@bazsh.....This is only a thought for you to consider. You say you are using Honeylicious which was a specialised ROM designed, developed and published by an Iconia developer who used the name kjy2010. If you are using this ROM it implies that you have installed a specialised "Recovery" such as CWM by ClockWorkyMod or TWRP by TeamWin and that is how you installed Honeylicious onto your Tab. If this is the case the easiest thing to do is search the "Developer" thread until you find a "JB" ROM you would like to use.....download it onto your ext_sd then use your "Recovery" program to flash it to your Tab. My own personal preference is for the JB-4.1.2 ROM by "civato" but to each his own. Don't forget to read the installation instructions regarding what to "wipe" before you flash.

It's an HC Rom so flashing via recovery won't work until you've installed the patched bootloader. i.e skrilax_cz v8+ ... Doing the wipes is imperative as @metpolds said.....as is the CPUID.
Guides are in my Sig.

Thanks for ur reply
Yes I am using kjy2010 ROM
But he stopped developing new custom ROM for quite some time
After he quit I've tried to search the method to upgrade but it seems quite difficult for me coz im quite noob
Anyway what is the proper method that i can use so that i can install civato's ROM
It's good if u can give me an outline what to
I'll try to read on each thread after that
Tq
@dibb_nz..... Many thanks for bringing up the important point I forgot.....the bootloader!! I have been using skrilax_cz's v8 for so long now that I completely forgot about it.(face/slap)

@bazsh.... @dibb_nz can answer your questions better than I, but look at the attached post/link which is by @civato it will tell you how to install the new botloader, provided you can understand what he is saying.
NO insult intended.

I've read through the thread to get the CPUID
Which method is the easiest for newbie like me to proceed?
Is AfterOTA is the best method to retrieve my CPUID?
Im using Honeylicious ROM for the moment
What bootloader am I using? Supposedly HC bootloader right?
Can I just flash my tablet without getting CPUID & flash skrilax bootloader?

I already read Civato's & Skrilax thread but still confused
I've downloaded Skrilax V9 patched bootloader, CWM update, APX Flash, SBKTest
How do I flash my bootloader?
Using APX Flash or NVMflash?
And it says that it will patch ICS bootloader but am I using HC bootloader currently?
Is it safe to flash on HC bootloader?
OMG...too many jargon words for me
Any experts please help

Use manual nvFlash it's best since yr tab is not booting.
Yes it's ok to flash from HC b/l.
The jargon side is a bit tuff but u just need to do take one step at a time. Don't be in a rush and you'll be fine. If something doesn't seem to be working then STOP. Don't carry on. Or hope it will be ok. Just come back here and ask.
The sbk test is a good start, if that runs ok then u shouldn't have any probs with the actual b/l flash!!
Good luck!!

Becoz there are 2 sets of drivers required. One for 'browsing tablet memory' and the apx driver for 'nvflash' to work
This is why the cmd window never popped up with sbk test.
So u have a driver issue to solve.
Which OS is yr pc running, 64bit and win8 are dodgy. Win7 an xp are best.
You won't get any further till u get this sorted.
There's a mini guide for correct driver installation in the first post of the cpuid guide, near the bottom.
Stick with the manual method, it's easier for us to pin your issues.
May pay to check out my root guide too if u want mo're detail than civato's guide. There are no problems you will face that have not been solved here many times over.
As I said b4, take things slowly and one step at a time. We don't want to end up talking u thru how to unbrick!!

if sbk test has given you the cpuid, then use the manual flash method now, just run the v8.bat file and you'll be done.

v8 or v9, doesn't matter. Once you've run the bat file THEN
boot direct to recovery, complete the wipe procedure and then
flash you ics or jb rom (you should have this on your ext sd card now, ready to go)
The v8/9 flash will take 2-3 mins at most.

