[Q] galaxy s2 i9100 radio on galaxy s2 skyrocket - AT&T Samsung Galaxy S II Skyrocket SGH-I727

I understand how to flash radios and roms, not so much of a noob. but maybe this is a noob question. I have brought a att locked phone, I unlocked it. I live in the dominican republic and i have a plan(contract) with the orange phone company here. I only get 2g speeds(edge) not even 3g because skyrocket uses the 850 mhz band and my phone company uses 900. I wanted to flash the i9100 radio/modem hopefully to be able to get 3g here. if someone have insight on my situation please let me know

I'm not really sure, but I am 100% positive you cannot flash any other radio except the skyrocket, t989, and note(be careful) radios, the skyrocket has different internals

And the blaze 4g I believe.

thats why i asked, able to flash galaxys note radio wondering if the s2 i9100 could be flashed too. really need to get 3g speeds here and i love my skyrocket phone to much dont really want to sell it to buy another one

someone please help!

different internals, so no it just wouldnt work. the note they meant was the att note which also has an s3 not the international note which has an exynos like the i9100

im just wondering, why did u get a skyrocket to unlock instead of just getting the international unlocked sgs2 i9100?

Definitely do not flash an i9100 radio on the skyrocket.
You might want to try flashing a Rogers based rom and/or flashing the Rogers radio found here: http://forum.xda-developers.com/showthread.php?t=1384865
Most of the Skyrocket radios are RAT locked, meaning you can't change it by dialing *#2263#. The Rogers one should work for you I think (but someone please correct me if I'm wrong... )

I brought the phone on craigslist and i read about the power and beauty of the phone and i fell in love with it, didnt forsee this problem. thought the minute i unlocked it i would get the data speeds minus the lte. i was wrong

flash the blaze 4G radio, i swear that uses the 900 frequency, or any other t989 radio for that matter. Most of those are RAT unlocked as well. Don't stress too much, the skyrocket has a penta-band radio that would do any world/touring phone proud

2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 850 / 1700 / 1900 / 2100
Those are the frequencies that are used for the sblaze and the t989. seems like i have no luck because i need it 900 for 3g. guess 2g is going to eventually kill me one day. thanks everyone who contributed to my search for answers. I appreciate it'

20 dollars paypall to anyone who can help me find a working solution

30 dollars?

Change your service!
come ooon! Orange LIE about supously 3g service and the maximum speed in orange is less 1 mega :-O I did test in all Dominican Republic and I think you are waste your time with that! I have a Skyrocket in Claro and I have a Blackberry pre paid service and I have 4 to 5 megas of speed! that rreally good! my modem RUXUMA 7 and my rom is Embryo 6.4

Help - want to buy Captivate for UK?

Hi everyone. I’m currently living in the UK and I’m interested in the Samsung Galaxy S (i9000). Unlike in the USA, there’s only one variant and its quite expensive. Much cheaper in the USA! So I’ve been looking at the Samsung Captivate, AT&T’s Galaxy S variant.
Network
Samsung Galaxy S –
2G Network
GSM 850 / 900 / 1800 / 1900
3G Network
HSDPA 900 / 1900 / 2100
Samsung Captivate –
2G Network
GSM 850 / 900 / 1800 / 1900
3G Network
HSDPA 850 / 1900 / 2100
2G is exactly same band, but 3G is only 50MHz difference.
Will both 2G and 3G networks work fully in the UK?
Software
Am I correct in thinking I can remove the AT&T bloatware by flashing a custom ROM?
Can someone please suggest a good, fast lag-free 2.2 Froyo ROM?
Android Market
Am I correct in thinking I can use Market Access to change US market to UK?
Thanks for help in advance
you are confused on the 3G bands.... "only 50Mhz difference" statement is meaningless - if bands are not exact, then it won't work - period.
Having said that, the captivate will work in the UK - the 1900/2100 bands are 3G in US (ATT) and UK. You will get 2G and 3G.

