Field Test Mode on Nokia Symbian Phone June 2009 Update

The following steps apply to Nokia Symbian phones. To be more specific, it should work with S60, FP 9.X Symbian phones. There are many hacking tools around the web and I am confuse at the beigining what steps I should do to install the Field Test Mode or Net Monitor to my phone. Some old methods are no longer work and therefore I try to write the steps here to remind myself. The following steps is tested in June 2009.

In brief, you need to have the following stuffs to install FTD:

1. A Cert and Key to sign some hacking applications.

2. A SIS signing tool.

3. HelloOX v1.0.3 This is the application to allow us access the hidden system folders.

4. FTD files or installation (.sis) file. You need to copy files or install signed FTD apps to provide the FTD function.

1. How To Get a Developer Cert and Key for free

To get a cert & key for your Symbian phone, go to the famous OPDA to get a cert for free. OPDA is a Chinese forum and generously provide free cert for Symbian users. If you don’t know Chinese, visit and follow the step-by-step tutorial. It should take to around several hours to one day to get the cert and key. One thing need to point out is that the forum will ask you to provide your 11 digits phone number that started with 13, 15 or 18. Just provide any number start with 13, 15 or 18 and it doesn’t need to be your number. But try to make it random enough so that it won’t be used by other to avoid collision.

2. Signing Tool
You can use any signing tool available. I get the sigining tool from here - 664.2 KB

3. HelloOX v1.0.3
Use this version or later one. I have tried v1.0.1 with no success. V1.0.1 has to rely on another application called mapdrive. In V1.0.3 Mapdrive is integrated into HelloOX and hence you don’t need to trouble about it. Get it from the link here:
HelloOX v1.03.rar - 186.9 KB

Sign the HelloOX with your cert & key. Install and Run it.

With my Nokia 5320, it took me very long time in the “Install Root Certificates…” step. Therefore be patient during the installation.

After install ROMPatcher, HelloOX will try to remove some files. In my case, it just hanging for 30mins and I just press the “cancel” button to complete the installation.
After the installation, you should find an “LeftUp” Item in your phone. Open it you should see “Modo” application. Open “Modo” you should able to see the hidden folders like “Private” and “SYS”. Now you are very close to success.

4. Install the FTD files
There are two ways to install the FTD files.

Method 1: Sign packed sis file and install it. Get the file here:
12 Mar 2010 Update: badongo link is dead. File is uploaded to rapaidshare :

It should work for some models but not all. If the installation fails, use method 2. My N5320 doesn't work with this method.

Method 2: Copy the FTD files to specific folder by using “Modo”.

Download the FTD files from the following link:
12 Mar 2010 Update: badongo link is dead. File is uploaded to rapaidshare :

Copy the respective files to corresponding folder as below:







If a specific folder cannot be found, just create it yourself. After you copy all the files, you should able to see the "Field Test" icon in the Application or Application->My Own folder of your phone.

But if your phone is FP9.1 (My 5320), the icon will not be shown and you need to override the Ftd.mbm, Ftd.mif, Ftd_aif.mif with FP9.1 version.

5. Done! Enjoy your test mode.

6. Confirmed model:
N85, 5800, 5320, 6120 Classic. The critical step is to be able to access the hidden folders.

9 Mar 2010 Update:
The download links are dead in badongo server as mentioned by one reader. I shall upload the files again when I back to home (around 13-14 Mar 2010).

12 Mar 2010 Update:
Files are uploaded again.

Please anybody help me, I just did everything as says the post but when I click the Field test icon it shows "loading configuration" and never stop unless shut the mobile off. The model is Nokia n85-3

I also follow the steps and active the netmonitor sucessfully in N85.

Make sure you have follow all the steps. If some directory is missing, you have to create it manually.

Share with us when U hack it!

Good luck!

Let me ask to you a question, do I have to do something before copy the files into the pointed folders?
What is rompatcher for?

Gabriel January 24, 2010 at 1:35 PM  

You just won't believe it, I was hopeless by this moment but when cheked up each file again I saw a repeated one that was screwing FTD to me.
It works now!!
Sorry for the emotion :)

Very good!! It's working in my nokia 6210 navigator. I used the hellox and the FTD for symbian 9.2 although my nokia be symbian 9.3.

Hi. Would you know once netmon is installed in a 6120....would it be possible to connect the phone to TEMS 9? thanks.

Anonymous July 2, 2010 at 2:13 AM  

FTD enabled 6120 cannot connect to TEMS. TEMS phone need special license inside the phone. Usually TEMS supports Sony Ericsson, Qualcomm chipset and Samsung chipset handsets.

Many Thanks for comprehensive procedure. I sucessfully installed Fieldtest on my Nokia 6120c. I was able to install Fieldtest just after running the HellooX( i.e. Method 1 of step 4). Both HellooX and Fieldtest applications are available under "Menu>Applications>My own" in Nokia 6120.

Best regards

Works fine on Nokia C5.I just get the certificate from the link and signed the application Fieldtest 9.2.sisx with SignTools 2.2.Not working with HelloOX.

Girleanu January 22, 2011 at 2:22 AM  

It works on E5, but you will have to sign your HelloOX/Fieldtest on the site which gives you the certificates! The chinese one mentioned in the tutorial above. You have a (english) language selection button in the top right corner. If you press it you will know what to do after! :D

Thanks a lot for this TUTORIAL!! VERY HELPFULL!!!

hi. i own a nokia c5-00 with 062.10 firmware.
i installed Field Test 9.1(and 9.2) and the phone shows "x" values instead of real figures.
any idea ? thanks.

Electro : your phone may be working in WCDMA. Try checking page 41.xx for WCDMA.

Sad news !!! OPDA has just stopped giving certificate and keys

I guess getting the signed HelloOX by donating to HelloOX should work. But phone models are limited anyway.
