[MOD] Theme updater for Windows/Linux

Hi everyone,
Imagine that you are updating two or more themes for roms like OpenDesire/Defrost/CyanogenMod (I'm pretty sure that this updater works for every AOSP rom but I didn't try), that in one week can be updated at least 4 times. Don't get me wrong, the updates are appreciated, but updating all the themes for all the new versions gets old in no time.
So, I made myself two scripts, one that runs on Windows (this is the first one so is no so updated, but if I see that people use this I'll be willing to create a C# version) and another for linux (bash script), that do this work for me.
This scripts, decompile, copy the modded file (for the status battery), compile the framework again and then add the new images to the framework. After all that it generates the update.zip file for each mod so they can be flash using the recovery (Clockworkmod/Amon Ra/even the default recovery).
Windows Version 1.0
Linux Version 1.0
In the second post, I'll put instructions explaining how to configure the scripts.
Credits :
Brut.all for APKTool.
Daneshm90 for the APKManager (It give me the basic knowledge to create the first versions of the scripts).

Instructions :
Windows.-
If you want to update more than one mod at the same time, you need to edit the script.bat file and modify the "start:" seccion like this :
Code:
:Start
if "%jumpmod%"=="0" set mod=MOD1
if "%jumpmod%"=="1" set mod=MOD2
if "%jumpmod%"=="2" set mod=MOD3
if "%jumpmod%"=="3" set mod=MOD4
if "%jumpmod%"=="4" goto end
set jump=0
goto Create
In order for this to work you need to put the original framework-res.apk in the folder "original"
The mod files have to be in MOD/Images (images you add) and MOD/Xml (xml to recompile). Right now the script is only prepare to recompile the xml for the status battery.
If you add more than one mod, the folders name must be the same as in the start seccion (MOD1, MOD2, MOD3...)
You must have installed Java JRE
Once you configure the script, run it, wait for it to be done. Then go to the result folder and you will find the update.zip file/s.
Linux.-
If you want to update more than one mod at the same time, you need to add as much folders as mods you want in the mods folder. The new folders must have the same structure as the default one.
The mod folders contains one folder to put the images to add after the framework have been recompile (MODNAME/add/drawable-hdpi) and one folder for the file that are used to make the mod (MODNAME/mod/drawable for the XML and MODNAME/mod/drawable-hdpi for the necessary images).
In order for this to work you need to put the original framework-res.apk in the folder "original" or you can download the original Rom by using the script (it extracts the framework-res.apk from /system/framework/).
YOU MUST configure the variables within the script.sh to set the initial path of the script and the path to copy the resulting update.zip files.
In order for this to work you must be ROOT (This is because the apktool, if anyone have a workaround please let me know)
You must copy the following files to /usr/local/sbin/ for this to work :
Code:
/theme_updater/other/7za
/theme_updater/other/aapt
You must have installed openjdk

