[KERNEL] [Q] N9600 klabit kernel - Samsung Galaxy Note 9 (Snapdragon) ROMs, Kernels,

[KERNEL] [Q] N9600 klabit kernel - Samsung Galaxy Note 9 (Snapdragon) ROMs, Kernels,

As most of you guys know Magisk will not work for us on the international snapdragon S9, S9+, and N9
So, I have made a custom kernel that will allow us to have root on stock pie firmware..
Files needed:
N9600:
klabit kernel V6.5
FK Manager n9600 kernel download configuration link
FK Manager n9600 GSI kernel download configuration link
Copy the n9600_q_vx.zip to your external sd card.
Make sure you have TWRP installed with instructions found in this thread.
Flash the n9600_q_vx.zip
Flash Magisk (only necessary if you have not flashed Magisk previously or if coming from a clean install from stock)
Reboot to system.
If you currently do not have a working lockscreen/pin/fingerprint setup, you will need to restore your stock boot.img either via backup or extract your boot.img from the official firmware and flash the img then flash my kernel.

I don't understand what you mean.
This is an updated pie kernel.
I haven't made anything for pie on the note9 before.

It feels so good to be rocking pie rooted on the n96000. Kinda hilarious because i went and purchased an n960fds last month to get pie/root. I no longer have to live without google camera as it doesnt work on eynos .Thanks alot!

Thank you so much @klabit87 for your continued support of this amazing phone

@klabit87 Thanks a lot for the kernel. I just wonder if after flash, something get lost.. for example encryption.. Samsung health.. or any knox crap dependencies.. Thanks!

Anytime you trip Knox when you unlock your bootloader you will loose something. Encryption is an option and a choice.
Health and whatnot can be fixed but the kernel is not responsible for it.

I successfully compiled kernel with my needed modules, however when using "anykernel" to flash to device, all good except NO WIFI.
I also used the "tar-Tool_Odin3-v3.10.7_by_mkh.mourad" used pulled boot.img from phone to test if tar-tool worked for me and wifi worked, then replaced my compiled Image.gz-dtb , everything works but no wifi.
I pulled proc/config.gz from my working wifi device
then renamed to config_defconfig
then compiled
ran thru tar-tool ,converted to md5.tar
flashed with odin
Works as before NO WIFi
EDIT: Is it possible Magisk has something to do with the kitchen not repacking everthing into new boot.img?
Going to try to repack using magisk tools..
Any sugestions would be helpfull

I meant to respond to this earlier but no magisk isn't breaking wifi. You need to export a couple of variables before compiling.
Code:
export ANDROID_MAJOR_VERSION=p
export PLATFORM_VERSION=9.0.0
add those to your build script or just run them manually before running your build script and the wifi drivers will be included properly.

In light of the most recent update to FK Manager see here for details ------->> https://twitter.com/franciscof_1990/status/1215673739435704320?s=20
I have added support for the kernel download configuration which will allow you to update directly within the app. It will also notify you when an update is ready.
Check the OP for the links to the configuration.
Just copy the link address and paste into the "Import a kernel download configuration" box and done.
You can remove and add different ones if you want as well.

Also wanted to note that I will still post the updates in the OP. I am not going to make the updates only available through the app.
With that said, V5.8 will drop today

New minor update to v5.9.
This will make using gsi and most up to date/latest firmware versions much easier and more compatible.

Sorry I was away,
Yes it went perfect. Thank you.
However since android 4.4 I have compiled kernels and modules with ease.
I really don't have the time to commit to my hobby(Debian on Android) like I used to, so my reading and experience has slipped a bit.
Now I read Android 8.0 and up have "Modular Kernel splitting the device kernel into a system-on-chip (SoC), device, and board-specific deliverables ".
For reasons "ensure a workable booting system remains on the disk during an over-the-air (OTA) update. This approach reduces the likelihood of an inactive device after an update, which means fewer device replacements and device reflashes at repair and warranty centers" as explained here: https://source.android.com/devices/tech/ota/ab_updates.
Well that's all fine but I still cannot figure out how to tell the system upon bootup to load a specific module. How would I load the module from adb or terminal. The older way ,depmod -a , insmod , modprobe, seems to have no effect with android 8 and up.
I have successfully built modules with:
CONFIG_MODULES=y (and not with...CONFIG_MODULES=m)
CONFIG_MODULE_UNLOAD=y
CONFIG_MODVERSIONS=y
After flashing kernel, I can see the module folders under /sys/module and within that folder is another, "parameters" and an empty "uevent" file. Within the "parameters" folder is a file "oom_pages" the content is "256"
So how would I load say "virtio"
The old way would work:
1st: depmod -a
2nd: modprobe virtio
Not working with android 8
By the way Im using ubuntu 16.04 image mounted here: mount -t ext4 -o rw,noatime /dev/block/mmcblk0p2 $mnt
$mnt=/data/local/Linux
As a side note: I like to play around with qemu , virt-manager, (windows-xp runs fast enough to be usable with this snapdragon)
and I can run full Minecraft , haha.

I haven't messed with modules in a long time. I just include what I want in the kernel instead of building modules lol.
I would have to do a little investigating to find the answer you're looking for tbh.
But that's awesome that you can run such different software on your device, mainly the qemu stuff.
If I recall correctly, you need to allow unsigned modules to be loaded as well as remove lkmauth from the kernel.

