Hi mates,
since this evening, my Galaxy S2 (unbranded, unrooted, with stock firmware) was connecting fine with my PC in the "kies mode". I could use kies flawlessy, and I could regularly see my phone in my windows 7 (x86) explorer, and use explorer to read and write files from and to its memory.
Then, this evening, I got a notification, from kies, that an update (of kies) was available (2.0.2.11071.182.2), and I gave my consent to the updater. It did all its dirty job but after the installation of the new version, despite the phone connects via USB, every time I try to access the phone's memory from the PC, the connection drops. It restores backafer one second or two, but then again, if I try to access the phone's memory, it drops agains. The problem appears indifferently when accessing phone's memory from kies, and when doing it from windows' explorer, and this makes me suspect of the drivers, that the new version of kies brought along.
The phone connects correctly to the PC in the direct USB mode, and I can access its memory with no problem, and this also suggests that the problem should be the drivers.
So I uninstalled everything (new kies and drivers), and rebooted the PC, then I dowloaded what I believe is the previous version of kies: 2.0.1.11053.99.3, and launched its installation. After the end of the process, I rebooted the PC, just to be safe. According to the list of the installed software in my PC (in "Control Panel > Uninstall a program"), the drivers have rolled back, as expected, to version 1.3.2410.0 (before they were 1.4.something).
At the first connection of the phone to the PC after the reboot, I got notification from windows that the device installed correctly and it is ready to use (all the tree drivers are indeed reported as installed correctly)...
The point is that all this did not solve the problem at all, and USB connection still behaves exactly as badly as before.
I tried again uninstalling and reinstalling everything, also adding a manual clean up of the windows' registry from any entry related to "samsung", checking that the phone was not set in "USB debugging" mode, and disabling the antivirus, but despite everything appears to be fine, the phone regularly keeps on refusing to maintain USB connection alive everytime I try to access its memory.
What drives me mad is the fact that until this evening, everything was working flawlessly!
What else can I try????
I've just made a test on another PC running windows XP, with latest Kies 2.0.2.11071_128 installed. It's my office PC, and although I'm not 100% sure, I seem to remember that, until yesterday, my phone was connecting fine with it, and with that version of kies. But now, all of a sudden, I have the same problem also with this PC...
So, likely, it is a problem of the phone... the MTP application restarts everytime I try to access the phone from the PC, so... what can I try on the phone, to see if I can fix this annoying issue? I DON'T WANT TO FACTORY RESET MY PHONE, PLEASE!!!!
If any of you has any suggestion, I would be more than grateful...

I had the same problem the other day and I could not find a way to fix it, in the end I did a factory reset from Settings/Privacy and its ok now, just wiping cache did not fix it, factory reset was needed.
Dear Odia, thank you very much for replying and giving me a clue.
So... it appears that there's nothing else to do, is there? Buhahhaa!!! I want to cry!!!! I haven't made a backup and resetting the phone will be really painful... I'm already starting to feel the pain in my ass!!!
By chance, do you happen to know if I will have to buy again the apps I have already bought from the market? I have always kept both "Backup personal data" and "Automatic restore" ticked in "Settings>Privacy"... Could this be of any help?