Windows.-
Version 1.0 - Initial release
Linux.-
Version 1.0 - Initial release

thanks Zeussn, it worked like a charm when i was using it yesterday

[How To] Basic Themeing

This is a very basic guide to beginning themeing. It is not meant to be all-inclusive, just some simple steps that can be taken to make your own custom theme fairly easily. This guide should allow anyone to be able to grab images they like from any ROM and incorporate them into their own.
I SUGGEST YOU ALWAYS MAKE A BACKUP OF ANY FILE BEFORE YOU THEME IT AND NANDROID FIRST BEFORE FLASHING
Here is a basic overview of changing images in an apk:
1. Get your base file to theme – framework-res.apk, com.htc.resources.apk, phone.apk ect.
2. “Open” apk archive with 7-zip (don’t unzip!) and drag and drop the new images into the appropriate folder.
3. Flash new file.
Now some details:
1. The first step is to obtain the file you are going to theme. The file you are themeing ( i.e. going to flash to your phone) must come from the ROM you are currently running. Always use files from your current ROM as a base, however the images you want to change can come from other ROMs, or you can edit existing ones or make your own from scratch. You can obtain your theme base through an ADB pull of the files from your phone, or simply downloading the ROM zip file and extracting the files you need.
2. Now that you have the file to theme, don’t touch it! OK, more specifically, you won’t unzip or do anything to this file except “open” it with 7-zip (unless this is a market app, but more on that later). You are going to drag and drop the new icons into this file by “opening” it and navigating to the appropriate folder. The images you want to change are stored in the apk under /res/drawable-hdpi. Once you have your new icons from other sources, open your base file and navigate to this folder and drop them in.
3. Now you can flash this new file. I have provided empty zip files that you can place your themed files into and flash in recovery. Place your framework-res.apk and/or com.htc.resources.apk into the /system/framework folder located in the zip file provided. Now highlight the META-INF and system folders and zip them up. You can now place this file on the root of your SD card and flash. System apps can be placed under /system/app in the zip file.
Some more info on common themeable files:
Framework-res.apk – this is the meat and potatoes of a theme. On an AOSP ROM it will contain almost everything you want to theme aside from individual apps themselves. Sense ROMs have another file com.htc.resources.apk, as well as framework-res.apk. Both of these files are located in a ROM under /system/framework.
System apps: These apps come packaged in a ROM under /system/apps. They can be themed in the same manner as a framework apk. Some of these apps include Gmail, browser, camera, ect. Place them in your flashable zip under the folder /system/app.
Market apps: These apps are downloaded from the market and are can be pulled from your phone from /data/app. These files require a bit more to theme. They don’t share the same signature as the system apps and you must resign them using a program such as apkmanger. Place them in your flashable zip under /data/app.
If there are any errors, or if anyone has suggestions please let me know. I may have over looked some details, ect.
Thanks to everyone on XDA who has shared their knowledge and made this a great community!

Thanks that will be helpful

so using this guide we can pull parts and what not from other elements of themes we like and create our own framework to push back? Also, based on what you have, shouldn't it be easy to put this up on bid for hire (?) website to create a program to automate that?

Yes the idea of this guide was to help people pick and choose icons they like in other ROMs and add it to their own. I'm not sure what bid for hire is?

No prob. Let me know if it works for you.

I couldn't get the auto signing to work, but the manual way of doing it worked.

Hmm, I got a boot loop on first try and doing this. Does that mean something went wrong with the signing, or that what I created for the theme was wrong? I used the empty .zip folder and re-zipped it, so I don't think that is the issue.

The signing should be ok. If you are using Amon_ra recovery it wont let you flash an unsigned zip I believe. Are you on sense or AOSP? Are you editing images or just copying from other ROMs?
What you might want to do is just create a simple test file. Change just one image and then flash that. That should let you know that your process is correct.

I using Amon Ra and using AOSP. I was moving some items out of a sense ROM so I guess that is where I might have went wrong. I think I'll take your advice and move just a single image and see how that works for me. Thanks!

I tried again this time I ended up stuck at the EVO white screen. I'm guessing it doesn't like the sense part I'm trying to throw in there. I'll have to try again with a AOSP theme instead.

A couple things to look out for when swapping sense/CM icons - some file names are slightly different between sense and AOSP. Rename any sense icons to their AOSP counterparts and vice versa. Also, double check the image size of the icon is the same in both, i.e. 70x70 pixels, ect. and make sure you are not adding images that don't exist normally in the framework. For example there wont be any 4G icons in CM framework.
Also, make sure you aren't unzipping the new framework-res.apk you want to theme and flash, or trying to resign it. Only sign the flashable zip, not the individual files inside. The only thing you want to do with the framework-res.apk you will package and flash is open (not unzip) with 7-zip and navigate to the res/drawable-hdpi folder so you can drag and drop the new icons into it, overwriting the old.
I hope that helps!

