[Q] Trying one-click root, keep getting 'cannot locate device' at command screen.

ok, trying to install one-click root on my Epic, i have up-to-date drivers installed, USB debugging is checked, my computer gives me the option to mount and it reads my device. when I go to the run.bat command screen, I keep getting the message 'cannot locate device, unplug USB, re-plug and press enter.' when I do that I get 'aborting script, phone still not connected' message. can anyone point me in the right direction or tell me what I'm missing, any help would be greatly appreciated.

Try to do a battery pull on the phone and try that. If that does not work, do a battery pull and reset your computer and see if that helps.
Not sure what OS you are running but the best thing is to do on Win XP.

Can you tell us the complete verbage of the error? I ran into a problem because I did not LITTERALLY UNZIP the rar file before running it. Kept saying the phone was not connected..but when I looked closer it was failing because the bat file was trying to run a piece of the program and for some reason it was failing on it. COMPLETELY AND LITTERALLY unzipped the rar to my computer and then ran it (making sure the phone was connected and in usb debug mode) and was rooted in a matter of minutes. hope this helped a little... good luck

Try plugging the Epic into a mobo usb port.

Your computer gives you an option to mount? If you have ADB debug enabled you should see something pop up in your device manager, but I'm not so sure you should get any kind of mounting pop-up.
Make sure you have all of the correct drivers installed for your OS, and try it again running each command seperately from the batch file. Then post here which command is coming back unsuccsessful so I can pinpoint the problem better.

I am having the same problem now for an hour or so. Tried everything I can think of , tried the all in one clockwork , used a different cable....i can hear my computer make that sound when I plug the phone in , and also when I unplug it. Just trying to get clockwork on here , ive read and read and read all the threads I can find. Got good drivers , windows xp. Rebooted laptop and phone at least 20 times ...dont know what else to try

Look in your device manager on your pc while your phone is connected with usb debugging and make sure there is no question mark next to Android ADB device. It needs to recognize this driver for it to connect.
HI
Hi i had that same issue an i went to the samsung official website becaue my phone can't connect to my pc i couldn't see my sd card pop up so the guy say my phone was defective so im thinking you have the same issue as me but samsung is fixing my phone now for free an free shipping i hope you still have warranty on your epic an they flashing a new rom an software on it for me they say to fix gps an wifi issues i had too
Got it to work, it was a driver issue apparently. Downloaded drivers again, completely removed old drivers. Reboot PC, make sure phone isnt connected yet. After reboot, install drivers, reboot again. I also had my phone turned off this whole time. When PC came back up , turn phone back on, connect using one of the main USB ports, not one in the front or anything. You should see windows detect and install the software. Then I ran the all in one clockwork , and here I am now fully rooted, syndicate rom , so much better than stock...hope you get it working! I definitely almost gave up a few times

[Q] Connect Mesmerize using USB Cable

Help! Absolute newbie. Windows 7 computer won't recognize my phone when I plug in using stock USB cable. Rooted using Z4 root. Still has firmware 2.1 update 1. Having same problem with wife's unrooted phone. Only recognizes phone as composite USB device. Samsung driver installed, still doesn't work.
Make sure your phone is set to mass storage or ask on connection in Settings > USB settings (I'm assuming you want to transfer files to/from the SD card). If that's set, something should show up on your phone to let you transfer files to the computer when you connect it.
It is set for Ask on Connect
It is set for ask on connect. I am trying to update (upgrade?) to Froyo.
Oh ok. Sorry, it's been so long since I did that, I don't remember enough to be much help. If you can't get that to work, there's a thread on here somewhere with stock Froyo Odin files you can use.

Wife's stock phone worked
My wife's unrooted phone worked. Can't get either laptop to recognize my phone as a phone. Keeps coming up as "Composite USB device." When I try to use Samsung Drivers, I get error message 10, can not start drivers. Is there something I can change to have computer recognize it as the proper type of device?
if you want to do the official update you have to get samsung kies from uscc website, if unofficial you have to download odin, go to the first thread in mez android development it tells you all you need to upgrade.
They don't see my phone.
I have Kies Mini. It doesn't see my phone. Nor does SuperOneClick. And now I can't get Z4 to work either. Getting worse and worse.
Do you have USB debugging enabled on your phone? And you aren't Enabling Mass Storage correct?
Thanks
I am following the written instructions on the US Cellular website exactly. I spent over an hour on the phone with tech support (Thanks to Holly in OK for her patience) but failed. She recommended either I wipe the phone, with no guarantee of success, or take it to a repair facility. Took it in. They know about the issues with Froyo on this phone and recommended I wait 2 or 3 weeks until Samsung comes out with an update to Froyo. Just for grins, I asked them to plug my phone into their computer to see if it would be recognized. No joy there either. They also recommended I wipe phone. I decided to wait until the update for Froyo comes in. No sense reinstalling everything twice. My wife, who's phone did update, was added to the service ticket so we will be notified "when the fix is in."

