Reconifiguration Actia master/slave BMS Pwd needed

Hi,
I have a converted Audi A2 with a 100V Lifepo4 battery in 30s2p configuration (50Ah cells). It is equipped with an Actia Master and 6 Slaves. Since the Cells are very old and degraded I would like to change them out against 100Ah cells. Therefor I would have to reconfigure the BMS from 60cells to 30 and ofcourse the rest of it. Unfortunately I would need a Password for the web server of the BMS and Actia doesn‘t support the BMS anymore (you could buy access a few years ago). Is there any way to access the web server or is it impossible to save the otherwise complete useable BMS?
Any advice is appreciated!
Karl

Sorry, but does anyone happen to know if there’s a way to reset the BMS password through a hardware method, or if there are specific diagnostic tools that might allow you to bypass the web server access?

Hey karl,
please try 854893 for Level3 Access.
You type it in over the Webbrowser.
If that doesn't work i can supply a flash firmware that is made with Webbrowser support for Parameter changement. It was designed for the 30s NMC Battery for the Fiat 500 Karabag.

Hey Jarl, Offcourse.
My old account is somehow blocked so here a new one.
I made a short video how to use the flashing script, the software is made for 30s nmc 100ah with the slave 5 originaly. You need to consult the manual to change all the parameters to your needs like but it helped me to change the high and low voltage Limits and the overall Energy of the Pack. What do you think, i try to upload them to github or am i alowed to upload the flashing file here and share the video on youtube?
I am open for suggestions, and i promise to controll the forum mor often for an answer from you
Greetings
