Galaxy SM-A500M 4G does not work with new carrier

Hi all,
I own a SM-A500M phone. The phone has unlocked stock rom (original rom is not modified by carrier) and updated trough OTA to android 5.0.2. I know 4g does work in my phone because I could use it with my prior carrier, but I recently changed to CLARO and with this new provider I don't have 4g acces, only H+ and it is really slow and laggy connection.
I know the following:
1) Sim card is a compatible 4g nano sim
2) The carrier CLARO has 4g coverage where I live
3) The phone is not the problem
4) I have tried all the usual FAQS (APN's, select LTE in config, reboot) with no success.
5) The phone's variant is right (latinoamerican brand), so It can't be due to frequencies or bands problems.
I asked for help in CLARO and told me that this has happened amongst users with unlocked phones (that is, rom not modified with CLARO's bloatware), and the solution is to flash CLARO's rom. But the problem with this solution is that CLARO hasn't released android 5.0.2 update (and I think it will never update) and I really like android 5 and wouldn't want to return to 4.4.
So, is it true? Is there a chance to fix this problem with minor tweaks? What is the problem here?
Since I recently acquired this phone, I would prefer not lossing warranty, so rooting and custom roms might not be an option.
Thanks in advance. Kind regards!

You could try to flash their rom and check if it works. Then you can be 100% sure that hardware/chip/network provider are fine. I have the same phone on since last week, but still did not go to get the chip at a movistar office. Maybe you need to activate the chip and they refuse to do it unless you get their rom. Maybe just getting their rom, and then flashing back the updated stock one or a CM or whatev would be enough.

[HELP] LineageOS 14.1 not switch from 4g to 3g

In 7.0 stock the option to switch from 4g to 3g work perfectly, but in LineageOS 14.1 the option is available, clickable, but not working. How can I solve this problem?

Which rom exactly are you running? There are different LineageOS.

And which version? The 20170123 official nightly? I'm on they mentioned nightly and switching works as expected.

Anyone??
I'm in 20170227 and I'm also not able to switch between 4G and 3G.
Where I live we have 4G networks but there's no data traffic, only in 3G.
2G switch's fine, but you can't really use it due to its very slowly speed.
Please help.

I have a XT1625 and LTE, HSPA+, 2G, and EDGE all work fine. T-Mobile, tested on 0227 and 0306 build with both stock and ElementalX kernel.
There may be radio differences between the 1625 and 1640 but I can't be sure as to which bands may or may not be supported. When you installed LOS did you make sure to wipe Data/Cache/System/Dalvik? Make sure you don't overwrite existing ROMs without wiping first.

Well, I guess there are different radio frequencies, not sure, but I know that the XT1641 works in different bands than the indian model, so I guess is the same.
Anyway, I think I found a solution: in settings, you have to go to system perfis (sorry don't know how to translate it to english since I can't remember the equivalent, but is above the Google section) then you tap to edit the one you're using. There you have the option to select the favorite type of network, and you actually CAN switch perfectly to 3G, 4G or EDGE.
Can't imagine why it doesn't work in the "right" part of the settings but, you know, if it works it's good.

Sprint HTC 10 on T-Mobile?

Does the Sprint variant work with Ting GSM (essentially T-Mobile towers) if you SIM unlock it following the SIM unlock tutorials? Or would it require more than that? I looked on HTC's site and its shows the phone has all the same bands for the Sprint version and T-Mobile version. Does anyone have a Sprint version working with Ting or T-Mobile?

I believe it does if you change your cid and flash it to the unlocked firmware. There are threads everywhere on how to do this, make sure to check the un-carrier branded HTC 10 xda site.

I run a Sprint device on T-Mobile. Works perfect with the exception of WiFI Calling which I am currently trying to get working.
Simple way is to unlock SIM NV method, load custom recovery, load latest Viper ROM, on AROMA pick the proper base install MM or N and Choose T-Mobile for carrier and that's really it man. the LTE bands are already all there, reason why I say Viper after the unlock is because other people including me had trouble getting data to work on stock Sprint MM. Flashing Viper solved that beautifully.

The only thing that sucks is you will be missing WiFi Calling which to me was a little annoying. I have tried everything, I went as far as S-OFF (kinda of a waste of $25) installed multiple firmwares (T-Mobile stock with Sprint radio, etc), different rom's, so far nothing, it seems tied to the actual us unlocked/t-mobile radio which as we know isn't compatible with the Sprint variant. On the plus everything else works including VoLTE.

If you ever figured out Wi-Fi calling on the Sprint HTC 10 for T-Mobile, do you remember how and can you tell me?

