How to restore a tuner after unsuccessful firmware. U2C resuscitation and recovery
18.11.2009, 13:21
Greetings everyone!!! Guys, someone help. Something happened to my SKYON DSR2300 tuner. I turn it on and the display says boot. I understand that sigh is the processor. please tell me how to revive the tuner. I try to flash it somehow through the skyonlink-4.0 program, click on setup comm, and in response I see a connection error, and there is no more shift. Tell me what should I do? I will be very grateful to you.

The firmware has crashed, you need to restore the bootloader. Here are all the programs and software for recovery + the latest software 5.46.
I took the program for filling and software. I tried to flash it, nothing changed. I launch the bootloader, select the software and also select the port. and I click on record, it says connection and that’s it. On the tuner display, as it was written boot, it remains the same. I checked the port, connected another globo tuner, and there it sees the port, starts writing, and then it’s muffled, like in a tank. What else could you recommend to restore the tuner, please help with advice.

I can’t run the skyonlink-4.0 program, I click on setup comm, and in response it gives a connection error, and the display only says boot and that’s it
Tell. Where on the board is the place for connecting Jtag, I can’t find the inscription rst cnd tdo, etc. Usually the board shows the place for Jtag, but I can’t find it on this tuner.

Irakliy, if the receiver has already been disassembled, then check the supply voltage, maybe we’re muddying the waters in vain?
The voltage on the power supply and the output correspond to the diagram. I checked this at the very beginning. The child just admitted that he ate the flash. and downloaded some other software. I took the openbox software. and went out to the queen.

Irakli, I didn’t restore Jtag myself, but I modified this receiver, here’s some info to make it clearer. The Jtag connector is a standard 20-pin.
Jtag pin number. Pin name. Processor leg. Resistor. LPT pin number.
19 - TRST - 109 /5518/ - 100 R - 5
15 - TDO - 111 /5518/ - 33 R - 13
13 - TDI - 112 /5518/ - 100 R - 4
11 - TCK - 113 /5518/ - 100 R - 3
9 - TMS - 110 /5518/ - 100 R - 2
Jtag I have 74NS244 on the chip. This revived the globo-like ones. Now I will look for the legs on the processor. The board has a connector for 20 legs, it is marked A5, but the leg report is not indicated. I took and rewired the pins on the processor, I took pin 109 of the processor, but I couldn’t find pin 19 on the connector, I rang the tester but I couldn’t find the circuit. Maybe I lost count on the processor. Thank you very much for helping me. I'll try it now.

Irakli Well, I figured it out, there are no photos of what goes where or I could describe it in more detail.
25.11.2009, 20:46
There is an idea for Skyon-2300 users who watch Digi TV. We upload firmware 5.46 to the receiver, reset the emulator to factory settings. We turn on the emulator again and remove the dump with Jtag. Post it on the forum, I’ll try to disable the AU on Digi TV. We upload the edited dump to the res with the same Jtag. Rainbow and plus balls and Digi TV work. Who will take the risk?

Hello. Tell me SKYON2300 no signal upper scale 1/3, middle max., lower zero?
You write on which satellite and transponder or which channel.
04.03.2010, 19:18
yurec, Open 300 - 820 have similar problems. Check the connections on the I2C bus between the processor and the tuner. Skyon didn’t understand it, but in the Opens there are 8 pins. tuner - 194 pins percent, 9 pin. tuner - 195 pin. percent Connected through resistances 22 Ohm x 2 pcs., a total of 44 Ohms.
04.03.2010, 20:55
Thanks for the answer. I checked the connections, everything is fine, the problem remains. Any other ideas?
04.03.2010, 21:03
The problem is in the tuner, all connections between the processor and the tuner are ringing. What tuner is installed in the Skyone?
Quote from another forum: If there is a problem with a square bus, the signal/noise scale is full, it is unlikely that it is. Check the 3.3V power supply of the SHARP input block, if it is normal, then try changing it.
They suggest replacing the entrance block.
04.03.2010, 21:27
The problem is not with the tuner, that's for sure. I removed the tuner, the same thing appears on the screen. Maybe the flash drive is glitching?
04.03.2010, 21:30
Only in the tuner, flash has nothing to do with it.
05.03.2010, 03:00
Skyon didn't understand
DSR-2300
05.03.2010, 17:22
I found it on one forum:(... I came across two versions of this tuner with different HF blocks. But when loading a flash drive from the wrong “assembly”, the tuner does not see the signal at all, the same thing happens when dubbing from tuner to tuner with different HF blocks. ..). If so, where can I get the required dump?
05.03.2010, 17:37
yurec, what kind of tuner does yours have? Well, download the dump from Skyon, which is on our forum, if it’s the wrong one, knock on Bashir’s door, maybe he can tell you something. But I still don’t understand why it stopped showing res?

