Unable to recover Chromebook

Have you tried this Recover ChromeBook

Hope this helps

Thank you Alfredo,
Yes, I have followed the steps but get stuck on: “The device you inserted does not contain Chrome OS”
I also followed the recomendations to troubleshoot: "First, make sure you have used the correct flash device or SD card that was used to make the recovery image media. If you are using the right one and still the problem remains, the storage device might not work. Try to use a different one and follow the steps again"

I have jumped into 4 USB devices and none work. They all say the device does not contain Chrome OS.

Is the stick you are trying a SanDisk?  They do not work on Chrome OS.
Just deleting partitions also may not do it.  Try reformatting the stick FAT-32, or NTFS on the Windows machine or try with a kingstom stick.

I also read that ScanDisk don't work, the one I am using is Lexar; don't have a kingston but may need to get one.
Let me try to reformat to NTFS. thank you.

Best to try FAT-32, especially if this is an older Chromebook.

Thank you, nothing has worked so far. Going to purchase Kingston USB and try.

Just purchase a Kingston DataTraveler G4 USB drive, installed the recovery image and got the same message: "The device you inserted does not contain Chrome OS" AAAGGGGRRRR!!!

Any other ideas??

Have you tried the option at this link??

Hope this helps

None work, I called Samsung support and they want me to send the unit for checkup.
Thanks for the help.
