ERROR: Can´t installl hacked ICS Bootloader
I tried installing Hacked ICS Bootloader in Order to get Moscow Desire´s "Alexandra V a501 ICS 4.0.3 ver 1.4 Final" running on my a501.
The following ways of flashing could get the hacked bootloader on my a501:
"Afterota for A600/G100W" (http://forum.xda-developers.com/show....php?t=1675939),
"blackthund3r´s ATX flash tool A500APXFlash.exe" (see "Automated flashing tools" at http://forum.xda-developers.com/showthread.php?t=1622425")
"Manual flashing via nvflash" (see Manual flashing at http://forum.xda-developers.com/show....php?t=1622425)
Trying to flash with this tools always brought me to a Command Promt saying:
Nvflash started
[resume mode]
APX flash tool hang when it tired to Format Partition 4 etc.
and then doing nothing even if i let it stay for hours. No Information or Error so long.
When i tried flashing manualy (see link above)i finaly saw an error:
failed executing command 25 NvError 0x120002
command failure: sync failed (bad data)
bootloader status: partition table is invalid, missing required information
e: 14) message: nverror:0x4 (0x4) flags: 0
So it seemed however that the partition table on my a501 got messed up. Asking google for "failed executing command 25 NvError 0x120002" brought me to an answer "lcd047" posted on tegraowners (http://forum.tegraowners.com/viewtop...p=15285#p15331)
He desicrbes same problem with messed up partition table an restoring it with timmyDean´s root-3.2.1-V4.7z (http://forum.xda-developers.com/show...&postcount=1):

"I downloaded timmyDean's root-3.2.1-V4.7z

without rebooting, I flashed the v7 bootloader and recovery as per the bootloader thread; since the partition table was restored at the previous step, the operation now succeeded;
I rebooted the tablet in recovery, and proceeded to wipe the data and flash a ROM the usual way.
And that worked for me. After flashing, my a501 did a automated reboot, i quickly killed the reboot by holding the Power Button (guessing killing the reboot is not realy necessary because the booting shouldn´t mess up the partition table again) and then brought the devive back to APX Mode (Holding Reset and Power for 3-4 sec. then releasing Power and after 1 second relesaing Reset).
Then i flashed the hacked bootloader via blackthund3rs APX flash tool (see link above).
Then i installed Alexandra V as Moscow Desire descirbes (see "To Install" at http://forum.xda-developers.com/show....php?t=1635577)
It took my 2 days of trial and error, but finaly give me a nice working Alexandra ROM on my a501!
Hope this helps people having the same issues.
Thanks to Moscow Desire, civato, blackthund3r, gersma, zeroNull, lcdß47, timmyDean

Note from MD. You guys take note of this. Sometimes, when you get corrupted partition tables, you may have to go back to an HC stock bootloader to get them fixed. Of course there are other methods, but require some indepth knowledge, and this method most people can do easily.

Help
i'm use a501 3.2.1 stock HC and still unroot.
Now i wanna use alexV ROM, so i have flash ICS BL use blackthunder's flash tools and it's success, with V8a50pub recovery.
but my problem is:
1. still able to boot my stock HC ROM,
2. can't boot into recovery mode, it will display green robot with exclamation in its body
3. can i get guide to flash cwm recovery? i want use CWM-install-A500PubRecovery_v0.2.zip but its extension is .img and i dont know how to use it
sory if i asked noob question
thanks

Go on youtube and just search up how to root acer a500 , its the first video, steps are simple but i'm not too sure you can use pub recovery on honeycomb, after that use one of the flashing tools to install the hacked bootloader ( i prefer the apx flashtool, its fool proof pretty much with the sbk generator built in ) and download the v8 bootloader with your recovery choice and install it, there's even a guide on youtube on how to do it, hope it helps

So, While this did not actually work in my case, it led me to do a search on "TegraOwners" for "Partition Table damaged" where I found "BadSector" which totally fixed my problem. So, A Hearty thanks to you Moscow Desire, as well as to BlackThund3r, for without his direction, I never would found your post either.
That being said, a big thanks to all the Dev's on this site, for without their hard work, there would be no reason for any of the fine information available on this site!

