@fabiobassa @jock you both are master-gods with the power of every god from all the mythologies known by the human kind! Next step for me now is to install it to the eMMC (if that's not possible, I will stick with SD boot only, no problem). I heard that there is the armbian-install command, so I will try it since the provided image is a XFCE Desktop one and I want a minimum image to free up resources since I just need a headless machine... Any suggestions for guides/documentations to install a minimal enviroment to emmc from the SD desktop enviroment?

please ignore my previous comment. THE EXPERIMENTAL IMAGE DID BOOTED FROM SD CARD! IT WORKED I have forgotten to erase the flash on the first time... After I erased, it booted from the SD Card. I cannot thank you guys enough!!!! <3 <3 <3

@fabiobassa and @jock, thanks for your quick responses! You are true heroes for this community. The suggested experimental image have not worked for me unfortunately. Same behavior, no Video and no Leds. However, a little progress on the UART search... Connecting my RX adapter pin to the SD Card 4th pin gave me the biggest console output so far, even though its just garbage, I see it as a little progress... Please see the attachment. Also, I think I was able to identify that the Samsung chip is a 1gb/8GB one from the "rkdeveloptool rfi" command... see it below with some more output from the rkdeveloptooll...

Hello Guys, This will be a long post, so I already apologize for that! I am trying to install armbian in the most generic MXQ PRO 5G 4K ever. No joking when I say it’s generic, because I have some proof that this Frankenstein monster is actually a MX9 and a MXQ 4K PRO merged together. Here are some board Details: MoBo: MXQ-EP-2-V1.0 CPU: Rockchip RK3228A Wifi: SV6256P Storage: Samsung KMQ7X000SA – B315 (Is this a ECMP 8GB+8GB or a emmc?) I call it a MXQ Frankenstein, for the following reasons: According to the info and the picture from this source, the “MX9 4K 5G” has the exactly same MoBo “MXQ-EP-2-V1.0”, but with the SV6152P wifi instead. According to this other forum post, the OP has posted pics from his "TXC2-MXQ-EP-V10” MoBo, which looks basically identical to my “MXQ-EP-2-V1.0”, but it has the SV6152p wifi like the MX9 4K 5G, but with a RK3229 CPU instead. This post was very useful for me because of the Short Pad for Mask Mode for this version is the same as mine. In this other post, we see the same “MXQ-EP-2-V1.0” Mobo, but with with a SanDisk storage chip instead. And in the same post, in the last comment we see another user with a 8GB/128GB variant with the same SV6152p wifi from the above “TXC2-MXQ-EP-V10” So including my version, it seems we have at least 5 different versions of this horrendous Frankenstein device, for the “lowering cost reasons” we already know…. Despite many tentatives, I am not able to make the “multitool” (or amrbian directly) to boot, from any method. Tried many times from SD, from USB and even after it is copied directly to the eMMC, all following the guides from the 1st page from this post, but also from other internet sources. Simply I’ve got a black screen output whenever the SD Card with multitool or armbian in inserted, with no leds turned at all. Unfortunately I have not done the backup from my original ROM before I have tried to write armbian directly to the emmc, because I did not know that was possible back then, and now I’m also not able to find my original ROM. I have tried many (10+) different ROMs, flashing from Linux and Windows, but I ending up having the same behavior as booting armbian, with no Video and no LEDs, until I finally came across to the ROM called “MXQ-EP-2-V1.0_SV6152P_OK By: (Zer013)” from this site. With said ROM, I was able at least to get the HDMI video and LED’s blinking, but I got stuck at a boot animation loop forever. For some reason, only when I flash it from Windows using BatchTool or RKDevTools it works. At least I was able to test different Loaders, and with this ROM, I have tested successfully all the loaders below, either flashing by Linux or Windows. (Remember: The device gave video and LEDs, but I still got stucked at ROM’s boot screen): RK322XMiniLoaderAll_V2.47_spectek_en_ddr2_rd_odt_171209.bin – This was extracted from the above ROM image that give me workin LEDS and HDMI Video rk322x_loader_v1.10.238_256 from a 2020 comment on this thread from a guy trying to overclock his ddr memory. rk322x_loader_v1.10.238_256.bin from first page, from the “Installation (without SD card, board with eMMC)” section I was trying to flash different loaders in hope that some of them would make my armbian to boot from the SD card, but without any luck unfortunately. I have also tried to erase the flash completely to force the SD Card boot, but I have got the same no-screen / no-leds behavior. If anybody has any ideas on how to go further to install armbian in this board, I would appreciate a lot! I don’t need the wifi for the purpose I intend to use it, so minimal installation is more than enough for me. I’ve been turning it on mostly with just the USB cable in the OTG port, so at least I can check the device status with lsusb in linux. Sometimes I do some tests with the power cable turned on, and I have noticed the same behavior as well. Does it make any different to turn it on by USB or Power Connector? I’m still not able to find the Serial UART pins, even after I have tried soldering my USB-TTL in different points of the Board as there is no printed info, so this also adds to the overall complexity. Despite my efforts with the multimeter, I was not able to identify them yet. Since I’m afraid to burn another USB-TLS adapter, I’m being cautious and only using the GND and RX pins from the adapter. So far, I have found 2 interesting pins, but they only give me gibberish text, despite trying different baud rates (I have tried them all). Most promissing PIN for now is the pin labeled “K” in the pic below, as it is the one that gives me more output when the device is booting, almost in the same time as a normal system boot… So my “guess” is that the Pink K is the board TX pin… Attached there are all the photos of the mentioned components from my board.
