Device not recognized

I have a pretty big problem and need some guided help. My stock samsung usb charger sometimes charges the phone and sometimes does not. Tried multiple different chords and got the same results, sometimes works sometimes does not. So now I am assuming this is an internal hardware problem soo I decided I should flash stock images, unroot and relock the bootloader and here comes the worst problem.... My device is NOT recognized when I connect it to my PC... therefor I can't access adb connection to flash stock images so I can return it to VZW....
Not sure what to do next.. any suggestions would be great...

It sounds like you just don't have the drivers installed. Just install the Samsung drivers here.

I tried that. uninstalled the old ones (that worked for 3 months) reinstalled them again and still no luck..

Do you have any other Android processes running on your cpu? Droid Explorer or alike? Droid Ex **** blocks adb; I had a frustrating few minutes once when adb wouldn't connect to my device until I realized DE was running in the background.
Long shot, but just a thought.

This is actually a common hardware error. See http://code.google.com/p/android/is...ary Stars&groupby=&sort=&id=23789#makechanges and http://forum.xda-developers.com/showthread.php?t=1427539
Basicly you need to buy a new USB charging board.

Yeah I believe that is what I am going to do, I just have to find the sch-i515 CDMA version because I am finding a lot of GSM versions out there right now.

Sure. My adb command prompt does not recognize my device therefor I cannot execute any commands ei fastboot.

fastboot doesnt have anything to do with adb; boot your device into bootloader
'fastboot devices'
do you see your device?

I am in the bootloader and don't see 'fastboot devices' or do I see my device. I see the product name, variant, bootloader version, baseband version, etc. Would that be considered 'my device' being recognized and I could actually flash the stock images?

fastboot is like adb. You need to run it from a command line. You should have had to use it when you installed a custom recovery ('fastboot flash recovery customrecovery.img') or unlocked your phone (ie 'fastboot oem unlock'). fastboot is part of the android sdk (think it's in tools folder, but I moved mine so am not sure).

That's what my understanding of what it was too. I'm in the bootloader running a command prompt through windows and for the first time I think it recognized my devices. I ran 'fastboot devices' and a bunch of numbers on one line came up followed by fastboot. So I think my device is recognized and I can flash stock images?

yes, you can download the images for your device from google and flash them to your phone using fastboot if you want. I'm pretty sure that would put you back at stock with an unlocked bootloader.

@op, next time read how to flash/get back to stock before flashing anything. there must be like a dozen of topics in xda about this ****.

I know how to. It was just your demeanor and wording/phrasing that had me confused.

I have the same problem, fastboot was working this morning, now after flashing Revolution HD, typing "fastboot devices" in CMD doesnt return anything anything, neither does adb push command which replies failed to copy .... As if the phone doesnt exist or its not attached. Does the phone need to be in clockwork mod? or just boot the phone normally?
Edit: This should do the trick, open CMD in Windows, navigate to your c:\android where you have fastboot and adb stored and type:
:cd %:h
adb kill-server
adb reboot bootloader

debugging has nothing to do with it.
Windows XP absolutely HATES the samsung galaxy nexus.
The don't play along and it's almost impossible to get the drivers (especially MTP) installed correct.
Fortunately I have a W7 BEAST rig at home.. But the work XP pc can't handle the Nexus

htc one x stuck on boot logo

was trying to flash cm10 onto my one x from this website:
pocketnow title "Jelly Bean on the HTC One X with CyanogenMod 10 (Video)"
ended up getting stuck one #8 because i assume "Shift+right click in the browser window" means do that in the android sdk program. now my one x wont be able to boot because on my pc it wont work but im now try to attempt at it with my mac. any suggestions on how i can boot it up? even it i do volume down+power button or volume up+down+power button it restarts but stops at the boot logo. your help is greatly appreciated, thanks.

Did you flash the boot.img?

Shift + Right Click is usually done in Fastboot folder (for me) then click "open command prompt here" to use fastboot commands

Can you use fastboot commands with your phone?
If so then extract the boot.img from the rom you want to use, and copy it to the fastboot folder, then right click and open command prompt in the folder and enter the command fastboot flash boot boot.img

yes it shows up as red when it says "FASTBOOT USB". damn this 5min per post is annoying

Sounds like everything should work, have you extracted the boot.img from the rom?
place it in the fastboot folder on your computer, then shft+ right click and open command prompt and you should be good to go from there with flashing the boot.img

In that state try typing fastboot devices
You should something like HTxxxxxxxxxx fastboot
If the response is blank then you may not have the correct drivers installed for your phone. There are a number of ways to get the drivers; one way is to install PDAnet http://junefabrics.com/android/download.php
You don't even have to complete the whole install, just go until the driver is installed. In any case you can uninstall PDAnet and it will leave the drivers on your system.
When fastboot is finally able to recognize your phone then you can flash the boot.img by doing fastboot flash boot boot.img
(this assumes that boot.img is the actual name of the file, it should be unless you renamed it or downloaded it from somewhere)

is fastboot just a folder i create with the boot.img inside of it?