Hi guys welcome to the weird and wonderful world of the acer tab!!!!
Things are very different with this device, whats 'normal' for other android devices is not 'normal' for our tab!!!!
So first of all, dont try installing cwm or a rom the 'normal-this-is-the-way-I-did--it-on-myphone', you will end up with a brick!!!
2nd, you both have working systems at present, so we'll try to keep it that way.
Open up a file explorer and navigate to this:
/sys/firmware/fuse/acer_cpuid
One of the first things that are different is this: acer_cpuid
It should look something like this:
288424344009597 - now u need to add a 'zero' to the front:
0288424344009597 - this is your cpuid, back it up in multiple places if need be, just dont ever lose it - IF anything 'goes wrong' at any time you will NEED this number to save your tab from eternal brickdom!!
3rd once you do get your 'cpuid' go to the 'sbk generator' here.
This generates your 'sbk' or secure boot key and will give you something like this:
0x93588800 0x33CE8901 0x0BED6D03 0x30737899.....
OK then, now you have your cpuid/sbk you can start thinkning about what rom you want to install on your tab.......
Read the OP(Original Post) of your desired rom. This will tell you EVERYTHING you need in order to flash it - remembering always that 'Acer' does not do things the 'normal' way!!!!!!
Most of the custom ICS/JB roms on here all require the 'patched / unlocked bootloader'... In fact, even installing a custom recovery, cwm, twrp or public recovery, for the first time....will require the BL to be 'patched' first....and yes, even flashing this is not done the 'normal' way....tho the process can be complicated there are PLENTY of guides and auto tools to make it easier for you....
The 'patched bootloader flash' will also include a 'custom recovery' too, and you can choose from 3-4 options....amazing but i'd advise to use cwm 1.7.3, until u get up and running, after that you can go crazy flashing anything you like!!
So basically there are 5 main steps to getting a custom rom installed.
1. Install the Acer Drivers and the android_sdk drivers
2. Get your cpuid and generate your 'sbk'
3. Your desired rom is on your external sd card
4. Put your tab in 'apx mode' which allows u access to download mode
5. Install the patched v8 bootloader/recovery - either manually using nvFlash or using the auto tools.
Personally I prefer the manual nvFlash method, if you get an error it will at least give you an error message...the auto tools will just get 'stuck'
Check the 'bootloader' thread OP for a guide to manual nvFlash and the patched bootloader package here
There is also a step-by-step in my sig!!!
If you want to use the auto tools then apxFlash tool, or afterOTA tool you can find both in the 'bootloader' thread. And a step by step for apxflash tool also in my sig....or this excellent one here by user jdgM3NT4L here...
please be sure to read these posts very carefully and if there is something you do not understand then please dont hesitate to ask , there are plenty on here who will help you thru the process....AND its easier to offer help at this point rather than trying to do so when you've bricked it.....
As far as roms are concerned, you cant go past 'civato's FLEX roms' very stable and no issues i'm on cm10 and havent had a problem with it.....Of course it depends on what you require but I'd start with one of the flex ones.
Most peeps here have no trouble with this process, those that do, usually try things the 'normal' way, then find out they need their cpuid/sbk to get out of trouble and of course they dont have it....this makes things most difficult.... there are a few tabs with motherboard issues that have needed to be sent to acer....other than that, he only other issue you may have are driver related, check out the cpuid thread for anything driver related and lots of other background info too....theres also a zip file there that has a mini-sdk kit, to save u downloading the full android-sdk....
i think thats all i can think of at the moment, sorry for the long post and all the caps and bold text - just trying to save you alot of unnecessary grief...
Good luck with it all and remember....in this forum things are not 'normal' :laugh::laugh:
Wow, a lot of stuff to do just to flash a from huh. Lol
Sent from my A500 using xda app-developers app
Lol, as always preparation determines the success of the final outcome....and yeah with the tab 95% of yr time and energy is spent preparing!!! The actual flashing process takes only a few minutes...
Of course u could revert to hc 3.1 where everything is 'normal' i.e. one click root, flash cwm, flash rom, done....
Gosh, even hc 3.2 was locked down and unrootable....
So in the grand scheme for us to even be able to have stable ICS roms, let alone cm10 on the a50x.is.purely down to those wonderfully clever devs we have here..who were never gonna let a.locked bl, get in their way..
OK its complex I'll admit, but stock ICS is c**p and the lives of our tabs extended past wot Acer ever thought....and guys like gersma and.blackthund3r have built auto tools to make things easier
Anyways, its.well worth the
effort and is actually alot simpler to do than it is to describe how to do it...think of.trying to explain how to ride a bike and writing all those steps out....much easier to help them thru it by just getting them on the darn thing and doing it....dontcha think??

Oh, one other thing, you'll wanna back up all yr personal stuff, music, photo's and wot not especially going from one build to another, and most of the custom ROMs require a complete wipe and format of yr data partition too before install, just so u know!!

wow dibb, thank you so much for a helpful response!! Really enlightened me about how far off I was about the update process (compared to updating phones) and yet close enough to what I had to go thru for the Viewsonic GTab.
I'm currently on stock 4.0.3 rooted for A500. I have obtained my cpuid and SBK. When I go to recovery mode, I see a droid with triangle and exclamation mark. I tried flashing twrp but I still saw the same droid. I now know that I need to flash a different bootloader with recovery included.
My question is that if I flash the new bootloader which will allow me to put a custom recovery, during that process will my current ROM be removed or wiped out? If so, what do you recommend for backing up the app in the current stock ROM? Titanium Backup? BTW, I don't have an external SD card; all I'm using is the internal 8GB
Thank you for your help!!

