STUCK at LG Logo, NO Download mode..Please HELP!!

hi all,
I have posted my G2 problem in another thread but was hoping more people can see it and help me...
PHONE Stuck at LG Logo after power up.
NO Download Mode,
here goes..
Believed I was conned... and this could be what happened to my LG G2 'D802':
my mobile is actually a D801 phone (motherboard) NOT D802 but loaded with D802 ROM
Phone was flashed (by me) with D802 ROM to remove error "Unfortunately, the process com.android.systemui has stopped" caused by corrupted Build.Prop system file during some editing.
touch screen error after new ROM was flashed (tried many diff roms), likely due to incompatible phone settings.
unable to flash D801 kdz since the phone was configured to 'D802', incorrect model detected while trying to flash.
managed to get a D801 TOT file that can resolved the incompatible model issue
Flash completed, phone rebooted..STUCKED at LG LOGO!
pressed Vol+ and USB cable, cannot enter download mode...stucked..
Factory reset using hardware keys, same problem..
please help ! any suggestion/s would be greatly appreciated!! thank you!!

use flashtool with another *dll

His download mode is not functional.
When in factory reset - connect to pc(does it throw errors or add a new device?)
If yes..then - read this
If no then still read it.

Just plug your cable to usb. Turn off phone and inmediately hold the button up and ull be in download mode.
Or If U have 801 rom try to root your phone and do recovery as 801 phone, after flash 802 rom !

Wait so what can you do? Hard reset? Download mode? Nothing?
Can you plug your phone and check that your phone is not detected in device manager?
All the drivers are installed?

[Q] Please help! Boot loop and recovery error!

Hi. I have a Verizon LG G2 VS980, which I rooted a few days ago. I had some trouble flashing TWRP and that has caused some issues now. When my phone is turned on, it just recycles the Verizon animation. When I try to do a hard reset, I get a "secure booting error" and then the phone turns off. When I go into download mode to possibly download firmware updates it just sits at 0%. I'm completely lost and can't seem to find any help that is unique to my problem. If you can help, please leave very detailed instructions. Thank you.

Follow this thread to flash stock firmware. Look for VS980 and do whats told.
And dont forget to change COM port to COM41 from device manager of pc. Its very important.
This thread is detailed enough. Still if u dont understand anything feel free to ask.

I did the KDZ method, but the LG Mobile Support Tool stops and says "lost connection to server". Then I click retry and it stops at 2% and says "Upgrade stopped due to an error". I've retried many times. Also, I made sure to download the KDZ file under Verizon. I don't understand.

Kdz should be fine.
LG Mobile Support Tool?? You should be using LG FLASH TOOL mentioned in the post.
Did u download all the files and drivers needed?
To enter Download Mode press and holding vol up key insert the usb cable.
If Normal flash doesnt work try CSE flash located at the bottom of the tool.

During the process, the LG Flash Tool opens up the LG Mobile Support Tool. Yes, I downloaded the verizon kdz file and both drivers. I followed the guide but no luck.

Strange problem!!
Try uninstalling LG Mobile Support Tool and try again every step very carefully.
If that also fails, hope u got warranty, so take it to service center and i think its the best option as of now.

The same thing was happening to mine! All I did to fix it was....
1. Make sure its turned off by holding the power button until the lg logo stops popping up
2. Hold down Power button+Volume down at the same time
3. Let go of both when you see the lg logo come up and quickly hold down on the power button again
4. From here a white screen will come up saying something like (to factory reset press the power button)
5. After you press it TWRP or Clockwork revovery will come up depending on what you installed
6. Recover your backup
I really hope this helped you!

Well bro I was stuck with the same issue..
This happens to me when i flashed a wrong twrp recovery for lg g2 d801 and it was stuck in critical error i was also unable to access download mode ..
But my Good luck was that i recovered it by doing silly thing ?
So i do following things. But make sure u know the corrert version of your lg g2 to flash kdz file with lg flash tool and also must have lg drivers intalled.
Steps to perform.
1. While in critical error screen you have an option to press volume up button to boot into download mode( although it will not boot to download mode) but still press volume up button so your Pc can detect your phone.
2. Now flash a kdz file of your lg g2 with flash tool. ( you can google for it to download flash file for your lg g2 and how to flash it with lg flass tool.)
3. When you will try to flash it will fail..
4. Now power off your phone by pressing power button.
5. Now boot to download mode and flash the correct kdz with lg flash tool and u r good to go..
To acess download mode power off your phone immediately press volume up button and while keep pressing it and plug in usb cable and you will be in download mode
I performed all this on lg g2 d801 but i hope u can try it on other varients as well. As i was scared of short circut method and srk tool didn't help..

[HELP] LG G2 D802 stuck on Fastboot

Hi All
I have LG G2 D802T (written on back of Phone) 32GB version. I want to install Android 5.0.2 as i was not getting Lollipop update so i installed Lollipop from here.
http://www.naldotech.com/flash-android-5-0-lollipop-kdz-image-lg-g2-d802/
I have followed all the steps very carefully and installation was completed successfully. Now the problem is it is stuck on LG Bootlogo and when i try to go into download mode, it takes me to Fastboot mode.
Can someone guide me in detail on how to recover my phone, which rom to install and how with links to ROM and Software, Drivers.
Would be be greatly appreciated.

Anyone?

I will reply to in this forum in a couple hours. One question. Does the pc detect your phone in fastboot at all??

Keep trying to get the phone into download mode. It took me alot of tries but i eventually got it. Then see if you can connect it to the lg support tool and run the update and it should get you back to stock android. If not, see the lg g2 unbrickable thread. Let me know how you make out.

Thank you very much for your efforts. Yes PC detects my phone in fastboot mode and i can also send commands through fastboot. BUT i didn't check if the phone can process on those commands or not.

Mode download doesn't work

Hello,
I want upgrade my LG G2 with a new rom 5.xX
This phone have only the operator update. No custom, no trwp, nothing...
I installed drivers and when i want access to download mode. I can't. I use the good proccess with vol up then plug usb cable always with vol up presses.
follow this procces after a little moment my phone show me battery logo charging.
So i can't access to download mode.
I would use this process
t was NOT bricked. I finally tried playing around with the LG Mobile Support Tool (B2CAppSetup.exe). Of course it detected that my phone already had the latest firmware from T-Mobile, but then I clicked Options>Upgrade Recovery.
It downloaded for a while then I noticed it had put my phone into download mode (it said "Rooted" in red letters at the bottom). Then it flashed the same firmware over and I immediately tested, it entered download mode right away. But I didn't end up needing that as Stumproot was able to brute force it now after the recovery flash.
Anyway, I couldn't find an answer anywhere else. Most results also have a bricked phone, but that wasn't my issue. This solved my problem and maybe it could work for others.
but it's impossible for me to install B2appsetup on my pc the installation begin then stop after 5s then nothing.
I have Win 10.
Do you have a solution for me , please??
