Editing this as I'm desperate for help and things have moved on since I first posted, below is where I am up to post 8 of this thread.

I flashed Vegacomb b (exe), it restarted but stayed on the warning about paying for vegacomb for 10-15 minutes which didn't seem right so I held power for 6 seconds and it turned off. After that it would never turn on or go into recovery (I know all the methods, none worked).
Today I unhooked the battery, when I plug the battery back in the screen comes on for a second but then it's as it was, unresponsive. HOWEVER, if I plug the mains in with the battery disconnected then it immediately tries booting but still sticks at the warning (left for over 20 minutes). If I plug the battery in while on this screen then remove the mains it stays on. The power button is unresponsive through this so I still cannot get into recovery.

Any more ideas that haven't been mentioned?
I've tried well over 100 times to get into recovery but it's not happening

original post
Hi guys, just managed to (re?) install Vegacomb (b, from exe), it restarted but stayed on the white screen with the warning text about paying for Vegacomb for over 10 minutes so I held down the power button to turn it off, now I cannot do anything to boot it up (tried holding power button down from 0.5 seconds to 60 seconds!), it also won't boot into recovery. Is there anything at all that can be done to get this going?

cheers

OK, I've tried holding down back while plugging in (fully charged btw), tried all variations of button presses with back and power, with and without USB, with and without power cable.
Only got until 10PM (UK time) to get this sorted (it's now 6PM) so any help/advise would be appreciated

Hi, mmace...

Sounds like you need to reflash... try the following;

To nvFLASH MODDED STOCK, VegaComb 3.2 BUILD 9B, or the OFFICIAL STOCK ROM:

If you haven't already done so, you will need to install the Windows USB System driver http://www.myadventvega.co.uk (The STOCKROM can also be found here).

Download and EXTRACT it a folder on your PC (eg. C:/ADVENT)

Connect your Vega to your PC, via a USB cable.
Connect your Vega to the mains, via the charger.

On the Vega, effect a FORCED POWERDOWN by long pressing (6 seconds) the POWERBUTTON.

Now to enter nvFLASH RECOVERY MODE...

Press and hold the BACKBUTTON for 2 seconds
Still holding the BACKBUTTON, press the POWERBUTTON for 2 seconds
...and release...
But continue to hold the BACKBUTTON for a further 2 seconds.

Upon succesfull completion of this key press sequence, your PC will either direct you to install the USB System driver (in which case, point it to the folder as detailed above)...

...or it will 'ping' the 'found new hardware' sound

Now, on your PC, you can double click on the MODDEDSTOCK .exe (or whatever ROM you wish to nvFLASH).

--------------

The whole BACKBUTTON>POWERBUTTON>BACKBUTTON sequence requires precise timing...

An alternate method (by partner) to get into nvFLASH RECOVERY that seems to have worked for some is as follows:

1. Unplug from the charger and the computer
2. Press back (Don't release it)
3. Plug in the charger
4. Connect to the computer
5. Press the power button
6. Wait more than 2 seconds and release the back button

Hi, mmace...

cheers mate, but tried all that (just tried again too) as I've been through all the "bricked" threads but it's still dead

You could try, as your thread title alludes to, a battery pull (if you're feeling brave!).

A battery pull can be accomplished as follows (never tried this myself, and personally, I wouldn't recommend it, unless all other options had failed.)

Assuming you're running a Vega (you don't specify), and not one of it's variants...(POV/Viewpad)

"...Remove the four rubber pads in the corners, unscrew the small Philips head screws and gently separate the rear cover (it has plastic clips that help hold it in place. Then there is just one push fit connector to disconnect. "

...and then try nvFLASH again...

...good luck...

Cheers, will give it a go, it's practically dead at the moment so nothing to lose!

[GedBlake]

It might be worth leaving the battery out for a couple of minutes or so, to allow any residual capacitance to die off.

Disconnected battery for around 10 minutes, put it all back together, still can't boot or get to recovery
EDIT: it works when the battery is disconnected

HI
Is it possible that the battery is Kaput. If the tab works on the power lead but  not the battery
it would suggest that the battery, if not dead, is faulty, and although showing charged, it
is not. Other than obtaining another battery I do not know of any other remedy.

Hi mate, the battery is fine, if I disconnect, plug in mains it goes to warning screen, if I then plug in battery and remove mains it stays on that screen

[piran]

This may be a silly question - but are your buttons actually working (the power one obviously is) I had a problem where my power button broke - there was no movement on it at all so I couldn't turn the thing on/off, is your back button moving ok ?

