Texas Instruments battery chips are very sensitive to wrong actions, hardware or software related. They are very easy to damage or brick but very difficult to recover. 

 Recovery tools are very expensive so it is easier to just follow simple rules in order not to brick the chip. 

 We have discussed these rules many times on the forum. 

In order to check chip condition, send these command 10x times and paste a log 

WW 38 0000 (10x)

WW 3C 0000 (10x)

@djibattworkshop

Error WW 38 0000
WW 3C 0000

 measure each cells voltage using multimeter, post values 

@djibattworkshop

@djibattworkshop I think fully charged cells may force chip to reset via NLBA1 or full reset enabled while its range to enable unseal ribbon

its not clear on the pictures what is cells voltages 

post values in text 

@djibattworkshop 

Cell1 3.58

Cell2 3.51

Cell3 3.57

Cell4 3.60

charge whole stack to 12.3v using external power supply in order to get 4.1v on each cell 

 it will allow to proceed to unseal board 

@djibattworkshop ok I will charge it 16.40v it is 4S1P

@djibattworkshop It did not work because it divided voltages and kept them lower than 2 volts for cell 3, which is not allowed by the NLBA1 reset functionality even cells are fully charged.

@djibattworkshop I have replaced the bq30423 chip from another 3Cell battery BMS and reprogrammed it for the 4Cell XCMRD. Now it is okay, but tough to satisfy the customer. Thank you as

Uber geek!!!

I wish one day I get to this level !

@exwilliam Hopefully, you will learn a lot from real Geeks (Moderators of this forum) as well Sir Nicusor using this forum

Those guys are monsters!

I wish they open some kind of certification courses.
