CM6.1 wifi problem

I know this question is answered somewhere I just can't find it. I watched the you tube video on how to fix the wifi problem in the cm6.1 build but when I put the info into terminal emulator and reboot, it's not fixed. I enter the info just as it is in the info with the video, anyone else having problems?

I also had the same issue but I found the reason why. I actually used slightly modified versions of the commands via adb. The youtube video I referenced was:
http://www.youtube.com/watch?v=cvS4EvS0PAw
The commands I run were:
Code:
# rm -f /system/lib/modules/*
# cp -f /sdcard/hotfix/* /system/lib/modules
# chmod 755 /system/lib/modules/
I noticed that in order for this to work I had to do two things:
1.Make sure the Wifi is turned off before you run the commands.
2. Delete/Forget the Wifi Network that you attempted to connect to. Trying to reconnect with the same remembered network did not work. You have to delete it again.
Hope this helps.

you mean it worked this time around right?

Are you guys talking about your wifi timing out? Or just not being recognized at all?

Tried the one on youtube no joy
Tried the and it worked first time
# rm%-f%/system/lib/modules/*

the % symbol represents spaces
hope this helps

I will try it with the percent symbols to see if it works for me.
Not talking about wifi timing out, phone says error when you try to connect to wifi. Will not connect at all.

I did a hard reset a few days ago and those files disappeared from system/lib. Now I can't get the files to copy from sd card to root. Any way to fix that?

[HOWTO] Wi-Fi Tethering on MIUI

Start the rom's wifi tether from Settings > System > Tethering & Portable Hotspot > Portable Wi-Fi hotspot.
You should be able to connect to it, but you won't be able to use the Internet.
Now set up the NAT manually, for which which I've found a tutorial online*. We'll want to connect ppp0 to wl0.1.
Open a root shell and enter the following. (Note that /proc/sys/net/ipv4/ip_forward is set to 1 automatically when we enable the rom's tethering)
Code:
iptables -t nat -A POSTROUTING -o ppp0 -j MASQUERADE
iptables -A FORWARD -i ppp0 -o wl0.1 -m state --state RELATED,ESTABLISHED -j ACCEPT
iptables -A FORWARD -i wl0.1 -o ppp0 -j ACCEPT
Now you'll be able to access the Internet from your computer.
Disclaimer: I haven't tried turning it off yet. I assume you just remove the three rules and then turn off the rom's tethering.
*new users can't post links, so just Google "linux nat"

ON miui rom?

This works great. Is there any way to make these commands happen each time at startup? (Settings are lost on reboot)
Also does this have to run after wireless tether is enabled? Or does that not matter.

i tried putting the commands in the init.rc under "on boot" but when i rebooted the file reverted back to what it was before i edited it and the backup of the original file i made was gone (init.rc.bak). can someone help me do this? i think the built-in tethering is just more convenient to use rather than installing barnacle and i'm hesitant to use it anyway cuz wifi tether didn't work for me
edit: i guess barnacle does work but i would still like to get this working if it doesn't get fixed in the next update

Does anyone happen to have any insight on this? I know this is an old thread...but I agree with this dude.

You need to unpack and repack the boot.img to make it stick. The init.rc is inside that.

