Flashing instructions


Prerequisites

  • Your Samsung Galaxy A71
  • USB-C cable that can do data transfer
  • A computer running Windows 10 or later which has ADB installed

Unlocking bootloader

This WILL factory reset your phone. Back up any data before continuing.

  • Open Settings, and go to About phone -> Software information
  • Tap "Build number" 7 times
  • Go back, then select "Developer options"
  • Enable "OEM unlocking", and press "Enable" on the warning (if the OEM unlocking option doesn't exist, your phone is not unlockable, likely it was purchased from a carrier like Verizon that restricts unlocking so you cannot continue).
  • Turn off the phone
  • Hold down volume down and volume up, and while doing this, plug the phone into your computer.
  • Once the Warning screen appears, let go of all buttons.
  • Hold down volume up until it says "Unlock bootloader?", then press volume up again.

Installing TWRP

You will have to install Odin and the Samsung USB drivers on a computer, which requires Windows XP or later.

Installing crDroid

  • Download the latest crDroid build from download page
  • In TWRP, press "Wipe", then "Advanced Wipe"
  • Select "System", "Data", "Cache", and "Dalvik / ART Cache"
  • Swipe to wipe
  • Go back to TWRP's main menu
  • Press "Advanced", "ADB Sideload"
  • Swipe to sideload
  • On your computer, run "adb sideload [path to crdroid.zip]".
  • If wanted, you can also install GApps.

On first boot, the phone may remain on the Samsung Galaxy A71 logo for several minutes, this is normal and only happens on first boot, however in some rare cases, the phone will hang. If the phone doesn't go past the Galaxy A71 logo after 15 minutes, hold down power+volume down to reboot the phone, afterwards it will boot.
