Skip the reinsert battery part in your item #1:
1) Remove battery
2) Hold Volume plus and minus keys down
3) Insert USB cable while still continuing to hold down those two buttons.
WIthin 1-2 seconds you should have download mode. When download mode appears, then re-insert battery. For sure you're not going into charging mode with no battery to charge. This is the method I always use, and it always works (aside from hard-brick situations, but you can access battery charging mode/graphics, which surely means that ain't you).
not works.

What does your computer say when you plug it in? If in Windows check Device Manager and see what your phone is being recognized as. Can you access the phone's contents via USB cable from your computer? Does ADB recognize it at all? Or does it just loop like that, not starting?
Also, it sometimes takes several tries to get it into download mode, as if you're holding the buttons down and not timed just right, the phone ignore your attempt. Make sure you do not let go of both volume buttons even after you plug in the USB cable, you must continue to hold them down for a couple of seconds (until the DL mode appears). Don't even think about putting the battery back in until you see that download mode box. Try that a few times maybe? If it doesn';t work ,maybe you're boned.

remove battery and place it again. then press both volume+ and Volume - . By keeping pressed both buttons insert your usb cable. don't release pressed buttons until its in download mood. by the way install unified adb driver for android by koush if your using windows 8.1 otherwise lg official driver is ok

Im able to get into twrp recovery, and fastboot mode but not download mode... I wanted to put the phone back into stock and i thought wiping out everything would do so but i guess not.
Whenever i press the download mode command which i did was volume up down and power then plug into the laptop the 3 buttons will flash but my laptop won recognized it. I tried installing the LG Optimus G drivers but still unable to install it. Also TWRP says that the phone isnt rooted anymore and has no OS.

First off it's Vol Up + Vol Down while powered off and then plug into computer. DO NOT press the power button.
Secondly what ver. of windows and did the computer have any issues prior with connecting to the phone?
There is another fix but it's a bit drastic and wouldn't recommend it at this point.

oh well that might be the reason why. il try it out..im using windows 7 and it was working before i wiped everything.
link me to that fix if anything thanks
On my phone, Download Mode is only accessed when Vol + and - and power from a powered off state, while any USB cord is plugged in, either to a PC, or a wall charger.
After flashing, i noticed that the phone has some issues powering on and off normally i.e. phone completely died, plug the phone into the charger, screen turns on, phone is theoretically charging, but does not show any charging display icon. Which then forces me to unplug the phone, press and hold the power button for 10 seconds, press and hold the power again to turn the phone on, and immediately plug it into the charger in order to get the phone to normally boot up. I flashed CM 10.2 from the original android dev thread. I think that was just a design flaw that LG had originally, but meh, what can i say.

Hi, as the title says I am completely unable to boot to download mode on my E988. I have literally tried every possible combination of button pressing but nothing works. I have tried rebooting to bootloader from cwm but that doesnt work either, all it does is reboot, show the LG logo, then it reboots normally.. I have tried using terminal emulator to use the command "reboot download" but it doesnt work either, all it does is reboot, show the LG logo, then it reboots normally again. It seems that I am completely unable to access it at all. Any ideas?
Have you try with one end of the usb cord already plug in either your computer or phone, hold down both volume buttons, and plug in the other end. This was the only way down load mode would came on for me until I fixed the phone.
Yup I have. No combination of keys and button pressing seems to work for me it's odd.
Sent from my LG-E988 using XDA Free mobile app
To add on to my previous post, when I do the method whereby I hold vol + and vol - and plugging the usb cord in without my phone's battery, a message shows up when it is detected saying that a "...usb device has malfunctioned...". My phone will then just keep showing the lg logo over and over again causing the message to pop up again and again as the phone is detected and then not detected and the cycle just repeats itself. I have tried to reinstall lg drivers but nothing seems to work...
Edit: It would seem that the phone is indeed trying to boot to download mode whether I use the key combination or command, but it is unsuccessful in doing so and just reboots. Has anyone ever encountered this problem?

Hi,
I installed CloudyG3 rom today and phone is not starting nor going into download mode.
I have LG Optimus G Pro E980 AT&T
I want to be sure that v10k is a factory image ?
AT&T E980AT V10k
And how to go into download mode because I tried many times and still black screen.
Regards.
Take the battery off, then hold both volume and power buttons together simultaneously, now plug the USB cord into your device, then connect the other end to the computer. The download screen may come on. Once the download mode comes on, put the battery back in and proceed as before. If this method doesn't work for you, try other combination such as holding both vol + pow buttons with the cord already plug into both phone and computer. Keep trying and you will get to it eventually.

