Hi guys, I read about this problem in the internet but can not solve it myself. First two weeks I used the Android I had no problems at all and even bought two new batteries so that I can keep on using my M8. But now the phone is not reliable any more. Today I couldnt get it out of airplane mode at all. I evene deleted the android files and have redone and updated the phone but still in airplane mode. I dont know in which file the airplane mode is stored but this way I can not use the M8 anymore. WOrst thing is, when I went back to the original firmware without the dualboot, I didnt get a signal either....with my old phone it works so can not be the operator. Any thoughts?
