Which Modem Should I flash? - Verizon Samsung Galaxy S III

I have a SCH-I535 (d2vzw).
Bootloader Version:
I535VRUCML1
PDA version
I535VRUCML1 / I535VRUCML1a
Modem Board
MSM8960
Android 4.3 (Verizon with some apps frozen)
Right now I have a Straight Talk card in it that connects to the Tmobile network. is there a Different modem version I should flash to, half the time I seem to not have data or txt. i was in a store the other day and lost service all together.
Suggestions? I think after my Straight talk is up I might just go with the Verizon prepaid.

First, this post does not belong in the development section. You only want to post in the development section if you created something to share for the community. Being that you asked a question, this belongs in the Q/A section. I will get a mod to move this for you.
Secondly, there is no other modem that you can flash once on the TW 4.3 VRUCML1 ota. The way that I understand how it works for a Verizon S3, flashing any modem will hard brick the device as the phone does checks once it boots to ensure the firmware is matching. I would operate under the same belief for Straight Talk. There is only one newer firmware available, and that is TW 4.3 VRUCNC1 and that only brings roaming on a specific carrier in Canada.

Flash Verizon S4 with T-Mobile Rom?

Droid V: 4.2.2
Baseband: 1545VRUAME7
Device Name: SCH-I545
My Girlfriend bought me the new Verizon Samsung S4....not knowing that each phone is "tailored" for the carrier. She used her upgrade for me for Xmas and instead of telling her "i cant use it" and have her feel bad, i would like to Flash a T-Mobile Stock Rom onto the S4.
I currently have my T-Mobile Sim card in the S4, and it actually does work for Voice Calls, but Data wont work. Ive tried configuring several different APNs to it (per T-mobile's website). But i still just cant get Data. I also can not get "wifi calling" because Verizon's Rom does not offer it.
So quick questions:
-Do I need to have Root in order to Flash my Verizon S4, with a T-Mobile Rom. I am assuming Yes.
-Would any T-Mobile, Stock Rom, that works with android 4.2.2 be compatible?
IS IT AS EASY as i am hoping? I am not shy to the Rooting/Unlocking world, so if its possible, i will get it done.
Here is your fix

Sprint S5 over to Verizon Possible?

Well I do have a sprint phone and want to know if I can get it to work with a Verizon Pre-Paid SIM, went to Verizon Website and it says my IMEI is ok for working with that. Went and bought the SIM and it just tells me "Invalid SIM". Any help would be appreciated do I need to unlock it? Flash It?
Flash it but it'll only be 3g not 4g,even if it read sim it won't get lte, i flash phone for a living
Sent from my SM-G900R4 using XDA Free mobile app
I guess my question is the towelroot won't work because of my firmware version so I need to do the odin, but it says to use CF-Auto-Root do I use the firmware version I have for Sprint, or download the firmware version to verizon I want?
this is almost exactly is what i'm trying to figure out, just in reverse, because i can get a good local S5 VZW but SPR use different LTE bands.
i know typically the saying is never flash anything for a different carrier of your model, but some people seem to do it with a ymmv statement.
i've read several threads from people talking about carrier rom swap, some casually saying sure it can work, but no updates from OPs or others that said they would try, definitively saying that it worked or failed.
so... has anyone literally gotten something like the Odin flashable firmware at sammobile or someplace for the Verizon VZW sm-g900v and flashed it with the Sprint SPR sm-g900p stock firmware, completely changing its baseband, modem, everything so it now identifies and works the same as a Sprint phone?
or should i just keep waiting for another similarly cheap S5 bundle in a Sprint flavor?

You can find Odin flashable firmwares at sammobile.com. I'm guessing you'll lose root, but you can always re-root with Chainfire Auto-Root. You're well passed any warranty, so don't worry about KNOX or the triangle (since you can use Triangle Away for that).
You should also look into custom ROMs, either custom AOSP (based on stock Android) and customized Samsung ROMs. That way you're not stuck with Verizon's crapplications.
One possibly easier fix is to create a new APN. I don't know if this is doable with your device's version (I imagine it is) though, since I don't happen to have a Samsung running ICS. But if you go to the APN list in settings, look for a + button, and you can create a new APN. You might have to reselect it after a reboot.
Regardless of what you end up trying, you won't lose your carrier unlock. SIM lock is stored in a different part of the firmware and once you're unlocked, you're forever unlocked.

