HTC One Tmobile Google Play Edition Radio - T-Mobile HTC One (M7)

Can someone please enlighten me? Is the band compatibility issues on the HTC One GPE a hardware limitation or software limitation?
Reason I ask is that I would like to do a full GPE conversion on my HTC One that I got from T-mobile. If I do this would I still be able to connect to the same towers and have the same signal on HSPA+ specifically? Or would I have to (and be able to) flash a T-mobile radio? Or would I just be screwed?

I'm not sure, but I have a tmo one running Android Revolution Google Edition ROM and flashed a tmo radio and get great reception mLTE and HSPA +

I have the gpe 4.3 radio on my T-Mobile htc one and I'm getting better lte reception than the T-Mobile radio.
I'm running the arhd 4.2.2 Rom.

The Roms you install shouldn't prevent you from connecting to the HSPA network. The HTC One GPE has a physical (radio) limitation that prevents it from connecting to the HSPA because its lacking one of the radios for the frequency TMobile uses for that standard.
If you have a TMobile phone and make it be a GPE via ROM flash, you shouldn't have issues.

Thanks I wasn't quite sure what the limitation was. I couldn't fully convert to GPE like I wanted since I can't get s-off but I'm running ARHD 4.3 with the GPE radio and yep I'm getting even better signal. Thanks guys

What about the Dev Edition working with flashed radio
This may be a n00b question, but I have an opportunity on a sweet deal for a Developer Edition One, and am considering T-Mo for the service. I understand it lacks the HPSA+ 1700 radio, but is that a physical limitation, or can you flash the necessary firmware on top? According to T-Mo, my area of Atlanta is serviced by LTE, so it wouldn't be an issue at home, but I don't know what would happen when I step out of the coverage zone.
Any tips or advice?

It's a physical issue, it does not have a radio that supports T-Mo's frequencies, as much as I'd like one, I can't give up LTE

This post has answered one question of mine being whether the hspa issue was a hardware issue or not. Hkwver I have a normal T-Mobile one that I converted to fully stock gpe with stock boot loader and recovery and ever since making the switch in certain areas I lose LTE briefly cinect to hspa and end up on 3g. Before the switch in these same areas I would never lose LTE connection or suffer speed loss. Since the switch though there are a lot of areas that I cannot connect to anything but 3g. So if this is a hardware limitation the GPE RUU shouldn't effect this manner or is there something in the RUU preventing access to this radio seeing as it was written with knowledge of the hardware it was being placed on not having the proper hardware? Is there anything I can do to restore functionality of hspa while keeping Google play edition on my HTC one ?

I don't have an answer to your question, but I'm trying to figure one thing out - you were able to do a full GPE conversion (including RUU and changing the model ID) to a T-Mobile One and didn't brick it?

no it did not brick the device if fully functional receives ota updates and the questions I had in the OP I've answered. The device gets hspa+ 42 as well as LTE so the issue must be a hardware limitation of the gpe that u can actually purchase. In fact it is a at t model which is why it suffers the lack of HEPA connectivity. However if j flash a T-Mobile over to GPE RUU it will have HEPA+ connectivity. Also mid and Cid do not need to be changed in order to get ota updates. The OP has been edited since this was discovered all u need to do is flash the ruu and you'll have a fully official gpe HTC one with ota.

[Q] Wind vs. TMobile Amaze plus a couple of other questions....

