HOLD
Power, Vol Down and Home for 30 seconds
Power+vol down reboots, with home it boots to download mode. Always. If it doesn't, your battery is empty. Or you didn't press long enough?
It is not working with any combination.
I now put the Tab to another connector (from S2) into a different outlet's see what tonight.
Regards Klaus
Do not charge it! Just test it. Your other option would be to let it run completely empty. That does take 3 days in standby crash with display off. Then it will reboot for sure.

Concentrate on boot to download mode. It needs full 20 seconds. Very likely you just don't do this right. A hard brick would be extremely unlikely!

When you press power + vol up the DHD vibrates 3 times and the charge light flashes. I think it enters some sort of programming mode. From this mode the phone shows up in windows device manager as qualcom. Does anyone know what this is for? - just curious that it might be of some use

Hi,
I have a faulty power button, so is there any way to turn on the device without it?
Maybe using ADB or any tricks connecting USB?
Please help me! :/

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

1. Unplug phone - VERY important
2. power on phone, doesn't matter if it is boot looping or whatever
3. hold vol up and power EXACTLY 10 seconds
4. let go of both
5. hold vol down and power till boot loader comes up.
You have no charge because you are running an old ver of twrp, get 2.7.1.0

Share how I fixed my HTC M8 with the same problem.
Hi,
I just want to share how I fixed my HTC M8 with the same issue. The method is the same but a bit different. I found the solution from googling the below link:
http://forum.xda-developers.com/htc...ter-download-mode-t2853100/page2#post62490577
The essential method is to keep holding down the power button and don't let it go while pressing on the volume up button to reset. At the very moment before the phone resets and shows the HTC logo white screen, switch from pressing the volume up button to the volume down button while holding down the power button. Or you can count 10 seconds and switch before the screen resets.
I hope this helps other people with the same issue.

Thanks, the pwr + vol-up 10 seconds before the phone hard resets, them pwr + vol-down got me back into hboot and recovery and then out of a build.prop issue.
I have no idea why this is a thing: Getting into the boot loader is usually easy. I can't imagine why when the system doesn't boot normally that the standard procedure to enter hboot changes.
regardless of retarded engineering on qualcom or htc's part, thank you an0ther.
My Tab S 8.4 is still unrooted.
I tried going into download mode to just check the KNOX status.
Unfortunately you cant turn it off or pull the battery out!
Doesnt work when pressing Power + Vol UP + Menu or Power + Vol Down + Menu or just holding the Power.
Here's what i did. In Download Mode, Press and hold Power + Vol UP + Vol DOWN
It should restart the device successfuly.
I hope it helps.
On my 10.5, power + Vol Down is enough.
Thanks
Thanks - that had me puzzled for a bit!

Thank you so much
Definitely thought I'd made myself a paperweight

Absolutely correct. :good: All that is required is hold VOLUME DOWN + POWER nothing else until it restarts.

All you probably did there was as above as you had the VOLUME DOWN button pressed.The procedure can be used anytime the tab s is on. Its the equivelant of a battery pull.

Thank you....it worked...I was trying to root and this happened!!!
Thank you, My Samsung 8 Note was stuck in the "downloading" mode. Pressed the Vol + and - and power buttons at the same time for about 4 to 5 seconds and it reset to a screen showing 4 options . use the Vol - to # 4 "power off phone". After it powers down turned it on and it was back to normal.
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!
