[Q] {HELP NEEDED} Completely bricked! - G Tablet Q&A, Help & Troubleshooting

I was previously running TntLite v4.4 (on BL1.1), but recently it started force closing several applications. Also the battery indicator never ran down from 100%. So I wiped data in CWM and reloaded the ROM, but that didn't seem to help. So decided it was time to find a new ROM.
I tried to first install Vegan, but I think I used a 1.2 BL (doh). So then I uploaded BL1.2 and also latest CWM (latest version posted by DRH team). I successfully nvflashed through APX and rebooted OK into the stock ROM. I uploaded a new 1.2BL ROM (Beasty 2.2.1 +Clemsyn), it worked fine and was uploading all my apps. It powered down fine, but then would not get past the Birds on reboot. Nor could I boot back into CWM.
So went back into APX and nvflashed again, rebooted into stock ROM. *Now* before uploading any new ROMs, it is doing the same thing. Won't power back up past the Birds, can't get into CWM.
And to top it all off, I now can't boot up at all.
HELP! I am now in way over my head!!

Allot of stuff that cannot be explain can be caused by stuff from previous build being left on the internal storage. Typically what I do when changing the bootloader is making sure everything on the internal storage is backed up then wiped clean. After NVflash is complete force the tablet to boot into recovery by keeping the Volume + pressed down while it reboots or holding down the power button during the reboot after NVflash and powering down the device. Then while holding down the volume + pressing the power button to boot into recovery. Wipe date Factory reset, Wipe Cache and Wipe Dalvic Cache. Go into Mounts and Mount Data then Format also Mount System then Format. Then in Advance format Internal SD (Make sure that your external SD card has been ejected) 2048/0. This will ensure that there is nothing on the internal storage and you are starting a clean slate. Last thing is to go into mounts and Mount USB connect Tablet to computer and transfer over the ROM of choice. After tranfer is done safe removal of device through computer and unmount in CWM. Install new ROM.

I really hate to be "that" guy, but I've searched the forum, and cannot get the unit to power back on. I have taken off the cover and pressed the reset button. I've also held down the power button for more than 10 seconds, nothing. Tried the APX and CWM power up combos and nothing.
I'm not sure how this happened. It was running fine in two different ROMs, but once I powered it down properly, it wouldn't come back. At all.

These are common mistakes that I've noticed on the board.
1. If you want to format a partition, just format it. There's no need to mount it first. In fact, you shouldn't.
2. There is no need to format the boot and system partitions separately prior to a ROM install because
a) the boot partition is overwritten and
b) the system partition is formatted by the install process.
3. To wipe all user data, simply:
- Wipe data/Factory reset
or, in extreme cases
- Re-partition the internal SD card, and then
- Format cache.
Otherwise, you're just uselessly repeating steps and wasting time troubleshooting the wrong things.

See if the K1-pad short procedure shown here helps you.

After a few more hours messing around and reading boards, it appears my GTab is operating in APX and couldn't tell. I can access APX through USB. I now wonder if I had a bad BL version (I used the combo DRH version which was posted to use before the ICS ROM - I thought latest was best(?).
I tried to back down to a lower BL (1105 bekit Nvflash?), but the directions are a little confusing. Do I need to install new version of CWM first? And in terms of changing the names in nvflash file, which one?? I am starting now to care whether I get 1.1 or 1.2 working -- just something.
I'm not too proud to admit I am over my head now - I would be thrilled to see the Birds again some day.
Thanks in advance!

Which ROM do you want to install?
If you want to install any ICS ROM, just follow the preparatory steps given in the TeamDRH's ICS ROM thread.

But I can't boot into Clockwork Mode yet, stuck in APX. The GTab will not boot up at all. I have tried reflashing, but that is not helping. It completes the nvflash process, but then on reboot, it hangs on the Birds.

1. Which specific nvflash package did you flash last?
2. See if running this command in APX mode helps:
Code:
C:\SOME\PATH> [B].\nvflash --bl bootloader.bin --format_partition 7 --format_partition 12 --go[/B]
Make sure that you run the command while sitting in the directory containing both the nvflash executable and the bootloader.bin file.
