What is the REAL way to enter download mode - One (M8) Q&A, Help & Troubleshooting

I'm trying to do this as a first step in rooting. One site says while phone is off power+volume down, another site says volume down, and another go to "fastboot" options under "battery" in settings 1st which doesn't even exist and no methods have worked so far. One source says do it while the phone is on! Wtf? So what single simple way is this done. It can't be this hard. Is it?

Download mode is for Samsung device only and there's is a guide to root m8 if u searched

I searched, that's how I came up with the 10 different solutions that didn't work but never mind, I found the "fast boot" option under "power" in settings. And for my phone at least it's volume down and power. Whatever. They need to make it once then stop touching it and playing around with ups and downs. But let's all go back to smiling and dancing.... until I stumble again on my way to rooting..

And how many buttons have succumbed to the pressure of the eager frustrated hands of the many users trying to figure out how long and tight to hold which buttons in what combination to get to"download" or whatever mode? I bet quite a few. I think a new method of getting under the hood is needed. Just like a car, a button and latch at most. Okay thank you. Good night.

Before you mess around i suggest to read up on terms and issues you might stumble on ! Learn adb/fastboot commands to the bone and then start all the rooting stuff.
Phone on :
Hold power + volume up, when the screen turns black (the reboot) you switch from volume up to volume down and keep the power button pressed all the time in this process. Release the buttons when you entered the bootloader.
Phone on and fastboot enabled :
Open a fastboot terminal on the pc and type :
Adb reboot bootloader
That should get you started.
Cheers.

Whoah there! I do:
Ensure the lights are on in the room.
Hold volume down and power.
After it reboots, let go of power.
In bootloader, let go of volume down.

For the step I highlighted in red, you mean power + vol up (forced reboot).
Power + vol down while phone is on takes a screen shot.

It can be done with the phone on (reboot the phone) or off (truly off, not with "Fastboot" selected in Settings, where the phone is not truly shut off).
If you do it from a reboot (either forced, or just selected reboot after holding down the power button) you don't even have to deselect "Fastboot" in Settings (only required if trying to do it from a powered-off condition).

If you searched specifically for the M8 methods to get into bootloader, they all should work. Either its just pilot error in doing the steps properly, or you are looking at instructions for other devices (which is suspected, since you reference "download mode" which is Samsung-specific).

can't believe you said that. I was trying to avoid that acronym abd as any sentence or two I've ever read on it sounded scary. but I'm tired of being a newbie on this stuff every time I want to root my phone, which is every time I get a new one, which on average is every couple yrs or so I forget what I did plus there are various methods.... okay, I'll spend some time on abd. any suggestions on all the different sources you find on rooting this phone? is there a main one in here or what about that fire thing I read about? some program someone wrote to unlock root and turn s-off, which I'm not sure I even need. now I just think I want to root it just so I can at least maneuver the data on my sd card then maybe install a rom or two. thanks!

Oh, and for my phone at least you just hold power and volume (up or down whatever I said I already forgot) while phone is about to power up, til it like drops then release the volume button only, fastboot screen comes up, then for the recovery screen steps from the red triangle, mind you this one took a bit of a struggle to figure out, simply hold both vol buttons, then power, then release JUST power. This all was definitely made to be idiot proof as I had to literally graduate to a step above an idiot to figure that out.

No, I mean vol down. It doesn't take a screenshot for me. In fact, if I just hold power, it says it's going to reboot, no volume needed.

Mr. Hofs,
Thank you so much. I was finally able to fix my HTC M8 with your method advice only. I have been googling a lot of other solutions that worked for other people but they never mentioned to hold the power button the whole time and just switch the volume up button to volume down at the right moment. Hats off to you sir!

lmfao relax. Hold your volume button down, hold the end key down(the button you hang up the phone with) then push the power button.
When your phone boot you should see a gray screen that say serial, plug your device into the computer and serial should change into usb. Then run the rom and there u go

Doesn't that trigger Ramdump mode (well, I don't know what that means, actually)?
All the OP needs is to go to Bootloader Mode to flash a ROM via USB. Bootloader is easily accessed by: Turn off phone, then press/hold Volume Down + Power button.

Sortof. I just tried task29 for the first time a few days ago. I freaked out when I got in the same situation as him, but then read through the thread. There's the option of shutting the phone off, and pressing vol down + power key. I ended up doing vol down + power key + push reset with stylus at the startup screen. Simplest solution for me.
taking off the battery, istnt that simplest?

