constant reboot - Galaxy 3 Q&A, Help & Troubleshooting

my galaxy just wont boot anymore i can only see the boot logo and then restart again try to put it into download mode it boots into download mode but after a few seconds it reboot again into a boot loop.i tried to pull out the battery but once i put it back again it opens up and boot even if i didnt press the power button.Anyone encounter this same problem?any help is appreciated

Since the phone boots without pressing the power button it must be a hardware problem but you could try putting it into forced upload mode by pressing the volume up, home button, and power button. Then try flashing a ROM.
Click thanks if I helped.

Try to enter recovery mode ( volume up + volume down + home button + power) and wipe data

remove the batt and leave your phone for 1-2 hours and then put it back again n see what happened..
try to get into recovery and wipe data/ cache / delvic-cache .. if its not worked then got to download mode and flash new rom...

It starts if you put the battery in? And won't stay in download mode? Maybe a faulty power button, constantly pressed? Maybe worth checking, opening up our G3 is really easy.

If none of these options work, take it in for repair

Force upload to flash
(Vol^ + home + power button)
(If it works then you are on the easier side)
Start the phone in force upload and then connect the usb through odin
Flash zero fill.tar
Wipe data, cache and dalvik
Reboot in download
Flash another rom.

It reboots after a few seconds in download mode. Would you try flashing in that situation? Serious hardbrick risk that.

You cant flash a rom if the phone isnt in download mode. Odin wont recognise it.
Press thanks if I helped.

'Download mode' (vol DOWN + home + power ) and 'Force Upload mode' (vol UP + home + power ) being two different modes have slightly different capacities.
Mostly when download mode doesn't work, the force upload does work in case of flashing ROM.

But it looks like a hardware problem so all he can do.is replace the power button

Apologies, I did not know that force upload mode even exists! You really got me there... what purpose has this mode?
I know it's OT, short comment or link will satisfy me^^

Having same problem. I already tried factory setting option also paperclip / hard boot option. not working any thing.
This happens while installing one of game (angry bird space) mobile complained with corrupted file and 2 times i tried. after that I try to switched off WIFI & JuiceDefender and then some applications complaining about not working. So I rebooted and then no screen comes at all.
Do I need to use update from SD from recovery option? or something else. I am afraid some thing badly happens and that's why my Micromax A100 superphone could not boot at all.

With the information provided, you may be in a bootloop. You need to boot to recovery.
1. Hold the power button to force power down the phone.
2. Quickly release the power button and IMMEDIATELY press the power button and both buttons in the volume rocker simultaneously.
3. Hold all three buttons down until your phone boots into recovery.
4. If it fails to boot into recovery and continues to normal boot, start over at step 1.
5. If you successfully boot into your recovery, do a full wipe (factory reset), flash Avatar, gapps, wipe cache, wipe Dalvik (under advanced).
6. Reboot.
See if this works! Good luck!

Yeah, you have a faulty power button. Common problem, replace it and your problems will be solved.

If you don't want to spend money to replace it, you can simply slam the power button on any hard surface for a maybe 5 seconds and it will be fine. I have to do this every couple of weeks/months. If you have gotten your button fixed already, how did you do it?

I've actually just been beating it off stuff till it works, I can't afford to replace it yet

[Q]

Hi all
my P6800 is acting up and I could use some help.
Not sure if something broke due to a fall or maybe it's a software/setting issue but here is what's going on:
- the power button seems to have taken the volume up functionality. sometimes it feel like it's doing both (i.e. volume up and power pressed together) because when I reset I sometimes get to the android recovery page (where you can reboot, update from storage, wipe everything, etc.)
- when I connect it to the charger it keeps going to the lock screen (i.e. I unlock it and after 2 seconds it goes back to the lock screen). it's working fine if I unplug it
Now, I figured I might as well wipe it clean and install the new JB (currently on ICS) but it's very hard to get to the download screen without a being able to hold the power button (for the power+volume down combo).
I did manage to get to it once (I was randomly rebooting while pushing different things) but I can't manage to do it again
so my questions for the pros out there are:
- Any idea how can I resolve the button functionality?
- Is there an alternative way to get to the download screen? I can live without the power buttom if it's a hardware malfunction but I want to at least do it with JB...
thanks

