Hard reset/Cold boot
1) Turn off the device
2) Press camera+volume rocker+power button(together)
Emergency Mode:
Why?
In order to use the following method http://forum.xda-developers.com/showthread.php?t=1508150
Read the above guide to understand what i mean. Then come back here. Then execute the above guide
You must enter emergency mode. Althoug everywhere it says to press power+volume+camera, for some reason that does not works for me. SO for others like me do the following & save yourself a lot of time
1) Turn off the device
2) Press the hardware keyboard space key+power(together). The LG "LGDP2_V36_UMTS.exe" will then be able to find your device on the available port.

Hey Everyone,
I just wanted to share something new I found out about android today, and probably a feature in ICS and JB only. Its not mentioned often but its simply being able to boot into Safe Mode on Android just like how you would enter Safe Mode in MS Windows.
Sometimes we tend to download and install 3rd party apps that we may know little of, and which may cause sudden Force Closures or freeze the phone a few seconds after booting is completed. Now, instead of having to format and reflash the ROM and go through all the trouble. Why not just enter into the Safe Mode which effectively disables all 3rd party apps including ones that are the main culprit? Once in the Safe Mode you may simply uninstall the app that's causing trouble and restart.
There are 2 methods that I know of to enter Safe Mode:
Method 1: (This method doesn't seem to work in Samsung roms)
1. Just after Normal boot is complete, immediately Hold Power Button
2. When Power menu Opens up, tap and hold the Reboot for a few seconds
3. You will get a dialogue asking you to reboot into Safe Mode
4. Hit Yes and your good to go!
5. To exit Safe Mode simply reboot your phone normally.
Method 2:
1. Fully turn OFF the device
2. Hold both Up and Down Volume keys and simultaneously press the Power Button to boot.
3. Release Power Button but keep holding Volume keys until boot is complete.
4. To exit Safe Mode simply reboot your phone normally.
Its that easy! Now a few of you may already know this so hats off to you. But majority of the users here dont, so pat your back for learning something new today
If you find this post helpful please feel free to hit the Thanks button:good:
Thanks it's always a good thing to know! :good:

Good info.
i'll save it, may be someday i need it.

Sorry for late response i was answering an pm First follow that download mode thing, I will later post the fastboot way if download mode doesn't work for your own safety cause fastboot is also dangerous :good: If you can't enter download mode at once, Try it several times.

I flash it trough flashtool and i installed a new rom and its fully working now , thanks, i also managed to save the photos because some google service backup all the photos and videos i had in this phone
@wazowpt thats sounds good have fun with your g2 ?
Okay, first off, I know there are threads about this, but none of them were helpful on my problem. So if you're having the same issue and it worked, don't forget to hit the thanks button! This isn't a very well made instruction, but it'll suffice. I haven't seen this method, so I thought I should share it.
Device: LG G2 AT&T D800
- I assume this may work on all the other variants as well
Issue:- Device won't boot to Download Mode even when doing VOL Up + USB, and my android system has crashed/force closed
Solution: (Warning: this is very tedious and annoying so put up with it like I did)
1. If your phone doesn't have USB debugging already enabled, go ahead and do so
- This... I had to press quickly to get to the Software Tab and tried to simultaneously click OK while trying to turn on Developer Option.
2. Install ADB if you haven't already. Run adb as Admin, type in adb reboot fastboot
- You should then boot into fastboot with a bunch of small white text saying some fastboot and shizz
3. Go ahead and hold the power button, at the same time holding the Volume Up button
4. DOWNLOAD MODE should come up
5. You can now restore your G2, You can look up the files somewhere here in the forums to restore.
Good luck, enjoy, say thanks, click thanks.

