So, on a whim, I tried again after a reboot, and the diagnostic app now loads just fine. Should've tried that sooner, but I figured all the rebooting during the NoDo update was enough... obviously not! :)

Trouble Accessing Diagnostic Codes

I have Diagnosis ver. 0929, which I installed using the process you explained (##634#). I tried to use some of the various codes to change some settings, but nothing happens after I enter the sequence of characters and numbers. When at the Diagnosis screen (key pad and "-" in a circle) I entered *#197328640#, expecting another screen to appear, but nothing happens. Am I supposed to do something after entering the sequence, or should a menu screen appear?
[Focus General] munkeyphyst:
You probably have a newer firmware. Not all the codes work. To get to the main menu, *#32489# and the press the back button on the screen.
[Focus General] gotvet:
I tried "*#32489 [back] and it took me to a "Test" menu screen. Am I unable to use *#197328640# to access the main menu so that I can try some of the other codes, such as "183523 [end]" to enable HSPDA/HSUPA, or is there a different method since I apparently have a newer firmware version?
[Focus General] gotvet:
Actually, I figured out how it works. Thanks for the help...

Update and question

Good afternoon all. I finally got my Nodo update and wanted to let everyone know my experience with the diagnostic tool at this point:

Get into the diagnostic tool the same way - ##634#

Test mode - *#32489# then back

When you hit back is has most of the test tools

1. Cipher Control

.

.

.

5. RRC(HSPA) mode

- you can "change" to release 5 or 6 here

6. Dulamode Improvement Center

- This is where you can turn on Dualmode improvement

Question:

Currently my "Ciphering" is turned off. Is this the correct setting or does it need to be on?

Thanks!
[Focus General] jntdroid:
So, unless I'm missing something, is it safe to say there's no way to toggle 3G/Edge through the diagnostic tools? I've read through this twice and either I'm blind (which is quite the possibility) or it's not there.
[Focus General] SuperSport:
I believe it's done using the registry. But you'd have to be unlocked for that. When I was unlocked, I changed a setting, and it gave me the option for toggle 3G inside the Network Settings.
[Focus General] munkeyphyst:
There is a diagnostic menu for turning off 3g
[Focus General] Vintage144:
This might shed some light on ciphering for you:

The data being transmitted from the BTS to the Phone and back is

enciphered. This is to prevent 'snoopers' from capturing the ID. In

the days of AMPS phones, it was aquite easy to acquire IMEI numbers

right off the air, clone them, and start making calls which are

charged to the original owner. This lead to authentication, and in

GSM, the ID details from the SIM, not being transmitted over the air.

It also prevents people from simplyh listening to cell phone

converations, as could easily be done with AMPS phones.

The ciphering is nothing to get overly excited about. I figure the NSA

could break the codes in a second or two, but it will certain

discourage the average listener from getting anywhere!
[Focus General] noid:
what is Dulamode Improvement Center? what happens if we turn on Dualmode improvement? can somebody explain?

Hi !

I've got a problem since Diagnosis use. I explain the problem in the Samsung Omnia section, but I think I will have most help here.

So this is the link wich point to the problem :

Thank you !
[Focus General] SuperSport:
Now, this is interesting to me. I too would like to hear if anyone has any info on this. I've had my SIM card & Focus replaced once, due to this issue. Messages might show up from 5 minutes to 5 days late, often getting 40+ messages all at once. And they are random. Some messages come through immediately while others don't. I went in again to repair center recently and they said it has to be a network issue and they are looking into it.

But now, I wonder if it's something I might have done in the Diag Menu. Only thing's I've ever changed on this recent phone is going from v5-6 and DualMode. Nothing else was touched. Could these possibly cause the issue reported above? Only thing I've been able to do is a soft reset, but that does not Always work. I've even tried to set those two options back, but still having random SMS issues.

PS: Sorry for double post, but I realized I was in the Omnia forum after I posted it over there.
[Focus General] siralex241:
SO I upgraded to nodo and had to hard rest. I updated my phone with official nodo release for At&t. I did ##634# and it would not download the previous version of the diagnostic program; only the new version that does not let you get to the root menu. I have a work around for the moment with the new version of the diagnostic program version (.1122)

in the new diagnostic program type *#32489# after that you can use the on screen software back button on screen three times and you are at the root menu of the diagnostic program. Maybe someone might be able to find a direct input number but for now this is to my knowledge the only way.
[Focus General] crg1970:
Can anyone please explain a bit more about what this does??? I understand that the first set of numbers requires a restart, and then the second also a restart. What does it do exactly, what does g_AutoSimSetting mean???

