In this video, I explain how to recover from the dreaded reboot loop these like to do if you don’t upgrade the firmware exactly right on a Cisco IE 2000. The error you may see will have the line "Error Stat’ing code:jeevesfpga.rbf." This is recorded on a phone, so quality may be lower than normal.
Make sure the SD card is formatted in FAT format (no FAT32, NTFS, exFAT or any other cool file systems, pretend its 1992) and is under 2GB.
Commands to use once SD card is inserted.
flash_init
copy sdflash:/jeevesfpga.rbf flash:/jeevesfpga.rbf
