Anything good?

I have the same file, with a different hex key of course. I doubt if this is the answer to our bootloader dilemma. But I applaud you're exuberance. Keep up the good work. I am surprised to see so little activity in this thread too. I figured someone with some experience would be speaking up to debunk or confirm the finding as a probable highway to ROM flashing heaven. Did you see what I did there? I totally showed my age.

That key is specific to your machine and there is a brother key in the machine(low level) that meet in the middle and basically make a new key that is checked and verfied. Kinda how HDMI keys work. Sorry to deflate your bubble but one key to a two key lock still won't open the door.

Cyanogenmod: Openvpn error:Cannot load private key file

Tried to activate openvpn that comes wiht Cyanogenmod version 4.2.5. After running openvpn --config openvpn.conf I got the following error:
Cannot load private key file private.key.pem: error:0906A068EM routinesEM_do_header:bad password read: error:140B0009:SSL routines:SSL_CTX_use_PrivateKey_fileEM lib
Error: private key password verification failed
Exiting
What Im doing wrong?
In my opinion you try to use the private key which is protected by password. One of the ways to cope with the problem is to get rid of the password. You can do that by using the following command:
openssl rsa -in your_password_protected.key -out your_passwordless.key

IPv6 Privacy Extensions

I just tested Privacy Extensions successfully under Virtuous 3.2.0 using the following command:
sysctl -w net.ipv6.conf.default.use_tempaddr=2
However I'd like to make the change permanent. Would it be better to create /etc/sysctl.conf which currently does not exist on my device, or add it to the /sys/module/ipv6/parameters directory? I tried the later, but was unable to create the file. Any ideas?
# pwd
/sys/module/ipv6/parameters
# echo 2 > use_tempaddr
cannot create use_tempaddr: directory nonexistent
code.google.com/p/android/issues/detail?id=14013
I'm on a Galaxy S but it doesn't matter.
I used the command from there https://bugs.launchpad.net/ubuntu/+source/procps/+bug/176125
on adb:" echo 2 >/proc/sys/net/ipv6/conf/all/use_tempaddr" but i get the erro:
"cannot create /proc/sys/net/ipv6/conf/all/use_tempaddr: directory nonexistent"
I made a textfile in windows and named it "use_tempaddr" and wrote "2" in the textfile. Removed the *.txt extension and copied it to /mnt/sdcard on my GalaxyS.
Then I made "busybox cp /mnt/sdcard/use_tempaddr /proc/sys/net/ipv6/conf/all/use_tempaddr" but I get the error: "cp: can't create '/proc/sys/net/ipv6/conf/all/use_tempaddr': No such file or directory"
Pls, help me how to get that file working.
You could use a sysctl.conf in /system/etc, just follow the steps here:

Very simple
failed to copy 'sysctl.conf' to '/system/etc/sysctl.conf': Permission denied
Why?
Can I do "adb shell" instead, then "su" to have access? But what is the command from inside adb shell instead of adb push?
EDIT: I pushed it to /mnt/sdcard but I can't copy it to /system/etc with Astro, the paste option is grayed out
EDIT2: Ok it worked. I downloaded "super manager" from the android market, and activated the root (rights) function of super manager.
Edit3: But going to for example http://test-ipv6.com on my Android device does show the MAC in the ipv6 address. So it didn't work
EDIT4: Another thing is, the Android Browser of Android 2.2 seems to only support ipv4

You need root to modify the system partition.
Did you "sysctl -p" after the transfer? If not, open a terminal on your phone (or adb, whichever you prefer), and type that. The command should output the contents of your sysctl.conf
If that is successful, reboot, then try the website again.
If I enter sysctl -p it says sysctl:not found
if I enter sysctl.conf -p it says sysctl.conf: not found
But when I cd to /system/etc and do "ls" i can see the sysctl.conf file is present.
btw: I'm rooted.