Hey i have a similar problem and i cant figure it out ..heres what i get:

If these 2 tools "don't work" there are only 2 possibilities
a) you're not doing things correctly
b) your tab has a faulty memory chip and needs a replacement motherboard

[Q] Problem loading custom ROM to A501

Hi,
So I thought I'd explore the world of custom ROMs on my Acer Iconia A501, which was previously on ICS. I used the A500APXFlash application to flash the tablet and managed to install CWM. Stupidly, I downloaded the Evil Alex II patch instead of the full ROM (just didn't realise), and wondered why it wouldn't boot. Finally when I realised what I'd done, re-did all the wipes, reformatted system & flexrom, and tried to install the full ROM, it did work briefly, but the Wifi crashed out (wouldn't respond) and I was getting a bunch of errors on google apps and google play, so I decided to reboot and ended up back stuck on the "Booting primary kernel image" screen. I've since made a few attempts to reinstall the ROM and even re-flash, but couldn't get anything different to happen.
I finally decided to roll back to a stock ROM, in case my initial mistake of trying to install the patch only had corrupted something. I could only get this working via the EUU packag, but this managed to get me back to Honeycomb and all seemed ok. So I thought perhaps I'd try I flashing again and then installed the root package which seemed to go fine. Then I tried the custom ROM again - no luck. Constantly stuck on that damn "Booting primary kernel image" screen.
I've watched a couple of video tutorials on flashing and installing a custom ROM to the A501 and I'm certain I've followed all the steps correctly. I've checked the forums and mostly this seems to be solved by reflashing and/or reinstalling the ROM, which I've done more times than I can count. Short of going back to the Honeycomb stock ROM (or maybe getting to an ICS ROM somehow), I've no idea what else to try. Can anyone help?

I think you should try to wipe the tab properly. Boot into cwm.
Under backup and restore activate toggle... of internal memory or similar
Go under Wipe menu and wipe cache, dalvik and battery stats, and wipe userdata.
Under Mounts and storage format system three!!! times and then format flexrom.
Flash your rom.

OK, so I have tried toggling the wipe of internal memory a few times before, and it never made a difference. I'd never tried formatting system multiple times (I assume that's the only bit that I needed to do three times). In any case, I followed your steps and no luck. Still "booting primary kernel image". Thanks for trying. Happy to try almost anything at this point, as long as it doesn't brick it.
I don't need to mount system or flexrom before or after formatting right? I'm assuming not, cause nothing has ever said to, and I don't think doing it before would make a difference. After maybe...

Lets hope u haven't already......
Honeycomb stock is unrootable and therefore unflashable.....d/l timmydeans v4 euu

You won't have 3g for the moment but u will get cwm and root. From there u should be able to reflash the unlocked bootloader if u wish...
You may have some luck with the update.zip method check out

So that file you linked didn't have any PDF, just looked like a ROM, so I tried the update.zip method with a stock ROM I already had instead (which I had tried once before without success). The first time, still stuck on booting primary kernel. So I tried a different ROM. That one came to the Skrilax_CZ Bootloader screen, told me it was applying the update, which then failed, and then everything went wrong. Now nothing works. I can get into APX mode, but no longer have CWM. My googling finally brought me to another thread where I found the zip for timmydean's v4 euu but it won't complete. I had used another EUU package last night (possibly the same one), but it similarly won't complete.
So now I'm beginning to worry that it really is bricked. Thanks for your help, but I'm guessing I might be out of options.

Yes, sorry. A stock update.zip. The first one didn't take, and I ended up back at the Scrilax_CZ bootloader screen, stuck on booting primary kernel (the same screen I've found myself at everytime I've tried to install a ROM).

I went back into recovery mode and tried a different update.zip version, since the first one didn't seem to have worked. However, this time, instead of getting stuck on the booting primary kernel screen, it came to a screen which still had the bootloader message at the top, and then something about updating. My assumption was this is what happens after you correctly install a stock update.zip - that it may need to get out of the bootloader to wipe it fully, install the update.zip and then reboot again. What happened instead was the update told me it failed, at which point, I couldn't get back to the bootloader and it's stuck in APX mode.

No error, it just sits there for over half an hour without the progress bar moving. I know it's supposed to take a while, but that seems too long.

