMSUNG-SGH-I727 using xda app-developers app
I'm not for sure you may not have to. I only know how to change APN on a iPhone. You should be OK with just an unlocked t989 and radio change
I believe you could use it, but it would only be 2g because at&t uses LTE for their high speed networks. The physical radio itself in our Hercules just doesn't support it.
Sent from my SAMSUNG-SGH-T989 using xda premium
But a att radio should fix that
No, not the software radio. That will give you the 2G signal, but we don't have the actual physical hardware to run full speed on at&t's network. That's part of why the Hercules has a different processor, the one in the international/att sII wouldn't work with tmo's hspa network.
Sent from my SAMSUNG-SGH-T989 using xda premium
You would be able to use your Hercules on AT&T but if the fast data you're referring to is 4G LTE, then no, you won't get that because the Hercules doesn't have the hardware needed to support it. You would get HSPA+ though.

No. You could turn off 4G and get EDGE/2G though.
On Verizon phones you can turn off 4g to only use 3g why would it not be the same

T-Mobile's 3G/4G networks run on the same bands so you can't block something on one band and only let the other thing work. I guess Verizon has different bands for 3G/4G.

Follow this guide. Works perfectly. I used my i-317 on T-Mobile for a while before I traded it and got great 4G speeds.

No, it permanently unlocks those bands, just like carrier unlocking a phone. Once it's done its done.

Yeah, pretty sweet stuff. And like I said, I got really good data speeds. Before I did the mod I was stuck on Edge, afterwards I was pulling down like 15+ Mbps download and 3+ upload speeds.

No. The T-Mobile version, T-889, is a dual cell phone capable of supporting 42.2 Mbps data transfer. The AT&T version, i-317, is not and is limited to 21.1 Mbps. However the i-317 is capable of using more than one LTE band whereas the T-889 is limited to just one.

OK so what how does using more than one LTE band benefit the end user?

No, you can flash other carriers roms. The thing is you have to make damn sure what you're flashing isn't gonna brick you. From a software standpoint all Note 2's are the same, for the most part. You have to be careful not to flash another carriers modem or you'll have no signal. If that happens just flash an AT&T modem and you're good. The kernel is pretty much the same. There might be some minor differences but nothing to worry about. Just read read read. All the info is in the OP, and if it's not just ask in that thread.

You can flash tmobile roms no problem. You'll also have access to wifi calling if you're carrier is tmobile. I'm using my at&t note 2 on tmobile. Lte and h+ on either carriers roms.