How important is it to re-sign? I have modified the Framework and Resources apks with 7zip by switching images out. I have also modified the Rosie.apk. I put everything back where it was supposed to go, backed out of 7-zip and flashed. I have never had an issue with it, nor have I re-signed it. Just wondering.

AFAIK if you are on clockwork recovery, I don't think it checks for signatures. I think Amon_ra requires a signed file to flash. I think it's just added protection against flashing any old junk. If you can flash in amon_ra without a signature and you don't have problems then I wouldn't worry about it. It's the signature of the framework-res.apk ( or com.htc.resources.apk) that's important. That's why you don't unzip it.

I think that
1.7.0.2 = yes
1.8 = no

Thanks, any advice does help.
I did make sure the the icons I was swapping out were named the same thing in the CM ROM, but I didn't check the size of it at all.
I didn't unzip the famework-res.apk but instead just went into it with 7-Zip and dragged the icons into that. Then I backed out of 7-Zip so that it would save and close everything properly - know that does work because that is how I add the Fold transistions to the ROM - and then I put the famework-res.apk into the folder and zip it up per your instructions above. Then I manually sign it (still haven't been able to get the auto-signing to work) and then flash.
I'll have to try again moving a CM theme to the CM framework-res.apk and see if it is working. What I was attempting to do was take, from the Batman Theme for sense, the drop down notification shade with the Bat Icon and put it into the CM ROM. I don't know if you have time to try it yourself to see if it works, or if you get the same issues that I had.
Either way, thanks for the help! I know I'll get this theming down at some point!

Hey buddy.
I’m stuck. I had to download and install Eclipse with the sdk plus java. I don’t know where to go from there. Every time I open the rom that I want to theme and get the framework.apk and edit the PNG’s , how do I go about saving them? Do I just used the same name as the old ones or I have to save them with a new name.
Or pm Me.

So now you have an unzipped framewor-res.apk with a bunch of images. This framework should be the one that you want to take icons from. If not, start over with the ROM you want to copy images from. You will want to copy the images you want to put into another ROM so that you can dump them into the new framework-res.apk. After you figure out what icons you want to bring to your new framework, get a clean version of framework/com.htc from the ROM you are actually running - i.e. if you are running myn ROM on your phone, download the myn ROM and pull out the framework-res.apk or com.resources.apk that you are going to theme.
Now with this fresh clean framework you will "open" it with 7-zip to navigate to the /res/drawable-hdpi folder so you can now drag and drop the images you want to copy over into it. Then the close the 7zip window and your framework-res.apk is all set to flash. You don't need to rename if the file names are the same, you can just drag and drop and the files will be overwritten in the new framework.

[Reg Edit] Right click ApkTool

First things first, credit and thanks to Brut.all for his awesome tool.
Now then, i couldn't find anything like this so i've created a very simple little reg edit to enable right click de-compiling on apks and right click builds on folders.
I've been using it for a couple of weeks with no problems and it's great for those quick .9 or xml edits.
DISCLAIMER:
This was made for the Windows XP operating system! .so im not sure if it will work on other Window OS, feel free to try but im not responsible for your computers well being so use at your own risk.
EDIT:After a little research it seems the registry tree is the same for "Vista" and "7" so it should work on them also
To use this you must have apktool working correctly.
Only works if your path variable is set to C:\sdk\tools\
If your Path variable is set differently you have 2 options:
1-let me know where and i'll attatch appropiate reg-edit.
2-Easy option, create a folder on your C:\ named "sdk", inside the sdk folder create another folder named "tools,
now copy the contents from your original tools folder into your newly created tools and add the path in enviromental variables. Simple.
RECOMMENDED:
It is highly recommended to backup your registry prior to installing, just follow the simple instructions included in the download zip.
To install:
Simply extract .reg file from the folder, double click and answer yes.That's it
Now your ready to become a de-compiling/building whirlwind.
Useage
-I simply right click an apk, "empty.apk" for example, choose decompile (you recieve a folder with the apk's name), navigate into the res\drawable* folder and drop in my .9.png's.
-Backout of folder, right click "empty" folder and choose build.
-The built images are in are located in "empty\build\apk\res\drawable*".
-The built apk is located in "empty\dist".
I've included an empty.apk for quick .9.png edits, this saves hunting through endless amounts of images for your newly created .9.
If the tool fails it could be something simple-
Problem: solution:
-Folder already exits -Delete or rename
-.9.png's not properley edited -Fix using draw 9 tool
-Required framework not installed -Open cmd and type "apktool if FILE LOCATION\framework-res.apk"
Remember this is a simple tool, for more advanced useage and logs use apk-manager
Final Note:
If Brut.all has any reason for me to remove this please let me know and it will disappear ASAP.
Thank you.