Power and anything leads to nothing on screen. The power LED will come on, and it can detect APX mode so the EUU package can try and do it's thing, but it just hangs at the same point (judging by where the progress bar stops). What is the rocker switch method, I can't seem to find anything on it?

Put update.zip on an sd, go into recovery menu, wipe, install zip from sd, select update.zip, wait til it says complete, then reboot.

Well, the tab has been off since I gave up on it last night, but also plugged into power. If I unplug it from power, I can power it down fully so the power LED goes off, but if I plug the cable back in the power LED comes back on. Which suggests it may be charging?

Yes, no CWM, won't boot. Power on (with or without volume buttons) seems to bring it to APX mode - power LED on, black screen, detectable by the EUU package.

this is based on nvFlash and if windows detects it as u say, then u should be all good...then go to here and thank Danny2 for a great post..

I had what looks like the exact problem, used BABSECTOR from here http://narod.ru/disk/53919831001.a235ea2225f319015f30c009629d2075/BabSector.rar.html and fixed my tab easily.
I edited the batch files by entering my sbk directly into them, (so I wouldn't have to retype & possibly make an error) but they worked for me. (To fix the same problem you have.)
Once you are able to write & format partitions again, you can follow various paths. The usually recommended path is TimmyDeans, or the HoneyComb 3.01 EUU from http://forum.xda-developers.com/showthread.php?t=1816560.
Both use the EUU method, both should work, Both take you back to HC, where you can follow the upgrade path on google play to get you back to stock 4.03. (It's a little more involved to get back to 4.03 with TimmyDeans.)
However, I found that I prefered to install this ROM http://forum.xda-developers.com/showthread.php?t=1969887 directly after running Babsector. Follow the directions exactly (including installing the correct bootloader) and you should be able to go from where you are now, (Only APX available) to a very nicely functionin ROM, in a lot!!!! less time than following the Stock upgrade path. (You
might make mistakes along the way, just start again, it will almost certainly work out.)
Coincidentally, this ROM will also give you OC, along with many other options, & is highly customizable, is still an ICS Rom, so doesn't suffer from the memory leak probs I believe affect all current versions of the hacked JB ROMS.

yup its looking that way I'm sorry to say
sorry didnt expklain the no-spaces very well at all
some folk have had issues entering their cpuid into the sbk generator - they have by mistake copy/pasted an empty space with their cpuid which the generator recognises as a "character"
the format for your sbk is 4 sets of hex values that should look like this "0x22222222 0x11111111 0x000AAZZZ 0x00000AAA"
apologies for the ambiguity

So, a few weeks later and with a friend who had successfully rooted his phone, we tried one last time to fix it. For some reason, the tablet decided to boot into a Honeycomb (3.2) A501 ROM (without us doing much to it), so clearly something took, possibly from a few weeks back (not sure why it chose not to work then, but whatever).
So, I followed steps to downgrade to 3.0.1 and root, then ran blackthund3r's APX flasher to reinstall Clockwork Mod, which also took nicely. Then I carefully followed the steps to install the Evil Alex ROM (and made sure I downloaded the actual ROM this time and not the patch). Again, this all went fine, until I rebooted. At this point, it got to the ANDROID logo screen, but got stuck there. After about 10-15 minutes, I decided to reboot again - same behaviour. So I went back in to CWM, followed the steps above to perform all wipes, format system 3 times, then format flexrom again, reinstall the ROM. Now it gets stuck on the Skrilax_CZ's bootloader screen with "Booting primary kernel image" screen. I can still happily get into CWM, but I'm at a loss what else to try.
The only difference in what I did between the first install of the ROM (where it got to the ANDROID logo screen but no further) and the second was to remove the SD card after installing the ROM (before rebooting). Well, apart from also formatting system 3 times as mentioned above. I'm assuming removing the SD card or not shouldn't make a difference since the ROM should be installed by that point anyway.
Any thoughts?

