I tried to install the ROM. but every time I press and hold Volume+ and Power, it shows "Detect a recovery key pressed" and "Booting Restore Kernel image", then gTab shuts itself immediately. Also, tried the Factory Data Reset, rebooted to the birds and turned itself off again.
The device is not bricked, but I just can't load any ROM.
Please help.

use the microsd CWM install and see if it works. If it does, you'll see the box with install progress bar. If not, then NVFLASH...

Thank you very much, it works!
To install the utility ClockworkMod is the key.

I broke my phone, now it's back. I rooted it, installed CWM again, and I'm running into trouble. When I try to boot into recovery through Rom Manager, it asks if I'm sure I want to, I hit ok, and it doesn't do anything.

Try a hard reset into recovery. See if that works.
Launch stock recovery, go to install update.zip and hit the home button. Should get you to clockwork.

How do I do the hard reset? Sorry, I'm new to the phone.
Shut your phone off. Hold volume up, down, and the screen on/off button at the same time until the "samsung" comes up on the screen. From there your phone will boot into the stock recovery. Use your volume up/down buttons to navigate the menu, scroll to install "update.zip" then select if by pushing the home button. From there you should boot into clockwork.

It starts installing, then says
E:failed to verify whole-file signature
E:signature verification failed
Installation aborted.
Sounds like you might have deleted the update.zip file that is needed to launch CW from your SD card.
Go back to this post to either start from the beginning or to just download the file and put it back on your sd card:

I followed the instruction for installing the clockworkmod on viewsonic gtablet. I placed the update.zip and the recovery folder in the internal storage. I reboot the tablet (power and volume+)
The box with the down arrow appeared, and then I pressed apply update.zip, and then nothing happered for a long time. So I reboot it and tried to do the same steps again. BUT now it stuck when I reboot it at "Booting recovery kernel image"
so what shall I do?????
Depends...
1) Does it always reboot to "Booting recovery image..." or only when you're holding the volume up key? If not... can it boot normally?
2) What ROM are you running?
Two times now, once before, and once after flashing a new rom, I have been stuck in a recovery boot loop when I select "reboot recovery" from the advanced menu in CWM.
When I "reboot system now" the tablet magically goes back into CWM recovery. Without any keys being held, I see the message "Booting recovery kernal image" on the Viewsonic Birds screen.
Is "Reboot Recovery" a fatally flawed menu option in CWM?
More importantly, can I recover the tablet short of an NVflash (which is how I recovered the first time)?
I've tried holding down power+volumeup. I have run a keytest as well, all keys work. I feel like there must be a simple way to stop the tablet from rebooting into recovery? WTHelp?
Same issue here. Anyone have a solution?
You can go back into the CWM recovery menu and try to "Fix permission", if that doesn't work, "Clear Cache/User Data", if that stilll do not work?
Repartition 2048/0 and then mount USB, load the ROM and reboot
simpler?
I have the clockwork mod recovery loop. Going from 4349 to Flashback. None of the above mentioned suggestions have worked. I am not ready to try NVFlash yet as I >think< that SD card issues could really screw the Gtab if I might have one of "those" sd cards installed.. The ROM loads just fine, but reboot system just goes back into CWM recovery.
Help!
Try erasing the "misc" partitition (or the "bootbmp" partition as need be) as described here.
Do the same for the "cache" partition.
This has happened to me twice, I just nvflashed and it worked perfectly again. This is probably the only sure way you can get your tablet to boot to android again.
Interesting. I have not seen this problem, however I seem to have the opposite! Selecting "Reboot Recovery" either from Quickboot or the system shutdown menu (when I press the power button), just reboots normally. It will not boot into recovery. The only way I am able to get into clockwork anymore is to do a reboot and hold down the volume+ key. Everything else works normally though. I wonder if there will be any updates to CWM. Do you think this is a bug in CWM or something flakey going on w/ the G-Tab?

After you select "Reboot Recovery" does the first splash screen--the ViewSonic birds--disappear?
I need help trying to figure out why my phone will not factory reset. I unlocked the bootloader and installed stock gingerbread a few months ago. I was planning on selling the phone to a friend of mine, so i needed to factory reset. Any time I would try to factory reset it, the exclamation mark would come up after it restarts.
I tried factory resetting with a new rom, but all my apps and my motoblur account would remain after loading the new rom. the last thing I tried was the Stock ATT 2.3.4 SBF.
After using SBF if booted fine until the lock screen came up with no initial startup guide. and it keeps telling me that " The application LauncherPro (process.android.process.acore) has stopped unexpectedly. Please try again" when I press force close, it just pops up again, giving me no time to access the home screen, let alone the menu.
if anyone can help me access and get rid of this program from outside Android, it would be a great help, thanks!
fastboot -w
Im sorry but please bear with me. i also need help setting up ADB for the atrix in order to do it. for some reason I can't access my phone.
There are be a couple of ways to do a factory reset.
1. Using the fastboot (maybe it was moto-fastboot), you can put the phone in fastboot mode. Phone off, press and hold down volume key then press the power button. When the screen says "Fastboot", press the volume up key. Then as mentioned above, do "fastboot -w reboot." This will erase user data and cache then reboot the phone.
2. If you have one of the CWM recovery images installed, do as above, but when "Fastboot" is displayed, press the down volume key until "Android Recover" is displayed. Now press the volume up key. In a few seconds, the recovery menu will be displayed. Select "Wipe data/factory reset".
3. With the phone fully booted, Settings->Privacy->Factory Data Reset
Good luck
yeah my problem now is accessing my phone with adb. it wont find fastboot. saying that fastboot is not recognized as an internal or external command, operable program or batch file. Is there some kind of package here I can use/find?
Edit: Got it working! thank you guys for the help!!!!
I'm a bit stuck here, would appreciate some assistance.
I tried to root my device (UMI Plus) by yesterday using 'SP Flash tool' by flashing TWRP and then installing SuperSU. That went fine, but after booting my Google Play Services kept rebooting rendering the device unusable. In an attempt to fix this I tried a "Factory Reset" via the Android settings menu which I guess was a bad idea because it started auto booting into Recovery... At that point no matter what I did I ended up back in Recovery.. Reboot to system, factory data reset.. all rebooted the phone back into TWRP recovery.
So I thought I would just try putting the default recovery back on the device again but whenever I power off the device and connect it to my PC it boots into recovery.. The phone needs to be powered off for SP Flash Tools to work. Tried loading recovery image via fastboot but the volume rockers don't work in fastboot so I can't confirm the action.
After some digging I read online that holding down VolUp + Power can 'force' into preload mode, which seems to have some success. I can see the device boot into "Preloader mode" in device manager in Windows, but it loses connection after about 3 seconds. So I did that with my SP flash tool ready and it seems to have erased recovery mode. Oops! Now whenever I try to get into recovery it just says "No command". No combination of button pressing, button holding, button releasing or anything will change this (This is the only answer I could find on Google!). Neither fastboot or adb can see the device either. It shows up as "MTP USB device" in device manager in Windows...
Is it doomed? I can't figure out what to do next...
P.S. The full ROM is available here but in RAR format.. which seems strange to me...
