The Tab is in an endless reboot loop.

My Samsung Galaxy Tab 2 7.0 is turning on and off continuously. I connected it with the charger and I pressed the power button. This is stopping the endless reboot, but when I try again I'm faced with the same problem.

The battery is 100% full.

How do I fix it?

Hi,

Did you try a factory reset?

You can do this from the Android Recovery Menu (this will erase all your personal data!!!)

Press and hold both the "Volume Up" and "Power On" keys until you see the Android logo.

Use the "Volume Up" and "Volume Down" keys to navigate through the menu, and use "Power On" for OK.

Choose "wipe data / factory reset", then "yes erase all data," and finally - reset.

Factory Data reset / Hard reset

Regards.

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!

blowing compressed air around the power button can also free it but if it doesn't work you need to solder in a new power button

из

Thank you for this suggestion! It worked for me.

из

I tried EVERYTHING including full factory reset, special key combinations and replacing the battery...no help. Then, out of frustration I slammed the tablet flat against my kitchen counter - really hard. Now it works fine.

из

I seriously just laughed when I saw this solution, so for a quick giggle I gave my tablet a good few soft hits to the back near the power button... apparently this actually worked. Thank you very much for the help.

из

I tried this out of desperation and it worked! thanks for the suggestion!!!

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.

Regards Joel

Samsung Tab 3 8inch

I was having many of the same issues above. ( cycling on and off, after shutdown it rebooted, did a factory reset that didn't do it, the charge lightning bolt would be on when unplugged I thought the I fried the battery ( kinda new) watching movies while charging. Took the battery out, out it back, no change. THEN ... I took a close look at the USB port port looked a little "stretched out" I remembered that I had dropped the Tab while connected and it had bent the wire connect. With the battery out I went after the port. first compressed the screwed in steel plate in. Inside the port there is a small metal flap and bent that up away from the base of the port. I Putting a wire in the port was very tight. Put the batter back plugged it in and voila - started charging and all is well.

The bottom line: my issue was the out of shape USB port. It would not make a solid connection . It made a connection but I would guess kinda of a shorted out connection.

Thanks!!! I have disconnected power switch the device is rebooting continously anymore

My question is that should I connect the power cable back

из

After I disconnect the power switch cable my device is not rebooting continously anymore... Should I connect the power cable back

из

The power switch is defective. You need to change the cable assembly.

из

what do you mean by open your device? open the back cover?

из

I can't open the back how do I do that

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.

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.

With deliberate care, I removed the back of my SM-T320 (pro) removed the 4 battery screws, carefully unplugged the friction fitted wire harness, to access the battery and motherboard connections. Also, there is a wee Tae covering the harness that I removed, and added back later, using scotch tape.

Using air cleaning canister for electronics, I cleaned the power button and the battery contact points, then used brake cleaner fluid (acetone) to clean these areas. I puffed out a wee black fleck of ?, at the battery connecting points on the motherboard. Battery was reconnected, back snapped into all those micro points, recharged, and, no more spontaneous rebooting, so, I'm declaring this cleaning process to be successful - so far.

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.

Truthfully, sometimes the tablet is just dead. You will not always be successful doing a factory reset and battery change out- sometimes the logic board or other components are defective, and it's simply not worth fixing.

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)

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?

It's likely that your logic board has failed, and it really isn't worth fixing at this point. I had the same issue.
