[Q] Turning on Bluetooth in flight mode

Hi guys,
hope this is the right forum.
I switched from iPhone4 now to the new Samsung Galaxy S II with 2.3.3 and brought my bluetooth Sennheiser MM450 which I would like to use in flight.
Anyway when I turn on the flight mode I can't turn on Bluetooth anymore!?
On my iPhone this was possible.
Is there any way to get Bluetooth in flight mode working as I dont wanna have my phone searching for networks during flight.
Any other App/hint etc. for this?
My Samsung is rooted by the way...

Like this?
Otherwise, on a more serious note: http://code.google.com/p/android/issues/detail?id=3289, see comment 42 there.

Thanks.... maybe I am too rookie for that... I installed QuickSSHd and logged in from my Putty but can't issue these commands:
# id
uid=0(root) gid=0(root) groups=0(root)
# adb remount /data
adb: not found
# sqlite3 /data/data/com.android.providers.settings/databases/settings.db
sqlite3: not found
So I searched but following issue:
# find / -iname adb
/sys/devices/virtual/usb_composite/adb
/sys/class/usb_composite/adb
# /sys/class/usb_composite/adb
/sys/class/usb_composite/adb: permission denied

adb is supposed to be used from your PC, need to install Android SDK there, not try to run it from phone shell.

Thanks, will try that out now and just installing JDK and Android SDK R11...

Ok. If you get permissions denied stuff, I would suggest loosely following this one:
http://dylanmtaylor.com/2010/10/19/closer-to-a-proper-froyo-limit-removal-fix/
For the remount /system thing, you need to check the actual device being mounted by running something like:
Code:
$ mount | grep /system
as it differs from device to device.
(Other way would involve getting ro.secure=0 which might be more complex than needed here. You can check what you have by getprop | grep ro.secure)

[Nook HD+] Nook HD and HD+ rooting instructions (now permanent)

How to root Nook HD+ (and Nook HD too, I guess).
(Thanks for some useful ideas to sparkym3: http://forum.xda-developers.com/member.php?u=4411543 )
(tested only on 2.0.0 version (as comes out of the box), also works on 2.0.2
Get one of the attached files: root_win.zip if you are on windows, or root_unix.tgz if you are on Linux or Mac.
unpack the file to some dir and run "makeroot" on Windows or "sh makeroot.sh" on Mac/Linux
After a couple of reboots you should be able to do
adb shell and issue a "su" command in the shell and get the root prompt (#).
Thanks to someone0 for his prior investigations here.
Known bugs:
Superuser.apk does not really install because package manager could not be contacted.
Oh, and I think you'll find this interesting too:

Hai.
Kind of a two-fer, eh?

I noticed that people see their Nook HDs restoring to factory settings after 8 unsuccessful reboots next time you boot after rooting, so possibly there's some extra check somewhere.
Very sneaky on the B&N side, I'd say.

Hm, the 8 failed boot = wipe and restore has been true since the NC, and is valuable because it helps keep the device from getting bricked, also triggerable if the registration token doesn't match BN's reg token. I learned this early on by restoring a backup made before I'd erased and deregistered. I forget where the token lives, in /data/ somewhere.
I'll take a look at this on 2.0.2 this weekend - mine updated before I got ADB working so it restores to 2.0.2 now...
OK, so this approach does work with the 2.0.2 OS, and restarting the device does put it into a boot cycle. Very nasty.
Before I rebooted, I removed the post_boot_hook file and also got rid of the symlink; I'd say BN is doing some kind of inventory of what's in system and driving a reflash based on that.
My guess is it's not a very careful inventory, but it'll certainly be amenable to study now that we can get, at least temporarily, root.
Hm. Interesting -- my ability to mkdir /data/su is now gone after the restore. I wasn't able to do it the first time I tried, either - I suspect that there's something keeping some level of eye on that.
Oh, very uncool - in addition to resetting the system, they wipe personal data in the process. Losing the apps doesn't surprise me much. Losing the books I'd sideloaded surprises me.

