Hi all,

There have been a couple of threads regarding ad-hoc not working for the NT but I decided to make a new one so it would be easily searchable. Please find below the fix for adhoc wifi. This fix should work for any OMAP4 device that uses version 0.6.10 of wpa_supplicant. The patch for this came from the following link (the diff file). I just applied it and recompiled for our device.

http://xdaforums.com/showpost.php?p=7711198&postcount=6

Download the files attached below.

Turn off wifi.

To apply the fix do the following with adb (you will need root) or just use root explorer. Be sure to do a backup first (included in the adb script below).

$ adb pull /system/bin/wpa_supplicant wpa_supplicant.bak
$ adb shell
$ su
# mount -o remount,rw /dev/block/mmcblk0p5 /system
# chmod 777 /system/bin/wpa_supplicant
# exit
$ exit
$ adb push wpa_supplicant.omap4.adhocfix /system/bin/wpa_supplicant
$ adb shell
$ su
# chown root /system/bin/wpa_supplicant
# chmod 755 /system/bin/wpa_supplicant
# mount -o remount,ro /dev/block/mmcblk0p5 /system
# exit
$ exit

Turn wifi back on. You should be good to go.

I'm very happy to say that my wife will be driving everywhere now as I will be even more inseparable from this lovely little device from now on now that those of us with old tethers are MOBILE!

One thing I noticed using this patch. After installing it the first time you reboot you may need to go into the wireless settings and forget your networks to be able to reconnect.
[Barnes & Noble Nook Tablet] cosmokao:
worked perfectly thank you!
[Barnes & Noble Nook Tablet] zambien:
Glad to hear it. I have been running it for about 2 days between AP and adhoc and haven't had problems yet.
[Barnes & Noble Nook Tablet] qngds:
Using ADB is problem on my machine. How do I do this through root explorer? I assume its much more than save a backup of a file and renaming the new?

Could I open terminal emulator on tablet and do this?

Also, after downloading the files, where would I save them to on my tablet?

Thanks
[Barnes & Noble Nook Tablet] zambien:
It's pretty easy with root explorer.

1. Turn off wifi.

2. Open root explorer. Navigate to /system/bin.

3. Copy wpa_supplicant

4. Put is somewhere as a backup. Remember where you put it.

5. Get the wpa_supplicant from the zip file above. Unzip it and rename it to wpa_supplicant.

6. Take your new wpa_supplicant from your computer and put it on your nook via usb.

7 With Root Explorer copy the new wpa_supplicant and navigate to /system/bin

8. change to read write.

9. Paste wpa_supplicant into the directory /system/bin which you should be in.

10. Change owner to root.

11. Change permissions to:

read write execute

read execute

read execute

12. Turn wifi back on and test. You may find that you need to reboot your nook if it doesn't work at first.

To restore use the same steps starting at step 6 but with your backup.
[Barnes & Noble Nook Tablet] zambien:
whoops, double post
[Barnes & Noble Nook Tablet] qngds:
Thanks so much! I figured up til item 10, but it didnt occur to me to change permissions.
[Barnes & Noble Nook Tablet] ryuhyoko:
Thanks!! works perfectly to tether on my Iphone.
[Barnes & Noble Nook Tablet] Weo:
Thank you for the step by step for us novices.

As a side note, I used ES File Explorer, which shows up on the Android Marketplace on the nook (at least when rooted) to make the switch. I thought I'd add how to do this using this free app.

When using ES File Explorer. I already downloaded and unzipped the new wba supplicant file, and placed in a folder I could access on the device. I also made a copy of the original wba and placed it in an "original wba file" folder:

1. Open ES File Explorer

2. Select "Settings" at the bottom

3. Scroll down to "Home Directory" and change it to "/" (without the quotation marks)

4. Scroll down to "Root settings" and check both "Root Explorer" AND "Mount File System"

5. Backout of settings and try to navigate to "system" and "bin" (if you don't see it try restarting the ES File Explorer program)

From here ES File Explorer can change root files and permissions.

