Another way to recover your box

[ldrrp]

I got my device into a bootloop with a specific rom and i was stuck because the update button would no longer work on this firmware. I was unable to use the emmc maskrom mode pins as they were not accessible and i couldn't find any other way into the box until now.

Using a usb to ttl serial cable and putty on 115200 speed i was able to access the terminal on boot by mashing the enter key as it boots. After u get a terminal type "update" and our all set, you can now flash with the usb to usb cable from your computer.

It would be nice if you stated how exactly you communicated with the box using your usb to ttl serial cable.
- For example did you use the AV port ? (as using such a port or sound port I was able to communicate with some Samsung TVs).
- Or you just opened the box and found the RX,TX leads? In such a case it would be nice to give us at least a photo of the board and the exact position where you connected your serial cable.

Hey, i did end up making a tutorial. https://silocitylabs.com/post/2020/0...xes-everytime/

I also found a device that lets u get access to serial from the micro sd card slot withouth opening the device. I cant seem to find out where to buy one. Look at Method 6 in the link
