[Q] i9100 lost the USB connection - Galaxy S II Q&A, Help & Troubleshooting

suddenly i lost the usb connect with the pc. i cant use the usb mass storage. but previously there was no problem at all. now when i want to use the usb mass storage. i click "connect storage to pc" then plug in the usb cable. but after that nothing happened. the phone still showing "connect storage to pc". then i clicked it. it tells me to remove the cable... or just charging the phone. any advise on it? thank you so much.
PS. i am in vallianrom 2.4.2

This is so obvious that I'm sure you've already done it, but have you restarted your PC? If so, try it in a different USB port to rule out whether it's the PC or not.

i have tried to reboot my pc and my phone. tried on different usb port and even other pc. none of them can recognize my phone. very weird

I find in such cases a total removal of USB devices on that port followed by a removal of all Kies folders registry entries etc then reinstall works .

may i know how to perform a removal of all kies folders registry entries and then reinstall? thx

If it doesn't work on other PCs then it's more likely it's the phone that's the problem. If you have CWM or Titanium then I'd recommend doing a backup and doing a hard reset, just to see if it works after that.

Please use the Q&A Forum for questions Thanks

i have wiped out everything and install the rom again but still couldnt get it done.

Hi m8, I hate to say it, but I'm afraid that if by trying with another pc, the phone does not connect, you'll have to factory reset it. I had a similar problem and that was the only solution for me.

try:
settings - applications - development - untick usb debugging retick it and try again.

It's more likely to be a problem on your phone's usb...
I had this problem on my X10 and it would only charge but never connect to mass storage... The only solution was to send it to be serviced...
Meanwhile a good solution to transfer files to your phone is to use any wireless sync app.. Like sugarsync, dropbox or Awesome Drop.
I strongly recommend using Awesome Drop for small files... Just download the app on your phone, go to their website on your pc and simply drop the file on the designed space and it will be synced with ur phone...
Very fast and easy... I never connect my phone to my PC again for file transfer...
I wouldn't use it for large file transfers though... Even though I have successfully transfered a ROM (250mb), some people had problems transfering large files through Awesome Drop... I recommend dropbox or sugarsync for those...

Did you try a different usb port as well? I've never used kies, but its my understanding it comes with its own set of drivers. Did you install those? If not, give it a try. How its done though, I wouldn't know off the top of my head. On the other hand if you did install them, uninstall kies and/or the drivers, and other ones if you have them, reboot, and reinstall the drivers you knew to work the last time. Also try a different computer if you have access to one, and see if it works.
Edit: I just read through the thread again after having my morning coffee, and didn't see one item in particular mentioned. In your settings - applications - usb settings, are you set to mass storage mode?
Set usb settings to mass storage and tried but no luck

Phone Mounting
Not sure what ROM you are using but I had a similar issue. With stock Vibrant the phone would mount as two drives in both Windows and SUSE - no problems. After installing the Nero V5 ROM the other day I couldn't get the phone to mount as a drive in either SUSE or Windows. Both OSs could see the phone since tethering worked. After much searching in a few forums I couldn't get a clear answer about what was going on.
Turns out that in addition to the normal use of USB debugging mode I now had to turn on USB storage in the notification area. It always turned on automatically before and when plugging in a USB cable the notification said USB was connected but the drives weren't being automatically mounted. I think it is because the Nero ROM has built in tethering and you have to specifically select either tether of USSB mount after the cable is plugged in. I think this extra step that wasn't needed before (because tether wasn't a system option) is what is causing some of the problems. Just a guess but one that worked for me.
Even after selecting mass storage from the notification bar the drives are not appearing.
I am on stock froyo. Haven't been able to try in a different pc, will let u guys know after trying in a seperate pc.

This worked for me and it has worked do far.... go to settings, applications, USB settings, and enable Ask on connection.. then it asks select Kies... it usually took a couple of times but it always worked for me.
I had to go back to an older version of Kies to make it connect. Allow it to update the phone's firmware but not update Kies.

Try reloading Kies 1.5.3.10092_2 and be sure not to allow it to update itself automatically. This is the only way I have been able to get it to work with my Galaxy S (while running factory 2.1, rooted).
I just upgraded to the standard 2.2 (haven't rerooted yet) but haven't yet upgraded to a newer version of Kies to see if these changes to the phone will have any effect on this connection problem. Just like you, the phone seems to be detecting the connection properly, just Kies won't finish connecting.
DONT ENABLE OPTION ASK ON CONNECTION POUT IT ON MASS STORAGE , IF THIS DIDNT HELP AND YOU ARE NOT ON STOCK LAUNCHER LIKE TOUCH WIZ .....REINSTALL TOUCHWIZ AND RUN IT AS DEFAULT should help .
and if u are on 2.1 eclair u need touchwiz back to make yoooour phone discoverable by kies . hey .

I upgraded via kies only, the pc detected the phone that time without any hitch. After the upgrade I am having this issue.

[Q] HELP: How to recover lost data from Samsung Galaxy S2?

Hi everyone,
I am in some trouble. I have accidentally deleted all my photos from my Samsung Galaxy S2 before a couple of hours. They were stored in Camera folder of my phone Gallery. Plus I have deleted one hidden folder as well which contained my personal data (videos) which was very important.
I know I should have been more careful, but I cant help it now. I searched on internet about how can I recover my lost data, but didn't come to any conclusion. Now, you guys on this forum are my last hope to get my data back if I can.
Is there ANY way its possible to recover the data that I have deleted? Please let me know guys, I need your expertise to resolve this problem.
I am having Samsung Galaxy S2 [GT-I9100 model] [ Android version: 2.3.3]
Thanks a million...
Hi. I want to help you and I help how much as possible so.
I see somewhere can you search in Google: how to recover deleted photos/data on android ?

