[Rapsberry pi Zero] Green led flashing 8 times when powered on | no boot && no display

My Raspberry pi Zero has been delivered to night, but refused to boot ... stupefaction ...

I ordered this pi Zero + the NOOBS 8GB SDCard  from the swag Store, but when powered on, the green led was flashing 8 times, and nothing was displayed on the screen

After some googling, the "8 flashes" mean "SDRAM not recognised"

Apparently, my brand new NOOBS SD Card was not so "brand new", and needed some firmware updates

A a few copy/paste from the official 1.5 NOOBS image later (including bootcode.bin, recovery.img, recovery7.img, recovery.rfs, recovery.elf), I couldn't get it to boot past a kernel panic

I ended up formating and recreating the SDCard from a fresh "Offline and network install" NOOBS image (the NOOBS Lite "Network install only" does not detect my WiFi dongle and needs a "wired connexion" that the pi Zero does not provide)

Every thing now works like a charm ... happiness !!!

If you find a way to upgrade the needed files on the original NOOBS 8GB SDCard from the swap Store without formating, feel free to leave a comment

Happy Zeroing !!