Hey all!
Sorry if this has been asked before (I've seen posts about it but no straight answers on the issue).
I have a brand new T-Mobile Amaze and a brand new Wind Mobile Amaze. Long story about why!
I can't decide which to keep. I like the fact that Winds is unbranded. I would probably like to use the wifi calling feature on the T-Mobile one when I visit the US (I spend 5 months in the US and the rest of the year in Canada). I don't think I want to root this phone....am undecided right now. The thing that bothers me though, is the camera program on the Wind Mobile version. It's completely different and I like the T-Mobile one better. If I DID decide to root, could I get the T-mobile camera on the Wind one? And then, how would wifi calling work?
Sorry, I'm a newb who is not savvy about any of this stuff....
Any help would be appreciated
Also, I read something a while back, that the bands are different between the two versions. Is this true?
Thanks in advance! CHEERS!
I'm no pro and please correct me anyone if i'm wrong but yes. the bands are different, which is why there are different RUU's for the telus, tmos, wind etc amazes.
I'm pretty sure if you kept your wind mobile one and then followed the procedure to root the device, you'll be able to use the ROM's that we have on XDA and then in my opinion that would give you the camera from the T-mobile one (most likely unless it's been changed) - but yeah don't hold me 100% accountable for this.
You can flash a T-Mobile based ROM onto the WIND's Amaze. With this, you will get the camera interface from the T-Mobile Amaze. I'm not sure about WiFi calling since I never use it - actually I don't even know if WIND has WiFi calling on their network.
Keep the t mobile one, wind one is not yet compatible with the kernels supplied by custom ROMs for now. Means anything with faux kernel
I know it says compatible with all the htc amaze on the kernel page but it is not for the Wind
Thanks for the replies
Hmmmm, I may think about rooting after all....I am looking at both the T-Mobile and the Wind site....
T-Mobile Amaze:
850 MHz;900 MHz;1800 MHz;1900 MHz;UMTS: Band I (2100);UMTS: Band IV (1700/2100);UMTS: Band V (850)
Wind Amaze:
3G (UMTS/HSPA) AWS 1700/2100 2G (GSM/GPRS/EDGE) 850/1900/900/1800
They look like the same bands to me. (??) I really like the unbranded Wind one. I'm not sure if I would ever use wifi calling when I had the phone in the US. Could I potentially add the T-Mobile wifi calling to a rooted Wind Amaze do you think?
Thanks so much once again. Sorry for the dummy questions....!
Wind's Amaze bands are (from the box, and I have verified that I could connect to both T-mobile and AT&T bands while in the states):
HSPA 850/1700/1900/2100.
GSM 850/900/1800/1900.
Kernels from Faux do work on the Wind Amaze (at least, they did for me when I was running custom).

I don't know what you're talking about, but Faux kernel works fine with my WIND Amaze.

Your videos work fine after? camera still work???? maybe you have a slightly different variant, but recent batch seems to be incompatible.
Hmmm, now I REALLY don't know what to do! I guess I will keep the T-Mobile one since I have already been tinkering with it...that keeps the Wind Mobile one brand new so I can resell it! I suppose I can be a girly girl and put some swarovski crytals over the darned T-Mobile branding!
Now, next step is to find out how to get the wifi hotspot working. Have been reading up on this. May be easier just to root it.
If I unlock it and use it on Wind, would the wifi hotspot work without rooting it?
Thanks again everyone
if i was you i would keep the wind one ... why? because the tmobile branding is a HUGE turnoff when you are looking at your screen (sorry americans!) They are generally the same device just with no branding, you could push an apk to your system folder or apps cant remember and it should work as long as you have a t-mobile sim card. In canada we do not have wifi calling so it wouldnt working here (duh!) Good luck with your pick! what i would suggest be the breaking point is check if either device has S-OFF if it does you could sell it to a developer (possible a little cheaper so they can start making roms and try to achieve s-off in all other devices.) Good luck with your pick, basically theyre both the same device.

Heya!
Ok, so they are the same device exactly....hmmm. So, wifi calling isn't as a big deal as the camera software. I want to make sure I could for SURE have the T-Mobile Camera on the Wind phone. And if I root the Wind one, I am assuming the start up animation can be changed. The Wind one is lame. T-Mobile one is much better;-)
I am not sure what S-Off is....but can you tell me how to check for that?
Thanks a bunch!

you have to boot into bootloader (by removing battery then - pressing volume down and holding it down and then press power button (you should keep pressing both power + volume until you get into bootloader.) if you install a custom rom like bulletproof or sense 3.5 you will get The new Camera APK and bulletproof has wifi calling included good luck!
I don't know why people keep saying that T-Mobile and Wind are different bands.
You do realize that the reason why Wind doesn't get different phones from T-Mobile is because they use the same bands, right?
If the phone doesn't work on T-Mobile's standard 3g+ network (AWS) it won't work on Wind, and vice-versa.
The only thing you need to worry about it is it being sim-unlocked.
The different RUUs only exist because of carrier customization and locking. Wind's Amaze RUU is pretty much stock without the extra bloat of T-Mobile Apps. But of course, the T-Mobile RUU also has the updated camera function, unlike Wind's.
Also, that's the first I've heard about Wind Amaze's having problems with faux's kernel. FYI my Wind Amaze's camera works fine on faux's latest kernel and NRG's Energy ROM (and xboarder's when I used his). However, mine was manufactured in November, so YMMV.
Actually youre a bit wrong on that, T-Mobile does support 2G network so any phone with 2G bands (such as iphone or galaxy note) will work on T-Mobile Network with 2G Internet Speeds. And the RUUs are made for the carrier specific device so if you want to revert stock always use ur own carriers RUU!
I know, that's why I mentioned the standard 3g+ AWS network. If it doesn't work on the 3g network on T-mobile, it won't work on Wind's Home network which uses the same 1700/2100 band (also why people tend to buy T-mobile phones and use them on Wind's network).
And yes, reverting to stock using the same RUU is a good idea. However, from my experience with Motorola's SBFs, they are interchangable among the same device. Because Wind didn't have a publicly leaked SBF, we've been using other carrier's SBFs without problems when reverting to "near" stock.

