I've been working on getting Ubuntu running on my Sprint Galaxy S3 using the same method I used on my Epic 4G - kexec from recovery loading the root filesystem off a partition on an SD card.
What I've done so far:
* Found a kexec loader to boot into a custom kernel, which is required for booting off an SD card, among other things;
* Compiled a custom kernel with KGSL DRM support enabled for Freedreno;
* Built a minimal Ubuntu 13.10 armhf rootfs and compiled the Freedreno DRM/DDX/Mesa Gallium driver with changes to support the Adreno 225 and stub occlusion query (possibility of full dekstop OpenGL 2.1 support!);
* Got X11 working with USB keyboard, touchscreen, and fbdev. Still working on getting the Freedreno DDX to load.
I still get a kernel oops with the camera driver (http://pastebin.com/egZbxsED), but it apparently doesn't affect stability or cause reboots anymore.
Working so far:
* USB Host - only tested with a keyboard, but other input/storage/audio/video devices should also work.
* Framebuffer console - thanks castrwilliam!
* Touchscreen works with X.org fbdev driver and the following added to /usr/share/X11/xorg.conf.d/11-evdev-quirks.conf:
Code:
Section InputClass
Identifier "Touchscreen"
Driver "evdev"
MatchProduct "sec_touchscreen"
EndSection
* Power and volume buttons
Untested:
* Bluetooth - might need firmware
* Sensors - should work just fine
* Home, menu and back buttons should work but probably need mapping
Unlikely to work due to proprietary Android-only blobs:
* Camera
Kernel config changes:
# IMPORTANT: remove the line that says "depends on !MSM_KGSL_DRM" from drivers/gpu/msm/Kconfig:70
CONFIG_DEVTMPFS=y
CONFIG_DEVTMPFS_MOUNT=y
CONFIG_VT_CONSOLE=y
CONFIG_DRM=y
CONFIG_MSM_KGSL_DRM=y
I may eventually post a pre-built kernel, but if you don't know how to compile a kernel from source, this guide is not for you.
Likewise, if you don't know how to prepare an armhf Ubuntu root filesystem, this guide won't help much.
After building the kernel, copy arch/arm/boot/zImage to your SD card along with the attached zImage.zip (CWM-flashable kexec loader).
It might need modifications (META-INF/com/google/android/updater-script) depending on how you have your card set up.
UPDATE: Unfortunately, this phone hasn't been a good fit for me. I never got very far booting Ubuntu or Freedreno, so I decided to sell it.
For anyone still interested in this project, I believe castrwilliam has the required patches.
When I get my next Snapdragon device (either the new Nexus 7, a Nexus 4, a Galaxy S4, or another phone with Adreno 320 graphics), I will post the Mesa patches for occlusion query support. Sorry I wasn't more helpful with this device.
Added to favourites, I'll see what I can do with it over the weekend

Maybe taking a look at how Motorola worked Ubuntu, in a way, with Webtop that came on the Photon. The Photon has the integrated Ubuntu-based 'Webtop' application from Motorola. The Webtop application is launched when the phone is connnected to the external display through Laptop dock or HD multimedia dock. In Webtop mode, offering similar user interface of typical Ubuntu desktop, the phone can run several applications on external display such as Firefox web browser, SNS clients and 'mobile view' application enabling total access of the Photon and its screen. In September 2011, Motorola released the source code of Webtop application at SourceForge.
I know it's not an app you're trying to use but it may help in finding how to work some of the kinks you have. I hope that helps
Hi, I'm the person maintaining Ubuntu currently for HP Touchpad (http://forum.xda-developers.com/showthread.php?t=2225462) (which also uses an MSM SOC.) It's starting to show its age... I'm trying to get this to where you have it currently on a Verizon S3 / d2vzw (obviously, kexec'ing into a Verizon kernel instead.) Maybe we could collaborate?
Currently I have the KT747 kernel (kexec host support as well as guest) (compiled as a zImage. If you can provide me with access to the patches you have for freedreno and hopefully also an initramfs image (I'm going to mod the HPTP rootfs, so no need there)... I'd love it.
My only modifications to the kernel so far are the ones I mentioned in the OP and three of Rob Clark's Freedreno commits from the mako-kernel branch of kernel-msm on his GitHub - namely, "kgsl: drm: remove checking on 'active'", "video/msm: add true ARGB", and "kgsl: fix null ptr on cache flush".
At one point I had X11 working with freedreno displaying the GNOME background, but the screen blanked after 10 seconds and I couldn't recover from that. Unfortunately, after experimenting with different kernel config options, I lost that semi-working configuration and the GPU started to page fault, sometimes displaying a corrupted screen and sometimes rebooting before displaying anything.
Believe me, I've been working on this for weeks, and it's very frustrating that it doesn't even sort of work. My minimal modifications to Mesa to get it to recognize the Adreno 225 are highly unlikely to be the cause of the problems, and I highly doubt the differences between the 220 and 225 are to blame since it was working at one point. It's a one liner, figured out from from freedreno/mesa issue #2.
Castrwilliam, the initramfs is the least of your worries. I don't use one, since its only function is to display the Plymouth splash, which doesn't work anyway.

