Desay 187A brick fix via USB to TTL

Desay 187A RCD330 plus, because of its outstanding functions and playability, is liked by many friends. Its operating system is Win CE 6.0, and you can access its desktop system by upgrading firmware. Like other windows operating systems, you can install software and copy, paste and delete files under Windows interface.

Sorry, only logged-in users can see spoilers.

Some friends have made some mistakes in the process of upgrading or deleted system files, some of them are human-made, some of them are caused by unstable storage devices. The head unit becomes a brick.

There are two main situations,
1. The system stops at the public boot logo interface and restarts at a fixed time interval;
2. The system prompts that upgrading is in progress, the scroll bar stops for a long time, and there is no other response.

You can connect to the main board of Desay 187A through USB to TTL, use putty software to enter its underlying system, and fix it.

 

Run the putty software, set the correct COM port and rate (115200). The port of COM port can be viewed through the device manager.

When the head unit is turned on, the window on the computer points to putty, and keeps pressing the space bar,
It will enter the boot menu.