Now you can follow steps 1-9 listed above by zambien. Then...

Once you have replaced the original wpa_supplicant file with the new one under /system/ bin (don't forget the renaming; I used the "copy to" option) you have to:

1. Navigate back to /system/bin and find the new wpa_supplicant file

2. Long press the wpa_supplicant file and scroll down the pop-up menu to "Properties" (should be the last option)

3. Check the following boxes:

-User; read, write, execute

-Group; read, execute

-Other; read execute

I was able to connect to my HD2 through WiFi Tether (came with AmeriCanAndroid) over ad hoc, and confirmed internet access. I did not have to restart the device, but you might have to. I was able to switch between my house WiFi router, and the cell phone WiFi Tether without any issues.

**Update: Issue with reboot. After reboot it keeps trying to connect with adhoc network even though adhoc network it is off (phone off; shows full bars on NT). NT says my home network is out of range. At this point I:

1. Click on ad hoc network and select "Forget"

2. Wait for my home network to show up (sometimes I click on my home network and it shows up as connecting in background; don't know if it matters and just needs time to scan)

It is currently working except for this bug and seems to keep working after sleep. I think it is only a reboot issue. I will keep this configuration for a few days and see if the reboot issue changes.

**Update 2: It seems like the issue is more about waiting a few seconds for the nook to find the networks after sleep and after boots. With the original WiFi file, it was ready right away. Otherwise, works great!
[Barnes & Noble Nook Tablet] downsay:
Flawless first time. No need to reboot. Thanks for everything! This plus my galaxy nexus makes for an awesome combination!!!
[Barnes & Noble Nook Tablet] ianc125:
Worked perfectly first time. Wifi hangs once in a while and I havev to turn it off and back on to kick it back in, but not really a big deal. I rooted my OG droid justs to get wifi to my nook. I love it.
[Barnes & Noble Nook Tablet] ccl13:
Hi, I have installed this with my rooted NT 1.4.1. It appears to be working perfectly but if I switch WIFI off and power off my NT, it will reboot itself at the Nook screen and I have to force a factory reset to make it work.

@zambien Would you please look into this?
[Barnes & Noble Nook Tablet] iferlive:
Thanks dude now I can fully use the wifi tether of my phone
[Barnes & Noble Nook Tablet] wpstewartjr0421:
Change Owner Question...

When I go to change Owner to Root, there's another box below entitled 'Group' which is now showing sd card - I am still having trouble with the Nook recognizing the wifi from my droid x2 - is this something that should be changed to 'Root' as well?
[Barnes & Noble Nook Tablet] renar77:
Thank you!

Its because of this site and all the people on here that share their wealth of knowledge that I get to enjoy an optimal electronic experience and I greatly appreciate it! Thanks! :D
[Barnes & Noble Nook Tablet] rbellis:
where do we go to change the owner? I can change the permissions but no idea where to go to change the owner. Wondering if this is what is keeping me form getting this to work off of my X2 running CM7
[Barnes & Noble Nook Tablet] lavero.burgos:

[Barnes & Noble Nook Tablet] rbellis:
thank you but that really doesn't tell me anything. I changed the permissions but I still don't know how to change the owner to root. The 3 options below the permissions...what are those?
[Barnes & Noble Nook Tablet] lavero.burgos:
To change owner simply long press the file a window will pop up scroll down(like when you go to change permissions) in the list and you will see change owner, another window will show now next to Owner pick 0 - root from the list. If you can't see change owner option then you need a recent version of root explorer.

[Barnes & Noble Nook Tablet] eybarra2:
That did it! Went off w/o a hitch. I used a combination of root explorer and es file explorer. Es file ex to do the unzipping and copying, root ex to change owner and permissions. 1 reboot later and I'm sending this thx thru my phones tether! Thx a mil, guys!

issues

First off, thank you for your work.