Hi there. After (an attempt) to unlock the bootloader of my A50 and installing TWRP Recovery (TWRP_A50_Magisk_Prepatched) i find myself in an orange bootstate. I can't get it into recovery, download or fastboot mode. It seems like a full brick. I can't even power off the device. Only Volume up, Volume down and Power button let's the device reboot but then the same boot problems appear. Is there anything i can do to recover my phone?
Text of first screen when booting up:

Try connecting your phone to your PC with the USB Type C cable, and do VolDown + Power to reboot the phone, and the moment the screen turns black, press VolUp + VolDown. It'll bring you to a different screen where you can press VolUp to go into download mode for flashing the stock firmware via Odin. I got my stock firmware from https://samfrew.com/all/page/2/#t (you'll need to search for your Model Number - SM-A505F/SM-A505FN/SM-A505FM, and select the correct Region. Also, select the correct Modem Version (the last 4 letters/number of the item to download). Then, follow the "Flashing Guide" at the bottom of the Samfrew page where you downloaded your firmware.

You can find answers in the S10 forum. But I think the steps will be the same (this is A8 device/forum).

I HAD the same issue an I resolved it.
There are 2 methods to overcome this problem.
I even wrote a PDF and attached here in this post.
Below is SOME content from the PDF so it could be easy for users to find it on Google. I still strongly recommend you to refer to the PDF attached as it has pictures as well.
Samsung Galaxy M31 / Samsung M31 Screen is stuck on the following error message / error screen:
‘This phone’s bootloader is unlocked and the software integrity can’t be verified. Any data on this phone may be vulnerable to attackers. Don’t store any important or sensitive information on the phone.’
‘The phone is not running Samsung’s official software. You may have problems with features or security. And you won’t be able to install software updates.’ (error screen looks like below):
I was using correct TWRP and I was on Android 11 One UI 3.1.
Just to experiment, I flashed wrong TWRP version which was meant for Android 10 while being on Android 11. And so this problem started. Stuck on the error screen. Phone will not power off or on. Could not even enter the bootloader screen. Nothing works whatever keys I press. The same screen comes up. When the phone goes off and the phone will not accept charging that mean even you it whole night connected to charger, phone will not be charged- the same error screen.
So, the battery was not charging (my battery was at 24% just before this tragedy happened. It was late night and I thought of waking up tomorrow and plug in charger for an hour thinking if its battery is quite charged then I will follow Fix Method 2).
I woke up next morning and the phone was off (Battery drained fully). To this I was happy thinking that I can now hold Volume + and Power key and connect USB cable to enter Bootloader. When I did that phone would enter bootloader and gets switched off automatically (remember the battery was drained completely, charger too failed to charge battery and phone is not drawing enough power from USB port to stay on bootloader. On bootloader screen the phone’s display is fully on so more power usage).
Now I knew that the USB port is not proving enough power so that the phone could remain On while in bootloader when I hold Volume + and Power key and connect USB cable to enter Bootloader. I know for sure that Fix Method 2 will fix this for sure but it’s quite tiring.
So I referred to my PC manual to figure out which USB port provides maximum power. I found the right port (refer pic below):
So now I figured out 5 Volts port and plugged the original white Samsung M31 USB cable into one (refer the pic below):
If you don’t know which USB Port is 5 Volts then I recommend you to try all the ports and try getting to bootloader screen.
So when the phone was off, I pressed and hold the Volume up and Volume down key and with other hand I connected USB cable and now the phone went in bootloader and then I quickly flashed the right TWRP. Disconnected the USB cable and put the phone to charge and now it was accepting charge. Phone was back into life.
So I resolved it by Fix Method 1 below:
Fix Method 1: On my PC, I located the 5 Volts USB port and plugged the original white Samsung M31 USB cable into one (refer the pic below):
Entered Bootloader screen.
How to enter bootloader screen:
Assuming your phone is unlocked and the developers options are on and you have enabled USB debugging in Developer options and you have little knowledge of flashing firmware or TWRP via Odin.
Press and hold Volume Up and Volume down keys together with one hand and using other hand, connect USB cable to phone and release all the keys. Now phone will show bootloader screen which looks like below pic:
I quickly flashed the correct TWRP via Odin:
Flashing TWRP:
· Make sure OEM Unlock is ON in developer settings;
· Turn off the phone;
· Press the volume down + volume up button whilst the phone is connected to a pc to boot in download mode;;
· Long press vol up then confirm you want to unlock bootloader (this is needed one time only);
* Please be aware all your data will be erased including internal storage and phone will reboot!!
· Let the phone boot normally, pass the setup and connect to internet (wireless or mobile data) in order to unlock RMM;
· Make sure OEM Unlock is ON in developer settings;
· Turn off the phone;
· Use Vol up + Power + usb cable plugged to a pc to start the phone in download mode, short press vol up to confirm you want to go to download mode;
* If by any chance you see RMM state=Prenormal or KG state=Prenormal, factory reset data and redo from step 5!
TWRP screen was up. I tapped on Reboot and it did not reboot because the battery was not enough charged however I saw that TWRP Menu this means TWRP was working so the phone will boot up once it is charged.
Now I plugged in charger and was happy to see the correct charging screen (refer below pic):
I would turn power switch Off and On it quicky to know the charging percentage.
When it reached 20% I started phone (obviously by long pressing power key and it booted up just fine).
I loved myself
Fix Method 2:
Remove the phone’s back cover.
Be careful while removing the back case as you could screw the finger print sensor.
Disconnect the battery connector from motherboard and reconnect it.
Do not turn on the phone. As turning On will again get you back to the same error screen.
Put the back cover on.
Connect charger. Do not turn phone On yet. Wait for 5 min.
Do not even touch the phone.
Now you need to know the percentage of charge so do not hit the power button yet instead locate the main switch to which your charger is connected. Quickly turn Off and On and look at phone it shows charging percentage.
Once charging percentage reached around 20% you can touch your phone and power it on and it should boot up fine. It should not take more than 5 min to boot up.

