anybody know how to get ad-hoc wifi to work on the rooted legend?

Hi all,
trying to get my feet wet with some android hacking and thought getting my AR.Drone to work with my legend would be a good start. It requires connecting to the ad-hoc network created by the drone. The normal way is to edit /system/etc/wifi/tiwlan.ini as described e.g. here: projects.ardrone.org/boards/1/topics/show/1098 but /system doesn't seem writable even though I have root. I then found this app for the desire: code.google.com/p/desire-adhoc/ but the legend has a different wifi chip, so it didn't work. Attempting to reproduce what that app does I did
$ adb shell
# su -c 'insmod /system/lib/modules/tiwlan_drv.ko'
insmod: init_module '/system/lib/modules/tiwlan_drv.ko' failed (No such file or directory)
even though that file definitely exists. Am I missing something here, or is that part of the annoying restrictions still present even on the rooted legend? Ad-hoc wifi must be possible somehow, the wifi-tether guys managed to get it to work. Unfortunately their code is a bit over my head. Any pointers?
thanks

Do it from recovery mode. We don't have access to /system in normal usage of phone (you get used to it).

okay, I guess I have to learn how to bake my own update.zip.
still curious though, why am I getting "no such file or directory" if it's clearly there (and a similar method seems to work on the desire)?
I also tried this:
forum.xda-developers.com/showthread.php?t=754961&highlight=legend
Which is a quite cleverly hacked wpa_supplicant, but that resulted in no wifi at all any more, even though the patched supplicant is officially the same version. strange.
any clue how the wifi-tether guys do it?

No, those command work. Boot your phone to recovery mode, then mount the /system partition from the ClockworkMOD menu. then you can execute your commands, they should do it.
Also, questions like this shouldn't really be in the development section. Just so you know.

You got it all wrong guys... first you dont need to su -c as you already are root. Second... you need to load sdio.ko prior to tiwlan_drv.ko. And no we do not perform these in recovery mode

I thought he was editing files... Oh well, I'll read more carefully in future. Sorry guys.
EDIT:
Yeah, look:
The normal way is to edit /system/etc/wifi/tiwlan.ini as described e.g. here: projects.ardrone.org/boards/1/topics/show/1098 but /system doesn't seem writable even though I have root.

So he could edit from recovery mode. But, I was still an idiot, I said to do the insmod things from recovery. I am very sorry for wasting time here, I'll learn to read carefully and give proper answers.
Sorry

aaaahhh, that got me a bit further thanks! very confusing error message...
so module loading works now, but the phone just reboots a few seconds after I set
"iwconfig tiwlan0 mode ad-hoc"
any further advice?
Also I guess the confusion was my own fault since I rolled three different ways of doing one thing into the same post...

Oh man, I've said all the wrong things today. I'm so sorry. I'll just leave this thread now.

Yes. Loading modules just isn't enough in our case. You need to load firmware too before you bring interface up otherwise your system will reboot
Check Gratiend ROM thread or look into init.legend.rc for hints on firmware loading...

thanks. found this
/system/bin/tiwlan_loader \
-f /system/etc/wifi/Fw1273_CHIP.bin -e /proc/calibration \
-i /system/etc/wifi/tiwlan.ini
after googling init.legend.rc. doesn't seem to make a difference though. also tried using tiwlan.ini from the wifi tether guys, but no luck. device still reboots after setting ad-hoc mode. I guess I give up, there's no-one answering to my question on the wifi-tether google group either. i guess just because it's open source doesn't mean it's for the uninitiated...

Try sleep for 1 or 2 seconds after you load firmware, then bring interface up or start wpa_supplicant.
I you are using patched wpa_supplicant I guess you will have one more obstacle. It supports only wext aware devices and I guess our driver is not wext aware...

I solved the problem by installing Cyanogenmod (all other tries failed)

I enter the commands by hand, so there's already a delay in between. And I'm doing this by hand precisely because the patched supplicant didn't work on the legend. I guess now I know why. Thanks for all the advice though.

I had a CM6 nightly installed and toyed around with it a bit, but I actually use my FM radio (I know, barely anyone else does...) so I need to use a HTC ROM. liked the CM6 in a lot of other respects though. still out of the question for now.
Also I would eventually like to contribute whatever comes out of this to a proper AR.drone app that requires root and nothing else.

