Update / re-flash your Raspberry pi 4 eeprom
Your pi 4 does not boot ?
Or you want to upgrade it to add a new feature ? (No new feature yet 19/07/2019) but some rumors about an update to low the temperature … If you have more information tell me 🙂
So, first, go to Recovery section of the download page and hit the « Download the bootloader » link (I do not add a direct link here, to avoid linking to an old release)
Next, follow the steps:
2 – extract to an empty fat32 formatted sd card (every old card will do the job)
3 – Plugin into your Raspberry Pi 4 and wait until the led flashes
If it’s not working, you can:
- download again and extract again the files
- format again the sd card
- change the sd card
- double check the power supply (use the official one, or some of the very good quality vendors, do not use cheap power supplies … You have to use a « dumb » cable because of the issue in the USB-C connector on the raspberry pi.
