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?

Hey everyone I'm quite new to android, and I'm currently stuck in Download Mode after trying and failing to install Twrp
I was previously Rooted, tried to install Twrp via Autorec, however when I ran the app it soft-bricked my phone and put me into Fastboot mode.
I followed http://forum.xda-developers.com/show....php?t=2476972 method, and got back to Download Mode.
I am currently in the middle of returning to stock through http://forum.xda-developers.com/show....php?t=2432476 using the .TOT method.
I'm fairly close to repairing it but my only issue is that I cannot get my computer to recognize my phone. Neither in Device management nor adb devices anymore.
Therefore I cannot change the port to COM 41 to flash the .TOT file.
I constantly tried installing drivers for the phone both 3.10 and 3.08 but still no recognition can anybody help?
Some more info about the phone:
it's the D801 variant but its on Wind (Canada) not T-mobile
it was previously Rooted
it did not have any recovery software installed
no roms had been flashed previously.

Try to restore your phone using the official LGMobile Support Tool. Just switch on normally the phone, plug it to your PC and wait for your kdz to be downloaded. Once it done, it should install the kdz by itself. Then factory reset your phone (if needed) as it should ask you some pin/password.
Hope it'll help you as it did for me!
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?
Hello
I'm new here, I've been modding my lg a few times, always when bricked, kdz or tot files were saving me.
But now I've got real problem.
I was changing ROM from Cyanogen 13 to Cloudy 3.3. I thought I just need to flash rom via recovery (2.8.7.3 bump blastagator). Flashed fine, without any troubles, but when it came to reboot, phone just got stuck on LGs logo.
I knew i f*ed up.
Recovery isn't working, but Download Mode is turning on normally, at least it seems to.
So i tried to flash KDZ, but LG Flash Tool immedently shuts down giving "lg user...." error (don't remember what exacly it was saying).
Then i tried via tot files. But after installing drivers from tutorials, device isn't showed as "LGE AndroidNet USB Serial Port", but as few positions like MTP device or usb serial port(but not in Com ports) and all are marked as devices without drivers. Flash tool for tot also didn't worked here, because it did't found device.
What can i do now? Please help me.
[Edit]
So now, using different drivers somehow Jelly Bean installed by tot method (device didn't appeared as tutorial said, but it worked) phone is booting normally, but i can't again install lollipop with kdz files.
I was trying 3 different drivers, every giving instant error of flash tool.
What can I do now?
[EDIT2] LGUSERCSTool.exe is crashing. How can I install lollipop now?
Are there tot files for lollipop?
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.

Can i install any rom,recovery, with the help of stock recovery?
My device is not booting at all, it stock at galaxy s4 logo.
I can go to stock recovery & download mode
My pc & odin is not detecting my phone in download mode& recovery mode(I had changed about 10 data cables & 2 laptops windows 7,10 & all version of odin, I had tried installing every samsung drivers,kies, just every thing)
So plz help me out.
No, you can't.
And since your phone is not being detected, the only solution is to take it to a shop.
But if you can boot into odin or download mode then you have still a chance. Be sure you have a samsung driver to be able your computer and odin detect your phone
Is it possible the phone's USB port is damaged?
