Disclaimer:

  • Once SP flash tool has detected your device, avoid disconnecting till the task is complete as this might cause the HUAWEI Y3 2017 CRO L02 to go dead.
  • If you accidentally selected “Autoformat – Format all”, your device will go dead and you’ll need to flash full HUAWEI Y3 2017 CRO L02 stock ROM to revive the phone.
  • Avoid using a random HUAWEI Y3 2017 CRO L02 scatter file (even though its for your chipset) in Sp flash tool. Just because a scatter file is for your chipset doesn’t mean it contains the same partition info. Formatting with a wrong scatter file could result in more problems than you initially intended to fix.
  • SP flash tool was created by MediaTek Inc. so credits to them for the tool.
