[KERNEL/TUTORIAL] UPDATE 31/07 Howto mod the stock XXJVR/S/T kernel SU/Init.d Support

Well what do you do when you're bored and need some distraction .....Modify the stock kernel and include SU!
If you just search on the internet and especially on XDA than you find out that this is not so difficult.
The only purpose of this modified kernel is install SU and thus get ROOT
Why superuser and busybox are not installed by default is simple: it takes only 1 minute to download it from the market...
So here I give you the stock kernel + su/Root for XXJVQ/ XXJVR
installation:
1. Flash the tar file with Odin
2. Download superuser from the market and install it
3. Download Busybox installer from the market and install it
Credits to Supercurio, Hardcore, Liliniser for the tools and sources
Tutorial is Linux based!!!
So if i can do it than you can do it also!! All you have to do is read and follow post 2
Update 01/08/11 Added XXJVT
Update 01/08/11 Added Working XXJVR
Update 06/07/11 Howto add init.d support to the kernel (post 3)

Tutorial
1. Download and install the needed tools
2. extract de stock kernel to a temporary directory
3. modify the init.rc script to include your su install script.
4. add in the tmp folder busybox and su
5. add in the sbin directory your install script.
6. Recompile the kernel
7. Tar de kernel
8. Flash the kernel with heimdall or Odin
1. Download and install the needed tools
* Cross compiler: http://www.codesourcery.com/sgpp/li...eabi/arm-2009q3-67-arm-none-linux-gnueabi.bin and install it to /opt/toolchains/arm-2009q3/
* Kernel repacker made by Liliniser / dkcldark : Download from supercurio's github. with (if installed) git clone git://github.com/project-voodoo/kernel_repack_utils or goto the website https://github.com/project-voodoo/kernel_repack_utils and click on download.
* Download busybox,su and the install script from this post, and extract the files.
2. extract de stock kernel to a temporary directory
Copy the original zImage to de directory where you extracted the kernel repacker
Rename it to zImage.org
create a temp directory in the kernel repacker directory
Open a linux shell and go to kernel repacker directory
./extracter.sh -s zImage.org -d temp (hit enter)
3. modify the init.rc script to include your su install script.
Go to the temp directory and edit init.rc with your favourite editor and put this on a new line at the end off the file.
service install_su /sbin/install_su.sh
user root
oneshot
Save the file and exit
4. add in the tmp folder busybox and su
copy busybox and su to the tmp folder in your extracted kernel folder
make sure they are markt als executable.
5. add in the sbin directory your install script.
copy install_su.sh to the sbin folder in your extracted kernel folder
6. Recompile the kernel
Open a linux shell and go to kernel repacker directory
./repacker.sh -s zImage.org -d zImage -r temp -c gzip
congratulations you must cooked your first modified kernel
7. Tar de kernel
tar -H ustar -c zImage >code.tar
8. Flash the kernel with heimdall or Odin

Howto add init.d support to the stock kernel
Whell this is easy to implement
1. Open a linux shell and goto to the extracted kernel directory. (read post 2 howto do that)
add the following lines to the init.rc file
Code:
service initd_support /sbin/initd_support.sh
user root
oneshot
Save the file and exit
2. Create a new file in the sbin directory called initd_support.sh and add the following code
Code:
#!/tmp/busybox sh
if cd /system/etc/init.d >/dev/null 2>&1 ; then
for file in S* ; do
if ! ls "$file" >/dev/null 2>&1 ; then continue ; fi
/system/bin/sh "$file"
done
fi
Save the file and make it executable
3. repack the kernel (see post 2 for the howto)
4. on your device mount system Read/Writable and create the directory /system/etc/init.d
5. Copy your init scripts to /system/etc/init.d/
Make sure the name starts with a S, and set the permissions to 777
Example step 5/6
Code:
adb push Stweakscript /sdcard/
adb shell
su
/tmp/busybox mount -o remount,rw /system
/tmp/busybox mkdir /system/etc/init.d
/tmp/busybox cp /sdcard/Stweakscript /system/etc/init.d/Stweakscript
/tmp/busybox/chmod 777 /system/etc/init.d/Stweakscripts
7. flash the kernel

I'm sorry in advance.
But WTF?

If you only want to root your rom don't wait for devs to do it but do it your self

Yes, and for learning purposes. Thanks for the tips, I was sitting down to do this on another phone the other day actually... it's good to see your ideas, I was getting pretty frustrated with the limited Android init environment (the toolbox commands are so limited!).

Thanks for this nice tutorial.Worked great!

