Update Galaxy Alpha to Marshmallow 6.0.1 custom ROM

0

Galaxy Alpha keeps running on Lollipop 5.0.2 and there’s no promises that it’ll receive official Marshmallow update, especially when most of us are looking forward to Nougat 7.0 release. So we thought it’s time to put Galaxy Alpha into 6-th generation OS. Tutorial given below perfectly shows how to do it.

Warning: This tutorial is only for Galaxy Alpha SM-G850F models.
Update process will erase device internal storage, so it’s strongly recommended to backup your data to device SD memory card or PC before starting this tutorial.

Prerequisites:

• The device should have at least 60% charge left on the battery.
• If you have Samsung Kies program in PC, Kies should be completely turned off to not disturb all the process.
• USB drivers must be installed on PC (if Kies are in PC then drivers are already installed).
• CWM or TWRP recovery must be installed. Don’t have it? Then follow this tutorial.
• USB Debugging must be enabled on the device. To enable it go to Settings/About phone and keep taping on Build number until you see Developer mode has been turned on. After that go to Settings/Developer Options then check USB Debugging.

Tutorial:

  1. Download ResurrectionRemix M v5.7.4 custom ROM zip file to PC or straight to mobile device.
  2. Download Google Apps package to PC or straight to mobile device.
  3. Place both files into device internal storage.
  4. Now boot Galaxy Alpha into recovery: Turn off the device, then press and hold Volume Up + Power + Home button until recovery menu show up.

  7. Swipe and wait for the wiping process to complete.
  8. Next, go back to main menu and choose Install, then locate CyanogenMod 13 custom ROM zip file. 
  9. Tap on it and swipe to begin custom ROM installation process. TWRP install
  10. After installation is done, go back to main menu, choose Install and locate the Google Apps.zip file. Swipe to install it.
  11. After process is complete, go back to main menu and tap on Wipe, then choose Advanced Wipe.
  12. Check Cache and Dalvik Cache partitions, then swipe to confirm. After wiping is done, go back to main menu ant tap on Reboot to reboot Galaxy Alpha.
