Edit Network Bands on Sprint version - HTC One A9

i compared sprint LTE frequency band with the one deployed in my country using frequency check.com and found out they're not the same, hence i can't register on the network when i choose lte on my A9 :/
i was wondering if there's a way to edit/add the network bands i'm lacking without converting it?
Is there any method similar to this but for the A9: https://forum.xda-developers.com/showthread.php?p=61352157

i managed to run this code ##3282# which brings up the EPST menu and from there i can see what LTE band my phone is exactly running (25/26/41) and their priority 25>26>41 which is clearly not the one i'm in need right now. also i've read that it's possible to get the MSL code using a logcat but don't exactly know how to ?
folks, any help? highly appreciated.

It is build I to the ruu, just convert, it makes life easier, and data backups should be compatible.

i'm trying every kind of possibility and consider conversion as a last one.
UPDATE: i downgraded my firmware and with the help of stifilz i was able to enable DM mode,now it works like a charm :highfive: i used DFS to read LTE bands (results are attached) and they're way more than 3 i activated the band 3 which is what i'm looking for but it only remained on #6828 after reboot and didn't seem to work. i also QXDM as well but it's a lil bit tricky, you have to manually write the right numbers for your bands :/
now, can i just uncheck all the bands, since i don't really need them and leaves only one (band 3)?

after sooo much hassle, i was able to finally enable different lte bands and having them enabled permanently both on 6828 and 6829 but unfortunately it didn't seem to be working which is strange since the chipset is able to handle the band 3 with the AT&T version of the A9, why not on the sprint!!

interesting.. @syntenza you said that you're able to enable LTE Band 3 permanently, but it doesnt work?

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:

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.

I've seen a lot of people talking about changing bands but I have yet to see one person explain how they have changed bands on an AT&T S4. So, would you mind explaining the process for those that might want to try it. I'm not going to use T-Mobile any time soon, but I know a lot of people would be grateful if you would share. Thanks.

Go into service mode, and however you want to do it, get to the root service mode menu.
From there, follow these menu items...
From Root ServiceMode Menu:
- [1] Debug Screen
- [6] Phone Control
- [6] Network Lock
- [4] RAT_FREE_SUPPORITNG ON
~ left softkey menu key
~ back
~ left softkey menu key
~ back
- [7] Network Control
- [2] Band Selection
Unfortunately, this doesn't provide quite the granular control you were maybe expecting... So far, I haven't found a way to precisely set what exact combination of WCDMA/GSM bands you want to use, but this does allow the phone to use all the various bands it actually physically contains.
As far as LTE, there's an even simpler method:
Starting at the root ServiceMode screen:
- [3] LTE
- [2] LTE RF
- [4] LTE BC_CONFIG
From there you can "select" or "unselect" and given combination of specific LTE bands.
As with anything in the service menu, you may brick your device or cause other irreparable damage by selecting the wrong item.
Oh, and these are the only two ways to change bands AFAIK. I'd be grateful if someone can correct me, as it would be nice to be able to select the precise bands for both the GSM/UMTS side and the LTE side of the phone.

The video tutorial just unlocks the ability to use any SIM card. To use tmobile's network, you'll need to enable the specific bands. I did a mini write up of that process in my post a bit further up the thread. A trip to Wikipedia or elsewhere on Xda will help you make sure you're using the proper bands for your area.

Great to hear. It doesn't effect your AT&T HSPA/LTE does it? What I mean by that, if you want to go back to using your AT&T hspa/lte, do you need to go into menu and change the band back to support at&t and etc?
Anyone else has tried it and has been successful with it?

So you have to manually switch back if you want to go back to using att bands, ok. I don't have s4 but I tried something similar with my note 2, but I only get gsm or lte bands, didn't see 3g/umts.

[Q] F350S on AT&T in Ohio No 3g/LTE

I've been scouring the internet trying to find a solution. I've been wanting this for a while. I did my research to figure out which model of the G pro2 worked with AT&T. It arrives and now nothing. I'm only getting G not 3g or LTE. I am a bit new to smart phones. I've tried everything I can think of. Am I using the wrong apn settings? Is there something in the band selection menu I'm missing. I'm at a complete loss what am I doing wrong?
In Dialer 5754#*350# and activate your Bands or 5457#*350#
Still no dice
I've gone into the menu and specifically selected the required bands but still not dice. I went into the lte band selection menu. Is there another menu I should go into?

