uhm, so yea, flashing sky kernel works, flashing sky modem does not, gives me no service, what did i do wrong?

and of course i can not find a tmo modem to save my life to flash to go back..

not brick, just no service no matter what i do, what apn i use, etc.

im using skyrocketer rom on tmo herc, currently on tmo kernel... and sky modem....

i just wanna flash the tmo modem i had for now...

ideas?

http://www.ponack.net/TPC/dagnarf/cwm-tmob-kl1-radio.zip <- T-Mo radio from Da_G

That's really weird that the Skyrocket kernel didn't work, but it could be due to the fact that Da_G packaged the RIL with all the modems, could be messing with something.
[T-Mobile Samsung Galaxy S II SGH-T989] -Mr. X-:
I flashed the rogers modem with the ril files and it worked 100% fine for me. So I'd assume that the reason its not working for that user is the radio has defaulted to a band that he does not have in his area (LTE, GSM or WCDMA) The issue with the ATT modem is its RAT locked so you cannot switch what bands its using. I'd try the rogers one.

This explains why my windows 7 pulls up LTE modem in the list when I plug in my phone the first time
[T-Mobile Samsung Galaxy S II SGH-T989] killster:
current status for now.

phone : tmo herc

rom : skyrocketer

kernel : Jugs tmo ver

modem: kl1 tmo ver

service: att (speeds match my att sgs2 )

back to a WORKING phone ... gracias :)

ill mess with it a bit more later, wife is up and asking me to clean :(

thank you for the modem sir.

i was about too but read ATT people saw horrible speeds, but ill give it a shot, i did only try the RAT locked modems (both).

for now im working.
[T-Mobile Samsung Galaxy S II SGH-T989] Longcat14:
If you don't mind, when your not busy, flash this modem.

http://www.m-s-j.net/skyrocket/Radio_RIL__I727RUXKJ7.zip

That's the Rogers modem that isn't RAT locked, that should let you pick what band you want.
[T-Mobile Samsung Galaxy S II SGH-T989] killster:
Will do. I'll give it a shot shortly and report back along with speeds
[T-Mobile Samsung Galaxy S II SGH-T989] -Mr. X-:
I'll assume it will work.

The whole reason Samsung used this quallcom chipset is because theirs does not support LTE.
[T-Mobile Samsung Galaxy S II SGH-T989] Longcat14:
They have an LTE chipset, it's just that the Exynos isn't rated for LTE compatibility, so they can't just slap it on. Why they used a QC LTE chipset, probably because the second gen chipset is really thin.

The Exynos 4212 was designed with LTE in mind, so that would work, but that was destined for the Galaxy S 2 HD LTE.
[T-Mobile Samsung Galaxy S II SGH-T989] mikeyinid:
Depends what carrier your on the reason they used the quallcom chip. T-Mobile obviously doesn't have lte so that's not their reason. T-Mobile went with the qualcomm chip because the exynos chip doesn't support hspa 42.
[T-Mobile Samsung Galaxy S II SGH-T989] Longcat14:
Yeah, and AT&T needed an LTE chipset, which the Exynos doesn't support.... sucks honestly, because the Exynos 4212 supports HSPA+ 84 AND LTE. :/
[T-Mobile Samsung Galaxy S II SGH-T989] Watcher64:
From what I have read on the TMO and AT&T Radio, is it is software programmable , it is the exact same radio, it is not hardwired for specific bands, so this does look good for the future of the TMO&ATT roaming/band sharing agreement.

If someone has a Skyrocket radio running on a TMO GS2 , give a shout out which radio, I will be in an LTE area later next week and would love to test it ... Even if I can't connect , if it "Sees" it, that would be hope ...

(in the mean time I will try to find a att sim card to test with if the radio works)

Alright, flashed that modem through cwm, changed my apn settings to these: http://www.traemcneely.com/2011/12/...rottle-4g-data-anti-throttling-trick-for-att/

but, still not connecting to any data, any thing else I should change?

edit, just re-read the apn settings from that link, it's for hspa+ trying to find correct settings now. :|

For those that flash an alternate radio. Try flashing it twice. At first my speeds were ****. Now they are flying with the telus radio.

