    NEVER use HiTool, as well with H92H you can always restore by USB.
    The H92H has as well USB boot and you can just use a basic image to update and restore it
    How???, if USB does not work and the box is Bricked, how can you flash with USB, all kind of devices can be bricked, mobile phone, android box, etc, there is no need for you to repeat the same thing without meaning, here is another user saying the box was recovered with HiTool: Zgemma h9s Dead-Bricked

    @Shqiponja:

    OK. First of all, perform the basic diagnostics via the RS-232 serial interface, as I mentioned above.

    The CFE boot-loader may not be flashable via the RS232 interface, but should be flashable via JTAG. Your device should have both interfaces inside the box, on the PCB board - more info here: How to connect JTAG and RS232 port - Zgemma Star Series

    If RS-232 diagnostics do not work with a serial null-modem cable (for example, using a PUTTY application as a serial communication console), then the error will be really serious - probably an electronics / hardware error. Then you can try flashing the CFE boot loader via the JTAG interface, but it probably won't help with such a serious problem. Therefore, by flashing the firmware, the HW error cannot be corrected. In this case, take the set-top box to an experienced electrician, who will service the set-top box and replace the necessary electronic components on the PCB board. And of course, only if it can be replaced at all because a "chipset" such as a CPU is stupid to buy and replace (a lot of money and a lot of work to replace) - it's better to buy a new complete device.
    The problem is, I do not have the RS232 Cable, I have to wait for 2-3 weeks to come from China, what you show me above is for Zgemma H5 series, not for the H9 series, H9 series can be flashed as software all together with HiTool, I will write here when I get the cable, if I find that cable here I can test early, Thanks for helping.

    Probably it's difficult for understanding as you think bricked means that USB is as wel not working,
    Bricked is that the software on EMMC or NAND is damaged and that it cannot boot the fastboot (cfe/bolt) loader.

    USB-Boot is a process what runs in the main chipset and it's a select from which storage device you want to boot.
    By activate USB-Boot it will read the fastboot from USB and this can never been bricked.
    When USB doesn't work it means your hardware is damaged and not bricked.

    Buying RSR232 is wast of your money as you can fix your box easily by USB stick. It's actually the same as install a image.


    SO, DON'T USE HITOOL, THE RIGHT WAY IS USB BOOT!!!!
    You can even start the box from the USB when you remove the NAND flash.
    Why damage your box and the warrenty by using Hitool and RS232. The box is design that it never need this tool.

    The USB-to-RS232 interface for your PC, you can to buy anywhere, even on eBay. It is also commonly available in electro-shops with IT components. The RS232 null-modem cable can also be purchased everywhere (it can also be manufactured if you buy the correct 9-pin RS232 connector). Some PC machines or laptops have an RS-232 interface built-in (as a connector on the back of the case), so make sure you check this fact with your PC!

    Since your Zgemma set-top box does not have a physical rear RS-232 connector, you need a "DIL" connection to the PCB. So, after purchasing the null-mdoem cable, remove both connector covers. Now you will see which RS-232 pins are used for which wire color. Then cut one end of the connector with a knife or desolder the wires from the 9-pin RS-232 connector. Connect the DIL connector to the cut / solder end of the cable.

    USB-to-RS232 interface (adapter) for PC:

    NULL-MODEM cable:

    DIL 2.54mm single-row:

    Perhaps you should leave it to more experienced electricians, as you do not know the RS-232 interface (which can be purchased today in any electronics or IT store).

    GoodLuck

    It's good you want to help but with this info you will kill your hardware.
    I do really not understand as USB will always work so why it's talk hier about RS232. That is the major advance of buying a Zgemma H9* that by USB you can always fix a brick box.

    If people want to spend unneccessary money and struggle with Hotool it's fine by me.
    The Zgemma has the header on the PCB so not need to solder it on the mainboard.

    Hardware need for Hitool:
    USB to RS232 converter.
    RS232 to TLL converter (With 4pcs dupont cable)

    Software:
    Hitool
    XML file with partition layout

    @WTE:

    I did not advise him to use any third-party APPs.

    I warned him several times that if the diagnostics via RS-232 interface does not work, the set-top box is dead and the intervention of an experienced service technician / electrician will be necessary.

    He complained that he couldn't get a simple "USB-to-RS232" PC adapter and also a null-modem cable to connect the device to a PC machine. He mentioned yet that he had to order from AliExpress and then he had to wait 2-3 weeks (which is also misleading info, because AliExpres sends the goods very quickly and the 2-3 weeks indication serves only as a reminder for the maximum possible delivery time) ... so, I explained that there is no problem to buy all these necessary things "at home" (I don't know in which country he lives, but today it is not a problem with these things and it is not necessary to use Chinese AliExpress, but regular eBay).

    OHH yes ok well, talk is cheap show me the code, I have tested 5 USB formated with all kind of tools nothing, if you know how to do bootable USB for my Zgemma please write guide here, Thanks.

    I got the cable today testing but i get the following error, when I try to flash fastboot with Hi Tool STB:

    Failed to send head frame, possible causes are as follows:

    1. The Fastboot mirroring the current single-plate type mismatch;

    2. Board problems with the DDR, DDR initialization failed operation.

    failed to send type frame

    Failed to download fastboot!

    Maybe I need to make XML file with partition layout for Zgemma H92H, can someone help me how to do that?
    Thanks