[SCRIPT] Change Hostname v6 08/07/2012

This will also be the last update to this script for the foreseeable future. Someone else is more than welcome to take what is here and run with it though.
08-07-2012 fixed a few typos and problems with quotes.
01-29-2012 added some variables to check for the existence of things and get correct paths.
01-06-2012 fixed hostname path.
01-02-2012 Updated to truly work on all devices.
Check it out and let me know what you think.
Big thanks to cdesai for pointing out a nice little enhancement.
This is version 5 of this script.
This script is designed to change the hostname of your device so that you can access it through your network by name instead of android_0123456789ABCEDF.
Your device will also be able to be seen at your router by the new name as well.
Code:
#!/system/bin/sh
#change devName to whatever you want.
devName="changeMe"
#random variables
devHostPath=$(which hostname)
devGetPath=$(which getprop)
devSetPath=$(which setprop)
if [ "$($devGetPath net.hostname)" = "$devName" ]
then
echo "Device hostname does not need to be changed."
else
echo "Device hostname is being changed to $devName."
$devHostPath $devName
$devSetPath net.hostname $devName
if [ "$($devGetPath net.hostname)" != "$devName" ]
then
echo "Device hostname has not been changed."
else
echo "Device hostname has been successfully changed."
fi
fi
Download Hostname.sh
Download Hostname.sh to your device.
Use a text editor to change the "changeMe" in the script to whatever you want. [Keep the quotes]
Use Script Manager to run the script.
The script output will tell you if the command has completed successfully.
Once it has been run your device will be named whatever you change the "changeMe" to.
*Additionally, this script should be able to be run on any device without issues but I have only tested this on Galaxy Nexus AOKP and Droid Bionic Eclipse v3.0.

Can anyone confirm this worked for them? Doesn't seem to be working for me.

What's the output when you run it?
And when you run it a second time?
You can check at your router as well by logging into it and checking the DHCP leases.
Oh, I figured this was assumed, but you have to have root and run it as root.

Not all roms will have bash, and even those which have it is mostly in /system/bin

Yet another idea, you can specify the host name while executing the script as an argument (quick changes )
You can use read devname and if it's empty you can get model no. From build.prop

I left it static so that it can be run at boot and will always have the same name. The model could work but it is more for changing the name to something you want rather than being dictated what it will be.
Oh and depending on your model you could have a space or other special in it.

LG Revolution
On LG Revolution running GingerVolt 1.3, I had to change /bin/hostname to /system/xbin/hostname.
The script can be modified to determine the location of hostname command , rather than hardcoding the path.

I am working on a V5 of this which should be released within the next 2 weeks that should address almost all issues. It works as is on some devices but not all.
I have also found from my testing that setting the hostname is inconsequential and will only appear when you run the hostname command.

Thanks! This is the path on the Galaxy Nexus (ICS 4.02) and i was able to get it to update successfully.
However, if this does not update the host name that is sent to my wireless router, the point of the exercise is moot to me. But at least I learned a little bit more about my phone!

This has been posted elsewhere, but to set the name set for the Wifi DHCP request:
Code:
echo yourphonehostname > /proc/sys/kernel/hostname
Obviously, this needs root. You can stick that in a new or existing script in /etc/init.d.
No need to reboot the phone for this to take effect. Stop and start wifi to get the phone to request a new DHCP lease. Note that if your phone was already connected to a router, then the new name might not show up immediately. You'll need drop the previous name from the router dhcp client table by either waiting for the lease to expire, rebooting the router or expiring the lease manually (e.g., in Tomato Admin GUI, click on the remaining lease time under lease column in the Status -> Device List page.)

I can't thank you enough for this, it's been fantastic so far! I only have a few questions, as I am extremely new to arch linux...as in this is the first time I've used anything aside from debian in the linux world.
To start, how would we go about changing DE's? I've downloaded a couple, but i get errors every time i try to start one saying that another window manager is already running. With ubuntu one just logged out and chose from the log in screen, but there doesn't appear to be a log out process for this, i get a black screen every time i do. Other than that, are there any general programs/settings/tweaks that you would suggest applying? While this is very nice, it still seems to be missing some basic functions, such as putting the screen to sleep and having a set system time.
Despite all of that, this has breathed new life into my tablet, you're doing fantastic work and I hope you only continue to make it more amazing!

