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.

So I've read a bunch on this from all sorts of sites. I believe this to be possible, but need some help with the technical aspect of this.
I posted in the Thunderbolt section because it is probably closest to the Evo 3d, from a hardware standpoint, and need info on how the thunderbolt is configured.
I can get it activated that is not an issue.
A few questions:
1) How to get the phone talking to the network?
I've updated to the verizon prl, and when I *228 I get the verizon programming prompts, but It won't update programming due to not being activated.
2)Do you think the Thunderbolt radio will work with the Evo 3d?
2a) If not, would it be possible to merge the T-bolt radio code with the Evo radio code to create a hybrid?
3)Settings, would any know the ##3282# settings for the verizon network.
If you could post the non-personal info that would really help. Please exclude MEIDs, phone numbers, etc.
I understand this is difficult, I've also read the posts, "Why not just go to sprint?", I'm not interested in those responses. This is a challenge, and I'd like to complete it.
Dev's what do you know?
The sprint 4g network isn't compatible with Verizon's as sprint uses wimax and verizon uses lte so the radios would be completely different hardware.
In theory since sprint and verizon phone are both capable of useing the same cdma frequencies 1900mhz and 800mhz you should be able to get 3g working
The question becomes why would you want to use verizon if you cant take advantage of the 4g. And also why would you come here insted of just googleing your question
Search this
Activate Sprint phone on Verizon, Altell, etc... Network. - PPCGeeks and it might help
And why wouldn't you post it in Q&A where it belongs or in the EVO 3D forum? I predict a short life for this thread.....
I did post in evo 3d, and it was moved to Q+A. Apparently the dev forums are to advertise Rom, kernals, etc. for the devs. Not actual development.

No, they are to post development. What you're asking is definitely Q&A. Devs do spend time at Q&A. I see them answer questions regularly. What do you think the EVO 3D has in common with a Tbolt?
Aren't they basically the same phone, just with a second camera? Same form factor, processor, memory, etc?

Nope. Totally different CPU. It's running a Snapdragon S3, as opposed the the Tbolt's S2. The memory is the same. More advanced GPU. Faster USB. The screen is a bit different because of the linticular 3D feature. The CDMA radio might be similar. If my understanding is right, he's gonna need to find a ROM from the Tbolt that's been ported to the EVO 3D so that the data will work since Sprint and Verizon use different device authentication for data service. I'm not even sure that's possible since the devices are so very different. If what they say is true, and the Tbolt replacement more closely matches EVO 3D specs, I think finding a ROM ported to the 3D will be easier, or possibly the tools to make it work across networks. As it stands, they just don't have a lot in common.
Well it can be done, just follow these steps:
1. Switch to Sprint
2. Load a Verizon PRL onto the Evo 3D
3. Enjoy until they kick you off in a few months for roaming too much.
Other than that, the only other possible way would be if Verizon added the ESN to their phone list, and the chances of that happening are..... well, zero.
Unfortunately, they do this so you can only get the equipment from either them, or by private seller (ebay,CL) and they can put more cash in their pockets. It may be possible to do this in about 10 years when everything is LTE, as (please correct me if i'm incorrect) the net neutrality laws do not allow carriers to limit the types of phones accepted on the network, and you can potentially switch 4GLTE sim cards between phones of different networks. Unfortunately (again), it seems that AT&T and Verizon are going to be using different frequencies for their LTE networks, so it seems that this idea won't work either. Looks like they win again.

GSM SIM cards aren't frequency specific. So long as the handset functions on those bands it should work. In Europe, Mecha of GSM, carriers cannot sell contract-subsidized phones so the SIM must work regardless of the band the carrier uses. LTE is a subset of GSM, and if the same rules apply, there shouldn't be an issue.
Yes it can be done, but the wimax would be completely worthless and it would require a ESN/MEID clone/donor device which is technically illegal other than a few remote clauses that are often read WAAAAY to loosely. In short, just wait for the device on verizon or switch. IF you really want to do it, there are folks that can step you through it if you google enough.

I'm really looking for a solution to the connectivity issue. I'm not worried about WiMax, just the 3g capabilities. I know I can get it added to the verizon db, and I already have Verizon service. I'm looking for real solutions, not "switch to Sprint".
Loonatik is on the track I'm thinking of. I know I need settings changes that I can make, but don't have the info for.
I'm NOT going to do a ESN/MEID swap, not worth the risk.