I have done this I selected bands 17 and 5 for lte and 850, 1900 for wcdma and gsm. In the Band Selection Menu. Should I be doing anything with WCDMA Channel, LTE Channel, WCDMA Security, RAT mode, RRC Version, SMS MO Domain, Service Domain, any specific APN setting what is it on your wife's phone, EF file edit, HSPDA category, HSUPA category, GCF Test, OEM RAD Settings, SKT Auto Test, IRS Setting, CA Setting, LTE 3GPP Rel. VER. or anything else I am missing?
I've determined that my phone is a very good fake
IDK if this is real issue but if some does have this problem and comes up with a solution. Please post it here I was beyond frustrated and hope this problem can be solved for someone.
Try going back to 4.4 and using LTE
Try taking your phone to an AT&T store and explain it to them. They will install a new SIM card and associate it with your IMEI #. Then you will have LTE!

I'm sitting in front of a Tmo store waiting for them to open and see where that goes. Hey guys how's battery life with this device. For what ever reason when I did put a Tmo sim in this phone it got only 3g now the chip was a nano from my nexus 6 using a quality adapter but holy crap I've never seen a phone eat a better like Godzilla. Hell it killed the device in like 3hrs. Although when removing the sim it seems to go normal using just WiFi connection. Very strange device behavior. Does this phone have bad battery life in its normal state? Since I am a huge "Big Screen" fanatic I would probably just get the extended battery from the Japan guys on amazon. Your thoughts?

1. Slecect WCDMA Channel and Slecect Full
2. In LTE Channel Select your Preffered band ( You should Knew your LTE band or ask from Carrier)
3. In Band Selection Select your bands or select automatic
4. In RAT Mode select automatic
5. Check mar APN Edit Function.
You can also increase RRC Version, HSDPA Category, HSUPA Category and LTE 3GPP Rel. Ver. if your carrier supports you can get higher speeds.
Reboot Again

Which band is missing on the N920T from the N920A?

I'm having a hard time finding a definitive answer about which LTE band I'll lose using the tmobile variant on att.
I don't think any, I think both are identical. I am using the N920T with AT&t. I would suggest you consider using DarthStalkers ROM, he was able to pull the AT&T carrier files.
The N920T & A are the same. If you had bought the N920I you might lose bands.
Does anyone know where I can get a band 12 coverage map? I can only find the LTE coverage map which doesn't specify if band 12 is used there

17 and 30 (I don't think the 920t's band 12 will work with AT&T's B17 - even though 12 is a subset of 17 (or do I have that backwards?) Possibly 29 (downlink only for AT&T) - but there's very little documentation on B29, so I'm not sure if the N920A supports it or not.

Could you be so kind as to translate what that will mean to me? I have a t-mobile note 4 here on att and it seems to do fine.. Do you think I'll be so lucky with the note 5?

Band 29 is rarely used by AT&T (only as a downlink in heavily congested areas.) This shouldn't be a problem.
Band 30 (WCS band) is something AT&T _just_ started deploying, but I've never seen it in actual use. In fact, until very recently, none of AT&T's own phones supported it. B30 is really of limited value for general use due to it's propagation (or lack thereof.) Like 29, its probably only used as a supplement to other bands. I wouldn't worry about B30.
B17, however, is a Big Deal for AT&T. That's AT&T's primary "lower frequency" LTE band. Because of the low frequency, it has excellent propagation (meaning it moves farther and through trees, buildings, etc.) They use this band to cover large geographical areas with minimal towers. If you will be using your phone in a non-urban area, B17 is almost essential for AT&T. (My phone spends the majority of the time at my home on B17.)
I haven't heard of anyone with a TMO Note 5 device (without explicit B17 support) attaching to AT&T's B17, but that doesn't mean it won't work. However, Unless someone confirms B17 functionality on the n290T from actual use (and not just what they think), I'd suggest assuming that it won't work.

An informative post if ever there was one indeed.
What app do you use to determine which hand your phone is connected thru? I have found this app "LTE discovery", and it seems my att note 3 stays connected to 5 mostly, or 4 for lte. But then for GSM is doesn't list a band, but appears connected. On her t-mobile note 4 connected to att, she stays on 5, but the GSM doesn't appear to be connected to anything..
We will be almost exclusively in the middle of a city, but as with anything that could change or in the event of a road trip..
Is there a place I can sit and study this information? Perhaps a website with all of this data? Or do you happen to work in the field?
In a sea of noobs, an informed person is a real diamond in the rough - I appreciate your time.

That's a good app to use. I also use my phone's diagnostic menu's, but I doubt AT&T left those enabled on the 'a' variant.[/QUOTE]

Is that with "lte discovery" that she doesn't appear to have any GSM side connection? She most likely does, as that's where voice calls will take place...

