content: Hi guys,I have a SDG830 and recently I tried to update its firmware, but after the update finished and I rebooted the SDG830, it froze on the logo screen.I emailed Siglent, and they sent me USB recovery files, unfortunately the files didn't work.Other similar posts suggest asking tautech for help. But it seems that tautech accepts PMs only, and I can't send PMs because I'm new to the forum here.So, are there any solutions?Any help would be appreciated.

content: Dear tautech. Could you please provide the necessary firmware files or recovery instructions to restore the device's operation? We need a recovery method using an SD card, with opening the SDG830 device and installing 2 solder jumpers. The recovery method using a USB drive does not work.Thank you in advance for your help. I look forward to your prompt response.Best regards, SergeyMy email: sergei.jmails@gmail.com