Cannot install custom ROMS or unlock bootloader [SOLVED]

I have been trying with every guide and every video I've found to install a custom ROM (CM10 FLEX). Youtube videos generally tend to leave out the fact that you need to unlock the bootloader first. So I go to bootloader guides and follow those and nothing seems to work.
I have attempted to use Blackthunder's Manager and Flasher tools to get it working and something always hangs or gets stuck. With Blackthunder's app it was stuck at the "uploading image" phase. Same goes for AfterOTA.
I'm sorry I'm being vague, but it'll be hard for me to type out every scenario and every program I've tried since I literally just spent 3 evenings and about 6 hours trying with this. My google results are all red because I've looked at every thread already and every guide.
So I'd like some fresh advice and opinions. Where should I start? It's a rooted A500 running ICS (from the standadrd acer update) and is pretty much stock

If a500 manager hangs u will need to flash manually using nvflash.
Civato has a guide stickied in dev forum.
Basically download the v8 bootloader.zip file, extact it, put yr tab in apx mode and run the .bat file.
You will have the option to flash a custom recovery along with the v8. After the flash boot directly to cwm and flash yr rom! Done...

It was running in APX mode and the A500 was showing that it was in APX mode. How would you recommend I get into APX mode? I ask because I've seen various guides that have different ways. The only way I was able to get into APX mode was using Blackthunder's flashing tool and when the A500 was in APX mode I used the other tool (while abandoning blackthunder's tool) to try and flash it.

The device manager wasn't showing an APX device and neither was the "safely remove hardware" tool, but the tablet was still showing it was in APX mode.
I just now tried the "AfterOTA" tool and the tablet says it's in APX mode, but the tool has been stuck on "3/5 Flashing kernel" for about 5 minutes now.
While it was in APX mode again I tried starting the Blackthunder tool. After it failed to start the first process, I closed the command prompt window and it appeard to continue through the process. It got to the "Flashing Bootloader (EBT) stage one - formatting partition..." stage, and in the command prompt it said, "Formatting partition 4, please wait..." but after about 10 minutes....nothing.
Upon a reboot nothing has changed. My tablet isn't bricked and the SD card contents are fine. While it said it was formatting the partition and throughout this process I didn't see anything about "APX" devices in the "safely remove hardware" tool or in the device manager. Though I think I do require a reboot, as now my flash drives arent even showing up in the "remove hardware" tool.
I tried the blackthunder tool again, and I still don't see an APX device in "Device manager". Before it enters APX mode I see an ADB device. But when the blackthunder app says it's in APX mode (Acer screen is completely black) I don't see an APX device in device manager.
However, when I proceed to the next step using blackthunder's tool, I get a green "Acer" logo and in the upper left corner it says, "acer iconia apx mode." And this is where it gets stuck. The black command prompt says, "NVflash started [resume mode]" and the blackthunder program says, "flashing bootloader (EBT)- stage two - uploading image.
I do have the entire android SDK (latest as of 14 Sep 2013.) So I do have adb/fastboot.

K m8 - something is defo amiss -download babsector.rar in the root guide. This will reset yr partitions and flash bootloader and recovery. It will also detect and display any errors.
When u r having probs like yrs it is best to put ye tab inapx mode via the button combo and flash manually, pls post the output of commands....but I have to say its sounding suspiciously like yr memory chip is faulty...we will know for sure once you've run babsector!

I downloaded babsector, but it looks just like nvflash. Are they the same tool?
Also, I have never once gotten the tablet into APX mode using the manual method (power + reset button, right?). Every time I hold the power and reset button, wait for it to reboot (3 seconds) and release the buttons (power button first) it just powers up like normal.
-edit-
Also, I've been searching for a while now and I can't seem to find a guide showing how to use babsector. Do you have a link handy? What guides I did find said to run "A501 A.bat" first, and when I do that it asks for my SBK and then says "nvflash started. No usb devices found. Press any key to continue..."

My question will sound odd, but from what I've read above, it looks like your computer doesn't see your tab in APX mode:

I remember mine seeing it when I was under APX mode, are you sure you have the right drivers installed ? I would not proceed any further until the comp sees the tab under APX.

yes, the proper drivers are installed. I believe the issue isn't related to the tablet, but something in windows (a service, maybe) that I disabled.

