Hi all,
I tried searching xda forums but didn't find a place to ask the question. I have Verizon Palm phone 2018 model, but since Palm released this phone as standalone and sells on their website. I wanted to find out if anyone knows where or when can I find a firmware for the device, as I want to debrand it.
Any info about this? Really want to flash my Verizon branded Palm 2018 to an unlocked firmware
There seems to be very little discussion on the Palm Phone PVG100 here on XDA. We should start to see a lot more people on here looking to customize it, since it's a bargain (1/4 retail) as a refurb on eBay. I just picked one up and am curious if anyone has unlocked the bootloader, loaded TWRP, and rooted this thing.
I too am looking for a rom for this. I picked one of these up from verizon, and have been using it on tmobile with no problem, but want to get rid of the Verizon apps and branding.
Also, there seems to be MUCH room for improvement on battery life if the ROM is cleaned up.
It's a really nifty little device, just needs some TLC.
I was able to get to the bootloader via typical ADB commands, but can't locate any kind of ROM dump for these. I'm really surprised there isn't more discussion about these little buggers.
Palm PVG100
Hi everyone
I'm trying to modify my Palm too and it's curious to see that no information nor material is available online anywhere
I've started a new thread:
https://forum.xda-developers.com/android/help/palm-pvg100-pepito-development-t3971141
I was able to do something, but I still need help with what i say in my thread.
Basically I would like to take a full backup image of the device before starting tinkering with it, but I can't figure out how to make QPST software (Qualcomm Product Support Tool) show the content of the eMMC memory...
Anyone's help or collaboration for this project would be appreciated a lot!
Thanks!
We're you actually in the bootloader or recovery? I haven't been able to get into bootloader on mine. Any success unlocking bootloader?

Are you sure you want to use QPST. I have used it before to unlock LTE bands on a watch, but not for anything with the images / backups. I think the progression is unlocked bootloader, twrp compiled and loaded, then root. I also haven't seen the Pepito source code anywhere. Without that I'm not sure you will get far. I think the biggest hurdle right now is unlocking bootloader.
I've tried many root tools, nothing works.

If you do boot into recovery, do not run Emergency Download Mode. You'll have to let the battery slowly die before you can do anything with your device.
Clarifications
Ok, thank you for your comments, guys, I really appreciate it.
Please feel free to correct me at any time, because I might make mistakes.
Just to make things clear:
I don't know exactly what you mean by "getting into the bootloader"; what I can tell you is that I was able to get into recovery and that in Settings->System->Developer Options (I'm sure you know that they are unlocked by tapping many times on the buid number), the Palm PVG100 (Pepito) has a switch that says "OEM Unlocking (Allow the boot loader to be unlocked)"; can you please comment on this?
It's not mandatory to use QPST, any solution is good for me (by the way, ONE OF THE PURPOSES FOR WHICH I WANT TO HACK INTO THE PHONE IS TO UNLOCK ITALIAN BANDS LIKE YOU!), but, as you say, no ROM exists on the web, so we have to find a way to extract the phone ROM and to decompile it (do you agree?).
TWRP doesn't exist for this phone, but, to compile it we need to extract protected files from the phone, right? (Please let me know if you know of a method to compile it without root access, nor ROM files)
In my opinion FIRST STEP IS TO HAVE A BACKUP IN CASE OF A BRICK, BEFORE STARTING TINKERING WITH RECOVERY, BOOTLOADER, PARTITIONS, ROM, FLASHERS AND ROOTING! (No?)
About EDL mode the problem is non-existent, I found out that, while in EDL mode, the Pepito can be restarted 100% of the time keeping the power button pressed for 2 minutes (120 seconds) (you can use a tight rubber band for this or any other trick), please test it
I've just had an idea, which requires strong reverse engineering skills. I have 2 Pepito phones; the first one has the most recent version of the software (1AGN), while the second one has the PREVIOUS ONE (1AGL) (see following link: https://www.verizonwireless.com/support/knowledge-base-221025/ )
This update must be doing something at an elevated privilege level. What if one sniffs what tnis update is doing when I force the update or reverse engineers the package obtained from the mother company as soon as it gets downloaded? Might it have information on how to sign software to make stock recovery ADB sideload fuction accept them? Or maybe provide us with information on how to enable write operation on protected partitions?
Ok. I can answer some of your questions here.
1. You haven't been in the bootloader, I'm not sure if there is one.
2. The OEM unlock bootloader in Dev options doesn't do anything but allow your phone to function (from that image) if you do unlock it. It's a security thing.
3. You unlock bootloader using fastboot commands, but Verizon is known for really locking down the bootloader.
4. I also have 2 phones on the different os versions as you have for a similar reason. I was hoping the root tools (kingroot, kingoroot, etc..) would be able to root one of them. Not the case. Both are solid from the standpoint of using standard root tools. I haven't seen many of them succeed after Android 7.1 anyhow.
5. Are you sure your bands are not already unlocked? Even if you get QPST to unlock the bands, it may not contain any data. So you will need to find another device with those bands unlocked to copy the data from (and that still may not work well). At this point I stopped my unlocking of bands project, as I'd didn't want to make a mistake and cook my brain. There has been very little success with band unlocking unless those bands already contained the data to function. Be careful with QPST.
6. I'm not a developer, so I can't really help with anything you are looking to do, but this is an amazing device and deserves the attention it needs to be rooted for at the very least better power management. Maybe underclocking.