Yeah, I realized how you were doing this after looking at the kexec script. I was trying to boot from Android, not recovery, and was under the impression you had put a disk image on external SD, and then made the initramfs loop-mount that and boot from it... but now I see you partitioned it.
It's a shame you don't have your original config, I'll try to get it booting again on my end. I remember doing something like this a while back, where I made like 10 differently configured kernels at once, and tested them each in turn. I imagine the ramconsole would help a good bit so that I could look a how far we're getting. (The touchpad has its own version of that, which you can read directly from the bootloader (bootie.) Then again, it also has LVM volumes for storage instead of actual partitions (except for boot) - which makes it uber easy to boot lots of OSes.)
Currently I'm not doing too well. I remember that kexec did work at one point on d2vzw hardware but I'm assuming that it still does now (new bootloaders, 3.4 kernels, ...) I do kexec -e, the reboot happens, I see the Samsung bootloader screen, then the screen blanks for like 5 seconds and it reboots again - back into android.

The RAM console should be enabled by default, so check /proc/last_kmsg once Android boots back up.
It could be something simple like the root filesystem not mounting, either due to how you partitioned the card or not having time to settle, hence rootwait. Or it could be something else. I haven't gotten any useful output in /proc/last_kmsg with the framebuffer console enabled, so make sure that's disabled unless you want a headache and a psychiatrist visit.
Unfortunately, I've spent way too much energy trying to debug the GPU page fault, and I probably won't have much time to work on it after next month. I want this bug dead and forgotten, so more eyes would be great!
X11 works (shows something on screen) with the X.org "fbdev" driver. I can't reproduce anything with "freedreno" (or "modesetting", which I accidentally loaded at one point...)
The touch screen doesn't respond, but the power key works and brings up a shutdown dialog.
Screenshot attached. I used the 13.04 Touchpad rootfs with some modifications...
Okay, you can get the fbcon working by either loading it as a module during boot OR changing its "module_init" macro in drivers/video/console/fbcon.c to "late_initcall".
Picture attached. Sorry for blurriness, I don't have an actual digital camera, only what's on my sig. This should make debugging a bit easier.
Nice to see some more freedreno development on android phones
I'm using freedreno with a slightly different approach, starting it directly from android on a chrooted shell, which is a lot more easier to debug.
The kernel needs some fixes from the mako branch and the following configs:
Code:
CONFIG_DEVTMPFS=y
CONFIG_VT=y
CONFIG_DRM=y
CONFIG_MSM_KGSL_2D=y
CONFIG_MSM_KGSL_DRM=y
Rob Clark (the maintainer of freedreno) has been working on his own kernel driver for adreno gpu:
https://github.com/freedreno/kernel-msm/commits/ifc6410-drm
This would be a nice addition/replacement for the current qualcomm gpu driver.

HEY, look what I did?!
(There are a lot of patches req'd to get this far. Even at this point, there's a weird bug where the cursor loops across the edge of the screen and windows overlap themselves. If you want to know, I'll elaborate in a further post, otherwise, let's get that touchscreen working for release!)
Thanks to Rob Clark (again, the author of freedreno) who helped me get this far on his IRC channel at Freenode.

Are we keeping track of all the necessary patches? I'm on https://github.com/CyanogenMod/android_kernel_samsung_d2, branch cm-10.2_kgsl, with the per-process pagetable hack, the "active" kgsl_drm fix, Adreno 225 case in Mesa (freedreno_screen.c), and my stub occlusion query hack. I wasn't on #freedreno when Rob Clark pointed out the libdrm bug I heard about from the Wiki - did you fix that? I'm still getting the assert crashes.
I'll be on #freedreno at some point tomorrow.