You can always make a backup now before the reset and you will not have to buy paid apps again.
Yes but how can I backup my phone if kies will loose the connection with the phone as soon as it tries to access its memory?
Oh wait a moment, Perhaps I could use Kies air? Deos it allow to backup the phone? 'cause I can't test it now in my office, there's no wifi here...
From what I can tell, its the amount of the power that is supplied to the USB port itself that is the issue. I have the same problem when I put my i9100 on certain computers. Same thing happens to my WD MyPassport. Certain computers it works fine, and some it will power it for a bit, but once the device starts to draw too much current, it just disconnects.
This is why I try to do all my modding and flashing on a laptop, since, for me, they seem to be the most reliable in keeping devices powered up properly.
This is certainly a good point, but in my particular case, USB connection used to work up until yesterday with all the PCs I have (2 laptops and a desktop PC), whereas since yesterday, it works with none (with and without using the same USB ports). In addition if I use straight USB connection (hence not through the MTP app used by kies), it works fine.
Anyway what you have just mentioned is actually what scares me, because it would mean a hardware fault. But I'm crossing my fingers, hopefully it's (just) a software related issue and a factory reset will solve it. After all, straight connection works, so it would be really surprising if it were a hardware fault.
I will try resetting everything when I get home. Another "nice" busy evening to account to Samsung!
I guess if all samsung customers were honestly paid for every hour spent mending/fixing the issues of samsung products, the company would declare bankrupt in a matter of a few days!
Ok, I solved the issue with a drastic factory reset.
Thanks Odia for helping.
I spent 8 hours backing up and restoring everything included all the settings and personalisations. I went to bed at 3 am, eating only a quick sandwich in front of the bloody phone.
THANK YOU SAMSUNG, I wish to electrocute all your ****ing managers.
I hate when something in a device screws up all of a sudden and noboby knows why. It could happen again any time, and again I would have to spend hours mending a stupid phone instead of enjoying my life.
By the way, does anybody knows exactly what data is automatically backed up and restored on google servers by these functions?
"Settings>Privacy>Backup of personal data"
"Settings>Privacy>Automatic restore"
I always had both tiched, and I noticed that almost all the applications downloaded from the market that were installed on the phone, were automatically re-downloaded and restored on the phone at first boot after reset, but I'm not too shure I have understood what else was automatically restored.
I just read this thread for the first time, and was sympathetic to your issue when I started reading. I could see that there had been problems, but suggestions had been made and you seemed to be making good progress.
I was getting ready for offering advice and wishing you well with your problem.
Then suddenly you start to wish physical harm on Samsung employees.
Bye.

This is a simple solution try it and it will work for you the next time you face it most of the time it is a hardware issue i have been facing the same issue and nothing helped neither the factory reset nor the *#7284# procedure.
Take a pointy object like a pin or a paper and then clean your usb slot of the phone properly cuz most of the times usb pin points gets connected with each other due to the atmosphere and metal reaction. After that it will work like a charm for you. Before commenting anything negative i would appreciate if those who are facing this issue for a long time try this and then comment
Had the same problem, solved it by upgrading the phone software.
Setting > About Phone > Software update.
No need to afraid losing files. Hope that helps.
i faced the same problem on the GalaxyS sometime back. i did factory reset too. I got the same problem again. but i remembered it working on my LG TV so i did not go for factory reset. I went for re-install of samsung's USB driver for Windows. now it is working fine.
I fully agree that Samsung needs to be more responsible and responsive in resolving the such problems without causing data losses.

You could have saved a lot of hassle by installing a custom Rom and Kernel. I hate MTP mode! Mass storage mode is much better, I never had any problems with that....
Workaround - Power Management
This may be fixed, for now. However, in the future, there is a small workaround that you can use so that you're not required to wipe your phone every time this happens.
Here's what I do:
Since the device's connection is severed after the use of a certain amount of power, we can control the power management of the port that the device is connected to.
On WinXP:
Enter "Control Panel" > "System"
Click on "Hardware"
Click on "Device Manager"
Find the "Universal Serial Bus Controllers" section
Click the "+" next to that, and find the "USB Root Hub" that the device is connected to.
Right-click on the Hub, then select "Properties"
Click on the "Power Management" tab
Then, UNcheck the box that says "Allow the computer to turn off this device to save power."
This will prevent the connection from resetting. It's a quick workaround that works pretty well for me.
However, I ought to note that the changes should be undone after you're done with syncing the device, ESPECIALLY if you're on a laptop. Otherwise, you could risk a lot of battery/power usage within a short time, even if there is no device connected to that port.
Good luck, I hope this helps.
Cheers!

