How to Gain Root Access by installing CWM on Xoom 3.2 Stock 3g -
***This will erase all user data.
Step 1: Install SDK, adb tools and fastboot.exe on your pc; also turn on USB debugging in settings/applications of xoom.
Step 2: Download the following files (http://www.multiupload.com/2WPUNUZYE1) and place all files into "tools" folder
Step 3: Restart your Xoom while holding the down volume button to get into fastboot mode. Plug in xoom to PC and open ADB prompt on PC
Step 4:Type ALL of the following adb commands:
fastboot oem unlock *[AGREE TO PROMPTS]
fastboot reboot
Step 5:Let restart. Again turn on USB debugging in settings/applications of xoom.
Step 6:Restart your Xoom while holding the down volume button to get into fastboot mode. Plug in xoom to PC and open ADB prompt on PC.
Step 7:unzip HTJ85B_root.zip and place all files in tools folder ie
C:\android-sdk-windows\tools\boot.img,C:\android-sdk-windows\tools\system.img,C:\android-sdk-windows\tools\recovery.img
(. Type ALL of the following adb commands(ignore nandroid.md5 file):
fastboot flash boot boot.img
fastboot flash system system.img
fastboot flash recovery recovery.img
fastboot erase userdata
fastboot erase cache
fastboot oem lock
fastboot reboot
Step 8: at moto duel core screen press up vol to enter cwm. be patient. If still frozen after five minutes hold up and power to force restart.
Step 9: once you boot into cwm, mount sd card. Create a folder on the SD card called "clockworkmod/backup/" and place the entire folder ""2011-08-05.06.54.47" inside.
Step 10: format all files, wipe dev, wipe cache.
Step 11: select "restore backup" from cwm main menu. Restart system.
This actually worked for me, hopefully it works for you.
Enjoy- Good Luck! Adam Tomaino
NOTE you can probably install other roms from this point, i didn't
****UPDATE, it appears that flashing the recovery.img file is the only necessary file to flash. also I have been loosing my root on reboot of my xoom....Hummm
********UPDATE 2. I am able to get cwm loaded and flash in roms/kernals gain temp root access, but my wife wants her xoom back so factory reset it is... I will try again tomorrow.
?????
OK I am completely confused now! I attempted to do a Factory reset to get back to stock after attempting to flash tiamat and getting stuck in bootloop after bootloop at honeycombs, So after factory reset MAGIC I have custom rom, kernal, and root on 3.2. I have been able to reset without loosing root. This is all over my head but hopefully my folly will prove useful for someone who actually knows what they are doing in coming up with a real solution. As for now I HAVE ROOTZ!
You were bootlooping because you are supposed to do a complete wipe/factory reset before or after flashing the rom. Once you wiped all the old user data you were good to go...enjoy!
Please help!!
OH MAN, Im BRICKED!!!
PLEASE HELP!!!!
When I try to restart the xoom it shows:
Failed to boot LNX 0x0004
Starting RSD mode 2
And thats all.
What can I do??
repeat from step 7 on up to end and MAKE SURE you wipe cache. dev before you flash recovery/ then after recovery choose factory restore.-AT
hay I have noticed that when you use the CWR from the post you will loos root after the reboot, do everything in the tutorial but restore the CWR backup found in the third paragraph here http://www.mydroidworld.com/forums/...-update-your-3g-xoom-3-2-directions-file.html I have tested it and it works great.
Post 1: Rooting, Flashing:

Please read carefully and thoroughly all the steps before you start...if something is not clear then feel free to ask...its easy to softbrick your tab and not as easy to unbrick it...
You will need your CPUID - this cannot be said enough!!! Please do not attempt any flashing until you have a copy of it stored safely!!!
Bear in mind - installing custom roms and a recovery IS NOT DONE the same way as on your phone or other android device!!!
You must install the "skrilax_cz unlocked v8 bootloader" to install a custom rom/recovery
There is alot that can go wrong and you will need to follow the directions to the letter.
If you are stuck with the acer logo on boot or faced with a dead android or a recovery verified failed, when booting to recovery
then you have not followed the correct procedure and at the very best will need to do this all over again.
Before you go any further and while you can still boot into your tab - please retrieve your CPUID - see my guide here
Summary of Steps to flashing the skrilax_cz unlocked bootloader and custom recovery using nvFlash
Step 1. Install the Acer Drivers here and the USB drivers from the Android SDK here
Step 2. Retrieve your CPUID
then head to blackthund3rs site to generate your sbk

How To Retrieve Your CPUID
Gersma's AfterOTA Lite retrieves all your ID's and saves them to a text file get it here
From a working system in /sys/firmware/fuse/acer_cpuid
Click to expand...
Click to collapse
Step 3. If you are running factory stock - you will need to rename or delete "the boot.p file" in /system to prevent your custom recovery being overwritten
- Use blackthund3rs ICSRoot here which will rename "the boot.p file" for you
- Have your Custom Rom downloaded and copied to your External SD Card ready to install immediatelyafter flashing skrilax's patched bootloader
- You are now ready to proceed with the "installation" you will also be asked to choose a Custom Recovery (CWM, TWRP,or Public)
Step 4. There are a couple of ways of doing this, manually or with one of the Auto Tools
- civato's manual nvFlash download and Guide and a walkthrough here
- Download gersma's afterOTA Tool if you have OTA'ed to ICS
- Download blackthund3rs apxFlash Tool and a walkthrough here
Step 5.To Manually Enter APX Mode
To get into APX mode, power off the tab.
Then, press the reset button (use a paper clip).
While still holding reset, hold power for 3 seconds.
Then, release power. Release reset after 1 more second.
The screen will be blank, but you are in APX mode (the power light should be on).

