Does anyone have information or know the capabilities of the FM radio IC built in the HTC EVO series, do they use the same chip for all models, and are we exploiting all of its capabilities, like HD radio, etc. I see someone already has a hack for the HTC fm player that allows it to tune without an antenna/headphones. Nice, but I want more! if you have any info, i'll take whatever! Thanks!

TUTORIAL: Reverse engineering HTC FM Radio for noobs (on EVO 4G)
Okay, I'm writing this because I want to help any other newbies trying to learn how to reverse engineer. The technical details involved in this are extremely daunting, so the purpose of this tutorial is to first explain in layman terms exactly what you're trying to accomplish and what to expect. Then we'll go over the details. That way you're not completely blind going into this. I'm fairly new to the scene, so I'm not as knowledgeable as everyone else. If you see any errors in my post, let me know so I can change. I'm going to assume you know a little bit of Java, can find your way around a computer, and know nothing about Android. The techniques used should work with other Android phones. For this tutorial I'm using Windows 7, Cygwin, and my stock (not rooted) EVO 4G mobile phone.
The FM tuner for the Evo is run by a Broadcom chip: BCM4329. This chip is pretty amazing in that it does wireless, bluetooth, and it has an FM receiver/transmitter. We're interested in the FM receiver / transmitter.
Now, all android phones are based on a Linux kernel. Basically they're Linux running computers. The Android operating system is then installed onto the linux system. Every app is then run off of Android.
Android is based on Java but it is not a Java system. It uses a virtual machine called Dalvik. Google did this to get around licensing issues with Sun Microsystems. So they pretty much invented their own machine language (called byte code) for the Java language. This makes things complicated for the reverse engineer because from what I've read, once Java is converted into this machine language or byte code, it can't be converted back.
So let's rehash.
If you were programming strictly in Java, you would see these extensions:
Java source code = .java
Compiled Java source code = Java byte code = .class
Compressed file to package your program = .jar (Java Archive)
But since you're programming in Android and Dalvik, you will see these:
Java source code = .java
Compiled Java source code = Dalvik byte code = .dex
Compressed file to package your program = .apk
(I haven't mentioned this, but HTC further Optimizes their .dex code)
Optimized Dalvik byte code = .odex
I'm writing all of these down because it's very easy to get confused with all of the extensions. (for me at least!). remember how I said once you go dex, you can't go back to java? That's where JesusFreke comes in. He's a senior member of XDA, and he created "baksmali" and "smali", two programs that can convert the Dalvik code back into a human readable format. These files have extensions of .smali
Decompiled Dalvik byte code = .smali
But what can you do with .smali files? That's where this other senior member, brut.all comes in: He developed apktool. apktool takes JesusFreke's work to the next level. This program in conjunction with NetBeans, actually lets you trace through any program using the .smali code taken from JesusFreke's programs!
apktool does this by converting those .smali files into "fake" .java files that can be used by the NetBeans (program that compiles and makes java programs) IDE. I say "fake" because apktool embeds the .smali code into java files as comments. However, once you attach a debugger to NetBeans, you'll see that the debugger will follow line by line every execution statement found in the smali code!
So...... you can take the program you want, plug it into Net Beans using a debugger (using the default ddms command provided by Android SDK), and you can trace everything you do in the program. I have it connected to my phone, so whenever I push a button while running my HTC FMRadio app or unplug my headphones,I see the corresponding response to the HTCFMRadio code I have loaded in NetBeans. I can now see in real-time how the program operates from my own interactions... JAM.
Technical Aspects: How to get from ground zero to tracing HTCFMRadio?
1.) Download Android SDK - Go to google development site and follow instructions: Make sure to download the latest Java JDK. Once that is installed, download NetBeans 6.8. Unfortunately, smali debugging does not work with the lastest versions of NetBeans.
Download the "Java SE" version for minimal space
http://netbeans.org/downloads/6.8/index.html
You can follow the rest of Google walkthrough and download Eclipse and ADT plugin, but it's not pertinent to this. You're going to be using adb and ddms from the android SDK extensively, so make sure the path for </android SDK/tools> is included in the PATH variable in your ENVIRONMENT SETTINGS. To get here, right click My computer, click properties, Advanced Settings, ENVIRONMENT SETTINGS.
