Hi,
i own a HTC One S (16GB) device, am running a custom rom (MaximusHD 10.0.1), Android 4.2.2, Htc Sense 5.0, rooted, TWRP 2.7 recovery, HBoot 2.16, Radio 1.20.50.05.16, Carrier is Tmobile, supercid 11111111 and bootloader unlocked. i recently installed maximusHD 10.0.0 everything works fine expect for the network connectivity, i can only make use of 2G (edge) signal but i can't switch to 3G only. Whenever i switch to 3G only my networks goes off but when i switch back to 2G it works perfectly please i would be glad if you guys can help me out
You have the official Tmo version or an international version of the phone? That rom is for the international version and might not be set up to properly utlilize the bands of Tmo service 100 is the first thing that comes to mind.
Confirmed: International version of One S does not utlilize any of the bands for T-Mobile past 2G / Edge.
From HTC's website:
HSPA/WCDMA:2
Europe/Asia: 850/900/2100 MHz
GSM/GPRS/EDGE:
850/900/1800/1900 MHz
T-Mobile HSPA/WCDMA uses a combo of the 1900 Mhz frequency and a combo 1700/2100 AWS band.
I don't know if I get you correctly but if this is what you mean my device displays either GSM OR WCDMA so that mean I have the official tmobile version
I'm confused...you don't know if your phone came from T-Mobile or not?
My HTC one s is from T-Mobile, pls can help with the situation would really appreciate it
Ok. When you installed the rom, did you also install another radio or firmware package as well? As in the one that was listed in the OP of the rom here: http://forum.xda-developers.com/showthread.php?t=2445392 ? If so, that is probably why. The rom and radio are for the international version of your phone, not the one from T-Mobile. Now, obviously the phone are so similar that the software works on both versions. The only difference is the data bands that are supported for 3g/4g and the radios that interface with those bands. So, if you have never changed your radio like it was suggested in the thread for that rom - change your rom to one based off of T-Mobile software. If you have changed the radio, then flash one for the T-mobile version, and you should be fine. If it doesn't work after that, you'll just want to make sure both the rom and radio are for the T-Mobile version.
Thanks man, I think I messed up my device and a newbies to this time installation things. I actually followed the instructions given in the maximushd Rom, I flash the firmware packages with my tmobile version device. Pls what can I do to fix this I need your help

Are you S-Off?
If so: http://d-h.st/7V7 - It's a large file with the Aroma Installer to let you pick which radio you want. I believe you'd be looking for the T-Mous 1.13 one. If you aren't S-Off - Don't bother with that.
S-On?
If so, you need to re-lock the bootloader and run the RUU (Rom Update Utility) to get everything back on track, then you can re-unlock the bootloader and redo the recovery and rom stuff. http://www.androidruu.com/getdownlo..._10.30.50.08L_release_309489_signed_ICS_2.exe

During the installation of Sense-Radio-Installer-v6.zip i came across where it asking to select either US BUILD.PROPS OR NO EDIT please what does that mean

