Bricked LG G2! Please help! - G2 Q&A, Help & Troubleshooting

Ok so I was trying to install CM13, so i read something on a forum (I think XDA), and installed this zip that I downloaded from the website then installed the zip from my custom recovery, and then restarted, and I could boot into CM13, but then I lost my custom recovery! (TWRP). When I try to go to the factory reset screen when the phone is off, I select all the Yes delete data stuff, because that's how I got into my custom recovery, but now it says secure boot error, certification error, etc. and just boots into a black screen. So the only option that I am stuck with, is i figured how to get it into the firmware update mode (download mode), but no custom recovery, and when I connect it to the LG Mobile Support tool, It doesn't say it is connected, I have installed the drivers like 3 times, and my phone keeps connecting and disconnecting from my computer (I can hear the ding sound each time it disconnects randomly and connects randomly. I have no idea what to do. Am I out of luck? Pleeeeaseee help!!!!
LG model D803 Canadian version, was running 5.1 CM12 just fine before until i decided to update and this crap started happening

[Q] LG G2 USB Not Recognized

Hi, background is this..
I have a D802-10C G2 that i rooted the stock 4.2.2 rom a while back using the post chinese method. Easy enough, all worked fine. no complaints. A couple of weeks ago i got offered the OTA 4.4 update, this failed due to the root. I then removed the root using the feature in super su. that seems to have worked as no apps or file managers etc could get root access. However, the OTA still wont work.
Now my problem is my phone will no longer be recognized by any operating system, on multiple computers. I have tried many ADB drivers, Windows 7 wont even detect the device, i've used every PC connect mode, USB debugging. However always the same result, it's as if i'm plugging in a blank usb cable into the computer. Nothing at all.
The only thing that does happen when i connect the phone to a computer is the phone starts to trickle charge. There is nothing detected in Device Manager in Windows 7 I've tried connecting in download mode, nothing. I've tried the LG support tool, PC sync. Nothing.
WiFi does connect to the PC suite fine BTW and other than that the phone is working perfectly. I've also tried connecting multiple usb cables on multiple ports.
I haven't been able to find a single case of the same problem in the week or so i've been looking. Hoping someone can help, i'm thinking i may have soft bricked my phone. I really do not think this is a driver issue.
Any help would be great. cheers

YOu can try checking the device manager or use other USB port on your phone.

The problem is not like the usual ones you will see about "computer not being able to see device" I don't think it's a driver or software issue, or if it is it's unlike any i have found in the weeks i've been searching the net for a solution. Here's why....
When i connect the phone to Windows 7 and 8 ( on 3 different computers) No hardware is detected, nothing in the Device Manager, no yellow question marks indicating 'Unknown Hardware'. Nothing, all it does is start trickle charging.
Now even with no ADB, or any driver at all installed, the computer should still detect the phone. Mine does not.
The same thing happens using OSX and Linux Mint 16 (again multiple computers) No devices or mounted or volumes shown at all. Linux terminal command "$ lsusb" does not list my hardware.
This is why i'm pretty much convinced that there is something wrong with the USB port on the phone. Because, if Linux can't see it then surely it's a hardware problem right?
The only other thing i can think of is, i have messed up the phones firmware while trying to unroot it? but only because the timing of all this is just too uncanny.
I think i'll have to suck it up and admit defeat here. Funny thing is the phone works perfectly and charges fine.
Stuck on 4.2 , with no ADB functionality. Perhaps i'll sell it cheap to someone who doesn't care.
Cheers for the reply mate.
Same problem here!
Only my G2 is not rooted, it is still on factory OS and recently updated to 4.4.2.
I have tried on several computers, different ports and no help.
On the first connection to a PC not connected before windows reports "USB device not recognized" problem.
After that every time I connect the phone to the same computer the phone itself only recognizes that it is using USB charging mode, it does not recognize the computer connection (known by the USB ison on android system tray) even with "Ask upon connection option checked".
Even when I manualy change the Android mode in Settings --> PC Connection from MTP to PTP or even LG software, nothing happens.
Definetly there seems to be a problem with the phone, but I don't beleive it's a software but a firmware problem.
Please help if anyone knows what to do.
same thing happened after installing T-mobile rom thrugh twrp. but my device boots into fastboot and i tryed falshing :
laf.img, boot.img, aboot.img, recovery.img, laf.img
but after reboot my LS980 dissapear from device manager and stucked on LG logo.
Dont know what to do now.
I'm no expert, but given there are a lot of them here and none have weighed in on this with any ideas for a fix, i'm going to assume it's a hardware problem.
Anyone else agree? Hardware problem not software?
Cheers
I guess that you already wiped everything right? Apart from that, i'll suggest you to go to some tech supp and ask them if they can verify that each pin of the micro usb is properly working.
Sorry for my english, hope it helps!

I will try to check the connector although i dont think that it is a hardware issue.
BTW I can enter the download mode after flashing the mentioned partitions and i can also enter the stock LG recovery but when i do the factory reset it keeps showing Factory reset processing ... for ever
It has happened to me the same thing :crying:, and is a problem with the boot.img, if by chance your G2 version 4.4.2 and the the 4.2.2 boot.img, goodbye.
The only solution is to take it to repair a service official, there will change you the card, with the consequent change of IMEI.quent change of IMEI.

