[tripdoc79]

Cant get drivers to load. Keep getting,"Specified location does not contain info for your hardware". Had it rooted to 2.2.1(stock 2.2.2) and regained my cell signal. When I went to recover I must have hit a wrong key or recovery file didnt actually load fully. Wifey is not gonna be happy if I have a new 130 dollar paperweight. Thanks in advance for any help.

Got it to work and accidentally rebooted back into fast boot. Now when trying all i get is bad block error cannot erase on the phone, when going back through the steps. cmd says ok and finished.
any ideas?
Tried erasing partition and get unknown partition error in cmd. I had to use the generic google usb driver and it comes up as adb interface in dev. man. since the provided drivers didnt want to load.
Should have just left it alone I am fearing.

 

[shromy]

this has to be fixable. I can command fastboot to boot a boot.img provided with the team chicken eater rom and I get my charging screen as if the phone was off and charging. keep trying things to no avail,newb at this so learning proper command lines.

I have received like hundreds of pms from a lot of people telling me to get their phone out of Fastboot Mode. Well from now on people wont have to wait for me to help them, they would be able to do it themselves.

1) Setup

Download my fastboot files here.
Unzip the files to your C:\ drive.

On your C:\ drive you will see a folder named Fastboot after you unzip the files. With some files and folders on it.

Now double click on LGUnitedMobileDriver_S497CA20_WHQL_ML_Ver_1.0 to make sure that drivers are installed. The file doesn`t show any interface, so just wait 5 minutes then continue with the guide. Picture below show contents of folder and files.

Now that drivers are installed; connect your phone to the pc. Most of the time the computer will install the drivers for Fastboot mode but if it doesn`t I`ll tell you how to do it. If you saw that the computer installed the drivers then skip to step 2.

Right click on my Computer. Click Manage. Then on the left bar click on Device Manager.

Now just follow all the images below to install Fastboot drivers.

2) Usage

Now that you have the Fastboot Drivers Installed. Lets continue with all the commands.

Open Cmd and type or copy and paste these commands ONE BY ONE:

cd C:\Fastboot\android-sdk-windows\tools
fastboot erase boot
fastboot erase recovery
fastboot erase system

Now we need to flash recovery via Fastboot. Type or copy and paste this command on Cmd:

fastboot flash recovery C:\Fastboot\Recovery\recovery-RA-optm-2.2.1-GNM.img

Then type this on Cmd to reboot to recovery:

fastboot reboot

Now your phone will reboot to recovery. All you have to do now is to install a rom and your phone will be back to normal.

Hope this helps.

Ok. So I got into fast boot mode some how today. I was doing something with trying to re-flash recovery (going from CWM to GNM's recovery) and it went into fast boot mode. I have XP and so my options are slightly different than yours, but I was trying to follow along. When I got to the point that I select the lgandadb.inf, and then select ok I get an error that says "The specified location does not contain information about your hardware." I tried some of the other drivers in there with the same results. Any thoughts on this?

I haven`t done it in XP, but you could try installing the drivers again and see if that works. If it doesn't; let me know and I`ll see how I may be able to help you.

 

[tripdoc79]

yeah.. if you ahve the drivers installed.. it should just pop up "installing new drivers" when you plug the phone in while in fastboot mode.. or check your decive maanger and see if its showing up as a fastboot device

 

[alfick3]

Update: I went over to my wife's computer (she's got Win7) and was able to get it all working! Hoo ray! For some reason I couldn't get it to work on my XP Pro.

 

[tripdoc79]

Yeah its much easier than the lgnpst method lol especially if you have a backup

 

[DaniellieeE]

Yeah its much easier than the lgnpst method lol especially if you have a backup

Yep agree - have Win7 - n that does seems to work much easier- much less steps, if I'm not mistaken

 

[tripdoc79]

yeah.. win7 with drivers installed.. just need fastboot on ur pc.. plug phone in, shows up as fastboot device, move recovery into folder with fastboot, open command prompt, go to fastboot folder, type fastboot flash recovery.img and done lol, reboot into recovery, restore. golden

[tripdoc79]

[BMC500B]

Make sure that you are typing this into cmd, also that you extracted the downloaded .zip file to your C:\ drive

This is what you should type into cmd after unzipping the file:

cd C:\Fastboot\android-sdk-windows\tools
fastboot erase boot
fastboot erase recovery
fastboot erase system

Then type this to flash recovery and reboot to recovery:

fastboot flash recovery C:\Fastboot\Recovery\recovery-RA-optm-2.2.1-GNM.img
fastboot reboot

PS Type one command at a time in cmd.

Hope this helps

Make sure that you are READING the guide. All of it. I just said that nothing comes up after you open the drivers file. So just wait 5 mins then continue.

Ps Not trying to be mean or anything, but you need to follow instructions to make things right.

Hope you get the phone out of fastboot. LOL

Hi, when I try to get the thing installed, I get this:

Sorry for posting a website, but I can't post pictures yet. Anything you can offer as help? Please?

 

[Cyndaquil]

Okay, I finally got it to work, but after doing all the fastboot stuff, it still goes back to the fastboot screen...

 

[rustbucket1515]

ok what if it says, driver is not compatible make sure is designed for windows 32 bit system?

 

[yahhboy]

Thanks alot my phone got stuck in fast boot mode while trying to used flash image GUI with gnm customer recovery. I thought I was going to have to do the lgnst thing but thanks alot save me alot of time and trouble

+1 I got into fastboot trying to flash cwm through flash image GUI, just wiped the recovery partition and pushed the gnm recovery on

 

[Mephisteles]

Joneidy, your instructions require that the Android Device is recognized in the Device Manager. What can one do if they are stuck on Fastboot mode after failing to properly flash a custom recovery and their PC doesn't recognize their device?

My device isn't recognized and it's held me back from completing any of your detailed guides.

What can i do?!

 

[alfick3]

Once again, this guide saved my bacon. I was trying to use the flashimage gui app to flash playfulgod's newest CWM recovery (CWM 5.0.2.6) to replace the version 4 something that I had, and it went into fast boot mode. Oh well. This time around though, I placed his recovery image into the recovery folder and flashed it instead of the GNM recovery that is supplied with the files provided in the OP. It worked like a charm. I do have the CWM recovery and am in the process of restoring my most recent back up made with CWM from a couple of days ago.

 

[KrazeeCracker]

FML this guide had me stuck on waiting for device. So i said **** it and went ahead and just reflashed sense from the revoery and all is well

WOA: stay away from the V6 supercharger! shit ****ed me up bad!

 

[BlitzAuto]

You need to install the correct drivers, in your case the drivers for the Optimus T. Also flash your recovery via fastboot. So just follow the guide using the drivers and the custom recovery for the Optimus T.

Hope this helps

I'm having the same problem, being stuck at "waiting for device".
I've installed the LG drivers that joneidy included with the fastboot download but it's still getting stuck.
I also tried other drivers downloaded from LG directly and get the same "waiting for device" with each and every one of them.

I'm running Windows7 Ultimate 64bit if that makes any difference?

When I try joneidy's manual driver instal method, it comes up with that drivers not found error as well.

If anyone can help shed some light on this problem, it would be greatly appreciated!!!

joneidy, THANKS BIG TIME for the work you do here!!!