What about the android market? Can I change it to UK using "Market Access" app?
Also, seeing as for 3G the first band is different (900 vs 850) will it have any affect on my 3G network connection?
The Captivate is a World Phone, meaning it will work around the world. If one 3G band doesn't work, you have 2 others, which you have already been told will work just fine

Yes, you should be able to use the Market Access app, but it takes a carrier code, not a country code. Using the phone with another SIM may set it automatically.
As for bands - you will probably find some areas where 3G is offered on a band you don't have - it is possible, but shouldn't happen any more often then if you had 900 on the phone. I took my iPhone all over EU - it was an ATT iPhone, and it worked fine with 3G. The Captivate should do just as well.
Thanks for the help guys
Not only can you flash custom ROMs, but the SetiroN kernel lets you flash regular Galaxy S ROMs onto the Captivate. If you look in the development forum here, you'll see that there's basically only one native Captivate custom ROM (Cognition); the rest are all Captivate-flavored Galaxy S adaptations using SetiroN (or its predecessor).

Our phone... is amazing.

I was stalking the T-Mo SGSII forums when I saw this..
http://forum.xda-developers.com/showthread.php?t=1417095
According to that, their phone has an LTE radio... which means even the radios between our phones are the same..
I did some research, and I learned that our Skyrocket is a pentaband phone.
HSPA+: 850, 900, 1700, 1900, 2100.
And having 6 LTE bands....
This is probably the best radio made by Qualcomm... ever.
But I thought the Exynos chip could not support LTE? Only the Snapdragon..
Both phones have snapdragon processors.

Wait.. whaaa? This is the first I've heard of this, but doing a check on phonearena, it looks like it has supports the 1700 band. Has anyone tried this phone on T-Mo?
Lately, I've been thinking of selling the phone and going T-Mo b/c their plans are so cheap.

This is the info I got from phonearena. Most gsm bands are the same from the Tmobile sgs2 and the a&t skyrocket.does this mean if I unlocked my skyrocket I could use t mobile pre paid internet and voice plans.I currently have a AT&T 50$ unlimited pay as you go, but can't get Web (internet because it's a smartphone) has anyone tried using there skyrocket on Tmobile hspa+ network?

Yes, our T-Mobile Galaxy S II people are trying to see if we can activate the LTE radio on our device by flashing your modem.
If you are interested you can try flashing our modem to see if your phone can use AWS (1700) on T-Mobile / Mobilicity / Wind.
Our modem is here: http://rootzwiki.com/topic/11883-odin-tmo-sgsii-modem-collection-team-kang12142011/
Note that after flashing our modem your phone will lose LTE. After you are done testing you can flash back your own modem which is here: http://forum.xda-developers.com/showthread.php?t=1384865

Someone on the original thread was able to flash a T-Mobile radio and get Wind 3g signal (which is AWS) so looks like the radios are the same... anyone else want to try flashing a T-Mobile radio to see if T-Mobile 3g/4g (idk what they call it ) or Wind Home zone/Mobilicity 3G (non-roaming) works?
I've been following both threads and it sounds like Telus/TMobile radios does work on our LTE device? I'm travelling to Orlando later this month and would love to use their 3g data prepaid plan instead of 2g data.
It sounds like all I have to do is flash the Telus radio before I leave and I should be able to use Tmobile's 3g network? Then when I get back, flash it back to the Rogers radio so I get LTE back? Does that sound right? Thanks!

It is indeed amazing. Flashed juggernaught and the T-Mobile radio. Getting 4g with no issues.

I've been doing some research... the MDM9200 (modem in the Skyrocket) has LTE (Band 17 and Band 4, I also found a device with Band 13 but not sure if it's included in the SkyRocket) and it has HSPA+ Release 8, which means DC-HSPA. This means the by flashing a Telus/T-Mobile radio, you could theoretically get the same speeds that the SGH-T989(D) gets. I also found an MDM9200 device that states it has HSPA+ 850/900/1700/1900/2100 so that means that this modem can handle a LOT of bands, it just depends on which radio you flash.
Alright so I got my Skyrocket and flashed the latest T-Mobile Modem. AWS HSPA+ works perfectly fine, voice quality is actually much better than it was on my Hercules. I restored my setup from my Hercules and just changed the TDJ kernel to Da_G (waiting for them to make a kernel for the Skyrocket).
So that settles that once and for all. This phone has HSPA+ 850/1700/1900/2100 (and it's DC-HSPA so the max 42mbps is enabled if you flash a T-Mobile/Telus radio). It also has LTE 1700/700 with the 700 being band 17. I'm really hoping Wind gets the lower B or C block so I won't have to switch phones if/when they deploy LTE.
The Skyrocket has everything the Hercules has, with just MDM9200 over the MDM8200 in the Hercules. If you google online, the MDM9200 is like the MDM8200 just with LTE on top.
Once again, this phone is in fact amazing lol
Guess I should change my username if i could lol "SGS2LTE"

T-mobile 4G LTE on Unlocked i727 when available?

