Hello, I recently decided to root my phone and place Cyanogenmod on it. When I did that I realized my radio was no longer working. In an attempt to just get back to a working phone for the time being I flashed a rom that I believe was just for the Nexus S and not Nexus S 4G. Due to my stupidity I am unable to communicate from the device to my computer using USB. When I attach the device to the computer nothing happens. The device does not even appear in the device manager. I have tried on multiple computers as well. On top of that the rom seems to have put me back into the stock recovery. If anyone could help me figure out just how to get USB working again I would be very appreciative.
I should note that I can still transfer files to the phone using the sd card or via ftp.
Thank you for your time and help.
Change the USB cable?
Yes, forgot to mention that. I have tried 2 cables both of which work on other devices.
What if you hold in the middle of the volume buttons (i.e. both up and down at the same time) and keep holding, then plug in to your usb port? It should come up as download mode. If it will do that you might try using Odin.
Or try a different machine perhaps?
are the drivers the same for the S as the 4g?
do you have clockwork on the phone or have you tried to run recover by holding volume up and power?
just throwing things out.
Hello, I appreciate any and all suggestions and help.
I have Odin downloaded and installed, but the computer can not find the device so Odin can not do what it needs to do. This is even the case in download mode.
In terms of recovery I am on the stock recovery. I was on clockwork but made a small mistake and now am back to stock.
I know if I can just get the computer to see the phone exists I can fix it.
If you can find the full OTA package for NS4G, you can try putting it on the SD card and flash it via stock recovery.
Also another thing worth trying is connecting the phone to an Ubuntu machine and see if it's detected or not.
I have tried looking for the original full OS. I will continue looking, but the different OS thing is a good idea I did not think of. I will attempt that now. Thank you.
I installed Ubuntu and the Android SDK and Ubuntu was unable to see the phone as well. I am going to keep searching for the original firmware to see if that will fix it. Thank you for your help so far, it is greatly appreciated.
I have found the only rom my phone will accept now is
Android 2.3.4/GRJ22/KRKC1 Radio/KA3 Bootloader
Which is for the M200 variant. This apparently the Korean version.
ok i need help please , i had gbread on it and installed superoneclick to get root then tried to flash cwm with vipermod. message said out of storage space or something (dont have ext mem only internal)and now phone will not turn on.
have followed this guide http://forum.xda-developers.com/showthread.php?t=1244490 and phone was recognised by omapp but couldnt change the port in device manager and couldnt find a bin to download so i tried to flash a kdz v21a
clicked start on lgflasher but nothing happened so after about 5 mins i cancelled it thinking without the port change it was a waste of time.
now i cant even get omapp to flash up when i connect phone . device manager refreshes but i cant see anything change .
hope thats enough info for some kind person to help.
many thanks in advance
marty