As I was told, when they brought the tuner, there was a power surge, the tuner went out... They turned out to be smart people, they disassembled the device, replaced the fuse. The tuner worked. I brought it to me and turned it on. but did not connect it to the antenna. I flashed 5.46, connected it to the antenna, but can’t see the signal.
According to your words, if there was a voltage surge, then first of all change the 47MkF 100V kander and secondly check the tuner voltages.
HERE WE ARE NOT EXTRASENSE OR CLAIRVOYANTS.
16.03.2010, 19:12
That's the trick, I wouldn't ask for advice, the voltages are all normal, I checked them with an oscilloscope.

Recovering receivers using Jtag and Jkeys
The result of failure of the receiver software is for two reasons:
1. Unsuccessful firmware;
2. A crude version of the software that disables the receiver.
In this case, “BOOT” lights up on the display and the receiver does not respond to anything, including the remote control.
Let's look at the procedure for restoring the receiver using the example of an unsuccessfully flashed SkyOn 2300.
Recovery occurs in 3 stages:
Clearing the receiver's flash memory;
Uploading factory software;
Flashing with the latest software version.
Clearing the receiver's flash memory
To clean the flash memory, you need to connect (solder) a Jtag cable (Jtag cable diagram)
22801
to the internal Jtag connector of the receiver and to the LPT connector of the computer.
Turn on the receiver. Run the program fdddddddd22803 Select the size of the flash memory in accordance with the one installed in the receiver. In our case, 2 MB and click START.
This will load the trap.bin file.
If the ladder is normally loaded, then you can try to erase and write the flash memory.
If it writes an error when erasing, then turn off the receiver, turn it on and press START again. We no longer try to erase or write flash with Jtag Up, but run the fdddddddd22804 program in parallel with the running Jtag Up program.
Using Jtag Up helps avoid shorting the 115 leg of the STi5518 processor to ground and makes it easier to work with Jkeys.
Jkeys should detect the receiver's processor without an error window.
22805
Click Development Panel:
download and install the unlock_28FxxxC3.bin ladder at 80000140 (or 800002D0).
Next, click Flash Programming and select the flash type 3900 or 4700 (or try some others so that the flash type 29LV160 or similar is shown). Flash memory should be erased and written normally.
22806
Uploading factory software
Press the “Program” button for Chip/Selector Programming, a window appears.
22807
Click Yes, after which a file review window appears, select the native firmware. In our case, file 2300.bin from the archive fdddddddd22802
After this, programming of the receiver begins, which will last about 2-3 minutes.
After filling the indicator to 100%, click OK.
Close the program and turn off the receiver from the network.
Disconnect the Jtag cable.
Turn on the receiver, after loading the language selection menu should appear on the screen.
Flashing with the latest software version
To replace the factory software in the SkyOn 2300 receiver with new software, you need a null modem cable with wiring according to the figure:
22808
1st stage
1.Connect the receiver to the computer using a null modem cable.
2. Launch the SkyonLink40 program from the archive.fdddddddd22809
3. turn on the receiver to the 220V network and switch it to Standby mode.
In the SkyonLink40 program, press the Setup Com button and select the computer port number to which the receiver is connected and press the OK button. If the connection between the computer and the receiver is successfully established, we will see a progressor window in the program and a message about a successful connection.
5.press the Upgrade 3 button in the SkyonLink40 program - a window will open asking you to enter a password - enter 1234567 and Enter.
6. Next, a window will open asking you to select a file to download - select the file boot_2300
7.observe the process of re-flashing (d 001 - d 100, then F 001- F 100), until the message Good appears on the receiver display.
8.Close the SkyonLink40 program and turn off the receiver.
Attention!!! The 1st stage is applied only 1 time when replacing the factory software with new software!!!
2nd stage
1. Launch the Skyon 2300 Updater program from the archive.
2.Select the computer port number to which the receiver is connected (Com port button)
3.Select a file to load into the receiver (file – open – folder path - SkyOn_2300 (Ver0510)
4. Press the record button in the Skyon 2300 Updater program and turn on the receiver to the 220V network.
5. Observe the software loading process (dn 00-dn 99, then ch01-ch99), until the program reports that the download has been successfully completed, then done will light up on the receiver’s display and the receiver itself will reboot and enter operating mode.
6. Turn off the receiver from the 220V network.
7. Disconnect the receiver from the computer.
The receiver has been restored! Software updated!
OpenBox S satellite receivers are flashed using a USB flash drive. Sometimes it happens that the firmware process ends in failure and the receiver stops showing signs of life. In this case, you need to restore the OpenBox S receiver with emergency firmware using the Porter program.
To restore the OpenBox S receiver, you need to connect it with a null modem cable to the computer, having first disconnected the receiver from the 220 V electrical network.
After this, launch the porter program on the computer and select the operating mode Mode -> Software. We show the path to the firmware of the OpenBox S receiver of your particular model. The COM port number can be found through the device manager by right-clicking my computer->properties->device manager.
Then you need to click the Download button and plug the receiver into a power outlet and wait for the firmware to finish.
After the firmware is installed, the word End will appear on the front panel of the OpenBox S satellite receiver, the receiver will reboot and will be in working order again.
If the Porter program does not accept the firmware you have chosen, try the factory firmware from the official OpenBox website, and then flash any other firmware in the usual way via a flash drive.
The second interesting option proposed by the moderator of the OpenBox fan club. The method is suitable for flashing OpenBox receiver firmware if you don’t have a null modem cable at hand.
- Turn off the receiver at the rear using the toggle switch.
- We insert into the receiver a flash drive, pre-formatted in FAT32 format, with a single firmware file recorded on it (.IRD file).
- Turn on the receiver with the toggle switch while holding down the CH ^ button, which is located on the front panel of the receiver.
- We wait for the firmware to start, after which we release the button and observe the process of writing the firmware into the receiver’s memory.

