Chromebox: developer mode chromebox

I recently bought a HP chromebox to use a kiosk application. However, to completely install the kiosk application in the way I need to, I need to switch to developer mode.  In accordance with the instructions that I have to

To call the developer/restore mode, you insert a paperclip and press the RESET BUTTON (just beside the kensington lock) and press the power button. Release the RESET BUTTON after a second.

Mode Dev first call you the recovery and to the recovery screen, press Ctrl-D (there is no prompt - must be made). It will ask you to confirm by pressing the reset BUTTON again.

Dev-mode works as always: it will show the scary start screen and press Ctrl-D or wait 30 seconds for initialization.

However, when I do this the box does not send any video signal to my HDMI screen so I am completely in the dark as to what is happening, if anything. I tried with a wired USB keyboard and a USB wireless keyboard, same result: nothing seems to happen.

Who has an idea to switch to developer mode on thisHP chromebox? (Not a chromebook)


Hi @StephanvR,

Steps performed by you to switch to Dev Mode seems to be OK.

As you mentioned that you have connected the display via HDMI and there is no display.

Therefore, you can try to connect to display Port (DP) and check if there are any screen.

I hope that answers your question.

  • Not able to run standalone LabVIEW RT application cRIO (works well in development mode)

    Strange question.

    I'm trying to deploy an application of RT to a controller for cRIO-9074.  I developed the application in development mode and everything works and seems to be being debugged.  However, when I try to build and to deploy the application as the startup, the application seems to start running, then stop cold (based on the CPU usage as described in the Distribution System Manager OR).  At this point, I can't debug because the application is stopped (no updated variable).

    The problem seems to be related to the NI_AALPro.lvlib library, because if I turn off the function polynomial evaluation, the code will compile and start fine.  I'm tempted to recreate the necessary functions and create my own library, but I prefer to find the problem and fix it rather than re-create the wheel...

    Is it possible that the library badly uploaded to the controller?  If so, is it possible to force the appropriate library to be transferred to the controller?

    Thanks for any help.


    Thanks for the reply.

    I think I solved the problem.  For some strange reason, the functions inside the NI_AALPro.lvlib were not available on the cRIO at run time when the application tried to run in stand-alone mode.  I ended up adding the library to the section to always include the source files tab in build specification and the program runs now.  I'm not sure what it is, but it works.

    Thank you Morgan of NOR.

    The 169.254 is for the USB interface, but you can set one or the other as the debug ip in the properties of the device.

  • Z10 blackBerry development mode


    When I go into Settings/Security/Development mode, I can:

    • activate this,
    • specify an IP address for the development,
    • install a token "debug".

    (if I translate well to the french).

    Could someone tell me more about these options?

    Is there a security problem if I try and install the debugging token?

    The token lets connect you the phone via ssh (among a few other things.)  You don't always have root access on the same phone with installed.

    With mode on you can sideload apps debugging, but they must always be signed (by someone with a BlackBerry Developer certificate, which could be you.)  Without development mode on the phone will not allow direct loading of applications via the interface USB at all.

    For purposes of sldeloading, there is no need to install the debugging token.

    Hello BojanKogoj,

    Thank you for your question. There is unfortunately no way to support to have your device in development mode without having a defined password.

  • Developer Mode error: outdated., the xxAM.xxVO1 view object contained no trace. The records displayed may have been deleted, or the current record of the view object is not properly initialized.

    Hi all

    I'm creating a Maunal search page.

    To do this, I created a view based on a custom display object.

    Page contains 2 parameters.

    If I give all settings and click the OK button.

    It gives the following error.

    Developer Mode error: outdated data

    This page contains outdated information. This error could have been caused by the use of the buttons of the browser (the browser back button, for example). If the browser navigation buttons were not used, this error may result from coding errors in the application code. Please check press the back button on the browser developer guide - view primary key object comparison section to review the main cause of this error and correct the mistakes of coding.

    The view BLTrinDisplayAM.ViewVO1 object did not contain any record. The records displayed may have been deleted, or the current record of the view object is not properly initialized.

    To visit, please click on the Home link at the top of the application page to return to the main menu. Next, go to this page using the app's navigation controls (menu, links and so on) rather than use the controls of the browser as rear or front.

    If I don't give any parameter and click go Button.The content of the view are displayed.

    So if I pass all parameters and click Go, then the corresponding record is displayed.

    Why, for the first time, if I give the parameter and click Go, obsolete data error is coming?

    Please help me.

    Grateful for your help!


    You use the object of the view for the search criteria and search results fields.

    I suggest you to remove references of VO fields of search criteria, item1 and item2.

    And in the event of the button 'Go' in the processFormRequest, get the criteria for field values entered by the user as below and run the object (ViewVO1) of the view by using these values.

    String buCode = pageContext.getParameter ("item1");

    String lsiCode = pageContext.getParameter ("item2");

    Thank you

  • My pictures as soon as I switch to 'develop' mode completely to chance

    I'm fairly new to Lightroom and I would love to work with her, but I have no idea of what is happening to my photos. I've seen a lot of tutorials and find out how to import a picture and what I can do with the mode of development. But as soon as I import one of my photos (JPEG format) and go to "develop" - mode, my picture is kind of screwed upward and I don't know what to do. I tried it with pictures of external hard drives, as well as with the photos on my laptop. Also, I closed and restarted my laptop, but it's always the same.

    It does not void the warranty. I have my pre in this mode as well. Basically make it so you can install beta apps that you create or if you test a developer it allows to install it and test it.

    Also if you do a partial erase on the device it removes it developer mode if this is the cause of any technical problems you may have with the device. More so, just like you got the unit out of the box.
