Alrighty, so I dropped my phone in water 2 weeks ago, immediately took out the battery, riced it for 2 1/2 days, and used it. It was working perfectly except for the volume rocker was working only for pressing it down. Now today, I wake up, go to school, and while walking my screen won't go on, it'll just act like the backlight is on but the led for the buttons on the bottom will come up. I pulled the battery, then restarted it, screen worked, but once I locked the screen, the screen stayed black. I get home, plug it in, and put into cmd "adb devices" and it pops up. So I try "adb reboot recovery" to just wipe and reflash hoping that'd fix stuff, but it hangs on "adb reboot recovery". The CMD doesn't move an inch, and I am not put into recovery. I am S-OFF via Revolutionary, and no HTC Dev unlock crap. If anyone could help me, I'd love you. I'm due for an upgrade with Verizon June 2014 and can not be without my phone due to business reasons. Also, any suggestions on phones to get when I get my upgrade? :good:

When I do that it basically is saying that fastboot isn't there. I typed just adb fastboot and it did nothing. I did adb fastboot reboot recovery and still nothing..
*EDIT*
I ran fastboot reboot-bootloader so I could get into recovery like that and it hangs on "< Waiting for device >"

When I power and vol down, it turns onto the HTC screen, then it turns off. Then once I let go of the keys it just regularly attempts to boot it.
I honestly wish I knew what was wrong with my phone. I've been missing phone calls and whatnot due to this error. I hope this can be fixed!

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

Press and hold power and volume up until phone shuts off. Let go of power and volume up then hold volume down until bootloader comes up -_-

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.

Thanks for this post! I've spent a total of 5+ hours trying to get into the bootloader so I could restore a backup after a bad flash soft bricked me.

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.

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.

Great question!! Unfortunately, the answer may be the solution to at least most of the problem. The next question would be "What implications does that present? Does that make it irreparable and essentially worthless?"

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)
could not read ok from ADB Server
* failed to start daemon *

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 *
error: no devices/emulators found
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.

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.
My HTC One M8 (Verizon) is seemingly bricked. My phone is rooted, S-Off, with the stock ROM. I have been trying to update to the latest OTA update by returning to stock. I had previously modified some entries in the Build.prop and Platform.xml. I knew those had to be default in order for the OTA to work. I had copied the original files and pasted them to my SD Card so that I could simply cut the modified versions, paste them to my SD Card, and cut the originals from my SD Card and put them in their corresponding system folders.
Upon a reboot something apparently went horribly wrong because all my phone does now is boot with the white screen and green HTC Logo, then the screen goes black. I have tried the typical Power Button + Volume Down but it won't enter the boot loader. The good news is that the USB port seems to still work for my windows computer recognizes a device connecting to it but it doesn't show up as an interactive device in windows explorer..if that makes sense.
Please Help!

When you connect it to the PC can you pick up the device with adb? If so, have you tried to run the command from adb to boot it into bootloader? adb devices ... if found, adb reboot bootloader

I'm not too familiar with ADB commands but I typed in "adb reboot recovery" and it said: "error: device not found" so even if my command was wrong it's still not detecting it. I also tried: "fastboot reboot bootloader" and it just says "waiting for device"
Also I feel like it's worth mentioning the phone is automatically rebooting every two minutes or so (haven't timed it exactly but it's a while). Still showing the green HTC Logo then the screen goes dim, then the screen turns off.

Try holding volume UP + Power button, this simulates a "battery pull", just hold it in for a while it can take a while to "pull", when it's off try again booting into bootloader, volume DOWN + Power button.

I held Volume Up + Power Button and it showed the white screen with the green HTC logo. I then released all buttons. Once the screen turned off I then held Volume Down + Power Button for two minutes straight and nothing happened.
Even though we haven't found a solution yet, I am appreciative of the help.
sounds like you never installed the htc drivers for your phone, hence your pc doesn't see the phone when you are doing ADB commands.
install the drivers for it, then try the ADB commands via your pc
and dont mess with the build prop or other system files unless you have a working back up and are 101% certain about what you are doing..
Just remember to change directory in command prompt to the folder where adb.exe is located.
I don't know why the device doesn't reboot into bootloader though when you hold volume down + power button, shouldn't have to hold it for 2minutes. Holding volume up + power button to simulate a "pull" should only take up to 20 seconds or so at most and pressing volume down + power will then immediately take you into bootloader mode, or at least it's supposed to.
Did you release the volume up / power combo when the screen went dead or before? Try holding it until the phone shuts off and then right away press volume down + power.
Sorry if I'm not answering right away though, busy eating, and will be here and away for the next hour or so while I get ready for work =o( once I leave for work I'll only be able to help some more after like 2 hours or so. Hopefully we can do something before then though =o)

You're right, I didn't install the drivers. I did so and ADB was able to recognize it and I was able to access the bootloader. Thank you everyone for your help. I won't be making the mistake again.

So you'll be able to fix it from here on then? I was just about to link this thread to you as well should you have gotten adb to work again, it's for the RUU for Verizon seeing as you said you're on Verizon.
But going by your response up there you might already know how to fix this issue further :good:

Share another method of getting into recovery mode on non-responsive blank screen
Hi,
I just want to share how I accessed recovery mode with the same build.prop issue but with S-ON (might work with S-Off too).
I found the solution from here:
http://forum.xda-developers.com/htc...ter-download-mode-t2853100/page2#post62490577
To get into recovery mode on a non-responsive blank screen, hold the power button and volume up button at the same time and then approximately after 10 seconds, switch from pressing the volume up to volume down button before the HTC logo white screen shows while still holding down the power button. After, a white boot screen will give an option to go into recovery mode.
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.
Hey all,
Hope you've been keeping safe and well.
So I was flashing the new PixelExperience ROM - and seems like I made an error somewhere along the way.
I'm looking to return to stock, and then give the process another shot - but at the moment my phone is stuck in a bootloop.
The bootloader is unlocked - and the boot goes through the following screens before rebooting:
1. Samsung Logo
2. "The phone's bootloader in unlocked....Press power key to continue"
3. Samsung Note 10+ Logo Screen.
I'm trying my best to try and boot into either download or recovery mode, but to no avail - it just restarts the bootloop on each combination I've tried.
Any solutions on how to get moving with this?
Thanks!

Timing will be the key. To help out, boot up as you have been, but as early into the boot cycle press and hold the Vol - and power button for up to 5 seconds (until phone manually shuts off) [it will actually reboot the phone])), then the instant it powers off and begins to power back on (try a few times to get used to the timing) press and hold the key combination for recovery or download mode. In my experience whatever combination you go with while booting, the power button only needs to be held for the first 5 seconds or so of the combo button press/hold.
The other button, Vol+ or Vol- should constantly be held until desired mode begins to load.

Thanks for your quick and detailed reply man, appreciate it.
Still trying, new cords, ports, the whole buffet. Will keep at it.
Major flag though - my PC doesn't recognise the phone anymore, checked the USB ports in Device Management and nothing comes up. I've tried different cords and ports to no avail.
I have a feeling that because the device doesn't think it's not plugged in - it doesn't boot into recovery.
Just another detail - the flash goes on just before the reboot. Does this signify anything?

I'm not familiar with any significance the flash may point to. You've probably already done this.....but be sure to reboot PC....
Have you tried booting to recovery yet?
