2D42 : firmware upgrade to 2021090901 -> scope does not work

Hi,
I’ve just updated my Handtek 2D42 device to firmware 2021090901 and the scope is not functioning correctly anymore. When I set Channel 1 to 1V/div DC coupling and I plug to a 3.6V DC signal I see a negative value which does not correspond to my signal.
I’ve tried to trigger on a signal with the same settings as before upgrading and it does not work anymore :(
I’ve seen on the forums that people have had strange behavior after upgrading …. Any known issue with this firmware ?
My PCB version is 100000000001 FPGA V02
Thanks for your help

Hi,
since I've got no reply to far, I'm wondering how to get access to previous firmware versions so that I can roll-back . So far I've not been able to find an archive repository ... Anyone knows where to find this ?
Thank

I have a firmware, HTX2020070701.dfu, for 2D72.It may or may not work for your 2D42.but I haven't seen any different firmware/software for different 2000 series scope meter.

Just not sure how to share it.