Once the flash is complete, boot directly to Recovery, Do a Wipe and Format and install your Rom!!

I have the unlocked bootloader: how do I update or change my recovery?
Only a few custom recovery's are compatable with ICS Custom roms, I've attached these to this post and they need to flashed via fastboot
Via Recovery:
There are some flashable zips around so copy the zip to your external sd or flash drive
boot to recovery and choose:
Install from zip option
Navigate to the zip and flash!!
Via fastboot see Post 3 for using fastboot
Use Acer Recovery Installer from the playstore
Please note again this is only possible with the unlocked bootloader
I'm on a stock rom, How do I root, I don't want a custom rom or recovery?
If you're happy with Acers Stock Rom?? and just want root, there are a couple of options:
blackthund3rs icsRoot.zip in Step 3 above - extract and run the .exe...Done

When Things Go Bad....How to unbrick
Download Links to Unbrick your Tab
1. update.zip method using HC 3.1_Full_Update.zip
Notes on use:
- rename the zip to "update.zip" and flash either using cwm or "pwr/volume down"
- you can flash the v8 bootloader from HC 3.1 if you want to ---
- You can restore a nandroid backup or flash an HC rom from here too, first you need to rootby installing iconiaroot then flash a custom recovery using Acer Recovery Installer
- oh how easy it all was on HC 3.1
- es File Explorer download here
Use this update.zip for any of the following:
- You do not have your cpuid
- You are stuck on the "Acer" Logo
- Your tab boots past the Acer Logo but then boot loops at the boot animation
- You are on the old HC bootloader /ICS Rom combination
- You wish to return to factory stock, and OTA all the way to Stock ICS
You CANNOT use the update.zip method if:
- You are stuck in apx mode
- You have unsuccessfully nvflashed skrilax_cz unlocked bootloader or timmydeans root tool-tdv4
- You have boot verified failed error
(Please see the EUU/nvFlash Method below to repair these issues)
HC 3.1 FULL_update.zip
************************************************************
2. nvFlash/apx/EUU method
you MUST use this if:
- the update.zip has not worked for you
- you do not have an external sd_card
- flashing the unlocked bootloader has failed
- your partitions are screwed up
timmydeans root tool -tdv4- will reset partitions, and downgrades you to a pre-rooted HC3.2.1 with cwm 1.7
To Downgrade using tdv4:
1. Do not connect your tab to your pc
2. Run the tool till you see the window telling you to put yr tab in apxmode
3. Put your tab in MANUAL apx mode using the button combo
4. Connect your tab to your pc now
5. Let the tool continue - you should see the big white PASS when its done!
***********************
BABSECTOR.RAR
***********************
***********************
babsector.rar download here - will reset partitions when tdv4 will not work for some reason
How to use babsector -
Turn your tab off and put it in apx mode manually. Press and hold reset button, hold power for 3 secs after the light comes on and release it, after another second release the reset button. Your screen is black and the power light is on.
On your PC:
Download and extract the .rar to a folder on your PC
Connect your tab to your PC
Navigate to the babsector folder and click on 501 A.bat
On your tab:
Reboot into recovery power/volume DOWN - (closest end to the power button)
Go to Mounts and Storage Menu and
Format - System, Data, Flexrom, Cache
Then flash your ICS/JB rom, power off.
Go back into apx mode and run 501 B.bat
Reboot into recovery and do the wipes
Reboot!!!