In the very first posting of the Task29 thread, it says :
When phone boots to "Touch Pro 2" screen (or whatever your splash screen happens to be), I hold down the volume down button while hitting the reset button.

IMO, the smartest thing to do is when Task29 is near 100% (I think it pauses at around 96%), hold down the Volume Down button. That way, when the phone (tries to) reboots, it goes straight to Bootloader.
thanks all you have been more than helpful, ive been using this site for a while (for my android device) but just recently made an account. All of you keep on getting it done!!!

Hey, I have a Touch Pro2 and I tried the key combination above and it didn't work for me. I did get it to work however using the send key (green button) instead of the end key....
I.e, held volume down button, held send key and pressed power key once... ;-)
Phone MUST be off before doing the key combo...

Maybe using ADB or any tricks connecting USB?

Sorry nevermind, I took the device apart and push a metal screwdriver on the pwr button. It worked
power off
if your devices has root acces, install rom manager or something like it, you have inside it the option to reboot either in recovery or fastboot. if i remember ,in fastboot is an option, to power off
---------- Post added at 12:41 AM ---------- Previous post was at 12:10 AM ----------
a small correction, Rom Toolbox apk has the option to reboot in fastboot, but since you got an issue with the power buuton, i don t think you can activate the power down option, only to select it with volume keys

Help Can't access Bootloader

Hi All,
I have an international HTC ONE M8 which I managed to root and s-off without a problem. However since I s-off-ed the phone will not reboot into bootloader.
When I try to power off and reboot with vol-down and power it either reboots or flashes between the battery screen and TWRP, which say swipe to unlock but it flashes too quick for mee to do this. This a strange error I never come across before in the years Ive been flashing and modding devices.
Also ADB no longer sees this phone in fastboot, I can issue fastboot commands but not ADB
Can anyone help

You might also try making sure Fastboot in the power menu is off. And ADB won't work in Fastboot mode - you either have to boot into recovery or android for ADB.

Something happened to my M8 so I can't access bootloader anymore. Pressing Power and Vol Up just boots the phone and then the screen goes blank. Pressing Vol Down to get into fastboot doesn't work anymore (it used to up until now). Any clue?

Press and hold the volume down, then at the same time press and hold the power button (both should be held now).
Wait for the screen to go blank.
When the screen goes blank, release the power button, but continue to hold the volume down button.
You should then eventually see the fastboot/hboot menu.
OK, found what the issue was. The problem was that my phone's screen was going blank after the normal boot screen, so I couldn't see when it gets turned off. I was simply pressing the Vol Up + Power for too long, so it would go into full reboot. I just measured the amount of time it was taking to do this (was ~12 seconds). So I pressed Vol Up + Power for ~10 secs, then released those and pressed Vol Down. That finally brought me into Fastboot.
I could have probably gotten the same result by pressing Vol Down + Power, however, the phone screen was blank all the time, so it was difficult to understand when I should have released the Power button to let it go into Fastboot.

The red triangle screen is stock recovery. Power + vol up when on the stock recovery, will bring up the recovery menu.
Not sure what you are trying to do. Based on the subject of this thread you decided to post in, are you trying to get into bootloader? Or just trying to get the phone to boot to OS?
If you are trying to get into OS. You can try to wipe cache, and reboot to see if you can reboot back into OS (or factory reset and reboot, if you don't mind losing your personal data). But depending on what is wrong with the phone, you may need to do more to get into OS.

Everytime I do this, hold POWER, then VOL UP till screen goes black, release BOTH, then press POWER and VOL DOWN, then release POWER first time screen flashes, while still holding VOL DOWN, it returns to the OS every time!
Everytime I do this, hold POWER, then VOL UP till screen goes black, release BOTH, then press POWER and VOL DOWN, then release POWER first time screen flashes, while still holding VOL DOWN and then press POWER again, the screen CYCLES between BLACK and the RASTER glow on the LCD. About 3-4 secs of BLACK, then RASTER glow, then repeat. If I let go of POWER, it goes right to the OS again, every time.
Everytime I do this, hold POWER, then VOL UP till screen goes black, release BOTH, then press POWER and VOL DOWN, wait for RASTER glow and continue to press BOTH until first time goes BLACK, then release POWER while still holding VOL DOWN, it goes right to the OS again, every time.
I don't know what I'm doing wrong. I followed the HTC directions at the DEV site, to change the boot speed, but it wasn't in the BATTERY menu, it was in ACCESSIBILITY and called QUICK BOOT. For units with Android 4.2.x and up, HTC site said to turn on OEM unlocking in Developers menu, but this is 4.4.2 and there is no option in there to do that.
This is a DUAL SIM phone, so I assume that is an international version, also.
Further, when I do try the HTC site method of entering the bootloader menu, (press Volume Down and while pressing Volume Down, press Power holding both buttons to start the device into Bootloader mode (now Download mode for One M9 and newer devices) I get a menu