I got this to work by using a fairly old libdrm, but a new DDX (xf86-video-freedreno). I haven't fixed the assert bug on the newer ones.
You need to patch the DDX's msm-device.c to set the width to 736 (has to be a multiple of 32), and then disable/comment out/delete where it calls the mode-set function (there's a comment about making xrandr happy in the right place.) I can make a patch soon, but I have a feeling that this is what made the other bug happen with the looping cursor.
edit -- I fixed the looping cursor. A patch is attached...
Youtube video of it working: http://www.youtube.com/watch?v=rh9wmmYuKxY
Tips:
Set the firnware path for the dhd (wi-fi) driver to /system/etc/wifi/bcmdhd_sta.bin (WITHOUT the _b2 buffix, it will be added by the module). Set the nvram file to /system/etc/wifi/nvram_net.txt. Then, add the Android partitions to the /etc/fstab (mmcblk0p14 is system.)
apt-get install xserver-xorg-input-multitouch and then add a config file under /usr/share/X11/xorg.conf.d/ to get the touchscreen working. It will act like a laptop trackpad. You MUST use the multitouch driver. "evdev" will segfault the server on any touch. Note that you can match the TS in an InputClass with its udev name, "sec_touchscreen".
The date that I compiled the working Freedreno libdrm was the date that Ubuntu 13.04 was released. I'm working on narrowing it down to a Git SHA1 revision. I used Rob Clark's repository, not the freedesktop one.
Use the master branch of the DDX, sorry for the earlier confusion.
For battery savings, you might want to cherry pick the DPMS commit from the a3xx branch of the DDX.

There are two binaries you can execute with adb shell stop/start that kills and restart the android proccesses, allowing access to the framebuffer.
Okay, so 2-D does work with my mods, but I just tried 3-D last night (ran es2gears with the Adreno 225 mod in place on mesa) and the pagefaults returned.
I did notice something about your pagefault reboots, though: they shouldn't necessarily be happening, it's a NULL pointer dereference that can be fixed in the handler by doing this in drivers/gpu/msm/kgsl_iommu.c (function is kgsl_iommu_fault_handler):
Change
Code:
curr_context->pagefault = 1;
curr_context->pagefault_ts = curr_global_ts;
To:
Code:
if (curr_context) {
curr_context->pagefault = 1;
curr_context->pagefault_ts = curr_global_ts;
}
So anyone got any updates for this if not i will start building upon what is there if it is ok

No longer developing for this phone

fhd kernel ( ZE551 ) & POSSIBLY hd (ZE550) with KVM & Bridge compiled. *need help*
MODERATOR NOTICE:
All thread posted in the Development section must have a link to kernel sources to meet GPLv2 requirements. Because this thread does not have proper sources linked and because development has stopped, the thread has been closed.
This is my first time working with Android kernels, but I compiled the 2.12.40 kernel source adding in support for KVM ( Kernel supported Virtual Machines, ie running Windows almost full speed ) and Bridge ( to allow qemu-kvm to set up network adapters bridged with the current wifi adapter ).
I tar'd the bzImage & modules, but don't know what to do to make something installable/flashable so will need help on that end of things.
Edit:
I uploaded a new flashable kernel img based off 2.19. This one should support: kvm, bridge and NTFS read/ *LIMITED* write, swap and ignore kernel module signatures. XDA only allows 8mb for .img files, so I tar'd it.
Edit2:
I compiled a ZE550 kernel ( called hd ) and if some brave souls want to try it, I also put together a boot.img.
Edit3:
New fhd kernel has been compiled with additional usb modules. Kernel should now load kvm related modules automatically, so you shouldn't need to use the script anymore.
Anyone brave/crazy enough to try it out? I'm guessing you need an unlocked bootloader & root.
Edit 4:
New fhd & hd kernels for 2.20
Edit 5:
New exfat.ko module

