Hey guys
I'm a happy owner of a new Iconia A500 bought from Amazon . It isn't brand-new but new-enough-for-me lol. It seems it was updated by OTA or something because it has Android ICS 4.0.3 on it.
Tech info:
Model: A500
Android version: 4.0.3
Kernel version: 2.6.39.4+
Image version: Acer_AV041_A500_RV05RC01_PA_CUS1
Compilation version: Acer_AV041_A500_1.033.00_PA_CUS1
Image part number: FM.S14A0.00Y
I read a lot and noticed there's a lot of info but it isn't very organized. I see there is CWM and TWRP, there are stock ROMs, ICS and JB and maybe a linux or two out there, but the instructions on using them aren't very clear.
I know I have to back up my SBK because it's something important. Thing is, how to?
Actually, in the case of a brand new Iconia which I want to get JB/any-other-custom-rom on it and have the possibility to go back to stock in case I screw up (or in other words, how to avoid a brick or how to recover from one if possible), what would I have to do?
In other words, what would be the steps I'll have to follow in order to play safe and backup my current state so I can start flashing custom ROMs like custom JB/ICS and kernels? what do I have to read and in what order? I already have experience in flashing & cooking ROMs, recoveries & bootloaders for HTC Magic, Motorola Defy and MT6577 devices, but this whole nvidia environment is new to me.
Thanks in advance!

DARKGuy,
I just recently took the plunge and experimented with various ROMs. The link below pretty much details all the required steps and links to files:
http://forum.xda-developers.com/showthread.php?t=1622425
Remember proceed at your own risk !!. Before doing anything, backup any items (docs, mp3, books, pics, etc) you want saved.
DOWNLOAD ALL FILES BEFORE STARTING !
Practice placing the A500 into Recovery Mode ( PWR + (-) Vol key) and APX Mode (PWR + Reset button (paper clip needed)). You need a micro SD card installed to perform the upgrade.
Download the latest USB drivers from ACER (1.00.0524) and install into PC. Verify they work in both USB drive mode and APX mode. Make sure tablet has USB Debugging enabled (Settings). Verify the drivers work. Boot tablet normal and connect to PC, you should see Acer Tablet with SD drive and External SD drive (if micro SD installed). Files\folders should be viewable. Turn table off, then restart into APX mode. You should see new hardware found, ADB driver. You shouldn't see any errors in device manager. If everything is working fine, you're ready to proceed.
Basic Steps:
1) Get CPU ID. I used File Explores ES app. Folder Local\Sys\Firmware\Fuse and the file is acer_cpu_id. Text file. Remember to add a zero in the beggining. ie mine started 33c20c.... My CPU ID is 033c20c....etc, Write it down.
2) Download the tool and generate your SBK with the CPU ID. Write it down. It's 4 sets of numbers, ie 0x520A1300 0x78498901 etc.
3) Root device. Here' the link: http://forum.xda-developers.com/showthread.php?t=1546593.
4) Install bootloader and recovery rom. I used Blackthund3r APX tool. Option 17, ShirlaxCZ V8 Bootloader and Thors 1.7.3 recovery tool.
Once this have been completed, successfully. You can download any JB\ICS you'd like to load. Just boot into recovery and load from SD card.
I would also download a stock image in case you want to go back.

Hey sorry for the late reply, I must say that was a very elaborate yet useful answer and I was able to backup my important data aswell as installing ROMs like crazy. You rock man! big thanks for the help and guidance!
root
get bootloader + thors recovery 1.7.3 cwm base(only cwm i found to work with aroma installer. which some of the newer roms is a must)
backup your files before u wipe.
flash away.
trying to find a rom that will let us a500 users use multiwindow manager, this would be superb!
will post back i find that golden ticket.

