Now, this whole part is completely optional, because patches are just designed to make your phone function differently. If you like your phone how it is unbranded, then skip this. But, if you want to explore patches, then read on. But, please note, that patching does involve a certain percent of risk, meaning if you click one wrong button, your phone will be dead. But we will make sure that won’t happen.
Open up SETool 2 Lite. Unlike XS++, where you must connect your phone first, SETool 2 Lite allows you to select what you want to do before you connect. So, first off, to make sure your phone doesn’t become irreparable, we are going to back-up your GDFS file. Look to the left column, and four buttons down you will see a button called “Read GDFS”. Click it, and then hold down the C button on your phone, and then plug in the cable. SETool 2 Lite will then say some things, and eventually it will get to a point where it says “PROGRAMMING FLASH”. Once it says Unplug the cable etc. etc., then Unplug your phone, take the battery out, put the battery back in, hold down C, press the “READY” button, then plug the phone back in, BUT right after you plug it in, about 2 seconds after or so, release the C button. SETool 2 Lite will now read the GDFS, and you can watch it say all its technical terms and such, and then it will say “Getting GDFS Chunk” etc. etc., and then once it has fully read your GDFS, you can click “Quit”. If you are not sure when it is done reading the GDFS, just leave it there for about ten minutes. Now in the system tray of your computer, click the green arrow icon, and eject your phone. Take the battery out for about twenty seconds, and then put it back in.
Now we will actually patch your phone. This is very risky, so pay attention! In the MISC. Box, browse for the .vkp file. Once it is in the field, click "Write Script", be sure NOT to click "Write GDFS". Follow the instructions like you did when you Read the GDFS. When it asks you Yes or No, click No. Yes will remove the patch if you ever decide to remove it. Soon, it will finish. Take the battery out of your phone when it is finished, replace it after 20 seconds, and then start up the phone and see what happened. If anything goes wrong with the patch, there is a simple fix. All you must do is connect again, and apply the patch, except this time when it asks Yes or No, click Yes, and the patch will be removed. If your phone is still not working, write the backed up GDFS to your phone. If worst comes to worst, just flash a new MAIN file to your phone along with a GDFS. Near the beginning of the guide, I said I would talk about a patch that would unlock your phone.
