[Q] Can't get my tablet to boot into Recovery/Download mode - Galaxy Tab 2 Q&A, Help & Troubleshooting

Hello,
Hopefully I'm in the right place for posting something that seems to be this simple. The start of my problem is that the tablet will not stay off. When I try to shut it down, it shuts down normally, but then it starts to display the battery icons like it is plugged in and charging, but it is not connected to power. I can leave it in sleep mode and the charging thing will not happen, but turning it off displays the power charging screen and it further drains the battery. I figured something is screwy with the system so I would try to reset it to factory defaults. Now I have the other problem...
So I am trying to restore to factory defaults and I know to do this I have to start from off and hold down the up volume and the power button for a few seconds and as soon as the tablet starts to turn on release the power button but not the volume up button, and it should get me into the recovery/download screen. Unfortunately that is not working. I hold down the Volume up button and briefly hold the power button (3 or 4 sec or so) and I see the Samsung Galaxy Tab 2 7.0 startup screen and let go of the power button (still holding the Volume up button). Next I see the spinning blue circle around the Samsung logo and the tablet reboots. I can release the volume up button at any time after that and the results are the same, it just reboots. It's like it isn't seeing the volume button.
I have tried using the volume Down button instead of the volume up button but that too is just like I am not pushing any volume button at all. Once the tablet is on, the volume buttons function normally, so the switches are good.
Since I got this tablet used could someone have loaded something onto it preventing it from being rebooted into recovery/download mode? Maybe some custom firmware or something. I'm at a loss as to where to go next. Since I can't boot into recovery/download mode I can't get into Odin.
Any help is appreciated.

Hi. The tablet isn't rooted, is it? Can you try to boot it into download or recovery with the "quick boot" app from google play?

I don't think it is rooted, but I can't tell for sure since I can't connect to the Google play store. I tried downloading using the web browser, but my battery dies before if finished. I'll try swapping batteries and see what I can figure out. Thanks for the idea.

No, the device is not rooted. it also is not charging and I had a heck of a time getting it to connect to the play store. I think I need to try and reload the OS, but without being able to get into ODIN, or reboot into recovery, I'm not sure how to proceed. any suggestions?

When the battery thing appears do the power- volume up thing and hold it until the gtab logo appears.

I've tried that, and it just boots up as if I wasn't holding the volume button at all. Once the tab is booted, the volume buttons work as normal. I've even tried putting a different power/Volume/IR unit in (from a working tab with a broken screen) and that didn't make a difference.
I left the tablet all weekend and it just keeps showing that it is charging when not plugged in. By Monday the battery was 100% dead. It won't even charge. If I replace the battery with a battery from a working unit I'b back in the same place where I can't get it to boot to Recovery/download.

[Q] My Tab Plus Stuck at Boot

Got a tab plus in completely stock condition. Been working well for well over 2 years now. Yesterday I noticed that the screen is displaying "Warning!! A custom OS scan cause critical problems..... Volume Up to continue, Volume Down: cancel (restart tablet)" The screen wouldn't get switched off. Neither the volume up or Volume down or power works. I let the battery completely drain till the tab got switched off. Then tried to charge, after a few seconds of the charging animation, the same screen comes back again.
Tried the Power+volume up, Power+Volume down, Power+Volume up+Volume down combinations. Nothing works. Never had a sim in the device. Removed the sdcard and tried. No luck.
What has gone wrong? Any help will be greatly appreciated.
Bump. Any help will be nice
If you can, try to save everything you want off of it. Then try to factory reset it.

Phone won't boot up

I have researched the "related threads" and none are similar to the issue I am having.
The phone turned off midcall and fails to turn on afterwards. I thought it was the battery, but it still fails to turn on after charging over night.
It boots up to show the logo, after a battery pull and turns back off.
If I I press down the power button + down volume+ menu, I get the warning about a custom install of an OS may damage the phone and if i want to continue to press the volume up, or cancel.
The phone only lasts about 5 seconds, after every battery pull, other wise it won't turn on again.
I haven't gotten a blank white screen nor the Android logo.
Thank you.
Update: I believe I confirmed it is a power button issue.
What I used to confirm it was pressing the volume down button and menu without the power button and was able to see the Warning as if I had pressed all three. Also, the phone vibrates as soon as I place in the battery.
Issue now is: Supposedly the cause is due to a stuck power button, but physically the power button is not stuck. It clicks when pressed.

S7 won't boot, blue LED always on.

