because in the RESET tab of the NLBA software i have seen that BQ3050 is treated as BQ20ZXX

 It is only applied for NLBA1 supported features. Like Unseal, Clear Errors, Read and Write eeprom. Yes, in this case you could use combined bq20zXXX, bq3050 plugin. But for advanced reprogramming TI software should be used.

I find this way faster :
- Unseal with NLBA > open BQEVSW and edit all Qcell > Edit Load Mode =5 >Send WW 00 0041 command (Soft reset & reseal)

Edit Load Mode =5

 Dont provide wrong advices. 

 Load Mode is set on the factory once and should not be changed. It tells the chip which load profile target equipment corresponds. 

Other steps you propose are not enough for proper chip reprogramming. 

Me recommend you to read TI application notes and datasheets to get basic understanding how chip works and how it should properly be reprogrammed.

 When "others" give any advices it does not mean those advices are correct. Because "others" basically ignore to read at least one TI application notes. 

 In order not to confuse our customers we will delete any wrong advices from the forum.
