Hello.
I have had problems with my wifi for a few days. When I press the button in quick settings, nothing happens. When I press the toggle in the settings menu, the toggle switches to "on" but turns gray and it doesn't start searching for wifi networks. I have googled around and read xda forums and found out that it's very likely a problem with the wpa_supplicant.conf file in root/data/misc/wifi.
First I tried some advice that told me to rename the file so that the system would create a new one, and then it would work. I renamed it and even removed the file type ending, but no new wpa_supplicant.conf was created.
I tried setting the permissions for the file to 0755 rwxr-xr-x (I was told this is what they're supposed to be) but every time I reboot the phone they get reset to 0660 rw-rw---- and the problem persists.
I have tried changing the ownership of the file to system.wifi with chown cmd command in both terminal emulator and recovery. I have tried changing permissions both with root explorer and chmod in terminal emulator and recovery.
I can provide the file and any information you ask for on request, I'm not pasting it here from the beginning because I don't know what's relevant and what isn't, and I don't want to clutter the post.
Any ideas?

I was trying to get Polaris Office set up and came across the following:
dave_t321 said:
Put PolarisOffice.apk, libpolarisoffice_Clipboard.so and libpolarisoffice.so in a folder and do this:
Code:
cd [your folder]
adb push PolarisOffice.apk /system/app
adb push libpolarisoffice_Clipboard.so /system/lib
adb push libpolarisoffice.so /system/lib
If you're using windows it might be a good idea to correct the permissions too:
Code:
adb shell
su
chmod 644 /system/app/PolarisOffice.apk
chmod 644 /system/lib/libpolarisoffice_Clipboard.so
chmod 644 /system/lib/libpolarisoffice.so

I'm a complete newbie to this stuff and don't known what me means when he says "
Code:
adb shell -> su -> etc..."
Can someone please explain this to me and tell me how I could correct the permissions? I'm already rooted and have the files installed in the correct places but it keeps giving me an error without the permissions corrected.
Not sure why you have to do these things to install Polaris Office...
He means in command line, you type those commands in
adb shell (run a shell in the phone)
su (ask for superuser permission)
and then the next 3 lines, which changes the permissions of those files.
Yeah, like martonikaj said: it's what you write in the command line or a terminal, or whatever you used to install the files to the correct paths. Each line is a command you write and execute.
If you have Root Explorer, or some other file manager that works with root and features permission change, you can do it on your phone:
1 Open the file manager.
2 Locate the file you want to change permissions for.
3 Change permissions to:
Owner: read + write
Group: read
Other: read
4 Repeat for all program files.

I have root explorer and did this for all 3 files... still gives me the "unfortunately, polaris office has stopped working" everytime I open the app
Any ideas?
I wanted to change my device model, so I copied build.prop from another mobile to my mobile. I am already rooted. But unfortunately I did not change the o.s. from gingerbread to froyo in build.prop ( I have android 2.2 FROYO) When I rebooted, there were many errors. It is now showing no sim card. Mobile network search gives error. Effectively, I can not use the mobile. Terminal emulator, X-plore etc. stopped working. Only Rom toolkit free version works and astro file manager works. Other programs are forcefully closed. Needles to say, I must replace new build.prop with new one.
Using adb I can only pull files but can not write as it is in read only mode.
adb root and adb remount works only if you are in recovery mode ? Y mobile does not have any custom recovery so when I boot in recovery mode it hangs.
Superuser has installed su in system\bin directory. But from adb shell I can use su also. It gives permission denied error. Hence I can not remount the system.
I have read similar threads and found that on some mobiles adb root or adb shell su works but on some not.
I am using Vista 32 bit with admin rights, still can not use root in adb.
Please tell me, how can I mount system read-write. I can not install root explore as google play and even internet is not working.
Please help.

activate USB debugging then in console
Code:
adb shell
su
mount -o rw,remount /dev/block/mmcblk0p1 /system
adb push build.prop /system/build.prop
check where is your build.prop

