Debian Lenny now running on Hero! (see post 9!)

Has anyone managed to get Debian running on the Hero (as per the instructions in the Dream forum?)
P

I tried but I'm stuck because ext2.ko needs to be compiled for the Hero (managed to boot debian IN recovery mode with the custom image but not under the stock hero cupcake) and I haven't really had the time to look how to do that.
Also, I had hard time installing debian because of weird sh behaviour (looks like it's also cupcake's fault) and needed to modify the install script so it uses busybox tools.

I was getting a fail on the 'modprobe ext2', because of the lack of kernel modules.
Chmod 4755 on the sdcard also fails because of the way it's mounted, you need to run the installer from somewhere else instead.
P

su <installer.sh does work, but sometimes chmod just says "Operation not permitted" and mount fails when using the stock utils on my phone, using busybox seems ok, and I belive that I'm rooted correctly, so I don't know why some chmod fail.
Can ext2.ko be compiled alone or does someone need to rebuild a brand new kernel for the hero ?

ext2, ext3 & other are compiled into the current hero kernel.
Have you tried to compile a kernel from the magic 32a sources that htc released? maybe it boots on hero too (i'll try today, if i have time)?

What does modprobe actually do?
I guess it's important, because when I try and start debian, it all dies horribly and reboots the device.
Not had time or inclination to really investigate yet!
P

modprobe is a wrapper that calls insmod and rmmod(-r option).

modprobe loads a kernel module into the kernel using insmod
In this case, ext2 seems to be needed in order to mount debian.img (looks like it fails there, even if ext2 is compiled into the kernel). No idea about what makes mount fail, but I know that it works in recovery and doesn't in android
If you want to reseach a little about debian on the Hero, I suggest stripping out the reboot line in bootdeb, you will save a lot of time.
No, I didn't try to compile anything for the Hero personally, basically beacuse I have no clue about how to do so (yet)

OK so the normal mount command won't mount debian.img, but 'busybox mount' will.
Woohoo, success!
My doing 'rm /system/bin/mount' this makes 'bootdeb' use the busybox mount instead, and hey presto!

Here is my installer.sh btw... I copied the debian.img to /sdcard/debian/debian.img but everything else to a new directory called /data/debian. This allows chmod 4755 on the installer.sh file.
I used the 2.1 zip from here.

suid for all /system/bin/ ????

That's from the standard provided installer.sh script.
I don't see any issue or danger with that tho? If you prefer you could do just do the files individually.
P

well... with
Code:
cd /system/bin/
chmod 4777 *
every executable on /system/bin will be executed with the permissions of the executable's owner, and everyone have rwx access to every single binary in /system/bin

What exactly can you do with Debian?

You sohuld be able to do anything on your phone you can do with a full debian distro.
Shame there's no hero with a hardware keyboard tho!

Yeah I figured that out lol, but what can you do with a debian distro?

Still fails here, no idea about what to do.
# busybox mount -o loop,noatime /sdcard/debian/debian.img /data/local/mnt
mount: mounting /sdcard/debian/debian.img on /data/local/mnt failed: No such file or directory
/sdcard/debian/debian.img and /data/local/mnt both exist, and this line works in recovery
Any idea ?
EDIT : Fixed it !
In bootdeb, I needed to replace "mknod /dev/loop2 b 7 0" with "mknod /dev/loop0 b 7 0"
Maybe I'll rebuild a debian zip ready for the hero with a proper install script, or even as an update.zip when I'll look into android customisation
BTW (offtopic) : I'm also really intrested in a stock android (like Cyanogen roms for the G1) with mods for the Hero (with Flac patches for example), and maybe donut ! I'll be glad to help if you need.
EDIT 2 : Also, I don't really like how the script is done. In a world of android multitasting, we only can run one debian shell at the time ?
My idea is easy to do (I think) :
- Don't make bootdeb run chroot directly
- Make a debshell script that will launch a debian shell
- Make a debshutdown script that shuts down debian and doesn't reboot the phone if you throw it arguments.
OR : Make a big debian script that parses the command line and do what the 3 different scripts do, and do like the classic bootdeb if no argument is providen
I hope I explained what I think well

I DIDN'T need to do that, how weird!
P

Why Debian?
Why would we wan't to run Debian(=linux) when we have android(=linux)??
I'm also a bit worried about the permissions in /system/bin.. This means that everyone can make changes to every binary that Android has..
Virusses are not yet in the open, but you really make it very easy to exploit your phone (imagine a virus which acts as a dialer!!)

[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?

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.

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

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.

[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

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

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?

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...

I have no problem with the external SD card.
The problem I'm having is with internal storage, this is a little demonstration how it looks like :
When I open an app for example : Explorer, It shows me this:

When I go to the parent folder, it will become like this :

as the user above stated it might be a permission problem but i dont believe that is the case because /emulated/0 is the internal storage...
can you please name one app so i can check it? i am running v20d and not rooted but i dont think one letter can make the difference lol and if you can not get access with root than i dont think that it matters.
eidt: just saw you new comment i am downloading es explorer to try and look at the problem
---------- Post added at 10:56 AM ---------- Previous post was at 10:03 AM ----------
ok so i looked into it and it seems to be an android problem
it seems like some why the user t=does not have read permission
since i dont have root i can not fix it but you can (because you have root) i am guiding you blindly with out testing it...but i am sure it will not do any harm if you follow it.
first little guide so you have some kind of knowledge about what you are about to do if you dont already have.
ls - see the content of a folder
cd - enter in to a folder ( or out by ".." )
chmod - change permissions
su - use another user
for the steps:
1. download terminal emulator.
2. cd storage
3. cd emulated
4.(its a small L not a capital i) ls (just to make you sure you have the same error as me)
5. cd ..
6.(its a small L not a capital i) ls -la (just to make sure you see the permissions as me to the emulated folder(the letter on the side))
7. su root
8. chmod -R 775 emulated
and i believe your are done let me know if it worked

1. download terminal emulator.
2. cd storage
3. cd emulated
4.(its a small L not a capital i) ls (just to make you sure you have the same error as me)
5. cd ..
6.(its a small L not a capital i) ls -la (just to make sure you see the permissions as me to the emulated folder(the letter on the side))
7. su root
8. chmod -R 775 emulated

Thank you very much,
This is what I did :
Nothing happened.

It doesn't want to change permission.

2 things:
1. you forgot "su root"
2.
you wrote "chmod -R775 emulated"
instead of "chmod -R 775 emulated" between the R and the 775 there is space

did it worked?...
there is no error....
do "ls" after "cd emulated" to check it if you dont get permission denied that means it worked

No, it didn't work :

:-/ can you do ls -la after cd storage and upload the pic?
and you can try and do cd storage > su root > chmod 775 emulated > cd emulated > chmod 775 0 > chmod -R 775 0 > ls-la (the last is for checking) if it does not work
you can try one last thing reenter terminal than su root > cd mnt > cd user > chmod 775 0 > chmod -R 775 0 > cd 0 > ls-la and if this does not work i am out of ideas...i dont know maybe google did it in purpose somewhy.
in the end it is not such a big problem because you can still see the content of it you just cant just go back to it when browsing in any app which is not big deal because you can always reopen the app.
maybe some one else can help you

It is a big deal to me, because I'm not able to select a folder in internal storage as a virtual podcast, because the podcast app can't enter 0.

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
