[Q] Could use some help involving missing drivers. - LG Optimus L9 P760, P765, P768, P769

So here's a idiotic move I made while trying to unroot my T Mobile P76920h L9 phone. I tried one thread on here but it wasn't working so great. There was an error I was having so I took that error to Google and found some people who had the same issue. Their solution was something that I believe is what caused my now problem. Their solution was in C:\ProgramData\LGMOBILEAX to delete all that and replace with some exact same files.
Pretty much after that, everytime I plug my cell phone into the my laptop (Win8, Toshiba) my phone isn't recognized in the Device Manager usb ports. I tried downloading drivers and nothing is working. I can't proceed with my original unrooting goal and now I'm at a wall. Please anybody know if there's a solution? I'm thinking just deleting all LG from my laptop and downloading drivers again would be a solution, just have no clue if it is actually.
Thanks

Galaxy S2 Driver issue, unable to restore to stock.

I have a galaxy S2 which I've updated via XDA to 2.3.6, everything was working fine until a few days ago, I plugged the phone into my PC and I was given "One of the USB Devices attached to this computer has malfunctioned et etc" and then "Device Drive not installed correctly" something along those lines.
I've tried it on other machines and the same thing happens, I can't access the storage nor detect it in odin or keis.
Any suggestions or help would be hugely appreciated.
Bump for bumpsake
Try the first part of this thread (The bit about uninstalling/reinstaling Kies/drivers).
Can you let me know what happens? I had exactly the same issue but its in warranty repair, I would like to try to fix it when it comes back, Im assuming it wont be fixed under warranty
No Nandroid backup ???
jje
No backup, I backup files and wipe generally, but the phone can't sync with the PC so I can't reinstall a different stock firmware.
I'd pay good money if someone could fix this or had an idea how to fix it?
First step would be back up data and factory reset .

See my thread here.
If the modem/pda fix doesn't work, try another USB cable - you might be pleasantly surprised.
I know I was...
Excellent advice. And also along this line of thinking, another PC/OS might be worth a shot as well if nothing else works.

You did
Tried the dialpad PDA/Modem hack? From my googling last week, it doesn't seem to have worked for the majority.
Ive now tried a new cable, Ive tried restarting the phone when its plugged into the pc but when its powered off and charging it will not turn on no matter what I do.
I have tried uninstalling kies and restarting then letting windows install a driver but it installs the old driver I believe.
This all started with 2.3.6 and as far as I can tell, I must have installed the wrong version for my region or something and its affected the way it shows up.
i had exactly the same problem from an hour to another i was really pissed off,
i had a nandroid backup but that doesnt helped much.
the thing is i reinstalled my computer clean install without any software only kies, cleaned the usb port of the cellphone and by doing that i got my cellphone recognized at odin sometimes, when i got recognized i pray it doesnt disconnect and flash full XXKI3 with pit file and problem solved, don't know why this happened but i was going crazy haha
a tip that helped me with odin. get to device manager with the phone plugged in and disable unknown device ( the one that cellphone is) then if you reconnect your cellphone twice for me it's work on odin!
the main problem for me was the unknown device you had and that it reconnect constanly, also you have to know the solution for me was xxkp8 with pit that solved my problem then went to xxki3 and is was solve already but i think xxki3 willl be the same for you, i whink the clean install with pit is the solution, maybe someone can correct me, this worked for me (i thought it was the usb port and my guarantee is under USA and i'm from argentina so i was getting crazy, i tried all and this helped (also with this problem couldnt go back to stock firmware :S)
good luck i hope this help you
PS: i tried all sollutions they said to you here and nor one helped! and searched the hole forum and nothing helped me!
PS2: i thing it can be related to something broked on the cellphone software, cause my region last firmware was 2.3.4 i was using simple and clean rom 2.3.6 not for my region without a problem and suddenly this happened now i'm again on S&C cause it fits for my usage and no problem at all!, something messed up the cellphone maybe a buggy flash of siyah kernel by the time it happened to me i was testing siyah 2.6.3 i think and it was really buggy for some people
Hey fdbailes,
That pretty much sounds like what is going on with me, I've tried what you suggested but sometimes when I plug it in, it doesn't even detect a device, the PC makes the noise but nothing happens.
It's really very disapointing, I am a carer for a disabled person so I have no money to buy a new phone and I really really want ICS on my galaxy.
Thanks for the help, Ill keep trying, what version of Odin were you using?
Did you use the stock Samsung Cable?
I cant think of anything else except
Does anyone know if its possible to install a new kernel from the SD somehow?

