Can you get it into battery charging mode ?
If you can get there, KDZ software will switch it to Download Mode when you attempt to flash firmware.

I am not sure as my boot animation is damaged no matter what mode I boot into. The problems began when I flashed a v20 baseband

radio image which is initialized before kernel is damaged
it doesnt interefere with bl or download mode however

- unplug usb cable.
- remove battery.
- hold vol - pressed.
- while doing so, connect usb cable.
- does it get into download mode ?
or try
- unplug usb cable.
- remove battery.
- hold vol - and + pressed.
- while doing so connect usb cable.
- does it get into download mode ?
let me know if either of those does anything.
If any of those work and kdz flash doesn't fix there's still hope, let me know how it goes, you might need a modified firmware dll aswell.
Good luck

No luck with odin.

Okay im running windows xp, and i have all those drivers installed...
http://www.userdrivers.com/PDA-Mobil...dows-XP-Vista/
and http://drivers.softpedia.com/get/MOBILES/Samsung/Samsung-Galaxy-S-USB-Driver-for-Windows-x86.shtml
so what am i missing to get my vibrant to be recognised by odin in download mode????
What are you running currently?
simply honey 3.6..... gingerbread
By chance did you forget to enable usb debugging?
idk, i flashed from a 2.2.1 rom to simply honey 3.6 through rom manager, but i did have it enabled through before i flashed for sure.... And usb debugging is not required for download mode as (i think) thats a whole different thing???
It needs to be enabled to use Odin. Also, sometimes for Odin to see my phone I have to unplug my phone and open Odin a few times before I finally get Odin to see my phone. It's very finicky for me, always has been

Go into windows device manager. Make sure that your computer is even seeing the device and that it has recognized the drivers for it. If it recognizes it, try rebooting computer then restart the process. Also make sure your phone is actually in DOWNLOAD mode. Not Recovery mode.
If you do not know the difference between the two, let us now and we'll assist further.
Happy hacking!
I use to always have trouble with Odin..then one day someone mentioned they always right clicked on Odin and chose "run as Administrator", I have never done that because I figured I was the administrator....but once I did it, never had a problem since.
Another problem I run into (well not anymore) is the USB port I plugged into. If I was on a hub or something it wouldn't work. If I plug right into my computer it works properly.
I also use adb commands to get into download and recovery when I'm Odin'ing. It also let's me know if my phone is detected by the OS.
#adb devices (should show your phone listed)
#adb reboot download (reboots your phone into download mode)
#adb reboot recovery (reboots your phone into recovery mode)
You'll need the SDK installed for adb to work.
Since I started doing these things, I have had ZERO problems with Odin and flashing my phone.
ay.. usb debuging was enabled before i flashed... now if my turn turns on it goee onto a bootloop... so everytime i cinnect my phone to the computer it says device not recognised. ohh and one thing to mention is that my computer doesnt have a highspeed usb port
Three button to download mode - power+vol up+vol down and see if you can get it into download mode then plug in usb (1.0 should work), then run odin...
otherwise i think you're looking at trying to make one of those jigs or replacing your phone...
try
1. Start Odin
2. Plug USB cable into pc
3. Power off the Phone.
3. Pull the Battery.
5. Plug USB cable into Phone.
6. Press and Hold: Volume UP + Volume DOWN + Power, all at the same time.
7. Re-insert the battery.
8. The phone will power now, when the screen starts a cycle of going to a BLACK screen, release ONLY the POWER button.
9. When you see the download icon release the volume buttons,
10. Odin back to stock by putting the PIT file into the appropriate area and the .tar in the PDA area.
Afaik the three button combo is for
Recovery mode. Follow the above directions up to the power button part. While holding both volume buttons, it should go directly into download mode when the usb us plugged in
Try removing all drivers then reinstall if xp doesn't pick it up
Beware of angry gingerbread man
power off phone
pull out battery
turn on odin
attach phone to pc with usb cable
now while holding down both volume buttons put battery back in.
now you should be in download mode and go back to stock with odin from here!
Enjoy and also make sure u have the proper samsung drivers
Install samsung kies mini. It gives you the correct drivers. I once installed those and it messed it up. So install kies mini.

[Q] Bricked phone?

Hi, I was flashing my LG when the flashing tool stopped at 63% and showed some error, i tried to flash again but it gave me error 502.
I turned off the phone and tried to turn it on again, the screen wont turn up but the PC detects the LG (zune doesn't).
I've tried to put it on emergency download mode with vol- + camera + power but the tool stills says error 502.
Is it recoverable or is it lost?
Update: I was able to recover it! I tried to enter emergency download mode with the battery out but connected to the pc, then i inserted the battery and the LG flashing tool recognized it!
Took 5 minutes to flash it. (I used the vol- + camera + power to enter emergency download mode).
Good to know and happy for you resolving your issue
bricked

Problem with LG Spirit: Secure booting error

Hi,
A friend of mine gave me his LG Spirit H440 with the boot error: Secure booting error
In his words he tried to update the software, the phone started to lag and after a reboot the error occurred.
The guy is simple user so installing custom recovery or rooting are out of the question.
Here is a video I made of the problem:
https://www.youtube.com/watch?v=fONioh6uNms
After removing the battery the phone starts for 2-3 seconds with Secure booting error and then powers off. After that it cannot start again until the battery is removed and then everything repeats.
I tried to connect it to the PC with Windows 8.1 and installed LG drivers, but nothing happens. It's not recognized.
Also tried to enter download mode with Vol Up and connecting the USB cable, but again it just displays the error and shuts down.
Is this soft or hard brick? I'll be grateful for any help and guidance.
Try to set it in "upload mode" and flash stock rom kdz

No I didn't manage to find a solution and no one was able to help me.
I returned it to my friend and he bought a new phone.
Sorry.
1. Power down the phone.
2. Connect USB cable to computer.
3. Hold Volume DOWN and insert the USB cable.
4. ??
5. Profit.