Sirs, I flashed the baseband (https://www.androidfilehost.com/?w=files&flid=12880) then it got working back.
solved for me
I have some kinds of that problem, let try:
Settings -> General -> PC Connection -> Select USB connection method -> Media device (MTP) (or whatever)
Got this same issue after flashing cloudy g3 rom. Then later flashing dirty unicorns, which requires jelly bean baseband. But even restoring g3 and 24a baseband, still doesn't work. No pc tethering and no on the go usb. My usb port is basically charge only.

I have a LG G2 . recently updated from vs98027a to vs98039a 5.0 lollipop. Since the update my computer won't recognize my device in download mode and I don't have superuser ppermissions. Help plz
I also have the same problem.
It happened when I tried to backup info through LG PC Suite: the phone disconnected during the process, and now it's not recognized by any PC (http://forum.xda-developers.com/lg-g2/help/lg-g2-recognized-windows-backup-t3155323).
Also found a description of the same problem here: https://www.reddit.com/r/lgg2/comments/2urpnw/lg_g2_usb_only_charging_not_recognized_by_pc/ - no solutions, too.
Did anyone manage to fix this?

[Q] LG L5 E610 bricked

Hello. Few months ago I installed unofficial Cyanogenmod 11 on my E610. After updating baseband it worked perfectly. After some time I decided to restore my phone to the state after installing CM11. It worked no problem. Today I wanted to do the same, and after installing SuperSU and Texdroider DPI I rebooted my cellphone, and it stucks on the cyanogenmod boot logo. If I try to get to recovery mode it stucks on the LG logo instead of CM. Hard reset is not happening at all. I tried to connect my phone via LG User Support Tool and install kdz firmware, but no luck. Although when I connect my phone without the battery to my PC i hear the "ding" windows sound, and phone exists in device manager. It also creates some disc drive in my computer, but unfortunately it's empty. I think textdroider has changed the build.prop file, so the cyanogenmod is not able to start at all. Is there any possibility to get to the build.prop file and change it, so phone will start? Or maybe somehow I can reset my phone or reinstall firmware using my USB cable without entering usb debug or recovery mode? Thanks in advance for any idea :crying:
Put your phone in Emergency Download Mode : switch it off, hold volume down button while plugging USB cable (already connected to the PC).
Then use the Support Tool to go back to LG ROM

in these cases emergency mode should work
removing battery sim sd etc... connect your phone to the pc throught us cable pressing vol- it automatically boot into download mode and you can easily use kdz.
make sure you have the last driver from lg websites else kdz wont find your phone, and set emergency option in kdz everything else it similar to a normal flash

Check if you are able to access download mode.
If not, check if you can go to recovery.
If both fails, then follow this guide : http://forum.xda-developers.com/showthread.php?t=2582142
The battery. BTW you don't need the otg USB you can use adb command while on twrp.
Oh yea the twrp used many layer of locking you need to swap again and again

Android boot loop on Samsung Galaxy Grand Neo (i9060)

Hey!
New to XDA but a complete fan of the help and guides you guys provide.
So, I acquired an i9060 smartphone and successfully installed CM 11 without the help of my laptop since the usb cable through Odin never worked for me (driver issues on Win10?).
Unfortunately, my phone entered an Android boot loop. And now with a lot of attempt I can't even enter CWM or even charge my smart phone, as it always reboots while trying to charge the battery (it's always drained) or gets stuck during logo before accessing CWM.
I tried to install Samsung drivers, Kies, ABD, Odin to restore the firmware but... nothing seems to recognise this Samsung device. Does anyone had the same problems I'm having now? Any suggestions?
You might try another USB cable, USB port, or even another computer. Without Odin, you're not going to be able to fix this since recovery is no longer available.

Tried on 3 laptops but the problem persists. Never thought of changing my usb cable though. I'll give it a shot
Btw, is there anyway to use an external SD card to force a factory reset?

Have you considered the possibility that your power button is sticking? Not the part that you touch but the hardware switch behind it?
Do you have USB debugging enabled?
Are you using the stock cable or at least a USB cable with the same number of pins/pinouts?

Galaxy s4 i9500 doesnt connect to pc. Stuck in bootloop. No recovery or safe mode.

Okay so here goes. I've looked at the forums searching far and wide for anything that may help.
The problem is I have an S4 that had some battery problems. (swollen) so i replaced it out for a new one. The shop that I bought it from claimed that it was an original replacement battery (I live in Pakistan so finding an original battery was hard for me). So the phone worked fine for about half a month and now it's acting weird.
1. It seems to be stuck on a boot loop. but sometimes will start and run for a few minutes (random amount of time) and then go back into the reboot phase.
2. the phone does not go into recovery mode. The recovery screen pops up for a second followed by a no command screen and then phone goes back to boot loop.
3. the phone doesnt go into safe mode either. So i cant check if its a app related problem.
I tried to then flash a new recovery or the stock rom. The phone doesn't connect to odin/ nor Dr.fone for android.
-> Windows doesn't install the MTP drivers even though i have the latest version of KIES installed.
-> I have checked with a replacement battery the problem still persists.
Please HELP!!
Boot it into download mode, then try connecting it to a PC.
@GDReaper
The phone goes into download mode but the computer doesn't recognize it. It doesn't connect to odin and it says mtp drivers aren't installed..

Did you install the Samsung drivers? Windows won't do it by itself.

Then try a different USB cable.
Try a different USB port, different computer, and different OS.
