So I decided to unlock/root/flash a ROM onto my 10.1 (wifi), since it went so marvelously with my Galaxy Nexus I figured "lets flash all the samsung devices in the house!"
Anyway, when I hold down power and the volume down button, the tab boots to the "Galaxy Tab 10.1" white logo, shows it for a couple seconds, goes dark for a couple seconds, shows it again, and cycles thusly forever (well I did it for about 5 minutes straight). Any idea how I can break the cycle and/or a different method to boot into downloader mode?
Also, if I let go, it shows the white logo one last time the boots normally into 3.2.
Release the power button when you see the Samsung Galaxy Tab 10.1 logo without leaving the volume button
Great success, thanks!

half alseep, i attempted to update my tab the "official" way with the software update options. it downloaded in the background pleasantly enough, then prompted a reboot, ok i said.
after seeing that good old galaxy tab 10.1 boot logo, the logo was replaced with a slightly larger one.
for a split second i saw a load bar at the bottom of the screen, i only saw "9%" before it vanished, replaced with a totally black screen
"that's fine" i said "probably just silently installing"
twenty minutes with no change later i was getting worried
i did a hard reset (holding the power button for 8 seconds) since that's basically all i can do.
it got to the boot image and went straight to a black screen with the backlight on, same as before.
i attempted to get into recovery (power+volume down) but the green android never appears, it just cycles through the boot logo over and over again.
plugging it in doesn't work, my system doesn't see it at all as far as i know
plugging it in and trying to boot recovery also does not work
is it bricked?
i don't think i'll ever do official updates ever again, this is pitiful
badumtss. This is why I hate kies. Basically when you boot it up, it goes directly to black screen is it?

not quite, it displays the original boot logo (the slightly smaller "galaxy tab 10.1" logo) for a few seconds before going to black screen
Are you using correct technique to get into recovery/ download? If you keep holding the buttons down it will just keep cycling through boot as you describe. Did you release as soon as logo appears? Sounds like your hard reset interrupted the update and you're missing full boot partition or system partition. If your " hold down the buttons" was at fault and you do get into recovery etc maybe odin is the way forward... just a thought. Also your long press on power might be putting the tab in apx mode, have you tried that and then seen if it is visible to nvflash?

more data;
i let the battery run down to zero after reading some technique to un-brick which required it, until i just read here about how recovery is when you let go of pwr+vol down right as the logo pops up, not waiting for the green android logo.
so, i plugged it in and tried that.
the result is;
it'll power up, show the battery charging image with the little loading circle (i guess it's fetching the battery status) but the battery status never loads. instead it flashes the galaxy tab 10.1 logo for a split second and then back to the black screen of death.
i'll attempt again when the battery has more juice
damn!
after letting the battery charge up some more i tried going into recovery again.
same problem;
hold down power and volume down (the side of the volume rocker closest to the power button)
wait for the logo to appear
as soon as "samsung galaxy tab 10.1" appears, i let go
but it STILL sits there for a second, then flashes the slightly larger boot logo before going to a black screen
damnit damnit! do i have a paperweight? i really want to punch whoever authored that update.
EDIT: a possibly related issue, i cannot turn off the tablet anymore. if i hold down the power button to turn it off, it just cycles back into a boot.
Might wanna try my draining method, I posted it somewhere here, must be in page 3-4, Ill bump it up
I'm having a similar issue, basically everything the same except it doesn't go black after the logo comes up, the back light gets slightly brighter and the logo stays there. It also wont turn off, unless I have it charging then unplug it.. the update was interrupted by me accidentally going into recovery(at least I think it was. It could have just been by pressing the power down because I haven't done a system update before, so I don't know what all happens), then it went into download and was stuck on the odin interface. I did a hard reboot, and then it started buggering up. How does an update interruption brick your tab? What kind of person makes something that can do that.. lol.
OK! Problem solved guys, sorry for "spamming", lol. Just flashed it back to stock.. now to try different ROMs for the first time. Thanks!
Ok, A friend needs to me fix there galaxy note. It will boot to the samsung logo, then to the greener samsung logo, then the screen just goes black. I can get it into download mode, but after like 3 seconds the screen goes black also, and the pc dont reconize the device at all.. if i plug the usb in.
any suggestions, ive never seen this before.
How is your battery? Was the phone rooted? What was done to cause this?
Sounds like a stuck power button. Try tapping the power button quickly a bunch of times. Or try flicking the back of the phone by the power button with your finger.
So I had my Galaxy S5 from T-Mobile for a couple of months and it has been working great, especially after the recent Marshmallow update. But as of late, my phone would crash and keep restarting until it starts up normally again. Over time, it would get progressively worse and it would take longer to boot up over the course of a couple of days, and when it does finally manage to boot up and work, pressing the power button would crash the phone and throw it back into a boot loop. I left the phone alone for a couple of days and came back to it to try to boot it up again, and it worked well! It booted up first try without any kind of restarts and the power button worked a couple of times until... it failed again when I pressed the power button and it got stuck in a boot loop again. And after a couple of minutes of being stuck in a boot loop, it would boot, but the screen was black. The LED at the top of the phone and the lights from the capacitive buttons would work and I know the phone is working it's just that the screen is not. I can manage to turn off the phone without the screen by holding the power button and guessing where the "Power Off" button is. And while the phone is in this state, when I press the power button the phone would lock like it's supposed to. I've tried taking out the battery and holding the power button for 2 minutes and letting the phone rest for another 10 minutes but it doesn't seem to really do anything. I've tried rooting it before but failed to, but I don't really think that's the problem. If you guys have any suggestions I would really appreciate it! Using my old Galaxy S3 is kinda annoying, especially since Pokemon Go doesn't support it. Thanks again!
If you guys would like a video of some sort to see what's going on exactly then I'll be glad to make one for you guys.
Did the problem start after you tried to root? What did you use to try and root your phone? What baseband are you on? Do you have stock or a custom recovery?
From past experience, symptoms indicate a stuck power buton. FWIW.