i still dont know why tmobile version is the only one that have all those camera features, the wind version of the Amaze have the old camera UI like the sensation does, but im sure there should be a flashable zip for the camera like tmobile amaze version is.
anyone that had the sensation 4g knows what im talking about
i dont know if the same flash zip file from the sensation works or not, im not a pro but i figure it wont cause its made to work with the sensation,
another thing guys, they have a blueray feature for the camera when recording, you guys think it can be port over to the amaze?
If you rooted your phone, I have the tmo camera apk for you.

$50 bounty for LTE solution for TMobile users!

That's right.... I want LTE bad. The entire reason I switched to T-Mobile was for LTE. Now the issue is after the sim is activated, LTE disappears.
$50 Amazon gift card if you develop a fix for this. $25 if you give a solution that works!
Let's figure this out! I can't afford an S4 or htc one now....
I don't mean to sound negative or pessimistic but, the LGOG using T-Mobile's HSPA+ service is pretty damned fast as it is... and yes I'd like it to work on my LGOG since it did work not once but twice with two different T-Mobile SIM cards for periods of time but, if you're in an area serviced by T-Mobile's current LTE rollout then you're also getting HSPA+ service too so...
"How fast is fast?" is the question I end up eventually asking people: how fast do you really need the connection to be for a smartphone? What are you folks doing with your smartphones that requires more than ~15-20Mbps?
Also...
Can anyone that is rooted/unlocked (bootloader) and has a recovery installed boot your device into fastboot mode and see if it shows a baseband listed at all? Mine - which is running the stock JB 4.1.2 presently and using the stock JB AT&T radio shows N/A which makes me think there's something going on in there or I busted something during my multiple flashing phase over the past week or so, I don't know. Here's what mine says presently:
FASTBOOT MODE
PRODUCT NAME - mako
VARIANT - mako 16GB
HW VERSION - rev_10 (16)
BOOTLOADER VERSION - MAKOZ10o
BASEBAND VERSION - N/A
CARRIER INFO - None
SERIAL NUMBER - YADDAYADDAYADDA
SIGNING - production
SECURE BOOT - enabled
LOCK STATE - unlocked
Click to expand...
Click to collapse
Now I'm wondering about two aspects there: the MAKOZ10o reference which could be related to the older ICS bootloader since that was a V10o thing, maybe it was updated and now IDs itself as Z10o, I don't know for sure, and of course the fact that it doesn't show a baseband version at all. I don't particularly believe that's what's causing the LTE to crap out and die but, I can't say for certain.
But I'm interested in seeing if anyone else's device running the stock JB 4.1.2 (mine has been flashed with LGNPST directly, not as an OTA - the device could have been 4.0.4 > 4.1.2 by OTA from the previous owner, I have no idea), and of course I can't say for certain when the LTE just stopped working but it was within the first day of me owning the device and before I ever flashed anything or rooted it so I will say that rooting it didn't cause the LTE to stop working and that was the first step in the flashing I've done since I got it.
Still, it's odd that it works then just stops working and never comes back...

