Need help un-bricking my G4 - General Questions and Answers

So I'm sort of a noob to rooting......always had phones that you could just use towelroot on and it worked fine. But I recently got a Verizon lg g4 and tried to use the low effort root method, did everything exactly as it said but somehow or another I messed it up and now I have a paperweight. The phone will not turn on, charge, or show any sort of life whatsoever, so I cannot get it into download mode. (otherwise I wouldnt need help lol)
The only thing it will do is when you plug it into a pc the computer will recognize it as a "unrecognized usb device", and if you hold the power button on the phone for a long enough time the computer will say it was disconnected and then reconnected. (phone still does nothing) If you guys can help at all or give me any suggestions it would be greatly appreciated
EDIT: I have the stock firmware/software for the phone downloaded on my computer so what I really need is just a way to get it onto the phone

And Im not opposed to tearing the phone apart if need be

Anybody

Did I post this in the wrong section?

bricked, soft or hard?

ok, i've been dabbling around with different roms, and have basically gotten the general concept of how to flash custom roms, using odin 1-click and what not.
well thats exactly what im trying to do now. i was in the middle of flashing my phone to a stock rom when all the sudden it said removed. i did nothing for this this to happen.
well, anyways, i was like oh well i'll just put in this here jig and restart the entire process over again. so, i put the jig in the phone, which takes me directly to dl mode. i removed the jig and placed me usb port into the phone, which is where the issues started. for some reason, my computer now wont recognize my phone, therefore making it to where odin wont recognize my phone. so like any other 20 year old male i say wtf and destroy my phone furiously.
not really, i actually removed the usb port and the battery, then reinserted the battery, and tried pushing the power button. after doing so, nothing. like literally nothing, yet when i put my jig in it takes me directly to download mode???
so pretty much im just confused as to whether or not my phone can be fixed via recognition from my computer, or should i say fml my phones hard bricked, and now i gotta do the insane bootloader thing or just complain to customer service about my phone?

if your phone can get into download mode its recoverable...any sign of life is not a brick... your problem now is your computer not recognizing it.
uninstall drivers,reboot, reinstall, reboot, switch usb ports making sure its one in the back connected to the motherboard, use oem cable that came with the phone...
so, the magic way to make it work again is simply to do nothing but what your already doing. lol.
i pretty much just got really agitated and started plugging the phone in and out of the computer, waiting on the unrecognizable thing to pop up, and BAM odin works outta nowhere and my phone is recognized. damned computers. lol

[Q] X10 Mini Pro U20i not turning on!

Hey guys,
So I rooted my U20i, then went to unlock the bootloader. Somewhere in the process of unlocking the bootloader, something went wrong, and now the phone is completely unresponsive. Like, nothing works. If I plug in the USB cable, the computer does not recognize it. If I try to power it on, nothing happens. It's essentially 100% dead.
So, what can I do? I tried using SEUS and the companion software, but it won't recognize the phone. As far as my computer knows the phone isn't plugged in. Can I purchase the DavinciTeam reflash? I'm really at a loss for what to do since I've never had a handset just completely stop functioning in every way before.
Thanks.
Every other time I've heard of someone bricking their phone, it has always still been recognized by their PC when plugged in, but this phone does not even get recognized. I'm really at a loss for what to do.

[Q] Desire S, USB not working but charges? Pls help.

Hi
I recently bought a Desire S from a friend. I went about rooting it but when I plugged it into my PC it is not recognised at all, literally nothing pops up on the phone or the PC.
I've checked the settings in the phone and USB debugging is enabled and I always changed default connection type.
I have even booted into Hboot and plugged the USB in, but still nothing.
The phone charges perfectly fine and I've tried plenty of different cables. My other Android phone works perfectly when plugged it.
I'm starting to think its a hardware issue, anyone else heard of this? common problem? any fixes?
Thanks
Re install htc sync and drivers, then remove sync and try again

I have the same problem, sort of. When I plug mine in all is well at first, but give the phone one tiny nudge (or just wait a few minutes) and it goes back to charge-only mode. It's probably a slightly loose connection somewhere in the USB port on your phone.
To be sure, try if it works in Linux. The Linux USB stack sucks infinitely less than what Windows uses.
Thanks for the replies. I tried Ubuntu but exactly the same (it worked with my Nexus 4)
Thats a little annoying, thankfully charging still works, just unsure how long that will last for! plus I cant root it! but I dont exactly need it rooted but I tend to do it anyway.
I've sorted it now. It was a loose ribbon cable, plugged that back in after taking the phone apart and its working.
Bootloader unlocked and custom recovery flashed. Ready to rock.

Note 3 Bricked?

I have an AT&T Note 3 SM-N900A. I Installed X-Note Rom on it a while ago, but I recently have been having problems charging the phone and was going to take it to an AT&T Device Support Center to fix it. I tried to install the stock firmware N900AUCBMI9 using Mobile Odin, only to see the a boot up screen that says "System Software not authorized by AT&T has been found on your phone . Please turn off your phone and go to the nearest AT&T store for help." I tried to get the phone to connect to Odin on my Windows PC, but the computer will only say USB Device not recognized, and it won't show up in Odin at all. The weird thing is that it says USB device not recognized even while the Note 3 is off. The phone also stays on while in Download Mode when connected to USB with no battery.
I was wondering if there's anything I can do to at least ensure that the people at AT&T can't power up the phone and see this message. I should have just left it on the custom rom, this looks way worse. I'd rather have a hard brick at this point, at least they wouldn't be able to see it was rooted and flashed. I really screwed this up, if I knew I'd be having issues I would have never rooted it. Any help would be extremely appreciated. Thanks for your time.

[Q] Need Help Unbricking D801

I have now learnt my lesson - never flash firmware onto a phone after 1am! A tired brain can make simple mistakes far too easily. In this case, I accidentially flashed a version of TWRP 2.8.2.1 meant for a D800 onto my T-Mobile D801. So now the phone just sits at the LG logo with the LED slowly pulsing diferent colours until the battery runs out.
I have now gone through every thread I could find on this forum, as well as other places, about unbricking G2s. I tried opening the phone and shorting the test pins, as shown here - https://www.youtube.com/watch?v=Muvcw5eVwH4 Visually not much changed on the phone, although now it seems to sit with the LED on red most of the time. I don't seem to be able to make it go into Download Mode, as it still sits at the LG logo (or is that normal with D801s?). I'm wondering if maybe I should try the shorting method again, but without rdisconnecting the battery this time.
Plugging the phone into a Windows 7 PC via USB, it installed two two devices, "LGE ANdroidNet USB Modem" and "LGE AndroidNet USB Serial Port". This seems to indicate that the device isn't quite totaly bricked.
Any idea where I should go from here? TIA

I had in fact tried several times unsuccessfully to use the method in that YouTube video to make the phone go into Download mode. However, this was not possible, as in this particular brick mode the phone never actually turns off. It stays in that mode until the battery runs out and then resumes in the same mode when there's any more charge in the batery.
I was eventually able to break it out of this mode by opening up the back of the phone and flipping up the battery connector (with the battery already charged). I then inserted the USB jack and held down the volume-up button, while reconnecting the battery connector, to power-on the phone. This trick made the phone go into Download mode and I was able to reinstall the stock firmward kdz file via the LG flash tool, as shown in http://forum.xda-developers.com/showthread.php?t=2432476
