Install ParanoidAndroid Custom ROM on HTC One S and Update to 4.1 Jelly Bean

HTC-One-S

After we have seen how to install different Android 4.1 based custom ROMs (like AOKP, or CM10) on your HTC One S, now I will explain you how to easily update your handset with the latest Paranoid Android firmware. By flashing this new custom ROM you will be able to upgrade your smartphone to the Jelly Bean platform and also receive tablet dedicated capabilities as the Paranoid Android software is a phablet UI that perfectly combines features from the tablets and smartphones areas. You have the proper tutorial below, so let’s get started.

As we are dealing with a custom ROM (the present update isn’t coming from HTC so it’s not the official Jelly Bean OS suitable for your One S) for being able to install the Paranoid Android platform you will have to follow and complete a manual procedure; the same is being detailed during the next few lines, all being explained in some easy to understand steps. The operation is being considered risky, so be careful in what you do and don’t apply things without consulting the below lines. Furthermore, if you get stuck or if you are having problems in understanding something, don’t hesitate and contact us.

As mentioned, the Paranoid Android ROM is being based on the Android 4.1 Jelly Bean OS, so your HTC One S will be updated to the same. All the new features introduced by Google to its latest platform will be now ported to your phone along with extra ones that cannot be found in the default version of the Android system. As usual, a custom ROM is bringing its own interface, in this case a tablet one, and looks, so you can personalize your handset by your own taste. Furthermore, by installing the update you can easily upgrade the performances of your device by increasing the battery life, customize and optimize the internal system, improving the speeds and adding the latest features available.

But first, before applying the proper steps and install the Paranoid Android software, I recommend you to backup the HTC One S data. You should save the personal info each time you are about to change something on your phone, as there are big chances to lose the same. Of course, the best way for avoiding that will be by completing a backup and this is exactly what you should do at this point of the present guide. If you don’t know how to take care of this operation, I have mentioned some tips below. Read the list and see if you find the info helpful enough.

  • Download SMS backup and restore apps for Android and save the text messages from your One S.
  • Download call log backup and restore tools from Google Play Store.
  • Sync with Google and backup the contacts.
  • If you have a custom recovery image installed (you will have to install one anyway) then you can use it for backing up the current ROM. If somehow something bad happens, you can easily restore your old OS.
  • Use a computer or SD card and save the rest of the files from your smartphone.

Now, as the data is in safe hands, you should unlock the HTC One S bootloader. It cannot be updated to Paranoid Android OS otherwise so follow the link from above for a suitable tutorial. Furthermore, after unlocking the system you must install a custom recovery image (preferable CWM recovery) on your handset. And finally, you should install the HTC Sync software from here. Be aware as by the time you unlock the bootloader, the warranty will be void. Unfortunately, the only way for regaining it back will be by updating to an official update released by HTC and suitable for your One S device.

As soon as you take care of the above mentioned procedures, you must ensure that you can use a Windows running computer, your phone and its USB cord. The USB debugging option must be enabled on your One S and the security programs (Firewall and antivirus protection included) which are running on your handset and computer must be deactivated. Also, your phone must have enough battery life (at least 70%) for staying “alive” during the update process. Don’t apply this tutorial and don’t flash the Paranoid Android custom ROM on similar smartphones with the HTC One S (the one that runs the 1.5GHz dual-core processor) as you can brick your devices.
