Summary: I tried to install the ROM that shouldn't be named over FLEXREAPER extreme, and now the tablet is bricked.
Previous state: A500, unlocked ICS bootloader v7, Thor recovery 1.7.3, FLEXREAPER RF1 EXTREME revision 2.
What I did:
I entered CWM recovery
I wiped data, cache, dalvik cache, and battery status
I installed Tegraowners ICS ROM v169
I installed gapps-ics-20120429 (without rebooting)
I rebooted the tablet.
In retrospect, I suppose things went wrong when I didn't reboot before installing gapps, but it's too late to change that now.
Current state: the tablet won't boot, and pressing vol-up / vol-down doesn't help.
Connecting an USB cable from Linux, I get the USB ID 0955:7820, so the tablet seems to be in APX mode. I tried flushing the boot loader from scratch, but the operation fails:
Code:
./nvflash --bct bct.bct --setbct --bl bootloader_apx.bin --configfile flash.cfg --odmdata 0x300d8011 --sbk 0xXXXXXXXX 0xXXXXXXXX 0xXXXXXXXX 0xXXXXXXXX --sync

The above bootloader_apx.bin is ICS v7.
Edit: I do have a CWM backup taken just before installing the new ROM. So I suppose what I'm asking here is, how can I get to a bootable state with CPUID, SBK, the beginning of mmcblk0, and a working nvram. Help please?

If u cannot get to fastboot volume up/power to flash a recovery
and cannot boot to the OS or recovery
U will need to downgrade back to HC. See jazzyjames rollback thread on how to do that.
Yr cpuid is listed above as 'chip uid'
Ok, solved
Thanks for the answer. I got it working with TimmyDean's tool in a roundabout way: I re-created the partitions with TimmyDean's bootloader, and that allowed me to flash the unlocked ICS bootloader and recovery. Then I rebooted into recovery and I was back in business.
I should note however that I lost all the data from the internal sdcard in this process. I'm not sure if that was the result of me futzing with nvflash, or if re-creating the partitions did that; the end result is all files are gone. That's a pain, but survivable. At least my tablet is back, which is good, because with that rounded shape it would have made a lousy door stop.

I have my own 2 conclusions and actions that i need to take: 1.) Change eMMC flash chip 2.) Give to someone who can flash it through JTAG
Which would solve the problem?

Thx for advice but that didn't help. I recieve same error in ubuntu
What else i can try?
Theres no easy fix for this unfortunately
But check the apx driver is definitely installed.
Sometimes on a failed flash the drivers get screwed upload
Connect yr mini data cable and check the system trays safely remove h/w
The Acer USB boot-recovery driver should show here.
If it is d/l the latest v0.4a500 manager/ apxFlash tool by blackthund3r
Does thisbrecognise yr tab?????
If so use bundle 17 from the in-app bundle market
Choose the default bct option
There is a thread here that ubshould look at if u haven't already
I'll track it down - if these things don't work i dunno wot will

Q] No Access to ROM or Recovery (LNX&SOS error), only apx mode avaible
Sent from my A500 using xda premium
My tablet was fine for a month, so fine I even changed my sig to my working conf.
Then I booted it up today and halfway through the boot animation it froze and shut down.
Now it simply doesn't turn on. I hold power for as long as I want and no answer, plug the charger and nothing happens.
Tablet is still detected in APX mode but nvflash is a no go too:

did you try instead of injecting a file to --read and see if you get anything using nvflash?

The .bct file is there, I have several ready to flash images on different folders and they all have copies of all the required files. I already nvflash'ed my tablet in the past using the .bct file I am using now. Unfortunately, it is not working anymore.
Already trying to RMA.
This is the same tablet I am experiencing problems with adb (another thread created by me).

