Hello,
I have a Sony Xperia XA2.
When I try to update to 5.1.xxx, the system warns me that I only have about 730 MB of free space in the system partition instead of the required 770 MB.
So I can’t update the system right now.
Will there be a change soon so that this amount of space is sufficient?
If not, I wouldn’t like that at all!!
So, they increased the necessary space a bit after the first people updated, so its possible 730MB is enough. BUT TRYING IF THIS IS RIGHT CAN BREAK YOUR PHONE: if you can deal with this you can try to update from commandline (and if you don’t know how, than you really shouldn’t do it…)
But 40MB is not that much, perhaps you find a hint here (How to free space on the root filesystem (before an update)) to make that space free on your device.
As the 5.1 release contains a lot of updates to system base packages, I don’t think it’s very likely we’ll see a version that could manage the update with less free space available.
Once you are on 5.1, the space required for OTA updates (i.e. from 5.1.xxx to 5.1.xyz) is likely be lower as the update footprint is much smaller again.
No.
There is a whole thread on freeing mor space in the root partition. I would not try to force an update on the cli in this situation.
The simpliest way would be to reflash the device. Then you have the new and bigger root partition size for the future, @softfriese .
edit: when was the device flashed last time?
Changing partition size is possible but very complex, and risk is a bricked phone. Flashing new is about half an hour and easy.