And here, also in order not to repeat important points, I recommend that you first read the preface to the article:.
In this case, most often you will have to turn to two general options for set-top boxes on any processors - a universal remote control or programmer, and proprietary options for ALi will have their own specifics.
So, if after unsuitable firmware the set-top box still boots up, but the remote control stops working, then we buy a universal remote control, for example, discussed in. Having selected the code and received control, we return the original firmware.
Or we leave someone else’s one if everything works fine with it.
In addition, an essential function appears with it - learning from the old TV remote control, i.e. It will be possible to use only 1 remote control, and not 2 (set-top boxes and TV).
Undoubtedly, the most universal, but also the most radical option is to unsolder the flash memory, program it with the original firmware and solder it back.
Of course, you can try without desoldering, through a clothespin adapter, but in addition to its cost of 200 rubles, you need to somehow resolve the issue with powering the flash drive on the board, because not only is it connected to +3.3V, but the programmer will not pull the extra load, Therefore, for programming reliability, most often the flash still has to be unsoldered. And then, of course, solder it back.
Before connecting to the set-top box, I recommend that you first check the operation in any terminal program, for example, in (HyperTerminal), connecting TX and RX to each other.
If, when you press the keys, the symbols are repeated on the screen, then the connection is working.
And if something still doesn’t work out when connecting to the set-top box, then try swapping TX and RX.
At turned off console, launch the program, specify the COM port, firmware file and click Next:
Messages will appear Synchronizing STBs... And Please reset target!
At this moment it is necessary turn on set-top box and downloading via UART will begin.
M38xx series processors have TX and RX pins:
- ALi M3812 - 114, 115
- ALi M3821 - 8, 7
- ALi M3821 P — 8, 7
However, this utility when connected to the M38xx after synchronization Done, gives an error message Set stb memory error:
Perhaps a more modern utility is required specifically for the M38xx series, but so far I have not come across one.
Of course, traditionally ALi processors always have pins:
or, at a minimum, the corresponding control points on the back of the board, going to the processor pins:
| ALi | M3812 | M3821 | M3821 P |
| 1 TRSTJ | 109 | 105 | 40 |
| 2 TDI | 110 | 106 | 41 |
| 3 TDO | 111 | 107 | 42 |
| 4 TMS | 112 | 108 | 43 |
| 5 TCLK | 113 | 110 | 44 |
| 6 GND | GND | GND | GND |
However, despite the ease of connecting to EJTAG (for example, through the LPT port of a computer), the main problem, again, is the lack of proprietary programs (that know the structure of M38xx processors).
If anyone knows of certain utilities for the M38xx, please write in the Comments. Thank you!
And one more option for ALi processors, but not Emergency Recovery, but - Automatic update via USB— without even touching the remote control or front panel.
I’ll immediately stipulate the key condition and main disadvantage of this method: it will require new software version, i.e. the firmware with which we will update the set-top box should be version higher than was installed.
In order to flash the receiver automatically, you need to rename the unpacked firmware file to auto.abs(or auto1.abs, auto2.abs), place it in the root directory of the USB drive and connect the drive to working to the receiver.
After the system recognizes the USB drive, the update process will begin automatically, and you just have to wait for it to finish and auto-reboot.
Update modes:
- to update in " BY"("main codes") the file must have the name: auto.abs
- to update in " Software+channel list"("all codes") the file must have the name: auto1.abs
