Hello guys i had the (chain[5] PIC need restore ... ) error and fixed it by using the IP Reporter Firmware restore, you can find it in Bitmain's Forum but i leave it here for all of you

IP Reporter Restore (The miner will automatically revert to factory default firmware)

This method is only applicable to the miner as below. (The SD card slot of the miner should be on the left of Ethernet interface.

Usage: Please power off the miner, then hold down the IP Reporter and dont release it. At the same time, please power on the miner. Releasing the IP Reporter after 5 seconds, the machine will automatically restore factory settings.

NOTE: This method is not applicable to the miner which has a SD card on the right of the Ethernet interface.

After i did that the pesky PIC error just went away.

This is just a method to do a factory reset this sometimes works but not all and you are just copy pasted the guide from bitmain support without credit.
Anyway, you can find this method from here "How to reset miner to factory settings " credited to bitmain.

This is just a basic solution but if the restore factory reset doesn't work you can try the method below.

The method to fix this issue if you have PIC error is to flashing it with PICKit 3 which is tested by some miners out there.
