Help I need to replace preinstalled Sprint with Stock ROM

[Deleted User]

I bought an open box (suposedly) unlocked phone. I was able to activate it with ATT, even though the phone is preinstalled with Sprint version of the software. The software is problematic and I want to replace it with the stock version, but I am a novice at this, and none of the recommended methods have worked for me. I feel they are not mentioning things they figure I would already know or something. Can it just not be done? I can't uninstall or even disable any of these Sprint apps even though I am not using them. I downloaded the Stock ROM from Motorola for this device, but the phone won't take it. Do I have to get the Sprint out first? If so, how do I do that.

Sorry for rambling. I guess I just don't know what questions to ask.

this is why i never like to play around with unlocked phones and hop from one provider to another. it can get very complicated. i do not think if you flashed an att firmware it will work on your device. firmwares are very device specific. the only thing i can think of is to root the phone and flash a custom rom.....or....you can just learn to deal with having sprint bloatware and move on.

edit: i think this is what @Dannydet was trying to say in such few words......LOL

I didn't do that. I tried to flash the stock rom from the motorola site itself, which was specified for the G7 Play. They have three to choose from. One for Canada, one for the US, and one specific to Sprint.

Different carriers rely upon different cellular networks so there are compatibility issues to take into account, especially here in the U.S. where we have very territorial, highly competitive carriers that are more focused on profit and their respective market shares than their customers.

You referred to buying an 'unlocked' model but keep in mind there's a difference between the boot loader unlocked and carrier unlocked.

This phone is apparently a branded (Sprint) phone so its internal hardware configuration, specifically the cellular radio chip, is going to be fully compatible with Sprint's cellular network but it may or may not be the same with AT&T's cellular network. Keep in mind that ROMs are very device specific so if you flashed this phone with a ROM for a different model you need to re-flash with the correct ROM. Each ROM is created to match each model's hardware configuration, and each model has its own unique hardware components inside -- i.e. different processors, audio chips, radio chips, etc. Each ROM contains only the drivers, firmware, software to match with the hardware so using a different ROM is going to result in a mismatch of software and hardware. Simply flashing a different ROM, nor using a different SIM, will change a branded phone from one carrier to a different one -- in this instance the hardware
Sprint has moved more towards 4G/LTE so that's good for compatibility, but at the same time T-Mobile has recently bought it out so Sprint-specific phones are going to become obsolete in the near future.
