Blank Screen
Reimund-Koenig opened this issue · 6 comments
Hi @pvvx, first of all: Thank you for your work.
My Display is blank since I flashed "/atc1441/ATC_MiThermometer" latest release to my brand new LYWSD03MMC (2019DP8115) device. Connecting, flashing OTA is working. Advertising and display not.
Flashed back "original FW" and your latest custom FW (ATC_Thermometer32z.bin). Display stayed blank.
Also tried "Repair LCD" button with your latest FW which returns "7:06:02 AM: Send 'Repair LCD' ok" but display stayed blank.
Still connecting, flashing OTA is working. Advertising and display are broken.
Is there a way to recover the display and advertising?
(Is there more hope for recovery if I flash via com-adapter?)
Cheers
Reimund

Still have a blank display without any reaction :(
I was brave and flashed a second device OTA.
Same issue > Display is blank :-(
Seems like they did some changes to prevent flashing custom Firmwares under the same CMITID (2019DP8115) and name (LYWSD03MMC).
Are you able to dump the firmware of a stock one?

Is this possible OTA? I still have some new ones with stock firmware.
Maybe @Reimund-Koenig can help if adapter is needed:
