Guys-
In a quandry - I should have rooted a couple months ago as I now cannot get my Charge to recognize a USB connection with any computer. Computer recognizes something is trying to connect but computer gives me a USB Device Not Recognized message. It charges the phone when connected to the computer but doesn't ask me how I want to use the phone (as a mass storage device or media player) any more.
To make a long story short, I have tried everything - different USB cables, different USB ports, different computers, USB debug on and off, Ask on Connection and Mass Storage settings on and off. Have even gone thru several master resets of the phone and still will not recognize a computer connection.
Would love to root and hold on to this thing for at least a little longer, so my last thought is to ask if it's possible to root this device without a computer connection. From what I've read through on some forum threads it's possible with some phones, just want to know if using some of the methodology eslewhere on this site if anyone knows if its possible.
Thanks, in advance.
There are a few methods, like Framaroot, Z4Root, Gingerbreak (roots some Froyo devices also) and Universal AndRoot (outdated, but maybe works).

Hello fellow android-users. I have a problem. A problem that I can not figure out. My problem is the fact that no matter what I do I can't root my optimus v. I have tried literally everything and still can not root it. On the phone I've tried all known versions of Visionary, Z4root, easyroot, and universal androot. On the computer I've tried SuperOneClick but it always gets stuck on "waiting for device". I have searched so many forums and cannot find a solution. I think I could root it from the computer if it weren't for these bland general drivers I get installed on my computer every time I install drivers then plug my phone into the computer via usb. I have tried plugging it in to 3 different computers and always get these drivers. I have also tried 2 different usb to micro-usb cables (thinking that the one that came with the optimus might be charge only).Down below I have attached the drivers that always come up and what I think I should get (I screenshooted this from a youtube video).And all the lg android,virgin mobile, and usb drivers I have installed in various orders and mixed and matched but still no good. Also I have never had the phone get a usb notification when I plug it in.And yes I have Usb debugging turned on on the optimus. Although I have tried taking it off just for the heck of it.
Thank you for your time and consideration.
P.S. All i want to do is root it so that I can remove the bloatware and overclock it a bit.
Additional Information: Yes this is also posted on android central but I'm posting it here in hopes that maybe you all can help.
Additional Additional Information:I have tried every driver in every combination for the optimus v with never any luck.I have also installed linux on my computer If I will need that.Is there anyway to root it manually from the device itself, because that appears to be the only way. Here is a link to the official thread:forum(dot)androidcentral(dot)com/showthread.php?p=889790
If you try to connect via adb shell, does it successfully get you a "$" or "#"? Or does it say device not found?
This may seem odd, but try turning the phone off and doing the procedure for permanent root. Some have reported that turning the phone off fixes connectivity issues.
i rooted mine 2.2.2 with gingerbreak, very easy, install root and bobs your uncle
Try Gingerbreak..........works all the time
I downloaded the Gingerbreak v.1.2 app and when I press root I get "rooting....... running exploit..... This may take a few minutes! Device will reboot on success!" and I wait and nothing ever happens. And if yall are talking about the gingerbreak exploit on superoneclick I can't even get my computer to recoqnize my phone the right way.I've never had the usb notification thing pop up on the phone.I have downloaded every single driver for the phone and have installed and uninstalled them soooooo many times with no success.And I have had usb debugging on and tried rebooting several times with no luck. All i want to do is gain root acess to remove bloatware and overclock a bit.
Try all 3 versions of gingerbreak
Alright I already tried v.1.2,and 1.1, but it won't hurt to try 1.0.
remove any antivirus tht u have installed and try again
Alright I'll try that and get back to you
I tried it and it made no difference.Thanks for the suggestion though.
your sureshot is to downgrade ur device to froyo2.2. and then perform the root
Did u enable usb debugging mode? oO
josinpaul: My device is already froyo.The optimus v comes with froyo and I have not touched the OS. Also, how I would I do that if no computer can even recognize the device? (Not trying to be a jerk, just wondering if you could change the OS without being connected to the computer.)
ccdreadcc: Yes I have usb debugging on.And yes I have tried rebooting while I had usb debugging on and while it was connected to the computer via usb with no different results.
Keep your memory card unmounted ,I think here is the problem.