Actually, it is possible but not with a phone that uses a SIM to store all the configuration. It uses a different registration method than the phones that do not require a SIM. Besides, any phone not specifically designed for LTE won't support the 4G data anyway.
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.
Background: Work bought me an S4, but they use Verizon...I use T-Mobile. I must solve this issue. (Plus it's been so long that since I've even opened my QXDM/QPST that I almost...almost forgot how to use it, man, I miss it)...
This is more of a running log to potentially help others in their endeavors. This is an advanced topic...by today's standards. There is a LOT you need to know before just jumping in on this...unless you're like me and don't mind bricking a device for the sake of learning...then, carry on.
BTW, As you can clearly tell..I don't do super formatted frilly assed colorful posts...
ONWARD!!
What is known so far:
1. The modem MDM9615m is capable of anything...(Maybe even making you tea).
2. Using either 2009031920090615 or 2010031619780721 as the 16 digit PW in QXDM allows you to use "Software Backup" to backup and restore QCN files...(Both work, only one puts the phone offline)
4. The AWS band method that is floating around here (337_aws.qcn) doesn't work...it actually breaks the phone. (more on that later)
5. Putting your backup on again leaves whichever fields the 337 file had intact...so say you put the 337_aws.qcn file onto the phone, it stops working...however, you restore your backup...and the phone starts working again but all the fields of the NV that were written by the 337 file remain. Though phone functionality is restored.
6. MDK or ME7...doesn't matter at this point...no effect on functionality.
7. Flashing an MD1 modem/NV Backup from a T-Mobile Note II (which also has the 9615 doesn't seem to work...yet)...It actually kills the phone...I'll update when/IF I revive it...
8. You can Odin your modem back...whew!
What needs to be explored:
1. Whether or not flashing (shoehorning) another carriers radio will help (or if it's even an option)...this would probably have to be a regional carrier or maybe an international (non US) carrier's radio. Usually the bigger carriers can tell the manufacturer what to leave out/put into their phone...
2. Which NV Items need to be modified in order to get AWS (maybe even LTE) working.
3. Can a backup of another phone....let's sayyyy a T-Mo S4...be made and dumped onto the i545.
4. What complications are there? Is this permanent, can the phone be put back to "normal"? etc. etc.
5. If, as a last resort, we can edit the current parameters that are in the NV of a stock i545 to simply "reroute" (work with me here)...what bands it uses for which function...(this is the most tedious...but most undoable method...that I can think of....so far).
Troubles I've already ran into:
As mentioned before...after you write the 337_aws.qcn file to the phone it's pretty much set in stone...for now. When this happens, the modem starts boot looping...I'm sure this is due to bad parameters since the 337_aws.qcn file was probably from a 9215, i545 uses a 9615...you will not be able to access it again in QPST/XDM...
You'll have to get into Settings, More Networks, Mobile Networks, Network Mode, and select GSM/UMTS...this will keep the modem alive for you to be able to play with it again.
So far that's it. I've only been able to start messing with this phone in the past day or so...so, I'm sure this thread will be my dumping ground for my progress/findings/ideas...etc. Again, I encourage anyone that wants to help....to do so. I'm always open for collaboration.
This is where I start filtering down and organizing what I'm doing.
I believe that the best course of action right now is to utilize the 9615m radio from a Note 2...and perhaps a ROM from a T-Mo S4...
The main reason is because when you flash the 9615 modem but still use a VZ Rom...it tries to force it into a "WCDMA Preferred" selection. Which as we know...isn't an option in the menu. However, it's still trying...but I think the ROM doesn't know what to do at that point (could be way off here). I'm thinking that there has got to be a specific combination that needs to be used....for example...a Note 2 modem with a Tmobile ROM and NV backup? or that...but with a VZ NV backup...
I'm not a programmer/rom guy, (I'm more RF engineering etc...), so I don't know if there are things in the ROM itself that dictate which options are available and how the modem is used...
More exploration to be done...
Build.prop indicates to the system what network options should be available
Tmo rom looks like the way to go
On these newer phones the modem dictates pretty much everything else network-wise

That's good information....I tried running Paranoid Android but it wouldn't boot and any other rom told me that the device ID was wrong. I'm going to look into bypassing that check and try some more...
It hasn't been fully proven/disproven but it seems that there may be a "hard" block for US CDMA devices to use US GSM.
It can certainly see it but won't connect based on the threads I read.
But I don't think anyone has documented it in thorough detail what has and has not been tested.
Now if that setting is in NV data and can be modified... you may have a shot.
But if it's something hard coded and/or physical (QFuse) it may not be possible.
Q: Would it not be easier to find someone to swap with you? Or sell the device and get a Tmo?

Haha, leaps and bounds! easier, but what's the fun in that? How will we learn what can and can't be done if we take the easy way? Plus...maybe someone runs into a stellar deal and can't afford a full priced S4...they might nab a VZ one for cheap...this could potentially help a lot of people...
This is more to learn than anything...
Any progress?
Any progress with this? I'm in the same boat.
Thats a shame. Would be nice to have found out if a CDMA S4 could be fully used with GSM network.

I've been stalking the internet for weeks to try and see if i can pick up all of T-Mobile's hspa frquencies in my area cause I'm tired of edge and I know the hardware is there i just don't want a brick. would rather 2g over a brick.
I have been on tmobiles 4g network with my i545 for 2 weeks now... I have had zero issues.