The situation I have, and I've seen similar comments is on a carrier different than AT&T, and the service is pretty bad, there are lots of areas where 3G falls out to E dramatically, or to nothing, and then 3G appears with full bars (where I KNOW IT IS NOT REALLY THAT STRONG) and all data connectivity is lost. Even if I connect to Wi-Fi after that, it won't connect to anything, it is as if maybe querying the DNS it gets stuck and never does anything on data again, no matter the connection. If you restart, everything goes back to normal (the 3G shows now with one or two bars missing which is reasonable in that area).

I got ATT and I have had the same problem since I got my Focus in Dec.

I still have the original diagnostic menu, when it updated I deleted it , got the original back then did all the updates and its still there , *#32489# works , but why bother i can still use *#197328640#

Useful low level apps in diagnosis tools!

I've been poking around on how to interface my Focus to external devices using serial, and most likely a low-level approach. Until I came back here after a month of inactivity I see the most progress for hacking the Focus!

Has anyone tried to use this code:

APPSLAUNCHER = 5**6244*3 (0x33B0B76)

It's the most useful I've tried thus far. From the 3 minutes of use I can surmise that this is akin to a native file explorer.

Some of the files and links can be actively triggered, but in order to properly edit files directly on the phone I suppose your going to need to install apps that bind to specific file extensions.

Here's some of my expirements so far:

1.)I opened an XML file and it took me to a browser (IE) to view it.

2.)While browsing the Windows directory I found links to trigger low-level communication (SwitchUSBToSerial.lnk) for serial... which what I might be looking for. The phone was attached to my computer and well enough, the communication switch to a different protocol because Windows looked for a different driver for the Phone.

Be Warned though: USE WITH EXTREME CAUTION.

I forgot to say thank you! :D

Also, I don't have developer unlock. So this is a big deal for me. :)

I have yet to find a way to the Root Menu since updating to 1122. I see references to using the other menu and hitting back until I hit the root menu... well all back does is eventually kick me out of diag mode to the apps I used before I went to diag.

Further I have read this thread and have found posts such as the following:

EDIT:

dialing ##634# on the phone dialer will bring up the diagnosis keypad

some people are/were able to type *#197328640# into this keypad and get into the "Diagnosis Application TEST MODE" at the "MAIN MENU"

that code didn't work for me, but *#32489# did

if you dial *#32489# into the diagnosis keypad, it should open "Diagnosis Application TEST MODE" at the "CIPHERING CONTROL : ON" screen

from this screen, if you press the rectangular on-screen "back" button once, you get to the "NAS CONTROL" screen

if you press the rectangular on-screen "back" button again, you get to the "PHONE CONTROL" screen

if you press the rectangular on-screen "back" button one more time, you get to the "DEBUG SCREEN" screen

if you press the rectangular on-screen "back" button for the fourth time, you get to the "MAIN MENU" screen
[Focus General] crg1970:
Anyone know what the comma is supposed to mean??? Since after the first set of numbers it asks for a reboot, I thought that after the reboot you go ant type those other numbers, but it seems to do nothing, as the bookmarks or homepage aren't changed and it does not fix the problem. Could it mean to NOT accept the reboot and type the other quotes right away???
[Focus General] MRWRANGLERS1:
when typing the *#197328640# code nothing happens. Ive used this before following this thread, now when i try to use it nothing happens. I deleted the diag app and reinstalled it and still the same thing.

For those who can't change default At&t default apn for internet and mms lines, just read a thread here in xda how autoconfigure default at&t apn even if samsung network tool doesn't work for you carrier.

First, verify the default apn settings typing *#9920#

Then, just type 40*047#3 to enable autoconfigure sim setting. A message brings asking to restart the phone. Restart it.

verify the change in default apn setting typing *#9920# again.

Done.

For disable autosim setting, type *#94765#.

Now my focus works great with telcel carrier.

