FastBoot Mode Started udc_start() AnDroid Error

Hi Frendz,

So you have been Flashing your Android phone a lot...If yes then you must have surely come across a situation (I Hope Not) where the only thing displayed on Screen is like the one below...

fastboot mode started
udc_start()

And the below message while connecting the USB :-

fastboot mode started
udc.start()
-- suspend --
-- reset --
-- portchange --
-- reset --
-- portchange --

Tip :- Always keep USB Mode Debugging enabled on your Android Phone.

If this is the case then don't panic, Here's the trick to Fix it on your own.

-> Have created a separate post with an easier tutorial to fix the Fastboot issue. Check it Out !

Pre-Requisites :
1. A Windows PC
2. AndroiD phone (Ofcouse) & itz USB Cable.
3. Android SDK.
4. JAVA Platform (JDK)
5. ClokworkMod Recovery.

Note :- Make Sure you have LG Drivers Installed in your PC...If not Download B2C from Here.

Steps To Be Followed :

1. Firstly download Android SDK & JDK (If not Pre-Installed) to your machine & install It.

2. Now unzip the ClokworkMod Recovery downloaded from Step 5 & copy Recovery.img file to the following path - ..Program Files/Android SDK/Tools.

3. Check whether fastmode.exe & AdbWinApi.dll files are available in the same Tools folder (Most probably it will not be Present). Download the same from below Links.

Download: fastboot, AdbWinApi

4. Now connect your Phone using USB Cable. You should be able to see the messgaes like (suspend, Reset etc). Open Command Prompt (cmd) & enter the below commands in the same order.

fastboot erase recovery
fastboot flash recovery recovery.img
fastboot reboot



5. Usually after entering the 1st command Command prompt gets Stuck with message "Waiting to connect" (This Happened to Me). If yes..Try the below...

- Install the Drivers again from B2C Application & try again.
- Try from Different Machine preferable Windows XP.
- Download PDANet & Install the Application (Let it Install the Drivers) & try again.

6. If you were able to successfully execute the above Fastboot commands you would be now in Recovery mode.
That's it Flash a new ROM from your SD Card & Enjoy !!!

      Hi David,
      U need to flash a ROM once the fastboot issue gets resolved, Seems like Debugging is disabled in your phone cos of which ur phone is not goin into recovery.
      BTW for recovery mode u need to press the Power+Vol Down+Home button (incase u own a P500).


      Suggest u access the below link, download Android Flash recovery tool & follow the instructions in the post.

      hi admin,
      yea my device is P500 and I've been following the step with the link that you gave me, and since i can reboot my phone with that combination button so i able to enable debugging mode, and try again to fix the fastboot.

      but it's still the same, fastboot can't be fixed after i type fastboot reboot, it come back to
      fastboot mode started udc_start() :(

      maybe i just try to flashing other ROM because the stock rom and cyanogen is not working the volume and home button is error.
      or Time to change a new device Lol.

      Thanks for your help and the tutorial :)

    Hi,

    I am facing the same problem. But I am not able to understand what to do. I installed PDANet but was unable to understgand its function. B2C is exclusively for LG phones.
    And that waiting for device is not going.

    Please help.

      Hi Subhomoy,

      PDANet downloads missing Drivers during installation, Did you get the popup for downloading the Drivers & did u accept it ?

      Suggest you try an alternate approach to fix the fastboot issue, Check out the below link.
