Rep: (31)
* alegord78 , then how this image pour into the scaler?



Rep: (320)
* Crazy_cooler
Well ... disassemble your firmware, replace the image, assemble and flash it on health.



Rep: (31)
* pashkovv78 , when unpacking what? There is a backup section and a flash drive dump.

Posted on 10/15/2017, 17:44:

* alegord78 , the fact of the matter is that our firmware has not yet been found (mine at least). If only on the firmware that acura2 was trying to try.



Rep: (31)
* acura2 I asked you why for the firmware. Do you remember that you could not return to your backup and had to flash another firmware (which is yours now), so you can ride with that bootloader as mine (judging by the production date) maybe if you flash it, can you restore the backup?



Rep: (320)
* Crazy_cooler
Well so ... you have to try something. I feel a long song ... which firmware should I drop?

Rep: (31)
* alegord78 , let's take the acura2 firmware, you have it, in my opinion, and I dropped out of testing for 2 weeks for sure. (on the matrix 2 lamps died, I ordered LEDs today, I will wait)



Rep: (320)
* Crazy_cooler
Well, you give ... I reassemble every day on the firmware, where your ... hell knows ... GIVE a LINK !!!)) It is necessary to adjust from different branches. It turns out on Mstar so much technology "hanging."

Rep: (31)
* alegord78 , Universal scaler MSD338STV5.0 [Android] (Post acura2 # 65996734) Here you can take under the resolution of 1440 * 900 as far as I remember from acura2 is exactly that.



Rep: (320)
* Crazy_cooler
OK



Rep: (23)
* Crazy_cooler I tried to recover from backup on the Chinese firmware from the cap. Nothing happened on the screen saver. I look at your backup in size, it seems to be smaller than mine, and later I will try to recover from yours. The Chinese firmware seems completely different, there even the settings menu is divided into separate windows. Maybe even try. BBK-ovsky firmware peres renamed messi.bin. Only I am afraid then I can not flash my firmware. May not catch. There would be an opportunity to dump a flash on the entrails. One would not be afraid.



Rep: (144)
* Crazy_cooler ,
There is also a folder with two firmware.



Rep: (23)
* alegord78, I tried to replace all the folders of the TV through the es file manager, in the middle of the replacement, the TV turned off. And more on the remote did not respond. When turned on, the button hangs on the screen saver.



Rep: (31)
* acura2 I do not know, I think I need an analysis here, and an understanding of what is responsible for what ... And it’s hardly possible to rewrite blindly. Give someone a thread folder tvconfig from bbk and I sit with my compare ...

Part of the elements is not soldered on the board itself.

Judging by the photo, there is a jumper in the DTMB position. It would be nice to rewire it to DVB position.



Rep: (320)
* Crazy_cooler
Try

Resolution corrected to 1440x900.



Rep: (31)
* alegord78 , thank! We are waiting for the result of our acura2 tester, so far I have no matrix (((



Rep: (320)
* Crazy_cooler
As I wrote earlier, your firmware is not standard ... the build script does not take. Half manual assembly. Yes, I need a check ... And here it’s not clear to me .. will it work or not. The result is not predictable. It turned out compote of BBK and scaler.
