How can I fix my Huawei Y300? Its not booting

A

AC Question

I tried to install a custom firmware on my Huawei y300, rooted it, but changed my mind and restored to factory settings instead from the menu.
It worked fine for a week, but I made the mistake that didnt delete the dload file from the phone. It doesnt boot since yesterday :/
I tried hard reset, and restored the factory settings again, but nothing happened.

- power button - appears the huawei logo than the screen slowly fading and than full black, i have to remove the battery
- hard reset again - after a few seconds the screen is turning to pink, and i have to remove the battery again
- via data cable - the computer sees the phone, but cannot open that partition, it shows error

does anybody have any idea what can i do?