Where did you get vipermod from? The Transformer Prime forums? That's meant for the TFP and would not have worked with the O3D since it flashes to mmcblk0p4 rather than mmcblk0p. You should have used the flasher here.
Download this, this and this. Extract smartflash.zip, install both driver packages. Then, run Windows Enabler, in the notifications bar, click it and make sure it is set to 'on'.
Now remove your phone's battery and sim card, press volume up and connect your phone to the computer. Hold volume up until it is detected by the computer. It should take no longer than 20 seconds.
Now run B_SmartFlashTool_Extern.exe, go to rom copy d/l, select LGP920_CP.fls for CP bin and LGP920_AP.bin for AP bin. Make sure under communications setup that your phone is connected (verify the com port in device manager) and then click start. If all goes well, you'll have a stock v21D phone again
Thanks for the help guys but i'm not getting a com port when i connect the phone so i don't think i can use any of those methods . or can i
i want to go back to the beginning and see if omapp will detect phone and install drivers but i can uninstall the installer but dont think that will remove the drivers , does anyone know how to do that.(cos i think i messed that bit up )
thanks again
marty
vipermod , i think i followed a link somewhere in the o3d forum where someone said u could use it to flash cwm
so , i uninstalled all lg drivers uninstalled omap installer searched registry for for any mention of omap and deleted (some wouldnt delete ) .
restarted computer (xp by the way )
then installed omap installer and lg drivers and connected phone holding vol up
and................. NOTHING whereas yesterday i had a little icon in the task bar and the opportunity to install omap drivers.
conclusion , phone is dead , i had an oppurtunity to fix it yesterday and i blew it
hope someone tells me i'm wrong but its not looking good
marty
take off battery and just put your usb cable and tell us if it shows omap in your device manager
dont press keys
if i connect phone without battery device manager just refreshes a couple of times but nothing changes with regards to ports doesn't matter if i have vol+ button in power button in or nothing
thanks anyway
marty
am i getting somewhere
update : ok so i'm on a clean install of xp and i connected the phone with vol+ and it wants to install omap4430 drivers. is that good news?
i installed omapinstaller , then the 2 lg drivers ca and ma , then reconnected the phone and went thro omap driver install but still don't have any ports in device manager
is there no way i can force it to flash without it having to think it is connected cause if its recognising it as omap4430 there must be something there
don't want to give up on it too easy , if only i put this much effort into it whilst it was working lol
marty
evening all . new update
tonight i've installed the lg support tool and drivers and found that if i leave my phone connected i occasionally get "TI sample boards" popping up in device manager for a couple of seconds without having to press buttons , unfortunately it doesn't stay on for any longer with buttons pressed.
i was wondering how to force install the "LG CDMA composite usb device " drivers cos its never asking for them as it should according to the tutorial
hope someone can help cos i've seen a few threads with same problem as me
marty
I've looked at the similar threads , to be honest even if one of the suggestions might work , none of the people seem to have the same problem from my understanding.
So apologize ahead of time as i imagine someone has bricked in a similar fashion in some thread buried somewhere.
But have an unlocked P925g lg optimus 3d, got a few days ago.
Last night i rooted just fine , root checker says it was rooted properly.
Then i installed rom manager as i was following manbearpigs post.
When i got to flash clockwork mod , i clicked the button and it looked like it was doing some flashing , but the phone turned off to reboot??
and now when i power on the lg logo appears and then the screen goes funny.
If i try to hold the power down and 3d button , i get a green screen . However i'm very unsure of what to do next.
However when i plug into usb the phone goes black , refuses to turn back on until i take the battery out.
I'd pay someone here if i could , but i'll take any help i can get.
Appreciate any help.
I don't KNOW, but just an idea:
May be your phone is stuck in download mode?
With this latest ICS (original, not ported) my phone shows black screen when in download mode (no message SW UPDATE and something in Korean).
Did you try to plug your phone to PC? Does your comp see it?
From what I read flashing wrong CWM might cause problems...
Also try to read Ressurection thread by xbsa, it helped me couple times
Don't give up!

My computer does see the phone if i take the battery out , and push the volume down while it connects. However when it connects , it cannot find drivers that it find originally.
I'd be happy just to have the phone back to froyo right now , however i am not giving up , just asking for advice. Will reply once i look at the resurrection post you suggested.

just try the LG flash tool to flash without reinstalling drivers, if it doesn't flash you have to uninstall all LG drivers, reboot your computer, install again LG drivers and flash Bin files using Flash tool, you don't have to flash Bin and fls files at the same time, first Bin file, if there is no network close LG flash, open it again and flash Fls at second time to get the right baseband (sometimes it not necessery to flash this fls files)
or just follow this guide

To get to download mode you need to keep battery in, remove sim and SD card. Hold vol+ and plug USB cable. You should see message SW UPDATE and some Korean. My phone now doesn't show it, just blank screen. But LG Flash sees it and u can flash bin fls.

Remove drivers and use the LGMobile Support Tool to install the drivers, if your phone is connected it should detect it and finish the install process. I believe the P925G is a Rogers device? You might have to select Rogers as your carrier to find the drivers.

