[Q] Unable to adb push wpa_supplicant for ad hoc visibility

Hi,
I'm trying to connect my SGS (2.2 Froyo) to an ad hoc network here.
I know about virtual access point but I don't want that for some reason. Please do not suggest that here. I want my SGS to connect to an ad hoc, that's it.
Have looked at a lot of forum posts, blog posts etc. on this and tried many ways to push wpa_supplicant to /system/bin but it has been very unlucky.
First of all, I've rooted my SGS with SuperOneClick and everything was fine there and I've been granted with Superuser access.
Below are a list of my failures in attempting to push/copy/move/overwrite the wpa_supplicant (in)to /system/bin
adb push wpa_supplicant /system/bin
failed to copy 'wpa_supplicant' to 'system/bin/wpa_supplicant': Read-only file system
Click to expand...
Click to collapse
adb remount
remount failed: No such file or directory
Click to expand...
Click to collapse
adb push it to /mnt/sdcard then attempting to move wpa_supplicant from sdcard to /system/bin using Root Explorer
tried su - mount too but it doesn't help (or maybe I did this wrongly)
Will appreciate someone to guide me through this.
Thanks!
Joseph

with root explorer click on mount r/w

Thanks a lot for your help, luismanson.
However, that doesn't solve it.
Here's what I did.
Open Root Explorer, click on mount r/w, browse to mnt/sdcard, move wpa_supplicant, browse to system/bin, paste.
Unfortunately, the size doesn't change and wpa_supplicant still remain in mnt/sdcard.
Then I tried copy wpa_supplicant to / directory (root), I can't find that file there too.
Is something wrong?

im new to i9000 but why dont you:
adb shell
su
cat /sdcard/wpa.. > /system/path/wpa
and see if it works
try that or post the link and i will try by myslef

It returns with this message:
cannot create /system/bin/wpa_supplicant: read-only file system
Click to expand...
Click to collapse
What do you mean link? The person who provided wpa_supplicant never showed any specific instruction. He/she just said, push the file to /system/bin or push it in recovery time.
I tried that too. Boot into recovery mode but adb couldn't detect the device when it's in recovery mode.

hey i didnt replaced this file, but yesturday i mess with other file, you just need to remount /system rw
either use root explorer or:
busybox mount -o remount,rw /system
and then try to replace the file

Thanks a lot for your help, luismanson!
I managed to overwrite the file using:
Code:
busybox cp /mnt/sdcard/wpa_supplicant /system/bin
And I'm now connected to ad hoc with SGS Froyo!

Sent from my GT-I9000 using XDA App

Not sure about that.
I'm just some newbie who are trying things out.
Couldn't risk making a fake guide and end up "sabotaging" others' phone. Lol~
Maybe you should request someone that's expert in this to make a proper one.

hey anyone help ...i bought my IDEOS phone with android froyo... i need to configure it to accept adhoc connections...anyone guide me oh how to push the wpa_supplicant and get the adhoc working ...am a new to android...am using windows 7..

Where did you get the file?
I'm trying this, but i don't have the correct file. The wpa_supplicant i'm trying to replace is corrupted or not appropriate, and it causes the force-close vibrate (not actual force close) whenever i turn on wifi, and it turns off after saying 'unable to scan for networks'. and also something about an illegal argument.
josephting, could you tell me where you got the file that made yours work, so that i can try it too? Mine is a galaxy ace, not an S, but they're similar enough to be worth trying.
Also, my Ace doesn't have that WPS icon. Not supported on Ace?
Thanks.

anyway, please, the file you used. thanks.

Currently, I'm not using Samsung's Android anymore. (Formatted into MIUI)
So, I don't have the file. Try look around again for the file.
I'm not sure, I didn't paid any attention to that.
Maybe it's because SGS support WPS?
Sorry that I couldn't be of any help.
Just create a new thread and wait for someone who really can help to help you out.
Good luck.

i have a tablet running android 2.3.3 rooted with superoneclick...i follow the instractions to copy paste the wpa_supplicant using root explorer.but when i open my wifi shows false and my table restarts.what i do wrong...i am lucky that i made copy of the original file

[BATTERY PERCENTAGE] different battery mods showing in percent %

Battery percentage mod by SMABERG
Ive made theese only for myself, but decided to share em cause of demand.
i dont take any responsible for damage to phone or malfunction, theese work on my phone, so they are tested though.
For theese mods to work, and for it to not go into bootloop, you got to put phone in bootloader(power on while holding vol.up) the use ADB from android SDK and run in commandprompt (in windows, startmenu, run, cmd) then input this command. Dont forget to enable usb debuging
adb shell mount /system (thanx for reminding me on this s60mike)
adb push framework-res.apk /system/framework/
A big thanx to theimpaler747 for making this mod work. and also for the gingerbread battery below

i have bionix rom works? it possible flash zip or only work to adb push? thanks

funny... adb does not recognize my device in bootloader mode, but fastboot does.
But when i turned on the phone in usb debugging mode, adb recognise my device.
So with the phone turned on, i used root explorer to set the permissions to /system/framework folder and used the above adb command line and it worked!
out of topic : ADB not recognized in bootloader mode but fastboot does, normal?

the blue one looks really sweet, might have to throw those files into tonight's CM7 nightly framework and give it a shot

It'd be awesome to have a battery percentage mod on the cm nightlies!

Also had the same issue but, since I don't have root explorer, I just used Clockwork Recovery to mount the /system and then use the adb push, worked great!