Thank you very much for your post, it sheds some lights on the subject.
Well, you say "I'm not sure there is a bootloader", but bootloader is a mandatory piece of the boot chain followed by any device or computer able to boot operating systems, so every device has one; the device might not have a fastboot interface implemented, which is different...but yet annoying...
Standard root tools don't work, I agree, that's why we are looking for developer or board tinkerers help here
I'm 100% sure those bands are not unlocked, because my Italia Samsung Galaxy S5 sees LTE connection, while the Palm doesn't. Also see Palm specs here:
https://www.gsmarena.com/palm_palm-9290.php
It states:

You can see Italian LTE bands here:

It states:
LTE

Interface
B3 (1800 +)
LTE
B7 (2600)
LTE

LTE
I also contacted Palm support for the bands, requesting to unlock them in the firmware and they told me "Support for those bands is a hardware limitation, rather than something we can control in firmware. Unfortunately, those phones can't be made compatible with some 4G networks."...BUT DO YOU BELIEVE THEM?...
So, yes, I do have another device with those bands unlocked if needed.
With QPST there's no need to be careful until I find a way to make it communicate in read/write with the Palm :laugh::laugh: (just kidding)
Maybe if someone has opened a Palm phone and seen the internal board and knows how to perform electronic tampering, he can tell us what hardware components are involved in LTE communication (I think its embedded in the CPU...Qualcomm MSM8940 Snapdragon 435 (28 nm)...see the following link: http://phonedb.net/index.php?m=processor&id=658&c=qualcomm_snapdragon_435_msm8940&d=detailed_specs ...it states:

So I don't see why it doesn't support Italian bands, it makes no sense to me.
An electronic board tinkerer would help us a lot, possibly shorting some JTAG pins inside, maybe to disable read/write protection and, maybe, enable Emergency Download Mode with COM port in 9006 mode or some Diagnostic modes (not the 9008 mode, which was the only one I was able to achieve!)
)
In this forum where do you ask if you want to ask someone to help you connecting remotely to your phone to do live operations on it, using remote COM port software or remote control software (like TeamViewer) or if you need someone able to tinker with board circuitry?
I'm cooking my brain too and I would like to perform the operations you need too for battery life improvement and for my personal cullture, to possibly become of some help for this community, if someone teaches me these things..

Wow, thanks, interesting documentation!
Excuse me, looking at the FCC documentation, is there a way to find out if the phone hardware supports Italian LTE bands or not? Please explain exactly what information to look at for understanding this.
Thanks!
This signed at the bottom of the fcc page:
This device contains GSM/WCDMA/LTE functions that are not operational in U.S. Territories. This filing is only applicable for 700 MHz MBS, 850 MHz Cell, 1700 MHz AWS and 1900 MHz PCS operations

That is even if it has other bands (and it does have them), they weren't tested by FCC.

