The blobs are tied to your device because nvflash works pretty much at hardware level, so without your own blobs, it's nearly impossible to recover. Here's the procedure to extract the blob before brick: http://www.xda-developers.com/androi...with-flatline/

As for "writing to bootloader", if you can't access the bootloader now, it may be because you flashed the wrong bootloader (likely from the 3G variant of the Nexus 7 instead of WiFi-only or vice versa). Unless you can somehow gain access to fastboot, you'll need to recover via nvflash.

Without the blobs backed up, you'll probably be better off replacing the Nexus 7 motherboard with a working OS and all.

are you people seriously saying that one command sent electronically through a wire can physically break a device to the extent that it is 100% impossible to repair electronically (if there are no blob files made in advance to preform a recovery). It just makes me wonder how could such a command exist (who on earth would use it). as fer as replacing the motherboard is concerned my n7 is a 32 gb meaning it will be hard to find an affordable replacement.

BTW I am pretty sure the bootloader was for the wifi version (my n7 is wifi) and I am also suspicious that the nexus toolkit had bricked my tablet because I tried the temporary boot feature and I saw in the corner something like "downloading bootloader img". At some other point in time I used the dreaded command (either before or after). I cant remember which one of these these operations had caused the brick because it was only later I noticed the tablet was in a Sleep of Death http://forum.xda-developers.com/images/smilies/mad.gif

thanks for the advice anyway

Note: Following command WILL WIPE your device.

Code:
fastboot -w update image-nakasi-ktu84p.zip

I would recommend either replacing your entire tablet or buy a replacement board on eBay and replace the motherboard yourself and then it will run like new.

guys I have managed to get my nexus 7 into APX mode by pressing the buttons on the side however I am not sure where to go from here. Every time I try to update driver in device manager I get the error "There is no driver selected for the device information set or element" and as a result cannot update it to the asus apx mode interface thing that nvflash provided. if there is any other possible course of action I can take from here that does not involve physical repair then please do let me know after all I Only plan to replace the motherboard as a last resort option

To be able to recover from APX mode, you'd have to have a backup of your tablet. Without a proper backup, you can't do much. Also, there is no way of using someone else's backup, since every motherboard has a different signature key.

Could someone confirm if my assumptions are correct?

Mine is stuck in APX mode therefore if I send it to ASUS to repair my data will lost? If the motherboard is replaced my data is lost? In its current state my data on it is unrecoverable?

Just wondering if it's safe to sell for spares, seeing that I've got no way to wipe it.
