  • Once the SP flash tool has detected your device, avoid disconnecting till the task is complete as this might cause the Tecno Spart Go KC1 to travel dead.
  • If you mistakenly selected “Autoformat – Format all”, your device will go dead and you’ll get to flash full Vivo Y91 (1816) to revive the phone.
  • Avoid employing a random Vivo Y91 (1816) (even though its for your chipset) in the sp flash tool. simply because a scatter file is for your chipset doesn’t mean it contains equivalent partition info. Formatting with a wrong scatter file could end in more problems than you initially intended to repair.
  • SP flash tool was created by MediaTek Inc. so credits to them for the tool.
