I have Android Revolution HD, and already installed a few custom mods like lockscreen, weather etc.
My question: How can I remove just a single mod? I can use the restore option but I don't want to backup each time I install a mod.
Thanks.
Anybody knows?

you have a couple of options:
1. you find out what files the mod changes and make a copy of the old ones first
or
2. have the person that created the mod make a flashable un-mod zip
3rd option is for you to make your own un-mod flashable zip

I think I can only do the first one. IDK how to make un-mod flashable zip.
Unfortunately mod files may change some very important files on your phone. Without opening the mod and seeing what files are changed there is not much more you can do. So if you still have the mod you can use (well I use) winrar to see the files that are involved with the mod. Then pull those files from your original ROM and overwrite the modded files using an app like Root Explorer. This may only work in some cases.
Another way is to take that mod you have and replace the files in it with the default files and use it to restore back.
The best advice I can give you is always take the time to do a NAND backup before installing any mod in the future.
If you have a previous NAND backup you could restore it and take your losses with what you have done from that point till now.
[TUT] How to extract .ftf file to make custom rom - Flashable ZIP [2012 Xperia]
This tutorial is for developers who want to make their own custom rom based on official firmware. OK, let's start.
Explanations:
Inside every flashable zip file there are two folders - system and META-INF:
1) system folder - That is actually your ROM and all it's content (If you ROOT your device you gain access to this folder in your device).
2) META-INF folder - That folder gives instructions to your device (ClockWorkMod) how to flash ROM, sets permissions...
This is method to get Stock/Official system folder that you need to edit to make custom ROM.
You will need to find/make yourself contents of META-INF folder - You may took it from another ROM and (maybe) edit.
NOTE: If you use this method your ROM will work for both Locked/Unlocked bootloaders, and it will require that you have firmware your ROM is based on already installed before flashing.

How to get contents of stock/official system folder - Extract .ftf file:
1. Download .ftf file for your device.
2. Extract .ftf file using 7Zip.
3. You will get system.sin and other files. You only need system.sin file so delete others.
4. Open flashtool and inside flashtool open SIN Editor to dump data from system.sin - you will get an ext4 file.
5. Open ext2Read and extract ext4 file.
6. Done.

How to put CWM into your ROM:
OK, Now you ask - Why do I have to put CWM into ROM? Let's explain:
CWM is custom recovery that you use to flash zip files to your device. There are two types of CWM:
1. For both Locked and Unlocked bootloaders - Recovery is in the system folder of the ROM.
2. Only for Unlocked bootloaders - Recovery is somewhhere else (You don't need that).
Because your ROM is based on official firmware it will be for both Locked/Unlocked bootloaders.
Therefore, you will flash your ROM in CWM for both Locked/Unlocked bootloaders.
And if you flash you will replace system folder of previous ROM. Because CWM was in that folder of previous ROM - You will lose CWM.
That is why you need to put CWM.
----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
1. Find CWM for both bootloaders for your device.
1. Copy sh file inside files folder to system/xbin.
2. Copy other files inside files folder to system/bin.
3. Go to META-INF/com/google/android/ and you will find updater-script.
4. Add the following lines to it
Code:
set_perm(0, 0, 0755, "/system/bin/recovery.tar");
set_perm(0, 0, 0755, "/system/bin/battery_charging");
set_perm(0, 0, 0755, "/system/bin/battery_charging_help");
set_perm(0, 0, 0755, "/system/xbin/sh");
Thanks srl3gx for tutorial.

How to add ROOT into your ROM:
Want your custom rom to be rooted? Here is how:
1. First you need to choose from two great root management apps: Superuser (choose ARM one) and SuperSU(I prefer SuperSU).
2. Download zip file.
3. Go to "system" folder in downloaded zip and copy files within their folders to its place in your rom (same directory - if was "app" then copy in "app".
4. Edit updater-script to set correct permissions - Find that on someone elses rom, it should look just like for CWM, but for those files.
5. Done.

Click to collapse
Useful notes:
1. Don't edit any file in zip with Windows Notepad or else you will get an error in CWM - you need Notepad++.
2. When you put system and META-INF folders into zip set compression to - Store.

