Failed display firmware update

[MochiTek]

Hello!

https://github.com/mriscoc/Ender3V2S1/wiki/How-to-update-the-display

I tried updating the display firmware as per the link, now no icons or text appear. So far I have tried to reinstall firmware on the printer but still the same issue persist.

The firmware on the printer seems to be ok but the display is basically unusable now. All was working before with no issues. All i wanted to do was to get the new icons and colours working.

Note i have re flashed with the MM firmware in my attempt to fix. I didn't want to risk my nozel bashing into my print plate without resetting my z-offset as i cant see the options in the menu.

My Printer:
Mobo: 4.2.7 with CR touch
Firmware: Ender3V2-427-MM-MPC-20231217.bin
Display: DWIN display (i cant see any markings of the model number but is identical to the DWIN image)

Steps done:

• SD (8GB) card formatted with a 4 KB sector size

• Downloaded the Giadej boot image and icons compilation DWIN_SET and loaded it on SD Card (this caused the issue)

• Tried installing the stock display but the screen quickly flashes BLUE then RED and remains red. (Does not appear to want to flash)

  I noticed this is only the T5UIC1_V20_4页面_191022.BIN in this DWIN_SET folder. Is this expected?

Any help or guidance you can provide would be greatly appreciated!

UPDATE

Issue resolved. Turns out i had a bad SD card.
Bought a new one and display firmware flashed with no issues... what a relief.

Wanting to post an update to help others who may face the same issue.

Happy printing :)
