[Q]Need Android Gurus - Issues

Hi to everybody, I come from the BADA subforum, and there is a new project trying to port Android to samsung Wave phone.
Devs have some issues, we are in the last steps and here is a summary
will want to note that the kernel has been confirmed as able to boot into android homescreen when flashed though JTAG
we're modifying the init scripts to boot it from sdcard
the device is accessible from adb how ever the Android system services such as zygote are restart looping
i *think* i managed to execute standard boot on init.rc with adb interface, zygote and android services appear to be stuck in a restart loop:
http://code.google.com/p/badadroid/source/detail?r=192
EDIT: would like to note that while "VIBETONZ" is appearing on the log, the phone is not vibrating, nothing is appearing on the display either. If possible i'd like a check on my kernel sources Oleg. EDIT AGAIN: the phone does actually vibrate, my bad
line 3150ish you can see the zygote service and various others getting killed and restarting.
EDIT2: another debug log extracted using "adb bugreport" (very large, will want to download in order to view)
http://code.google.com/p/badadroid/source/detail?r=193
http://badadroid.googlecode.com/svn/trunk/adb logs/bugreportnb190511.log
EDIT3: it's possible that the restart loop is caused by lack of memory, this could be caused by the memory mapping of the current bootloader we're using, will have to ask rebellos and srg about that.
added a log to googlecode for procedure to boot kernel using init.rc with adb interface working ( i'm not exactly sure why this works) i may upload the zImage i'm using for this, but it'll only work if you partition your memory card in the correct layout and format.

hi to everybody

need help, please!

anybody?

I will take a look later on this evening and see if I can tell anything.

Your kernel seems to work, most of your issues in the log that was posted in my thread come from the ramdisk and system build. Until you work at those for a bit, I don't think you're going to know where to place the blame for issues until you're clean.
For the VM crash loop:
Take all of the non critical apps and gapps out of /system/apps (stuff like vending, maps, touchwiz and so on.)
And see what you get. If you can't solve it that way, then try to do:
adb pull /dbdata/databases/com.android.providers.settings/settings.db settings.db
And see what you get. If its there, it's corrupt. If it isn't, check to make sure the directory is getting created. You can also get someone to pull settings.db from a similar device (i9000?) and try to push it to yours.
But that's only the first of your problems. You have some bad lines in init.rc (your rild daemon isn't configured correctly amongst other things), and a few things missing in /system/bin and /system/lib (calls to missing things). If you aren't using an extract of system.img from the sdk, you probably should. Then you can load in libs one at a time in a clean and controlled environment.
BTW: What Android system are you using? What device did it come from? If you built it from source, seriously, try using an emulator image first.

It is possible it was not made clear, its a 2.2 stock ROM being ported from the Samsung Galaxy S to the Samsung Wave (formerly a BadaOS device). It is also being booted off of SD as apposed to OneNand. It uses a patched version of the SBL from the galaxy S but when Android is flashed to Nand it can boot fine (although problems are had initializing the Modem).

You need to compare logs from system booted from nand and from sd. Whatever errors are the same don't matter. Its the different ones that will tell you more.
But you're crashing right now because some line of code somewhere in your build is looking for a database and can't find it. If it doesn't do that when installed to nand, then your problem is that directories that the system creates to host configs and module parts aren't getting created at boot.
The modem issue, (if the error in logcat is the same whether the system booted or not, haven't seen both) looks to be a radio interface layer problem, your rild daemon isn't loading (check /system/bin/ for "rild") and make sure the line in init rc that starts it is correct.

It's a strange problem, as using the extracted system.img from the Android emulator as filesystem the above error disappears - with the same kernel/initramfs/init.rc (obviously other errors appear but the services seems to be stable).
I think we can forget the ril related errors now (I commented out the service in my build together with the DR daemon) as we have no modem driver yet ...

[MOD]Epic 4G Dual Boot Support -- NOW WITH APP!!!

