Chromebooks are laptops that assist users in web browsing. If the Chromebook has secure hardware, the user can take benefits beyond the official expiration date of Chromebook. But in case, you are getting regular warnings that say “This device is no longer supported,” then you need to update Chromebook.
Before proceeding, check if your Chromebook is included in either of the “FULL ROM firmware” columns on the supported devices page for the Mr. Chromebox script. In case your device only has a checkbox for RW Legacy, then don’t follow this procedure.
One more thing, you can quickly return to the regular Chrome OS setup. You only have to Follow Chromebook, boot into recovery mode then run the recovery stick. This can be done even after the developer mode is enabled.
Methods to update Chromebook
Below we have discussed some simple steps to update Chromebook.
Step 1. Backing up data and making a Cloud Ready Installer
Go to your Downloads folder and check the stored data. Transfer the things you want to save to either Google Drive or onto a USB drive. The Chromebook’s storage has to be wiped out twice. Before wiping the Chromebook, you may also use it to create the USB stick for installing Cloud Ready Home Edition. A Windows or Mac computer can also be used. Now Download the suitable file from Never ware and follow the instructions to make a USB stick into an installer. Try a different USB stick if it doesn’t work
Step 2. Remove the Write protection of Chromebook
Chromebooks have a screw-on their mainboard that is connected to metal pieces. It completes the circuit which protects the inner parts of the firmware. To open up the storage for writing Cloud Ready onto the device, this screw has to be removed.
Step 3. Enabling the recovery mode and developer mode
After disabling the write-protect, the first thing you have to do is to boot the device into Recovery Mode. Hold down the Esc and Refresh keys. Now hold down the power button till the device powers off or press the power key until the device turns on. You will get a message, “Chrome OS is missing or damaged,” or “Please insert a recovery USB stick or SD card.” If you can see this message, then hold the Ctrl key and press “D” button.
When you get the notification asking if you want to disable OS verification, press Enter, this will wipe the Chromebook, and the device will get reboot once or twice. Now you will be able to see a screen saying, “OS verification is OFF, press SPACE to re-enable.”
Again, hold Ctrl key and press “D” button. you will get the same screen that appeared on the first set up of Chromebook.
Step 4. Install a new BIOS
Click any button on the setup screens. Select your Wi-Fi and enter your password. Hold down Ctrl and Alt and press the second key, which is at the right of the Esc key. (it may be forward or refresh arrow). A stark looking terminal will appear now. Type command “cd; curl -LO https:// Mr chromebox.tech/firmware-util.sh && sudo bash firmware-util.sh” to install a new BIOS on Chromebook.
Once you run the command, you will get a menu having options of CPU, firmware type, write protection is enabled or not. If you find that the write protection is enabled then check what you have done wrong. Otherwise, choose the Install /Update Full ROM Firmware option.
Step 5. Install Cloud Ready
After completing the above steps, plug the Cloud Ready USB stick into the Chromebook. Once you see a running bunny on your new boot-up screen, press Esc key. Tap the Down key on the BIOS screen until you end up at Device Manager. Press Enter. When the list of devices comes up, select whatever looks like your USB key.