Just extract and double click, it might say "cannot import all data", just ignore it, it will restore your create new folder option.

Haha, you win a prize of getting a thanks.

You have no idea how much I love those! When I get back to my computer I will give you one for this awesome little tool because I have never used apktool because of the command line. I always used apkmanager.

[WINDOWS] Rom Zip Modifier

Hi,
everytime I want to flash a new version of a rom I have to modify the zip file contents, i.e. delete some files etc, which is a very tedious process.
Thats why I created a little tool for Windows (requires .NET 3.5) that can do the following with a zip file of a rom:
- Delete files
- Add / Replace files
- extract .apk's, decompile them, modify (regex replace) inside text / xml files within, recompile them and put the updated version back into the rom zip.
The tool is still beta, so there could be many errors if you don't use it correctly... always make a copy of the rom zip before using this tool on it
The included apktool (for decompile/recompile of apk) requires JRE 1.6 and only works for Android Jellybean roms / framework-res.apk's - but I think you could just use another apktool version for different Android versions.
Included in the package is a sample configuration that is basically exactly what I am using. Of course you can change what files to add, delete and modify. Also there is a screenshot attached so you can see what it looks like - as you can see you need to have some basic knowledge of how android rom stuff works, I don't think this is useful to total noobs, sorry.
If you have any problems / suggestions feel free to write here.
I hope this is useful to someone
Regards
Abomb
Changelog:
1.0: Inital release
1.1: Some error checking, not all errors will be caught but at least some basic ones.
1.2: Files to delete and apk's to modify can now be selected from the zip file via file browser
1.3: Log during modify operation and bugfixes
1.4: More bugfixes, plus the settings are now stored in the image of a cat

Thanks I'll try it.

Nice tool mister.
There is any way to add zip paths auto (for example /system/etc/ etc) against to write all the line manual?
I'm using win7 and winrar.
Thanks.

Ah now I see what you mean.
I'll try to implement a way to "open" the rom zip file inside the tool to select files from it without having to type in the paths manually.
Edit: 1.2 now has that feature implemented, please try it and tell me if that works for you.

Version 1.3 shows a log during the modify operation and has various bugfixes.

