xperia play white r800a tmobile

Xperia r800a so I been searching and there are no answer to this. Can the r800a be use on tmobile USA? With 3g? I can't seem to find the answer to this anywhere any videos for a review with T-Mobile ?

You won't be able to get 3G on Tmobile with ANY version of the Play, as the required bands aren't supported. It's simply not possible.

Edit: You can use the phone of course, but it will only be Edge speeds.

OK then in this case is the r800i better? Or the r800a or the r800at ?
Getting a headache LOL
The reason I'm asking cuz I had dell streak b4 on edge and it wasn't that bad come to think of it on edge

You should be fine with any unlocked variant as long as you're okay with the limitations of edge.

Why is T-Mobile never get any love for 3g when it comes to unlock phones lol

I have an R800a and on t-mobile and I get HSPA(not hspa+)
gets around 120-150 Kbps down, not bad. But I would like to know how to stop them throttling my already bare min connection

I remember someone saying that the Japanese version of the Xperia Play has bands for Tmo.

(Q) r800at (att xperia play) on tmobile edge bands?

I have a white xperia play an r800at, and I thought I'd get edge T-Mobile but my phone says emergency calls only

To confusing so I removed it.

Of course, 3g isn't going to work, but this is another Guy with the exact same phone getting tmobile edge. The phone worked on ass bands in Canada as well so my friend I don't know why you're getting reception but emergency calls only.
Please see T-Mobile asap

If anyone has any insight or a r800 at working on T-Mobile please share

So do you think it won't work cause of the 1700 band issue or because you tried flashing different radios to it? I would call up tmobile but I already gave the phone to my friend otherwise I would call them.

The 1700 band is for 3g, edge should work without flashing anything, but give it a shot

That post you posted isn't from me, I was quoting someone else from the threads I linked you.
Ok this is all very confusing for anyone reading so to summarize, I have an r800at unlocked and I am not able to make calls on T-Mobile edge network however I am getting signal bars please help

Sorry about that I thought it was from you I fixed the post.

I'm not sure on how to flash radios otherwise I would try it just don't want to brick it or anything like that.

[Q] Bloatware-free ICS questions (LT28at)

Hello,
I just purchased an ion from the interwebski, and updated it to ICS through Sony PC Companion. AT&T sure has a lot of CRAP on this, and I have no option of removing as we all know.
Is it possible to find a clean stand-alone ICS from Sony and install it to the phone? I'll make the comparison of being able to download whatever Apple's new iOS is from their FTP site, and do a shift+leftclick and install that clean OS.
I'm not opposed to rooting the phone if it comes to it, but i'm a little gunshy due to the fact that every rooted android i've ever owned has gone tits-up.
I'm sorry if this is re-post, and thanks a million in advance for any help.
:fingers-crossed:

Root the AT&T firmware and remove bloatware or install generic international firmware (LT28i).
Don't ask how to do either of those as its already been posted.

Thanks for the response. I've been studying the forums and as many related posts for the last few days and I have a few questions. It also seems you are one hell of a source of knowledge for this phone in particular. Here goes:
1.) I cannot unlock my bootloader as per the *#*#service#*#* -- Does this mean I am unable to use CWM? Fastboot?
CM Nightly Discussion =
2.) How can I tell if this is an LTE or HSPDA phone? *I did read your discussion where a guy wasn't able to get a 4G indicator, and you advised him to call ATT and ensure he has the appropriate sim card. I don't see a 3G or 4G indicator on mine either way. I do however get a 4G indicator (but so did my iPhone 4s, which is definitely NOT 4G capable). I pulled this sim from my iPhone 4s and stuck it in this phone.*
I will edit this again later, I have more questions, but for now it's the end of a long day and my brain is fried.

1) you can still get CWM but not fastboot.
2) You said it was an at&t ion right? Then it should be LTE. Don't think the lt28h can flash the lt28at firmware because of the LTE though I could be wrong. Dial *#*#7378423#*#* and go into Servixe info -> configuration and see if you have the LTE bands listed.

Thanks for the reply.
What if I was to just put a different bootloader on the phone?

Go to Settings --> Apps --> All, go to each AT&T app and click Disable.

You need to understand what the generic "4G" is
1. The iPhone 4S is "4G" but not LTE. There's a big difference (3G in my area is 2-3mbps, 4G is 5-6. LTE from people I've seen can be 40mbps+)
2. The 4G icon you see is most likely just HSDPA. Do a speed test. If it's insane high, it's LTE. 10ish or less, it's 4G
3. The LT28at is an LTE capable phone
AT&T and others throw around the term 4G for people like yourself and others who think that "4G" is the fast data. It's faster than 3G but not THAT fast. Think of 4G in reality as 3.5G

How'd that work out? Last time I flashed stuff like that was before ICS out and when I flashed it I messed up somewhere along the line it bricked and I had to send it in for a warranty replacement!

Well, I used bin4ry's rootkit v13 (v12 and v14 didn't work out real well) with Lt28i ICS (courtesy of flashtool).

I flashed the i FW, rooted, flashed CWM and the deodex files then my phone froze and I had to force restart. It was soft bricked and just now is finally to where I can flash it

[Q] Signal issues i747 on T-mobile. Any help or suggestions appreciated!

