i have a Galaxy Tab 2 7.0 p3113.
i used heimdall to flash CWM into the tablet.
after what seemed like a succesful flash, my tablet rebooted. but for some reason, it would only go as far as showing the galaxy tab logo. it seems stuck there. i could not turn the unit off. i would hold the power button to force shutdown, but it always starts right back up. it seemed like i could only shut it down if it was connected to my mac while holding down the power button. i can however, boot into download mode.
after consulting google, it seems like the appropriate step was to restore the unit to stock. problem is, i can't seem to boot into recovery. i'm being told by the internet that to boot into recovery, i need to hold [power] and [volume down] until it turns on and then release [power] but keep on holding [volume down] and CWM will load. but nothing happens.
i know this is a total noob post, but i've been scouring the web for two days. i'm at my wits end. any help would be greatly appreciated.
I think recovery mode accessed via volume up+power if you could not so use download mode to flash stock or so to return to normal operation

I press the power and UP ( button next to the power button) I normally hold BOTH buttons down at once and let the boot cycle process twice just to make sure i am going into recovery .....so i see the white samsung text twice i mean. It may take around 10 seconds to complete the process. Then release BOTH keys at once.
The battery needs a good charge for it to work.. Try charging over night before you try it via the mains supply.
Holding the power button and down will bring you into download mode and thats what you use for an odin/heimdall flash.
Hope that works for you
Let us know how you get on .....
Thanks. The battery of the gtab2 drained overnight, so i've got it charging back up now. Will definitely post my results when i have something.
Thank you guys. I'm able to boot into recovery now.
But unfortunately, i still need a little guidance on my original problem. And that problem being that my gtab2 will not startup. After rebooting, it gets stuck on the logo screen. It also plays a startup audio clip. But after that, it just displays the startup logo screen. It does not go into the animation screen and start.
I should also mention that when i plug my gtab2 into my computer, no drives show up.
My question now is, if i were to select [wipe data/factory reset] in CWM, would this restore my gtab2 to it's original factory state? Or would I need to flash a ROM for this? And if i need to flash a ROM, could i place a ROM on a microsd card and flash from there?
*********UPDATE*************
Everything is fine (so far).
I went poking around CWM and realized that I had put a cyanogenmod 9 update.zip in the root of the internal sd card before all this happened. So i went back to cyanogenmods wiki on how to install it on my gtab2 and followed the rest of the instructions on flashing it and VOILA!! I have my gtab2 back.
you should use ODIN instead CWM.
CWM is not designed specifically for Gtab2.

My phone is currently sitting with a "S/W upgrade" screen after a series of stupid events. I flashed recovery using ROM Manager before I had read that it fake flashed. I rebooted into recovery and installed CM7 nightly. Rebooted and it's stuck in a boot loop. So I finally see all the warnings against that so I figure I need to get a real recovery so I use the awesome guide from TGA_Gunnman. I follow all the instructions and it appears from the log on my PC that the CM recovery flashed successfully. I pull the cord, reinsert my battery and my phone just sits in the S/W upgrade screen. It's been like that for 30 minutes now.
What do I do?
I thought I'd done something wrong with my G2x because that happened to me too. Remove your battery and USB. Then insert your battery again. When you turn it on, make sure to hold both the power button and the volume down button until you see text that says android. If you, like me, thought you just had to hold the volume down and tap the power button (like my Nexus One), that might be your issue.

just disconnect usb, and go to recovery Power+vol down...
.....and congrats !
yep, I thought I bricked it too.. When you were done at the green screen where it said press any button, thats where you press whatever you want and then unplug the cord. Then, put the battery back in and hold down vol then power, don't let go until "android" pops up.. You did it man, just missing your last step..
Moved to proper forum
I can get to the Recovery screen, but I cant select any of the options....volume lets me scroll, but cant find anything to select any of the options....kinda new at this
power button to 'action' your selection... at least it works for me.

