If your Samsung Galaxy Core 2 Duos smartphone is suffering from any soft-brick symptoms like bugs, boot loops, lags, battery drain, force close, screen freeze or total blackouts, you likely should seriously consider downgrading to the stock Android operating system. You see, by downgrading and running the stock Android OS, you can run the fresh software update on your device and essentially wipe the old version. Since many of the problems you were facing were to do with the old operating system, you should no longer have that problem after the downgrade. That’s just one of the reasons a person may wish to enter download mode on Samsung Galaxy Core 2 Duos smartphones.

Although what was just said sounds like a serious reason to need to boot into download mode on Samsung Galaxy Core 2 handsets, there are some reasons that are more for fun, like getting root access or installing a custom recovery on your device. Similarly, some of you might already have root access and therefore automatic over the air updates are not a great idea. Instead of updating automatically, you will want to connect the Samsung Galaxy Core 2 Duos smartphone to the computer and update manually with a tool like Odin — or anything in the future that might arrive that’s similar to Odin. While the tools might change in the future, the official download mode attached to our devices will probably not change.

BEFORE WE BEGIN

• There are some reasons for entering download mode on the Samsung Galaxy Core 2 Duos that will wipe the data. With that in mind, you should backup the current data on your devices so you do not lose that same data. Data you might consider backing up includes the settings, pictures, video files, music files, SMS and MMS text messages, plus anything else you can think of that you don’t want to lose like the phone contacts.
• Double check that you have USB Debugging Mode turned on already before continuing. To do that, head to the Menu > Settings > Developer Options > look for the USB Debugging Mode option inside the Developer Options.
• Sometimes people don’t have any Developer Options menu available from the Settings menu because Android decided to not always make it an automatic feature. For all you guys and girls, head over to the Menu > Settings > About Device > keep tapping the build number until it says you are now a developer. It should only take about 7 or 8 taps until it’s done.

HOW TO ENTER DOWNLOAD MODE ON SAMSUNG GALAXY CORE 2 DUOS SMARTPHONES

1. Press the Power key just once and pick the ‘reboot’ option, or keep holding the Power button and eventually your device will turn off completely.
2. Reboot the device by holding the Power + Home + Volume Down keys and don’t let go of those buttons until you have read the next step.
3. Keep holding the three buttons until you can see the Samsung Galaxy Core’s screen change and a warning triangle at the bottom of the text.
4. Now release the three buttons you were holding and just press the Volume Up key by itself.
5. Soon your device will get past that warning screen and enter the download mode.
