[Q] Dynamic BoardConfig.mk System Image size? - Android Q&A, Help & Troubleshooting

Hi all,
In BoardConfig.mk, there's an option to specify a systemimage size. What is the purpose of this? Is there some way to just make it dynamic based on the required size (and plus maybe a little extra)?
Thanks!

u cant increase the size of system or data of a device
but you can use your external sd card inplace of /data by mounting and using some scripts so what you want to do with it please be specific

You cant increase the system partition it is a hardware thingiee and for porting contact any dev you can port roms to your mobile you dont need a 750mb system you can do it with 375 but not touchwiz i guess may be any cm

MOJO Kernel source

Hi,
Just wondering if/when MadCatz will release the kernel?
I know linux being GPL, it has to be shared, but not sure about Nvidia's sources?
I'm new to android but not java(my day job) and linux.
I've compiled and installed my own kernels on desktop and on my mobile phone (Nokia N900).
I want to try and add a few things.. ie filesystem/DVB/webcam support etc.
Following this how to.
Apologies for the delay in getting this released. Here's the kernel source:

Sweet! many thanks :victory:

:good:
omg.... does this mean we can finally have a cifs module!? AWESOME!
So now that the kernel source is avialable, I'm looking forward to the first custom kernels. Would be great to have some kernel optimizations and other tweaks built in :good:

Yes i hope someone can make a kernel to re-apply resolution settings on the m.o.j.o, as mad catz said to me via a phone call some tv's can't adjust to 1080p natively because the os is preventing it,and stupidly they removed the resolution changing slider in settings don't ask me why they did that?
If there is a way to set resolution without endangering the console booting up afterwards would be awesome,i am thinking it is there but hidden away and accessable some way but don't know how,developer options can be opened but not resolution settings as far as i have found any way.

I think it automatically sets the resolution based on the TV/monitor, try a different one?
TMK, the slider has nothing to do with the kernel.

I would do that but i only have a panasonic 50" plasma it's a 600hz 1080p it p50x50b model,there are 2 variants of it a hd ready and a 1080p model,i know it's the 1080p model as i used blu ray and xbox 360 and a wiiu etc in 1080p modes so it's definately not 720p only on my model.
I still think it is possible to reinstate that hdmi resolution slider though? I would love for someone to find a fix for that to bring back the slider though.
It also has nothing to do with the overscan as that's off,and the guy said it's an argument between the console's os and the tv,but maybe if i had an option to change resolution within the console when in operation it would ammend this,resolution changer pro works then looses usability eventually and it's awkward and time consuming to get that to work,only for it to stop after a time?
There is no forced hdmi resolution setting in the tv menu unless of course there is in engineer mode but all that seems to do when entered is show test and it's results coming up as ok,after testing it factory resets the tv as well so sick of trying that now.
Someone needs to get a custom rom made up with kitkat and 1080p natively set.

Hey,
I suggest downloading with wget or a good download/ftp application if it's timeout on you.
It's not corrupted, it worked for me and the date stamp is still the same.

It doesn't time out but it says some .c and .h cannot open: Not a directory when I use tar to extract it. Then I thought that I should install something else to extract and tried ARC. It extracted and then the same message box as appeared in windows 7 OS "file already exists cancel or overwrite"
I then said overwrite and then I get the extracted package. I just want to ask you that when you extracted it did you got any errors? What procedure you used to extract it? I downloaded twice with same results...

OK as per your suggestion I used wget c and the address. That gave me again the same file and upon extracting it I am getting same errors.
May be that the file isn't corrupted as you can extract it and its possible that I am doing something wrong in extraction..
I tried to create the kernel from sources and got a make error, to remove that I must delete a line in the make file (Line no 603) and after that I can successfully compile the zimage. But the issue is that after completing the procedure for boot.img file the original and compiled one has a difference of 0.1 MB and device don't boot with the newly compiled boot.img
Please if you can provide me with the steps on how you exctracted it and which OS you are using?then it will be really helpful. Also can you please upload the makefile of kernel and config.gz file you are using to make the kernel...
One useful information that can prove that there is an issue in extraction:
Extracted content on windows OS with Administrator priviledges: 42889 items , 487.8 MB
Extracted content on Ubuntu with Tar and other utilities: 42692 items, 482.5 MB

Seems like you are the only person who can help me as no one else seems to be active on MOJO development department. Sorry to disturb you again friend but you know I tried extracting on Android too and it failed there too!
I am completely exhaused with two days 24hrs of searching only extraction process. Please let me know if you successfully compiled and booted the kernel on your MOJO. If yes then I need more information from you as I had compiled the kernel but as I told you earlier it didn't worked... Please reply ASAP

Hi,
I'm in Aust. so there's a time difference.
I'm also about to leave on a 4week holiday and don't have my mojo dev stuff on my laptop.
I just used tar -vxzf filename
I think the only errors were a bad lsymbolic links which arent required.. from memory I could be wrong.
If you read the other threads here, I and someone else explain how we got the kernel compiled and yes it works fine.
http://forum.xda-developers.com/showthread.php?t=2691985&page=2
You dont use their makefile you recreate it .
If this is your first linux kernel or even android kernel, it's a tricky process and it takes time research all the steps.
Good luck

I have gone through with the links you provided already and I understand every bit of conversation. Yes I am new to kernel compiling but its reasonably understandable.
I respect your valuable answer no matter when you reply since you have a minute for me and don't worry about TimeZone differences as I am not in a great hurry, I just don't wish to waste time on errors for which I ain't responsible
OK I tried compiling modules for which I had to compile the kernel to get the module.symvar file and "THE MODULES WORK!" that too with the Default kernel Makefile and ofcourse my own module Makefile.
"You dont use their makefile you recreate it" this line you wrote.. What do you mean by that??
I mean were you talking about the kernel Makefile or our own module Makefile, Please clear me here? As far as I know the Kernel Makefile should be the same when only compiling the stock kernel as that is my purpose "JUST TO COMPILE THE STOCK KERNEL"...
My compiled kernel boots but just shows a black screen! I don't want to spoil your holidays sincerely but if some help I can get from you then I will be able to relieve me from this burden
Hmm got it compiled finally even after that make issue with -k flag to make
Also all I needed was ramdisk from latest OTA and not the one from the kernel. That was the issue with kernel booting but it freezing at blank screen...
RESOLVED :highfive:

Glad you got it working.
Re the makefile, I think you have to run config first to check your systems compilers/linkers/etc which then creates the makefile.

is there any reason this is done via some random ftp server and not some place like github/bitbucket with better management? or heck even sourceforge would be an improvement.
is that account for developer outreach? are there any datasheets on the components used in the device? sony does a beta program for updates on their flagship devices have you considered doing something similar where people can grab images and help test updates? ever think about tossing the device trees up for aosp to help encourage a porting of 3rd party roms and spread the community?
the nook color and touchpad being hack and having Cyanogenmod and the like being ported to it drove sales up, i would imagine having a hackable android console that isnt some no name chinese brand would probably do decent. unfortunately now with android tv you guys have some serious competition on the horizon, its a matter of how you go from here and try to make the most of it so everyone already has your product and doesnt need another.
edit: i also see there is several updates yet only one kernel source... any chance of updated source?
@Mad Catz Rich
The new update (205-TS) has a new kernel build of May 2nd.
Any chance that can be put on the server?

dont take this the wrong way but you can test it out and let the community know. I mean its just addition to your build.prop as I read it and it wont blow your phone up
Also he has 3 thanks and I would assume thats there for a reason

1. I'm sure this is harmless, yet, asking for backup isn't unheard of here. I'd rather ask before trying to see if this has been vetted by others. Not clubbing baby seals by asking.
2. People click "thank you" all the time. Look I even clicked it for you.
Don't worries, the zip create a backup of your build.prop before change and add new line on it. But you are right, 200 download and nothing people say it's good or not ! But i think, no news.... Good news !
Good Morning. I could not even test the impact , but the OPO remains functional in any case. The changes in the build.prop set the OPO not in the bootloop .
Does this patch fix the 2G issue that the voice is scrambled in calls when using the internal mic?

I get it but I mean research the zip and see what it's doing then try it. We flash roms to our phones from people we do not know everyday. Oh well I hope you tried it and it helped you out. No seals were harmed in this post.
Take it easy
This fix (the first version) did NOT work for me. I'm running on the latest nightlies of CM12 on my OPO. Is it worth trying v0.1? Also, for those worried about anything going wrong you can easily just flash the latest nightly directly or via CyanDelta and all the changes will go away.
+yamsta have you see in the build.prop if new lines are here ?
Wouldn't it be easier just to provide the required changes as well? I do not like flashing ZIPs without exactly knowing what is going to be changed.

for more reliability, it's easier for the user to flash a zip than manually edit a file and less dangerous.
For more simplicity, add the zip to Cyandelta additional zip automated the process after all new nightly

Maybe so, but for more clarity, it's always better for someone who puts up a fix to state exactly what the fix is doing, so users can evaluate whether they want to try it or not. Please list out the changes that your patch makes, and how it tries to fix the issue. Thanks.

[Kernel][5.1.1][P605] Stock SELinux Permissive kernel (OI5)

Based on the first 5.1.1 sources, version OI5
Modifications:
SELinux unlocked
Disabled protection does not allow to boot the OS(disabled at the level of Linux kernel)
Permissive mode is set automatically at boot (without the possibility to switch back to enforce)
Before(you can do it after flash,but recommended before) installing the kernel required go to build.prop,find ro.securestorage.support and set the value to false. System may forget your WiFi passwords after flash custom kernel.
SecurityLogAgent has to be removed or frozen.