Ok well i know that it is possible to get T-Mo's "4g" HSPA+ on this device. However, i have not found a clear answer as to when t mobiles 46 lte launches, will an unlocked at&t i727 be able to work on this t-mobile 4g lte. I am stuck between whether i should buy the t989 or an unlocked i727 and use either one on t mobile and this may affect my decison.
Thanks.
I never heard before about "T Mobile LTE !!!" ... T mobile is using HSPA 42 in its best markets ... If you're in a good coverage area from T mobile or you only want to use it , I would say just buy the T mobile S2 and be done with it ... At&t SR even if unlocked and T mobile radio installed in it would not have the full speed for T mobile or aka 4G (may get 3 or 4 mbps DL max) ........
This thread is relevant to my interests. T-mobile LTE will be Band 4, so does that mean the i727 won't work? Or does it have that band and they just aren't advertised? ATT does have some Band 4 holdings, so it's reasonable that they would want the i727 to work on LTE in those areas too.
If you get into Service Mode (*#2263#) and look at LTE bands, it's shown there. Don't know if it means that the phone is able to work with it, but might be.

FYI - This only works on Touchwiz ROMs.
if and when tmobile launches lte a t989 won't be able to use it anyway, no lte radio, the fastest that phone will ever achieve is h+ (fake 4g) speeds.
an unlocked skyrocket will allow lte usage, on bands 700 and 1700, so with the correct radio (i757m modem from bell) u SHOULD be able to access it

an unlocked skyrocket MAY allow lte usage, depending on the lte band they use. It'll probably be 1700 AWS though, which is an lte band I don't believe the skyrocket supports, only 700.
So basically, neither. But if ur a gambling man, at least with the skyrocket u stand a chance

I thought the reason AT&T included the 1700 AWS band was b/c they were planning on turning that spectrum into LTE if the acquisition was successful. If so, wouldn't that mean that the 1700 band on the Skyrocket would support LTE Band 4?

was under the impression 1700 for skyrocket was only for hspa, read it somewhere, I stand corrected
Just saw this very recently:

If I'm not mistaken, the Note has the exact same radio setup as the Skyrocket (AWS and 700Mhz LTE). So, it's looking promising for our phones to work on LTE, too.
Just wanted to bump this to see if anyone got the unlocked i727 to successfully lock onto the T-mobile LTE network. I believe I read somewhere that someone had done it successfully but wanted to confirm since T-mobile has refarmed most areas by this time.

Yes..I'm sorry...I didn't know that at the time I replied..They have LTE and ironically we skyrocket owners can access it and the T-Mobile s2 owners are left being lol...

For those who unlocked & went to TMobile

I do not know if this is allowed and if it is not sorry but it is not a best of thread. I have been having trouble getting good speeds since the switch and have tried numerous combinations but get crappy speeds like .11 mbs down and .12 up
I was wondering what works for you and what speeds are you getting.
Like I said this is by no means a best of thread I just thought this would help others like me who are having trouble getting good speeds on our phones.
Any downloads to the radios not listed in the radios thread would be appreciated.
And if this thread is off limits I am sorry. Just thought I would help us newbies out!!!!!!
Thank you

What gives me a little pause here is that those settings and radio combinations will yield different results based on where you are located. Do you know anyone in your area with an HSPA+ phone who can run speed tests to compare your speeds against? It could just be that you're in an area with bad backhaul.
two important bits of info are missing what network type is your phone connected with (g e 3g h h+), and what radio are you using?

Baseband version is unknown
A good first step is to find some friend with a good t mobile hasp+ phone (like galaxy s2 T-Mobile or galaxy nexus for instance) ...See what speeds they're getting on T-Mobile data...If they're not getting good speeds on their phones, you'll never get good speeds obviously...Remember you're using a phone which was made to be used with AT&T....And from my observation most of those who use the SR with T-Mobile they get similar issues like the ones you're describing , t-mobile switched to the 1900mhz spectrum in some areas that would probably help a little, but obviously that's not something that you can do anything about...
If you really need tmobile service, it's best to trade your SR with a tmobile galaxy s2 , at least that I would do if I was in your situation,I don't like buggy phones or services...

