ZTE Skate - recovery to stock doesn't work

[Guest Blyler]

Hi, like the title says, i tried to root my smartphone, but because i surely did something what i shouldn't, android isn't going to boot..

When i turn power, it shows green android logo, then blue inscription ANDROID and then it start just flashing it again and again and i can't do anything..

I tried even recovery mode, but it looks like something is broken there, i wiped all data and cache, then rebooted, but nothing, so i ask if you would be so nice and at least try to help..

Btw.: USB doesn't work too, shows some unknown device in PC, no more, can't manipulate with it.