Tutorial - Flash ICS v9 Bootloader manually under Linux.
I am writing this tutorial, because I was unable to replace the HC 3.01 bootloader under Windows with the ICS Bootloader.
This is a translation from the German tutorial at Android-Hilfe.de written by me (aka Brickerl).
Preparation: Tablet must be in APX Mode.
Turn your table off!
Use a paper clip and press the Reset Button softly. You can feel a soft resistance.
As you press the Reset button hold also the Power button. Do this 3 seconds long.
Now release the power button and the paper clip.
The light of the powerbutton glows now white (at least it does for me) und the display is black.
Files needed (see attachment):
bct.bct
flash.cfg
nvflash for Linux
bootloader_apx.bin
bootloader_v9.bin
Your SBK number!
We write a script. I call it a500.sh.
Make a new file. e.g. with vi.
Code:
vi a500.sh
Write this into the script file.
Code:
#!/bin/sh
./nvflash --bct bct.bct --setbct --bl bootloader_apx.bin --configfile flash.cfg --odmdata 0x300d8011 --sbk 0x12345678 0x12345678 0x12345678 0x12345678 --sync
Modify your SBK.
Make the file executable.
Code:
chmod +x a500.sh
Execute the scipt as root. Dont worry there is no flashing yet. If there are some status messages all is ok. Otherwise cancel NOW or your tablet is bricked afterwards.
The status messages can look like this.
Code:
# ./a500.sh

Step 5:
Now the actual flashing begins. We add 3 lines to the script.
Code:
#!/bin/sh
./nvflash --bct bct.bct --setbct --bl bootloader_apx.bin --configfile flash.cfg --odmdata 0x300d8011 --sbk 0x12345678 0x12345678 0x12345678 0x12345678 --sync
[B]./nvflash -r --format_partition 4
./nvflash -r --download 4 bootloader_v9.bin
./nvflash -r --go
[/B]
The output can look like this:
Code:
# ./a500.sh

Nice little guide mate. Thanks for contributing!

Yeah good stuff, will post a link from the root guide when I get back to my pc...
This is perfect for those running ics/jb roms BUT still on the HC bootloader and custom recovery, you may want to make that clear.
The other thing you may like to do is to add instructions to flash a custom recovery. The .img files can be found in the v8 bootloader.zip (not sure about v9.zip) This would be perfect for those who just cannot get flashed using windows for whateva reason.

Step 5:
Now the actual flashing begins. We add 3 lines to the script.
Code:
#!/bin/sh
./nvflash --bct bct.bct --setbct --bl bootloader_apx.bin --configfile flash.cfg --odmdata 0x300d8011 --sbk 0x12345678 0x12345678 0x12345678 0x12345678 --sync
[B]./nvflash -r --format_partition 4
./nvflash -r --download 4 bootloader_v9.bin
./nvflash -r --go
[/B]
The output can look like this:

Can you help me please?
Hi, I'm new to this forum and pretty much new to rooting/flashing tablets of any kind. I have a Acer a500 with stock rom which just broke down a couple of days ago for no reason. After much googling and searching this forum I have figured out that it is stuck in apx mode and I've tried everything I can to fix it but so far nothing has worked. Suffice it to say when I use nvflash I get this error.

I assumed my partitions were corrupted so I've tried running babsector but am unable to start up in recovery mode after running a501 A.bat. I've also tried many other things but nothing has worked. Does anyone have any suggestions? I'd really appreciate any advice. Thanks!
procedure
for babsector to work you need to run A then reboot to APX mode - then run B if it shows an error than it will be a hardware failure

Just wanted to note that when I tried to flash using blackthund3rs apx flash tool my tablet shows a green acer logo in the middle of the screen and in the top left it says something like entering apx mode, but when I run the babsecter it has the normal white acer logo in the middle of the screen and in the top left it says entering acer download mode. Don't know if that is pertinent or not but just thought I'd mention it.
So from the results above does it sound like my tablet is just not going to be revived? Is it a hardware failure for sure?
hardware
looks like it
you could reflow the board just do a search in forum on reflowing for procedure