Kexec-hardboot patch

In this post, I would like to explain what kexec-hardboot patch is and also bring it to light a bit more since until now, it was only burried in MultiROM thread.
@kernel developers: I would like to ask you to merge this patch to your kernels, because it is essential part of MultiROM - it allows me to boot any kernel without changing the boot partition. I realize that it is no small request, but the patch is not big, touches relatively stable parts of kernel and should not cause any problems. Thank you.
What is kexec?
It is syscall of Linux kernel, which allows you to boot another Linux kernel without restarting the device - "Linux boots itself". The functionality is equivalent to fastboot -c *cmdline* boot zImage initrd.img, but without PC and fastboot. It is fairly known thing, so more info at wikipedia and man kexec.
Standard kexec call unfortunatelly does not work on Nexus 7. It freezes somewhere, and it is very difficult to find out where - probably some of the drivers are not shut down/re-initialized properly, it is a commong thing among Android devices, which is why kexec-hardboot was made.
What is the difference between normal and hardboot exec?
Kexec-hardboot patch adds a real device restart to that process, so that all the drivers can be properly reinitialized. It stores new kernel to RAM, reboots the device as usual, and kernel from boot partition immediately jumps to the one which was stored to RAM before reboot.
Another difference is that both kernels must be patched. The "host" kernel requires a full patch, the one which is being kexecd' requires only two small compatibility patches.
To sumarize the process:
kexec --load-hardboot.... is called and kernel it loaded into RAM.
kexec -e is called. Special info is written to memory (to area which is not overwritten on reboot) and the device is rebooted.
After reboot, very early in the boot process, kernel checks if that special info is present in RAM and if so, it loads new kernel from RAM and jumps to it.
Kexecd' kernel starts and boots.
For more info, read the original thread.
Patches:
Full kernel patch: https://gist.github.com/4558647, 4.1 kernel repo, cm 10.1 kernel repo
This is the full kernel patch. Kernels with this patch can be both "host" and "guest" kernels.

First three options must be enabled. Last one, GROUPER_HARDBOOT_RECOVERY, specifies if the kexec call should reboot to normal mode or to recovery. This can be useful if you don't have the kernel in boot partition but only as kernel in recovery partition. You usualy want to disable this option.
Compatibility patch: https://gist.github.com/4458581
This patch only makes the kernel bootable via kexec, ie. it can't be the host kernel. This was made for Ubuntu kernel (and it was accepted), because I did not want to drag the whole patch in there. If your kernel is for Android ROMs, you should use the full patch.
Userspace kexec binary: View attachment kexec-tools.zip
That ZIP file contains kexec source, patches and README. It is from the original patch from Mike Kasick. It also contains precompiled, statically linked kexec binary, so you probably just want to use that.
Usage:
Once you have the kernel patches and kexec userspace binary in place, just run following command to boot into new kernel:
Code:
kexec --load-hardboot zImage --initrd=initrd.img --mem-min=0x85000000 --command-line="$(cat /proc/cmdline)"
kexec -e
Note the command line parameter - cmdline from bootloader is not added automatically, you have to put it there by yourself.
Currently used by:
MultiROM - I use it to boot different kernels (eg. Ubuntu).

Authors:
This patch was made by Mike Kasick for Samsung Epic 4G. Since that, it was ported to several devices, one of them is Asus Transformer TF201 - I used patch from TF201 and modified it a bit (basically just changed few SoC specific constants). People at #ubuntu-arm helped me out with that, thanks.

Hi Tasssadar,
im trying to get this to work on the HOX in order to have a shot at multiboot,
the patched applied with no problem... however on compiling i gett this error
"Adress for kexec hardboot page not defined"
ask this error naturely defined to kick in with every device beside N7 i that comment completely....
and that ended up giving me an error about KEXEC_HB_PAGE_ADDR not defined,
so i readded it, but i removed the "#if defined(CONFIG_MACH_GROUPER)"
now trying to compile it, its gets pretty close to the end... but failed with unexpected string error at line OUTPUT_ARCH(arm) in file linux/arch/arm/boot/compressed/vmlinux.lds

I'm afraid "comment everything which doesn't work" won't work here. The KEXEC_HB_PAGE_ADDR and END_MEM is device-specific, it will most likely be different for HTC One X. You can find out what address is it supposed to be by examining /proc/iomem on your device. For example, here's memory map from grouper:
Code:
...
80000000-be9fffff : System RAM
80008000-808faba7 : Kernel text
80940000-80b8228f : Kernel data
beb00000-bebfffff : ram_console
...
So, for grouper, END_MEM is 0xbe9fffff + 1 = 0xbea00000.
KEXEC_HB_PAGE_ADDR is located 1MB before console RAM, which is in this case also immediatelly after System RAM, so for grouper, it is also 0xbea00000.
but failed with unexpected string error at line OUTPUT_ARCH(arm) in file linux/arch/arm/boot/compressed/vmlinux.lds

That doesn't seem to be related to this patch. Are you using correct cross-compiler?

aaaa would it wok if i used the address before??

Edit:
or did your ram RAM end earlier because you set you END_MEM 0xbea00000
in that case, it works out just the same with the HOX

i would have guessed so, but the kernel compiled and is working before the patch.
im using the one provided by google (Android NDK r9) while it contains booth gcc 4.6/4.8 im using 4.6 (arm-linux-androideabi-)

The patch will move ram_console 1MB further, see https://gist.github.com/Tasssadar/4558647#file-n7_hardboot-diff-L387 . You'll have to modify this part of the patch, it will be in different file for your device.

HOX is also a Tegra 3 device... so im guessing i wont need to touch a thing?
also note... that iomem provided is from an unpatched kernel (as i cant compile a patched one)
also,
im currently on freenode #htc-one-x
if you dont mind joining.

I've been looking through the kexec-hardboot patch these last few days, trying to actually understand it instead of just blindly porting it and after several hours of messing with assembler with no means to debug it, I've managed to remove the need for guest kernel to be patched. This is not really useful for grouper, since thanks to multirom and accepting kernel devs, nearly every third-party kernel has the proper patches. But, if I'll port multirom to some other device (hello, flo), it will be very useful
To know more see the changes in this commit, but you'll probably need to understand how the patch does things: https://github.com/Tasssadar/androi...mmit/2ce4130061f72430a8ddfde25346c4e528c5c30b
@mkasick: Could you please look over this? I'm afraid there's some good reason why you didn't do this in the first place, like rewriting some part of memory which shouldn't be rewritten or something like that. Thank you.

Perfect timing, just finished my last exam
Edit:
Also, this applies on top of the original patch right??
Edit2:
i can't seem to get it to kexec boot, but i didn't do much testing, maybe 2morrow night!
Edit3:
fixed, it was a problem with min-addr,
changed it to 0x82000000 and it worked

One more question...
TEGRA_PMC_BASE is also device specific, ain't it???
So, for a Qualcomm device, what should I be using? I am guessing it is MSM_RPM_BASE, which I got from here: http://forum.xda-developers.com/showpost.php?p=31127486&postcount=7

Yes, it is SoC-specific. This is using some special register to reset the chip, I'm not sure if that is available on msm chips - probably yes, but in some different form. Your best chance is to examine restart sequence in arch/arm/mach-msm/restart.c and port it to assembler.