Mobile Odin, if you're rooted.
I am not, I'm on 2.3.6, please tell me theres a quick and dirty mobile root? lol
I'd settle for hugely complicated and filthy....
Edit: Would is it possible/would it be possible, to update firmware or root over wifi or bluetooth?
I was thinking that you could install the cwm manager apk, but I'm not sure if you have to be rooted to install it... Brain not working well today, anyone else can confirm/deny?
You can but try anyway. Download Superuser and Nitrality from the market, use Nitrality to install the apk, see what happens.
View attachment CWMManager.apk
Blast, CWM wont run unless I have root access.
Also, Nitrality keeps crashing at launch
Did you ever find a solution for this?? I just got a new tmobile sg2 but my laptop is doing the same thing?? I really wanna root it already

[Q] Help Please! I am NOT a noob- tried many ways but stuck trying with a work around

Happy Holidays Everyone!!!
Phone:
Tmobile T959 aka Samsung Vibrant
It is on stock Froyo 2.2
It has the 3E recovery.
I tried on 2 computers but I can NOT connect via USB it gives me USB malfunction error. The phone does charge. I can put it into download mode vie the 3 finger trick. When you connect it does give you the option to click the green Android icon Connect to USB. So it is talking to the computer, the usb is not totally dead.
Problem:
I need to root this phone. I can not use 1 click or anything else because I think there is a problem with the USB port. I can get files onto the phone via wifi or using the external sd card.
I tried using the update.zip file BUT because I am on the 3E recovery it will say signature failed. I can not run the install.bat to get it back to 2E recovery. I can not use ODIN because the Windows will not detect the phone properly.
What workaround can I use to root this phone? How would I use terminal on the phone?
HOW WOULD YOU ROOT THE PHONE IF YOUR USB PORT WAS "broken"?
THANKS for helping!
As far as I'm aware, you can't root your phone without the USB port working as most (if not all) root methods send their commands and files through ADB. Your pretty much stuck, unless your phone is under warranty. In that case, just go to your carrier and see if they'll give you a replacement device.

It's out of warranty
I think there may be a way to do it via terminal emulator on the phone.
If this is possible, can someone please post how to do it.
anyone with a work around?
damn!
Am I stuck or does anyone have a way for me to root this phone without the using the USB connection (USB does charge, It will know when you connect to the pc for USB storage BUT windows will say not recognized. I tried it on 4 other pc's same results. I think something is wrong with the OS of the phone. I think the previous owner tried to update with Kies and it messed up the phone. The phone does boot and works.

I did all of that.
I think something is wrong with the phone's OS that is effecting the usb port.
How do I root this phone WITHOUT the USB port?
There has to be a way!
Can you determinate VID&PID of phone?
I can get into the device with airdroid and see the system files.
Which files do I need (or which apps) and where do I copy them manually to get it rooted?

Is there not a device forum where you might could get some better information? My thinking is, a lot of the people (or most of the people) who may know some workarounds can probably help, but they don't check this section very often or at all.
Even if there's not a section for that model, I'm thinking there's probably one quite similar. Also a lot of times, a big portion of the userbase of one phone, will migrate to the same model when they upgrade.
Just throwing out some ideas in case that's helpful. My only advice on the problem itself is that I would look further into the driver issue. I've helped several people with very similar issues that we finally were able to correct.
Have you tried to ADB the device just to pull the serial? With USB debugging enabled. Have you installed the SDK and tried the naked drivers? There's some things to pursue possibly so you can have more information for the person who helps you get things straightened out.

