[Q] LG G2 D800 ATT Download Mode no usb drivers install/com ports not recognized. - AT&T LG G2

Okay. I've got a LG G2 D800 ATT flavor. Someone had a custom recovery and did the kit kat ota that soft bricked it. YAY!
I've tried various methods of trying to get everything back to stock(LG flash tool etc)
Only I always run into the same problem.
I can get the phone into download mode. but the computer will not recognize it. Usuually when I put other G2's into download mode the computer will recognize it and start installing. Not with this phone.
Ive also already replaced the charge port thinking it was a hardware issue of some kind, but the problem persist.
Any ideas? I can flash the stock rom fine if I could just get it to be recognized by the computer. I've tried on 2 machines running 64bit windows 7 and I've tried on machine running windows XP.
Obviously I've tried USb 2.0, 3.0, different cables, different ports, different computers, and even changed the charge port out and still nothing.
Cheers thanks for looking!

Can you get into recovery? If you have twrp you can just adb sideload a Rom and boot up.

Hmm. I'm not sure. When I attempt to go into recovery mode it gives me the option to do a factory reset. When I click yes a "TeamWin" shows up and the script runs. But I'm not sure how to directly boot into twrp. Sorry I'm a little new to this. Here is how I tried to get into the custom recovery:
Volume down and Power until LG logo is displayed, then let go of buttons and repress them after a second.
Is that the correct procedure?

If Team Win recovery shows up you have twrp. What script are you referring to? It should just show a menu of things like Install,Wipe, Advanced, Sideload..etc..

help?!

ok.. i was on s7/hellraiser with infusion kernel. since running this rom, my pc no longer recognized my phone. i tried flashing a rom thru cm7 but got stuck on the samsung logo. after, i tried flashing back to s7 & infused, as they are both on my sd card, thru red CWM, but im still getting stuck at the samsung logo. my pc wont recognize the phone to odin back to stock so.... wat can i do??? plz and thnx
Did you try using Heimdall? Some have better luck with that. A factory data reset might fix your problem, because you seem to be flashing a lot of roms over each other. The bootloop might be fixed by a reset, if not try again with Heimdall. Otherwise I don't know what to tell you
Edit: Try using a different USB Port on the computer or even a different PC all together. Also try using another cord.

I would pull battery as you replacement e it hold three keys untilled cwm shows up then select factory reset /dalvik clear etcc and reboot

sounds like a driver issue. install ubuntu and use heimdall. that'll fix any driver problems
try pulling the batter and inserting it with odin open, the usb cable inserted, and holding down the volume bar. after that doesn't work delete and reinstall the drivers. or go with linux and never have a driver issue with the phone again ( may have driver issues with video and wifi and attached devices though)

in heimdall once you load all the files (no pit because you don't have bootloaders) click flash or start or whatever. if the phones isn't connected it will let you know.
there is also heimdall oneclick return to stock. set the. jar file as executable and launch in terminal. the thread on oneclick should explain the comand needed and how to install heimdall backend from inside heimdall oneclick (if you don't have it already.)
did you install the android SDK

unbricking help

alright so somehow in the process of flashing and going back to stock and what not I messed up my g2x and now I have no baseband or battery info and whatnot, you all know the story. Ive spent the last 5 days on the internet trying everything I could find to get it up and running again and I keep hitting a brick wall.. Yes ive searched and tried multiple things but the one thing that I cant get past is the kdz flashing, everytime, no matter what I do, it always gives me the phone not found error, the USB cable and port are fine and I have the drivers installed and everything. Ive tried on VM Xp mode and in Win 7 Ultimate and no luck. If someone can give me some help/support thatd be awesome.

