won,t boot from sd card

  • I have a tonbux t11, which I have flashed usb to usb with a 905x firmware it says the box is a m9cmax box and it works but the internet is shocking, only want kodi so I thought i would try libre but the s905x logo comes on and it goes to recovery but does not boot to libre. The box would not boot from sd card before when i tried a android rom, it did however flash through amolic burning tool usb to usb through pc. Is can i use the usb amolic burning tool to put libre on box, this i know would take android off but can it be done. If anyone knows if this box can be booted from sd can they tell me? I would like to dual boot really , it dosn't have the option to boot to recovery in the reset options. Also the image i have has one type of dtb file and i know how to alter this trying sd method but if the amolic burn works it uses an image file how do I get the right image file with my dtb i need?

    The box worked well for a while watching plenty of stuff on kodi then it wouldn't play anything, reinstalled everything and it worked well again and then stopped again when the browser was opened it took ages for page to load even though signal was good, though i would try a firmware flash as the original had happyplay and happy cast running in background even though I never used it and couldn't find it then couldn't delete it, when the new flash worked i thought i was in buisness again the internet was so slow it was unusable, the first few times of browser page loading isn't to bad then it times out, maybe the wifi is shot but sometimes it worked for a few weeks then didn't again. I was going to try libre to see if that worked but I belive this box is blocked from booting from sd somehow, These are the details of the box .. chipset ar94 2ghz...cpu octo-core mali 450....2 gb ddr3 8gb flash amolic chip s905x board says g9cx_2_vo.95 on sticker and g9sx_vo.96 2016/11/23 printed on board on back of board there is a chip with grp47Dgshd on it .... installed amologic s905x image on it and now it says it is a m9cmax box..

    Any help appreciated

    Do some boxes just not boot from sd?

    can i burn image usb to usb on pc ?

    can anyone tell me which dtb I would need for this box and how i would manipulate this onto my image?

    thanks