Do the new HD & HD+ still allow you boot from the external sd card ?

if you put your books into /system/media, it will back them up to the cloud

Is it possible to push a new recovery with adb after rooting? The 8 failed boot repair is only possible with the stock recovery. But then again you may end up in an endless bootloop without it there to finish it's task. But maybe you can find and delete the trigger flag that starts the process.

stuff is best to be not mentioned. /sarcasm.....

recovery is signed, so it's not super easy to replace it with anything that would run.
The unsigned bootloader trick at the moment requires a boot from sdcard.

shouldn't step 8 & 9 be outside the code block?

verygreen:
I just want to thank you for your all your work on the Nook series. I've been using your "size-agnostic method ..." tools and process to run from the SD card on my Nook Color since you created the method, and now I'm excited to use your work on my new Nook HD+ (just received yesterday) !

just got mine and got an update notification. turned off wifi so it didnt complete.any word if it breaks root ir bootloader?

CWM is now possible too.

Something is interesting, eventhough mine originally got automatically updated to 2.0.2, but after the factory reset, it went back to 2.0.0. But for some weird reason I can't get root.
Maybe this will help, the build number is 2.0.0.1031.lithium01.ovation.rldp.s68403 with the manufactured date 10/22/2012
please compare mine to your.
I also rewrote your code into a batch file. You can double check it I guess.
Code:
@echo off
cls
@echo .
@echo wait for it
@echo .
adb devices
@echo .
@echo if you do not see you device listed above hit ctrl+c and exit the script
@echo then check adb on your PC and device then try again.

so, when you run this, after the final adb shell, what are the permissions on /system/xbin/su?
run su and you should get the root prompt.

I don't get root prompt, su never get copied to /system/xbin/su
here is the list of my finding.
Code:
/data/
-rwxr-xr-x shell shell 167 2012-11-10 05:52 boot_complete_hook.sh
/data/su
-rwxr-xr-x shell shell 586212 2012-11-10 06:07 busybox
-rwxr-xr-x shell shell 22364 2012-11-10 06:07 su
/data/local
lrwxrwxrwx shell shell 2012-11-10 06:20 tmp -> /data/
cat boot_complete_hook.sh
#!/system/bin/sh
/data/su/busybox mount /system -o remount,rw
/data/su/busybox cp /data/su/su /system/xbin/su
chown 0.0 /system/xbin/su
everything is in place and correct, but no dice. either boot_complete_hook.sh didn't get executed or it did but never get launched with root permission.

well, there should be more stuff in the shell file, you miss the final chown line: chmod 06755 /system/xbin/su

It did, I just didn't copy and paste the output correctly. But regardless, since the foulder /system/xbin don't have the su file, this mean as I suspected earlier, either it wasn't executed or lauched w/ root permission.

[Q] Polaroid 8" Tablet PTAB8000 ICS 4.0.3

Ok, so a friend of mine bought 3 of these things from Kohls on Black Friday as Christmas presents for her kids and has asked me to help set them up as kid friendly devices. Unfortunately they don't come with any Gapps installed and I'm having difficulty installing any of them including the Play Store. I'm also running into problems installing simple games like Angry Birds. In fact very few of the APK's that I have backed up from my other Android devices seem to want to install on these tablets. I also can't find any forums on here or anywhere else evening addressing these devices yet. I'm wondering if there's some kind of generic udate.zip I can use for these things that isn't device specific? A little while back I was able to install an update.zip on a Zeki tablet that enabled me to finally install all the Gapps and maximize it's potential. But then again those things come rooted out of the box and the update was Zeki specific, so...
Anyways, please if anyone can help? This could be your chance to be the first to help unlock the potential of these devices.