[T-Mobile Samsung Galaxy S II SGH-T989] minhajmsd:
The hd lte also uses the qualcomm not the 4212
[T-Mobile Samsung Galaxy S II SGH-T989] jordanishere:
This sounds correct, considering the phone was being designed at a time when T-Mobile and att thought their merger would work.

Also it makes sense for Samsung to create one device and ship it to att, T-Mobile, Rogers and teleus since they are all north American carriers on similar bands.
[T-Mobile Samsung Galaxy S II SGH-T989] y2whisper:
Bell. Which supports dual channel hspa+ (the same that telus uses)
[T-Mobile Samsung Galaxy S II SGH-T989] Longcat14:
Maybe for HSPA+, but the roaming contract never said anything about LTE, which I wouldn't be surprised, I doubt AT&T would like for others to roam on a network better then their own, and hell, I doubt T-Mobile would like that.

[T-Mobile Samsung Galaxy S II SGH-T989] y2whisper:
tested today and my rogers s2 LTE works on wind 3g with the T-Mobile radio. (Uses the same aws band) so it appears we have a software locked pentaband device indeed. Which is fantastic.

This is terrific news!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

---------- Post added at 03:40 AM ---------- Previous post was at 03:39 AM ----------

It means it is almost confirmed that our phone has LTE hardware support. Just need to flash Rogers LTE modem.

HOLY **** OUR PHONE IS AMAZING!!!!!!!!

Someone needs to edit the subject of the OP to say "confirmed" so that everyone knows about it.
[T-Mobile Samsung Galaxy S II SGH-T989] jr_718:
Would be nice if someone would post a tutorial and some picture testing. Thanks.
[T-Mobile Samsung Galaxy S II SGH-T989] :
um Qualcomm stated this themselves its not really hard to find out this information. https://developer.qualcomm.com/discover/chipsets-and-modems/snapdragon it is listed under the s3 processor multimode. The s4 just has world mode which is that it will work around the world on other lte networks.
[T-Mobile Samsung Galaxy S II SGH-T989] xsteven77x:
Am i reading this wrong or does this say they got an LTE device to work on 3g? Are we not trying to get our tmobile 3g to work on LTE? It is progress none the less, but not exactly what we were going for...
[T-Mobile Samsung Galaxy S II SGH-T989] heygrl:
ugh.. the T-Mobile Galaxy S 2 does not have LTE support. You all should spend your time on something worthwhile. The LTE bands menu is INSANE, do you really think it supports all of those LTE bands? come ON now... this is the same nonsense with the Galaxy S Vibrant supporting 850MHz 3G.
[T-Mobile Samsung Galaxy S II SGH-T989] jordanishere:
This just sounds like an opinion. Do you have any facts to back this up? Other people are swapping sims, flashing radios and posting their results....
[T-Mobile Samsung Galaxy S II SGH-T989] :
T-mobile does not have lte support. The processor is capable of lte support though. While it does nothing. Really here in the U.S without an roaming agreement with lte networks. It might for other people who live outside the U.S where different frequencies are used. The actual device is no different from the skyrocket with lte support. If someone wanted to do the work they could essentially get lte support on this device.
[T-Mobile Samsung Galaxy S II SGH-T989] 513263337:
How do you know? Ridiculous...

It's amazing how people with nothing concrete can go off making him sound like such an expect.

The previous poster already proved that, by flashing our modem on his Rogers Skyrocket, his Skyrocket, which was unable to connect to 1700 before, CAN connect to 1700 now. This is good proof that Skyrocket and our phone use the same hardware, which means, in reverse, by flashing skyrocket modem on our phone, we should be able to get LTE too.
[T-Mobile Samsung Galaxy S II SGH-T989] marcopolo1:
nobody says T-Mobile has LTE, we are talking about the phone, not the carrier
[T-Mobile Samsung Galaxy S II SGH-T989] defconoi:
It would be awesome if we could force our phone to roam from t-mobile on at&t's 3g in edge areas. is there any hack or possibility to force it on at&t like old symbian devices that i could force roam. like pick a att only frequency?
[T-Mobile Samsung Galaxy S II SGH-T989] jordanishere:
If the Phone was CDMA you would flash a preferred roaming list to get the other carriers towers... aka sprint phone with a verizon .prl

I am new to UMTS/GSM so I dont know much about how this works (been on cdma all my life). You probably have to change the radio to an ATT radio like Mr. X and Logcat have suggested.
[T-Mobile Samsung Galaxy S II SGH-T989] Longcat14:
I have the exact same bands on my Skyrocket, and it's not impossible for Qualcomm, they do radios, I'm surprised it doesn't have MORE bands.

