Hi,
I'm having a real though time trying to connect my galaxy s1 to a pc. Have tried everything, like kies, direct connection, reseted the device, and no joy.
When I plug the cable it makes that sound as it is connecting but it doesn't show in the PC anywhere, nor even in Device manager.
It can get pwr from the usb cable when is connected; already tried with another cable and same thing.
My final goal is to unlock it.
thanks for any help

I guess yo mean Debugging mode, as I couldn't found Depurating anywhere. Have selected it and the same effect

#Samsung Kies always makes problems on Windows x64 !
##I would recommend, if you got 32-Bit Computer, to use that ;-)
#If you Want just flash over Odin, then is this driver package enough

Hi there.
By direct connection you mean the USB Mass Storage mode, right?
It might be some weird, random problem with the samsung system drivers. I used to have such problems about two years ago, back in the days of Froyo. Have you tried re-installing them? There was a link to proper drivers file in one ICS installation tutorial, and those drivers can be downloaded here. If you go about trying this method, lemme know if it worked.
Cheers.
PS: Unlike diklooc there suggested, do not never EVER go back to x86 OS. That's the worst advice. Kapisch?
Did you check your usb port in System ?
Sometimes it stuck with another lastest device
Hi,
have tried everything, and finally only in a WinXP32 could be abble to get the error shown on the file atached.
But nothing (warnings) come up in Device Manager
Unninstalled everything (kies) and tried to install only the driver and nothing happens.
Should I try to mount it on a linux?
or is it dead?
thanks
i have this problem too
wat chan I do???
my sgs can not connect to my PC
This may help...
Hi there - I don't have the same phone as you, but I did encounter the exact same problem. I've been searching around and it looks like the most common fix was to simply replace the cable. I don't know what kind of cable you have, but my phone (a Samsung Focus i917) uses a mini-usb connector. I found that my Amazon Kindle used the same connector.
When I was using the Samsung cable, I'd get intermittent connects and charge power. The OS would report unknown device. When I switched computer's = same result. I switched to my Kindle cable and the computer instantly recognized the device and installed the drivers. After 12 hours of troubleshooting, factory resetting my phone (blah - lost everything) it turned out to be the cable. I know that this isn't an easy troubleshooting step for most people, because who has an extra cable? I just got lucky that my Kindle uses the same connector. I'm now suspecting (due to the prevalence of this connectivity problem coming from people with Samsung phones - there are a LOT of reported issues) that there is probably a Samsung cable problem in general.
Good luck with your phone.

Nasdriver, I currently have a similar problem but mine is related with Samsung Kies as I can't get either my older SGS1 or my newer Samsung Nexus to get recognized by Kies. I also suspected the cable thing and even read it could be a USB port issue but neither of them was my problem (I have 3 cables and 8 ports on 2 computers that result in the same thing). I can connect other devices with the same cables and they work, so I suspect my problem is focused around the Samsung device drivers.
My advice is if you can go in a systematic manner, first focus on the cable (easiest to replace), if you get the same results with a new cable, then focus on the USB physical port, clean it with some Isopropyl alcohol, if the port works for other devices (camera, other phones, etc..) on the same cable but not with the SGS, then try reinstalling the samsung device drivers.
Oh, and if you want to unlock your phone, the EASY way is to download the Galaxy S Unlock application from the Android market (no affiliation) it's free (but the developer does accept donations) and it WORKS. I won't bore you with my 3 week journey trying to unlock my Bell SGS phone here in Canada, had I found this app first I would have done it in less then 2 min saved myself a LOT of frustration.
Good luck
Im aware that one or two other threads have been created with this same general question but one thing they didnt ask is what to do if you cant fix it?
As the thread topic states my Nexus 7 will not connect to my PC via USB (It is not seen at all, its not a driver issue I've tried). It will not charge when turned on but it was charging when turned off last night. When I checked this morning it said I had a full battery but after turning the tablet on it said I only had 60% battery. All the started happening after I charged it with a battery pack at work the other day because I forgot my charger at home (some people have had similar problems after using car chargers). It will let me connect a flash drive to it via USB-OTG. I have tried 3 different cables on 2 different PCs (One running Windows 7 and the other running Windows 8). I really dont know where to go for help anymore as Ive spent the past 2-3 days googling like a mad man trying to find an answer and noone seems to have one.
I would love for someone to really help me out and get some steps that could fix this, however, if its not fixable how do I RMA it? I cant lock the bootloader and I cant flash a factory image.
You say it is not a driver issue, but your symptoms indicate it is. I would start over with the removal and re-installation of the proper drivers.

