SGSII (I9100) available (FOR PURCHASE)in China to use in the US??? - Galaxy S II Q&A, Help & Troubleshooting

Hello wise XDA forum members.
I have 4 questions, and I am trying to make them as concise as possible to ellicit a response.. I know what its like to see posts of drivel.. I'm deperately trying to avoid that, myself.
QUESTION 1: I currently own an SGS and I am leaving for China on the 21st.. I'll be there through the 5th of June and I was wondering if there is anywhere I could look at and pick up an SGS2 in person while there(China)?
QUESTION 2: On the off chance that there is... (and even if there isn't) From what I've read the SGS2 works on the two bands that ATT supports for their 3g/4g service, but there is NO support for TMO "4g"(fake) connections, correct?
Question 3: I would be relegated to only "edge" speeds if I stayed with TMO, I'm assuming (as per question 2 above), but other than that would all functions of the phone work (albeit with slower data)?
Question 4: I am considering a switch to ATT but with the merger coming soon(???) anyway would it be shooting myself in the foot to switch while I have a contract and pay the fee when I will likely have access to ATT towers relatively (again... who knows when) soon?
I've read the FAQ's, etc, so I hope I'm not stepping on any toes or across any lines in asking this.
Thank you for your help.

#3 - I've had experience with that on a different phone. It would work, but I wouldn't recommend it. EDGE is motherf*cking slow. Google Maps is useless because once the map loads, you've already moved several yards and would need to load a new map. Audio/Video streaming is impossible (buffer, play 5 seconds, buffer). Web pages will take 10-30 seconds to load, longer for sites with a ton of pictures/addons.
#4 - The Tmo/ATT merger will finalize in 1-2 years once the Feds approve it (will probably take several months as well). Once that happens, ATT will still need several months to a year to convert t-mo's AWS for its LTE use. So basically, Tmo AWS phones will be unusable (at that band anyway, will still work on other bands) in 2-3 years. Most likely you would've replaced your SGS2 by then. Plus, ATT will replace your handset with a comparable one (no cheap androids/dumbphones) once you sign over to them.

T-Mo Users - Would you run an Unlocked ATT Note or the official T-Mobile hanset?

Good Morning!
I'm in the midst of trying to decide the best course to follow - I use T-Mobile prepaid for the data / messaging plans since I rarely talk on the phone; with the official T-Mobile branded handset coming out next week I'm stuck deciding whether to buy an unlocked ATT Galaxy Note or wait it out for the T-Mobile one to be available. I don't plan to sign any contracts so I'll have to pay outright (street price or store depending)
I know the major difference between the ATT Note and TMO version is the fact the ATT one has the 21 mbps hspa+ antennas versus the TMO one having the full fledged 45mbps antennas
while 5mb d/l is nothing to scoff at (ample for my use) I suppose more is better - but is it worth owning a 'more flexible' hanset that can run tmo/att/lte versus a tmo only handset?
thanks for your help in deciding!
Sorry Mods, as you can see I read more than I post - this can move to the Q&A forum if you see fit
wait for the tmobile one
you wont need to flash no modem to get 3G/4G service.
You also won't have to worry about charging the ATT version every 3 hours and worry about the phone heating up. I had the ATT one and I hated it for those two reasons.

Many members have had troubles with flashing the t-mobile modem on the att note.
I had t-mobile data plans for many years and liked the speed and no contract.
I would wait one week for sure.

the TMO version won't be any different, if you had to charge the ATT ver. every 3 hrs, which is absurd, mine last me most of the day on one charge, you will also have to do the same thing with the TMO ver. since the specs are the same and so is the battery.

Don't mind me, but after 4 months and avery ROM available, this hasn't happened to me. At worst I get 8 hours, but that's not stop phone, text, ebook, facebook, nand-backup ROM flashing and restore.
OK, the question: As I said I've been on the Note with tmobile for 4 months. data is poor....not horrible, but poor - but I'm at home on wifi most o the time, so it shouldn't bother me. Shouldn't is the operative word - thinks like this drive me to distraction.
So.....if I find the note 2 is being released, I'm going to hope t-mobile will offer it. Don't get too excited, it was something like 8 months between S, S2 & S3, so sometime in Q2 '13 seems about right.
Of course I'd have to take it on a leap of faith on after the announcement of the note 2 that T-Mo might get it and 8 months is a long time, assuming I'm anywhere near right.
Oh, my druthers: If everything were equal, I'd want the T-Mo version (cost wise).

