New thread for support of SK-903H based boxes.


There is a new firmware V6 that replaces the V4 from the factory.


Corrects the original factory V4 firmware bugs that add 5 days to a daily and weekly timer event,
Adds the Daylight Savings Time option,
Allows use with computer formatted NTFS discs.

But EPG only shows info for current and next program

Contains the logo for the Lutema AirTV but also works with the more common Axess CB-3001, I have tested it on that box.
After upgrade remote control, front panel light and buttons function properly.



Most likely also works with the Supersonic ikonvert SC-57 box, but I cannot personally verify this so if you own a SC-57 please post your system info screen here first for comparison with HW version.

Axess CB-3001 V4 factory firmware system info



Lutema AirTV V4 factory firmware system info



V6 firmware upgrade system info



Notice both factory firmware screens state

model sk-903 v1.1
hw version AC_3721_V1.0

sw versions
50USAATBV04 ATV = airTV
50USAAXSV04 AXS = Axess

Only difference I could find is the boot screen logos




AirTV board


Axess CB-3001 board



Notice the same build on both boards
SK-903 V2.0
AC_3722 V1.0



This box uses the MSTAR MSD7816 chip like the Iview 3500stb, Home HW150PVR, Ematic at103b, ViewTV AT-163, Proscan PAT-102, QFX CV-100, Stellar Labs DT-1200, Stellar Labs DT-800, Naxa NT-52, Supersonic ikonvert SC-56 and SC-58. But there are many hardware and software differences to consider. Only the new version of the Iview 3500stbii with the ch 3/4 switch uses the same msb1237 demodulator chip so the original iview and homeworx firmwares are not compatible with the sunkey boxes because they used a samsung S5H1411 demod chip.

front and back of remote control for CB-3001 and AirTV same remote board also used for NT-52, DT-1200


remote key pad next to SL DT-1200 remote which uses same remote board but different keypad.



This same style remote is used for the ematic at103b but the remote board is programmed differently and thus only about 2/3 of the keys are identical.


The best feature of this box is that you can operate the Axess CB-3001 in the same environment as the Iview 3500stbii and the Homeworx HW150PVR since the three remotes operate on independent and non conflicting remote codes. Of course if this is your objection you could also go with the Ematic AT103B which comes with corrected firmware right out of the box.



Instructions to use file


Proceed to menu > system > Restore Factory Default password 888888

Copy the "usb_upgrade_all_flash.bin” to a FAT32 formatted drive.
Insert drive to converter box
Proceed to menu > system > software udate
Select “usb_upgrade_all_flash.bin”
Wait for update to proceed to blue screen and 100% complete message.
Do Not power off during this time.
Receiver will reboot once update is completed

Proceed to menu > system > Restore Factory Default password 888888



V06 corrects the following

Daily and weekly recordings bugs
Midnight recording bug
Daylight Saving time option
NTFS pre-formatted drive now accepted for recording


Update will change the boot up screen to airtv

Caution EPG is not working properly in V6 .


There appears to be some bug in the V6 EPG which does not work for the full 7 days like it did in V4. Now it only shows 1 hr worth of info and displays the correct time/date but the wrong date for the info subtracting 5 days.

Abundant OTA television is what makes this country different from all others. Lets keep it this way.
The Internet is no place for streaming video.

Hmmm,  those screens look awfully familiar.

 

Are these boxes yet more clones like the iView and Homeworx boxes?

 

Edit: Yes, I see now that they are
