phantom 4 pro PF reset procedure

[owenfred]

Hello all,

Just posting my notes on the PF reset. Please make sure your batteries are still functional before taking the steps below.

Connect your battery to rpi and connect the i2c per the youtube video https://www.youtube.com/watch?v=P5PNOO2GebY

Here are the commands to reset the PF flag:

sudo i2cdetect -y 1

• find the address of the battery mine was 0x0b
  ./comm_sbs_bqctrl.py -a 0x0b read BatteryStatus
  ./comm_sbs_bqctrl.py -a 0x0b --short monitor BQStatusBitsMA
• check for PF flag
• if set continue to Unseal battery
  ./comm_sbs_bqctrl.py -a 0x0b sealing Unseal
• Reset PF flag
  ./comm_sbs_bqctrl.py -a 0x0b trigger ManufacturerAccess.PermanentFailDataReset
• Check PF Flag reset
  ./comm_sbs_bqctrl.py -a 0x0b --short monitor BQStatusBitsMA
• Reseal the battery
  ./comm_sbs_bqctrl.py -a 0x0b sealing Seal

Hope this helps others.