Try:
Code:
busybox sysctl -p
Usually the update-script used to install roms will symlink this for you, but in this case, it's just one extra word lol.
Code:
$ export PATH=/data/local/bin:$PATH
$su
# busybox sysctl -p
sysctl: error: 'net.ipv6.conf.all.use_tempaddr' is an unknown key

hm.....
That's the extent of my knowledge sorry to say. Not too familiar with all of this
I hope someone can solve your issue!
Just for a sanity check, you could try looking at what is allowable in the context of your dinc: // I only looked at eth0, you can look at whatever you like using enough terms to get you into the neighborhood.
(from adb)

-- I could echo 1 into the /proc FS spot you were trying to, as well as setting tempaddr=2. I am just guessing that some of the kernels aren't using built in ipv6, so maybe you've got to load the module? "modprobe ipv6"?
I'm also guessing you've tested something easy like "# ping6 -c 4 ::1" just to be sure ipv6 is alive at all.
Just some thoughts - Hashi
ping6 does show that:
Code:
$ export PATH=/data/local/bin:$PATH
$su
# ping6 -c 4 ::1
ping6: not found
# busybox ping6 -c 4 ::1
PING ::1 (::1): 56 data bytes
64 bytes from ::1: seq=0 ttl=64 time=0.191 ms
64 bytes from ::1: seq=1 ttl=64 time=0.924 ms
64 bytes from ::1: seq=2 ttl=64 time=0.968 ms
64 bytes from ::1: seq=3 ttl=64 time=0.198 ms
--- ::1 ping statistics ---
4 packets transmitted, 4 packets received, 0% packet loss
round-trip min/avg/max = 0.191/0.570/0.968 ms
#
grep doesn't exist on the phone:
Code:
export PATH=/data/local/bin:$PATH
$ $su
# busybox sysctl -a | grep "net.ipv6.conf"
grep: not found
sysctl: error reading key 'net.ipv4.route.flush': Permission denied
sysctl: error reading key 'net.ipv6.route.flush': Permission denied
#
And modprobe ipv6 gives:
Code:
export PATH=/system/xbin:$PATH
$ $busybox modprobe ipv6
modprobe: chdir(2.6.32.9): No such file or directory
$
EDIT: "lsmod" doesn't show ipv6
and "insmod ipv6" says "can't open 'ipv6'"
Just a couple things since I've got to run now:
1) No grep on phone: I think it's just another bit of busybox. If you type in busybox and <enter>, then you should see a huge list of verbs / cmds, and you can use "busybox" <verb> (or for grep busybox grep) instead of grep.
2) modprobe ipv6 fails:: I hadn't really studied android much yet, so now I see that ipv6 is most often compiled into the kernel, not a module, so my mistake. It is unlikely to be module except on some early kernel or if someone really wanted it to be.
3) ping6 ::1 returns, is a good, but very embryonic good sign.
4) What are you after? Stateless configuration (DHCP for IPv6 only unique?). Have you had IPv6 working after any fashion (say with a "2001::xxxx:yyyy::z" homebrewed unique address working at all yet? Another thing: Are you behind some IPv6 unfriendly firewall or are you using 3g? If you're on wifi and say, behind an ATT UVerse setup, you are going to have use 6to4 tunnel to get anywhere. (hey, what's another 30 ms? )
--- I'm an IPv6 fan, but only really know configuring it on Cisco routers and true linux boxes thus far. -----
If you're in what maybe is the best of worlds on wifi over a dd-wrt setup, then try to configure an IPv6 tunnel on the firewall on the Outside and see if you can hit that with IPv6. Gotta start somewhere.

I use a AVM Fritzbox 7240 with freetz image.
My ISP doesn't use IPv6 yet but the fritzbox router automatically negotiates if 6to4 is necessary. And because my ISP still has no ipv6 the router uses 6to4.
Another setting in the router config is, that the router addresses 'unique local addresses' to the network device as far as no ipv6 connection is present.
That setting can be changed too.
I'm not a professional network administrator, but I wanted to test ipv6 for the router. And I want to use the privacy extensions on android, because without them the MAC is shown on for example www.test-ipv6.com. Ipv6 does work on android but without privacy extensions at default.
Ah yes, I connect my android device via wifi to the router.
So, if ipv6 is built into the kernel, is there a via to set the use_tempaddr setting? Maybe via a file like rc.custom or how these files are called that load things at boot up.