There's been proof everywhere that when flashing a different modem, the other bands activate (say if I flashed a T-Mo modem, the bands that the T-Mo SGS II use would only be active, I wouldn't get access to 850, but when I switch back, I lose 1700,2100 and regain 850).

Just goes to show, Samsung got lazy. ^^
[T-Mobile Samsung Galaxy S II SGH-T989] SGS2X:
If it turns out that T-Mobile/Telus SGS2 DO have LTE, would it be possible for someone to make a modem that enables all the bands at the same time? I'm asking because I'm currently with Mobilicity which uses AWS for HSPA+, and depending on how the 700 Mhz auction goes in Canada, they will be deploying LTE on 700 Mhz. If that does happen, I'll have to get a new phone unless our phone could handle LTE 700 Mhz and HSPA 1700/2100 at the same time. If it CAN do that, then this would be my smartest purchase of the year :D Wind also has plans of deploying LTE on 700 Mhz and if the government sets aside spectrum for the new entrants, this would fix most the signal problems with Mobi/Wind :)
[T-Mobile Samsung Galaxy S II SGH-T989] quest4fire:
Do you need carrier unlock to use LTE?
[T-Mobile Samsung Galaxy S II SGH-T989] v8dreaming:
I live in Las Vegas, which according to AT&T, has LTE.

I'm kind of confused because of all the networks that this phone works on. If I were to try to see if my phone will work on AT&T's LTE network, what radio should I odin? I know the AT&T radio is APN locked, or something?

Would my phone even be able to do anything since I'm on T-Mobile?
[T-Mobile Samsung Galaxy S II SGH-T989] SGS2X:
Yes, it's like unlocking to use on any other network.

AT&T Radio with AT&T SIM and LTE plan, or Rogers radio with AT&T LTE apn and LTE plan
[T-Mobile Samsung Galaxy S II SGH-T989] Longcat14:
*whistles*

Making a modem would require reverse engineering the radio, which would be a ***** to do.

The thing with the 700MHz auction is, you need to know what the specific frequency is (not just general 700, like 716 (AT&T) or 782 (VZW)), and if they the Skyrocket/T-Mobile SGS II don't support the LTE band, you can't force a band into a radio which doesn't have the band capability hardware wise.
[T-Mobile Samsung Galaxy S II SGH-T989] SGS2X:
Didn't know that even 700 mhz is more complicated than just that :( all i know is that it's the same spectrum that was used for OTA before channels became digital (I think lol)
[T-Mobile Samsung Galaxy S II SGH-T989] heygrl:
The antenna has to have support for the bands, of course an LTE modem would be capable of multiple bands IF the T989 had one (which it does NOT). What am I saying, there has to be an LTE antenna for there to be any LTE band support! Furthermore -- the Skyrocket only supports AT&T's 700MHz LTE yet lists all of these bands it does not which means the menu means diddly squat when it comes to actual network compatibility.

That nonsense about the bands is also a fukn lie, I have locked my T-Mobile Galaxy S 2 on 1900 and 850MHz WCDMA and it is NOT locked out from those bands on the stock modem. When I lose T-Mobile coverage on base I pick up AT&T 3G but only in emergency only mode.
[T-Mobile Samsung Galaxy S II SGH-T989] y2whisper:
Although I can't comment on locking to a specific 3g band in my test I was able to get wind 3g on my rogers s2 lte. put it on 3g only to be sure. Wind uses the same aws band as T-Mobile. Not sure how that's a lie.
[T-Mobile Samsung Galaxy S II SGH-T989] Watcher64:

If you don't think it will work, don't try it ..