So Palm probably told me a lie and the hardware supports other bands
There is one additional thing for which I wanted to gain access to the ROM, to root and to custom ROMs and recoveries. Maybe you can help me with this.
I wrote to Palm company, asking:
Good morning
My Palm PVG100 receives Whatsapp messages only when I tap on the Whatsapp icon to open the application, but it's of utmost importance for my job to receive notifications when the phone is locked and to hear the corresponding sound, like it happens with SMS.
How can I achieve this?
Please tell me all steps in detail
Thank you very much in advance!
Francesco
They gave me a list of useless suggestions:
If you are a WhatsApp user and would like to sync your WhatsApp messages between your Palm and another device, you can use WhatsApp Web on one of your devices. WhatsApp allows an account to be signed into the mobile app on one device and another device on WhatsApp Web simultaneously. To setup WhatsApp Web, visit web.whatsapp.com to get started.

Hi Francisco,
I'm sorry for my unclear response. Are you using WhatsApp on another mobile device, in addition to your Palm?
Have you tried whitelisting the app in the Life Mode advanced menu? Try this out: https://palmsupport.zendesk.com/hc/en-us/articles/360021806871-I-am-having-issues-with-notifications
Then I sent them various screenshots showing the settings under which the problem still occurs; I attach a zip file with all the screenshots to this message, can you please have a look at it and help me with your experience, since Palm is not responding?
The behavior is like Whatsapp service gets killed from the background or notifications are held, because notifications come in if they come some seconds after I lock the screen, but if I wait, nothing comes in
When lifemode is on and screen is off, my assumption is everything is off. If you read the 'whitelisting' in lifemode only allows notifications to work in those apps when the screen is on.

the snapdragon chip will always have all the bands! The only limitation for enabling a disabled band I've seen is 'lack of antennas' no clue exactly what that means, I guess there can be different antenna lengths for different bands. Also as I've seen the lack of data for the bands to operate in qpst
Did you manage to access band data of the Palm in QPST?!
No, I haven't used QPST with the palm. you should try it.

we have two hardware Palm version PVG100 and PVG100E/PVG100EU

I bought a new SX56 from an ebayer and it appears to be unlocked etc. I put my current active Cingular SIM card in it but I get a no signal message after it searches for signal. The device came with xda-developers.com ROM version v1.2 on it. I have tried to switch to all of the different Bandswitch settings with no success. HELP PLEASE!!! ANYONE??!!
What's your RSU version ... you can get it from device info or displayed while booting.
PS: it's very risky to use the GSM menu this way. Check with your operator and select the right band once and for ever.
No signal on SX56
My device info is:
ROM ver: 3.17.03 ENG
ROM date? 05/15/03
Radio Version 6.12
Protocol version 324e4
Seems you have a bit old ROM and RSU ... you better check with one in your area but I see here some people have either TMO 4.01.00 + 6.24 or AT&T 30.09 + A30 and they are on Cingular. The right bandwidth setting is the key factor.
Thanks for your reply. I don't know how to do the updates you refer to. I hate to return the thing because I got a good deal on it, but if I can't use it on Cingular I don't know what else to do with it? Any help would be appreciated.
Doc
You can get the complete TMO update (ROM + RSU) here ftp://tmobile:[email protected]:21
Good luck ...
Hi,
I tried to link and get an error trying to connect. Could you please send it again :?: ? Do you think updating to windows 2003 would be if help? I can download it for free from the Siemens website. I just don't want it to lock the phone or cause any damage!
Doc
The official update from AT&T should be OK ... however, you device is better to be PW10B type (check the rear sticker) these upgrades were made for USA use.
Also, if you are in the Cingular 850Mhz only zone, you wont be able to catch signal, cause none of the RSU's will support this band.... (quite unfortunate for all of us in North America)
Thanks for your reply. I'm not sure of the Band mHz on Cingular. I will try to find out from them if I can. Guess I'm the die hard type but I still want it to work or I'll have to abandon it. Any other help will be appreciated

Quite unfortunate indeed. What are the chances that AT&T will release one in the future to make it compatible with Cingular 850 networks after the merger?
I still think there is a way to tune a digital device to another frequency. AT&T has a deal on these for $99.99 and it was just bought out by Cingular. It would be logical that Siemens has something in the mix an upgraded model, different freq. etc.

