You have to use volume up and down at the same time. So press both volume buttons and power button at the same time to get into the bootloader.

I understand that but my volume up button does not work. stopped working randomly about two weeks ago. Therefore I can not get into bootloader. Only odin mode. So once in odin I cant get odin to see the gnex. I imagine its the drivers but they seem to be installing ok. Anybody have any ideas or am i screwed? I also took it apart to see if i could see something wrong with volume up button. No luck

Do you have USB Debugging enabled in your settings? If so, boot your device (yes, I understand that you will only see a black screen, but it doesn't matter) and plug into your PC. Once it is fully booted, open a command prompt on your PC and type: adb reboot bootloader
Then you can get into your recovery and then follow the instructions here.

It was enabled before the issue. Thanks for the advise but t gave up trying to fix it. Its my company line so I just ported my number to a temp phone and awaiting a replacement from assurion. Cant afford it being out of service too long. Guess i will just start over. But this time no hardware issues so bootloader wont be a problem again.

[Q] Acidentally Wiped System, What can I do?

I accidentally formatted the system partition so the tablet will not boot. I can't get back in to TWRP, I didn't have anything to flash in there anyway because CM would fail. What can I do?
Thank you.

You could try the LG mobile support tool

Can you write to it in ADB? How far does it come when it tries to boot? just LG bootloop? And what edition of TWRP did you use to flash?

I realize why it didn't flash. Because I was using an older version of TWRP that wouldn't flash AOSP roms. Is there any way to boot to recovery from the device being off?
The method in the link doesn't seem to work anymore.

How far do you get in the boot? LG screen? When connect to PC do you get connect/disconnect sounds? Please answer the questions as I'm thinking about this. I can't find any key combos so we need to find out if we have a small window where we can talk to ADB.. Any connection sounds? How far do you get?
Are you familiar with ADB and Fastboot?

I don't hear any sounds. It just stays at the LG screen. I made it to the factory reset screen but it didn't do anything. I followed these steps:
Make sure your device is fully charged and turned off.
Simultaneously press and hold the power and volume down buttons.
When the LG logo shows up, release the power button only.
Now press and hold the power and volume up button while keeping your hold on the volume down button.
When the factory reset screen appears, release your hold on all buttons.
Press the power button to continue.
Press the power button again to confirm if you’re sure you wish to continue with the reset.

ADB doesn't work at the LG screen, I just get the error: device not found message.
I can just send it back but I'd prefer to get it working.
Thanks

Okay, okay, I dunno what you can do maybe ADB Works in here: Turn off the device AND disconnect from PC. When shut Down, you DONT hold power, but hold Volume up + Volume Down, when you hold both, you plug in USB cable. This takes you to download mode. That is perhaps a step in the right direction if you can start ADB from download mode. Then you can boot into recovery. But I don't know. This is maybe the last option for you. No recovery key combo has been discovered yet. If you can do a fastboot boot recovery from download mode, that would be golden. Then you can use the SD Card to get back with the newest TWRP and the CM11 nightly. Please let me know if this Works man. I'm sorry for your loss, otherwise. Factory Reset, as you said, will not work, since there's nothing to "restore" from. You deleted it. :/

Unfortunately, ADB doesn't work in download mode.

Damn that sucks. I was looking around the G2 forums to see about download mode and what LG usually did with it. Apparently they are using something called KDZ files, and they are able to flash stock roms back onto the device with something called FlashTool. Now, if it were my tablet and it was in the state yours is, I would try and read the tutorial. And then I'd follow it step by step but instead of the G2 KDZ, I'd see if I could find a KDZ with a G Pad rom instead. And just.. Yolo that ****.. From download mode.
Here's the thread, if you wanna read it.. http://forum.xda-developers.com/showthread.php?t=2432476. I dunno man. The LG Tool thing, maybe you should try and see what techrider6262 is saying, he might have an idea as well, otherwise, just go all out crazy and see if you can magically use the FlashTool on your G Pad instead of the G2, since they are from "same line up." I know that's not the same as same model and so on.. But still.. Download mode.. Is download mode. Ofc. the tool itself or the settings in the tool might not work.. But.. You know. Why not.. Can't hurt.. Download mode will prolly still be available afterwards.. "For science."

got the same problem. i couldnt i wiped all data on the tablet and couldnt select the rom from the ext.sd. now its stuck at the lg logo.

