My Samsung Galaxy Tab is stuck in a reboot loop, how do I fix it?

Hurray, Android! My parents and grandparents are in town this weekend, so I thought I'd share some of the latest technological wonders with them. I pull out my Google I/O Samsung Galaxy Tab and turn it on, only to find that it's now in an endless reboot loop. There's no way to get out of it. What the heck?

So, how do I fix it? Is my tablet bricked? Or is there an unnecessarily difficult way to restore the firmware (after all, Android) and get this thing working again?

If you hook it up to a computer you can fix it. It will probably take some more googleing once you figure out exactly what went wrong.

Hi Dave ,
I dont know if you have all ready fixed your problem with the reboot.
But i had the same problem and it kept re-booting, and yet when it came into the operating system, it would freeze the moment i touched any icon and re-boot over and over again.
I dont know why or what caused it. But how i fixed it was...
1. Connect the charger cable to your tablet while it's in re-boot mode.
2. Connect it to the power source.
3. press the power off button for around 6-7 seconds until the tablets powers off.
now you think it's going to reboot again, but this time it should not, and you would see the battery charging sign appear on the screen and no reboot.
4. Just allow the tablet to charge fully.
Once it has, it should start working.
I dont know why but this is how mine got fixed after hours of rebooting.
Cheers.

Never heard of that before. If it were me, I'd let it run itself completely out of battery and then just start it up and see if it's gone.

You could also try holding down the power button for 12 seconds (or however long a hard shutdown is) to try and get it to shut off. Then start it back up again.

Also, why would restoring firmware be unnecessarily difficult because it's Android? I know you hate Android (in an unfounded way, much of the time) , but even on Android, resetting (soft and hard) are both available options in the settings menu or via buttons. You can do a factory data reset or just restart the phone. Restoration on Android has never been an issue. You even get your apps back via automatic downloads when it's up and running again.

i had encouter the same, every time the tab start keep reboot, i would factory reset the device as i got google restore, it' only a half pain exeperience. Lately, i figured out it was a bug, when my tab keep trying connect (showing, obtainning ip address from XXXX)to my home wifi it would reboot, if i shut wifi on my tab, no reboot, then i discovered when i just restart my home wifi router, which the tab can get connected again and won't restart. So it seems as long as my tab can successfully connect to a wifi router it will be fine.

I had to do this for the second time and it wasn't the solution that was picked for the top answer, so I thought I should drop the link to the instructions that helped me fixed this issue: www.galaxytabforums.net­/forum­/galaxy­-tab­-10­-1­-help...

You're going to need a Windows PC and also have to download some files (included in the link), and install some stuff. The major caveat with this method is that it's basically a factory reset, so you're going to lose all of your data. I'm hoping I won't have to do this again!

Try booting into recovery or HBOOT (on most phones volume down + power but I'm not sure with tablets). Also, have you installed any custom roms?

Had the same symptom (reboot loop), after some tests (cleaning device cache in recovery mode, press power button for a long time) finally found the problem was on the SD card. Removed the SD card, formatted and problem solved

I had the same problem i.e. my Samsung Galaxy Note 10.1 GT N8000 kept rebooting itself into Samsung Galaxy Note 10.1 logo. After the power was drained out, when I tried to charge it the Battery Charging logo came on screen but it seemed to be stuck indefinitely and the charger became really hot. At first I thought it could be the charger problem so I tried with my other samsung charger but the symptoms were the same; the charger and the cable became really hot and the battery charging logo status seemed stuck.

I tried the Power + Volume Down buttons combination but it could only get the unit into ODIN mode. For quite few days I tried different ways in the hope of powering it up but to no avail. So I kept searching for more info and there is a thread (I don't remember) that I came across and I tried the solutions and VOILA it worked!

Before I elaborate how I did it, let me tell you as to why this symptom happened. It seemed that after I left my Samsung Galaxy Note 10.1 for almost a week, its power became completely drained out. So whenever I tried to turn it on, it did not have enough charge to power it up. Second, it seems to me that the charging process is controlled electronically from the inside tablet by some kind of chip. So if this chip has problem then the charging process is not possible or 'not accurate.'

So here is what I did (after some research):

I reset the internal electronic chip that controls the charging process. This might sound difficult but it was not. All I had to do was to remove power completely from the chip by removing the battery pack cable. The instruction on how to crack open the back cover of a tablet or note can be found on the Internet; there is plenty.

In my case, I tried pushing the power button for a while with the battery pack cable disconnected, just to make sure, you know, it cleared up the chip. Then I put the battery pack connector back in its slot and connected the charger. (You might have to do this a couple of times. I did it twice). I turned the charger on and VOILA! the Battery Charging Indicator logo animation came on screen normally and the CHARGING WAS ON! I was happy to see this. I let it charge until the charging logo shows FULL. I turned it on and it was a SUCCESS. I turned on and off a couple times to make sure it really works. I assemble the unit back and it works like NEW again. Maybe I will reset it to factory setting as I have downloaded quite a number of apps already. ;).

Having said that, I want to make it very clear that opening/disassembly of such unit is at owner's risk. I just wanna share my experience. I could not send my SGN10.1 unit back for repair since it is already out of warranty. So my best bet was to open it by myself since I am pretty sure there was nothing wrong with it the last time I used it. Good luck and happy troubleshooting!
