Fix WiFi Channel 12-13

You can fix wifi channel 12-13 support by setting the wifi_country_code to EU.
You need a rooted device and sqlite3 to fix (attached).
Unpack the attached zip and run fix_wifichannel_EU.bat (Windows only)
or with linux:
Code:
adb shell
su
mount -o rw,remount /dev/block/mmcblk0p3 /system
exit
adb push bin\sqlite3 /system/bin
adb shell
su
chmod 6755 /system/bin/sqlite3
sqlite3 /data/data/com.android.providers.settings/databases/settings.db "INSERT INTO secure (name, value) VALUES ('wifi_country_code', 'EU');"
reboot

Ohhhh it's good to see you here in the Iconia section!
I used to be a user of your great Desire Kernels/roms.
Hope to see some work from you soon.

so you got this tablet, richard =P Wonder when we will be able to start playing with custom rom =)
Btw, I notice that a huge amount of RAM is consumed and the maximum amount of RAM freed I have ever got is 440MB. Do you know what happened to the rest?

The rest of the ram is reserved for video on boot.

I thought so, but don't you think that is too much out of 1GB ram? I found the device is laggy if ram goes under 350MB. Hope modded kernel can help optimize ram.

Nicely done! It works. Yea it is good to see you here' meaning we have somebody who knows a thing or two about android development.

Fix worked!
For some strange reason adb remount command didn't worked and adb wasn't able to push sqlite3 file to /system/bin even after remounting /system rw from the device itself. I had to push it to sdcard and then move it to /system/bin.
By the way, channel 13 is working fine now.
Thx

Hi Richard,
It's good to see such a great dev interested in the A500 (I have a Desire). <vbg>
EDIT: I can confirm that this works!
I cannot remount /system, either via ADB nor via a shell (on the device itself). In both cases, I get...
Code:
mount -o rw,remount /dev/block/mmcblk0p3 /system
mount: Operation not permitted
[Edit: worked with a terminal, but forgot to SU first, and I was typing mmcblkop3, not mmcblk0p3 !!]
I tried to be clever (NB: I don't have a SD card installed):
Code:
adb shell mount -rw /dev/block/mmcblk0p3 /mnt/external_sd
Usage: mount [-r] [-w] [-o options] [-t type] device directory
That's the extent of my *nix skills...
Any ideas?

Try su before the mount command.
Edited the procedure in the first post so try that (should work now).

For the beginners (like me): I noticed that /system was set back to read-only on reboot...

Works brilliantly. Thanks.

thx - but I trust editing the build.prop in Root Explorer should also do the job for those who don't want to mess with adb and commands.

hi
can anyone tell me whats this fix for?
is it going to make wifi receiver even better?
thx..

ro.wifi.country=EU
and reboot.

i have this message:
'Unable to detect a device over adb'
I've connected my nexus S via usb cable, i've tryed with the usb usb storage on an off, and i get the same message.
I'm using windows / x64.

Here you go :http://tinyurl.com/4476rrj

I already have openVPN working in froyo and gingerbread on a i7500, see here: androidforums.com/samsung-i7500/330288-openvpn-gaosp-beta3-i7500.html
Basically you need to copy the key files to a folder, execute some commands from the terminal emulator, and use the "openvpn settings" app to enable it.
Unfortunately, the commands have to be modified for the O1 gingerbread rom.
Anyone help?

[Q] changing hostname

Hi,
I'm new to Android, so please bear with me. I just recently picked up a Nexus 4 to play with. It came with 4.2 on it, and I have done the OTA updates to 4.3 and then 4.4. I decided to root the device and followed the instructions here. That all seems to work OK and I can get root using adb.
The first thing I tried to do next was change the hostname from android-something to a hostname that I could remember. I did a bunch of searching here and found the following commands suggested:
Code:
getprop net.hostname
setprop net.hostname
If I run these commands, the hostname changes. The problem is once I reboot, the name is back to what it was originally. I even tried remounting /system as rw, as I saw in some other post, and running the command again like this:
Code:
mount -o remount,rw -t ext4 /dev/block/mmcblk0p1 /system
setprop net.hostname NEWNAME
mount -o remount,ro -t ext4 /dev/block/mmcblk0p1 /system
I tried rebooting after that and the name change still doesn't stick. What am I doing wrong?