The address of 0xA0000000 is not necessarily the best choice going forward. It originally made perfect sense, as it is well above everything else. But now that we can boot unpatched guest kernels, we can hit the interesting situation where the guest decompression may take a full minute. At least it's when I've seen on the Ouya game console that's running the next chip after Grouper.
When I realized what's going on, I changed to 0x8E000000, as it gets me just below the 256 MB limit of cache-enabled memory that's present on a typical guest at that early decompression stage. It's enough to hold a typical 8 MB boot image kernel/ramdisk. Now the guest kernel startup is fast in all cases.
Thank you Tasssadar for continuing your work in this area, especially with finding that way to allow unpatched guests.

Indeed, that's actually what I'm using in MultiROM for flo and mako (and grouper, but it is useless 'cause not all 3rd-party kernels have been updated), I just kinda "forgot" to update these threads.

Would it work on devices with locked bootloaders (Xperias). I mean :does the idea of this patch would also work on bootloader unlock allowed :no devices?
Sent from my LT22i using xda app-developers app

I am trying to build a kexec patched kernel integrated into a ROM. I make sure that the following code is there in the defconfig:
CONFIG_KEXEC=y
CONFIG_KEXEC_HARDBOOT=y
CONFIG_ATAGS_PROC=y
The ROM works well, except that it does not boot my secondary ROMs - kexec hardboot patch missing. I have multi ROM and TWRP recovery installed
What am I missing?

Logs or it didn't happen.
Show me dmesg from normal boot into android, with MultiROM and your kernel installed.
Code:
adb shell
su
dmesg > /data/local/tmp/dmesg.txt
exit
exit
adb pull /data/local/tmp/dmesg.txt

Porting?
Tassadar which things do I need to boot kexec kernel on my device (Motorola Electrify 2) .

@Tasssadar, Sorry for picking up this kinda "old topic" but I'm sadly experiencing some problems while trying to port kexec-hardboot to the Sony Xperia Z2 (aka sirius). I applyed all needed commits (cherry-picked from a apparently working Z1 repo for stock kernel) to my CM based custom kernel (https://github.com/Myself5/android_kernel_sony_msm8974/tree/kexec-cm-12.0) and it does not boot at all. It's stuck on the Sony Logo, and it seems like I can't get any log either. I also tryed the stock cm kernel with the patch (https://github.com/Myself5/android_kernel_sony_msm8974-kexec) cause I tought it might be some incompatibility, but sadly it wasn't. Hope you have any ideas to solve my problems, cause I'm out of ideas ATM. I also checked the kexec commits for other devices (namely the One Plus One) and it seems like I got everything needed.
Thanks in Advance

Tasssadar said:
In this post, I would like to explain what kexec-hardboot patch is and also bring it to light a bit more since until now, it was only burried in MultiROM thread.
@kernel developers: I would like to ask you to merge this patch to your kernels, because it is essential part of MultiROM - it allows me to boot any kernel without changing the boot partition. I realize that it is no small request, but the patch is not big, touches relatively stable parts of kernel and should not cause any problems. Thank you.
What is kexec?
It is syscall of Linux kernel, which allows you to boot another Linux kernel without restarting the device - "Linux boots itself". The functionality is equivalent to fastboot -c *cmdline* boot zImage initrd.img, but without PC and fastboot. It is fairly known thing, so more info at wikipedia and man kexec.
Standard kexec call unfortunatelly does not work on Nexus 7. It freezes somewhere, and it is very difficult to find out where - probably some of the drivers are not shut down/re-initialized properly, it is a commong thing among Android devices, which is why kexec-hardboot was made.
What is the difference between normal and hardboot exec?
Kexec-hardboot patch adds a real device restart to that process, so that all the drivers can be properly reinitialized. It stores new kernel to RAM, reboots the device as usual, and kernel from boot partition immediately jumps to the one which was stored to RAM before reboot.
Another difference is that both kernels must be patched. The "host" kernel requires a full patch, the one which is being kexecd' requires only two small compatibility patches.
To sumarize the process:
kexec --load-hardboot.... is called and kernel it loaded into RAM.
kexec -e is called. Special info is written to memory (to area which is not overwritten on reboot) and the device is rebooted.
After reboot, very early in the boot process, kernel checks if that special info is present in RAM and if so, it loads new kernel from RAM and jumps to it.
Kexecd' kernel starts and boots.
For more info, read the original thread.
Patches:
Full kernel patch: https://gist.github.com/4558647, 4.1 kernel repo, cm 10.1 kernel repo
This is the full kernel patch. Kernels with this patch can be both "host" and "guest" kernels.
Related CONFIG options:
CONFIG_KEXEC=y
CONFIG_KEXEC_HARDBOOT=y
CONFIG_ATAGS_PROC=y
CONFIG_GROUPER_HARDBOOT_RECOVERY=n
First three options must be enabled. Last one, GROUPER_HARDBOOT_RECOVERY, specifies if the kexec call should reboot to normal mode or to recovery. This can be useful if you don't have the kernel in boot partition but only as kernel in recovery partition. You usualy want to disable this option.

I'm sorry for picking up this older topic as well, but I always played with the thought of merging kexec support into a kernel and I'm doing one right now.. But my secondary device is a LG G2 and since the era of Lollipop began, somehow MultiBoot just stopped working and nobody can figure out why. I think they even started to build some new concept now.. So before I spark a heated debated by Note 4 users I'd love to know if you have any idea if this patch is still applicable? Altough the only way to find out is to probably just try it lol.

Bro can you please mention on your wiki that kexec isnt supported for x64 devices? It will be great help and save developers hours! I was porting for oneplus 2 when a dev told me that kexec isnt there for x64. I was shocked
Is any alternative available for that? Please reply! Thanks.
All other devs, who cant make multirom to work (lollipop is the x64 era) stop working. Kexec isnt supported for x64. Find an alternative for it.

