Update software DVD player based on chip MT13x9 (MediaTek)
Video developed by leaps and bounds.
Not so long ago the consumer was happy appearance
Sales of relatively cheap players
Disc format DVD, VCD, Audio CD, MP3.
But less than a year, and appeared on the market player and
home theater systems, capable of reproducing
not only drives these formats, but also drives the format MPEG4. To date, a large
the number of players that are sold on
the CIS, are collected based on chips MEDIATEK -
MT1379 and MT 1389.
Thanks to modern technology
innovations have appeared servisnikov
opportunity not only to update the
software, but also to repair vehicles,
malfunctioning because of the failure of software
provide, directly connected to the
decoder board MT13h9.
There are situations when, after a poor update or failure
stops working - no response by pressing
control buttons, does not "see the disc, on screen
indication does not properly display the characters and
etc. How can that be, in such cases? As
restore such a device? For this
need homemade data cable, PC
and above, the program MTKTOOL.
The first step is to gather data cable on a chip MAH232.[ندعوك للتسجيل في المنتدى أو التعريف بنفسك لمعاينة هذه الصورة]
Figure 1. Scheme of the data cable.
D1, D2 - Diodes 1N4148; D3, D4 - zener voltage to 2.7 V.;
C1, C2 - capacitors - 100 nF C3 - C6 - 1mkF x 25V;
R1 - Resistor 1 kOhm, 0.25 W power;
US 1 - chip level converter MAH232;
IC 1 - chip voltage regulator 78L05. [ندعوك للتسجيل في المنتدى أو التعريف بنفسك لمعاينة هذه الصورة]

After assembling the circuit operates without any adjustment. For
stable operation is very important in settings
program correctly assign the COM - port and
Acceptance rate of data transmission.
Immediately say, that you can apply
data cable from a mobile phone, such as SIEMENS
C35, but in this case
correctly identify the findings TXD, RXD, GND.[ندعوك للتسجيل في المنتدى أو التعريف بنفسك لمعاينة هذه الصورة]

If you do not have a working firmware, it can be
download with a similar device, but obviously
worker. To do this: connect the data cable to
COM port on your computer with one hand and the other to
jack / V33/TXD/RXD/GND / on-board DVD

Run the program MTKTOOl, (Figure 6.) Choose the program settings of a COM port[ندعوك للتسجيل في المنتدى أو التعريف بنفسك لمعاينة هذه الصورة]
Figure 6. The program window MTKTOOl
and turn on DVD player.
Push the button "BACKUP" in the window.
The first thing that should happen - the program must
determine the type of flash memory chips. File with
backup.bin name is stored in the folder where the
program itself. When a load indicator
be - 100%, this means that the process of reading
information from the flash memory has been successfully completed.
Connect the data cable connector to be switched off
not working player, pointing to the window
program path to our downloaded file backup.bin.
Turn on the machine, click in a box
click "UPGRADE". Again - the first thing that must be
happen is the program should determine the type.
The process has started. Download progress bar is filled with
blue stripe up - 100%.
Turn off the DVD player,
disconnect the connector from the motherboard and turned on again.
The upgrade process is completed. (Fig. [ندعوك للتسجيل في المنتدى أو التعريف بنفسك لمعاينة هذه الصورة]
Figure 8. The upgrade process is completedFor lovers of experiment
This site (sm.ssylku), there are other
interesting programs, one of them MTKReMarker. This
The program allows you to make changes in
firmware from the remapping on the panel
management system and to replace the "LOGO"
that appears when you turn on the machine. If
you have friends and colleagues have cravings for experimentation,
Do not forget, before pouring
Modified firmware to make backup.
Such download a working firmware can also be written
on a CD and use it in
if the machine reads the discs, but it
is not a valid indication, the panel does not work
management, etc.How to create a disc with the firmware?
To write the firmware on a CD, you must have a CD recorder and software NERO, for
with CD recorders.
Run the program NERO, create a data disk,
drag in the window file backup.bin, rename it to a file called MTK.BIN and produce burn the disc.Important! On the drive there should be no other information, and to do better to cancel the multisession.Attention! All that is described here relate to the DVD-based chips MEDIATEK -
MT1379 & MT1389 (MPG4). During the "dead" machines, I am not responsible, be attentive to what you're doing.
