You might find a solution here. What I would first try is to go into Fastboot mode. Then I would flash the stock recovery ( Jelly Bean[4.2] or Kit Kat[4.4] ). Afterwards i would download the firmware you want, put the update.app in your dload folder on your sdcard and flash it over stock recovery.

So 1. step:

Entering Fastboot mode with the help of the buttons on your phone

Press and hold VOL - and POWER button and your phone will enter fastboot mode

2. step:

What is stock recovery IMG ?
Depending on what firmware you want to install, Jelly Bean or KitKat, you have to install the correct stock recovery.

You can find a complete guide here

Download links for the images:

Here is the link for the JB stock recovery IMG (B118) and

Preparing the firmware for flashing

Unzip you downloaded firmware and put the UPDATE.APP file into the dload folder of your sdcard. If you don´t have a dload folder you should create one.