This guys.. Is for download mode fix. I am pretty sure this works. Since you have access to Dload mode. Good luck.
I use the download mode to install the original official rom.
1. Download the LG MOBILE SUPPORT TOOL by this link:http://www.lg.com/us/support-mobile/lg-V500-White
2. install the software in computer, Plug in USB cable with computer, Open the software LG MOBILE SUPPORT TOOL.
3. Turn off Pad and unplug.
4. press hold both volume up and volume down, Then plug in usb cable, And then pad is in downlaod mode
5. USB driver will be insatlled automatically
6. In LG MOBILE SUPPORT TOOL, click option---.country and language-OK, then click option--upgrade recovery
7. It will installe original official rom automatically.
8. After about 1.5 hours, The pad will be installed the last official room.
^ This is a quote and now I shut down the thread, sorry, don't know who said it, just got stoked when I saw it.

thanks, the tool is downloading the rom. hope its works.
// it worked thanks a lot, will try to flash cm 11 tomorrow again.

That is GREAT!
Now remember mate, clear DATA in TWPR, not system.. Never system. Clear only data/factory reset, then just flash CM 11. Nothing else is needed. Remember to install superSU from market after you get booted, otherwise root will not work. Update Binary in SuperSU.

Okay thanks for your help. Its so stupid that there is no key combination for recovery.
I will use your advice and try it later.

There is...
With device powered off do this...
Hold volume key down and press and hold power button.
When LG Logo appears let go of just the power key while still holding the volume key down and then press power key again and volume up while still holding down the volume key.
You get to the factory reset screen and just keep pressing power until you get into recovery.

You never stated what happened to get your device in the state it is and i'm just assuming you did something to brick it, so here
So firstly you need to get the drivers for your device installed.
my advice download WinDroid Universal HTC Toolkit v1.1. It will allow you to easily know if your pc is recognising your device.
Once that is done you need to get your device changed sufficiently.
Go to http://www.hackmyandroid.com/comprehensive-guide-on-unbricking-the-htc-one-x/4216 and follow the instructions.
Charge HTC One X in Fastboot Mode section from the link should help you charge your device
With the ADB folder where it should be on your computer C drive and your device plugged in and recognized, charging shouldn't be a issue
this should cause your device to restart repeatedly until it reaches about 10% battery
I advice once you have completed the charging of your device to the 10% mark that you continue on to the Unbrick the HTC One X as well as the Restoring the nandroid backup sections. You can always install a custom rom like CM11 or a sense based rom instead of doing restoring a nandroid backup
Hopefully your device will be up and running
Goodluck and let me know how it went.

Did you make a nandroid backup before you changed the dpi or before?
Because if you did then just turn off your phone and hold power and volume down and then when the LG logo shows let go of power and press and hold back in if done correctly a menu will come up asking if you want to factory reset your phone so click yes and then yes again to confirm and you will enter TWRP then simply restore your backup from there....
If i have helped then please leave a thumbs up.

This is the proper button combination.
First hold volume down then press power down
When the logo shows up, release power and then press power again.
Hope this helps.

Download mode not open for me :crying: :crying: :crying:

If you are stuck on Samsung Logo, connect to PC and press Vol Down + Power for 7 seconds. It will go to charge mode. Disconnect from PC and it will power off automatically. After that press Volume Up + Down and connect to PC while holding and you will enter download mode. It will ask for confirmation.

Useful. Works
