SPD tool for Zosi DVR reset (Free Download)

Here you can download the SPD tool for Zosi DVR reset. It's 100% Free.

The App is also known as "Zosi password generator app".

It's used to reset a Zosi DVR or NVR to the factory default settings.

I recorder a video with the step-by-step on how to use the SPD tool app when it was available in the Playstore. Later it was removed, so I wrote this article to help you with the manual installation, so you can watch the video and read the rest of the article to get the app installed on your Android phone.

The Zosi technical team informed us that there are no plans to have the app available again on the Playstore, so the alternative is to install it using the .apk file.

Here are the instructions on how to do it.
