[Q] EVo user trying to root my girls epic

Hey guys I an having the darnest time root this guy should be easy with these one clickers programs.
Pretty sure its a driver thing, note I can see the device when in cmd and doing the adb devices that shows up. just gets hung up at the end there.
attached a pic of what the cmd line looks like
anybody have the current drivers, googling for them just yields me to forum posts asking where the drivers are

thirty views and nothing

ok its not a driver issue if your loading root.sh (the big block of text) the issue is that the adb server isnt starting back up in time in order for your device to be recognized. solution? open up the bat file and copy and paste the commands one at a time; or if you have a linux/osx computer try doing it there with my scripts in my sig

couple ideas..
1.open up the run.bat file in notepad or similar and go through all the commands manually, that way you have control on speed of commands and allow enough time for adb to startup again.
2. open up the run.bat file and increase the wait time in the script.. -w 3000 or something like that..
i would suggest you do commands manually. The one-click root did not work for me but doing things manually worked right away.

How to do it
Hey man this is how I got it to work. I was having all the problems device not found etc etc. Have been trying since Sunday. What I finally did after installing the drivers was restart the computer and Phone. After that i tried to run the program it failed with device not found again so i unplugged the usb cable from the phone and closed the cmd window. And also brought up Task manager and killed the adb.exe process. then i reran the run.bat file and this time when it gets to the adb restart relogin apart i killed the SMALLEST ADB.EXE IN THE PROCESS TAB OF TASK MANAGER and that is when it finally got it to work. Had to do the same when I tested it with the uninstaller. So that seems to work. If anyone has any questions feel free to pm me.
But thank god it finally worked.

other people have done this and it worked for them also.

I tried all kinds of stuff ultimately I ended up using an xp machine. I later remembered the whole xp mode in windows 7 but didn't actually try it ... win7 just gave me a hard time although the post about changing the amount of time to restart adb makes sense

[Q] "adb server didn't ack * failed to start daemon"

okay, I devoutly hope someone can help me here, because I'm at my wit's end with this. I'm using windows 7x64. I followed the instructions in THIS thread first(after installing the android sdk directly from the main website ), and got through everything okay, but when I try to do anything with adb(adb devices, for example) I get
"
*Daemon not running, starting it now on port 5037*(this does successfully start the adb.exe process)
ADB server didn't ACK
* failed to start daemon *
error: cannot connect to daemon*
"
Here's what I've tried so far:
1. Killing and restarting the adb.exe process, both with task manager and with adb kill-server(which is the only adb command I've found that does anything other than return an error message)
2. reinstalling both the drivers posted in this thread and those at nookdevs
3. rebooting both the computer and the nook color multiple times.
4. deleting all SDK files and both re-downloading and re-installing.
5. deleting every file I could find and the drivers and following the Nookdevs instructions. same problem
6. using the adb_wireless app, where it tells me to use adb connect <iP address> after running the app. same error message appears. Because of this step I'm less inclined to believe that it's a driver error, since the wifi app bypasses the USB driver, at least as far as I understand. I do, however, believe my drivers are installed correctly, I have ADB Composite android device in the device manager
The only google results I got with this error(for different devices) referred to the port adb needs being locked in to something else, but that doesn't appear to be the case here, I see nothing running on port 5037 in netstat
Thank you for taking the time to read my short novel, and I appreciate the help.

*shameless bump*
seriously though, 65 views and not a single person with even a suggestion? would this be better off in a different portion of the forums? Any advice at all?

dumb question, but with out the NC plugged in, when you type in "adb devices", what get's returned?
if you get that error message, than that's a config symptom.

Hey i'm no pro and got adb to work on accident...What i found is that the android sdk folder needs to be in your user folder. So when i go to start and click my user name my android sdk folder is in there with my downloads folder, desktop folder, and music folder. Makes sense? ALso any thing i push to my device i put into that folder in the tools directory. I found that that fixed most of my problems as i had the folder in the root of my c drive. Let me know if that helps.

No luck there, but thanks for the reply anyway. gives me the same error. I suspect in your case that you were not getting into the c:\android-sdk-windows folder and moving it to your username folder fixed that problem because that's the default path when you open a cmd prompt. Thanks for trying, though

Last thing i can think of is maybe your firewall? Kill it for a few mins and see what happens.

