I need to show my project tomorrow. Please help!

[odroid]

Flash the OS image again let us know the result.

[Julia]

How to flash it, via sd connector? Where is os image?

There is all my work, it takes 1 day to bring back all environments (( Is this the only reason? Is system can crash just like that?
I want to clarify system reliability and stability.

Blue indicator blinks, but system does not starting

You can connect your SD or eMMC to your Linux PC to backup your working directory first.

Sudden power-off might cause the OS corruption.

Please read the User Manual first for flash the OS into your eMMC.

I cant flash it

There are several problems
1) When I connect my eMMC to PC(Windows 7) it see only boot section (128Mb)

2) If I am trying to flash eMMC it just automatically unmounts. I have 2 eMMC modules and 2 adapters and tried on 2 different computers (Windows 7 on PC and Windows 10 Virtual Machine on MacBook) but same errors - immediate unmount while writing (when I press "Write" button)

P.S. Before my tryings blue indicator blinked, now not, not even old messages on start just "No signal" ((((( I dont know how to fix it, it is very important project for me(

[Julia]

I also tried dd with no luck. And Disks and Gparted - same issues - unmounting on ANY actions.

[odroid]

Windows can see only 128MB. It is very normal because Windows can't detect EXT4 file system.

Your card reader might not be compatible with the eMMC.

Or try to connect your card reader to USB 2.0 host.

[Julia]

Finally, I solved this problem.

I bought 8(!) card readers. And only one managed to flash eMMC. Unfortunately I lost all data, but I have backups, it took some time to restore all system configurations, but it works now.
And one more thing worked only on Linux, Windows still unmounts device.

Some USB host ports on PC also have the power supply issue.
So it is worth to try other USB 2.0 port or an external powered hub.

Anyway, good to hear you solve the problem.
