Just wanted to pass along this information. A week ago i started having charging issues with the micro usb port on my phone. It was not much longer and it died completely. I had purchased my phone from best buy and paid for the Geek Squad protection plan. Being that, they replace any defective phone for no charge. I took mine in to the Geek Squad rep and the they confirmed that the charging port was borked. I had installed the ND8 OTA and had a different rom installed at the time and nothing was said about it. Anyway i got my replacement phone yesterday and was thrilled to see that it came loaded with 4.1.2. I was not happy with the whole Knox bootloader issue and am now back to running CM roms or whatever i choose. Just thought i would let everyone know that as of now they are not sending these phones out of repair with 4.4.2. If anyone else has Geek Squad protection and want to get back to a manageable bootloader situation this is still a option.