[Q] solving keybord freeze on honeycomb froyo v3

I have to open a new thread here because I can't still post in the android section, by the way I've tried to follow the instruction found in this post for solve the keyboard freezing problem but I when I launch the script it says that he can't find the 2 files it have to launch, and opening the folder by the terminal or by my ubuntu I can't found the 2 files
/lib/modules/microp-ksc.ko
/lib/modules/microp-keypad.ko
anyone knows why?
a member wrote on the same post that he had the same problem, so he have deleted some files and have run the new kernel...how can I launch the device with another kernel?
thank you

Hi,
answer is easy (well, for those who looked behind the scenes), at boot, the system checks if the kernel-modules on the sdcard are different from the installed in /lib/modules ... and due to the fact that the kernel version is the same (just with the keypad drivers optional as modules), the unpacking of the tar.gz-archive is skipped.
You have two options now, use the 'Terminal Emulator' and do a:
su
rm /lib/modules/*
and reboot your phone, or copy the two modules from the tar.gz in ubuntu.
Ciao
Kurt

I have tried the first before opening this thread without any result, now I'm retrying

ehm...now the script runs...but I can't use the onscreen keyboard and everytime I enter an app the screen rotates...is it normal?
and if I press camera button it doesn't return to the home

Hm, rotating the screen is not normal ... just if he thinks you pulled out the 'real' keyboad.
I think, the camera button of Honeycomb froyo is prepared for camera usage ;-).

Hm, perhaps, best solution at the moment would be, to run the unload-load-script when the phone is waking up from sleep mode. So, when keypad is lost, the user can send to sleep with the power button an immediately switch it on again ... and additionally, the script can run when a call comes in ... don't know if these events can get picked up and the event-handlers can be changed, just thinking ...

[Q] ADB Issue - device offline

A couple of days ago I flashed Eclipse v2.0, wanting to change my phone up a bit I had been on shift3r for a few weeks. Anyways, just now I was trying to copy some modules into my /system/lib/modules to overclock my device and was having issues copying within my phone. So I tried to use an adb shell to do so, but I keep getting the output of the device being offline, this is what I'm getting:
-NV57H:~$ adb devices
List of devices attached
0A3BAF200C014015 offline
And I have done a search, where some people were having trouble using certain cords, mainly with Samsung devices, and switched cords with success. This does not apply in this situation as I have used adb many times with the cord I'm using, and also I did try to switch cords anyways. Also the only other thing I saw was a situation involving driver installation and re-installation creating problems. As I am on Lubuntu, and not Windows, this does not apply to the situation because I have neither installed or re-installed drivers. My adb is setup properly because I have been using this computer for a couple weeks now and it was working previously. Any ideas on anything that could have happened? or maybe I should switch ROMs?
additionally: on my file manager, in the address bar for my device when it is plugged up, it is seeming odd to me, this is now what the address is showing for my device's sdcard:
gphoto2://[usb:002,007]/

I think I might have messed something up on my Bionic. If you read the first post I was saying how I tried adb on the same computer I've been using, AFTER flashing Liberty. Well I've gotten rid of Liberty and went back to SHIFT3R to try to fix the problem, and my problem is still looming. I have tried on Lubuntu and Windows, and my girlfriend's Incredible 2 works on both of the OS's with the same cables I'm using as well. I remember the other day when I was flashing Liberty, I had to mount my USB while in recovery to move the file onto my SDCARD because it had vanished once I tried looking for it to flash it. I remember when I tried to eject my phone from my computer (lubuntu), it said that it was busy and could not unmount the phone, after the file transfer screen went away as well. And then I waited a few minutes and tried again, it said the same thing, but I unplugged the cable anyways and unmounted USB in recovery. The file flashed fine so I know it was not still transferring the zip file. If anyone knows what I may have done or what I may be able to do to fix this let me know. I just wanted to update the thread with my most recent trials and errors in fixing it. Thanks to anyone who can guide me. I have never had issues with adb before.

O man i really hope someone can help us with this issue.
I have the same problem..
I am trying to use the path saver, and it keeps telling me device offline.
RSD lite won't even recognize it.
HELP!!!

Me too
I had the same problem... I wanted to upgrade the radio on my Bionic to the .901 load... I could not get adb to see my device.
Using Windows 7 64 bit (Ultimate).
RSD Lite would not recognize device either.
Decided "Screw it", I'll just go back to my nandroid backup... which didn't work either.... soooo... here I am.... stuck.
Off to google I went... I don't know which of these fixed it, but it is working now... here is what I did.
Found a thread that stated "run your commands from the 'C:\platform-tools' directory... so I took all of the files from the "Bionic Path Saver 1" and copied and pasted them into this directory.
Secondly, instead of just double clicking the upgrade batch file (runmebbb.bat) like I was before, I opened a DOS command shell -IN ADMINISTRATOR MODE- and ran the batch file from there.
It immediately kicked off and I was off and running.
For those of you that don't know what I am talking about, I was upgrading... using instructions from this thread:
http://forum.xda-developers.com/showthread.php?t=1433783
I hope this helps... it bugged the crap out of me... but the feeling of relief certainly makes up for it.

Well the thing is it doesn't work on windows or Linux with my bionic. I've tried various Android devices that I own and all of them work on both of my operating systems except for my bionic

Same issu
I just installed Eclipse 2.2 on my Bionic and now i am getting the same issue. Has anyone found an answer or a fix for this? Also, does the .902 patch have anything to do with it? Any help is greatly appreciated.

