[SOLVED] No Boot Light Blue Only


Hi, I’m not able to start up my printer, after switch on the logo starts to blink in light blue but it never switches to the white operation mode.
Till yesterday all was working fine but, after a normal switch off, it can’t boot now.

Please help me with this issue.

Hi, anyone has a system image file of Flux Delta+ SD?

Thanks for help



I had the same thing happen me and when I plugged a display into the raspi it was clear the sd card was corrupted. I opened a ticket and flux posted a disk image after a couple of days and I was back up and running.

I have the boot image for the Delta but not the Delta+…sorry :frowning:


HI Raj, they send me an image file, I have tried to flash it using different SD and different SO (Win, MAC) but without success.

The image file (7.4GB) seems to be broken; I’m saying this because I have also flashed an SD with normal RaspBerry image and the board startup normally.

Any help is very appreciated.



hmmm…apparently I don’t get notified by this forum :sob:

I vaguely remember the issue but I recall seeing a bunch of the usual I/O errors on mmcblk0 from the raspberry pi. Which version of the file did they send you?
Flux sent me rpi-201604023-1.0b20.dmg which I flashed to the sd card with dd, I don’t recall having to do anything else.

Good luck and keep us posted!


Hi, they send me this file Delta_1_0_b20.img.

I have tried to flash it using dd on Mac and Linux and using Etcher and Win32DiskImager on Win.
No way to get working SO.

I also have checked the file; the result is:

fdisk -lu /media/root/Macintosh\ HD/Users/myuser/Downloads/Delta_1_0_b20.img

As you can see the image’s content is wrong.

Is there any way for me to get your image file?
