If you did everything according to the guide it should be fine.
Try plugging the phone into the charger before holding home,power, vol +. Sometimes the combo is a bit stubborn and won't work without being plugged in or on the first few tries.
I've done it unplugged and plugged in probably 30x each out of frustration. No dice x-(

Make sure you release the power button IMMEDIATELY when the phone vibrates and keep holding the Home and Vol + buttons until it boots into recovery. When I have had it go blank and reboot it has almost always been because I held down the power button too long. However, as stated above you have to sometimes plug in the phone if the battery isn't close to 100% charged. The only other thing I can think of to try is to pull the battery for about 10 secs or so and then put it back in and try again.
Wasn't releasing the power button thanks! Never ran into that before... Hmm

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.
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 -__-
I haven't seen anything that quite fits my situation, I unlocked my tablet, and rooted it, and installed CWM. I then went to install CM nightly and upon reboot the tablet froze at the ASUS boot screen, I've tried rebooting by holding the power button down, holding the power and volume down button down, and power and volume up, with no luck. I've also tried letting the battery die and then booting back up with no luck. Could anyone provide any assistance?
Thanks.
Now when you say it froze, you mean you let it sit there for awhile right? You gotta give ROM's time to create a cache! Try using fastboot to boot into recovery and install stock just to make sure it works

Cwm has issues on this unit, I suggest twrp when you get to that point.
To recover your unit you have to be able to use adb, fastboot, or recovery.
Here is a link to help you get into position to use one of those.
Good Luck!
Note: If you get into the bootloader menu do not use WIPE DATA!
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!
Edit: PROBLEM SOLVED! However I'll keep this up just in case anyone runs into a similar issue, I'll go ahead and quote the post that brought my tablet to life. As simple as it may be, it helped!

You can't really hold them together sometimes, I don't know why.
Hold volume down, press power and release, while holding volume down. Should go into bootloader then.

Okay, so in case I'm missing something, I'll keep it quick and say my tablet (WiFI version) wont boot to the system, and no button combo will boot it into the bootloader. It goes straight to the nvidia screen no matter what, and won't get past the boot animation.
In case that doesn't cover it, and more info is needed, I'll give the complete rundown of all that happened.
I just got my tablet a few days ago, however I immedietly unlocked the bootloader, and rooted it, and was fine with that for a while. Eventually I got sick of Lollipop due to lack of support for some Xposed modules and other apps that didn't support 5.0. So I decided to boot into recovery and flash THIS CarbonROM. But it didn't boot past the CarbonROM logo, so I forced a shutdown and booted into recovery (vol down + power) and figured I had to flash the KitKat OTA, then the ROM. So I flashed THIS OTA onto my tablet in CWM, then after booting I booted back into CWM and flashed CarbonROM. It booted just fine. I then went into ES File Explorer and deleted the system apps I didn't want (calender, the stock launcher, etc.) and it worked fine. I then booted back into CWM to clear cache and Dalvik Cache, to clean up any app data that might have been left behind. After booting it stayed on the "Android is upgrading" screen for almost 20 minutes. So I decided to hard reboot it. After doing that, I'm where I am now. The tablet won't boot past the CarbonROM logo, and although I can manually power it down, no matter what I do, I can't boot it into bootloader. I have gotten to the bootloader from a powered off state plenty of times before, in fact it's my preferred method of doing so. But now it skips straight to the Nvidia screen, followed by the CarbonROM screen, and never boots.
Also, I had just flashed the ROM, and had never enabled adb debugging.
Any possible solution would be greatly appreciated, as like I said I just bought the tablet days ago.
Try connecting it to your pc, boot it up, and try running "adb reboot revovery" after it's been running for a bit

I seem to get a "error: device offline" message when I try that.
I have used adb and fastboot before this issue so I know my drivers and adb files are just fine :/
Edit: When I unplug the usb from the tablet it makes the low battery noise. I think it's booted to the system but stuck at the CarbonROM logo for some reason. I did delete the stock launcher without installing a new one...
Edit: Since I had just flashed the ROM, I had not yet gone into developer options and enabled adb debugging. I had only done it before I flashed the ROM.