That's what I am thinking. I am a Cingular employee so I bought one to put on my ERP but I can only use AT&T and T-Mobile signals at the moment.
I am 100% certain that it is possible to get the device to work on 850, more than likely just restricted in the radio stack.
You are lucky!! I have six phones through Cingular and they have been trying to get me a Treo 600 since December!! I'd prefer a windows based device hence my reason for buying a SX56. I had no way to know it would not work on Cingular. All the ads I see for unlocked phones claim they will work on any GSM carrier with an active SIM card.
Obviously it doesn't work hence my involvement in all of this!!
Doc
It is possible that somebody has got cingular sim to work on 850, if they were in close proximity to a mast maybe the 50mhz wouldnt mean too much and a signal could be acquired, but you would still be using a phone detuned by 50mhz which isnt an ideal situation.
I'm not an expert but 50mhz is a pretty big difference in frequency. The splash over from 800 to 850 or 900 to 850 is pretty big. It probably would not work very well even a few feet away from the site where it functions. Still there has to be a way to to tune one of these to 850mhz.

re: the 850 tunning question, As far as I understand this is a hardware aspect of the radio, thus you can not tune to this freq. This is also the reason AT&T did not brand the XDA II, because HTC would not impliment 850 into the device. You are more likely to see a HP6300 or MPx in this department as they are both quadband phones (meaning 850 implimentation) the real question is, will either of these phones be EDGE enabled? My quess is the HP will but the MPx will not. Reasoning: Rumor was HP was using TI Ref design WANDA. TI make EDGE hardware for phones. TI processor may be in the HP phone. The bottom line is you will need new hardware for 850 or EDGE. Sorry for the bad news, I too would love to be proved wrong. Guess I'll have to pony the dough for one of these two new devices. I really loved my HTC device but if they aren't going to keep up...I have no choice. I still feel the XDA will be a better over all device, but without 850 & EDGE implimentation it's going to fall way short. It's nice to own a Corvet, but if a Honda goes faster...why buy the brand name.

I'm getting depressed. I bought this thing thinking it would just be a matter of sticking the SIM card in and off we go!! I've emailed 15 times, joined three different PDA/Phone forums and learned more about these damn things than I ever intended. Now I have a slow PDA, a car charger, extra case, extra sync/usb cable and it won't work on Cingular which I can't change!!!
HELP!!!
Wallaby from T-Mobile works fine with Cingular
Excuse me if I'm way off base, but I just moved over to Cingular from T-Mobile using an unlocked Wallaby, and it works fine. The only thing I haven't been able to do is to make a GPRS connection.
Myself and many others are interested in unlocking the full potential of the HTC Rezound on AT&T and T-Mobile networks. The closest GSM counterpart to the Rezound is the GSM Evo 3D (same chipset and manufacturer) so I'm requesting someone post/upload their radio configuration. This will hopefully facilitate HSPA+ speeds on AT&T and T-Mobile (where the spectrum as been refarmed).
I'm really just relaying info from this thread, I cannot vouch for the safety of your phone when performing these steps (can someone else???).
1) Download and install HTC Sync, HTC Diag drivers and DFS CDMA Tool (free version).
2) Connect phone to PC and switch it to the DM mode (dial ##3424 then Send).
If ##3424 doesn't work, download "Hidden Menus" from the app store, launch it and select DMCmdBroadcastReceiver.
3) Connect DFS to the first HTC Diagnostic Interface port (not 9K)
4) At the Equipment page check if Extended Build ID / MSM rev is MSM8660. If it's different, you've selected a wrong port.
5) Click Send SPC button to send SPC 000000.
6) Go to NV page, click Read RF, let it finish, then click Save and share the resulting NVM file.
Based on what was said in the other thread, this file is safe to share as it contains only RF calibration data and no serial or phone numbers.
If anyone is concerned about the process (above) damaging their phone I will say that I completed these steps this morning on my own phone and the process seemed pretty benign. I imagine pressing the wrong buttons could screw things up, but as long as you only hit "read" I don't think there's any harm.
Hey Tastywheat, hopefully we can get something going. I just started a bounty in the Rezound General section to get 3G on T-Mobile's refarmed area. I tried an AT&T phone last night that was 850/1900 and actually got 3G confirming my area has truly been refarmed. I tried the Sensation NV posted but still had EDGE so it's defiantly gonna take a lot of work on our end as the refarm doesn't seem to enable 3G on the rezound automatically.
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.