Not only that, they run on different radio frequencies.

The Note is pentaband, so techincally both the ATT and Tmo models are capable of running on each others' networks (provided you flash the correct modem).
The main reason some folks will probably stick with the ATT Note (myself included) is because of grandfathered data plans. For example, I still have the T-Zones data plan which I've had since the voicestream days...and basically get full unlimited internet (3G speeds) at under $10 a month. Granted, the speeds are probably not as fast as the normal $20-$30 plans, it suits my purposes just fine.
If you have one of the more recent standard Tmo plans, then I suggest going for the Tmo note, as it'll basically work right out of the box for you. I'm sticking with my ATT Note and hopefully when the Tmo radio gets leaked here it'll fix the terrible upload speeds and bad voice connection I experience now. *fingers crossed*
I've been spared from the terrible voice problems so many have experienced, just typical data slow downs.
Of course one could buy from cl or eBay, which would void the warranty, then again I'all be doing that on my own.
thanks all for the advice and tips - i did lots of reading as well into handling tmo radios etc to get the ATT version to run TMO properly
I did buy a ATT Note yesterday (the price was right) and I figured why not try it out right?
the Note is already running the S3 Rom with a few tweaks iirc, the seller had a local service mod it a few weeks back
without flashing the modem, just inputting the network unlock code (cellunlocker had it in 2hrs) a speedtest on 4G showed only ~150k d/l speed and after flashing the icsblaze.zip modem I had ~400k d/l speeds, so that's a little imrovement...
If i can get a solid 2mb d/l I'll be fine since I'm around wifi pretty often, but for the times I'm not...well...
I'm in the process of dl'ing Flapjaxx's ICS build and have an assortment of ICS radios (better check if they are in fact the ICS flavors or not) to try out
Thanks again XDA! what an awesome community
I've been using ATT note on Tmo for the same reason (grandfather in tzone). I am just waiting for a solid radio coming from Tmo Note.
I'll most likely be using an unlocked one. My brother got one for free (I think it was a friends) and we unlocked it. When the T-Mo version come out he'll upgrade and I will too from my G2. I use Wi-Fi when I'm at home or anywhere that has it for that matter so I don't think the slow(er) data speeds will bother me that much. As long as calls are okay then I'm good.
T-Mobile Note also will work on AT&T HSPA+ Network.

I would wait for the tmobile version. My unlocked Note with the tmobile radio had spotty connection. One minute, I'm getting 2MB, the next serveral hours, i'm getting 112kb or it does not work at all.
Also when 4GB is running, the backside of the phone (below the camera) heats up a lot. Almost to a point I had to put the note down and let it cool off by turning off the network data. So it's working really hard to maintain 4GB and eating up the battery. It doesn't happen on wifi.
the only reason why I would want the At&t version is because of the white note and lower price.
I'm fine using my at&t version. If it's the same hardware I don't see a big reason to switch.

Only reason I would get the tmo note would be for the wifi calling feature.. Then again it might be possible to flash tmo note stock ROM on unlocked att now and have the wifi calling feature, guess we will find out the 8th or soon after

[Q] Should I leave Verizon?

I like Verizon, the coverage is great but sometimes I wonder if the grass is greener. I like to try all the different phones out there and T-Mobile and AT&T have the most open networks for switching out phones. I think T-Mobile is not going to work because the coverage is just not there. I used to be an At&T customer and only left really for Android (Original Droid). Now that Android is spread to al the carriers I wonder if I might like AT&T better just because I can switch out phones so much easier. Anyone have any input, maybe someone that has switched from Verizon to AT&T?