My nt is rooted 1.4.0, blocked otas, with cmw recovery installed, not sure if that matters are not, just giving some background. I applied the wpa_sup. patch with adb from my ubuntu 11.10 machine. Once i applied the patch I was able to connect to my og droid through adhoc, shortly afterwards i could switch to my wifi, after about a day I could no longer connect to my wifi but am still able to connect to my phone with adhoc. When trying to connect to my wifi it stalls on authenticating, then reverts to disconnected, then cycles. I've tried forgetting all networks (wifi,adhoc) booting down wifi, rebooting then trying to connect. Ive run fix permissions,wipe cashe, wipe dalvic cashe in the cmw recovery. checked permissions with root explorer, they still match the settings but with duplicate owner slots, both set to 0-root. It is possible that its on the network end, I have a sort of complicated set-up. wrt310n as my main router, and 2 belkin fd7402's acting as waps, all flashed with dd-wrt, secured with wpa2 aes on the 2.4 and 5 ghz bands, but all my other devices (and there are many) are connecting fine. ill try simplifying my setup and isolating any issues on the network end, just wondering if there's anything ive done wrong on the nook end?
[Barnes & Noble Nook Tablet] lavero.burgos:
Hello i applied this fix in my nook but i can't make it work with my desktop computer (windows 7 x64 bits) i set up the adhoc network and it connects... testing? in my nook, also in my pc i see connected and with internet access but it really doesn't connect to the internet, i have turn off my Firewall and antivirus but nada, any hint of what could it be the problem?

My pc has hotspot shield running so i can access to hulu, netfilx, etc from Equador or Canada and i want my tablet to be able to do the same until offical hotspot shield app for android gets released and/or we get tun.ko support.

[Barnes & Noble Nook Tablet] mrVuHoa:
awesome, thanks for your guide :)
[Barnes & Noble Nook Tablet] pajurgens:
I have had some luck with Win 7 (x64)

Make sure that your VPN service is already active when you create the ad hoc network.

I haven't had any luck with security. I can connect my NT to the ad hoc connection and it works fine but only if I have open authentication and no security. If I add security (WAP2 AES) the NT just continuously tries to connect.

Also, my VPN is only partially working (I'm in China) I can get sites that are blocked on the US side, like Pandora, but I can't get sites that are blocked on the China side, like facebook.
[Barnes & Noble Nook Tablet] lavero.burgos:
I'll give that a try and report back

Nook Tablet keeps rebooting

Hi. I have a Nook Tablet with 1.4.1 rooted with the sd card method. I applied this fix to be able to use ad-hoc wifi with my phone. Everything worked and I could use my phone as wifi, until I went to reboot the NT. It keeps getting to the N Read Forever screen then re-starts. After the 6 times it clears the data. Any idea on a fix for this? Anyone else have this issue? I've done this twice now with the same results and with having to clear my data. Thanks

Wifi driver

This is more of a developer question, but I'm too new to post there. I'm looking for a phone or tablet with a replaceable TI WL127x/8x driver. Seeing as how this thread is about replacing the supplicant, can anybody tell me if the driver is a module (typical name = tiwlan_drv.ko) and if there's anything that would prevent it from being replaced?
[Barnes & Noble Nook Tablet] buzzfgo:
Same here... any help?
[Barnes & Noble Nook Tablet] Gerken918:
Same thing apply this, it works great, reboot and boot loop til restoring factory settings. First time lost quite a bit second time had a backup.

Now only adhoc works

Thank you for posting all of this info, I was able to get my ST up and running on the Barnacle network I setup on my OG Droid. The only problem is now the Nook refuses to connect with my home network. I don't know if this is an issue with the wpa supplicant file or if it's an issue with my home network since my Verizon Fios router and my Nook didn't play nicely together when I first got the Nook (I had to set up a static IP on the router to resolve the issue), but since the MAC address hasn't changed I'm not convinced that's the issue. I'll try on an AT&T hotspot later today just to control for that variable but any advice you can give in the meantime would be appreciated. I guess if it's the wpa file I can switch it back out but that seems very cumbersome just switch back and forth between wifi and adhoc hotspots. Would it hurt anything if I left the spare copy of wpa in the system\bin folder, so that all would be involved would be renaming it?
[Barnes & Noble Nook Tablet] mirdreams:
Can't go back

