blazed

The recently released Samsung Galaxy S Blaze 4G, which is a mid-range with decent specs smartphone, can now be updated to the latest Android OS version, the Jelly Bean one, as those of xda-developers had just made available the Android 4.1 based CM10 custom ROM firmware for your handset. Therefore, during the present tutorial we will be checking in how to install the CM10 ROM on the Galaxy S Blaze 4G. Before applying the proper steps you should complete the pre requisites and read all the lines from below because this is being considered a risky and complex operation and you don’t want to damage your phone while trying to update it.

As you know, the S Blaze 4G was launched this year on March, but that doesn’t make this device a high end one. Of course it comes as the best opportunity for those who want to enjoy the Android experience on an affordable price and also enjoy some decent performances. But, what is so bad with this handset is its operating system; unfortunately Samsung decided to release the Blaze with Gingerbread and not even with ICS instead. That’s why it’s your job to improve the system with the latest platform available. In this way you will be able to improve the performances and upgrade the features. And, of course, CM10 will provide all that for you.

Therefore, as you can see, learning how to install the CM10 custom ROM on your Samsung Galaxy Blaze 4G for updating the same to Jelly Bean OS is no longer an option for you; at least not if you want to use your smartphone on its full power. Anyway, you should know that this is not the official CM10 firmware, the software being developed and tested on the S Blaze 4G by those of xda-developers, so we have them to thanks for the present step by step guide. Furthermore, by dealing with an unofficial update, you must understand that you won’t receive the classic or default Android Jelly Bean platform. There will be added extra features and the OS will come with its own interface, theme and so on. But for more aspects about the features, the reported bugs and about the things that are working on this version of CM10, you should check our source page from here.

Now, if you want to apply this guide for your Galaxy S Blaze 4G, then you must first gain root access for your phone. CM10 will run only on a rooted system, so you can’t proceed without taking care of this operation. By rooting the warranty will be void and the only way for restoring it will be by downgrading to the stock ROM or by updating with an official update released by Samsung (we don’t know when the OTA release will be available). You have a how to root the Galaxy S Blaze 4G tutorial here, on Android.gs, so don’t hesitate and use the same. Furthermore, after performing this, you must also flash a custom recovery image on your device. CWM recovery might be the perfect tool for you. A suitable guide can also be checked through our how to section (just click on the link from above and use the method from there).

Then, of course you shouldn’t forget your data. That means you have to backup all the data which is being stored on your Galaxy Blaze. For flashing the CM10 update on your phone a full wipe of the system will be required therefore you can lose your personal info. I have displayed some backup tips during the list from below along with other pre requisites, which must be completed before heading to the proper steps.

  • If you want to start the backup by saving the current ROM, then you need to learn how to use CWM recovery for this.
  • Then, probably you will want to save the contacts list; for that you must sync with your Gmail account.
  • The text messages can be easily saved by downloading SMS backup and restore apps.
  • Also, by downloading suitable backup and restore apps you can save the call logs.
  • Don’t forget the EFS folder and the internet settings.
  • For other files use a computer or the SD card.
  • Next, on the computer you will use and on your smartphone uninstall the security programs.
  • Enable the USB debugging option from your phone: “Settings -> Applications -> Development -> USB debugging”.
  • Charge the handset’s battery so that you can be sure that it won’t get tuned off in the middle of the process.
  • Do not apply the steps from this tutorial if you own a similar device with the Samsung Galaxy S Blaze 4G as you can end up in bricking it.
