I have modified the android system source file audiomanager.java for my own purposes and compiled the whole ROM. However, i dont want to flash the whole ROM. Which file is audiomanager.java compiled to?
Its location in the source is /frameworks/base/media/java/android/media/audiomanager.java
Thanks!
I have a working Kernel - http://forum.xda-developers.com/attachment.php?attachmentid=1743802&d=1361298599
but I need prepare a new one - compilation it is no problem, but how to prepare img file for taht?.
I heard that this is a Rockchip kernel image file - so I am a looking for information how to build this kind of kernel?
Procesor is RK3066.

If that is a zImage, then you need to pack it into boot.img in order to flash.
There are many boot.img tools out there which can help you. But the thing is you will be needing your device's original boot.img (Which can be extracted from your device depending upon the partition) which contains the Ramdisk in order to be successful.

In fact it is a regular (no gziped) image not a zImage. The file after unpacking from RK3066 format starts with bytes d3 f0 21 (to unpack I'm using rkutils ).
But I don't understand why we need to make boot.img with this file and only after that, upload boot.img to the device. Normally it should be possible just to upload kernel.img to the partition where kernel is stored, no?
After kernel from the link above is uploaded to this partition, the device boots up without problem. But when we compile new kernel and upload it (after converting with rk-tools ) it is not even possible to boot the device.
Any idea what's going on? Is compiling a kernel, then converting to rk3066 format is enough ?

Ok, I just had a look at your link and yes, it contains the kernel.img file. So it should be the kernel image file which needs to be flashed. What you actually needed to do is, unpack that kernel image using the tools of your choice and you'll get the ramdisk, zImage etc when unpacking. If you have compiled kernel from Sources, then you need to replace the zImage with yours (Found in arch/arm/boot) if your compilation was successful without errors and repack it to form the kernel.img.
But that doesn't mean it should boot compulsorily, it may not boot depending upon various weird reasons. You may have to fix it by yourself. Nearest bet is using your device's config file (Found in /proc/config.gz) and use that to compile your kernel. You can find all infos regarding what I've mentioned in this thread:

Some Basic things u need to Know before Porting
The rom which you want to port for your device is named here as PORT
The rom which is already working for your device is called here as BASE
First unpack system.new.dat in both port and base rom
For Ubuntu
Now we need to decompress .dat to ext4 img
Open terminal and
Now enter this command
./sdat2img.py system.transfer.list system.new.dat system.img
By running this command u can see a system.img
decompress ext4 img to output folder
Now we will mount system.img
Enter this command
sudo mount -t ext4 -o loop system.img output/
Now go to output folder and now u can see all folder and apk like a KitKat rom
Now do the same with port rom
Click to expand...

For windows use System Extractor for unpacking
1. Delete app,font,framework,media and priv-apps in base rom
2. Copy app,font, framework,media and priv-apps from port to base
3. Copy handheld_core_hardware.xml and platform.xml in system/etc/permissions from port to base
4. Copy 00banner in system/etc/init.d from port to base
5. Now open build.prop in both base and port for editing rom version and other things.It is different in different roms. For CM edit
ro.cm.version=
ro.cm.releasetype=
ro.modversion=
ro.cmlegal.url=
ro.cm.display.version=
ro.config.notification_sound=
ro.config.alarm_alert=
ro.config.ringtone=
Note: You have copy the above lines from port to base. Don't forget to add your device name in place of port rom's device name
6. Copy these files in system/lib from port to base I repeat from port to base
libandroid_runtime.so
libandroid_servers.so
libmedia_jni.so
For AOSP based ROMs other library files are also needed for boot up. For example Dirty Unicorn needs
libgui.so
libsurfaceflinger.so
libsurfaceflinger_ddmconnection.so
libwifi-service.so
If you are porting a 64 bit ROM copy these files in system/lib64 too from port to base
7. Unpack boot.img of both base and port rom and open init.environ.rc in ramdisk. Copy and replace all the lines starting from "bootclasspath" from port rom's environ.rc to base rom's environ.rc and repack boot.img . Use Android Image Kitchen for unpacking and repacking boot.img
8.Now we need to compress the base rom
For Ubuntu
Now enter this command
./make_ext4fs -T 0 -S file_contexts -l 1073741824 -a system system_new.img output/
Now u can see ur system_new.img
now we need to compress it back to .dat
Now enter command
./rimg2sdat my_new_system.img
Now u can see system.new.dat
Click to expand...
Click to collapse
For Windows, System Extractor has an option to repack but it causes bootloop for me. Ignore step 8 if it causes bootloop
NOTE: You'll need a different updater script for unpacked system
9. Zip it back and Flash
Downloads
sdat2img.py
make_ext4fs
rimg2sdat
Now Download all these tools and paste it to ur base and port rom directory then follow instructions to port lollipop roms