Google. Then google some more. If you run out of pages from google, use another search engine. All the information is readily available - it just takes time to find it all.

so i got through all the hoops.. don't have LTE ;-(
it connects to band 4 or 5 when i first come out of airplane mode, but it jumps right back off. stuck on 4g. called at&t for an hour, they said initially it wasn't provisioned on my sim card, but then afterwards they determined it was a problem on my end, walked my thru APN settings and then ended the call.. still no LTE.
do you have an opinion of what i could do?

Quoting me in a thread was enough... didn't have to also PM me...
@TEKHD has a firmware that might work for you. Check it out over here: http://forum.xda-developers.com/tmo...h6-tekxodus-n5-urv1-00-00-lollipop-5-t3201869
He has apparently provided a mechanism that is working for other AT&T users... (probably via loading the AT&T RIL libs.)
I haven't tried this (and I don't even have a 't' variant myself.) On the other hand, a quick search of that thread seems to show that other people are having successes with AT&T sim's on 't' variant devices.
Good luck!
Gary
sorry about the double.
after a precursory examination, idon't see exactly what you are talking about in his thread..
is it a download?

i searched all 114 pages and didn't find reference to any of that.. now i know why search provided no results; there weren't any!
so i need to find the att ril libraries. how will i ever find that.

Maybe that was the wrong firmware... it's something in the TMO dev section. Please search.

i've searched the entire tmo dev section for term "at&t" and there are sparse hits; there is some conversation about CSC for a guy in canada getting his VoLTE working, but nothing on att.

Apparently, you already found it: http://forum.xda-developers.com/tmo...on-1-aroma-t3212091/post63516726#post63516726
This has AT&T RIL's in the update.zip, and from a quick look at the first post in that thread, they are installed based on an aroma installer. Others in that thread claim it works for them. You're using a TMO device on ATT, so you have to expect some level of incompatibility. There are AT&T LTE bands that the TMO device simply doesn't support. It doesn't matter what happens with your Note 4. Different device and different modem.
So, if you want to use a TMO device on ATT, you'll have to make some sacrifices. Most people will find the sacrifices are less drastic using an international version of the phone. For some reason, US carriers go out of their way to ensure their devices are incompatible with each other.

ok this is where i started, by flashing the ATT option for this rom. but that doesn't solve the problem. i'm in the process of clean flashing the tmobile choice like he suggested.
thanks for all your help.
i'm afraid this isn't going to work either. i realize the wife's note 4 may have different hardware, and isn't a good reference.
i can see the thing connect to band 5, then band 4, lte .. but it's in "emergency calls only" mode, then it gives up on that, connects to HSUPA or HSPA+ and that's the last of an LTE connection.
i feel like it would connect if it could, and that i'm having a software issue.
problem solved guys sorry for the large headache..
Solution:
AT&T did not recognize my IMEI as being LTE capable. Because of that, they decline to allow my phone to connect to LTE. My phone would connect to an LTE tower (as in the screen shots a few pages back), but wouldn't receive anything back from AT&T, so it would say "emergency calls only" and then give up after about 10 seconds, and then never go back. Crap data all around at this time.
What you'll need to do is walk into an AT&T store, take a picture of the IMEI off an LTE phone, and then call in and change your IMEI to the phone you found. This will cause the system to recognize your phone as LTE capable, and like magic, you'll have LTE.
I can confirm that I have a tmobile branded unit that attaches to band 17. It isn't as frequently as on my note 4, I'm generally on band 2. With that said I've had virtually no trouble with service. I was initially worried about the b17 issue, but it hasn't seemed to make any difference.

Does it attach to band 17 on AT&T or t-mobile?

Unlocking Band 66/71

Hello,
I haven't posted here in quite some time, but I picked up the Mi Mix 2s (Fantastic device), and the only thing that's missing to make this perfect for me, is the inclusion of Band 71 (600MHz). I've seen on multiple posts about Qualcomm phones having bands unlocked using QDXM and QPST tools. In other tutorials I see that they use an app to calculate the proper NV values, but I can't seem to find one that goes beyond Band 44. Does anyone know of a manual way to calculate this value, or another tool I could use?
Thank you much,
Blimey

I've used NV calculator and LTE Band Calculator on the Play Store.
I found this video. I can't test it until 2 weeks from now as I just started unlocking process. If you test, please let me know if it works.

By taping Lock bands then LTE all of them are checked, is that how it's supposed to be ?
I also don't have the option LTE Band Append...

I checked mine on my other rooted device. It looks like they removed the LTE Band Append option sometime between January and now. I sent the dev an email asking for more about this, I'll keep you posted.
If it turns out to be a paid feature, I think the price gouging is ridiculously too high. It's $50/week! But we'll see.

This was their response. I guess we can't use this feature.
HI
This feature is not allowed to access since it’s not safe to mobile phones. Please understand…
