Cross Flashing K800 to K810 CID52 [SE Modding]

So, first of all, you'll need :
- SEToolLite 2 or XS++ (I'll show you how to use both of them)
- the MAIN and FS of the K810 firmware you want to put on the K800
- a finalisation file for the firmware
- some other files that you might need, for example the "lighteffects" fix.


Here are the files :
Firmware + finalisation :
Download Firmware K810 R8BA024 Generic Here
Flashing programs :
Download SETool Lite Here

Patches/fixes/addons :
K800 Light Effects (on 4Shared)

Drivers :
K810 SIGNED Drivers (on 4Shared)

The Service Menu:
First of all, lets find out what CDA is in your phone, that's going to be used to determine what kind of Finalisation (Customisation) we'll use.
For that, press : >*<<*<* where > is the right joystick key, the < is the left joystick key and * is of course the * key :-)
In other words, press right joystick, then the *, then twice press left joystick, then * again, then left joystick and finally the * again. Don't worry if in while you're pressing those keys some menu options are selected or the radio starts or stuff like that, just finish the key combination and you'll get to the Service Menu.
This menu can give you a lot of information about the phone. What we want for now is to note the CDA that is currently in the phone. For that, select Service Info->Siftware Info, scroll down till you see the Customisation line, note the text that's under it. For example it might be "CDA102568/207 R2A ...", we're interested in the CDA10256 part. Them when you look for customisation, search for the same CDA version.


Setup :
So, after getting the files lets start by putting the MAIN and FS files in a folder (lets say c:\K810\Files), extract SETool2Lite (or XS++) somewhere (for example in c:\k810\SEToolLite2, or c:\k810\XS++), copy the finalisation archive somewhere where you can find it (for example c:\k810\files).

Now let's start the patching :

SEToolLite2 method :
1. save any data (SMS/Phone numbers/files) from your phone using MyPhoneExplorer (or similar programs) and also backup your phone's internal data using THIS TUTORIAL

2. shutdown the phone : THE PHONE HAS TO BE OFF DURING ALL THE FLASHING STEPS

3. start SEToolLite2, select the phone type, in our case it's K800

4. before we do anything "strange" with the phone we should backup the GDFS (so later on we ca use it if we get into trouble), for that press the "Read GDFS" button and you'll see a message "Hold 'C' and insert USB cable", that actually means that you have to connect the phone to the computer while pressing the "C" button on the phone (we're using the DCU60 cable that came with it).
Now you'll have to wait a little while the GDFS is being backed up (it might take a while, for me it took about 1-1.5 minutes, so be patient)
You'll see a new file GDFS.BIN where SeToolLite 2 was started from, that's the GDFS file, you should make a copy of it somewhere safe and give it a good name, for example : "GDFS_backup_from_k800.BIN"
Now disconnect the phone (take out the connector from the phone)

5. We have to modify the "Finalisation" file to include the "lighteffect fix" or the upper buttons (1,2 and 3) from the keyboard won't be lighted up with the rest.

5.1 first extract the lighteffects_k800.zip file and copy the TPA folder that you got from the archive.

5.2 open the finalisation file, in our case "HB1_06_Gen_CDA102568_4_R6A_GENERIC_MEDITERR.zip" file with explorer (or any of you favorite archiver) and paste the previously copied folder. The idea is to add the files from lighteffects_k800.zip to the finalisation file and keep the internal directory structure of the archive.

NOTE in step 5 you can add any custom files, for example custom Acoustic or Camera drivers, just copy those to the archive.

6. Now let's actually patch the phone, for that in the Files section press "Add" button and add both the MAIN and FS files (i don't think it matters in which order), and under the "Misc Files" press the "..." button (near the "E" button) like in the photo :
.
When you select the right MISC file then on the left side you'll see a message with what "variant" the customisation is and what languages it supports.
Now press the "Flash" button and you'll see again the "Hold 'C' and insert USB Cable", if you forgot to take out the cable in step4 you can take it out now and reconnect the phone. You'll see a few messages and you'll see that in the left side (where the list is) there are messages like "copying chunk 100/406" or similar. Now you really have to be patient, this step can take up to 10 minutes (took about 3-4 minutes for me, but might take longer for others). When it finishes you'll see this message : "Phone detached" and the buttons are once again usable (the Flash/ReadFlash/Read GDFS/...), that really means that you've now have a k810 phone :-D