Can Anyone help me to port this? Here is my patched kernel (ignore arch/arm64) and this is /proc/iomem.
Code:
80000000-854fffff : System RAM
80008000-80fa43ef : Kernel code

9ff80000-9fffffff : persistent_ram
a0000000-ffffefff : System RAM
For kexec_hb_page_addr the value i inseted is 85500000 coz as tasssadar said 884fffff + 1 = 85500000, but I don't know what value add for
Code:
#elif defined(CONFIG_ARCH_MSM8916)
/* Restart using the PMIC chip, see mach-msm/restart.c */
ldr r0, =MSM8916_HARDBOOT
mov r1, #0
str r1, [r0, #0]
loop: b loop
MSM8916_HARDBOOT, and if I compile the kernel it stucks on samsung logo.

Although my original intention was just to help with porting CM 13 to i9305, I ended up with my build
To avoid any confusion a because I still have a felling that some people don`t understand this, I have to explain one more detail. I didn`t create this, I only built it. It is a big difference, similar to buying versus building a house. Buying a house is not a simple thing (at least in my country) and you`d probably need to do some changes and repairs before you can start living in it. But building a house is something completely different and much more difficult. The work I`ve done on this CM build is more like buying a house. The see the list of people who "built the house" go into Settings on your phone, section About phone and then Contributors. It is a really long list. Thanks to all of them
Also, please, keep in mind, that I am only sharing results of my hobby.
It is build mostly directly from CyanogenMod 13.0 sources. I only added support for i9305 and cm12 chroot for RIL support. See the original thread for some details. Anyway my work on this is really small, I fixed some problems a put all of this together.

Multiple RIL implementation
In this ROM, there are more then one RIL implementations. None of them is perfect, but you can choose, which one of them works better for you. The first RIL implementation is the usual CM 12.1 based one (this is the default one), the second one is based on proprietary files extracted from stock 4.4.4 ROM downloaded from sammobile.com (I9305XXUFOB2_I9305PHNFOB2_I9305XXUFOA1_HOME.tar.md5), the third is based on proprietary files from TheMuppets, with one small change (see here for details). To switch between them open shell (over adb, or using the build in app, or whatever you like) and execute command ril. You will see something like this:
Code:
Select RIL implementation:
* 1 - CM 12.1 based
2 - Stock 4.4.4 based
3 - TheMuppets based
x - quit
?
Type 1,2,3 or x and hit enter. The requires root, so be sure it is enabled. After switching, reboot the phone. If you don`t want bother with this, don`t. The default one is, based on my experience, the best
If you want gapps, use http://opengapps.org/. As mentioned several times elsewhere flash it RIGHT AFTER the ROM. I tried the nano version and it works fine.
As far as I know all hardware and RIL is working without problems (even barometer is correctly detected).
Know BUGs:
- sometimes after boot RIL is not started correctly (http://forum.xda-developers.com/galaxy-s3/development-i9305/rom-t3252492/post64740417#post64740417) - data connection (and maybe something else) is not working. In that case turn on and of flight mode (or go somewhere without signal). I trying to fix this, but it is difficult.
- the led flash light used as a torch goes off together with the display (http://forum.xda-developers.com/galaxy-s3/development-i9305/rom-t3252492/post64699946#post64699946)(fixed http://review.cyanogenmod.org/#/c/132783/)
- I suppose there is still msm_hsic_host wakelock bug (https://jira.cyanogenmod.org/browse/CYAN-2266). Supposedly unplugging the charger with display on should prevent this. EDIT (13.2. 2016) Some people are reporting that is fixed. I didn`t anyting specific to fix it, so I am not sure. One possibility is that this was also caused by the clock bug.
- if you have non FAT partition on you sdcard, you get a message that sdcard is corrupted. I`ll try to fix this one, it should not be difficult and it is annoying for me.
- gallery app is crashing for non owner (EDIT 19.1. 2016) (EDIT 17.2. 2016)
- there a problem with bluetooth audio - it occasionally stops for few seconds may be fixed in the today`s build (EDIT 1.2. 2016)
- on the first boot (after /data wipe) the SIM may not be found. Reboot should fix this. (EDIT 31.3. 2016)
Selinux is enforcing. If you used some of my previous builds from the original thread and there is something broken, what worked before, this may be the reason. In that case output of dmesg | grep 'avc.*denied' from the moment the problem happens, is a big help to solve it.

This is definitely not the only way how to build CM13 for i9305, but it is the procedure, which I, more or less, use.
First of all read (and understand) the original guide. My build process is modified version of it. The modification is necessary, because there is no official CM13 for i9305, so the breakfast command won`t work. It is replaced by creating .repo/local_manifests/roomservice.xml file. Another change is that proprietary file are part of my github repo, so you don`t have to connect the phone.
Followe the guide mentioned above till the repo command setup. The next step is to initialize the CyanogenMod source repository - use the cm-13.0 branch:
Code:
$ cd ~/android/system/
$ repo init -u https://github.com/CyanogenMod/android.git -b cm-13.0
Now before you do repo sync, you have to create the roomservice.xml file (note the actual command is old, download the latest .tar.gz archive attached to this post and extract roomservice.xml from it):
Code:
$ mkdir .repo/local_manifests
$ wget "http://forum.xda-developers.com/attachment.php?attachmentid=3657032&d=1456237857" -O .repo/local_manifests/roomservice.xml
Now is time for downloading the code (it takes some time):
Code:
$ repo sync
After this is done you will probably need to sync the code from my github with upstream. It may up to date, but i can`t guarantee it. First add the upstream repo:
Code:
$ cd ~/android/system/system/core/
$ git remote add upstream https://github.com/CyanogenMod/android_system_core.git
And now sync the code:
Code:
$ cd ~/android/system/system/core/
$ git checkout cm-13.0
$ git fetch upstream
$ git merge upstream/cm-13.0 -m 'sync with upstream'
The checkout is necessary to have cm-13.0 branch active. Following two commands download the code from upstream and merge it. They can be replaced with one pull command. Now apply patches. I usually attach them either to this post, or the post, where I announce something new (like a fix). The reason why I share some changes this way, is that I don`t wan`t to fork whole big repository because of a small change. In the latest (cm-13.0-20160217-UNOFFICIAL-i9305.diff) diff there is only one change bigger than one line - delete 5 lines (2 of them are comments). This is usually easy to change manually, if patch fails. You can use this https://groups.google.com/forum/#!topic/repo-discuss/43juvD1qGIQ to apply the patch (store the script into ~/bin/repo_patch and make executable).
Code:
$ cd ~/android/system/
$ repo_patch cm-13.0-20160217-UNOFFICIAL-i9305.diff
Now proceed to the Extract proprietary blobs step. The commands are the same, but you don`t have to connect the phone to the computer:
Code:
$ cd ~/android/system/device/samsung/i9305
$ ./extract-files.sh
Since you skipped the breakfast step, you should now return to the ~/android/system/ directory and setup the environment:
Code:
$ cd ~/android/system/
$ source build/envsetup.sh
Now setup the ccache, if you want. See Turn on caching to speed up build in the original guide.
Start the build:
Code:
$ brunch i9305
If you find some problem let me know, I can try to fix it. But I can`t promise anything, this is only hobby for me and my original intention was just to help with porting CM 13 to i9305.