3. Stuck with Black Screen and Power LED Light is on
This can happen "just like that" for no particular reason or after an OTA - if this is the case, its more than likely caused by a faulty memory chip on the motherboard - the ONLY fix for this is a replacement m/b from Acer..
Most likely though it happens by trying to flash a recovery or bootloader via Custom Recovery or a Rom Manager or Acer Recovery Installer - the first time bootloader flash must be done using nvFlash - OR if you've tried to flash BEFORE your tab has entered "Acer Download Mode" as displayed on your tabs screen
If you are using one of the auto flash tools and the tool seems to get somewhere - do not carry on -
1. use "safely remove hardware" icon in the PC system tray to eject the "APX Device"
1a. if there is no apx device listed here - then you need to install the drivers correctly then try the flash again...
2. next close the tool down and disconnect the usb cable
3. reboot both tab and PC
4. Once you;re back in windows connect your usb cable to your tab
5 Check the Acer-Picasso boot/recovery driver has installed
6. Proceed with the flash again
Getting out of APX Mode
If worse comes to worse and you are definitely stuck in APX Mode then download the archived file nvFlash.zip which will only flash the v2 unlocked bootloader - to flash a recovery image you'll need to download one and copy it to the nvflash folder.
1) extract "nvFlash" to C:\nvflash
2) pwr your tab OFF and ensure the Pwr LED lite is off
3) Manually put your tab in APX Mode
4) Connect your micro usb cable to your PC
5) Ensure your PC lists an "apx device"
6) Open a command prompt on C:\nvflash
7) Follow the steps below from vache:
vache said:
launch this to load bootloader :
Code:
nvflash --bct bct.bct --setbct --bl bootloader.bin --configfile flash.cfg --odmdata 0x300d8011 --sbk [B]MYSKB[/B] --sync
Of course, change MYSBK with yours.
Next, flash the bootloader :
Code:
nvflash -r --format_partition 4
nvflash -r --download 4 bootloader.bin
If you want to flash a recovery :
Code:
nvflash -r --format_partition 6
nvflash -r --download 6 myrecovery.img
or a new boot :
Code:
nvflash -r --format_partition 7
nvflash -r --download 6 myboot.img
To leave APX mode :
Code:
nvflash -r --go

How to use fastboot
Fastboot works the same as adb by issuing commands from your PC
1. Put your tab in Fastboot Mode - Hold down the Volume UP button and press power button until your tab vibrates
2. Choose fastboot mode from the menu
3. Hook your tab to your PC
4. On your PC navigate to the folder where fastboot.exe/adb.exe are located
5. Open a command prompt on this folder
Run the following commands
Code:
fastboot devices
it should return a ?
To perform a Hard Reset or FULL WIPE your device
then type in:
Code:
fastboot erase userdata
fastboot erase cache
fastboot reboot
To flash a "recovery.img"
You'll need an actual recovery.img for this one, I've attached a couple to this post
These can be found in the unlocked bootloader packages
Copy "name_of_your_new_recovery.img" to your fastboot/adb folder
Hook up your PC and on your tab enter fastboot mode
Issue these commands"
Code:
fastboot devices
it should return a ?
Code:
fastboot flash recovery name_of_your_new_recovery.img
should say Done
Code:
fastboot reboot
quickly hold in the volume down button while it reboots - if you time it right it should boot to recovery...otherwise just power it down then try again

Hi
I have my A500 rooted. I DO have my CPUID and SBK
When I tried to flash unlocked bootloader with Blackthund3rs' program, it stucked on Stage 2.
I think I did the Babsector
Run a501 A.bat, but unable to Run a501 B. (unable to get in to APX mode for some reason)
then I used afterOTA (standard method)
Somehow I got the CWM Recovery 1.7.3 on the tab, some Error message when I am in the Recovery.
When I do the wipe and format following this: (from TegraOwner site)
"here's how to:
go to in recovery enter "Backup and Restore" and click on "Toggle backup and restore of internal storage (/data/media)"
should say enabled....
then go into "Mounts and Storage" and "format /data"
I get this:
Backup and Restore /data/media: Enabled
E:Can't mount /cache/recovery/log
E:Can't open /cache/recovery/log
E:Can't mount /cache/recovery/last_log
E:Can't open /cache/recovery/last_log
Formatting /data...
E:format_volume: make_extf4fs failed on /dev/block/mmcblk0p8
Error formating /data!
I am unable to flash the V170, or any other ICS ROM (encryption unsuccessful...)
Able to flash the JB V20, but only with about 60 MB left on the internal storage (I have the 8GB unit), unable to install any apps, only thing I can do is surfing internet.
The Storage under Setting shows:
Internal Storage: total space 0.00B
Micro SD CARD: total space 29.71GB
But when I press the Gallery or camera, it says No Storage, No external storage available.
Do you have any idea about what's going on with my tab? What should I do next?
Thanks

Here is what I wrote a while ago on the TO site:
I am trying to use you APX Flash tool to patch the Bootloader. (using Civato's guide on the Xda forum)
It hung at "Flashing Bootloader (EBT) stage two - uploading image..." and the other black command prompt window shows : Nvflash started [resume mode]
I, then, re-booted the A500, re-installed the Acer USB driver (used Acer link from A500 Manager)
Same as above.
Now I tried use the manual flash following Civato's guide, I got:
Nvflash started
[resume mode]
Formatting partition 4 please wait.. Command execution failed cmd 13, error 0x120002 Failed!
Command failure: format partition failed <bad command>

