BQ27510 chip Firmware Upgrade from G2 to G3

Other Parts Discussed in Thread: BQ27510, BQ27510-G3, BQSTUDIO

I have read the .gg file from the BQ27510 chip which I thought older version G2.  In that file, there is a "Device Name = BQ27510-G3". Does it means the chip itself is G3 version or the software might be already upgraded to G3 version?

I have the .bqfs file of this chip and don't know what to do with it. Any help on this please.

Thanks!

    if the gg says g3, then it means it has been upgraded. The chip is the same... g1 to g3 firmware versions will all work on the same chip.
    You can program the chip using the bqfs and bqstudio. You can write code to parse the bqfs from your host controller on the chip for mass production.
    thanks

    I have realized that the firmware is upgraded to G3 but not updated the learned values. So, I did read the gg file from g2 chip and g3 chip separately. Extracted the learned values from g2.gg and copied to g3.gg file and again loaded into g3 device. Then, taken the Golden image and now I am able to see the learned values in the g3.gg chip.
