@jock Hi, yes - that is what i meant. Thank you for the hint. I was able to install Arbian (buster edge 6.5.5 minimal) with some older version of multitool (because of the limited space, that newer have, for image file). And there again that timer, after installing armbian i've got that 60 sec period - the device is not bricked, i was able to reach the point to set a root password (after few reboots) - and it boots normaly to that point. In my thinking there are a timer by default, which is disabled somehow from original image, and after an event - erase emmc or instal another OS or brick the device - there are no suppression on that timer. Very strange.

@jock I was able to repair the box with FactoryTool - it was able to erase the emmc, that no install the image (in loader mode). Right now in that memory there are an original image of that it come with (it is ubuntu with compiled Andorid 7), but i still want to install armbian in emmc. The interesting moment here, is that when i've got working image in emmc the device don't want to boot from SD or USB (tried with reset button and even with a procedure which i did to enter in maskmod). I've got a working procedure (if it bricks again) so maybe i'll try again with multitool and another image of armbian (which i tested last time in maskmod).

@jock mutitool can't find the eMMC (even for erase). I was abble to repair the box with FactoryTool. Now the problem is, that the box don't boot from SD or USB to install Armbian (i have a working image for this hardware). Tried to put it in Loader mode (with reset button) and in maskmod.

@RaptorSDS Thanks, i'll try this two versions. @jock It more looks like it hang (not reboots). I think it's kind of timeout timer inserted in MaskRom mode (read in other forums some box has that option), but how can i remove that option with no access to the box. I've try to erase the eMMC from the AndroidTool_Release with no success. May be some other tool of Rockchip can be used (in that 60 sec interval) to erase the eMMC or change the interval (i've tried with FactoryTool_v1.64 - still no access in MaskRom mode)? That's why I look for older version of multitool (may be it will be able to erase it).

@jock Thank you for your reply. I've tried with that version in the first page - when i brick the device, it started the flash with that multitool - get around 60% and than reboots. After that multitool says there are no eMMC. Can you please share the older version of Multitool (build 52d0101 14 Mar 2021)? Thank you in advance.

Hello, there is a lot of useful information on the whole forum and particular in this topic on a specific problem. I'm trying to restore a TV Box that I bricked myself by putting the wrong image inside (I didn't try if image boots before that). Hardware: MXQ PRO 5G (rk3228a, 1GB RAM, 8GB) I was able to get the device into MaskRom mode and successfully boot from SD card. I tried to flash an image using AndroidTool_Release_v2.69 but it gives errors for any type of device operations. My problems are: 1.The memory of the device is eMCP and the latest version of multitool does not see it... In the forum I saw screenshots with a version of Multitool "build 52d0101 14 Mar 2021" which has more options (maybe support eMCP) but i can't find this version anywhere... 2.After putting the device into MaskRom mode, I manage to launch Multitool or even start to launch Armbian, but after about 60 sec. the picture disappears (apparently, the device does not restart, but stops sending a signal via HDMI - and the LED continues to glow blue) I have found a version of Armbian that runs on this device and wanted to try installing it from the SD card into the eMCP, but this 60 sec problem catches me at the moment where I change my password. Have you had similar problems with these or any other type of devices? Can you advise me how to revive the device? Thank you in advance for your time.
