The Tab is in an endless reboot loop.

I had the same problem with continuous rebooting. The problem seems to be a sticky power switch, as others have suggested. I didn't want to take my tab apart to disconnect & reconnect the power switch, so I just thumped the back by the power switch to unstick it. That fixed it and it booted normally afterwards! No data wipe, no factory reset, no repair center, just a few quick thumps to the back under the power switch!! Good luck!

Hello,

hopefully your tab is fixed by now, but if it isn't, there is an easy way to fix it. You just charge the tab to 100% while it is off, then reboot it. You will lose all of your wifi passwords for some reason however it is a small price to pay.

Hi, open your device and after samsung boot screen:

disconnect the power switch flat cable (the one that had also the volume switch in it), probably it wont reboot automaticly anymore, worked at 2x p3110 for me.

Good Luck.

Step 1: Power down the device. Pulling the battery will work as well, especially if you are caught in a boot loop.

Step 2: Allow the device to completely shut down. Waiting until your screen is off, or just giving it a full minute or two should suffice.

Step 3a: For the Galaxy S2 and Tab 2, you will need to hold Volume Up and Power at the same time until you see the Samsung logo appear. Then release.

　　3b: For the Galaxy S3, you will need to hold the volume up, home, and power button at the same time until you see the Samsung logo, and then release.

Step 4: For all variants mentioned, you should now be looking at a menu list with a blue highlighted bar. Using the volume rockers will navigate through the menus, and generally power is your accept button. The S2 might have a little twist. Upon getting into recovery, you can push up, down, up to enable the back button. This also allows to use the power button as the accept button. See figure 1.

Important note: When navigating around in recovery and you select something, you may be redirected to a page with about a dozen answers. Almost all will be no with yes buried in the middle. This is to prevent accidental accepting of an option.

4b: To actually have you use this guide, you can clear your phone's cache. See figure 2. There are many cache clearing programs on Play, and while they may clear the cache as well as rebooting into recovery, this is merely an alternate method. Click power to accept.

Step 5: When completed, you can navigate back, or usually after completing any action in Recovery, Reboot Now will be highlighted at the root menu. See figure 3. This is your gate back to running Android through the User Interface. Click power to accept.

Congratulations! You have successfully entered, navigated, executed a command and rebooted all in Recovery. This is also a method to flash a ROM through a .zip file on an SD card, and a complete Factory Reset can be accomplished in this manner as well.

hold power button and left togle together (not right togle)

open the back of the tablet, get a little screwdriver and remove the screws from the back of the battery, then remove the battery while it's

on, then put it back. Also, put the tablet back on.

I had the same, but solved it. After booting it started to reboot after 10-20 seconds and this repeated continuously.

Please try this, after rebooting disable the wifi in the settings of your tablet.

If after disabling the wifi the tablet does not reboot than that is the issue.

How to solve?

enable the wifi again and remove the connections you are using or may use, starting first with the one that is connected (since otherwise the tablet will reboot before you have removed it). Than remove the others which you may use.

Also remove the tablet in your router from the list of connected devices (I am not sure it is needed but I did that)

Now reboot the tablet yourself.

In the settings of the tablet you see all your connections appearing again under Wifi.

Connect to the wifi connection (SSID) you need (you will likely have to input the key(password)).

Now the tablet does not reboot anymore automatically.

this is really obvious but have you tried changing chargers or anything? When it tries to reboot does it make this strange beeping noise? It did with me and every time it stopped the screen would flash for not ever a second and would go back out! So I changed the charger to one of the ones I got in the box and it turned on! However what I learned that when my tablet turned on it was trying to turn on it just didn't have an battery life! So try to change the charger to one that has the white lightning bolt instead of the one with the white lightning bolt with the "x" over it (even though it may charge like that) and make sure its a good outlit

replace the battery.Its easy to do. My tab was left in my cold car with a low charge.It would not charge after that and i read somewhere why a low charged battery will cause a loopboot. I bought a new battery and fully installed it then fully charged it.After that my Tab booted right up

After upgrade to Android 5.1, my Samsung Tab S 8.4 was flickering and rebooting when battery goes under 65-70%. I have tried many things but nothing worked. Finally, I put my tablet in "economy mode" and this solve the problem. Hope this solve yours problems too.

I had this exact same problem. No advice about thumping the back, nor would it boot to the recovery screen by holding buttons down and all that (3 different variations attempted). I tried disconnecting the battery and still nothing. Mine kept appearing like it was trying to charge, but then kept rebooting, even while plugged into a charger, left overnight and all next day.

What worked was using the OEM charger. I was using an aftermarket charger, but this isn't powerful enough to get the required "umph" when the battery was completely dead. The charger I was using worked fine while the battery had some charge on it, which is why I didn't think this would've caused the problem, but made sense afterwards. Good luck.

You need to completely disconnect the battery from the tablets Motherboard, and then reconnect it.

My Girlfriend has a 10" Galaxy Tab that does this constantly when she forgets to plug it in to charge.

I take the tablet apart, pull the battery cable for 5 seconds, plug it back in, and it works WITHOUT losing everything!

The way I fixed my galaxy tab a was since none of the buttons worked while in the reboot loop, I couldn't hard reset it. The reset button didn't work either so I left my tablet alone and waited for it to die. Then after I plugged it in, I started it up and it works again.

I answered this previously saying to try using the OEM charger, but mine just started doing it again, but I don't have the OEM charger anymore. No other charger worked, but I fixed the issue doing this:

1. Pull back cover off with spudger. http://www.techrepublic.com/blog/crackin...

2. Unplug battery. It's the connector one with red and black wires.

3. Press the power button, and hold for 10 seconds. Use your spudger or fingernail.

4. Plug battery back in.

5. Plug charger cable back in. You should see it charging again.

6. If not, repeat steps 2-5. Otherwise, snap the back cover back on!

I HAD the same problem. The unit would go into a continuous reboot cycle until I plugged it in. Fixed it by following someone's suggestion to remove the battery and re-seat it. Have not experienced the reboot problem since and that was over eight months ago.

When you plug in the battery, before turning the tablet on, try holding down the volume up or volume down button: This May put you into a download mode in which you could use your PC to re-flash it (If one doesn’t work, unplug battery for 10 seconds, plug it back in, press and hold a volume button, tap power button)

so I decided to shut down my new galaxy book 2 and it’s stuck like this :/ what do I do?

I have a Galaxy Tab A 10.5. I tried updating the software because it wanted me to. Now it’s just cycling the Samsung logo like an endless boot loop. I can’t turn it off. Or on for that matter. I have tried the tricks with holding the power and up or down buttons for up to two minutes each. Didn’t work. There is no home button to try. Only power and volume. At this point I’m ready to throw it out and buying a new one. All the google searches I have done have come up with “solutions” that involve either turning it off, which is not possible, or using the home button, which doesn’t exist. Anyone has any advice?
