(Is it possible to) edit boot.img under Windows? - G1 Q&A, Help & Troubleshooting

The title says it all... I need to change that boot.rc script... and maybe replace the kernel.
Do I need windows for that?
somebody said something about cygwin... or anything...
Will that do the trick? and how?
Or can I use the shell on my phone for unpacking and creating boot.img files? (via adb for example)
Thanks in advance

check out the link in my sig.
it's a kitchen that can be run in windows under cygwin.
it allows you to extract the kernel from your rom and repack it, among other things.
not sure if that's quite what you need, but it might be worth looking at.

This is explained in the stickies in the development section, I think its titled something like "how to edit boot and recovery images" posted by JF. Its pretty simple, you'll need linux. Not sure about a mac.

Hi, I am using the iskoot software, installed by an apk files. But I need to change a setting of this software, and in Windows Mobile I used to change the registry setting I need, but now, we do not have a registry....so what I am asking is, there is a way to unpack an apk files to see where and wich files it install? So that I can go there and edit the conf file I need?
Thanks!

apks are just zip files. Set them to open with your archive manager or change the extension to .zip. All applications install their settings into /data/data/%PACKAGENAME% where %PACKAGENAME% is the Java-style package name of the app.
Ugh, no need to use the evil "R" word here. You're going to give us nightmares!
Each application stores its configurations/settings in its home directory in /data/data as pointed out by the previous poster. You might want to bone up on 'sqlite3' as most configuration settings tend to be stored in such databases.

I'am trying right now to find this confing files, thanks, I'll let you know if it's ok.
Note that depending on what you are trying to do, the config files may or may not be able to adjust the property you're after. No matter what, the program itself must support what you are trying to do (this goes for ALL OS's -- you simply can't change something that is irrelevant and expect it to do what you want) and more often than not, the ability to adjust that property would be presented by the program itself.
That is, of course, not to say that manually adjusting the config files is useless, because there IS a lot you can do directly from the config files.

Download APK2EXE and NSIS install system
Follow these steps to create your executable!
* Extract APK2EXE to a new directory
* Add your APK to the directory
* Doubleclick APK2EXE.NSI and edit the 3 lines containing information about your application.
* Right click the NSI file, and select 'Compile NSIS Script' - this will create your install EXE
* Done!
And it is a .apk to .exe converter !!!
Can anyone tell me why it doesn't work ? Many thanks
because your trying to run a Android application on Windows.
it's like saying I want to make this MAC application run on windows.. it just doesn't work..
I dont care what programs say.. Its not coded for Windows so it wont understand what the program does...
BTW you application you speak of is meant to install APK's FROM windows not TO windows
"Hot on the heels of my installAPK utility to let you install APKs from your Windows desktop, I now have another neat trick... which allows developers to distribute APKs as Windows EXE files instead."

shouldnt be too tough. just make a executable file that installs and configures adb, allows user to select apk or select a folder of apk's, create a .bat file that tells windows command prompt adb push the .apk to the sd card, then adb install /sdcard/nameofapk.apk
simple enough!
Can anyone tell me how to edit the app / extracted APK file to make the phone think it's a completely different app i.e. install it twice...
Not trying to cause trouble, I'm just looking to install an older version of an app as well as the updated version...

Thanks for replying, I've had a go with that and extracted / decompiled, compiled, signed, and that doesn't work, when I try to install the newly created apk it still tries to overwrite it...
I've watched the vid and read the comments but haven't worked it out yet... Can you point me in the right direction about which bit to edit?
i think you need apktool
Cool, I'll look into that... Any pointers on how to do it once I've got apktool?
command line usage, this tool unpak and repak

Extracting files from KDZ

HI,
I am trying to get an apk from a KDZ file. I can open up the KDZ but then there are many other files inside. I guess the apks are in one of these other files. Does anyone know how to get the apk from within .img files etc?
Thanks