XT1644, no LTE

XT1644
Currently running with:
TWRP 3.0.2-0-athene
Radio: athene_MPJ24.139-49_radio_M8952_70009.08.03.45R+FSG-8952-03.65
Resurrection Remix M 5.7.4 - 20161016
open-gapps 6.0 mini - 20170311
my order of events:
-get new (to me) phone
-unlocked bootloader
-flashed TWRP 3.0.2-0-athene
-never got root on stock because I went straight to Nougat
-flashed twrp-3.0.3-n4-athene_shreps
-flashed – lineage-14.1-20170306-nightly-athene-signed with open-gapps full
-couldn't get LTE and learned that I needed to flash a N firmware (which is the same as a N radio from what I understand?)
-flashed TWRP 3.0.2-0-athene
-flashed athene_NPJ25.93-14_radio_M8952_70030.25.03.62R+FSG-8952-05.30
-still couldn't get LTE to work
flashed up to my current set up and still can't get LTE to work.
I'm at a loss on what to do next.
I no longer have my stock nandroid (missed place it-possibly deleted accidently) thus I do not have what my build number would have been on stock.
I dont have a preference if I go back to Nougat or stay on MM (get to use xposed) I just want LTE to work.
What should I do next? Any help would be appreciated and thanks in advance!

Strange, i have exact the same setup as you right now. M modem (or radio or baseband, it's the same) and as rom RR M. I have no problem at all.

What are your settings of you are on Verizon? If not where could I find them? I have 2 options for APNs which I am assuming is for the dual sim g4+. Which one would I pick for the single sim? Will it choose the APN I want every time?

I am outside US mate, so i can't tell you that but maybe you can call Verizon and ask them if the issue is on there side? Did LTE work in stock 7.0 that you flashed? Are both your sims LTE? Pick the one which is In slot 1 as the slot 1 sim will support LTE. Have you checked your preferred sim for data connection? What is your preferred network settings?? Have you manually tried registering on your network in slot 1?

I compared my APN settings on my LG G2 and they are the same as in the G4+. Although I am unable to edit my settings in the G4+ like I am in the G2. Also, my G4+ only has one Sim slot but two APN options in settings.

I went to Verizon to activate a new sim card with no luck. Still no LTE. I've tried different radios, different ROMs with no success.
What should I do at this point?
How do I completely start over from the way I got it?
Any help is appreciated. Thanks

Have you tried the hidden menu code: *#*#4636#*#* Open the dialer and enter that code, you will get a hidden menu called "Phone info". About half way down there is a drop down menu, change that setting to LTE only. See if your LTE works then. If it does, change it to LTE/CDMA auto (PRL) (This is assuming you are on Verizon or Sprint or another CDMA MVNO)

If your phone has only one sim slot it should be talking about settings for 2 sim. In the flashable zip thread you will find MPJ24.139-64. Afaik that is a US build only. Also the radio is different it seems (athene_MPJ24.139-64_radio_M8952_70009.08.03.45R+FSG-8952-03.68.zip) Maybe you can try the non-Amazon version? You said you are not in the US but it's a US model, right?

Thanks guys I figured it out(but not really). I started over from the beginning and redownloaded everything and tried again and it took this time. Not sure what I did differently but I have LTE now.
However I am now having a problem with accessing Dialer/calls/settings when trying to set up Google voice. Dialer app crashes and sim reboots. Ugh...
I'm in US with US phone on Verizon and one sim card slot.

I am in the US, mine is the xt1644, is model. The OP is having problems with LTE. I was having problems with LTE - CDMA.
Are you sure the radio you're referring to is a US radio?

I am also having that problem with call settings. You just have to set up call forwarding no answer to go to your Google voice number. I know also the Lineage and or the latest jp25 radio thinks I have two sims.

Google voice is all set up as I've used it for years. I simply cannot get into the settings to change it over from provider to Google voice. Frustrating...

Not sure who your provider is, I think you said you're cdma. I think all cdma provider's use *71{plus your 10 digit google voice phone number} to forward voicemail to google voice.
Here is a link to Verizon's instructions.
I have never been able to set up google voicemail through call settings on any phone on verizon anyway, it just gives you a link to the instructions.
By setting it up with the above method, it will automatically forward all busy-missed calls to your Gvoice number. It will never go to voicemail in the first place.

I guess you are askimg me?
I do can tell you that EU went from .63 M to Nougat and that there never was a .64 here so i started asking people. From what they told .64 (and .64 amazon) are US builds. Still i cannot find any official info, sorry.

xt1644 (us) moto g4 plus radio

I am running Official Lineage for the Moto G4 plus , I currently have the latest radio (M8952_70030.25.03.62R8952-05.30.R), this must not be the right radio for the xt1644 (us) version on Verizon (cdma). It (or the rom) thinks I have 2 sims. The 1644 version has only one sim (a cdma/gsm,/lte, etc. ) radio.
The phone is sometimes flaky, sticking on cdma or LTE, have to go into the hidden menu (Phone info), to get it to switch sometimes.
Also Phone-settings-calls (phone.android.com) always force closes when trying to open that submenu.
Droidphilev said we may need to flash this radio: athene_MPJ24.139-64_radio_M8952_70009.08.03.45R+FSG-8952-03.68.zip
Does anyone have any experience with the xt1644 specifically? I know most of you are in Europe/asia and have GSM.

I'm also running the latest LineageOS and having radio issues, but I'm on AT&T... I'm not sure what version of the phone I have.. Are there any diagnostic tools I can run to look for hints?