Convert SM-G930T to SM-G930A so I can use AT&T LTE bands.

Hi All, I want to continue using my AT&T prepaid plan but I recently bought a locked T-Mobile Galaxy S7 SM-G930T (I'm going to try to unlock it - if that doesn't work this is all moot). I would like to flash AT&T firmware so I can use the AT&T LTE bands. Can I follow the instructions in the link below once I've unlocked a T-Mobile SM-G930T and turn it into a SM-G930A?
http://www.droidviews.com/nougat-firmware-on-att-galaxy-s7s7-edge-sm-g930a-g935a/
I've read the link below... but it seems to be only if you want to continue using T-Mobile service which I don't.
https://forum.xda-developers.com/tm...w-to-flash-att-nougat-to-t-mobile-s7-t3553610
Changing firmware doesn't have anything to do with what bands the hardware supports. Unlock it and throw the ATT SIM in. Only difference is carrier supported features and software (wifi calling, etc). Flashing ATT modem might improve coverage but all S7 support the same bands.
Thanks buddy for the reply. I'm used to using a custom ROM on my Android phones so this is new. Mostly CyanogenMod.
That's good to know I don't need to flash in order to get the bands but I understand I need to if I want OTA updates from at&t. It seems relatively simple that you just flash the AT&T ROM over the T-Mobile with Odin and then use some update file. It doesn't even effect Samsung pay and Knox which is great.
Stupid question: is the AT&T modem included with the AT&T rom? Also, with regards to the 2nd link in the OP what is the update file that you put on the sdcard to use in recovery - is that an OTA update because your ROM is different from your carrier?

The following is the latest G930A Android 7.0 firmware file. All you need to do is flash it with Odin's AP slot to completely convert your G930T to a G930A. No other steps or files are required: G930AUCS4BQC2_CL10280464_QB12904132_REV02_user_low_ship_MULTI_CERT_meta.tar.rar

I don't get why you would do this other than to have ATT bloat over TMO bloat (IMHO TMO has less bloat than ATT). There's no technical advantage. Am I missing something?

The amount of bloatware is irrelevant since you can freeze all bloatware on either build. I experienced many issues on the TMo version including issues with Android Auto, Google Assistant, and Tasker. I thought these apps were buggy but all of those issues were resolved on the AT&T version. The AT&T version seems to be a better, bug-free build.

Read that in a different thread you posted to after I responded. I think it's very YMMV though. But if you saw improvement then ??
Hi, did anyone ever complete this flash from SM-G930T to SM-G930A? I'd like to do this solely to try and get the wifi calling feature since my workplace has poor cell service but great wifi. I bought the T-Mobile phone, unlocked it, put the ATT sim in and everything but wifi calling works fine. I appreciate the reply!
This is much later in the year (11-8-2021) and ATT has posted the list of phone they say will work and it only shows G930A. It seems their test of working means it must have been sold by ATT. They say My G930T won't work. So Will ATT continue to use customer's unlocked phones it they were not orginally sold by ATT. They have the records. Will ATT refuse to use one of their SIMs even if the phone is Flashed to ATT logo. I do not want to throw away my G930T phone.

Hello and thank you. You posted this information and link back in 2017 and so much has changed. Mostly ATT is now working hard to get rid of all 3G towers and firing up 5G. They said my Galaxy S7-GM930T would not work so I think they link you posted will help me convert the phone back to a GM930A or U or U1. My question is,..Has anything in your post changed since 2017 and if so could you please advise me of what I need to do. Thanks very much.