For the most part, it's fast.... But it's line having a Porsche with a speed limiter.... Who wants that?
Mine didn't have lte bone stock. I just rooted mine and booted into bootloader and I do have a line of letters and numbers with the baseband.
Bounty is going to be void unless someone has a solution quick! I put it up on craigslist and supposedly someone is going to buy it. Guess I'll have to fork over extra $ for a One or S4
I'm on T-Mobile LTE has never worked for me (been on it about a week). I get week 4g in town and most the time it wont even load ANYTHING! 2G is garbage...... My fastboot shows baseband version as n/a also. Unlocking the bootloader via freegee simply flashes the nexus aboot image which likely hasn't been modified. Does Tmobile LTE work on the nexus/nexus conversion? I know free also flashes a modified boot image but it simply removes the wallpaper.bin file from the phones bin directory to allow removal of any apps (its checks for videos,apk etc etc). I haven't tried flash the T-Mobile modem in the modem thread (.38 or something?) but I am assuming it also wont allow for LTE? Do these phones share modems with nexus or are they just cross compatible? Does the phone run LTE stock? I'm not familiar with at&t and do not know if they have a LTE band. Is it possible the hardware has just been removed on this model for LTE and those that get it do so without the antenna? I know there is another phone where that is the case but I cant remember which one of the top of my head.

As I just noted in another post, the LGOG is fully capable of LTE service on the T-Mobile frequencies - it's a damned Nexus 4 in a different package, with the same hardware radio and I/we can even run the T-Mobile radio firmware as well. That's not the issue.
The issue is that for many of us it DOES work at first but then the LTE stops working and I/we would most certainly like to figure out why it's happening.
Probably tmo trying to force you to buy a phone from them.

Doubtful considering that's one reason they refarmed their network in the first place, so potential customers could bring their unlocked ATT devices to the T-Mobile network and have great service, LTE included. The "uncarrier" has great pride in that fact and have gone through great lengths to advertise it. The issue the OP is having appears to be LGOG specific as I hadn't heard of or seen any other devices with said issue, thus the bounty.

The reason you guys are losing LTE is T-Mobile is slowly switching to a diff band. And it is one this phone doesn't handle. As they convert towers to the new frequency phones that do not handle all the US LTE bands get left behind.

I hadn't seen any information to back this up, feel free to direct me to the info if you'd like. I find it hard to believe as T-Mobile just refarmed the network to support the same LTE bands as att and are still actively advertising the fact you can bring your unlocked device to their network without issue and with full support. In addition individuals are reporting LTE service that works fine initially then ceases generally after reboot or within a few days. The odds of these bands being changed just as users switch in multiple locations to multiple users are slim to none.

I was told this by technical support when helping a friend that has an e970. Whether it is accurate info I guess is now in question. Sorry if it is not.
Sent from my LG Optimus G using XDA Premium 4 mobile app
No worries in the long run, we just like to make sure people do get accurate info. T-Mobile uses band 4 for LTE purposes, and that'll fall within the 850 and 1900 MHz bands they're refarming aka repurposing from primarily 2G/EDGE network usage towards more HSPA+ access which would also get more LTE support there as well.
And yeah, it's irritating as hell knowing it did work and now it doesn't, very frustrating. It's the only thing I haven't been able to get addressed with this LGOG so far and it flat out pisses me off.
Bounty is OFF! I sold the LGOG and picked up an ATT S4 for $185 off CL! Only slight damage to volume button but other than that clean, not stolen and LTE works! Until I bricked it by flashing the wrong rom but it's in the mail shipping back to me repaired !!
I had it running on Simple and I would mainly get terrible edge a I guess HSPA since it would say 4G sometimes. Didn't get LTE until I went over to AT&T.

[Q] Benefits of converting from T-Mobile to GPE or Developer edition Roms?

Hello. I am Currently running the Stock Kit Kat T-mobile rom. I am S-off and rooted. What would be the benefits or drawbacks of completely converting my phone to either the Google Play Edition or the Developer edition version? I know they don't include Sense, but is that the only difference? Thanks for any information!

The developer does include sense. The only advantage is that it doesn't have any TMO software, and they generally get updates before the TMO ones.
Advantage to GPE is that is gets updates first and has very little software installed.
At the moment I can't recall if either of these has the HSPA+ using the AWS band, maybe someone else can chime in here. Having AWS is why I got the TMO version in the first place.
OK so if I use the GPE version, I won't be able to connect to T-Mobiles high speed network? Man that sucks.

I'm hoping someone else chimes in here, because I'm not positive. The phone will always have the radio for AWS, but the software is not in the GPE or Developer edition.
Even if this is true, it will always work with the refarmed 1900 and LTE. So your coverage may be OK depending on your location.
Looking at the Google Play page, I don't see HSPA+ AWS listed:
https://play.google.com/store/devices/details?id=htc_one
EDIT: But if you have S-Off anyway, why not just flash it and see what happens? You can always flash back to TMO or use a custom ROM.
Yea I might just give it a try. I just flashed the T-mobile Kit Kat update so I'll probably try it for a bit, then switch to the GPE and see how I like it. Thanks for the input.

