Redmi2 Pro Always Bootlogo

[isthevene]

Hi guys, my redmi2 is completaly dead... when i tunr it on there is always the bootlogo and i can't swich it on with the recovery but only with fastboot.
I tried to flash with miflash it didn't work (it flash very fast, like 1/2 seconds, and say flash success but it doesn't reboot and if i try to remove and replace the battery it always stay with the bootlogo), i tried to flash with minimal adb but didn't work (the devices list is empty), i tried with mipcsuite but it can't find the device.
What can i do? I tried a lots of guides but they didn't solve the problem. Can you help me? thank you

Have you trie to flash in fastboot mode.?

yes... today i booted the twrp (i don't know why if i flash it, it doesn't work) and i noticed that the file system cache and data size is 0mb and if i try to wipe everything it appears the error "can't mount /system/data/cache"...
I tryed to change file system, to wipe data and cache with minimal adb, i've tryed everything but it doesn't work anyway...