Before you Begin:
This guide is a basic how-to for installing a custom ROM & its update for the Galaxy Tab 10.1v… For all those who struggled (like me)
Also, this is for Windows… If requested, I’ll dig up the Linux method.
REMEMBER: This is all done at your own risk.None of the people mentioned, or myself, can be held responsible for any damages caused! Following these steps will void your warranty.
If you are not comfortable, don’t do it!
Always keep a backup of your data; it will get lost at some point during this!
(Titanium Backup, Rom Manager etc can create backups… use ‘em!)
This guide assumes you’ve already unlocked & rooted your Tab. If you haven’t, check these threads:
(Much thanks to these gents!)
Bcmobile’s unlock thread
Chainfire’s unlock thread
Bcmobile’s rooting thread
I recommend Chainfire’s method to unlock – you get a stock ROM (unlocked) + ODIN3 in case something goes pear-shaped…
PM me if there is something I’ve missed, need to take down or redo.
I do not provide support for the ROM(s)/ programs mentioned; go to the appropriate thread (list at the end).
Above all: have fun and thank the devs who put in so much time!
Required Packages:
Java SDK – found here:
http://www.oracle.com/technetwork/java/javase/downloads/index.html
Android SDK – Found here:
http://developer.android.com/sdk/index.html
USB Drivers – install via Android SDK Manager. See here:
http://developer.android.com/sdk/installing.html
(USB Package r4)
USB Note:
After installing the drivers via the Android SDK Manager, navigate the folder where you installed the Android SDK, and look for a folder called ‘extras’. Open that, then open the folder ‘google’, then ‘usb_driver’. Edit the android_winusb.inf file and insert the following text under the section [Google.NTx86] (32bit Windows) or [Google.NTamd64] (64bit Windows):
========
;
;Galaxy Tab 10.1v
%SingleAdbInterface% = USB_Install, USB\VID_04E8&PID_6860&REV_9999&MI_01
%CompositeAdbInterface% = USB_Install, USB\VID_04E8&PID_6860&MI_01
%SingleAdbInterface% = USB_Install, USB\VID_04E8&PID_6601
%SingleAdbInterface% = USB_Install, USB\VID_0955&PID_7000
========
All other files needed are mentioned under their specific section.
Ok, now onto the good stuff…
===============================================================================
Installing a custom ROM:
(I’m using Seo’s ROM purely as an example, as it includes a wipe file and updates. You can use whichever rom you like/ want/ need. Just check the rom’s thread/ site for any special instructions)
This example uses the TB Galaxy ROM, it can be found here - http://forum.xda-developers.com/showthread.php?t=1155023
You’ll need to download V1.0 FULL ROM, whichever update you need/ want (this guide uses 1.0.9), and wipe.zip.
Place the downloaded .zip files in your Android SDK \tools or \platform-tools directory (whichever one has adb.exe in it)
[FONT="]1) [/FONT]Download and install Rom Manager from the Android Market (The free one is fine).
[FONT="]2) [/FONT]Open Rom Manager, and select ‘Flash Clockwork Mod Recovery’ (CWM). If you used bcmobile’s unlock method, you can use Rom Manager to back up your stuff, just remember to copy it off the Tab before moving on!
[FONT="]3) [/FONT]Once it has completed, connect the Tab (powered on) via USB (debugging enabled) and open a command prompt. Navigate to your Android SDK’s \tools folder and type:
adb devices
[FONT="]4) [/FONT]Now, push TB-Galaxy-1.0.zip to /sdcard/:
adb push tb-galaxy-1.0.zip /sdcard/
Copy the 1.0.9 OTA update zip as well as the wipe.zip using push.
Check the attached file for the pic...
(Mine has nothing listed after devices, as I didn't connect my Tab...)
NOTE: Seo’s instructions call for copying the file(s) to /sdcard/media/, but for some reason CWM does not let myself see that folder…
[FONT="]5) [/FONT]After it has copied, type:
adb reboot recovery
[FONT="]6) [/FONT]Once in Recovery, navigate with the volume keys, and select ‘Install Zip from sdcard’ with power button (TAP to select). Browse for the wipe.zip and select it. Select ‘Yes’.
[FONT="]7) [/FONT]After the has been completed, install TB-Galaxy-1.0.zip.
[FONT="]8) [/FONT]After it completes, navigate back to the first CWM menu and restart/reboot the tab. Be aware that the first boot may take a while.
[FONT="]9) [/FONT]If all is well, you should be seeing your new home screen… Check it out!
========
If you’re stuck in an endless bootloop or it gets stuck at the Samsung logo screen, go to chainfire’s unlock thread (link at top of page) and follow the steps there. You’ll have the stock ROM loaded back on, with the bonus of the bootloader being unlocked.
========
[FONT="]10) [/FONT]Update time… Connect the Tab via USB, enable debugging, open a command prompt and navigate to the Android SDK tools folder and reboot into recovery: adb boot recovery. Follow step 6, but select the OTA zip instead of wipe.zip.
[FONT="]11) [/FONT]Once that completes, reboot & enjoy. Done!

