Verizon & T-Mobile Question - Galaxy S 4 Q&A, Help & Troubleshooting

I have a verizon S4 that I want to use on the t-mobile network and was thinking about rooting with the intent of installed a custom ROM. My question is can I install the t-mobile stock ROM on it? if not does anyone have a recommendation on what ROM would be good to install in it?

If the phone is locked to Verizon's network only, then you won't be able to use it on T-Mobile not matter how many ROMs you put on it.

It is not locked, I am able to use a T-Mobile SIM card successfully, it just has all of the branding and I keep getting an "non verizon sim card installed" message. I can make calls and access the internet just fine. It shows connected to 4G LTE

Can't a stock T-Mobile ROM onto a verizon s4.

[Q] N910T on verizon networks

I see the general consensus is that the tmobile note 4 cannot be used on verizon. Is the radio purely software controlled? Could I just flash another baseband and modem?
I did notice when I installed cm12 and inserted my verizon sim I was able to get 4g and data access but not on the stock tmo rom. Voice did not work as well. Is there anything I can do? I dont really want to have to shell out for the verizon version with an unlocked bootloader.
Thanks

Verizon Galaxy S5 no service with tmobile or metro

Before I rooted my verizon galaxy s5 I was able to use ATT sim cards but the phone would not get any service whatsoever with a tmobile sim or metro pcs sim. Everyone i spoke to at least was able to connect to the tmobile or metro pcs network, even if they were having data issues...but I was not even able to get a network signal. Finally, I rooted the phone and am using a tmobile rom thinking that may help. But no luck. For some reason my phone will not register itself on tmobile or metro pcs, Not even to just connecto to the network to make phone calls. I tried 2 different tomible roms and i think an att rom and no luck whatsoever. Anybody else experience this issue? Is there a root function or service menu that I need to access to enable the proper band? Is rooting the phone even going to change anything? Makes no sense how every other verizon s5 out there has no problem connecting to tmobile or metro but I have the only one. Ive scoured the forums and have yet to find any answer....thoughts? Oh, I also tried every APN settings combination imaginable. Even other carriers just because I was getting nowhere with the tmobile and metro APNs.
Quite a lot of your thread made absolutely no sense, so I'm not sure if this will help.
Look for a tar.md5 that contains the stock modem partition for the Verizon S5, and flash it through Odin.
Are you bootloader unlocked? I would just flash a generic klte rom, like Cyanogenmod, instead of flashing an ATT or T-Mobile rom.

According to a few people i spoke with the root for verizon s5 can only accept TW roms. And to clear up anything that doesnt make sense. my verizon s5 will not get any service with tmobile or metro. Works fine with att. So i decided to root. After rooting still no luck. However, before I rooted I was getting no bars at all. After rooting I was actually getting service bars but still would not get any actual service. I tried every APN setting I could find and still no luck. Thats all. I will try your advice as far as flashing the tar.md5 and let you know.

There was a bootloader unlock exploit released - it allows any rom to be flashed. It's been in the top development posts for weeks. Go check that out, and you can flash cyanogenmod.
I actually am in a similiar situation except I am already on CM13 using a previously Verizon S5, I just started Tmobile service yesterday and in general I can make calls but data is rather inconsistent. Example right now when I make it call it falls down to 3g (Normal) but when I disconnect it tries to connect to H+ then 3G but all of them don't supply it data so it just swaps around 3G LTE and H+ and I have to airplane mode on/off to fix it. So this person may still have issues using CM13. I did already go over the APN information with people from TMobile and from post around the web. Does anyone think that flashing the Tmobile s5 modem stuff will fix this?
you just need to get the correct APN settings

I've tried the correct son settings. It didn't work. I used the settings found online for T-Mobile. I called T-Mobile. Non of the settings worked. I flashed back the the stock rom. No joy. flashed a verizon s5 rom again. No joy. I am starting to think that this is the only verizon s5 that won't allow t to register on T-Mobile's network.

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?

Using the AT&T H910 outside of the US. Does that mean I will never get any update?

Using the AT&T H910 outside of the US. Does that mean I will never get any update?
I heard that an active AT&T sim card is required for software or system update. Is it possible that I buy an AT&T prepaid sim card from ebay and use it solely for system update outside of the US?
Yes. As long as you are on an AT&T network. Roaming on another provider will not work. You have to have an AT&T SIM *AND* be on the AT&T network.
The other very LONG way, is to root your phone, and then flash the latest firmware. If you don't want to stay rooted, then you can flash the latest full stock firmware which will take you back to stock.

I have this issue as well, unlocked AT&T version on Cricket, I bought a GoPhone SIM hoping that just putting it in the phone would work, but it needs to be active.
Okay thanks for your replies. I guess there is nothing more I can do about it then.

If using 900ds on Cricket, will cricket push updates or can one use the att SIM trick? Ty

SM-G975U (Formally an at&t) refueses to active on Sprint

Hi everyone, title basically says it all. The phone was fully paid for and unlocked. Formally an At&t phone. I'm trying to use it on Sprint's network as it should support it but however I cannot get it to activate at all. Apparently it isn't even recognized by Sprint's system at all. Any advice?
Is it because Sprint is a cdma network and at&t is a gsm network?
I could be very wrong but I dont believe gsm unlocked phones dont play well with verizon/sprint even though they have all the bands.
Let someone wiser point you in the write direction but probably flashing sprint rom on the phone would probably help. There is a thread in rom section that has you flash the unlocked firmware and then flash carrier firmware. I did this with my att unlocked 10+ and now using as a tmobile device(for carrier stuff).
Take it to a store or call ... they're picky as to letting devices on the network that aren't in their system
Gotta flash the g975u1 firmware on it...
