-===== Raspberry Pi 3 Model B+ does not boot ===== +
-If these conditions obtain: +
-  * booting for the first time on this hardware +
-  * using the Raspian OS upgraded on Raspberry Pi 3 Model B (without the +) +
-then it's likely that the boot disk doesn't contain the requisite firmware. So upgrade NOOBS. +
-  * Download [[http://downloads.raspberrypi.org/NOOBS/images/NOOBS-2018-03-14/NOOBS_v2_7_0.zip|this NOOBS version]] +
-  * mount 1 partition of the SD card +
-<code> +
-sudo mkdir -p /media/pi/MMC_P1 +
-sudo mount -t vfat /dev/mmcblk0p1 /media/pi/MMC_P1 +
-</code> +
-  * delete contents of partition 1 +
-<code> +
-sudo find /media/pi/MMC_P1 -mindepth 1 -delete +
-</code> +
-  * unzip NOOBS into partition 1 +
-<code> +
-sudo unzip /home/pi/NOOBS_v2_7_0.zip -d /media/pi/MMC_P1 +
-</code> +
-  * remove //runinstaller// +
-  * sudo nano /media/pi/MMC_P1/recovery.cmdline +
-With //runinstaller// removed, the line should look like this +
-<code> +
-quiet ramdisk_size=32768 root=/dev/ram0 init=/init vt.cur_default=1 elevator=deadline +
-</code> +
-  * shutdown +
