Here is a photo with the battery holder removed. Are the pins shown for flashing firmware??

I believe they are, but Brymen don't want any (including me) to have the programmer or the details.

I think I posted a photo of it compared to some other meters some time back, will try and find it again.

I was guessing that connector allowed them to perform the alignment semi-automatically. There appears to be two other unpopulated connectors which I was guessing were for development and not needed once they got into production. During my evaluation, any changes the to firmware required that I change ICs.
Hopefully the majority of the problems have now been corrected and there will be little need for additional firmware changes.
Just a quick check, the unpopulated 4-pin connector with the two pairs of common pins is on the back side of U20 and ground, used to power the meter during development or provide power to some peripheral.
The other unpopulated connector is not in parallel with the one you asked about. It's possible that these two unpopulated connectors were both intended to control an add-on peripheral rather than development. The LCD is far enough away that there is certainly room to add something but with the lack of mounting holes in this area, my guess is they are both for development. Probing the two connectors, I didn't see anything while trying different modes.
