LET ME MAKE THIS VERY CLEAR - MOST OF YOU ALREADY KNOW HOW TO ACCESS DOWNLOAD MODE OR RECOVERY VIA HARDWARE BUTTONS....
BUT NEWER PHONES SEEM TO HAVE HARDWARE ACCESS DISABLED.. THIS IS A WORKAROUND FOR THESE LOCKED OUT PHONES...
THERE IS NOW A ODIN FLASHABLE FIX FOR H/W LOCKED PHONES
SEE THIS THREAD - THANK YOU untermensch
http://forum.xda-developers.com/showthread.php?t=804305
METHOD 1: ACCESSING DOWNLOADER/RECOVERY:
(if the following directions do not work... then your phone may be locked out from using hardware buttons to access downloader/recovery)
Download Mode:
With the phone powered off
Plug in the USB cable.
Turn the phone on it's side and use both thumbs to hold (left thumb) Vol Up and (right thumb) Vol Down
Press and hold the power button with your right index finger til you see "Virbant" release the power button and it should say Downloading.
Recovery Mode:
With the phone powered off
UnPlug the USB cable.
Turn the phone on it's side and use both thumbs to hold (left thumb) Vol Up and (right thumb) Vol Down
Press and hold the power button with your right index finger til you see "Virbant" release the power button and it should be on the recovery screen.
METHOD 2: STUCK AT VIBRANT SCREEN:
(and are not able to use vol+ vol- methods to access downloader/recovery)
You will need the samsung ADB drivers installed for your phone as well as ADB...
ACCESS DOWNLOAD MODE
1) remove back cover and take our sim card and sd-card.
2) take out the battery
3) hold ALL 3 buttons down at the same time. (Vol +, Vol -, Power)
4) while holding down those 3 buttons put the battery back in
5) continue holding all 3 buttons until the vibrant disappears and reappears... once it reappears, release all 3 buttons
6) Setup ODIN and get it all setup and ready... (if you are flashing your phone via odin)
6) now connect your phone to your pc via USB cable
7) open a cmd prompt and navigate to the folder with ADB and type ADB REBOOT DOWNLOAD
8) Your phone will reboot into the download screen... go back to ODIN - A com port should now appear for your phone...
9) Click start and wait for your phone to do its thing
ACCESS STOCK RECOVERY
1) remove back cover and take our sim card and sd-card.
2) take out the battery
3) hold ALL 3 buttons down at the same time. (Vol +, Vol -, Power)
4) while holding down those 3 buttons put the battery back in
5) continue holding all 3 buttons until the vibrant disappears and reappears... once it reappears, release all 3 buttons
6) now connect your phone to your pc via USB cable
7) open a cmd prompt and navigate to the folder with ADB and type ADB REBOOT RECOVERY
8) Your phone will reboot into the stock recovery and flash whatever update.zip you need
METHOD 3: STUCK AT PHONE ! COMPUTER:
Plug in the USB cable.
Turn the phone on it's side and use both thumbs to hold Vol Up and Vol Down
Press and hold the power button with your right index finger.
The screen will go black, continue holding.
The screen will come back on, you'll see the same Phone to Computer icon
Continue holding, the screen will go black
The screen will come back on, you should see "Vibrant" release the power button and you it should go into Downloading
METHOD 4: STUCK AT PHONE ! COMPUTER:
(and are not able to use vol+ vol- methods to access downloader/recovery)
CALL TMOBILE AND BEG FOR THEM TO REPLACE UR PHONE..
METHOD 5: ODIN ERROR - ODIN HANGTHANKS EUGENE363)
When you can't get into Download MOde....
assuming you just got a Hang in ODIN Flasher...
1. Un-plug usb from Phone ( But still plugged into the Computer )
2. Pull Battery
3. Let the Phone sit for 15 to 30 seconds
4. Plug in USB to Both Phone & PC if not already
5. Hold Both Volume Buttons
6. Put Battery in while still holding Volume Buttons.
My Phone is HW Locked as well, with a v1 board.
every-time I get odin hang, doing the above always results in letting me re-flash.
Interesting! I'll give it a try.
UPDATE: I have successfully reflashed my vibrant... now I will reinsert the SD card and SIM card... and back in business!!!
I am 100% positive my phone was a newer "locked" model... I was unable to access the downloader OR the stock recovery and out of frustration.. I figured out how to access ADB and reboot my phone into downloader or stock recovery!
Hope this works for everyone!
For those of you that just want to test this method out... it does not seem to work for me now that my phone boots past the vibrant screen.... this method only seems to work if you are STUCK at the vibrant screen...