2.) Search for 7z and download it. It is an awesome and free compression tool that will be extremely useful. It can be used to "unzip" .jar, .apk, and other compressed formats.
3.) Get the Radio app. You can do this by going to "shipped-roms" website, downloading the latest Supersonic image, and following the directions in the unlockr tutorial for HTC kitchens at the unlockr website... (once you have extracted the files from the image, you can look in the system/app and system/framework directories to get the files listed below) or:
you can pull the following files from your phone:
Using the command prompt type (and with phone plugged in, and with USB debugging enabled on phone):
adb pull /system/app/HtcFMRadio.odex
adb pull /system/app/HtcFMRadio.apk
adb pull /system/framework ./framework
This will put HtcFMRadio.odex and HtcFMRadio.apk in the current directory and create a framework directory with more files. A couple of the files in the framework are needed for the HtcFMRadio app, but for simplicity, we're just going to pull the whole directory.
Now that we have the files, we have to make a few changes to make the app installable and to be viewable by the debugger. To do this we have to decompile the .odex format into a human readable format we can edit. That brings us to:
3.) Download baksmali and smali from Project Hosting on Google Code (google search smali).
Usually an Android application is made up of one file, an apk file. Inside the apk file is an AndroidManifest.xml file, a classes.dex file (compiled Java code for the program), and other folders. The other folders contain either graphics or other .xml files that tell the program how it should look to the user. We don't have to worry about those for now. This is important because APKTOOL only opens programs set up this way. But wait up? We didn't download one .apk file, we downloaded an .apk file and an .odex file! What gives? Well, if you right click the apk file and open it (using 7z), you'll see that it's missing the classes.dex file. The dex file for the app is actually the HtcFMRadio.odex file we downloaded. So, to make this system app more like a nominal app, we have to find a way to convert the HtcFMRadio.odex to a classes.dex file. That's easy with baksmali and smali!
Once you download goto command prompt and type:
java -jar baksmali-<version>.jar -d framework -x HtcFMRadio.odex
(Remember to match baksmali-<version>.jar with the filename of baksmali you downloaded)
If done correctly, you should see a newly created \out directory
This creates an out\com\htc\fm directory with many .smali files.
Now let's reverse the process and put it back as a dex file. Type at command prompt:
java -jar smali-<version>.jar out -o classes.dex
If done correctly you'll see a newly created classes.dex.
now, right click on HtcFMRadio.apk (select 7z and open). Drag classes.dex into the file. Say yes to the prompt. Now you have a normal apk file APKTOOL can read!
4.) Download APKTOOL from Project Hosting on Google Code and the helper apps for your OS. (If you're extracting files for windows OS you should have apktool.bat and aapt.exe). Extract (again using 7z, don't you love this program?) apktool.jar (keep it as a jar file, don't extract the stuff inside of it), apktool.bat, and aapt.exe to the directory you're working on. To make things neat, you can also delete HtcFMRadio.odex (you don't need it anymore) and classes.dex (make sure you put it in the HtcFMRadio.apk file first!)
If this is the first time you're using apktool, then you have to install the htc framework so apktool can baksmali the Radio app. You only have to do this once:
apktool if ./framework/com.htc.resources.apk
Alright, at the command prompt:
apktool d -d HtcFMRadio.apk
This extracts the contents of HtcFMRadio.apk and places them in the HtcFMRadio directory. However, there are two major differences between this content and the content created in step 3. If you go into the smali directory you'll see that instead of .smali files, you'll see .java files. And if you go back and edit the AndroidManifest.xml file, you will also see that it's in text! Android applications convert their xml files to binary format. Now that APKTOOL has converted everything to an IDE friendly format, we can use NetBeans to edit everything. The first thing we're going to do is edit AndroidManifest.xml (using notepad) and add the following:
android:debuggable="true" to the Application tag.