The "S/W upgrade" stays on, that's normal. See if your terminal window has completed whatever stuff it is doing. If you get a completed message, you are good to go and can safely pull out the USB chord even if your phone still says "S/W upgrade". Put back your battery and hold Power+Vol DOWN button and see if you get into cmw recovery.
so im trying to fix my friends phone and this is weird..
im able to go to cwm, wipe it all and flash a new rom.. it flashess successfully but when i reboot it goes back to the s/w update screen..it happens with any rom i flash.. its been sitting there for a while.. how long should i wait?
Once you flash the ROM you shouldn't be getting that screen...Does your friend has the G2x or 2x and which ROM did you flash?
Sounds like you screwed up the boot image. Go into APX mode again and reflash the recovery package making sure it completes, you hit a key to close the terminal window, and you hold the volume buttons the entire time. Then go into recovery and factory reset and clear the Dalvik cache. Then if you still get the S/W update screen you are going to need to go to the thread about fixing bricked phones and use the KDZ method to reflash the entire GB OTA package. There is also a new method to reinstall the entire OTA package using NVFlash but you have to hold the volume buttons down for about ten to fifteen minutes while everything flashes.
Ok so today my triumph stopped responding so i restarted it (took out the battery). then rebooted. upon reboot phone shuts down and now will hang at the motorola logo for about 10 min before boots but will shut back down due to the battery being dead(but had full charge when this started). Dont know what happened. So i try to get into clockworkmod to flash backup. cant get into it. the only thing i can do is get to the recovery.img file(pressing power+volume down). Other than that nothing.
also tried to boot with power pluged in. it stayed on but would not respond to any touches or button press except the lock button.
I have cwm 5.0.2.6 installed and tickerguy's cm7.
never had this problem till today. Any help would be appreciated.
a new development has occurred. now when i try to access recovery, the phone will just vibrate without stopping.
and i believe its stuck in a boot loop but without recovery i dont know anyway to exit the loop.
Are you able to get into download mode (power off then simultaneously press power button & vol- (should show polling))

Yes i am able to get to download mode
Well after some tinkering (replacing the recovery image, assuming something corrupted it) i can now get to recovery, still takes 10 min to load it though. But i am unable to do anything in recovery because i have to press the menu button to confirm selection but the buttons wont respond. Some help would be appreciated.
Ok. I bought this Galaxy Tab 2 7.0 from a friend for cheap because I thought I could fix it, but I'm running out of options. It's in a boot loop, but an abnormal boot loop. If it's unplugged, It will do the splash screen (Samsung) boot loop. If it's plugged in, either into the wall or into my computer via usb, it will do a battery (charging) boot loop. It's kinda weird. I used to have an Epic 4G and it happened damn near all the time, without the battery loop, but it would charge normally.
I haven't successfully gotten it to boot into Download mode.
If any of you have come across this issue, please feel free to help me out.
I also attached a picture of me attempting to put it in download mode. It reboots if I hit either VOL up or VOL down.
Thanks

Can you get into recovery? Also, have you tried unplugging the charging cable and getting into download mode with the cable unplugged?
I'm not sure how to get into recovery. With it unplugged, all I have to do hold the VOL Down physical button and ti will take me to a "are you sure you want to put the device into download mode screen". I apologize. I'm not to familiar with this device.
Edit: After I get to the screen where it asks me if i want to go into download mode, it reboots within 5-10 seconds, no matter which button I press

Hold power and Volume up (volume button closest to the power button) until the tab shuts off and reboots itself and then you can let go of both buttons. If it works, try doing a factory reset. Was this tablet rooted (or have a custom rom installed) in the past?

As far as I know it's been on Stock. My GTab ignores me holding the Power and Volume up keys at the same time and keeps the boot loop going strong.

Then I guess you can (and need) to send it in for warranty service (or replacement).

No, his device is fine.
If your device bricked, but still showing Gtab2 logo on it, it's still fine. You need to flash to stock 4.03 rom via ODIN. (Not clockworkmod)
Warranty won't work if you have flashed custom ROM before.

He needs to be able to get into Download Mode to use Odin. He stated that he can't. When he tried to continue into download mode by pressing volume up (vol. button closes to power button) the tablet reboots. It needs warranty service.
Experiments:
Power off the tab completely and charge completely and press power +volume up for 10 seconds then release, also try to power off and press power+ volume down for 10 seconds then release do you see any screens
If it says do you want to enter download mode or so press volume up and see if you could see (downloading) try also the same with volume down instead of up
Try to connect to computer do you see any messages indicating connections
Also try to connect to kies and try restore or recover firmware from options of kies
You said it reboots after 5 to 10 seconds so try to open odin and try to go to download mode and when you press volume up try as quickly as possible to connect tab to pc while odin is open

There's other method by using OpenRecovery (OR), by putting OR on external SdCard,
but it seems the OR for Gtab2 is not developed yet -__-
So, been running CM10 for a long time on tab. Decided to go back to stock, and downloaded the JB stock rom. Flashed via ODIN. Everything seemed to go OK, except that after the flash the screen went black for ages, and didn't reboot. So I hard powered it off. Probably what did it, but it wasn't going anywhere for about 15 minutes, so figured it was the next step.
Now, I get the battery charging icon. The system goes through the Galaxy Tab 2 7.0 white logo, the swirling then glowing Samsung logo, and then loops through that forever.
It wouldn't be such a problem if I could back into ODIN and do another flash, but I can't get into download mode (normally I do it via adb but that isn't working since there is no USB connection at all). Tried all combinations, power/up, power/down etc. It just boot loops as above. I'm pretty sure I bricked it, but just wanted some confirmation.
Been doing this on and off for a long time, and it's the first time I've ever got stuck like this.
Thanks in advance.
Plug USB charger, your device will boot into charge mode. From charge mode you can boot into recovery by keep holding VOLUME UP button and than press POWER button. Clear data and cache in recovery, reboot.

