Warm greetings to all forum members. Now, regarding the topic: I have a Lobod TV that was stuck on the logo screen; after an update attempt that failed, it is now stuck in standby mode. I would like to ask colleagues if anyone has tested eMMC content (compatible with the RT809H programmer) for the CV338H-T42 board (4GB RAM) and could post it on the forum. I am also attaching some photos. Thank you in advance.

ممكن تجربة أية شحنة cv338 و بعدها تمرير الفيرموار
أظن أنك مرر فيرموار cv358 بدل cv338 .. هذا الخطأ حدث معي أكثر من مرة

Hello, Mr. Elkhajati. Let me clarify the situation: initially, the TV was stuck on the logo. I tried a recovery process but it was unsuccessful. Then, I found the original USB firmware for this TV; the update started and reached about 36% (near the halfway point) when the TV suddenly shut down. When I turned it back on, the TV started up but without an image, and it would no longer accept the firmware from the USB. I tried using UART, but the port was locked, so the only remaining option is an eMMC dump. I am looking for a tested eMMC dump—one that has been read and written using an RT809H programmer. As I mentioned earlier, the board is a CV338H-T42 with 4GB eMMC. I have tried dumps found online, but they didn't work; currently, the board is stuck in standby mode. Thank you for your help.

try this one

I'll try it tomorrow.
Thanks for the effort.

Hi. It is not suitable for my case.

Here you go, brother Fadili, the shipment is 4GB in size. Good luck.
The extension must be changed so that the RT809H programmer can recognize it.

First of all, thank you for the help. The TV was fixed by modifying the EXT_CSD file using HxD: I changed the value at row `000000B0`, column `03`—which was originally `00`—to `08`, `38`, or `48`. Then, the original firmware was loaded via the USB port, and the TV returned to normal working order. If anyone needs the eMMC or USB firmware for this type of board, I can send it without any problem.