Bluecat, thanks for this! I wonder if you know what differences exist between the P605 and the P607T. Also, did you use the EUR_LL source from Samsung's opensource portal? Its strange that they already have the source out for the P605, but nothing yet for the P607T which received the update first. Makes me think maybe the code base is the same and its only the bloatware bundled by the carrier that differs?
I am also curious to just learn and get my hands dirty with this. Can you share the Makefile for this kernel, or just point towards the guide you used (assuming you used one) to compile this?

Sorry,but i dont know differences between the P605 and P607T.
Yes,sources SM-P605_EUR_LL_Opensource.zip and version OI5.
If you want check have code 607 and 605 differences or not you should check checksum both original zImage(linux kernel). Extract them from both boot.img and compare.
Version 2 use standart selinux permissive way used by mostly kernel developers,it's have many changes in code now and it's will be very long to explain how to change to permissive,just use my sources available now in first post and compare them with original sources.
If you talk about how to compile kernel...was use many guides and other forums...hard part was only create .config file

Will try to extract the zImage from the P607T boot.img. I do not have the P605 though, do you know if the stock boot.img is downloadable anywhere?
Thanks for uploading the source. I just finished downloading the original source from the opensource site, will compare the two and try to understand.
I do know how to complile a linux kernel, I meant can you share the .config file (not the makefile, as I wrongly stated earlier), so I can see what has changed across the entire kernel. Rather than just change one line directly in the config file to disable SELinux, I wanted to use make menuconfig and go through the whole process, just to learn more about android kernels. But since I do not know much about the hardware and driver requirements, wanted to see a stock .config as well as your changed .config to understand.

Why does the wifi password get forgotten on every boot?
Any fix for that matter?

Based on the first 5.1.1 sources, version OI5
Before installing the kernel required go to build.prop,find ro.securestorage.support and set the value to false. System may forget your WiFi passwords after flash custom kernel.
SecurityLogAgent has to be removed or frozen.
Flash kernel in odin.

Maybe you missed the update to the original post, the fix is as above, set securestorage to false. Since you have already flashed, you can still go to build.prop, make this change, reboot, and you should be fine.

I tried this. With ro.securestorage.support false. Still no WiFi passwords saved after reboot.
Other than that, this works great!
Xposed (for Samsung by wanam) works great!
valexi, the only thing Ive seen suggested in your case is to reflash the firmware. I do not know of any other solutions for this, because pretty much everybody with this problem seems to have solved it when they changed the securestorage thing.
BlueCat, I went ahead and compared checksums for the stock p607t and p605 kernels, they do NOT match. I also extracted the kernels themselves and the zimage files are of different sizes. I then compared the default config files of the P605_LL_EUR source with the only available source for the P607T, which is KK ... They are considerably different. I am of course going with the assumption that the core config for the kernel between KK and LL should not be TOO different, but of course, this is NOT a reliable test. Lastly, I should also say, the P607T source contained an insane number of config files in the Arch/Arm/configs folder, while the P605 source only had three files! I only compared the three that were common ... It seemed like the 607T has the config files for every possible version of the device, while the 605 one had very specific configs for that device only ... This I am speculating based on the fact that the 607T folder even had a msm8894_sec_l03ltmo_defconfig file in addition to the msm8894_sec_l03leur_defconfig file in the 605.
Will do more comparisons over the next few days, but it does seem like there are more changes under the hood between the 605 and the 607T than one would expect. I really wish samsung would release the source for the 607t, but if you check that page, there is just one single KK code there and nothing else, so it does not seem likely anytime soon

Ok,I found a solution.
You need to remove SecurityLogAgent

Re,
Ok remove SecurityLogAgent and folder Container it is ok...
But delete all other knox and Klm gives a problem with the playstor. (Certain protections cannot be erased)
Hey guys,
Great news around, especially with roms like Alan-B's. Thanks for sharing :good:.
Running 4.4, planning to update 5.x as soon as I'm sure I can run Linux Deploy (meaning the need of permissive kernel), though I can't find any intel about VTS (Virtual Terminal Support) enabled kernel. I've been looking for months a way to run framebuffered distros and looks like this is the solution.
I could try to make it myself but I have no experience in kernels, would someone mind give me a hand to get to this goal? At least give me a hint to "quickly" develop and try one, to see if it works and how well...
Don't even know if I'm looking the right way anymore, so thanks by advance for any help and again for the sharing :highfive:.

But when I reflash the firmware how can I set securestorage BEFORE installing permissive kernel as I don't have root to change build.prop?