If you mean go to settings in the phone and unmount it then I already did that and it didn't make a difference.If you mean don't mount the sdcard when the usb notification comes up on your phone, then I have no choice.I can't get my phone to even get that (the usb notification).It's charge only when I plug it up to my computer and I have installed all of the drivers and tried everything (and yes a million times, I have usb debugging turned on).That's the whole point! I can't get the drivers to recognize the phone.I have tried it on 3 computers with 2 different micro-usb cords with never any success.
I wonder if your phone really is in USB debuging mode despite what it says. Here is a program to verify that you have rooted your phone. Gingerbreak should work on all firmware/android versions. What android version are you on? Many of the methods do not work on 2.2.1 or 2.2.2. If you go to settings/about phone you should see what you are running.
PS When you did Gingerbreak, was the APK installed on the phone or the SD card? Gingerbreak is mentioned in a number of threads. Have you check this thread? http://forum.xda-developers.com/showthread.php?p=13086954

I am not rooted.That's what I'm trying to do.I checked my version and it is 2.2.1.And i have always tried running gingerbreak from my phone, but it just says "rooting" forever.
Upgrade to 2.2.2 and give it a shot?
Or jst try after a hard reset o)
How would I upgrade it to 2.2.2 if i can't connect it to my computer?
Please take the time to read this:I flashed and installed SkyRaider a couple days ago and I noticed when I connected to my PC that my PC started recognizing it as HTC Phone (or something of the like). This apparently really screwed up my drivers on my computer because I installed iKReaM and now I can't even get into disk drive mode...it doesn't ask what connection type I want anymore and my computer just says "USB Device Not Recognized". I tried uninstalling the HTC Driver Installer but that didn't do anything either. This is not good as I ran into the same problem when trying to root my friends Samsung Fascinate and never go the problem fixed. Anyways...my phone worked perfect before and SkyRaider evidently messed it up pretty good...to say I am pissed is an understatement. If you need any more info please let me know.
Please link me to the newest HTC Drivers as well, it would be much appreciated.
If no one can help I will have to do a clean install of windows 7, which is not an enjoyable experience

You will have to buy the pro version to push files. That would be your easy solution.
You can always use recovery to get into usb mode as well.

I can't get into recovery anymore using usb mode, computer doesn't recognize the device so no way to use it...and I would use the Wifi app instead of using a usb cable? I see what you mean by easy but I don't wanna avoid the problem...I have a brand new $1600 Alienware so I would like to have it fixed lol...if need be I may just have to do a clean install
I know this isn't your actual problem but just for the record, AirDroid lets you control your phone and push files to it with a web browser and wifi for free.
(I tried linking it but I guess I haven't made enough posts to include links yet, easy to find by searching the Market tho)
You might check under Settings/ Connect to PC to make sure the Ask Me option is turned on.

When you plug your phone into your computer does the phone start to charge?
If so restart the computer and plug the phone into a different usb port. Check device manager and see if you have it listed in your usb devices, or you have an ! over a usb. Most of the time this ends up being an issue with the computer it is being hooked to, not the phone. The computer isn't launching the driver correctly to show the phone that it is connected to a computer, and not just a wall outlet.
Even when I've had this issue, which is random I have still been able to use recovery usb to manage it. Make sure when your in recovery you mount the sdcard before enabling the usb.
I have a rooted stock ICS SGS2. Since a couple of weeks my USB connection on my laptop isn't working anymore. When I connect the SGS2 to USB, nothing happens on the phone and nothing happens on the laptop.
No "unknown device", no "USB connection" beep, no USB connection on the phone.
I tried a differtent cable, didnt work. I tried on another PC, didnt work.
I change developer USB-settings (USB error check) but didnt work.
I searched a lot, but couldn't find any solution. Can anyone please help me?
P.S. Running on Windows 7 64x Professional