Please don't bail out because of that comment, i have been having this issue for a month and AT&T almost sold me another phone telling me it was the USB PORT.
I changed my phone setup dialing *#7284# and changed the UART to : PDA from Modem and same for USB (to PDA) modes. This helped get connected as before it would not even recognize the phone (computer would not do so).
I was am not sure if it is not the battery or charging circuitry, as others also reported, but my charging circuit is working fine and my battery charges 100% and last all day as normal. I can connect to the USB port and see my phone for a short while but it will suddenly disconnect.
But same as before it suddenly disconnects and will reconnect cycling continuously. I also believe it is the charge circuit because when it is charging, i hear the phone constanlty beeping from turning the schreen on/off. Same as when it is plugged into the usb port on computer.
Am tempted to buy a battery, but is can run the phone on the USB port without a battery in the phone. Problem continues without a battery...disconnecting and connecting to the computer.

I was plagued with this same problem, until I tried the above fix, and it works brilliantly! No more disconnects, great stuff.
It's pretty old topic but maybe someone has same issue and doesn't want to loose data. I had similar problem (couldn't connect to device, also couldn't install/uninstall any stuff because of no-space-available error).
I managed to download all pictures/documents via adb - worked pretty well. A sample command to retrieve all camera pictures:
adb pull /mnt/sdcard/DCIM
Hi, everyone. I've seen the other threads and no one had a problem quite like mine.
Yesterday I've upgraded my Alcatel OT-997, ICS 4.0.4. with Kuano's TWRP and now it's:
Alcatel OT-997D, JB 4.1.1. - (details in this thread, 5th post) http://forum.xda-developers.com/showthread.php?t=1981692&page=89
D means I can now use two SIM cards, which is cool.
The problem is the damn thing doesn't charge when it's turned on. It shows the lightning bolt over the battery icon, but in settings shows that charger is not connected. However, when it's turned off it charges, normally. I tried different settings in USB menu: Mass storage, MTP, Camera mode and Charge. Tried with and without Debugging mode. All of those work when connected to a computer in the sense that I can use internal storage, access both SD cards, and so on. But it doesn't charge.
I have tried 3 different cables, 3 wall outlets, and 2 PCs so it's not that. I suppose it's not a hardware problem otherwise it wouldn't charge properly when it's turned off.
So now I use schedule to turn it off before I go to sleep, and to turn on before I wake up, so it would charge while I'm sleeping. Anyone's got any ideas how to fix it?
Bump
Well I solved it with reinstall
Finally I've lost my patience so I tried the only thing that was left.
First I did a backup with TWRP.
Then, factory reset from TWRP.
Then, restore system from One Touch Upgrade 2.8.0 - lost the DUAL capability, software restored to 4.0.4.
Now comes the interesting part. It had the same problem as before, did not charge while on. So I tried a solution I found online a while ago but I never tried when on 4.1.1: Turn it off, connect charger, remove battery, wait a bit, press power button for approx 10 sec (nothing hapens), wait a bit, instert battery, turn it on and there it is. I'm not sure if it was this procedure that did the trick or it simply needed a reboot after update but it worked. It showed "charging" in battery stats.
Finally, restore with TWRP as Kuano explained in his post. Mind you, when I did the restore it was connected to my PC all the time.
Now two things I you should know:
First, before I did all this I connected it to my PC while turned off i.e. (PC - ON, phone - OFF). I noticed this: it was constantly connecting and disconnecting (the "piano chord" notification was coming from the computer speakers every 5 sec) like I was pulling the cable in and out. That is all I know about this, I didn't have the nerves to work on it.
Second, now that it is restored and charging, when I connected it to PC it couldn't change USB setting from Charge to MTP. It reported an error something like "service stopped". This happened only once and I did not try to do it again, I just don't have the energy for any more problem fixing right now. It charges, and I use airdroid for file transfer, that is all I need for now. If and when I get around to take a look at it I'll post here if there's something interesting.
Hello to all genius mind.
I am writing here, to find a solution for my problem. I will start from beginning, to be as clear as possible.
This summer, during my vacation time, while diving, I found SG J5 in the bottom of the lake (sorry for the person who lost it like that...). Since I never had android smartphone in my hands before, I was wondering, can this device still work, since I have no idea how long it was under water and what can I learn from this process.
After opening it up, cleaning with 96% alcohol and drying it, devices finally showed some signs of life. Actually, almost everything was working, amazing...
Once I got this device running, I started to deal with software. Following some tutorials online, I was on the process to bypass RFP, but could not finish it, since I had other important matter to attend to. After I was back, and turned device on, for some reason, it booted into safe mode. I have been tried again SideSync method, but it was not working, since device did not reacted, after I plugged in to PC. Computer can recognize device and I can even browser the files in it. Weird thing is, that lower volume button stopped responding (I had theory that it could be jammed, once I removed it and cleaned contact, no changes was in the system, still in safe mode, so its not jammed button...), it was working before and all other buttons are working fine. Because of that, I cannot load recovery mode.
OTG method also did not worked, since nothing happen when I plunged usb into phone (safe mode block all external apps). I have tried to flash new ROM, with a help of "Samsung 300K Tool" I can launch download mode, but new ROM did not gave any result either, and RFP blocks all custom ROM's, that could modify system.
ADB do not find the device, since USB Debugging is probably off, and I don't know a way how to activate it from PC. The trick to disconnect WiFi, when it checks info for google account, did not worked either, since its not possible to select a text for sharing it.
After trying all the methods that I could find, I hit the brick wall. Phone works fine, but its completely locked. I am thinking, that new Samsung protection system is designed like this, to force phone in to safe mode after one hard reset and lock all posiblities to byass RFP, not sure though, it could be hardware problem to, but no idea where...
Does anyone here could help me out with this case
THANKS!
Best regards to all,
HG
I have my USB Config set to MTP and USB Debugging ON under Developer Options. However, whenever I connect a USB device, it always resets itself to Charge only and I have to switch it back to File or Photo transfer in order to connect to PC, AA, etc.
Any ideas on how to make the USB setting 'stick' with what I set in DO?
Is there an ADB command? Other setting I should be looking for? Any help is appreciated.

