I have the Red screen issue with an error 4013 in my iPhone 5s. Tried all easy ways to start the phone. Even swapped the display unit with another 5s, which didn’t work. Only remaining option I came across was changing the Nand. (I can’t do that). So, is it possible to replace the complete baseband from another iPhone 5s to the 5s with 4013? I don’t mind loosing data. Also, what problems would I face while doing so? And what is the most appropriate way of doing so? [br] Thank you!
