Xperia M software update failed 15.1.C.2.8

[shantanu198]

Today I got a notification stating new software release for the phone, 15.1.C.2.8. I downloaded the updated and tried installing. Phone restarted, as mentioned, however I got a popup message saying install failed. I tried this twice, did not work.

I was on WiFi at that time. 

What could be the issue? And if possible, please let me know or give me a link of changelog for this version

[bang]

maybe you will try update with pcc or sus

it's work for me..

several people report the issue about battery drain quicly and getting hot.

but i like the new semi transparent statusbar and nav bar.