I wonder if this will work for people that are stuck at the computer ! screen... I am unable to get to download mode or recovery with the vol. buttons. tried all the methods that i can find in the forum.
That sucks... give my method a try play around with it... follow the guide.... see if the computer ! screen flashes... if it flashes.. release all three buttons when the computer ! screen reappears and see if it shows up when you connect the USB cable and type adb devices

Oh, I don't have the problem. I'm just thinking if this will work for it. This is the main reason why i'm not messing with different roms/firmware until i can figure out a sure way to get into download if anything would to go wrong. As of right now, i'm just rooted and running Vibrant6. Will not go any further until i figure out the download mode on these newer batch.

This actually does not work for me. I have to 1) Pull the battery to make sure the phone is off, 2) Put it back in, 3) plug into USB, and immediately press and hold vol up/down.
Or ADB Reboot Download, but only sometimes.

If you are about to immediately press and hold up/down you are clearly not using a locked phone... and believe me.. this method works.... i tested it out about 10 different times trying to make the how to as easy as possible... if you are STUCK at the vibrant screen... how were you accessing ADB?
LIKE I SAID... This seems to only work for phones that wont boot past the VIBRANT screen.. My phone is locked out of hardware access to downloading mode and recovery... If you arent locked out of hardware access... then this would be a pretty irrelevant GUIDE..
Here is what makes me believe I am locked out of hardware access... when I follow any of the tutorials on how to access download mode... my phone just flashes and goes back to the vibrant screen... or back to the battery.... it NEVER does anything else...
can anyone confirm that that is what happens with "locked" phones?
I have seen a few posts... in this thread as well as the general Q & A thread .. regarding people having this exact same problem... and having to take their phone back to t-mo to swap it out..
Heh seems like a lot of work. Here's what I normally do and always get into the desired mode.
Download Mode:
With the phone powered off
Plug in the USB cable.
Turn the phone on it's side and use both thumbs to hold (left thumb) Vol Up and (right thumb) Vol Down
Press and hold the power button with your right index finger til you see "Virbant" release the power button and it should say Downloading.
Recovery Mode:
With the phone powered off
UnPlug the USB cable.
Turn the phone on it's side and use both thumbs to hold (left thumb) Vol Up and (right thumb) Vol Down
Press and hold the power button with your right index finger til you see "Virbant" release the power button and it should be on the recovery screen.
Get to Download mode while displaying the Phone to Computer Icon"
Plug in the USB cable.
Turn the phone on it's side and use both thumbs to hold Vol Up and Vol Down
Press and hold the power button with your right index finger.
The screen will go black, continue holding.
The screen will come back on, you'll see the same Phone to Computer icon
Continue holding, the screen will go black
The screen will come back on, you should see "Vibrant" release the power button and you it should go into Downloading
Yes... my method seems difficult... BUT IT IS ALSO FOR NEWER VIBRANT PHONES THAT CANNOT ACCESS DOWNLOAD OR RECOVERY VIA YOUR METHOD OR ANYONE ELSES METHOD... because t-moble disabled hardware access...
That is exactly what happens with my phone. Either reboots or goes to the battery screen.

Well hopefully between your method and mine.... nobody should have a problem accessing the downloader.... I have tried your method about 15 times with zero success accessing downloader or recovery... and I am pretty savvy... not sure what the differences are between our phones...

I just got new Vibrant and everything works fine. No need for any of that.....just have to hold volume buttons and release power button at the exact specific time with usb pluged in, phone goes straght to download mode.
RIP vibrant
just tried this method, and it didn't work for me. My Vibrant has the phone-!-computer error and it's the newer phone that doesn't load to recovery/dl mode via hard keys. I so happened to be loading a rom using odin and unplugged it because the process didn't show a status bar, it basically sat there doing nothing. Once i unplugged the phone it showed nothing but that error message on power up, hardreboot, charging ect. Thanks, tmo for locking hardkey recovery mode =(

had this happen twice and those steps worked for me both times:
"have your usb in, press down both the volume up/down toggle and the power button.... hold them until the screen goes black and as soon as it does, let go only the power button and it should appear there again
however, i found out that you need to take out the battery and get into download mode freshly again...."

