Use this dump. Turn on laptop, boot to recovery mode (esc, refresh and power, hold esc + refresh until in recovery mode). Press ctrl + D, press enter. Press ctrl + D and press enter again. Don't remember the exact process but the idea is to try gp tp developer mode. It usually says that dev mode is disabled but that does not matter yet. Anyway, you just need to wait until laptop restarts. It should clear all data. Then just let it boot normally and log in with your gmail account. Then go to settings and powerwash. After you powerwash, dev mode should be unlocked and you should be able to use any gmail account.
You can use bios chip Winbond 25Q64FW. Fw is 1.8v bios chip.
thanks bro i tried this chip and it worked but the problem is that i cant activate the device cant login !! so im assuming that the chip is not working
I haven't work with chrome laptops that much. but I have unlocked a few in the past. it is very rare to receive a chrome laptop with a bios password. the problem I've seemed with chorme laptops is admin password, which have nothing to do with the bios but with the google account. in my case I have taking them apart and remove a screw to gain admin control. so the chip .bin that was shared here is not going to solve this issue. as for the activation, the .bin file is not going to help either.
Flash this, try to switch to devmode (you probably cant but that doesnt matter). Let it restart normally after that. You should be able to log in now. After logging in, do powerwash. After powerwash, it should be unenrolled and with dev mode unlocked.
butttttt I tried 45min of your instruction...and every time when i try to LOG IN ,I have to connect it to the internet...after that, it locks again !!!
in the end I tried last chance:
on another chromebook i made a bootable usb with new chromeOS for this model(on motherboard is 300e/500e 2nd Gen)
i installed new chromeOS on Lenovo e300 and after Power On , i try POWER WASH (ctrl+alt+shift) and I succeeded
after the restart, I logged in normally, everything works ok
Well, I did come up with this solution and it has worked on hundreds of different chromebooks, including lenovo 300e. I have never had to install new chromeOS for it to work. But since it works for you and you are happy with it then its all OK.
