I am getting ready to help a friend update the firmware on his 2012. I was just provided a copy of 2.90 sys.bin and started doing a little reading on doing the update. I came across some threads were people were having some issues with errors after doing the update and it was being recommended to go with the 2.80 instead. I was able to track down that file as well. So I have both. Has anyone recently had any issues with the 2.90? If you had a choice, is the 2.90 the way to go or is 2.80 a better choice?
