Nokia 5300: Part 2 The Security Code

A Writeup by The Giornale give a tutorial on how to reset the security code ( re-invent the wheel?). The only problem being if the security code is active, the phone will not sync to a computer to use this method. This is where the hacking comes into place.

This guide will follow the "Giornale" writeup, but interject on how to enable the phone.

Start by Downloading Nokia PC Suite 6.84.10.3. Megauploads has a version that works. The password for the rar file is www.fullandfree.info

When installing NSS, make sure to choose virtualUSB in the multiple options that prompt on install, other options are designed to be used with serial--usb cables and standalone hardware.

After installing PC Suite, install NSS as previously posted or according to "The Giornale" guide. What follows is what sets this procedure apart form all the others

The phone will only sync to the computer in Test or Local mode. These are service only modes that are usually reserved for the carrier or manufacture for maintenance. In order to remove the security code and debrand the phone, one of these two modes needs to be achieved.

The phone achieves this by changing the voltage and amp values being fed to the phone. If you wanted to use the battery that came with the phone, resistors and alligator clips would be in order, but a bench power supply is the easiest and most versatle option. If you dont have access to a bench power supply, you can attach a (7.5k~10k) resistor to the negative lead and use the battery that came with the phone. I would recommend using the power supply, as this is what I used to succeed.

***NOTE: following this process has the potential to damage the phone if the guide is followed incorrectly or the user is not skilled enough, if your not sure, consult a friend who works in electronics... for real)

The battery terminals on the phone are as follows:

( The camera and mini-usb are facing downward)

The battery clips are able to be attached to via hook clips that will grab onto the terminals and insulate them from each other.

I I I

(-) (gnd) (+)

hook all three up to the power supply, and set the input voltage between 3.8v~4.2v and the amp value between 0.06A~0.12A (<-- milliamps!)

It will take some playing with the phone to get the phone to boot into a service mode. It will boot normally, and shutting down the phone and restarting it until it hits Local or Test takes time and practice.

Once it enters Test or Local mode, then the phone can be connected via mini-usb to a computer and these steps can be followed:

Steps:

1. Install Nokia PC Suite v6.84.10.3
2. Download and install Nemesis Service Suite
3. Enable Local or Test mode on the phone
4. Run NSS
5. Click the magnifying glass at the top rightmost corner of the application screen.
6. Click Phone Info button at the top (beside Device Info)
7. Click Scan, under Actions.
8. Choose Tools from the buttons on top (Beside Security)
9. Tick Full Factory radio button, and then click Reset.
10. Go back to Phone Info,and then choose Normal under Power Mode and then press Change.

And.. that’s it! The default has now reverted back to 12345, you should now be able to change the security code.

Nokia 5300: Part1

The nokia 5300 XpressMusic phone an Series 40, and an updated verison of the Nokia 5200. T-Mobile picked up the 5300 around march of 2007.

The first part of this hackup will be the prep work to remove the security lock and debrand the phone.

Debranding a phone is the term for flashing the generic firmware created by the manufacturer to remove the features and items left behind from the Carrier. (ie. T-mobile T-zones and wallpaper)

By flashing the generic firmware of the phone, any features that were locked or hidden will be available, including running third-party applications such as google maps or Opera Mini.

When I purchased my 5300 Xpress from Ebay, it was listed as prompting for a "security code". The security code restricts physical access to the phone. An example would be your "buddy" attempting to look up numbers for your sister or girlfriend in your phone. Without the security code, "broseph" cannot use the phone at all. The only downside to this being if you loose your security code, your in trouble unless your carrier/manufacturer will unlock it for you. (Note: T-Mobile is not able unlock 'security codes', and Nokia will only unlock it under warranty. An unlock outside of warranty exceeds the cost of the phone itself)

To remove/reset the security code, certain software is necessary.

Nemesis Service Suite is a software suite designed to go with certain hardware unlock setups, but works with miniusb fine.

NSS will allows us to both debrand, and remove the security lock.

Also necessary is the Nokia PC Suite, for necesary USB Drivers
