**USE THESE AT YOUR OWN RISK!** Especially the Engineering Mode has a few options which can trigger
|
|
|
|
|
DTEK (showing your OS as compromised) and probably do worse.

(These codes seem to be standard for Alcatel phones. Interestingly, they work here, too.)

MMI Test
|
|
|
|
|
========
|
|
|
|
|
|
|
|
|
|
This is similar to the BBVE and provides various tests for all phone components. To open it, open
|
|
|
|
|
your phone dialer and type this:
|
|
|
|
|
|
|
|
|
|
<kbd>*</kbd> <kbd>#</kbd> <kbd>2<br/>ABC</kbd> <kbd>8<br/>TUV</kbd> <kbd>8<br/>TUV</kbd> <kbd>6<br/>MNO</kbd> <kbd>#</kbd> ("AUTO")
|
|
|
|
|
|
|
|
|
|
To test single components or get traceability information (PRD number, manufacturing date, etc.),
|
|
|
|
|
tap "MANU". The buttons "AUTO1" and "AUTO2" run several tests automatically. To exit the test mode,
|
|
|
|
|
tap "MANU" and find the "Exit" option at the end of the list.
|
|

Engineering Mode
|
|
|
|
|
================
|
|
|
|
|
|
|
|
|
|
This mode has a few settings (black font on black background - hold your finger above where the
|
|
|
|
|
text should be for the background to become grey, making the text visible).
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
<kbd>*</kbd> <kbd>#</kbd> <kbd>*</kbd> <kbd>#</kbd> <kbd>2<br/>ABC</kbd> <kbd>6<br/>MNO</kbd> <kbd>3<br/>DEF</kbd> <kbd>7<br/>PQRS</kbd> <kbd>6<br/>MNO</kbd> <kbd>4<br/>GHI</kbd> <kbd>3<br/>DEF</kbd> <kbd>#</kbd> <kbd>*</kbd> <kbd>#</kbd> <kbd>*</kbd> ("ANDROID")
|

After enabling "root", some apps might be able to modify system settings and thus making DTEK show
|
|
|
|
|
the system as "compromised". The only way to reset this is to do a factory reset.