Dual Boot Support
DualBoot Helper APP is now on the market! (See bottom of this post for more info)
DISCLAIMER: I am not responsible for anything, ever. It is not my fault if you do not read. I do not explain things because I enjoy banging on the keyboard. If you do not read this entire post before jumping in then do not expect me or anyone else to be much help. By following this guide and any links YOU assume all responsibility for your device and anything that happens with it.
What is it?
Dual booting allows you to run two separate roms on your device at one time. It is done by intercepting the mount points during the startup of the device. This is accomplished by checking the sdcard for a specifically named file when the kernel first loads and uses the appropriate files to boot with the correct partitions. Reading from the sdcard is slower than reading from the internal memory of the phone so the speed of your sdcard will drastically determine the speed any rom runs. On the same note a rom flashed to the sdcard will take longer than usual on the first boot.
What does it do for me?
Running two separate roms has many uses for just about everyone. Users can use dual booting to try different roms, themes, apps, modifications, or anything while keeping their existing installation intact. The uses are just about endless. Besides testing different roms, this allows the user try these things and make sure they are compatible and stable before pushing the changes to their internal memory. Rom developers have all of the above options plus a few. Rom developers can additionally use dual booting to test builds of their roms without fear of soft bricking their device. For advanced users, you can mount the partitions of the other rom (be it sdcard or internal) and fix bad apk files or messed up files. The options really are limitless!
What do I need?
Sdcard 2GB or larger
Dual boot compatible kernel
Other things I should know...
*The kernel MUST support BOTH roms you flash. Unfortunately this means you can NOT mix froyo and gingerbread roms. Make sure you know what the kernel supports before you flash anything!
*If you compare roms, benchmarks will hold no value due to the sdcard being so much slower than internal memory.
*Faster sdcards will perform better than slower ones. Note: the stock 16GB sdcard is a class 2 which simply classifies it's minimum speed. A higher class sdcard will more than likely perform faster but the class rating is a minimum and not a maximum. It is entirely possible that a certain class 2 card can out perform a different class 6 card. Keep this in mind when researching to buy a new faster sdcard. More info in this post.
*First boot takes longer than usual. Up to 15 minutes! Please wait until the rom boots and the initial media scanner is done before you judge usability.
*Using a rom from the sdcard will cause the sdcard to wear faster. This is due to many more reads and writes of data than normal. The Epic simply does not have the internal capacity to run dual roms on the NAND. That being said the sdcard is our next option. While it may reduce the over all life of the sdcard keep in mind there are other android devices like the Nook Color and the other Galaxy S phones that have internal sdcards running the Android operating system. My personal opinion with is with other devices running off internal sdcards and with the price of sdcards getting cheaper and cheaper it was worth it to explore this option for the Epic.
Ok ok, so how do I get started?
I am going to break the steps down into sections. Please read everything to ensure you understand what all is involved in getting everything working. I recommend making a backup in Clockwork Mod and saving it to your PC before you even get started.
Section 1 - Setting up the environment
Step 1. Flash a compatible kernel (Kernel developers, PM me if you add my dual boot support to your kernel and I will update the list below) Remember you can NOT mix a eclair, froyo, or gingerbread roms and the kernel MUST support both roms!
Currently compatible kernels:
Genocide 2.0 Supported Roms: EC05, EB13, and DK28
Section 2 - Preparing sdcard
Important information!!!! This will destroy ALL data on your sdcard so if you lose pictures of your dog, cwm backups, nudies of your spouse, etc then you can't blame me. BACKUP YOUR SDCARD!
The easy way:
Reboot into recovery mode with a program like Rom Manager, Quick Boot, or type 'reboot recovery' from a terminal. (NOT 3-finger boot to recovery...this will NOT work)
The easy way WILL erase your sdcard with NO confirmation....you have been warned!
Choose one of the following flashable zips to automatically partition your sdcard
DualBoot_Partition_RFS.zip
DualBoot_Partition_EXT4.zip
The manual way:
Reboot into recovery mode with a program like Rom Manager, Quick Boot, or type 'adb reboot recovery' from a command line. (adb commands assume you have a working install of the Android SDK)
While in recovery issue the following commands:
Code:
adb shell
cd /sbin
./dbpart.sh --help
I put many hours into the partitioning script to make it as simple to use as possible. Simply follow program usage instructions.
Section 3 - Preparing a rom
Since we have blank partitions on the sdcard we need to populate them with data. There are multiple ways to accomplish this and you can choose which solution best suits your needs. I am not going to cover ALL methods here but enough to suffice any likely scenario needed.
The dd method will clone your current setup to the sdcard (these commands may take up to 15 minutes)
The easy way:
Flash this dd script: DualBoot_Clone_to_sdcard.zip
The manual way:
Code:
adb shell
dd if=/dev/block/stl9 of=/dev/block/mmcblk0p2
dd if=/dev/block/stl10 of=/dev/block/mmcblk0p3
dd if=/dev/block/stl11 of=/dev/block/mmcblk0p4
Preparation is complete. Please skip down to booting from sdcard.
The flash method is for flashing a new rom to the sdcard.
The easy way:
There is no sure fire easy way just yet. Stay tuned though.
The manual way:
This method is not that difficult so there is no need to be intimidated by it. It requires editing a few lines of the script that Clockwork Mod executes when flashing a rom or addon. For this example I am going to use a file named epicrom.zip but you can use any name you wish.
Step 1. On your PC, open epicrom.zip (I recommend using a program like 7zip)
Step 2. Navigate to the META_INF\com\google\android\ folder.
Step 3. Drag the file updater-script out of the zip to your desktop.
Step 4. Open the updater-script file with a text editor such as notepad (I recommend notepad++ or textpad)
Step 5. Change every instance of /dev/block/stl9 to /dev/block/mmcblk0p2
Step 6. Change every instance of /dev/block/stl10 to /dev/block/mmcblk0p3
Step 7. Change every instance of /dev/block/stl11 to /dev/block/mmcblk0p4
Step 8. Delete the entire line for any lines that contain /dev/block/bml7 or /dev/block/stl7 to disable flashing another kernel and breaking dual boot support.
Step 9. Save the file and drag and drop it back into epicrom.zip and let it replace the old one.
Note: If you get a status 6 or some other error when trying to flash it is likely you made a typo or your text editor did no save the updater-script file correctly. Recommended action is to correct the typo and/or use one of the recommended text editors note in Step 4.
Section 4 - Flashing to sdcard
Flashing a rom from this point is the same as you usually do. Put the modified rom on your sdcard and flash with Clockwork Mod like usual. I recommend doing a backup in Clockwork Mod BEFORE you flash in case you messed anything up by accident and end up flashing over internal memory when you meant to flash to the sdcard.
Section 5 - Booting sdcard
To boot from the sdcard place a file in the root of your sdcard called 'bootsdcard'. If you named it correctly upon reboot, the kernel will load the rom from the sdcard and not internal memory.
To boot back into internal memory simply remove this file from your sdcard and reboot.
You can switch back and forth using this method. If the file is there it boots sdcard, if the file is not there it boots normally. Pretty simple right?
Section 6 - Other flashables (not roms)
Themes, addons, and anything else that is flashable with Clockwork Mod must be modified in the same fashion as the rom. Use the same procedure documented in Section 3, The flash method.
Kernel Developers:
If you would like to add dual boot support to your kernel please refer to this commit: https://github.com/Rodderik/Genocide-Kernel/commit/a5dfd9f369ae4f2c90c1e7fc7d8995f88f72bd01
I will update this section if I push any specific changes to dual booting.
Now with an APP!
DualBoot Helper
VenumX coded up an APK to work with Clockwork Mod to run the scripts.

