This is very common error in thumb impression/time attendance & door access machines, while this error appears, you will not be able to communicate with machine, via LAN or USB.
reason why this error appears, is built-in security feature,below in the image you can see a push button circled in red color.
Bio metric Attendance Machine
this button need to be pushed while fixing the back plate with wall, if button is not pushed the security system inside machine consider it as machine is broken, so to prevent data leakage, it start showing system Broken ! error message,
so if you want to get rid of the error, make sure you fixed the machine properly and that button se pushed.

Wanted to change my p40 pro to china version, contacted multiple people, some were promising free, some less money, but they didn’t share details. He was more upfront which I appreciated. I ordered harmony cable (Due to AliExpress shippers loosing it got it four months later) messaged him and he responded right away. Agreed on time (which was the next day), paid and after about two hours got harmony OS. Clean instructions when I needed to physically interact with the phone otherwise everything was handed by him. Some random might do it too, but he could also leave you with a very fancy paperweight.
Requested to change Huawei Mate Pad DBY-W09 (MatePad 11 Global) to Chineese version. All done within 2 hours. Great contact, great service, great support, 100% recommended! All done remotely via TeamViewer. Thank you Ministry of Solutions!