OK: It sounds like you made a lot more progress than me on the droid if you got it working with any outside site with IPv6. One thing I notice is that although it "appears" I can set use_tempaddr, I then realized that no matter what I type in, it is usually echoed back to me on the command line, so that I have no idea if it was really set. I'm too new to the Dinc to know what it'll do and won't re ipv6.
It turns out I wasn't setting it using sysctl, but I was able to echo 2 > /proc/*/.../use_tempaddr, and that would show up in a 'cat /proc/*' statement. I don't think it actually is working on my ROM or that I haven't yet figured out how to transform the linux statements I'm comfortable with into the watered down droid busybox equivalents. I'm really not seeing much indication other than a few little hopeful things, that ipv6 is fully enough supported on my rev of software to get anywhere.
However, now I'm pretty interested in this and will be working on an ipv6 setup (just got an actual /48 block at work) so will be keeping this in mind.
I'm curious now to know what series of statements you used to get far enough to hit www.test-ipv6.com with ping6? (or did I get that wrong?)
There is a bug filed in the google codebase that implies that ipv6 just isn't working yet, but it looks fairly old. It may be pre-2.2. It is an enhancement request that is still alive and asking for ipv6 support in android, so I'm really interested in what you did before to get it working.
By the way, my results from test-ipv6.com are pretty bleak. 10/10 for ipv4 and 0/14 (I'm forgetting the exact numbers). That was after a lot of setup and attempting to do this the way I'd do a linux box. I do believe it's in the kernel, and sysctl -a seems to bear that out.
I did manage to figure out how to make a dinc kernel tonight, so I can get a better look now at the ipv6.c code and make sure it's in the config. This little linux box is really confusing me right now
Thanks -- Hashi
I didn't do much.
I have android 2.2 which already supports ipv6 but no privacy extensions.
ipv6 worked from the start.
Ipv6 does show me a 7/10 on my win7 pc.
But with my galaxy S android device it shows 0 or 2 (I don't remember)
I think the installed browser of android 2.2 doesn't support ipv6 yet.
I have made screenshots to compare ipv6 on win7 and on the android device via wifi.
Do you think the results for my android device on test.ipv6.com appear like that, because the browser doesn't show ipv6 sites, or do the results mean that I have an ipv6 address through 6to4 but my android device doesn't accept ipv6 yet?

I'll look around for the write-up(s) I found over the last day or two about various androids and ipv6, and they'll perhaps answer some of your questions, like the browser. This is the gist of what I got from reading.
Some 2.2+ androids support (marginally) the ipv6 stack, tunneled AND dual-stack. A couple people can get 'outside' using ipv6, and a couple more can 'browse' ipv6-only websites. The browser isn't the problem. At some low level on my Incredible, the stack doesn't "see" ipv6 addresses as "valid". I think that means it just has some holes left in it. You've got a 'newer' device (Samsung), so this may have been improved.
My scores are 10/10, ipv4, and 0/24? ipv6, and from a 0 score there's nothing it can tell you of use. It just doesn't work. Yours looks very promising.
One thing I'm wondering about is whether I've got a version of busybox that is sadly lacking in ipv6 functionality. All the network applets come out of that single executable. I've got busybox 1.16.0, and am curious which you've got. I could change busybox's version easily, in fact you can go to busybox.net, get source, fix it up, use toolchains and build it.
Also, life is easier if you just install it (./busybox --install .) since it'll make a symlink for each function in whatever folder it was in (like /system/xbin is pretty empty and on my path).
Let us know when you get it running. I'll do the same. Another thing missing in mine is ipv6 DNS. I have ipv6 DNS setup at work, and if I point it to that DNS server using "setprop x.y.sit1.DNS.*" (sorry, don't recall the exact setup procedure), than it still will not resolve ipv6 addresses. Nslookup (type=AAAA) doesn't work correctly either. Mine is heavily hacked stock 2.2 with a custom kernel. I just blew all the 'sense' layer away for the sake of battery life.
-- H
I use a cooked rom, not the official samsung 2.2
It has had busybox 1.16 installed.
But I went to the market and installed the app "BusyBox Installer" which then installed BusyBox 1.17.1 for me.
Sorry for not subscribing to my own thread, I had this problem licked back in January....at least on my Droid Inc. The problem is that /system is mounted as read-only. You need to remount with RW permissions and then copy or vi sysctl.conf to /system/etc/

