Looking for help please.
I recently purchased the 3B+ . Like most people I am also having problems with the SD card not reading and booting. Although I am new to this hardware and software I am extremely competent in reading/watching tutorials and following instructions. With that said below are the steps I have done and the issue I am having.
I set up my PI 3B+ as the instructions on the website and videos show.
I downloaded NOOBS, formatted a 32GB Sandisk Ultra SD card using the official formatting software and then copied the contents of the unzipped NOOBS folder onto the root of the SD card.
Inserted the SD card, HDMI cable, wireless mouse and keyboard USB and lastly the power (5v-2.4A).
Everything booted (showing red and green LED's) as normal according to the instructional videos.
I selected which software I wanted to install, the installation process started until the end where I believe the issue started. At the end of the installation the PI powered down which I thought was the reboot process after the installation. The issue is that the Pi never rebooted, it just stayed off with only the red LED on showing it was receiving power, this continued for about 5min. So I physically turned off the power and back on again and still did not boot but still receiving power.
Before I continue. I did try plug in a fan onto the Pi during the installation process. Could this be the reason for my Pi not responding?
So, I re-formatted the SD card and copied NOOBS over again and still no luck.
I then again re-formatted the SD card, downloaded Raspbian Stretch and copied the image (img) using Etcher as described in the forums. Still no luck...
I read all the trouble shooting posts and followed their instructions.
I connected only the Pi with a USB - USB to another laptop (pc) and the laptop recognised the Pi (according to STICKY this means the Pi is still good)
I purchased 4 new SD cards, formatted one of them and copied the Raspbian Stretch img and again nothing. Only showing the red LED as on.
with the 2nd one I re - downloaded the NOOBS zip, copied all the contents again only this time I never copied the recovery.cmdline as described in one of the trouble shooting topics. again no luck.
I have 2 brand new SD cards left and not sure what further steps to take and I am now reaching out to the community for help PLEASE.
this whole process has been done on a MAC which I don't think (hope not) is the problem. Should I try this process again using a windows laptop?
Is the Pi 'dead' and should I get it replaced?
Thanks in advance to who ever responds.
