Samsung Chromebook Firmware

[Jimmy Ruan]

I have flashed nv_image-snow.bin from this guide http://krblogs.com/post/63809988096/bootloader-unlock-on-samsung-arm-chromebook and now i kinder want to reverse the chromebook back to normal. The problem is i don't have my backup. How can i get the firmware so i can flash my chromebook back to normal?

you can download a daisy recovery image, unpack the rootfs, find the updater tool in there, unpack that, and it should have a signed firmware blob.  if you haven't already blown away your device-specific info (like your device's serial #), you'll need to merge the two coreboot blobs by hand (e.g. extract the u-boot payload from the good one and insert it into your current one) before flashing.  otherwise, you can just flash that blob directly.

i vaguely recall this procedure being discussed in this group or the chromium-os-dev group, so you'll prob want to search the forums for more details.
