BG95-M3 Old SW BG95M3LAR02A02 upgrade trouble


I tried to upgrade my very old SW with QFlash4.19 but in vain.
Is it possible to update it to a new version like BG95M3LAR02A03_01.014.01.014 or even to an earlier version ?
Which Qflash version shall I use ?

Thanks for your help in advance,

Best regards,

Flavian B

Solved. I have choosen file “partition.mbn” in “\update\firehose” subfolder
