I've searched a lot on XDA and other forums to get a solution, but I can't find anything that's can help me. I can't seen it to Google because I can't find his original box and the original receipt.
My phone can take signal only using "xTraSmooth" rom, but is very old and I want to use Pure Nexus.
I've added this string to my build.prop it was posted as a potential solution:
And I've changed *#*#4637#*#* option to LTE/GSM/wcdma auto (prl)
But at every reboot it set itself on LTE/GSM, with or without the build.prop string.
I know that is a common problem, but no one found a real solution.
Thanks in advance.
