T-mobile 4g Radio

OKAY so I decided to update this thread:
There are two versions of the One X. One with aws bands and one without. I have a device without AWS (I am about 80 % sure). There are reports of people getting 4g on AWS with the Rogers Version as of now, and more testers need to check it out as it could still be possible on ATT.
This flash here theoretically could enable the One X radio to lach onto AWS (The radios here are for the One S Ville.)
http://ville.giev.de/?page_id=42
I have flashed all three, and although I did not get 4g, I got faster ping and a near immediate connection onto T-mobile. To all the people saying this will "brick" the phone, it does not and you have nothing to worry. But as always make sure to do a backup. The radio hacks for the Skyrocket/Note were also based on flashing the Galaxy S2 radio directly on top. This should work the same.

I'm interested in this as well. What does is involved and the risk? I don't have warranty on my phone, so I'm a little bit leery in being first.

if your rooted ull should be fine just make a back up of ur current set up. this is just a clockwork flash, it may not even flash, but if it does then there's a high chance of 4g.
i've done radio hacks before for the droid 3/skyrocket/note all from a similar concept. ex. flashing the t-mobile galaxy s2 radio on the note, to enable 4g.
if anyone could provide me with a better solution for an unlock i am sure i can get this to work. seems that the htc unlocker server is down right now
it's the same thing as flashing different radios via clockwork posted in the One X android dev forum

I'll give it a try, hopefully it won't mess anything up. So I just flash the radio in recovery. If no good, I just flash the correct radio again?
There is a one click no HTC Dev bootloader unlock in the Dev forum.

I flashed:
Radio from RUU_Ville_U_HTC_Europe_1.78.401.2 [Recommended] (update by rhcp)
0.16.31501S.17_2_10.23.31501S.10L
From your link. It flashed correctly. The phone on data and voice still works. I confirmed the version in Settings is not my original:
0.17.32.09.12_10.86.32.08L
I'm still on Edge, but I'm in a crappy cell area, so still not certain if radio or my area. I might give the:
Radio from Stock T-Mobile US (update by rhcp)
0.16.31501S.02_10.18.31501S.08L
Radio a try too.

good to hear no negative results got my phone unlocked so i will be testing tonight. also do u guys have the newer sims or older ones?

I have an older sim I believe. It is one that came from an activation kit I bought off ebay. I tried the T-Mobile radio and same results, still on Edge, but still could be my location.

What in gods name are you guys doing! ? Are you trying to brick your phones? It's already been confirmed that the hardware on this phone does not support the proper bands for T-Mobile 3g!

It's not just the SOC that determines hardware compatibility. There are various radio amplifiers and filters which are tuned to the specific frequencies that the phone is likely to encounter. If a phone is going to be sold in multiple markets, sometimes the hardware filters are set up for all frequencies and some are disabled via software, but often times this is not the case.
It's not impossible that a radio reflash can make it work, though highly improbable.

Interested in this. There might be better luck flashing the tmo radio since I don't think any European operators use AWS bands, correct me if I'm wrong.
Can anyone explain why flashing this radio from a different device won't brick our phones?

I have a tmobile one s, but i also have the one from att and i am so interested on using this phone over tmobile 4g let me know if i can of help. I am using my micro sim that came with the one s and i am getting edge (asume its the latest from tmobbile 4g mucro sim. I am on 1.85 rooted but i did not unlock. though i am sure we can flash through CWM. any ways i am sure there is a way out to get 3g or 4g on the one x on tmobile did not find the way yet.

flashed both of the t-mobile modems no luck for me either, although my ping is significantly higher and connects to t-mobile a LOT quicker.
does anyone know how to edit the LTE settings. it is odd but for most ATT LTE phones they have the 1700mhz frequency i think it would be a matter of just defaulting that....
the radios also show up in my baseband so i have successful flashes
EDIT: one more thing, before i was not able to use data at all considering i had the newer t-mobile sims but now data works but on edge speed.