, but I don't read Chinese/Korean, or whatever language these characters are from, but it works like a TEST or SERVICE menu, as it puts the phone thru all the self-tests of its' various hardware functions. Not much help to me.
This phone has a crashed Android update that never completes every time it starts, but I can't tell what version or from whom. It does not APPEAR to be locked to any carrier as there are no logos on the phone or in the bootup screens. If I can every get it where I can flash it, then I hope to learn WHAT there is to flash it with.
Right now, I just want to get to the bootloader, so I can see if it will talk with the laptop using the apps I downloaded from HTC; Android studio, Java and the Sync Manager. Once all those hurdles have been jumped, if it succeeds and functions properly, and flashing rids it of the nasty malware, xrated crap its' infested with, I'll order a glass to repair it make it my own for a while.
Any help figuring out why I can't make the VERY CLEAR instructions I found in this thread work for me, will be very, very, VERY much appreciated.
Thanks to you all.
There is no "then press POWER and VOL DOWN" in the instruction, after release both power & volume up, press only volume down button.
What device is that ? Definitely not M8 & not M8 dual SIM.
If you still can boot, enable usb debugging in Developer options then run adb devices to see the serial no.
If it come out as weird as 123456789abcdef then it's fake htc.

I was very frustrated by the directions I got from HTC inserted below:
press Volume Down and while pressing Volume Down, press Power holding both buttons to start the device into Bootloader mode (now Download mode for One M9 and newer devices). If you have difficulty, power up normally, go to Settings->Battery and deselect Fast boot. Power down and try again.

Needless to say, but I already told how I got this. I don't mean to sound like a smartass, but I can't help it. I flashed and modded my first Motorola Droid back in 2012. This ain't my first rodeo, its' just that this phone has been one of the more frustrating broncs I've tried to break lately. If this is a "FAKE" HTC phone, I would not be surprised to learn that. I had not been aware until now that there are fakes.

Yep. Now, what do you recommend? WAIT!
I want you to know that I followed the link to your GUIDE. Very Well done, sir.
I found it remarkably well organized, detail specificity very professionally presented, and written for a layperson without sacrificing the value of educating them with vernacular of the high level technician. I commend you.
With that said, whether ir is while I have the OS up, or from recovery menu ADB function, this is what I get when trying to use ADB on this potentially worthless waste of time:
C:\Program Files (x86)\Minimal ADB and Fastboot>adb start-server
adb server version (31) doesn't match this client (35); killing...
error: protocol fault (couldn't read status): Connection reset by peer
error: could not install *smartsocket* listener: cannot bind to 127.0.0.1:5037: Only one usage of each socket address (protocol/network address/port) is normally permitted. (10048)

AND
C:\Program Files (x86)\Minimal ADB and Fastboot>flashing get_unlock_ability
adb server version (31) doesn't match this client (35); killing...
* daemon started successfully *

So, with all that, what say you to my question, "Now what?"
My Opinion, if it is a fake, disassemble it to explore the guts,
like a 1st year med-student exploring human anatomy on a
homeless, unidentified cadaver from the Morgue.

Same issue as who? The OP has an issue with the button combo making the phone reboot or flash between battery charge screen and TWRP. Plus, that post is from 2014, so their firmware most likely does not match what you have, even remotely. Another person who posted to this thread. has a dual SIM Chinese version. I doubt either accurately describes your situation.
Do yourself a favor, and don't post "I have the same issue" while giving zero details on your M8 version (CID, MID) whether it is modded (unlocked bootloader, custom recovery, root, s-off, etc.) as well as the current condition: is the phone powered off when you try the button combo, or stuck on a boot screen, etc.
Giving as many details about your device and situation makes it easier for us to help you.
The button combo power+ vol down will only boot to bootloader if the phone is powered down. And you may have to hold the buttons for a minute or more, depending on the current condition of the phone. If this doesn't work, of the phone is in another state (such as stock on boot screen with HTC logo) tell us of this, and we will advise you further.

