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...

I have a verizon v20 with the dirty santa unlock bootloader and i noticed that it reads the device as a US996 so I'm thinking I can try to flash the US996 KDZ and convert it into a official US996. and have a unlocked bootloader from the start. Do you guys think this is possible?
Does anyone have a US996 KDZ. I've looked for it but I couldn't find anything.
Even if you were able to flash it, US996 uses gsm networks, and since Verizon uses non-gsm network and radio utilities, it would be pointless, as you would get no service.

That's not true. The US996 supports CDMA bands. You can buy one outright and start using it on VZW by just popping in a sim. There were a few people here that did that because they didn't want any carrier branding/bloat and the ability to unlock the bootloader (before DirtySanta was available).

as Artimis said, they both are CDMA/GSM phones.
But even if that was the case, im using it on T-Mobile, not Verizon.
I just picked up a used s7 edge from a at&t customer, every thing that I could find said once unlocked it would work on any network. I unlocked it via at&t, checked that it works on an at&t sim and Tmobile but it is not working on my Verizon sim and their techs can get it to work either.
Will an At&t s7 edge work on a Verizon network? if so how? Or should I find a different phone?
Thanks

That is an interesting question. I believe all the US based Snapdragon S7 and S7 Edges have the same hardware, so you would just need to flash Verizon or unlocked firmware over the AT&T image. That part is confirmed, as people have gone from V to U and A, and A to U and V. If I were you, I'd probably go for the unbranded firmware, but that's a personal preference.
The real trick is getting Verizon to properly provision it.
At&t is gsm and Verizon is cdma not compatible with cdma you need to give carrier imei that's how cdma works not just with SIM card

The US (Snapdragon) S7 and S7 edge share the same physical hardware. There is a better than average chance that if he flashes the U or V firmware, and can get Verizon to put on their network, it will fly.
G935T to G935A

Question: to convert from one firmware to another do I have to install U first? I want to convert my G935T to G935A to be able to use wi-fi calling. My phone is unlocked and everything works on At&t except for wi-fi calling (Or VoLte as I see it referred to often)

If this is your first device with AT&T to support WiFi calling, you may have to get a new SIM (or get your current SIM provisioned correctly).
So are you saying I don't need to install the G935A firmware?
Long story short, I received a 935v (from a family member) had an frp lock dropped it off at a "cell phone repair shop" they flashed it to a gsm network provider. I am not willing to give up Verizon. Any way to flash it back to the Verizon rom? Anything that will work on their cdma network?
Just noticed how vague my question was (my bad). However I found the answer since it was flashed with bootloader 5 phone is pretty much bricked until Verizon updates to the bootloader 5.
G935V flashed to AT&T
I was thinking of flashing my 935V to a more compatible AT&T phone. My 935V is missing LTE band 12 and 17.
Would you know if flashing it with the G935U for AT&T firmware will add those bands?
I understand it removes the bloatware but was curious what bands if any are added or removed.

I have a question. If I bought this phone outright, and sprint basically locked rooting it via boot loader version 5+, could another carrier flash it with "something special" to get it on the carriers firmware? If I own this, and Sprint locked a feature on me, wouldn't that make them liable for damages?

Not really. You bought the phone to use specially on Sprint as a Sprint phone. When it came out, no one knew about the u firmware or using it on other carriers. There is a post on here about unlocking additional lte bands. If the phone is carrier unlocked, you will get some service on all carriers, but not all the bands will be unlocked.
I have an old Tmobile S7E on old ass firmware (Android 7.0 BQE1) and it's already rooted. I just went through Tmobiles Device Unlock process and I believe the phone was unlocked successfully. I'm looking to upgrade to the latest firmware that still allows rooting. I've looked through the Custom Roms threads and can't tell which one is the latest. I am also wondering if I need to use Verizon firmware or stay on Tmobile firmware.
For instance, this thread here: by jrkruse, he mentions to another user in the comments "This one or verizon one? This one just has the Tmobile csc stuff added and a build.prop for gsm carriers thats it" so it made me wonder if I'm using Verizon service but it's a Tmobile phone if this would work. I know Verizon is CDMA so him saying gsm carriers made me think it may not work.
I know this device is old and this thread doesn't get browsed as much anymore so hopefully I can get some answers. If I can't get this working I guess I'll just be getting a new 2020 model phone :highfive:
Thanks guys!
