I try to boot it without USB stick many times, then i change the USB stick (replace the old one with new one), but it doesnt solve my problem. Could you help me? This is the information from my status page: Bad Firmware Signature What does this mean? The probe's firmware signature is wrong. How can I fix this? Power-cycle the probe and wait for a couple of hours. If probe doesn't come online you should try to reinitialise or even replace your flash drive. Please use the following procedure: <ol style="box-sizing: border-box; margin: 0px 0px 12px; padding: 0px 0px 0px 20px; list-style-type: decimal; color: rgb(51, 51, 51); font-size: 14.3px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;"> <li style="box-sizing: border-box; display: list-item;">Unplug the probe from its power source</li> <li style="box-sizing: border-box; display: list-item;">Remove the USB stick from the probe</li> <li style="box-sizing: border-box; display: list-item;">Plug in the probe WITHOUT the USB stick</li> <li style="box-sizing: border-box; display: list-item;">Wait for ten minutes</li> <li style="box-sizing: border-box; display: list-item;">Insert the USB stick</li> </ol> If it didn't help repeat these steps using another working USB stick that is at least 4GB in size. NOTE: This must be done on a network with working DHCP! It will NOT work if you have configured your probe to use a static IP address, because this mini-operating system does not have access to any statically configure IP addresses or DNS resolvers. If you have configured your probe to use a static IP address, the only thing you can do is move it to a network with working DHCP. When the probe is listed as "connected" again, it is safe to move the probe back to its original location. However, please note that we advise configuring your probe to use a static IP address only if you feel it is truly necessary to do so. Thx, Jiri </body> </html>
