Strange. Ok, I will set selinux to engorcing in uboot config by default.
As long as we do not do this, access to some kernel resources (in permissive mode) will be denied by sepolicy…

However, these commands are no longer necessary. I've already sent you another bootloader.

Now install dtb as already described. Then install aml_upgrade_package.img.

No. Repeated unnecessarily.

1. Write aml_upgrade_package.img on the mSD card with Amlogic Burn Card Maker.

2. Copy _aml_dtb.PARTITION to the FAT partition of the mSD card and rename the * .ini file to * .ini.bak.

3. Start the TV Box from this mSD card and write the * .dtb.PARTITION on eMMC.

4. Remove the mSD card and rename the * .ini.bak to * .ini again.

5. Now start sd card upgrade.

P.S. In your case, the vendor uses the misc partition, which contains certain key signatures for certain applications. A manual installation of individual partitions does not help you, as the misc partition also has to be installed. Otherwise the stock fw will not run.

WiFi Bluetooth still not working

error system UI has stopped is flashing on screen again and again....

edit

In my observation, system UI stopped error comes when,

"system first time initialization of app" not come on android first boot..

Code

avc: denied { write } for pid=4700 comm="ndroid.systemui" name="property_service" dev="tmpfs" ino=8243 scontext=u:r:platform_app:s0:c512,c768 tcontext=u:object_r:property_socket:s0 tclass=sock_file permissive=0

Sys UI

Try to create a new rule for property_socket in sepolicy, allow write access to the sock_file:

Code

(allow platform_app property_socket (sock_file (open write)))

and recompile sepolicy..

WIFI

Code

[  111.636750@1] dhdsdio_download_code_file: Open firmware file failed /etc/wifi/4335/fw_bcm43455c0_ag.bin
[  111.649276@1] _dhdsdio_download_firmware: dongle image file download failed

Check that the /etc/wifi/4335/ directory contains the correct fw -> fw_bcm43455c0_ag.bin

Now Wifi is working, Thanks for guidance and Patience..

Bluetooth is still not turning on.., may be "Bluetooth: SCO socket layer failed" is the reason for it.

Check if BCM4345C0.hcd FW exists in bluetooth folder.

If necessary, you can download it here..

Try dropping BCM4345C0.hcd into /system/etc/bluetooth. I cannot read your log because of the different character encoding. Use UTF-8.

Hallo,

is there someone from "DACH" or nearby Europe who can bring my bricked device back to life?

I tried a firmware update. A logo or image appeared on the screen for a very short time. I couldn't see what it was. It was just a flash.

From then on the device was completely dead. And hasn't done anything since. I have read all the tips here. But that's technically too high for me. And I would like to have someone do it who understands something about it and has already done it.

ist hier jemand aus "DACH" oder dem nahen Europa, der mir mein gebricktes Gerät wieder zum Leben erwecken kann?

Ich hatte ein Firmwareupdate versucht. Es kam ganz kurz ein Logo oder Bildchen auf dem Bildschirm. Was es war, konnte ich nicht erkennen. Es war nur ein Aufblitzen.

Ab dann war das Gerät komplett tot. Und tut seitdem nichts mehr. Die ganzen Tipps hier habe ich zwar gelesen. Aber das ist mir technisch zu hoch. Und ich würde das gerne jemanden machen lassen, der davon was versteht und schon gemacht hat.