I'd love to provide some input as a user who has been a Verizon customer for a few years and is switching to AT&T. I previously used the Galaxy Nexus on Verizon and then switched to the iPhone 5 last year. I am still on an unlimited data plan. However, I have grown increasingly frustrated at Verizon because of their lack of phone variety, slow updates, locked bootloaders, Verizon customizations (persistent WIFI notifications, for example), etc.
So I bought an HTC One on AT&T the other day and am currently evaluating it. Right now I still have my Verizon iPhone 5 with unlimited data. But I also have the HTC One with the 5GB data plan (I have a 25% business discount).
SO is the grass greener? Yes and No. Here are some of my thoughts:
- Verizon has better overall coverage, but AT&T is faster. In my area, LTE on AT&T just went live, and while speeds are comparable, AT&T has better penetration already into the buildings I've been in. In my workplace, for example, I can get 4G LTE on AT&T but only 3G on Verizon unless I am close to the windows. It's nice having HSPA+ as a drop down from LTE as opposed to Verizon's very slow 3G network IMO. Can't deny Verizon's coverage is second to none, but AT&T is good in my area so this is probably the primary consideration (how is AT&T in your main area you'll be in???)
- It would be very hard to give up my Unlimited Data plan on Verizon. It's nice not having to worry about data caps. However, in actual use, I rarely go over 3-4GB per month and only occasionally reach 5GB. I don't think 3GB would be enough as I'd be constantly worrying about going over, plus I'd have to workaround tethering. For now, I'm keeping my Verizon line until I am absolutely sure.
- Phones! GMS > CDMA if only for the flexibility the former has for phones. The floodgates are open on AT&T and T-Mobile, but Verizon takes longer to get phones, has less variety, and has complete control over them. I hate everything about what Verizon is doing, and it's clear they don't have geeks in mind that like to tinker and switch phones often. I change phones every 9-12 months usually, and AT&T is going to provide a better environment than Verizon for that. Not perfect, mind you. They still lock bootloaders, and have some draconian policies and practices, but by the nature of their GMS network, there is more flexibility.
- HTC One. I bought the One on AT&T before it was officially confirmed that Verizon would be getting it. So there is a part of me that thinks I should just return the AT&T version and wait for the Verizon version. However, I am not at all confident that Verizon won't screw it up or prevent HTC from allowing us to unlock the bootloader. And like I said, I'm just really tired of Verizon and their meddling. I may just end up keep both plans for a while, but right now I'm leaning towards keeping the AT&T version despite my unlimited data plan on Verizon.
Hope that helps.
Yes that was a great help. I am really torn because Verizon's coverage is so great. I know that ATT LTE went live here a little bit ago and I think the coverage is pretty good. Ironically I left ATT for the Droid on Verizon because of the lack of variety on ATT at the time. Thanks for your input.
honestly i would move to verizon right now if i could, in my area better coverage + better speeds

No problem. I know what you mean, I had AT&T a long time ago too and moved to Verizon when they changed their unlimited data policy. So it's ironic that I am now switching back. AT&T has done a good job of courting Android phone makers, and Verizon seems to be in the honeymoon phase of having the iPhone now. It's weird how things have flip-flopped! AT&T also has a few more consumer-friendly policies such as not forcing customers into a Share Everything data plan if you aren't already grandfathered in. They have rollover minutes (which I know isn't a big deal these day with people using voice less). And they have Mobile to ANY Mobile rather than just Mobile to Mobile, which is a small advantage I know.
But yeah, the primary consideration is how each carrier performs in your area. If both are good (like in my area), you have more options.