- to update in " Software+bootloader"("all firmware") the file must have the name: auto2.abs
Using World Vision Premium as an example, we rename the new firmware version to auto2.abs and connect the USB flash drive to working receiver.
As usual, the flash drive will first be detected, and then automatically The standard flashing procedure starts:
at this time messages appear on the console:
shugltest usbupg_item_sel_callback event:1,bID:1,param1:16
shugltest usbupg_item_sel_callback event:13,bID:1,param1:0
shugltest usbupg_item_sel_callback event:2,bID:1,param1:16
shugltest usbupg_item_sel_callback event:1,bID:2,param1:16
shugltest usbupg_item_sel_callback event:13,bID:2,param1:4
shugltest win_usbfilename_remind tempstr_len:19
shugltest usbupg_item_sel_callback event:2,bID:2,param1:16
shugltest usbupg_item_sel_callback event:1,bID:3,param1:16
shugltest usbupg_item_sel_callback event:2,bID:3,param1:16
user_mem1.buf =
user_mem1.buf =
user_mem1.buf =
--sys_watchdog_reboot-
and the console reboots itself.
If you then slip it in again auto2.abs, then there will be no more flashing, because the same version is already installed.
So, 4 options:
- Universal remote.
- Programmer.
- For M360x via UART.
- Automatic update via USB.
As noted at the very beginning, most often you will have to use the first two universal ones. But nothing prevents you from trying the last two methods first.
Well, as usual, it’s worth reminding again:
EVERYTHING YOU DO WITH YOUR CONSTRUCTION IS AT YOUR OWN RISK!
Although this is unpleasant, sometimes this happens and satellite receivers fail. Mainly when an attempt to flash the device's firmware fails.
Today we will try to help with such a situation, in particular if satellite receivers of the brand fail U2C.
How to restore a U2C satellite receiver after unsuccessful firmware?
It happens that during the firmware process the light went out or a child pulled the cord out of the socket, or simply the firmware file turned out to be “broken.” In short, the result is obvious (sometimes it can be done).
We have a “dead” satellite receiver.
The first and easiest method for restoring U2C is to try to reflash it from a flash drive in this way force_upgrade_rom.bin.
However, the firmware you need may also have this name - just rename it and throw it into the root of the flash drive.
How to flash U2C from a flash drive?
Option 1: Oldest bootloader:
We insert the flash drive into the receiver and connect it to power (the process will start automatically).
Option 2: Second version of the bootloader:
We insert the flash drive into the receiver, press the OK button on the remote control, and connect the receiver to power.
Option 3: Latest bootloader version:
We insert the flash drive into the receiver, hold down the button on the front panel (for receivers U2C MINI: button on the left; for receivers U2C MAXI button in the middle), and connect the receiver to power
After the process is complete, remove the flash drive.
If the receiver still does not respond, and you have tried with several flash drives and “clean” (without channels and keys) firmware.
Second U2C recovery option– let’s move on to preparation and firmware via COM Port. Why preparation - yes, because res U2C does not have a standard rs-232 connector, that is, COM. He has a minijack there.
We solder according to this scheme.
Then we move on to the firmware using this U2C S+ RS232 Restore or the old version of R estorU2C.zip.
Select the com port number, rename the firmware to a file rom.bin, and start the firmware process.
Afterwards a window like this will appear.
Don't touch anything. After the process is completed, you should receive a working device.
If not, and nothing succeeded, then the next stage will probably not be within your power. Since the bootloader or even the flash drive was damaged in the receiver.
The subsequent procedure involves unsoldering the flash drive (possibly replacing it) and flashing the bootloader or dump using a programmer.
