Hi, I recently checked if there is an update for NSPanel Pro. The latest version is 4.0.12 I tried to install it but got an error message saying there is no space available. When I checked I found that I would need to delete some update .zip files of old versions: 4.0.0, 4.0.7, 4.0.10 etc. When I tried to delete any file I was asked for my password! What password is this? What files can be deleted? How can I fix the problem? Thank you. ![20251102_221302](https://europe1.discourse-cdn.com/flex005/uploads/ewelinkforum/original/2X/1/1be20b84b7895703d47cfc76c8db6057d023a19c.jpeg) ![20251102_221241](https://europe1.discourse-cdn.com/flex005/uploads/ewelinkforum/original/2X/7/7b698a809bdc124f1bb8272ead86cee06df258de.jpeg) ![20251102_221142](https://europe1.discourse-cdn.com/flex005/uploads/ewelinkforum/original/2X/5/5cc1a568e052d4e10aad80541a32e79110963dc0.jpeg) ![20251102_215458](https://europe1.discourse-cdn.com/flex005/uploads/ewelinkforum/original/2X/e/e9252db2b7929173a5b3b219539f2e17272e64d8.jpeg) ---

Hi, sorry for the issue. There is a bug in previous and current v4.0.x firmware which doesn’t delete used OTA files. So after several update, these unnecessary OTA files have occupied a large amount of storage space. You can follow the steps below to clear these OTA files. As a side effect, you will need to reconfigure your NSPanel Pro after that. _Note: `Reconfigure` only involves `Language Setting`, `Country Setting`, `Custom Wallpaper`, `Custom Ringtone`. Zigbee network, Wi-Fi etc., remain intact._ ![1](https://europe1.discourse-cdn.com/flex005/uploads/ewelinkforum/original/2X/0/089a69296f3828f39deea0bd7fef02f2d5737356.png) ![2](https://europe1.discourse-cdn.com/flex005/uploads/ewelinkforum/original/2X/7/7381c13fcd4e8849043e2e0035ffd861ce672224.png) ![3](https://europe1.discourse-cdn.com/flex005/uploads/ewelinkforum/original/2X/7/770848d5c285e2c7a80bbd33963c30263de87c8a.png) ![4](https://europe1.discourse-cdn.com/flex005/uploads/ewelinkforum/original/2X/d/d62399964e22c1cd8ae5eb91a61da8ce2b1495f4.png) ![5](https://europe1.discourse-cdn.com/flex005/uploads/ewelinkforum/original/2X/1/1963ef39b34176fc01d93a916f083cebb7c3f94d.png) ![6](https://europe1.discourse-cdn.com/flex005/uploads/ewelinkforum/original/2X/b/b1843e50bf3194f0df17e8e2d8cd37fd38e9dfc7.png) ![7](https://europe1.discourse-cdn.com/flex005/uploads/ewelinkforum/original/2X/2/244881312b2ead3a82673ec22e20744a6ceaab87.png) ![8](https://europe1.discourse-cdn.com/flex005/uploads/ewelinkforum/original/2X/6/6b931f769959b97296f7bdf9efaaf8e70202e55a.png) ![9](https://europe1.discourse-cdn.com/flex005/uploads/ewelinkforum/original/2X/f/f83fc764e607ef7c5157bf4f26c79a6b7933d41a.png) ![10](https://europe1.discourse-cdn.com/flex005/uploads/ewelinkforum/original/2X/8/8195b634e795c5c805daf7f3dbf116e0c21cdcdf.png) ![11](https://europe1.discourse-cdn.com/flex005/uploads/ewelinkforum/original/2X/7/7702629848dbd855d764f6ed5650a0b90fa18ab0.png) 1. Install `Fossify File Manager` through F-Droid (`Top drop-down menu -> F-Droid -> Latest -> Search "Fossify File"`) 2. Open `Fossify File Manager` and press bottom tab `Storage`. You can see how much storage space is left. It should be 1.8GB at least in normal operations. 3. Press the number of the free storage, scroll to `Other apps` and press it. You can see the list of installed apps and the storage space they occupy. `NSPanelPro` App should take no more than 500 MB. In your case, `NSPanelPro` App is possibly occupying more than 1 GB storage space. 4. Press the name of `NSPanelPro` App, and then press `CLEAR DATA` button to recycle storage space. You will notice the `AssistiveTouch` button on the top left side is gone, because `NSPanelPro` App is stopped in order to clear its user data. 5. You need to power off NSPanel Pro device in order to reboot into Home screen again. Please let me know if above method solves your issue. **PS: As a last resort, you can always do a `Factory Reset`. The cost is a bit high. You will need to do all the configurations again, including re-pairing Zigbee devices.** ---

Hi, for those who aren’t already in this situation, are you planning an automatic solution? For example, a new version that deletes old firmware files? Thanks. ---

Hi, if you’re unable to install the app, it might be due to insufficient storage. The last resort would be to factory reset the device (please note: after doing so, all existing devices and settings will be lost).