Is there any alternative way to access to bootloader.

Does your phone boot into Android OS, or not? If so, I believe there are some market apps you can install to boot to bootloader, that you can try. Or you can do adb reboot bootloader.

No stuck on HTC logo.

Tried flashing Viper and now can't get to fastboot menu!

I tried flashing ViperOneM8 1.8.0 (ViperOneM8 1.7.1 -> 1.8.0) which I guess was the wrong thing (I think that was an update, should have started with 1.7.1 first). Anyway... Now my M8 boots to some type of android base OS without a lot of things...
1) It's not possible to get to settings as there is no settings app in the app drawer.
2) There is no title bar/task bar at the top. The area that holds the time, and a few icons at the top is gone.
3) There is no background.
4) There is no way to get on the WiFi do to #1 and because of this I can not add my google account. That in turn means no google play store access.
But the BIGGEST thing of all... I CAN NOT BOOT TO FASTBOOT!!!
- Power the device off.
- Hold the volume down button (also tried the volume up button) + press power usually boots strait to fastboot mode.
I THINK it has something to do with the fact that by default in the settings I need to untick the fastboot option in the dev options.. Well I can't get to settings. Now what?

Shut down phone.
Turn it on
Hold volume up+power button until it restarts
As soon as you get the black screen for restart release power button and hold volume down.
If your timing is right you will enter bootloader.
I tried it and it definitely works
Flash your nandroid or any rom you know was ok to begin with and you are up and running!!!

Tried that...
1) Powered off device.
2) Held power button for about 2 seconds until it came on then let go.
3) IMMEDIATELY I pressed and held down the power and volume up buttons.
4) The phone continues to boot up a little bit longer and gets to the verizon check (verizon splash screen) then shortly after goes black (as expected).
5) IMMEDIATELY let go of power button continuing to hold volume up button.
... .. .. .
6) I get the white screen that says HTC (powered by android)... NOT a bootloader screen as expected.
Update... When I try to click on the app drawer then top right click the little three dots, I try and "Manage Apps" ... ERROR "App isn't installed"...
:/

If you connect the phone to the computer, can you get fastboot or adb to recognize the phone?
If so, you can try adb reboot bootloader command or fastboot reboot bootloader comand

After 4 you release power button and press volume DOWN.
This will get you to the bootloader

Yea, I ended up doing the following...
1) While device is powered on, Press and hold Volume Up + Power until device reboots.
2) When it starts to reboot continue holding the Power button and change to the Volume Down.
That worked for me.

How to Get out of Download Mode

EDIT 2:
I swear I have no luck sometimes. What should be a simple unlock I now get this...
I put in the key per HTC Dev and went to flash the unlock_code.bin file and I get this on the PC and this on the device...now what? Just look at the two photos. What do I do here? Phone isn't responsive to anything on the physical device. The 3/3 becomes 4/4 if I try and send it again.
I tried fastboot oem boot (command error) and adb reboot (I get error device not found)
So I just went into download mode (long press power and volume down). It loaded up fine. I hit the power button to select view system info and the screen went black. Phone is a paperweight right now. Phone is 100% stock nothing done to it yet. USA 1.21. If I long press power and volume down again I just get the back & recent buttons to flash until I release the buttons.
Tell me it's something stupid I'm missing.
EDIT: Well I let the phone sit for 10 minutes or so it seems to want to power back on. WTF?

On mine, I held power and volume down or up (don't remember) for like 30 seconds plus, and it finally fired back up.
If you did it to run something in fastboot, try "fastboot reboot"

no I wasn't trying anything wasn't even plugged into a computer. I was just testing out to see how to get into that mode (figured universally it was PWR+VOL DN) but then I got the black screen of death.

Usually holding down both volume buttons for 10 second plus does the job if you are still having problems.

You likely entered the info mode which is a black display. Fastboot does respond in this mode so the aforementioned fastboot reboot-boot loader etc does work.

so for the future, how would you get out of that. I'm fairly certain that's what i picked. Say if I wasn't plugged into a PC
Probably volume up and power long enough to reboot it.

Well I panicked and then figured it out.
fastboot reboot
reboot phone back to download mode...reacquired the token key with a different generated key (weird?) and then it unlocked. Phones are weird sometimes...
