I was just curious if it was at all possible to flash the firmware from the T377P model to the AT&T model (T377A) because it seems like most of the development is for the T377P. Has anyone achieved this yet or attempted flashing any other model's firmware to the T377A?

Flashing SM-T377P firmware on a SM-T377A wouldnt work, because the T377P uses a Snapdragon 410, not an Exynos 3475 like the T377A uses. Flashing SM-T377T (T-Mobile) firmware might work, since it uses the same Exynos CPU as the T377A

I'm just curious what the best alternative firmware would be to flash (if possible at all) on this tablet because there's absolutely zero development on the AT&T variant (T377A) of the Tab E. Preferably a firmware that's been successfully rooted, etc.

Unfortunately nothing can be developed for the T377A because the bootloader on that variant is locked, so that means we can't do anything to the device, even with Odin. If there was a way to convert a T377A to a T377T, or if there is engineering firmware for the T377A, then maybe development is possible.

On another note, I found somebody's backup of the Nougat firmware for the T377A: https://mega.nz/#!eHJSUCoZ!54BXNlvrL6RJfEHzS4qNOj3eqwCpxSrzrI2l_IqHe84
Contains the AP, BL, CP and CSC files.

Need help with FRP for Galaxy Tab E SM-T377A

I have no clue what my email or password is for my tablet, I got messed up and started changing things and now I just want to find out how I can just boot from SD a fresh ROM or something.

You have to request the unlock code from AT&T, there's a slight difference between doing it for phones from your own plan or someone else's phone (you received as a gift or purchased second hand). They walk you through the process for each type of equipment so it's relatively smooth.. I just want to remove the bloatware and have a security update more recent than tree years old. This is my main gripe with AT&T, stuck with questionable bloatware and a vulnerable version of Android (and it's locked down so tight no one can fix it on their own).

More details would be nice. A lot of us have been desperate to do something with this tablet.

    So you were able to unlock the bootloader by following an AT&T tech over the phone?