You can't. Reflash, root, edit build.prop, reboot, set wifi password once again, reboot, it SHOULD be fine. If its not after this sequence, Im not sure what else may work. Every case of this particular problem that I've seen was resolved with this solution.
Luckily I didn't reflash yet. I checked again build.prop and securestorage was true. For some reason it didn't stick first time.
I edited it again and now WiFi works as intended. So I can say that this solution works. Great kernel.

Xiaomi kernel reverse-engineering?

Hello guys. Found this guide for kernel reverse-engineering via IDA pro. I have done several steps, but can`t separate the image itself from the extractor in the zImage file. Should i even continue, or the idea is useless? Is it`s useful, you can download and try to unpack the zimage by yourself, and i also have the symbols for a script.

I saw your post about this in another thread, and I did not want to discourage you, so I kept quiet. But, since you now ask directly, I will advise you to not waste your time. Even with full source code, kernel hacking is not for the faint-hearted, and is far from a trivial exercise. With no source code (or with incomplete source code), you might as well want to try getting hedgehogs to fly to Mars ...
Hi there! First, I'm no dev (got some experience about building Roms/Kernel from source) so sorry if I ask noobish things .
I got the same problem with the mi4s zimage (want to reverse engineer because official kernel sources are incomplete..) couldn't I just extract everything out of boot partition and create the source-code out of that? or what's the Problem by doing this? If the extracted source code (for whatever reason) is incomplete, wouldn't it be possible to get the missing things from official source released by xiaomi?
Thanks in advance

You want to extract compilable linux kernel source code from a compiled kernel? Sorry to disappoint you - but human beings will learn to climb a rope from Europe to the moon before you could achieve it. You might be able to disassemble the kernel, but you would not get anything near something compilable.
Hint: if it could readily be done, do you not think someone in these and other forums would have done it already?

There are lots of people who already did this! (see xiaomi forums redmi 3s, mi pad, Samsung galaxy s3, i9000/9001 etc. etc.). And those kernel are indeed working (even better than the ones from source) (yes, I tried it).
U ask why no one already did this? maybe because Mi4s community is very small (not even our own section..) and its quite a new device.
So why is it possible with other phones but not with mi4s?
Ty for help and explanation
Btw, can u explain it technically? not like "humans will learn to breathe in space before"....

If you mean that somebody patched a binary kernel, yes, that can be done, and I have done it myself. If you mean that somebody disassembled a binary kernel into compilable source code, I very much doubt that. If you claim that others have done it, why not post a link to the source code that they extracted, so that we too can try our hands at compiling it?

I am totally unconvinced about the claim that "it is possible with other phones". Please show the evidence.

A simple example - http://blog.packagecloud.io/eng/201...-and-disassmble-a-linux-kernel-image-vmlinuz/
Scroll to the bottom of the page and see what you will get for your efforts. Try compiling that. Better still, try editing it to add missing things or fix/remove broken things, and then compiling it. Finally, you are talking about 15 million lines of source code. Good luck.
for example here: http://en.miui.com/thread-125557-1-1.html
http://forum.xda-developers.com/android/software-hacking/how-to-reverse-engineer-kernel-t3137384
Maybe we're talking about different matters, I just want to implement UV and OC in the original xiaomi kernel to use it with smiui... As you seem to know a lot about linux kernels, how can this be done?

These are the bases of your claim that it can be done? I cannot see anywhere in those two threads where anybody was able to do anything useful with what was being proposed.

I know how to compile linux kernels when the full source code exists. I also know how to patch such sources to edit/add/remove specific things. I also know how to patch an uncompressed binary kernel if I know exactly which offset(s) to patch and which values to substitute for what is already there. I have done this for 32-bit RK3188 android kernels in my old tablets (search the ARCTABLET forums and you might see some of my historic work on overclocking RK3188 binary kernels). This was easier for RK kernels than for MTK, and much can go wrong. If all is that is needed for what you want to do is to change specific values at specific offsets, then all you need is a hex editor and the necessary information about offsets/values. If you are trying to add a new feature, then you need the full source code from the vendor.
Get yourself a backup phone before trying anything of the sort. Like I said before, I wish you good luck!
Thank you for that information. Wouldn't it be possible to edit the things in zimage (unpacked) and then just re-pack it and use it? There shouldn't be anything missing if I'm able to find the correct offset for the lzo compressor...

It is a binary file, which of course you can edit with a hex editor. But what exactly are you proposing to edit in it?
Isn't it an image containing files from Kernel? Otherwise they wouldn't talk about extracting it... Yes, I need to edit it with a hex-editor to remove the lzo header (zimage is a self extracting archive, but i want to extract it with normal zip extractor) but cant find where the header starts.

Your questions show a misunderstanding of what a kernel is. The best I can do is to refer you to Android kernel development information - see e.g.,
http://www.99droid.com/android-kernel-development-tutorial-let-the-development-begin/
http://source.android.com/source/index.html
http://source.android.com/source/building-kernels.html
At this point, I bow out of this discussion.