Rooting PTAB8000
This is NOT my work, it is from mbellot at FreakTab, but it worked great for me.
Rooting is easy, market is nearly as easy. Here is the original thought process.
Here it is, modified the way I have done it (a couple times), broken into logical chunks.
1. C:\ADB> adb shell
2. [email protected]:/ $ mv /data/local/tmp /data/local/tmp.bak
3. [email protected]:/ $ ln -s /data /data/local/tmp
4. [email protected]:/ $ exit
5. C:\ADB> adb reboot
This gives you write access to /data for the next set of steps.
6. C:\ADB> adb wait-for-device
7. C:\ADB> adb shell
8. [email protected]:/ $ echo ro.kernel.qemu=1 >/data/local.prop
9. [email protected]:/ $ exit
10. C:\ADB> adb reboot
This puts you into a "debug" mode of sorts, the LCD will be black after the boot logo comes and goes.
11. C:\ADB> adb wait-for-device
12. C:\ADB> adb remount
remount succeeded
13. C:\ADB> adb push su /system/bin/su
518 KB/s (22364 bytes in 0.042s)
14. C:\ADB> adb shell
15. [email protected]:/ # chown root.shell /system/bin/su
16. [email protected]:/ # chmod 06755 /system/bin/su
17. [email protected]:/ # rm /system/xbin/su
rm failed for /system/xbin/su, No such file or directory
18. 255|[email protected]:/ # ln -s /system/bin/su /system/xbin/su
19. [email protected]:/ # exit
The chown and chmod in steps 15 and 16 are critical to su working properly.
20. C:\ADB> adb push Superuser.apk /system/app/.
3923 KB/s (843503 bytes in 0.209s)
At this point you can install market files. You need to do it before you remove the local.prop file since the PTAB8000 refuses to run adb in root mode or allow remounting. You can use this as a starting point for installing market, but I would suggest you grab the latest ICS gapps and replace the files. Also, market/play is not vending.apk in ICS, its phonesky.apk.
Once you're done with su and market you need to make your tablet boot normal again.
21. C:\ADB> adb shell
22. [email protected]:/ # rm /data/local.prop
23. [email protected]:/ # rm /data/local/tmp
24. [email protected]:/ # mv /data/local/tmp.bak /data/local/tmp
25. [email protected]:/ # exit
26. C:\ADB> adb reboot
Finished.

Thanks.

HD Brian,
I'm going to say thanks because I'm sure everything you just posted is probably going to be very clear to quite a few people that understand all of that. So thank you for helping out. Unfortunately though for me, I got lost. Though I've been tinkering with android and windows mobile devices for about 3 years now, I've actually never done any ADB editing and not sure I fully understand how to do it.
Personally I'm not too concerned about modifying these things too much because they are for someone else's kids, and I've found a way to work around rooting and using Gapps to be able to install the apps they're needing. And before I hand these things back over to be wrapped for Christmas I'm going to make a video showing what I've done to maximize the out of box potential of these things.
But on that note, I'm going to make a request of you if you don't mind. Considering you seem to know how to easily achieve the task, I was wondering if you'd be willing to make and post a Youtube video that takes people through the steps. I know it might be time consuming, but after all we are all here to help each other out. And I'm sure that the people who actually own these devices would really appreciate it. At this point I haven't been able to find any videos on how to mod this tablet yet and the only forums that I've found discussing these things are the one you mentioned and this one here.
So I hope you'll be willing to help other owners out, and I appreciate you taking the time to respond.
Thanks

I had been thinking about reloading the stock rom and doing the root all again as a refresher for myself, but I have never done a YouTube video before. I will try to find the time to do it and them I will post the link here.

For anyone still having issues with rooting and getting the play store on this device I have just made a script to automate the whole process.

Note ADB drivers are required.

Thanks! I was able to run this script, it read the tablet, I asked it to root and install gapps, it said it completed but when the device restarts, I see the polaroid logo twice, then the screen goes black and just sits there forever. I was able to re-install factory and boot it back up so that was good. But didn't know if you had any ideas on what was wrong with my device. I'm using a brand new stock Polaroid PTAB8000 ICS 4.0.3. Windows 7, freshly installed Android Development Kit from today to get my ADB.

Any luck with this script yet? Also, how were you able to flash back to factory?

Wanted to add, got the same black screen so I booted to recovery and did factory reset which got me back to square 1. I install the getjar app store and did a search for gmail. when it came up i downloaded it, and during the installation it also installed the "Google Play" store. I was getting a few errors but after turning sync on and using the store for a bit they all cleared up so far. Now I have google play and gmail apps on the tab.

Sorry about the black screen issue guys there was an issue with the code. I've also completely rewritten the application in c++. All features should work without issues now.
You can download the software here: mediafire [dot] com/?o2864kb92hcc0hb (sorry i can't post links yet, I'll work on getting some posts done...)
1) Download RAR file
2) Extract RAR file
3) Run PolaroidAIO.exe
4) Enable USB debugging and Stay awake
5) Drivers are included in this release if needed
6) Enjoy your fully rooted tablet with the Play Store and Google Services Framework.
If anyone is intrested in the source code let me know and I will post it as well...
Have fun guys!

