help resolving boot loop issue - Galaxy Tab 2 General

I put the latest version of CM10 and I got stuck in the boot loop sequence: I see only the intro animation.
1. If I press the power button for 7 seconds, the tablets restarts itself and I'm from where I went: the intro animation
2. If I press the power button for 7 seconds and the up button, the tablets restarts itself and I am in Odin mode here but do not have a pc only a mac with me.
2a) if I keep holding power button and the up button, I get in another loop: the tablet restart and I see the samsung logo and so on.
2b) if I take my finger off power button but I keep pressing the up button, the tablet gets into the intro animation of CM10.
Any suggestions in how could I resolve this problem?

I think you need to enter download mode then use heimdall for mac or linux to flash stock firmware

[Q] Help! Cant get my phone into recovery mode

Ive tried the volume down and volume and power but it wont work.... Any suggestions?
You are sure your phone is off and you:
Hold down the volume up and down with your left thumb and make sure there is a click feeling from both buttons and use your right hand to click on the power button?
I'm having the exact same problem. Have tried about 25 times to boot into recovery. Just does not work.
Pull the battery after every failed attempt took me about 2-3 tries. Before you do anything shut off phone pull battery then attempt to boot into recovery.
Yes, I'm doing that. The samsung screen comes up and if I release the buttons it does the normal boot up. If I keep holding the buttons the black screen with "vibrant" keeps coming on and off.
So far I discovered that it works perfectly if you hold the power button until after the Vibrant logo appears and then release the power button while still holding the both volume buttons. If you release the power button before the logo appears it will FAIL.
Only after the logo dissapears you can release the volume buttons.
In other words:
1-Press and hold both Volume buttons
2-Press and hold Power button
3-After Vibrant logo appears release Power button
4-Wait until Vibrant logo dissapears and then release Volume bottons
5-You should now be in recovery
Pito
Wow, I followed your directions step by step and still no luck! I wait till I the Vibrant logo to dissapear to release the volume buttons but it just boots up like normal. Thanks anyways! Is there another way of rooting my phone?
What I do as well is hold until the first logo dissapears and as soon as the second one appears release buttons. Then its in recovery.
Ive tried everything you all have said so far and I still cant get my phone into recovery mode. I was able to do it on my wife's vibrant but not on mine. Any suggestions?
Try getting quick boot from the market. It had an option to reboot into recovery. If your problem is just getting the button push right (i had real trouble with it at first) then this should work.

ROM: Stock
Recovery: Clockwork 2.5.0.4
If you are rooted then Clockwork Recovery Mod has the ability to boot into recovery mode. Or you can turn on usb debugging and use adb. Start>Run>cmd and use "adb reboot recovery"

Help needed.....Galaxy Tab always restart

Help......my Tab is having problem....it always restart....i cannot reset the factory data .Is that anyway to take out the battery to reset all data?anyone try b4???
Closed.................
how you resolve it?
can you share it?
i have same issue too
Start with your tab turned off. Then it's either, Hold Volume Up + Power Button at the same time or it's hold Volume Down + Power Button at the same time. One will boot you into fastboot, the other way will boot you into the stock recovery. You want recovery. You will know its right cause you will see an upside down triangle. Then hit i think it was search button or one of the volume buttons to get a menu to pop up. Highlight factory reset and hit the power button. If you boot into fastboot mode and not recovery, the screen will be black and will say please load OS or whatever. Just hold down power button to power off and try the other way.
Bear with me if directions are a little off. Gave my wife my tab months ago so I haven't had to do that in awhile

BOOT LOOP

is it possible to turn the phone off or start recovery mode without taking out the battery in case of a BOOT LOOP, sometimes it is not possible for me to take my phone out of the protective case and take the battery out if a boot loop happens
You can enter recovery mode using the "famous" 3-button press. But you cannot turn it off. A long press of the power button only reboots the phone.

