Boot Loop after attempted downgrade to HC

For the second time, I was attempting to downgrade from ICS to HC last night and ran into a bit of a problem. Here's what I have and did:
TF101 with 9.2.1.24 US 20120503
I rooted with PERI-0.4 (found here) and that worked fine. I then installed Super User and Recovery Installer. Started Super User, closed, then started Recovery Installer and clicked the button. It did its thing and rebooted. I had the zip of the latest released HC built on my microSD card and booted into the recovery console (Power + Volume Down). From there I wiped the cache and installed from the zip file. It did its thing for several minutes before saying done.
I then clicked reboot and instead of getting to the android guy with the green progress bar (like it did last time), I get to the revolver screen where it stays there for a few minutes and reboots..and repeats. I left it overnight and still doing it. I tried getting to the recovery console again to try and reinstall, but when I do that (power + volume down), The android logo comes up with a yellow triangle with an exclamation mark in him. It might also be worth it to add that I can't turn it off unless I hold the Power + Volume Up buttons. Holding the Power or the Power + Volume Down do not turn it off, it just reboots.
PLEASE does anyone know what I might be able to try?

can u cold boot from linux?

Thank to the wonderful people over at AndroidRoot.mobi and their custom NVFlash tool, along with using the latest stock ROMs, I was able to flash the stock rom and now have a full functional tablet again, AND as a double plus? Its at HC

Why did you use Recovery Installer after PERI though? What PERI does is install custom recovery xD

I did because when I tried to install the HC zip file in the recovery manager, It said it was unable to do so (something like directory doesnt exist IIRC) so ran Recovery Installer and then it was able to recover from the HC zip file....before crapping out on me.

Help!!!!! Phone won't boot

I flashed a zip, and now my phone won't boot! When I press power and volume down, it doesn't boot into recovery either! Like it vibrates twice but then just doesn't boot! Please help!!!!

I was also running cm10 liquidsmooth, and when I try to boot to recovery it just vibrates twice and the screen shows the samsung logo for like teo seconds. Then the screen just goes blank. I seriously need help!

Can you give a little more information, like how you went about the installation, your source for information and if your root worked properly the first time you did it on stock

It's the whole volume rocker (volume up and down) and the power button, to get into the recovery. Release the power button when it vibrates but keep holding the volumes until your in the recovery.
And make sure you do full wipes when switching roms, wipe data/factory reset, cache, dalvik-cache, and system. Or run Blackhole System Wipe.

When I hold on both volume buttons and press the power button and release it, it just flashes the samsung logo and the screen goes blank.
Basically everything has been working right before, everything was fine. The rom worked perfectly. After I flashed a zip (not a rom, it was just a camera app) I hit reboot in the cwm and then it just wouldn't boot, not into recovery either.

Try holding all of them for a minute or two. Sometimes it takes a bit. From what you have said nothing should have borked your cwm. If all else fails, there's always the option to use Odin to reflash back to stock or reflash cwm.

I always hold all three until the samsung logo appears, then I release the power button. When CWM comes up I release the volume buttons.
If you can still boot your ROM you should just use terminal emulator. (Download it from the play store if you don't have it on your rom). *requires root*
Type su
confirm root access.
then type "reboot recovery"
That should do it...
OR...
You could just ODIN CWM back on your phone if something got corrupted...

I used odin and followed the instructions.... but now the phone is stuck in a boot loop.

oh thank goodness, I flashed CWM through odin again and it worked. Thank you all.

[Q] Something went wrong while installing CWM and now CWM recovery mode wont open.

I was following this tutorial [wiki.cyanogenmod.org/w/Install_CM_for_p3100] form wiki.cyanogenmod.org and it went fine till step 12
#11. Unplug the USB cable from your device You can now manually reboot the phone into ClockworkMod Recovery mode by holding .
#12. The Galaxy Tab 2 7.0 (GSM) now has ClockworkMod Recovery installed. Continue to the next section.

And instead of starting in recovery mode, I started in normal mode mistakenly. So I did the whole again. Until now the "Custom binary download" was showing "2 counts" but again mistakenly started in normal mode. Then I did the whole once again, and held the power and volume up button to start in recovery mode. But the device was stuck at start screen (which shows galaxy tab 2 logo). I doesn't even start in normal mode. I did the whole again and again.
Now the "Custom binary download" is showing "5 counts". I somehow was able to start my device. But when I again go to recovery mode (using power + vol up button) I am getting the usual (the one provide my Samsung) recovery mode instead of CWM recovery mode.
I have few questions regarding this
Should I continue the tutorial now(but I am not getting the CWM recovery mode in)?
How to do nandroid backup, my tab is not rooted yet(checked using root checker)?
"Custom binary download" is showing "5 counts", will that cause problems? How to fix?
By the way, my device name is Samsung Galaxy Tab 2 7.0' (P3100).