Great! Now we have good rooting kernel.
If I want root - I want root, not tweaks and other "shiny" things.
Cfroot breaks BT in some cases, Fuguroot breaks Kies connection.
Kernel which don't add Superuser.apk as a system application is the best choice - we don't have to delete other system files and there are updates of this app, so why should we have older version on /system and new on /data as an update?

Can I do "adb root" on this kernel ?

Sure Just install superuser and busybox from the market

Wooow! These are the sort of tutorials I miss here sooo much. It's a developer forum, but what we are getting here mainly are ready-products (roms, modded kernels). And why not to do it yourself. But sometimes googling for the information is not so easy, because applies to different conditions(devices, phone models, soft versions). There are many people who would spend their time learning how to compile a kernel or edit framework files. But there are so few tuts on this here... I miss tuts that tell how to do things step-by-step, without any specific linux/java knowledge.

Why doesn't XDA have more stuff like this?
Thanks OP!

Yes, I must thank you too.
Now I understand... Sorry for my initial confusion!

I've problem:
after applying script:
line 47: ./out/project/original.cpio -> no such files or directory
Any idea ?
Where is original.cpio files ?
Screen of error:
{
"lightbox_close": "Close",

tq man...!!

man this is amazing, I was looking for something simple like this for months. It's right, should be more posts like these in xda

+1
Thank you very much for this, lownoise
We need more topics like that, since I am interested to learn myself...
Members posting tutorials like that are always appreciated, I cannot thank you enough.
Do you know how to replace the recovery 3e with 2e additionally?
It would be great to know since I want to have it CWM compatible (flash unsigned update.zip)
AFAIK recovery is a part of the kernel....
It would be great if you could point me to the right direction.
Others probably would like to know that as well.
Thanks again.

Thanks.

[ADDON][Xperia S] Generic startup/init.d scripts support for Stock ROM/Kernel

[ info ]
i am attaching a easy to run package which contains the files required for full functionality of executing startup scripts (init.d scripts)...
basically this will allow the user to execute custom shell scripts, placed in /system/etc/init.d/ folder and they will be executed on each boot!
i dont have this device yet!!
thanks to Jozinek for testing this on his phone!
[ requirements ]
stock rooted ROM
windows PC with adb drivers installed
[ how to install ]
download the provided zip package
save it on c:\
extract the contents of the package
connect phone with usb debugging active to PC via ADB
execute "runme.bat"
follow onscreen instructions & enjoy!
incase some issue is there post the output/log of script
[ additional info ]
i have added the following things in the package:
corrected /system/bin/sysint file
run-parts binary in /system/xbin/run-parts (which is basically busybox 1.19.3 binary)
correct /system/etc/install-recovery.sh file (this file gets executed by default on stock kernel too!)
test/example script /system/etc/init.d/99test
to check if this is working the test script (99test) will create a temporary file /data/local/tmp/init.d_log_test.txt on each boot
[ donations/device fund ]
i dont yet have this device but i plan to buy it.... if u guys want to donate to me to get this device OR if u feel that this work has helped u OR u think that the work i put into making this is worthy of donations, then click on the following link for buying me some coffee/beer/etc

Nice work, this will enable the Speedy v7 int.d hacks, can you incorporate this in the above? As an addon perhaps.
Done, $50 "AU" dollars coming your way mate.

this init.d support can be used to execute ANY shell script/program at startup... u are free to choose the ones u want...
if anyone needs help on how to push the scripts onto device let me know... but script specific info i dont have, u will need to ask the developer of those scripts..

I used this script to move dalvik cache to /cache folder:
Code:
#!/system/bin/sh
#
# relocate dalvik-cache to /cache/dalvik-cache
if [ ! -d /cache/dalvik-cache ]
then
busybox rm -rf /cache/dalvik-cache /data/dalvik-cache
mkdir /cache/dalvik-cache /data/dalvik-cache
fi
busybox chown 1000:1000 /cache/dalvik-cache
busybox chmod 0771 /cache/dalvik-cache
# create symlink
busybox mount -o bind /cache/dalvik-cache /data/dalvik-cache
busybox chown 1000:1000 /data/dalvik-cache
busybox chmod 0771 /data/dalvik-cache
After reboot i saw folder /cache-dalvid in both folders /data and /cache, is it normal?
Thank!

I found that for devices rooted with locked bootloader
Line 21 of runme.bat need to change from
HTML:
@files\adb shell "su -c 'busybox mount -t ext4 -o rw,remount /system /system'"
to
HTML:
@files\adb shell "su -c 'busybox mount -o remount,rw /system'"

This is all great, exactly what I was looking for! But what about if the ROM already has a custom kernel that makes use of /etc/init.d? Do the /etc/init.d scripts get executed twice?
EDIT: in my phone this solution can't work. In the init.rc file the following lines are commented out
Code:
#service flash_recovery /system/etc/install-recovery.sh
# oneshot

Thanks, it's working but I have a question, how we can include this in a rom?
Please respond, I would appreciate that

That means I don't need run-parts if I've busybox installed?

