Another thing came into my mind in our country reselling of used battery is trending due to higher cost of new battery. I think he bought it from online store with modified eep after arising this unsupported issue he bring it to my workshop. Some technicians are modifying serial with their own code to identify that battery is repaired from their workshop later (one of them told me this story), they even don't know the complexity of such vulnerability. Thanks to Ukrainian expert who told me about Lenovo id while talking on his telegram channel.

There are some costly software available which provides only license to rewrite the IDs (i just Heard about it)

@djibattworkshop i could not even change its Serial because it needs sanyo tool. You better now what could I do with bq8050 while using NLBA1. 

I aready get .senc backup files from him for hp, dell batteries with bq20zxx, bq30zxx, bq40zxx .etc which works 100% ok. Those files could be rewrite by bqstudio/beqevsw after putting boot mode.

You can't flash .senc file with BQEvsw on BQ805X because the chip doesn't have TI firmware.

@torture yes it could be done by sanyo tool as we talked few months ago.

@torture

Very cheep discount 5000 USDT :d  

We can try flashing the .senc image that you have but i take no responsibility if something goes wrong.

 bqEVSW could write SENC on bq8055 chip which has v5.02 TI bootloader same like bq30z55 but not on bq8055a. This chip has custom bootloader v5.04 and attempt to write a SENC throws this error. 

 The only Sanyo Tools with bq8055a support could do it. 

@torture Interestingly, we were all right; the customer came back with another battery and told me mistakenly that I gave you a battery of another model placed at my home. The real battery has a different chip, which means the BIOS of his laptop does not support the BQ8055A chip; it supports BQ20695.

Some laptop schematics mention the battery chips that were supported in that particular laptop.
