I own an unlocked Samsung G920A which I actually flashed to a G920AZ (Cricket Wireless (who is owned by AT&T)). I now want to flash to T-Mobile as I want to be able to 1. get Marshmallow. Cricket may never. 2. Be able to use WiFi calling and you can only do that with the TMO image (from what I read). I downloaded the G920TUVU3EPD1_G920TTMB3EPD1_G920TUVU3EPD1_HOME.tar and using Odin tried, but it fails.
Is it possible to flash to the T-Mobile firmware/ROM ?
If it is impossible, then I think I would want to go to the G920A again to get Marshmallow 6.0.1, then simply pop the T-Mobile SIM in, update APN, etc. Unfortunate though as the LTE bands all work. Seems sh***y it wouldn't work to use their firmware.
I just purchased a Galaxy S7 SM-G930T online but I live in Canada and use the Koodo Network. I can put my Koodo sim in and it all works fine but I want to update it from 6.0.1 to Android 8, and it wont let me do it OTA if I dont have a T-Mobile sim. Can I download the stock T-Mobile Android 8 Firmware and flash it using Odin and still be able to use my Koodo sim or does flashing the stock firmware lock the phone?
Thanks
My Uncle got me a verizon galaxy s7 from USA and now I am trying to run a 4G sim in it but it isn't working as VoLTE is not activating ( something called Advanced HD Calling) as verizon wants verification for it and as the device is here we can't do that
I was thinking of flashing an Indian Firmware on it
Will that help me ??
Or is there anything else I can do.
Please Help.
update 1 : I managed to unlock the bootloader
If it's a Verizon S7 it'll be a G930V which uses Snapdragon, you can't flash Indian firmware on it because India uses the G930F model which has Exynos SoC.
Also despite the bootloader unlock option being available and toggleable in developer options, it doesn't actually do anything on USA models. Don't attempt to flash custom recovery, it'll brick.
Your best bet would be to flash the unbranded USA firmware (G930U) which should rid the phone of Verizon, however it's unlikely that'd let you use local carrier VoLTE.
I can run an Indian Sim in this device its just that the Volte doesn't work
I can still make it work with an app from the provider
should i just make do with the app or try the unbranded firmware?
also the other s7 my uncle sent me has FRP locked and the seller can't obviously give me his gmail to unlock it.
Is there anything I can do to bypass it or do I have to send it back to USA? also i have no clue if it has OEM unlocking enabled
I have a sim unlocked ATT Galaxy S8+ on Android 9 (Pie) being used on the VZW network.
I would like to flash to the"unlocked USA" firmware but retain Volte (CSC). I have read the unlocked firmware does not support VoLTE.
Is there anyway to do this?
Thanks in advance.
***Update***
Process Complete.
Have an unlocked tmobile s8 active I'm using on the AT&T network that I'd like to be able to use wifi calling on cause i get lousy cell reception at my place, is it possible to flash the AT&T fireware onto the device? ive already tried using odin and the stock AT&T 8.0 android oreo firmware i found in a different thread but it fails.