Not able to install - always standard recovery menu

Hello guys.
Im struggeling to install a custom ROM at the stage of installing a CWM recovery. My S2 plus 9105p runs Android 4.2.2 and everytime I try to upload a recovery img via Odin everything works fine as expected but when I try to start (volume up, home, power) the recovery mode - it gets always into the standard Android one - not CWM recovery!!! It looks like Samsung has integrated some kind of security mechanism which keeps us from running custom ROMs...
I have realy tried maybe 5 different recovery images, but non of those worked for me.
Can you please help?
THX

I tried exactly also this particular site and steps described on it, but didn't help... The same problem. Everything was OK, but recovery was not CWM but standard Android one.

When u have flashed ur recorvery, take ur battery out and then plug battery again. And now go to recorvery.

Now it is WORKING !
Hi guys.
I followed the step-by-step guide on this page:
http://forum.xda-developers.com/showthread.php?t=2560928
- used the CWM 6.0.4.5 and Odin3 0.7
- after successfull flash of the PDA with this recovery (manualy unset the auto-reboot option) I have pulled the battery out for a couple of seconds
- the battery came back in again and with home-volUP-Power I got directly to the new CWM recovery.
So thanx all for your support and you can lock this thread as everything is working now.
DETAILED STEPS FOR INSTALLING CWM RECOVERY IF THE PHONE AUTOMATICALLY RE_FLASHES IT:
Installation
WITH ODIN
1. Be sure, that your device is on 4.2.2 stock firmware and shut down the phone
2. Be sure that Samsung drivers are installed on your pc. Just install Kies or google for them
3. Download Odin 3.07(google it) and the CWM-Recovery image (in this case CWM 6.0.4.5 )
4. Open Odin as administrator
5. Start-up the phone by pressing Vol_DOWN + Home + Power so you get into the flash-menu.
6. After reading the disclaimer and warning stuff - simply press Vol_UP and plug the USB cable to the PC and Phone
7. In ODIN click on PDA and select the downloaded CWM-recovery (*filename*.tar.md5) . Check - "F. Reset Time" and UNCHECK!! -> "Auto Reboot"
8. Click start and wait until the blue progress bar in your device is graphicaly 100% (I also suggest to wait another minute to make things sure..)
9. Pull out the battery
10. Pull out the uSB cable from PC and phone
11. Wait abou 10-15 seconds and power up your phone to get into the recovery menu by pressing: Vol_UP + Home + Power
12. DONE

Made it through Step 5, not sure what to do next

Howdy I have a older AT&T Galaxy Tab 2 10.1 GT-P5113 SGH-i497 Android 4.2.2
I followed the steps on forum thread Samsung Galaxy Tab 2 Development -->(ODIN + CWM 6 + ROOT + Stock) ATT / TMOBILE Galaxy Tab 2 10.1 {} {SGH-T779} by Childofthehorn
Well I made it through step 5, at least! (Odin displays green “Passed!”)
But the following steps:
6. Backup your existing image
7. Flash SuperSu from SDcard
8. WInning.
here's where I'm at:
(see attached)
strangely there is no button for attachment on the Editor Are attachments allowed on this forum? Peculiar!
Only choices on the Recovery screen are
reboot system now
apply update from ADB
apply update from external storage
wipe data/factory reset
wipe cache partition
apply update from cache
Don't know how to "back up your existing image"
or "Flash SuperSU from SDcard."
(but I do have the SuperSU apk on the SDcard though; do I select "apply update from external storage"?)
How do I know I have root? Odin said "Passed!" in green, but I'm not sure what that entails. -- I don't want to use any of those root checkers on Google Play because they all appear to ad-filled junk.*
Do I have CWM 6 by this process? How can I tell?
Is it possible to upgrade to KitKat? or is the P5113's processor not capable of it (or something else prevents having KitKat)
Not sure what I should do next.
Thanks everyone!

After Odin says Passed did you let the tab reboot to the ROM? If so the ROM probably replaced CWM with stock recovery (stock ROMs tend to do this), so what you need to do is flash the recovery again via Odin, but once it completes immediately reboot to recovery using the key combination, do not let the ROM boot. Once the recovery has loaded it should automatically disable the recovery replacement system in the ROM, and you'll be able to proceed to step 6.

Do you uncheck Auto Reboot and F. Reset Time? With those enabled all Odin said was Reset! in blue.
For the 3rd step:
Childofthehorn says:
3. Open Odin (as administrator) and hit the "PDA" button, remember to uncheck the reset
I assume he means F. Rest Time in the Odin options tab

Seems to reboot immediately after Odin finishes, happens too fast; there's no time to reboot into recovery mode with the power+vol.

Just follow what the instructions said, but uncheck Auto Reboot. Then, once Odin is done, force reboot the tab by holding both power and vol button down for about 10 secs (until it reboots), then release the power button while still holding the vol button.
