LG G2 D802 - Download mode not recognized - G2 Q&A, Help & Troubleshooting

So when i put the phone in download mode, nothing happens.. it's like nothing is attached to the PC. No unrecognized device in device manager, nothing at all..!!
MTP is working fine, LG drivers are installed on PC too. USB OTG works while in recovery too.
I am on a Win 8.1 operating system. My phone has a custom rom and recovery. Blisspop v4.0.1 and TWRP v2.8.7.1 to be exact.
Anything that could fix this Download Mode issue? I really wanna flash the stock ROM. Or should i go ahead and flash the flashable zip of the stock kdz?

1. Try a different USB Port, USB Cable or PC/Laptop.
2. Uninstall Drivers ,download & install latest drivers if Verizon use the Verizon drivers. (If you were previously on Stock lillipop you really need to do this)
3. if none of above helps try the Custom Zip file...

Maybe try a different os?

Team win recovery project mounting issues

As teh title says i am using v2.5.0.0 of this recovery rom for my samsung s4 device.
The issue is that i cannot mount my SD card whilst in recovery mode.
It never appears on my windows 8 machine when i connect my device in recovery mode.
I have all the usb drivers for my device installed and that is how i originally put a rom on it when i was running a stock rom.
Now that i did a wipe i obviously cannot mount my device on a normal running stock rom because its removed and i am trying to install a new one.
How can i access and transfer files whilst in recovery mode?
Do i need any additional drivers?
Still cant mount. i notice ond evide manager it says the drivers are missing for SAMSUNG_Android yet i have installed samsung kais!

Uninstall KIES and any other samsung usb installed utilities first.
Then download the official Samsung USB drivers for windows here: http://developer.samsung.com/board/download.do?bdId=0000000700&attachId=0000000001
After all the uninstalls are done reboot computer and install the official samsung usb drivers.
Once that's done reboot computer one more time and then your phone should and will
recognize your phone unless you have a bad cable or a non-functioning usb port in computer.
Good luck!

No USB connection in Downloadmode

Hello!
So, i downgraded my G2 to 4.2.2 (thru the current flashing method from this thread). It worked, but now i want to upgrade to 4.4.2 .kdz again with this tool, but i cant get a USB connection in download mode.
I already installed and re-installed the drivers (from the thread), but still no luck.
The phone is booting fine and i can boot into TWRP aswell, i just cant get a USB connection in downloadmode.
At the device manager theres something like "CDC Serial port"?! cant be installed.
Any clues?

[HELP] PC Recognized F320S in download mode as unknown device

Hi, you may all be so used to this, however, this is my first time. I rooted my LG G2 F320S and installed custom recovery (CWM). Well, I thought I followed the instructions to the letter. However, my phone is now stuck at the LG boot logo. Anyway, I am now just planning on going back to stock. However, after installing the LG drivers, my PC detects the phone (while in download mode) as unknown device. I don't know what to do. I tried to right-click the item in the device manager and update drivers, but window's can't find the appropriate drivers. I can't boot to recovery, but while in download mode, PC can't recognize the device? Anyone can help me out? It would be greatly appreciated. Thanks.
1. Uninstall LG drivers
2. If u have Windows 8, put it in mode which allows to install unsigned drivers, just to make sure (hold Shift and choose to reboot in this thingy on the right)
3. Plug it in with download mode and install THESE http://tool.xcdn.gdms.lge.com/dn/downloader.dev?fileKey=UW00120120425 drivers
Hi reas0n, thanks for your reply. I did follow your suggestion, however, it's still the same case.
Any help, guys?

[SOLVED] [Q] [HELP] Stuck in Download MODE

My LG G2 d802 is stuck in the download mode and has no recovery. It happened when i flashed Miui 6 by gtbluesky after full wipe of data and system. Previously it was on cloudy 3.2 . After flashing the miui it wont boot and is in a bootloop on mi bootscreen. I tried but cannot boot into recovery seems like it doesnt have a recovery.
However, I can boot into download mode but it is not recognised in ADB nor Lg flash tool. I tried flashing kdz with the lg flash tool but it wont detect the device. I tried installing various drivers to the pc and also tried two different pc with windows 7. However, adb wont detect the device.
Regarding the drivers, the windows installs all the drivers but fails to install the LGE Androidnet usb modem drivers. If i manually try to install it from the lg drivers, it would keep installing and returns an error of timeout period expired.
So, i am stuck in the download mode with a bricked device.
If Someone could help me with this problem, i'll be much obliged. Thanks
SOLVED
[SOLVED] I downloaded the .tot file for my phone and extracted .dll from one of the .kdz & flashed it using the lg flash tool . It flashed good and now my g2 is up and running. :good:

SM-A500FU can't be detected by a PC, booting into recovery boots the system.

Hello,
I have installed a custom rom (Marshmallow) for my SM-A500FU through the adb. Now when I want to install a different rom I have to either boot into TWRP and I can't do that because booting into recovery simply restarts a phone, or I have to boot into Download mode and install it with the adb. The problem is that when the system is running, the phone simply charges, no Windows notifications or devices appear and when the phone is in Download mode Windows detects that a device is plugged in but can't recognize it. I have all the adb drivers, KIES and all that so it's not a problem. Can I somehow boot into TWRP or make Windows recognize my phone so I can use adb?
Thanks.
before installing a rom, have you wiped system, cache, dalvik and data? If yes try with a hard reset and if it doesn't work, too flash stock firmware
Hey,
yes, I wiped everything, I have flashed many roms earlier and I believe I have flashed it properly. I have managed to get into TWRP so I can actually flash FWs. I have only updated my rom to the newest CW13 build there is for my A5. Is there any way to flash a stock FW (for example a XEO KitKat) without ODIN? I can only use ADB through TCPIP and TWRP, so there is no way for me to flash it through ODIN.
Thanks.
so, if you press power+home+vol- it doesn't reboot in download mode, right?
It does boot into the Download mode. The problem is that when I plug the phone into my PC in Download mode it says that the USB Device is not recognized in Windows with 'A request for the USB device descriptor failed' error. When I plug it in when the phone is booted normally into android, it just charges, Windows doesn't see it at all.

Well, you can't flash samsung firmwares with twrp. Try flashing another rom through twrp
Alright, I have tried to flash multiple ROMs. Currently sitting on a Lollipop. Nothing changed, though. On every single ROM the problem still persists. It's not a problem with the PC as I've tried to connect my A5 to a laptop with freshly installed Windows and KIES and it behaved the same way as on my PC. The cable is fine as well, I have tested it with my old SGS3, it worked just fine on both my PC and laptop. Frankly, I have no idea what to do next, I'm starting to think that the port is physically broken. It's weird though, as I can still charge my phone and there is a response when the phone is in Download mode, just that Windows can't recognize it.
Try with adb command "adb reboot recovery" if it doesn't work you can downlaod odin mobile from play store and flash stock firmware!
Do you have odin for windows ?

Yes, ihlf his device can boot he can use mobile odin. Have you tried with other PCs, just to see it isn't a problem of your pc?
In my experience usb device descriptor errors are related to the specific PC the error occurs on due to device driver conflicts, but if you get the same error on another pc then it could be the hardware.
I'd certainly be trying another cable first on a fresh PC.
Anyway regardless of all that you can flash the stock firmware with FLASHFIRE available on play as long as you have root.