IT should now look like this:
<application android:theme="@android:style/Theme.Black.NoTitleBar" android:label="@string/fm_app_name" android:icon="@drawable/fm_radio" android:taskAffinity="android.task.fmradio" android:description="@string/htc_corp" android:allowTaskReparenting="true" android:debuggable="true">
This permission lets the debugger watch the program while it's running on the phone.
We are going to run into two problems if we try to install this program. One is that Android doesn't let you install more than one copy of a system app. The second issue is that if we change the signature of our system app, then we'll have to change the signatures of our other system apps as well! Ahh.... So, to get around that, we're going to trick Android into thinking we have a completely new program. We're going to do that by renaming the com.htc.fm class to com.htc.modradio class. Next step:
5.) Cygwin (or Linux virtual machine)
The easiest way that I can think of to replace strings in multiple files is by using linux. You can most definitely do it in WIndows, but I dont know how. If you let me know how, I can put it in this tutorial.
(update: you can use Notepad++ to easily find/replace strings in multiple files for Windows. You still, however, want to download Cygwin if you're going to develop with Android-NDK.)
For now, just search for Cygwin (Cygwin is a program that lets you run Linux commands from a command prompt using your Windows directories), and install it. Make sure to have the Perl option selected. You'll need Perl to make the following commands work.
Once you get Cygwin up and running
cd <to your HtcFMRadio directory>
in my case it's
cd /cygdrive/c/Users/Jerry/Desktop/HtcFMRadio
now type the following commands in this order:
this command changes all occurances of htc/fm to htc/modradio in your xml and .java files.
find ./ -type f | xargs perl -pi -e 's/htc\/fm/htc\/modradio/g'
this command changes all occurances of htc.fm to htc.modradio
find ./ -type f | xargs perl -pi -e 's/htc.fm/htc.modradio/g'
If you don't follow this order, your source code will get messed up.
If using cygwin, a bunch of .bak files will be created. Using windows search, find all .bak files in your HtcFMRadio directory, then select them all and delete them (Make sure they are only files with .bak!)
Now just rename the fm directory to modradio. It is located in HtcFMRadio/smali/com/htc
Now go to your windows command prompt and type:
apktool b -d .\HtcFMRadio modradio.apk
Now sign and install modradio.apk on your phone.
adb install modradio.apk
If you have never signed before, then you need to use keytool and jarsigner. These two files are in your JDK directory, so make sure you include your JDK directory in the PATH variable of your ENVIRONMENT SETTINGS. (To get here, right click on My Computer, click Properties, Advanced Settings, Environment Variables. Once you make change, open up a new COMMAND prompt to see changes).
cd to the directory which has modradio.apk
now type:
keytool -genkeypair
Answer all questions, then use the same password for all password prompts.
Next type:
jarsigner -verbose modradio.apk mykey
Type in the password you created in the above step. Your apk should now be signed.
Next install:
adb install modradio.apk
Success!
6.) Testing the app on phone
Go to your phone and you'll now see a new FMRadio icon next to your first. Click on it and watch it open. It should now be able to play music. Keep it open.
7.) Using Netbeans
Go into HtcFMRadio and delete the build directory created by APKTOOL.
Now open up Net Beans and click on File, New Project, Select Java Project with Existing Sources, click on Next
Select HtcFMRadio directory for Project Folder, rename Project Name to whatever you want. Let's type in ModRadio. click on Next
Next to "Source Package Folders" click on "Add Folder" and select the smali directory.
Click Finish. For a quick tutorial by Brut.all, search APKTOOL in youtube and click on: Apktool Demo 2 - Smali improvements
Right click on Libraries. Click on "Add Jar / Folder". You want to add Android.Jar. Since I have Android 2.1 loaded I went to /platforms/android-7 located in my android SDK directory.
Your project is now ready for editting!
8.) Running the Debugger to trace through program.
Next go back to Windows command prompt and type ddms. This runs the Dalvik Debug Monitor. A window should open up. In the left hand side you should see com.htc.modradio. That's our app! To the right you're going to see 2 numbers, you're interested in the one to the right, 4 cells away from com.htc.modradio. This number is a port number, and you're going to use it to communicate with NetBeans. (In my case it is 8603)
Go back to NetBeans and click on Debug, Attach Debugger.
