[Sony Xperia Z Ultra] Charles_064:
Hello xda, I have an XZU (C6806) and was trying to restore the OS with Pc Companion. As my phone had less than 15% of battery the program didn't let me do the process, it said I needed at least 50% so I charged my phone up to 61% and tried to restore, the program (PC Companion) kind of started the process and shutted down the phone. Right after that a window poped up and canceled the process because I needed 80% of battery so I tried to power up my device but it will only show the SONY logo and then some text that reads "The software update failed. Make sure that your phone is connected to the computer and try again." I plugged it to the computer but Pc Companion wont recognise it.

I tried with this guide..

At the end of the guide it says I should try to boot and flash my device normaly. But I'm a bit noob and I don't know what to do, I don't know if the process worked or how sould I flash my device because I can't enter recovery or anything else. My phone is still the same. Also, in the guide it says that the device should apear as "SEMC Flash Device" but mine apears like "SOMC Flash Device". I dont know if this makes any difference on the process.