-edit-
upon rebooting the tablet it came up with a skrilax bootloader. I entered recovery mode since the primary and secondary kernels failed. I was able to follow the usual guides and install the ROM. However, now it wont boot. It just gets stuck at the bootloader since there's no valid kernel image. What now?
-edit-
Looks like it was messed up partitions. The fix was to put the tablet into APX mode, run babsector, and then proceed as normal.
I tried installing the ROM again and it worked fine this time. It's loading up now. But it's stuck on the "android" screen with the flashing animated "android" text. It's been doing this for about 5+ minutes now. How should I continue?
-edit-
I tried another ROM since I am able to get to the recovery console. I tried CM-10 unofficial (before it was CM-10 FLEX). I get the animated cyanogenmod loading screen and then nothing. It just sits here loading.

Well from what I remember, when I encountered that kind of problem on my devices, I made a total wipe and reprocessed the installation.
Just to be sure I would under fastboot do:
fastboot erase userdata
fastboot reboot
then under recovery, wipe factory and format flexrom. then re install.
Hope this helps.

I did do total wipes before each install. I wiped the cache, did factory resets, and wiped the delvik cache.
When I try "fastboot erase userdata" it just says "waiting for device". I am at the CWM Recovery v5.5.0 main menu. Which mode should the tablet be in?

First you need to be in fastboot mode, instead of going into CWM by pressing "volume down" while it's booting, press "volume up" and choose fastboot mode.
Also if you have an error message while doing that, maybe you'd like to take a look here: http://forum.xda-developers.com/showthread.php?t=1431907

That did it. I didn't know about the volume up option. I did the fastboot stuff, cleared the cache and did a factory wipe, re-installed CM-10 unofficial, and I just rebooted 8 minutes ago (I'm timing it.) still nothing. Just the cyanogenmod logo with the animated swirl going around in circles.

there are 2 bat files with babsector.
after running the first one, you reboot to recovery and do a full wipe.
there is an option to "enable data/media" do that and it will fully wipe your device. I think its in the mounts and storage menu.
Once you do that flash your rom.
On reboot you must see "skrilqx_cz unlocked bootloader" displayed on-screen
If you don't have this then fastboot will not be available.
Rerun either babsector or the v8/v9.
To enter apx mode manually - You must be sure you are holding in the reset button...otherwise your tab will boot normally as you have found - using a paper clip ( or anything "non-pointy ended ) you will feel the button push in.
(Try holding the tab on its edge on your lap with the power button on your left and the reset button on top)
Press in and hold the reset button
Then press and hold the power button for about 3 seconds.
Then after a second or so release the reset button.
The time part isnt critical, its the delay between releasing the buttons thats important AND having the reset button puched in.
Once skrilax_cz is installed, you can enter "fastboot" by pressing power/vol up
Choose fastboot from the menu ( there may even be an option on the menu to wipe)
Connect your tab to yr pc and open a command prompt on the fastboot folder.
Enter your erase commands and then "fastboot reboot".
Oh and also - u said you were running stock ICS - if you lose your custom recovery and end up with the dead android screen, you will have to delete the .boot.p file as stated in the guides.

I don't know if I'll be able to help you much more than that as I never faced that problem (well that one persisting never happened to me on the Iconia, it did on the SGS i9100 but it was because of a faulty kernel)
You could try to flash first a rom like the one from civato, RE-FLEXxx-ShellSHOCK, see how it goes, also are you formating flexrom ? (from advanced in CWM), it helped sometimes.
Btw I'm using CWM public recovery v0.2 (based on CWM 5.5.0.4, there's a thread in dev section), along with bootloader V8. Never had a problem using any rom with this one.
--edit
My bad, I said flexrom format was in advanced, it's in mount/storage menu.

I've only run the first batch file, batch file A.
I finally got it into APX mode, ran batch file A, and reset everything. However, there is no "enable data/media" option under the mounts and storage menu. I have:
mount /system
mount /data
mount /cache
mount /flexrom
mount /sdcard

ok here we go...grab yr beverage of choice
boot.p file is a file on stock roms that overwrites your newly flashed custom recovery..if you still have cwm you dont need to worry bout it!
The reboot shouldnt take that long - maybe 10mins at most.
You will need to go in and wipe EVERYTHING twice! Yes twice!!
this means System, flexrom, Data and cache. After erasing/formatting System you will not have an OS so be sure to flash a rom before rebooting.
Either fastboot erase or cwm format - (choice is yours but I find fastboot just as easy but its unforgiving..you do not want to muck up in here!!!)
You may want to update to the latest cwm - heres a recovery.img http://forum.xda-developers.com/attachment.php?attachmentid=2238701&d=1378452510
Put it in the folder where you have fastboot. Then boot to fastboot andenter
fastboot flash recovery cwm_1.7.3_recovery.img
EDIT: did u run the 2nd bat file from babsector??