The bug whit the flashlight is on every CM12.1 rom.
2 min using the flashlight and the phone automaticly booting (bootloop).
Is there a chance the problem whit the sdcard to be permision problem?
Thanks i was start thinking that no one want we to have a marshmallow rom for our devices. Live long and prospect.

I don`t think so. I suppose that this is because there is ext2 partition (with Debian chroot) and Android has never designed to use sdcard with something like this. Until this version it was simply ignored. It is not a big problem, just annoying message.

Edit your post please. No need to quote entire OP

@p.a.n gongrats for your first and the new thread with your rom and many thanks for uploading your sources.
But I am wondering, why you haven't pushed the changes in build and smdk-common, which are present in your posted diff file? Are they not needed (anymore?). And still not clear is, where to put mount_chroot.sh? In system/bin or cm12chroot/system/bin?

ok ... I tried it with usual cyanogenmod smdk-common cm-13.0 branch and original cyanogenmod build and without mount-croot.sh and: sim card and ril is working. But I still cannot hear something or anybody during a call . What vendor/samsung repo are you using? themuppets or crazyweazel and which branch? Maybe there is the problem located?

All the my changes from smdk-common are either in upstream (e.g. the incomminmg call fix) or I moved them to i9305. Script mount-croot.sh is not necessary anymore, the mounts are handled by init (init.target.rc). The only changes from the diffs which are not in those two repositories were in kernel and they are not necessary. The proprietary files which I am using are in the repo (https://github.com/p-an/i9305-cm13-device/tree/cm-13.0/proprietary, https://github.com/p-an/i9305-cm13-device/blob/cm-13.0/cm12chroot/cm12chroot.tgz), I don`t remember where I have it from Just execute extract-files.sh in device/samsung/i9305.
I really have no idea what could be wrong in your case You problems with audio or is it the still the problem with incoming calls (the phone doesn`t ring when someone calls)?

p.a.n. great work brother, installed this ROM with this Gapps (https://www.androidfilehost.com/?fid=24269982086993883) with my outdata Philz Touch 6.48 and works pretty damm good! GPS and wifi OK, incoming and outcoming calls smooth. Congratz!!!

Im expirience a slow charging whit your Rom whit agni kernel. Before that i was on Acip10 whit the same version of agni kernel and the charging work corectly. Hope im helpes.
Oher bugs: trebuchet crashing, skype is not working.

@p.a.n thanks for your all you've done,the rom works great for me,ril data 3g and lte works fine,many thanks ......

@rodman01 just and idea, you`ve probably tried it - do you have data connection, when you try the call? The bug which requires airplane mode on/off effects more than only data connection - if it happens also Llama doesn`t correctly detect area based on cell id. So it could be the reason for your problems.

Could you provide some details - how to replicate it, logcat, etc. ? Trebuchet seems to be stable to me, but I using mostly another launcher. I don`t use skype, so I am afraid I can`t help with that one

Many thanks for the the tip, I will look at it and make some tests. Sim and ril is working, incoming and outgoing calls too...but no call audio, so I cannot hear the caller and he doesn't hear me neither.

Can you talk on a headset via the 3.5mm jack? If you can then it's related to RIL or the microphone and earpiece don't work in call.

In AGNi control set 'Ignore unstable charging power', 'ignore safety margin', 'AC charge rate 1500mA'.
You won't damage anything, not phone nor charger.
There is a free app called Galaxy Charging Current which shows you the charging rate.
If you're too scared, just do the ignore unstable power and that will cure your issue. The other two things just make it charge even quicker.

- Several other patches to reduce battery usage
- Multi-core scheduler enable/optimized
- APM driver updated reduce battery usage during sleeping
- Fix the wake up time. The screen should wake up more quickly when pressing the button.
- Tweaked the scheduler to reduce/save power by scaling down the frequency of the CPUs or idling them,
- A lot subsystems converted to use power efficient workqueue
- The watch goes to sleep during no action in order to save battery
- Remove debug event logging-Kill the useless logging to reduce overhead
- Remove sync debug entirely to cut down CPU waste in the frame render hot path
- Remove 10 ms CPU idle latency unvote timeout- Doesn't force the CPU to stay out of deep idle states for far longer than necessary, which wastes power
- Disable audit support, usually comes with a measurably significant amount of overhead
- Remove audit dependency

Link are fixed now. It will properly not gonna work on non-lte. I can build a new for non-lte version if some one send me the latest system image and boot image. (I can extract from your watch via teamviewer, in case you can't) But you need to flash the latest firmware without root.

I will upload a complete latest stock images N7176C (lte) incase anyone wanna go back to latest stock again.
The only thing you have to do is boot into bootloader mod and then run the script by double click on it. After some reboots you will be back on latest stock.
I will combine both Linux and Windows together, use one you prefer.

Just received my Huawei SW 4G this weekend and after installing Huawei wear I got the alert message that the watch was rooted.
How can I confirm is it's rooted or not.
Thanks

Can anyone who's used this verify that it's notably faster or has improved battery life compared to stock? Or is the difference negligible?