Why 2.12? 2.18 kernel source is available...
That just happened to be the kernel source linked in Android development. If this test works out, I can probably do the same thing with whichever kernel source is available.
Our phones are pretty amazing to be able to compile their own kernels natively on the device.
Sent from my ASUS_Z00AD using XDA Free mobile app
Finally able to compile the 2.18 kernel.. it's a bit weird since it acted like it was missing some files. Untar'd the 2.18 kernel source over 2.12's kernel source and that allowed it compile.
Anyway, it's in the OP called fhd_kernel_20150629.tar and should have KVM ( kernel supported virtualization ), Bridge ( for Qemu-KVM to create bridging ethernet adapters ) & NTFS Read/ *LIMITED* Write.
Once again, it's in the form of bzImage and the modules since I don't know how to replace the kernel on Android devices. ( normally, I'd just make a test linux line in the boot menu for Linux )
One suggestion would be to flash the zImage using
Code:
fastboot flash zImage nameofzImage
or test it using
Code:
fastboot boot nameofzImage
but I dont know if the phone supports the "boot" command.
I´m not sure about the modules either and I can´t test it, as my phone didn´t arrive yet.
Other solution, try this:

Can I ask how you included NTFS r/w support into your kernel? Did you just set the CONFIG_NTFS_FS flag?

I added CONFIG_NTFS_FS=m ( you could set to that y ) and CONFIG_NTFS_RW=y in /{working directory}/device/asus/moorefield/fhd/mofd_fhd_diffconfig
when you make the kernel, it's going to ***** about the config files not matching; follow the directions and manually update all of the other config files and it will finally compile.
Building for Android is a pita. )
Well, then here come the disappointing news (I discovered that when I wanted to include NTFS USB-OTG support directly by the kernel for my TWRP and it didn't mount it as R/W):
CONFIG_NTFS_RW is just a partial write support. It won't create files or folders, it can only overwrite existing files and only by the size they currently have
config NTFS_RW
bool "NTFS write support"
This enables the partial, but safe, write support in the NTFS driver. The only supported operation is overwriting existing files, without changing the file length. No file or directory creation, deletion or renaming is possible. Note only non-resident files can be written to so you may find that some very small files (<500 bytes or so) cannot be written to.

Only possibility available is to include ntfs-3g driver using fuse
Yeah, that is a bit of a downer. Now to figure out why nobody finished the NTFS kernel module.

Please keep me posted, I'd like to remove the dependency of ntfs-3g in recovery. I fear there actually is no native support of NTFS (googling was not helpful unfortunately)
1) modify module loading function to ignore module version/magic strings.
2) compile the kernel with toolchain used by ASUS (or close to it)
3) use pre-compiled tntfs.ko from original boot.img
I don't have right now the patch for module loading procedure. Need to check old Galaxy S3/S4 custom kernels source (but it's should be easy to patch by finding error string). In time when exFat module source wasn't available, this trick was very common in samsung custom kernels for exFat support.
Thanks
Wait wait wait. Did I read that correctly? Full speed windows? On the zenfone? I think I just died. Does this mean windows 8/10 or windows xp and below?
I know a bit about android kernel, and i'm thinking about buying this device. Well, i'm going to try to build a kernel for this device as soon as i got this device. One thing you should know is, android is an open-source, so before you uploading your compiled kernel, make sure you have already uploaded the sources

It's only in theory.
In reality, there is no Z35xx support in windows, and i doubt anyone will write drivers by himself (windows isn't opensource). Officially Z35xx is Android-only SoC.

To be honest? I can't remember since my main focus was getting kvm compiled in.
I've attached my .config for the 20150707 build ( in the boot image ).
I've also attached a screenshot of Windoze 7 being installed.
Commandline for Arch Linux x86_64 to start qemu-kvm to install windoze:
qemu-system-x86_64 -display none -vnc :1,password -monitor stdio -m 1G -smp 4 -enable-kvm -drive file=/mnt/0/machine1.img,format=raw -cpu host -cdrom /mnt/MicroSD/Vcd/en_windows_7.iso -boot menu=on --usbdevice tablet
breakdown of the command line:
-display none = no display, I did this to test the virtual machine. normally, you would probably use -display sdl w/ XServer-XSDL running
-vnc :1,password, This says to set up a vnc server with normal port + 1 ( 5901 ) and you expect a password to be set later
-m 1G, 1 gig of ram
-smp 4, our VM will use 4 cores
-enable-kvm, enable Kernel support Virtual Machines
-drive file=/mnt/0/machine1.img,format=raw, my "disk" file
-cpu host, use the same cpu information
-cdrom /mnt/MicroSD/Vcd/en_windows_7.iso, my Windows 7 install cd turned into an iso
-boot menu=on, enable the boot menu ( hit F12, etc.. )
--usbdevice tablet, Qemu's Vnc server sucks at tracking mouse positions so using tablet mode keeps the mouse pointer .. well on-point
Tks for share