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 .

No problem on the ramble I have had a budget phone but the camera on the Rezound is much much better, and that's the main reason I have a smartphone to begin with. Here's the specs you requested in your earlier post:

Team Win Recovery Project v2.8.1.0
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.
---------- Post added at 09:07 PM ---------- Previous post was at 08:45 PM ----------
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
i have a Droid DNA, s-off, bootloader unlocked, super cid and custom 4.4.2 with sense 6.0. i have 4G on my other phone (HTC One M7) and want to use my sim in the droid. i only get 3G. what can i do to connect to 4G?
It probably doesn't have the bands for your providers 4g
The only LTE band enabled by default on the Droid DNA is band 13.
You will have to enable the other bands to make it work.
1.) Install original factory ROM (You could use another ROM but I don't know how to get to Diagnostic mode in others such as CM11).
2.) Install a custom kernel. I has to be created from source, not stock.
3.) Download and install QPST and QXDM.
4.) Plug in phone, let it install the drivers
5.) Type: ##3424# and then hit send, let it install all drivers. This will take a while, ensure it completes before attempting to continue.
6.) Open a file browser and navigate to the "C:/Program Files/Qualcomm/QPST/bin" folder, and start the program "QPSTConfig.exe" (run as administrator by right clicking).
7.) I had two devices listed under the "ports" tab. Only one mentioned an ESN, it was the SURF9615.
Note: If it isn't showing up already under the "ports" tab, go to "Add New Port". Select the one that has 9k in it. You may have to untick "Show serial USB/QC Diagnostic ports only" to see it.
8.) (OPTIONAL, ***But highly recommended***) Now select the QPST Start Clients > Software download > Backup > Start. This saves a backup copy of your phone's stock NV memory to your computer in case you need it later. (I would also recommend that you write down the original values before you make any changes.)
9.) Again in the QPST Configuration program, go to the "Start clients" tab. Start "Service Programming" program. Select to load your device. Then click "read from device". This will send your SPC program code, which should be 000000. This will allow the next program to work.
10.) Next, run QXDM Professional (again, right click and run as administrator).
11.) Change the "view" tab to "NV Browser".
12.) Go to the communications tab in the menu of QXDM and tick the line that lists your device. Under "Target Port", make sure it lists the COM for the device that mentioned 9k earlier.
13.) Once it has loaded the NV items, go to the line 06828 and click "read".
14.) Click once in the box with the current value (should be 4096), and then edit it to be 0. Then, tell QXDM to "write" the value by clicking that box at the bottom right of the program.
15.) You may now click the box again and change this line to reflect whatever band(s) you want to enable.
Now, do the same for 06829.
Tip: You can calculate your own values for this or download the program called "Qualcomm NV Calculator" (It is free). If you use this program, you will use the LTE Bands Calculation tab. You will need to go to the menu in the top right corner and select "LTE Bands Calculation" and tell it that you want to "Use QXDM Notation" in order to get the right values. Enter the decimal result for the 6828 & 6829 values.
Reboot your phone. It should now have whatever bands you have selected enabled.
I know this looks tedious but literally takes about 30 seconds after doing it a few times.
Note: Other programs that you may find useful are "LTE Discovery" and "Network Diagnostics".
did it a 100 times.. with all the band combinations that i could get out of that program.. still not getting 4G signal.. so i think i won't be able to use 4G.. will stick to the 3G. by the way the bands for Romania are : 3,7,20. in NV the code is : 524356