[Q] Stuck in APX mode. No CPU ID. Help.

So I did have a file will all the the information CPUID. SBK. Everything. But now I can not find it (I have apparently deleted it at some point).
I tried flashing a new rom and it bricked my tablet. I also can't boot into recovery because the volume buttons are broken. So all I've got is APX mode. Is there anyway to get out of this with out a CPUID? OR is there a way I am able to find my CPUID when I am not able to boot (and start the ADB service). I have tried everything I can think of and have searched the internet with no results.
I have an acer A500

See cpuid guide in my Sig there are 8 methods to retrieve it. Any nandroid backup stores in a txt file in the backup folder.
Not having volume button is gonna add to yr probs if apxflash cannot boot u to apx mode and get u yr cpuid.
If u have the unlocked boot loader you can hook up to yr pc and use fastboot to get u into recovery. Once yr tab is running again install a reboot app or flash a cm Rom which has reboot options in the shutdown menu.

Hi Dude Dibb
I succeeded this night to solve my trouble.
After using APX tool flash, I played again with the BabSector by changing bootloaders, recovery and flash.Cfg
Of course same kind of messages in the command window.
No mistaches !!
I tried with my last bootloader and recovery came from the ....013..GEN1 .. (sorry I'm writing from my office so I don't have all params .. )
And here, miracle !!!! I had the famous message above the Acer logo : "P A S S" ...
After that I used the EUU software and flashed my tab... switched off
switched on and here's the HoneyComb !!!!!
next step I have to upgrade it into ICS .. but I think it would easier (any easy method, EUU or Acer application or anything else) .. I hope ...
thank for your help again
see you

See cpuid guide in my Sig there are 8 methods to retrieve it. Any nandroid backup stores in a txt file in the backup folder.
Not having volume button is gonna add to yr probs if apxflash cannot boot u to apx mode and get u yr cpuid.
If u have the unlocked boot loader you can hook up to yr pc and use fastboot to get u into recovery. Once yr tab is running again install a reboot app or flash a cm Rom which has reboot options in the shutdown menu.

Ok. Thank-you very much! I was actually able to find it in an archive (I had written it down in the past, but couldn't find the file) Making lots of backups this time.

Hi Dibb,
Of course, if I hold the power button, my tab switches off.
But, now I have again the trouble.
As I told in my last post, I succeeded to install the EUU software and have the HC 3.0.1.
But I did the official updates by ICONIA TAB Update Enhancement from the 1.016.05-COM-GEN1 to the 7.014.01-COM-GEN1 (HC 3.2.1) without troubles. At this step no more official update.
I updated the ICONIA TAB Update Enhancement, and it found me a new one : 041.203.01-COM-GEN1 (I thought it was the ICS one), so I did it.
And my troubles came back !!!
My tab stucks on the ACER logo page. So I tried to update the bootloader. Since this moment I can't anymore launch the nvflash.exe. Each time, with any bootloader I have some error logs after creating partitions :
Either : formatting partition 2 bct please wait.. failed
or : bootloader status fatal failure to read / write to mass storage (code 9)
How can I do to downgrade to HC and install it again ?
Any precision : I tried APX Flash and AfterOTA without success ....
Thx a lot

The Update enhancement tab IS ONLY FOR upgrading FROM HC to ICS. THe bootloaders are very different between HC and ICS, so, once you are on ICS you sorta have to stay there. you cannot flash an HC rom from ICS, you need to do a downgrade.
Either, do a full downgrade back to 1.016.05 it should give you an update straight away to 4.xxx.xx, if not just flash the v8 unlocked bootloader from there, unless you want Acer Stock ICS
AfterOTA won't work unless you have completed the full OTA update process.
ApxFlash tool is the only tool that repairs bct error, its not very good at it once you have received that error as I posted earlier -