Hi.
I see that some custom roms include radie versions 17.xx and 16.xx. Does the Radio make a difference? And what king of difference.
Is the radio only for reception and such? I have TELIA 3g (Sweden).
And if I use a custom rom and whant to install update of the same rom builder do i lose everything installed on the phone?
Same question as OP
Hi, I've been trying to search for answers to the same question of this OP. What are the differences between radio 16.x and radio 17.x? I know in most cases we are advised to stick with the 16.x radio, but are there places/advantages to radio 17.x?
been wondering the same thing over here
Well, one thing that's different, which many have pointed out before, is that radio 17.5.xx won't work for my phone (AT&T - unbranded). I'm guessing it has to do with the hardware they are using... The unbranded phones get 850/900/2100 MHz. and AT&T uses 850/1900 MHz, So I'm guessing the 17.5 radio updates unbranded and 16.5 works for AT&T. As to what differences the updates do? We may never know,,, The truth is out there! But Mulder and Scully are retired
Greetings,
Ive lurked on xda for years without ever posting. All problems are solvable with a little research and the help of our mutual friend google
Im on my 4th HTC device, now a OneX+ that was brought into Dubai from Taiwan. Having successfully rooted and rommed all my phones and tablets, I kinda jumped the gun and started mucking around with my phone a bit early, using the rootboot early on.
I attained SU properly, but I had the same problems as others that in HBOOT, the radio was "unknown". Unfortunately I didnt write down the original radio settings, so im not entirely sure what my device is.
Now with the latest CWM, I have a working radio, CWM and AndroRevolution 3.0 working brilliantly. Radio is being reported again as the EU version of .16
However what I wanted to know are the following questions:
1) Just a bit of confirmation; the boot.img dictates the radio, correct?
2) If yes, then is it possible to flash a different radio than the original? If no, then does this mean since my radio is confirmed and everything is working, my current radio _IS_ the correct one?
3) My region and provider has LTE support and my provider says I only need to enable it on my phone. However using the dialcode to access test settings and change through the modes, it keeps switching from any LTE reception back to something with WCDMA. I cannot even switch to GSM/WCDMA/LTE auto. It switches back within 2 seconds.
So what Im trying to ascertain here is, do I possibly have the wrong radio, and if I do is there a way to figure out what it should have been?
The other piece of the puzzle is that despite the unit is from Taiwain, the original language when i switched it on was German, which would suggest it is in fact a EU unit.....
Ive searched through many tools, apps, threads, specs, with no luck in answering the question.... Any help is greatly appreciated.

1. Boot.img is the kernel and has nothing to do with the radio
2. You can only flash different radio versions by either flashing an RUU or by S-OFF. Radio is a security protected partition. FLASHING A RADIO WILL NOT ENABLE 4G ON A NON 4G DEVICE!! The HOX+ Inrernational version is 3G only. So in answer to your question. Yes you can flash a new radio, but no you will never have 4G on an international hox+

I do have S-OFF though, so is there a way to confirm if its the international version? The model is PM35110. Any reference online is always in Asian language, so hard to tell. I suppose international version really means all countries.
Bugger.... I bought this specifically for LTE support... :crying:

How did you get S-OFF? Do you mean an unlocked bootloader? because that's a different thing. Nand protection security flag, remains intact when unlocking bootloader. so write protected partitions like radio remain unaffected. Either way it's not a software issue. Its a hardware issue. The LTE device have different radio hardware not just software, So your device is either LTE ready or not.

Er yes, you are not confused, i am. HBOOT is showing S-ON, so I must have been high on caffeine when I was sure I saw S-OFF at one point. However like I mentioned I was playing with the rootboot boot.imgs early on and I was pretty sure I saw S-OFF then. But incidentally that was also when the radio was "unknown" at that time.
Oh well, Im stateside for Xmas and will give my dad the international version and buy myself a new one.
Thanks for your help

You're doing it so, so wrong.
A quick search of the model number reveals that it's the Endeavour C2. If you have an LTE version it would be Evitareul.
1) Wrong. Radios are flashed separately and are not packed into the boot.img.
2) It is possible but unless you are S-OFF you cannot flash one very easily.
3) The reason why is because your device does not support LTE.

Hello everybody,
My Rogers Lumia 920 (unlocked and pentaband beforehand) was bricked mysteriously overnight and I came across the instructions to unbrick the phone. In my NaviFirm search, I noticed that the Rogers ROMs (releases 1232.2109.1242.1002 i believe) for the RM-820 have disappeared as there are many screenshots of them which were posted a few weeks ago. As a last resort, I flashed the AT&T ROM onto my 920 and I have lost the ability to use my phone on Wind mobile and all other AWS networks. Does anybody by chance have an already downloaded Rogers ROM they could share with me? Are there any other roms for the 920 that don't have the AWS bands disabled?
Thanks in advanced!

