How to Hack your Blackberry (Access Engineering Screen)

Sorry if I'm being dense about it LoL

No no, you're fine; I see what you're after now. Unfortunately, if you alter anything in the engineering settings they will not be backed up or restored with a device backup. You're basically in what corresponds with the BIOS settings on a computer.

That's a fairly accurate explanation.

Some (not all) engineering screen settings are stored in the BB memory in a location separate from the data that is backed up and restored (possibly another partition? I don't know. App settings are the same. My theory is that RIM doesn't let these be backed up to help maintain their security, which is in a large part due to the inability to access the lowest levels of the device). Some get wiped out with an OS reload, and some get wiped out with as little as a battery pull. Nonetheless, treat EVERY setting as if it could be permanent, because it could be.

Escreens are accessible on 6.0.0.666, and on 6.0.0.668. I have never had any problem accessing the escreen.

Is there a way to turn off the engineering screen and go back to the old screen when you press alt-shift-h ? I enabled the Engineering screen when I had to find out the MEP and now I cant seem to be able to go back!

Thanks!

Nope, it'll time out once that happens. Usually within 24-48 hours.

I believe you can move your berries date forward a few days and then back again to switch it off.

Thanks guys! Yes, both of you were right - after 24 hours or s it was gone automatically :-)
Cheers!

Hi everyone, I have been using escreen to lock my service provider's 2G channel in my 9700, however, i couldn't do that in 9900, the whole layout of the escreen has been changed, its different

before was "mobile network engineering screens" > PLMN selection

then i could play around a bit over there, now i couldnt do anything with 9900

does anyone know?

Go to radio enginerring screen(3GPP) then 3GPP radio enginerring screen then select Operational Info, scroll down and you would see the PLMN selection, hope I was of help

thanks for your reply,

But the PLMN selection cannot choose the channel
before I could use the PLMN selection to lock in "Roaming" Channel, now I couldnt

[johnnytam]

I meant there was a "Network List Follows"

505:03F (2G)
505:01F (2G)

then I could select, 9900 seems without this function?
or hiding somewhere?