Any step guide on how to do this (used the adb thing before to get the SDK, I think, but forgot how now)
I had ICS OTA before, started messing with the tab few months ago, on and off, sorry I could not remember exactly how I got here.
I am not newbie totally, just know enough to be dangerous
Dibb, thank very much for your help
What I have done so far:
Step 1: Did this and my computer can detect my Acer
Step 2: I installed AfterOTA from the link provided and extracted CPUID and SBK (my question: will I be using this anywhere in my flashing process as I dont see it, if so why did I take this?)
Step 3: Since I was nervous to delete that boot.p file right away I moved that into my SD card as backup and used blackthund3rs ICSRoot to root the tablet and succeeded.
- I haven't downloaded the ROM yet as I was looking for the best in the forum, so left this step for last
- I used afterOTA to "install the unlocked bootloader" which will also "flash a Custom Recovery" as advised by you in the email (Bootloader ICS v3.14.8 + Recover Thor v1.7.3)
My big question now is on flashing the custom ROM - am I going straight away from here to recovery mode and do the below as in your thread?
------------------------------------------------------------------------------------------------
When you boot to CWM Recovery, you have a menu item "Wipes"
In Wipes;
1. Data/Factory Reset (don't worry, it skips your photos and such)
2. Cache
3. Dalvik Cache
Wait, you're not finished.
Go back to the previous menu, and select "Mounts and Storage".
1. Format System
2. Format Flexrom

How to use fastboot
@appple
1. K go up to Step 1 and d/l the android sdk drivers - (its not the whole sdk just the adb and fastboot drivers) and extract them to your C:\ drive...
2. With your tab powered off - hold the vol+ button down and press down pwr
2a. If you have the v8 bootloader your tab should display the fastboot menu
2b. Enter Fastboot Mode
3. Connect your tab to your pc with the micro usb cable
4. Open a command prompt from the folder that contains "fastboot.exe"
5. Type fastboot devices
6. It should return a "?" this is fine!
Now just enter the commands I posted earlier
7. fastboot erase userdate
8. fastboot erase cache
After you enter each command - the prompt should say 'Done'
9. fastboot reboot

afterOTA will do this behind the scenes
if u use apxFlash or nvFlash then yes you will need to enter yr sbk manually
if u need to use a rollback rom or official EUU Tool - you will need to enter your cpuid

being nervous is ok - you normally need root before you move it as its a system file...so just go back and check /system again...you can rename it "....boot.p.old" if that makes u less nervous
- I haven't downloaded the ROM yet as I was looking for the best in the forum, so left this step for last
- I used afterOTA to "install the unlocked bootloader" which will also "flash a Custom Recovery" as advised by you in the email (Bootloader ICS v3.14.8 + Recover Thor v1.7.3)

yes but I advise a Backup before you do....if anything goes awry at least you'll have that!!!
then flash your rom and reboot
As far as roms go - I've only ever used civato's ones so I'm not much help there, sorry - and I spend so much time 'bricking and unbricking' (research purposes of course!!) I don't really get alot of time just 'playing', lol...but I will say this - most of the custom roms on here are pretty damn good, they're well supported and stable....just check the last couple of pages of the rom thread itself...if theres any user issues at all, you'll find them there....oh and in the OP itself
best of luck m8!!!

Do you think I need to go and do this, as I have already rooted, and completed unlocked bootloader and recover via afterOTA, I might be renaming the one that came with the modified bootloader?

its only required if you are flashing a Stock Rom - all of the custom roms are pr-rooted and this file has already been deleted...
If the file is in /system it will remove your newly flashed custom recovery and put back the Acer Stock Recovery {i.e. dead android on its back} if this happens you just need to flash the recovery again

thats ok, we were all new to this stuff at some stage
in the recovery menu you will see an option "backup and restore"
select it and then you will see another menu - select "Full Backup" and let it do its thing...
once its done go back to the main menu and select "Flash Zip from SD Card" then choose the zip of the rom.
Just a note:
In recovery menu your SD Card refers to your external sd card
Your Internal Memory of the Tab itself is called Internal Storage

1. K go up to Step 1 and d/l the android sdk drivers - (its not the whole sdk just the adb and fastboot drivers) and extract them to your C:\ drive...
2. With your tab powered off - hold the vol+ button down and press down pwr
2a. If you have the v8 bootloader your tab should display the fastboot menu
2b. Enter Fastboot Mode
3. Connect your tab to your pc with the micro usb cable
4. Open a command prompt from the folder that contains "fastboot.exe"
5. Type fastboot devices
6. It should return a "?" this is fine!
Now just enter the commands I posted earlier
7. fastboot erase userdate
8. fastboot erase cache
After you enter each command - the prompt should say 'Done'
9. fastboot reboot

sorry i'm not too familiar with this tool - I've never had to use it as timmydeans v4 has always worked for me...
From what I can gather, running the 1st bat files uses a different partition to flash cwm 1.7.3 so you can enter recovery and perform a format of /system.
In other words it seems 'resetting the partitions' (like timmydeans tool does) is not enough - you must then do a format of the system partition thru cwm and then run the b.bat to put the original partition table back on yr tab....
You will need to flash a rom directly after using it....formatting system will leave you without an OS but this is not mentioned in anything I've read - you can read more about it here
EDIT: found a good thread for you to read here explains how to use babsector
BTW i'm working the next 3 days so may not be around as much as i'd like....