I just posted links to the Rogers firmware at http://forum.xda-developers.com/showpost.php?p=36686433&postcount=8 .
However, I hate to be the bearer of bad news, but there are reports of the AT&T firmware fully disabling the AWS bands, even if you re-flash the Rogers ROM afterwards. Maybe the posts I've seen are wrong, so by all means give it a try and please let us know the result. :fingers-crossed:
Good Luck!
Wow, thank you so much!!! I'll try it and let you know how it goes.
You have just made my week
Edit: Yeah, the band is still disabled on the Rogers ROM. CURSE YOU AT&T!
Does anybody know how to do a total clearing and re installation of the Rogers ROM then? A bit of a stretch, but hoping this phone won't have to meet Craigslist or something, I love everything about it minus the fact it doesn't work on my network.
Thanks again!

After reflashing the rogers rom did you do a factory reset? I really doubt that flashing an at&t rom permanently disables the aws band even after the original rogers rom has been flashed again. That would mean the at&t rom changes a very secure low level area of the phone and it just doesn't seem that likely or anything I've heard of happening before...

By factory reset, do you mean going into about and reset my phone? If so, yep, I tried it and it didn't help recover the aws band. Is there any way to access the system root of the phone, or am I dreaming at this point? Thanks!

Yeah that's what I meant for a reset. The only other way I can even think of getting the AWS back is possibly finding a dialer code that would let you select radio bands. I want to figure this out too b/c I have a sim unlocked at&t lumia that I want to flash the rogers rom to so I can get the AWS band.

I really have no idea then... But I'm 99% sure after flashing dozens of phones from different companies that the AWS band is not permanently disabled. We just need to find a way to get it back on. Problem is it's probably going to take someone with more technical skills about windows phone 8 (probably searching thru the root directory) to re-enable it.
someone would need to post the baseband of the rogers model and then you can flash the baseband and get your aws band back.
I read somewhere that all the lumias 920 are the same on hardware side, that they only have different softwares and firmware on the inside; rumor has it that if you could get the firmware and baseband that nokia flashes into the dev phones, you could convert any lumia 920 into a dev phone with anything unlocked.

If flashing the att rom to a rogers phone installs the att baseband (which disables AWS) then reflashing the original rogers rom would overwrite the att baseband with the original rogers baseband (should re-enable AWS) so I don't think that is the issue.

The AT&T baseband seems to stick though, maybe the AT&T rom has another file that has no equivalent in the rogers ROM that's sole purpose it to lock out the AWS band. Hopefully we can get this fixed soon, I'd love to love the Lumia 920, but at this rate, my eyes are starting to turn to the 8x.

I don't think the rogers firmware includes the rogers baseband, as the baseband is the one that controls the radios and frequencies of the handset.
One can install a firmware without a baseband and viceversa

The baseband for my stock at&t 920 with the portico ota is 1.0.202075.3. Someone who has a stock rogers 920 that didn't flash the att rom what is your baseband version? (about - more info) Then we need to compare and see what the baseband is on a rogers phone that has lost the AWS band.

I just updated my phone to portico and it seems that I've got the same baseband as you. Can anybody with a stock Rogers ROM post their baseband? After updating, my phone popped up with a new message when I put in my wind sim. It said "Phone mode changes. Your phone is now in GSM mode." I have no idea if you can change modes or anything like that.
Hey guys, I just wanted to jump in here and say that I'm having the same issues. I have a BUILD Dev phone that was bricked -> flashed AT&T -> flashed Rogers and the AWS band is disabled / vanished.
I've contacted Nokia Experts and was told the only option at the moment was to get me a new phone... and I've been waiting for months, lol. I'm thinking that they're going to send me a standard unlocked L920 without AWS bands but that's a bridge I'll cross when or if I get there... I was also told that the repair center did not have the ability to fix this problem and when I asked for the original firmware I was told they (Nokia Experts) did not have it.
Someone HAS to know what's going on here and how to fix it!
If anyone finds a way to get the AWS band back I'm willing to PayPal them $100. Maybe those with more skill will help if we offer financial incentive?
I'm in the US on T-Mobile for reference.
What we need to figure out first is what the baseband is on a stock rogers 920 that has never had the att firmware flashed on it. If it is different then it looks like you'll have to wait this out until nokia comes out with new firmware that has an upgraded baseband and hopefully that brings back the AWS
What about the base band from a Dev device like mine? If the Rogers would work as a reference point then I'd imagine the Dev base band would work too.
There are several users here with them. I can't provide mine because It's been flashed as I mentioned, but I'm currently running 1.0.202075.3 as well as others in this thread.