I didn't get a chance to test with a hotspot today as I'd hoped but I did try copying back in the original wpa-supplement file and my home network still wouldn't connect. That makes me think it is somehow related to the Fios router but since it's still showing up in the router with a static IP I'm not sure how to fix it. Any help would be appreciated.
[Barnes & Noble Nook Tablet] mirdreams:
Problem solved

I'm on my home network again with my ST! I'm honestly not entirely sure what fixed it. I tried the fix from http://xdaforums.com/showthread.php?t=1372239 but I also realized that although I was online with my computer, my phone was getting the same disconnect cycle that my ST was getting so I power cycled the router (very much a duh moment not to have tried that earlier) and now everything is working perfectly. Fingers crossed it stays that way. I'm so glad to have ad-hoc and infrastructure working! Thank you for this fix.

Hi

I try to do with my Nook Tablet which is running Jelly Bean (SGT7+CM10+Cherry Picks,By meghd00t.). Unfortunately, i couldnt replace the original ROM file with this thread's file.

Actually, i tried to replace the original wpa_supplicant but Jelly Bean denied to change the permission of original file: wpa_supplicant permission cannot be changed because the file system is READ-ONLY

I used Root Explorer with Root permission.

So, my question is:

1. Can i apply wpa_supplicant of this thread to fix my Jelly Bean NT (i compare the size, original is 648,86K , this thread's file is 298K)

2. If this file doesnt work wit Jelly Bean, can i have solution to fix Ad-hoc network on my NT

Thanks for your answer!

adhoc wifi

zambien--

I have tried this several times on my 16 gb tablet, running either CM7 or CM10. When I do it with CM7, I can see the adhoc wifi, but it won't connect. Every time I try, the adhoc adds another instance of its name as a 'remembered' network, and the adhoc is still visible. I have 'forgotten' all connections, rebooted, no luck. I believe that I have followed the adb script exactly, because they all seem to execute correctly. When I try this adb script in CM10, I can no longer turn on the wireless on my nook tablet. If I put the original wpa_supplicant back in, it works as before and I cannot see any adhoc but all the 'normal' wifi connections work. What ROM and kernel have been shown to work with this?

Tim
[Barnes & Noble Nook Tablet] tcbeachy:
CM9 already works with adhoc.
[Barnes & Noble Nook Tablet] rp201:
if previous posts are saying cm9 has ad-hoc, I'm not will to go back since running cm10 with video fixes and mic fixes. Hoping some has a temp patch since I'm assuming might be on the radar for cm10 final. seems like a "well wanted" feature. thanks in advance.

[Galaxy Note GT-N7000 General] choikugi:
Hi

I am a little worried about burn in issue. So i would like to hide status bar to minimize it. I have heard some galaxy s2 users have this issue.

I tried several launchers and they only hide status bar on launcher screens. When I use application it does not hide it.

I am wondering if there is any way I can hide status bar all the time.

Thanks
[Galaxy Note GT-N7000 General] Spartan2x:
Burn in? Wow, it's been a few years since I have heard that term! I see no reason why the Galaxy Note, or the S2 for that matter should ever have a burn in issue...the technology just does not allow that to happen...

On another not, the Note and the S2 have different screens. The S2 uses a Super AMOLED Plus RGB, while the Note used a Super AMOLED Pentile.
[Galaxy Note GT-N7000 General] choikugi:
All AMOLED have potential burn in issue. See wiki page.

http://en.wikipedia.org/wiki/Organic_LED

Unfortunately it is more likely to happen compared to LCD or IPS as AMOLED as it burns itself.
[Galaxy Note GT-N7000 General] Viamonte:
Unless you're using your Note as a primary display for your desktop and leaving it on 20 hours a day, I don't think there's much of a chance of burning in...
[Galaxy Note GT-N7000 General] xAnimal5:
Unless you're gonna contantly use your Note for 5+ years, don't worry about it.
[Galaxy Note GT-N7000 General] inurb:
This wins silliest post of the week.