There was a bug in the old code, same thing happend to mine after i did a factory reset to try and replicate your situation. Try the updated version 1.2 and let me know if u face any simular issues.

Hey I just wanted to point out that you can indeed use root and remount /system. if you have proper root. which my AIO application will test for you as well. Here's what you do to remount /system as r/w:
Code:
C:\dev\adb>adb shell
[email protected]:/ $ su
su
[email protected]:/ # mount -o remount,rw /system
mount -o remount,rw /system
[email protected]:/ # chmod 777 /system
chmod 777 /system
[email protected]:/ # chmod 777 /system/app
chmod 777 /system/app
[email protected]:/ # exit
exit
[email protected]:/ $ exit
exit

I was able to get the play store on with the first upload and then by following a couple of steps from aother tutorial, but I can't seem to get any apps in the Play Store to open or download. I keep getting a "device is not compatible" message. I've tried the DPI play store and also messed around with LCD Density Monitor but haven't had any luck. If someone could help tackle this problem as well as get netflix up and running, I would be extremely grateful. This seems like a pretty awesome tablet, it just needs to be let free.
I feel I should also add, for anyone considering doing this, that once you have the Play Store installed, at least in my experience; if you have it hooked up to a PC via the USB and try to install anything, it goes ape sh** and starts trying to force close and kicks a whole bunch of errors. It doesn't seen to do anything, but it's annoying as hell. I haven't tried it yet with it plugged into the charger, and it doesn't do it nearly as much when you have it unplugged, but it's just another one of those quirks that I'm sure will be fixed in due time.

Sorry about the black screen issue guys there was an issue with the code. I've also completely rewritten the application in c++. All features should work without issues now.
You can download the software here: mediafire [dot] com/?o2864kb92hcc0hb (sorry i can't post links yet, I'll work on getting some posts done...)
1) Download RAR file
2) Extract RAR file
3) Run PolaroidAIO.exe
4) Enable USB debugging and Stay awake
5) Drivers are included in this release if needed
6) Enjoy your fully rooted tablet with the Play Store and Google Services Framework.
If anyone is intrested in the source code let me know and I will post it as well...
Have fun guys!

There was a bug in the old code, same thing happend to mine after i did a factory reset to try and replicate your situation. Try the updated version 1.2 and let me know if u face any simular issues.

Hey I just wanted to point out that you can indeed use root and remount /system. if you have proper root. which my AIO application will test for you as well. Here's what you do to remount /system as r/w:
Code:
C:\dev\adb>adb shell

mount -o remount,rw /system

Just to be sure you may want to run the updated script because there was alot of garbage left behind by 1.0. which 1.2 will clean up.
1) Select "Remove Google Applications and Framework"
2) When done, select "Un-Root Device"
3) Finally select "Root Device and Install Google Applications, and Framework"
This will clean up the garbage left behind by 1.0 and might help with some of your issues.
I am aware that some apps are showing up as un-supported, I'm pretty sure its an issue with build.prop. I'm looking into it right now. Are you having issues with all the apps on the play store? or just some of them like netflix, angry birds, etc? Also can you elaborate on what errors you are getting? I think i need to find an updated version of google services framework, I've noticed when the market upgrades to the play store it will crash quite a few times during the updates, and then gets better but does crash from time to time. Don't hurt functionality but it is very annoying.
If you find any info on any of this please be sure to share. I'll try and get an updated release out tonight that takes care of at least some of these issues... At least we are making progress...

I downloaded the files from location listed above but it my anti virus primped me for a Trojan virus... Is this not a secure release?

This is a secure release, it probably doesn't like all the files embedded into the exe... I can re-upload it un-packed if you like.

No it's ok I thought I would ask. So the big issue is the play store?

Yes, the protected applications do not show up, or if you try to use the web site, and send an app to your device it will say unsupported, I'm going to take a look at my build.prop in a little bit and see if i cant get the full market working. From what I can tell its google blocking the apps because this is a non google supported device. which is why we needed to load the play store in the first place, if you run AIO 1.2 you will at least get all Googles app's working... Gmail, etc. I will have an update out soon to fix the play store issues, and hopefully fix the crashing gapps service...