Just what I was thinking.

Tested on EC05 just now. I uhh... likey? =)
to bad no multi android versions though =(
why cant the kernel read off the sdcard? do you need drivers from samsung once again?

well the kernel is stored in bml7 and called by sbl/param during boot so unless we can get a bootloader to intercept the initial loading of the kernel and pass it off we are stuck with one kernel at a time

Very Nice Work !!!

Hey rodd... I think you should work on an aosp gingerbread kernel ... this is a great advancement in devlopment man... right when it was slowing again

this is amazing, thanks for this!!

You cannot make a cross OS kernel. We cannot integrate this into GB yet because there is no GB source, no GB source, no custom kernel. This is Froyo only, and well, someone else can make an eclair only kernel, but that is stupid.

How to Port a ROM to Milestone2

As lately some people are asking me about ROM porting I decided to create this new thread where we can share knowledge about this hard task.
Please note this is a Dev talk thread, so DON'T ASK about fixing a particular ROM problem here. Also don't ask questions like "My phone is bricked! please help!". This IS NOT the appropriate place for it. There are plenty of other threads to help you out.
Also note that this is not a step by step guide (and not a guide at all), it's just a point where you can start from. Android is a very complex system and there are many things I don't know yet. So, research and hard work is what you need to learn it deeply. My first tip is Google really works. Don't be afraid to search
Ok, to the basics. Porting a ROM is no simple task. It requires advanced understanding of how android works and how it is organized. Previous Linux/Unix knowledge helps A LOT. As android is based on this O.S. there are many similarities between both. In fact many ppl consider android to be a kind of linux distro.
The very first task to port a ROM is finding a device which is compatible with your own. For example Defy/Milestone2. Then you are going to choose a ROM to port to your device.
As our devices (Milestone2) have a locked bootloader we now need to find a system image that have a compatible kernel with the ROM we are trying to port. This is mainly based on trial and test and takes a long time. You'll be ending flashing your phone several times with RSD Lite. You should learn how to use MotoAndroidDepacker and how to create a fixed SBF.
The basic procedure to try that:
1. Open original ROM update.zip and remove any files/commands that flashes boot/devtree/recovery/anything.
2. Install this new file on your phone via CW Recovery.
3. Boot into bootmenu and enable ADB so you can read logcat while phone boots.
4. Choose Boot/Normal. If your ROM uses 2nd-init you will need to place/edit/adapt bootscripts into bootmenu 2nd-init folder.
5. Check logcat for errors:
- If you're getting HAL errors you're going to need a new kernel;
- If you can start android without getting HAL errors but still getting errors and bootloop on android animation you should try to replace libs with appropriate original ones.
6. Once you are able to boot android you should test it's features to see what needs to be fixed.
This is what I have to say for now. The thread is now open for discussion.

At this week, motorola has just pushed the GB official update for Droid 2 and Droid 2 Global....
Can i try to port this new rom to milestone 2 and after a success boot, fix the radio..??
I was asking that, because some people has success on port CM7 to milestone 1, when it originally maked for droid 1...

It may be possible, but you'll have a hard time fixing the baseband.
You may have to mod the init.rc scripts and find the right radio binaries (rild is one of them) and drivers.
Ask those ms1 people for help, if they are still with the same phone...

I don't know if this will be relevant or not.
I wanted to know if to do any of this, having a Linux distro as OS a must or can I try my hands at it on a windows based machine. I mean I'm sure that a Linux distro will give certain advantages (as Android is based on UNIX/Linux) but can we get things to work a 100% on windows.
If yes, then will someone be kind enough to get give the list of all softwares etc. which will be required to do the job on Windows machine as well as a Linux machine.
I do know a few softwares but I'm not sure if I have an exhaustive list. I would like to learn and try and at least be able to modify in bits n pieces to begin with.
I apologize if this wasn't supposed to be asked in this thread.

The only thing i can get from SBF is a bunch of smg files.
But the only ones i can open are
preinstall.smg
CG39.smg
Is there a way to open/see the rest?
2)
Im trying to modify the CM7 rom, what boot does it use? 2nd-init or 2nd-boot?

i guess it is second-init. but not sure

thanks a lot for this !!!

SMG files are disk images of certain partitions of your flash memory.
You can only open CG39.smg and preinstall (CG66.smg) because they are the only images in ext3 format. The rest of images may be on ramdisk format or some proprietary format. For more details on partition codes take a look here:
http://and-developers.com/partitions:cdt
You may be able to open and see contents of other partitions but the only one that matters aside from system and preinstall is the boot partition (CG35.smg), which contains the init scripts we should mod in order to make they work with 2nd-init. Boot partition is in ramdrive format. More details here:

Edit: To see what boot your CM7 uses just go inside /system/bootmenu/config and look for a file called default_bootmode.conf. That should be the boot method used. It's normally 2nd-init.

Don't worry, this is the right place
As for your question: yes you can work in windows if you like, but using at least a Linux VM is more productive. I don't have a full list of applications to give you, as different mods may require different tools, but I advice you to have at least:
- Notepad++ (essential for editing text files and keeping linux end-line format);
- dsixda's Android Kitchen (http://forum.xda-developers.com/showthread.php?t=633246)
- 7zip (or some other compress tool you like)
- Moded putty for ADB as working with windows command prompt really suck (http://forum.xda-developers.com/showthread.php?t=803225)
- Oracle Virtual Box (if you are going to use linux VM).

Oracle Virtual Box is an application that lets you run an operational system on a virtual machine, in other words, it doesn't install linux on your real computer. It's a very useful tool that I use everyday. Google for it and learn a bit, you won't be disappointed. About kitchen: the link I provided was download + guide. Read it again. If necessary read the full thread.

