I am in desperate need for a stock recovery.img for my LG-P509.
My stock android 2.2 was recognized by "LGMobile Support Tool" and updated to stock 2.2.2.
I rooted my phone with Gingerbreak, then i forgot to make a manual backup of my original recovery.img (thru a terminal emulator), then i installed a custom recovery (ClockworkMod 5.0.2.0 - Old BB), and then i did a full system backup.
Now my phone is no longer recognized thru usb by any computer so i can't run any computer based tools, I would want to flash an original firmware from LG thru the "LGMobile Support Tool" or "KDZ updater" (i already have an original "V10S_00.kdz" firmware from LG to restore everything), but the problem is i have no USB access.
I have installed, uninstalled, reinstalled the LG United Mobile Driver (USB Driver for Windows), LG Android Driver, LG USB WML Modem driver, LG SP Usb Driver Installed and LG Support Tool.
I've tried the different combinations of:
"USB Debugging" off, "Mass Storage Only" on with sd card
"USB Debugging" on, "Mass Storage Only" off without sd card
I did this on the win 7 machine that once recognized my phone, then i tried on another machine with win 7, then i tried on a fresh install of win 7 and none recognized the phone (about to try on a fresh xp instalation).
I tried "LGMDP-v1.5" and it also didn't recognize it.
The phone devices (either as a phone, lge modem or usb storage) do NOT show up on the device manager (either correctly installed or as a problem device).
The computers do not even make the usual peripheral sound when the phone gets pluggled in, but they do it with usb keys, mice, keyboards, etc.
The phone does recognize the usb connection because:
When plugged to the computer usb it starts charging and makes available the option "usb tethering" on the phone.
When plugged to an outlet with the same cable and a usb charger it starts charging but doesn't make available the option "usb tethering" (as expected).
I tried different cables and got the same result.
Tried reinstaling the USB hubs, tried rebooting with the phone plugged in, tried removing the WPD drivers (as per some threads online: wpdmtp.inf and .pnf)
I've installed different ROMS and been able to restore backups without issue; i feel like i've run out of options and hope that the original recovery.img gives an emergency option to be able to connect to a pc.
Any help would be greatly appreciated, i've been at this non-stop for 2 days and going insanely frustrated.
Boot into recovery, then connect phone to pc, then it will be detected and will install drivers itself

I had tried booting into recovery mode and plugging it in and nothing happened, tried the same with emergency mode, then tried both with the pc off and then turning it on. (i did this with the clockworkmod 5.0.2.0 recovery and with amon-ra 3.0.6 recovery). I thought the usb port itself may be damaged but it still charges and the phone does recognize the presence of usb data capability (because of making the option "usb tethering available).

i used different cables and pcs but still not recognised
yesterday i used odin with those options :
BL/AP/CP/CSC and checked
Auto-reboot
F.reset Time
phone EFS Clear
Phone bootloader update
it has taking some while to execute but after that my phone was working and detectable again by my pc the problem was resolved for a couple of hours, in the evening the problem occured again.
and i have tried the process again the same why but no connection at all.
i don't know if its a hardware problem or software related problem
because the usb work when i m in restore mode (Odin mode) otherwise no.
Its an advance problem i already check all about usb / cable and pcs related problem.
Problem resolved
I sent my S6 to Samsung SAV it take them 4 days.
they doesn't give me proper answers on what they have done but i saw that my mini-usb plug is new so i expect that they got this part changed accrodingly the samsung has no sign of damage its a clean operation.
Its now detectable. It was indeed a Hardware problem
i have the same issue but in a g928f
today i changer my lcd with the micro usb flex
so all is new except the main board and still is not recognised at any pc with any cable.
i am really starting to feel very sorry for this phone.
odin does not see it at all even at download mode.
i don't know what else to do.
Software or Hardware Issue
I have a s6 920t that I am suppose to pay for at the end of the day. I got it from a friend who bought it while overseas. The only time my computer detects it is in download mode/odin mode, I hear the sound and I see it as "Added". When I try to connect any other way I don't hear the sound my laptop makes when it has detected a new device also otg cables don't work. I just simply want to know if this a software or a hardware issue? Software I can fix but if it is hardware I don't want to waste my money. Please anyone reply as soon as you can so I can decide what to do.
Thank you
I have two S6 Edge and one of them started doing this (phone only appears on USB when in Download mode). When swapping the motherboard between the phones, it works. So the problem isn't with the motherboard, but the USB connection module attached with the ribbon cable... There must be a chip on the module which gets locked somehow and replacing the board is at least one way to fix it. Hopefully someone finds another method without replacing the charger board?
Hi,
I've had some problems with my N8010 recently. I reset it and am now finding that the laptop won't recognise USB (comes up as malfunctioned).
It's been rooted.
I can enter ODIN by pressing home and power up and can also access download / install customer OS by pressing home and power down (although it just sticks on "downloading").
Thinking it might be the USB (although the tablet was being charged when it was plugged in) I've tried a few but all have the same problem.
I've tried re-installing drivers via device manager, have tried the USB cable connection error in Kies (that goes very quickly through it's analysis and doesn't fix it).
Given I've done a complete re-set there are only the basic apps on the device (other than SuperSU - although I've done a full unroot).
Any other thoughts as I'm stuck and can't fix the issues.?
Settings:
GT-N8013 (although it is GT-N8010)
Android 4.4.2
Kernel - 3.0.101 Boeffla Kernal 3.0-beta6
Build - Gnabo.Rom.v8
Can anyone help?

USB not connected to a mainboard usb port .
Try a different PC .
When I plug in a my tmo galaxy s6 into my windows computer it says "The last USB device you connected has malfunctioned, and windows does not recognize it." The s6 charges fine but I can't get it to connect to my computer. I also tried a mac and it wouldn't give me any mounting options.
I was trying to unroot and return to stock using ODIN (which is something i've done before) but now I'm stuck in a bootloop and I can't get the computer to recognize the device. I've tried to do a factory reset from recovery but it still leads to a bootloop. Any ideas??
Any help please?....
Hi all
I've had a soft bricked device now for 4 days I've read almost every post on the net to resolve this issue. So my Samsung S6 SM-G920F is stuck on the blue screen saying "An error has occurred while updating the device software. Use the emergency recovery function in the smart switch PC software." I can get into download mode 'recovery' however my phone will not connect to my computer via usb. With an error message stating "usb device not recognised. The last usb device you connected to this computer malfunctioned and Windows does not recognise it.
I have tried:
Changing cables
Changing computer
Deleting drives - rebooting comp to reinstall
Removing kies
Removing smart switch
Reinstalling smart switch
Reinstalling sub drivers
Editing power options and disabling USB ports
Entered HP BIOS and ran a port check which did however result in failure but then same situation on another HP laptop with working ports.
The device is charging when plugged in but not available to flash and reboot/bootloop.
If anyone has a resolution I will be eternally grateful.
Thanks in advance
