1. Did you have ADB and fastboot drivers installed?
2. Did you enable USB Debugging?
3. Use USB cable that came with your phone.

Flash stock ROM here: http://www.mylgphones.com/sprint-lg-optimus-g-ls970-software-update-ls970zvc.html
Or I'm wrong?

I don't know why my device won't be recognized I heard it might be a kernal from another thread with a similar situation.

Man you really don't have a clue do you!!
Why in hell would you need OTG to flash a rom? Do you even know what OTG is?
Stop ignoring people that give you the solution too. It's really bad manners.
So download the stock rom and flash it.
You should spend a day reading up first before you damage the phone permanently.

Sorry if not being clear I have been listening my phone has a hardware issue and I'm not to much of a noob have tried each comment. I'm not to nooby but I have downloaded the drivers my device is not being recognized correctly I have a hazardous icon in device manager on my android phone lg ls970. My phone does not support otg I'm trying to install .zips through a flash drive and otg cable. I'm sorry if waisting peoples time with my apparently nooby question. Please c correct me if I'm wrong thanks for the support.

Let me be clearer I'm sorry for not spelling it out well enough. I have installed drivers many times I have installed the driver however my phone is not being recognized correctly I have uninstalled and tried again. Otg which I looked it up pretty handy in these situations, doesn't work for this phone (due to outputting)I had a cm10.2 kernal which may have had something do do with this. I have come to believe that its a hardware problem with the female port I will try again on another computer tomorrow and see.
What I want to know is why it still recognizes something and if its fixable?
Thx

I have fixed thanks luqman98 it was a problem with windows not allowing me to install drivers due to 8.1 update

USB drivers & problems

Hardware ID not found and all drivers dont install :/

Sounds like OS problem. Please provide more information. Which ROM, which OS on PC, did it work before, etc....?
You might try a LiveCD (Ubuntu, Knoppix, ...) and connect your phone as USB mass storage device.
Im on stock ics i got it today..
Stock ICS does not support USB mass storage anymore like Gingerbread did, even if USB debugging is enabled in developer options.
To regain this feature you need a custom kernel (Siyah or Dorimanx). I also ran into that issue last week...:silly:
If MTP or PTP don't work either you might try to uninstall KIES, reboot PC, and the reinstall it again. Also connect your phone to a different USB port.

Even if you have the correct drivers installed, some bad drivers might be picking the device up, overriding the good drivers. If you open up device manager, what shows up when you plug in the phone?

Snappea is an app for both windows and your android via which you can connect to your pc
1. First download and install Snappea (Google it "SnapPea" since i cannot post outside links)
2. When installed, it will ask some basic info and after connecting your phone, it will automatically download its android version
3. I guess thats all.... Youll understand its use via the tutorial (pretty much easy)
4. ENJOY!....enjoy transferring your files via pc and android........

What makes a sound when you connect it to the PC? Does the PC itself make a sound? And you did as I suggested and had Device Manager open when you plugged it in - did it refresh at all?

Strange! Do other devices work when plugged in?
the device makes a sound means it connected to USB only. it can be computer or charger.
did you try uninstalling usb drivers in device manager.
right click and update driver
then select have a disk..
show path ..Program Files\SAMSUNG\USB Drivers..
i can't remember the rest of the part.
then it will recognize
hope this help..

Oh then Idk i've never looked into it.
I'm having the same problem with my i777 model.
I uninstalled and re-installed the drivers, I updated the drivers, I tried debugging mode and I've tried "Mass Storage" mode.
Mass Storage mode was the only one that seemed to work for me, when I tried debug mode it would constantly connect and disconnect.
When I try without being in any of those modes, my phone will connect. My computer will recognize and then randomly my phone or computer wont be able to see each other anymore. Like my phone will disconnect from MTP-initialization (but still charge like it's plugged in)...I'm really interested in rooting my phone, but I don't want to since I can't connect my phone correctly. I don't want a $200+ phone becoming a brick and I can't replace it very cheap (anytime soon at least).
Here's phone info if it helps any..?
Model Number: SAMSUNG-SGH-i777
Android Version: 2.3.6
Kernel Version: 2.6.35.7
Build Number: GINGERBREAD.UCKK6

Hmmm...I just tried something. My phone says it's not in MTP, but my PC can read it and open it up.
All I did was turn off my phone, then I plugged it in, then turned it back on and it's doing good so far...might give it a shot, I dunno how well it's really working or nothing though.
|-----EDIT------|
Now it's in MTP Application and synchronizing, I'm just trying to back up my phone with Keis so if I do decide to Root, I can back everything back up.

Phone not detected by windows 7 help!

Hi guys,
I'm new to this forum. I've got a Samsung i777 on android 2.3.6 kernel 2.6.35.7 build number gingerbread.uckk6
I've recently bought this phone off ebay
My phone does not get detected by windows 7 or Macbook. I've tried changing the USB flex cable with I9100 v2.3 but still no luck.
When I connect USB port it beeps and shows mtp-initialization/mtp-connected on the phone but it is not shown on windows. It says USB cannot recognise the device. I've got a s3 and ideos x3 both of them are detected.
I've installed kies 3 on my laptop.
I had to swtich off the wifi on the phone because it consumes a lot of battery, I think it is because of the android version I'm using!
I want to root the phone and unlock it!!
Any help is appreciated!