N00b trying to upgrade to ICS.
I have a acer iconia a501, There is no ics update here in Canada I believe. It currently has unrooted HC 3.2 kernal 2.6.36.3+ with a build number of Acer_A501_4.452.01_PA_ROG. some of the guides seem pretty long to me. I have tried to install android sdk, however it does not seem to function under windows 8. is there another way to do this?
Go to the bottom of this post and download adb_fast.zip - this is a mini sdk kit with just the drivers - you do have the acer drivers as well, yes?
there have been a couple of issues reported using win8, so try a different micro usb cable and a different usb port on your pc...the acer is very picky when it comes to cables...
If you have access to a linux machine you'll have no probs at all flashing the v8 bootloader
Thank you
Thank you Dibb for responding to me in the other thread. I've got the update downloaded from your post 2 and I have an external SD card to load it onto. Am I correct in thinking there's no connection required between my computer and tablet? I rename the file to update.zip, load it onto the SD card, put that in the tablet and use the power/volume- buttons correct?
Yeh u got it....I think the update.zip is good to go just copy it to yr ext sd. Best to do full wipe too m8 via Android settings...you'll be back to full stock so no custom anything....If it's the 3.1 zip u can take the ota to ics or flash the v8 unlocked bootloader from there, to get cwm...and a custom rom

Yes I am a noob, but a noob in need of help.
I recently decided to root my Acer Iconia a500 16gb WIFI version, running on stock ICS. I realised i had to unlock my bootloader to install CWM etc. So I followed a tutorial, and used blackthund3rs A500 APX Flash Utility v0.4. I used the flash package "Skrilax_CZ's bootloader V8".
So I thought all was going well, however when rebooting it, it just sits on "Skrilax_CZ's bootloader V8: Booting primary kernel image". I'm assuming its bricked, as it doesn't go beyond this point. I can get a few other options by doing the "PWR+VOL" combination and it opens boot-menu mode with the options:
-Reboot
-Fastboot Mode
-Boot Primary Kernel Image
-Boot Secondary Kernel Image
-Boot Recovery
-Set Boot secondary Kernel Image
-Set debug mode off/on
-Wipe Cache
The only option that does the slytest thing is putting it in fastboot mode. When putting it in this mode, it registers in "A500MANAGER" (when connected to my pc via USB) as the device being in fastboot mode. But I dont know what to do from there.
I've looked at multiple threads and cant find anything to fix this problem.
Please Help! Thanks!

Sounds like the A500 manager didn't do something right. Happens sometimes.
Here is what I would do. I assume you don't have the Android SDK installed. No need to, as some of the bootloader/CWM packages have the necessary files needed.
1. Boot to the bootloader, select the option "Fastboot Mode"
2. Make sure you have downloaded to PC a CWM package for ICS/JB. Usually the manual packages have the necessary files, such as the CWM image, fastboot.exe, adb, and some dll files. Unzip them to your PC. (Also helps to download a custom ICS or CM10 rom to your sd card first)
3. Open a command window in the same folder you have the files.
4. type "fastboot flash recovery xxxxxxxx.img" (xxxxxxxx is name of cwm recovery img file, do not put the " in) then hit enter.
5. After completion, immediately boot tablet into recovery. I believe holding Vol- and PWR does this. Or, Vol+ and PWR boots to the bootloader menu. Either way.
In recovery, do your wipes and or formats as per ROM installation instructions.
Install ROM
Enjoy. If you have problems locating one of those packages, give a shout back.
MD
Thanks for the fast reply,
I am a noob, so could you perhaps link me a CWM package for ics to download?

No problem. I'll post a link in awhile.

Files
Ok, so here are your files.
Unzip the contents of the zip file to a folder on your PC
Boot your tab to the bootloader menu, select Fastboot.
Connect tab to PC, then wait 30 seconds or so (windows has to recognize it)
Then, go to that folder. Hold "Shift" + "Right Mouse Click".
Select "Open Command Window"
Type in the following;
fastboot flash recovery recovery_thor17_403.img
and hit enter. Should transfer good.
When finished, boot tablet to recovery like I mentioned earlier. DO NOT boot to the system. Or you'll be doing this all over again.
Install ICS or CM10 rom following the instructions on the ROM post. I suggest starting out with Civato's ICS Flex****** rom first, or one of the stock rooted ones.
Should be good...... I hope.
MD
Thanks again.
I did the fastboot recovery thing. But when I go to reboot, I have to turn it on and select "Boot Recovery", when I do its stuck on the screen "Skrilax_CZ's bootloader v8: Booting recovery kernel image"
Is this whats supposed to happen or am I supposed to see a different screen?

Shut down the tab. Reboot holding V- and PWR release when you see the text. Should reboot to recovery.
If not, your partitions are probably hosed.
Then it's Timmy Deans Rollback tool time. Will have to turn you over to dibs_nz for that one.