Sorry to hear that it didn't work. Many qualcomm devices are capable of all bands, but it is possible the DNA is not. I did notice on my device that 4G seems to be disabled altogether when I did this on Verizon. So, maybe there is something I've missed.
maybe we are doing something wrong.. i see that more Qualcomm phones are able to see more lte bands (see oneplus one).. so maybe if we use a CM ROM?? i guess it could be ok, because in Diag (*#*#4636#*#*) after selecting LTE it goes back to WCDMA in a flash.. after unlocking all bands when i select LTE is says no service.. so who knows.
The 4G radio in Verizon phones is drastically different as the frequency is different. It isn't AWS like a majority of other 4G radios. Sadly it might never work without changing the hardware out which will cause major issues.

This may not be completely accurate. This method has been used on several devices it would appear: http://forum.xda-developers.com/showthread.php?t=2291589
Also, if you look down in this post, it appears that some phones require you to manually select that you want to activate the bands by dialing *#2263# (or some variation of this) and then selecting the bands that are desired: http://forum.xda-developers.com/showthread.php?t=1547114
It may* work on the DNA. In the end, this may be a hardware related issue, but is is likely just a software related one (I believe). I honestly believe this is essentially the same hardware as the Butterfly with different radios and software. It is fully capable of using the bands you are wanting. However, this is just my theory and remains to be proven.

Those aren't Verizon variants. Those are phones that were built with AWS in mind. The DNA is a CDMA phone with a few GSM bands built into it because Verizon told HTC they wanted a global phone and told them the bands they wanted and the ones they wanted excluded from the phone. There have been ex DNA and ex Rezound (another HTC global phone for Verizon) users who have tried for quite awhile in trying to get these "magical hidden" radios to work and it all came down to that they aren't there in these variants.
You can search and dig up old DNA and rezound threads from years ago and see the amount of work done.
Edit: Checked the old threads. The GSM bands for the DNA is as below. It doesn't support the 1700/2100 (ul/dl scheme) of AWS LTE as it is missing the 1700 in its radio altogether. The phone would need both 2100 and 1700 in UTMS to allow the correct 1700 up link and 2100 down link connections. This phone just lacks the hardware.
It wasn't made to be a GSM only phone. It was initially meant to be used on Verizon and work on international carriers when going on holiday.

I appreciate your input, but did you read the OP or my posts fully?
If you did, you should realize that I fully understand that the Butterfly isn't a Verizon variant, it is the other way around. I was suggesting that there is a possibility that the phone might be able to unlock additional bands because it is basically the same phone as other GSM variants only branded and modified for Verizon as you can see here: http://www.gsmarena.com/htc_butterfly-5118.php
This has been done in the past with other devices including Verizon devices such as the GS5, LGG3, etc as discussed here: http://forum.xda-developers.com/galaxy-s5/general/how-to-add-rf-lte-frequency-bands-to-t2886059
While, I expect you already know this... It all boils down to the fact that R&D cost money. It's often cheaper for manufacterers to slap the same hardware in a device and modify the software to the liking of carriers such as by limiting the bands.
By the way, if you read the OP you would know that band 4 LTE is useless to the OP because he is trying to the phone in Europe, where there is no carrier using that band. You list the bands that the phone has been approved for, but as I mentioned above but other variants of this phone exist that utilize the bands the OP is looking for and there is a strong chance those variants share the same hardware. As mentioned above, this has been true for many other devices. I researched the topic and never found any conclusive proof that they can't be unlocked, so I felt like it might be worth his/her time to give it a shot since the method I listed is pretty easy and safe.
The Rezound is a much different device. It has no GSM radio. I would never have expected it to work on any GSM network...anywhere...ever. About the only things they have in common are that they are both produced for the Verizon carrier and use (different) snapdragon processors by HTC.
I do appreciate your input.