Take a look at the .xinitrc file in the home directory. It's a hidden file so you may need to "show hidden" or give an editor the full path (/home/user/.xinitrc)
The file runs the following by default:
Code:
exec startxfce4 --with-ck-launch
You can change everything after `exec` to the script for a different DE, such as `startkde`. If you don't know the command, there should be a list of session templates in /usr/share/xsessions/. Inside each .desktop file there's an "Exec=" line, everything after that is the command to sub in.
My crappy bash skills threw together a quick command to get a list of installed xsessions:
Code:
grep "Exec=" /usr/share/xsessions/*.desktop | sed -E 's/^Exec=(.+)$/\1/'
The output on the default rootfs will just be "startxfce4". If you have KDE another line should output "startkde", and so on. Put the command in your .xinitrc (making sure to replace the current one) and then reboot as there's no proper way to log out.

First of all, thanks for the help! Unfortunately, I appear to have done something incorrectly, as the Linux partition will no longer boot. That code didn't return anything but a ">", although as I type this i realize I may have needed to be root...haha, regardless, I tried to edit the .xinitrc file with "exec /bin/usr/startlxde", which is what was after "exec=" in the xsessions directory, nothing happened after waiting quite a while after boot.
I suppose I'll have to reflash the entire partition, considering i can't access the filesystems to change it back. Ah, the wonders of linux!

Sorry if I repeat my question,but how can i activate the keyboard without using a pc with linux ?

You should be able to gain access easily via Recovery. Just adb shell in, mount /dev/mmcblk0p8 /mnt and look in /mnt/linux - that's your root file system...

Without using a PC... Hmm, that could be tricky. If you're in Android, and you add this line to the top of /data/linux/home/user/.xinitrc
Code:
maliit-server &
(before the exec line)
It should give you the virtual keyboard when you restart into Linux.

I was actually able to just use the terminal emulator in android to navigate back to the .xinitrc file, turns out i wasn't supposed to leave the "--with-yadda-yadda" bit, so i got lxde working...and as it turns out, i don't like it nearly as much as the DE you included, so i'll be switching back to that!

First off: thank you SO much for your hard work at this! My tab has never browsed the web this well. It's better than the desktop I'm sitting next to. Arch is amazing!
Just a few questions. Do we have basic tab controls yet? I'm looking for, specifically:
Brightness Control
Enable/Disable Touchpad
Volume Control
Sleep/Suspend/Hibernate
Especially that last one! As far as I can tell, if I'm not going to use the tab for more than a couple minutes, it's apparently best to shut it down or reboot back into Android so it can "sleep". Or plug it in. I know we're rough around the edges yet, but is this stuff in, or no?

I don't think sleep/suspend/hibernate is implemented at all quite yet. The backlight seems to turn off completely when the screen times out though so you can fake having a low power mode, though obviously true sleep would be nice.
As for volume control, use pavucontrol. You may need to install it with `pacman -S pavucontrol`.
For brightness ... there's no good way to do this as far as I can tell. XFCE has a brightness control applet you can add to the bottom panel but it doesn't seem to work, and most of the usual packages (e.g. xbacklight, etc) don't detect the backlight device. Oddly enough I gave e17 a try and its builtin brightness applet worked fine, I wonder what they do differently ...
At any rate you can control it manually: the file /sys/class/backlight/pwm-backlight/brightness has a 0-255 value which controls the screen brightness. Note that you need to run the echo command as root
Code:
# echo "1" > /sys/class/backlight/pwm-backlight/brightness # minimum brightness
# echo "255" > /sys/class/backlight/pwm-backlight/brightness # maximum brightness
# echo "0" > /sys/class/backlight/pwm-backlight/brightness # completely turns off backlight. use with care
Setting it to zero makes it next to impossible to see the screen. I ended up having to ssh into the device (or reboot) to get it back.

I modified the file through a PC and It works ! Thanks, no problems with wifi

Sleep / Suspend isn't implemented yet.
But, I did a bit of testing, and the TF should last for about ~40 hours with the screen off, and the processor in the Low Power mode (which it does automatically. Obviously, it's still wasteful compared to proper suspend, but it's not too bad.