That brings me to the screen "Skrilax_Cz's bootloader V8: Booting recovery kernel image." But it doesn't go any further?
Well crap.
Sounds like some partitions are messed.
Try this NVFlash package;
http://d-h.st/32X
It's a version 3 bootloader using NVFlash. Might work.
Put your tab in APX mode (I believe you press and hold the pinhole reset, then PWR. After 3 seconds, release PWR, 2 seconds later release pinhole. Might have to reverse it, don't remember)
Plug tab in. PC should recognize.
Unzip to a folder, open a command window, and run the batch file (type it into the command window, xxxxxxxx.bat then hit enter)
If there's an error, it should show in the command window.
Here is a link to Timmy Deans roll back package;
http://d-h.st/0x7
The issue here, is you need a UID number, which I HOPE you wrote down when you did the V8 bootloader!
MD
Well I cant manually put it into APX mode, tried a few times. Also there is no bat file in that download... as for Timmy Deans roll back package, is it a simple method taht should work? At this point I just want to get my tab working again . And yes I do have my UID number.
Ok,ok.
So this morning I tried to fix it again. And I think i managed to put it in APX mode. Also, I started up APX flash tool and all, did that. Suddenly a cmd window opened and started doing stuff. And now the tablet says in the top right corner "Acer Iconia APX mode", and a yellow glowing 'acer' title in the middle (which is different from what I've been seeing). Another cmd window opened by itself saying "Nvflash started [resume mode]. Where do i go from here??
Thanks!
So I think I've gotten a better understanding of how this all works today. I've tried multiple ways of flashing recovery imgs ect, flashing the bootloader and all that stuff. And all the times I've done this, it always stops at "Nvflash started [resume mode]" and doesn't go any further.
So I'm not really sure what else there is to do.
Please, I need guidance. (below is my last attempt, and what It said in the cmd window).
Flashing bootloader: bootloader_v8.bin ...
Nvflash started
[resume mode]
Formatting partition 4 please wait.. Command Execution failed cmd 13, error 0x12

command failure: format partition failed (bad command)

U guys need to run the babsector.rar file to reset yr tabs partitions and you must have yr cpuid/sbk.
The file and instructions to use it are in post 2 of the root guide in my sig.
If u get any errors you must post the output. You may have a faulty memory chip. If that's the case, a new motherboard is the only fix.

Thank you so much for the reply. I gave up this afternoon and just flashed the ota 4.0.3 version from Acer and it seems to be running really good. The only reason I was looking to flash something new is because the update from honeycomb to ics didn't take very well and I've always been dealing with problems from it. If the flashed version is still running well I might not try a different Rom again. I'll be putting your tip in my notes in case I do. Thanks again.

So I rooted and then flashed a Custom Recovery Image. Then I followed the instructions under the babsector portion of your post. I got to this part: Go back into apx mode and run 501 B.bat, Reboot into recovery and do the wipes, Reboot!!!
I wasn't sure what "do the wipes" referred to so I did ALL the wipes. Cache/Dalvik/Battery/ and Data(?) When I rebooted it went back to the green screen and says in yellow: "Invalid primary (LNX) image." and has the same menu as when I rebooted after 501 A.bat
Now what?
EDIT:
So I was sitting there with the green screen/yellow error and decided to boot into recovery again. I then reflashed my custom rom, and did a normal reboot. Everything is working now! My FIRST custom rom after owning android devices since the ancient Motorola i1 way back in the day. I'd still like to know if what I did was right or what happened, so I can detail it in my instructions for my next custom rom project.

Dude I know it's been 4 years since you wrote that but I just wanted to say you really saved my life, THANK YOU!!!
About 2 months ago I tried to unlock my tablet's bootloader but I gave up after reading different articles and obviously ended up with a really bad headache. Last night I realized Android 3 is really old and I almost can't install anything on it. So basically I gave it another shot and been reading and downloading different files for almost 3 hours. Today I managed to unlock bootloader and use your short instruction (more likely a walk-thru that how you fixed your problem) and it worked!!! I owe you man... I owe you
I even took it to so many different mobile centers about 3 weeks ago but they said its files are not anywhere/we can't do it/it's too risky/it's not possible deal with it
Happy to help!
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.

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.

and now my tablet says, "entering acer download mode"
and "PASS" in big letters.
-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
and then for each mount option I have a format (format /system, format /data, etc...)
If I do have to delete the boot.p file, how is that done?
-edit-
This post was made 30 mintues ago and the cyanogenmod logo is still on the screen swirling after the new flash and reboot.
-edit 2-
45 +/- minutes now. I'm shutting it off again.
-third notoriously annoying edit-
I repeated the steps and tried a different ROM, CM 10 flex again. Still no joy. Been sitting at the animated boot screen for a few minutes now...and coffee is already made since the last ROM reboot.

