CSCut90593 - 2960X crash during boot up with Error ASIC/PHY POST failed - 7

Hello, I have a Cisco ws-2960x-48tl-s switch. I am trying the iOS update from "c2960x-universalk9-mz.150-2.EX5.bin" to new versions and I getting this error:

...

POST: PortASIC Port Loopback Tests : Begin
POST: Failed PortPhyLoopback Packet Test asic_index 1 port_hardware_index 21
POST: PortASIC Port Loopback Tests : End, Status Failed

Error: ASIC/PHY POST failed. Cannot continue

%Software-forced reload

...

The result is the same even though I tried the suggested solutions(update suggested iOS versions for this bug, hard reset etc.).

Any other suggestions?

Thanks.

Cold Reboot:  Pull the power cable.

Hello Leo, I disconnected and reconnected the power cable on the device but it has not changed, i keep getting the same error.

Is there a specific time to disconnect the cable, like during post tests or before post?
