I'm interested in getting the xperia T but leaning more towards V. Does anyone know if either phone will work with us tmobile hspa+ network?
i got tx and i get download speeds up to 9500kb/s, 3000,mb/s for upload.

Hmm and TL/V/htc One s have the same frequency as well so does that mean on tmo TL/V will work on the hspa+?
TL don't have 3G 1700mhz, V don't have any 1700mhz frequency that are needed for t-mobile 3g/4g network
htc one S is 3G/4G ready
I use my TX on WIND Mobile here in Canada and it works very well so far.

Strangely, my China TX with HK .197 seem can't get the hspa right with Rogers.
It only shows 3G icon, never H ( which my xperia S did) .
By checking the network status, it jumps between ustm:3 and hspap:15. My max download is just around 4mbps...
Sent from my LT29i using xda app-developers app
same here, 3g no h, rogers and tx
Definitely get the T if you are gonna use it on tmo us, it's a pentaband phone and I get about 17mbps down.
Not So Fast -- 1700MHz is not required in all locations for T-Mobile HSPA+
T-Mobile has launched HSPA+ service on its 1900 MHz PCS spectrum in several US cities and the company has promised it will
have a "material" footprint of refarmed 1900 MHz spectrum by year-end (2012). This project should be completed sometime in 2013.
Depending on where you live in the US the LT30at will support HSPA+ on T-Mobile on its 1900 MHz PCS spectrum now if it can be unlocked
and most certainly will sometime in the future.
Does anyone know for sure if the LT30at can be unlocked at this time?
Also, I have seen several posts with regards to the LT30at specifications -- some include the 1700MHz band and some do not --
Can anyone confirm for sure if the 1700 MHz band is included on this phone?

therefore, TX will benefit its new 4G and even 3G service?

I asked the guys at the Sony Store if they sold it unlocked, and they told me yes.
Just got my Xperia TX and it works fine on T-mobile. I get H for HSDPA aka T-mobile's 4G.

Hmm this is getting me more and more interested in Xperia now.. would go for V (screens over 4' just get too big) but if only there was a way to confirm hspa or future tmo lte would work on the V.
Most of these store reps don't really know a lot, I worked as a tmo associate for a brief time its not like we got any special info.

I see TX has the 1700 band so that's gotta be it, T does too actually so I'm thinking they would be good.
I can confirm that the Xperia TL AT&T ( USA )work with T-mobile ( USA ) 3g / 4g Network. and it downloads and uploads faster than my Galaxy S3

So , i long story short , seems like this device doesn't support Europe 3G bands , so is there any rom , or any tutorial how to unlock them?
i've tried changing NV values from QXDM , ect... but with no luck . I only get Edge (2G)
Anyone with G2 mini , or international version of L90 , can tell me NV values? (1877 is most important)
I'm on stock kitkat
I think, since it's a T-Mobile version of the phone, it's not possibile.

I agree.
Phones bought in US won't work fully in Europe and phones bought in Europe won't work fully in US.
That's why shops like amazon tells if phone is US-only or International.
I don't think you can do anything about it. It's probably hardware related or software.
It doesn't not appear to have UMTS 2100 (Band 1?), which is what I believe you need in Europe. Many of T-Mobile's phones do have that band, just not the L90.
I had the exact same problem with the d415. I recently went on a two week trip to England, France, Switzerland, and Italy and only 2g worked in all of those countries. On the plus side, you'll get absolutely blown away by the speed when you come back the U.S.
You will only get 3G out of the country if you are:
On a network with the same technology that is available in your phone
You have an international data plan - and your carrier allows international roaming
You are allowing your phone to roam internationally
Also sh(w)ould work on an unlocked phone of the same specifications

Several places that I have looked around say that the L90 (all variants) supports UMTS 900, 1900, and 2100, and all areas in Europe with 3G use one band or another.
IF you weren't able to achieve such a connection this would be an issue of carriers, or the plan.
I bought a Xiaomi Mi Note LTE (Dual Sim) from China recently but cannot use LTE 4G in the UK.

