This research is not entirely done yet

was anyone able to confirm for sure if we can load a TMO radio on the Skyrocket, and get it to work as HSPA+ on AWS 1700/2100 ?
[T-Mobile Samsung Galaxy S II SGH-T989] GBGamer:
Yes, I'm pretty sure that they said this somewhere around here.

I told you guys weeks ago. There is absolutely no LTE hardware (chipset, amps, filters, antenna) in T-Mo SGS2.

Props for being dedicated and trying it anyways.

Just a thought here some1should try renaming the phone under the build.prop and see if it makes a difference (name it a phone that gets lte for real). Just a thought

After seeing your pics though and doing some research on the chipsets, you were right. You and heygirl were kinda asses about the whole thing though. Something useful could have come from testing, you never know. Your whole I know more/am superior thing ruffled some feathers, so I'm not surprised by the reactions you got. Infraction seems a little much though.

Can we just be all friends? :)
[T-Mobile Samsung Galaxy S II SGH-T989] heygrl:
I wasn't angry, I don't get angry over the internets. I was disgusted that even after several common sense statements, OP and others still progressed on with the strong belief that it had LTE. That was just one thing, even on this page OP still has hopes for LTE, and believes that the T-Mobile modem blocks out 850/1900MHz HSPA+. Really though.. this is supposed to be XDA-Developers, not the T-Mobile support forums.

Like I said, sloppy Samsung. Anything LTE that shows up on the T-Mobile GS2 are simply artifacts of it being closely related to the Skyrocket.
[T-Mobile Samsung Galaxy S II SGH-T989] y2whisper:
Soo back to the final experiment. Confirming you can get hspa+ (I assume u are looking for dual cell hspa+) on a skyrocket. We know u can get it on telus/bell and 3g can be achieved on the aws bands. So it sounds like it can be done. Just need someone to confirm.
[T-Mobile Samsung Galaxy S II SGH-T989] hnt20:
here is the fact. the phone supports lte for sure check out the spec of the qualcomm chip. Tmo has disabled that. Lte radio +ROM changes will surely get it working.
[T-Mobile Samsung Galaxy S II SGH-T989] KenpoAP:
And this can be achieved by...?
[T-Mobile Samsung Galaxy S II SGH-T989] :
I would like to know that too. I flashed skyrocket late modem and it ether killed my base and or only gave me edge speeds. Toggled band selection but nothing. Had to Odin kl1 to fix my base band.
[T-Mobile Samsung Galaxy S II SGH-T989] jordanishere:
Your questions have already been answered. Read the thread :).
[T-Mobile Samsung Galaxy S II SGH-T989] Haxel:
Com chipset is not the same... T989 has the MDM8220.

I would be curious the pro/con of buying a skyrocket and plugging TMOs ROM on it... trying to figure out how usable it is.
[T-Mobile Samsung Galaxy S II SGH-T989] AznDud333:
assumng theyre in the same type of socket, we can probably buy the chip from qualcomm, desolder it and solder in the lte modem
[T-Mobile Samsung Galaxy S II SGH-T989] KenpoAP:
If you're talking about mine... and only if you're talking about my specific Q... The only current answer is tha lte is not part of the T989 hardware... So in that particular case how was my question answered? The guy is saying that it is still possible to activate lte by changing a couple of things in the rom code... What specific things are needed to be changed in order for "LTE" to "properly" work in this specific device...?
[T-Mobile Samsung Galaxy S II SGH-T989] :
+1. yes I have read most of itbinclduing the tests those guys did. If it is locked then please explain how to unlock it. Question was not answered.
[T-Mobile Samsung Galaxy S II SGH-T989] Haxel:
It is not possible to "activate LTE" because the com chip is NOT the same as the rocket. Plus antenna would have to be changed out as well.

They may be using the same pingrid/PCB between the two models so de-soldering and placing the MDM9220 chipset on board may work... theoretically then it is just a matter of the antenna. Again, theoretically...

There is not an "unlock" for the Hercules to use LTE. I am enjoying the fact it should be able to do 3g on AT&T 850 band as well as TMO AWS.
[T-Mobile Samsung Galaxy S II SGH-T989] seanyuan62:
Is anyone here running the Tmobile network on a unlocked Skyrocket? Would we get H+ and what radio would we have to flash?
[T-Mobile Samsung Galaxy S II SGH-T989] :
While it would be awesome to be able to use LTE bands, I am not one for taking my 500+ phone apart to "theoretically" find out if it ll work. I was fine with isntalling FFC on Vibrant but not this.
[T-Mobile Samsung Galaxy S II SGH-T989] y2whisper:

and of course the t-mobile sim.
[T-Mobile Samsung Galaxy S II SGH-T989] quest4fire:
Thanks to everyone that tested. Even though we had some folks that stated the hardware doesn't allow LTE it was a worthy experiment.
[T-Mobile Samsung Galaxy S II SGH-T989] Watcher64:
"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."