[T-Mobile Samsung Galaxy S II SGH-T989] iloveandroid16:
LOL so true, sick of the trolls.
[T-Mobile Samsung Galaxy S II SGH-T989] heygrl:
What?! I said the phone being locked out of other bands when on the T-Mobile modem is a lie and it 100% is. 850MHz, 1900MHz, 1700MHz and 2100 (IMS band not AWS, you don't mention 2100MHz when you are talking about the AWS band) MHz 3G are all active on the stock T-Mobile radio image/modem.

Hope? False hope is more like it. We don't need more misinformation being spread around on the internet. LTE is a huge battery drain especially if the phone can't even use it, has no network to use it on, and it's a complete waste of money in a phone that was custom tailored for dual cell HSPA+ networks (Telus/T-Mobile USA)
[T-Mobile Samsung Galaxy S II SGH-T989] Watcher64:
The problem with your statement is , The radio in our phone is not custom tailored to our bands, the firmware for the radio is, our radio is a a software programmable DSP, which can be changed as needed.. Look up the specs ... NOW you may be right and LTE may be outsides its range, we don't know yet and the specs are not specific. Now the antenna might be, but I highly doubt it, there are plenty of broad spectrum antennas on the market, I am sure they could either make one or get one ....

Now if you want to post some hard data that disputes these claims I am sure people will take that into account, but to just start saying people are lying or that it is a waste, is actually more of a waste of your time than anyone else.

Again if you post hard facts, then I am sure we can respect that, but this is a dev community, and if we want to break our phones trying then that is OUR OWN DAMN BUSINESS.
[T-Mobile Samsung Galaxy S II SGH-T989] xsteven77x:
TELL IT
[T-Mobile Samsung Galaxy S II SGH-T989] heygrl:
Are you serious? How did you manage to get yourself on here to make a post and not end up on the other side of the internet?

I said the phone - any specific part of the phone, was custom tailored for dual cell HSPA+ networks like the ones Telus and T-Mobile have deployed, thus... the phone is packing a Qualcomm SoC, modem and an antenna (please note that the actual "antenna" part of the antenna system is only one part of the equation) that supports both carriers WCDMA bands and their dual cell HSPA network.. none of latter have LTE capabilities what so ever. LTE requires a separate antenna because of MIMO, how many times do I have to say this? The rest of your post is nearly incoherent.

/thread
[T-Mobile Samsung Galaxy S II SGH-T989] tony604:
A simple way to confirm this is to have a t-mobile or telus s2 run a skyrocket or Rogers s2 modem with a lte enabled sim. My bet would be that it works if it has been confirmed that a rogers s2 will also run wind 3G. I've done some research into cellular antenna technology in the past an this would seem the most likely outcome. @heygrl care for a friendly wager of $10? I'm sure someone will confirm for sure soon.
[T-Mobile Samsung Galaxy S II SGH-T989] y2whisper:
Not fully clear on your points here. so you are saying when using the tmobile modem you can access the other networks. i.e. getting at&t 3g with a t-mobile modem? or are you saying the complete opposite? regardless, i was just responding as if you were saying everything in this thread was a lie.

none the less my points, and the discoveries in this thread seem to be as follows.

A tmobile device MAY be able to be used on AT&T's lte network (if you had a sim and plan from them) Just waiting for confirmation

the Rogers (and therefore AT&T) LTE device can also work on Wind (and therefore T-Mobile's) 3G network which is AWS based.

FOR CANADIANS - using the telus modem can get u support for dual cell HSPA+. Rogers/at&t do not have dual cell (dual channel) but bell does (which is why its relevant to me and like 3 other people in the world) in other words im using a rogers device on bell with dual cell hspa+ support. No LTE though obviously, but I don't have LTE where I work so that isn't a problem.

WHAT CANT BE DONE

you can not get LTE if your carrier is T-Mobile
[T-Mobile Samsung Galaxy S II SGH-T989] -Mr. X-:
These devices are all LTE ready they all conform to the 3GPP Release 8 standards (Which in cellular jargen is LTE)

Telus has coined this device their flagship for 2012, its their first device they have publicly announced that will get ICS 4.0, they are pushing it like crazy and they are also pushing the release of their LTE network nation wide this year.

So the facts are this:

http://www.3gpp.org/LTE <-- read that to understand what 3GPP Release 8 is

http://www.telusmobility.com/en/ON/samsung_galaxy_s_II_x/index.shtml <--- Telus's advertised specs for the SGH-T989D

The device is ready, the network (for telus users) is not. Like i said i expect Telus to announce the Broadcasting of LTE in major city centers soon, and the ICS update will see the radio update for telus users to use the LTE bands that coincide with the LTE launch.

