[Galaxy Tab 4 Q&A, Help & Troubleshooting] amyren:
Being a newbie on compiling I did try to compile a kernel using this Guide: http://xdaforums.com/showthread.php?t=2486098

Here is the console output I get:

*************

The log file itself looks like this:

*

SOC specific random number generation (ARCH_RANDOM) [N/y/?] (NEW) aborted!

Console input/output is redirected. Run 'make oldconfig' to update configuration.

********

Now, if I try to to run 'make oldconfig' it will output some error similar to that above, and then I get about a million questions I must answer to go on, like

'SOC specific random number generation (ARCH_RANDOM) [N/y/?] '

This was done according to the Guide, apart from I did not have my source from github, but I downloaded from opensource.samsung.com and extracted the kernel.

The config file I copied into .config was named msm8226-sec_matissewifi_defconfig, was this correct or should I have used msm8226-sec_matissewifi_defconfig?

I might try again tomorrow, cause I'm downloading a kernel from github right now, but it takes forever to download..

Any ideas on what I did do wrong?
[Galaxy Tab 4 Q&A, Help & Troubleshooting] sub77:
you need 2 configs or a patch.

$ make mrproper

$ make ARCH=arm msm8226-sec_defconfig VARIANT_DEFCONFIG=msm8226-sec_matissewifi_defconfig

$ make menuconfig (or xconfig, gconfig )

$ make all

if finished copy the modules devicetreeblob, get a initrd matching your rom and make a boot.img.

i prefer building with a build environment like cyanogenmod, but you can find good build scripts, too.

for kernel compiling you can use a 4.9 toolchain.
[Galaxy Tab 4 Q&A, Help & Troubleshooting] amyren:
Thanks for the reply.

I manage to make it compile, but I dont know about the devicetreeblob and initrd.

So I did the steps that you advised.

But I noticed some messages on screen refering to the path of the 4.7 toolchain, so I just tried to do it by the way mentioned in the guide, but using the .config file generated by the command 'make ARCH=arm msm8226-sec_defconfig VARIANT_DEFCONFIG=msm8226-sec_matissewifi_defconfig'

Now I did a zimage file, and I used the zimage tool to recreate a new boot.img file from the one I was currently using (stockless).

I replaced the boot.img in the rom with my new one.

And the result, was kind of what I was expecting... The rom doesnt boot, but goes into download mode instead. So I have reinstalled my the stockless again.

My goal was to try to compile a kernel suitable for overclocking. I'm on the stockless rom (4.4.2), and I wanted a try the new kernel there.

I will attach the source files I have modified for the overclocking, you can take a look if you want.

And if they look ok, it would be even better if you could compile them into a working kernel.

regards

edit: I also attached the boot.img file from the stockless v5 rom

[Galaxy Tab 4 Q&A, Help & Troubleshooting] amyren:
Thanks, where can I get that file, and how can I apply it?

It was not mentioned in the guide I was using

edit: found out that I need something called the dtbtool in order to create the dt.img

I found an archive with that tool inside, but I'm not sure if this is a universal tool, or if there are different variants for different hardware.

And then I will need the intrd.img, I still need to figure out how to get that.
[Galaxy Tab 4 Q&A, Help & Troubleshooting] sub77:
its universal. look at mkbootimg.mk located in any cm device tree.

---------- Post added at 07:22 AM ---------- Previous post was at 07:21 AM ----------

extract your roms boot.img and take its ramdisk.
[Galaxy Tab 4 Q&A, Help & Troubleshooting] amyren:
Thanks. However, it seems like every answer I get generates new questiones :)

Using a spilt tool, I got the ramdisk extracted, resulting in this file: boot.img-ramdisk.cpio.gz

That file is about 1.5MB, is this the correct file, and I can just rename it into intrd.img?

Or... if I extract it I will get another file at 3.5MB, named boot.img-ramdisk.cpio

Then I copy the dtbTool to my kernel source folder and run this command, and get the following output with an error:

./dtbTool -o ~/dt_files/dt.img -s 2048 -p ./scripts/dtc/ ./arch/arm/boot/

Generating master DTB... error writing output file, please rerun: size mismatch 583680 vs -593

EDIT: It turned out that all I needed to do was to go to the root folder and create the folder dt_files first. But I must say that error message was far from helpful: "size mismacth". But anyway I've got my dt.img file now. Next thing is to locate the tool an dfigure i\out how to use it to create the boot.img file.
[Galaxy Tab 4 Q&A, Help & Troubleshooting] amyren:
Finally, I managed to put together a boot.img file and packed it into a rom.zip and it actually boots.