OMG ruscan.calin i COULD KISS YOU! I had tried to change my OG EVO 4G's buildprop file to another phone so that I could purchase & download an incompatible Google Play app. However after I restarted the phone wouldn't start! It would boot into my rooted HTC EVO 4G Android 2.3.3 and HTC Sense 2.1 but it would get stuck on the wallpaper with just the notification bar at the top and all buttons would be frozen. However I noticed when I plugged in my phone to my computer via usb the computer recognized it. I always keep my phone with USB debugging enabled so I thought I should be good right? I have spent the last 4 hours trying to install and setup adb with no real previous experience with it. I am familiar with dos from years ago and that helped me as it's basic procedure, commands, etc. Then I found out how to install the HTC drivers which I needed and then download the Android SDK with adb that's included which many guides show easily. I started the command prompt (cmd), typed my adb devices command and hurray it showed my phone! I connected and quickly navigated to the build.prop system folder! Luckily when I changed the file I made a bak backup and left it in the same folder. Now the main issue was figuring out how to change the naming of the files which I did via usual adb commands (mv build.prop.bak build.prop). But then to no avail I couldn't get it to write due to it being a system read only folder! Arg! Then I found your post on here, above, and typed it in simply leaving out the adb push portion and replacing that with the mv file command instead and first changing the name of the bad file and then replacing the bak file as the good copy! I exited back to the adb main and unplugged my phone. Moment of truth and man was everything flashing through my head at once! I booted up and YESSSSSSSSSSSSSS, it worked! I went back into root explorer and got rid of the offending leftovers and I've learned my lesson! I just don't want to think about what would have happened if I hadn't found this post. Thank you and if anyone else makes this hug mistake let me know and maybe I can help. Moral of the story don't mess with the build.prop or any system folder unless you know what you're doing! Thanks again!
Quick Guide to Fix Android "build.prop" Issues:
1. Find and download USB drivers for your phone by model or type (HTC EVO 4G's HTC Fastboot drivers): http://downloads.unrevoked.com/HTCDriver3.0.0.007.exe
2. Download and install Android SDK and choose adb: http://developer.android.com/sdk/index.html
Guide: http://htcevohacks.com/htc-evo-hacks/how-to-install-android-sdk-and-adb-drivers-for-htc-evo-4g/
3. Run a command prompt from the "c:/program files/android/android-sdk/platform-tools/" directory. I had to copy the command prompt to get it to open there but sometimes a right-click action will do it. The guide below will help just navigate down to "Using ADB" and skip the rest.
Guide: http://www.howtogeek.com/114667/how...y-default-move-almost-any-app-to-the-sd-card/
4. Once you open the command prompt and you're in the "c:/program files/android/android-sdk/platform-tools/" foler type "adb devices" and your device should appear. If it does move on to next step.
5. Then type adb shell and use the ls command to see directories. Then you'll need to navigate to the system folder by typing "cd system" and then type "ls" to look around in the directory (similar to "dir" in DOS). You should now see the bad build.prop file.
6. You'll need to rename the file or push a correct version. First you need to use the "adb shell" command again and then "su" and finally "mount -o rw,remount /dev/block/mmcblk0p1 /system" to make the directory writable (see ruscan.calin post above for additional info).
Note: I only had to rename my build.prop as I already had my old one in the same system folder. You may have to copy the bad build.prop to your computer, edit it and then push it back to the same system directory. These directions are only for renaming files in the same folder. For the info on how to copy the file to your computer and push it back to your phone go to step *10 below or use the guide below it.
7. I already had the bad build.prop in the system directory with my old one which I had named build.prop.bak. If you have this too simply rename by changing the name first of the bad file to anything by typing "mv build.prop build.prop.bad" or similar.
8. Next rename the build.prop.bak to build.prop by typing "mv build.prop.bak build.prop". Everything should go smoothly and move onto the next step.
9. Finally, If no error messages are found, simply type "adb reboot" or "adb shell reboot" (Depending which version of ADB you have). You should be done, your phone will reboot like normal (working, lol) and everything should be working again! YAY!
*10. To copy the build.prop to your phone type "adb pull /system/build.prop c:\" and the file should be placed in the main c:/ directory on your computer. Navigate to the root (c:/) directory and then right click and "open with" the "build.prop" file using a notepad or other file editor. Then use the text editor (Notepad, etc) to change back what you originally changed to mess everything up. There is tons of stuff on the net to let you know what to fill back in depending on your phone model/type. Or it's possible to get a previous version from an old Nandroid backup or similar. Save the changed text file and make sure its named the same "build.prop" and make sure it's still in the root directory (If you're having issues on this step or just want more insight check out the guides and threads below for more help).

