just used jpegsnoop on both pictures containing the phone label

both showed up as edited /processed

id understand if the secondone was processed because of the blurred imei

the first one had nothing "blurred"

upon further investigation

because all stickers are like that,eh?
[T-Mobile Samsung Galaxy S II SGH-T989] AllGamer:
i was dubious of that as well

because my sticker looks nothing like that
[T-Mobile Samsung Galaxy S II SGH-T989] AznDud333:
try jpegsnoop on the picture where imei isnt blurred out

jpegsnoop also reports that to be edited/processed

as mr.x has mentioned, if our modem was indeed the MDM8x00, the modem for MDM9x00 wouldnt work for our phone

but it seems that the Skyrocket modem is working fine for our phone, so Mr. X's suggestion seems to stand

here is the prove i flash Telus Modem on my T-MO galaxy S II and did not brick my phone
[T-Mobile Samsung Galaxy S II SGH-T989] marcopolo1:
I posted this picture to prove that flashing the modem mr x upload will not break/ brink your phone..

someone said that those will or mr x was looking for guinea pigs to test the modem without consequences of bricking the phone.. but that is not true ..

i can't test LTE because there is not LTE.. i wan to test if changing the modem of the T989 i can switch HSPA+ bands. from AWS to 850/1900.

i know this phone is penta band but only on HSDPA.. testing here HSPA+
[T-Mobile Samsung Galaxy S II SGH-T989] 513263337:
OK come on!! Someone with Rogers or AT&T LTE plan & SIM card please test it.
[T-Mobile Samsung Galaxy S II SGH-T989] y2whisper:
So again...this thread has unveiled some useful information.

for me i found out the rogers version does have support for dual cell HSPA+ with the appropriate modem from telus.

I can also get 3g on an AWS network with the tmobile radio.

We can basically take this to any GSM network we want.

The missing piece is LTE. You have put evidence that it doesn't, Mr. X has evidence that it might. Bottom line it won't brick our devices so hey why not try and prove whoever right?

Personally I don't have any more stake in this but this thread has provided a ton for me.

side note. confirmed mr x. there isn't any LTE functionality in the Telus modem you select it and nothing happens. Hopefully Telus will update the radio when they launch LTE.

look forward to seeing your finding whatever they may be. (sometimes the fun is in trying)
[T-Mobile Samsung Galaxy S II SGH-T989] quest4fire:
I am curious to see how this turns out. Hopefully someone can test soon. What's driving my train of thought is that ATT and TMO were going to merge, it would make sense that Samsung built the phone to be compatible with both networks (HSPA+ and LTE) to be on the safe side.
[T-Mobile Samsung Galaxy S II SGH-T989] Longcat14:
If, say the modems WERE different, then why would I be able to flash T989 radios without my phone going crazy, and service works fine.

If they were 2 different radios, the service would crap out on me, and I'd get the circle with a line through it.

I'm more then willing to meet someone near me to test this, but I don't know if anyone is near me.
[T-Mobile Samsung Galaxy S II SGH-T989] joking:
I don't think Mr. X disappear but he just ignore you and spend his valuable time to developed something useful for our device.

The title of this thread clearly stated that this is for R&D. You came in and stated that it will brick people phone and you have been proven wrong. You post some picture which also been debunk.

This thread and even this forum is about development. When a user come here to flash a custom ROM or other mod, they already take the risk of bricking their phone. If this work great, if it's not we have nothing to lose.

So stop littering this thread.
[T-Mobile Samsung Galaxy S II SGH-T989] AznDud333:
ok

let me ask you a few questions

do you have this phone? did you flash skyrocket/rogers modem on it? did you test it on a lte network? can you post a video?

kthnx.
[T-Mobile Samsung Galaxy S II SGH-T989] joking:
I think he's brick.

Anyway I'm done wasting my time with him.
[T-Mobile Samsung Galaxy S II SGH-T989] Longcat14:
Look, I'll give you the benefit of the doubt, and trust you.