In the host field type: localhost
In the Port field: type in the second number you saw. (8603)
If everything is working you'll see a bug appear next to com.htc.modradio in the Dalvik Debug Monitor. Look at the bottom bar of NetBeans for feedback. If you get errors make sure the numbers match, or try port 8700 and make sure you select com.htc.modradio in the Dalvik Debug Monitor. Port 8700 is the default port used for whatever program you select in Dalvik Debug Monitor.
9.) Setting a breakpoint
I'm making this a seperate step because it is completely arbitrary. When creating a break point be sure to follow this rule:
You must select line with some instruction, you can't set breakpoint on lines starting with ".", ":" or "#".
Rather than looking for a spot to breakpoint, though, I'll tell you where to put one so you can quickly see how the debugger traces through the code. You aren't "REQUIRED" to do the next step, but if you want to trace you have to put a breakpoint somewhere.
In Net Beans click on the Project tab, click on Source Packages, com.htc.modradio, and then doubleclick on BroadcomFMTuner.java
We're going to insert a breakpoint. Scroll down to line 3226 and on your keyboard press: CTRL-SHIFT-F8, select line in dropdown box and hit ok. (To keep it simple, I usually look for "invoke" instructions to set breakpoints at)
Now go to your phone and click on the physical "back" button on your phone. This will clear the radio,(you should still be able to listen to music). Drag your status bar down. You should see a radio icon. Click on it again. The radio backgroudn will appear, but you wont' see any text or anything. Now go back to your netbeans application. You should now see debug options highlighted! Click on Step Over (F8) to step through!
Great work on other HTC phones, not sure it applies here...
Sounds like HTC uses an all in one bluetooth/fm radio chipset... possibly broadcom, this fella has gotten somewhere!

APP:17FEB10:RDS FM Radio R&D: Get radio text, Alt Freqency, free TMC etc
Microsoft hasn't defined a tuner API for Windows Mobile platform (yet) and manufactures such as HTC do not publish their API for FM radio.
GFMAPI is an FM Radio interface that designed to be used on different models of Windows Mobile devices.
It makes all FM RDS based applications such as Radio players, Radio Alarm, TMC navigation works on different devices.
What's new?
Download EtenTest and GFMAPI 1.0.
Currently it works with M900 and M800, tested with PowerRadio and hyperGPS.
This is for Eten/Acer devices only.
End-User and application developers (Downloads)
User should try to use the GFMAPI in the application package because it may need to signed with privileged certificate and version of interface may be different.
App Developers can find FMAPI.h and a test application APITest in the GFMAPI for HTC devices 1.6. Source code is included to help your development.
The interface is defined in C language with sample code.
Thank for NetRipper made a .Net CF library for GFMAPI.
Note: the latest FMAPI.h is in GFMAK and the GFMAPI will be updated. They only has minor differences.
Supported Devices
* BRF6350 Chipset:
HTC Diamond, HTC Raphael (not CDMA), HTC Blackstone, HTC Polaris, HTC Topaz, SE Xperia X1
NOTE: if your X1 has new media panel that integrated with FM Radio function, you may have to disable this panel (I don't know how).
Download GFMAPI for HTC devices 1.6
* BCM432x Chipset:
HTC Rhodium, HTC Leo, HTC Mega
Supports radio functions if renaming FMSDKWrapper.dll to FMS_API.dll with the above driver. RDS data cannot be received.
We are working on this device. Related thread: FM Transmitter on HD2
* SI470X Chipset:
HTC Artemis: NOT supported.
Samsung Omnia: Samsung i9x0 Omnia
Samsung Omnia II: GFMAPI.dll for Omnia II and its Cab format This is an excellent work done by phjz.
Eten/Glofiish/Acer M800/M900/V900/X900/X650/S200: see "what's new". Please help me test it.
Device adaption developers
Generic FMAPI Adaption Kit will help you implement the driver for your device. Use APITest in the GFMAPI to test your driver.
Please read readme.txt in the package. Feel free to ask me if you need help.
