problem installing wifi-qcom-ac package on hAP ac^2

I have a problem installing the wifi-qcom-ac 7.14.3 package on my hAP ac^2. The problem is as follows:

And with the wireless package uninstalled I have 12.9 MB occupied according to the files tab. The system itself weighs 11.2 MB in the version 7.14.3 I currently have installed, so it’s no surprise that the package with the new WiFi won’t install with me, as it weighs 2.85 MB. My configuration, after expiration, has 264 kB. What else can take up space ? Bookmark “files” is empty. And resetting the router to factory without keep config and trying to install the package doesn’t do anything.The disk space is the same.

Of course, I try to install the package from the correct architecture, that is, arm.

Thank you in advance for your help.

7.13.5 or 7.15rc1 to regain free space.

Thank you very much ! Version 7.15rc1 solved my problem. I couldn’t roll back to a lower version because this device is located in another city and I was doing a remote update.
