How to Unlock Bootloader of Chinese Samsung Galaxy using CROM


Samsung has a really cool list of devices released under the Chinese region. To cope up with the powerful challenge between smartphone giants in China, Samsung also manufactures smartphones in a good budget having high end specifications. If you just have a look at devices like Galaxy C5, Galaxy C9, Galaxy A9 and others, you will find out that these devices carry the specifications almost similar to the specifications of Samsung’s flagship devices all around the world. Now these devices in China come with certain limitations.

The limits include no sign of anything Google on the phone. Galaxy smartphones in China do not have any applications like the Google Play Store, Google Play Music, Youtube etc. Another restriction on these devices is the locked bootloader. That sounds weird right? A Samsung Galaxy with a locked bootloader? Well, that’s actually right. The phones in China are as same as the phones released by different carriers. The bootloader is kept locked to keep the users away from modifying or tweaking their smartphone.

The bootloader is definitely locked, but unlocking it is not as hard as unlocking the bootloader of a carrier branded Galaxy smartphone. To make it more than easy for the Galaxy smartphone owners in China, Samsung has its own CROM Service application. CROM Service takes only a few taps to kill the bootloader lock on the device. Once you have unlocked the bootloader, you are free to flash a custom recovery on the phone or root it. Doing this on your device will ultimately lead you towards the installation of applications and features which are not apparently meant for the Chinese region.