I've uninstalled them. Every time I go to manually install them the guides always say to find where the nexus is and my nexus never shows up. If it was drivers it would still charge when its on. So how can drivers cause the tablet not to charge from the ac adapter?
Try Wugfresh's program. I had issues w/o it.

Thats the toolkit I have installed. Its also the "guide" I am following when it comes to drivers. I tried to see if I could make the nexus connect to the pc while in fastboot and nothing happened then either. Everything he says to do involves the PC actually seeing the nexus :/
Ive changed it from mtp to ptp, toggled debugging, went to different back ups, flashed a new rom, etc etc. I really feel like Ive tried just about everything. Someone mentioned in one thread about some specific code in the nexus being wrong and possibly changing it could fix it but I do not know how I would go about doing that.
I also originally used the Wugfresh toolkit and had problems getting the drivers installed properly on Win7-64. Ultimately, I think I installed pda.net on my computer and on the N7 and was able to connect after that. Haven't had a problem connecting since. Re-read some of the Wugfresh posts about driver problems. You should be able to get it sorted out.

I sent you a PM but I really dont think this is an issue with drivers. I have been able to connect the N7 to my PC perfectly before the other day. Never a problem at all. Now I have uninstalled/reinstalled the drivers as best as I could (currently I have the samsung drivers because they are the only ones that will install without having to verify that the phone is connected via ADB and I had them left over from my Fiance's GNex so they have been here all along when the N7 was actually connecting).
The N7 is not connecting to the PC at all. It does not show up in device manager. You cannot make an ADB connection to it. It has already been rooted and it is running the latest version of Paranoid Android. On top of that the AC adapters will not charge the N7 while it is turned on. Its like the N7 turns away any usb connection other than a USB-OTG cable while it is on.
Also I really do appreciate the help. This has just been really frustrating for me.
Hello,
Since yesterday, I have exactly same issue with my Nexus 7 3g.
Everything is working perfectly but computer doesn't see Nexus at all (nothig works Bootloader, ADB, MTP,PTP).
Charging is fine (looks like), USB HDDs, pendrives are working as before.
Reinstaling drivers, changing to PTP, switchin on/off USB debugging didn't help.
Checked : other Nexus connects to the computer without problems, so its not drivers issue.
I assume it happened after Nexus was connected to my car charger.
Does anybody have solution/fix for that ?
Unfortunately my Nexus comes from USA, can I RMA it in Europe ?
I feel badly for everyone having these issues. I feel very lucky I'm not having them. It sounds as if the microusb port may have been altered/damaged by certain kinds of connections, like the battery pack or car charger. I don't know why this would happen and my own car charger (Moto oem for my Bionic) has worked fine on the N7. I did pick up the usb cable attached to my pc one day and created a static shock to the connector. Since then, that bank of 4 usb ports will not show either my N7 or bionic, but my usb mouse, keyboard, and printer work with them. The other bank still works, as does the pci port expansion card and my front ports. If I do have a glitch with the pc connection, I restart both the computer and the N7 and then it works. Sorry I don't have a solution.
I also assumed a damaged/fried USB post on the Nexus 7. There are 2 data lines and 2 power lines in the charging socket I think. If the power lines are damaged, usb otg may still be working. Its also tying in with the use of a power pack.

Have you tried switching between MTP and PTP and seeing if that works? If I used the PTP setting for the USB it shows up, I can then move files onto the PICTURE folder and once there move to another folder while using the Nexus.

Wow or strange should be more of the reply. I have done this before but it never worked. Thanks for the help. For anyone else needing help here is what I did. First opened the Nexus Tool Kit, then Full Driver Installation Guide, launched USBDeview, then - In particular look for devices with Vendor ID - "18d1" or... "04e8" - Simply right click these devices, and select the option to: - "Uninstall Selected Devices", final step unplugged the device and plugged it back in and it worked. Also MTP enabled USB Debug unchecked. Thanks again...
-AkWingnut
Tried this and haven't had any luck so far. I'm going to try pdanet or samsung drivers again later today and post results.

