[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.

[Q] Can not enter download mode

Sorry if this has been discussed before. I am not new to the rooting scene. But I am stuck on this issue
I am attempting to enter download mode for my Samsung Tablet 3 10.1 Wifi.
I am pressing the power / down volume combo and I get to the boot screen and let go. From here it goes right into recovery mode
I get the screen with the android and it says no command / error and stops there with the recovery options.
At this time I am on stock 4.2.2 and been trying to get this error figured out. I have searched briefly on here and googled other solutions but they all require to get into download mode, which I am having trouble getting to.
Any suggestions ? Or point me to a solution

Hi !
Thanks for the quick reply. I have tried that method as well and it still sends me to the recovery screen. Though I did manage to see a new screen that gave me a option to press volume up to continue and volume down to reboot. When I pressed volume up it just rebooted normally

Try to go into recovery. Turn off your phone and turn your phone on with the power button + vol down. When the phone turns on,let go and press the same combo buttons again for a few seconds until it shows a factory reset. Click yes for both ( no it won't delete your data) and it will take you to TWRP

ןIt's still not working and I tried it yesterday and now it does not work because it is installed on the device Recovery So how do I solve this problem please help me!
Thanks in advance.

LG G4 won't let me reset phone from recovery mode

Hi All. I am trying to fix a phone that is stuck on the LG boot screen. I have tried to put the phone into recovery via the volume- and power buttons. I get to the screen that says delete all user data and I press yes and get to the second screen to reconfirm the delete. I press yes and nothing happens. Does anyone have any ideas on what I can try next? I want to reset this phone for my friends son. I suspect he might have over heated it playng games. Thanks in advance.

no it doesn't have a home button , and nothing will stop it , what i noticed tho that if i hold vol down and the power button the next time the logo will disappear way faster but only once each hold and ill get a delay of 2 seconds before that logo appearing again and the phone rebooting , its been literally 62 hours since it started doing this , it started with a battery fully charged meaning a 5000ma , about that delay i tried using it but nothing worked , i tried clicking vol up and power button which is supposed to put the phone in recovery mode but nothing happens , i went as far as spamming random buttons to holding them for more than a minute , nothing stops it

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

Thank you for this post. I did this and my phone booted to TWRP. (I was flashing TWRP when I encountered the bootloop)
After booting to TWRP, I did an advanced wipe (I left System unchecked). After the wipe, the phone booted normally.