Guide 3: http://forums.androidcentral.com/sp...-replaced-build-prop-phone-wont-start-up.html
*11. We've already made the directory writable in step 6 so we simply need to push the file back to the phone. If any error message appear re-do step 6 to make writable again. Otherwise push the modified file back to the phone by typing "adb push c:\build.prop /system/". Back to step 9 above! Yay!
If anyone wants to help cleanup this quick guide or make any changes feel free. I just wanted something so that if anyone else has this issue they won't have to worry or search forever to find a solution. OMG it's 2:30AM, to bed... I ride! LOL
Enjoy,
5th :highfive:
THANK YOU!!! Totally saved me today.
One thing that I noticed. After pushing the correct build.prop, I had to fully power down, then turn back on my Razr for it to load up the fixed build.prop.

Hello everyone.
I have been able to modify the framework-res.apk file to enable bluetooth tethering for UAMDL from T-Mobile
While I was making the changes in there I also removed from it the call to tethering provisioning and changed the csc files needed too.
So this is for stock UAMDL T-Mobile rooted roms.
I have included the files below to install it if you want.
It does go without saying to backup everything first.
Download from Google Drive
Use the following ADB commands to successfully copy over to the framework folder. Does need to be done via ADB.
Copy new framework-res-mod.apk to root of internal sd card.
adb shell stop (this will cause the screen on your phone to go black that is fine)
adb shell mount -o remount,rw /system
adb shell cp /sdcard/framework-res-mod.apk /system/framework/framework-res.apk
adb shell chmod 644 /system/framework/framework-res.apk
adb shell start (screen will come back on and look like phone is booting again)
after that you can use your favorite root file brower to copy and replace the files customer.xml and feature.xml in the system/csc folder.
If after this you are having problems with getting google play to install apps you might need to master reset.
I want to thank elesbb for help with getting this thing to be able to be compiled and also with the adb instructions to get it copied to the phone without needing a custom recovery but just root.
Awesome man. One question though, so wireless tethering works or only bluetooth tethering?
Yes.
Wireless hotspot, bluetooth (my main goal) and wired tether are working.
Ooops I goofed in the customer.xml file with the APN used for tethering.
I used apn epc.tmobile.com when it should be epc.t-mobile.com
For the time being you can adjust that I will upload a fixed copy tomorrow when I can be at my computer again.
Actually was able to edit and reupload from phone.
It is fixed now.
Apk File not shared for download.
Sorry about that.
Should be fixed.
Give it a try again.
this is what I get
c:\windows-sdk\platform-tools>adb shell stop <<<< phone screen doesnt go black
c:\windows-sdk\platform-tools>adb shell mount -o remount,rw /system
mount: Operation not permitted
c:\windows-sdk\platform-tools>adb shell cp /sdcard/framework-res-mod.apk /system
/framework/framework-res.apk
cp: /system/framework/framework-res.apk: Read-only file system
c:\windows-sdk\platform-tools>adb shell chmod 644 /system/framework/framework-re
s.apk
Unable to chmod /system/framework/framework-res.apk: Read-only file system
am i missing something here?
Sounds like the kernel is not running in insecure mode.
Try installing and enabling insecure adbd with this app and try again

Thanks man we'll give it a shot after I get off work tonight and let you know how it happens
Sent from my SGH-M919 using xda premium
So far I thought I had bluetooth working on this since it shows as a option in the tethering program but when go to pair with something it does not see or be able to use that profile for internet even though it is enabled on the phone.
Wasn't able to test at the time since I had to send in my tablet but have came to find out that this was not working.
I will continue to try and see what I missed or what I can find.
If anyone has a idea that would be helpful thank you.

I noticed today that when viewing a files' properties in Solidexplorer, the Change Permissions button was missing.
I made sure the latest busybox was installed and noticed there that "chmod", "chown", and "chcon "are NOT re-linked to "busybox" but left linked to "toolbox". I didn't want to change the symlink without explicitly trying the chmod command (via toolbox and busybox) first to see if it worked.
I opened Terminial Emulator, su'd to root, then navigated to an mp3 file I have on my external sdcard, and issued both
Code:
chmod 777 "file"
busybox chmod 777 "file"
and nothing happened.
No error, but no change in the permission either (it is 770).
Anyone have a clue as to what's wrong?
UPDATE:
The problem appears to be caused by me not being thorough, not SELinux.
In summary, the SDcard is formatted as exFat which doesn't retain Linux file permissions, therefore, issuing a chmod yields no result, but no error. Solidexplorer is "smart enough" to know that fact and so there is not button to change permissions available.
So i found this trying to find an answer on another device i was working on, even though I had searched for this one as well.
Anyway, only thing you need to do is download the files, and use whatever method you desire to put them in /system/bin folder.
Change the permissions of the files to 0755 (and yes I mean 0755 and not 0644) and reboot. Enjoy.
