I have a 3850 that cannot seem to boot up. I tried booting from USB. I tried booting with SWITCH_IGNORE_STARTUP_CFG. It gets stuck every time with the error below when it tries to launch linux kernel. I believe one problem is that the flash is full but I don't seem to have permission to delete any files. What I remember from Linux, -rw means it is a file that I should be able to read or write. This switch is just stuck with the error below and I can't seem to affect anything.
switch: dir flash:

Are you sure you want to delete "flash:-Mar-28-08-55-22.354-PST-0" (y/n)?y
File "flash:-Mar-28-08-55-22.354-PST-0" not deleted -- read only file system
This is where the boot process gets locked up:

Hello
Try the following and see if it boots
boot flash:packages.conf
if successful then change boot variable on the switch to point to that file and save changes
no boot system
boot system flash:packages.conf

That's a no-go. It got stuck at the same point.

Have you tired a different iOS version?

- Try fsck flash: (include the double column).
