Hi @loliconic

Update on my request—I left the two batteries (SN 04A9, 0041) for a few days, and somehow they are now 'Unlocked' and working fine. I can use them straight away.

While working on the L20D4P71 battery (Renesas 047A20 chip), I applied the same cell injection method to the L20M3P71 battery (Renesas 045A20 chip). Out of 4 units, 2 were successful (Unlocked, Balanced). However, the other 2 units remain 'Locked' despite being 'Balanced'.

I have attempted to Reset these 2 units, but it was unsuccessful. Could you please assist me with a remote reset?"