Sup everyone,
I had this phone for 2 years before the wifi hardware died. It's rooted, twrp installed, everything works except wifi/bluetooth.
I don't use this phone for calls so no sim card no 3G or 4G that is.
So in the long search for alternate ways to get internet I came across several posts about using USB to ethernet adaptors, and that's what I've been trying to get for the past 3 days.
I have 2 USB to Ethernet adaptors Asix Ax88772C and Davicom DM9601 which I insert via a standard OTG adapter so they are not the ones that have the 5 pin USB (OTG like cable)
I've read that Asix is supported and built in G3 D855 kernel, OTG checker detects it but no internet whatsoever.
DM9601 is not supported by vanilla kernel so it's not detected (maybe because it's for Ax88772A and B not the C)
I have a kali linux and I installed all prerequisites to build kernel and modules so I tried compiling asix.ko usbnet.ko and dm9601.ko against various D855 kernels and tried several ready made D855 kernels too ..... everything ended up with errors when trying to insmod or modprobe the ko files
I really have tried everything to be tried and so my only hope is to flash a kernel with those modules built in namely usbnet asix and dm9601.
The kernel sources I'm using currently are the Navel-855 ones, and the kernel is also the latest Navel kernel.
Any help or guidance would be deeply appreciated

Obviously we all know this, but I'll say it anyway: I bear no responsibility for your device!
Background:
Initially I recompiled the kernel, but thanks to @fddm I was able to get this into a Magisk module. This is a take-off from https://forum.xda-developers.com/t/...-tether-lineageos-18-1.4295601/#post-86183959 Feel free to read that (minimal reading) for additional details.
What is this?
This Magisk mod adds the required iptables kernel module for TTL/Tether/unmetering for using your phone as a hotspot. I have Tmobile & with my plan, when I connect any device to the phone it is extremely throttled to around 0.5Mbps. With this mod and the settings below, you can get around that limitation. I go from 0.5Mbps=>80+Mbps with this mod. Root is required (look at above thread for details on that if needed).
Compatibility:
Confirmed OS's that work: LineageOS18.1, LineageOS19.1
ROMs: At this point I can't indicate what ROMs this will be compatible with, but it appears LineageOS18.1 works. I'm attaching that as well as a Android/AOSP12 version if anyone wants to test that. I'm also not sure if this is exclusive to the bramble/Pixel 4a5g device (If anyone knows what they're doing or wants to get ballsy, test & report your results!)
Carrier: I tested this against Tmobile. It depends on how your carrier throttles your hotspot connected devices; Tmobile uses the TTL to determine if its the phone vs a connected device. If your carrier uses that method this should work.
xt_HL.ko: This is the kernel module we're inserting to allow the "iptables ttl set" command. I tested the Android12 xt_HL.ko file on my LineageOS18.1 OS and it does NOT work. This tells me there is some type of versioning. OR: there's an issue with the A12 file...
InCompatibility: (as reported by users in the thread)
ProtonAOSP 12, pixel 4a5g
Steps:
Install Magisk module & read the output; Verify it installed successfully.
Download Termux app from playstore
Termux App: (Shouldn't be necessary if running latest script since that does this step for you on every boot)
su (Grant permissions)
iptables -t mangle -A POSTROUTING -j TTL --ttl-set 64 (should be no errors - if you have errors my kernel is not installed)
Test: Turn on phone Hotspot, connect any device, do a speed test comparing speed on phone should be similar to the connected device.
If any limitations/blocks: (Not sure but maybe http vs https is blocked sometimes)
Install VPN Hotspot app (Green key icon): "Wi-Fi hotspot" ON, wlan1 ON, DISABLE "Tethering HW Acceleration" in settings
Issues:
After running the iptables command you get this error: iptables v1.8.4 (legacy): unknown option "--ttl-set" Try 'iptables -h' or 'iptables --help' for more information. This means the module was not loaded (or isn't compatible. Assuming the correct version was selected, there's no fix. Likely your OS isn't compatible with this module. If anyone has additional troubleshooting to add feel free to chime in.
Technical Additional Info:
ttl_magisk_L18.1: This contains the xt_HL.ko file compiled from the lineage-18.1-20220102-nightly-bramble-signed repo
ttl_magisk_A12: This contains the xt_HL.ko file compiled from AOSP kernel: android-msm-redbull-4.19-android12
Updates:
* I updated the thread title since no one reporting the Android 12 kernel mod is working (only 11 works this far)
* I added "ttl_magisk_L19.zip" script which runs the iptables command for you on every boot. I just tested this on LineageOS19.1 and it works good. I'm working on testing it on LineageOS20.0...
Based on what @fddm said though, it sounds like a Magisk module like this will not work on stock AOSP because it "enforces signatures on modules". If anyone can confirm that, or a workaround that would be helpful. Also https://forum.xda-developers.com/t/...l-tether-lineageos-18-1.4295601/post-86173703 indicates we'll want to disable IP6 via these commands:
ndc interface ipv6 rndis0 disable
ndc interface ipv6 wlan0 disable
If anyone wants to test & get back that'll be great. With Tmobile I didn't need to do that (yet), but again feedback would be great.
I had checked the stock and Lineage configs and neither had signature enforcement enabled. I only had access to this phone for a couple days, so I unfortunately can't test for you.

