Can someone devedioise it & put it into simple terms?

Wow great work!
Though I wish the videos had higher quality (720p) so it would be clearer, but I wont complain since it seems that you put much effort in this

Interesting... is this what Doc, Darky, Webstar and other rom modders do ?

That's Awesome

Definitely worth a subscription!

Only 1 question: how to optimize png's??

Thanks for the awesome work.

With this materials available, one can start exploring and dissecting the rfs files.
Go ahead and try, it's Christmas anyway...
If I can, I will try to answer questions here. I'm no expert but I can try.

Thank you Nokia7Vista-this is GREAT present for Xmas

very very thank bro hihi oh my god

Now my second try to point out an obvious mistake that obviously nobody else noticed: If you overwrite the whole META-INF folder with the one of a theme, you could upload the theme in the first place as this folder contains the updater-script.
@OP: Can you please upload your update.zip so that we can see if it works?
OT: It's very interesting that your posts get moved to a troll thread if you point out a mistake.

[Q] APK Decompiling

I can't find twframework.apk to finish decompiling. Where is this file located?

I thought tw was touch wiz ?
I know framework-res.apk is in system/framework.

Oh I didn't know that... I was reading a guide on how to decompile an apk and it said to extract it. I tried running apktool without it but I just get an error.

Use a program called apk manager. It has the apktool already built in and it works flawlessly. Thats what I use for all my theming and editing of apks.

[Q] ROM port

Okay I followed http://forum.xda-developers.com/showthread.php?t=1598713
Trying to port a ROM but since I am fairly new to this I need some help.
Where to find the kernel?
What to do to the updater-script
And what to do with the build.prop
Please post help instead of posting that I shouldn't try this, I want to learn and help the gio community.

1. kernel. use the one from cm7 for a rom based on cm7, a custom kernel for stock roms for a stock based rom
2 build.prop edit any device names to gt-s5660 except the fingerprint parse release..... copy and paste that piece into the build.prop from a gio rom, its also in the guide
3 change updaterscripts asserts device checking, format and mount values and delete permissions that dont excist
4 dont do this if you dont know how to port.
5 never post any rom before testing yourself. we dont want devices getting bricked by stupid people that call themselve a developer

The problem with this is, he was following a tutorial to learn how to port
Anyway, I think Voetbalremco covered everything. Try to start with port from ace or something, those are prolly the most easy to port.
Also, you can always port a rom which has been ported before. That way you can compare your own port with the working port and check if you're doing it right.

porting from ace is nothing, just copy some folders and editing a bit of "text" files..

Yep, most important: test by yourself, and ask it when u don't understand something, that's how you learn the most

All ports need to be either edited framework to match your Device or replaced framework to match your Device.
When you have done this, you can call it a Pure Port.

I'M NOT RESPONSIBLE FOR ANY BRICK I'M JUST SHARING
This RLE is for those who wants custom splash on their beloved ACE.
Enjoy! This file is made by me. Haven't tested, I don't dare repacking boot.img
Rename *whatever* (#) .rle to COOPER.rle and put onto root folder.

EDIT: The Apple's got a white line on top, will fix later maybe because Flickr doesn't allow any copy-paste so I screenied it.

For making or putting it into ace?

1.) Grab a png file.
2.) Use the converter by DoomLoRD.
3.)

adb shell

Never heard of this "clear" before! Try installing cygwin again, and on the package selection window search for clear. Otherwise, I really don't know what is wrong.

[WIP][XPOSED]Trying to find a Lollipop FIX

Hi guys, like you know xposed for Android 5 on our device break some system app like LGCover and LGWeather. This because the new Xposed use some binary built from the AOSP source that don't work with the above apks that contain an encrypted classes.dex ( AES128-CBC ).
Since decrypt that classes is quite impossible i started a different approach. So i looked inside the dalvik-cache where all the dex built by the compiler are stored.
Theese classes contains also the original classes.dex code.
example: /data/dalvik-cache/arm/[email protected] @....dex
Structure:
USELESS CODE
CLASSES.DEX ( that start with the magic dex.035 )
USELESS CODE
Header of the classes.dex
Offset.............Size...........Description
0x0................8................'Magic' value: "dex\n009\0"
0x8................4................Checksum
0xC...............20...............SHA-1 Signature
0x20..............4................Length of file in bytes ( in Little endian and hex value )
....
Getting that class is quite simple when you know how the dex header is formatted so i cut off the useless code and got the original classes.dex that can be decompiled with baksmali and used inside the apk.
Unfortunately this method doesn't work for the dex that were encrypted. Or at least, I'm missing the last step because there's something wrong with the code in this extrapolated class since the SHA1 signature appears to be wrong and consecutively also the Checksum are incorrect.
So, from my point of view we have 2 possible scenario:
1- the length of the classes that we can find in the header is wrong; ( most probable for me )
2- the code of the dex has been changed by the system.
Wish you can suggest me some ideas.
@suljo94 @P_Toti pls check this and tell me what you think. Tnx.

could you check if an system service is activated when the lgcover apk is called(to decrypt), if not the key might be saved in the app source code (might be obfuscated)

so I found a system service that gets called when the lgsmartcover app crashes to many times. the system restarts it together with lgcover. it is part of lgcover so I am hopping lg was so stupid to save the key in the same file as the encrypted container

try to look into the classes dex with an hex editor, it's encrypted and that's why you can't use tool like that on the original dex.
If you want play, this is the dex i extracted from the dalvik-cache of the LGweather apk:

so I got the slides and I am starting to think that the problem could be that xposed links app_process32 to app_process32_xposed and that the shared library gets injected into the wrong file (app_process32)