Still happens when the device isn't connected. I agree that its a config error rather than a driver issue. Also, disabling my firewall has no effect. Thanks for the suggestions though

ADB worked for me for months. I used it regularly. The last thing I did was *trying* to use Wireless ADB Widget and issueing ADB TCPIP command. I have made no changes to the system.
The error occurs when no device device connected. Same error when device IS connected.
-Downloaded ADB/SDK again to a different directory, same error
-Updated USB driver and SDK components, same error
-Disabled all firewall/anti-malware/anti-virus, same error
-Rebooted multiple times, same error off boot
-Port 5037 is not bound by any app or process
-ADB, upon failed load, is not listed in Taskmgr, nothing to kill
-Deleted temp files
-Issued at prompt: ADB Disconnect, ADB USB, ADB devices: All return same error as above
-Issued at prompt: ADB kill-server, only prompt returns
Read lots of posts on the web, nothing helps.
I am really interested in a solution and would like to understand what is causing the problem. If in fact it is a configuration issue, where is the ADB config file?
Thanks.
Edit: I am running the command prompt as an administrator.

not sure what was causing the issue, I ended up reformatting my HD and re-installing, it worked fine after. Sorry I couldn't be of more help, I looked everywhere for about 2 weeks and didn't find a thing that worked

Wow... I would hate to have to rebuild my computer just to get ADB back. I will post this in the Evo forum and see if there is some help.

Force close with music

so i transferred my music from my laptop to my tab, but while looking at my music on the tab it all of a sudden exits and asks me to either force close or report. Anyone have any idea why this could be happening? I thought all was good once i got the files to tranfer, but then this happened...

could you try reproducing the issue with logcat running?

Sure, would you mind explaining how to do that though? Not wuite sure what logcat is... Appreciate all the help! Hope to get this squared away.

yeah, I figured I would have to do that but I hate writing out instructions just to find out that the person already knows everything I had to say.
I'll write this assuming you're using windows.. hopefully that's not a mistake
this may be a lot more work than you're willing to do and it may not give any useful results. you're certainly more than welcome to try it though.
for a much easier, but less helpful method, skip to the end.
first, install the adb driver. there is a link floating around somewhere to just the driver, but I can't find it so you're probably better off just installing samsung kies. this will install the drivers for you.
http://www.samsung.com/ca/support/m...softwaremanual.do?page=MOBILE.SOFTWARE.MANUAL
then, you'll need to download the android sdk.
http://developer.android.com/sdk/index.html
download it, open the sdk manager and then let it install it's stuff. all you really need is "Android SDK Platform-tools, revision X." I believe the most recent revision is 5, but it doesn't really matter.
now, open a command prompt. in windows 7, you can just hit start and then type cmd. in xp or vista I believe if you have to use start->run or windows key + r, then type cmd and click run.
from here, change directory to the platform tools folder of your sdk. most likely something like this
Code:
cd C:\Program Files\android-sdk-windows\platform-tools\
though it will depend on where you installed your sdk
now go into settings->applications->development and check "usb debugging" on your tablet. after that is done, connect it to your computer with usb and type
Code:
adb devices
if something shows up, your device is recognized. otherwise.. ask for help, I guess
finally, type
Code:
adb logcat -c
adb logcat
and then try to reproduce the error. this will give you tons of information about what's going on in the system. hopefully, it will give you some idea why it is crashing.
Note: the "-c" will clear all previous logs
now, for the short version.
In the android market, download "Android Terminal Emulator"
attempt to reproduce the error then open the terminal emulator and type
Code:
logcat &
this will show you all logs since the last reboot, assuming you haven't cleared them with "logcat -c." It might be a good idea to use "logcat -c" before you start trying to reproduce the error.
hope that helps,
Sam

First of all cant thank you enough for trying to help out. So i went with the second option as to limit my chances of having to ask more questions...yeah about that. With option 2 i could not run the "logcat -c" and after reproducing the error and running "logcat &" i get a permission error... Ideas? Thanks again!

hard to say, man.. what does the error say exactly?