If you have a device that is not supported by GFMAPI
I currently only have a HTC Raphael so I need your help to get your device supported.
First of all, you should Search in this Thread to check anybody posted it before.
Extract FM radio related files and upload to the forum.
Note: You cannot simply copy files from/to device. You need dump the ROM then extract files from the ROM. Search this forum to find how.
If you have good VC++ and IDA pro with ARM skills, please join us to discover FM Tuner API on those devices then make RDS application working on your device.

Far far away from any progress and not many users.
BBCBBA uploaded FM radio related file for Gigabyte GSmart S1200. This device supports RDS by using deviceIoControl directly communicating with the driver. I can see it is possible to make a GFMAPI driver just need a lot of effort.
Applications based on GFMAPI
* FM TMC driver for navigation: Beember's HyperGPS.
* A powerful RDS FM Radio application: 6Fg8's Power Radio
This project focuses on RDS API now. TMC related topic has been moved to the TMC thread because it is too attractive and posts will flood the thread.
Origin research project
Many people ask questions related to FM radio in the forum have been solved by this project:
* Does FM Radio supports RDS text and traffic information?
* Does FM Radio supports more than 20 saved channels and give a friendly alias, such as "BB Radio 4" rather than 920.2MHz ?
* Does FM Radio supports automatically or manually change frequency when signal getting pool during traveling?
* Does FM Radio support RDS-TMC traffic information for navigation system?
The answer is yes. The Bluetooth/FM radio chip BRF6350 on your phone is very powerful but HTC FM radio only provides basic functionality.
Unfortunately HTC doesn't publish FM Service API to us.
So I disassembled FM player by using IDA pro and know usages of FMS api.
After a week sleepless night, I wrote my FM radio tool, xFMRadio, utilizes most functions provided by FMS API, provides RDS and other data for further research.
With help from this thread, we have exposed most secret of FM and RDS system on HTC devices and we can make useful applications now.
This application is written for research so that UI is not nice. It only works on BRF6350 based HTC devices.
Download xFM Radio v0.4
If doesn't have sound on your device, try xFM Radio v0.4B, which removed audio volume initialization.
Brief user guide for xFMRadio
Default settings: Audio Source: 1 (earphone), RDS =1, Verbose =1, AF = 1. ( but I don't know if automatic AF is working. have to verify during long distance traveling.)
Verbose: 0 -no log; 1 - status only; 2 - TMC raw data; 3 - all types of log
Row 1: Input argument. Set Frequency in KHz, AF list: alternative frequencies for the current station.
Row 2: Frequency, station name, Band: World/Japan - use this to listen police station etc
Row 3: Signal Strength, Stereo/Mono, UTC Date/Time (update once per min if supported)
Row 4: -100KHz, Previous Channel, Next Channel, +100Hz, Mute, Mono/Stereo
Row 5: Headset/Speaker, De-emphasis, Stereo blend
Row 6: Radio Text
Row 7: status such as Music/Speech, TP, TA, PTY, TMC etc
Check if the channel support TMC: ROW 7 should display [TMC]. You can see TMC data by setting the top left input box to 2, and click on Menu->Verbose.
The current xFMRadio v0.4 does not display RDS raw data anymore.
You can use Save log menu to save log data.
FMS API version is displayed in the About dialog. Mine is 1.2.
xFMRadio 1.4 Debug...
it does not support HD radio.
Solved...
Fair enough... I was getting that impression anyhow, especially with the lack of responses. One could only dream that with all the digital aspects of modern comunication (bluetooth, cell, etc), that they would throw in HD digital FM along side it... but as I can see, this only fits in well with every other aspect of modern lackluster industrial corporate innovation. Peace out!

I have a Linux server running at my home that I use mostly for file storage among other things (like an Asterisk PBX). I keep ALL of my code on my server so that I can get to it from anywhere. That being said, I use MinGW32CE (part of the CeGCC Cross Compiler) to compile my native apps. So since I can build my apps on my Linux server, I wanted to figure out how to build the CAB installer on the server ... And here it is:
Install WINE
Download the Microsoft Cabinet Software Development Kit
Download CABWIZ (Its included in QuickCAB). Copy CABWIZ.EXE and CABWIZ.DDF to a new folder.
