[Galaxy Y GT-S5360 and Duos 6102 Q&A, Help & Troubl] TheFixItMan:
If the rom is odex you will see .odex files in system/app and framework

To deodex follow these steps

Requirements

Pc

Android kitchen

Cygwin

Rooted phone with Busybox & terminal emulator

Winrar

Notepad++ (different from the windows notepad)

Alot of patience & a little knowledge

Please note I'm writing this from memory - some steps may vary

First root your phone & install Busybox (open app & click install) from the playstore

Also install terminal emulator

https://play.google.com/store/apps/details?id=stericson.busybox

https://play.google.com/store/apps/details?id=jackpal.androidterm

Set your screen timeout to 30mins

Open terminal emulator

Type the following (a new line represent push enter after the line before)

Su

tar -c system/* >> sdcard/system.tar

Note it may take around 5mins to complete - You will know it's done when the prompt cursor returns

This will copy your phones system folder to the root of your site

card and call it system.tar

Copy this tar file to your pc

Next head to this thread

Download and install Cygwin and Android kitchen

There is a YouTube video which explains how on the thread so watch it

This is the part I can't remember exactly from memory

You need to setup a working folder - I can't

remember if you place the tar file in the rom folder in the kitchen directory or you unzip it & copy it to a working folder - that thread will say

Start Cygwin as administrator (right click on icon & run as administrator) if you get a load of errors turn off your antivirus

Navigate to your kitchen folder (you can bring up a list of folders by typing ls and type cd to change directory

Type ./menu

Kitchen will start

You have the option to create a working folder which will look in the rom folder - if a tar file is acceptable it will extract your tar into a working folder - can't remember if that's how you do it

Next goto advance (or extra options can't remember what it says)

Goto deodex

You need to change the api level so it matches your Android version

Now you are finally ready to deodex

Deodex both folders

Once done build the rom (lazy mode options should be fine Think it signs rom create scripts & so on)

Once it's built collect your rom zip

Now download any custom stock rom - maybe hyperion 9 for 5360

Open your rom zip with winrar

Delete boot.img if present

Goto meta-inf folder and I think it's in com/google/andoid

Delete the update binary and replace with the one from hyperion9

Next open extract the updater script from both roms from the same folder the binary way in

Open them both in notepade++

Replace everything in your script above where the symlinks start with what is written in the hyperion9 one

Save & copy this script back to your rom zip meta in folder replacing the one that is there

Copy zip to sd card

Go into Cwm

Create a nandroid backup

Format system data cache

Mount system data cache

Flash your rom zip

Error codes

Status 0 wrong update binary

Status 6 error with updater script

Hopefully there will be no errors and it will flash and when you restart you will have a fresh deodexed rom

You can go into Cwm and advance restore data only

This should restore your contacts sms and app data

For extra storage create a 2nd ext partition on your site card in Cwm (note that this will format your ad card so copy it's contents to a pc then copy back once done)

Once you have a 2nd ext partition you can download link2sd from the playstore and link apps to sd card - you can also use the app to uninstall bloatware from the system

Note you will need to use a kernel that supports ext and try ext4 first from the link2sd menu that will pop up & work your way back up if that fails

I don't normally post such a long explanation but I'm feeling generous - anything else please research yourself
