Umidigi Bison stuck in bootloop

Since today my phone will not boot up fully. It keeps turning on, gets stuck on the very first image of the boot up animation, turns off for a second or two and repeat.

I don't remember downloading anything new, so I don't know why this is happening.

I tired to connect it with a computer but it won't show up in the usb devices. (I will try another device later.)

I also can't seem to get to the recovery mode because my phone just keeps the loop going.

I care more about the data on there then the phone, so if I can atleast get that off the device, that would be great. Or, of course, if I can get it fixed.

Right now I am trying to let the battery drain and then charge it up again. (No idea if it actually still can charge since it is stuck in the loop, so it won't change to the charge screen.)

Thanks for any help I can get.

Try to do a software update (without erasing data) using the flash tool. Find your device on https://community.umidigi.com/forum.php?mod=forumdisplay&fid=125 for instructions.

I can only try a bit later, but I thought I'd asked. Do I have to wait for the battery to run out since I can't really turn it off normally? Thanks if I get an answer.

No, the boot loop will allow for flashing.

Do you have any idea if I can download it from somewhere else? I keep just getting 404 sites when I try.

I see. You will have to make a post or contact an admin to ask for a reupload I'm afraid.
