thanls for replying.
I'm not using a cutom DA or mtk bypass.Why I can only readback preloader?Did that mean that the device has secure boot?
The device was bought from my school with custom android.It closed adb and any other usb debug and locked bootloader which I cant unlock.It also does not allow to install any apks without permissionI'm graduated now and no longer use the tablet.I just want to exact the full rom and root it inorder to turn it into a normal Android device.However,I Can't get any information about the deviceon Google.
cpu is mt6761
Thanks again

By rec.img, do you mean recovery.img? What addresses did you use to dump these?

if you're able to backup preloader without a custom da or mtk bypass then the device doesn't have secure boot
try to disconnect / reconnect the battery then attempt to backup the firmware again

I successfully read back boot.img and recovery.img,after patched with Magisk, I flashed boot.img back,but it has avb and I can’t boot my device. I don’t know how to disable that on my device since it has an unlock bootloader.There was no one unlock options in settings,it seems that it was deleted by developer.However,without unlock bootloader,I can’t flash vbmeta.img. I used spflashtool to flash vbmeta,it doesn’t work. I really don’t know how can I do now.Please help.Thanks
