Hey guys, need some assistance here but I am familiar with flashing, rooting, etc. I currently have an N975U1 and would like to install the AT&T N975U firmware so that I can get all the AT&T features. My Note 10+ is currently running the July 1, 2020 firmware. I tried to flash earlier released firmware via odin but they all failed. I suspect it's because I was trying to flash firmware with an older bootloader than what is currently running on my device. Therefore, I will ask the questions below.
Which AT&T firmware will successfully flash to my device and what is the link to that file?
Which version of Odin do I need to use? I previously used a 13.3.1 patched version so a link to what I should use would be great!
Thank you so much!