I know a bit about virtual box but as I said I'm not allowed to have softwares not approved by the IT team to be present on the system. Though I can get away with small things like notepad++ and 7-zip, having virtual box on my system may raise some eye brows.
I'm trying to arrange an alternative system.

Me neither. I must do almost everything at home, and at this very moment I simply don't have any free time. I'm afraid you're not going to see me here very often anymore (maybe in a few months? a year? well, it might be a bit too late for milestone2...)

hi. Have a question, I want to remove baseband from a flashable zip (lets say, CM7 from Tezet) , is it posible? I dont know where to look for it (baseband). Thanks!!

Baseband is located in \system\etc\motorola\bp_nvm_default\
But don't remove it, just replace it with files from ROM, which have baseband you want.

Check my Defy PA thread in 12-14 hours cause I'm about to go to work and I'm not gonna feel like making a MS2 PA thread or updating my Bravo PA thread -- but the Defy Thread is always up to date when I put out new roms.
Also, I'm looking to get either a Defy or MS2 -- I've heard that there's 3G issues with AT&T users (which I am) with the MS2 -- Apparently the MS2 has different 3G frequencies than AT&T. Are there any AT&T MS2 users who are knowledgeable about that? While I can deal with no 3G, edge only, calls only -- I need to make sure I can at least do that before I commit to something.
I'd rather have the MS2 because I want a hw keyboard and I don't have the $300+ to try and get a Photon Q LTE from eBay (and I don't have to change up my repos if I get a MS2). If anyone here knows of a phone that's AT&T compatible, Defy code compatible, and has a keyboard, please let me know.
Thanks.
//Normally I'd post the latter half in the Q&A section, but ya'll don't have one so I'm just gonna piggyback
//My Bravo doesn't have a Q&A page either -- it needs one that's not my PM box...Don't PM me on how to root your phone and flash CM7 -- read one of the 5 guides on the first page of both General & Dev...:silly:

Ok devs need some help here.
I am trying to port a rom to our Milestone 2...but it bootloops on rom animation.
I tried to logcat it but I don't think it gets as far as adb server to detect the device.and just keeps saying "waiting for device"...so I end up with no logcat to diagnose the problem.
I can logcat my current working rom but only after the phone boots....am i missing something here? please, help
Any help is very much appretiated.
Thanks a lot in advance

[Q] Can't seem to build a custom kernel

I am trying to compile a custom kernel,
I succeed to build one but I can't boot him, when I load the kernel I go in to boot loop
I haven't made any real changes to this kernel I really just downloaded the source and compile it
The version match its a GB kernel 2.6.35.7 I disabled the lag fix, still it goes to boot loop.
any ideas?

What source code did you try to use to build this kernel? Links would be awesome.

Well I tried this two
Code:
github.com/Krylon360/SGS4G_Kernel_GB
opensource.samsung.com/index.jsp (SGH-T959V-TMB_GB_Opensource.zip)
I did
make clean && make mrproper
make vibrantplus_rev00_defconfig
make -j8
and then I loaded the kernel via heimdall

Building the stock kernel
I have run in to a similar problem. One issue I had to get past is the stock rom source does not have have the initramfs included. It is needed so the kernel can boot into a file system before it can start loading loadable modules and mount the rom filesystem.
I have been able to get an initramfs by extracting it from the original rom, The issue I have is it is loading all modules, but the rom devices will not mount as the /dev directory is empty and the mount needs them to mount the file systems.
This may be off topic for this forum. If you want to PM me, I'm willing to let you know what I have found out.
Tom

You should keep discussing it here since it does pertain to the phone and it'll be useful for future reference

Agree with FB.
I have ran into the same problem. I was unable to find a way to get it beyond boot loop so I scratched the project. I am definitely curious on how to get this working.