Extract MAKECAB.EXE from cabsdk.exe, rename it to all lower case and put it in the same folder
Create your cabwiz INF file (See MSDN CABWIZ Information File). For SourceDisksNames path, use .
Run CABWIZ using the following syntax: wine cabwiz.exe appname.inf /compress

OK, So I've gotten to breaking down and recompiling those pesky .dex files, but I've run into a new problem.
This is a noob question, I'm sure, but .so files look like unformatted, binary files. How do I open then, edit them, etc? I need to read whats going on in my libs. :-(
Are these X11? I'm running ubuntu 10.04 x64 - so those could be difficult.
ie - unreliable 64 bit support.

They're native library files, so platform specific machine code I imagine. Look for an ARM disassembler. I'm not familiar with linux internals, so don't know how you find the entry points, but it obviously will be widely documented. Is it impossible to obtain the source code? Assuming most are written in C/C++, reverse engineering from the machine code is not something I'd describe as a pleasant experience. If the source was well written assembly language & not too big, it can be almost enjoyable I guess. But then TBH walking through a randomly selected programmer's source, let alone object, files scares me, in a Tim Burton inspired bad trip kinda way. If you can find the source, it will be an order of magnitude less painful.
Try IDA Decompiler, it should disassemble all so files!
Most of the libs are open source in the aosp. Some are proprietary blobs with the only solution to them being reverse engineering.
.so disassembly
i know how to disassemble it
you will need orion's easy apk disassembler and apk manager
i've tested it once and it worked, but there´s a problem, i dont know how to re-assemble
1- rename the file .so to .apk like "libtestlib.so" to "libtestlib.apk"
2- put in the folder "place-apk-here-for-modding" of apk manager
3- open script.bat (or something like this) from Apk manager
4- use extract apk option
in the beggining my images inside the lib was corrupted so i used step 5 to fix
5- use option optimise images inside to fix images
6- go to project folder and copy classes.dex file to the root of easy apk disassembler's folder
7- open EasyApkDisassembler.EN.bat and use the "DISASSEMBLY a classes.dex with smali" option
8- give a name to the folder (like "libtestlib")
9- it will create a folder (like "out_libtestlib") with the disassembled files

Basically I want to be able to decompile apks. And jar files directly on my phone. Can I do that?
Yes, you can. At least, for the most part. The main constraining factor is the small amount of memory available on the device.
1. run the dx util on baksmali.jar, to produce a classes.dex file
2. add the classes.dex file to a new jar (or you can just add it to baksmali.jar)
3. push the jar containing classes.dex to the device somewhere (let's say /data/local/baksmali.jar)
4. dalvikvm -classpath /data/local/baksmali.jar org.jf.baksmali.baksmali <normal baksmali options>
5. bonus points if you then proceded to run baksmali on baksmali.jar (and then the universe implodes)
note: I just tried this with the latest version of baksmali, and there's some weird issue with the baksmali jar file, where it contains duplicate entries of every class file, which causes dx to choke on it. I'll see if I can get that fixed soon, and get a new build out. In the meantime, you can probably find an older version without that problem.
Sweet, thanks for your input. I was out last night and I had this idea for an edit to make, only to become sad because I didn't have access to a computer.
This will help me out a lot.

The problem seems to be within the buildprocess as the generated classes for baksmali and smali are added twice to the *-dev-jar-with-dependencies.jar. As I'm not familar with maven I didn't fixed the source of the error but I managed to get it working.
I attached a small pythonscript which is able to remove the dublicated files within the jar. Just run it over the file and get a fixed version which is processable by dx.
The script:
Code:
#!/usr/bin/python
import sys
from zipfile import *
if len(sys.argv) != 3:
print("Usage: %s input.jar output.jar" % sys.argv[0]);
sys.exit(-1)
input = ZipFile(sys.argv[1], "r")
output = ZipFile(sys.argv[2], "w")
seen = []
for file in input.namelist():
if file not in seen:
output.writestr(file, input.read(file))
seen.append(file)
else:
print("dub found: %s" % file)
input.close()
output.close()
sorry ...

