Unbrick a device having broken volume rockers A technician checked my phone's (TCL S950/Alcatel One Touch Idol X) hardware and broke the volume buttons. I flashed TWRP recovery, because I wanted to install the latest CyanogenMod. The latter in turn bricked my device since it doesn't get past the boot animation. The volume buttons to get into Recovery or Bootloader don't work and ADB doesn't detect the device either.

What can be done to unbrick the device?
Since you cannot access fastboot without using the volume rockers or having access to adb: No, you cannot do anything else but repair your volume rockers or buy a new phone. If you want to repair the rockers, you can check on iFixit for a manual. They may have one for your phone.
