picked up a Z1 and went straight to rooting it.

rooted succesfully, installed the dualrecovery, and then attempted ot install VANIR only to realize that i did not unlock the bootloader.


so it will not turn on. holding power it vibrates every 2 seconds. plugged in it does teh same, but also blinks red.

i can get the computer to recognize it several different ways.
blue led- fastboot interface in device manager - not detected in adb devices
red/green/blank led - SOMC flash - no adb

PC companion is no go.
I have no idea where to go from here. I am currently downloading flashtool to see where that gets me, but I was hoping someone might have some direct and well known solution that i did not uncover in my searching..

Thanks

He will not be able to enter recovery because dual recovery is system based which he cannot get to as its now trying to boot a custom kernel with a locked bootloader.
Also the recovery on a custom kernel is in the kernel, which also cannot boot. Hence a bootloop with no chance of recovery mode

The solution should be easy enough
Flash a stock FTF for your device using flashtool

Look in the general section for a sticky thread called FTF mega collection for the best FTF file for you.

Once you have flashed that then you should* root, then unlock the boot following the official sony instructions (http://bit.ly/1cebNlh).
once you have done that flash the boot.img of the rom you want to flash using fastboot them flash the update.zip in recovery



*The reason to root before unlocking the boot is to backup the DRM keys in your TA partition. If you do not do that you lose them forever.
