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.

Free, abundant OTA television separates this country from many others. ATSC1 has only been in force since 2009. The wireless industry has enough spectrum. Enough of 'planned obsolesce'.

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


Cable-free since Nov 2013

fyi: current shipping model of SunKey sk-903h is still buggy v4 version, but the Lutema Air v6 firmware corrects the things I care about. Happy with the resulting Franken-box.

If you look on the motherboard, right next to the flash 8-pin SPI chip are 4 pins that don't have header--that is a serial port. The TX line is number 4 and the RX line is pin3. Use 115.2kbaud 8,N,1 settings and expect to see a lot of output on box boot-up. One line in the output should say "hit any key to stop boot"--if you do get to it in time you will drop into a monitor program and you get more commands if you hit ? or help. On a MStar box I have that is for satellite DVB-S2 signals I see the following in response to help:

<< MStar >>#


-------------------------------------------------------------
BTW I disassembled the above usb file and the structure is very similar to my satellite box's code. They have a common register for serial transmit: 0xBF201300


The logo is jpg and is easy to extract and view--in the usb file look around 0x70000 it is 0xb054 bytes in size.


The main sw is lzma compressed and there is a tool that is in the 7-zip SDK that can un-pack it.
The boot is in two parts--the first is bfc00000 and executes in flash, the second is moved to RAM for execution at 0x81000000 0x9150 bytes are moved starting at bfc02df0.

Well the combination of serial port commands, the usb start and fatwrite commands make for the easiest dump of the flash contents that I've seen since jtagging ports were not in boxes. fatwrite usb 0 0xbfc00000 fw.bin 0x400000 will give you a file named fw.bin that has the 4Meg flash contents in the usb in root directory.

The power supply went bad on my iKonvert SC-58

Mine would not work any more. I hacked another 5 volt power supply on it and that make it worked. So I open up the power supply that came with it by hammering it open.

A capacitor in the power supply was puffed up and the outside coding ripped apart.

I unsolder it. A 10 volt 1500 U. I looked and had a 10 volt 2000 U. Solder it in and it works. That new capacitor is taller and would not fit in the case. I just made a hole in the case for the capacitor to stick out of it.

So it's fixed. I wanted to post about it if any one else has this happen to them that it my be a bad capacitor in the power supply.

Remote for Proscan PAT-102

Has anyone had success with finding remote codes for the Proscan version of this series of Box? I have a logitech harmony remote and when I search in the Harmony database it only seems to what to pick the PAT-102B and not the PAT-102 box. I lost the remote and was hoping to just use the harmony but have been unsuccessful in getting the harmony to function with the Proscan box.

Anybody have the PAT-102 that has the ability to program the remote codes into the harmony database?

I have tried all the like boxes as options in the harmony database and none seem to be working with the Proscan PAT-102.

Pointers?

Thank you