Is there a way to port TouchXPlorer to WP8? I think it has access to the system directory on WP7 but I've never actually used it before. That might help us extract the correct baseband.

Actually, ALL Verizon phones are SIM unlocked for the last 5 years or so, and the Rezound is SIM unlocked, although on the stock ROM it will give an "Unknown SIM" warning, it does not affect operation of the device and is just an annoyance.
Two things I see here, first is your firmware is NOT global mode (ie. GSM) compliant on the stock ROM... You are on 3.14.605.13 and need to be on a 4.x.x.x firmware of higher for it to work properly, the correct OTA update for you would be 4.05.605.14 which you can update directly from your version, if your phone is STOCK and UNTOUCHED... but seeing it is already S-OFF, it obviously isn't pure stock.
The good news here is you are already S-OFF, so just find the firmware files (Hboot and radios) and flash it with TWRP, then flash a GSM compatible ROM so you don't get the warning message about the SIM, and happily go about your day.
The bad news here is the Rezound was designed as a Verizon CDMA/LTE phone and not really a global device, so it is a HORRIBLE GSM phone, the GSM radios are poorly tuned and need relatively strong signal to even work. Most people who have tried to use this device as their primary phone on a GSM network leave it quickly due to it's poor network performance.

First, in the stock ROM the message app is hard coded to Verizon, try a different SMS/MMS app like Hangouts or Textra.
The GSM fix is to change the default network mode to GSM, it doesn't magically make GSM work (you will find on a reboot you will probably have to change the network mode again manually)... it makes a couple of prop.build. changes and is safe on ROMs it was intended for, meaning AOSP based ROMs, I don't know what happen if you tried to flash it on a CM or Sense based ROM.
As far as best ROMs go, it is tough for me to give advice since I haven't had a Rez for a long time, and my GSM experience with it was, lets just say less than acceptable. Many GSM only users like the ROMs by Sundream, personally I used Evervolv, Talon, and Liquid Smooth.
I just got a new unlocked AT&T M8, switched over from iPhone. I'm going to be using it with T-Mobile, and I'm still struggling to learn how all this stuff works. So the phone is running on Android 4.4.4 currently, and I want to install a custom ROM on it, but I need Android 5.0. Since I have a T-Mobile sim card, I don't have any OTA updates. From what I understand, if I wanted to switch to a T-Mobile ROM, I'd have to pay $25 for Sunshine, which I'd rather not do. Would I also need to do so to get an international ROM? Also, from what I'm reading, my other option is to use the AT&T RUU from HTC's website to update to 5.0, and then install a custom ROM from there. Is this correct, would that remove my unlock, and are there instructions/recommended readings before I try anything? Thanks for any help.

I just got a new unlocked AT&T M8, switched over from iPhone. I'm going to be using it with T-Mobile, and I'm still struggling to learn how all this stuff works. So the phone is running on Android 4.4.4 currently, and I want to install a custom ROM on it, but I need Android 5.0. Since I have a T-Mobile sim card, I don't have any OTA updates. From what I understand, if I wanted to switch to a T-Mobile ROM, I'd have to pay $25 for Sunshine, which I'd rather not do. Would I also need to do so to get an international ROM? Also, from what I'm reading, my other option is to use the AT&T RUU from HTC's website to update to 5.0, and then install a custom ROM from there. Is this correct, would that remove my unlock, and are there instructions/recommended readings before I try anything? Thanks for any help.