Actually, if you long-press the 3 button combination while the phone is on, it will boot into recovery (or download) just fine.
EDIT: Just keep them held down until it reboots. It takes ~10 seconds.
Download quickboot from the market.

Could you please enlighten me: situation from the post 1 is: BOOT LOOP.
your advice is: go into the Market, and then download Quick Boot.
Brilliant, I think, I'd only would like to have explanation, on which stage of the BOOT LOOP are you suggesting the Market opening, download, install and run Quick Boot?

No need to be a clever twat. Never had soft/infrequent reboots?
Take your **** comments elsewhere.

wolf your advice was not wise so shush
no app will help you enter download/cwm while your phone will bootloop
you can press and hold power that will restart phone but in case of bootloop that does not help
you can press volume down+menu+power and hold untill you will see yellow download triangle'
you can press volume up+menu+power and hold untill you will see cwm recovery starting
that combination does nothing unfortunately. x10 mini.
care to post on proper forum for your phone ??
Actually I have found that if the phone is boot looping you don't even need to press the power button. Most the the time you can just press home and vol up or down to get recovery/download mode (or both to get recovery on bell kg3) when the phone does it's next boot. My theory is that the power button isn't part of the button combo per se, you just need it to turn on the phone if it is off.
Of course you can always hit the power button anyways if that doesn't work. The power button held should make the phone reboot in about 10s no matter what, with or without a recovery/download mode combo.

If you are getting a boot loop, but can't get into download mode (no matter what combo you're pressing) you're still OK.
What you need is the "jig". Either make one, or pickup a cheap "download mode jig" off of eBay.
As long as you can see the boot screen, the jig can still get you into dl mode...

Stuck on Google logo boot screen -- Bricked??

I unlocked the bootloader and flashed a custom recovery. I then rebooted the device. Now it is stuck at the bootloader (white Google logo on black background) and I can't get it to do anything else. I've rebooted it a bunch of times including with the vol + and vol - buttons held down to no avail. I've also let the battery run out and then tried to boot it up again and the same thing happens. adb nor fastboot see the device and it doesn't show up in the logs on my machine (Mint 13) as coming online at any time.
Most of the times I reboot it with the power switch it reboots to the Google logo even without me letting go of the power button. Sometimes I can get it to fully power off but I haven't figured out what combination of vol keys and reboot does that.
Anyone have any ideas what could be wrong? Any help would be much appreciated!
You are not bricked if you can still get into the bootloader.
Download the factory image from here, and flash it with fastboot. If you don't know how to do that, read this thread.
I wish I could get fastboot to see it then I could definitively flash that img.
I can't get into the bootloader and can't get fastboot or adb to see it. It's stuck at the Google logo now and when i hold the power key it reboots back to the Google logo with the unlock logo at the bottom.
Thanks for the help
You've tried holding volume down+power for 10+ seconds? That should power off the device, then hold both vol up+down down and power up
Ya I've tried to hold vol + and power for 10+ seconds and it reboots back to the Google logo even if I don't off the power key. Same happens with all the other combinations of keys being held with the power button. I can't get it to turn off now unless I let the battery die
Press and hold power till screen goes black. Then quickly press power+volume down and HOLD.

Tried that and still stuck at the Google logo. I have to go to work for a couple hours and then will hack on it when I'm back. Hope I don't have to deal with Googles rma process seeing how disorganized the rest of that company is

No luck with any button combos but the vol + and power actually turned it off. All out of ideas over here. I'm thinking it really is bricked
I'm in the same spot. I can get it into recovery occasionally but once there it locks up after trying to flash or clear the cache.
I'm wondering if a contributing issue is CMR v6.0.0.6? I updated it from 6.0.0.4 that was running fine. But no fastboot or adb so that is doubtful.
This is frustrating and not a great start with this N7.
thank you