Just some minutes ago my S7 froze because of Focus Gallery App. I don't exactly know what it did but the phone did not respond any more.
So pressing the power button did not bring back the phone either. After searching for a bit I found a way to simulate a bettery disconnect by pressing Volume Down + Power Button.
The Phone came back up and displayed the initial boot logo. Also the blue LED is on. But nothing happens from here on. I do not come to the "Samsung" boot animation and the phone simply
does nothing. Retriying Volume Down + Power Button doesn't seem to help too. I tryed all button combinations but nothing brings the phone back.
I also cannot enter the recovery menu. So no chance to reset to default settings.
I am running a stock Android on the phone. Nothing was done by me. No custom ROM, no root, just plain Samsung Android.
Is there sill something I can do?
Edit: I just got into whats seems to be ODIN Mode??? Can I do something from here?
Oddly this happened to me last night although I may have inadvertently done it. But the only way I was able to get my phone functioning again was reflashing the OS to the phone.
How did you manage to get the phone into Odin mode? I'm having the same issue with the phone being totally unresponsive but the blue LED on.
if you can reboot your phone with the VOL Down/Power, when the screen goes black, quickly press and hold VOL Up, Home and Power. it should enter recovery. or hold Vol down, Home and Power to enter the download screen.
I have the S7 Edge (rooted, custom ROM) and it's running fine. My girlfriend's regular S7 is having the same issue though.
When she plugged it in to charge last night, she checked it a few minutes later at which point the phone had (started to) reboot. The blue notification LED was on and the screen had frozen at the 'SA' from the 'SAMSUNG' startup logo. Forced a reboot with down+power, resulting in just the blue LED (no logo this time). Phone was unresponsive (couldn't force a reboot again) so left the battery to drain overnight. The phone is completely dead today even after charging - no LED, no boot, no anything.
I'm not sure if she had the phone scheduled to perform an update overnight and it froze halfway through, but that would be my first guess. So far, no fix.

Galaxy S6 - Cannot proceed past download mode warning screen

I have a Galaxy S6 with a faulty power button.
I took it to a Samsung Repair Centre.
After "diagnosing" the problem (which I had to pay for), I was told that the faulty power button was due to "liquid damage" (it has never been in water everything else works fine).
They said it would cost £180 to repair and would require they replace the whole motherboard.
I refused as I cannot afford that repair and would rather consult a third party shop or purchase a brand new phone.
Unfortunately, the state I received the phone back in unusable.
Before the phone was sent in, it was at least in a state where I could at least use it (providing I kept it charged and did not power it off).
Now its just stuck in a recovery mode => restart => no command (boot loop), and I cannot select an option from the recovery mode screen because the power button does not work.
I planned to flash the stock firmware to try in order to get it out of this loop, and I can get it to boot to download mode as the volume buttons and home button work fine.
However, now when I'm at the cyan warning screen it prompts me for volume up to continue.
I press volume up and nothing happens. I know that these buttons work for a fact as in recovery mode I can navigate up and down.
Any ideas whats going on? or what I should try next?
Videos of the issue
(Tinfoil theory: Did they purposefully lock down download mode after inspecting it?)
If you have time, continuously keep pressing volume up and power until it gets you into Odin. Best of luck.
We're on slightly different devices, but mine has the same defect. The power button failed overnight, it worked to start the device but afterwards, the power button became stuck in the pressed state and I couldn't lock the device (not mechanically, it is still clicky). The volume down button still worked (I don't have to hold power to force a restart because it's stuck in the pressed state), I wanted to take a look at the knox status in the download mode, it didn't respond to volume up, this means that it's dependent on not having power pressed. I somehow got the restart confirmation to show with the power button, twice, so it's not completely defective. The volume down button cycled through being stuck and non-clicky, working normally, and being stuck while being mostly clicky, like the power button, though it doesn't seem to be stuck in the pressed state. It's likely because I kept pushing Volume Down for hours in a terminal emulator. Today, it takes 5 mins of torturing Volume Down to restart the device. Eventually, it might fail completely. This device seems to be able to ignore volume up / down if those buttons are stuck and work almost completely normally.

Samsung Galaxy S7 Will not power up, It showed a samsung logo and hung

My phone stopped working all of a sudden since last night, it was just sitting on the side idle and all of sudden it started showing a black samsung screen and hung and did not respond to any touch or anything else, At this point pressing powering button alone did not turn off the device, so I remembering pressing all of the button simultaneously and that turned off the phone but since then it wont turn on at all. I cant recall if the phone was on charge or not before it hung. But I am 100% battery was charged at least 70%.
After all that, I have tried all the possible combination of hard resetting this phone and still no luck to get it to power up.
Left the phone to charge overnight and in the morning tried restarting again with all the possible combination and still no luck to power up. I am clueless now.
Please let me know what could be the issue?
Any help would be appreciated
Update on the situation:
So Today I tried turning on the phone again and I pressed power+Volume Down+Home button and the phone started and it took me to the download mode. However when I pressed the up button it did not restart and stayed off, I pressed and held the same combition of buttons which are Power+Volume down+Home button then it took me to download mode again but I could not do much other than uploading a new firm to the phone which I did not want to do that. So I decided to restart it again by pressing the up button and it powered off and this time I went and pressed and held Power+Volume up+Home button and it did not do anything I tried this couple of times and still did not do anything. So I tried Power+Volume Down+ Home button and this time the device did not power up again.
At least now I know its not the hardware and some software glitch or a stuck loop.
Can someone please help me with this.
Thanks a lot Guys.
Update again:
Right after putting in the charging cable then the phone started up again and now the phone is showing an android blue screen "No Command" Pressing and holding Power+Up buttons do not bring it into the recovery mode? Please let me know thanks