Bump!
I'm experiencing similar issues with my Nexus 5. This is the only thead I can find that has a similar problem. My Nexus 5 worked on SlimKat, I flashed stock L Preview, now my device won't charge when it is powered into the OS. Bootloader works fine and charges when turned off. I upgraded to 5.0 which came out today (Yay!) and the problem persists.
Have any of you lads or ladies had any updates?

If you have an unlocked bootloader use this tool to lock it: https://play.google.com/store/apps/details?id=net.segv11.bootunlocker
To unroot use the permanent unroot feature in SuperSU.
Order is important since the Bootloader tool requires root.

thanks. i installed the android sdk and java jdk but still have the problem. i believe the problem is with the phone 100%
my nexus always shows that it's charging on AC whenever plugged in. doesn't matter if it even is to AC or USB. the phone shows up as unrecognized device with a bang in the USB section of the device manager. on some computers it doesn't even show up.
i tried on my macbook pro and it doesn't even show up there but in every case, the phone charges.
wondering if there's a switch or toggle somewhere that will turn it on and get it working
i'm going to install a windows xp VM as a last ditch resort and see if it at least shows up there.

Make sure your device is on MTP and try an other data cable which has no missing/broken data wires inside.

yep it tried on mtp and ptp with 4 different cables. two original nexus 4 cables, one nexus 7 cable and a blackberry cable. they all work with my other nexus 4... just not this one.
the windows VM didn't work unfortunately.

That is strange, it should work with the Windows Virtual Machine.
Maybe it is to do with the standalone machine using it in the same time.

Same problem here. USB is not recognized using my Nexus 4 ( it used to be recognized on two PCs, but no longer), but another Nexus 4 connects perfectly. I can only charge a USB rate on chargers that used to charge at ac rate. I've tried everything, and more than mentioned in this thread.

Hi guys,
Seems that I've got the same trouble. Got my N4 (stock ROM, 4.2.2) a couple of weeks ago and everything was ok - connection as MTP, connection for debug and so on. But yesterday I connected it to my PC and found that the device indicates charging but not USB connexion. So I've tried to reboot PC and N4, tried other cables and 2 other PCs (my with Win8, and those with Win7 and Linux Mint if matters). Other devices are ok (Huawei Honor, N7, Milestone2).
The phone just doesn't detect USB connection - in both MTP and PTP. Then I tried to plug in wall charger and connect back again to USB. AND IT WORKED! The phone detected the connection so I was able to mount it and detect with adb. I thought that the problem was solved but when I connected it next time - same ****. This time nothing helps (most likely that there wasn't any casual relationship between wall charger connection and temporary fix...)
What options I've got now? Try to root the device and look into syslog to detect if it's a software issue or disassemble the device and try to find any defects on USB port?
Thank you,
Alex

I got mine to work by using a 2 into 1 usb plug. The kind that comes with portable CD writers. Once I got it working I reflashed stock 422 and the problem is gone. Turns out it was a bad flash from the previous owner.

Thanks for advice. During this day it worked properly twice - the phone just started detecting connection. No obvious reasons for that... I got a new device with stock 422 from amazon and haven't flashed or event rooted it. How do you think, should I try to flash it with official 4.2.2? Now I can say that it's most likely a software issue.

Tried it out - the result is the same. Now I can not even unlock the bootloader to reflash 422... Btw I didn't managed to find a 2into1 cable but checked if the same trick would work with USB hub with external power - it works really better. The device can detect the connection almost all the times and I can see it listed in adb devices and as a mounted storage. Though in fastboot mode this doesn't help. Device remains unrecognized.

