[TUT]Tutorial for making Custom Rom - Sony Ericsson XPERIA X10 Mini

Today I went to computer center and tested.
Finally,I got a full working custom rom.
Note:Now,I don't have computer at home.
My dad shifted the computer to his room(another house) due to my final year exam.
Now explaining all these steps with my remembered things at center.
Sorry,I'm not responsible if anything goes wrong.
Synopsis:
1.Making a Kitchen
2.Create a Stock Base Rom
3.Making Custom Rom
4.Finished
1.Making a Kitchen:
Code:
You must install a Kitchen properly.
To do,
Download a dsixda kitchen from Chef Central Forum.
Install it properly according to that post.
Short synopsis for windows:
1.Download all necessary things.
2.Install Java.
3.Then install cygwin.
4.Copy the kitchen to home folder.
Now your kitchen ready.
Test the kitchen by running it.
Type ''./menu'' in cygwin
It will show Main Menu.
Don't go to next step until you prepare Kitchen.
2.Create a Stock Base Rom:
Code:
From this stock base rom we can made a custom rom.
First reinstall a Android 2.1.
Then root it.
Install a XRecovery.
Then backup it.
Now you will get system.img in backup folder.
Then copy the system.img to your kitchen folder "original_update"
In new version of kitchen you don't have to create fake file.Skip next step.It will automatically created.
Make a fake file called "boot.img"(empty file).
Now Run a kitchen by typing in the cygwin
./menu
You will get a main menu.(if you installed properly)
Choose option 1 and press enter.
Again press Enter.(now your system.img will extract)
It will take above 5min to extract.
At last you will get a question asking ''you want see the rom details'' for that press n(No). Bcoz we don't have boot.img.
Then it return to main menu.
Now minimise the cygwin.
Then you will get working folder in your kitchen.
Stock base rom created successfully.
Backup this base rom.
It will useful for future Re-use.
3.Making custom rom
From Stock base rom modifiy what you want in your system folder like removing unwanted apps,add new theme,root option,etc...
4.Making update.zip
Maximise the cygwin and choose option 99.
Your rom will be created and signed in output_zip folder.
Installing Rom using Xrecovery.
1.Copy the zip to sdcard(rename it to update.zip)
2.Go to Xrecovery.
3.Factory reset(Full Wipe)
4.Then install update.zip
Hope this you can understand and work.
All the best.

ill wait for your working rom.. suddenly i got excited

---

I wonder what is the difference betwen this custom rom and those you get backing up your rom?? I understood that you need a rom to modify apps in /system...
Please explain the differnce.

---

We can't take system directly from the device.
So from backuping we can get system.
Then modify what you want in the system like removing unwanted apps,adding new theme,etc....

can i skip this step here? can i use my old rom just want to add/edit something..??

---

First time we want system.
Then we can use the previous one.
Now you can skip those steps.

Ok, i've got to step with removing apps... Problem is, that i have App2SD and those apps which are stored at card are not there (in working folder). Therefore it seems that if i will give that update.zip to someone, he will be missing some apps won't he? Or are they somewhere and i am just blind?

---

question on system.img
could i use a system.img file converted from system.sin decrypted from update files for this tutorial?