How to fix bootloop
Some Roms may not boot even after doing everything correctly. This method should be only used when nothing works
1. Copy all the files in system/lib, and system/lib64 if it's a 64 bit ROM, from port to base except the these files and folders
drm
hw
modules
soundfx
libGLES_trace.so
libGLESv1_CM.so
libGLESv2.so
libGLESv3.so
I repeat you have to leave the above files and folders and copy all the other files in system/lib from port to base.
If it still doesn't boot follow the second method
2. Unpack boot.img of both base and port, enter ramdisk and copy these files from port rom's ramdisk to base rom's ramdisk
seapp_contexts
sepolicy
service_contexts
Repack boot.img and flash it
IMPORTANT: This method should only be used when nothing works and if it boots after copying all the lib files, you will have to figure out which lib files are causing bootloop because port rom libraries will create many bugs.

thanks for releasing the guide
Thanks for the tutorial!
Tried porting slim6 from redmi 2 but got stuck on bootanimation forever.What Im I supposed to do with the build.prop?
I already tried
-not touching it
-replacing it
-replacing some things
all ended in just bootanimation :/ I use the nexus 6.0 rom for base
BTW should I replace kernel(zimage) in boot.img(havent done it)?
Whenv i try to repack the system folder to system.new.dat with the Extractor for Windows i always get the following error: "It seems like the extractor not worked with your provided system folder please contact me for help".
I have read that specially the CM roms give this error but i cannoy understand how to fix it even after search the solution.
The rom i was trying to port is a CM12.1 rom. Anyone knows how to solve this?

Yes it does exist for windows. And if it still doesn't work ask this in system extractor thread

I have just tried it but still the same issue.
I saw that the dev of the system extractor tried to explain how to solve the issue but honestly i don't undestand nothing of the process he's talking about, i was completely confused. For example, for some reason he was talking about the updater-script but i don't understand what relation are between what i want to do (repack the system folder) and the updater-script (located in the meta-inf folder).
Not booting, porting same vendor ROM but different model similar specs
Followed your tutorial till the last solution but no luck. I am trying to port my own device ROM but of a different model. I have Qiku Q Terra 808, model CP8692_I02 with 360 OS v21 and was trying to port v109 360 OS of model CP8692. The specs and everything is same however I am still unable to boot. There was a very weird thing happened when I flashed the ported ROM and restored the backed up data before booting. The device booted but it reboots on it's own in less than a min of booting and the cycle goes on. And if don't restore the data it goes in bootloop right away. I get the display on, optimizing apps then reboots and cycle goes on. The 360 OS are known for security and the device has fingerprint scanner. Do you think the stored fingerprint is causing issue in flashing new ROM or incorrect update script is the culprit?? Please advise.
@mshoaib7 Awesome tutorial man...??
CM14 theme engine has not been integrated at present, many functions is still in the invalid state, would you be interested in transplantation AOSP 7.1?
Very good ?A great help ?Moto g 2015

Hi all. I have a question regarding to the propietary files (vendor blobs source) of my device, which is a Huawei Mediapad T1 10 T1-A21w (codename "hwt1a21") with a msm8916 chipset and Android 4.4.2 (EMUI 3.0).
This device has absolutely zero development, so i had to create a (functional?) device tree, and fortunately i have the kernel source from the Huawei website but the only problem i'm facing now is related to the vendor blobs files, which i cannot get them.
I tried to follow many guides about this but i didn't find any of them that explain how to extract the propietary files from a device connected to adb and extract them with a script (extract-files.sh i think it was called) instead of download them from existing blobs files in a github repo.
I've being following the CM guide (this one) in order to create and extract the device tree and vendor files but i struggled in the vendor files process, in which supposedly i should have the extract-files.sh script and the most important, the propietary-files.txt which indicates which specific vendor files must be extracted by the extract-files.sh script. So that's the problem, i have no idea how i supposedly should get that txt file with the specific vendor files to be extracted from my device.
Hope someone can help with this, i've been months trying to bring development for this device.
Hello buddy i have the exact same situation as yours. Did you find a way out? My device has zero development. Made tree and kernel source. Could you please help?
Up ? need help too
Vendor files are located either in /system/vendor or /vendor. If location is /system/vendor then device must be rooted and /system/vendor must be mounted as read-write to access it's content via ADB.
Hello everyone,
I am currently developing with AOSP 5.1 for a FriendlyARM s5p4418 (NanoPi2).
Our special firmware is working nice, building it creates all the necessary img files (boot.img, system.img, userdata.img, ...).
But when I do a "make dist", it is not copying the boot.img into the IMAGES/ folder in out/dist/ folder. So when I try to continue, I cannot create a ota-package because the releasetools/ota_from_target_files crashes when trying to calculate the Difference of recovery-Image and boot-Image. Both are of type NONE because they are not existing.
Why is it creating the boot.img when using just make, but not creating or using it with make disk.
Is it because I am using the prebuilt kernel zImage?
Is there a way to fix this? Or to create an OTA package from the files that make creates?
Greetings
Tobi
Well it seems I found the problem.
The device tree is setting TARGET_NO_KERNEL to true, because it is using a prebuilt kernel uImage.
I did now set this to false and copied the uImage to $(PRODUCT_OUT)/kernel and now it is compiliing a recovery and the boot also.
But I do not know if this is the correct way to do it?