does your phone charge when conneted to the computer, you do not need drivers for that. If it does not try cleaning the usb port on your phone, there maybe dust or something stopping the cable from making ful contact.
Hi,
I had a similar problem ,
1-first try to check in parmater section -> stockage if usb debugging is on
2-Second try to reinstall kies for drivers
3-> change cable or clean your usb port with a toothbruch (slightely hhhh)
4-> if nothing of these solutions works and you get an unknow device also with odin that means youre usb port is broken, it simple to change and dont cost a lot (170 MAD for me ).
There are other threads that spoke about the same problem.Hope it works
My phone charges when connected. I also tried re-installing Kies and cleaned the phone port. Nothing helped
As mentioned before, i tried lots of USB ports, also other PC's and other cables. Still not working.
Any clue?
If you've tried 'everything', then it's a hardware issue. Unroot it, reset the flash counter, send it in for warranty service.
Hi,
i have a strange problem with my S2. i can get a connection with kies and myphoneexplorer. all works fine. but when i put my phone into download mode (usb debugging on, all tasks of kies killed) it says "unknown device". i tried several reinstallations of kies and drivers. i changed my usb cable. i used two other computers. nothing worked.
there is one thing, when i connect with usb, it says it is possible to get a faster connection (somehow i cannot use usb 2.0???). i transfer data with 700kb/s (i think this is to slow?) but my computer works fine with other usb tools (extern hdd works with 25mb/s). maybe the usb port of my phone is broken? but it charges and as i said i can get a connection in normal mode and transfer data. i
so help me out here
There's some help on this thread:
http://forum.xda-developers.com/showthread.php?t=1600497
Searching helps!
well, i am not that stupid, of course i found some threads with a similiar problem. but the solutions (clean usb port or connect through kies first etc.) ain't helping for me ...
Replace USB board/port. Search for KeithRoss39's guide in General section; has all the info you need, quick/easy/cheap (<AUD$10 for me) to do yourself.
i am gonna try that
but normal mode is working and charging too, so i guess it won't be the usb port.
but to rule it out, i will do it :good:
You'll often see some things will work/some won't when the board is on the fritz, they don't always die completely.
thanks,
that worked i could finally install the needed drivers in download mode :cyclops:
No worries. Glad you got it sorted
Good Morning Ladies and Gents;
I am working with an LG G4 H811 (T-Mobile) on 20v (MM 6.0), which I would like to root. I have unlocked the bootloader, which is confirmed every time I start the phone. I then tried to root using LGUP, but the phone wasn't recognized, so I did an error recovery reinstall in LG Bridge, thinking a fresh software install would re-align things.
Now, whenever I connect the phone to the computer, I get a pop-up window on the phone saying "USB Connection - Allow this computer to access your phone data?" CANCEL/ALLOW and the phone does not show up on the PC screen or in Device Drivers until I tap "ALLOW". Therefore, it is not recognized by any software without tapping ALLOW.
More than an inconvenience, this effectively prevents me from any mods on the phone, because I need to shut off the phone and disconnect from the USB port, then reconnect with Volume UP pressed to get to download, and in download mode I have no access to ALLOW the USB connection, so neither ADB nor FastBoot recognize any devices, and the phone is not included in Device Manager.
Of course, the bootloader is unlocked, Developer Options enabled, OEM Unlock on, USB Debugging on. I am using an original LG USB cable. I have tried 4 different computers and three different sets of drivers. I've tried older drivers on older and newer computers, and vice-versa, for every combination available. Each time, I plug in the phone after a fresh computer install and let it install it's own drivers. Two of the computers are Windows 7, two are Windows 10. I've tried connecting in MTP mode and PTP mode, with no difference. I've removed the SD card in case it was affecting things, and done a factory reset on the phone. Auto Play options have been set on the PC to "Do Nothing". I've searched the internet and this forum without results.
Basically, I've spent two days on this before asking for help. Has anyone else had this experience and solved it with something other than drivers? I think I've just about run out of ideas! Thanks.
I don't root however it's probably Developer options>usb default settings>usb tethering
Try connecting directly from Disk Management on the PC. Use the scan for new drives option if it's not visible.
Thanks buddy, appreciate you trying to help out.
Tethering is a way to allow a device connected to your phone to use the phone's data connections. In the tethering instructions:
"You may not be able to access the data files stored in the phone's memory, such as pictures, music etc, or transfer such files between your phone and your PC when USB tethering is on"
However, its worth a try - so I set up tethering, unplugged the phone and plugged it in again - the same Cancel/Allow screen came up, and no device in DM until I tapped Allow.
I then opened Disk Management and plugged in the phone. I still get the Cancel/Allow screen, and rescanning devices didn't show anything new, because the phone is not in the Device Manager until I tap Allow.
The key here is finding out why the phone or computer do not store the "Allow" command. Normally, the phone will show this screen the first time you plug it into a computer, and when you tap Allow, it will store that someplace such that the phone and computer are recognized as safe devices. You should never have to see the permission screen again. My challenge is that I don't know where that permission is stored - is it on the phone, the computer, attached to the driver? Don't know. And I don't know why it's not being saved. If I had those answers, I could probably edit the registry (or whatever) to make this a permanent attachment.
Thanks!
You're welcome.
Maybe debug mode?
Try turning off Developer options.
Obviously there is a way, sorry but I never had to use that function.
Try some Google searches which is how I usually find answers and/or by just playing with it
Well, I wouldn't be able to communicate via ADB with Developer Options off. And I spent two days searching the internet before coming here, and all I found was people updating their drivers, which is why I tried so many combinations of Windows versions and drivers versions.
I'm actually kind of surprised that this seems to be such a unique problem, I was hoping someone would notice the post who had actually had a similar problem and fixed it. But I do appreciate you trying to help!
Sorry I can't help, but I never choose to root.
It's time sucking black holes like this that I deliberately want to avoid.
At least you didn't brick it...
ha ha... you got that exactly right! Every time I do this I end up spending DAYS trying to get up to date on everything that has changed since my last phone!
Well, I appreciate you taking time to try to help.