If you are rooted, try the app "RebootMenu" free from Google Pay
https://play.google.com/store/apps/details?id=org.riceknight.gs2reboot&hl=en
There are others too
Edit: If you are still unable to select anything in recovery (power button issue), instal TWRP recovery instead of CWM

I can select stuff in the recovery menu. pressing the power button goes one up and selects (which is consistent of it acting as both power and volume up)
Not rooted at the moment but might try it

worked.
Root, then used RebootMenu and now I'm running JB
Power button still acts as volume up but I guess I can live with it (and use Reboot menu to reboot every now and then)

Until OP replies, just a guess ....
1. Root from stock 3e recovery (Chainfire method) power button acting as both vol up+ power
http://forum.xda-developers.com/showthread.php?t=1849235
2. Installed reboot app
3. Booted into DL mode and flashed JB with Odin
4. re-root by same method (if root lost during flash)

Yeap, exactly.
Didn't do #4 yet though. I thought that method (without CWM recovery) didn't work for JB

Not sure about JB, but
With Mobile Odin Pro app you can flash firmware straight from your rooted device and option to retain root.
No need for DL mode

Is your phone a brand new device? Have you ever mounted a custom rom on it? Because on some new slc device (like mine) download mode is "factory locked" and you have to enable it with adb. Look around for the correct guide.

GT-P5110 unable to reboot directly to recovery after twrp installation

full stock, unrooted, GT-P5110
... connect to odin (3.12 PC)-> uncheck auto reboot -> install twrp -> PASS -> unplug cable from usb
but all I seem to be able to do is reboot into system.
I :-
hold power button for 1 sec, 2 secs, 3 sec.... trying to just turn it off (instead of reboot)
hold vol down + power button,
hold power button + tap volume down,
just hold vol down,
tap power button (does nothing), only long press restarts.
hold power button till screen goes black and then hold vol down + tap pwr button
hold power button till screen goes black and then hold vol down + hold pwr button
hold power button till screen goes black and then hold vol down on its own
search forum
pull hair out
type this
each time reinstalling twrp
any ideas what I'm doing wrong?

To reboot to recovery you need to hold volume UP + power.

well that's strange, as, on my device, from off:
Volume UP + power takes me to download mode... I have done this several times and it asks me to confirm by then pressing down.
AND, from off
Volume DOWN + power takes me to recovery.
and doing a search, via google and xda all agree with me.
.. but thanks
I never said I couldn't get into recovery... I cannot get from odin into recovery without it first rebooting and therefore wiping my flash.
edit: So I tried it anyway, and got back into download mode, which in a way is kinda good news as, my logic, if I can get back into download mode from a reboot then I should be able to get into recovery from a reboot.
Same same but slightly different

I am having the exact same problems and tried exactly the same things. I am just not able to install twrp because of this. ( I read that it overwrites the recovery with the stock one when you are not going straight into recovery mode after installation) I am stuck at the “Samsung Galaxy note 10.1” screen if try to go straight into recovery.
What is strange though is that with my device: VOLDown (towards the power button) + Power button takes me to download mode and the other combination supposedly to the recovery mode.
This is so frustrating. Done this so many times with other devices but this one just does not give up… I just want to get rid of all bloatware and other crap…..

I am currently doing just that! Using the files from autoroot . chainfire . eu (can not post links yet haha) . I will let you know how it went!
UPDATE:
It worked! I rooted my device first. After that I flashed my recovery via the TWRP app. I also must say that my device is the GT-N8010 (p4notewifixx). I got confused of all the different models. Still I think it will work with your model aswell! Good luck!