Really liking this so far, other than managing to break wifi once, which I fixed by doing a quick re(install I guess is the proper term). Any chance of a future release having SLiM or something setup out of the box(I'd do it but looking at some of the guides, we are missing some files(?) :s) either that or is there a way to autologin a new user other than the default one named user?
(edit for more info) I've tried following a guide I found on the arch wiki which had me modify [email protected], but it didn't boot so I had to edit it back to the default.
Thanks for all your work cb22, and thanks for taking my advice and switching file hosts

So, does Adobe Flash support work at all in Chromium? I haven't gotten it to recognize the plugin at all. Any way to get this working, or is it just gonna keep bugging me to install it?

In theory you should be able to install a proper display manager without too many issues:
Code:
# pacman -S lightdm lightdm-gtk-greeter
# systemctl enable lightdm
...though when I tried this the DM would never actually be run. I was able to run it manually over SSH without issues (both lightdm and slim worked, more or less). I'm in the process of investigating why it isn't run at startup like it should be, whatever the issue is doesn't seem to be related to the display manager itself.

I have an issue with wifi.
1: The WLAN do not find any Network with Channel 12 or 13.. I think I must change the region in germany, but where?
2. The WLAN do not connect, they search for an network adress and after 30seconds they ask for wlan key again.. the key is correct and my router shows the connection.. but archlinux means the key is wrong.. testet with router und smartphone wlan hotspot..
3. 3G not connecting, i have create a profile for BASE Germany, but they do not connect.
UPDATE:
for 2: Sometimes they connect and I can surf. But the ping are more then 600ms.. After few seconds the connection lost, sometimes they connect again, sometimes say ask for wlan key again.
Maybe you can help me. Sorry for my bad english.

Could any of you guys find out if you have a process running in "interruptible" state named "kinteractive_lo"?
You can check that using "top" in CLI or installing gnome-system-monitor. I guess the standard xfce task manager works as well.
It's driving me nuts and I believe is one of the reasons why I have to hard-reboot my tablet, since invoking reboot with --force works perfectly.
Thanks in advance!

I bought this device specifically because I do a lot of work on linux in command line world and I though it would be the perfect device when combined with the Logitech Pro keyboard and Complete Linux Installer (it's an app on Google Play). It turned out to be quite a bit of work getting everything working because of Knox and SELinux. Eventually I got a custom kernel working that allows me to toggle SELinux between permissive and enforcing.
I attached an Odin flashable tar that works on the SM-P900 (wifi version). I am on the North American version, so I have no idea whether it will work in other regions. If you flash this kernel then there are a few things you need to know:
I'm assuming you already have root on your device.
When you boot it will still be in "Enforcing" mode. This change simply allows you to use the "setenforce" terminal command or any of the apps on Google Play that do this for you.
You might experience some wifi weirdness after you flash the kernel. You just need to open up /system/build.prop and change ro.securestorage.support from true to false and then reboot to resolve the issue.
If you have a different version of the device or want to compile it yourself for any reason I wrote an article describing how I compiled it here:
http://graemehill.ca/compiling-permissive-android-kernel/
I also did a few other things to fix the keyboard and get linux running properly, so if you're interested in that I described my setup in more detail here:

Thank you for this!

trying to build kernel
I'm trying to follow your guide to compile a kernel from source. I have installed (on my Win 8.1_64 PC) Android SDK/NDK. GnuWin32, JavaJRE, and downloaded SM-P900 kernel source.
I'm getting errors at "Apply Kernel Config" step.
here's the output: http://pastebin.com/yFqDrNY8
Thanks for your help

It looks like you're in Windows. To my knowledge it is not possible to compile a Linux kernel in windows. I would recommend downloading virtual box and installing some Linux distro in there. This is what I was talking about in the "environment" section at the top of the article.
For android development I find that you need access to a lot of tools where some are only available on Windows and others are only available on Linux so a Windows PC with a Linux VM is ideal in my opinion.

