[Q] Flashable zip - T-Mobile LG G2x

If I have a flashable zip file, like a custom rom. Can I simply extract it with windows zip utility, and then create another archive (zip) again the same way? Are there specific custom settings that I would need to set in order for it to be flashable within clockwork recovery?

Anyone up to creating a flashable zip?

If anyone can create a zip that is flashable for CWM of the following that would be great! I am trying to disable the built in limitation that only allows SIP calls over wifi when using the standard dialer.
http://forum.xda-developers.com/showthread.php?t=1354838
Place it in an existing theme or flashable zip and delete whateva is in the zip in the correct folder and edit the meta inf to add different directories if needed but if its just an apk place it in the app file of the zip. I would help mate but I'm not on my pc.
Hope that makes sense?

[TUT] How to extract .ftf file to make custom rom - and few tips [2012 Xperia]

[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.

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

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")

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 ++)

[Q] Can I just flash a new boot animation through TWRP

So I am running CROMI and I want to try some different boot animations. I found a few of them embedded in the ROM zip as zip files themselves. Can I just extract these to a directory and install the directly through TWRP? If not, are there any custom boot animation out there that can be flashed?
Thanks
Jeff

Even easier, just copy the bootanimation.zip you want into /data/local.

Try the ROM Toolbox Lite app. You need your phone to be rooted (a custom ROM will have your phone already rooted for you), and this app makes it a breeze to install a new boot animation. The app has a collection of boot animations ready to install, or you can make your own and use this app to install it.

How to make cwm flashable zips on phone

Want to know how to make CWM flashable zips using phone? Here's what you have to do. I have attached a sample zip file which consists of two folders viz. META-INF and system. Now download PowerGrasp.apk from the attached files. Install it, open it and then copy any app which you want as a flashable file. And then paste it in a new folder named "app" under the "system" folder in the "sample CWM.zip" file. Now the compressor of PowerGrasp will pop up. Set the compression level to 6. Now compress it. And you're done.
Now you've successfully made your own cwm flashable zip file. Use CWM recovery to flash.
{Neither of the attached files is my development. I got these files from a friend and posted these to help others who want to make flashable zips on phone}

Unpack system.new.dat

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?