"Canada's first dual cell and dual core smartphone engineered for speed and power. Only from TELUS."

It is what they advertise it as, dual cell means LTE radio and the standard GSM/HSPA radio

The devices are all capable, the cellular hardware in this device is probably the broadest on the market, if your cellular provider intends to use them is another story.
[T-Mobile Samsung Galaxy S II SGH-T989] jordanishere:
Can anyone say worldphone?
[T-Mobile Samsung Galaxy S II SGH-T989] -Mr. X-:
As far as specifications it handles quad band gsm/edge and quad band HSPA so it should work anywhere provided the radio your carrier provides with the device allows you to hop to those frequencies. The hardware is there, there is no doubt about it. The telus device even advertises on there site as supporting tmobile 3g AWS as well.
[T-Mobile Samsung Galaxy S II SGH-T989] marcopolo1:
what bands my phone has?

i have a question .. i know this phone has 1700/2100 850-1900 3G bands and Has 1700/2100 HSPA+ (4G) bands... i though it has 850-1900 HSPA+ bands . but apparently it does not have.. i am in Peru now and we use HSPA+ 850 , i unlocked my phone and use my local sim card.. it picks 3G signal but not 4G , i mean , only shows 3G on top and not 4G...

So that means the phone does not have 850/1900 4G bands ? or T-Mobile modem blocks 4G network with a different sim card... however i use my T-MO sim card here with international roaming... it should 4G signal but not , only 3G .

so, i need some answers ..
[T-Mobile Samsung Galaxy S II SGH-T989] Watcher64:
Ummm ok not sure why you say my opinion is my entitlement , because I agree with you ...

Yes these phones are awesome .....
[T-Mobile Samsung Galaxy S II SGH-T989] jordanishere:
That's what this thread is about. You need radio software that tells your phone to pickup hspa+ on 850/1900 instead of umts on those bands like its doing now....
[T-Mobile Samsung Galaxy S II SGH-T989] y2whisper:
im wondering.....what are the advertised speeds for your network. I assume its just due to your network not supporting the 42mbps (someone correct me if its higher for t-mobile) and only support 7mbps or 14mbps.

It could be the reason why it shows up as 3g instead of 4G (which really is a bs term by the way).
[T-Mobile Samsung Galaxy S II SGH-T989] -Mr. X-:
It does have 850/1900 HSPA bands as thats what telus uses. If you imported a Tmoble device, the radio rom they have does not include the 850/1900.

Flash the telus radio and you should be in business.

It was meant to be a quote from some one else, but then i miss quoted and am also too lazy to go back and find who i quoted in the few pages, I agree with you, just sick and lazy today is all. I should probably go fix it though to prevent confusion.
[T-Mobile Samsung Galaxy S II SGH-T989] marcopolo1:
so i need to flash Telus radio that uses HSPA+ 850/1900 .. where i can find those?

if i flash telus modem, can i revert it ?

yes you can flash back to the tmobile modem, you can get a clockwork mod flashable zip for the telus modem here http://xdaforums.com/showthread.php?t=1426001

please post your results and let me know if my theory is correct. I shouldn't say Tmobile doesn't have 850/1900 i should say that they may not have HSPA+ enabled on it.

The tech world is extremely, extremely sad if this is what it's coming to.

Dual Cell refers to the DUAL SPECTRUM CARRIERS used to achieve 42Mbps HSPA+ (2 5MHz 21Mbps HSPA carriers bonded together=42Mbps peak speed)..

Release 8 LTE has nothing do with Release 8 HSPA - they are different technologies that require different types of modems! One is OFDM/MIMO and the other uses QAM Modulation.

Release 8 HSPA:

http://www.3gpp.org/HSPA

Where is the LTE backwards compatibility that you completely made up mentioned anywhere on this page for Release 8 HSPA which is what our phones support and ONLY the GS2 supports. Go read the press releases for our modem. No where is LTE capability mentioned, nor is the modem used in the Skyrocket because *IT DOES NOT SUPPORT LTE*
