Tying to install TeamBlue 6.4 but stops on boot at 49

Hi, I installed this image from here (https://images.teamblue.tech/6…00seplus-20210227_usb.zip) but is not working and after flashing the boot gets stuck always at 49 on the frontal display.

I also put the latest bootloader for this receiver form here: GB HD 800 se + 128MB 24/07/14

D.o I need to do something else?

Thanks.

Sorry... I have both receivers, that's why I post on the Gigablue HD 800 SE plus forum my question.

Just tested now with TeamBlue 6.3 and works without problem.

So I tryed from inside install the 6.4, all went ok, but on reboot got stuck again at 49, so this must be a problem from the latest version of 6.4.

I attach the crash log here:

UPDATE: I managed from the TeamBlue 6.3 upgrade to 6.4 but this time I choose the 20210106 version, so the problem must be on somewhere in the latest versions.

Now I realized that using the 6.4 I have even less flash space available, so no good to put the rest of things I use normally.

Anyone knows or recommends a good image that doesn't take all the flash space?

Thanks.