I apologize if this topic has been covered already, however I am not thoroughly acquainted with smartphones and most of the terminology associated with this topic I do not fully understand yet and am therefore unable to extract the information I need from existing forums. I have a Verizon Rezound that I want to use on the GCI prepaid network. I have followed the instructions in a Youtube video by click4geek called Use any Carrier with HTC Rezound (sorry new user, can't post links) and have also unlocked the bootloader via the HTC website. I now can use the phone over the GCI network for calls and text messaging. I have a twofold question: first, what do I do next--root the phone with a ROM (I read this is the best option for phone functionality and the overheating problem)??? If I do this which ROM would most fit my needs (basic user, just need phone calls, sms/mms messaging, and data)? And second, I have set two APN's via GCI protocol (one for data and one for MMS), the problem is I can access data yet I cannot send picture messages. Any thoughts? Thank you for your help!!!!

I can put some input on the ROM, and somewhat possibly on the APN.
First from what you've said, the over heating problem. That's just a known fact with the rezzy.. look on the bright side, you have a great hand warmer for winter! But, Plain-Andy, CM, or Liquid Smooth would probably suit your needs the best of hand. Do you have a custom recovery yet? You haven't gone S-OFF yet have you? So if you do flash a custom ROM, you will have to extract and flash the boot.img manually from the zip, unless otherwise stated in the OP of ROM.
APN, I don't know very much about.. But I know the rezound got global capabilities with the 4.0.3 ICS update, therefore, if you flash any ROM with the latest update, you should be able to apply them again, but I'm not sure if they would work...

You're correct, I do not have a custom recovery or S-OFF. How would I go about doing those, and are they both necessary?
Thank you very much for your assistance!!!!

A custom recovery is needed to flash any ROM. Or just let alone any rooting/modding. If you have the boot loader unlocked, you should just be able to flash a recovery via fastboot using
fastboot flash recovery (name_of_recovery).img
S-OFF (turns off all security flags) can be achieved via rumrunner. http://rumrunner.us although. Its suggested by a couple of devs, mostly Snuzzo to have a minimum 3 or 4 flashes from fastboot. That's also known for boot images (kernels) and recoveries.
From a custom ROM with S-ON you have to flash the kernel from fastboot. Once you flash the zip in recovery, you have to extract the zip on your computer, but the boot.img needs to go into your fastboot folder. Then flash, similar to flashing the recovery but
fastboot flash boot (name of kernel).img
As for the APN thing though.. All I can say about that is, most AOSP ROMS support different services such as GSM and other companies. It'd probably be specific to the ROM that was flashed. Be helpful to possibly flash and ask OP.

thank you for your help. I definitely need more though *sigh*. I followed the directions for "How to Root the HTC Rezound" on the unlockr website. It included flashing an Amon Ra Rezound recovery and installed a Superuser App on my phone. After I followed this guy's directions, I looked at the comments below the process and apparently Superuser and su apps don't work simultaneously on the Rezound and its apparently not rooted, according to the comments anyway. I think in order to flash a custom ROM I will need a "dummies" guide with all steps laid out for me (with S-on). Is there any such guide? Please excuse my naivety. I know it is very taxing explaining everything at an elementary level.

I wrote a giant 30 step guide once.... Let me see if I can find it. But one, you don't want amon ra recovery... That's for ICS. Newer ROMs need TWRP at least 2.6.X.X but preferred 2.7 or above
Edit: Aha! Found it! This has every single step, step by step. http://forum.xda-developers.com/showthread.php?p=51742399
Start at step 11,12 or 13. Can't really say lol. Or, read the whole post. That's about as clear as it gets. Literally lol
Feel free to ask if there is a misunderstanding.

Awesome!!! Thank you for your help!!! I'll let you know how it goes--if you hear a primal scream it may be me!!
Ok so I flashed both the CM and LiquidSmooth ROMS with success, but had no service with CM and had some service with LS, but couldn't send sms messages or get data. What did I do wrong?