It shouldn't be changed

Thanks for the reply. I had seen that there were apps for this, but I figured it would work on the cli if an app could do it.
Why do you say it shouldn't be changed? I've never had a device that you weren't supposed to change the name of.

I figured that was gonna be an issue.
There are so many variants when it comes to device / busybox, I tried to get around that by including my own binary but fail on my part i guess...
Anyways.

I rewrite with mke2fs -F $IMGLOC/$IMGNAME this working well.
But another problem with debootstrap. See attachment. So it's end of testing, isn't it?

Sry, not working, but I deleted line with checking architecture and I got new error. See attachment.
EDIT:
I use:
sh install-or-mount -i -n linux.img -m /data/local/chroot -l /data/local -o precise -0
Rewrited mk2fs line in install-or-mount file to: mke2fs -F $IMGLOC/$IMGNAME
Deleted if [ -z "$ARCH" ] || [ -z "$HOST_OS" ]; then error 1 WHATARCH "Couldn't work out current architecture" fi line in deboostrap file
I think if I deleted this line, chroot not mounted correctly and bootstrap can't continue. So we need figure out, how fix architecture error.

All the errors you are getting I did get at one point, I forgot how I fixed them, cause I was working on another project..
Ill do some testing, as I am working on the code right now.
Ill post when I find a solution to those..
Also before continuing I wanted to just let you know.
the debootstrap requires 'ar' archiver which I do not believe comes with CM.
busybox ar
That is why I included my own version.
I may have some work arounds tho so give me a few..

You need root, and an android device.
No OTG cables..
It build's a chroot image on the device, with android running in the background.
You can run X windows (only LXDE currently because it is lightwieght) on the device and then vnc into it from anywhere, even a desktop...
There are other tools out there for this however, they require you to download the images. Which are usually between 1gig - 4gigs.
Instead of downloading the images, this creates the image and only downloads approximately 200megs for the packages.

Thanks for the explanation, sounds great

Yea, crap, that was my bad, I should check where the system busybox is installed. It should default to /system/xbin
But some roms I guess put it in /system/sbin ? Possibly a typo on the rom developers part? LOL
Anyways, I will add code to correct this.
EDIT: How did you fix image 2?, as it should stop at the error in image type every time.
At any rate, image 2 error is because it can't find sh. in the install-or-mount/bin directory type this..
ls -l bin/
Make sure sh is symlinked to /system/bin/sh or /system/xbin/busybox if not that is causing the error in picture 2
it should look like this...
ls -l bin/
sh sh -> /system/xbin/busybox
If you don't see that do the following:
cd /data/local/install-or-mount
busybox touch bin-configs/sh
rm -rf .bin-configs-done
if you have something like that it should be ok, however to be safe since you moved you your busybox
from inside install-or-mount
rm -rf .bin-configs-done
Yes there is a DOT in front of bin-configs-done

I receive a permission denied error with debootstrap as well
Edit: crap I didn't see all the replies up there

Will it works on my armv7 single core tablet?

I fix it other way:
mount -o remount,rw /system
cp busybox /sbin /system/xbin
mount -o remount,ro /system
I hope that commands are fine.
I has no solution for fetch Release error, yet. I tried rewrite URL, but unsussesful.

[Stock][Kernel-Module][KK.283][LP.454] NFS

Hey Guys,
Just wanted to share with you the NFS-Module I build today.
Maybe someone can use it.
You can copy the Modules wherever you want and then let it load automatically by an APP.
For example with Mount Manager
Or you can load them manually in this order by:
Code:
su
insmod /path/to/module/sunrpc.ko
insmod /path/to/module/lockd.ko
insmod /path/to/module/auth_rpcgss.ko
insmod /path/to/module/nfs.ko
Mounting can be done in Terminal, with "busybox mount". Normal mount seems not to work:
Code:
su
busybox mount -t nfs -o hard,intr,nolock,sync,vers=3,exec 192.168.1.1:/path/to/share /path/to/mountpoint
Unfortunately, since JB Android doesn't make mounts made by root visible for other users.
So even if you mount via Terminal or with Mount Manager, you won't see anything as normal user.
You can see them only as root.
If you want to mount shares for normal user, do the following:
Code:
su -c setenforce 0 && su --mount-master -c busybox mount -t nfs -o hard,intr,nolock,sync,vers=3,exec 192.168.1.1:/path/to/share /path/to/mountpoint
-
