The Samsung’s Galaxy Mega 6.3 I9200/I9205
The Galaxy Mega 6.3 ran on Android 4.2.2 Jelly bean. Samsung didn’t really release updates for this device. The last update they released was to Android 4.4.2 KitKat. If you have a Galaxy Mega 6.3 and you want to get a taste of Android Marshmallow, you are going to have to flash a custom ROM.
One of the best and most widely used custom roms is CyanogenMod 13, and it will work on the Galaxy Mega 6.3 I9200 and I9205. In this post we will show you how you can flash Android 6.0.1 Marshmallow on a Samsung Galaxy Mega 6.3 I9200 and I9205 using Cyanogen Mod 13.
NOTE: This particular MOD is still in its development stage. It is expected that it will have a handful of bugs and might not really be good for everyday use yet. Mostly this ROM is used to give the look and feel of Android 6.0.1. If you are a newbie to flashing ROM’s you might want to wait for newer builds to come up.
Prepare your device
- This ROM is only for the Galaxy Mega 6.3 I9200 and I9205. Don’t use it with other devices as you could brick the device. Check your model number by going to Settings> About Device.
- Charge the battery of your device to at least over 50 percent to avoid running out of power before ROM is flashed.
- Have TWRP Custom Recovery installed. Use it to create a Nandroid backup.
- Back up the EFS partition of your device.
- Back up important contacts, SMS messages and call logs.
Note: The methods needed to flash custom recoveries, roms and to root your phone can result in bricking your device. Rooting your device will also void the warranty and it will no longer be eligible for free device services from manufacturers or warranty providers. Be responsible and keep these in mind before you decide to proceed on your own responsibility. In case a mishap occurs, we or the device manufacturers should never be held responsible.
- Connect phone to the PC.
- Copy the downloaded zip files to phone storage.
- Disconnect phone and turn it off.
- Boot it into TWRP recovery by pressing and holding the volume up, home and power buttons.
- When in TWRP, wipe the cache and dalvik cache and perform a factory data reset.
- Choose the install option
- Select Install and choose the downloaded ROM file. Click Yes to flash the ROM.
- When the ROM is flashed, return to the main menue.
- Select Install and choose the downloaded Gapps file. Click Yes to flash Gapps.
- Reboot the device.
You may also choose to root the device after installing this ROM. You can do so by going to Settings> About Device and looking for your build number. Tap the build number 7 times to enable developer options. Go back to settings and go to developer options. Choose to enable root.
The first boot of your device after installing this ROM could be as long as 10 minutes. If it’s taking longer than that, trying booting into TWRP recovery and wiping the cache and dalvik cache before rebooting your device again. If your device is really having issues, return to your previous system by using the Nandroid backup you created.