This is exactly what I do on my phone. Actually had to do all three of this last weekend when I made a bonehead move and damn near bricked my phone. ODIN and Titanium backup saved my bacon.
I still do not fully understand this whole disabled recovery access thing. Has Samsung acknowledged it as a bug or a new permanent change? I heard they were going to fix it in the Froyo release?
I am unsure of what phones are locked and which ones arent... its kind of weird that some phones are locked out... my question for Eugene or JAC...
Is it possible to take an unlocked phone... and flash everything over to a locked phone... "unlocking it" so that the hardware buttons work?
and by unlocked I mean... able to access downloader/recovery via hardware buttons...
Those of you that ended up on the Phone ! Computer screen... if your phone is hardware locked... you are screwed... the method I originally posted only works if your phone will at least boot to the Vibrant screen (and have a hardware locked phone)
If your phone is not hardware locked... you can follow the millions of posts telling you how they access download mode... no need to follow my guide
Recently, I bricked my phone due to the hardware recovery/download feature being disabled.
Sitting here waiting (for 3 days) for the prepaid UPS return sticker from TMo I had a thought...
What if TMo/Samsung did not actually lock some of these phones down.
Follow along...
In the past, every single phone that I have ever owned would power up via USB connection (from the wall) even if the battery was not installed.
Tonight I noticed that my Vibrant will not power up unless the battery is installed.
USB (from PC) - Battery = No Power
USB (from wall) - Battery = No Power
Battery +/- USB (any) = Phone--!--PC icon
If someone who has a fully functional Vibrant (hardware recovery/download feature works) could try this out?
I'm curious to see if this is a possible pattern...
People keep saying to hold power in some way or another to get to download mode... You dont need to ever touch the power button!
Turn phone off, plug usb into computer, hold both volume buttons in and plug usb into phone. It will instantly go into download mode.

Ive discovered this by accident but while the phone is in standby modus and and the screen is locked, when you press the powerbutton for ~5sec the phone reboots.
In my opinion the "reboot" function mapped to the power button should only be working when the phone is screen unlocked.
Is this a samsung or android thingy?
what do you mean by stand by mode ? when screen is off and not being used ? this doesnt happen on my device...
just dont press the power button for 5 seconds and hey presto !!! job done lol
isn' tthis good feature?
It may help a little when
a. not able to 'wake-up' a sleeping phone
b. upon waking-up , force close message keeps on appearing
In b, i have to take out battery and when using my case-mate barely there cover, it's inconvenient to pry it open.
oops.. I didn't answer your actual question.
Sorry, dunno if this is Samsung thingie or Android thingie. But I can "reproduce" the effect on my phone.
It's not reboot though - it goes to "switch off" mode

mine comes up with a message to shut down the phone or enter flight mode or silent mode or data network mode if you hold down the power button for 5 secs in stand by mode.
If your not getting that message first its possible that your firmware is faulty or if its not a stock firmware it may have not been added correctly.
same here i get message.. stock jpy with speedmod kernel
No i meant like for example you put the phone in your pocket like you normally do and the powerbutton gets pressed for ~5sec while your bent down or another position the button gets pressed it would reboot. Im not really happy with that happening would you.
Im on stock js3 onlything i mod was putting the voodoo kernel on it.
Its a good thing
You'll be happy when the phone freezes and you don't need to take it apart to reboot it (pull battery)... Its just like a power button on a PC, if you hold it long enough it shuts the device down. I've never done it by accident though. Just get a $.99 plastic case and your problem will be gone but you'll still have the feature.