Thanks for checking back. I'd still like to get this working on my own Inc. The case I'm most interested in is probably using 3g rather than wifi. Do you have an idea whether the Verizon 3g supports ipv6? I know we should be able to get it working in , for example, a dd-wrt flashed router, but it would be nice to be able to use ipv6 when there's no handy wifi.
Thanks - Hashi
Thx for the feedback.
I remounted system rw (can be done easily with "SGS Toolbox", or manually)
Ifconfig shows as long as wifi is turned on, there is an interface called eth0.
I added to the sysctl.conf this: "net.ipv6.conf.eth0.use_tempaddr=2"
I rebooted and ifconfig shows an ipv4 and ipv6 address.
But www.test-ipv6.com shows 0/10 at the ipv6 rating.
EDIT: Does /system have to be kept rw or can I change it to Read-only after placing the sysctl.conf?

External Bluetooth Keyboard Mapping with HTC Vivid

Hello,
I didn't know if there was already a post for this, my searches were coming up not matching anything.
If you happen to have an external keyboard (bluetooth in my case), you might have the problem that many of the key events from the keyboard do not map nicely to the HTC Vivid. I am running 4.0.3 in my case with 3.6 sense, and other than the alpha-numerics, many of the system level keys were not working for me. Since I often play HD video from my phone to the HDTV, it's handy for me to control things like Volume_UP/Down, HOME / MENU / BACK, Pause / Play, Select Movie title, reply to Text, etc. So I had to find a way to improve the keyboard mappings to make it functional, and I was curious if others may have done similar things as what I describe here. I am still stuck on a few mappings, so would glad to have any info from others who have succeeded or failed in a similar regard.
I went and spent about $35 for this G-Cube bluetooth keyboard model BK-30 at Frye's.
h t t p :// www .gggcube .com/ Upload/ ProImgs/ smaImg/ 201303101915016774.jpg
It was a nice weight with a good feel on the keys, and good enough for a test run. The bluetooth device was discovered and paired easily on my HTC Vivid, and some of the system functions from keyboard were working, like Volume UP/Down and Mute. But I noticed right away I had no way to open a MENU option, or to perform a BACK function from a given application or settings screen. In order to change the keyboard mappings, it's necessary to boot into Recovery, un-mount /system and use ADB to re-mount /system in order to be able to edit the file called Generic.kl (keyboard layout file) which lives in the /system/usr/keylayout/ directory. Here are the steps I used to update the file.
Before editing the Generic.kl file, it's helpful to gather some information using an APP called KeyEvent Display (free in Google Play store).
1. Download, Install and Run the KeyEvent Display application, it gives you a keyEvent monitor for the Bluetooth Keyboard
2. Pick a few keys on the Bluetooth which seem to do nothing, and press them, noting their SCANCODE values in the app. I chose the PrintScr, Pause/Break, Insert and Delete keys, just as a test. These 4 keys gave me scancodes of 99, 119, 110, and 111, respectively.
Now, you can reboot the phone into Recovery, and perform operations using ADB, providing your PC has the right USB drivers. Usually installing HTC Sync will give you these drivers, or from Ubuntu Linux, you may not need them. Google to install the ADB tool
1. Make sure your Vivid is rooted with a Recovery Image for bootup
2. Boot into Recovery, Connect your USB cable from the PC, and test that your ADB tool can properly communicate:
a) to use ADB, you need to have download these files (adb.exe, AdbWinApi.dll and AdbWinUsbApi.dll)
b) from the directory where you have ADB, test the connection with a simple 'adb devices'
c) you should get a response from the phone device like this:
[C:\Users\JohnDoe\ADB_Tool] adb devices
adb server is out of date. killing...
* daemon started successfully *
List of devices attached
FA27VVJ01452 device
Click to expand...
Click to collapse
3. Assuming you are successful, you can now send ADB commands to the phone as needed here below. (If you got nothing after List of devices attached, you can research this seperately - its usually and USB driver issue.) ADB commands are used to mount and unmount file systems (like /system), to send commands or open a shell to the phone, and to push and pull files back and forth.
a) adb remount (should see: remount succeeded)
NOTE: if this fails with an error, use your Recovery Developer options to un-mount /system first, then try again.
b) adb pull /system/usr/keylayout/Generic.kl
NOTE: Generic.kl is the file we want with all the mappings of keyEvents. If the file is pulled successfully, you see something like:
pull /system/usr/keylayout/Generic.kl
982 KB/s (9058 bytes in 0.009s)
Click to expand...
Click to collapse
c) Note with File Explorer in the folder with ADB, you should have a copy of the Generic.kl file.
d) Make a backup of this file, you can cause the keyboard and other items to fail with incorrect changes!
e) Edit the file with your favorite text editor, and look for sections that we want to change, for example:
key 109 PAGE_DOWN
key 110 INSERT
key 111 FORWARD_DEL
# key 112 "KEY_MACRO"
key 113 VOLUME_MUTE
key 114 VOLUME_DOWN
key 115 VOLUME_UP
key 116 POWER WAKE
Click to expand...
Click to collapse
f) Change keys 110 and 111 (for example) to now look like this, and then save the file:
key 109 PAGE_DOWN
key 110 BACK
key 111 MENU
# key 112 "KEY_MACRO"
Click to expand...
Click to collapse
g) adb push Generic.kl /system/usr/keylayout/ (this places the file back to the phone)
h) adb shell (need a shell to reset the permissions of the file)
i) chmod 644 /system/usr/keylayout/Generic.kl (should be read only to group/world)
j) ls -l /system/usr/keylayout/ (check to see ownership and permissions look correct)
ls -l /system/usr/keylayout/
-rw-r--r-- 1 root root 894 Jul 12 2012 AVRCP.kl

Click to expand...
Click to collapse
k) exit (exit from the ADB shell)
l) adb reboot (reboot the phone out of recovery into normal mode)
3. Now when the phone is ready, test the new key functions you have defined. For me, I had success with the MENU, BACK, CALL and ENVELOPE functions, among others. It is very helpful that I can use ALT-TAB to toggle between running apps.
The main one which I am failing to define is the 'OPEN ALL APPS'. If anyone else is performing mappings such as these for an external bluetooth keyboard, I would be interested to know which functions you have gotten to work. I am now at a state where I can control most everything, provided it is already running in the background. But I can't swipe my Sense desktop left and right, and I have trouble toggling certain switches like Wifi and Mobile data. Any suggestions or thoughts on these functions are appreciated.
Darren
Troubleshooting TIP: You can also run ADB when the phone is running in Normal Mode and you have the USB cable connected from your phoe to the PC. Then you can test certain keypresses through functions that are formatted in this way:
adb shell input keyevent 5
Click to expand...
Click to collapse
On my phone, this function will send the CALL event with brings up the phone from the desktop.
Other examples (you can also launch then from a *.cmd file):
If you have a terminal open on the phone, will send "ls -l"(includes the space-62 and enter-66):
@echo off
adb shell input keyevent 40
adb shell input keyevent 47
adb shell input keyevent 62
adb shell input keyevent 69
adb shell input keyevent 40
adb shell input keyevent 66
Click to expand...
Click to collapse
If you have a terminal open on the phone, will send "env|grep PATH":
@echo off
adb shell input text "env"

