My LG G4 doesn't boot into download mode and LGUP doesn't recognize it. Whenever I power on my phone it boots to firmware update screen and it says: 633A B100 modified. The problem is that I can't do anything. I can't go into download mode or recovery.
This question is similar but I can't find the solution.

Hi.
My phone stopped responding today so I removed battery and turned it on again. But all I see is LG logo. When I choose hard reset it just goes back to LG logo and nothing happens.
I can go in download mode (download mode title on screen and nothing else, same as here: https://cdn-images.xda-developers.com/direct/2/8/1/4/2/5/7/image2.png) but my PC doesnt see my phone. So I cant try to fix via PC Suite or just flash stock rom again.
Phone is unrooted, stock 20f rom.
Please help me
My LG G3 is in a bootloop. I can use the hardware keys to go to download mode but afterwards there is no firmware update screen for mi to flash a TOT o KDZ file. I have searched the forum but cannot find a fix for my problem.
Please describe in more detail what happens

When i press to go tot he download mode, there is a download mode screen but afterwards no firmware update screen appears. If i charge the phone it appears to be a battery charging bootloop. everything i try fails and cannot recover my phone.
Hi Guys,
My LG G3 D855 32 GB cannot start after LG Logo. It doesn't go to download mode and recovery mode. I tried to downgrade to KitKat from Lolipop using the LG Flash tool + Tot File method. It failed in 16% and now i cannot go to download mode or recovery mode. It goes LG Logo and shuts down. I have swapped batteries, it doesn't even go to the firmware update page. I don't know whether it gor bricked. Please help me with a solution.
My LG G3 is and international D855 and is unable to enter recovery, with the phone going black after the twrp logo shows for a few seconds. The phone has no OS installed because I was going to flash a custom rom so there are only bootloops when booting up the phone. Entering download mode is not any good either because a message appears saying secure boot error and the phone goes black with only the LED flashing Red and Blue, I tried going back to stock with fastboot but in the process I lost the ability to enter fastboot, is there any hope
I'm hoping somebody can help and I would be extremely greatful, Cheers
If you can't access Download mode or fastboot mode.you have to do this as in thread.

I am using the LG G4 LG-F500S(Korean) which is stuck in bootloop after upgrading to Android 7.0 Nougat. I tried the flashing method with the .kdz file but I can't enter download mode.
Are there any solutions?