The Rezound does have a GSM radio. A number of users including myself have used it on other networks. Me personally, I tested it on T-Mobile and AT&T and got edge speeds. You are discussing a carrier who purposely burned out the FM radio in the Verizon M7 so it would not be functional. While you are right, HTC might have allowed the bands be made on the radio, it is highly unlikely. Others have tried. Some have even tried doing NV edits and didn't get it to work. This isn't the first time this subject has come up. The DNA can get some HSPA bands, some have tried to get some HSPA+ to work, some have tried getting 4G to work, one actually burned out his radio doing an incorrect NV edit. It has been tested before. HSPA in the US can only work on the refarmed areas. This has been talked about. HSPA will work in other countries that use the above bands specified.
If you are dealing with a carrier that will purposely tell the manufacturer to burn out an FM radio to force internet music streaming, why wouldn't they tell them to make a special radio for their variant? The reason the SGS5 and HTC One M8 work is because of the processor used, this phone is too old to work.
LTE in Europe
Hi, I live in Europe and in my coutry my carrier provides LTE, I've done the radio change with QPST and QXDM as described in post #3, I've enabled all the bands, but without luck.
I've the latest radio and hboot, tried some build.prop file tweas for LTE as described here, still no luck.
May be it's just a matter of some other setttings in buld.prop, but after many trials I think it has to be the radio, what blocks other LTE bands.
I had a bad idea to flash the radio made for HTC J Butterfly (HTL21), but I'm afraid of it (hardbrick), rather to find out, if it is the radio, what causes the problem and if it is, than figure out, how to edit the original radio (if it's possible).
Have anybody tried edit the radio or just able to read out something useful from it?
Somebody created a custom radio for Samsung devices as described here so I think it could be possible for DLX to.
I have a dreaded Verizon. For the time being, I really only need to alter the radios to tune for Tmobile frequencies. No one seems to advertise or understand this but since the S4 is fully capable of nearly every frequency world wide, and I get next to no signal when on T mobile, I believe Verizon purposely only turned on frequencies that they use.
So, unless someone else has a slick work around for the time being, I will have to figure out a root procedure for this configuration. I looked at this late last year and seemed to be a big hurdle.
King root seems to be inconsistent. What are my options for this?

not possible
sorry
the only way it could work is that if you had a i545 running a MDK which lets you run custom kernels
as of now there is no way to flash non-verizon modems to the device
Mobile Networks> Network Mode>
select UTS/GSM is about all you can do
verizon even remove the service menu that shows the available bands
Wow, Verizon must have done their homework on locking down phones. That boot loader is hosery. I consider this much like the government forcing them to give the keys, but did not say they had to put air in the tires. Without the ability to run or select alternate frequencies, service is a no-go
I am mostly in desktop computers but curious why these phones are not being wipes and reloaded with a new OS from scratch? Why all the work arounds and hacks? What am I missing? Does Android have all this on lock down?

S4 Is a terrible device you would be better off with something like a huawei honor or moto g or moto X
I am curious about your phone selections. My basic needs are only a high end device with good signal, mic, speaker, display, battery life, and memory capacity. However, I really felt I MUST have a phone with SD card ability but I really don't remove it, I don't take many pictures, and probably don't need that feature.
What I DON'T want is a device that is HUGE. I like the size of the S4. T mobile felt sorry for my phone issues and gave me an LG Leon. I simply hate it.
I should mention that I later intend to consider writing some custom apps for basic wifi and blue tooth functions so I want a playground that affords me some latitude.

then the honor x5 is what you want its slightly wider then the s4 5.64 5.53 has sd dual sim dual radio and a factory unlockable bootloader
http://www.gsmarena.com/huawei_honor_5x-7590.php
remember huawei is the OEM for google meaning they designed and manufactured the nexus 5x and 6p
Thank you! I find phone shopping to be rather daunting. I see a lot of developers using the Nexus product but also see a lot of people using Samsung due to all their included gadgets on board.
One thing that may be handy is the IR emitter. Is there a site that compares different products well? I do notice the honor does not get high marks for their display performance.
As well, due to using T mobile, I am unsure on compatibility. I need to know if the boot loader is responsible for toggling certain bands on/off? If I buy an honor for ATT, I assume it will be toggled for ATT frequencies? Since the BL is unlocked, can I toggle other bands to ensure I get the best service possible?