Hi Jokesy,
Thanks a lot for the link. I went through it, I installed that software as well. but the problem is that, the software shows ONLY my computer hard drive. it just doesn't show my mobile disk.
Means, I have connected my mobile through the USB cable. So it shows "connected" on my mobile screen. But that software just doesn't pick it up. I can restore the files that I have deleted from my PC but not from my mobile. I haven't kept the option for USB debugging ON, its OFF. But I am not sure if that has anything to do with this. Because when I tried with USB debugging: ON, it still doesn't show my mobile storage in the software console. I don't have any external SD card, I have lost my data from my PHONE memory, the one we get inbuilt [11GB].
Is there a way I can make the software detect my phone memory and try to restore my deleted data? Any help would be appreciated

You need to connect your phone as mass storage.
Enable USB debugging under application settings, then reconnect your phone again to your Pc

I did that, but for some reasons, its just not showing my mobile as external storage. It just shows me 2 new drives like Removable Disk H: and Removable Disk I:. But when I click on them it asks me to "please insert a disk into drive". So basically when I do the debugging: ON, my phone is not getting detected a a storage unit. But on the phone it says that "USB Connected, select the files to copy from your computer". But the photorec software, still doesn't pick it up.
Is there anything that I am missing? Attaching the snapshots... :crying:
Do you really know how to use your mobile phone?
When you connect your phone, open your notification drawer and turn on USB storage!

Got it now, I am so sorry. Stressed up
Will let you know how it goes...
Way to copy & paste from here (Yes it was that obvious the words weren't yours).
When you deleted something in your phone, first remember not to use your phone again, including text, calling,and try to recover the data you want first. After that, you may use you phone.
I also recommend using google drive and google+. All my photos and videos are there. 15 gigs on standard and if you download quickoffice on your device and link with google drive u will receive another 5 or 10 gigs. I presume 20 -25 Gb is more than enough. The best part ? A good wi-fi connection and google drive installed on the PC and phone and you can access your files anywhere. Add astro file manager for transfering files from internal memory to google drive and viceversa.

Have you gone to Google play store and done a search for "undelete".
I have accidentally deleted stuff in the past and this worked for me. I can't remember which on I used... Will search and edit it in. undeleter by fahrbot. I even shelled out for the premium version. So must have liked it.

Xperia Go could not use storage due to USB detected

Recently My phone suddenly could not do anything relate to the storage, I can not view album, it says there is nothing there, I can not find picture, can not take picture and post to Facebook or something, when i clicked into PhoTo in Facebook app , i got a pop up:
Your computer detected a USB cord and locked your phone for storage. Please disconnect the cord to see your photos
Click to expand...
Click to collapse
. And into Gallery it says found nothing .
All i guessing is my storage (sdcard and ext_card) have been locked because it detected a USB connection. I try alot of methods even wipe all date, install a new ROM.
It happened since i uninstall Mcafee antivirus by titanium backup ( or may be something else , just guessing ) I tried to reinstall it again and nothing happend, still locked.
I try to search the internet and may be i am the only one fooling around with this bug. Any idea please?
hey
Anyone Pleaseee!

USB and MTP problem

Hi everyone, i'm having an issue with my G5. I can't connect the smartphone to the PC with MTP mode, it only recharges. I tried to download and install drivers ( from the LG's website ) but the smartphone doesn't appear to the PC. What could i do?
is it in charging only mode?
if yes then go to Developer Options (if not enabled go to Settings > About phone > Software infor and tap Build number 5 times) and set your USB configuration to MTP

by chance, did you change the port from the PC?
also did you try to uninstall drivers and install again
on my Windows 10 all seems to have been installed automatically
Yes i tried with another port, but nothing. Now i'm trying to uninstall drivers, will let you know.
Uninstalled all the drivers, and tried to install from zero, but nothing.
Edit: tried to insert a micro-sd in the smartphone, but nothing displayed on the PC. i'm also having a strange problem with the microphone: i haven't problem while i'm in a call, but it doesn't work sometimes when i'm on skype, facebook or whatsapp

When I got my S4 a few years ago I couldn't get my PC to properly recognize it at all. Ended up installing "PDAnet for Android" (free version) which in turn took care of all the correct drivers or something, but after that it worked fine.
When I got the G5 last month I didn't have to do anything (PDAnet is still installed, but not running/active) - I simply plugged it in and it worked.
Might be worth a shot for you? It's a small app and doesn't do anything if you disable it from starting up when Windows starts

1 hour ago, i tried again to uninstall and install everything, and after some attempts it worked. When i unplugged it and plug it again, it didn't work. Took some other attempts and it worked again .-.

I found out a simple way through sheer luck. Might work if its not working or for those who are having these problems.
So I noticed that the MTP driver wasn't installed AFTER I fixed the problem. So, once you have your phone to "transfer files" go to "devices and printers" on your Windows and you should find your LG phone under "Unspecified". Right click and go to properties. Then go to the hardware tab and update your driver from there. Make sure to update via online. Worked for me
I had this same problem. I switched USB mode from MTP to PTP, and it solved it.
This source agrees that LG devices need to be set to PTP, unlike all other Android devices: recovery-android.com/fix-android-file-transfer-mac.html
BTW: Did someone recognize, that some files are missing if connected to pc?
I have copied "all" files from ext. sd-card of my G5 to an external drive.
But as i had compared ext. sd-card with an external sd-card reader, there is a big difference of file count!!
It was the same effect, after copying files between int. mem and ext. sd! Sometimes this files are also not visible if connected to pc!
Could someone explain it to me?
