TF shutdown by itself and then entered into boot loop.
There used to be CWM on it but the last ICS update broke it and there was no one around to fix neither CWM nor restore root.
Just half an hour ago, before I came to check forums here, TF responded to both volume + power up and power down buttons and I've seen both broken recovery and "wipe" screens.
Now Power Up doesn't do anything and Power Down goes into cold boot that subsequently loops after reaching unlock screen.
I see there's a nandroid back up in CWM folder on sd card created back in March as well as Titanium Backup folder dated April.
What are my options here? I have only a vague idea what Nvflash does so need a general outline before I start reading up on details.
cold-boot into android and reflash working CWM with one of the one-click tools in the general section, or use an Nvflash tool in the Development section to Nvflash rouge recovery, which will let you get back up and running. Don't use ROM manager.
Plugged TF into USB and suddenly got Power + Volume Down to boot into CWM recovery again instead of cold boot, from there got into wipe menu and now TF is back, waiting to sync all the apps now.
Thing O Doom, thanks for advice but cold boot was impossible - it went into boot loop immediately after reaching unlock screen.
I understand CWM changed original button configuration, Volume Down was supposed to be cold boot but with CWM it's recovery, and Volume Up that was original recovery now does nothing?
Is that correct?
Then broken CWM refused to enter into recovery but magically came back after connecting to the computer.
Odd, mabye you did the sequence differently, but it's good that it's working properly now.
I don't know how it works exactly, but I understand, using PC analogy, that CWM is like a separate partition and certain button configuration tries to boot the system from it, and it also has it's own boot menu where I could choose to proceed with CWM or go to the screen with the original "wipe" menu.
Right now booting CWM itself is not possible but its own boot menu is still there, it just leads to broken Android with a red exclamation mark (or to the "wipe", of course).
I don't think I want to keep CWM anymore, just root with Titanium Backup, so one more question - how to properly uninstall CWM?

When I load the bootloader with power and volume up and select recover it gives me the triangle picture with an exclamation mark in the middle. I am unlocked and rooted. I installed clockwork and can get to it from rom manager but not through recovery option. Help please!

i think this is covered in the FAQ, and it's definitely discussed in several threads already.
The triangle is the stock recovery. If you've updated to 2.3.1, the stock recovery is restored by a startup script every time you boot the phone. You can disable this by renaming the file /etc/install-recovery.sh. Then install clockwork again.
If you want to stay on stock recovery, to get into recovery, you do the vol up and power button, then from fastboot select recovery. Watch the screen closely when the phone reboots...for a second or two you'll see a box pouring an arrow onto an android. During that screen push power first (hold it) then push volume up. Timing is important.
I'm trying to flash the Vegan-Tab ROM on the gTablet I just got. I installed the 1.1 bootloader and CM .8. Or, I think I did. When I power up using power and volume +, I never got a menu when I tried installing these. The green box just popped up, so I assumed it was installing, then it rebooted normally. So when I try to boot into recovery mode, it does the same thing, and the menu never comes up. Did I do something wrong?
I have a similar problem ... loaded CM7 safely, was working for a while, all good. Decided (stupidly) to update recovery from CWM and now, nothing I do can get it to boot into recovery! Not manually, not through software (boot to recovery) options...
Also, the viewsonic birds screen is gone, so I assume something bad happened to the bootloader.
Still boots to 'production' cleanly, just not recovery or bootloader. Help!
FIXED - had to nvflash back to stock and start over!
hi all i have a T-mobile G2X and im trying to root this phone so... i try to flash CWM using NVFLASH and everything goes according to plan but once i try to boot into recovery by pressing both volume up and down buttons nothing happens. Once i flash stock recovery phone boots and everything is back to normal but once i flash either version same thing happens again. I tried searching but couldn't find a solution. So if anyone can help me or point me to the right direction i will appreciate it.
You boot into CWM recovery by holding power + volume down (do not touch volume up). Hold the keys a good 10 seconds and wait for the fancy LG logo. Once you see the fancy LG logo (not plain white) you can let the keys go. You will then boot into CWM. You are just pressing the wrong keys. Don't boot that way into stock recovery as it will do a factory reset on your phone.
I seem to be having the same problem, except that my phone only shows the s/w update screen and wont revert back to the stock recovery when i try. nvflash just leaves my phone on the update screen for hours. it will boot up normal if i pull the battery and put it back in, but it only shows the s/w update screen when i try to boot into recovery. any thoughts?
To boot into Clock Work Mod Recovery, you press and hold the "volume down key" and the "power/sleep" button at the same time.
Hold the buttons all the way through the Lg boot logo. After a short moment, you will see a distinct "purplish" bluish glow to the logo. At that time, release both buttons.
You will boot into Clock Work Mod Recover and ready for flashing
or use the Terminal:
$su
#reboot recovery

This command does not work on the P999. Recovery is not on the standard partition and this command will only reboot the phone. To reboot into recovery (if you have CWM installed on the physical recovery partition and not installed by ROM Manager) you need either Weapon Rom installed, which has this built in or there is an app on the Android Market written specifically for LG 2X/G2X devices that knows where the recovery is installed and can reboot into it. On some G2X (P999) models it says not compatible because of the way LG wrote the build.prop but instead of saying "Ok" which closes the program you simply use the back key to get to the main program screen and it works like a charm.
This app is also preinstalled as a system app on my roms.

Thank You everyone for ur help. Ive figure everything out and im now running MIUI ROM.
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.
I will try to give a decent amount of detail.
My G-tablet apparently ran out of battery, without me knowing. I tried to boot it up and it booted mostly in to android (enough for me to see battery at 0%) and then died.
I let it charge but next time I booted, though android loaded, none of my apps worked. I was also unable to boot in to recovery by holding the volume down button. As a last desperate attempt I went to Privacy - Wipe Data, which prompted the device to shut down.
When it started back up, I receive the message "Booting recovery kernel image", note WITHOUT holding the button (and without the recovery button held text).
From recovery I do a wipe of data partition and try to boot again. Same message, straight to recovery.
I say ok, I will flash the ROM again (vegantab), so I flash the ROM and reboot. Boot straight to recovery again.
One last try, I go to restore and try to restore a image from a few months ago. Restores successfully BUT, straight to recovery again.
No matter how I try to reboot, on the screen with the birds I get "booting recovery kernel image". It's like it isn't even TRYING to boot off the boot partition, and instead decides to load the recovery kernel no matter what I do.
So basically, I am now stuck in recovery and no amount of flashing / formatting can convince the thing to attempt a normal boot. Ideas?
edit: Fed up and in frustration I decided to format all partitions from recovery, including system and boot. After formatting the boot partition I now get the "Magic Value Mismatch" error message. Googling for solutions has returned around 95 different guides to fixing a gtablet, all with various completely different directions and outdated dead links to files. So if anyone has links to a MODERN guide to recovering through nvflash with files that actually exist, let me know.
Hey go to the gtablet for dummies website and download the nvflash 1.2 branch with clockworkmod. You do know how to nvflash right? Just press down your gtablet power button with volume - at the same time. That will put your gtablet in nvflash mode that is a black screen.
The nvflash you downloaded will have a folder with several files, if you are a windows user just put your tablet in nvflash mode and then Run the batch file located in the nvflash folder. Then wait for the process to finish and if the gtab doesnt reboots after everything is finished just reboot it by yourself
Remember you have to install windows drivers if your gtab is not being recognized.