So, the battery was not charging (my battery was at 24% just before this tragedy happened. It was late night and I thought of waking up tomorrow and plug in charger for an hour thinking if its battery is quite charged then I will follow Fix Method 2).
I woke up next morning and the phone was off (Battery drained fully). To this I was happy thinking that I can now hold Volume + and Power key and connect USB cable to enter Bootloader. When I did that phone would enter bootloader and gets switched off automatically (remember the battery was drained completely, charger too failed to charge battery and phone is not drawing enough power from USB port to stay on bootloader. On bootloader screen the phone’s display is fully on so more power usage).
Now I knew that the USB port is not proving enough power so that the phone could remain On while in bootloader when I hold Volume + and Power key and connect USB cable to enter Bootloader. I know for sure that Fix Method 2 will fix this for sure but it’s quite tiring.
So I referred to my PC manual to figure out which USB port provides maximum power. I found the right port (refer pic below):
So now I figured out 5 Volts port and plugged the original white Samsung M31 USB cable into one (refer the pic below):
If you don’t know which USB Port is 5 Volts then I recommend you to try all the ports and try getting to bootloader screen.
So when the phone was off, I pressed and hold the Volume up and Volume down key and with other hand I connected USB cable and now the phone went in bootloader and then I quickly flashed the right TWRP. Disconnected the USB cable and put the phone to charge and now it was accepting charge. Phone was back into life.
So I resolved it by Fix Method 1 below:
Fix Method 1: On my PC, I located the 5 Volts USB port and plugged the original white Samsung M31 USB cable into one (refer the pic below):
Entered Bootloader screen.
How to enter bootloader screen:
Assuming your phone is unlocked and the developers options are on and you have enabled USB debugging in Developer options and you have little knowledge of flashing firmware or TWRP via Odin.
Press and hold Volume Up and Volume down keys together with one hand and using other hand, connect USB cable to phone and release all the keys. Now phone will show bootloader screen which looks like below pic:
I quickly flashed the correct TWRP via Odin:
Flashing TWRP:
· Make sure OEM Unlock is ON in developer settings;
· Turn off the phone;
· Press the volume down + volume up button whilst the phone is connected to a pc to boot in download mode;;
· Long press vol up then confirm you want to unlock bootloader (this is needed one time only);
* Please be aware all your data will be erased including internal storage and phone will reboot!!
· Let the phone boot normally, pass the setup and connect to internet (wireless or mobile data) in order to unlock RMM;
· Make sure OEM Unlock is ON in developer settings;
· Turn off the phone;
· Use Vol up + Power + usb cable plugged to a pc to start the phone in download mode, short press vol up to confirm you want to go to download mode;
* If by any chance you see RMM state=Prenormal or KG state=Prenormal, factory reset data and redo from step 5!
TWRP screen was up. I tapped on Reboot and it did not reboot because the battery was not enough charged however I saw that TWRP Menu this means TWRP was working so the phone will boot up once it is charged.
Now I plugged in charger and was happy to see the correct charging screen (refer below pic):
I would turn power switch Off and On it quicky to know the charging percentage.
When it reached 20% I started phone (obviously by long pressing power key and it booted up just fine).
I loved myself
Fix Method 2:
Remove the phone’s back cover.
Be careful while removing the back case as you could screw the finger print sensor.
Disconnect the battery connector from motherboard and reconnect it.
Do not turn on the phone. As turning On will again get you back to the same error screen.
Put the back cover on.
Connect charger. Do not turn phone On yet. Wait for 5 min.
Do not even touch the phone.
Now you need to know the percentage of charge so do not hit the power button yet instead locate the main switch to which your charger is connected. Quickly turn Off and On and look at phone it shows charging percentage.
Once charging percentage reached around 20% you can touch your phone and power it on and it should boot up fine. It should not take more than 5 min to boot up.