Didnt notice much to my changes though, so I need to study some more..

Hi :)

Thanks for writing to us at XDA Assist. Unfortunately it looks as though you've gone against the great advice you were given by one of my experienced colleagues in this thread, and now you're stuck in a situation where you may not be able to recover fully. I'm not sure why you'd do that, you came to XDA Assist looking for the advice of experts, and you were warned about what might happen.

There is no dedicated device section for this phone so coming across the stock modem is going to be difficult to say the least. I'd suggest you do your darndest to search for what you need, but your chances are pretty slim. You could always ask your question in the general q&a section if your searching doesn't prove to be fruitful.

I accidentally deleted some important conversations from my Whatsapp on my Galaxy note 4 and iam trying to find out if its possible to restore them. I went to my root folder to whatsapp/databases and inside there are encrypted files, each one of several kb,of my conversations for example: msgstore.db.crypt8. I even sent these files to my email to have them available in the future. So my question is if its possible to open there files somehow? Thanks.

Hi,

a have installed LVSW Edition (2007/04/08) and the CPU usage is everytime (idle) at ~50%. Tested it after a Hard Reset and only install this Task Manager: http://www.iaccarino.de/silvio/ppcstuff.htm

I never had this problem before - in every ROM the CPU usage is at 1-2% at idle.

[8525, TyTN, MDA Vario II, JasJam ROM Development] johnburn:
http://xdaforums.com/showthread.php?t=284974&highlight=Sleuth255+A2DP+fix

Sleuth255's fix was to create a service that emulates the continuous idle priority loop that a certain TaskManager was using to determine how busy the CPU was. The side effect is that to task managers, it appears that the CPU is busy, because it is processing this service's loop when it is "idle". Sort of a "Catch 22".

There was some discussion when the fix came out as to whether this would have a negative effect on battery life. In my non-scientific testing, it did, but others said no. I don't actually use the fix myself, I just load the TaskManager in question and keep it in the background while listening to music, then close it when I am done. Only works well if you do this soon after a soft reset. Once RAM gets cluttered with DLLs etc. the workaround becomes less effective (especially if you have use the phone in the meantime).

Hi,

I've just bought the Nubia Z7 Max.

I see that there is a small square pad on the inside of the battery cover that connects to two contacts on the phone.

What are they for? I'm assuming some sort of antenna, although I don't see any drop in wifi/3g signal when the cover is off.

Could it be bluetooth or gps antenna instead?

[Galaxy Note 4 General] tmac31:
Yes it improves graphics performance in benchmarks but it doesnt effect games. Cuz pretty much all games support 1080p most so games already has performance improvement without anything.
[Galaxy Note 4 General] turbomann:
Ok. I understand. I edit tittle post. Android seems to be more faster with this resolution. Recent apps loads faster comparing to 2k resolution.

I try a few days.
[Galaxy Note 4 General] Tom540:
If I could make a slight correction, 2k is technically 1080.

4k and 2k refers to the largest of the two resolution values; 3840 x 2160 gives us 4k (3840 is approx 4000) and hence 1920 x 1080 gives us 2k (1920 is approx 2k)
[Galaxy Note 4 General] tmac31:
Yes it can affect ui performance more than games. Ui has higher res. If you set everything to lower res cpu and gpu wont have to work hard like they are on 2k res.

[Galaxy Note 4 General] Krokogator:
So 1440x2560 (3,7mln pixels) is same as 1080x1920(2mln px) "technically"?
[Galaxy Note 4 General] bnghty:
in the real world, lowering the resolution from 2k to 1080p would give a big improvment in performance and battery life.

however after finding out about this trick a few weeks ago and reading more about it- the difference in battery life is negligible as the screen still powers the extra pixles, however the only difference is that the gpu doesn't have to process them.

you can use it for the extra score in antutu, but it doesn't give you much as apart from that..I haven't encountered a game/app/anything since my S4 that lagged. and especially not on my note 4.
[Galaxy Note 4 General] Tom540:
No; if we are being pedantic, 4k should be called 3.84k and 1080p should be called 1.92k.

However, if we round 3.84k to 4k then we should clearly round 1.92k to 2k.

QHD is actually 2.56k, although that's too far from 3k to round up and too far from 2k to round down. MKBHD discusses it in his video "Oppo Find 7 Rant!" - http://youtu.be/E0_JrUNevdc