So you think this should work on stock? Thanks man! I need my phone for work so can't put it offline for hours atm, but maybe over the weekend I can. I'd like to reflash android 12 stock & see if this works. I'd have to assume there's some interest in this... Someone else to test...who knows
hi, I am on ProtonAOSP 12, pixel 4a5g, tested the ttl A12 zip file. But it gave me error when trying to run the iptables command as per your instruction. So I guess it is not loading the module maybe

Apologies for your results. I just updated the OP with an "Issues" section I'll update with issues reported, and any fixes if we discover any. I've only successfully tested this against LineageOS18.1, and was only hopeful it would work against other OS's. Just for kicks, since it's a pretty simple/quick process, you may want to try the ttl_magisk_L18.1 version. BTW that entire command is case-sensitive in case someone didn't know (Eg. Iptables... will not work; iptables... will).
Regarding the fix for your issue...I think Proton is based just on AOSP, and nothing to do with LineageOS. I wouldn't think that would matter but pointing. I would've made an Android12/LineageOS19.0 module but it isnt official yet for this device. I'm not sure how willing the Proton folks would be, but the next logical step would be to have them add the following options to their ProtonAOSP12 "redbull_defconfig" file (or equivalent), build it, and send me over the xt_HL.ko file. Then I'll add a magisk module for that for you to test.
Side note: there are 4 recent AOSP kernel versions for this device. So if there are compatibility restraints with versions, I'd guess we'd have a maximum of 4 to deal with, depending on what OS you have. I don't know for sure, but wouldn't think your ROM being AOSP, LIneageOS, or Proton would make a difference, since typically custom ROMs only customize overlays, features, preferences, 3rd party SW, etc - they don't typically rewrite the kernel for example. But we'll find out. The modules I posted reflect LineageOS18.1 (should be android-msm-redbull-4.19-android11-qpr3 but I didn't verify; though this does work with a June 2021 build which is likely android-msm-redbull-4.19-android11-qpr2 or before) & Android12 (android-msm-redbull-4.19-android12). I don't have one for android-msm-redbull-4.19-android12-qpr1 yet, but there's a chance that's what you need. Recent bramble kernels:
android-msm-redbull-4.19-android11-qpr2
android-msm-redbull-4.19-android11-qpr3
android-msm-redbull-4.19-android12
android-msm-redbull-4.19-android12-qpr1

Another note: it appears Proton does quite a bit of work with the kernel, mods/etc (eg. Features list here: https://forum.xda-developers.com/t/kernel-pixel-4a-5g-proton-kernel.4194685/ ). I'm not sure if you flashed their kernel (1 ROM says its not required), but if you did that may explain the incompatibility - but I'm just guessing.

Not at all, I am just using the Proton without the Proton Kernal (this is optional). If not mistaken, the Dev mentioned somewhere that by default, the kernel is same as stock

Hi, I followed the steps and I am able to get this to work after making the changes to iptables. I did notice that if I reboot the phone the changes are not persisting. Is there any way to fix this?

That is odd. That iptables command should be persistent across a reboot. The steps in the OP are all I did. In fact once I get it working it's hard to undo it! Like I'll delete the iptables rule, reboot, and usually I still get I throttled data. Eventually it'll break again after messing with it. No clue why. Hopefully sometime else can chime in. For reference, please post your OS, build, kernel, assume Pixel 4a5g?...

iptables rules shouldn't be persistent unless you add them via script at startup. If anything, the opposite should be true. I know some devices will refresh their firewall rules after some time, at which point you have to add it back.

