Hello
Can I have help with unlocking my bios please, when I'm using RCunlocker, laptop doesn't turn on at all, can't get into recovery. Laptop model is Lenovo 100E Chromebook 2nd gen BM5866 V1.4.

Is it possible that the laptop will not work with any other BIOS just with original?

Another strange thing is that I've power wash it and laptop doesn't have chromeOS anymore now and even I can't install new by using recovery....


Cheers

Hello everyone. I have a lenovo chromebook 300e 2nd gen AST with enterprise lock. I've tried RCunlocker ( I did powerwash and install new chromeos image after using rc unlocked). But no luck with it, still locked. Is there anyone that can help me unlock it. My backup is below.

Hey everyone,

I've come across my old Lenovo Chromebook 300e 2nd Gen MTK but it's locked by an administrator, but the issue is the organization that set it up no longer exists. I'm equipped with a CH341A programmer and have identified three potential BIOS chips on the device:

1. "Pm25LQ020" BE1918 P1F573LG
2. "Pm25LQ010" BE1918 P1F573LG
3. Winbond 25Q64FW

I've successfully dumped the firmware from the first two chips but am facing challenges with the Winbond 25Q64FW, as the clip is too flat for a secure connection, and I'm hesitant to solder unless absolutely necessary.

I've attached the dumps from the Pm25LQ020 and Pm25LQ010 for reference. I'm seeking advice on how to bypass the admin lock to either fully utilize the Chromebook or at least enter Developer Mode. I'm open to using commands to alter the serial number if that would help circumvent the issue.

Any guidance or suggestions from The community would be greatly appreciated. Thanks in advance!

25Q64FW is bios chipset, 1.8V, you have to desolder it to read it.