DISCLAIMER
I am NOT a kernel developer, just a programmer that has done linux programming before, and is trying to understand and build the kernel.
I will share what I have found out through my attempts to build the stock rom as delivered from Samsung.
I have searched XDA and Googled the web in search of the answers I need with some success as well as dead ends. I am not looking to have the answers handed to me on a silver plate, but a few hints or links to point me in the right direction is helpful.
To start:
Recommended Hardware needed:
Search the XDA for AdamOutler threads on building the serial interface via the USB. Highly recommended reading as it helps to see what the kernel is doing when it is in the bootloop. All the important parts was purchased from his recommended supplier(s). Thanks AdamOutler for the information!
What I know about the samsung kernel source as delivered:
1) if you follow the readme in the kernel, it will build cleanly. However, it will NOT run, it will bootloop!!
2) If you intend to only build the stock kernel, I recommend making sure you are starting with a stock build installed on the phone. I suggest the same release version you are trying to build.
3) After you build the kernel and load it ( the zImage file is loaded via Heimdall ) the first problem I ran into was the initramfs. It is not included in the source and must be created from scratch or obtained from another kernel.
4) Once the initramfs is being built and included in the kernel, the next problem is the driver modules that are included, have to have the same version as the kernel. You will need to figure out the version by the kernel debug messages on the serial/usb interface mentioned above. Once the versions match, the kernel will load them.
This is where I am stopped... once the drivers are loaded, the init scripts mount the file systems. This does not happen with my kernel. I am still investigating this. I think it has to do with the /dev files for the mount points not being created/missing. I have not found the piece of info yet points me to the solution. Most of the links I have found pertain to linux on an x86/64 platform. I have found little on embedded linux and how it works.
That is all I have in a nutshell. Feel free to comment and ask questions. Remember to search! Use different forms of your search terms, use different working. I like to use the 'yippy.com' search engine as it places the results in categories.
Good luck!
Tom

Krylon's tree is stock, no changes.
It has all the problems I fixed in my tree.
I have a lot of uncommitted changes, but you can find my work at: https://github.com/bhundven/
Regardless of me being on xda or not, I am still working on sgs4g.

Aww hell bhundven! Refreshing to see you stop by!

Thank you everyone
mccabet, You actually saved me some time because those were my next two step
I was looking for the initramfs and I didn't find it...
Could you please share your?

I do not have my initramfs file available to me at work. So here is the info I used to get my copy. You will need an original rom release ( I used the heimdall one-click from bhundven ) to extract the zImage file from.
Here is the link to info on how extract your own initramfs from a kernel image (zImage):
http://forum.xda-developers.com/wiki/index.php?title=Extract_initramfs_from_zImage
I used the improved script mentioned at the bottom of the page from:
https://github.com/mistadman/Extract-Kernel-Initramfs
After getting your initramfs, you will need to modify your vibrantplus_rev00_defconfig file and change the following parameter to point to your initramfs you extracted:
CONFIG_INITRAMFS_SOURCE="/path/to/initramfs"
Hope that helps.
Tom

Ok it seems like I was able to boot the kernel, no more boot loops thank to the initramfs but
The system isn't loading, it get stuck on the "Galaxy S 4G" page.
and when I load recovery it gives me lots of error so as
E:Can't mount /cache/recovery/log
E:failed to mount /cache (No such file or directory)
it goes on and on but its all the same...

I may be off-base, but do you know if /cache and the other file systems were the Samsung rfs filesystem or the ext4 filesystem? Standard recovery can't mount ext4 & if your kernel doesn't support it, then it won't be able to mount them, either.

I thought so too so I removed the lag-fix and return to rfs
but this is neither because apparently there are no stl devices :\
I pulled out the recovery log
Code:
http://pastebin.com/hDCNbdne
Code:
failed to mount '/dev/block/stl11' '/cache'(rfs) -> No such device
Now I feel like an idiot because I can't seem to find what is it in the kernel config
moreover I tired to pull a config from a working kernel and I basically got the same errors
Any ideas?

Well the solution is simple, apparently version magic didn't load the kernel modules
for rfs_fat and fsr_stl...(you get the point)
now I can't to find way to compile them it seems as if someone removed them from the kernel tree and I can't load them either
I tired several modules from different kernel well all result in failure.
so any ideas?

I wish had some, man. I've never compiled a kernel for Android. At least, not yet. However the moduel code should be somewhere in the kernel tree. I believe Android is a layer on top of the Linux kernel so the source may be there.
I'm still reading about and learning the platform side of Android. Hopefully one of the devs around can provide some solid guidance.

Ok no offence but this kernel is worthless
even if I load the modules into the kernel I get a errors because of the unknown symbols
bahh any ideas anyone?

