+**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:
+
+* # 2
ABC 8
TUV 8
TUV 6
MNO # ("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).
+
+
+* # * # 2
ABC 6
MNO 3
DEF 7
PQRS 6
MNO 4
GHI 3
DEF # * # * ("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.

+Variants and update situation
+=============================
+
+The KEYone is sold as different models: BBB100-1 (US model), BBB100-2 (EMEA model), etc. And each
+model is distributed in multiple variants, expressed in the last 3 digits of the PRD number.
+
+Here are a few models and variants:
+
+| Model | PRD number | Variant |
+|------------|---------------|:-----------------------|
+| BBB100-1 | PRD-63116-001 | Unlocked US |
+| BBB100-1 | PRD-63116-003 | Bell |
+| BBB100-1 | PRD-63116-005 | Rogers |
+| BBB100-1 | PRD-63116-036 | AT&T |
+| BBB100-2 | PRD-63117-003 | Unlocked UK |
+| BBB100-2 | PRD-63117-011 | Unlocked Germany |
+| BBB100-2 | PRD-63117-015 | NL, Belgium |
+| BBB100-2 | PRD-63117-023 | AZERTY Belgium |
+| BBB100-2 | PRD-63117-027 | Unlocked UAE |
+| BBB100-3 | PRD-63118-001 | Unlocked |
+| BBB100-4/5 | PRD-63734-001 | Unlocked |
+| BBB100-4/5 | PRD-63734-002 | Unlocked? |
+| BBB100-6 | PRD-63763-001 | Unlocked |
+| BBB100-7 | PRD-63764-001 | Unlocked |
+
+While the variants of a model all have the same hardware, the different variants allow for
+different features being enabled, e.g. for different carriers.
+
+The downside is that different carriers also release updates at different times. Sometimes weeks to
+months after other variants got them already. Luckily, all different variants of a model seem to
+use the same firmware. This allows to install updates from another variant should they not be
+available for the own device.
+
+
+Update process in general
+=========================
+
+On the KEYone, there's an app called *Updates* pre-installed which sends the device's PRD number
+and current firmware version to TCL's servers which then reply with "There's no update for you." or
+the link to the update file.
+
+The app then downloads said file and puts it at the right location so the Android bootloader can
+find and install it.
+
+Such OTA update contains a script with all instructions about what is to be updated. This script
+also does various checks first to make sure it can be installed properly. So the risk using the
+method described below is very small as a wrong update would abort automatically.
+
+
+Enabling advanced mode in Updates app
+=====================================
+
+The *Updates* app on the KEYone has a hidden advanced mode with additional features. You can
+activate that by tapping the three dots in the upper right and selecting *Help* to get to the
+help screen. There, tap 8 times on the last item *Checking for updates*. A dialog box will appear
+asking you for a password.
+
+The password can be obtained by decompiling the APK file for the Updates app, either using some
+[online service](http://www.javadecompilers.com/apk) or [an app](https://play.google.com/store/apps/details?id=com.njlabs.showjava)
+and looking at the `/com/tcl/ota/AdvancedModeValidateFragment.java` file.
+
+
+
+After you've entered the correct password, three new menu items appear in the Updater's main menu:
+*Update manually*, *FOTA test* and *Project test*.
+
+
+Menu item: Update manually
+--------------------------
+
+This one allows you to install a full firmware update manually from the device. You need to name
+the update file something like `JSU_PRD-63117-123.zip` (replace the PRD number with that of your
+device) and put it in the root directory of your MicroSD card or the internal storage.
+
+It should then appear in this menu in the *Updates* app. You can install it by tapping the three
+dots behind the filename and select *Install*.
+
+
+Menu item: FOTA test
+--------------------
+
+Here you can simulate different phone models/variants with different firmware versions and test
+if the updater works correctly. **This is exactly what we need during the process below.**
+
+
+Menu item: Project test
+-----------------------
+
+This menu item shows a few parameters like your PRD number (called *Device CU Reference* here),
+current firmware version, your IMEI and a few more parameters. You can also test the notification
+Spark in the BlackBerry Launcher and the Play Services.