it's just a file in your system. it could potentially brick your phone but you can always get into recovery and restore. which is why i stated you should create a back up of your device before trying it out.
however, i was fairly certain it wouldn't do that because the internals of the One S/One X are nearly identical, they both share the same processor and most likely similar (if not same, radios).
either way, the the radios work, getting me higher ping, and working data without having to switch out my sim for an older one, hope there is a way to activate the 1700 band !
http://www.gsmarena.com/htc_one_x_at&t-4614.php
EDIT 2: apparently there are two models of the ATT One X/XL one with the 1700 band and one without

Likely the software has been changed to support T-Mobile, but the hardware (filters, amplifiers, etc) are non-existent, so you'll never get actual 1700 MHz AWS support.
Of course, this is just a 50,000 foot view perspective without actually trying it myself.

you might be right about this one but there are certain One X/XL's that do have the 1700 band found out through some searching and trying to figure out the reason behind it.
If that's correct.... the people with the 1700 band would have 4g when they flash this radio! also use *#*#4636#*#* to change network type to lte/gsm
--- for other phones though like the Skyrocket/Note they were directly compatible with T-mobile radios.

Okay, I flashed the Tmo One S radio and did not receive a brick. What I did receive is a not-so-good connection that will switch between HSPA+ and 3G quite often.
I don't have a WIND sim to test with, but I tried running AT commands on my phone and they don't seem to be working. I tried doing a network scan with AT+COPS=? waited forever and had nothing displayed.
Strange...

Rebooted and ran the commands again. Still don't see any AWS carriers.

Don't you need a wind sim to connect im pretty sure the Canadian version will work on aws

Confirmed on my end that even with the T-Mobile radio, I'm not getting HSPA+. Even when I drove by the Moscone center where 1900Mhz was refarmed during Apple's WWDC (maybe it was just that day?). I was hoping this would be like the Note and Rocket where I can flash different radios.
Any other new phone capable of this? The S III? If not, I may have to either wait for 1900MHz refarm or switch to Straight Talk.

Picking up an att s3 today to test it out. Most likely there's two versions of one x one with aws and one without. I know mine doesn't though.

I'm not exactly sure of this one.
If someone is willing to let me cut up their WIND sim (or lend me their WIND microsim), I'll re-flash the tmo radio and meet you somewhere to test it (Toronto, please).
~dan
-----edit-----
Just popped in an old WIND sim that I used to test AWS connectivity at first. Saw WIND Away with the standard radio, and after flashing the Tmo radio I see WIND Away and AT&T (AT+COPS=? shows Rogers, ATT, Telus, Bell).
I live by the lake, that would explain why ATT shows up.

[Q] Compatibility in the US

Hey,
I'm heading back to the US after being in SK for a bit. I'm considering getting a LG LU6200; save for the battery life, it's an amazing phone for the price. Anyway, I'm wondering if I'd be able to use it in the US.
I saw that the phone operates on the 2100 band for 3G (HSDPA), which Metro PCS and T-Mobile operates on accd. to Wiki, and the 800 band for 4G, which Sprint operates on.
Theoretically this should be possible, but I've just had a friend who's moved back to the States w/ the same phone that said something to the effect that he couldn't. But he also only tried Verizon. =/
Since most folks here probably haven't used this phone, I'm wondering whether or not you've been in a similar situation that ended in success. (ie Have you been able to use a non-US phone with US carriers?)
Also, I'm wondering whether or not this is a good idea since I'd be restricted to a single band, which I assume increases the likeliness of dropped calls/weak signals, etc.
I've asked other forums, but haven't really gotten a response.
Thanks