That is as far as I have gotten. The drivers for the RFS ( drivers/tfsr ) are not loading and therefore the /dev mount points do not exist. The default build config flags ( CONFIG_RFS_FSR=m and CONFIG_RFS_FSR_STL=m ) are to build the module as a loadable module. I have tried to build the module with no success. Still investigating when I have the time. I was even thinking of looking at the Epic 4G MTD build and trying that. The problem there is if I can not solve this problem, I probably solve it by trying the MTD conversion. ( Except to brick it.)

if one of you kernel devs gets a bootable MTD kernel hit me up... I got a rom that needs some mtd loving

I do not claim to be a kernel developer. I am trying to understand and build the base kernel. If you can help me get past this, that would be great! I need to take baby steps before I can start walking. Once I get the build to work and boot completely, I'm game to go further, but have to get to a working base before we can continue. I understand the more experienced developers don't want to be bothered. I understand they have other jobs, and families. So do I. They became as great as they are, through hard work, experience and asking the right people the right questions. Asking the right question also applies to Google. The query only returns the matches to your query. Change a few words, get different results.
I'm not looking for someone to hold my hand, I want to learn by doing, not having it done for me. Just point be to the bread crumb trail, and I will follow.
Right now, I am at a stand still until I figure out why it is not loading the tfsr module. If that is even the problem.
If I make any progress, I'll post it here for all. If I am wrong, please correct me so we all don't go down the wrong path.
Thank you for listening.

The Theory of Everything (Building MTK from saucery) asop cm miui ubuntu

Welcome​
I have started this thread for the THEORETICAL development of the mt6732/mt6752 from source if such a thing happened to exist which of course it does not.
While compiling from source is pretty well documented :good: compiling MTK is not so well documented especially the mt6732/6752.
I have tried to keep this thread as ambiguous as possible and hopefully we will be left in peace to iron out any difficulties.
DO's:
I am a Total Noob myself to compiling from source but experienced enough to use the xda search box, Google and Youtube first before asking any questions. If your still confused after using the above then by all means ask here.
DON'T s:
If your a noob who should happen upon this thread then by all means read and learn but please respect the dev's by not asking random question without searching first :fingers-crossed:
SHARING:
Please only share things of a sensitive nature with recognised members who you know and via the PM. :good:
Lets just see how far we can push this Kernel

I am here, reporting for duty. If anyone wants an extra "potato" because he has too much "ketchup" for use feel free to ask me

Just to be clear
I am new to compiling from source in any shape or form
I believe the kernel to be not a problem and I know dev's are working on getting our phone on cm and maybe others :fingers-crossed:
But me being me I am very curious and would like to understand how we would go about doing what @varun.chitre15 managed to do for the mt6582 Here
I have the PC all setup for building now thanks to @carliv great guide Here and the cm and android tut's I also found this useful guide on youtube by Dave Bennet Here
Our device is not on the cm or google repo so how do we add it locally.
Do we need any special commands for mediatek
Could we use the mt6582 repo and substitute or mod the files
As you can see I have more questions than answers as normal :laugh:
I dont want to tread on any toes here or take over current developing but just want to learn as said in the OP there is a lack of mtk guides regarding this.
If I missed a clear mtk guide then please post the link to it. :good:

In short your looking at manifests. http://wiki.cyanogenmod.org/w/Doc:_Using_manifests

I have compiled and flashed a kernel, I've been running it for 24+ hours with no obvious issues. It's honestly very easy to just get it to build if you don't try to make major changes.
I have (very lazily) tried to change a couple of things in the config to fix the known issues (OTG, compass): unfortunately I have no way to test the OTG function right now, while the compass did not magically start working. On the other hand, the notification light issue which is introduced by V8.4 is not strictly or exclusively kernel-dependent, since I am running V8.3 with my own kernel and the notification function is intact. That's all I can share at the moment.

Can you switch on and post the /proc/config ?
Regarding the notification lights, I think v8.4 introduced the custom partition (might be wrong on that). Running grep -r "ro.notification.breath" /system/ the only result I got was services.odex (might have been settings.odex). I've bak(smali)ed it but couldn't see the difference between the two that would explain the change.

