So, here we have some fun findings. Using the usb 2.0 male to male... No change. Nothing is in rockusb mode or maskrom mode... So, screw it, short the emmc pins, or which ones I have a belief in being... success!! Maskrom mode! So, can I flash anything, yes, one img file, an android x88 pro 10 build. Anything else, nope. None of the tools accept any armbian img as valid. (Windows that is, Linux wasnt happy today) So, I can instal the image fine, it's android 10 by the looks of it, no WiFi however. Multitool will now work...no matter the img flashed using the tool, none boot and I'm left having to maskrom and start again. So so odd 😅 Picture is the pins on the back for maskrom Right hand side has one pin. Left has two, it's the right one of those two that you short to the right side pin. I've marked the pins in yellow and blue for ease. https://ibb.co/Y2fWyRY

@jock I have ordered a usb 2.0 male to male, arrives tomorrow. Hopefully this rules out the usb 3.0 male to male I'm currently using. In the mean time I shall take some high resolution images of the board and what I believe are the various points. Hopefully this little endeavour can help others. I have noticed just how much help you give to various forum posts @jock I for one am very grateful for the help and knowledge you have passed along. Thank you Hope you had a fab new years.

I believe my device is dead. Nothing shows under lsusb sudo or otherwise. Nothing shows on HDMI output, can't load the sdcard due to it being the ext type. So I think I'm at a loss. I can upload some high detail pics and where I believe the clk point is asap. Thank you once again for all your support.

@jock I shall try again tomorrow. Thank you for the info. I did try lsusb, however nothing was detected. I only have a usb3 a to a male to male. That wouldn't cause any issues would it? As the cable should be electrically backwards compatible. I'll remember it's the usb2.0 that's the otg. Thank you once again.

Thank you, I have done a bit more investigation. If it's in maskrom mode it should appear as a device when a usb a to a cable is used. However under windows and Linux no device is shown. I can also use a usb to serial device and have connected to the three pins marked gnd, Tx and Rx. No matter what baud rate I use, nothing appears. It's like it has no sign of life. I can make out what I think are three test points on the back of the PCB near the emmc on the front that could be the clk, however I am unsure. Pushing in the button inside the 3.5mm jack doesn't do anything. Holding it for 3, 5 or 30 seconds doesn't make a difference. Nothing I do makes this device show up. All was fine until I used multitool to erase... Now, I do have a backup of the emmc made with multitool, however burning it to SD doesn't do anything, same as burning any img to SD using etcher. Do I have a dead board somehow? Thank you

I also have an X88 Pro 10 I managed to run multitool, backup and erase, however now it wont show up anything. wont sd boot. wont show with usb conection to pc. nothing it powers up. So maskom mode was my fall back, is the image is avaliable elsewhere??