How to create your own tw rom on your phone using root explorer

In this tutorial I will show you how to create your own T.W. rom using your GS3 and Root Explorer. There are many ways you can create a rom but not everyone has the time to sit at a computer every night. However, your phone is always on you and can find a few minutes here and there to create your own masterpiece.
For the sake of this tutorial, we will name our new rom "SLICK".
Here are a few things you will need...
1. The rom base from Scottsroms. I'm NOT talking about Cleanrom but the unmodified stock rooted rom.
2. Root Explorer.
3. Script Manager
4. Any mod you can flash or come up with on your own.
1. GET STARTED!
Download the base rom to your phones EXT-sdcard and extract it using Root Explorer. After it's extracted the new unziped rom will be located in /storage/sdcard0/SpeedSoftware/Extracted. The extracted rom is now your new base. At this point it would be a great idea to move it to your EXT-sdcard and create a new project folder for it and label the folder "Project SLICK". inside the folder is your rom. lets rename that rom "SLICK".
Lets open your new SLICK rom. You should have some folders...
BOOT IMAGE
DATA
META-INF
SYSTEM
3. THE SYSTEM FOLDER
/SYSTEM/APP
Most of your work will done in the System folder so lets open that up. This is the heart of your rom! There are many folders here but lets start with the app folder. This folder has every app installed in your rom. This is a good time to remove the bloat you don't want in your rom. Go ahead and delete the apk's you don't want or need.
/SYSTEM/BIN
Here you can speed up your system or make it more battery efficient by deleting things like "mpdecision" and things like that. Be careful what you delete though. In general you won't do much in here.
/SYSTEM/BUILD.PROP
Here you can change values or add values. The one value we are concerned with is "ro.build.display.id" This build property's value will be displayed in the end users settings menu under "about phone". So let's give this property the correct value "ro.build.display.id=SLICK ROM v1.0" The rest of the build properties you can do as you wish. Build.prop is simply a text file. You can use the text editor built into Root Explorer.
/SYSTEM/CSC
Open this file and you will see more files. Listed is "feature.xml". Here you can edit values for various items for texting and mms.
/SYSTEM/ETC
Here is where you will find a folder called "init.d". Located in this folder are various text files. The text files are scripts that are told to run when your phone boots. You can add or modify to the existing scripts or create a new text file.
So we went over a few of the basics of modding your new rom and molding it into something you can call your own but does it work??
4. TESTING YOUR NEW BASE.
So we have already modified our rom a considerable amount and should have a good solid base. Before we go any further we should really test things out first. If we did something wrong earlier we will at least have an idea where to look. So lets flash our new rom. Go to you EXT-sdcard and find our project folder. you should still have your SLICK file. Zip this file with Root Explorer. Make sure you have a good battery and a cool environment because it's going to take your GS3 about 30min of hard work to zip this file. When that is finally completed, flash your new rom located in /storage/sdcard0/SpeedSoftware/Archives. Flash it just like you would any other rom.
Test your new rom out on your GS3 and see how things are running. Check your existing modifications you did earlier. If everything looks good, we can continue modding. If not you will need to go back to your base to see where you went wrong. This is also a great time to check your init.d scripts. One way to do this is to download "Script manager" from the market and click on your init scripts to read there log. It will tell you if something went wrong.
If everything is looking good, we can continue modding...

