Dji phantom 4 drone battery reset

[DONETOP]

Hello guys! Pls I am new here and seek your help to solve an urgent issue for me. I have this clone type ev2400 chip connector which i used with bq studios to clear pff flag error. In deed the pf flag error was cleared and show turned from red to green . But when I plug in the aattery to the drone it tells me tells me battery error and cell broken. The battery has four cells and all the four cells voltages are read 4100mv each when  I use the ev2400. But to my surprise when I use the nlba1 software to read the battery, it's status says locked. 

I only have the bq studio to do this work because it does not require licensing.  Pls what have I not done well. If you have suggestions to what I should do pls drop the steps too..

Thanks
