I have galaxy s6 gold 64gb i just received today, which replaced another galaxy s6 black sapphire I had returned bc it came defective... so before sending back the black I did a full back up of it. so when the new phone arrived today I rooted and restored it with backup I had from the other phone and now it has no signal at all . when I go to settings and status it shows unknown for baseband, IMEI, ect. please help.. I flashed the stock with odin a few times and still nothing...the last flash i also checked nand erase all and the when i turn the phone on it goes directly to stock recovery and doesn't boot into android....