[GUIDE/FIX] {S4-MULTI} No Sound &/ WiFi &/ Bluetooth After Unbrick/Update? Read Me!
THIS GUIDE CAN APPLY TO ANY MODEL, PROVIDED YOU ENSURE TO GET THE PROPER FILES FOR YOUR VERSION!
I've had success myself flashing stock firmware from the M919V for Wind Mobile onto my I337M with no issue. This shouldn't be an issue. However, for the purpose of this guide, it is important that you get the firmware that was intended FOR YOUR DEVICE!
---
First head over here >> http://forum.xda-developers.com/showthread.php?t=2559693 >> and check out the original thread that helped me get to this resolution. Thank you to all the lovely people there!!
Before my softbrick occurred, I had flashed the NE1 modem through ODIN. I found that the same modem remained regarldess of the firmware I flashed. So I thought to match them up and give it another go. This worked great. This will work even if it was a regular S/W upgrade or install that caused the no sound and/or WiFi and/or Bluetooth issue.
Quick note before we begin: this guide assumes that you already went through a softbrick and have successfully come back from it, or went through a software update/firmware install which resulted in the same issue. Some of the steps in this guide may be able to be applied to some parts unbricking a phone, but this is NOT the intention. The intention is to help recover sound, WiFi and Bluetooth AFTER a successful unbrick or failed update/install otherwise.
DISCLAIMER: I am not responsible for your phone melting, imploding, turning into maple syrup or dying. Follow at your own will!
PRE-GAME CHECKLIST:
- Determine the ORIGINAL FIRMWARE that came on your device (this one was important for me, not sure how crucial it may be for others) - to be honest, I'm not 100% sure how to figure this out other than looking at the phone's box. It should notate which software version (SW-VER) it is. Before doing this, I was soft bricked, and had to use the very original 4.2.2 software for my carrier to recover from THAT. So maybe this part wasn't as important as I think, but I wanted to mention it anyway.
- The ORIGINAL USB cable for the phone - I suspect any high quality ones would work, but the one that came with the phone is a no-brainer
- ODIN 3.xx (I used 3.09)
- Samsung USB Drivers installed properly
- NO SD CARD (to be safe - this is optional as it should not be touched throughout the process)
- DO NOT, under any circumstance, use a USB hub for this procedure. Make sure it's direct into your computer with no extensions. I also recommend a cable that is 6ft or shorter if possible, but the quality of the cable is the most important
DO IT:
1) Download the ORIGINAL firmware that came with your phone (if you weren't able to determine this, I'd say the most recent one should be safe to flash, unless you softbricked while on 4.2.2 or 4.3 - in that case I would stick with the corresponding version, though I'm not sure how it would be affected since I didn't run into this)
2) Extract the file (I use 7Zip) and ensure there is one .tar.md5 file as a result - do not extract again
3) Boot up the phone into Download Mode (PWR off completely, then hold VOLDOWN + HOME + PWR together until the warning appears on the screen - click VOLUP to accept and proceed)
---PHONE WIPE---
This part is optional but I highly, highly recommend it.
4a) Flash Philz CWM (you can find the file and instructions on how to flash it through ODIN very easily)
4b) After flashing, it usually reboots into recovery. If it does not, do so manually: turn off the phone completely (hold the power button until the screen goes black) then quickly press the VOLUP + HOME + PWR buttons. When you feel a vibration, release the PWR button but KEEP HOLDING VOLUP + HOME. Keep holding those two until you see the phone turn off and come back on.
4c) Make sure you close ODIN once confirmed the flash is done
4d) Tap factory reset and confirm it
4e) Once done, choose the clean ROM install option and confirm that as well
4f) Reboot the phone and continue on with the steps
NOTE: if there is anything to backup, now would be a good time to do this.
---
5) Open ODIN (IMPORTANT: In Windows, right-click and choose "Run as administrator" - this helped avoid an error for me)
6) Connect your phone directly to a USB on your PC and confirm that ODIN recognized it (it should highlight the first box and have "COM#" listed)
7) Click the second section (AP / PDA) and choose the .tar.md5 file you got in Step 1
***NOTE: ODIN may look like it's freezing or hanging here - IT IS NOT, BE PATIENT - it is a large file and it will take a bit of time to verify the MD5 for it
8) Click Start and sit back - it should take 8-10 mins or so (8:55 for me) with KitKat, and 5-7 mins or so with JB.
9) Your phone should have rebooted into a fresh Firmware. If you hear the Samsung boot sound, GREAT! You should be good (test WiFi and Bluetooth if possible) and you're done. Assuming that's not the case, which is why you're here, proceed to the next step
***If it's stuck in a bootloop, you need to force Recovery mode and do a factory reset. To do this, turn off the phone completely (hold the power button until the screen goes black) then quickly press the VOLUP + HOME + PWR buttons. When you feel a vibration, release the PWR button but KEEP HOLDING VOLUP + HOME. Keep holding those two until you see the phone turn off and come back on. Use the VOL buttons to scroll to the factory reset option, and choose PWR to select. Then confirm on the next screen. Once that's done, wipe cache in the same way. Then, reboot, again in the same way. Now your phone should boot up
10) Go through setup and then go into Settings > More > About device. Observe the "Baseband version" section, and see if it matches the "Build number" section (starting from I337 and onwards). IF THEY MATCH, then repeat steps 5-10. IF THEY DO NOT MATCH, continue.
11) Download the matching modem file - ENSURE that the version of the modem you download MATCHES EXACTLY with the "Build number" in your phone's settings. Flash the file in ODIN in the AP / PDA section (if you need detailed instructions on this, it's a snap to find in XDA or Google)
12) Once done, reboot into the regular OS and verify that the "Baseband version" and "Build number" sections MATCH. If not, try to flash the modem again. After this has been verified, go ahead and follow steps 5-10 as many times as necessary until you hear that beautiful boot noise! It took me twice.
All the best and happy flashing guys! I'm not too much of an expert, just very good at explaining things, but I'll try to help as I can with any questions!

Getting Out
So I am gonna explain how to get out of it first.
1.) Hold Down Power Button
2.) Plug in the micro-usb to the computer well holding down the power button.
Done!
Getting In
This is how you get into download mode.
1.) Push the volume up and down at the same time. Do not stop until it boots into download mode.
2.) Put the micro usb into the device and you should see text saying something to the effect of entering download mode.
3.) Once you are in download mode you can stop holding unto the volume up and down keys.
Done!
Another way of getting into download mode via terminal.
REQUIREMENTS: ADB NEEDS TO BE INSTALLED FOR THIS METHOD TO WORK.
adb reboot download
What you can do with download mode
Download mode can be used to fix your device if there is an issue. An example would be not being able to boot up the OS. That can be fixed in Download mode by putting the stock OS back unto the device.
Download mode can fix MOST bricks unless it is a hard brick where the file known as "laf" has been deleted. In that case download mode won't help you.
Extra Notes
I am not responsible if you brick your system. Please use download mode and any other android feature or modification with caution.
