Hello

I plugged my µ-sd (card that is running fine on my RPI3) into my new RPI 3 B + and it does not boot (rgb square screen)

is it possible to tweak the files on the µ-sd card to make it boot ?

thanks

If not already done .... use you RPi3 to update the software on the SD card then try it in the RPi3B+

sudo apt-get update
sudo apt-get dist-upgrade

(assuming that your SD card already has Raspbian Stretch on it)

so it should work? I mean I'll update the dist, but technicaly speaking they are the same architecture

I was wondering if my rpi3 b+ was damaged...it's brand new

Yes it should work, but not until you update the sdcard contents. PI3B+ has some hardware changes besides "it's the same architecture" so new firmware is needed.

Additionally, the rainbow screen you are seeing, is completely normal behaviour. It is supposed to show that every time you boot it.

In affect, the SoC has a different part number, the Wireless chip and the ethernet chip have both changed, and there is now different power management on board. So lots of things that require modifications in the SW to run them. Hence the requirement to update.

However be aware that it can be disabled in /boot/config.txt.

Hi, same problem here.
I did update and upgrade but I still can't boot.
Did it fix it for you? Have you found any workaround? Thanks.

The easiest solution is to download the latest NOOBS or Raspbian and put it on a card. Either a new card or your current one.

No, it just needs new firmware. The architecture is the same, but there are some hardware differences that require a firmware update.

Are you running Raspbian Stretch or Jessie (or... :shock: Wheezy)? You need at least Raspbian Stretch for the new Pi3B+ model.

And if it's Stretch, was it originally installed from a Stretch image, or did you upgrade from Jessie?

I am with Wheezy.
I did rpi-update, then I could boot normally. But the wireless/wifi is unavailable, like in this post.

I couldn't find any solution yet.

Raspbian Wheezy and Jessie are both end of life.

Raspbian Stretch has been the supported OS since August 2017.