How to build boot.img
Hi Janjan,
I am trying to build a custom kernel for my Huawei Watch 2 (non LTE) and I was wondering if you could share a little of your development work.
How do you actually put the boot image together? I am able to compile the kernel from android-msm-sawshark-3.18-nougat-mr1-wear-release,
which gives me a zImage. I also have the original images. So I tried to unmkbootimg the original boot image and replace the kernel. However, this doesn't seem to work. when I compare the sizes of the supposedly original zImage and the one created from the repository above, their size differs by roughly a factor of 100. So there must be something seriously wrong
What steps do you use to create the kernel and the boot image?
I also checked your github code and tried to use it but it seems to depend on other stuff that is not in your repos. Where did you find the code you have in your repos?
Best regards,
Mogli

Hi Janjan,
(Apparently I am not allowed to post links yet, so I am trying my best to explain without them)
1. I got the source code for the Sawshark watch from github (mr1-wear-release). I guess there is no dedicated Seafish kernel source. Short question: There is a choice of 3 different kernel codes. Which one shall I take?
2. I tried to compile this source code without changes (to rule out errors before I make modifications). This works and I get as zImage. What do you mean by modul though? I thought zImage was the only product.
3. Using unmkbootimg, I un-packed an stock boot.img. The unmkbootimg tool says that the boot.img has been compiled with a non-standard mkbootimg program. However the offsets and other values (I am supposed to tune when I use mkbootimg) are contradicting. Eventually, the "non-custom" values recommended by unmkbootimg caused errors in mkbootimg and I ended up using the default values. This worked.
4. When I flash the resulting boot.img my watch gets stuck during boot with the Huawei logo on all the time.
To verify my tools, I tried step 3. in two more ways:
3.1. re-pack the un-packed boot.img, flash it (no errors and boot works)
3.2 pack a boot.img using a zImage obtained from a sawshark boot.img (instead of the seafish). This also worked and boot was successful
I have also looked at the boot.img and zImage files in a hex editor. I can locate the beginning of the kernel but not the end. Also if I did, I wouldn't know how to replace the kernel in hex mode But from what I have understood about mkbootimg, this script does not much more than concatenate zImage and ramdisk and add a header. Is this somewhat correct?
Eventually, I need to turn on some currently disabled kernel features (which is why I am doing all of this ). So I am still trying to figure out the right tools and components. And therefore the question: How do you usually build the kernel and how do you pack it into the boot.img. Do you modify the ramdisk when you replace the kernel?
Best,
Mogli

Instructions to modify ramdisk
Hi Janjan,
How do you disassemble and re-assemble the ramdisk?
Wanted to make a few modifications to the ramdisk.cpio.gz. Again, I wanted to try the tools first. So I unpacked and re-packaged the ramdisk without modifications. After flashing the regenerated boot image, my watch goes into recovery mode...
I found these instructions in a tutorial (again, I can't post links yet... sorry):
For disassembly:
Code:
$ mkdir ramdisk_dir
$ cd ramdisk_dir
$ gunzip -c ../ramdisk.cpio.gz | cpio -i
for re-assembly
Code:
$ find . | cpio -o -H newc | gzip > ../newramdisk.cpio.gz
Update to my previous post:
I found my mistake in building the kernel:
Instead of using
Code:
make ARCH=arm CROSS_COMPILE=arm-linux-androidkernel-
I was using
Code:
make ARCH=arm CROSS_COMPILE=arm-linux-androideabi-

It seems much better now. Are you in Windows or Linux? I will post my script and tools once I reach my PC. I am away from my PC right now. It means you destroy something during generating or packaging the boot image. Does you kernel /boot.img work without or before editing the ramdisk?
Update:- seems you are in Linux.

Yes, I am on linux. I found a different approach that works for me now:
Code:
Extract the ramdisk.
$ mkdir ramdisk
$ cd ramdisk
$ gzip -dc ../ramdisk.cpio.gz | cpio -i
# Make any changes necessary (e.g., set ro.secure=0 in default.prop).
# Recreate the cpio archive using the mkbootfs binary produced from building the Android source code
$ cd ..
$ mkbootfs ./ramdisk | gzip > ramdisk-new.gz
You said you were able to turn on all the cores. Can this be done by modifying the ramdisk or how do you do this?

Did I said? But It can't be done by editing the ramdisk only. You need to add and edit alot (add driver edit cores etc) in kernel sources.

Okay, before anyone flames, I did look everywhere in this thread and cannot find it. Does anyone have the link to the flashing instructions for this rom?

Building kernel from Xiaomi's source for cereus (probably, cactus too)

Since Xiaomi released source code for kernel, I tried to build it.
https://github.com/Dhoine/android_kernel_cereus
Current status of this - it compiles, boots, but unusable.
Bugs:
Broken bluetooth
Broken wifi
Soft-reboots after some time
Propably, more bugs that remained undiscovered because of reboots.
Tested with miui 9 on cereus 3/32.
--------
You can test builded kernel using this:
GDrive
Use Carliv image Kitchen to repack your rom's boot.img, then flash it via fastboot (UNLOCKED BOOTLOADER REQUIRED). To restore working state after testing, flash stock boot image again.
WARNING
Our kernel uses android regular boot.img format, not MTK.
---------
If you want to build this, any manual for building kernel will fit. I used google's android arm eabi 4.9 toolchain, our arch is arm, defconfig is cereus_defconfig.
For now, I don't have enough time to take a closer look at this (work, university exams), so, any help (last_kmsg, dmesg, pull requests) will be appreciated.

Wait seriously? Does that mean that i can buil LOS rom now? I have my UbuntuVM with whole LOS source code downloaded but i got stuck at no kernel found for cereus. So it might work now(Im extremely new to linux) I'll try to build the rom asap

This kernel for now won't really help with building los. I haven't find any device tree for our SoC (or close). MTK always requre a ton of patches to android sources. But i have reference MTK 9.0 android sources for this SoC - ALPS (can't share, it's probably illegal, but you can find them on 4pda.ru, if you want). It builds on almost unmodified reference device tree, but i haven't tested it on device. First, we need to make this kernel usable.

But i have reference MTK 9.0 android sources for this SoC - ALPS (can't share, it's probably illegal, but you can find them on 4pda.ru, if you want). It builds on almost unmodified reference device tree, but i haven't tested it on device. First, we need to make this kernel usable.

This may not really help, but can you try that kernel again after upgrading to MIUI 10.2.4 ?
EDIT : See https://www.kimovil.com/en/list-smartphones-by-processor/mediatek-helio-p22-mt6762 for a list of devices with MT6762. Probably we can check out their trees?
EDIT 2 : It seems like our Redmi 6 is the only device with available kernel source in that list.
EDIT 3 : Try this?