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

EDIT: did u run the 2nd bat file from babsector??
Hi Everyone
A while back I was having all sorts of problems trying to flash a patched bootloader to my Acer A500 So that I could install a custom recovery, Custom ROMS , etc...
Well thanks to some help from this awesome site, and a member here that pointed me to an NVFlash archive (Bab-Sector) with a script in it and it worked perfect. The Script however was using the V8 bootloader instead of V9, and I wanted to go with the V9 Bootloader 03.14-EXT So I updated the scripts to install the bootloader to SkrilaxCZ v9 Patched for Acer A500, and I also added Thor2002ro CWM 1.7.3 touch, instead of 1.7. 1.7.3 works a whole lot better
*****************************IMPORTANT**************************
Before using these tools make sure to back up your tablet first, and have a good ROM ready to install once you have your patched bootloader installed. Using this tool to Install the patched bootloader will render your current ROM unusable. You will have to install a new ROM as soon as your finished. This will also fix all the partitions on your tablet, so that they are all correct, but in doing it destroys your current install.
So any way here is a quick guide to flash the patched V9 bootloader file on your Acer A500:
Before you Continue:
You will need to know your SBK
And you need to have all the proper Acer USB drivers installed.
Plus you will need this file: A500-Bootloader-V9_Babsector
Extract the contents to some folder, and open the folder.
Now power off the tablet, and while it is connected to your PC via USB take a paperclip and press the reset button (located on the side next to the full size USB port, a small hole) and the power button, slowly count to 3 then release the power button, count one more to 4 and then release the reset button. Now your tablet is in APX download mode.
Open the folder where you extracted the bootloader and tools. Double click the file a501 A.bat. Enter your SBK.
The bootloader will be flashed, and Thor2002ro CWM 1.7.3 Custom Recovery will be installed, upon completion the screen will say PASS.
Now hold down the power button until the tab turns off, then hold the vol down button along with the power button to boot into CWM. Once in CWM navigate to the mounts and storage menu, then format system partition twice. Now go back to the power menu, and power off the tablet.
Now you need to boot APX download mode again, take a paperclip and press the reset button and the power button, slowly count to 3 then release the power button, count one more to 4 and release the reset button. Now your tablet is in APX download mode again.
Back to the folder where you extracted the bootloader and tools again. Now double click the file a501 B.bat.
The bootloader will be flashed again, and Thor2002ro CWM 1.7.3 Custom Recovery will be reinstalled, upon completion the screen will once again display PASS. You are finished, and you have a good custom recovery, along with the best patched bootloader for the A500.
Now you are ready to install custom ROMS from Thor2002ro CWM Touch.
If you decide that you no longer want to have the patched bootloader you can restore your A500 to complete stock ICS4.0.3 with this ROM: Stock ROM Acer_AV041_A500_1.033.00_PA_CUS1
You can flash this ROM with CWM or rename it to update.zip and place on root of external SD and the stock recovery will install it also. after the ROM has installed the tablet needs to reboot and the bootloader will be installed, then the tab will reboot, and you are back to 100% stock Acer_AV041_A500_1.033.00_PA_CUS1. You will not have root, and the bootloader will also be stock. This is the file you need if for some reason you should ever need to have your tablet sent to Acer, to be worked on. under warranty for example, or if you just want to have the tablet returned to stock.
I really hope this little guide helps someone, I know that a few months ago this would have helped me out when I could not flash my bootloader from windows with either the Black Thund3rAPX tool or AfterOTA, both of which are excellent tools, but for some reason they just would not work with my tab until after I had flashed my bootloader with NVFlash the way I explain here.
Also I need to point out that the scripts and tools included in the bootloader archive are originally the Bab-Sector tools. I just updated the bootloader files to SkrilaxCZ V9 Bootloader, with the green Acer logo, and the Custom Recovery to Thor2002ro CWM Touch 1.7.3
Thanks
- Kaiji
Omg! Thank you!
Thank you, thank you, thank you. I've been trying for two days to get a custom recovery to install. I too used Blackthund3r's tools, but nothing was working. I think my partition table was screwed. It took me forever just to get the drivers to recognize APX mode. Google's generic driver's > Acers! Again thank you so much.

Nice guide Kaiji...a quick question. Do u know why babsector requires u to run both bat files. A few folks have just run the first one, done the formats then flashed their rom. Seems no one had any problems. Could u explain ( to a noob like me how babsector actually works? ??

Actually both of those batch files are identical, I believe that the original writer wanted to be sure that any corrupted data, and or partitions were repaired. And that is exactly what they do.What happens is after the tab is in apx mode a temporary rw bootloader image is uploaded, and then the file correctly maps out and create the partitions needed for you tablet, then it uploads the bootloader, and recovery images. now with your new patched bootloader you can boot to custom recovery, install custom ROM's, and you could even install a second OS and set up a dual boot scenario, Skrilax_CZ has some really great tutorials on this here. You will also find that Blackthund3r's tools will also work now too.

I am very happy that you, a senior member, actually thinks the guide is good. It really does mean a lot ( to a noob like me
I have actually just been poking around, and learning alI I can. I have always been a big fan of the Linux system, and the fact that it is now, in its Android form so huge world wide, on smartphones, and tablets everywhere is awesome!!
Any way I do really love that Android is based on the open source Linux code, and since it is, it's 100% customizable, hackable, & rewritable, sweet!!.
Oh yeah, To continue on a bit more about babsector, from my last post. The way that babsector actually works is this, while the tablet is is the NVidia APX download mode, the program NVFlash can then upload the special temporary APX mode bootloader image with rw abilities so that NVFlash can then set the partitions, and upload you patched bootloader. At least I believe that is how it all works. As I said I am just poking around, hehehe, an old linux user trying to learn all I can and then pass it on so everyone can enjoy the full potential of their devices.

