+Raspberry Pi 4 EEPROM bootloader rescue image
+*********************************************
+
+The Raspberry Pi4 has a small EEPROM used to store the bootloader.
+
+This rescue image reverts the bootloader EEPROM to factory default settings.
+
+This rescue image also updates the USB 3.0 (VL805) firmware to the latest
+version (138a1) with better full-speed Isochronous endpoint support.
+
+To re-flash the EEPROM(s)
+
+1. Unzip the contents of this zip file to a blank FAT formatted SD-SDCARD.
+2. Power off the Raspberry Pi
+3. Insert the sd-card.
+4. Power on Raspberry Pi
+5. Wait at least 10 seconds.
+
+This easiest method for creating and formatting the SD-CARD is to use the
+Raspberry Pi Imager from https://raspberrypi.org/downloads
+
+If successful, the green LED light will blink rapidly (forever), otherwise
+an error pattern will be displayed.
+
+If a HDMI display is attached then screen will display green for success
+or red if failure a failure occurs.
+
+N.B. This image is not a bootloader it simply replaces the on-board bootloader.
