I've been looking around the forum and couldn't find a solution for my problem
I bought a Xperia L for my child and based on my experienced with my Nexus 4 I wanted to install a custom Rom.
the phone is free sim. I 'm allowed to free bootloacker it.
After enabling USB debbugging ON and installing the drivers with flashtool (vers 9.13 on win 7 64bit) I managed to boot in flash mode and unlock the bootloader via flashtool (thanks to the key provided by Sony) .
the phone rebooted with the Sony logo and those coloured lights.AND USB debbuging OFF !!!!
I've tried to flash a original sony ftf (in put into the firmware C2105_15.0.A.2.17_CE or C2105_15.3.A.1.14_CE file in flashtool) but no luck. it tells me that is preparing the files and then reboot into "device" (usual reboot)
After removing the battery I've rebooted in fastboot and somehow managed to flash the custom Rom (.img) from Phantom (I can see his logo when I turn the phone on). but that's it.
I'm somehow suspecting the USB debbuging OFF creating me issues and the SD card being blank to not help either.
I've installed the PC companion lately but it does not recognized it either...
I'm quite a newby and my goals are 1st to have it working again then to root it in order to install a custom ROM.
Any help or suggestion is welcome
