BT Home hub 5A doesn't save settings

Hi can any

device has 128mb ram and flash
New Bitmap Image (4)
New Bitmap Image (3)

That would be an issue with your particular installation/ device, not the BTHub5 in general (which works just fine). Before digging much deeper, I'd suggest to do a fresh new upgrade without keeping settings (19.07.7 or 21.02.0-rc1; let the device 'rest' for about 5 minutes after the flashing and before trying to log in) and debugging in a dedicated thread from there on.

This thread is about devices with insufficient amounts of flash (4 MB), which just manage to build in 19.07.x, but no longer have enough free space for the overlay (while you would have over 100 MB at your free disposal, if everything worked out).


Having reinstalled the previous upgrade 19.7.07 the config save problem is resolved. just to check i installed the latest snaphot on top and the problem comes back. there may be a problem with the snapshot?. is it possible there is an issue with partition size or something as /dev/root shows 100% and 0 % available.

Also i'm relativley new to openwrt so is it possible to resize root on the fly as with Linux.

Kind Regards.
