Deleting carrier boot animations

[phantom2000]

I have Sony Xperia U. When I boot the phone, the SONY boot animation comes in and after that, a boot animation from the carrier comes in. I want to keep the SONY animation and remove the carrier animation. And also when I turn off the phone it comes in again. I want to remove all the startup and shut down animations from the carrier and only keep the animations from SONY. How can I go about this? My phone is rooted.

There are ways to do this but its a lot easier to flash the global generic firmware

I do not want to upgrade the phone to ICS. It's on 2.3. Would you be able to tell me how to do it without flashing?

[Uliwooly]

Check the above link on the downgrade section it will have 2.3 firmwares

If I flash the phone using this, Xperia U_ST25_6.0.B.3.184_Global_Generic will that do the trick?

Yes it will, it will delete those "Network/Carrier" preloaded apps and any network/carrier boot animations

Nice. Thanks. I'll try that an let you know you guys.

I was wondering, this is the official operating system from Sony right?

[Uliwooly]

Yes its official firmware, there are myriad variants of each update for specific countries, regions, carriers/networks

Hi, could u please help me with this same problem? I have a different Sony but same problem, I want to delete those carrier's animations. The fact though is that I'm not rooted, so I might use adb instead.

Thanks