Yes, if one carrier has better coverage and speeds in your area, then it makes sense to use that carrier. In my area, Verizon's LTE has been around for almost two years now and I rarely get more than 10 Mbps downloads. Usually it hovers around 5-9 Mbps, which is not even much better than AT&T's HSPA+, let alone LTE. And when my phones on Verizon drop down to 3G, it feels like dialup speeds. So far, AT&T is noticeable better for speeds between my HTC One and iPhone 5.
But again, YMMV and this is just a subjective observation on my part. To the OP, you could always give AT&T a shot for 14 days and compare the networks. If it doesn't work out, you can cancel and just pay the restocking fee. Just use the new phone with a new number, so you don't have to port and cancel your old line yet.
It all depends on your location really. I live near philly and the service has actually been a bit better on att then verizon from when i had them a few years ago. The speeds are also better on att thanks to it not being cdma but rather hspa. Overall I would never go back to verizon due to their prices and slower speeds unless I moved somewhere where they had clearly better service than all other companies.
So what about dropped calls. I barely have any on Verizon, but I remember having them on AT&T. Does being on LTE fix that or is it still a problem?
I went from Verizon (been a customer for 10 years) to At&t recently because my wife's office only gets At&t reception and we wanted to be on a Mobile Share plan instead of having two separate accounts (saves us around 40 a month). I've had an At&t line over the years for work, so I know the coverage isn't NEARLY as good as Verizon, especially LTE coverage in my area (At&t just went live on a few towers in my neck of the woods), but the savings is worth the sacrifice at this time.
Plus, as you said, being able to use most GSM phones on the network is a HUGE plus. Being able to run the Google Edition on my HTC One will be fantastic and I don't think Verizon is going to make it easy to run that software. Plus, as another guy mentioned above, that persistent Wifi thing Verizon does is sooooooo annoying. Almost as bad as At&t putting their name in the notification bar of the GS3/GS4. At least it goes away after a few seconds on the HTC One.
I haven't had many dropped calls on At&t, but calls are not what I do the most of, so I'm a bad barometer for that. I know the wife drops a bunch but I just attributed it to being the Nexus 4 and not a tried and true, tested, At&t phone. She has a GS4 now, so we'll see if that improves.
Anyway, in short, I did it for strictly monetary reasons, but the plus sides of At&t are numerous so it's not as bad as thought it would be.

Thats what I am afraid of. My wife values the voice and I value the data. So dropped calls don't bother me as much, but it would really bother my wife. Especially coming from Verizon with very few dropped calls.
I dropped Verizon last year for AT&T and, despite the few rough patches everyone else has mentioned, it was worth it. No one can beat Verizon's LTE network coverage at this point, but I was so fed up with their other BS on updates and pretty scanty selection of phones that I did what you did and suspended my service for a month to see what happened. At first they weren't perfect, but I was fine with them and loved that I could go from a US SGS3 to an international One X without a hitch. Also, AT&T's coverage (both 3G and LTE) has expanded greatly in quality and quantity over the last 6 months where I'm at for work and everyday life. So now I've finally convinced my wife to drop them also and thus ending our 12 year run with Verizon and their devolution into Apple-like "It's our way or you don't need it" business model.
Will I ever go back? Not until I can buy a new phone from anywhere I want and activate it on their network. And I believe it'll be a cold day in heck before that is ever allowed to happen!

Taking my Note 2 to T-Mobile

So after years and years with Verizon, I have been mulling over the idea of going 'back' to the Big Pink [T-Mobile]. I have grown tired of the high prices and locked phones from Big Red.
When I got my Note 2 [the day it came out], I was disgusted by the logo on the home button and locked bootloader. Not to mention the V is painfully slow at rolling out ANY updates. With T-Mo's new pricing schemes it's just too hard to resist any longer. So having the Note 2 I was aware that it was a global phone but didn't carry the LTE radios for T-Mo's network. But I was also aware that APN's could be modified to work on the 'Uncarrier' network with relative success. I decided to give things a try.
I found that by modifying the APN's with APN Manager Pro, I could in-fact get around 21Mbps down and around 2 up. I have attached a screenshot of my Speedtest results. The top one is on Verizon and the bottom one is on T-Mobile using a Verizon branded Note 2.
View attachment 2327846
I really just wanted to let people know that it is possible to switch to T-Mobile and keep your existing Note 2 should you so choose to do so.
Thats some pretty impressive results. I was thinking about making the same move. Unlimited data with T-mobile is sounding very tempting and with those speeds you posted it makes it even more tempting. Im just gonna have to see about the reception coverage for T-mobile to see will it wok in my area. Thanks for the post.

[Q] Which section should I be in if I'm using this phone with T-Mobile?