I HAD the same issue an I resolved it.
There are 2 methods to overcome this problem.
I even wrote a PDF and attached here in this post.
Below is SOME content from the PDF so it could be easy for users to find it on Google. I still strongly recommend you to refer to the PDF attached as it has pictures as well.
Samsung Galaxy M31 / Samsung M31 Screen is stuck on the following error message / error screen:
‘This phone’s bootloader is unlocked and the software integrity can’t be verified. Any data on this phone may be vulnerable to attackers. Don’t store any important or sensitive information on the phone.’
‘The phone is not running Samsung’s official software. You may have problems with features or security. And you won’t be able to install software updates.’ (error screen looks like below):
I was using correct TWRP and I was on Android 11 One UI 3.1.
Just to experiment, I flashed wrong TWRP version which was meant for Android 10 while being on Android 11. And so this problem started. Stuck on the error screen. Phone will not power off or on. Could not even enter the bootloader screen. Nothing works whatever keys I press. The same screen comes up. When the phone goes off and the phone will not accept charging that mean even you it whole night connected to charger, phone will not be charged- the same error screen.

Hi, friend. I have the same problem. But I don't even have a bootloader. When I log in, I just get a black screen.
So I have spent hours now looking around for an answer the phone is find my phone locked and I can't remember my pin code. I have done all the tricks with the combination keys.
The usual way to get into Recovery mode is Hold V+ and power until the phone vibrates and you should be in recovery mode release the keys. (Doesn't work)
Iv read that you should have the USB cable connected from pc/laptop while you do the same holding V+ and power button... (doesn't work ether)
and download mode should be very easy just hold V+ and V- plug USB cable from pc/laptop and you should get into download mode by pressing V+. Will only show charging Icon and that's its.
So is it possible to turn off this modes from the manufactor? Or is this a completely new security future? How can you use odin? How can you wipe the cache? If you end up having some issues.
Im going nuts....
No way to get into fastboot ether. So if anyone know why this is happening to me or got any solution I would appreciate it.
Plug in your cable with the phone turned on. Hit Power Off and wait for the phone to fully turn off. The charging logo will show up so let the animation do its thing. After maybe 20 seconds, press Volume up + Power and keep them pressed until you boot to recovery. If the command wasn't recorded in the first place and the phone is still off after more than 15 seconds, let go of the buttons and press them again and keep them pressed until it boots in Recovery

It will not work. How the hell should I be able to cle3ar cache if I got a boot loop ??? They can't just turn off recovery mode mand download mode??? This is so strange even paying for a frp reset but not even he does know what wrong??? Can they turn off fastboot, recovery mode and Download mode on this new phones? Is it because its locked with find my phone? 1 week researching now. It will only vibrate. And my PC cant find my phone anymore worked fine 30min ago nothing has changed... So annoying never seen this happened before every combination with buttons to get in any mode doesn't work only vibrates and go to pin lock screen...
Take it to a Samsung Experience center at best buy. Or send it into Samsung for repair.
download mode:
Turn off phone
plug cable in pc but not in phone
pres "volume +" and "volume -" in the same time
plug cable in phone
recovery mode:
plug cable in pc and s22
power off
press "volume +" and power
wait until see recovery mode

thats a solid advice assuming his bootloader/recovery/download mode is fully functional then this advice works, in his case and in mine too it does not work and trying to get to the root of the problem is the key. In my case recovery mode gives error on screen so it may have to do with the way firmware is installed as these modes are not accessible.
have you sorted it out? Its nearly a year onwards =)

This, at index 2:48 minutes.
It needs to be connected to the PC. Another screwy quirk Samsung added recently. Your button timing/sequence matters as well.
On my N10+'s you can go into recovery directly with a restart if you do it right. Otherwise they will puke on you.