You probably want the T-Mob radio software, so you can enable the 3G and LTE bands used by T-Mob. Otherwise, you will find that the AT&T radio does not give you 3G and LTE in many locations.
In order to flash another carrier's radio, you need s-off, and there is no way around that. Then you need to change the carrier ID (CID) and model ID (MID) to that of T-Mob.
At that point, you may as well RUU to a stock factory T-Mobile software image (not just the radio) and that would be recommended, is it will get you a complete T-Mobile "baseline" phone as opposed to an AT&T ROM with T-Mob radio, etc.
After running the T-Mob RUU, your phone will be "fully converted" to the T-Mob version in terms of software. Others here have converted the AT&T version for use on T-Mob. So I'll try to find one of those threads instead of trying to explain it all again.
None of these mods will change your SIM unlock. That will remain unlocked.

Another point: You can update to the latest AT&T Lollipop software by RUU. And you can flash custom Lollipop ROMs after that. But neither of these will enable the 3G and LTE bands used by T-Mob. So that is why I suggest "converting" the phone to T-Mob stock software instead.
Thanks for the response! Appreciate it. A few more questions, since I'm not sure I fully grasp the concept of radios.
If I first flash a T-Mobile ROM, and then install a custom ROM, is that any different from updating with a AT&T RUU and then installing a custom ROM? Will I still be missing the bands?
If yes, then should I just stay away from Custom ROMs all together? Is this a problem because I bought an AT&T phone?
Thanks again!

Yes it's different the AT&T ruu won't give you the T-Mobile bands. And you can install custom roms if you want but I would reccomend paying the $25 to s-off and fully converting to t-mobile and either stay on stock or flash a custom t-mobile rom

I think your first phrase was intended to read "flash the T-Mob RUU, then install a custom ROM".
The radio is not contained in the ROM, and flashing a ROM doesn't affect the radio in any way.
The radio is contained in what many folks here called the "firmware package" or firmware.zip; and it can be installed by flashing the RUU.
Another thing that will help you understand, is that the phone has something like 36 (or more) partitions. The ROM is just one of those. The radio is a separate partition (as bootloader, recovery, and others have their own separate partitions as well). Flashing one partition, does not effect the others. The RUU is a complete software image that flashes all the partitions to factory stock for a certain carrier version.
You can also flash the radio or firmware.zip manually (without flashing the whole RUU). But my personal recommendation would be to baseline to a fully stock T-Mobile software profile, since you are on the T-Mob network, to make sure every partition plays well together (as opposed to mixing T-Mob and AT&T software components).

I wouldn't say that. Custom ROMs have their place. But a custom ROM will not open up the T-Mob bands. As mentioned, you can only do that by flashing the radio, which isn't affected by flashing the ROM.
After baselining to a T-Mob stock config as I've suggested, you can feel free to flash a custom recovery and flash custom ROMs if you like. But if would be for other reasons than the radio bands; such as performance, customization, debloating, etc..

Basically yes. If you want to be sure a phone works fully on a certain network "out of the box", you should buy the phone that is branded for that network. Otherwise, you should always thoroughly research a phone (not branded for your carrier) before trying to use it on your network.
Luckily for you, on this device the radio bands can be changed in software using the mods I've noted above. On past devices, the band support was set in hardware, meaning where was no way to change it in software. In that case, you would really have some buyer's remorse to deal with.
Ah OK thanks for the responses! I think I'm starting to understand. I did research how an At&t m8 would work with T-MOBILE but I didn't realize i would have to go throw this whole software process to make it work! Anyhow I appreciate the help and I'll buy a Sunshine license when I get a chance. Thanks again!
You are quite welcome.
