    Default How to Hack your Blackberry (Access Engineering Screen)

    Want to know how to hack your blackberry? Look no further, follow this link and have fun!

    How to: Hack your Blackberry | GizmoFusion



    PROCEED WITH CAUTION THIS CAN DAMAGE YOUR BLACKBERRY BEYOND REPAIR!


    So our member's don't have to go anywhere to see the blog I have copied it here, BUT I have left the link and full credit of course goes to GizmoFusion. -pk ......


    Being a nerd, I am always looking for ways to crack into things and access an additional layer of functionality. This led me to research where come to find out, there is a way to accomplish this on the Blackberry platform.



    First off, I have to be honest, I am by no means an expert at hacking Blackberries, and any setting you decide to monkey around with after I tell you how, please do at your own discretion. It is completely plausible that if you tweak or change the wrong setting you could end up with a pretty paper weight.

    Now that my disclaimer is out of the way, lets get to it, shall we?

    Hidden deep beneath the Blackberry OS is the Engineering Screen or the E-Screen. This is the place where the engineers hang out, fly kites and take walks on the beach. RIM knows that if this menu was readily accessible, people would start bricking phones left and right, so as it stands, there are a couple of steps you need to complete to access the E-Screen.

    Ready? I thought so…

    1.First things first, you need to access the “Help Me” screen. Press Alt+Shift+H from the home screen. Welcome to the “Help Me” screen, this is a cover up for the engineering screen that is below.
    2.To access the E-Screen you need to use the information on the “Help Me” screen and input this information into a special code generator which will generate the secret code needed that is unique to your Blackberry.
    3.Use the code generator and instructions found here.
    4.Once you have access to this menu, every time you press Alt+Shift+H you should go into the E-Screen without having to use the code generator.
    5.Have fun, who knows what kind of trouble you can get into in there. Leave us a comment if you find out how to do something cool.

    Like I have said before, getting in is old news. Changing what, to what. And at what cost or benefit? Let us know if you get any parameter settings and what they improve. Otherwise it may as well be instructions for setting up a latrine written in martian.

    I have found out how to enable EVRC-B and disable the event log from filling up and slowing your blackberry down.

    The engineering screen is used to fine tune operating parameters in the prototype modes. It has access to the setting, but it has no way to roll back to normal is something goes wrong.

    Use it with extreme caution. Before you make any changes, record the defaults.

    Yep, been in there before.

    The only thing I want to change in my Pearl, but haven't actually tried, was to change the default settings for when the screen dims or brightens. Sometimes the screen dims to the next lower setting when there is still enough light around that I want the screen brighter. I then have to hold the phone higher and angle it more toward the nearest light source to force it back brighter. I haven't studied the settings and ranges enough to figure it out. But one day I will.

    For those interested in EVRC-B here is a link defining it.

    Even with the Event Log full, it does not take up much memory at all...

    Close. What I mean is, that is the way the Research in Motion engineers fine tune performance and optimize it for normal use. Changing screen brightness or other settings will likely result in more power consumption or other trade offs.

    I have used it to enable features on my own BlackBerry. My carrier supports those features, my BlackBerry does too when correctly provisioned.

    Old news, but I still keep it open because of the built-in task manager for killing unresponsive apps

    It does seem to improve voice quality, but there's a reason it's not enabled....according to this thread:

    https://supportforums.motorola.com/message/70956


    The cell tower you're on has to support the codec if it's enabled by default, otherwise you can't make any phone calls.

    There is an option in those screens to change how your phone picks up wifi so you don't get the "Blackberry Infrastructure Error" (Grey Wifi Icon when connected to BIS) but that drains the battery pretty fast. I wouldn't recommend it.

    zactly... like... RIM doesn't have any engineers smart enough to have found this screen and gone through every setting a bajillion times on multiple test beds. Maybe they couldn't find enough Blackberries to be able to really find those magic combinations that will make your phone really work like its supposed to.

    Waiting for the smoke to come out...

    Physical Blackberries nothing. I'm sure they have Computer Emulators and have tested every possible combination possible. with the push of one button.

    Just like redline on production sports cars is set actually 10% lower than reality, to protect them from lame consumers. I would imagine there are built in fail safes that if changed could improve overall performance. Hey weirder things happen all the time.

    Electronics are a little different then Engines. I am all for all things hackery. In fact i've hacked with my Blackberry ROMS ALL THE TIME. and i mess with my android OS all the time. But you are tampering with the HDD of the phone, and risking a removal of the entire bootloader system....

    like i said i'll just set back and enjoy this thread.

    I used hash codes on my other brands of phone, depending on the carrier it was similar to "#*# <some number> #", the number represented a function. It might goto an engineering screen, the phone info screen, or a reset/clear the phone screen. Didn't find anything like this on the BBs.
