Using the Android operating system for the first time can be daunting. For starters, you don’t really get a manual letting you know what to do, so you’ll need to just dive right in and see how it goes.
Anyone with experience in computing over the decades might be a bit hesitant of pressing too many buttons because they’ll be all too aware how quickly things can go wrong.
But a modern day mobile operating system such as Android doesn’t really have any quirks in it that will cause it to stop working easily. If you were more of an advanced user and you did manage to create an issue, or the software itself is to blame, then you would be able to rectify whatever the problem is by jumping into the recovery partition and then applying a newer version of Android or taking a factory reset.
The option of taking factory resets and applying updates means that there isn’t really any need to become an Android expert for knowing how to solve problems, but there are some things that Android with its stock recovery partition doesn’t allow for, and that’s why you might want to think about changing it for a different one.
If you want a change from the stock recovery, the only choice you have is to install a custom recovery instead. You might find a few custom recoveries available, but if the device is new and the custom software being created for it as modern, then you’ll want to install TWRP whenever it is available. It’s the only custom recovery being maintained and continually developed today, as the competition that used to be there as allowed TWRP to take the reins and be the clear de facto custom recovery of choice for everyone.
How to Install TWRP Recovery on Samsung Galaxy Core 2 (SM-G355HN) Using Odin
Note: The Odin flashing tool is really easy to use, but it only works on the Windows operating system. You won’t get the flashing tool to load on a Mac or Linux computer. It doesn’t really matter what version of the Windows operating system that you’re using as long as it is something above Windows XP.
1. Download and install the Samsung USB drivers on the computer if you don’t have them already.
2. Download the TWRP Recovery for the Samsung Galaxy Core 2 (SM-G355HN) smartphone from one of the mirror links below that’s for your region:
3. Download the Odin flashing tool.
It doesn’t matter what version, but the latest is the most up to date so grab that one. Extract the Odin file and then double-click on the Odin executable file (.exe) that is found from within the Odin folder after extraction. You should now have the Odin interface open on the computer and waiting for you to connect to it.
4. Boot the Samsung mobile device into the Download Mode by first powering it down and then rebooting by holding the Volume Down + Home + Power keys at the same time.
5. A yellow warning triangle will come up on the device’s display. At this time you need to press the Volume Up button. You’ll then see the device getting into the Download Mode. It’s then ready for the flashing.
6. When in Download Mode, connect the Samsung mobile device to the computer with the USB cable.
7. If you have installed the USB drivers correctly, the Odin flashing tool should detect your device. You can tell this by observing the ID: COM port lighting up with a color, usually yellow or blue.
It doesn’t matter what color, it’s the lighting up that counts.
8. After the device is picked up by Odin, click on the PDA or AP button, depending on what button your version of the Odin flashing tool has.
9. Navigate to the stock ROM folder and upload the tar.md5 file to this location in Odin.
10. Without changing any of the default settings, click on the Start button in Odin, and the flashing then begins.
11. Wait until Odin shows a Pass message before disconnecting your device.
