Re: Please I need to clear me dump...

Thank you, brother, for your interest.

The problem I am facing is that the devices are locked with a password associated with the serial number (Like as the iCloud on iPhone)

Re: Please I need to clear me dump...

I was trying to Clear Me dump for trying to lose the serial number
Because one of the devices I found a dump here in the forum when programing it, the device mated the password lock ( Because the serial number has changed )

Doesnt really matter whats the chromebook model.

Here are the files. Flash them. Try accessing devmode (you will fail but you would need to do it.) After restart you should be able to log in using a random google account. From there, do a powerwash. Now it's unenrolled and devmode unlocked.

I'll do the first one, you do the rest and learn. Hint: compare with hexeditor.

Not to the unlocking,but it does matter to the thread title and google indexing. The original thread title was "Please I need to clear me dump..." so at first i assumed he wanted the ME firmware cleaning

The modification that you made to the file. You made the same amendment before the topic was brought up in the forum
But to no avail

Re: Please I need to clear Lenovo 500e chromebook

I press the ESC key and circle key on top of the keyboard, takes me to dev mode then it gives error of no operating system found. It also gives out the exact model and the chrome webpage, so I just open chrome, and go there, download the extension, open the extension and download the operating system on an 8gb USB drive. Use that drive on the chromebook and wait for it to finish. Last time I did four, so I used only one drive, all same model.

I can see the webpage and model of your chromebook on the third picture, just go there.

As I said, you need to go to dev mode. It will not let you, but you need to go there anyway. Then you would need to let it go back to normal mode. There, it should let you sign in with any account, instead of school/company account. Log in, do a powerwash.

Re: Please I need to clear Lenovo 500e chromebook

where is the bios chip located on this board does anyone have a picture?

Re: Please I need to clear Lenovo 500e chromebook

in a white square

So how do I dump the BIOS on these devices? 500e gen 1. Do I need to open the device and use some flash reader directly on the chip? If so, which reader do you recommend?