"...it works when the battery is disconnected..."

What does ...?

Assuming you are on mains power, via the charger...

Do you see the blue LED (top right hand corner) flashing ON and OFF.. (when on charge)
Do you see a completely black screen?
Do you see an illuminated black screen?
Does is it BOOT?
Does is it attempt to BOOT?
Does it BOOTLOOP?
Does it FREEZE at the first screen?
Do you see the 'VegaComb is free software...' screen

When trying to nvFLASH, what PC operating system are you using...
Windows XP, Windows 7 (32bit or 64bit) - (Could be a driver issue!?)

Details, please...

What does ...? starts to boot and gets to the "VegaComb is free..." but stays there. Cannot shut it down, cannot start it in recovery

Assuming you are on mains power, via the charger...

Do you see the blue LED (top right hand corner) flashing ON and OFF.. (when on charge) - not when the battery is disconnected, but if I connect it up then yeah
Do you see a completely black screen? - if I have the battery connected then there is no response at all from the tablet
Do you see an illuminated black screen? - only if I disconnect the battery and plug in the mains charger, this is for a second or so before the warning about vegacomb being free
Does is it BOOT? - no
Does is it attempt to BOOT? - if I disconnect the battery and use mains then it gets to the VegaComb is free... screen but never goes beyond that
Does it BOOTLOOP? - no loop, just stays at the warning screen
Does it FREEZE at the first screen? - yes, if I disconnect the battery and use mains
Do you see the 'VegaComb is free software...' screen - yes, if no battery

When trying to nvFLASH, what PC operating system are you using...
Windows XP, Windows 7 (32bit or 64bit) - (Could be a driver issue!?) - Windows 7 32 bit

Details, please...

Answered what I could above in bold.
If I disconnect the battery and connect the mains it begins to boot, I can then connect the battery while it's doing this and disconnect the mains and it stays on.

looks fine, when I had it open I could tell it was moving something on the circuit board

Definitely sounds like a battery issue to me...

Have you tried charging the Vega for 6 hours or so, until the blue LED stops flashing...
(ie, does the LED stop flashing after a full charge cycle, in other words, is the battery capable of holding a charge?)

Where did you get the Vega from... is it new or a refurb. ?... Did it come with VegaComb preinstalled?
What is its provenance/history?

Short of acquiring a replacement battery, I am not sure what else can be done
...unfortunately...

yes, the first 48 hours of trying was with a fully charged battery
Vega was 2nd hand from eBay, it worked fine for 4 months, it wasn't rooted when I bought it.

there's no cheap/broken Vega's available and it doesn't appear that you can buy batteries for it

I know it will sound a bit silly, but change the order to enter nvflash:


1 - Unplug the tablet from the main and the computer
2 - Plug to the main (left the computer unplugged)
3 - Presh back and hold it until the end of the process
4 - Plug to the computer
5 - Wait some seconds (5 or so, more than 2 anyway)
6 - Release back button
7 - Try nvflash

This worked for me and a couple of guys from tabletroms. Good luck

Just come back to it after 10 days, plugged it in and it started to boot immediately, went to the warning face thing for around 10 seconds then rebooted, it did that 3 times (me pressing power did nothing) and now it's back to where it was

I disconnected the battery again, plugged it in with back button held down and it went straight into recovery mode (back button works, have right drivers etc). I started running Vegacomb HC 3.2 9b exe and it pushed files to tablet (system.img was last), the tablet then booted to the warning screen for 5 seconds or so and then went off and back to being dead again. The CMD box on the PC said it had copied system.img successfully and to press Enter to continue but that closed the window, nothing seemed to install

I'm stuck

Is there any particular reason you are choosing to use the 9b version of Vegacomb?
My previous experience of Vegacomb 9b gave me the same results whereas loading modded stock V2 and then Vegacomb 9n via CWM gave me a working tablet.
Just remember if you go this route that you need to set the time and date and setup the wifi in modded stock before flashing Vegacomb 9n otherwise you may find the wifi will not work and the time and date keeps showing incorrectly.
You could try flashing VegaICS onto your tablet instead as that is an NV flash format install, personally though I would think of starting small and building your way up just to check everything works correctly, so flashing modded stock and then Corvus5 via CWM might be a good starting place and if all works then you can wipe your tablet and flash Vegacomb 9n onto it.

It does exactly the same with modded stock