Yes u need the v8 bootloader to get a recovery installed...
Always check the original post of the rom you install for special instructions regarding bootloaders.....this applies to all custom Roms even stock pre rooted ones.
Yup TB to back up yr apps and data - dont restore immediately...make sure everything is stable first.
If u dont have an ext. SD card, the EUU method doesn't require one, and as slayinu said, it would make it easier if u had one especially for the update.zip methid
Im sorry...

Seems weird afterota "doesn't do anything"...did you install the drivers?? Did it give u yr cpuid/sbk you cannot do anything without this AND if u muck things up its the only thing that will get u unbricked? Are u using a micro USB cable? Do u have USB debug enabled?
If u go to the root guide in my sig you'll find d.load links and all the guides to help u install the v8....take special note of the boot.p file u need to rename or delete in /system....
For more info on getting yr cpuid/sbk see the cpuid guide in my SIG or the sticky in dev forum...

I'm too dumb to figure this out...idk how to get my cpuid none of the ways in your "where's my cpuid"guide worked.I don't want to stay stuck on ota 4.0.3 but apparently I have to..thanks for your time and your advice,unfortunately I wasn't able to use it properly.
Well, it seems it's not just you being dumb ...
I tried the same - original OTA 4.0.3 and rooted my A500. Now tried to use the 'AfterOTA'-Tools, but getting stuck in step 3 of 4 (maybe i just need to insert a SD-Card in the Tab?).
Just got no idea, what to do now - the only thing i know is: before flashing, i need a open bootloader, but i've got no idea how to do that. The Guide linked in this posts: http://forum.xda-developers.com/showthread.php?t=1622425 is just confusing me more and more
After a reading a few times, it seems to me, that MY next step should be:
"Automated flashing tool" (STEP 5= Going into APX mode see Q&A or use A500 manager)
-1-Reboot your tablet and make sure on your tablet: "Settings" -> "Applications" -> "Development" -> "USB debugging" switch on.
[...]
-It will ask if you are ready (click yes if you are)

Hi voodoo, no, neither of you are being dumb!!! It CAN be a complicated procedure, we try to make our guides 'simple' but theres ALOT that can go wrong
Yes the last link you posted will flash the patched bootloader!!!
- but basically this is what SHOULD happen
Note: The only way to get a custom ICS rom on your tab is with the v8 bootloader by skrilx_cz. This must be flashed via nvFlash/apx mode.
Note:The only way to install a custom recovery like cwm or twrp etc is with v8 bootloader.
Note: You cannot use Acer Recovery Installer unless you have the v8 installed.
Note: Rom Manager does not support our Acer Tabs...please don't use it to flash 'anything'!!
OK heres an overall view of the process:
1. Install Acer and adb/fastboot drivers
2. Retrieve your CPUID...
3. ...and use it to generate your SBK
4. Download your ICS or JB rom and copy to your sd card (internal or external)
5. Enter apx mode to begin the flash!!! or use apxFlash tool
5. Use balckthund3rs apxFlash tool and follow the instructions: hint: dump and save your bct!!!
5. If using civato's manual nvFlash method - Put your tab in apx mode and run the .bat file
5. AfterOTA Tool is only for those tabs which have OTA'ed to ICS!!!
The main issues you will have with the actual flashing process itself is a partitioning error or a bct error - and both of these are easily fixed...UNLESS your tab in one of the few with a hardware fault which only a new motherboard can remedy
Once you get the big white "PASS" on your tab, boot straight to your new custom recovery, do the FULL WIPES and flash your new rom....DONE!!!
Well ... i now used AfterOTA - but not in a virtual machine - now just natively installed on my macbook via bootcamp (windows). Worked. I now have a V8-Bootloader (the tab shows me this when iam booting it up).
Whats the next step to flash a new ROM? Iam ready to do that? Or is there any other step needed by now?
Regards, Tom
Edit:
I now just tried flashing a custom rom - so i copied the *.zip to my USB-Stick (FAT32) - because i read, i can use an USB-Stick as an micro-sd card.
Tried booting into recovery-kernel - worked for me, but the only thing i can see: a lying android with an red sign ("!").
Did i something wrong?
Oh dear....if u had a stock rom on there then its overwritten
your newly flashed recovery....you need to delete or rename
the "boot.p file" in /system..then reflash the v8...
The very next step should be to enter recovery and flash your
desired rom....
So, it now just works everything.
Used Acer Recovery-Manager to re-flash the recovery - worked fine for me.
But: i tried several 4.1 and 4.2-ROMS ... is it correct, that there's no Google Marketplace anymore on 4.1 and 4.2?
I was trying to flash my A500 back to stock and something, somewhere, went horribly wrong.
I did everything I normally would: factory reset, wiped cash and dalvik, and then flashed the ICS stock zip. I rebooted the tablet and it said something about updating the bootloader and then went black. Now, the black screen is all I can get.
I've got good drivers on my Win8 computer, and the device is recognized in APX mode, but I haven't been able to do anything with it. I've tried messing around with A500Manager, AfterOTA, and the APX Flash Tool, but I do NOT know my CPUID - which makes everything quite difficult.
I looked through the thread about getting the CPUID from the tablet via USB while in APX mode, but I know nothing about coding or building drivers and the like, and it all went well over my head.
I don't normally ask for help like this, (as one could guess from my post count) as I very rarely find myself in a situation a good amount of reading won't get me out of. This one has me well and stuck though! Any help would be greatly appreciated!
(For the record, I was on the unlocked V8 bootloader, Thor's CWM, and CM10 and tried flashing Acer_A500_1.041.00_WW_CUS1)