+
+
+Finding out which variant gets what update
+==========================================
+
+OTAs are always differential updates for a specific firmware version to a newer one. To install it,
+you **must** have the correct initial firmware installed. Otherwise, the updater script will fail
+and abort the update.
+
+To find out which updates are available for which variant, I found [this script](https://gist.github.com/thurask/f4ace564e6575ef41c4e35d2458ca2d0)
+which I rewrote and improved. My version can be found here:
+
+
+
+After downloading or cloning the repository, edit the `tclcheck_all.py` and change the `fc.fv`
+variable to your current firmware version. Let's assume you have a UK BBB100-2, so your PRD would
+be `PRD-63117-003` and as of September 2017, your firmware version would be `AAM481`. So change the
+line with `fc.fv` to:
+
+ fc.fv = "AAM481"
+
+Also change the `fc.mode` line to:
+
+ fc.mode = fc.MODE_OTA
+
+Now run the script. You'll get an output like this:
+
+~~~
+List of latest OTA (from AAM481) firmware by PRD:
+...
+PRD-63117-003 failed. (No update available.)
+PRD-63117-011: AAM481 ⇨ AAN358 d819919187b46793abeaeff60dd6deee17baac4b (QWERTZ BBB100-2 (Germany))

+PRD-63117-704 failed. (No data for requested CUREF/FV combination.)
+PRD-63117-717 failed. (No data for requested CUREF/FV combination.)
+...
+~~~
+
+As you can see, our `PRD-63117-003` variant doesn't have the update yet, but other variants have.
+Just pick one, let's say `PRD-63117-011`.
+
+
+Doing the actual update
+=======================
+
+Now that we've chosen a variant that has the update we want, we just have to make the updater
+think our device is that variant.
+
+To do this, go into the new menu *FOTA test* and there:
+
+1. enable **Test mode**
+1. set the *Emulated CU Reference* to the chosen variant: `PRD-63117-011`
+1. set the *Emulated current version* to your current version: `AAM481`
+1. tap the START TEST button below
+
+You should end up back in the updater's start screen. Tap the **CHECK FOR UPDATES NOW** button.
+It should search for updates and find the OTA to version `AAN358`. It should also start to download
+the new version. When done, tap the button to start the installation.
+
+Your phone will reboot and install the update. It'll boot up to the new version.
+
+
+In the case of the `PRD-63117-003` variant and assuming a time of mid-September 2017, the just
+installed `AAN358` isn't the latest version. There's a newer `AAO472` version available. So change
+the `fc.fv` line in the `tclcheck_all.py` to `AAN358` and run it again. You'll find out that only
+the variant `PRD-63117-034` is currently getting the OTA update to `AAO472`. Enter that into the
+*Emulated CU Reference* field in the *Updates* app, change the *Emulated current version* to the
+just installed `AAN358` and tap START TEST again. It'll show the second update and let you
+install that.
+
+(If the updater started to download the previous update file again, remove it like explained in
+the *Cleanup* section.)
+
+
+
+Cleanup
+=======
+
+Disabling test mode
+-------------------
+
+After you've updated your device, it's important to disable the **Test mode** of the *Updates* app
+so it will notify you of further updates. To do this, go into the *FOTA test* menu and slide the
+switch for *Test mode* into the "off" position.
+
+
+Removing already downloaded update
+----------------------------------
+
+It might happen that the updater starts to download the same update (which we just installed)
+again. If that happens to you, first make sure the **Test mode** is disabled (see above), then go
+into the updater's *Settings* menu. You should find an entry about the downloaded file with a
+dustbin/trashcan icon. Tap that to delete the wrong file.
+
+
+Disabling advanced mode
+-----------------------
+
+There's no built-in way to disable the advanced mode of the *Updates* app. So the only way is to
+reset all settings for the app itself. To do this, you need to go into the Android settings →
+*Apps*. There, tap the three dots menu and select *Show system*. Now scroll down the list to tap
+the *Updates* app. There, tap *Storage* and hit the CLEAR DATA button. After that, the
+*Updates* app is in "Basic" mode again.