I finally finished my university exams, so now I have some free time to play with it.
The kernel you link is just forked xiaomi sources merged to linux 4.9 kernel. It shouldn't be buildable at all, since there is the same problem in sources I "fixed" with this.
Probably, this too.

You're right, they're identical.
By the way, I couldn't find any implementation available for our Helio P22; the chipset itself is fairly new, thus not many devices have the source code available.

Ok, i've tested it on latest GS. It seems to work a way better. At least, it doesnt reboot after few seconds of usage. It makes things a lot easier.
Tested a few more things:
-sound - works
-camera (both photo and video) - works
- mobile data - works
- phone calls - work
- dual sim -works
- all sensors work
The only thing i was unable to test is gps. It didn't worked for me, but i was inside 9-floor building near the window to inner corner of building... So idk.
And usb otg - since i don't have adapder.
After this I can tell, that there are only 2 major bugs - wifi and bluetooth.
Maybe gps, fm radio and exfat too. This is modules loading problem, I think (though, there shouldn't be any modules, drivers are marked as built-in in config, but .ko files for them exist in /vendor/lib/modules)

Yeah, Treble definitely makes things easier.
Nevertheless I'm trying to integrate those kernel modules into the compiled zImage - there's no modprobe in Android, sadly.

Adding modules support and disabling modules versions check in config didn't help.
I can't find any source files in kernel sources, from which these modules can be built. Maybe, they are built from separate platform code (they are placed in vendor, so...) Need to download ALPS (brrr, around 50 gb of tar.bz2 archives) to check it.

No such code in xiaomi's source. And this prooves my words: these modules CAN BE BUILT IN and SOURCES FOR THEM ARE IN ALPS. I have to download this ton of ****...

I tried to backpors drivers from 9.0 - no success. It compiles,but doesn't boot. I tried to hack modules loading - no success too.

Most of the time those binaries are not open-source (you probably know vendor blobs for Google devices are too, but that is a different story). Nevertheless I don't really get why kernel modules are placed in
Code:
/vendor
- after all, mobile devices don't have hot-plugging hardware that requires dynamic LKM loading, why do they separate them out?
I'll attempt to crawl the web for those sources while waiting for Mi Unlock to allow my device being unlocked (the waiting period sucks).

1. Backports? How?
2. In which file did you got those lines?
3. Indeed those modules' source are removed from our tree - if you have the link, I don't really mind having another 50GB occupied on my PC to get those source code.

I already said that i have leaked mtk alps 9.0 sources These modules have sources, they are not prebuilt. I managed to built in them, but kernel doesn't boot at all after that. And i can't take any logs because the system dies before adb init.

Ok, after one little, but very cruel hack modules are fixed. Enjoy testing the kernel.

Users from 4pda reported it fully working.

Soon will be build with usb network adapters support enabled (requested by romanxdream from 4pda).
P.S. I'm not adding everything requested to kernel. But this was only config modification.

I don't check xda often, so there can be a huge delay in my responses.

[DEV][WIP] brcmfmac wifi driver & qcwcn libs for MSM8974-based devices like Sony Shinano

The intention behind this thread is to share some experience of a little project where I try to migrate the Sony Xperia Shinano devices (based on Qualcomm MSM8974 chipset with a Broadcom BCM4339 wifi/bluetooth chip) from the old bcmdhd wifi driver to a close-to-mainline brcmfmac driver. I want to share the progress and status here, and maybe get some hints. It is work in progress, and for sure it still contains some mistakes - I haven't done something like this before and am still learning.
Why?
The Shinano devices are still maintained by the LineageOS, and some devices are currently on the official LineageOS 17.1 stream.
The kernel however is terribly outdated, based on msm-3.4
There are some wifi issues with all LineageOS-based ROMs since years, like weak 5GHz connections and non-working wifi in some countries. There are some hacks around that, but they work (afaik) by practically disabling the kernel-level regulatory system by e.g. setting a static country code like "DE".
I am curious if we can improve that by updating the kernel drivers and network/wifi components, and maybe also the firmware (to the latest release available from Broadcom, 6.37.34.43 ?) . I got the ideas from Sonyxperiadev/Loire (+ related platform config), the Linux Backport Project and other MSM8974 based devices.
Working so far:
Did a few tests only so far, STA with WPA2 and p2p (hotspot) seem to work
Wifi connection is stable on 2,4GHz on 00 world regulatory domain (tested on a Z3 and a Z3c)
5GHz manually setting a country code (could only test DE)
Switching countries / setting new regulatory domains is now working, too
Download speed looks OK to me, in my case at least better than before Download >60MBit, Upload >30 Mbit on some initial tests.
Not working yet:
WifiHAL (qcom-caf) does not work correctly. This may create multiple issues, tbd.
Connection bandwidth seems to be not reported correctly
I don't know if wowlan works (interrupts working?)
Stability: After 1-2 days without reboot wifi sometimes crashes but immediately reconnects. Reason not yet understood.
Patches & Picks
Kernel:
backported and configured brcmfmac, cfg800211 wireless configuration API and wireless network stack from linux-stable v5.8 by adopting the compatibility patches from the linux backporting project.
updated Shinano device tree, updated Z3, Z3c and Z2 (Z2 test needed!) defconfigs (unset bcmdhd and enabled brcmfmac) and removed board-sony_shinano-wifi.o in the arch-msm makefile
Note: the backported drivers and compatibility-patches are located in a separate backports/ subdirectory
Sorry, this is work in progress and contains some hacks, to be cleaned up later
--> https://github.com/LineageOS/androi...1...Tom1000:lineage-17.1-driver-backport-v5.8
Vendor blobs / device z3(c): removed proprietary firmware and replaced that by publicly available firmware for bcm4339 on linux-firmware.git
z3c --> https://github.com/LineageOS/androi.../lineage-17.1...Tom1000:lineage-17.1-brcmfmac
z3 --> https://github.com/LineageOS/androi.../lineage-17.1...Tom1000:lineage-17.1-brcmfmac
Shinano-common: Use qcwcn instead of bcmdhd WLAN device, serve wpa_supplicant_overlay.conf
--> https://github.com/LineageOS/androi.../lineage-17.1...Tom1000:lineage-17.1-brcmfmac
msm8974-common: raise wpa_supplicant version (unknown if we need that) and update sysfs node for MAC address
--> https://github.com/LineageOS/androi.../lineage-17.1...Tom1000:lineage-17.1-brcmfmac

As a follow up, the driver seems to work quite stable already. I still have issues with nl80211 private commands, as a mainline brcmfmac does not seem to accept command strings passed via a libnl control socket like this:
qcwcn/wpa_supplicant_8_lib/driver_cmd_nl80211.c
@vknecht : I've seen your backporting work for the Xperia X. How does this work for Loire with SODP? Does e.g. a "set country code request" work for you, and if so, can you give me a hint?