I have a very hard time believing that module worked for your device, are you sure your kernel doesn't already have xt_HL builtin? That aside, were you having issues before trying this? It's probably a compatibility issue between your unnamed provider and the platforms you want to use. If that's the case, just try out a bunch of VPNs until you find one that works and use it with VPN Hotspot.

yes its running according to magisk log. I was previously on pixel exp. rom android 12 and termux cmd ended in error
that is why I switched for the kernel. and from what i can tell all data is used as talk text data.... as my wifi hotspot 15GB still shows i have only used 2GB (which i have). as far as my B.S. problem I think it has something to do with multiplayer servers. it works fine on wifey's hotspot same carrier LG stylo 6 stock..

If I'm understanding - it works, but some devices connected have random results? TMobile, or any cell phone provider, are known for issues with VPN, etc, so that doesn't surprise me. And a total guess, but TMobile uses cgnat & ip6, so maybe that's causing issues as well - but not sure what provider u have.

Hey all,
I was trying to watch beacon frames transmitted by my access point, but had no capable hardware in my house to sniff it. Or did I?
Turns out, Pixel 6 / Pixel 6 Pro can do it. Here's my howto.

chrisf4.blogspot.com
Short answer: Flash an aosp_raven-userdebug build from Google, then use wifi_sniffer and some related system properties to configure frequency and bandwidth, and enable monitor mode using a special firmware that is shipped in the userdebug build. Then, use tcpdump on the newly created radiotap0 interface.
Enjoy,
Chris

Hi x56x, a dependency for that is "3. WiFi chipset that actually uses the QCACLD driver/firmware."
Since Pixel 6 uses a Broadcom WIFI chip and not Qualcomm, you would need my directions for Pixel 6 and 6 Pro.

I actually used these commands for qualcomm on a rooted stock A12 P6P and it worked flawlessly. Never got a chance to mess around with packet sniffing. I am curious as to how you found this? Maybe someone can take a deeper look at the firmware and start working on packet injection.

raven:/ # ls -l /sys/module/wlan/parameters/con_mode

Are you on Android 12, 12.1, or 13? I got it to work on 12 when the phone first came out, so something had to have changed.
I worked on Pixel 6 kernel software and this didn't change..
Just to be sure, you can sniff WIFI packets that the kernel sees, without any changes and just root, using tcpdump. If you want to see other traffic that the WIFI chip would normally filter out, you need monitor mode and you need to load this separate firmware to get into monitor mode.

Tried to install today, Didnt see a Release on the Github page, tried to manually compile the magisk module and just get error "Failed to unzip" in magisk. Any ideas? Thanks regardless, been searching up and down for the Wifi_Sniffer binary
try this zip. github is weird sometimes with magisk modules source when you download it.
as for the binaries and the firmware they are located in the system/vendor folder in the zip

on a side note, i am getting "permission denied" while trying to run "wifi_sniffer start". on a rooted pixel 6 pro, factory image but have ro.userdebugging enabled. adb sees the process just does not have access to view it. Could be my goof since i am not using userdebug build
go to data/adb/modules look for the module and go to system/vendor/bin and change the permissions with
chmod a+x wifi_sniffer
chmod a+x wifi_perf_diag
i guess i need to fix that somehow

It starts now!! time for me to fiddle with this "Unable to open /sys/wifi/firmware_path, Failed to up radiotap0" error, surely i made a mistake.
i havent had much time to play with it. i was really hoping someone could figure it out and recount thier steps here.
i noticed some sepolicy stuff reguarding wifi_sniffer while building a few roms for pixel 7, theres an incomplete package to build it. right now adding the package to the device trees to build enables the sepolicy for it but thats it. we may not be able to use them with out using a beta preview until android 14 is released. thats speculation though, cause i dont know.
but please anyone that gets this working please share your steps

I actually got useful help from ChatGPT. dmesg has an output of [wlan] wl_cfg80211_alert ←[0m: In : error alert eventing, reason=0x6, which indicated firmware corruption. Will start looking at the firmware file its self momentarily.
This is how i get wifi_sniffer to work. first download and install the nethunter firmware magisk module. check permissions of the binaries.
next reboot your device and disable wifi and data. This must be done in order to restart the wlan in monitor mode
now open terminal emulator and either type or copy and paste the commands below
in su shell