It turned out that Mi Note LTE (Dual Sim) support LTE B3 and B7 (The international version supports B1 and B3)
But my carrier Vodafone UK rolled out LTE throughout the courtry with band 20 (800Mhz) but LTE Band 7 is only available for 3 cities at the moment. ( Only EE and Three support B3/B7, which is the reason I cannot see 'Vodafone 4G' and 'O2 4G' but 'EE 4G' and 'Three 4G' in the network list. source, source, source)
So I tried the guides: here, here, here and here to unlock B20 on my phone. (Many thank to @BlackSoulxxx, @fffft, @olokos, @devilsshadow and @Albirew)
I went through all the steps and set the value into 6828 (and even 6829) permanently but still cannot see 'Vodafone UK 4G' or 'O2 UK 4G' on the network list.
I googled a lot but still couldn't find the solution.
I found others who have Xiaomi Mi Note or Redmi have the same problem and want to unlock different LTE bands. But some of them stuck in the middle of the steps especially the prerequisites and couldn't go through. Maybe unlocking other LTE bands is working for them. So I decided to write the step by step guide and hopefully throw out a brick to attract a jade.
The lawyers made us do it.
We have to post an obligatory warning.
We don't think that this mod will cause you any problems. But we can't guarantee that. I never tried it on devices other than Mi Note LTE (dual sim).
You assume all risks if you proceed, including the risk that your phone might object, meltdown, brick or void your warranty.
Let's start
1. Root your device.
2. enable diag mode by entering *#*#717717#*#* on the dialer and download the driver from here (thank @m11kkaa).
Once diag mode enabled, you can see the Device Manager from PC like this:
then right click the first 'MI NOTE LTE' and install the driver you just downloaded
you will see this if successful
3. Download and install QPST
4. Download and install QXDM
5. Open the "QPST Configuration" program, you should see below straightaway:
You couldn't see this until you finished step 2 successfully
6. Now select the QPST Start Clients > Software download > Backup > Start. Wait until the status says 'memory backup completed'. This saves a backup copy of your phone's stock NV memory to your computer in case you need it later.
7. Leave QPST open and navigate to the C:\Program Files (x86)\Qualcomm\QXDM\Bin folder. And right click on QXDM.exe > run as administrator.
8. Go to options -> communications
Target port -> select COM6, then OK
9. select Nv Browser from view
10. select LTE from Category Filter, then you can see 06828 and 06829
11. click on line 06828 (lte_bc_config); click the Read button, save somewhere the original value in case something goes wrong (inside notepad or anything), the original value on my device is 2061584302148
12. Let's talk more about the value, source
in my case, the value for 06828 is 2061584302148, using Calculator (programmer mode) to change it to binary value is
11110000000000000000000000000000001000100
from right to left, the 3rd, 7th, 38, 39, 40,41 bit are 1, which means band 3/7/38/39/40/41 are enabled
I want to enable band 20 so change the 20th bit to 1
11110000000000000000010000000000001000100
the corresponding Dec value is 2061584826436
13. click on line 06828 (lte_bc_config); click the Read button, replace Input value with 2061584826436 (please don't be an idiot and don't edit the empty one with "ext" in the name) and click on Write button
OK THAT IS IT. Restarted Mi Note, and then see if the value set permanently.
BUT LTE BAND 20 IS STILL NOT UNLOCKED.
I changed the value to 2061584826368 which is
11110000000000000000010000000000000000000
Disable B3 and B7 to see if the value is working, It worked, I cannot see EE 4G and Three 4G any more.
let me know if anyone unlocks other bands
ps: don't forget to disable diag mode by entering *#*#717717#*#* on the dialer.
DID I MISS ANYTHING?!
and thanks in advance for any idea.
Thanks @BlackSoulxxx, @fffft, @olokos, @devilsshadow,
@Albirew and @m11kkaa anyway even if I couldn't unlock Mi Note, I had a lot fun playing it.
how do u calculate the NV value for 6828? in my case i needed band: 1, 2, 3, 4, 7, 38, 39, 40, 41. could u get the value for me? thankyou

