Hello!
Given the tool in the subject, short history, I wanted to upgrade from version 15.2.7E2 to E5, but the webui part was not perfect (attached image). Then I thought I would revert back to E2 and now the device won't load. How can I fix the normal operation of the device now? Please describe in detail, I'm still a beginner ..
Another question, what is the difference between the .bin and .tar version firmware? For example, in the webui part, what do I need to do to update the system and keep the gui part?
Thanks in advance for your help.