You can use XP mode to do this, and yes the USB driver will detach. Just re-attach it and the flasher will kick right back in where it left off. I had to do this just twice during the procedure. As long as you stay on top of it you will have no problem.

cant boot out of recovery

cant get passed recovery. tried TWRP, CWR, STOCK all the same result. tried installing backups same thing.
any help appreciated.
tried lgupdater too. starts, checks sw version, says there is an update avail, then starts the updater, when it gets to checking connection with phone it says cannot communicate with phone."diconnect cable, take out battery retry" heh, irritating
What do you mean when you say all recoveries fail? What steps have you taken exactly?
Just asking duo we can maybe figure out the problem

To update via LG I found putting the phone in s/w update mode, then plugging it in to the computer, the most error-free way.
If everything fails look up the thread on restoring/flashing stock via nvflash. That'll work 100% unless you have a bad USB or bad drivers.

latest drivers from lg. good cable, tested
how would i put the phone in s/w upgrade mode before i plug it into computer. if i remove battery and hold vol up and down then connect usb it will go in s/w update mode when i start nvflash.
seems i cant start the phone with pwr + up /dwn vol buttons

Heimdall 1click stuck at kernel upload failed

Need some help. Step dad's Infuze is boot looing at the samsung logo. Searched and found qkster's thread about using heimdall 1 click to flash UCLB3. Got the phone into dl mode, loaded drivers and started flashing. Stopped at kernel upload failed. Ending session. Don't know what to do, can I just unplug and start over? Thanks in advance for any help.
Rebooted into dl mode, now it is showing firmware upgrade encountered an issue. please select recovery mode in kies and try again. Please help, is this still fixable?
I can get the phone recognized by Heimdall, just that it stops when loading the kernel. Is there another way to load kernel when in the dl mode?

Try running again and again if necessary until flashes and boots into ROM then Use one of the kernels in the same thread of qkster's that includes root and CWM recovery
Keep trying different ports, different USB cables, reboot computer,use different computer if available

either odin or heimdall works. you have to believe that. the frustration is getting a pc with usb port and a usb cord and your phone to align and work correctly. usually after a few driver install or java update or reboot..something works.
your other situation where you kinda had it recognized and almost completed a flash, try different usb cords. hold it steady, wipe the ports..etc..connection is prolly loose

Yeah frustrating it really is. Will fire up the old xp boxen and see if I get better results with that.
While reading up yesterday, I saw some posts about corrupted efs causing the att screen bootloop. Is there anything else?
I don't think it is a power button problem as the phone doesn't turn on when I insert the battery.
Finally, you think it is safe to use a custom rom if the stock one is bootlooping on the at screen?
Thanks again, will go back to reading and trying stuff after dropping off my son to daycare.

At&t lg g3 (d850)

I hope someone can help? I have an AT&T LG G3 (D850) that boots up with an error message at the logo screen. It does not go any further than that. I can get the phone in recovery mode only. I have reset to factory several times. No luck. Additionally, my computer does not recognize that the G3 is connected, so can't use Odin to flash recovery.
Is there any way to get the phone to work again? Or, am I looking at a very expensive paper weight. I thank you in advance is you can help me out.

Thanks for your help. The phone was rooted, so I am sure that AT&T will say that I voided the warranty. But, it does not hurt to try.
If it won't boot they can't tell doubt they will check anyway

Thanks for your response. Odin does not highlight a port, when the phone is connected. ADB says no device found. I think I will go to Best Buy and ask their Samsung Expert to update ROM, which might get it out of loop.
While in recovery you should be able to mtp xfer a stock rom to your downloads directory (SD card), and flash it, would be my hope. I believe you did say you can get to recovery.
What happened/changed that left it error booting?

Maybe I am using the wrong term...I can hold the volume button down and power button to get it to a screen where I can wipe the data to factory. Besides that I cannot get to any other screen. I was trying to flash Philz recovery on the device. Thanks for taking the time to respond.

Are you on OEM recovery? If on TWRP recovery you can MTP a file to the SD and flash via that. I'm not familiar with OEM recovery other than seeing it once.

First of all, thank you for all your responses. I really appreciate that. I ended up sending the phone to LG to be fixed. I just want the phone fixed and server as my backup now, since I bought the Samsung Note 4 and Gear S. Will update, when I hear back from LG. Thanks again.
Sounds to me that the drivers are not loaded correctly on the PC. If you can get to recovery you should be able to get to DL, I would think.