I have an unlocked AT&T i747 on T-mobile's $30 100 min unlimited text, and 5GB 4G data plan.
It is running a fitsnugly nightly build of CM 10.1 for d2att
Was previously running Leankernel and now i'm running Ktoonsez's kernel
I unlocked using this method.
The Issue: My signal switches between H+, 3G, E, and rarely G. All while being in the same spot. It spends 90% of the time on E.
This happens in areas of great reception, indoors and out.
Rarely will H+ happen and 3G is very sporadic too.
I live in the heart of a major city (Boston) where T-mobile is prepping LTE so I can get their 3G/4G on the refarmed 1900MHz and without AWS.
My IMEI is listed in the status section.
What I've tried:
Before doing any modding of my phone, I previously backed up my EFS/IMEI with Andromizer (XDA link). Restoring it hasn't changed anything.
Changing network modes (LTE/WCDMA, LTE/GSM/WCDMA, GSM/WDCMA preferred)
Enabling/disenabling data roaming
Changing APN settings (The choices were T-Mobile US and T-Mobile US LTE)
So would flashing Tmobile radios help? Tmobile/d2tmo ROMs?
TL;DR: MY ATT I747 ON TMOBILE WONT KEEP THE H+ OR 3G SIGNAL AND IT SUCKS AND MAKES ME WANT TO CRY. PLZ HELP PLZ PLZ PLZ
Seriously though, any help would be appreciated. Thanks everyone! If you need anymore info Just let me know.

That "free" unlock method always made me suspicious and I've seen other complaints like this...

You may want to try flashing t-mo radio/modem. Do a nandroid first.

This is pretty frustrating. I changed my modems to an older ATT one, and now I only get 3G sporadically and 90% of the time its on G. So odd...
Also I'm pretty sure I'm specifically not supposed to flash a T-mobile modem....

[FTF] Xperia ZL (C6506) 1270-4005 10.4.B.0.569 Generic North America

Here's Generic 4.3 for North America... C6506_1270-4005-10.4.B.0.569 R1C_LTE North America Commercial and Journalists.ftf

sweet, has it been tested on a C6506 ?

That's Commercial and Journalists, right? Cause Generic would be 1270-7584 (which doesn't have the update still, just checked) and this one is 1270-4005.
But, eventually, who cares. I was pretty sure we won't get update on Holidays, either before or after.
Merry Christmas!

Unlocked (Sim) Bell Xperia ZL 6506 on Wind Mobile running this just fine.
Had to readd the APN, which scared the heck out of me before I realized I had to do that. Hah.
I'd post a picture but apparently I can't until I have 10 or more posts..

lol, yeah, learned about APN last time when I flashed generic 244 lol.... I decided to install it, so far so good. first thing I did was input the APN settings for Rogers lol... automatic download settings never seem to work for some odd reason
- Most noticeable, Camera App is much better....
- Keyboard is faster
- Phone is running hot again though..... With 4.2.2 it stopped getting hot the last month or so, ZERO Changes to the phone,maybe it will go away again, who knows... strange none the less.... maybe its a learning process with the OS...no idea lol

I flashed it & lost LTE. The APN is still the same, I'm with Rogers. Any idea what might of happened or how to fix it?

Well it looks like I can get LTE occasionally, but I'm not getting any 4G HSPA+, it;s either LTE or 3G

I tried flashing just the baseband of the 4.2.2 FW but only got a bootloop.

Why are you flashing the 4.2.2 baseband? This 4.3 firmware contains the AMERICAS-LTE baseband, so it has the baseband for AT&T LTE or whichever 4G operator you are on in North America.

Because the 4.2.2 baseband was the last one that worked. When the 4.3 first leaked with the C6503 journalist FW, I flashed that & that's when I lost 4G but still maintained EDGE 3G & LTE. So I flash this new C6505 FW & I can still only connect with those bands. I'm with Rogers & I have all the correct APN settings, I'm so confused with what's going on, because I know this should be working & I have no idea why it isn't.
My baseband right now is 9x15A-ACEFWMAZQ-3011082-51

The c6503 baseband was GLOBAL_HSPA, so if course it wasn't going to give you the AMERICAS LTE frequencies. The existing 4.3 c6506 firmware has the same baseband frequencies as the c6506 4.2.2 - go to the service setting and see for yourself, both say AMERICAS LTE.
Not sure why you would be seeing a difference as all c6506 releases are in fact built with the North America LTE bands.

LTE off you wont get HSPA + on all the time, only when LTE is off and your using data HSPA + will show up.... That's how its always been for me on Rogers which is a good thing.

For what it's worth, I'm getting LTE connections on my C6506...

OK so the truth is that, I really like interactions and interface of the new 4.3 on the ZL but its seems to have much bugs than 4.2.2 versión 244, the phone freezes some times when browsing the web with chrome, and the camera quality is not sooo good. I like how smooth it is, but my phone freezes 2 times and I had to press the yellow one......battery performance seems to be much better when using stamina, but Im back to 4.2 MUCH MUCH stable, no bugs for me, no freezes, and camera prformance seems to be much better. I think il w8 for the 4.4

The baseband will be 100% the same and there may be one or two APKs that differ, mainly store / retail demos.
