Attempting update from 2.3.4 to 4.x and the pc companion software keeps telling me my phone is up to date! Anyone know if it's possible to do a manual install?

  • what year is your handset?

  • 2011. Last September - it's SI is one of those listed as eligible for an update. I'm guessing it's something to do with my network T-Mobile in the UK?

  • FYI - I was constantly refreshing the sonymobile's page to see if my 2011 ST15i's SI number showed up. But no, it did not, it was when I checked Sony's PC Companion suite for an update itself, then after the software got updated, it recognized that the ST15i was eligible for upgrade to ICS.

You can manually install update using Flashtool,and also you need ftf file for it,

  • That will not work unless the boot loader is unlocked!

  • You do not need unlocked bootloader for it.
