Stock Firmware for XT 1032 4.4.4
Hi there, does anyone have an update on this, I have soft bricked my phone and tried everything and trying to flash this rom seems like the only next logical step except it does not seem to exist, which is a bit of a downer seeing as I thought I had the Moto G 4g lte, these matters suggest that I really have XT 1032 and now the stock firmware for me does not seem to be about. Can anyone help please?? thanks a lot ric

Thanks a ton! Should I root it first and then flash to 7.0 or would I need to have 7.0 and then root it? Or should I just avoid 7.0 all together?
Firmware first then root, if you do root first it'll just go away with the Odin flash.
7.0 or not is personal preference
I successfully flashed to 7.0.
That thread doesn't have a link to download the SM-G930 ENG BOOT.
I found this page, https://forum.xda-developers.com/ve...-to-notes-root-install-xposed-unroot-t3411039
Found the correct boot eng for my phone https://forum.xda-developers.com/ve...er-samsung-galaxy-s7-sm-t3665821#post73893603
Successfully rooted!
Thanks guys, you werea big help!

My firmware update

I have a firmware update to B389 and after downloaded it get error message
My phone is Chinese version FRD_AL00 rebranding successful to FRD_L19
What's this problem ?!!
I need answer please
It might help if you share the error message. But as a starter for 10, is it an issue that you used the firmware for a 64GB phone to rebrand your 32GB phone?

I think you can't update your phone if it's born with another model number
