    Could be, let say that the sent (tx) part is fine of the usb to ttl rs232, but the recipient (rx) has issues.
    Than you also could get the waiting problem because it gets no answer.

    Anyways, I prefer always to have an open module so that I always have the option to replace the rs232 chip when heeded.
    And, I always use a old computer with a real db9 serial port and a Xp system for these kind of jobs to exclude any communication issues.

    USB to rs232 has worked fine for me on a laptop, I have fixed many boxes like Skybox, Openbox, Amiko, etc.
    The problem is this cable only costs 2$, not sure about the quality, but I do not have a cable with pins other than this one.
    Any advice on the good cable you have tested: RS232 to TTL.

    Thanks

    As I told earlier in this reply posts,
    I mostly use the MAX3232 RS232 Serial Port To TTL Converter Module DB9 Connector W/ 4 Jump Cables and do not have or use the cable version, thus I can not give you any good advice about this.
    But to use the one I use, you must have a computer or laptop with a serial db9 port, and an rs232 null modem cable to use this.

    But be aware, I'm talking about a rs232 serial port to ttl converter, you prefer to use an usb ttl converter cable, and these, I do not use.
    Thus I can not give you any advice which are the best to buy.

    Sorry, but I have no experiences with usb to rs232ttl cables, the few I had tried ended up into the trash bin.
    But be aware that this seller deliver it from china and has based on his info a long time to deliver.

    I see the best option is to try if this one does not work then it will be the end.
    I have not a choice but to wait when the item arrives here.
    If it takes a long time or not, nothing I can do, I can not find this Item here.
    Thanks

    Assuming that you had everything tried to do it with the usb method, thus also tried to do it with an external usb hub which have it's own power adapter.
    And the RS232TTL method also not succeed, they it could be a hardware issue.
    I think, check at least the TTL Rx/Tx pins on the motherboard by vdc measurements, I think that they should be between the 2 to 3vdc.

    Could be, and based on other forum reply's this tool seems not to be useful for these receivers.
    But, when you have no other option, than you try the things others not have done to see if it gives some results.

    Maybe, these receivers may also still boot up by using a bootable TF Card, but this is just some ideas from my side.

    Exactly this Tool works on android boxes very well . Zgemma already provided the option of recovery by reset button The company might have the idea about this
    Oh & you are right about Tf card in android boxes it plays a major role

    Here is the recovery of Engima 2 Box with Hi Tool, and someone saying recovered with Hi Tool:
    https://www.opena.tv/octagon-sf8008-4k-uhd/42922-sf8008-recovery-mit-hitool.html
    https://www.opena.tv/air-digital-zgemma-h9/43267-zgemma-h9s-dead-bricked.html?langid=1
    I'm not crazy to try something that has never been done, the other reason is All Zgemma H9 series has Hisilicon chip devices: Hi3798MV200 Main chipset, which is made by Huawei, and Hi Tool is provided by Huawei is well.
    Now if you know about technology a bit like me, I can see that all Zgemma H9 series has similar kinds of making like android, android and Linux are very similar, android is kind of diverted branch of Linux.
    I tested 5 USB formatted them in all kinds of formats nothing.
    The person says to me that after installing some kind of software the box was bricked, no hardware problem, but again you never know the box is not mine.
    I have to do all kind of tests if succeeded, if not never mind, at the list I tried.

    Yeah well, I assume you already have the HiSilicon Hi3798MV200 driver for using the Hi Tool, because this seems to be needed when using the HiTool.

    Anyways what I could find by searching with google to hi3798v200 download (yes without the m) is a 169MB HiTool-STB-5.0.6.zip file which seems to be support the Hi3798MV200, and when searching to the HiTool-STB-5.0.6.zip I could find more download places.
    I'm not sure if this is useful information for you, and maybe you already have this.

    I have the latest version 5.0.27, it has the support for Hi3798MV200, but the 5.0.6 has the support for that is well, I just have to wait for the new cable to come now, in the meantime I will see if something come up for this box, if you heard anything please write here, thanks.

    Put up a link for 5.0.27, just in case, please...

    Cable came and - any luck? Not at my end... Yesterday I bricked H9S, it seems, not USB flashable, much to WTE bemusement... :D :p :D

    Whatever detailed help/tutorials/videos on the net that I can find, deal with eMMC - like Octagon SF800x and Zgemma H9 Twin/Combo. However, I have a H9S, which is NAND, is it not?

    Now, that procedure is not to be found.

    Moreover, my USB TTL RS232 cable is not establishing contact - I can not get a serial port to choose or network connection via LAN cable. The device is set up (drivers installed in W10) but...

    Partitioning file in XML format is nowhere to be found. NAND devices have to have image made for flashing like this (according to the generic Help file)?

    In short, fuck all is ready for this kinda eventuality in our hobby, specifically dealing with our STBs...

    For starters, xml and similar files should be available to DL from HiSilicon website, when needed, directly into their flashing/recovery SW, I think...

    But... Achhh... We might have to wait for that... with plenty of booze and babes on our hands, otherwise...

    I received the new cable but did not work, I get a connection with the box, but bootloader does not download, this box maybe has a hardware problem.
    I can upload the 5.0.27 version here but is not necessary because the older versions that have the driver are fine.
    There is no need to burn the whole software, all you need to burn is the fastboot, if you manage to get the connection, read my earlier posts, maybe you are making some mistake on connection.
    Click hiburn, burn fastboot, choose flash type: nand, file: upload fasboot, if that goes well your box maybe come to life.
    Mine is not.

    Is yours has only a software problem, because this one is not mine, not sure what the problem is software or hardware, I was told wrong software flashed, but I wasn't there.

    Yeah, probably didn't quite get off booting from mSD into NAND boot and now won't boot full stop...

    And neither USB stick nor PC flashing works.... Can't get in and so - the bin...

    Well, maybe... I may have one more card to play... I'll let you know...
