- These kind of 'hardware interventions' are not supported , post the startup process (console) , but your controller will probably need replacement (RMA)

- The flash is corrupt , I don't think it can be recovered , you could confirm this with TAC (e.g.)

Marce is correct - you cannot recover from this yourself - your only option is to contact Cisco TAC and that will probably require RMA.

Did you make sure you updated CIMC and firmware on the WLC before trying to upgrade as per https://www.cisco.com/c/en/us/td/docs/wireless/controller/release/notes/crn810mr9.html#cimc-upgrade because that addresses some bugs which can cause this type of problem?