Hello,
I need to unlock just one band on my Redmi Note, band 20. I don't have a Mi Note, I have the cheaper more affordable option the Redmi Note 4G.
However, I know this trick will work on it, it's a similar Snapdragon chipset, I just haven't tried it yet, as I'd love some advice before diving in.
Currently, my phone has:
FDD-LTE (1800/2100MHz) & TDD-LTE (2600MHz)
So basically, that's band
2100Mhz - Band 1
1800Mhz - Band 3
2600Mhz - Band 7
I'm on Three UK, which only has 2 bands on it's current spectrum,
Band 3 and Band 20, which of course is 800 and is NOT unlocked by this phone.
Is it possible to unlock Band 20, without losing other bands. I only need Band 3, and Band 20, and I'll have full 4G support.
10000000000000000000000000000000000000101
Yikes, this is my binary. Which is more confusing than ever. I get that it's little endian, so that means left to right, 101 that's 1 and 3. I'm confused though why Band 7 hasn't got a bit and what the very last bit refers to in my case.
---------- Post added at 01:41 PM ---------- Previous post was at 01:33 PM ----------
OK. I think I've found my mistake. Apparently, it supports Band 3 and Band 40. So maybe not Band 7 after all. This would make sense.
Band 1
Band 3
Band 40
I'll work it out for sure now
---------- Post added at 01:50 PM ---------- Previous post was at 01:41 PM ----------
Balls
10000000000000000000000000000000000000101
There's 41 characters there. That's now messed up my head because surely that means it supports Band 1 and 3 and 41, not 40. I'll continue to work on this.
---------- Post added at 02:00 PM ---------- Previous post was at 01:50 PM ----------
Nope. I was right. I downloaded LTE Band Calculator off the Play Store, and 1 3 and 41 = 1099511627781, the number in my NV RAM.
What the hell is going on!!? I've read this phone supports 1, 3, 7, then it was 1, 3, 38, then 1, 3, 40... Now my NVRAM tells me it's 1, 3, 41.
Christ almighty. Apparently, band 41 is accessible from devices with Band 38 unlocked, but that doesn't make sense because India is running on Band 40.
Seriously, getting, pissed, off.
OK. An update.
I set my value to 10000000000000000000010000000000000000101 which is 1099512152069. This is Band 1, 3 20, and.... 41, which was apparently unlocked before. Not convinced though.
So far, can't tell whether it's actually done anything. EE 4G is still there, which makes sense because they have strong 4G in the UK. O2 which has piss poor 4G in the UK, only use Band 20, so seeing that as an option in the Network selection list would be a perfect way to check how valid this experiment is. I'm currently in Wilmslow in which O2 suggests I should have strong coverage, but nothing showing up yet, only EE.
However, I'm in a building, and it's a big building, and signal varies. Really, the best time to know is outside. Perhaps I will get O2 showing up with 4G in the network selection as an option.
The saga continues
---------- Post added at 03:23 PM ---------- Previous post was at 03:19 PM ----------
Hah, another update. OpenSignal map, which uses data collected from actual devices shows that O2's 4G data is piss poor in Wilmslow (despite their claims). I'll wait then, and report back with further results
what is the device code? mine HM Note 1S CU KHKCNBL.
Bad news, looks like you can't unlock band 20 OnePlus One users found this out. Perhaps you can't unlock band 20.

You did a great job on this tutorial with a load of screens.
Have you considered there may be hardware limitation concerning LTE20 ?

My last couple of posts seems to possibly clear this up. It's very possible that Qualcomm haven't enabled Band 20 in the modem.
I wonder though, if we flashed a modem for a different device, whether we could unlock band 20....... food for thought isn't it?
---------- Post added at 04:06 PM ---------- Previous post was at 04:02 PM ----------
From the Zenfone 5 with the same chipset, again no band 20:
GSM: Band 2/3/5/8
WCDMA: Band 1/2/5/8
TD-SCDMA: Band 34/39
FDD-LTE: Band 1/3/7
TD-LTE: Band 38/39/40/41
From the Lenovo 856:
(4G): FDD - LTE: B1 (2100 MHZ) / B3 (1800 MHZ)
However, contradicting all that, from Moto G 4G, which uses the same chipset:

European model: Bands 1, 3, 7, 8, 20 (800, 900, 1800, 2100, 2600 MHz)
So from a purely hardware perspective, it looks as though it's very possible to do this. I wonder if flashing a Moto G 4G Modem would unlock Band 20....

It's possible, we need to flash a Moto G 4G Modem though.... now, talking about it is easy, but how we do it, without killing our devices, that's where it becomes fun, because I doubt we can just flash the baseband and assume it'll work. That's got lost IMEI written all over it.
Thanks for all your hard work AMD details how to. I'm able to add those band to my Redmi NOTE 4g but unfortunately, nothing works. I believed it's the hardware limitation. My Redmi Note 4g only supports FDD-LTE band 1, 3, 41. I needed band 2, 4 to beable to work with my US network.
Luckyly, I'm fortunate to purchase a HK model of Xiaomi Redmi NOTE 4G. this one ssupported FDD-LTE band 1, 2, 3, 4, 7! I can now use my US tmobile LTE network without any problems!
The questions I have now is:
is there any way to extract the modem that I have in the HK model Xiaomoi Redmi NOTE 4G and make a flashable zip file to flash it in my China Model Redmi NOTE 4G using CWM recovery? I would LOVE to help those people who bought the China model of Redmi NOTE 4G that couldn't use the LTE in the States. Anyone knows how to make a flashable zip with my modem in it?