[Q] A500 After reboot, always stuck in APX

I've searched, but I don't see anything quite like this issue.
I was handed a dead Acer A500. Found it was stuck in APX mode (black screen.) Ok, that I can deal with.
Found my CPUID, and SBK, flashed it back to factory using Blackthund3r's Flash utility, got it into Android HC, Great.
Well thought I should restarted it and make sure it's good everytime, nope... After a power down it always goes back into APX mode (black screen.)
I've run Babsector
And get:

I can flash TWRP 2.6.00 to it and get it to boot into that if I don't power off.
Just EVERYTIME I power down, it looses everything and goes into APX (black screen) and I have to flash it to get it up again.
Any Suggestions or pointers?
Thanks

Two things...
1.
According to the babsector output, it's using an hc boot loader, It's a bit weird actually as babsector flashes skrilax_cz patched boot loader, not hc???? so not sure how you got that....
2.
your tab is waiting for you to put it into apx mode...Once done, press any key to continue...from memory, your tab will vibrate and boot into 'bootloader mode'...it will display 'Acer a500 download mode' so it can flash recovery and BL.
Boot directly to recovery, do a full data/cache format and flash your chosen ics rom.
I'd also be tempted to run the b.bat file after this since you've had issues and even another wipe to be safe...then
you should be good to boot to your new rom!!

It's not that I don't have a problem loading a different rom, it's that when I restart the device it goes into APX again. So I flash it, and again back into APX after a restart.
Does that make sense? Or did I miss a point?
I've put TWRP on, and flashed a update.zip ICS version (from here: hxxp://forum.xda-developers.com/showthread.php?t=2049778 ) also and after TWRP restart's it goes back into APX.
I can Use Blackthund3r's Flash tool and this: EUUs_SBK_Acer_A500_1.016.05_COM_GEN1.a500apx and get it to boot after flash, but as soon as I restart the device, back to APX.

Looks like you didn't fully run babsector
here are some notes from the procedure
2. put tab in apx by holding reset (small pinhole bottom right side)
and pushing power for 3-4 sec. - then release reset approx 1 sec. later
the screen should be blank and power button should be lit - plug in usb to pc.
2. Run a501 A.bat
3. run recovery ->WIPE -> "Advanced wipe ->System (only)and swipe to wipe.
4. Run a501 B.bat
reboot to recovery and install rom and gapps

1. Can u fully run babsector/nvflash without getting stuck waiting for "bootloader mode"?
2. The output you posted clearly shows hc bootloader. You
cannot flash any ics+ rom without skrilax_cz b/l.
3. The euu u flashed is hc. So you're sorta going round in circles.
get the patched bootloader on there using babsector. If your tab is stuck on apx mode (black screen, led on) power off then manually put your tab in apx mode and ' press any key', if you don't see download mode displayed on screen then we have a problem here.
If you do get download mode then after the flash, boot to recovery and do the wipes and flash your Rom.
You must do things in this specific order and as posted, the Acer is a finnicky beast that will throw a hissy fit and do things like get stuck in apx mode - why? b/c the nvflash operation has not completed properly and it's trying to tell you that... but your first priority is the patched bootloader...

The screen shows PASS, and no longer showing in device manager.
After this I power off the device and power it back up to a BLACK Display, My computer shows it in device manager: "Acer USB Boot-recovery driver"
Am I missing a step between that and restarting it?
And Thanks for the help so far.

Sorry been awhile since I've done this...after PASS, power down and boot straight to recovery, wipe, flash Rom.
Power down. Connect to pc, manually enter apx. run b.bat. power Down, enter recovery wipe data and caches, don't wipe system this time else you'll wipe the ics Rom you flashed.
Reboot.
You should see skrilax_cz bootloader screen on boot, fingers crossed!

This is where it doesn't happen. I try to boot into recovery, but I get nothing but a black screen.
What I do:
Turn off the tablet.
Hold the volume down key (the part of the volume rocker, which is closer to the edge of the tablet) + power key.
The tablet should boot in the recovery mode, but I get a black screen and the computer (connected via usb to the tablet) shows I'm in Acer USB Boot-recovery driver.
nothing on the tablet. Weird, I couldn't find anything else like this on the forums.

K if its not booting to recovery the flash isn't working for some reason. The drivers look right...
Try booting to fastboot pwr+vol UP..should see skrilax_cz bootloader menu..