What hboot and radios are you using?
There are often a few steps to go through when using GSM on the Rezound... and they vary based on using stock ROM or third-party ROM. On stock ROMs you have to use a third party messaging app (Hangouts, Textra, Handcent, etc) to get MMS to work since the embedded messaging app is hard coded to Verizon MMS servers. In third party ROMs you sometimes have to do that, but often have to flash a GSM enabler to get data to work properly. Remember that the Rezound isn't tuned very well to GSM, especially if it is used on US carriers, so often Edge, and occasionally basic 3G/HSPA, service is the best you can get with great signal.
Your APNs could be an issue as well, remember you can only have one active, but it is based on APN type field... if you need a seperate MMS APN than used for data/internet, your default selected APN must not contain the MMS APN Type, it would be in a stand-alone one, and the MMS APN must not contain the default or internet APN types, and your MMS APN should be the only one with the MMS APN type.

How do I tell what radios and hboot I'm using?
I flashed a GSM patch I found on the LiquidSmooth ROM page but must have done it wrong because after I flashed it it lit up the backlight in the phone when it rebooted and just had a black screen for a long time. I Tried to just recover through TWRP but the phone continually got stuck on the 4G page on the reboot. So did I do the custom recovery wrong? I'm thinking I'm stuck flashing a custom ROM now and can't restore my phone. What is my best course of action? I love the custom ROMS but if I cannot even get service then that defeats the point of having the phone.
I do have to have 2 APN's, and the default (data) does not contain MMS APN in the Type field, it says default. And the MMS APN Type is "MMS".
Thank you!!!!

Remove battery and reinsert, power up holding VOL DN + POWER... that screen is the Hboot screen, at the top is listed Hboot version, radios, and other pertinent data.
I haven't messed with ROMs in some time on the Rezound, I don't even own one anymore... but the Rez is picky, some ROMs work well on some handsets, and others do not... I am surprised that the GSM patch would bootloop LS, there isn't really much you can do wrong if you are using the current TWRP, just flash and wipe cache and dalvik, reboot and wait. What recovery and version are you using (start it and it should show at the top of the screen). You could also try one of @sun_dream ROM's, his are pretty much exclusive to GSM users. What carrier and frequencies are we talking about here would be good info as well...
2 APNs are fine, although all APN types should be lower case, not sure if that would cause an issue or you just listed it that way in your message... Linux/Android is case sensitive for most things, Camera is different than camera.
I will say again that Rezound is a finicky GSM phone, things have to be just right... some people can get it to work with marginal success, but only a select few people can get it working "great", and with other devices being relatively cheap like the Doogee Voyager, Posh, and Sharkk with 5" screens, 1GB RAM, dual SIMs, and quad core processors being available for well under $100, and some devices, like the Blu Dash, for under $60 it makes little sense to push the Rezound too much even as a backup device. Are you located in the US? The Rezound can easily be sold for less than the cost of many of these devices to people with broken devices stuck in a contract with Verizon, I have seen ones in good condition sell for $100-$130, putting you in the realm of really pretty decent GSM phones like the BLU Studio 5.0 C HD for $130, it is a top rated budget phone.
Sorry I got off on a ramble there... I am not trying to sway you from trying to get it working, you might be able too, just don't set your expectations too high, the Rezound is a great device on Verizon... on GSM carriers not so much... I will continue to try to help you as much as I can .

GCI Communications in Alaska, prepaid SIM I believe is 3G
I do have data access on LS, but the service is worse than I had with the stock ROM, and I still cannot send SMS or MMS. I had to leave the house to get it. I will try flashing the GSM fix again, and there is a build.prop fix that I apparently overlooked in the LS postings. If that doesn't work then looks like I'm on to a different ROM. Does it sound like my recovery is just shot, since it won't go past the "4G" boot screen?
Thanks again! You are the Rezound dictionary I've been needing!!!

I'll look at the other stuff in a bit, at work, I'll reply in the morning, we probably need to try to upgrade radios but I gotta do some research that I can't ATM...
But is this a AT&T or Tmo MVNO, or an independent?

I may be wrong, but it looks like GCI operates it's HSPA and LTE networks in the AWS spectrum... 1700/2100 MHz Band 4, similar to T-mobile, the Rezound does not support that frequency band in hardware, meaning you may only get 2G/Edge.
It is really tough to find any specifics though, I will have to look at their FCC filings, what market area are you in?

So I would only be able to get 2G/Edge no matter what ROM or RUU I could flash? How does this affect the fact that I can't receive SMS or MMS on LS but I can on ICS stock? Or does it? I'm in the Matanuska-Susitna Valley area: Palmer, Wasilla, Houston, Big Lake area.

