Disclaimer:

  • Once the SP flash tool has detected your device, avoid disconnecting till the task is complete as this might cause the Panasonic P91 to go dead.
  • If you accidentally selected “Autoformat – Format all”, your device will go dead and you’ll need to flash full Panasonic P91 stock ROM to revive the phone.
  • Avoid using a random Panasonic P91 scatter file (even though its for your chipset) in the 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.