Strange, I *know* that mine 'used to' stay at whatever setting it was left at before. I just tried it now, and it still stays on whatever it was last set to, BUT... It automatically toggles the 'allow debugging over USB' to OFF every time I plug my phone into my computer. Now I know it didn't do this before, I wonder if it has something to do with 'always trust this connection' being set? Also, it really seems like this stuff is behaving just a wee bit different since I unlocked my bootloader. Hmm, could it be they have set a flag where USB debugging always turns off when the device is connected to something, IF the bootloader is unlocked?

I can confirm that this happens on mine too, really annoying, but I think this is not something a lot of people are facing, as there are literally NO other references to this that I can find. The reason why I think this is a very specific issue is that I recently got a Mate 20 X, which is essentially the same phone, and noticed that when I plug in the USB to a PC, I get a dialog pop up at the bottom of the screen asking if I want to transfer photos, files or to charge only. I NEVER saw this on the Mate 20 Pro, but that might be because I messed something up. I did do a lot of fiddling over ADB when the phone was new (mostly disabling apps) and giving permissions to apps like lightning launcher and System UI tuner and I'm wondering if this what has caused the issue.
Obviously even before I did this, I necessarily must have connected to the thing via USB, but strangely, I don't remember seeing this dialog... Having to go into developer mode to change this setting can't be how it's set up normally, as then basically no-one will be able to get connected via MTP (I suspect everyone on XDA knows about this setting, but suspect none of the average Joes even knows the option exists).
So the question is, what did we do wrong and how do we get this diaglog back because I have found that Developer mode is not accessible for other Users set up on the phone so I can't access the phone at all via USB now when the other user is using it...
I'm hoping we can work together to find out what we did wrong!
PS: I find like kaibosh99 that the USB debugging also toggles back to off. I am not rooted or bootloader unlocked
After a lot of faffing and looking into it some more, I don't get the pop-up dialog but have discovered that it is in the notification menu where it shows
USB icon . Charging via USB
Expanding that notification and tapping on it, gives the option to choose file transfer and a load of other stuff. It's a pity that a pop-up dialog doesn't open like on the Mate 20 X, you can see what I mean here

Much easier than having to go into the notification menu!