It appears that way, I will have to look at the FCC filings for GCI in that area and see if they support any other frequency ranges. I don't know about their prepaid plans, but the postpaid seems to have some kind of roaming agreement with AT&T. It's pretty uncommon for prepaid to have roaming capabilities though. I'll look into it more in the morning.

Looked into it a little more this morning, doesn't look good for the Rezound on GCI
It appears they have:
1900Mhz for Voice/Text (GSM/GPRS) and 2G/Edge data - supported by Rezound
1900Mhz for UMTS (3G/WCDMA) data - Technically supported by the Rezound, but it is known not to work in the US
1700/2100Mhz AWS for HSPA/HSPA+ - NOT supported by Rezound
1700/2100Mhz AWS Band 4 for LTE - NOT supported by Rezound
The Rezound is known to support:
CDMA: 800/1900 Mhz (Verizon Voice/3G EVDO network)
GSM/GPRS: 850/900/1800/1900 MHz
WCDMA(UMTS): 900/1800 MHz (850/1900Mhz have been "detuned" from chipset)
HSPA: 900/2100 MHz
LTE: 700 MHz (Band 13 only)
To be honest, information on GCI's wireless network is tough to come by, and their FCC filings are very broad ranging for a wide variety of technologies, not very specific at all. Their website mentions BYOD (Bring Your Own Device) in a few places but gives no specifics, FAQ, or other information on what frequencies are supported. Frankly I am a little stumped on finding out more information.
It appears that anything over basic GSM or UMTS speeds requires a device that supports the AWS spectrum, which the Rezound does not, and even that information is sketchy as although UMTS seems to be supported by GCI at 1900Mhz, which the Rezound "technically" supports, the 1900Mhz band for UMTS/WCDMA and HSPA is known to be "detuned" in the Rezound... to a point where you basically have to be sitting on the tower to get minimal service. Whether this was an oversight by HTC and Verizon, or a deliberate plan to prevent the device from being switched to another US carrier since 1900Mhz data is only used in the US, has been a hotly debated issue.
So what this all boils down to it that you should be able to get voice, text, and minimal data services including MMS, working on the Rezound with GCI, but your service will be extremely slow... 2G/Edge in GSM networks usually run from 120Kbps to 384Kbps, and that is probably the best you will get with the Rezound on GCI.
Sorry I don't have better news for you.
Don't apologize!!!!!!!!!!!!!!!!!!!!!!! I'm grateful for the research and the time you put into helping me!!!!!! If you were in my shoes and stuck with the rezound then would you go back to stock via http://forum.xda-developers.com/showthread.php?t=2509770 (since SMS/voice/data at least worked with ICS), try different 3rd party ROMS until I find one that works with SMS/MMS/voice and data (in hopes of finding a better OS) or try to find a fix for my TWRP recovery-gone-wrong?

I would flash a custom ROM, then go s-off, then go through that procedure. You have to be s-off before you can do that. Honestly, if it was me and I needed to use GCI I would restore to stock and sell it, to be honest the Rezound camera on anything but stock is just marginal by today's standards. On sense roms the camera is much better

[Q] Call issues on my m8

I bough my m8 unlocked from eBay when they were selling them at $300. Ever since I got it, it has had an issue connecting calls. It either takes too ling to connect the call or altogether drops it. If I connect the call, I will sometimes not hear the other person and vice versa.
I have tried SkyDragon ROM but the issue still persists. Anyone with an idea on this?
Thanks

If the problem persists on the stock ROM (as well as GPE), you might have a radio that isn't fully compatible with your local carrier.
Do you know what HSPA (3G) and LTE bands (if applicable) your carrier uses?
Also, you might shut off LTE and see if that helps (not possible on stock AT&T ROM).
Am thinking I just S-Off and flash GPE to see if the problem persists. I am on a GSM carrier, have owned several At&t devices before with no problem at all. Switched off 4G LTE and problem still persists. could the problem be hardware?

Sure, a hardware fault is "possible". But you can't attribute it as "possible" without some more research or troubleshooting.
The fact "several AT&T devices" work on your network is slightly irrelevant. Every device has its own set of specs and band compatibilities. You should verify that your network's bands are supported by this particular device (AT&T version), first of all.
You should also consider if the seller will honor any return or exchange before you s-off the phone (such mods which would almost certainly void any return policy by the seller). But if you are not eligible or interested in returning the device, then yes, trying different ROMs or radios reasonable troubleshooting steps.
