From here you can update your firmware, but when you connect the phone, it must be switched on and not in security or password screen. We will start "Support Zone" because from here we can flash the phone from switched off state regardless of whether there is a password. Now start "Phone / Tablet Software Update".

When PC Companion finished with update process, disconnect the phone and switch it on. Now your phone is in factory condition, with erased custom data and without password protection. .

Yes I did this successfully - thank you!

For those who, like me, had the "black screen of death" issue and Xperia Companion is telling you your device is locked, close down Companion, unconnect your phone from your laptop/tablet and start again using the instructions above. If you do this right it lets you bypass the locked screen. You have to do everything in the order above otherwise it won't work

My device is bricket, from Sony to Xperia in a loop... When I connect it to a PC... it connects for a moment (As Flash) and starts the loop, as if you had started the device. May I connect the device without battery? Thanks