Disconnect from your pc after PASS..press and hold power button until the led goes off then try recovery....you'll need to pwr down like this for before entering apx mode too, don't rely on fact your tab is in apx mode b/c the screen is black and the led is lit...I'm sure it should vibrate when it's in apx.
Sent from my HTC_PN071 using Tapatalk

Disconnected usb after pass, power off by holding power up to 4 seconds, waited a few seconds. Verified off by removing power.
Powered back on, White light on the power button, and no display.
Tried powering off, Vol + and power= no change, Vol - and power=No change.
Plugged it into the pc, and I get the ACER USB Boot-Recovery Driver, but no display.

Not that I think this has any bearing but what do you mean pls?? The tab is powered down when the led is off.
Do you get an orange led when it's charging??
Ok, apparently there are issues with the later versions of twrp, so run babsector again to get cwm....
Remember, you have no OS on there yet, so don't try and boot until you've flashed a Rom - try this one http://forum.xda-developers.com/showthread.php?t=1935582 pls read the install instructions...
See how u go
Sent from my HTC_PN071 using Tapatalk

Meaning: power is disconnected, LED in power button shuts off. Charging light is on when it's charging and orange (currently full right now)
I'll try CWM next and follow your instructions in the 4.1.2 link. thanks

Ok so I loaded using BlackThund3r's flash utility:
Skrilax_CZ v6 bootloader, and Thor 1.7.3 recovery
When I do it that way it auto reboots into Recovery (no need to shutdown)
And I loaded that CM10-FLEX_V6Supercharged_Rev3.4.zip to a Micro SD and renamed to update.zip
Loaded it all the way through, got it to the main screen. Worked, Did a reboot=Booted
did a shutdown and then power on= Black screen and APX mode when I plugged it into the pc after not getting a vibrate.
I know the bootloader is still installed as I tried the AFTER OTA without my SBK and it processed it (Was a little shocked but happy something is sticking) If that info helps.
Tried the same thing with the v8 loader from Skrilax_CZ = same result
Anything to try next?

Flash the Rom normally, do not rename to update.zip.
AfterOta is only if you have ota'ed from hc to ics and on stock.
So I'd reflash the Rom first, then reboot to recovery and wipe data/media, you have to enable this option. Then reboot.
If still stuck,
Go to the root guide in my sig, there's a section in there re stuck in apx mode....2 things to try run the nvflash -- go command, and safely remove apx device.
if that doesn't work I'm outta suggestions, last resort you can try fastboot ...fastboot boot boot.img command, see if you can boot to the os . all the info is in that post.
Sent from my HTC_PN071 using Tapatalk

Tried all that, except the fastboot stuff, but I even tried the nvflash processes that was mentioned.
I can boot the roms, I even tried that link's "Downgrade using tdv4" And it all works to flash it, boot's the rom, and everything. I can reboot the A500 via commands, adb, and fastboot, however if I shut down the A500 or power it off it's back to black screen (nothing on the screen) with apx mode available to me when I plug in the usb to the pc.
I left it a while today while in Honeycomb and the screen would flash on for a moment with the lock screen up, then it would be gone, wait like 10 seconds and it would do it again and repeat unless I plugged in the usb to the pc, then it wouldn't ever do that.
This A500 was stock when I got it, the owner had no clue it could be rooted, or updated in anyway, just one day he turned it on and it was black so I got to play with it. It took a few weeks of research to find out how to get the SBK then be able to flash it to try to get it to recover.
Would there be something that would make it stick in APX mode after every power off?

deleted

Ok figured it out!
Did a battery pull, and the good old Press the power for 1 minute, and then plug in the battery and test.
Comes up every time now. Currently it's stock so i'm going to put CM10-FLEX_V6Supercharged_Rev3.4.zip back on.

Unbelievable!!! What made you think of doing that lol...well done for not giving up
Sent from my HTC_PN071 using Tapatalk

I wanted to open the device and at least re-eat the ribbon cables, make sure the reset button wasn't stuck or something.
Thought while it was a part there's no harm in doing your typical "laptop" power reset. (I'm a computer tech, I do it usually once a week with phones and laptops for customers)

So you just disconnected the battery or pull it out....any tips for those wanting do the same??