Hi,
I am new to GSM networks and sim cards as I am coming from Sprint. Crappy 3G and our LTE in Las Vegas won't go live anytime soon so I am trying TMobile. I scored a good deal on an LG Optimus G, and I have it unlocked for TMobile.
I want to unlock, root, and flash roms. Should I be in the ATT section or the International Optimus G section for downloads/instructions?
Thank you,
Kevin
Las Vegas was actually the first city in the US where T-Mobile "flipped the switch" and turned on their 4G LTE service last November, a few weeks after the iPhone 5 came out (that was part of the reason, actually). I live in the downtown area and get somewhat "ok" coverage; T-Mobile's 4G HSPA+ is fine with me as I pull typical speeds well in excess of 10Mbps so it's a non-issue with me.
My LGOG can do the T-Mobile LTE without breaking a sweat, just requires me to add the fast.t-mobile.com APN (epc.t-mobile.com is fine for HSPA+ stuff, that might change in the future but I doubt it). I use their $30/month plan like so many others without any issues worth even mentioning.
If I misunderstood what you said and you were meaning that Sprint doesn't have 4G LTE here in Vegas, you'd be wrong on that count too (up to a point) but it depends on your area - they are currently testing it and I have a neighbor who noticed it last week on his Sprint device (think it's an S4, can't remember at the moment). We have a Sprint "switch" here in downtown about a half block from where we live and there's a cell site just off it so Sprint has the downtown area pretty saturated but it's not on 24/7, pretty sporadic as they're in the last testing stages before turning it on full time.
Anyway, as for the right sub-forum, it depends on which LGOG you have: the International version is the E975; the Sprint model is the LS975, and of course the AT&T model is the E970 which this specific sub-forum is about.
Choose where you want to participate by the model number/designation, or just participate in all of them I suppose. I'm going to guess you have the AT&T version since a) it's a GSM device (Sprint's is CDMA but uses the SIM card for LTE iirc), and b) the International version is factory unlocked from the gitgo anyway so...
You're in the right place, I'd say.
The process is fairly simple:
- use the ZV9-ZVB-Universal-Root (search for it) and it'll root the phone in a few seconds then reboot it ready to go (make sure to upgrade the SuperSU if you stick with the stock ROM or intend to keep it around in a backup)
- use FreeGee (get it on Google Play Market) to unlock the bootloader and install the recovery (two versions of TWRP or a touch-based CWM 6.0.2.7 are the choices), make sure you back up the EFS info before and even after you do the unlocking, it can't hurt
- copy ROMs to the externalSD card (or internal, I suppose) and have at it
Very nice device overall, my personal recommendation would be to avoid that Nexus 4 conversion since a) you lose the microSD slot totally, and b) your storage gets cut in half from 16GB to 8GB (not sure if that's ever been resolved at this point). Realistically while it's a neat idea in practice, doing it gets you basically nothing of any real use. The ROMs available nowadays as compared to long ago when that conversion thing was first discovered make the necessity of "pure AOSP as a Nexus 4" pretty much useless at this point in time. The LGOG is one damned fine device, seriously, and doing some tweaking with a custom ROM and some kernel stuff will net you an even better device.
Last edit, I swear:
Pick a radio as well. The stock JB AT&T modem works just fine for me, there is a hybrid one (33_84 meaning it's the core of the older .33 radio (like the LTE support) merged with stuff from the newer .84 radio (which doesn't support LTE) - the hybrid of both gets you LTE support and the other newer goodies too. Note: the JB AT&T radio does support LTE just fine, obviously, and it works with T-Mobile's LTE support here in Vegas and elsewhere too so there's no logical reason to go swapping out with radios unless you just feel like testing things for yourself. The danger with the radio swapping is a potential brick if the flashing process corrupts something; you may not recover from it in terms of phone usage but then you'd have a nice clone of an iPod touch with quad cores and everything!
I tested the .33, .33-.84 hybrid, .48, and finally I just said the hell with it and put the stock AT&T JB radio back on it and haven't had any reason to change it again, it works just fine on 4G HSPA+ and LTE combined.
Thanks a ton for the help. I literally just got this phone. I'm at work and like the posts above I'm having trouble getting lte....have to go
Well the info I posted above is tempered with the fact that it was my experience of using the GOG in that manner; you, like I have, posted in that other thread iirc where discussion is going on about the LGOG working with T-Mobile LTE then suddenly just not working and nobody seems to know why. In the short period of time where I did have it working it was great, had good speeds, very low ping times (one of those things about LTE that makes it faster), and somewhat solid connection/throughput for data transfers.
But, once that LTE disappeared from the status bar, it hasn't come back except the one time I swapped in another T-Mobile SIM and then it only worked till I rebooted (like 45 minutes tops) and when it came back up, no LTE yet again.
Kinda weird how/why this is happening, it could just be one of those things we'll never get a proper answer to or even a fix.
Regardless, the HSPA+ speeds are more than adequate to still be a very useful device. Personally I've never cared about LTE overall, and I know T-Mobile is getting there but they spent years building that HSPA+ backhaul network so that's good enough for me.

