900v on ATT... modem?

Im using a 900v on ATT, rooted, all is well with that, BUT I would like to ask if anyone can steer me straight on what modem I can flash?
Being it's a Verizon phone I'm scared lol jk
So anyone willing to help?
You need to flash the modem / firmware for your phone, the G900V. Don't try and flash firmware from other variants.

G950F model with T-Mobile US

Hello is there a way to flash the T-Mobile (G950U) firmware onto a G950F model phone or change the CSC without root? While the phone is working, I do not believe it is able to take advantage of carrier aggregation and VoLTE without the proper region code for my area. Wondering if there is any way to achieve this? Thank you.
You want to flash snapdragon firmware on an exynos phone? You sure?

Guess I went the wrong route by purchasing an unlocked phone to use on the Tmobile network. the internet is sooooo slow...

Can I flash another firmware??

Can I flash another firmware like tmobile or att on my s7 sprint ??? And how can I do that
Sorry for the noob question
Nobody knows about it???
if you have the actual "Sprint" sm-g930p, then your answer is yes as long as it's unlocked. well you can flash even if it's not unlocked, but if it isn't then you won't be able to connect to whoever your carrier is because the device will be sim/network locked to the original carrier. But honestly why flash any other carriers firmware when just simply flashing the "sm-g930u" firmware will pretty much give you all APN access and you can then connect to whoever your sim supports, with no carrier bloatware. Fully functional... Half the crap.. lol .. and a simple Odin flash should do the trick. use either prince's, or the newest build 3.12.7 i believe.. I've been using only that one and have rooted, flashed dif firmware and even tinkered with some bootloader ideas (unsuccessful) and was able to use the same odin for all.

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...
