I have a basic problem to unlock bq9000. I don't count with a cp2112 board, I have fx2lp board. So DJI battery killer doesnt work for me, is there a way to read and write eeprom with karosium code? or a way to access dji battery killer code so i can implement over karosium?
I managed to get to boot access mode on bq9000 with your bash script but Im stuck now.

This worked for a battery from an ASUS X540 with AS19MED3 firmware on a bq9000 chip.

Please tell me how you found the blocking flag, by what method. I have a battery on an 8055 chip, I found the charge cycles and the full charging current, but I can’t find the TDA blocking flag. Please tell me.

Hi Anandakrishna,
firstly, thank you for sharing your experience, you did a really great job! But I would like to ask you - is it possible to achieve unlocking BQ9000 chip only with Linux? So without using DJI Battery killer software. If I understood correctly, you used it in this video only for reading/writing EEPROM, right? Isn't it possible also in linux, with some script?

I have a firmware file being read, but it is empty in the HEX editor. Can you throw off the bin file of the sewing, ?

My battery is not recognized on the laptop, does that mean the BMS is burned out?
