change another USB line, I finally do it.

Solved: SP Flash Tool error at md1img / STATUS_DOWNLOAD_EXCEPTION (0xC0050003)

My device had a flashing error during "downloading md1img" in SP Flash Tool, with:
STATUS_DOWNLOAD_EXCEPTION (0xC0050003)

In my case, the problem was NOT the ROM package or the flashing tool itself.
The real cause was the USB cable.

Fix:
- I replaced the USB cable with another proper data cable
- Then flashing worked normally

So if anyone gets stuck at md1img with 0xC0050003, please try:
1. Change to another USB data cable
2. Use a direct USB port on the computer
3. Avoid low-quality or charge-only cables

This solved the problem for me.

Nice guide on using SP Flash Tool, especially for beginners dealing with firmware issues. One thing I’ve noticed is that after flashing or fixing devices, having quick access to tools for testing or calculations really helps. I sometimes use this browser based TI-84 simulator to check values or graphs without installing anything, which saves time during troubleshooting.
