[Question]DMG19108C156_05WTC T5L2 Basic firmware trough PGT05 after black screen

igorK

Hello. After some error in config file I had a black screen and a panel doesn't upload files from sd card. I have PGT05 programmer. Post please files to download basic firmware and factory project to check that display works. А board on the display has 3 7-pins groups of holes for PGT (at photo): T5L_DGUS, T5L_LCD1, T5L_LCD2. Which group I have to use to connect PGT? Write please required names of firmware files to transfer from sd to pgt.

Pls kindly see the attached PGT05 files for DMG19108C156_05WTC for your use.

Thank you. Yesterday I loaded some firmwares in T5L_LCD1 and T5L_LCD2 connectors, the same as in T5L_DGUS, so my coprocessor kernels are wrong too. Are coprocessor kernels same as gui kernel in attached files? If no, post them please.

Hello! The coprocessor kernel sent to you upstairs is the one used for your screen.

Hello. Sorry for the possibly stupid question, but I don't fully understand. I tried to upload attached kernel, but it didn't help me. A backlight turns on, but uploading process from sd card with blue screen doesn't start. In attached files there is one erase file and one kernel. As I understand this is gui kernel that must be uploaded trough T5L_DGUS connector. There are also 2 connectors (T5_LCD1, T5L_LCD2), through which as I understand may be uploaded coprocessors kernels. Could you post this kernels if they exist? Couple days ago I uploaded trough this jumpers some kernels from internet, I suppose that they are wrong, so I need suitable kernels for T5_LCD1, T5L_LCD2.From instruction:
Generally, problems caused by SD card burning the wrong kernel can be recovered by updating the burning GUI kernel.
If it is necessary to update the coprocessor kernel, the method is the same, except for updating the coprocessor kernel
and burning the corresponding kernel to the hole T5L_LCD of the screen. If there are two coprocessor chips, repeat
the same steps twice, and the cores of the three holes are burned in no particular order.

Can't it be restored to normal with the above file? The screenshot above is the kernel file

In this type of display with T5L2 there are 3 connectors, as I understand each has their own basic firmware. At screenshot there is a ui kernel to upload trough T5L_DGUS connector. But there also must be kernels for coprocessors or not?

The attachment is the kernel used by the coprocessor.

Thank you! After loading your firmware into the t5l_lcd connectors and the Serena firmware into the t5l_dgus connector, the panel began loading programs from the flash drive and working.
