S7-1200 all status LED blinking

Hi,

Yesterday I was uploading a program to the S7-1200 (FW 4.2), when suddenly the three (3) status led start to blink (run/stop green yellow, error read and main yellow). I search for it on the manual where I found it is an firmware issue. I tryed to download the firmware again using TIA 14 but the PC cant find the plc by IP. I also tryed to search for the PLC using Primary Setup Tool to assign a new IP to the device, with out luck.

I also seach around the internet looking for any hint to solve ir, once again, without luck.

Could you guys please help me to solve this problem 

thanks for your kindly support.