[Q] installing of app on device failed

I've recently returned to work on an app I developed while ago (targeted then to 4.4). at the time I had a galaxy s2 for debugging and now I have s4 (i9500).
I tried to run the app while my phone connected and got installation failed. So I installed Android studio and imported (converted) and changed target to 5.0.1 (my phone's version).
When I hit run (or debug) I get this message:
HTML:
nstalling myapp.leff.app
DEVICE SHELL COMMAND: pm install -r "/data/local/tmp/myapp.leff.app"
Aborted
Launching application: myapp.leff.app/myapp.leff.app.myappAppActivity.
DEVICE SHELL COMMAND: am start -n "myapp.leff.app/myapp.leff.app.myappAppActivity" -a android.intent.action.MAIN -c android.intent.category.LAUNCHER
Aborted
filltering the log-cat (Android) i've noticed this lines:

I've re-installed new version of my custom rom - result is the same
I took another phone (samsung s5) and install was success. connected my s4 again. same error.
And ideas on how to resolve this?

Hello,
Your project before conversion was built with Eclipse, if I understood it correctly? If so,
in Android Studio, the API targeting is not being read from the Android Manifest, but from the Gradle files.
In Android Studio, open (on your Project tree on the left), under the Gradle Scripts the build.gradle (Module: app) and check if inside the defaultConfig the targetSdkVersion has the correct API level. Then, press Build->Clean project from the menu bar on the top
If your application works with this String: INSTALL_NON_MARKET_APPS from the Settings.Global class , it is deprecated in API level 21, so use INSTALL_NON_MARKET_APPS from the Settings.Secure class instead. Check here.
I think it has to do with this class, the getString method with the above String that has been deprecated. I could help you further if I knew how is your app accessing this class or any code related to that
The S5 you tested has custom rom? Can you post the full logcat with the S4?
If you still need help, let me know

Getting UART working

Hello,
I'm trying to get UART output of gt-s6500d, but it's not working.
I've connected 620kΩ resistor between GND and ID pin, I got messages "AST_POWERON" and "BOOTING COMPLETED", however I cannot send anything on my own.
I'v tried
Code:
su;
echo "test" > /dev/ttyMSM0
(as well as tty0, ttyHS0, ttyGS0, ttyGS1) but nothing worked so far.
UART settings: 115200baud, no parity, no flow control, 1 stop bit, 8 data bits.
I've RS-232 connector powered with 3.3V, phone sends 1.8V signal but considering PC can read those two messages I assume this part is okay, I haven't connected phone VCC line, only ground, ID and TX.
Stock software and kernel, Android 2.3.6(S6500DXXMD1), kernel 2.6.38.6, phone is rooted and contains CWM recovery
Update 2018-09-28:
As it turns out 620kΩ resistor is ideal to get bootloader data, not sure if it even work with kernel, but I needed to add line
Code:
/dev/ttyHSL0 0660 system system
to ueventd.rc in initram to get one additional line on boot: "AST_UPLOAD" but the phone now is in a boot loop, maybe the boot.img is broken so bootloader send this information that uploading new boot.img is needed and restarts itself?
Bootloader outputs info with following resistors:
* 619kΩ (automatic boot)
* 150kΩ (manual boot)
* ~520kΩ probably works too
As it turn out I am unable to set cmdline to console=ttyMSM0 to allow any output from kernel, something (I think that may be bootloader) append this to cmdline:
Code:
console=null androidboot.hardware=qcom hw=3 androidboot.emmc=true androidboot.serialno=25db5e2a androidboot.baseband=msm
hardcoding cmdline into kernel seems only option for now
I'll update the post if I find out more
