**USE THESE AT YOUR OWN RISK!** Especially the Engineering Mode has a few options which can trigger

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")
|
||||||
|
|
||||||
|
|
||||||
|
<p><div class="noteimportant" markdown="1">
|
||||||
|
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.
|
||||||
|
|
||||||
|
<!-- Password: fotaapp*#1221# -->
|
||||||
|
|
||||||
|
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:
|
||||||
|
|
||||||
|
<https://github.com/mbirth/tcl_ota_check>
|
||||||
|
|
||||||
|
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:
|
||||||

~~~
|
||||||
|
|
||||||
|
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 <kbd>START TEST</kbd> 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.
|
||||||
|
|
||||||
|
<p><div class="notetip" markdown="1">
|
||||||
|
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 <kbd>START TEST</kbd> 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 <kbd>CLEAR DATA</kbd> button. After that, the
|
||||||
|
*Updates* app is in "Basic" mode again.