1-Tell me please if I understand: I've done everything the post says Doomlord ([ADDON] [Xperia S] Generic startup /init.d scripts support for Stock ROM / Kernel) my question is this, after this I can already install scripts from cwm?
2-I try installing ''NullVoid'' tweaK by cmw and apparently well was installed. (I say apparently because i do not know if it is working)
3-Another thing about Tweaks: These have to be installed every time the phone restarts? This tweaks are compatible with the stock ics rom? (With the Doomloard Method ?

So the "install-recovery.sh" file is executed by system by default and does not need to be executed manually from terminal or what else?
And about the file...that is not a one-run file...right? It is executed at every phone boot...right??
Thank you.

Hello,
Is this package valid for deodexed rom?
I'm on stock .55, bootloader locked.
Currently the folder /system/etc/init.d doesn't exists
Thank you

it doesnt matter which ROM you are on... this should work on any ROM as long as the kernel ramdisk executes install-recovery.sh service...
dont worry it creates all required folders/files

If you have TWRP in your Kernel then it wont be replaced, as this is not kernel based. For that you need to flash stock kernel then use this mod. you will get Dual recovery.

How it works:
1. Each boot.img packs zImage (real kernel) and ramdisk (special files for kernel use)
2. This one has all modifications from LGGW rootboot by Justin Case:
a. Adds su binary, superuser.sh install script, modified install-recovery.sh and additional step into init.rc file to invoke superuser.sh install script. Also modifications to mount system as rw and some disabled security.
3. So basically it mount system as rw and does following (cut from superuser.sh install script):
Code:
#!/system/bin/sh
/system/bin/mount -o remount,rw /system
/system/bin/sleep 2
/system/bin/cat /sbin/su > /system/xbin/su
/system/bin/cat /sbin/su > /system/xbin/daemonsu
/system/bin/cat /sbin/install-recovery.sh > /system/etc/install-recovery.sh
/system/bin/chown 0.0 /system/xbin/su
/system/bin/chown 0.0 /system/xbin/daemonsu
/system/bin/chown 0.0 /system/etc/install-recovery.sh
/system/bin/chmod 06755 /system/xbin/su
/system/bin/chmod 06755 /system/xbin/daemonsu
/system/bin/chmod 755 /system/etc/install-recovery.sh
/system/bin/sync
/system/bin/sleep 3
/system/bin/reboot

I have dumped the rom from my debug/test version and was wondering if you were able to give me a guide on how i could try and flash it with a retail version? I presume this root guide probably won't work for me

Well, if hardware and partitions are the same - I do not see why it will not work. However, it will not help to flash.
I might try to compile twrp, but will have to carefully read its docs first.

thanks @XorZone confirmed as working and a nice easy process too (I was already unlocked).
Out of curiosity, modded LGGW rootboot or just renamed?

Thanks for letting me know!
I reverse engineered changes in LGGW by unpacking and comparing ramdisks from both rootboot and original lg kernel and then applied the same changes to our kernel extracted from PC Companion files.

great thinking and good job ?
btw, that pic confirmed su access to watch over bluetooth debug connection ?

really great tutorial. I am planning to buy this watch, but I think currently there is NO app that requires Root. so I wonder how can we get benefit of this ?

There is at least Wear Control app: https://play.google.com/store/apps/details?id=octathorp.wearcontrol
I plan to code density changer that will require access to adb, so either from rooted phone or rooted wear.

that's awesome man! will purchase mine next week, can't wait to root it. thanks for the answer.

Thanks for the root, XorZone. For anyone wondering, here's the dmesg of the watch
A few small observations from digging:
The main chipset seems to be the BCM23550
The CPU has 4 cores, 2 are disabled in software. Should be easy enough to reenable if you please
It definitely has WiFi hardware, but the firmware is currently missing from the image. If you mange to get a hold of compatible firmware and nvram, it should be simple enough to get WiFi up and running
The WiFi firmware message mentions a "43341". Which is odd because apparently the main chipset does have WiFi support built in. Searching for a Broadcom 43341 gives you this, but this might just be a red herring.