But there's no reason to not try, if it doesn't work, it doesn't. No harm no foul, now am I right?
[T-Mobile Samsung Galaxy S II SGH-T989] marcopolo1:
hey guys i created this thread to investigate, ad rumors, you know, play with the phone.. making them better.. not to fight ..

everyone can do anything with the phone.. we are the only one responsible if we brick them.. however i dont like when other people tell me what to do , or not to do..

just .. KEEP TESTING, PLAYING AND MAKING OUR SAMSUNG GALAXY S II HSPA + BETTER .... AND SOON.. LTE CAPABLE !!
[T-Mobile Samsung Galaxy S II SGH-T989] staticfloat:
I know I have zero credibility as I have never posted before....... but seriously, take your phone apart and just look at it. Nothing else will convince you.

The chip is on the backside of the motherboard, there are only a few cable connectors you have to take off, be careful and you'll be fine. If you're not comfortable doing it....... wait until someone tries it.
[T-Mobile Samsung Galaxy S II SGH-T989] AznDud333:
i agree, which is why i will start ignoring this guy..
[T-Mobile Samsung Galaxy S II SGH-T989] Longcat14:
Honestly, if I felt comfortable enough, I'd tear apart my SR and see the modem on it, but yeah.. I'm not lol.

Unless someone wants to help? :D
[T-Mobile Samsung Galaxy S II SGH-T989] AllGamer:
+1

ahh! this is exactly what i wanted to hear

so it's then possible to flash the AWS radio to the LTE version of the phone and have it work as a normal HSPA+ 4G on Tmo/Wind/Mobi/Videotron

that's awesome!

[T-Mobile Samsung Galaxy S II SGH-T989] nodrogkam:
Perhaps I have misunderstood your post.

I easily get unlock codes for free from T-Mobile for T-Mobile branded devices - regardless of whether I bought them with a discount or outright or from a third party.

I am however still on a contract with T-Mobile but I bought my gsii outright for retail price. The unlock code was given to me by customer service free of charge.

Maybe you should try again...
[T-Mobile Samsung Galaxy S II SGH-T989] RuizGT:
I'd recommend calling back and speaking with another rep definitely, longcat, I usually have to call back every once in a while at work if a rep gives me the wrong info. Some know what they're talking about, some are just lazy and want to tell you they can't do it just to get you off the phone.
[T-Mobile Samsung Galaxy S II SGH-T989] bobbymokie:
hey if you bought from a tmob store or authorized dealer it doesnt matter if it was on contract or not they owe you an unlock code for it. only exception is if you got it on installments, they you have to pay it off first
[T-Mobile Samsung Galaxy S II SGH-T989] nodrogkam:
that's exactly right.

perhaps people with this issue are asking the CSRs the wrong question.

Make sure to tell them that you're looking to travel outside of the USA - you can make up a country, and that you wish to be able to use a local simcard while you're traveling abroad.

On a side note - I also have t-mobile prepaid from YEARS ago, and even they still give me unlock codes - I only pay them $10 year cause i'm a gold rewards member.

Anyways, try again - it does NOT hurt.
[T-Mobile Samsung Galaxy S II SGH-T989] chiensibut:

This sounds too interesting to pass up. I am willing to sign up for an at&t lte 2 year but I was wondering if they would sell me a 2 to 5 gig plan and similar without hardware.

It wouldn't be wasted money for me because I could tether my laptop with my lte for work and school and just use my mobile plan for browsing.

[T-Mobile Samsung Galaxy S II SGH-T989] scribbles92:
I've done it twice before and it's just that easy with T-Mobile. No runaround, no pointing you to Samsung or any other manufacturer. You have to be under contract for more than 90 days (other carriers may be longer) and in good standing (no past due bills or charges) and they will email it to you.