No, fastboot is a tool within the Android SDK. You used it when you unlocked your bootloader.

i bought this phone off another guy who had it rooted and loaded

where is the fastboot folder located in android sdk manager?

Download this file http://www.mediafire.com/?50baad8rykng2j0
Create a folder on your C: drive called fastboot and extract the .zip into the fastboot folder

ended up bringing my phone to the cell shop. I know its an easy fix but cant seem to find that folder.. they said it was a 50/50 chance and will charge me $80 if they can get it to work...think it was a good idea?

Not really. Seems the only thing your phone needed to boot was the boot.img. That would have been done in a couple minutes. As already said here: you simply need to put the android sdk on your c: drive, put the boot.img in that folder, go into bootloader and connect your device with your pc, it should say fastboot USB, open command prompt, go to the direction of your sdk folder and use the fastboot command to flash the boot.img. It should then boot.

Where can I find an IMG file to flash via fastboot to unbick HTC One X International?

ADB is not seeing phone, so need to flash an img file via fastboot to bring HTC One X international back to life. Alternatively, let me know how I can get ADB to see the phone - I've tried reloading drivers and universal driver. Thanks.

What state is the phone in? Are you able to boot at all? To recovery or bootloader? I don't have that phone but might be able to help. Reach out on Hangounts if you wish.

Thanks. I can access recovery and overloaded. Don't know any way to transfer roms to phone as adb not seeing phone.

what recovery do you use?
If TWRP what if you go under advanced and try using the adb sideload option...maybe that will make your pc see it.
When you are in bootloader are you able to see device using fastboot command?

It depends on the OS you're operating with. Just try before:
- locate "adb" files (4'v'em) into "C:"-directory and reboot, then connect your phone. Check if "ADB" runs on OS Startup.

Im having trouble with fastboot when returning to stock

Hi guys, i want to return to stock (i.e relock my bootloader and install stock oxygenOS) but i cant get my laptop to recognise my op3 whenever i type "fastboot devices" in cmd. Ive tried multiple programmes to install the correct drivers but it just doesnt seem to work.
Has anyone had similar problems or any solutions??
Im currently running windows 10 on my computer
Thanks

Do you have fastboot / adb tools installed and phone is in fastboot mode?
What does it say when typing fastboot devices?

Thanks for the reply, I type fastboot devices and nothing follows just another line to type a command. I'm pretty sure I have adb/fastboot tools installed, I used an installer which was linked on another thread

No. Thats independent of OS
Are you in the fastboot/adb folder, where fastboot.exe is, when typing in cmd?
The mode where you should be is called "bootloader" on the phone.

Yeah that may be the problem, would you mind directing me as to where I can find this fastboot/adb folder so that I can determine if I've even installed it properly haha

Well, if the cmd does not say something like "fastboot was not found", then that might not be the problem.
In which state is the phone, when trying fastboot?

Wrong drivers... Make sure you install the right one. Preferably follow the first few steps of the unbrick guide go get the right ones.. You are probably using the ones by Windows which do not work.

And always blackscreen. Nothing show or display

Have you enabled USB debugging?
To enable USB debugging you need to enable Developer Options in your phone first. To do this: Go to Settings > About phone > Software info > and then tap the build number about 7 times.
Edit: I can see you have downloaded the Android SDK Platform-Tools on the desktop. Try to run the command under the correct path ( C:\Users\XXXX\Desktop\platform-tools_r33.0.2-windows\platform-tools>

Indeed. I have definitely lost my mind.

Use android flashtool. You can't downgrade on official a13 and I think you have to flash it to both slots or use flashtool

Yes i have bootloader unlock. But totally blackscreen now. Any button do not work.

If ADB and Fastboot still work (and since your bootloader is unlocked), then @fil3s suggestion to use the Android Flash Tool is the best option to try.

What were you trying to do, and at what point did this happen?
Is your phone recognized as a Android device, or is it showing up as something else?
Does holding down the Power button + Volume Down do anything?
