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.

Radios are not .img files to be flashed, they're in /system/etc

From what I heard, getting the right radio is trial and error.
Was wondering if anyone knew which gave best reception?
My phone currently has 63.18.55.06EU_6.35.06.18 and my reception is just OKAYish.
Also, you need to root to install Radios, correct?
Can we use Telus 850/1900 MHz Radio?
With our Heros?
I would like to "gain" 3G in US
Try using the latest one, 63.18.55.06IH_6.35.08.22.

this one arouses a few questions for me:
which is the latest, 63.18.55.06IH_6.35.08.22 or 63.18.55.06IU_6.35.08.22? the IU one is the last to be available as update.zip, can i download the IH version somewhere in update.zip format?
or are we talking about cdma radio versions here?
I think the question here is do you have a gsm hero or a cdma hero, because I don't think you can flash a gsm radio onto a cdma hero. but seeing as you have the EU radio on it I'm going to assume a gsm hero.
I have the 63.18.55.06IU_6.35.08.22, and it seems to serve me well, but then again i'm in england, you're best option is to flash one of them, test it for a day, flash another and test until you've tested them all, and then pick from whichever gave you the best service. Its a long task, but its the thorough option.

Well, maybe I should been more clear. The IH and IU are the same rom. It can also present itself as IW. I'm not sure what the difference means, I presume it's based on the hardware (which bands/frequencies and such that is used in your particular hardware).
If you look inside the radio image you can find all the strings mentioned.
63.18.55.06IW
63.18.55.06IH
63.18.55.06IU
So I guess the 63.18.55.06I is the version (combined with the numbers after it) and the W/H/U is depending on your particular phones hardware.
The same thing is true for the other versions aswell (at least on my phone).
Short version: I use IU version (as it's named here on xda, maybe it should just be named 'I'), it presents itself as IH on my Nordic Hero.
thx for the clarification, packetlss.
Hy guys i have a big problem and i need advice. i was using some rom ics with 3.6 sense and today it start boot loop then i decided to test this
Team Venom presents: Viper3D 1.0.0 Nightly welcome to the future. installation went great but the problem started there. it can not find any network. i tried full wipe of everything but its the same. it does not let me update radio anymore. everything else works. IT revolutionary shooter_u Xa shio s-off RL, hboot- 1.49.1107, radio - 11.25.3504.06_M, cid is HTC__001
and i am using gsm version
Your cid is HTC_001 right? Well that means your unbranded right? Well that could be the problem. If your not branded with a carrier your not going to get a mobile signal. There's nothing wrong with your phone bro. Since your radios are up-to-date of course it won't let you upgrade. Suggestion: brand your phone to get a mobile network. Hope that helps you.

i will try. how to do that?
That depends on what mobile carriers are in your region. Whichever one you chose, you will have to find the right stock ruu with the carrier you want service from. For instance, If you want Vodafone service you would get a shooterru ics Vodafone (with matching radios) ruu file and flash it through your bootloader. Now please make sure you find the correct one or else you will brick your phone. Now, to verify you are on Vodafone check your cid which should say voda_001 or something like that. Note this was hypothetical scenerio and used as an example. But you get my point. After you find your appropriate ruu and flash it. Call the mobile carrier and ask to activate an account with them to get your phone activated. Just remember that I nor nobody else is responsible if you turn your phone into a expensive paperweight.

i understand but the problem is to find correct cid of this network and the orginal is probably changed. It Vipnet Croatia part of A1. Do you have a suggestion where to look?
Ok after much research, I have reached a deadend. So, let me ask you this, is your cid still HTC_001? Does Vodafone own vipnet? If so, maybe flash a Vodafone cid might work for you? I'll try to keep looking, in the meantime is there anybody you know that has vipnet on their evo 3d that can tell you what their cid is?
last i checked (a couple years ago) vipnet was owned by vodaphone.
he's s-off and should have absolutely no problem downgrading his radio, so this is rather puzzling
also I don't think CID should have any effect on his signal
my best guess would be that since viper3D is sense 4.0 based it doesn't play nice with some aspects of the phone, try flashing another rom/kernel maybe, bottom line if i'm wrong you rule those two out,
hope this helps
Ok just checking because he was asking to write a vipnet cid to his phone and after looking through google I came into that conclusion that he could probably brand his phone with Vodafone. I'm pretty sure there was nothing wrong with his phone just needed a mobile carrier to have an active data signal. Thanks for helping me help him.
Have you tried using a custom apn? In other words: setting up the apn yourself? Had the same problem, i live in holland thoufh

Seriously, we are trying to help you. Your radios have nothing to do with your problem. You have to have an active service on your phone for all these features to work. Based on what you have told us it has to be a no service issue. You have to brand your phone with a mobile provider and contact them to set up an account. You do this by flashing a firmware to get your radios intune with your carrier of choice. I did look all over the place and cannot find a vipnet firmware anywhere. My suggestion is to flash to Vodafone for your region. Cid does not have anything to do with getting service since you are unbranded. When you brand your phone the firmware will convert your phones cid to match with the correct cid to have network service. I hope this helps you. I really hate to see you screw up your phone from not listening to our advice.

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.

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.

Here you go: http://forum.xda-developers.com/att-htc-one-m8/help/installing-tmobile-rom-att-branded-phone-t3069388
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).
grant523 said:

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.

Hello.
I have problem with my HTC One m8 at&t.. I live in Europe in Czech republic and i need band 20 to LTE connectivity, but AT&T not supported band 20. He is locked. I have a question.
Can be enabled band 20 on my HTC ? QXDM and QPST isn't working, because in device menager not found COM of my phone.. I don't know why.
I have Lineage OS with Android 7.1.2 and root (SuperSU).
Please, can you help me ? or i will must buy new phone.
I heard something about the radio flashing, but i was not sure about this.
Thank you

That process won't work on most M8 version (including AT&T). It only works on Verizon and (possibly) Sprint, which are really different phones.

It may be possible to add band support by flashing another M8 version's radio baseband (or along similar lines, probably preferable to flash the full firmware or RUU). But you need s-off and change CID to do this. S-off is only possible with sunshine app ($25 US).
Plus, consider that even with the proper band support, your phone may still not support LTE. Since we've seen that happen in many cases. So the money spent on sunshine s-off may be wasted; unless the phone already happens to be s-off.
