Unexpected error 9 iTunes

I have an iPhone with cracked glass that don't power-on (even backlight).

If i simple connect to iTunes, i receive the message that a restoring is required (recovery mode, i can see the IMEI).

I've tried restoring it in DFU, recovery mode, and both ipsw firmware iOS 9 and 10, all with the same result - iTunes keeps throwing error 9

Also noticed that if i keep the iPhone just connected to the PC (without doing anything), it will disconnect and reconnect automatically every certain amount of time.

I've also tried this solution: How to fix iTunes error 9

With those results:

- Reiboot (http://www.tenorshare.com/products/reibo...) = Stuck at "Exiting from recovery mode, please wait..."

- i4Tools (http://www.i4.cn/) v.7.10 = Error at 15% (Step: NORData)

Any ideas/help would be appreciated.

Thanks in advance.