The config file is attached to the post, it's too big to paste it.
I have tried the new ROM which came out today, then flashed my kernel. I can't use either SIM card anymore. Flashed the boot.img that comes with the ROM - same. I guess I gotta go back to V8.3 for now.
The new ROM doesn't seem to be the same as the OTA: it reports as: Elephone_P6000_02_V8.0_20150206.
About the notification issues (which bothers me the most), I haven't had much time do to more experiments, but I was thinking this (which probably also led to my confusion*): there's a chance the functionality is not removed or shut down, at least in the intentions of the maker. After all, in V8.4 (and in the new ROM), when the phone is connected the light stays on, while notifications make it breath. While not a desirable behaviour (at least IMO), I wouldn't call it... a non-behaviour, so to say. So perhaps the functionality itself is intact but something is altering the way it works, for whatever reason. I also did some unpacking and grepping a few days ago, but I couldn't find anything useful.
* At some point I thought the issue was fixed because the light was breathing while connected to my PC, but it was probably because I had a notification to read.

Lets not speculate too much - but perhaps there was a minor board change between the first and second preorders, notification could be a problem with granting notification access (in settings) - could this be a selinux issue? It would explain why things like Light manager work - as you grant them notification access.
For lost Imei - can you compare the custom partition to the one in the ota?

I think you can use the scripts in the root of the source code to build the kernel? make<something>.sh.
Make sure you're on Linux (Ubuntu preferred) and that you have all dependencies installed correctly. To execute the script, simply go to the Terminal, cd to the location, then type . make<something>.sh

Have a look at the README.
Does make menuconfig work here?

These few simple instructions from the readme file enable you to build a working kernel (at least in a Linux environment):
Code:
How to Build
kernel
======
1. Get the prebuilt cross compiler from AOSP website:
$ git clone https://android.googlesource.com/platform/prebuilts/gcc/linux-x86/arm/arm-eabi-4.6
2. Add required cross compiler to PATH:
$ export PATH=/YOUR_TOOLCHAIN_PATH/arm-eabi-4.6/bin:$PATH
$ export CROSS_COMPILE=arm-eabi-
3. Then use the following commands to build the kernel:
$ ./makeMtk k01q_e new k
make menuconfig can be made to work, but you need to set some parameters and I can't look into it right now.
You previously asked something about the custom partition, I need some guidance there as I am not familiar with the IMEI issue.

Yea wasn't sure about menuconfig as mtk uses projectconfig rather than def_configs.
In the custom partition there are files like /custom/etc/firmware/modem.img etc. When messing with a Flyme port it was these files (and possible conflicts in /system) that caused an IMEI:nul.
FYI I opened the custom partitions on windows using an ext viewer after running the imgs through sgs2toext4.

Not sure if you guys have seen or read this but it's a pretty comprehensive guide to building the mediatek kernel by @MasterAwesome and should really be compulsary for all kernel related things thread here http://forum.xda-developers.com/showthread.php?t=2754513
@HypoTurtle
Regarding the custom partition this is or could be a problem for us now and in the future and may require further investigation. The cm sprout branch has the modem.img in the (normal place /system/etc/firmware) but as you say ours is in the custom partition which is probably to protect it from bad /system flashes
Thing is I see no normal type link to it in the /system/etc/firmware so it must be linked some other way which may explain why all my port attempts failed as none of them used a custom partition (Asus_X002)
Maybe we will have to repartition the emmc to a standard config and alter the kernel (if the links are set via the kernel that is) for cm and other ports to work smoothly as I am unsure just how everything is linked up.
I have not had much experience with custom partitions so someone one know's of a good info source please link it. :good:
Hopefully Master @Santhosh M can figure out what's going on with the custom partition :fingers-crossed:

The partition is symlinked from .../by-name/custom (which is symlinked by the kernel from dev/block/mmcblk0p12) to /dev/customimg which is mouned after an e2fsck to /custom. /custom isn't linked to /system, it's just added to the global environment (init.environ.rc), will need to check on the environ, I'm on flyme and it has /custom/lib added to the library path (which doesn't exist).

Haha thanks that explains a lot of weird things perfectly. :good:

What's the problem or what is the issue here.
Mediatek compiling guide ( by masterawesome ) that you have linked to is not actually practically this mtk kernel is done and is just way too complicatedly explained.
There is no defconfig stuff or pulling config.gz from phone in mtk. In this new source its just simple. Set up your toolchain path. Execute the makeMtk followed by the project no u want. Get zImage and patch it for mtk header and merge it with stock ramdisk. For this newer mtk chipsets repack has an extra stuff where u have to be careful of kernel command line parameters.
That's it the kernel stuff in mtk
