    very good
    I changed it to this deco icflash and charge everything ok picture
    the problem is that the v4 update in some decos gives problems with the tuner and locks the deco
    Where is the update saved?
    Is it possible to repair?
    thank you very much

    Software spdates are first saved (at least a part of it) into the memory, and then to the nand flash chip.
    Mcu upgrades are saved to the Mcu (decoding) chip, that is, if it's a clone.
    Other upgrades may stored into a sector of the cpu.

    In any case, if you have a box which is bricked, and it's related to the bootloader, of nand flash chip.
    Then it can be fixed by jtag (I2C) but to do this you need the cypress board and broadcom software etc.

    If the Mcu chip has been written, and become corrupt due wrong data to it, then the only way to fix this is to replace it for a pre-programmed mcu chip.
    However, with a corrupted mcu chip the box should just work, but the tuner reception will fail.
    If the box failed to boot, even without the mcu chip, then it's in most cases to repair by jtag (I2C).
    Or replacing the nand flash chip for one which is programmed and suitable for the type motherboard..

    the decoder works and starts perfectly
    what happens is that when you put some channel you see but it locks
    so I asked where the update was v4 v4 that apparently blocks some tuners

    Basically, you need only the v4 upgrade if you want to use the v4 image files.
    Block tuners.. it depends on what you mean,
    1. Tuners no longer present.
    2. Tuners works on fta channels, but not on pay channels.
    3. Tuners works only if I add the channel lists manually.
    4. other issue.

    1. Mostly hardware failure.
    2. Issue with the card reader or card or in some cases the software needs a active cccam in order to work also with a card.
    3. Mostly a image file issue or some issue with the dish hardware settings.
    4. ....

    I explain the deco brings the update v4
    the picture starts perfectly
    the problem is that when you put or search channels when you have 8%, the deco
    so law is a problem of bad update v4
    I can reinstall or know where it is installed
    to try to change the chip thanks

    Normally the software, or upgrades as bootloaders are installed into the flash rom.
    Only if you had used a mcu uploader, then it could change the mcu security chip.

    Replacing the nand flash chip for a new, empty one is a option, however you need to jtag (I2c) the box to upload the boot loader, or use a pre-programmed nand flash chip.

    Upgrading to the v4 is a bit risky, it could fail with the result that the box become a brick.
    It all depends on which type motherboard and security chip your board has, because as for clone boards there are several types which were produced by different fabrics.

    Nevertheless, even if it has become bricked then there are ways to bring it back to life, what I mostly do is to replace the nand flash chip with a prepare chip, made on a motherboard which has a nand flash chip socket.

    In any case, yes there are risks, it works, or don't.
    It's up to you to preform it, I can not guarantee that it will be save to do.

    Most likely the same mobo as I have here..
    IMG_1082-solo2-L.jpg

    And the upgrade to v4 passes the MCU chip, after that it flashes it to the fpga chip.
    But if the box just starts, then it should not be a problem when you use the v4 image files.
    When failed you need to jtag the box and prepare the nand flash chip with the cypress interface.
    If you don't have the bbs software, and bin file for it, then I can give that.
    But still, you need the CY7C68013A EZ-USB FX2LP USB2.0 Developement Board/module to be able to jtag the board.

    Or, if you not have this, then you could also use a pr-prepared nand flash chip.

    But if you ask for the v4 image files, just use google and search to, solo2 lonrisun v4

    See my previous image, left under
    However, if your board has no security mcu chip, and so that area is empty then it could be a vu solo2 genuine (original) motherboard, as far as I known only clones have the mcu chip..
    If that is the case then you probably need to use the original/genuine software, and not the clone version, and may also explain why you have those issues by using the clone software on a original box.

    Something as this,

    to several users that was the solution
    but it does not connect me to update.exe
    I have this connection

    The wires are correct, but the update.exe may for a original box or you missing a step.

    I think...
    Upgrading to the mcu chip work as far a I know with hyperterminal.
    First start up the update.exe, leave it as it is close it when it's done and start hyperterminal and make the connection bps 115200 etc.
    When connected, turn on the box and press on the keyboard 012345
    If all goes well you should see in the terminal, Mcu connect to the flash successfully.
    Press key 1 if you have a successful connection and it's going to waiting for file to be sent.

    Goto in hyperterminal to Tranfer end choose Send file etc..

    However, in most cases it will not connect to the Mcu chip, reason not really known but as far as I see it it only works for one type solo2 clone board.

    there is no way to connect it tells me that port com 1 is open the hyperterminal if I throw the data but the update exe dead
    Could you change the chip where the update is hosted?

    sorry i had the null modem cable
    and with this if there is connection
    with the other it does not connect anything

    By using a null modem cable which is 2 to 3, and 3 to 2..
    In that case it's 2 to 6 and 3 to 1

    And yes you can change the Mcu security chip if you have the same chip from another motherboard.
    You can not chance the chip for a brand new one, because they are programmed for the solo2.
    In some cases you can use a security chip from another type box, but it must be the same chip, and you need to have some luck if it works or not.

    No Way to connect to the cable
    Tell you what
    with the null modem if I have communication
    the mcu chip does not come screen-printed
    Do you happen to know what the reference is?

    Just tested with a solo2 v4 upgrade.
    Started update.exe
    Turned on the box and its start the download, and completed.
    Closed the program, Switched the box off, started hyperterminal bps115200/no/1/no and connected.
    I get first -***** and then the text if you want to download etc...

    If you cant do the update.exe than I think that you have a issue with the rs232 chip, probably the read part
    That is, if you are sure about your serial connection, in any case the solo mcu chip can only be reached by the pins 1 and 6.
    The 2 and 3 are for reading the box.

    And just to be clear, the update.exe only upload the program to get reach the mcu chip.
    After the upload it remembers it until a time has past, or the box has been switched off two times.
    It does not do the programming to the mcu chip, for that it needs to be done with a terminal program.
    The text, if you want to download etc... is from the update program.
    By not using the update.exe you will only see in the terminal some characters above the screen.
    If you not see that, then there is probably a issue with the rs232 chip, most likely the pin 1/6 part.