Hmm, I wonder what the problem could be.... I would say for starters, try reinstalling the drivers, reboot, and try the script again. making sure to runit as Administrator. Also do you have AfterOTA? send me a PM after you try reinstalling your drivers, and if you are still having trouble tomorow, I will PM you my phone # and I will do my best to help you solve this over the phone.
I will be online tomorow around 12:00 noon EDT and will look for your PM and/or a reply

No problem , I am very glad your problems were resolved. And, if you don't mind, I have a few questions for you.
1. What exactly went wrong in your situation?
2. Which tablet are you using?
3. And, how did you solve your problems exactly?
The reason I ask is that each tablet/software combination may each be a little unique, and the details of your experience can be very helpful to others as they encounter their own situation, and most of all we can always learn more from everyones different case, and apply that knowledge to improving the ability to help in the next case. Also, please try to be as detailed as possible, if you decide to answer the questionsI asked.
Thank you very much for your input

Well it got me from only booting to APX mode to having a bootloader, but I'm still having problems. I ran the script and got the PASS screen. Now it boots to the bootloader but I'm no longer able to use the reset button to get to the APX mode. Even when I hold the reset button while powering on, it just goes to the bootloader. It also does this just powering on without press the -vol button. I'm assuming this was because I was also getting an error message say the Lnx kernel was invalid.
So I went ahead and flashed the A500-stock.zip and no longer get the invalid kernel message but it still boots to the loader menu with the options Primary (LNX), Recovery and Fastboot. But when I choose the first option it hangs on the first screen saying "Booting Android Image from LNX partition..." Revovery takes me to the recovery menu and Fastboot connect me to my PC in ADB mode.
Any suggestion about where I go from here?

I got APX mode working again. I had to fall back to Win 7. In Win 8 it couldn't find tthe APX driver.
So, I started from scratch and ran the A501.A bat, then formatted the /system twice. Then rebooted into APX and ran the a501.B script and got this error. "Formatting partition 2 BCT please wait... FAILED!" What now????? PLEASE HELP!!!!!

im having the same problem as u were having with the attachments on the error codes u got can u share some light to me on the solution u was told to use
Im about at my wits end and gonna make a paper weight out of this thing I guess. I had recovered it with the Timmy Dean tool once already, and was on HC for about a week. I wanted to upgrade to ICS. So I tried to flash to bootloader but somehow got to where I can only boot into APX mode. I keep hanging on every tool I use. Here is a screen shot of the error when using the babsector in this thread. As far as I know I have the correct drivers from Acers site, but not sure about the adb drivers. I have them, but they don't "install" like the acer drivers did. How do I know they are correct? See my error attached photo. Is it possible to have something so messed up that even though apx mode works, it still wont flash itself out of the problem?
Need help with running A501 A.bat
Hi there. I put my tablet into APX mode by following the instructions above. However, when I run the A501 A.bat script, it reports that "USB device not found"
I have my tablet connected to my desktop via a USB-miniUSB cable. The connection works fine when the tablet is on, but it doesn't register it when the tablet is in APX mode
Any suggestions? Thanks!

Just a couple suggestions, I would start by making sure you have a known good micro USB cable, make sure it's plugged into a USB 2.0 port directly connected to you motherboard and not a USB hub or a USB 3.0 port as those can cause problems. The last thing I would recommend is to use Windows 7. Windows 10 may or may not work with this method as this tablet is pretty old. You can use a virtual machine to run Windows 7 and it should work fine. Hopefully this helps a bit.

I am unable to connect directly to the motherboard, as my PC is actually a laptop, and I don't really want to try and open it up. I did manage to use a vm and try this on Windows 7 with no luck . If anyone has any other suggestions I'm all ears. The only thing that I think might be causing these issues is that I'm using a USB 3.0 port (My laptop doesn't have 2.0 ports), so I'll update this reply once I find a computer that has usb 2.0 ports.
Also, do I need to install a custom recovery before running the A500 A and A500 B scripts? Are there tutorials on how to do that? I think I ran into issues last time I tried because I hadn't unlocked my bootloader (tablet wouldn't enter recovery mode). But, if I understand it correctly, the instructions for this thread tell you how to unlock the bootloader, but it also requires the custom recovery or else you lose your stock rom. It's quite a catch 22

Yes you need to unlock your bootloader before you can get a custom rom or a custom recovery. But to do that you need root first. Also when I said connect your USB cable directly to your mother board I meant just any USB port on your motherboard.

That would still involve opening up my laptop, no? Also, I don't think that the USB cable is the issue, as I am able to connect just fine when the tablet is powered on, but not in APX mode. Also, I have tried rooting it before with a couple methods, both of which failed in one way or another. I'm open to trying out some other method(s) if you have a suggestion
