[G Tablet Q&A, Help & Troubleshooting] Breadfan209:
All,

Been lurking for quite some time - I've used the info via search to install 2 different ROMS (VeganTab 7.1 and SmootherBean 4.1.2) over the course of the last year or so. I decided Friday night I'd give another one a try...and that's when things went south.

I'm well versed technically, and have no issue using or understanding nvflash, APX mode, etc. So, my first two forays into getting the G-tablet setup went real well. I enjoyed the process and the results were great.

So anyway, I am about to start the process for the third ROM, giving Harmony JellyBean a shot.

Upon shutdown of my tablet from SmootherBean, things got funky. I *may* have left the USB cord in the tablet and my computer, as I was backing up a few files before starting. But, I think I pulled it out. I don't recall, because I didn't think I was going to have an issue at that stage.

Basically, the tablet went dark and then it appeared to refuse to power up. I decided, since I hadn't started loading anything, or attempting to nvflash anything, that it was removed from my upgrade process - this happened before cracking into a new ROM in any way, aside from backing up data.

So, I ended up opening up the gtablet and followed the instructions I found searching to pull the battery cord and reset it. After I did this, it booted up - but not normally. It booted to the SmootherBean lock screen, but had no touch screen.

So then I made what was probably a large mistake. I figured since these things are hard to brick, I'd go ahead flash it with the Team DRH 350mb version via nvflash and then just install Harmony Bean. My gTablet hasn't booted properly since.

Currently all I get on boot is the 3 birds, and then a few seconds later, there appears to be about a 5-6 pixel "band" that turns black on the bottom. Otherwise the image doesn't change. Trying recovery mode boot is the same - it states it's booting to the recovery kernel, but then the black band appears on the bottom and it goes no where. I've let it sit minutes, even over an hour....no go.

So, I've spent time this weekend off and on, searching these forums for any tips I can find. I've tried the bekit full stock flashes, the format jobs, opening the tablet and pulling the battery, shorting the contacts, some of the CWM based nvflash files, just doing the recovery image, etc.

The last one I tried seemed like it was the "be all" for this type of situation: Restoring the G-Tablet from a failed recovery found here: http://xdaforums.com/showthread.php?t=1167944

So I staged everything and began, and same deal, as soon as I get to any steps where it should boot, it refuses to. It just shows that darn black band of pixels below the 3 birds image after a few seconds.

I get the feeling it's got a message behind there, I just don't know what it is. :)

So - basically I've been unable to get this going. Is there anything else I can try? I've tried the TeamDRH ICS and JellyBean nvflashes, the bekit stock, 3028 w/ cwm, 5504 w/ cwm, (both 1.2 branch), etc.

Here's a few things I'm probably doing wrong, or did wrong during this ordeal:

1.) Possibly left the usb cord in when shutting down the tablet running SmootherBean. Is that a problem if so?

2.) When opening the gtablet, I did, sad to say as this is embarrassing, damaged the ribbon cable going to the camera. About two of the copper leads in the cable are damaged. I removed the camera as a result, but put it back in to see if that would change things. I did this damage on the initial opening of it, and it did boot (albeit w/ no touchscreen) afterwards. I don't see how the camera attacheds to the touchpanel so I don't see them as related.

2a.) Could the device be looking for the camera on initial boot and fail with it missing or broken?

2b.) Did I mention that was an embarrassing goof? Heh... I've done plenty of board work and small soldering, opened most of my electronic devices, modded many, so embarassed I damaged that cable...

3.) I can't recall if my tablet was a 1.1 or 1.2 branch device. I've tried both though...all things I nvflash have he same symptoms upon bootup.

So....what do you all think? Could this simply be a hardware issue? Am I doing something way wrong? Any tips beyond search?

I've searched and searched for hours, and read tons of posts and tried many things - the only thing I couldn't find was any reference to a damaged camera and/or this black band of pixels that appears seconds after booting up.

I think those birds are laughing at me. :D

Thx in advance, this place is a great resource for info!!
