I am writing because I have a serious problem with the display of colors by phone lg optimus 4x hd.
The problem is that the screen does not have a fully color. Lights very dark purple color.
The screen certainly is efficient because when you turn your phone on for the first 5 seconds LG logo is displayed complete correctly and then displaying the color goes in the form described above.
The problem began with a download applications TWRP Manager (root) and pressing random model P990 instead of P880.
I tried to fool the problem by installing a new CM 11 and set the color corrections on the phone and it worked but when the phone restarts it lg animation and recovery is still dark and purple and when I returned to that of the original system again, everything was dark and purple.
When installing a new CM 11 chose all possible formats and wipes that were available in CWM 18.104.22.168. If necessary I can post pictures and record video.
Please help coped with a lot of things but this exceeds my knowledge of advanced management android.
I apologize for possible errors in the spelling of English.
