BeadaPanel 5C stopped working. White flashing screen

Please copy these 2 files which are in FAT16 partition back to your local hard disk and then calculate their CRC checksums. Meanwhile calculate checksums for the files in same name on one drive. Compare those checksums and they should be identical.

Okay I downloaded the files and manually put the two zImage file and .dtb file in the parent directory for the FAT16 drive. Restarted PC and replugged USB, panel no longer flashing LED, no backlight still. It's as if the USB port does nothing at all when connected to the panel.

Previously when it was flashing the screen on and off with the blue LEDS it was showing the device as an unknown device in OTHER DEVICES in my device manager but it doesnt even show up there. Like I said, it's as if the USB is never even connected to the device no matter which USB I use.

I attached photos so it should be clear I confirmed it is the FAT16 drive I put those files in and plugging it in still does nothing when plugging in or show in device manager.

Yes I followed those procedures exactly, one at a time based on the starting point in your link. With the TF card inside the panel, the PC does not recognize the panel at all. I tried disconnected the TF card, and it showed up as an unknown device again which I attached as a screenshot(but blue light and screen do not turn on). I also tried reformatting the FAT16 partition and copied the 2 files from the OneDrive once more, still doesnt boot up.

I dont think the EXT4 partitions are corrupted, but just in case I formatted the primary EXT4 partition and restored the image file from the OneDrive onto the primary primary EXT4 partition. (I dont know if I'm supposed to do anything with the 2nd EXT4 partition labeled Unformatted(2) in disk genius) But that didn't do anything when connecting to BeadaPanel either. And I dont believe there is a partition overflow issue if there was before, checking partition table error shows no errors and I never saw any window popup about one since using DiskGenius on this issue a single time.

All that being done, still when TF card is plugged in, the device doesnt boot up. Maybe I am supposed to download a driver to the unknown device in my device manager that shows up when the TF card isnt connected before I connect the TF card for it to know how to boot or something? I'm at a loss at what the issue is.

The bootloader was corrupted on the TF card. This condition is very rare. We will prepare a recover TF image for your device in our lab ASAP. Again sorry for inconvenience of this issue.

Awesome, works great now! Loaded BeadaTools and set a picture and now I will leave it forever to display an image for aesthetics which is all I wanted for a while now. Thanks for fixing it!

I am glad to hear the device recover too.