Now as much as I would love to think/say we can do LTE, this pretty much spells it out ...
[T-Mobile Samsung Galaxy S II SGH-T989] :
Or that we can somehow get fm radio? Ive seen something similar posted on skyrocket forums that fm radio was blocked?
[T-Mobile Samsung Galaxy S II SGH-T989] :
I lol. Its like posting scientific evidence and saying the world is round , and having people call you a heretic and put you in jail.
[T-Mobile Samsung Galaxy S II SGH-T989] y2whisper:
I think the way it came out from you milan (but more so others) is where some took issue. i.e. there were others that claimed people where lying or fools. At the same time yes you did bring facts, people still wanted to try to remove all doubt and did.

Much like anyone who shoots down an idea on an online forum, the line has become so thin between factual claim and trolling. kinda sucks.

Still more research to be done but not in regards to LTE on the T989 - looks pretty closed to me.

The biggest thing we did learn, if you are on t-mobile and could score a skyrocket over the t989, go for it.

and chib, the world is flat everyone knows that. :)
[T-Mobile Samsung Galaxy S II SGH-T989] heinrich:
Yawn :) bottom line, Skyrocket may support T-Mo HSPA+ as well as ATT LTE. Right? But sgh-t989 supports HSPA+ and no LTE.

Sound right?
[T-Mobile Samsung Galaxy S II SGH-T989] AllGamer:
Guys keep this on topic

keep all personal chatters on a separate topic please

on the original R&D point people were able to confirm the LTE issue, or rather the lack of LTE as it was expected from the chipset

but we still need to confirm the last R&D point, if the LTE version of the phone can be flashed to work on AWS or HSPA+, wince the LTE is using the band that is reserved for AWS

we still are waiting to hear back from the test results, unless it was posted already
[T-Mobile Samsung Galaxy S II SGH-T989] johnny13oi:
So has anyone confirmed that the ATT Galaxy S II Skyrocket works on Tmobile's 1700Mhz AWS band for 3G (4G) internet?
[T-Mobile Samsung Galaxy S II SGH-T989] Haxel:
I really have not seen in the specs if it supports the 2100AWS either... supposedly from the chipset side it does.
[T-Mobile Samsung Galaxy S II SGH-T989] mbucks911:
wow never seen a manufacturer being modest about their phones and say that they have less then they do. good for them!
[T-Mobile Samsung Galaxy S II SGH-T989] dkotoric:
Well according to the skyrocket forums there are a few people that just had to root their phone and flash a Tmobile radio on the skyrocket and they have working 3g/4g on tmobile. I'm very hopefull for this cause I inted to get a ATT Galaxy Note and do this as it uses the same chipset as the Tmobile GS2 and Skyrocket.

Looks like this case is closed also then :p
[T-Mobile Samsung Galaxy S II SGH-T989] SGS2X:
This thread actually turned out to be a half-success since we discovered that the Skyrocket can run on AWS. I think it's important for more people to be aware of that because it opens up more options when buying phones and whatnot.
[T-Mobile Samsung Galaxy S II SGH-T989] AllGamer:

indeed, if i would have known ahead of time, i'll have gone for the i727 instead of the t989

just so i can take advantage of the LTE or AWS depending on the cell phone provider i feel like using

Guys, neither the Telus or T-Mobile radios will work, if you wanted to even test LTE, you'd need to find someone who has an LTE phone on one of those bands, and flash a skyrocket radio.
[T-Mobile Samsung Galaxy S II SGH-T989] SGS2X:
I mentioned this before but didn't get a reply :P but in that thread where i posted, someone before me said that they were just there but had no function.. but if we can flash a rogers/at&t modem to check, that would be crazy :o

[T-Mobile Samsung Galaxy S II SGH-T989] mikeyinid:
Yup, and itll never work on att lte anyway. IF it is lte capable it would have to be on the tmobile network. Were probably a year or two from tmobile deploying lte.
[T-Mobile Samsung Galaxy S II SGH-T989] Longcat14:
Not nessecarily, I've flashed T-Mo modems before, and nothing.