1. run the dx util on baksmali.jar, to produce a classes.dex file
2. add the classes.dex file to a new jar (or you can just add it to baksmali.jar)
3. push the jar containing classes.dex to the device somewhere (let's say /data/local/baksmali.jar)
4. dalvikvm -classpath /data/local/baksmali.jar org.jf.baksmali.baksmali <normal baksmali options>
5. bonus points if you then proceded to run baksmali on baksmali.jar (and then the universe implodes)
note: I just tried this with the latest version of baksmali, and there's some weird issue with the baksmali jar file, where it contains duplicate entries of every class file, which causes dx to choke on it. I'll see if I can get that fixed soon, and get a new build out. In the meantime, you can probably find an older version without that problem.

I realize this is a very old thread, but it is exactly what I am looking for However, it seems there are Java 8 features in smali/baksmali now and dx does not work. Is there a workaround for this or any other way to run smali/baksmali from terminal on Android? Thanks!
The older versions of smali may still work for you. Or what I've done is use Termux and download the jdk for arm64 and used the ndk to compile smali on my device.

Thanks for the reply
However, I am not trying to compile smali on my device. I am trying to run the latest smali/baksmali on my device in Termux. Unfortunately, the older versions will not work for my needs. If you can help I would really appreciate it
But compiling the latest build of small on the device will allow you to use the latest build of smali.
Well, at least one is interested and dared to ask, so here it comes:
an old style batch file kitchen
that only deals with application add/remove
has a fixed XIP
and a fixed OS Version
and it cannot dump an existing ROM
If you want to port another OS Version you are on your own, no support in the kitchen, neither for SYS nor for XIP. So basically it is just an end-user "cook your meal" kitchen with fixed ingredients and not a whole chef cuisine.
The folder with all the files you need (and one ready cooked ROM if you want to try that first) is located at mediafire.
It has the same ingredients as my Tornado kitchen (which is based on that of NitroGenious). The OEM parts are picked from the ROMs that exist already and all of these are largely identical in that part. Some special treatment was done in these ROMs on the backlight and the battery driver. You may wish to find the differences yourself - I picked the backlight driver that best fits my needs. Some more changes to the Tornado Kitchen are (as far I remember):
The batch file handling is not caring any longer where you unpack the kitchen, it can work anywhere in the path.
replaced G'reloc (that was not regularly run) with WMreloc that now runs at each build on the dump folder, so you can basically do whatever you like also on the modules part, wmreloc will align the memory slots always in an optimal way.
The template (source) BINFS is now minimized and there are two flavors of it, one with LZX and another with XPR compression. Just copy either one over the 82040000.bin file. The used imgfsfromdump.exe could also take this from the commandline but I like copying files more than editing the batch file.
almost all parts dealing with WIFI have been removed, the ones that are left in the kitchen will do no harm.
Please also see my post on the shortcomings of the Hurricane compared to the Tornado when announcing the kitchen.
You may also want to learn some basics about Windows Mobile to arm yourself for what you intend, have a look at my Beginners Guide to Windows Mobile (prepare for cooking)
So what to do to get ready cooking?
SuperCID your device -> look in the Tornado Kitchen thread where the process of getting that done is explicitly described. Please take special care about backing up the files from that process! Skip that if you did it already.
Put the patched SPL 1.00.100 on the device. This will allow the BIN file to upload correctly later and it will enable your device to get charged from any USB charger. Skip that if you did it already.
Unpack the kitchen to any folder that you like. It should be a dedicated folder for just that purpose but it can be on any disk and at any place in the directory tree (not too deep to stay below the 255 char path limit, I suspect).
(you start from here for subsequent cooking) Run the batch "BuildOS-all-steps.bat" and follow the instructions that the batch file writes to the command window.
