HTC one is the best Android device till now and now a days Android 4.3 Jelly bean update is every where for all HTC One models. Those who have HTC One international model they don’t have to worry about a thing all they have to do is goto Setting>About>Software update. But those who are using carrier devices like me i am using AT&T HTC One i can not update my device through simple update. I have to goto settings > AT&T Software Update> Check for updates. Like Samsung we can not download official firmware and update it through ODIN that’s bad. Ok now lets start the process .
Things To Remember:
- Your battery should be charged 60%.
- This process is not for HTC One International Model.
How To Update At&t HTC One To Official 4.3 Jelly Bean:
Step 1: Goto Settings then At&t Software Update> Check for Updates.
Step 2: Now when you are in the menu tap on the ” Check for Updates ” and at first you will get a update of 20 MB, wait for download to complete and your device will reboot and it will take 2 mins to install.
Step 3: After the 1st update is installed go back to setting and again ” AT&T software update ” then tap on ” check for updates ” after few seconds you will get a pop-up message ” wait for 24 hours and 12 mins “. No need to worry about that , go to settings select Date & time and change date to next day e.g if its 11/3/2013 change it to 11/4/2013.
Step 4: When the date is changed go back to setting again AT&T software update > check for updates and you will get the update of official Android 4.3 Jelly Bean for AT&T HTC One.
You will get 2 updates before the 4.3 Jelly Bean update first will be 22MB second 256MB and after these 2 you will get the 4.3 update of 565.7 MB. You have to change two times date to get the main update.
