U-Wipe 2.5 serial key or number

Activation Lock is a feature that was introduced to iPad and iPhone as a part of iOS 7 and computers as of macOS , which protects devices by linking a user's personal Apple ID to a device. If a device is ever wiped or restored, the user's Apple ID and password are required to unlock the device.

When an organization deploys supervised devices with Jamf Now this Activation Lock feature can be bypassed. That means that if an employee leaves without removing their Apple ID that locked the device, Jamf Now can provide a code to unlock the device, which will allow your organization to set it up as new.

Bypassing Activation Lock on a Mac, iPad, or iPhone requires the device to be supervised with either Automated Device Enrollment or Apple Configurator (iOS/iPadOS only).

Important: If you remove the device from Jamf Now after being wiped, you can no longer bypass Activation Lock.

1. Log in to Jamf Now.
2. Click on Devices.
3. Click on the device for which you need to bypass the activation lock.
4. Click the Action pop-up menu (•••) in the top-right corner of the page, and then select "Show bypass code" from the pop-up menu. 
5. Use this bypass code in place of the password for the locked device. Leave the Apple ID field blank.

This release was created for you, eager to use U-Wipe full and without limitations. Our intentions are not to harm U-Wipe software company but to give the possibility to those who can not pay for any piece of software out there. This should be your intention too, as a user, to fully evaluate U-Wipe without restrictions and then decide.

If you are keeping the software and want to use it longer than its trial time, we strongly encourage you purchasing the license key from U-Wipe official website. Our releases are to prove that we can! Nothing can stop us, we keep fighting for freedom despite all the difficulties we face each day.

Last but not less important is your own contribution to our cause. You should consider to submit your own serial numbers or share other files with the community just as someone else helped you with U-Wipe serial number. Sharing is caring and that is the only way to keep our scene, our community alive.

From OLPC

• A developer key is a file named manicapital.com containing cryptographic information tied to a specific XO laptop that can be used to disable various security features.

• An activation key or activation is a file named manicapital.com containing a cryptographic signature tied to a specific XO laptop and provides the ability for the system to run up until a set date and time.

• The activation system is part of the security system. Therefore, when the security system is disabled (with a developer key), activations become irrelevant: they are not needed for system operation.

• Laptops can have the security system active but also be preactivated meaning that they will never request or use an activation, even though the rest of the features of the security system remain active.

Is your laptop secured?

• Give One, Get One and Give One, Get One customers received laptops with the security system fully enabled, but the laptops are also preactivated meaning that they do not require an activation. Developer keys are required for some operations.
• If your laptop is part of a deployment, the choice of security, security + preactivation, or no security is defined by the deployment. When buying laptops from OLPC, the customer specifies their choice and the laptops are programmed accordingly at the factory (you may be able to determine this from the Manufacturing data page). In some cases, this choice is then changed manually by the customer after the laptops have been received.

What the security system does

• Unless the laptop is preactivated, the system will only boot while it has a valid and non-expired activation.
• The only operating systems images that can be installed are those that are signed by a trusted party (which can be OLPC, the deployment, etc, based on the laptop's configuration at the factory).
• The only firmware releases that can be installed are those that are signed by a trusted party.
• The only kernels and initramfs (boot code) that can be booted are those that are signed by a trusted party.
• You cannot gain access to Open Firmware's ok prompt.

A developer key will disable all of these functions, providing no restrictions on what code can be ran and whether the laptop can or can't be used.

Why you might want to unsecure your XO

OLPC and others produce unsigned operating system images for development and testing. These will only work on unsecured laptops.

Various repair procedures, such as reprogramming the clock require the security system to be disabled (perhaps only temporarily).

When "secured" laptops can be useful

This security is part of the Bitfrost security system, and is used to ensure that unless the user has specifically opted out, their basic operating software remains unmodified, and provides various antitheft controls. Many OLPC customers express that security and antitheft systems are of high priority.

How to tell if your laptop is secured

secured; coloured icons, and no "ok" prompt

• Shutdown the laptop,
• Hold down the '✓' (check) game pad key and turn on the laptop,
• Wait for the message Release the game keys to continue,
• Hold down the Escape key (the top left key on the laptop keyboard, marked with or "esc"),
• Release the '✓' (check) game pad key, and watch closely.

If a message Secured, continuing appears, or three coloured icons, the laptop is secured.

If the laptop boots the operating system, the laptop is secured.

secured, but unlocked; an unlock icon, and an "ok" prompt

If a message Devel key Signature valid appears, and an icon corresponding to the device the developer key is on, then the laptop is secured, but unlocked by the developer key.

In this situation, you can disable security.

not secured, the "ok" prompt is present

If an "ok" prompt appears straight away like this, the laptop is not secured.

In this situation, you do not need a developer key.

Getting a developer key

To get a developer key you will:

• get two numbers from the laptop, the serial number and the UUID,
• send these numbers to us,
• wait for up to 24 hours,
• receive the response.

We provide several ways to do this, as subsections below:

Getting a developer key using a USB drive

A collection stick is a special USB drive that collects data so that you can request a developer key. See collection stick for how to prepare a USB drive and use it.

Getting a developer key for your running XO laptop

There's a "Developer key request" web page on the XO to apply for a key.