Okay. I don't have the tablet with me right now, but when I do, I'll redo everything. Also, I was able to get Netflix to work by downloading it from Amazon's App store and everything "seemed" to work. I'll have to try more testing when I get the tablet back. As far as the Play store goes, it just says that it has stopped working and has to close, and when I hit okay, the error goes away but it stays open. I'll get the exact verbatim when it pops up again. Other than that, nice work and hopefully we can work out the kinks.

If the play store is just crashing then i would most definitely recommend using 1.2 to clean things up and reload the playstore, you may even want to go as far as to do a factory reset after you un-install and un-root... Well for some reason build.prop doesn't seem to change anything on the market, I'm downloading an updated gapp for 4.0.3 maybe that will take care of some issues under the hood.

I haven't tried the new version yet since I don't have my laptop with me right now but I'll try it later. To reset back to factory after getting stuck on the black screen follow this sites direction. You will need a micro SD card. southerntelecom dot com / polaroidsupport / firmware /firmware_guide_ptab8000 dot html then download the files for your model and then put them on the SD card and insert the SD card in the tablet. Then to start the factory reset hold down volume down and power at the same time until you see the update screen come up. I believe that is what it said. It should explain it all in the link. If my link won't post since I'm new just Google ptab8000 firmware and click on the link for a southerntelecom firmware site.

Proximity Sensor Bug Fixed, .Screen turns off during call.ISSUE FIXED

Methods that worked for me.
Method 1.
Blow Air it will solve your prob hopefully.
Method 2.
go to samsung code *#0*#. then SENSORS and Read your Proximity sensor values.
<<< DECISION >>>>>
####Calibration isnot needed if ####
.
your phone doesnt vibrate in normal but does so when u physically put your finger on the Sensor.
#### Calibration needed if ####
.
your phone is vibrating in this menu no matter what, you put your finger on the sensor or not
Follow these steps
1. download Android Terminal from store
2. type these commands to calibrate automatically
$ su
# echo 0 > /sys/devices/virtual/sensors/proximity_sensor/prox_cal
# echo 1 > /sys/devices/virtual/sensors/proximity_sensor/prox_cal
Reboot and see if it works.go to *#0*# and check if it continuously vibrating or only does so when you put your finger on the SENSOR.
<<<< IF Continuously Vibrating Follow these steps>>>>
you need to manually put values in ur /efs/prox_cal.it Reads Hexadecimal value. so you have to convert your decimal values into HEX.
##### FIND YOUR Decimal Values and pushing them into /efs/prox_cal ######
Method : finding two values for calibration . offset + normal value.
##.. FINDING OFFSET ######
cat /sys/devices/virtual/sensors/proximity_sensor/prox_cal
note down the values it returns.. mine is 5,64,100.. you only need the 1st value which is 5.
### FINDING NORMAL STATE ######
cat /sys/devices/virtual/sensors/proximity_sensor/state
note down the value if returns. mine is 64
now ADD OFFSET value + Normal Value
5 + 64 = 69
Convert in Hexadecimal which is 45.
NOTE: sometimes normal value is 0, its OK you do you math and convert 1st OFFSET into hex. using lower case for Hex values in steps below.
<<<<<<<<<<< Pushing the value in /efs/prox_cal >>>>>>>>>>>>>>
# echo -en $ '\x45' > /efs/prox_cal
then
# chown system:system /efs/prox_cal
# chmod 644 /efs/prox_cal
# sync
# Reboot
All done. after that go to *#0*# then SENSORS and move your finger on the sensor, yout phone will Vibrate only when you put your finger on the sensors.
Manual method worked for me.
ENJOY.
NOTE: I am not a developer. i was just stuck with this problem for so long so now i found it from "mcelicalderon". who posted this method some where

Wow thanks. Skype totally killed my phone because of this and I thought it was a bug but the manual calibration fixed it. Cheers.

10 million thanks for this!!!, I´d say you were sent by an angel, I was looking for my opperator's stock ROM to flash it and ask for warranty because of this problem and I accidentally found your thread. The manual method worked perfectly.
Now one question: Is it necessary to follow this procedure each time I install a new rom?