[Q] How can the 4G frequency be changed from 1700mhz to 1800 mhz

I've searched for 3 days now, trying to get some info on this, there are various discussions on xda and on other sites that come along the same line, most of the answers are:
No it can't be done - it's hardware related - there are different variants for each region (seems this is not the case with the ONE)
You need someone with QPST but it probably can not be done.
But there is none that actually clears it up, it's mostly "I think it is...................."
What I found out is that the chip regulating 4G LTE connectivity on all HTC one variants is the same (600 MHz Hexagon QDSP6V5A part of the MSM8974 chip and it can sport the ALL LTE frequencies), so it is not a hardware difference between the EMEA and the Verizon, now the question is do I need someone with this QPST or will it only be a case of changing the baseband - all this, is my own conclusion, feel free to give me feedback on this
now on the Verizon site LTE spec says:
Network: LTE Band 13/4 (700/1700 MHz)
CDMA/1xEVDO Rev. A (800/1900 MHz)
the HTC site for Verizon says 4G LTE:
EMEA: 800/900/1800/2600 MHz
Verizon: 700/AWS/1800/2600 MHz
Yet I still don't get any 4G
Sadly there is so much info and it's hard to follow it all. So please can someone explain what and how things actually work?
Why do I need to know all this? Cause I have a Verizon m8 and I'm using it in Europe and I can't get 4G - atm I'm using Insertcoin with ElementalX 8.0.5 kernel and everything is working on the phone aside 4G - I flashed various roms on it, never had ANY problem, aside small things that a Google search solved.
Anyone that can enlighten me? Any help would be appreciated.

Each model must have a different *antenna* configuration so that they are optimized to their respective regions. The *antenna* is separate from the actual radio you mentioned above. This is why there are so many models, which I thought I had explained in this thread: http://forum.xda-developers.com/showthread.php?t=2710720&page=5
Even if you could override what band the phone connected to, the performance would be abysmal. The fix for this would be to physically change the antenna. If you could do this on your own, you deserve an honorary degree in electrical engineering since antenna design isn’t the easiest thing in the world. Here’s where to start: http://en.wikipedia.org/wiki/Maxwell's_equations
Since there is a discrepancy between the Verizon and HTC spec sheets, I would do the following:
1.) Focus your research on seeing which one is correct by contacting HTC and Verizon.
2.) If Verizon’s is correct, you’re done. Romania’s carriers only transmit LTE on 1800 Mhz (band 3). Otherwise…
3.) If HTC’s sheet is correct, focus on why you can’t detect 1800 MHz. It must be something in your unlock method or Verizon really locked the hell out of the radios for some reason.

Cheers mate, went to an actual engineer that handles repairs here in Romania for various brands and we both decided to make it our own personal project to make this happen a Verizon M8 turned into a Euro version one, ill report back with the results in about 2 weeks. Seems technically it can be done, just needs a some work. Thanks again for the reply though.

Hi Macusu,
Just to remember, I believe the problem is not only related to the antenna itself, maybe there are other kind of locks since, as discussed in the other topic, Here in Brazil and I`m not being able to attach it to 4G 2600MHz (Even if the phone supports this frequency).

Thing is they are waiting for all the tools atm, I mean they don't yet have all the new kits for it, it should be arriving, and the engineer is actually a certified person being one that works in a certified HTC service, so once we get the entire .... kit, he will start working on it toghther with the software engineer and so on, hope that it will all sort out, i did get another phone in the mean time as well, but as i said i will be reporting back.

[Completed] Noob in need of radio/modem flashing information

Hello,
I recently purchased a note 5 duos SM-N9208 from Taiwan. I was led to believe that the device was unlocked GSM, but had EV-DO capabilities. My understanding was that this would work on Verizon's network, because it had both radio chips inside. I was told by Verizon that "there is no approved way" for them to get me up and running on their network. The tech made a point of saying there is a difference between approved, and no way. This leads me to believe that something can be done. I'm wondering if someone would be kind enough to help me out. Phone is running original Rom, unrooted, and is basically useless to me right now, as I'm desperately clinging on to my unlimited data with Verizon. Is it possible to root the device, and flash the modem with Verizon note 5 baseband info? Any help anyone can offer would be very much appreciated.