Can't get Hello World running

Hi Guys,
I'm trying to start some Android development however I've run into a couple of problems during Dev environment set up. I've been following the adt-bundle install instructions as I opted to use the ADT bundle.
This first problem is that the Android Virtual Device Manager will not run. I get a message saying "Failed to execute tools\android.bat The system cannot find the specified file". No idea what to do about that one.
The second is that I cannot run my app. I'm trying to run it on my phone (HTC Desire C) how I keep getting the message :
Code:
[2013-07-13 07:33:37 - MyFirstApp] ------------------------------
[2013-07-13 07:33:37 - MyFirstApp] Android Launch!
[2013-07-13 07:33:37 - MyFirstApp] The connection to adb is down, and a severe error has occured.
[2013-07-13 07:33:37 - MyFirstApp] You must restart adb and Eclipse.

I've tried resetting adb via command prompt using adb kill-server and then restarting using adb devices and checking that a device is connected however it doesn't seem to make a difference.
I've also tried connecting my N7 tablet up and install the usb drives in the sdk and I get the same errors
It's incredibly frustrating and I would really appreciate some guidance.
Thanks in advance
Samishal

is your adb there? and is it executable? (are you running as admin?)

I have also got same error AVD error.. ihad solved it by opening this file "C:\android\sdk\tools\android.bat" and updating its component..

Ipython/Jupyter Notebook on Android

Hello All
I was able to successefuly install Ipython(jupyter) on my nexus(2013) and wanted to share the procedure with all that could be interested.
You could learn and read about Ipython[Jupyter] here
CAUTION:
> To the best of my knowledge this is the first tutorial of it's kind.
> I strongly recomend that you try this on a fresh rom. Use MultiROM for instance
> This was tried on Nexus 7(2013) with android 4.4.4. But I see no reason why it shouldn't work on lolipop 5.0 or on another android tablet. [You could try at your own risk and report your findings]
> Allow minimum 4Gb free space. I used rougthly 2.2 Gb, but i installed more than just ipython
> Hackers Keyboard is VERY HANDY if not NECESSARY
> I apologize for typos and gramar mistakes in advance
> Some of the following steps take time (a long time). Just make sure your tablet is connected to the charge and chose to keep the screan ON while it's on charge
> I am UNLOCKED and ROOTED. I can't tell whether it is required. If it is it would have to be with the prerequired apps. YOU WANNA VERIFY THAT before anything
> MOST IMPORTANTLY, DO THIS AT YOUR OWN RISK. I'm NOT RESPONSIBLE for any INCONVENIANCE whatsoever.
Procedure:
1-: Install GNURoot WheezyX . I am more confortable with debian, tryFedora or Gentoo ... If you know what you are doing.
2- Install GNURoot
3- Open GNURoot
4- Chose wheezyx (or fedora or gentoo ... depending on the distro you like) in the "Select Rootfs to Create " drop-down menu.
5- Click on 'Create New Rootfs' button
6- Chose wheezyx(or fedora or gentoo ... depending on the distro you chose) in the "Select Rootfs to Launch " drop-down menu
7- Check 'Lauch as Facke Root' box. This will give us root privilege
8- Click on 'Lauch Rootfs' button
At this point you shoud have 'Terminal Emulator" open up a window with '[email protected]:/# ' and a prompt ready to take instrucktions
Welcome to linux !!!
Now we need to install "python" and "pip", but before that we need to install 'build-essentials' which will make 'gcc' and all tools required to build a package available on our linux platform:
In the following: if you chose wheezy distro it's the same procedure; if you chose fedora distro replace apt-get with yum; if you chose gentoo you are on your own because I'm not familiar with it
Anyways I assume no responsability anyhow whatsoever.
9 - At the prompt type 'apt-get update' and press Enter
10 - Type 'apt-get upgrade' and press Enter'
11 - Type 'apt-get install build-essential' and press Enter' : This will install "build essential"
12- - Type 'apt-get install python' and press Enter' : This will install "python". I got the version 2.7.3 . You could find the version you installed by typing "python -V" and pressing Enter
13 - Type 'apt-get install python-pip' and press Enter' : This will install "pip", the python package manger
At this point we have python setup in the linux environement. Let's finally install ipython:
14-a Type 'pip install ipython' and press Enter if all you want is the ipython interpreter
15-a Type 'pip install ipython --upgrade' and press Enter to make sure you got the latest version
or
14-b Type 'pip install ipython[all] ' and press Enter if you want ipython and all the goodies like notebook
15-b Type 'pip install ipython [all]--upgrade' and press Enter to make sure you got the latest version
I do scientific work with ipython, so if you are on the same boat as me you could install scientific packages numpy,sympy,pandas,nose,.... with:
"apt-get install python-numpy python-scipy python-matplotlib ipython ipython-notebook python-pandas python-sympy python-nose" !!! This is a lot about 1.2Gb !!!
At this point everything is set up. "when the wine is drawn, we now just have to drink it"
16-a Type ' ipython ' and press Enter to run ipython interpreter
or
16-b Type ' ipython notebook' and press Enter to run ipython notwbook. If you get an error message say that ''no web browser could be found" ignore it. look for the server address (looks like http://localhost:8888)
17-b Enter that adress (http://localhost:8888 in my case) in Chrome (I had no problem with chrom so far, but you could try on your favorite web browser) press Enter. Et voila you should be in the ipython notebook tree
I have been here for a couple of years, and never got to share anything.
This is my first thread, and i hope it is the beging of a very long series of contributions
> I will upload screenshots later to better guide noobs (I was one onece)
> PM me if you like to donate. I would appreciate it
> Please support the GNURoot developpers, or ipython[Jupyter] developpers if you can. They are all doing a terrific work. (I'm in no way associated to them, but love and support their work)
> I'm not very good at making videos, but I welcome any initiative.
You now Know how to install ipython, I trus you could be very creative since you now got linux at your finger tip :laugh:

Help to use pandas + matplotlib: no $DISPLAY environment variable
First of all thank you for this pretty cool tutorial
i did it and everything else works after all that huge pip installation!
my problem is that i need to see the result of my codes which sometimes is to show me plots of my data using the library matplotlib.pyplot
when i do that i get the following error:
TclError: no display name and no $DISPLAY environment variable
i found someone with the same problem in another situation (not on android but something like trying to save the plots in a pdf) and the problem was solved doing the import like this:
import matplotlib
matplotlib.use('Agg')
import matplotlib.pyplot as plt
plt.plot([1,2,3])
plt.show()
By using matplotlib.use('Agg'), python knows to use the non-interactive back-end Agg instead of trying to display to the screen
this means that i don't have anymore the error but the plot won't be shown either
this happens not only when i do python file.py from command line but also when i run the same codes on jupyter notebook
so is there a way to execute file.py so they do what ever pandas want to do in this android environment (especially pop up windows with my plots when I execute the files)?
if there is no way how do i get rid of android to install some better OS on my tablet that can do all this kind of stuff?
thank you but all of this that you have done it's really not that useful if i cant see my plots
let me know!

You should know that the linux running GNURoot doesn't have an X-session. You kinda need x11 installed on it to be able to have windows popping up and showing your plots. I remember trying apt-get install x11 without success on "Wheesy". Now, I know there is the "wheesy X" distro of GNURoot, but I don't know whether the X stands for X-session capability; I suggest you try that. (I no longer have my nexus7 to try, but it would be nice to see what happens).
I was able to go around this problem by working on the notebook. I could see my plots fine. I remember firefox beeing the best browser to work on the notebook.

Plots at least on jupyter and transfer files
hey so i found this : (i dont have authorization to post links normally)
stackoverflow .com / questions / 18353203 / using-python-and-matplotlib-on-android
where someone is stating is a big deal to have plotlib working on android
jupyter notebook is not displaying plots not even on firefox, it always give the "TclError: no display name and no $DISPLAY environment variable". It would be awesome if you'd give me a straight solution so i can see plots on jupyter! that would be more than enough to follow lessons in class
the temporary solution i found for now is to remote control my pc at home from the tablet to do all the coding but i cannot work without connection this way
i also found out about this website Wakari but they are saying now there isn't anymore free space for new subscription..
the best solution would be to have plots displaying on jupyter with your help
so the plan for now is to stick to let the pc at home do all the work and remote control it with the samsung remote pc app or to find a good website to log in from the tablet and write codes on browser
ill still use this command line of yours when ever i can thou, when ever there is nothing to display i guess.. but how do I find the folders so i can move to the desktop computer the .py files or the notebook files i create? i was expecting to find the files when i was connecting the tablet with usb wire.. is there anyway to transfer those files?
thank you