Actually, it has Band 4 and Band 17, which is what AT&T uses for LTE, so it should work with a Skyrocket modem unless it's locked somewhere in the hardware.
[T-Mobile Samsung Galaxy S II SGH-T989] mikeyinid:

[T-Mobile Samsung Galaxy S II SGH-T989] Longcat14:
Yes I did, and Samsung phones aren't like HTC phones.

Flashing a bad or wrong radio won't brick your phone, since it doesn't touch the SBL (where download mode).

All that would happened is that you would have no radio access, which is easily fixed by flashing back a T-Mobile radio.

And our 2 phones are literally exactly alike, if I can flash a T-Mobile radio, you should have no problem flashing a Skyrocket radio.

I flashed the Rogers Skyrocket modem since it not RAT locked to my Telus T989D, seems to work fine. Just throwing it out there for people who think this will brick, it will not.
[T-Mobile Samsung Galaxy S II SGH-T989] Longcat14:
Yeah, we need them to shed some light on this. :)

Long as it's the same radio as the Skyrocket, then it's software locked, which flashing a Skyrocket radio would fix.

Only way to lock the LTE radio would be for Samsung to ask Qualcomm to lock it in the hardware, which I doubt they did.

Just put a different SIM (not the carrier SIM) in the phone, and it should pull up, I don't see why it wouldn't.

I think the people who think it'll brick used to be HTC users, because flashing a bad radio onto a HTC phone will **** your phone up.

Thankfully, Samsung doesn't associate the radio with anything in the bootloader, so we are fine. :)
[T-Mobile Samsung Galaxy S II SGH-T989] -Mr. X-:
Yah, Radios made me wary as well since i used to be htc.

Anyways, flashing the rogers radio, i can now select LTE bands and it sticks. instead of flopping back to automatic.

So i assume its seeing the lte firmware included in the modem flashed to the modem partitions.

Rogers doesn't have LTE in my hick ass town though, which is why i am Telus in the first place since they do have HSPA+ here
[T-Mobile Samsung Galaxy S II SGH-T989] jordanishere:
So curious to hear if this works. I'd try it myself but T-Mobile wont unlock my phone until 90 days have passed as I am not on a contract with them.
[T-Mobile Samsung Galaxy S II SGH-T989] Longcat14:
That's stupid, off contract phones, they should give you the unlock code as soon as you ask for it...

Yeah, just remember, you can **** with radios on Samsung phones, just don't touch the SBL (download mode), or your screwed. xD

And nice, it sticks now? I guess the Skyrocket radios work!

I have a Rogers SIM card I can use to test.

Question: do I have to enable "LTE" option with Rogers (and potentially pay a little more) to be able to use Rogers LTE, or am I automatically eligible to use LTE as long as I have a data plan and as long as I'm in LTE covered regions?
[T-Mobile Samsung Galaxy S II SGH-T989] RuizGT:
Dumb question, but what kernel would I need to use with the skyrocket modem? Or would it even matter?

can i use an att kernel as well?

i mean can i flash the att sky roms and just boot? i havent tried... i guess while i wait for party goers to arrive i will be rom flashing...

making nandroid now... not gonna deal with problems...

/me hugs his samsung jig

i also have an infuse and sgs2 int if you guys want testing on the bit older but still awesome samsung goodies.

ps the post above me....

the attain ie sgs2 doesnt support lte, but that is the whole point att released the sky, it DOES support lte.

LTE did not work right with the 1.2ghz chipset, thus the 1.5 the sky and herc match with... so it was compatible with what lte needed and used. its not the same chipset but faster, complete diff from sgs2, just FREAKIN Awesomer....

yes thats a word... cause i said so.

will report back.

[T-Mobile Samsung Galaxy S II SGH-T989] -Mr. X-:
I'm positive that the telus Hercules has the hardware behind it for LTE, infact in radio debugging logs i can see it doing LTE commands, Telus just has not fully or even partially launched LTE in my area. Its most likely going to have LTE enabled with the ICS update they are advertising, the difference in what frequencies and lte bands it can use is in the radio. I've already proven this by flashing the rogers radio, it lets me select LTE and it sticks (with the telus radio LTE is not selectable) but i get no signal on the LTE bands as i have none in my area. I also lose HSPA+ when i flash the rogers Radio and my "4G" speeds are cut in half as it is not dual banding HSPA.

The phone DOES indeed have the hardware though, the ril is doing LTE functions in the logs right down to the fact that my computer detects the4 device as a samsung LTE modem when i plug it into linux.