AmoLED's are notorious for burning wearing out especially blues and greens. Look at any galaxy S gt-i9000 that have been used for more than 4-6 months and you can clearly see the wearing out of the led's where the notification bar is static.

Static images on an amoled screen eventually wear out the pixels fading them out. This is a known fact and I'm reminded of it every time I look at my galaxy s.
[Galaxy Note GT-N7000 General] inurb:
regarding the OP's question. LauncherPro among other 3rd party launchers only allow hiding of the notification bar on the home screen. There are several google help forum posts asking google to implement a setting that would allow you to hide the notification bar in apps. The official request was denied by google citing that the notification bar is an integral part of the android os and therefore should be constant throughout apps. Now there are apps that require full screen pixel width like angry birds and such but that is only if the developer codes the app to NOT show the notification bar.

Bottom line its up to developer to include a hide notification bar setting as google will not cook it into the OS as an option.

Hope this helps.

Here is the official google response from an android dev http://code.google.com/p/android/issues/detail?id=9063
[Galaxy Note GT-N7000 General] choikugi:
Thank you inurb. Now I understand why I cannot hide status bar.

Thank you again.
[Galaxy Note GT-N7000 General] ragin:
ADW Launcher has a feature that hides the notification bar when you swipe UP on the screen. Apart from that, if we can change the fonts on a regular basis, we might avoid this issue.
[Galaxy Note GT-N7000 General] rxpaul:
Is the process of burn-in similar to that on Plasma TV screens?? Then the solutions (or things to avoid) would be the same as well for SuperAMOLEDs. There wouldn't be any apps available that could facilitate pixel shifting, would there??

I come from the land of LCD, so I'm terrified of any possibility of burn-in on the new shiny monster!

BTW, Go Launcher EX also has the option of hiding the notification bar (and the dock menus as well!)

I've had the PM from the clock on the status bar burned into my Samsung Captivate's screen....as well as the digits from the clock but they're less defined.
[Galaxy Note GT-N7000 General] CGI_Ram:
If you are like me, you use the device 50% portrait and 50% landscape.

Wouldn't that pretty much eliminate the burn in concern?
[Galaxy Note GT-N7000 General] EarlZ:
I had the Wave/S1/S2 all of them had this "Burn-in" or rather burn out issue. The Galaxy S2 had the shortest time of only 2 months of use while the Samsung Wave took about 9 months and the S1 about 4. Only the "M" sumbol and the battery indicator burned in though.
[Galaxy Note GT-N7000 General] KenAdams82:
Hi All,

came across this thread when looking for a solution for SGS1.

it seems that Burn in is indeed a problem for AMOLED screens.

in my situation, I've found a burn cause by Waze (of course, any app that would leave the screen on would cause it).

sadly enough, my phone is only 6 months old and I use Waze ~30 min. a day - not much for a burn you think? wrong!

for now, i've set Waze to hide the point bar and the zoom control, but still many objects on the screen are static - including the notification bar.

does anyone has a good solution?
[Galaxy Note GT-N7000 General] aussiebum:
I'm wondering if "burn-in" has to partially do with the environment the phone is being used in (the other being reason being a bad batch). For example, tropical (ie. "hot") environments may cause screen issues sooner because the screen can't cope with the heat?

I had my S2 for about 7 months before getting the Note and the screen was on around 40-50 minutes a day. Didn't notice any burn-in during the entire time. I always kept the phone's screen out of direct sunlight, and it was winter/autumn during the time I was using my S2.
[Galaxy Note GT-N7000 General] PoisonWolf:
I saw an S2 got a burn in within 2 months for the lock screen. =)

It's not just burn-in, I believe it's a combination of the burn-in and the specific colors in the LEDs dimming (i.e., losing their initial brightness).

It's best to change wallpapers every so often to make sure that the LED colors are wearing out evenly. If not, over time, you'll get weird tints in parts of the screen due to a dimming of certain colors, etc.