Thanks, but I tried all combinations of Power/Volume UP and Power/Volume DOWN, it just goes through a normal boot cycle until it starts looping.
I guess it's possible I'm not using the right timing. I'm assuming that you hold Volume UP or DOWN and then press and hold Power until the screen goes black, and then release? I've done it like that many times, and also continued to hold everything down as the logo appears, and then system goes back to the battery charging icon as if it powers off again. I sound like such a noob when I type stuff like that!
I saw ODIN successfully write system.img, boot.img, and recovery.img, so I'm thinking any CWM recovery I had on there is toast.

You must pull usb cable before start.
You can try to re-flash.

Well, don't I feel like the idiot!
How did I not think to disconnect the USB before trying this? tuxafgmur, your first "Thanks" has been registered, I've got it from here!
P.S. Welcome to the forum!
it sounds strange. never heard of such a strange boot problem. anyway it could be that while transferring boot.img it became damaged due to some error. i know you probably tryed but you may try and connect it to linux or mac os x in order to check if you could retrive more data about the tab. for example the mac could find if it is totally corrupted. normally when i plug my samsung devices it ask me to add the samsung-modem also if they are turned off. meybe if it happens the same to you you can try to adb fastboot it also if i doubt myself about it working, but give it a shot
i hope my bad english is not preventing you to understand what i'm saying!
give us new feedback!
Sorry for the long title but it states my predicament. Basically my power button is done and I can't boot into recovery anymore. It just is a endless cycle of reboots(vibrates everyone 15 seconds or so). I even tried to enter download mode, which it does but than restarts the bootloop issue. Anyhow, I've never used ODIN so someone please fill me in. I want to ODIN back to stock because it's my last hope and basically I can't get into recovery anymore anyway. But do I need to use my power button to ODIN? Also what if I can't get into ODIN mode because it just wants to continue to reboot. Any help? I'm at a lost here.
Oops, wrong section. Mods can you please move to Q&A...sorrrry.

Moved to Q and A. I suggest pulling your battery for at least thirty minutes or maybe an hour. Then put the battery back in(do not power on) and plug the phone into your charger and allow it to charge overnight. From what you have said the power button does indeed work but you have done something to your phone causing a boot loop. In the morning search XDA for Odin procedures (there are a plethora of them on XDA) and attempt your Odin to stock. If the phone continues to boot loop I hope you have insurance... I did this to my LG Optimus once... And couldn't save it...

It does "work" but not correctly. Apparency its a known issue and called SDS. basically the way it acts is that when I press the button, the phone
Is acting as if I pressed it twice. So I press it to turn screen off, screen comes right back on. Long press power button for reboot menu, flashes, dissapears and than comes right back. This I believe is why I can't boot into recovery or download mode. Not that the phones bricked, but the phone is having trouble recognizing power button hits.
So my last try was to Odin back to stock just to see if that helps. But when I hold the buttons down to get into download mode or select it in reboot menu, it boots into it real quick(I see download mode appear on screen) but than immediately starts looping. So when I use Odin, will it automatically boot into download mode for me? What about mobile Odin?

I had the same problem With my s3... It was out of warranty so I sent it to mobile tech videos to have the power switch repaired. It's been great ever since. I realize that doesn't really Answer your question about Odin, just figured I'd chime in with what I had to do. I was afraid to attempt to Odin or flash anything before the repair bc in my mind the phone believed the power button was being pressed repeatedly and that would make it interrupt the flash.
Also if you're under warranty, Samsung will most likely fix it despite being rooted. Mobile Tech Videos sounds like a great option too if you're out of warranty, glad to see there's an alternative way to get it fixed.

I don't have the phone in question but for my Samsung Vibrant (Galaxy S, T-mo variant) if you press and hold the Volume Up button while plugging in the charger or say your computer's USB port the phone will boot into download mode. Not sure if it will work for the S3 though. Hopefully it does! :fingers-crossed:
Also, for my work around, I've mapped the Volume up button within ROMs to 'POWER WAKE' to replace the power button. It's not needed but its an easy way to reboot to recovery if its implemented in the Roms power menu. Occasionally the phone will crash or the battery may die. If I'm at home, that's an easy fix, just boot up download mode and flash a kernel/modem/recovery via odin and make sure auto reboot is selected. The phone should boot, granted there are no errors. The only problem I have is when it crashes or battery dies and I'm not at home I can't turn on the phone. If anyone knows a way around powering on or booting into recovery without the use of the power button or odin/download mode I will be eternally grateful. I'm try to get my Vibrant in working order for my father whose never had a Smart phone. I myself have upgraded to the s4 and am glad I stuck with what I knew instead of getting the HTC One. =]

Read this thread. Power button issues on S2 might help and save you time and money. Or if you want to get into download mode use adb.. "adb reboot download " or can be done in terminal.