well if you're getting a connection to the computer but not in fastboot, your drivers might just need removal/reinstallation.
once you get it going, reflash the stock 4.2.2 from google and see how it goes.
if that doesn't work and you can get it going, get it replaced by Google.
if you can, try it on a mac.. they don't need the drivers installed. just run it all from terminal.
Okay, I've managed to track down the issue...
Once I got it available for fastboot I've unlocked bootloader and then flashed with Cyanogen. The problem remained but I could get dmesg output for plug-in event. I've managed to get logs for problematic case (doesn't detect USB data connexion) and for correct behavior case (when Android detects USB data connection).
No sense to put the whole log pieces here just a brief quotes.
For correct case:
Code:
Avail curr from USB = 500
For incorrect case:
Code:
Avail curr from USB = 1500
USB module firmware tells the system that it has detected data-connection and enabled low-power mode (500mA). In this case Android initiates mtp and adb:
Code:
<6>[62539.001178] adb_open
<6>[62539.001269] mtp_bind_config
<6>[62539.001422] adb_bind_config
And in problematic case USB module firmware incorrectly indicates for the OS that there are only power-connection (5V/ground). I cant say exactly where the issue is but there are only two options - bug in USB module firmware or physical fault of connection (pins, bus or whatever else). Anyway I've to replace USB module or just go with it and use adb over network (the matter is that sending the device back to Amazon seller from my country would cost me 1/3 of the purchase total so I consider that just unreasonable).
Thanks to LG - for my money I got not only a box with device but also whole lotta fun =)
Hey all. Just got my Galaxy S4 today and I was loving everything about it until... right now. For some reason, the darn USB won't stay connected to the computer. It doesn't matter if it's simply plugged into the computer as an "installer" or as a media device. It'll constantly disconnect and reconnect itself, even when I'm not transferring any files.
It's not the my computer/USB ports, either, since I can transfer files between my HTC Thunderbolt and Nexus 7 fine. I've also tested 2 other USB cables and they all behave the same way.
Anyone know what's going on? Did I get a lemon?
No im in the same boat. Was trying ti connect in today. I reinstalled and un installed the drivers about 4 times. Tried un selecting usb debugging in developers menu. Installed kies and used the drivers from it still no good. Used 3 different usb leads. Phone will still charge from pc and even when im installing the drivers again and connect the phone it will say that your new device is ready to use but still cant access phone, it simply does not show up.
Wouldn mind was working 2 days ago fine. Same usb port and all. And the port is fine cause my old s3 still reads from the same port.

every thing ok with s3 but the problem only with s4
please we need help to solve this problem!
Same problem
I have also been dealing with this for a while now. I have Windows 7 64bit and I have reinstalled the drivers many times through Kies and manually. It seems like the problem is getting worse since initially I could do some file transfer through usb if i fiddled with the device (changing usb ports, unplugging it, etc). Now I am hard pressed to get it to show up on the computer through MTP at all.
This is quite annoying since I am developing an android app and I need a usb connection in order to test it. A fix would be awesome.
I just tested on my sister's laptop and it doesn't have this problem. I clicked around the phone, transferred a 10gb movie, and left it plugged in to see if there were any signs of disconnects. None whatsoever. Odd. Maybe Galaxy S4 just doesn't like something with our computers. This is quite annoying.
I have a fresh Windows 7 64-bit partition I installed the other day so I'll test it out on that and report the results later today.

I am already put fresh win 7 but still same problem..
im on xp(retro yeah ha ha) but just a pc i have for my phones and stuff. But i got it working again by flashing my firmware through odin and its back working. Im blaming when i rooted it that it broke but ill see if it happens again
edit: Can confirm pc is now picking up phone. I just flashed the most recent stock rom for my carrier through odin and as soon as it finished updating its prefect now. Might wait another while to root it now and wait for more devs to jump aboard for more roms

I'm on stock, no root.
Hi
I don't know if it may help but i noticed the usb doesn't work when the phone is locked.
I did check 'stay active while charging' in dev parameters and i never got disconnected again.

Tested it out on a fresh copy of Windows 7 and it still continuously disconnect. What gives?

Oops, missed your post. Unfortunately, it disconnects regardless of the phone's state.
My friend's S4 was doing the same thing on his desktop. Every time he would try to transfer pics the phone would disconnect after a few files.
I tried different things from reinstalling drivers to trying to only copy over a couple of files at a time, nothing worked.
Finally I plugged his phone into one of the back usb ports and transferred over 2gb with no problem and no disconnects since.
My guess is the S4 is a power hog and some usb ports just don't supply enough juice. Try plugging it in to a usb port that comes off a motherboard. Don't use the front ports or usb hubs. Hope this helps someone.

I've been trying all kinds of different combinations of USB leads, phone settings and ports all morning and was just about getting ready to start a new Olympic sport of S4 hurling when I came across this post and plugged my USB straight into the back of my machine and it finally works!! Thank you dirrtpoor for your input - a simple fix, but nevertheless it worked.:good:
I suppose it makes sense that a quad core 1.9Ghz phone would be a power hog.
It wouldn't work on my home PC whatever I tried. Front or back USB ports.
On my dads PC sometimes it would display OK and other times "usb device has malfunctioned" (didn't try the rear USB port)
On my work PC it works fine on the rear ports.
I was having the same problem a few days ago, but then I reformatted the SD card, now everything seems OK.
Even the stock gallery app works now...?!
Guys I was having the same problem. For the life of me I couldn't figure out why suddenly my S4 wasn't being recognized by my computer. I finally went into developer options and noticed a "USB Debugging - Debugging mode launches when USB is connected" was turned on. I de-selected that, connected my phone and now my computer recognizes it again. I hope that helps guys, it helped me.

