Before you write the new u-boot.bin into the emmc, you have to test it to avoid the boot loop
1. Burn the new u-boot.bin.sd.bin onto the mSD card and insert it into the TV box
2. Run init 3 and reset
3. Check whether the new uboot is functional
4. If everything is OK, write the new uboot.bin on emmc

Dear Sir

Stock DTB file attached as required

Quarry/Question : I don't understand why my box does not support stock firmware..

and giving boot loop after install. may be i am not getting right firmware file, but i have tried almost all the files available online.

You need to replace 4 files:

bootloader.PARTITION = u-boot.bin

aml_sdc_burn.UBOOT = u-boot.bin.sd.bin

u-boot.bin.usb.bl2 = DDR.USB

u-boot.bin.usb.tpl = UBOOT.USB

today i tried USB burning method

Replace all 04 files, (stock image used, provided by you previously)

and packed the image and burned through USB,

Device booted after reset, but it was giving error "system UI has stopped" after booting

then in same image repacked with replacing only 02 nos files only uboot and uboot sd

and after usb burning, device booted, but wifi and bluetooth not working in this image

uart log of successful boot is attached...

I only see problems in the incompatibility of Sepolicy rules..

Try to put the SELinux into Enforce mode.

Abort autoboot and change the mode:

Code

setenv EnableSelinux enforcing
saveenv
reset

In UART after typing below cmd and when pressed enter

setenv EnableSelinux enforcing

it seems nothing happened (log was blank, after it)

then entered

saveenv

reset

But wifi does not work

UART does not works when HDMI connected,

How to get wifi not working log, so that you can see it for diagnose.
