Hi everyone. Im new here, i created an account to see if you guys could help me solving a problem. The thing is that today i finished downloading the new android marshmallow update, but when it was 83% the download failed and now its stuck in recovery mode (the one with black screen right?). I have an unlocked stock htc one m8 non rooted. I bought it in the US like 5 months ago and brought it here to Argentina where i live. Every time i turn on the device and after all the android screens show up, a red question mark appears for less than a second and then it goes in recovery mode. I don't know what is going on so i'll need your help. Let me know if theres something you guys can do. Sorry for my bad english and thank you in advice! Cheers.
