[Q] D802 Bricked, computer won't recognize it - G2 Q&A, Help & Troubleshooting

Hi,
I recently updated to the official 4.4.2 kitkat update.I then proceeded to root the phone, and then stupidly, installed CWM. I rebooted, and was greeted with an endless LG Splash screen. Now, I tried a HEAP of ways to restore to stock, all of them returning the same problem, my computer won't pick up my phone. In download mode, nothing happens, nothing in device manager, and same when I'm stuck on the LG splash screen. When I go into CWM, it then recogizes my phone, but the methods of restoring to stock won't work with CWM running in the background. CWM also won't let me mount the usb...
The methods return the same error: Phone not detected, please plug the USB cable and retry.
Ubuntu won't recognize the phone in all three modes, and another computer does the same thing. (Both Windows 8)
Methods of stock restoration tried:
-KDZ
-LGMobile support tool
-Ubuntu (This: http://forum.xda-developers.com/showthread.php?t=2582142)
Can anyone help?

Install http://forum.xda-developers.com/showthread.php?t=2588979
then go to recovery and try adb devices on command prompt on your PC to check if your device is listed
if it shows your devices then just search any thread that tell how to push flashable rom to your device.

Was your phone able to connect to the PC afterwards? I have a D800 that I am unable to get any PC to recognize. I need to restore it to stock but no matter what I do it does not show up in device manager (and I have a working rom on it).

Yes, it does work now. I was able to restore to stock by adb pushing phillz recovery, and then flashing that, then adb pushing the stock ROM. Everything works as it should, now.

Does it recognize your phone when it's in the custom recovery? That was the only way I could do it on my phone.
Good luck!

I tried ADB devices nothing came out.
I have the same problem as listed in this thread. Tried everything to SHort circuit the chip. Basically everything.
I think the last thing i haven't try is dump it into the bin.

Nexus 7 stuck on fastboot screen/bootloop...bricked?

Hi
Tried to flash a new kernel and all seemed ok (flashed phones and nexus 7 few times now) when I came out of flashing I hit a bootloop, I though nothing of it and tried to restart....same issue, so next I tried to go into cw recovery, no joy, it will not show again.
I can power/vol keys to android fastboot screen with start power restart boot and so on but if I choose recovery nothing happens, I am stuck with either a bootloop or stuck on android fastboot screen and not able to move from either.
I have tried the toolkit and most other things but the problem is it cannot see my nexus 7, even after installing drivers and so on the toolkit (top right) does not list my nexus as found, because of this I cannot reflash any stock firmware/recover/reflash cwr.
Not sure how I can get around this if my pc cannot see the nexus 7.
Thanks for any help

Hi
I cannot flash anything. On the fastboot screen I can scroll up and down powr off/start/recovery....if I choose any (apart from power off) nothing happens.
When I hook it up to my pc it cannot see it, nexus 7 toolkit also cannot see it, it does not list it as found so I cannot flash anything on to it, if I try it just says waiting for device, tried other things and same thing either waiting for device or asks if fastboot installed.

You are already at the bootloader screen. Use your computer to fastboot flash a new kernel. Being able to get into recovery has nothing to do with it. You screwed it up flashing a kernel. Its likely thats all you need to fix it. Flash a new one with fastboot.

How did you get it to work? I have problem getting my device to be recognized. Stuck on boot loop too..
Hey man, how did you get your computer to recognize your device? Would be great to finally fix mine as this is the same exact problem -- computer doesn't recognize it even though in fastboot.

I don't understand exactly what you are trying to do, sorry: you said the pc does not see the nexus, "even thought in fastboot".. If you say even thought, it seems to me that you are able to access Android itself or maybe recovery? In that case I can't see the issue.. Sorry my fault, non english mother tongue
But, if have the device soft bricked and you are able to enter ONLY the bootloader (that is what we call often fastboot), then you should start to remove the not working fastboot drivers installed into your PC: launch the nexus in fastboot mode, go to Device Manager into your PC and search for a driver with an yellow exclamation point. This issue is very common so I hope that you have it, too.. So, uninstall that driver, then unlink the nexus from your PC; after a few seconds attach it to another USB port and see if Windows install a driver (it should). If this new driver doesn't work, too, or if Windows does no install any, try this one: http://forum.xda-developers.com/showthread.php?t=1426502
Hope it helps, let us know, see you!
EDIT: also, if you still have no luck, you should find a Linux or Mac PC/laptop and download the adb/fastboot binary files for that OS; this will definitively solve your driver issue ( @#ò#@!"@# Winzozz )