5. THE MODS
So we have that nice clean base but what about all them mods in the roms we download and flash everyday? There are a few different ways we can do this and we will start with the easiest but first, do a nandroid backup of your new base. If one of your mods you perform next goes bad it's simply quicker to recover. Now, If you have flashable zips of some of the mods you like then you can flash them now and make sure they are working the way they should in your rom. Remember, just cause we have the d2vzw does not mean mods from the sprint or T-mobile won't work on our devices. Sometimes it's worth a try. It's all about which firmware they are on and what has changed with the firmware.
So we flashed a few mods but don't have everything we wanted. At this point you are left with only one option and that is to get on that PC of yours and learn to decompile a APK. I may touch on this subject later as it is a bit more involved for someone new to this sort of thing.
6. UNDERSTANDING THE FLASHABLE ZIP
The alternate method of a flashable zip is to extract your flashable using Root Explorer and picking it apart. For example we will use "Lean Kernel" and kill 2 topics with one stone. If you unzip the kernel you will see...
BOOT.IMG
META-INF
SYSTEM
As you can see there are some familiar files to us just like when we extracted our base rom in the beginning. Basically when you flash a mod like this or any flashable for that matter, it installs files into your rom in certain places. In this example we will be installing in BOOT.IMG and SYSTEM. But what? And what is that META-INF file for? Well this META-INF file is what tells your rom what files and what to do with those files. Inside META-INF is a text file called an "updater script".
Here is what it looks like...
Code:
show_progress(0.500000, 0);
mount("ext4", "EMMC", "/dev/block/mmcblk0p14", "/system");
package_extract_dir("system", "/system");
set_perm(0, 0, 0777, "/system/etc/init.d/00leanKernel");
unmount("/system");
assert(package_extract_file("boot.img", "/cache/boot.img"),
write_raw_image("/cache/boot.img", "/dev/block/mmcblk0p7"),
delete("/cache/boot.img"));
show_progress(0.100000, 0);
Line 2 shows it mounting the system so we can write to it.
Line 3 shows us extracting the entire directory of the system file in the flashable into the system file of our rom.
Line 4 shows we are setting permissions for one of the system files we just installed in the rom. In this case it is an INIT.D file.
Line 5 shows us returning the system to an un-writable state.
Line 6 shows we are now installing the other file called BOOT.IMG.
So we installed BOOT.IMG and the SYSTEM file. The BOOT.IMG file is usually only found in a rom or kernel zip so most of the time you won't see this file in a flashable but I wanted to use this as an example to show a bit about the kernel side of things.
Ok, so lets get back to the original files of this flashable zip. The updater script stated we installed a new system file into the rom so whats in there? If we open the SYSTEM file from our flashable with Root Explorer you will find a file hierarchy...
SYSTEM
-- ETC
--- INIT.D
---- "00LEANKERNEL"
-- LIB
--- MODULES
---- Listed here are a bunch of ".ko" modules and i'm not listing them all.
So whats the point of all this? Well lets say when we originally debloated our rom in the begining we could of included some of our flashable mods like a custom kernel before we zip the rom to test the base. So in this case we can manually install this kernel before we zip the base. We can take the BOOT.IMG from our extracted kernel and replace the BOOT.IMG in our extracted rom. We only need the files from the flashable so we need to copy and paste the "00LEANKERNEL" file from our flashable to our roms /system/etc/init.d folder. We can also take those ".ko" files from the flashable and dump those into the /system/lib/module folder and we are done. You have now manually installed a kernel into your base rom before you zipped it. Now when you zip your rom and flash it, your new base rom will boot with your custom kernel. Since we manually installed the kernel we don't need the META-INF file provides an auto install script for installing through recovery. Technically we could take all of our flashable mods, extract them, look at the file hierarchy and copy and paste the those files to our extracted base rom. That way we can zip our rom and test it with the mods right off the bat. You can really make things quicker this way and is in general the way to go.
I think it's rather important to fully understand a flashable zip. How it's built and how it completes it's task. It's used so often and makes mods so incredibly easy to install but it is also what installs our rom! One of the files we see when we open "slick" is a META-INF and there inside is the updater script to flash the rom. Again we are doing the same thing as we do with the flashable mod but this time we are installing a lot more files with a lot more permissions. It is the exact same thing as shown above just a bit more extensive.

7. PUT THE PIECES TOGETHER
Ok so we have our base rom running on our phone and possibly a few mods installed. We also have our extracted and debloated "slick" rom on the EXT-sdcard inside our project folder. The next part is rather easy if you understand how those flashable mods were installed. If you understand the whole flashable and its files, your better off just extracting them and then copy and paste them where they need to go. After you have all your mod files in place you can now zip your official "Slick" rom using Root Explorer of course. Prepare yourself for another 30 minutes for it to zip. After it's zipped your done. You have now created your first fully modded rom! However...
Lets say you don't get the whole flashable thing and or you had made some other changes to the rom while you were testing. Lets say you flashed some mods and created a few init.d scripts or the build.prop along the way. NO WORRIES! We can put the rom together another way. A lot of the mods you flash will install files in some usual areas of the rom like your Framework folder and such. Lets just say we don't know though. You can actually copy complete folders from the rom you are running right there and now and paste them into your extracted "Slick" base rom using Root Explorer. So you can take "/system/framework" from your currently running rom, copy it, and paste it in "/storage/EXT-sdcard/project folder/slick/system/framework". In short just take your copy of the framework file and put it in your extracted base and paste it. Root Explorer will then ask you if you want to replace this file and click yes. You have just transferred any modded file that might have been in framework to your extracted rom. Any folder you may think was modded, simply copy and paste it to your extracted base rom on your EXT-sdcard. Once you think you have it all the modded files transferred you can zip your new "Slick rom! Flash and enjoy!!

