Unable to factory reset C3850 Switch

[Mike ITSS]

I have multiple WS-C3850 switches that are all having the same issue. All of them have read only mode on the flash for ROMMON and are unable to boot at all. Here is the output when trying to boot and all dir names.

switch: dir

List of filesystems currently registered:

xmodem[0]: (read-only)
null[1]: (read-write)
bs[3]: (read-only)
usbflash0[10]: (read-write)
flash[19]: (read-only)
tftp[20]: (read-write)
ftp[21]: (read-only)
http[22]: (read-only)

switch:

The system is unable to boot automatically. The
BOOT environment variable needs to be set to a
bootable image.

Tried multiple different ways to attempt to fix it but I have no idea how as i'm new to this, any help would be appreciated.

Hello @Mike ITSS,

Please do

dir flash:

And share the output.

IF the switches are still in ROMMON, post the complete output to the following commands: 

1. dir flash:
2. set

[Wizard4777]

When the switch goes into rommon, Issue the dir bootflash: command to list the files present in the bootflash, or issue the dir slot0: command to list the files present in the Compact Flash device.

          rommon 1 >dir bootflash:
          rommon 2 >dir slot0:

The reason the switch reboots continuously is because the system image file name specified does not exist, but there is a valid file in the bootflash and slot0:. Also, the system image file name specified is case sensitive. If it is not specified correctly, it causes a continuous reboot.