I'm guessing the problem is the Samsung drivers you have installed for the s3. Try uninstalling those and installing the correct drivers for s2.

You most likely need a new cable. Happened to me once! Could be the drivers but I HIGHLY recommend just trying a new USB cable.
Thank you guys for all your help really appreciate it!
I have tried all the steps mentioned above tried to uninstall all the previous drivers I had and installed the new driver as mentioned in the above link but no luck
I tried it on a friends computer with a different cable still it shows the USB device is not recognised!!

Did you install another ROM? It might help to Wipe system, Data, ETC! it appears to be a software problem. Or at least my guess is the ROM your using.
The Galaxy phones all use the same USB drivers whether it's an S2, S3, S4, etc., so if the installed drivers were working for your S3, it's unlikely to be a driver issue.
Can you boot it into download mode? If you happen to have a USB jig, that's the easiest. Otherwise, power off the phone, unplug the USB cable, hold Vol +/Vol-, then plug in the USB cable. It should go into ODIN download mode. See if Windows detects the phone that way. If so, it very well could be something weird with the OS installed (although it appears to be stock).
If you can get into download mode, you can flash a stock kernel to make sure you are starting fresh. A good file repository is found here. I recommend the stock UCKH7 image I777_UCKH7_OCD_No_BL.7z (you'll also get root).
And yes, the UCKK6 release had a serious bug related to the wifi that could drain your battery. Best to go with UCKH7.
You could also download an app that allows you to enter download mode.

I was able to boot to download mode by holding the vol +/- key and then plugging in the USB cable but there is no movement from the computer it doesn't make a sound nor does it detect. I tried restarting the phone then I get a notification on windows that USB device not recognised!
Yes I guess this rom is useless, if the wifi is switched on then battery would not even last 6 hrs!

Are you saying to get a balloon notification in the tray that says the USB device is not recognized? A possible reason for that is a faulty USB cable or USB port (funny enough, I actually got that message last night when I was playing around with my Captivate, and switching USB ports made it work). I know you said you've tried other computers an another USB cable, but that's about my only idea. Maybe there's some debris inside the connector that's messing up the connection.
When you say you changed the "USB flex cable", are you talking about the internal connector and board inside the phone? If so, perhaps the I777 connector board is actually a little different than the I9100 board and causing a compatibility issue.
The bug in UCKK6 related to wifi didn't affect everybody, but it definitely affected a lot of people (based upon reports here).

If you have an SD card, you can download another ROM on that SD card from your computer and then you can install custom recovery (CWM) and then install the ROM from SD card.

First ill run you through the problem I had. Just for reference did you use Mr. Cooks script before flashing Cyanogenmod 11? One of his scripts for cleaning before flashing, actually deletes a certain file, not to keen on which one. What it results in though is not being able to flash OF ROMS and some certain custom ROMS! So id recommend alliance's ROM! As for the "Getting the ROM on your device, you could put the ROM on your SD though recovery "Mount and storage/Mount mass storage/" or just use a micro sd card adapter and move it on there that way.
Thanks for your reply. Would you mind sending me the link on how to do that step by step as mentioned I'm new to Samsung phones and also this forum.

What state is your phone currently in? Is it still not detected by the computer? You are still on 2.3.6, correct?
If it's still not being detected by your computer, I'm not sure if you can flash anything needed using the stock recovery. I know that when I flashed stock JB, I was able to boot into stock recovery and directly apply the standard CWM update file here. It will give boot into a temporary CWM that should allow you to flash other ZIP files (like a ROM), although I had trouble doing that (so I ended up flashing the AJK_v4.9_NoSwap.zip kernel using the MobileOdin android app, which gave a permanent CWM recovery).
I'm not sure if this same process works with the 2.3.6 recovery. However, in order to get the stock recovery to see the internal SD card, I had to run adb shell commands to mount the partition (meaning I had to have a working connection from the computer).
Solved!!!
HI Guys,
Many many thanks for all your responses!
I have changed the USB flex cable again to an older version v2.2 and my phone is currently being detected by kies! So relieved thanks a lot for all your help..now the rooting begins!!:laugh:

P769 hard brick?

a day after i rooted and flashed a rom on my l9, it just died, idk how. can't get into any kind of "mode". the strange thing is when i connect is via usb it tries to connect but a dialog box comes up in the bottom right saying "USB device not recognized" it makes the connect/disconnect sound over and over until i unplug it. Device manager doesn't show anything, it just keeps refreshing because the device is attempting to connect. I've tied different cables and different ports also, and no luck.
any help will be greatly appreciated, thanks

well, you could try another USB port in PC or another Cable, it's may not be your USB, could be another thing of what i mentioned above, or it could be the drivers are not installed correctly.