After building the ROM is done (XPR builds much faster than LZX but makes 20% bigger ROM files), you find the result in \Flash as OS.BIN
in \Flash you run as.exe and kill active sync (you may have to push the kill button twice)
connect your device in bootloader mode with UI = yes
run mtty and select the "USB" button
press enter to see the command prompt
enter "info 2" (no quotes)
You must read "HTC CuperCID" at the end of the information to continue (step 1. did that)
(you can skip that for subsequent cooking) Now you can load the OS.BIN to the device. Note that there is a handy feature in MTTY to save you from typing the whole path of the OS.BIN over and over again:
Push the "F" Button (3 from right)
enter "l" (no quotes) for the "download" command
enter the full path to the OS.BIN file in the "first time downloaded file name" field
leave the rest as is
Confirm
Push the "1" botton (second from right) and see the action start
You should see progress per loaded block of the BIN file until it is finished loading to RAM. It then takes as much time to load the RAM copy to the ROM onboard the device - this is the crucial part - be patient until the command prompt comes back.
Enter "ResetDevice"
Close the Terminal window in MTTY (Ctrl-F4 or Ctrl-W) - you can keep MTTY open - to avoid the USB polling for the no more connected device to eat all your CPU.
Wait for the device to start up. This will take some minutes - and if you activate the option "Startup and Shutdown Sounds + Animation" you should see the HTC Boot animation after ~30 seconds. Then you will notice that the screen turns white after some time, don't bother. With the red button you get the normal content back. It may happen during that time of first boot that you feel "locked" out of the device - just wait until the screen gets a little "dim" and press the red botton then.
After you passed the initial Welcome screens the device is ready to use. Reboot is very fast (40-50 seconds) and memory is plenty (35MB RAM).
Finally you may want to check out the German localization (100% for all settings and OS parts) or the nice home-screen that I have added.
Thanks to sniper304, a replacement for the ddi.dll is available in the shared folder at mediafire. Replace the content of "<your-kitchenpath>\WORK\OEM\OEMDrivers\ddi.dll" with the archive content. This removes the scrollbar quirk after a new cooking cycle.
reserved for even more future updates
Thank you!!!
P.S. Hello again!I have a problem with kitchen.
An error no file msvcr71.dll. I copied it from the internet but all the kitchen so as not working!
or
4 Make OS.nb
Very emergence \ OUT
and did'n make ROM.

You try to copy the files msvcr71.dll to Windows \ system32 direktoris and don't forget to install the Visiual Studio Redistributable Package 2008( requirment of windows to run C++ Programs) on your own computer
Thanks to all!!!Kitchen is working!!!Z have add russian language to my hurricane!!!!
Tobbbie THANKS!!!It's good!
I have not created a file OS.nb.
In order to create, I removed from BuildOS-all-steps.bat line
IF EXIST% kitchenpath% \ OUT (rd / s / q% kitchenpath% \ OUT)
And only then works!
Tobbbie THANKS!!!
hacking or cracking an android app is a easy part with XDA AUTO TOOL ..
search and download and install this tool ..
Process
Step One – Decompiling The APK File
Open the xdaAutoTool folder and run the program. It will prompt you to install a file called “framework-res.apk.” Ignore this. Close the program.
In the xdaAutoTool folder you we see a bunch of folders appear after the program ran. Look for one called “_INPUT_APK.” Put your APK file in the folder and run the program again. Press “Decompile All” located on the left side of the program window.
xdaAutoTool will decompile the APK file and create a new directory in the _INPUT_APK folder.
Step Two – Finding Your Target
Are you ready to be introduced to Smali code? Don’t worry! It isn’t too difficult once you realize what’s going on in the code. Java can’t be decompiled back into the original source code, it can, however, be decompiled into something called Smali code.
Navigate back to the _INPUT_APK directory and open the new folder (it will have the same name as the APK file). Once there, you will see a directory named “smali.” This is your target. Depending on your intentions, you will need to sift through the various files and folders in the smali directory until you locate the code you would like to modify.
For example, if you are trying to increase the firepower of a turret in an Android game, you will need to find the file for that turret. These directories are structured. You will probably see quite a few directories containing files used for advertisements, etc. One you discover the actual game directory, everything you need to alter will be in there.
How to change smalli code
now again open xda auto tool after edit changes and recompile and build your changes
You done ..........
