If I were you I would start from the beginning. My experience in general when something is put together and taken apart several times to troubleshoot it can create new problems on its own.. Like bad connections.Ok so after knocking off the old 10x2400mah mismatch cells, now I can't get the 10s2p configuration to work with the new cells.
After some troubleshooting seems like the BMS failed once again! Spoke to the vendor who says its in standby mode . Returning the BMS to the vendor. Please watch the video of my troubleshooting for more information.
I did try charging the battery pack as advised, but that didn't work.
Some noob tips to disassemble the kit:
1. You can use a tire lever(fiber) to lift the end caps and pop them out safely without the fear of shorting.
2. A heat resistant tape works fine to hold the contacts while testing the incomplete battery pack.
I would measure each cell for resistance and voltage and charge each individually to its nominal voltage of 3.60v

8.5. Mixing use
8.5.1. Different types of cell, or same types but different manufacturer's cell
may lead to cell rupture or damage to system due to the different
characteristics of cell.