I was toying with the "Sound Tuning" options in the diag menu and somehow managed to turn off my speaker all together. Headphones seem to still work.

Does anyone have the default values for each box for diagnostic v1122. Not sure if version number makes a difference but just wanted to make sure.

I do not have Mango. Also if anyone has experienced this and fixed it without a hard reset, please let me know how.

Full Tethering Step by Step Guide (Works on Windows 7)

Preparing the Samsung Focus to Tether

On the Focus, go to the keypad and dial ##634# and hit call button

Diagnostic Keypad will come up (Installs Diagnostic App, you won't have to do step 1 again)

Dial *#7284# which will bring up the USB Path Control settings…

Chose USB Modem Tethering Call.

Plug USB cable into phone and into your PC.

Computer will install the drivers automatically (NOTE: You must be online to download the drivers)

Initializing External Samsung Modem

Go to Start Menu

Type in Modem

Click on Modems Tab

Select Samsung Mobile Modem

Right click on SAMSUNG Mobile Modem icon and click on Properties

On the General Tab, click "Change Settings"

This will unlock the Advanced Tab where you can input the Extra Initialization Commands

Switch to Advanced Tab

Type in under Extra Initialization Commands: AT+CGDCONT=1,”IP”,”wap.cingular”

Click OK.

Connecting to the Internet

Now under the Start Menu type in: Connect to the Internet

Click on New Connection

Click on Dial Up

[Focus General] munkeyphyst:
about that^

just as a side note, putting your phone into tether mode will turn off the ability to sync your device with Zune. You'll have to go back into the diagnosis app at *#7284# and select sync to get the sync back. In other words, turn on tether when you want to tether, and turn on sync when you want to sync.

[Focus General] ppczouz:
I just noticed something cool, I don't know if is common knowledge or now:

I need to disable 3G and change the USB behavior from Zune to Thethering frequently. So I was trying to memorize the codes when i found out that they actually map to their actual names on a phone keypad:

to change band:

*#2263#, which is the same as *#BAND#

to change the USB path

*#7284#, which is the same as *#PATH#

to launch FM test

*#0368#, which is the same as *#0FMT#

of course, not all are like this, but the fact that the ones I use most are like this is cool :)

[Focus General] sumorabbit:
To get to the root menu, go to diagnostics and type *#32489# then just hit the back button (on the screen, not the hardware on the phone itself) 4 times.

That code brings you to the Ciphering Control setting, then the back button takes you through the menus until the 4th tap which brings you to the main menu that the *#197328640# used to.

Sorry I can't help on the mic settings. I know this sounds stupidly simple, but have you tried cleaning out the tiny mic hole on the bottom of the phone? Mine had pocket lint in it and that greatly degraded my voice volume and clarity during calls.
[Focus General] Vintage144:
the mic settings have to do with the audio , I cant remember exactly this happened to me awhile back I believe its in the middle of this thread , you have to reset the get gain settings ,you'll have to play with it to get the settings you want , the mic is getting interference from the ear piece, no big deal!

Mic Issue? I Guess I've fixed mine..

Hi,

I'd like to thank everyone whose tried to help me with my focus mic issue.. I was driven to the verge of a hardrest and thought,if Hardset is the only way, why dont I fiddle with some reg keys.. The saddest part was that there were no reference available..

I took a chance and tried to follow the WM reg key changes and with reg editor 1.2.0.0 (thanks to Julien Schapman) I searched for keys similar to the ones in WM 6/6.5 used to tweak mic volume, like "mic" "audio gain" etc. I played around with few keys for over 10 days now and My issue with Mic is gone if I use the following reg edits

HKLM/software/samsung/Audio here my DualMicState was "0" and EnableDualMic was "1". I changed these as "1" and "0" respectively. And I haven't heard a complaint yet from the other side that my voice is feeble;). Pls note that we cant keep both the keys at "1" for it falls back to the original state after a reset and people would no longer hear you.

P.S. I do not know what these reg edits really do. Of desperation I tried something and it seems to have worked. I take no responsibility of your device damage. BUT IT WORKED!:D

If someone could explain the real reasons why it worked that would be great.. I am posting this in the tweaks forum as well just to get some expert to comment on it. Thanks