idk why you said the honor doesn't get high marks 1080p ips is pretty dam good
tho I guess some `review sites`
having a 2 or 4k display on your phone does no good if the gpu can't drive it
it will look real pretty but real world performance will suffer
different phones vs different carriers e.g CDMA phone like the i545 verizon s4 can not be used on GSM carriers such as ATT and Tmobile
read here for more info on that http://www.pcmag.com/article2/0,2817,2407896,00.asp
a unlocked bootloader grants you the ability to run custom roms and flash certain portions of the phone that are normally inaccessible
the bootloader has nothing todo with radio bands
the honor or any other factory unlocked phone should work on your carrier without issue
Thank you! I guess my only real requirement in the display is having one I can actually see outdoors! Amazing how poor the screen is on this old LG leon.
Maybe you can help me better understand how the bands are configured and/or locked on a phone? The reason I ask is the Verizon Galaxy S4 is technically capable of all bands that Tmobile uses yet I see poor functionality with it, indicating tome it is not picking up certain frequencies. I made the assumption the boot loader would be isolating the bands? Is this software controlled? Or not at all? Which would leave me wondering.
For reference, the Verizon S4 DOES work on Tmobile though. It holds 4GLTE signal but texts will not go out because I believe Tmobile is using 2G or 3G for that.
The way I assumed this worked is the phone is capable of a WIDE range of bands and frequencies, but the service provider would invoke only certain frequencies that they use?

if its holding lte then all you need todo is change the APN to point to t-mobiles servers (store should have offered todo this for you)
t mobile uses slightly differing frequencies depending on your area you are lucky enough to be in one of the area's that use the higher bands
instructions are here https://support.t-mobile.com/docs/DOC-2090
this will not change the fact that you may or may not get data signal depending on where you are connecting too
I would install textra from the playstore and set it as your mms app it has some over-rides for the apn settings if it won't let you change it via the system UI
alt instructions use the`fast` for lte
http://www.4gtricks.com/2013/04/t-mobile-4g-apn-t-mobile-4g-apn-settings.html
Right now the S4 indicated locked to 4GLTE but signal is -90dbm, 50asu. I tested data and I am able to use it though it is slow. I, however, still cannot send an sms. I am able to edit settings for the APN but have verified all settings are per tmobile specs. Any ideas where to go from here?
In the network modes, I am able to chose, 1) global, 2)LTE/CDMA 3) LTE/GSM/UMTS
I have it on LTE/GSM/UMTS right now. IIRC, the GSM is the 2G/3G for sms and voice?
Is it possible that the I545 is trying to operate on the Verizon 750mhz instead of the 700mhz of Tmobile?

should tell you what band its connecting on
install textra and go into its options and enable the 't mobile fix'
OK, I loaded Textra and LTE recovery. I honestly am not certain of what I am looking at on the LTE app but looks like I am connecting to band 4 LTE. At that time, I could not and still cannot send a text. However, at some point, it switched over to a UMTS connection and I was able to fire off texts normally so I know my APN settings are right and there is something odd going on. Textra did nothing different and there is no setting for tmobile other than a wifi setting.
I have read many other people having this exact problem which hovers around those using a verizon S4 on tmobile and upgrading to 5.0 OS.
What I need to figure out, and maybe an area that would require another thread but I need to learn if I may need to reflash the modem to function properly on tmobile and if that can even be considered on an unrooted, boot loader phone? If not, what are the best options? Just dump the phone and get something else? I read of a few roots on the OC1 platform but not sure on that.
If I knew my efforts would work and I knew what I needed to do to fix this issue, I would. I almost just upgraded to the latest revision hoping for a patch in there but not sure I should do that if I want to root? Is OC1 and above all the same for rooting issues?
you don't even have to root to work around this. you can downgrade modem to MDK build. Then use QPST/QXDM to change item 6828 to value 4096
Sins07, I am very interested in the modem mods you suggest as I also came to the conclusion the modem is the issue.
Would I out of line to ask if you can dumb this down a little for a newbie? You mention downgrading the modem only and was not aware you could do that. Can you explain how this modem issue is occuring and how the modem mods will fix it?
