I've applied a previous OTA successfully (after I went back to a stock recovery, of course).
But this time, it fails partway through and shows the red triangle with exclamation point. I was able to boot the phone to Recovery and do a Vol+ & Power which enabled me to select a handful of different options, chose to do the option of installing an OTA .zip file. Anyways I browsed to the OTA file in internal phone storage, executed it and it stops and fails on the following message: "cimext9.odex has unexpected contents". I am stumped because Google couldn't help. But, something similar happened to another person and they had installed Adaway which must have changed system files. I did have AdblockPlus installed for a while but uninstalled it - so could ABP be the culprit, and now what are my options that would enable this OTA to get installed on my phone?
Thanks in advance. Still learning, appreciate the help this board has provided me so far.