ok so i've deleted all lg related material from my computer, when i connected the phone to the computer with battery in , nothing happens.
Without battery , it detects automatically , then it continues a loop of picking it up and dropping off .
So i moved to my laptop , attempted to follow the guide kupuku posted, however after getting the went logo on the phone , it never gets past that stage no matter what i do.
I've also tried LG support tool , it doesn't detect my phone on either my computer or laptop , even after installing/reinstalling the proper drivers.
LG does have a live chat which isn't open and the phone number can not be reached from my area.. i imagine its a 1800 number for asia or something as i do live in Canada.
My only other choice is to take the phone down to a guy that can get it out of boot loop for close to what i paided for the phone a few days ago.
Least to say , that option is something i want to do , nor can i afford to do.
once again i apprecaite the help that has been given , and for any that will be given.
edit:
Ok so i got lg mobile support to work by doing recovery and entering my imei number. Its currently at 4% but its been close to an hour and a half. Might restart and see if that works , but my phone is doing the logo boot repeat pattern still , even during this update. so not sure what exactly is happening.
hello,
I hope someone can help me with my AT&T LG Optimus Pro G phone, which I have royally screwed up.
I was experimenting with the cyogen mod and after installation I installed the freegee app and once the cwm recovery was installed, I decided to go into the recovery by holding down up volume and power button.
Once I was in recovery for CWM i couldn't exit out, and the phone constantly booted into recovery after every reboot, even if i took out the battery, and powered it on.
I tried reflashing the cynogen mod through the sd card, and even though I would get success message the phone would still reboot into the cwm recovery.
I started doing research on the internet and i found file exitrecovery.zip that could be used to possibly get the phone out of the cwm recovery.
After installing exitrecovery.zip, I rebooted the phone, and now I have complete black screen. There are no light, no hints the phone is even turning on, and I can't get into recovery( or at least I can't tell). The only thing now is that when i connect the phone to the computer the window tries to install drivers for the device, and eventually prompts to insert a CD for LG drivers. I already have LGUnitedMobileDriver v.3.10.1 connection drivers installed from their website.
Please help, I am really stuck here..... and have no clue what to do. I am fairly new with rooting and modding, and I am extremely miserable.
The phone is still under warranty from LG. Anyone if all else fails, and since the phone has no screen or lights, whether they would replace it?
Attaching the exitrecovery.zip that I used.
sobbing....

hi, thanks for your reply. Again I very much new to the rooting and android OS tinkering, and nowhere close to an experienced user.
I tried to use google with your information in regards to how to use flow ROM with expansion.exe, but did not get any leads.
I would appreciate if you could elaborate more on this process.
When my phone is connect to the computer via usb is is constantly trying to install drivers. I had already installed LG usb connection drivers in the past and it was successful. It almost seems it tries to install driver yet fails after receiving no input from the phone, and then request LG CD with drivers.

Try to find driver on the web-site of producer. Set them. Overload a vehicle in Bootloader. In the controller of devices on компе must be determined your device. Then on a computer start sewing - .EXE.
Did you get this problem resolved? I have the exact problem with the exact phone!!!
thank you very much

You need to download a MetroPCS KDZ and use rhe LG Flash Tool to flash the KDZ and bring your phone back to life.

To get into download mode you need make sure phone is 100% powered off then hold the volume up button and then plug in the usb cable. Dont release the power up button until the phone is fully in download mode not just the first screen. Also search for your phones adb drivers and install them to your pc not just the usb drivers. Make sure to uninstall any existing drivers first.

Did you try another pc with the adb drivers installed to see if you get the same error? If it connects on a different pc try this on the problem pc.
Open task manager
Click on the Hardware tab
Click the Device Manager button.
Expand Universal Serial Bus controllers section.
Right-click every device under the Universal Serial Bus controllers node, and then click Uninstall to remove them one at a time.
Restart the computer, and allow the computer to reinstall the USB controllers.
Plug in the your phone in download mode and test to to see if the issue is resolved.
You can also download Ccleaner and fix any registry errors for free. I've used it for years and it works really well.
Still no joy. Try a system restore on your pc sounds like the device management could be screwed up.
All kinds of funky sh*t can happens when a pc crashes. You said you have windows 10 as a last resort you can do a system refresh which reinstalls the os but keeps your files.

Everything you need can be found here in the LG G Stylo forums and if it's not here a google search will help.
You need...
MetroPCS 5.1.1 KDZ
LG drivers
LG Flash Tool
Download the KDZ. Install the LG drivers while you wait for the 1.2GB KDZ to be downloaded. Download the LG Flash Tool and when the KDZ has completed downloading run it as an administrator. Settings in Flash Tool should be fine. Point to the KDZ and begin the flash. Normal or CSE. Normal does not wipe data, CSE wipes all user data. You'll be prompted with something about your internet connection. Do not close this, the tool should be flashing the KDZ. Wait for the phone to be rebooted after flashing. Profit.

I had the same problem once the device connected as download mode.
The kdz tool doesn't detected and crashed all the times. But miracle happens I kept playing(open&close)the kdz tool app. Somehow it detected and flash the kdz.
Android Studio was a bust still unable to find my device even with the code to direct information to the only USB device connected

I was under the impression that the phone was entering dl mode but just not getting recognized by the pc. Either or you should bring it to a corporate store and tell them it boot looped while updating and play dumb. They should replace it since its under warranty. Or call lg and do it that way although its about a ten day wait.

My phone does enter download mode just can't do anything from there. ADB can't find device. I even found the port I'm in and tried to force into recovery but still no device connected.
