seriously, RTFM.

I don’t know why you’d come here for help, and not check the docs to see how WP is implemented for your device. It’s not a screw or the battery, obviously.

ive looked everywhere and cannot find a manual that shows how write protect is enabled

what does my site and the docs here say?

I had the same issue, I’d disabled software wp, found the pads to jump to bypass and never got it. I would suggest buying a probe and just flash the physical chip. It’s kind of tedious, but following their writeup got me there. If you haven’t figured it out yet, dont give up. Its an awesome platform once its sorted out. I have win 11 on my cm34, daily driven it since December and i absolutely love it.

IMO, there’s no need for that, a SuzyQ is better and more flexible. Flashing directly still requires disabling RO verification manually.

I couldn’t find any available, so made my own and couldn’t get it to work, but i also think mine just didn’t like me lol

they’re $10 on ebay :slight_smile:

Well now i just feel stupid :upside_down_face:

For me on Asus C425 TA, I unplugged the battery connection and did plug in the power cord while restarting the ChromeOS (without the battery connection). Next, I got to the command prompt via Ctrl+Alt+F2 and re-flashing the updated firmware using the scripts from MrChromebox. Everything went smoothly. The script offered a backup of ChromeOS firmware on a USB.

Once, the new UEFI firmware update from MrChromebox was complete, I, then, reconnect the battery connection. You can now install a Linux of your choice.

the C425CA is a completely different device from the CM3405

Thank you MrChromebox for the clarification.

It was my mistake in bringing up the CR50 method as the Frostflow (Asus CM34 Flip) used Ti50 as a verification method.