Once i had this problem the only way i fixed this was by using RSDLite to flash a FXZ. Changing ROMs didnt work, nothing worked but that. It wont affect RSD reading the phone in AP Fastboot mode. Just make sure you install moto drivers and have the newest version of RSD Lite. That worked for me, now I have my adb back

Are you using Safestrap recovery? If so I think that may be the issue.

Try downloading "ADB Over Wifi" from the market.
Then "adb connect iport"
The widget should show you ip/port when you activate it.

Bionic 2.2 Eclipse adb device offline
Hello,
I am having the same problem. I'm using Safestrap. Droid Bionic on the 902 update, rooted with Eclipse 2.2. Everything is fine except adb shows my device as offline. I've looked on this forum and searched and it's not the cable. Also ADB over WIFI does not work. I'm not sure why it has the result it does there should not be 2 ports...
COMMAND: adb connect 10.0.2.2:5555
RESULT: unable to connect to 10.0.2.2:5555:5555

First of all, it automatically adds 5555 into your address so instead use
Adb connect 10.0.2.2 or whatever your ip is. And as far as not showing your device with a USB cord, try various other cables. I have over ten cables and maybe two work with my bionic. I urge you to use as many as possible before my next recommendation. This problem screwed with me for a couple months and finally i booted into fastboot mode and FXZd my phone. I booted my phone up after that and adb worked perfect. I don't know what causes this.

Eventually I discovered why adb wasn't working. Apparently there was no adb daemon running. I came across this in a different thread awhile back. Once I copied it to my phone's /sbin/ directory (there was a link to the file in this post http://forum.xda-developers.com/showthread.php?t=974824) and ran adbd from a terminal I could use logcat. However it was removed everytime the phone cycles power so only a temporary fix. I was considering trying another rom instead of eclipse 2.2. It was also buggy in that when I tried to do an adb install it broke terminated the daemon.

If you're using linux I always do "sudo adb start-server"

[Q] Q: touchscreen qtouch driver Q

Is it possible to power up the touchscreen via a device driver ioctl?
I am trying to read from /dev/input/by-id/touchscreen during "on post-fs"
in init.rc
EVIOCGNAME gives me "qtouch-obp-ts"
just not returning any events.
the read() simply blocks.
do I need to add a write to a /sys/devices...power... file?
I am clueless.
everything works when run from prompt.
Any pointers are appreciated

solved
in init.rc
on post-fs
start touch
exec my_app
service touch /system/bin/touchpad
class pre-zygote...
I did not have to do this on my nexus one running the same mods.
I still dont know what or why, I still think it needed a wake up.
Maybe there is a cleaner way to start the touchscreen

you need to run "touchpad" to upload the firmware to the touchscreen, otherwise it won't do anything.

Proximity sensor error

Hello,
I have been using XZ for two years now with no problems and started flashing about a year ago.
Now, my first problem came when I wanted to connect my phone with a bluetooth headset. It works fine until I turned off the screen and placed it into my pocket. After investigating the possible issues, it seems to come from the proximity sensor.
First tried to install another ROM, as maybe the error came from there but it was to no use.
Then I tried dialing *#*#757....... the sensor will be off, if I block it, it will say on, but when I unblock it it stilll says "on".
So I went to try to turn off the proximity sensor completely, as every apk i tried didn't fix the error.
The other fix I found was an Xposed framework.
I followed the instructions of installing ExistenZ_Y but when I tried to flash the ROM it said "can't mount /system" and had to go through recovery to flash a stock ROM. The problem is that even now, when I enter TWRP and try to flash the xposed-v78-sdk22-arm it still says it can't mount the system. I tried going to the terminal and typing "mount -o rw,remount /system" but to no avail, it won't mount the system as rw.
So here I come, after searching every thread I could find, to know if someone could help me in any way.
Many thanks in advance

add the line:
gsm.proximity.enable=false
to the end of the file build.prop located in /system, reboot, and the sensor will be disabled.

Tried some that use light sensor (which is working) instead of proximity sensor but still no luck...
How hard can it be to disable one sensor?
PS: I know, found it during a forum search so no need to open a new one

Dont know man, are you sure you entered the command exactly as i wrote?
If yes try to find the command inside the build prop on your own and edit the true part to false
eg: gsm.proximity.enable=true --> gsm.proximity.enable=false

Yes, i added this "gsm.proximity.enable=false"
without quotes at the end of build.prop file. Is that a universal command or xperia z specific ?

That is also the only way I found. The easiest way is to go through adb. You go 'adb pull /system/build.prop' modify it on your computer then go 'adb push build.prop /system/'. It worked for me. It didn't solve every problem but sure did help a lot!
If that does not work, maybe it isn't your proximity sensor? I know there are apps that can "write" the info that your proximity sensor info is either 0 or 1 (or in between), but that didn't work for me, maybe with you it will

What rom are you using? I edited build.prop file from phone and saved successfully. I tried some apps but no luck. I wonder if that command maybe is different in nougat roms
