Hey guys I need help updating my HTC One M8. I am trying to update my M8 to 4.4.3 and the update failed. I got the Red Triangle Exclamation Mark. I flashed the right stock recovery and the update still failed. I know the update is failing because my M8 is rooted with supersu and I even tried to full unroot in supersu settings and that did not work. Supersu is still on my phone. I need a stock backup non rooted stock rom. I can't find a stock backup non rooted stock rom for my M8. My M8 is on 4.4.2, The software version is 1.54.651.10 and the cid is spcs_001. So then I tried RUU to update my phone and the RUU did not work. I got the error 155. "The ROM Update Utility cannot update your phone. Please get the correct ROM Update Utility and try again." I can't open the View ReadMe , I click on the button and the readme won't open. Now it says to start the recovery process. What do I do now? I don't understand how the RUU didn't work? I know I downloaded the right RUU. I downloaded from here.