Thanks for all your replies guys.
I remember last time I flashed this kind of thing is when I was still in uni and flashed BIOS on motherboard......over 15 years ago......
Flashing the modern or baseband sounds promising but dangerous as well.

It's the same phone with the same chip and everything. It's not from a different phone with the same chip I'm talking about in my case…
China model of Redmi NOTE 4G is widely available on the net (FDD-LTE band 1, 3, TD-LTE band 41). And it's the ONLY model that people can buy at the moment. So people who bought that were pretty much stuck with HSPA+.
So. If any XDAer out there know how to transfer my HK model (FDD-LTE band 1, 2, 3, 4, 7) modem or baseband to the China model will be much appreciate! It's almost impossible to purchase the HK if u r not living in HK.

I remember last time I flashed this kind of thing is when I was still in uni and flashed BIOS on motherboard......over 15 years ago......
Flashing the modern or baseband sounds promising but dangerous as well.

I loved the Mi NOTE! I like the design dual glass and OIS camera. I'm hoping to purchase the Mi NOTE PRO when it come out next month. But having incompatibillties LTE band is the only problem keeping me back. I've been with Xiaomi phone since Mi2s. Now I'm using the HK model Redmi NOTE 4G because it's the ONLY Xiaomi phone right now that is 100% working with US LTE networks.
Xiaomi's 1st Global Mi phone code named "i" will be announce on the 23rd this month in India. Rumors said Xiaomi called this model the "Global Mi Phone" was because of the 4G LTE it supported. So if the Mi NOTE PRO has the same band as the regular Mi NOTE, guess my next Xiaomi phone will be the "i"…
Isn't it a case of Global Rom vs China ROM? The Global ROM flashes the global modem although, I've got a global ROM and i had 1, 3 and 41 myself.

nope. flashing the global rom will not change the modem of the phone. my HK model of Redmi NOTE 4G came with HK version of MIUI V5, then updated to Global version of MIUI 6 and now i'm using the Chinese version developer rom. and my 4G works on all 3 roms.
if that's the case, it might be the LTE antenna were different.....but we needs some expert to confirm this.
I'm not even aware there was a Global version and a HK version
Xiaomi Redmi Note 4G LTE band unlock - Tutorial
Thank you very much for this wonderful detailed explaination, @GeorgeZZzz. Unlocking addtitional bands worked like a charm. Sadly as with each of you, there was no success on finding any LTE connection on band 20. I'm curious how bands 2, 4, 7 or 17 will work during my planned summer vacation in the US. Since after reading several of the previous unlock threads I fear it's all antenna related and not so much a snapdragon/software unlock issue. If that's truely the case we won't have any luck.
However during my unlock session in QXDM I had an interesting find:
Only an idea, but maybe the bands are additionally hardcoded into the firmware?
Anyways, it's nice playing around and thanks once again @GeorgeZZzz for making it easier with your "tutorial". :good:

I don't see much past 2G use in your country at the moment
Here in central NC I am getting around 5 Mbps download and around 1 Mbps upload. This is just from my home, I haven't taken the phone anywhere else yet. I hope to get a couple of test from other areas around my town today.

Unfortunately no, its a hardware issue. Unless the radio could be modified. The only current band that is disabled but can be opened is band 12, but that is not going to help in your country. Sorry

Sorry, Kinda weird the 6735 is a world capable SoC, even if it was for a US market, why cripple it?? I wonder with an unlocked bootloader if flashing another 6735 based radio would work?? Probably not that simple.... Sorry could not help out

I think available bands were determined by nvram and modem and without the modem sources we can't unlock any new bands

The Indian LTE is on band 40 across providers. LTE band 3 is also auctioned by government nut service yet to be started on that. Its a hardware radio issue and not something that will get corrected with software OTA.
Its limited to 3g use. I too have the US amazon version and its not possible to use it on 4G.
