Smile About Baseband :)
Hi dudes I come here today because I have some questions about how to flash the Baseband -36 in a Xperia Play R800a. In this moment I have Baseband -66 and when I tried to install with flashtool the FTF of Baseband 36 it crash and show me this log.

I need it to use DoomKernel because it drain my phone too quickly

I can use fastboot perfectly, can I flash the baseband with Fastboot? Thanks for your help!
