About me


XPERIAfirmware.com is here for few years and there were more than 10 000 000 visitors, which is amazing number. In 2018 we create completely new site with better user interface. We update all articles and adds support for latest Sony XPERIA smartphones.

My name is Jozef Cmar and i am from Czech republic. I started with videos about Sony (Ericsson) XPERIA smartphones few years back (from Sony Ericsson XPERIA X10) and now my XPERIA YouTube channel has over 53 000 subscribers. But there was no dedicated place for firmwares, so i create XPERIAfirmware.com. In January 2018 we finished completely new site and we update all articles, so now we support all smartphones from Sony Mobile. If you want to support this project, you can donate with PayPal (jozef.cmar@gmail.com) or just subcribe to our XPERIA YouTube channel. XPERIAfirmware is unofficial site dedicated to Sony XPERIA products and we don’t have support from Sony Mobile. Products names found on this website are trademarks of Sony Mobile Communications AB.