Are you using the cable that came with the phone? My buddy had that problem, he was using a old usb they had laying around and thought it would work because he uses it to charge?
Stock cable
I have tried both cables, one from my wife's phone and one from mine. Not sure what they used at USCC store. Thanks for input.
USB not working after 5/5/11 Heinz flash
Love the Heinz 57 ROM but I can't get drive recognized on PC. Fixes I've tried:
rebooted
reflashed ROM
tried different USB cables
tried different pc's
reinstalled Samsung drivers on PC
checked debugging
tried using Mass Storage option and ask on connection
unmounted sdcard
Now I'm at a loss
Thanks in advance!
fixed
rebooted pc seemed to have fixed the issue for now! Going to start playing with boot animations....
What works for me:
- turn Mass Storage on in USB settings
- then turn on USB debugging also
- go back to USB settings and change to ask on connection
- plug in phone, and select mass storage. Then scroll down notification bar and select copy files to/ from
It's a lot of back and forth, but is the only sure thing I've gotten to work. It also has to be redone in that order every time after turning it off.

HTC Sensation wont connect to PC (only charge)

Hey, i have had my sensation about 2 months, now when i connect it to a pc it dosnt ask what connection type to choose, it only charges, in the menu it is set to ask me about connection type, while connected to pc there is now no icon in the notification area (used to say 'charge only' or 'disk drive') even when rebooted into 4ext recovery and mounted/toggle usb connection, it dosnt connect as a disk drive like it has always done in the past, it only charges, i have tried 3 different pc's and 3 different micro usb cables, also have tried updating the firmware to 3.24 and installed ICS with the same result, i think its a hardware issue? last time it worked was 3 days ago connected via usb to a jvc headunit listening to my music files.
Weird problem!
Maybe you could try with a different SD card to eliminate the possibility of it being an SD card problem?
If it still doesn't work with another SD Card it may well be a hardware problem.

Well I had the same problem with the custom ROM I use.
Installing it clean with a full wipe solved it.
It is definitely NOT the pc, laptop or SD-card.
Are you on a custom ROM?
- Yes then install clean with full wipe. (make a nandroid backup!!!) and install all apps new.
- No then do a total reset (reset to factory settings) and do all the install stuff new. After that you can also install with RUU your ROM designated for your device.
You will see your USB connection will show up!!
same here
i have exactly the same problem as described in op.
will try flashing a new rom then also; first have to buy a flashcard reader then to get my new rom ON the sd card....
or do you think a nandroid restore would fix the problem? will try that first.
Will report back
The nandroid might restore the problem.I'd try it first.if not , then do the full wipe reinstall as said above .if at the time of the nandroid back up it was working is a good possibility it will fix the issue. Hope this helps!

Couple of tips that might fix your problem.
If you're running aokp make sure you disable fast charge.
Turn on mtp in USB computer connection settings. I have trouble accessing the options from most custom roms, so a little work around is to install either apex or nova, long press add to home screen - shortcuts - activities - scroll down to Settings - USB computer connection(com.android.settings.usbsettings) . Tap it and you should get a shortcut. Select mtp.
Ultimately, the thing that fixed my same issue was getting a different USB cable lol. You can also try different ports on your computer.
Good luck, hope you can find a solution to your problem! If all else fails, you can try using airdroid for transfer over Wi-Fi
Anyone find a fix on this , mine has started doing this yesterday :crying:
Tried 3 different cables , different usb ports , different sd card , formatting sdcards in 4xt recovery , reflashing firmware.... also htc sync re installed for drivers (htc sync does not see the phone), adb re installed (adb does not see the phone??)
dont think its the rom as adb cannot see the phone in fastboot
anyone any other ideas , tried ninjasalad suggestion on enabling mtp also ??
I think you're fine. I had this problem after flashing ARHD 6.6.X, OrdDriod series, and PkMn series. What I did was the following:
Went into settings. Connect to PC. Unchecked the "ask me" , Restart phone. Then checked "ask me" again. Lastly, restarted phone again.
After doing that a couple times, it worked for me. Maybe you can try that.
This happened to me as well. I think it's a hardware problem

check these
make sure you have enabled usb debugging mode from settings
install htc drivers
install htc sync(i am not sure if it is necessary)
use 2.0 usb ports
use the original usb cable if you aren't using it yet
wont work, screen broken

I can't do that because to enable usb debugging mode you have to use the phone and the phone's screen is completely broken and there's no way to even get into it using the touch screen.