This may be laughably obvious but I'm a former Apple user, which has it's own dedicated USB connector, so I forget sometimes with the Samsung S4, which has a standard (looking) micro USB connector that I need a USB cable that is enabled for syncing as well as charging...not all USB cords with micro connectors on the phone end will carry the data because I imagine Samsung has made their phone's connector require a different wiring in the cable.
I was pulling my hair out yesterday trying to figure out why the computer wouldn't see the phone..then looked at the USB cable and realized I'd plugged a non-syncing cable in. I tried the cable that came with the phone and bingo, worked like it was supposed to.
Hope this helps, sometimes it's the little things we overlook that drive us nuts.
Any way to connect in master storage with out root.

Use a different usb cable and usb port. I know it sounds stupid but there has definitely been phantom problems which were solved this way, even with something as simple as adb commands
i have same problem. trying all the way but always with the same result...
Hello guys and girls, im wondering if there is anyone in the know of what i want to try and attempt. Firstly, i have an old Galaxy S4 i9505, it was my old contract mobile which was put in a draw and forgot about as the LCD smashed and i upgraded anyway. I recently went out and purchased an Amazon firestick for the sole use of KODI, and it works fine (i would like to auto boot straight to KODI or even do away with the amazon operating system all together but ill save that for a future post). My questions are..
1. I have currently got the S4 with the smashed screen rooted, on a custom Rom, (OMEGA v21.1) usb debugging enabled and with a nifty program called Vysor i can connect it to my laptop and browse through the phone and add/remove install what i like. I obviously need usb debugging enabled to see the phone through my laptop but cant see how i could install another rom without seeing the custom recovery on my pc (as it only lets me see and use the phone when its fully booted up) Id like to use this phone purely as a media device linked to my TV with an MHL v2.0 adapter (which i have and works fine with an exception).
So first question, is there anyway of installing a Tablet type rom onto this phone without seeing the recovery menu (doing it blind is out of the question as the touch is also broke) but the rom i install (preferably with gaaps with it) as i need no function of a mobile whatsoever, only wifi and bluetooth i guess, but id need it to have usb debugging automatically enabled or enabled in the rom i flash as id have no way to access the phone because of the screen. any help on this would be a great help.
Now onto my second question..
2. While MHL works fine and i can use KODI ok from my S4, there is a massive problem i need to overcome, the battery drains faster than the charge gives, my understanding is that while the S4 is connected to an MHL lead it will only draw 500ma of power as its recognised as an USB device. So my thoughts are: as a fully charged LI ION battery on the S4 is around 4.3 volts with amp drawing what the phone needs (actual phone rated at 3.8v so at a guess a supply of 3.3v-4.3v is perfectly fine, im wondering if a voltage drop device (from 5v to 3.8) soldered straight onto the battery pins on the phone would keep the phone going without any type of drain, as in it would power the phone inevetably while runnin kodi or whatever else i decide to run on it, ive scoured the net for info on my project but cant seem to get any info about it. i really appreciate any help whatsoever as im quite stuck at the moment. Thanks.

1. I still don't understand why you want to flash a different rom. What will be the difference? There is to much risk imo. You will need a rom with usb debugging enabled by default and rsa security set off. Why not just find a different launcher that will suite your needs? But if you still want then make sure you have TWRP on your phone and use something to control TWRP from the playstore.
2. You need to find a kernel that supports usb fast charge. That will boost your charging to around 1000ma.

First thanks for the reply Lennyz1988, the only reason I wanted another rom flashed was is im in no way going to be using it as a phone, so would rather have a rom that is very light and very light on battery (as in background proceses). As for a custom kernel would that have to be also flashed through recovery ? As I've not flashed custom kernels im not sure on how to go about it, will any custom kernel work ? Sorry for the questions but is there any chance you can point.me in the direction of 1 I'd need ? Thanks.