Hi Clark, sorry to hear of yr troubles....there's a recent thread here that sort of describes your issue....I'll post a link in a tick
But what happens when u turn the tab off - make sure pwr led lite is off - and then power on again?
Can u charge yr tab - pwr led is orange?
Flashing stock - did u use an update.zip or EUU or flash via cwm - there's a great guide how to revert to stock the easy way by jdgM3NT4L u should look at.
You might try booting to fast boot pwr volume UP but it sounds like that may not be available as u said yr tab did say updating boot loader...
Once u have the v8 boot loader the ONLY way to revert to stock is a downgrade to HC
Try running the nvFlash manually see civatos boot loader guide, (this requires yr tab to be in apx mode first,) and run the bat file.
IF YR TAB DOES NOT ENTER BOOTLOADER/A500 APX MODE please disconnect everything and don't go any further - you'll end up in more strife!!!
I'm on my way to work so will post links when I get there....

Thanks for the response!
I flashed a .zip via CWM to attempt to revert to stock. I flashed an ICS stock ROM (Acer_A500_1.041.00_WW_CUS1), while on the V8 bootloader, might that have caused my problem?
Right now I can only get the tab to do two things: charge and boot into APX mode. No matter what else I do I just end up in a black-screen APX mode. Power+Vol does not do anything other than put me back in a black screen with power LED white state.
I haven't tried doing an nvFlash yet - can I do that without my CPUID?

most definitely....u must flash a stock update.zip....but an EUU is best
u cannot flash ANY ics rom like this UNLESS u have the unlocked bootloader first... and u must downgrade If wanting to revert to stock....

no u can't but if u did have the v8 u must have had yr cpuid....you'll need to find it, u cant do anything now till u get it,
just becoz i wish to spend some quality time here on xda....we are flat.out at work, lol....
u can try theauto flash tools.but. they
rely on the cpuid....there's a guide.in my sig but the.only option u have is eppeP.s method, check.out srbeens guide there..

If your tab has been connected to your pc, you can get the cpuid from your pc, without the tab connected. (using USBDeview)

Well,there is still Linux. Not a Linux guy, but search the forums, you can find instructions for running some linux commands that will find your cpuid. http://forum.xda-developers.com/showthread.php?t=1751978 is a good place to start.

Fantastic! I've got a laptop running Ubuntu and I'm pretty comfortable with being a script-monkey in terminal, I'll give it a whirl when I get the chance to spend some quality time with the tab.
Thanks for the link too, I had not found that one before. I had seen eppeP's guide and it made my head spin pretty quick, the srbeen one you linked to looks like someone with no dev experience like myself might be able to pull it off.
*fingers crossed*

HAAAA!!!! Success!
Well, I had some trouble with my linux laptop being 32-bit and spitting out the wrong UID, but got that sorted and snagged my UID and SBK.
Used blackthund3r's APX Flash Tool to get the V8 bootloader and Thor's CWM back, and then flashed rooted stock - all is good!
Not sure if I'll try getting back to full stock or not, still deciding if I want to sell the tab or give it away as a Christmas present.
Thanks so much for the help everyone!

