Root & Install TWRP Recovery On Samsung Galaxy Core 2 SM-G355H/G355HN

Galaxy Core 2 is Samsung’s 2014 low-end device, which is a successor of the original Galaxy Core. Samsung equipped this device with a 4.5-inch 480p display. A 5 MP shooter is planted at the back and the secondary cam is VGA. Samsung used a 768 MB RAM accompanying a Quad Core 1.2 GHz CPU. Internal storage is 4 GB with an external card slot having the support up to 64 GB. Galaxy Core 2 runs on Android 4.4.2 KitKat, Samsung hasn’t announced any plans to update this device to any higher version of Android. In case you’re a Galaxy Core 2 owner and you’re not looking forward to enhance and tweak the performance of your device by means of custom ROMs or by applying system tweaks using different root specific applications, you might be in a need to be capable of doing all this custom stuff on your Galaxy Core 2.smartphone-samsung-galaxy-core-2-duos-dual-chip-3gandroid-4.4-cam.-5mp-tela-4.5-34-proc.-quad-core-086774700

To begin with the custom stuff, the very first thing you need is to gain the root access on your phone. After having it rooted, you will be able to install applications like Titanium Backup, Greenify, System Tuner etc. Having the device rooted will allow you to access the core of your Android system and you will be able to make changes to improve performance and battery life of your device. The second important thing to play with custom stuff is to have a custom recovery installed on your device. There are two popular custom recoveries, CWM and TWRP. Custom recovery allows you to create and restore Nandroid backup, mount your system from recovery mode, wipe cache and dalvik cache, flash zip files of custom ROMs and Mods etc. Now that TWRP recovery is available for our beloved Galaxy Core 2, we will be installing it on this device in the succeeding guide.

We are about to show you how you can install TWRP 2.8 recovery on your Galaxy Core 2 SM-G355H and SM-G355HN. After installing TWRP, we will flash file to root this device. Let’s go ahead and get this done now.

    i didnt understand step 10.

    • @disqus_vORo6Y6wrU:disqus in step 10, you have to flash SuperSU to root your phone. You will tap the Install button in the main menu of TWRP and then locate the file which you copied to your internal or external storage.

      I hope this has been cleared now. Let me know if you need any further help.

  • Vagelis Delapo

    eventhough i complete the 10th step my sm-355hn is still no rooted plz help.there is not the command install though in the recovery but an other command that say’s apply update from external source and then i am finding the SuperSu i am flashing it . it say’s installation from external source completed but the root checker after made me feel sad ‘ this devise is not rooted ‘ . plz help

    • @vagelisdelapo:disqus it looks like TWRP wasn’t flashed on your phone. You will have to flash the TWRP properly. If flashing using the instructions above isn’t making the TWRP stick, then flash a stock fimrware on your phone and follow this process all over again to flash the TWRP and then flash SuperSU afterwards.