Oh ok, no problem. I just misread the guide. I've setup a build environment in a vm before to compile aosp for my Nexus 10. Shouldn't be too hard to do it again. I recently rebuilt my pc so the vm I had got nuked.

ok I got my Ubuntu VM up and running using this guide
http://forum.xda-developers.com/showpost.php?p=50748836&postcount=25
installed android NDK to ~android/NDK, and unzipped the kernel source to ~android/kernel
followed your guide to build a SELinux permissive kernel but i'm getting some errors when trying to compile. here's the output:

EDIT: retried doing the EXPORT command and now it seems to be compiling

When you export a variable in the terminal it only exists for that one session, so if you open a new terminal instance you need to run the command again. If you want to set it permanently normally you can just put the export command into ~/.bashrc

Oh I see. I'll give that a try. I was able to create a new boot.img following the rest of your guide. I have yet to try flashing it though. Will have to find some info about all the kernel options that can be set. Hopefully be able to integrate HMP to get all eight cores running at the same time.

Cool, let us know how that goes. I wonder how much it would affect battery life.

I tried to install this using VBox Odin and I couldnt get it to work. Tried using BOOTLOADER and also PDA. Not sure the correct one but neither worked for me. Also, Moblie ODin hasnt yet worked but when it does, things will be much easier for me at least.
I have a newly rooted SM-900. I will have to find time someday to compile the kernel against what I have. Must be a slightly newer version than the one you posted. That is only thing I can think since I just got my 12.2. Thanks for the detailed info.

Camera?
Hey, thanks for the great kernel. It's working as expected to enable permissive mode, but I'm having one issue with it. When I use your kernel, the camera is disabled (says something like "Camera Failed"), and it won't work even when trying different software besides stock, like Google Camera. Anyway, clearing cache, etc. doesn't do anything, but the camera works again when I flash the stock kernel. Is this related to permissive mode or something else with the settings?

The camera fails for me too. I dumped a logcat and isolated the issue here:
W/ActivityManager( 2746): Permission Denial: get/set setting for user asks to run as user -2 but is calling from user 0; this requires android.permission.INTERACT_ACROSS_USERS_FULL
V/ApplicationPolicy( 2746): isApplicationStateBlocked userId 0 pkgname com.google.android.GoogleCamera
But... the camera is not a huge deal. It did, however, break wifi. I did not get a logcat of that yet, but I would assume it is also a permission issue.

Wifi works for me using the fix mentioned in the OP. Also, thanks for looking into the camera issue. I agree it's not a big deal, and it's easily fixed by flashing the stock kernel, until someone figures out a proper fix.

Wow, I totally missed that entire line in the OP... You literally just made my whole day. I fought this all day long, desperate to get ubuntu working. Thank you for pointing that out.

I get "xt_mark.h" is missing (no such file or directory) error. Any idea why that may be?
I'm using the source for p900 international hoping that I may sidestep the camera issue that way (by enabling permissive to the international kernel I mean), but as it stands it does not compile.
I've googled it but until now it was/is to no avail...

Hey Graeme H,
we both have the same intention. I am downloading the international Kernel at the moment and will compile it again for you guys. The download takes a little longer as I am at vacations.
I am going this route: doviak.net/debian-kit/debian-kit_p00.html . In the future I would like to have arch linux running on this device but a customized debian would be okay for the beginning, too.
Eventually I will try to use framebuffer instead of vnc or something like that. I would love to use sublime-text and dwm on that device with that resolution
Good luck guys. I will try to update.
Edit: hehe I have dwm in front of me now and the resolution is so high that I am barely able to read
Compiled the kernel and flashed in on my device but my camera is still not working. Maybe we need to edit the config:

Rather than each people compiles its kernel, could someone put a link to download the international kernel compiled? I think this would allow more people to get this kernel. Thank