FINISHED
So we have now completed our own rom on the device itself. It's really not too difficult just a bit more time consuming with zipping and that. However, you may need to do a bit more research on how to decompile and recompile an APK. This is one of things that can really be a pain to setup. It's again the basics that will kill you. The whole PITA is not decompiling or making changes to a framework file, it's setting up the environment that sucked for me. You have to get the Java and files in order and all the little crap to get it to work. IMO, if you haven't decompiled an APK yet it's really not difficult at all. Like I said. It's the basics. I encourage you to learn this because it's so freakin easy after it's all setup and you will be able to do so much more with your rom. Once you get this APK thing down don't be afraid to take someone elses work and reverse engineer it. Try to figure out what that developer did to accomplish what he wanted. It's a great way to learn and thats what it's about.
I may add to this somewhere down the road but for now it's all I have. I hope this helped and motivated someone to create a rom and begin there journey to become developer someday! We can all use fresh ideas for development. There is so much more to come for Android so get your hands dirty and share!
Thanks guys!

Ha never really thought of doing this on the fly with my phone. Even though all the right stuff was sitting in my face thanks for opening my eyes razz1

It's another way. May not be the fastest way but it's another option. I also wanted to write this as a general rom creation and learning some basics. It's always the basics that will kill a project and motivation. I would like to see a complete newb to be able to complete a rom with this tutorial. Then I accomplished something. Going to have to finish this tomorrow though. It's taking longer than I thought lol.

Yea I mean I'm a newb at doing it from my phone if that counts =) .. What explorer do you like to use to repack the zips. I'm sure I'll try this method soon to play while bored at work. Rom tool box will help with boot animations, fonts and transition animations too take care thanks for giving our community some new skills I'm sure it will help out down the road.

Thank you for this post. This will definitely get me to try and make my own ROM the way I like, also I might just learn some new stuff. Great post thanks again

Nice tutorial.
It's a great way to show what can be done just from your phone.
:good:

Right on man. Been waiting for this. Thank you.

So would I make, say ROM manager a system app? Just copy the apk into the /System/App folder?

Yes, but not all apps you download from google play work in /system/app. Some want to be installed into /data/app. However /data/app doesn't exist till after the rom is booted. You would need to add the folder to your extracted rom and modify the updater script.

That's about all I have for now. OP completed!:sly:

Hello. Ok so I created a ROM what I call MyTWGE (Tuchwiz Google Edition). Followed the instructions, unzipped the stock Verizon OS went into the -app- folder deleted all the Verizon, Samsung and Google apps (only the ones that are download able from Google Play). Replaced the stock launcher with the 5x6 version that I extracted from another zip, replaced the camera with the Google edition camera (download able from GP), replaced the keyboard with the Note2 keyboard (also unzipped from another zip). Looked around and deleted a few more files I found that were connected to some Samsung apps and zipped it up. Flashed the zip yesterday onto the phone and it's ALIVE working.
Thank you for your patience to write up all these instructions. I previously used TB to debloat my phone and that was it, learned a few thing thanks again

Only thing that that's annoying is the wifi in the taskbar. I read in one of the posts that I have to go into systemui and some other files within n delete lines 12 through 21 but that didn't work , am guessing I need to decompile systemui to do that. The person in the post didn't clarify and I'm not ready to do that yet. Reason is I don't know anything about programming or linux or decompiler or anything like that. Deleting files I can do replacing some sure. But I'm happy my first attempt to mix something together worked and I'll keep doing it till I actually figure out what it is that I am doing. Thanks again for the post
