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] How do I know if my phone can get 4G

It's probably a silly question but I don't know how to check. I bought an HTC One X off ebay, it' s brand new and unlocked (but I can tell it used to be on orange.). I'm currently on O2 but thinking about switching so I can get 4G but I won't bother if my phone can't get it. So how do I know if it can use the 4G network?
Thanks in advance.

Assume you are talking LTE (although the official definition of "4G" was revised to include evolved forms of HSPA).
For LTE compatibility, you have to find the specs for the exact model of One X you have (which may get confusing) and find out what band/frequency of LTE the phone is compatible with. Don't confuse this with the GSM or HSPA bands, you've got to look for the LTE band.
Then you need to find the LTE band/frequency used by your carrier. If the LTE frequencies are the same (phone is compatible with your carrier's LTE network) and the phone is unlocked, it should work.
Keep in mind that frequency/band support is most usually set in hardware. So the phone has to be equipped (in hardware) with the correct band. No amount of radio flashing will change the LTE band.

Thanks for your help. So how do I find out the exact model of my phone?

And therein lies the challenge. Matching your phone to a model number or accurate specs is not an easy thing. Telling us what carrier version or country would be a good start.
Also, be sure to hit the "thanks" button for any of my posts that you find helpful.

Thanks! I'm on O2 pay as you go but I bought the phone unlocked from eBay, it was previously on the orange network. I'm in the UK and I'm pretty sure the phone is a UK model.
I can't find the thanks button on this app but ill be sure to press it when I check in on my laptop

Hi I have been really considering getting the RAZR Maxx HD but I see only Verizon has it on lock, wondering if anyone has tried rooting it to make it usable on other carriers?

Somebody was able to modify the RAZR M's radio to work with the Verizon RAZR HD's to use 3G on AT&T and T-Mobile. See below.

hey man i have the same phone as the pictures u posted, and i really need help getting it to work on the t mobile network and getting atleast decent speeds, do you think you can help me out?

I will post a HowTo for doing the required NV edit for this mod using RadioComm later tonight after work.
This method avoids the need for force loading the QV Diagnostic Port drivers by using Factory boot mode which allows RadioComm full NV read/write access.

The RAZR HD [Verizon variant] is considered a 'global phone' and can work around the world as it does have not only CDMA/LTE radios, (check it out on gsm arena as can't recall at the moment) but also GSM/3G/H+ as well. Thing is Verizon is stingy and have blocked it so it will not work in the USA without any issues, but all you have to do it change a fw settings in the radio. Funny they are as they just don't LEARN, the first time, nor the second or any other following time by just letting the phone be unlocked as sooner or later, we will get it unlocked or rooted. *sigh, Verizon*

[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.

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.
Thank

[Q] EU LTE Bands on a NA N5

Hi, I'm going to pick up an American Nexus 5 in 2 weeks which I'm going to use in Germany.
Unfortunately, I just found out that the American N5 does not support LTE Bands 3,7 and 20, which are necessary to get LTE in Europe.
Now my question is, is it possible to enable those needed bands with a custom radio or is this a hardware issue?
Sorry if this is a stupid question, I pretty much don't know anything about that stuff.
Thanks in advance for your help everyone.
Edit: I looked through this thread: http://forum.xda-developers.com/google-nexus-5/help/lte-bands-nexus-5-t2502574/
but still couldnt find the answer.

This.
Although they technically have the same radio hardware, the radio unit is "factory programmed" differently. We don't know if it is a physical configuration or a firmware one as there is no documentation about this... Which means even if it is firmware, we wouldn't be able to change it. Essentially, physically changing the Radio hardware which is part of the SoC, which is part of the Motherboard is the only way.

Alright thanks a lot. I guess I'll have to live without LTE for now.
