hello,
I need support - I have S812 and I tried to follow these steps, where problem occurs in step n.8 - instead of "boot from external media" after second restart, it booted from original ROM immediately.
There is no black screen for 7-10minutes, it just boot as usual. I also tried the step n.9 (swith dtb.img), but problem remains the same. I followed all the steps from this guide.
Can you suggest possible mistakes, which I could made please ?
I would take any suggestion.
1. Download the desired image
2. Unpack
3. Record an image on the medium
4. to run Android
5. open the app "Update&Backup"
6. Select local update and an archive on removable media (aml_update.zip)
7. Run update
8. System twice to reboot and start running the system from external media.
9. If after 7-10 minutes on the monitor not to receive any messages on system startup. Turn off TV box and add in manual in the first partition (FAT) the file "dtb.img". On the media there is a directory dtb from where you can take the files and copy them to the root of the renaming of "dtb.img".
Need to pick up the option for the file system will run. Pay attention, after you add\change the dtb file, you need to try to run the system and waiting to run 7-10 minutes. If not happened, repeat with a different dtb file.
