OTA upgrade 2 to 2.41 failed. PI cant be seen on network


Tried the OTA a few times since I set up my pi b+ with the volumio 2 but it’s never had an update. Yesterday it said I could upgrade to clicked on upgrade. I left it and it got to 60℅ and went no further after about 1 hour. It just dropped the network connection and hasn’t been contactable since. I have rebooted just in case but nothing.

I can’t ping the pi or access the web browser.

I didn’t want to start again as I have my own web radio stations URLs and the connection to my NAS that I will lose.

Before I delete the SD and start again, is there anything to save this current version and get it back on the network ?

I’ve seen a couple of posts yesterday about faulty upgrades.

Thanks in advance