MTP Driver Install Issue

Hi All...
Not sure if this is ROM related, ie a bug, but I seem to have trouble connecting as MTP. I know I connected before changing to the Jelly Thunder ROM as MTP without issue. I connect my phone to the usb port and its set already to PTP and then I try to switch it to MTP and it automatically unselects itself and selects PTP again.
Things Ive tried to resolve:
I read something about having USB debugging on may affect it so I tried turning that off, but no luck.
I tried reinstalling the Samsung Drivers from their site and no change.
I also tried the Kies drivers resinstall and that didn't help.
I have tried to mess with the registry the the "upperfilters" solution found on many SG3 pages with the same problem and that didn't help (plus I don't have a "upperfilters" key, but one solution had me adding it and then removing it in some sequence of having the phone connected to computer and removed).
I tried adding my device ID to the wpdmtp.inf file as one SG3 thread suggests and that didn't help.
I am fresh out of ideas to try. One suggestion from another member in the Jelly Thunder thread, where I first posted this question, suggested trying the hidden menus mod, which I have yet to try. I feel like I shouldn't have to go to that measure to get this to work. There was also some talk on another SG3 thread about doing a factory wipe on the phone to fix it. WHAT?... that seems like a hell of an answer.... loose everything and have to start over with settings and the like.
Any help greatly appreciated...
Thanks in advance...

Odin.

Hey guys. I'm having some big problems here.
The thing is,Odin was reading my phone perfectly when in download mode before. Now,it just doesn't wants to do that. I tried everything possible. Starting from different versions of Odin and ending on reinstalling samsung drivers/kies. Can anyone help me with that? Seriously,this is the first time I can't solve a problem.
Btw,I can't try any other cable for now,but I remember having same problems with other three cables I had and problem was getting solved by reinstalling drivers or using connecting to another port. But now nothing works.
Any help?
It's either a lead or windows issue, find a guide on how to completely remove USB drivers and devices.

LG G5 Bootloop

Hi there,
I recently bought a cheap lg G5 from eBay which said it was stuck on a bootloop. The seller said they weren't very tech savvy and I decided to give it a try, seemed fun. I have never done this before, so when searching on Google I stumbled upon threads saying it should be rather easy to fix by using LG Bridge and let it recover/repair the installation. However, after installing LG Bridge and LG Drivers from their website , every time I boot the phone in Download mode and it progresses into a firmware updating screen, my Windows 10 64bit fails to connect the device properly and prompting me with the following message:
USB device not recognized.
The last USB device you connected to this computer malfunctioned, and windows does not recognize it.
And in device manager it shows "Unknown USB Device (Device Descriptor Request Failed).
Is there anything I could try? Is it fixable like I thought?
Bump, anyone? Im stumped but would love tot learn about this

I have never had the experience to get a bootloop but my guess is that you have some driver problems, thats why its not well recognised by your computer.
Try to check if there is a youtube tutorial with some links to the drivers related to the G5.
Sorry if this isnt very helpful, but its the best I can add to this topic.

Or try with another pc running windows 7, maybe your OS and compatibility is the problem!
Definitely a driver issue! I had a similar problem with moto x4! It was not being recognised by my pc! Uninstalling the previous usb driver fixed it for me! Try to remove any remnants of drivers you might have installed previously.
Thank you for the replies. I also thought it would be a driver issue, however I have already tried uninstalling and reinstalling the LG drivers for the LG G5 multiple times and I did not get it to work. Unfortunately, I do not have a Windows 7 computer. Would it be possible to install windows 7 solely for this, without a license key?

If you can find a copy of it some where. You can use it for like 30 days or so before activation.
I do not know any coding, and have never even rooted a device, but i had this problem with stock rom 8.0, tried looking into flashing new stock rom installed all the drivers, still couldnt connect to pc. After 4 days with no phone i thought id throw my other battery in it, it booted up perfectly like it was out of the box, probably because i tried the restore in safe mode... Hope this helps... P.s. id like to learn