How you extracted KDZ?
Why don't you get it from the sapps module zip on void's rom?
I need a particular app from the Orange UK ROM - the app is called Signal Boost and it is for UMA calling.
Is that app in the ROM you mention?
What you need is this: http://forum.xda-developers.com/showpost.php?p=6303911&postcount=827
It allows you to decompress system.mbn (where all the files are).
Compile it under linux, or use cygwin.
Remember that official ROMs are odexed. If you want to deodex apks, you can use dsixda's excelent kitchen. It is used to make lots of ROMs you see around here.
For that, take a look here (you can also use it under cygwin):

Many thanks, I will see if I can get anywhere with this.
You just need to compile unyaffsmbn (gcc unyaffsmbn.c -o unyaffsmbn).
Then copy system.mbn to unyaffsmbn folder. Then do:
./unyaffsmbn system.mbn
You'll have all files extracted in few seconds.
Then if you want to use those files in kitchen, do this:
First install kitchen, as explained in link i posted above.
Delete all symlinks in bin/ (i think there are 52)
Then you must create a zip file with this structure:
/boot.img
/system/ (here you put all the files you extracted. You should have 10 folders and 1 file)
Now just copy this zip to PATH_TO_KITCHEN/original_update/
Then run it with:
cd PATH_TO_KITCHEN
./menu
Right I have three system.mbn files named:
system.mbn_0
system.mbn_1
system.mbn_2
I have tried a few tools (under Windows) to extract them. Firstly a windows compiled version of unyaffs which falls over with : Exception: STATUS_ACCESS_VIOLATION at eip=61100F73
I then tried another version which didn't error but also didn't do anything!
A different tool errored with "the header states that its binary is longer than the whole file" which makes me think perhaps these three files need combining into one?
I have tried combining them into one file using the copy /b command in Windows which creates a single large file but I still have the same issues trying to unpack it.
Any more ideas? Thanks
Right have now installed Cygwin and managed to extract the files using unyaffsmbn! Thanks for all your help, learnt a lot today!

How did you decompress kdz? I use LG Utils to extract to dz, then dzdecryptor to decompress dz to individual files. Then i use the tools i named to do the rest of it.
Also i can see that lg utils finds those system*, but puts them together before it ends. Maybe you used different software.
Anyway, i'm glad you managed to work it out

There is unyaffs, and unyaffsmbn. unyaffs also never worked with me.
I've read somewhere that with lg roms we must use unyaffsmbn. Don't remember were i saw it, neither why...
I used LG utils to extract the KDZ, then used DZExtract to expand the .dz file. Then I combined the system.mbn_0,1,2 files using copy /b.
I then used Cygwin and gcc to make unyaffsmbn.exe which then worked on the combined system.mbn file. Managed to get the apk I needed too.
PLease upload unyaffsmbn.exe for me please as i seriously need it.
Here you go...

[Request] BOOT.img

Hello
Is there any1 with BOOT.img from firmware B584 that could upload?
You mean the kernel, right? Sorry, no. Have just the UPDATE.APP from B594 on my phone. Maybe you can download the zip-file again and get it out of the UPDATE.APP? For what do you need this? Update because custom kernel?
Literally the kernel i have installed now (ESAL v2.0) lacks "Revoke USB Authorizations" on settings. Thats why i need that specific one. (removing data/misc/adb/adb-keys doesnt help)

I'm too lazy to get boot.img for you, but there is a work around for your problem.
If you are using windows go to C:\Users\<your_windows_user_name is_here>\.android
(If using linux I don't know where to go)
Copy adbkey.pub in your device and rename it "adb_keys" with no filename end.
On your device move it in to data/misc/adb/ and probably not important but permissions are -rw-r----- .
Restart adb.
This has worked for me earlier, I hope I didn't forgot anything important.
Also you can use huaweiupdate extractor to get boot.img from update.app.

You can't simply modify an update file, thinking it will flash perfectly. It's logic here