Brand New VZW Note 5. Couple of times a day, my Boot Maintenance screen shows up. Not sure why this is happening. I have to use the volume button to toggle to the reboot normal choice and then select via the power button to escape from the Boot screen. I thought you had to access this by powering off and powering on by holding the volume up and power buttons together during restart. What gives?No idea how to stop this annoyance.
Let me guess...you have a case on it? It's the case. It's either pressing the power and volume buttons just enough or its the kickstand that you may possibly have on the case.
Hello!
Not later than this morning I realized a problem on my Idol 4. At random moments it restarts. When it is on the screen of starting up it continues to restart in a loop. I came to the conclusion that it is a problem with the power button because when I press the volume buttons to enter download mode or even recovery, it quit the download mode (which is done by pressing power) and select options automatically in recovery (which also done by pressing power). So when it restarts I just press the power button randomly, try to pull it out of the phone and then it stops restarting. But again, minutes later it restarts... The button seems not broken or anything that kind but maybe it's in the inside ?
So just questionning how can I fix this.
Thank you a lot !
I think you can just pop the screen off and buy a replacement the idol three was pretty easy to replace. No special tools just used my nails
Here's a quick reference for how to reboot and reset your 2019 Galaxy Tab A 10.1 (SM-T510/T515) using the hardware buttons:
Force restart:
- If your device is frozen and unresponsive, press and hold the Volume Down + Power keys simultaneously for more than 7 seconds to restart it.
Boot to Recovery Mode:
- Power off the device
- Press and hold the Volume Up + Power keys at the same time.
- Release both keys when you see Recovery Mode.
Boot to Download Mode:
- Disconnect the USB cable
- Power off the device
- Press and hold the Volume Down + Volume Up keys
- Insert the USB cable
Boot to Safe Mode:
- Power off the device
- Press and hold the Power key.
- When the boot logo appears, release the Power key and then press and hold the Volume Down key.
- Continue to hold the Volume Down key until the device finishes restarting.
- Safe Mode will display in the bottom left corner of the screen.
Since there is no Bixby button, these combinations are different than the Galaxy S10. If you know of additional combinations, please contribute to the discussion below and I'll consolidate here.
If there’s no response on your device or you're stuck in a boot loop, then you might need to wait for the battery to drain. The 2019 Galaxy Tab A 10.1 has a non-removable battery pack, so disconnecting that isn't an option. Hopefully, the system reverts to its normal function with a cold boot. This can take time if the battery has high charge left at time of failure. Depending on how fast your battery drains, this can mean waiting for a few hours to several days.
UPDATE: With the right timing, you can break out of a boot loop into Download Mode...but it's tricky:
Insert USB Type C cable connected to your PC
Press and hold the Power and Volume Down keys for exactly 7 seconds (hard reset)
Release the Power key and press and hold both Volume Up & Down keys (enter Download Mode)
If you don't see the blue bootloader unlock warning screen, keep repeating the above two steps
The trick here is that you're trying to time your switch to the Download Mode keys for the exact moment the hard reset takes effect. If you see the boot logo while still holding the first key combination, it's too late. If you switch too early, you won't trigger the hard reset.
I've had to hold down both volume up and volume down while plugging in usb to get the unlock screen to populate. Canadian Wifi variant.

Thanks, that was an error in my initial post. I was figuring these out by trial and error, but it turns out that our hard resets are basically the same as for the Galaxy M30, which also uses the Exynos 7904 SoC and has no Bixby key.

UPDATE: Also the same as for the Galaxy A30 and some others.

Yes, I did the same way
US version
1. Enable OEM Unlock
2. Turn the tablet off and unplug the cable
3. Press and hold both volume up and volume down buttons and plug USB cable to host computer
4. You will get wipe screen. Long press volume up to unlock the bootloader.
Now I have to find matching ROM and patch the boot.img and flash.
I believe you have to disable Vault Keeper to keep root intact.
Brand new out the box 11am this morning.
Opened the parcel cool no damage. Powered up fine, had a mess with it, no problems check the speakers were fine and no issues plugged it on charge to 100% took it off and left it for an hour or so, went back to it and physically used it to use Facebook and play candy crush cool no problems. Took a few photos and no problems again. Put it on the side still on near 90% and went back to it 30 minutes later completely off and won’t turn back on, tried charging it nothing no sign of life, tried rebooting it and still nothing. Please tell me that this is not the end and I need to get a replacement... ?*

Have you tried getting into download mode? Or recovery for that matter.

I’ve not even been able to get it back on, I’ve attemp a reboot countless of times and still nothing rectifys it. I spoke with Samsung they feel it’s a major fault with the tablet and have told me to request a replacement from my provider or even a refund.