Hi, and welcome to XDA!
When I looked up the specs on the Note 5 Duos, unfortunately it says nothing about CDMA. Having both "radio chips inside" can be taken two ways, in this case, this phone has the capability to handle two GSM carriers (and in this case, like most dual-sim phones, only the first SIM can do 3G/4G/LTE speeds).
Network Technology GSM / HSPA / LTE
2G bands GSM 850 / 900 / 1800 / 1900 - SIM 1 & SIM 2
3G bands HSDPA 850 / 1900 / 2100
4G bands LTE
Speed HSPA 42.2/5.76 Mbps, LTE
GPRS Yes
EDGE Yes

It seems the only option (if you want to use this phone), is to join a GSM carrier like AT&T, T-Mobile, or one of their MVNO's (like MetroPCS).
Hope this helps.

Thank you, Joel! I'm excited to learn as much as possible from tgis forum. I actually changed over to T-Mobile, and have been good for the most part. The problem i'm having now is related to finding a way to flash the radio to all of their Rf's. I rooted, and attempted to flash the modem and bootloader from N920T, but it failed. I am still having a hard timr understanding why the identical hardware will not accept firmware from different model numbers. Again, very inexperienced, so it may be something very obvious i dont know about. If could offer any assistance, or provide and thread links that may be useful, i wpuld very grateful. Ive been searching nonstop, reading, and still cant seem to find a way.

Well, the hardware (particularly the modem) is not compatible, hance the failed install. You are lucky it cancelled out as you could have had worse problems on your hands.
The way i see it, you will have to wait for other regions for the Note 5 Duos to open up before you get flashing options. I would even question the need for that, if you get a decent range of bands with T-Mo (I am assuming you can get 4G).
If you want to explore further anyway, please check out this thread:

It did, thank you! I get decent service (including LTE) almost everywhere. Problem is, once I get to my.house, I go completely out of service. No call.I no text. It wouldn't be a big deal, but the Taiwanese phone doesn't have a way to turn WiFi calling.

Aha. That and no sign of the 700mHz band (which may not be part of your phone anyway, not just hidden by the current firmware).
Since the firmware would need deep support of Wifi Calling (or VoLTE), as in more than just an App, I am afraid you will have to wait until the Duos releases into an area with that support in their firmware (and hope that, that area's firmware doesn't disable a frequency you use).
Makes scraping all the lead paint[*] off the house the more manageable task, doesn't it?
[*] I really don't know if your house does indeed have lead paint. I am assuming it's coated in something metal, or concrete, which avoids typically high frequency radio waves from entering. I never had that problem with my house (which may be strange, since it was built in the 40's), but maybe creating ways to boost the existing signal may be in order instead.

[Completed] GSM on the Sprint HTC One M7

Alright, this is my first post to my recollection, so Im hoping this gets some great responses.
I own a network unlocked HTC M7, coming from Sprint. The thing is, Im in Jamaica, and im using a local service provider called Digicel. They do have 4G services, but regardless of the band I select I only get GSM. Thats the best it gets to be honest. On WiFi, Im all fine, but once it hits mobile data, I automatically get back to the days of our fore fathers.
I have done some research on my own and found that Sprint apparently provides 4G on their CDMA network. I am not very sure if this phone may have 3 radios as a result, and thats what causes this, but I needed some help. I literally just phoned support (Digicel's), who sometimes doesnt seem to have accurate information easily accessible indicated that Digicel's 4G data is available on their 1900 band. TBH, Im not very sure they are certain, and really and truly I am not either. Can I get some help with confirming if this can be used on other carriers comfortably re the radio config?
and if so, is there anything that can be done to have this use 4G on my network? I already did the *#*#4636 thing and ran through all possible network types. Still having the issue. Running lolli 5.0.1.