As of this writing (11/29/2017) this is the latest firmware for the G950U1 att unlocked S8 . I'm leaving this here for reference so people can return to it if/when they need it.
Download, extract, remove .md5 file name off the end of each file, flash.
G950U1UEU2AQK2 (This WILL update your bootloader so after this, no going to QH3 or before. Not that you'd have a reason to)

If I flash unbranded FW on a carrier specific device, loke tmo or att for example, would it sim unlock the phone?
If I flash tmo FW on an att s8 would it in turn allow me to use the att original device on tmo? I ask these questions because I feel like it would work for both my questions since flashing the FW flashes both boot, kernel and baseband/radio. The which is needed for signal. Just some theories but would love to know the answers.
Btw, I have a F model S8+ and was planning on buying some US branded devices so I was curious.

No, it will not unlock the phone (Note: Verizon phones are factory unlocked and remain that way after a firmware flash)
Yes, you can flash any carriers FW to a US S8 and use it with a different carrier.
So I understand, your saying if I flash att FW to a T-Mobile s8 I can use it on tmobile? If that is the case, to me that's an unlock of sorts tiny book lol. Just wanna make sure is all

You can flash att firmware and use it on TMobile but it will still be locked to TMobile. Just running att firmware.

Just realized the typo.....what I meant was, if I flash ATT on a TMO variant I can use ATT while locked to tmo? I'm very unfimiar with combination fw and always opted for the UK models for alot of reasons. Sorry for the confusion of my op question. I know on the s7 and edge if you flashed the US unlocked firmware it not only removed AOL bloat but it unlocked the device. So that is why I ask.

I had a TMobile S7 edge and flashing unlocked firmware never unlocked the device. That's handled by TMobile servers so...
Flashing unlocked firmware will give you just that. The smoother, bloat free firmware from another device but not the actual sim unlock.
I bought an unlocked device and wanted wifi calling so I flashed the g950usqs1aqf7 att firmware with Odin and it worked to enable wifi calling but I'm unable to get any ota updates and I hate the bloat. Is it possible to get WiFi calling with an unlocked firmware like this one? Also what is the difference between the U and U1 firmware variants?

There are plenty of threads on this, but I don't think anyone was ever successful. I flashed att Oreo to my u1 and got the options, but can't get my company to change my imei back.... My personal phone sim works fine. Quit at that point since it's an Ims registration error. You can try merging the wifi calling apks, but I'm pretty sure it's baked pretty deep in the os. The Verizon guys got some of it working. You can try their threads and see if any of it applies to us.

Thanks. Some threads made it sound possible but inconclusive. I'll just assume it doesn't work.
BTW, can you link to the att oreo fw? And what do u flash that with Odin or comsey?
The thread right below this one entitled Oreo ota has all the details and it needs to be side loaded through adb. Not Odin. But you will need to Odin the 950u base to get off u1

Ok thanks. I need to flash anyways because I'm having terrible battery issues and just debating whether to go to a newer version of 950u or back to U1 and losing WiFi calling. In your opinion is oreo beta worth it
So just to confirm, I have read everything, but I am just a bit confused. If I flashed the unlocked firmware via modified odin on a locked AT&T S8 it will remove a lot of the carrier bloat and give my my wifi hotspot back, but remove wifi calling. Similar to when I flashed the T-Mobile firmware on my AT&T S7 and got rid of a ton of the AT&T bloatware but was able to activate my wifi hotspot but lost wifi calling. I stay locked to AT&T which is fine that is not my purpose for flashing

The links don't work. Any chance you've still got the firmware? I've been overseas since october. I have an unlocked AT&T phone that I intend to keep using when I get back, so I want to keep it AT&T FW.
Hi.
I have a G955U Galaxy S8+ AT&T Factory Unlocked on Android 7.0
Baseband Version: G955USQU1AQD9
Android Security Patch Level - April 1, 2017
I no longer live in the US, and currently in the Philippines. Phone works great and the signal is too and all, but I cannot get OTA updates.
Can I just download the firmware file in this thread and flash straight through ODIN, or do I need to follow another guide?
