Hello! I'd like to know how I can go back to Oreo, I have pie on the August patch. I have problems with battery drain and with the front camera (over exposes photos) are not taken the same as you see in the preview.

I can't go back with Odin, I get a problem with the bit

As everyone should, although I tried and it worked. I had plenty of issues with Pie back then, the worst being huge battery drain issues, as well as bigger charging times, so I decided to rollback to Oreo using sammobiles updated oreo version and Odin in order to flash it. Had no problems ever since and everything works fine. Backup your data before you do it though, if you do it. Also, using Frija's downloader is a better idea, since it's faster.

wow! thats cool that you were able to get it done. Weird, but cool. Waas it the same bootloader version? if so, that would explain it, but just odd that an oreo and pie version would cohabitate on the same bootloader.

Also Frija and SamFirm are GODSENDS when it comes to firmware downloading. They are at least 4x faster than sammobile

I honestly don't remember the details about the bootloader :/ but it was pretty straightforward. And yes, Frija would definitely saved me a couple of hours downloading the files.. if it existed!

the Frija tool is relatively new. Samfirm has been around for quite a while. They both do the exact same thing and are awesome LoL
