Copy the hash to a Base64 decoder (many online tools, or use echo "hash" | base64 -d in Linux). Part 4: Method 2 – The Physical UART Unlock (Hardcore) If the software backdoor is patched (ISP has disabled telnet and CGI exploits), you must go physical. This voids your warranty and requires soldering.
In the world of ISP-provided hardware, few devices spark as much frustration—and hidden potential—as the ZTE ZXV10 B866V2 .

Since the output is too fast to read, copy it to a USB drive or use grep to find the password:
