CFE 5100 and Smart BESS - cannot connect

I have two CFE-5100 batteries and Deye invertor. I have replaced the batteries with Seplos Mason 3 and it works great. Now I want to donate my CFE-5100 to someone else, but before that I want to "train" then - charge without invertor-BMS communication with 57.6V until BMS shuts off, then balance with slow charge until the cells are equalized, then discharge until shut off, then charge to some % with BMS communication. Then repeat the same with the another CFE 5100, at the end charging to the same %. Hope then 2 batteries connected in parallel will last longer.

My problem is that I cannot monitor CFE's status (especially individual cells' voltage) as I cannot connect Smart BESS to the battery. Per instruction, there should be WiFi SSID hiflying_softap, but there is no such SSID. When I switch on the battery, I see HF-LPD130 hotspot, but when Smart BESS android app connects to that hotspot, it tries to configure the battery but that process never ends. Somehow I managed to install Smart BESS, now I have newer android phone, but Smart BESS is not available in Google Play for me. I think app got transferred to my phone from the old one. Or maybe Google Play banned that app. When trying to download apk from CFE site, I got wrong certificate error, and decided not to continue. Maybe there is another program which will communicate with CFE-5100?
 
This document says I should set all DIP switches to OFF and hold Reset button for 3 seconds until the Run button flashes. My Run button does not flash, I remember on one of the batteries it was not working at all, but the battery worked fine (accepted and delivered the energy, communicated with the invertor). Anyway, there is no hiflying_softap SSID, and HF-LPD130 also was not available.

Per this document, there is CFEnergy app, but Google Play knows nothing about it. That document says hold reset button for 2 seconds (vs 3 in Smart BESS document mentioned above), but to no avail. Anybody successfully monitored CFE-5100 from their phone or PC?

BTW video on CFE site says hold reset for 7 seconds :) But they show 5100S battery, maybe mine is older and behaves differently. Theirs is white, mine is black.