T mobile LG v60 to ATT?

I've seen a few posts saying you can cross flash so you can move your v60 from t-mobile to att. However none of them are very clear.
I am going to have to switch from t-mobile to att as t-mobile shut down the sprint network in an area I need to be with some regularity and now has near zero coverage. Their wifi calling doesn't work well either as it registers very slowly and doesn't stay registered.
I've waited over a year for t-mobile to deliver promised coverage replacements.
It's becoming more and more a problem as I need to be in the area more often. Would appreciate any details anyone can offer. I don't want to give up my v60 yet or have to buy one.
You will it informative. But please be advised that there is no firmware available for AT&T V60. So it is not possible unless your phone is factory unlocked by carrier.
You can't unless you don't mind it being a data-only device (and I can't guarantee even that will work). AT&T has a VERY select list (I believe this is by IMEI so cross-flashing will not help) of phones they allow to use VoLTE on their network. Other carriers' phones are not among them. You MIGHT be able to beg/harass customer service to whitelist your IMEI. I think I've read about that happening, but I might be thinking of Verizon. I wouldn't count on it though. AT&T has a vested interest in making you buy a phone you can't use anywhere else. They're not interested in BYOP mercenaries who want to try out their service for a month then bounce back to TMO or Verizon.

Sure,you can crossflash the T-Mobile version with AT&T firmware regardless of the IMEI and it will work.I'm on A12 AT&T with a USC V60 and have no issues at all.It will be required to have the AT&T firmware on it for the IMS to configure properly.I did this back when AT&T shut their 3g down to work around it.

I've seen a few posts saying you can cross flash so you can move your v60 from t-mobile to att. However none of them are very clear.
I am going to have to switch from t-mobile to att as t-mobile shut down the sprint network in an area I need to be with some regularity and now has near zero coverage. Their wifi calling doesn't work well either as it registers very slowly and doesn't stay registered.

The key thing,does AT&T work in that area?AT&T and T-Mobile are currently struggling trying to get 5g fully working in all areas and so far it's been a nightmare.I'm in Nashville,TN. and it's horrible in most areas.Even down to the 4g towers are degraded and data speeds are back to 3g speeds as we speak.It's not only T-Mobile at the moment.
Where did you get the AT&T firmware? And the process to cross flash?

Yes att works. No its not 5g in either case. Too rural. T-mobile for example replaced more rhan half a dozen towers for one town in the area with two. Two. Then wondered why people had no coverage.

I have been on AT&T for almost a month about how bad the service is around my home address.We have 1 tower in about a 10 mile radius that's trying to serve at least 10,000 subscribers every day and it's failing hard.I'm doing good to get 4 mbps down and .5 up.Yes,that's a dot in front of the 5..lol..I told them point blank,why shut down 3g when you can't even handle the load with 4g alone?My response was, "we're working on 2 towers that are planned to be upgraded to 5g by the end of the year."Those 2 towers haven't worked in 8 years I know of..lol...I remember when they activated 4g and it wasn't this bad.The worst part in the US we're down to 3 carriers period.T-Mobile,AT&T,and Verizon.The rest are all MVNO's so those don't account for anything..lol..

Tried a signal booster? I used to run a 3 watt (max legal) and it made service possible. Also If you have wifi/internet you may be able to request a microcel from ATT for free