Very good, thanks! One thing, on the green battery with the black outline I think the charging image is a little off from the regular icon. While my phone is charging the icon jumps up and down a bit

[HELP] I replaced my HTC One Launcher And Now I Think I bricked It

please delete thread

good news is, is that your not bricked. Assuming you have twrp installed, go back into recovery, then advanced, then ADB sideload. On your computer (assuming you have sdk installed), open a command prompt and navigate to your platform tools folder (or where ever adb is located) - (cd C:\where ever the folder is ), then make sure you have a rom (viper or stock) in the same folder as adb and in the command prompt do adb sideload nam_of_rom.zip (may take a few minutes)

Either way it sounds like you'll be just fine but make sure there's juice in your battery before trying any of the solutions.

your cmd window needs to be in the folder with the adb tool, normally something like c:adroid sdk\platform tools navigate to this directory in windows explorer the hold shift and right click on and empty part of the window and select "open command prompt here"

Change DPI Without Root

PizzaSauce said:
Make use of that super saturated 2k panel!
1. Download the Android SDK
2. Extract it to a desired location
3. Navigate through the extraction to SDK > Platform Tools
4. SHIFT+RIGHT CLICK anywhere inside this folder and click "open command window here"
6. Make sure you have the correct drivers for your phone
5. Turn on USB Debugging and plug your phone into the computer
6. Tell your phone to trust the computer
7. In the command window, run the following command but replace *** with the desired DPI (I use 540)
Adb shell wm density ***
8. Reboot phone to have changes fully take effect.

Just tried this on my S6Edge (changed to 540 DPI) and I love it. Enjoy!

Can you post a screen shot of it. :')

I love that this is making rounds. Thanks for quoting!

Do any of the apps look messed up?

on mac?
Has anyone successfully done this on a Mac? I've watched tons of YouTube videos and tutorials and still can't get it.

I did this on a Mac with no problem. Just followed instructions.

Would you mind helping me out?
1. Download the Android SDK
2. Extract it to a desired location
3. Navigate through the extraction to SDK > Platform Tools - I see "Platform" and "Tools", 2 separate folders - which one?
4. SHIFT+RIGHT CLICK anywhere inside this folder and click "open command window here" - How do I do this on a Mac?
6. Make sure you have the correct drivers for your phone
5. Turn on USB Debugging and plug your phone into the computer
6. Tell your phone to trust the computer
7. In the command window, run the following command but replace *** with the desired DPI (I use 540) - Can you clarify on this step? Same on a Mac?
Adb shell wm density ***
8. Reboot phone to have changes fully take effect.

Once you have everything installed and the phone hooked up to the Mac in USB debugging mode, then start the Terminal app. Once the prompt comes up type: "/users/[username]/library/android/sdk/platform-tools/adb shell wm density 540"
Remember to change [username] to your "username". I also had to replug the phone in twice I believe before the command worked.

If you already have the Android SDK installed, make sure you also have the "SDK Platform Tools" installed, that's what you need to run ADB. If you don't see a folder titled "Platform Tools" you don't have the necessary files. Google around!

How does this effect battery or performance?

Got it finally, thanks for your help. Is there any way to fix the camera app showing the older dpi?

Can someone please post a screenshot of this DPI corrected screen? I'm trying to determine if it's that much more useful than the 5x5 grid option in the Touchwiz Launcher.

Also I have found a way around my home screen issue (I installed the Google now Launcher) and it works fine. Camera and a few other Stock apps still do not work correctly. I am assuming they are not responsive designed and rather are made for a specific screen size.

Sadly i finally gave up and went back to the stock 640. The camera and phone apps were driving me crazy as they were not designed to be responsive. Personally i think that everything on this phone is WAY to large on the screen and it makes the phone look Childish but until they make the Phone and Camera apps Responsive so that they fill the screen regardless of Density then i cannot use this

[TUTORIAL] How to enable MULTIWINDOW and change Density on M Developer Preview

As we don't have root yet on the M preview, here is quick tutorial how to enable Muiltiwindow and change density.
You will need TWRP and Total Commander with adb plugin.
1. Boot the TWRP
2. Go to Mount and check the system checkbox
3. Plug the device to PC
4. In Total Commander go to network/adb/your device/system and find build.prop

"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
5. Copy the file to some safe place for backup
6. Open the file in editor (F4)
7. Change the line
Code:
ro.build.type=user
with
Code:
ro.build.type=userdebug
8. You can also change the density in the line
Code:
ro.sf.lcd_density=480
I prefer 420.
9. Save the file and copy it back (if you change it on PC).
10. Done

Just FYI, there is a much more simple way to change the DPI without root. You just need a single ADB command.
With the phone powered on, just open up a window in terminal (OSX) or command prompt (Windows) like you would to perform fastboot or ADB commands, and type the following:
adb shell wm density DPI && adb reboot
Just replace "DPI" with the desired DPI. So if you want a 420 DPI, this will be your command:
adb shell wm density 420 && adb reboot
Then just hit enter, the phone will reboot, and voila! enjoy your new DPI.

Maybe I'm just tired

Will it cause missing applications from PlayStore as it did every time I changed DPI?
To check, try to download 'Tinder'. Or go to the Store webpage from a computer and try to find an App that it's incompatible with your Nexus 5 (And it shouldn't)

From the resent menu you can set the top and bottom windows.
When u then in some time launch one of them, it is still will be on top or bottom, but another one will be the last used, but it will not be scrollable some or them, or not always. Still a little buggy, . As the new "half frame" app will be on top.
But if you run both apps from resents that you made top and bottom, then they will both scroll.

I flashed a zip file posted by another user to enable multi window. Then did the adb command from this thread and its all working here.
Edit: here's the post I got the zip from. Flashed it and enabled multi window. Then I adb command DPI to 420. Working for me. Hope this helps