Thanks Dear.. it delighted me that it worked for your ..
nope ... i flashed 100 other roms .. and it stays the same .. and sensor works properly.. :

Thank for this. It has fixed my wifes samsung s3. A few things that might help others..
My problem stared when I replaced a cracked screen
The echo 0 & 1 worked, but didn't keep after a reboot
After putting the new calibration value in /efs/prox_cal, I forgot (read 'too lazy') to do the chown and chmod and it was lost when I rebooted. The next time I did the chown & chmod and the value was saved.
For me, after I did the echo 0 & 1, I could see that /efs/prox_cal had been updated (which was then lost on reboot)
I tried doing a echo 0 & 1 (which updated /efs/prox_cal) and then I did the chown & chmod. This permanently saved the values for me.
Summary - If echo'ing 0 & 1 into prox_cal is lost after a reboot, try the following before going to the effort to calculate the calibration value
Code:
$ su
$ echo 0 > /sys/devices/virtual/sensors/proximity_sensor/prox_cal
$ echo 1 > /sys/devices/virtual/sensors/proximity_sensor/prox_cal
$ chown system:system /efs/prox_cal
$ chmod 644 /efs/prox_cal
$ sync
YMMV

Just want to say that just performing these steps has fixed the problem. (which was that the sensor would turn the screen off and then would be stuck at " near possition" until the process using it was terminated and restared e.g a phone call)

I'm still watching on, but looks like it really works... in my case, my values were different and based on it I still had the problem, then I tried input 45 as in OP and it solved. Thank you very much for sharing!

I fixed my sensor by opening my phone and disconnecting the sensor and cleaning it from the inside! But good guide tho.

i changed the digitizer like twice.... then i start to have this issue when calling.... and i couldn't end the call because the screen won't turn on.... blowing air amazingly worked for me

'Restore' your display

I bring to you another script, courtesy of Amazon. This one might not suit a lot of you, so be prepared. Like most of the tricks we've tried this past week or so, even resetting the reset, may not be to your liking and can only be reverted via factory reset.
Titled 'Display,' it toggles at least three modes. i didn't quite understand them so I went ahead and ran the script in Terminal Emulator. This was also in /system/bin.
Code:
[email protected]:/ $ cd /sdcard
[email protected]:/sdcard $ sh display.sh
usage: display [<device name>|reset]
<device name>: the name of device (e.g. apollo/thor/soho) reset: setting orignal value of display for this device.
It changes size, density and values. The last one sets it back to "original value." I don't have a before shot, because I wasn't expecting anything. Cleaner, brighter, crisper and in my opinion, more HD.
Edit: the picture does no justice unfortunately.

1. Go to /system/bin
2. Locate file: display
3. Rename to display.sh
4. Copy to internal storage
5. I used Terminal Emulator
Code:
$ sh /sdcard/display.sh
Enter the command that will "reset to original" and you get sharper screen, brighter and more vibrant. Your text may look a bit smaller and folders on home also. I think this is the HD the tablet was missing.

Display Configuration:
Code:
/system/etc/display_conf
Code:
# Please add new device using the same format.
# The comments begin with "#".
device=apollo, size=1600x2560, density=320
device=thor, size=1200x1920, density=320
device=soho, size=800x1280, density=240
Followed by...
Code:
/system/bin/display
Code:
[email protected]:/ $ cd /sdcard
[email protected]:/sdcard $ sh display.sh
usage: display [<device name>|reset]
<device name>: the name of device (e.g. apollo/thor/soho) reset: setting orignal value of display for this device.

Hi
Is the actual command something like ./display.sh hostname
I ran the script with the above but said permission denied.

Go to system/bin and locate display file. Copy it and paste to internal storage then rename to display.sh. Open ADB, get a shell and type:
Code:
$ cd /sdcard
$ sh display.sh
$ display reset
If your screen is already at its properly set stage, it won't change, but you shouldn't get an error. You would see something like:
Code:
$ wm change ...
Also in system/bin is the script 'wm' which you can use to manually change your DPI to whatever you want. Perform the same steps above for the wm file.
Code:
$ cd /sdcard
$ sh wm.sh
You can use this app to monitor the changes you make to your DPI in real time. Just make sure to note the starting DPI so you can go back to it.

Thanks DragonFire1024. i cannot tell the different after resetting the display though.