this worked. you have to be fast. as soon as screen goes black release power button then quickly, very quickly repress along with vol up and down.
You will still be able to get into the bootloader! Force kill the tablet by holding the power button for ages. Then hold volume up and volume down and the power button together, which will boot to fastboot.
It looks like a CWM bug as I feared. Anyone in the same boat try here - http://forum.xda-developers.com/showthread.php?t=1782932
Nothing has worked and I've literally tried everything that those three buttons can do. Thanks again for all the help guys. Had a great time trying to resurrect it but guess it's time for it to go back home
Just as I suspected. Google puts out buggy junk once again.
I just wanted to report a similarly event. I have a rooted, unlocked Nexus 7, with TWRP recovery. I have previously rebooted without issue. Tonight I booted into bootloader mode to check something and the hit power button to choose start. I got stuck on the boot logo. After finding this thread, I started with the simplest combination and held power button until screen went dark, then added volume down and once again in bootloader. This time choosing start led to a regular system boot. It's as if the device froze and needed a hard reboot.

I was attempting to boot into recovery and kept getting the 'Google' logo (I am unlocked/rooted with twrp recovery). I wasn't aware that one had to be plugged in via usb in order to *not* hang....
Any way around this?
Once I plugged it in and attempted to boot into recovery it worked fine.
I had a similar issue after using the Nexus Root Toolkit to flash to nakasi 4.2 with CWM recovery - just got stuck on the nexus boot screen, flashing in a loop for over 15 minutes.
I ended up powering down the device, holding power for about 5-10 seconds - then QUICKLY holding both the power and volume up+down keys, it then went into the fastboot screen.
After it was there, plugged it into my PC.
Now, this should work for you - assuming you have all the fastboot/usb driver stuff installed.
I extracted the contents of nakasi-jop40c-factory-6aabb391.tgz into the same directory as the fastboot.exe provided by WugFresh with his Nexus Root Toolkit (google search or xda search for this if you dont have it, i dont think i can post links due to my low postcount) - typical filepath: C:\Program Files (x86)\WugFresh Development\data
By the files in there, I mean drilling down inside the tgz to where the image files were inside so that files like bootloader-grouper-4.13.img, image-nakasi-jop40c.zip etc were extracted into the directory and sitting alongside the fastboot.exe - NOT in a subfolder.
Once its all here, running flash-all.bat (this is provided by google in the nakasi-jop40c-factory-6aabb391.tgz) from the command line or by double clicking on it from explorer should kick off the process. After about 2-3 minutes, it was complete, and my Nexus then booted up within about 3 minutes after that.
Also worth noting, device remained unlocked, but I lost root/root binary

[Q] Samsung XCover 2 GT-S7710 bootloop

Hi,
I have a Samsung XCover 2 (or GT-S7710) that is stuck in a boot loop. The phone has never been flashed or rooted.
I couldn't get the Samsung logo shown, just a not-spinning spinner.
Image I have : andre-k.at/img/image1.jpeg
Taken from thread : forum.xda-developers.com/android/help/gt-s7710-samsung-bootloop-t3015707
When I try to enter in recovery mode (vol up, home, power) nothing happens.
When I try to enter in download mode, I have download mode shown a few seconds, then reboot...
I tried to flash a stock rom with odin and download mode, but flashing was interrupted by a loop, and now I have "Firmware upgrade encountered an issue. Please select recovery mode in Kies & try again." shown a few seconds, and then reboot...
Any idea on how to get my phone working ?
Thanks
HI,
the real reason is maybe that the phone isnt charging
To fix it hold on charger after 1st shut down hold power volume down and home button. When you enter download mobe click on volume down button very fast before it turns off. It wll restart to fastboot ( samsung galaxy xcover 2 and model showed. It will shut down after it. So when you click on restart after 1 sec hold the volume up and home button. the power button will automaticly trigger and then when it showes the logo 1st time wait when the screen is black wait and when logo shows again release the buttons. then wait you whil enter recovery and dont do anything just let it charge it wont restart in this mode for some reason
reply me if you did it or there is an error
I actually have the same problem, but when I reboot it in fastboot and I press the volume up + home button, it displays the loading screen and it just doesn't work.
Am I doing it wrong ?
