Firmware

The software that makes up the entirety of your phone. The firmware consists of

GDFS

This piece of firmware contains the settings, attributes, and essential components needed to make the phone fully functional. Damaging this will automatically corrupt it, rendering your phone useless. This guide will explain how to backup this necessary component incase it becomes corrupt. Backup of this is necessary because this component is unique to every phone, meaning that no two GDFS will be the same. Flashing a different GDFS, whether it says it is clean or not, will result in an automatic death of your phone.

FS ( FileSystem )

This firmware file contains all the files that run your phone (Sound files, menu files, etc.) Every time you flash a new FS onto your phone, you will need to apply a Custompack to the phone, or you will experience an error.

MAIN

The Operating System (OS) of your phone. Without this, the phone will not run, and will not turn on properly. After a MAIN file has been flashed, the phone does not need to be customized.

Custompack ( Customization, Custpack )

This is usually a directory that contains files the initialize, or activate, the phones FS. Without this, you will get an Error whenever you start up your phone. Every time you flash a new FS onto your phone, you must flash a Custompack. Flashing a new MAIN, however does not require you to flash a Custompack. However, flashing a MAIN and a FS at the same time will require a Custompack, because you flashed a FS.

XS++

A program that is very useful and easy to flash your phone with. I personally prefer this over SETool 2 Lite, because as many people say, SETool 2 Lite is a GUI minefield, in the sense that all the buttons are crammed together, and if you’re not careful, pressing the wrong button will kill your phone. XS++ is the prime tool for debranding your phone, because you can flash a FS, MAIN, and Custompack in one flashing session. This guide is now using XS++ 3.1, which supports Second Generation FSX

FAR + SEFP

FAR + SEFP is a method used to gain access into the phones filesystem. By utilizing FAR Manager (created by RARLabs), a member of SE-NSE named den-po was able to write a plugin called SEFP, which allows access to the filesystem. This method requires a “fake” MAIN file to be flashed in order to work. Note that this method is somewhat outdated. The only thing keeping this from being outdated, is that it can copy files from the filesystem onto the computer, other than that, it is not worth the hassle

Bruteforce:

A method used by all XS++ versions below 2.0 to gain entry to the phone. XS++ would repeatedly try to enter the phone by trying a complex series of passwords. It should be noted that Bruteforce can take 4-6 hours. This method is no longer used.

Break-in

A method used by XS++ to gain entry to the phone by sending break-loaders to the phone, thus bypassing the passwords completely. This method is drastically faster than Bruteforce Hacking.

Flashing

Most people refer to flashing as something that is added to the phone. It is not, in fact, Flashing is actually when XS++ is writing files to the phone, instead of uploading files. This is direct, in the fact that no passwords must be hacked. It usually takes around 1-7 minutes depending on what you are flashing

Unbranding / Debranding

A process in which a Generic FS, a Generic MAIN, and a Generic Custompack in order to remove content added to the phone by your carrier (Cingular, Fido, Orange, T-Mobile, Rogers etc.) This process can also be said as “Debranding”.

SETool 2 Lite

SETool 2 Lite is an extremely advanced phone maintenance program created by a Se-nse user named “the_laser”. In this guide, SETool 2 Lite will only be used for GDFS Backup and Patching. As the_laser says, “this tool is not for dumbasses”, in other words, be 100% positive of what you click before you click

Patch

A section of code that is applied to either the GDFS of the MAIN file. Patches are usually intended to make the phone work a certain way you want it to, and they are very interesting in what they do

DCU-60 Cable

The standard data transfer cable intended for File Transfer between Phone and Computer. This is not the same as a Cruiser Cable.

Cruiser Cable/Fighter Cable

A cable that is used for maintenance of the phone. This will not be used in this guide. The only difference between a Cruiser Cable/Fighter Cable and a DCU-60 Cable is that a Cruiser/Fighter is able to produce more volts than a DCU-60 can, and they are usually self-powered. This means that data transmission between a Phone and Computer connected with a Cruiser cable is faster and more reliable.

USB Flash Driver

A driver that must be installed into your computer in order for your phone to connect to SETool 2 Lite and XS++. The most common driver is called “ggsemc”.

Foreword

Hello Readers, First off, I would like to express my gratitude to all of resource they are truly wonderful.
Anytime I had a problem, they were there to help me. All of they are so experienced, and if I had never found Se-nse, I would have never had the courage to start modifying my phone. Even more importantly, I would like to thanks these sites: se-nse.net (for giving me support and what to do when I was close to killing my phone for good), se-ven.net and XS++ crew (developing such an easy tool for flashing!), the_laser (developing SETool 2 Lite, and putting up with some junk that people give him about SETool), estato.com (answering some questions about patching), masterbiji (explaining modding to me), topsony.com for providing a PDF version of my guide for me, and the many more of they that have not contributed much, but little things such as answering my questions on flash menus etc.
This guide is geared on towards CID49, Red Retail W810 Walkman Phones. Most new W810 Walkman Phones are created now using CID50+ Protection, which may render some programs/firmware/modifications defective, and may end up harming your phone. Before you start modifying your phone (which I am sure you are all eager to), I would like to inform you of some potential risks. First off, there is a slight chance that you can brick(kill) your phone. While this guide will explain every step to prevent this, and possible fixes, it cannot always be resolved. So, if you are too worried, then phone modding might not be for you.