Hi sorry for not being clear. Basically I am only allowed to access the bootloader and my device is soft-bricked. I'm pretty sure I tried uninstalling and reinstalling the drivers about a year ago when I originally did it, but I'll try again and let you know. Thanks!

Same issue here. My pocket got warm earlier and i pulled out my phone and it was in CWM. Rebooting only brought it back to CWM. Phone is not recognized by PC (with correct drivers) and I can't get into download mode at all. Was able to flash TWRP through CWM because i had a zip of it on the phone. But even with TWRP, every reboot to... option just takes me back to recovery.
Install pdanet, while phone is connected in recovery mode to pc open pdanet and install lg drivers through it and then open adb in ur pc and type adb devices and if it sees then open sideload in twrp or cwm and push Rom to phone.

[Q] Help with Bricked LG G2

Hello Everyone,
I've been looking around and can't seem to find any guide I can get to work.
A couple months ago, I rooted my LG G2 and installed Cyanogen mod successfully. After a couple days, for some reason I restored to a backup I made back before I installed Cyan, so it was just on the Stock OS. A couple days later my phone tried to update itself and it bricked it. I was an idiot and wiped everything for some reason so theres nothing on there but the LG logo and then it goes to TWRP.
So now I'm not quite sure what to do. I can adb push and sideload just fine, but I've tried pushing a zip with the stock OS and installing it but everytime it just says it failed. Ive also pushed cyan on again and it says successfully installed and then just goes back to TWRP again. Can anyone help me with what to do from here? Do I need a certain tool to re install the OS? Will pushing it and then installing it with TWRP not work?
thanks!

Right click - Run as administrator.
Or do it manually
https, window enabler..etc.
Alright, so I was able to do it manually, but in the instructions it says to enable usb debugging. Just to clarify my phone is basically stuck in TWRP, so will this even work?

That's ok.
Open cmd line where your adb is. Put some rom inside.
Let's say the rom is : mycoolrom.zip
adb push mycoolrom.zip /sdcard/mycoolrom.zip
then flash it.

You didn't mention download mode.
Try powering off the device, hold volume up and connect to pc ?
Is the download mode at least working ?

Nope, no matter what I do it just goes to TWRP
And just to be clear it pushes over fine, and the zip is on the phone, its just when I try to flash it on TWRP it says failed. the last error code just said unable to open Zip

[Q] L01F no download mode, no usb reading.

Hello. Please help me. I have a Japanese version of G2 (L-01F - DoCoMo) and i tried to flash an european version of kitkat because i couldn't update in OTA. Now the phone is bricked, it is bootlooping, the Download Mode doesn't work, it shows a few of blue dots and it stays there (the phone can't be recognized on PC using the USB cable). I can enter the Recovery Mode (the grey screen with LG logo) where the phone can be read by PC and using ADB tool is shown as "recovery". I can't use fastboot.exe because the device is not being recognized. What can i do? Thank you very much.

Actually i'm trying to repair it since October 2014. No-one knows the solution. I went to 3 different GSM Services and they don't know what to do...
So...when i'm trying to put it in download mode it stays like this and the PC doesn't recognize it.
The only way to connect the phone to the computer is to put it in recovery mode (Backup & Restore) by holding Volume Up and Power Button at the same time with the phone turned off. It should appear something like this. The PC recognizes the phone but only in ADB. Look.
The third possible screen, which also is useless is this by typing in the CMD the following: "adb reboot recovery" (click). Here, the PC doesn't recognize the phone too.
Fastboot doesn't work.
And that's my problem. I don't know what to do.

You need flash required partitions (like aboot and laf) to boot phone to download mod. Then, you can install stock ROM from LG Mobile Support Tool.
You should take a look at here;
