[GUIDE][New User Friendly]How To Make Custom Roms(Under Construction) - Sony Xperia P, U, Sola, Go

Hey Guys,
First of all this is not a guide to build a rom from source.
Instead of downloading roms made by other users,you can make your own
And this is not a guide for NOOBS it is for NEW USERS who don't have enough knowledge to build custom roms.
NOTE : I AM NOT RESPONSIBLE FOR ANY DAMAGE TO YOUR DEVICE
Things You Need Before Starting :
*7zip/Winrar
*Notepad++
*A Working Brain
Follow each step carefully to get a working rom.
1-First download the .zip file according to your device provided below and extract them.
2-You will get two folders;system and META-INF.
3-Go in system folder and open apps folder.
4-You will find all the system apps here,remove bloatware if necessary.Two Most important files are Home.apk and SystemUI.apk which are faces of your custom rom and without them your rom will be like a pizza without cheese.
5-Replace Home.apk and SystemUI.apk with the one you choose.(You can find plenty of them on XDA,Just keep in mind don't put paid launchers like Apex Launcher Pro as it is not allowed on XDA)
6-You can also replace Browser.apk,Conversations.apk,MusicWidget.apk,SoundEnhancement.apk,Phonesky.apk(There are many themes versions available on XDA),SemcMusic.apk according to your choice.Now you are done with apps.
7-Now go to media folder and replace bootanimation.zip with the one of your choice,you can also add extra ringtones(But I don't recommend this as this makes your rom heavier)
8-Now we are done halfway.Lets head on to build.prop.(Its device specific don't replace it just edit it)You can find build.prop tweaks in next posts.
9-Now go to META-INF/com/google/android and open updater-script with Notepad++(This is what you see while flashing the rom,so keep it short and helpful)
10-Again put this modified folders in a .zip and give your rom a good name.
I recommend to use Devhost for uploading your roms.
And you are ready to open a new thread on XDA for your own Rom
And ya,don't forget to test it yourself

EDIT : I will not upload the .zips(Slow Upload Speeds) but will give you the procedure.

build.prop Edits
Add these lines at the end of your build.prop to enable the tweaks.
Signal Tweaks.(Don't expect much from these)
Code:
# Signal Tweaks
ro.ril.hsxpa=2
ro.ril.gprsclass=10
ro.ril.hep=1
ro.ril.enable.dtm=1
ro.ril.hsdpa.category=10
ro.ril.enable.a53=1
ro.ril.enable.3g.prefix=1
ro.ril.htcmaskw1.bitmask=4294967295
ro.ril.htcmaskw1=14449
ro.ril.hsupa.category=5
Network Tweaks.(They can cause a little difference)
Code:
# NetSpeed Tweaks
net.tcp.buffersize.default=4096,87380,256960,4096, 16384,256960
net.tcp.buffersize.wifi=4096,87380,256960,4096,163 84,256960
net.tcp.buffersize.umts=4096,87380,256960,4096,163 84,256960
net.tcp.buffersize.gprs=4096,87380,256960,4096,163 84,256960
net.tcp.buffersize.edge=4096,87380,256960,4096,163 84,256960
2D Tweaks.(These are must have tweaks)
Code:
# Touch Responsiveness
debug.performance.tuning=1
video.accelerate.hw=1
Performance Tweaks.(No Idea)
Code:
# Performance Tweaks
ro.kernel.android.checkjni=0
ro.config.nocheckin=1
Happy Editing !!!!!

How To Pre-Root Your Rom
Download THIS .zip and Extract It.
Add The Files From Folders In The .zip To The Folders Of Your Rom.
And Add These Lines To The Updater-Script In META-INF Folder(Not Needed If You Are Using My META-INF) :
Code:
set_perm(0, 0, 06755, "/system/xbin/su");
set_perm(0, 0, 06755, "/system/bin/su");
And Your Rom Will Be Ready To Use.(With Root :good
Hope It Helps.

Procedure For Extracting System Files From .ftf
Needed :
Flashtool
WinRar
ext2explore
Steps :
-Download the latest .ftf file for your device.
-Open it using Winrar
-Extract system.sin from the .ftf by using WinRar(Alternative : 7zip)
-Open Flashtool.
-Go to Advanced>Sin Editor And Select the file(system.sin)which you had extracted and click on Dump Data
-The .ext4 file will be created in the same folder in which system.sin was located.
-Open ext2explore.exe(As Admin)and navigate to the folder containing .ext4 file and open it.
-You will now get access to the system files but still they need to be extracted.To extract them from .ext4 right-click on the needed folder and select extract.
-Now you will get the needed folders to cook your own rom

Thanks! i will try this myself as soon as this guide is complete..

If I use Root explorer and replace framework apk and home apk and then edit the build prop and do whatever else I want to customise the rom then backup with CWM will I get the same result?
Will others be able to install my backup?
I will try your method as building from source requires programming knowledge.
Thanks for your guide, I see your quite busy around Xperia section so thanks for supporting our devices
