Hi, I couldn't find a solution to this so I'm making a new thread.
I'm having an issue when I connect my phone to my PC and USB debugging is on. I flashed openOptimus a few days ago on my phone (succesfully doing all the required steps including upgrading baseband). Basically, the phone shows LG logo screen like when it is turning on and then restarts itself. This only happens when USb debugging is on.
Anyone have any ideas why this is happening and how can I fix it?
Anyone has a clue?
I flashed again and usb debugging was not causing any trouble. The I tried to open QtADB with the phone plugged and the issue reappeared.

So when i try to connect my galaxy to the computer nothing happens. i plug it in and it will start to charge but the phone will not have recognized the fact that it is connected to the computer and the computer doesnt even say "unrecognized device" how do i get the phone and omputer to recognize each other?
Did you install drivers for the phone? What operating system are you on?
yes i have. ive tried both osx and windows 7 and i have made sure to download teh drivers for each
Have you tried to connect it in usb debugging mode? (goto settings, applications, devlopment, check debugging mode?
(I dont know of it will help, but it would be the next thing I would try)
And try different usb ports. I have heard before that it can help.
yeah ive tried all of that it and still nothing, the switching usb ports too
Did you restart the computer after you installed drivers?
I would try installing Samsung Kies (from samsung website, GS2 support page). It also installs drivers and fixed a problem I had with connection.
If all these don't work, I don't know what to tell you. Sorry. I am sure someone here with more experience will be able to help.
yeah haha ive done all of these unfortunately and still nothing, thank you for you suggestions though
Kies had an update within the hour of New years (Pacific).
I discovered this morning that USB debugging mode MUST BE OFF for Kies to recognize and connect to the phone. I'm currently backing up my device in this mode right now.
"Kies Air" also works well, without having to worry about any USB issues.
"Droid Explorer" connects fine with debugging turned on. I have to wait until backup is complete to see if it works with debugging turned off.
I'm having USB port issues right now, so your mileage may vary.
Hope this helps.
I have been running on Cooks I777UCMD8 rom for about 2 months now and have had multiple powering issues. Have tried all the basic trouble shooting, not sure if its the Rom causing the issues or the AJK noswap Kernel, but nothing has been tweaked, running as is. The booting issue is when connecting a USB cable while the phone is powered off, if you try to turn the phone on while the USB cable is still attached you get a POWER RESET OR UNKNOWN UPLOAD MODE error message, only way to avoid it is to remove the usb cable and hold power button then it powers up normally.
now the problem with the USB cable, and i feel these two are possibly related, my phone no longer recognizes when its attached to a computer usb hub, it charges, but dose not enter into mass storage mode, nor does the computer recognize that the phone is attached, i have tried on multiple computers with same results, and yes all drivers are downloaded on computers. Further information; Before this problem began accruing, I would get error messages after attaching the phone to a pc VIA usb cable saying ( ONE OF THE USB DEVICES ATTACHED TO THIS COMPUTER HAVE MALFUNCTIONED, AND WINDOWS DOES NOT RECOGNIZE IT ) also, after plugging in the usb cable and windows attempted to download the drivers this error also appeared ( DEVICE SOFTWARE WAS NOT SUCCESSFULLY INSTALLED, CONSULT WITH YOUR DEVICE MANUFACTURER FOR ASSISTANCE ) it later resolved itself for a short time ( couple days ) but now when i connect the phone, nothing happens... i'm hoping somebody has had similar USB problems after flashing a new rom and knows whats going on.
additional information:
- i have two Galaxy S2 phones both running cooks-i777ucmd8 rom and both phones have had the exact same issues.
- previous problems also include boot looping, and frozen lock screen upon powering up the phone. has not happen in a while.
Hi, first post here.. so Hi
I have an issue with my S3, i can't get my pc to detect it in download mode at all, no reaction from windows.. if didnt plug it in to the pc at all, it worked once, and it took me reinstalling drivers for hours to get it working, this is when i first rooted the phone using the cf-root method..
When i wanted to install a custom rom a few months ago i discovered it went back to not getting detected and has stayed that way
it's as if i've not connected it to the pc at all, i'm using a rear usb port, with the original cable, below is a short list of what i've tried
Tried 3 different cables
Used a brand new install of windows 7 with SP1
tried various Samsung ADB Drivers
Tried every single USB port, front and back on my pc
Used as many different USB Debugging options as possible
I noticed that when i turn on USB debugging after enabling developer mode, nothing changes on the pc, if i remember rightly my S2 made windows install the adb driver when i turned USB debugging on..
Any help is appreciated with this, never had any of this happen with my S2 lol :/ i've been messing around on and off the last few months with it, thankfully there's Mobile Odin and also Nandroid backups for me to fall back on
Pulling the battery with the cable plugged in while my S3 was in download mode is what fixed this for me...
With the usb cable plugged into the PC but NOT the phone, go into download mode.
Connect cable to the phone, then pull the battery out.
Once windows detects the phone and installs drivers it's safe to put the battery back in.
Phone will be detected by Odin/ CyanogenMod installer and so on.
Why in hell having the battery in stops windows detecting the phone in download mode is beyond me.. unless samsung did it on purpose? lol..
Installed CM 11 using the above method and it went perfectly, but i do have to use the above method whenever i want to flash something using my pc, so it's more of a work around than a fix..
Fix was found on YouTube of all places! hope this helps anyone else
I have an LG L7 II Dual P715, and I was in 4.4.2 before, now I downgraded to Jellybean so that I'll be able to root it [I GOT THE KDZ FILE OF THE JB FIRMWARE FOR MY DEVICE FROM THIS LINK http://lg-phone-firmware.com/index.php?id_mod=21 ]. When I connected my phone to my laptop running windows 7 32-bit without turning on the USB Debugging yet and keep it in MTP connection, my phone got recognized immediately by the laptop (because i already had the drivers installed even before), but whenever I turn on the USB Debugging, when i connect it to my laptop, it just charges and it doesn't automatically enter the USB Connection Type where in i supposedly have to choose whether to use MTP connection or LG Software connection etc. unless I manually go to that section in the settings of the phone.
I have downloaded the driver of my phone. I even downloaded a universal driver of LG yet I still get the problem.
so basically, the problem is I CAN'T CONNECT MY PHONE TO MY LAPTOP IF IT'S IN A USB DEBUGGING MODE. I opened the Device Manager and I can't seem to find any trace of my device when it is in USB debugging mode Except if It is TURNED OFF.
What do you think is the problem with this? Is it my LG phone or the computer who has the problem? When I was in kitkat, I never experienced such issue, but when I flashed it back to JB, I cant rid of this problem anymore, PLEASE HELP, I badly want to connect my phone to the laptop while the USB Debugging is turned on.

If all you need is to root your device then you don't need USB debugging. You just need to use copy Framaroot's apk to your device and install it, and that you can do in MTP mode as well.

Never had similar problems with the USB drivers nor needed LG's tools, so can't help you there.

Hi people, I'm having issue that's driving me mad. With USB debugging turned off, USB to PC connection works fine, I can tether, access my files and all that. If I try to connect with USB debugging enabled however, the USB connection just fails over and over again leading to hundreds of auto play popups on my pc and the "du dun" sound playing every second. I've tried removing all the drivers and reinstalling them to no avail.
Can anyone tell me what the hell is going on? PC is running Win 7 x64 ultimate, phone is on latest official firmware. Thanks.
Have you tried SPflashtool?