1. On your XO, open a new Browse activity, and navigate to the request page:
   • For release , x, and later, click on the link "get a developer key" at the bottom of the Browse start page,
   • otherwise, type file:///home/manicapital.com in the browse location field and press enter.
2. Follow the directions to apply for a developer key; it should be created in a day or two.
3. Go back to the request page when your key is ready, and follow the instructions to download your key to your XO.
   • Once your key has been created, you can return to this page at any time on your XO to re-download it; there will be no further creation delay.
4. Reboot your XO.

Next, using a developer key.

Tip: if the typeface is too difficult to read easily, you can use Browse's Zoom options (in the View menu) to make it larger. Alternatively, you can copy the text and paste it into the Write activity, where you can resize it.

How to get a developer key when Browse freezes

At times Browse can freeze when trying to activate your key. An alternative way of activating is by starting Terminal or by pressing Ctrl+Alt+ to get to a console and get the serial + uuid for activation. Once you see the terminal, you may need to type in "root" with no password to login.

Next type in:

on line 16, there should be the serial_num (write down what it says under VALUE="") and what it says on line 17 the uuid VALUE=". You will need this information to register for your key.

Next, on a computer that has web access and click on: manicapital.com and enter in the serial and uuid that you got from the manicapital.com file and click on "Request developer key".

You should then return to the web page after 24 hours. Your key will be ready for you.

Getting a developer key without WiFi

If you have wired network access, you can:

Getting a developer key without any network access

• copy the file /home/manicapital.com from the XO to another (network-connected) machine, and perform the process from that machine. Entering the following command in the Terminal activity will copy it to any USB devices connected:

Getting a developer key by postal mail

You can write postal mail to OLPC, see the addresses on the contact page.

You must include your serial number, a return address, and that you are asking for a developer key.

Your developer key will be mailed back to you on paper. You will have to type it in to a manicapital.com file. This is prone to error, so try hard to use other methods.

Next, using a developer key.

Using a developer key

Our response will be a small file manicapital.com containing a large number. When you give this file to the laptop in the right way, it will be temporarily unlocked.

Make back up copies!

However you get a key, please make a copy of it on some other computer, one that gets backed up regularly, in case this one is lost. Also, you should copy your developer key to on a USB drive, if you have one.

Where the developer key can be placed

When the XO boots, its firmware checks to see if security is enabled or permanently disabled (a system parameter). If it is enabled, it looks for the a developer key, at , on any USB flash drive or SD card that's plugged in, and on the internal storage. (See Firmware security for the details.)

If that file is there and contains the right number, the XO will act as though it is unsecured:

• You will be able to interrupt the boot process and enter commands,
• You can run any compatible operating system, not only the signed operating system,
• You will be able to disable the security permanently.

Disabling the security system

Once you have a developer key:

• Make sure it is in the directory on your USB drive or SD card.
• Plug it into your XO before booting it. Boot your XO with that drive/card plugged in.
• You can now either immediately install unsigned software, or interact with the firmware -- including permanently disabling the firmware security system. (Once this is turned off, you will no longer need your XO's developer key to run the machine in "unsecured" mode.)

To permanently turn off firmware security:

• Boot the XO as above, with a USB drive or SD card with the developer key plugged in. Interrupt the boot sequence: press the Escape key a few times during the startup sound, just after turning the laptop on, to bring up the firmware Ok prompt. (for other ways to reach the prompt, see Ok prompt.)
• Type . Press enter.

1. If disable-security says "No wp tag", it means that security is already disabled.

2. If disable-security says "Restarting to enable SPI flash writing. Try again after the system restarts.", you'll need to start over with the Esc key again as above.

• When security is disabled, you can re-enable it for a single boot (say, to test how a secured machine would work) by pressing the X gamepad key while powering on. This is useful to do firmware upgrades from signed builds. It can also help to test secure boot on release candidates.
• You can reverse the disable-security command by entering enable-security at the 'ok' prompt. Security will then be permanently enabled until disabled again.
• You can see the raw manufacturing data where the disable-security setting is stored by typing ".mfg-data". See Manufacturing data for details.

Troubleshooting disabling of the security system

Some have had some issues with disabling the security when the developer key is on a USB drive. This may happen if the USB drive is incompatible with the firmware. If you experience this problem, try upgrading firmware, or try using an SD card instead. It should be vfat formatted, for which you can use gparted.

Then stick the SD into the XO (it is under the screen, you need to turn it -- it is on the right side), reboot and hold down -- then you will get to an ok prompt type:

it will automatically reboot to enable access to internal data, and you must repeat this step, then it will update the internal data and reboot again.

Now you can reboot and take out the SD card if you hit it will bring you to the {ok} prompt

If you wipe out your developer key

If you reflash your XO you will remove . One way this can happen is if you ever do a fresh install of an operating system image using the clean-install procedure (rather than olpc-update). If you haven't disabled security and the OS image that overwrote flash is unsigned, then your laptop won't boot. But you have several options:

• Ask us for the developer key again, and there won't be a 24 hour delay.
• Revert to a previous OS image. Try pressing the 'O' (circle) gamepad key while booting. That will attempt to boot a previous version of the OS, and if it was signed it will succeed.
• Reflash again with a signed OS image.
• Insert a USB drive or SD card with your developer key on it in (this is why you should always be sure to backup ), which will allow booting of the unsigned OS image and/or let you get to the 'ok' prompt to disable security.

Once boot completes you can restore your developer key back to NAND flash by typing in a terminal something like

or you can re-visit the "Developer key request" form and re-download your developer key. But you would be better off if you immediately disabled security, as described above; that never expires, unlike developer keys in NAND flash that often get overwritten.