[Q] USB on Windows 7

I have a strange issue with my G2x. A couple of months ago I was trying to sync my music with my phone and the computer wouldn't recognize the phone as a disk drive. At first I chalked it up to the computer I was using at is was old and hadn't been rebuilt in quite a while. I had installed the LG USB drivers already, but just for kicks and grins I installed them again. Still nothing. I decided to rebuild my computer and reinstall the LG USB drivers. Still nothing. The phone charges, but Win 7 doesn't see it.
Fast forward to yesterday. I want to restore my phone to stock so I can get the new BB & stock 2.3.4. I installed the APX driver and when I plug the phone in, I get an error code 10 in Device Manager - the device cannot start. I researched that and found nothing helpful. I tried using another computer that I know used to work with that phone, still nothing. I tried the LG Phone updater - it can't find the phone either. I also tried the KDZ updater - it can't find the phone either (even with the phone in Software Update mode). I also tried several different USB cables.
The phone is rooted and I can change between ROMs with no issues, provided I pull the SD card and copy the ROM to that, or download it directly to the phone.
I think the USB port on the phone is hosed. Any suggestions on how to get the updated BB & 2.3.4 on my phone so I can get a warranty replacement?
[edit] - I am on Windows 7 64 bit.

Do you have USB debugging turned on in Settings, Applications, Development? That may help get connected to the Win7 PC.
Yeah - USB debuggin is on.
I had the same problem a little while ago. The solution for me was to install the drivers throught the updater application available on T-Mobile's website. I'm not sure why directly installing the drivers doesn't work, but that's just how it is for some people, apparently.
---------- Post added at 02:57 PM ---------- Previous post was at 02:56 PM ----------
Oh, and turn debugging OFF
Yeah, i would turn off usb debugging, as then you can't get to USB Mass Storage. I would also try uninstalling and reinstalling the LG USB Drivers, and then try it again.
I have tried all manners of the solutions presented. Installing drivers from the LG Update tool, from the LG website, with and without USB debugging, with and without the SD card (saw that somewhere else). The more I work on it, the more I believe the USB port is bad. Thank goodness I can still charge it. The guy at the T-mobile store states I can get a new phone in 3 months. So I think I will just live with it for the time being.
What ROM are you on? I remember having problems with some of the ICS ones.
Kinda shocked no one said did you make sure you have USB set for mass storage? Thats usually the most common thing to miss. If your using ICS I'm gonna take the guess of HFS? Which i know for a fact he posted the update morfic kernel so you can use mass storage. If your not using HFS, then you should try it first and then worry about the USB.
This is ROM independent. I've used pretty much all ROMS for the G2x, most recently Owain's ICS, Weapon and right now HFP - all experience this issue. As stated in the original post, though, it doesn't work with the APX drivers when trying to flash CWM or go back to stock. No matter which ROM, when plugging in to Windows, there is not the distinctive sound that a device has been added.

Check your device manager in the properties (open computer, right click, selct properties, should be the first or second option on the right side, will open in a new window). Open the option all the way at the bottom and you should see something like USB ADB storage device. If its there then you should be able to access it. USB debug and USB mass storage should both be on, try adding "allow mock locations," and if none of the above work, try doing it the old fashioned way. Get the Micro SD adaptor and plug it into the computer that way.

Cant connect to computer through usb

so im trying to download some files on my compo to transfer to phone so i can unroot it and send it back to verizon. im on the latest beanstalk rom and when i hook up my phone to the comp, its saying unable to recognize the phone. any suggestions on what to do? i have debugging turned on in the developer options as well. thanks
Check drivers and try battery pull
ive restarted the phone and i havent had trouble in the past but ill double check the drivers. thanks
figured it out. its because i have kies installed. tried returning to stock through heimdall but was having an issue and installed kies for that. thanks though
I tell you what, I'm not a big fan of MTP especially with ubuntu. I had issues mounting, until i figured it out in Qualcomm usb settings in hidden menu. You would think our phone would mount easily out of the box.

For awhile I had no issue. Even after I realized that I had kies installed and uninstalled it, still had issues mounting it. Couldn't get it and couldn't get the file I need to flash in mobile odin. I have an old Mac btw running 10.5.8. I'm going to have to use a friend's comp to both root my new phone and transfer a stock Rom to return my phone to factory.