I could, but I'd be pretty much just replicating srbeen's thread here: http://forum.xda-developers.com/showthread.php?t=1751978
The only thing I could really note is that eppeP's code that's linked to in srbeen's OP will only work on a 64-bit install of Linux. If you're running a 32-bit system (like I was) you need to scroll a bit further down the 1st page and grab the proper code for a 32-bit script.

Ok, here is what i have , I have a IConia a500 rooted with, link for forum and files, using ICS Root
(came with 3.1, ran all the iconia updates, to 4.0)
everything went fine, now... i am familiar with flashing roms, i have had a few android phones and have rooted them, and flashed custom roms on them. that is what i want to do with this, after doing over 4 hrs of reading, I have confused the crap out of myself. there is a lot of talk about things that i dont know much about..
-CPUID's
-ICS recoverys (bootloaders?)
Basically, all i want to do is add the CM Jelly time mod, but im not 100% on how i go abouts that? what do i need? i have the files and gapps, etc., i know i need a full wipe, but what recovery do i use? CWM? do i temp flash it or, pernament? after watching a few videos, i still dont think im ready, i diont want to brick this thing. i just want it to work with that rom. thanks any help and clarity is severly appriciated!

1. get yr cpuid and save it multiple places open a file explorer and go to /sys/firmware/fuse/acer_cpuid
2. then go to /system and rename/delete recovery-from-boot.p file - this will prevent your custom recovery being overwritten with the stock recovery.
3. have your custom rom on yr ext SD card, ready to flash ONCE you've flashed the unlocked bootloader
4.To flash the v8 bootloader you need to use nvFlash and there are a couple ways if going about that...
a) manually by using the guide in the OP of civato's BL thread
b) using one of the auto tools like afterOTA or apxFlash - links also in that same post...
c) you'll also get to pick a custom recovery and it will be flashed at the same time - cwm 1.7.3 is recommended until you're running stable
d) From yr cpuid - generate yr sbk - how to do that is in the same OP
5) once flashed, boot straight to recovery
6) Do a nandroid backup then the wipes
7) Flash the rom
8) Reboot to recovery and wipe again
9) Job Done!
notes:
Everything you need to do this is in civato's BL OP - sorry can't post the link but its stickied in the Dev Forum
the afterOTA tool,
- saves all yr uid details etc in a txt file
- flashes v3 bootloader -
- it also installs the needed drivers too
- its pretty good at what it does...
seems some are having wifi issues with jellytime but the dev is working on this
you've done the right thing by asking questions before attempting anything, wish everyone was like you...if my post isn't clear then please let me know....for those of us used to the way things work with our Acer, its hard to remember how difficult it seemed when we were new!!
good luck

ok, thanks !
i have used the afterOTA and it would let me select the recovery i wanted to boot, is this permanent or temp? right now on my phone its the cwm, but i remember on my Nexus S, they recomended just pushing it, that way it was super hard to brick.. basically i just need to know if i need to run the afterOTA tool everytime i wanna boot into recovery? thats why i like my CM 10 for my Galaxy Nexus, i can choose to boot into it,
I think the hardest part of these simple tasks, is that there a 20 steps to something totally new, I used to unlock iphones for a living, I never knew what i was doing exactly, i had a rough idea, but i did know how to cut and paste. even going from my NS to GN its always been a few hrs to root/unlock, Being familiar with a lot of the steps, theres more with this tablet! EI, CPUID, APX? tons of warnings! the other things are the abriviations, they can be confusing.. soo
this is the only thing i didnt understand, does the OP dumb it down, or can you??
d) From yr cpuid - generate yr sbk - how to do that is in the same OP
what is sbk, and why do i need it?

no m8, once you've 'flashed' via the tools its permanent -
there are flashable zips around (for recovery) but again, you need the unlocked bootloader first....once you have it then you can flash anything, anyhow you like. Even Acer Recovery Installer will work fine and you can flash a rom from there too, though that may require the paid version from memory.
the only time you will 'lose' the unlocked bootloader/recovery is if you need to rollback to HC - specifically 3.2 -

sbk = secure boot key....as you've discovered 'root' just isnt enough to flash anything...to flash anything you need nvididas nvFlash program PLUS the key to unlock the encryption which is hardwired into the ROM of the memory chip itself -(haahhhaa I think thats right) - The CPUID is unique to every tab (and this too may be hardwired into the chip as well) the sbk is a hex number based on the uid. there are a couple of generators around to do this for you, blackthund3er has one and so does vache....you've used afterOTA so this does the genration for you automatically - you can see it in the text file you saved
thanks again, i really appriciate it!

