Ender 3 Pro Bricked After Update (board 4.2.2)
After performing the update with the file "4.2.2 Ender-3 pro 32bit Marlin2.0.1 BLtouch V1.3.1with adapter board.rar", the printer no longer displays any information on the LCD, leaving only the blue screen.
I've tried to put previous updates, rename the .bin file, memory cards with different size and format types, but nothing works to recover the printer.
Is there a recovery process?
I managed to recover my printer using an 8gb memory card formatted in FAT32 and placing only this file.
I hope to help others and thank you for the help provided.
After brushing back the original firmware, test the boot up again, if there is no problem, then brush BLTOUCH firmware (the firmware must correspond to the motherboard version and whether BLTOUCH has an adapter board installed) https://www.creality.com/download

Guys I’m in the same boat?? Worked great until I went to upgrade the software, now nothing works
@esoares Same problem here on an ender 3 v2.... 4.2.2 board as well, lcd screen is lit.... @admin, some help would be appreciated. Can we somehow confirm the bootloader is still ok ? Can you provide the bin for the bootloader, and can it be reflashed using stlink ?
I just tested all the firmware for the 4.2.2 board available on the website one by one and also compiled the TH3D firmware but none worked.
The printer does not give any sign of life, the LCD only remains lit.