Yeah, I noticed the same about WiFi chip, it might be that they packed bcm43341 as part of the BCM23550 soc, like Invensense MPU9250 chip packs mpu6500 inside.
For the 43341 I'm finding it in the configs here: https://android.googlesource.com/kernel/tegra/+/bdde9f16131a5ac2039062d5ce22e3e153acbe68^!/
Looks like BCM43341 is BCM4334 + NFC chip, so we could try S3 I9300 files as per http://redmine.replicant.us/projects/replicant/wiki/GalaxyS3I9300Firmwares

I can not get my device to show up in adb devices and its driving me crazy. Tried windows 7/8/server 2012R2 ..lol
Now I have done my fair share of custom roms and bootloaders.
OG Droid
Nexus
Nexus 10
Asus Memo Pad (came from alarm company, and could only load one app...now its a full running tablet)
I am sure its a silly thing I have done or am missing...
Thoughts....ideas?..need more info?

As usual, check if adb enabled in settings-about-developer options, if there are no developer options - it is as usual 7 times click on build number in about screen.

And please use Q&A thread for such questions

Hello Guys/Girls/Non-Binary this should just be some Tutorial because I didn't find a lot about this on xda.
I have Twrp installed check out this thread on how to do it: TWRP FOR S20 FE EXYNOS
TWRP KEY COMBO: Power + VolUP
I will give you the download-link of the right version of the Twrp if you have the SM-G780G because i feel no one has it and searching comments is kinda bothering.
Twrp for SM-G780G (dunno if it works on others but should) is in attached Files on This Post.
This Version of Twrp has a small "bug" or a kinda non see able feature because it doesn't give you a GUI thing for enable Write-Rights in "/system_root" if you are a n00b don't worry explain later.
First of all you need adb and linux is kinda good because i don't know on how to do some zip things in Windows (and it kinda sucks anyway but don't cry )
So the real tutorial starts here (you HAVE TWRP and a boootable system right now) if not check the link i gave you.
First of all you root the phone (You can skip this step if you don't want root rights):
Download Magisk-Zip : Magisk Zip
Connect the Phone and your PC and put the magisk.zip on your phone. -> In Twrp go to install -> Click Magisk.zip.
Wait and some mad voodo magic from your Lord and Savior topjohnwu: https://forum.xda-developers.com/m/topjohnwu.4470081/
appears and you're rooted.
So this is the more complicated part of the tutorial (because we only have android 11 on this phone we need to kinda manually deodex you're services.jar I did a tutorial on that here:
Sig Spoofing on Android 11
You can use the exact same steps!!
short description: download haystack11-attempt, dexpatcher, the zip you need to rename, - pull and deodex your services.jar - flash the zip in Magisk!!
After that boot in system install fdroid (put the apk from your PC to the phone install via Samsung-files or some other app) download signature-spoof checker from fdroid and give the permission if that works youre good to go.
Go in Magisk -> Reboot to Recovery (Or Reboot in Twrp with Key-Combo)
Now we are debloating (the de-bloat in /system_root is necessary the pm uninstall commands and i will add them later forgot to write down and I'am always high(so i forgot them) also they are optional) for real you could de-bloat a lot more here but I doesn't wanna ruin camera app and things real Samsung boys will know what i talk about. but if you have better de-bloating options go and comment!
System_root de-bloat necessary:
adb shell

rm /system_root/system/priv-app/Velvet/Velvet.apk
In Twrp -> Mount System
Now open Terminal on Your PC (in use of ADB) and try to do one of the delete commands in /system_root if you're getting a rights error don't worry I explain how you get it working.
The command is:
mount -o rw,remount /system_root
Go try a delete command in /system_root again. everything should be fine now.
Go through all the de-bloat commands after that download the microG flash-able zip of your linking here: (Or use Nanolux)
https://github.com/FriendlyNeighborhoodShane/MinMicroG_releases/releases/tag/2021.04.28
Put it on your phone and flash it throuh twrp.
Boot and Boom OneUI 3.1 with MicroG and low bloat this Exynos now runs like a beast.
Sorry this my second post on this thread so don't kill me for my bad English or some dumb mistakes!
Credits to all the beautiful guys on xda! This stuff would never happen without those Legends!!

Exynos is SM-G780F any owners of the G i.e. the snapdragon 4G version following your link will have a bad time.

You can't pass safetnet with microg installed, it has been an issue for a while
SafetyNet API · Issue #181 · microg/GmsCore
As of version 0.37 Pokemon Go uses GMS's safetynet feature and I for one can't get past login. What is the implementation status on safetynet, is this out of scope for microg?
github.com
If you want to pass safetynet you'll have to remove microg and reinstall google play services to able to pass it.

Hello, does this microG degoogle work with the S 20 FE Snapdragon