HSPA on this divi e. Not LTE.
It makes me confused that band 4 LTE is locked on the phone
I always thought verizon had the open access regulation from FCC and that's the reason all verizon LTE phones are gsm unlocked
in fact some posts indicates it's CDMA unlocked also. Some CDMA carriers use R-uim card such as China telecom,and people were able to insert the ruim and have cdma working.
From this post, it seems verizon only had the regulation on LTE 700 band 17, not AWS band 4?
or is it just because verizon hasn't really deployed AWS LTE yet, so the relative software hasn't been released yet?

just for clarification, Verizon uses LTE 700 B13 not B17. According to Samsung and some other website Verizon S4 support LTE B4 and B13. and according to the guy in this post http://forum.xda-developers.com/showpost.php?p=44206677&postcount=20 he is using or have used VZW S4 on T-mobile LTE.
This is one of the oddest things I've ever run into.
I can put a T-Mobile Sim in the phone and it works almost like it was a Verizon Sim with the exception of needing to switch it to global mode when prompted.
If I stick a GSM Metro PCS Sim that I am currently using on the M919 it wont connect to anything except Wifi.
I hate locked bootloaders.
What about with custom roms?

Sorry that was a typo, yep att use b17 and vzw use b13
Verizon is going to deploy a second LTE network using AWS spectrum in congested areas
Why you guys don't install "android data tool" to be able to enter the *#*#4636#*#* menu so you could set LTE only to see if Verizon S4 pick up T-Mobile LTE?
If you are rooted and have access to write system data you could edit the "sale_code.dat" file under system/csc and change from VZW to SPR, AWS or any other code, so you can have more network mode options under mobile network settings.
Just for some clarification... This is done on Stock Touchwiz rom or is the device rooted and / or rommed and loki-d
Thanks,

So I can put a verizon sim card in my tmobile Gs4?I thought Verizon didnt use sim cards like tmobile and at&t.my tmobile Gs4 is unlocked so basically I just need a Verizon sim card and a Verizon plan. Thanks!!!

I don't think that works that way. Verizon is a CDMA carrier and T-Mobile a GSM carrier. Verizon sim card is for LTE only (LTE is GSM based technology). Voice works over CDMA radio which T-Mobile S4 lack of it. T-Mobile sim works on Verizon S4 because Verizon S4 is CDMA/GSM/LTE capable.

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?

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?
I have the I545VRUOGF1 build. Looking too see if there is a way to enable VoLTE on this phone as Total Wireless (my carrier) is saying this phone won't work after they make the switch on 1/1/20.
I'm having the same problem with my carrier (pageplus). I haven't found any info anywhere about VoLTE for our S4's sadly. That said, I'd like to know if voice will be the only thing that stops working after the change (if they let us keep service at all).
I could suffer keeping a voice app if it keeps my trusty phone going, I can't seem to kill this phone lol
I think yes, IF... Verizon S4 (I545) QGF1 firmware can be rooted/custom recovery.
I don't own an I545 S4. I own a l720 S4. Same hardware, but with a different vendor customized bootloader and chain of trust and CSC. There's quite a few Qualcomm Snapdragon based S4's with the same hardware under the hood, but with different vendor brandings... including the I9505.
(My bootloader allows me to be rooted and have custom recovery.)
I'm not going to give exact instructions or hold anyone's hand, but I'll post a general outline of the steps involved...
First get acquainted with "Service Mode" (Key input Q0) and "IOTHiddenMenu"
https://forum.xda-developers.com/showthread.php?t=2734094
https://forum.xda-developers.com/showthread.php?t=1815580
now would be a great time to make a nv/efs backup...
then LOOSELY go through this guide... remembering that you're wanting CDMA/ LTE (or all) options instead of (just) GSM...
https://forum.xda-developers.com/showthread.php?t=2530610
Great, so now your phone wants to default to LTE, but doesn't really have any bands open.
(Mine had only one band open initially). There's a tool that will open additional bands... (yes, it works on Snapdragon S4's as well)...
https://forum.xda-developers.com/sp.../guide-enabling-additional-lte-bands-t3563474
That "CDMA Tool". Interesting software. I think you can perform nv/efs/pit backups from it as well. (in one of the other modules).. Complicated to get working initially. Windows failed to find the Serial to USB drivers for SAMSUNG_android initially. I had to search windows update through driver properties. Our all important dialer code is *#3424# (I believe) for the USB settings dialog.
let's see... I enabled LTE bands 1,2,3,4,5,7,8,12,13,17,18,19,20,25,26,28,38,39,40
So now we should have full LTE but no VoLTE support.
There's a rom for that...
https://forum.xda-developers.com/galaxy-s4/i9505-develop/rom-stock-rom-volte-support-jio-t3578337
at this point you might need (to add) some LTE APN's... from your carrier.
