Stuck in APX mode!! Blank screen

My pad boots straight to APX mode and there is no logo, just a blank screen.

I can flash with nvflash but after rebooting I still get a blank screen. I cannot get into recovery.

If the nvflash command has the --go parameter at the end the rom will boot. But after shutting down I again get a blank screen on reboot.

Is there a way to flash a rom within gingerbread rom itself?

I tried my original backup but it's too big for the partition!

I have tried reflashing several times - using the latest tap n tap update (6xxx).

I have used the latest guide Hannspad_Backup_Recover_Destroy and also previous one (4789)

I have tried the destroy bat file from the guide as well:

Nvflash started
rcm version 0X20001
System Information:

I have also tried my original backup of the stock rom:

Nvflash started

please can someone help me? I installed flashback and it was running fine everything working then i rebooted the pad and its stuck on the hannspad logo.

I have not got any idea what to do I see nvflash mentioned and a link to the files but all the links are dead.

I am desperate need of a helping hand. I dont suppose any of you guys live near me i am in sutton in ashfield in the UK.

Please get back to me I am really fed up and worried my tablet is an expensive paper weight now.

I am pretty sure that it is just kernel related because i forgot to flash rotations 32 kernel. I know I am a Muppet but please help me rescue my baby.

You can try my NVflash backup
http://minus.com/meEEvnEdF
Once NVflashed go into recovery and do a data factory wipe.
NVflash Quick Guide
Pad off
Pad press Volume and Power at the same time until you have a black screen again.
Connect Pad to PC
If your PC like to install a driver, choose it yourself and go to the APX folder in the Backup folder and press ok.
When driver is installed execute the hann guide. bat in the folder and let it do the work.
When finished switch of your pad. Than go to Revory with Vol+ and Power.
Than do a data factory wipe and then reboot.

If this doesnt work try my unbrickfile
http://minus.com/mG2tnRnhO
There is a Howto in English and German included.

I am having a similar problem. I have followed many guides to solve this, however, when it comes to actually using the .inf file to have my computer register my Tablet, my computer seems to not allow me to actually utilize the file & while in APX mode it remains unable to register the tablet, how should I make the Computer read the file?

I am running Windows 7 Ultimate on a 32-bit system trying to use the driver titled "NVidiaUSB.inf"
