Toshiba 22BL712G - Potrzebny firmware w wersji V.0.6.8a

Mam dwa telewizory "ze śmietnika":

1. Pierwszy - uszkodzony zasilacz, wymienione diody, działa, firmware V.0.6.8a
2. Drugi - mrugająca dioda, ktoś już gmerał przy SPI Flash, jednak problem był w NAND. Znalezione w Elektrodzie firmware złapało, telewizor działa - wersja V.0.6.8c

Nie widzę jakichś większych różnic, poza zupełnie inna grafiką pierwszego poziomu menu:


V.0.6.8a


V.0.6.8c

Ze względów czysto estetycznych chciałbym w drugim odbiorniku zrobić downgrade do wersji a

Czy ktoś z Was dysponuje takim plikiem? Support Toshiby podaje tylko wersję c, a kontakt bezpośredni przez stronę się urywa:

If the motherboard is 17MB82S the latest software version is 1.3.7. It looks like 0.6.8a. It is installed with MENU 1505.

Вероятно мейн борд е 17MB62-2.6 автора на темата трябва да посочи?

Maybe it is 17MB62-2.6, I don't remember. TV is working and mounted on the wall. But I want Toshiba firmware only.

Is any method to dump firmware from TV to USB without desoldering NAND? Any service menu option?

Type MENU 4725 and see what the main is. If you don't find out, put a picture.

Why You need these informations? I need only V.0.6.8a firmware from Toshiba.

"Maybe it is 17MB62-2.6, I don't remember"
"Why You need these informations?'
Because I still haven't found out what the motherboard has the TV. You want a specific software and we don't even know what motherboard you have. In order not to take off the TV cover, the motherboard model can be found in the service menu. I gave you a software 1.3.7 which is the latest and looks like 0.6.8a. I give up.

The latest firmware from TOSHIBA is V.0.6.8c and I need only V.0.6.8a - nothing else. I want have the same version of firmware on both TVs. Any generic or 3rd party manufacturers (Blaupunkt, Medion etc.)

Download via USB mb62_hwprofile mb62_langprofile mb62_swprofile from the working MB and transfer to the other. The MB is old and I have no notes on how to do it.

I try this method and don't work on my TV:

Try saving from a working TV. Download via USB? Menu 1505

That's good idea. I tried MENU 4725, and here "USB Operations" does nothing.

Insert these three folders on the USB memory, it goes on as with MB82.
RECOMMENDATION: Save old files!
Włóż te trzy foldery do pamięci USB, to działa jak z MB82.
ZALECENIE: Zapisz stare pliki!
DownloadPq.mb62
DownloadProfile.mb62
DownloadSpi.mb62

At your own risk!

Sorry, that going to: "Do You want to upgrade the software"? Any option to dump actual firmware to USB.

Coś chyba źle go zrozumiałeś. Trzeba utworzyć trzy pliki a nie foldery o wskazanych nazwach. Po wejściu w menu serwisowe i wybraniu operacje USB zostanie zapisany profil TV na USB.

Thanks!
Now, I have some files, that I can't copy to computer's disk. What can I do with this drive on second (target) TV?

Te pliki są niezbędne jak wgrasz oprogramowanie V.0.6.8a od innego producenta który stosuje ten sam model płyty. Pozwala ustawić odpowiednią konfiguracje sprzętowa, programową itp. Nie wiem jak rozwiązać problem z szatą graficzną .
Najprościej skopiować zawartość NAND przy użyciu programatora.

What can I do with this drive on second (target) TV?

Post the 3 folders in the topic to rework.

These 3 folders are empty. But, files are protected? I can't copy them to computer's disk.

From the working TV:Insert the file into a formatted flash drive.
Perform the operation from 12 post.

1. New files has the same problem - can't copy to computer's disk
2. If I plug USB drive to second TV, [menu], 1505 - I get "Software update failed"

So...
1. Clear USB Flash drive, low capacity, formatted as FAT
2. File "DownloadPq.mb62t" on the clear USB drive
3. 1st TV (with software V.0.6.8a) - plug USB drive in
4. [MENU] > 4725 > USB Operations (doing something)
5. 2nd TV (with software V.0.6.8b) - plug USB drive in
6. [MENU] > 4725 > USB Operations (doing something)
7. Reebot 2nd TV > none effect Still "new", colorless menu.

The procedure has been discussed several times!
This is the last and I will no write more in this topic!
DownloadPq.mb62t 1. Clear USB Flash drive, low capacity, formatted as FAT Insert the specified file
[MENU] > 4725 > USB Operations

Exactly. That method doesn't work on my TVs.

Dodano po 13 [minuty]:

I tried some different USB drives (from 256MB to 512MB) and on 2nd TV is still colorless menu layout.
