Tried to reflash via the sd card, and it failed. Now it only boots to the dead Android. Try to flash another rom (these are stock releases) and it hangs for over a day without completing. Now it won't get past apx mos, black screen with a power light. Tried to flash via nvflash using several automated methods, they all fail complaining of various errors that seem to be related to bad partitions. I run badblocks and get errors. Now, having gone through everything short, I go to euu. That also hangs on copying the image. I'm out of ideas. is there something I haven't tried, or am I likely dealing with s dead tab at this point?
This is what I'd do, and this goes for anyone stuck on the acer logo or otherwise soft-bricked.
Run babsector.rar file.
This is the ONLY file that will give you an error that can be troubleshooted. NONE of the auto tools or the manual nvflash method will do this.
Once babsector has run, post the output and we can tell if its the dreaded hardware fault or not.

A great guide by kaijikun here http://forum.xda-developers.com/show....php?t=2450119
If you get stuck with the black screen with the power led light ON.
Hold the power button for 5 secs until it goes off.
Re-enter apx mode manually (i.e. this means using the buttons, don't use the auto tools, it won't work)
It also goes without saying, you need the acer drivers http://support.acer.com/us/en/produc...1&modelId=3851
and the drivers from the android sdk, you can download a mini zip here https://www.dropbox.com/s/x98233x397...ni_sdk_adb.zip
If you don't have your CPUID, there's no way of unbricking.
If you don't know what a CPUID is AND can still boot, read this guide here http://forum.xda-developers.com/show...1#post25429111
If you cannot boot and don't have your CPUID you need to recover it using Linux, see srbeens guide here http://forum.xda-developers.com/show....php?t=1751978
Just to say, the whole unbricking process takes some time....mostly downloading everything you need. You will also need a fully charged tab, you can sometimes use 40-50% of your battery doing this. To be safe connect your charger and leave it there till you are done.
The other thing is your PC OS...there has been mixed success with win8 and 64bit. FOr best results win7, vista and xp work best. If you are linux savvy, you're in luck, no driver issues at all with this OS!!!
The only way you can not
restore your tab to fully working order is if your tab has the faulty memory chip. And the only way to know if this is the case is to run the babsector.rar file.