I need some feedback from people with a Z3/Z3c/Z3Dual to see if the new builds work in affected countries, where 5GHz wifi is not working on current custom ROMs like e.g. LineageOS 17.1. I would appreciate if you test one of the builds below and send me a full log.
WARNING: The following builds are for debugging purpose only. Do not use them as a daily driver, as they have SELinux disabled and create excessive log entries. This ROM is not stable, some features are not yet implemented.
Xperia Z3 (D6603):
lineage-17.1-20201227-UNOFFICIAL-z3.zip
drive.google.com
Xperia Z3c (D5803):
lineage-17.1-20201227-UNOFFICIAL-z3c.zip
drive.google.com
Xperia Z3Dual (D6633) Update 10Jan2021:
lineage-17.1-20210110-UNOFFICIAL-z3dual.zip
drive.google.com
Z3Dual build has SELinux enabled already
If possible, please follow these steps:
Install ROM with TWRP for Android 10 or Lineage Recovery for 17.1
If possible, factory reset the device. Be sure to get rid of all former Magisk modules which try to set country codes etc. (if applicable).
Make sure a a local SIM card is inserted.
Boot the device. Enable mobile data and enable wifi. Connect to a 5GHz capable access point or router.
Optional: Increase log buffer size. This may be required as the kernel is set to verbose logging, creating large logfiles. You can do this via settings/developer options or via adb:
adb logcat -G 8M
Get close to the access point or router, so that the device would prefer 5GHz over 2.4GHz.
Reboot the device and let wifi connect. Check if device uses a 5Ghz connection. (Ignore bandwith / speed for now.)
Create a logfile, e.g. with this command via adb:
adb shell logcat -d -b all > mylog.log
The logfile may contain private information, so I recommend not to post them public. Together with the ligfile I would like to know
a) Wifi 5GHz working?
b) The country in which you have tested this.

nice work bro.
i live in iran and in this build my Z3 Dual detects wifi networks while the sim card is also connected.
but in 10 Jan 2021 update my phone can't detect my router's wifi unfortunately while the previous build could do it without problems.
hotspot turns on on both 2.4GHz and 5GHz.
in this new build cellular network and data are working.

Thanks @TheShadowOfAGhost20 !
Can you please run a root shell (E.g. by connecting via ADB, run adb root, then adb shell) and then
$> iw wlan0 scan → scan for networks
and then look if your access point is found?
Furthermore, can you please check which WiFi channel this particular router ist set to, and if possible the bandwidth?

hi mr.tom. it's perfect as always, found no bug except wifi signal power, it's weak compared to stock roms but there was no difference in speeds. maybe it's because of wifi icon that shows little weaker signal.
and about overheating: i didn't test this build for long but while working with it i have noticed that my device is cooler than previous builds, maybe it's because of this new kernel.
i have recorded 4k for about 7 minutes then my phone rebooted i think that was because of too much heat, then i've reinstalled stock rom, however, stock rom's camera won't let me record much and the app shuts down because of heat, so i can't find out if stock rom can record 4k at least without rebooting.
i need to test this build for more time i hope the heating is now gone
and one question: can you port cyberian camera mod for these roms? or is that possible?

lineage os recoveries have these problems yet, there's no fix for that, only the developer can fix it. currently the twrp works if you flash it to FOTAKernel partition but i think the twrp is useless because it doesn't install these builds.

Surely better to do: fastboot boot recovery-20201012-TESTING-z3dual.img rather than a "flash" recovery. What would be the point in flashing a recovery if its not working.

Hey
Thanks @Mr.Tom_Tom for new build and @TheShadowOfAGhost20 for testing dev builds!
today i installed the new release
but i have some problems with recovery and boot
after installing Lineage i cannot boot to recovery again
i tried adb, android advanced boot options and "fastboot boot image.img"
none of them taken me to recovery mode
so i needed to install Magisk , OpenGApps , and rom itself with adb sideload and reboot to system because i can't boot to recovery again
i'm now installing my apps for daily usage testing - i need about one or two week to test and use and see if anything is wrong or not
for now WiFi problem is gone , i have full wifi access and both sims antenna
again , thanks to everyone puts effort on this project (and sorry for bad English)
i will update this post if i found anything

If your going to settings\system\developer options\advanced restart\power\restart recovery , Forget it! this method doesn't work for now, & will only boot you back into Lineage. It's an issue that hopefully get's fixed in the future.
But here's a better way of entering recovery without having to flash it...
Check all your drivers are installed correctly & make sure you have the correct recovery to hand.
Here's what I Command:
adb devices
adb reboot bootloader
fastboot devices
fastboot boot recovery-20201012-TESTING-z3dual.img
Good luck!

Hey again
Thanks to @netwave i can now boot to recovery without problems by going to fastboot from adb , and booting image directly by "fastboot boot"
while using devices after installing new release , i have a problem with WiFi connectivity
when i lock the screen by power button , the wifi disconnects
for example i use whatsapp a lot and when screen is locked wifi is not connected
i checked power settings - and even set the battery profile to "Quick" (and battery saver is off) but it did not help
is this a bug or a feature?

Have you tried without Magisk installed? Don't use v22.0 what ever you do as it disables WiFi

Ow
I'm using Magisk and it is version 22.0
and even root not works
should i reflash ?
Edit : Ok i'm flashing again now

Install the Magisk uninstall.zip from recovery
when your back in Lineage your still have a disabled WiFi as Magisk does not uninstall correctly.
So Install the original boot extracted from the Lineage.zip to get things working again.
- adb devices
- adb reboot bootloader
- fastboot devices
- fastboot flash boot boot.img
- fastboot reboot
Then your be sorted.