Hi,so i replaced LCD in my I9515, I've been doing this with youtube tutorial. Before 1-2 weeks ago my phone boot normally but i couldnt see anything due to broken LCD. In store, guy took my battery and connected it to a naked motherboard and lcd to see if it's working. After replacment when i try to boot it's stuck on Samsung Galaxy S4 logo and wont boot further. I can go into download mode, computer and odin are seeing connected phone, but i cannot boot into recovery it's just showing blue "booting recovery" and nothing happening. When I charging it, the grey battery pops out, but when i unplug it the battery is still there like it's still connected. Sometimes when i try to turn it off when it's stuck on galaxy s4 logo it's turning off then on by itself like 2 or 3 times. Any ideas how to fix it? It's hardware or software problem? In a minutes i'll try to flash stock soft from sammobile. Phone was never rooted and no custom roms were installed.
Thanks for all help.
EDIT Flashing with ODIN not solved the problem
EDIT Now phone doesnt show battery when connected just one vibrate and screen is blank, and when i try to boot it while connected it's just vibrating and still black screen. When it was connected to pc it was vibrating every 2 seconds. When I try to boot it's by itself trying to boot recovery but it's not booting and blue "recovery booting" just hang on top of screen and nothing happening.
EDIT After restart by volume down in download mode S4 acts like in the beggining of problem
EDIT It's getting hot around processor when charging (about 5-10 min)
My galaxy s6 edge has been stuck in a boot loop. I have not dropped it or anything. Last night, about 12 hours ago, I took it out of my pocket and it wasn't turning on. Once I got home and plugged it in, I was relieved to see the charging indicator. However, upon returning about five minutes later, I turned it on, only to see nothing happen except the charging indicator flash on the screen again. I then attempted to boot it into safe mode, which brought me to the "Samsung Galaxy S6 Edge-Powered by Android" screen (which is the first thing I usually see when powering on my phone). Normally after this screen, I see the Samsung logo, and then the AT&T logo. But instead the display turned off, and then showed the same screen again. Then it just went into a loop of this sequence. This only happens when it is plugged in. When it is not, nothing happens-the display doesn't turn on or anything.

Flash stock rom through odin to check if you can revive your device. Firmware can be found on sammobile website and odin can be found using Google, instructions on flashing firmware can be found here on xda.