It's a long thread but covers this issue pretty well. As far as I can tell there is no hardware-based reason a Skyrocket can't work on Tmobile as well as a dedicated tmobile S2.
I have been using a skyrocket on tmobile for a few months. I couldn't get better than 2G speed until I flashed a new radio and twiddled the apn settings. I get pretty consistent 4G now.
This is what I get using T769UVLH5 radio from this thread http://forum.xda-developers.com/showthread.php?t=1895400
Be sure to thank him:good:
I know you're getting different answers here but if you took an at & t skyrocket it means you have bands 850/1900Mhz for 3g ( don't even think about 4g lte at this point) while tmobl works on 900/1700/2100 3g bands. This means your phone is physically not capable of locking on those bands because it doesn't have them. All it's probably doing is sticking to the old EDGE network since it is a quad band edge.

I do not believe that is the case. The skyrocket radio software limits the available bands. Loading a tmobile radio enables the required frequencies.
i727 freq's:

From what I've gathered the skyrocket has the same radios as the Hercules, it just has the added lte hardware. I am on 4.2.2 slim using the le1 radio. Still get random no signal dropouts but not as bad as the others. Think my ril and csc files are wrong so it looks like I have to flash a stock ROM to get them back. Anyone using a stock Hercules ROM?

I don't think our channel can do dual channel h+ where the T989 can.
for the others our phone has a penta-band radio it is physically cappable of talking to t-mobile on it's 3g,h,h+ networks just not with the att or rogers radios.

I want to figure this out once and for all.
What services does this phone support on the 850 MHz band?
The big question is whether UMTS/HSPA works. NYC area has amazing 850 band coverage on AT&T.
If I were to put a prepaid AT&T SIM in my phone, set my phone to only operate on the 850 MHz band, and set the proper APNs (necessary for 3G?); would I be able to get data beyond EDGE?
Only one way to find out...
There's no mystery to it if you read through the [GUIDE] Set up Verizon Galaxy S3 as World GSM Phone (confirmed working) thread and the [BOUNTY] ($205 so far) Enable HSPA+ on 1900 MHz / 1700MHz for VZW Galaxy S3 i535 threads completely....
With the radio software verizon has on the phone, the galaxy s3 is quad band GSM (850/900/1800/1900) and single band WCDMA (2100).
We don't know if it has the hardware for WCDMA 850/900/1900 and until now, nobody has successfully flashed a different radio due to the bootloader lock. Keep an eye on the "enable WCDMA 1700/1900" thread for updates.
And just to answer another question that you might have, when my S3 was rooted and set up to work in Germany, I tried both T-Mobile and AT&T sim cards here in town. The problem with the S3 is that even if you try to select a different WCDMA band in the field test menu, the radio firmware will not allow you to change it from 2100. So in an area with T-Mobile PCS (1900) and AT&T PCS/CELLULAR (1900/850) WCDMA, each test I tried only ran on EDGE.

Wow... That really sucks.
So, there's literally no way to get 3G outside of Verizon aside from MetroPCS EVDO?

The first step is to experiment with different radio files, as one user in the 1700/1900 thread wants to do, but we need to get the secure-boot/bootloader unlocked so those files can be written.
Phones like the Rezound had the hardware for Quad-band WCDMA (3g), but took a radio file flash to make it work. The reason there is a bounty is because we -think- the Verizon S3 has the hardware, it will just take some work to get the software on the phone to talk to that hardware.
I know. I've been following the thread.
Was a little unsure of the details regarding frequencies.
As far as I understand, they're at a dead end. They need JTAG/UART to continue without worrying about bricks.

Yeah, and sadly, I lack the skills and the bounty probably isn't enough to attract a dev with JTAG and a phone to fiddle with to solve our issue
Verizon cdma is ran by nortel dual urban base stations the frequencies are 810-910 and 1840-2000mhz. The LTE is 690-760mhz 1x means that your on 850. 3g means your on 1900 or 850 depending on how far away from the site you are, and 4g means your on LTE. The LTE base station is ericsson but speeds will vary depending on whether or not the site is on fiber or T1 transport. Normally they keep the pre pay customers on the nortel dual urban... Oh by the way we are starting to decommission the lucent cdma on metro pcs sites and convert them to t-mobile GSM but luckily metro uses ericsson for LTE too so there's hope.