For those of you unable to get one through at&t I'm sorry, that's all of them and their bull****. Don't blame Samsung. They are supposed to by law grant you an unlock code. It's law in the UK and in the U.S. as well. AT&T likes to play dumb and not allow this. Another reason why I'm so glad the merger didn't happen. I hate them so, so much...

Phone: T989 running Juggernaut 4.1

Carrier: AT&T non-LTE data plan

Location: Oakland (supposedly with LTE now)

Baseband: Flashed all three zips from this thread http://xdaforums.com/showthread.php?t=1384865

Results: No signal (circle with line through)

I can't even get a signal. Any ideas? I tried changing the preference in the *#2263# menu with the Rogers radio, but still no signal. Searching for a network goes on forever with Rogers radio. With AT&T radio, it gives me an error after a minute or goes on forever. AT&T 3g works when I flash back the T-Mobile radio.

I'm thinking of flashing a Skyrocket rom. Any suggestions on which would be the best for our testing purposes?
[T-Mobile Samsung Galaxy S II SGH-T989] marcopolo1:
I flashed telus radio modem and works fine.
[T-Mobile Samsung Galaxy S II SGH-T989] Sheolrock:
Your sim	card/account has to be LTE enabled in order to connect to data and in fact...my skyrocket received no data at all when I plugged the sim card from my infuse into it until my account was upgraded to LTE; no Edge, no 3G, no HSPA+. I can confirm LTE is available in Oakland. I'm in Oakland right now with LTE connection.

Edit: The true test would be for you to flash one of those modems and test it with an LTE enabled sim. I'd be willing to volunteer my sim seeing as how you are in Oakland as well.

So Sheolrock and I tried his LTE SIM in my phone. With the Juggernaut Rom we were able to get a signal and data, but no LTE. I tried flashing some Skyrocket roms (Skyrocketeer and Bonestock) and the conversion zip, but we keep getting a bootloop when his SIM was in. When I put my SIM in, it stayed stable, but wouldn't get a signal. Take from it what you can, cause we're clueless.

Could you please describe more thoroughly what device you had, which modem you flashed, which SIM card you plugged in (you said his SIM and your SIM etc but I don't really know which SIM is which carrier) and what result?

This is breaking my heart...
[T-Mobile Samsung Galaxy S II SGH-T989] Sheolrock:
I have an at&t sgs2 skyrocket and an at&t LTE sim to go with it. Dascientist has the Tmobile sgs2. Initially he was on juggernaut (4.1 I think). When the Tmobile sgs2 on juggernaut had the kj2 at&t modem flashed it got no signal of any sort using the sim that was not LTE enabled. When we plugged my LTE enabled sim in with this same configuration we got 3g and hspa testing at about 5-6 mbps while my phone was getting about 35 mbps (on LTE of course) in the same location.

So then we flashed a skyrocket ROM (skyrocketeer) with the conversion zip and reflashed each of the skyrocket modems (kj2, kj7, kk1) to test them all. The phone would boot up normally and would have cell tower signal but no data. After about 15-20 seconds the phone would reboot without ever displaying a data connection and do it all again. We then flashed another skyrocket ROM (bonestocketeer) and tried all these modems again with the same exact result.

At this point we plugged the original non LTE enabled sim back in still running a skyrocket ROM and modem. We got neither cell tower signal nor data BUT the phone would no longer reboot continuously.

I would not claim to have enough knowledge to declare LTE on the Tmobile sgs2 impossible...but we were not successful in our tests.

I have the telus s2x and it comes with 850/1700/1900/2100 HSPA and quadband edge. So with the Telus radio you can have AWS and 850/1900 HSPA at the same time (idk if it's the same thing with the T-mobile radio or not).

If only I had known about Skyrocket supporting AWS earlier.. I like the look of the Rogers Skyrocket better than ours and would have taken that over this. Oh well, we still got an amazing phone :p

Hate to say it but heygrl is correct.

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."
