Intenta ##3282# o sino ##3282 y aprieta Call para Field Test y ademas vea
estos otros. Me parece puede ese Lumia ante Dual Carrier es que muestre 4G
pero en HSPA+ normal sólo di de H+ seguramente.. Enjoy it and Bon Voyage !!!
MUCHO CUUDADO NO CAMBIAR NADA
##634# - Color Variant + Call Life Time Counter (L920, L928)
##4678255# - Tier3 Status (L920, L928)
*#07# or ##07# - Launch main page of extras+info
##778# - Product Support Tool
##3282# or ##3282w/call - Field Test (L521, L820, L920, L925)
##777# or ##777w/call - User Content Reset(tested on 1520 w/059V276 PROD code)
##7820# or ##7820w/call - SIM Lock Status
Nokia Lumia 525 (RM-998_apac_malaysia_935)
Works from the dialer:
##634# - Shows color variant and lifetime counter.
##07# - Opens extras+info and gives a page that says "Lumia Black" and
lists the model and type followed by some logos of standards.
##4678255# - Shows Tier3 status, which I honestly can't make heads or tails
out of beyond a list of apps and guids.
Needs native toast launcher:
##778# - Opens service tools, but nothing seems to be doable there. It says
"select function set" but there's nothing to select.
##3282# - Opens field test. Tried locking network to 3G on one of the
networks here that have bad reception, and that works perfectly.
##7820# - Shows sim lock status. Now this is where it gets weird. This is
an unlocked phone bought in Malaysia and currently used in Sri Lanka on a
Sri Lankan network (only the SIM card was given by the service provider).
It's working perfectly, yet this claims that the phone is sim locked (shows
a lock over a SIM card icon) and gives me a text box to enter a key which I
don't have nor can ever obtain, since the phone wasn't purchased from a
service provider.

Please note there was not a "4G" listed. As for specifically the 920, I've
read ##3282 not ##3282# works following some sort of update not too long ago.

##3282# does in fact work.

Test Mode or within Settings.

times, it shows as unlocked.

NOTE: Most of the dial codes for the Lumia 928 is @cpuguy's work. I merely
adjusted it about my device instead.
Color Variant + Life Time Counter
Code:
Code: ##MFG# (##634#)
Description: Also not new... Displays the multivariant color (my value is
null but yours might be displayed) and life timer. It reads that info from
the registry ("Software\OEM\Nokia\Multivariant\Color" and
"Software\OEM\Nokia\lifetimecounter"). It also displays the modem version now.
Component: ColorVariant.dll

Silent Installer Component - aka Tier 3 (Launches a screen titled Tier3
Status and displays several OEM installed apps)
[CODE]Code: ##4678255#[/code}
Description: [The Lumia 920 from another thread] does nothing at this time
but the code seems to indicate that it monitors for provxml files. The
monitoring is actually done by the SilentInstallerServiceAgent
(SilentInstallerServiceAgent.dll). It monitors for registry entries
pointing to physical provxml files at
"SOFTWARE\OEM\Nokia\SIAgent\Multivariant" and
"SOFTWARE\OEM\Nokia\SIAgent\Tier3". It also monitors the physical folder
"C:\Programs\CommonFiles\OEM\Public\PreloadedApps\ tier3Apps". When new
provxml files are detected, it executes them (I haven't seen any indication
so far that it'll do anything besides file copy instructions).
Component: SilentInstallerComponent.dll

extras+info (launches the same page from settings)
Code:
Code: *#07# or ##07#
Description: The code is purposely written to keep all elements on the main
page to a "Collapse" visibility (meaning hidden). All the information would
be normally displayed when launching the "extras+info" application is in
fact populated.
Component: Regulatory.dll
Product Support Tool (no actual title)
Code:
Code: ##PST# (##778#)
(can possibly be launched through an NFC tag if specifying a "DialString"
argument with a of value "778" - untested)
Description: Has the same function on various WP7 devices; allows access to
cell network settings. Uses a pass code of 000000. No fields are editable.
Component: ProductSupportTool.dll

The following URL has multiple devices that has the app installed. To use

Nokia developer account. [NOTE: Its recommended you attach your developer

EDIT 2: There isn't much info about on the ODDT from Nokia. I've uploaded
and embedded the videos demonstrating the oem diagnostic tool and some
other stuff I did in the session.