yeh back in the day before acer released ics, 'someone' got hold of a leaked ics version, and this is where alot of the work was done on unlocking the bootloader...by the time acer got round to releasing ics - we had a more stable version than they ever had
So now you're unlocked and rooted, have all your ID's backed up and done a nandroid you can quite happily flash to your hearts content!!!!:good::good::good:

standard tab choose first option...keep an eye on the status bar while its flashing..should not take longer than 10mins.
You must then boot straight to recovery and flash yr rom from yr USB key
don't have to worry bout apx mode but yr tab should display.either Acer apx mode.or Acer download.mode at stage 3 of 4 in tool status bar.
if u.muck.up you'll learn all u ever wanted.to know about apx.mode

If you have the correct update.zip you should be fine.
If you're trying to fix a brick you may need to use nvflash.

If the rom you had on there was a Stock rom you OTA'ed, then afterOTA tool is the tool to use to Update the bootloader....you are soft-bricked so none of the tools are much use to you.
Which link in the CPUID guide does not work pls, I shall fix that. Try the one in the root guide in my sig.
If you are not currently flashed to skrilax_cz unlocked bootlader, fastboot will not work.
You're really best to start at the beginning in trying to unbrick.
This means downloading everything you need BEFORE you start.
That means:
Acers website for the acer drivers.
The root guide for the adb/fastboot drivers.
A rom to flash ICS, JB or stock rooted ICS.
The babsector.rar file to unbrick you.
You need to know how to get your tab in apx mode manually.
You also need to run the flash manually. Use the babsector file for that and post any errors you get.
Read thru the root guide in my sig, and make sure you have some understanding of what you're about to do. It makes it a lot easier to have all your files downloaded. The actual flashing process takes about 5 mins.
The babsector file will reset your tabs partitions, flash a recovery so you can do the formats and wipes before flashing your rom. Also installs the v8 unlocked bootloader.

The link under DRIVERS: Acer Support for Acer APX/Fastboot/Recovery Drivers. Just loads a Acer error page. I get the same error page when using the link in [GUIDE][ICS] Beginners Guide - Rooting, Flashing, Unbricking.
I downloaded the OTA tool to get my CUPID, tried blackthund3r A500 manager but I need BUSYBOX installed. What would be the easiest way to get my CUPID?
About 3 months ago I bought a manufacturer refurbished motherboard from the States (I'm in Australia) had my local PC shop install it, been working great. The other night it froze & I turned it off & then back on & its won't boot past the acer screen. It's stock, I haven't modified it in any way.
i have iconia a200 got brick
I think I'm having issue with the adb and fast boot drivers..not sure it they are installed. My tab only boots into apx mode. It will launch to bootloader mode while trying any of the tools. .but hands mid way. Doesn't seem the tools see it correctly because no atx devices are detected. The acer picassa driver goes I'm because I see the tab pop up. .but not sure the other drivers are right. So I'm stuck.

The serial number you refer to, is not the CPUID number. Using USB Deview, it should have an entry for Acer Iconia A500 then about 15 or 16 numbers and letters. This is your CPUID number.
Also, if the tablet is bricked, none of the easy programs will get the UID number. So you will have to use Linux to get it. Here's a guide;
http://forum.xda-developers.com/showthread.php?t=1751978
After that, then you can roll back to one of the earlier versions of Android (EUUS) This will get you back to a 3.2.1 version.
Question, can you boot into the factory recovery? (Vol- then press and hold PWR) should see some text in the upper left hand corner. If you can, you may be able to run one of the Full Update Files from this thread;
http://forum.xda-developers.com/showthread.php?t=2755126
Instructions are there.

As with the option to dual boot kernels, I believe the theory was allowing a user to have 2 different kernels. One for long battery life, and perhaps the other for games. I think probably the long term goal, was to be able to boot to 2 different Roms, but the 500 is an old tablet, and so not much new development on the bootloader.
I will say skirlax_cz did a remarkable job on development.
Personally, despite it's age, the A500 and 501 tablets are almost brick proof. With all the knowledge and tools we have for it.
As for going back to stock, you may just install a factory ROM, like the full update for ICS. Should put it back in order.
