Cant get into download mode,

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.

Freezes on fastboot when plugged in

So I'm trying to install the new Lollipop preview, but everytime I boot to fastboot and plug the device into my Mac it freezes. It's rooted and unlocked, does that make a difference? If I go to fastboot without being plugged in it functions as expected, letting me move up/down, but as soon as I plug it in it doesn't respond to anything and I have to hold power to force restart.
EDIT: Fixed. I think it was the cable. I used a different cable when I got home and it works fine now.

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

Just another person who has Hard Bricked his M8

Hello Everyone
TL;DR Screen doesn't come on at all, battery led only flashes while it is rebooting (More details below), and When plugged in to my windows pc, a bunch of "Local Disk Found" pop up, some of the volumes I can access, most I cannot.
I have searched and searched the internet the past 24 for solutions, and have yet to find one. So imma walk you through what led up to the issue, as well what solutions I have tried.
Yesterday while I was trying to update my rom, I ended up getting stuck in what I thought was a boot loop. I then decided to hard reset my phone and go into recovery in hope to try to reinstall the rom. To my surprise, I could not access the internal sd card in the phone. Data was unmounted in the "Mount" settings and I could not what so ever remount it. After this I tried to side load it, but to no avail.
In response to all my attempts to fix the phone at that point, in frustration, I just said "**** it" and went into factory reset in the bootloader. This is where the hard brick happened. At this point, the screen would not come one, and the battery led was not lit when plugged in. I tried letting my phone charge over night and then, tried the "Battery Recalibrate method". I then tried the "Hold Pwr + Volume up for 10 seconds, then Power + volume Down until you access the bootloader"
After that, I then thought that the firmware was corrupted, so I tried to see if I could push an img to the phone, however fastboot does not see the device. I tried RUU, it does not see the device. I tried the HTC Unbrick method by Dexter that required me to install ubuntu and do some things in terminal, that also did not find the device. And here I am stuck. One thing unique to my situation that I have yet seen reported in the countless threads I have searched, is that when I plug my phone to my pc, a large amount of disk drives are found. Most of them are not accessible, but there are a couple that I can go in and see files for. Windows asks me if I want to format the ones I can't access. When hooked to my pc, I tried the the Power + volume button combinations, the only thing that seems to happen off of this is that my phone seems to reboots, and the battery indicator briefly shows.
Anyways, this is all I can remember. Any help would be GREATLY appreciated. I don't really think it is a hardware related issue since my phone does somewhat boot. However it seems it can't get to a bootloader what so ever.

Try holding power and vol up for a long time, like a minute or more. Try with and without charger attached, and after sitting on charger overnight.
If the bootloader is intact, the phone is likely not truly bricked (recoverable). And I don't see how you could have damaged hboot by the actions you mentioned.
What is the phone's original CID (carrier version) and are you s-on or s-off?

Verizon is the carrier version, and I am s-off.

Held vol + up for 5 minutes both with and without the charger. One time with the charger into my computer, and another into the wall. When it was in my pc, I can tell its doing nothing but rebooting over and over by the notification sound, and the constant "Found new disk" notifications I got. However still no luck, no screen turns on, no sign of hboot. I'm hoping to have some luck after leaving it on charge overnight and trying again.

So still nothing after leaving it on charge overnight and I held vol + up for about 5 minutes. Things seem grim.

I think the proper thing to do when you discovered internal storage was not mountable, would have been to use the TWRP option to format internal storage (in Advanced Wipe options).
But now I'm baffled as to what happened that would have rendered the phone unable to boot into fastboot mode. Fastboot won't recognize the device if you can't boot into fastboot mode, which leaves use kinda stuck.
So you didn't try to flash anything during the course of all this troubleshooting?

What you did - "Hold Pwr + Volume up for 10 seconds, then Power + volume Down until you access the bootloader" is totally wrong
I used to get this bunch of local disk pop-up and this is how I get out the problem
Connect the device to pc, you can hear notification sound on pc that device is connected. Ignore all those bunch of local disk pop-up
Press & hold both power button & volume up button until you hear another notification sound that device is disconnected from PC (that's the indication that device is restarted)
Release both power & volume up button and quickly press & hold volume down button (only this one button)
This should get you on bootloader

No, nothing was flashed except the original Rom update that got this snowball rolling (Not saying its the roms fault, most likely mine).

This is the one combination I forgot to mention in the op, sorry for that.
But I have tried this, before and after your post, still no luck.
If it worth mentioning, I can just hold power + down and it still reboots over and over. As well as just power. As a matter of fact, all button combinations reboot the phone over and over.

I thought the screen was dead? If so, how do you know its rebooting?

By it constantly connecting and disconnecting from my pc. If that doesn't mean its rebooting, then I guess I'm mistaken.

Well, it might mean that.
If it in fact is rebooting over and over on its won, simply holding the vol down button for a long time, should put you into bootloader (on the next reboot "cycle"). Again, assuming it is in fact rebooting, and that bootloader is intact.

Question Why wont my S22 go into Download mode or recovery mode?

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.