[TUT] How to extract .ftf file to make custom rom - flashable ZIP [2012 Xperia]
This tutorial is for developers who want to make their own custom rom based on official firmware. Note that as of 2012 our Xperias use ext4 file system so other tutorials won't work.
Inside every flashable zip file there are two folders - system and META-INF...System folder is ROM content...and META-INF gives instructions to CWM how to flash ROM Content....This is method to get contents of SYSTEM folder, you must find META-INF yourself....
1. Download .ftf file for your device.
2. Extract .ftf file using 7Zip.
3. You will get system.sin and other files..You only need system.sin file so delete others...
4. Open flashtool and inside flashtool open SIN Editor to dump data from system.sin - you will get an ext4 file.
5. Open ext2Read and extract ext4 file...
6. Done...you will get contents of system folder that you need to modify...
7. IMPORTANT - When you later make zip choose compression - Store
PS: Don't edit files with Windows Notepad or else you will get an error in CWM - you need Notepad++...
Maybe later I will make Screenshots

any idea on how I can edit boot.img? the one used for this device are different from what I know.. I am trying dual boot..
you can pack and repack boot img with Android kitchen i think
Great tut
Sent from my Xperia Tipo using xda app-developers app pro
I already knew this method. However I congratulate you for your initiative. :highfive:
Well I learned something else. Before it only used to extract some files. I did not know we could do this way the custom roms.
I'll try to make a custom rom.
However verified that the file size of system.ext4 is 665,654 KB. Once extracted using ext2read, is only 467 MB.
It is normal for this situation? Instead of decreasing, should not increase after extracted?
Kind regards,

That was my problem too I ended up with an ext2read error and less size
But ext4 is Linux system partition and not zip file. Maybe flashtool made partition that big so every file could go there easily and it couldn't set exact size.
There is no other tool on internet, only ext2read.

OK, don't forget to add CWM and root into your ROM. Actually I will rewrite my post in few days.
OK, the tutorial is rewritten. But it is not done. I will finish the rest later.
i did these steps[even without adding CWM ,just making a flashable stock rom(not included cwm) from cwm] ,but while want to install zip (my custome rom) from recovery ,installation after 2 seconds facing with error("installation aborted")
what is it's reason?
thanks

oh understood!!
i want to combine your tutorial and this thread
to make a rooted and included cwm custom rom
so i used from "META-INF folder and ROOTING files" that presented on that thread
i think this is my fault!
is it right?
thanks

I understand now.
First that zip should only make use to you to learn a little bit more about development. To install that you need already to be rooted with CWM installed.
Second it doesn't install because our devices use a little bit different things. Edit and change every MTD to EMMC and every yaffs (or similar) to ext4. (Notepad ++)

Yes, Iv'e done this before.
1. Rename the .ftf to .zip and extract system.sin with winrar.
2. Get program Called Internals Linux Reader.
3. With Flashtool use the option extract data from sin and select system.sin and extract data.
4. With Internals Linux Reader Mount Image and Copy everything inside the image to a folder.
5. Go into folder and highlight everything and right click and press add to archive (WINRAR!!!!!!!)
6. CHOOSE ZIP AND DONE THERE YOU GO!
NOTE - YOU DONT HAVE META-INF FOLDER SO YOU WONT BE ABLE TO FLASH!

Hi guys, I was able to extract system.new.dat from a rom (purity lollipop) and now I have the old good system with folders, so I can change whatever I want. But I tried to flash the zip and only the boot.img gets installed, the rest seems to be ignored.. What should I change in the zip on order to get it to install correctly?

Can I use the updater from the same rom but kitkat version? The things I install are the same I think..
From CM Gapps page it says
It is possible to perform a "backup" of the Google Apps on your device and then "restore" them, but this does take additional steps which are not covered here.

I'd like to know how can I do this.
I've searched all across the forum but had no luck. It looks like some kind of trade secret.
I know that it's not just a matter of pulling the apk files. Because I can see that the zip has .apk, .jars, .so, configuration and certificate files.
I'm guessing this is done by extracting the files from a system.img.
But how is this done?
Is there some script available to build a gapps zip from a system.img file?
Another thing is that my OnePlus phone doesn't has an official LP update yet (although CM12 and their gapps work fine) so I suspect this would have to be done using the stock ROM of another device, maybe a Nexus. Is this correct?
Any help is appreciated.
Thanks