However to Windows users who just can't get the proper drivers to work (like my case, I tried every method for a week), just install Ubuntu. Way easier...

You're welcome.
The fix by modifying the android_winusb.inf and pointing Windows to it cleared the problem for me, as did installing Samsung Kies and letting it auto-install the driver.
Otherwise, Ubuntu could work...
Yeah I know it works for most of people but check the latest posts in all the guids topics, I tried almost everything, doing things right but Xp or 7 could never connect to the tab.
I'm just saying, as an info, that if someone encounters the same issue, Ubuntu (or Linux) is the answer...
Works like a charm. Can I remove the .zip files afterwards?

Hi guys, time to cry for a little help here...
today I've managed to get 3.2 loaded on my p7100. everything went well and I was really enjoying it, until I got a crappy app that started to freeze the tab before I could remove it (AVG 2.9). I tried everything I could and after a "fastboot -w" the tablet entered in an endless loop mode, restarting all the time. I've fixed that flashing the stock rom using ODIN, but now I cannot get into clockworkmode to reload the 3.2 rom. every time I enter "fastboot boot recovery.img" (clockworkmode recovery image), it displays on the tab "Booting downloaded image" but doesnt go any further... dont know what to do now... it is working fine with 3.0.1, but I cant get 3.2 back.
thanks a lot for your help, it is much appreciated !!!!
Cheers

Forgot to mention: trying to boot into recovery mode leads to a screen with the android dude and a big yellow exclamation mark (adb reboot recovery) and nothing else happens.

Is your bootloader unlocked?

yep, I think so
Hi Isimobile, thanks for your help.
I believe it is unlocked (can see the open padlock when I turn it on, fastboot mode says unlocked and I even tried "fastboot oem unlock" once again to make sure). dont know what else to do. It seems there's something wrong with the restore partition (hope Im not saying anything nonsense here).
Cheers

Downloading Afterota at moment. I did find out the cpuid another way.and a side coverts it to SBK. so have both now.
This is how i found out cpuid
[HOWTO] Installing the unlocked bootloader and fixing broken recovery in leaked ICS - xda-developers
will get afterota and make sure is right and get the sbk to.
edit: ok downloaded and unziped Afterota and double clicked Afterota.exe and get error Uac must be disabled before using Afterota. Disable it manually and reboot your pc. program will exit.
???? any ideas?
Ok found out how to disable Uac and got Afterota to run and had to install the driver. and got the Afterota file saved to desktop with all the details of the tablet in it cpuid and SBK.
Whats the next step to do?
Sorry im a noob at this.

Hello,
I am another unfortunate user who has bricked his tablet. I installed Jue11 Ram Manager Plus and it asked to reboot my tab. On reboot it was bricked, flashing the android logo and not going any further. I have tried everything listed on the site to get my CPUID to no avail. have followed all instructions including trying to retrive using Ubuntu Linux, A500 Flash Tool, (which tells me it is in APX mode but returns a blank serial), NVflash gives a device not found. Any help? I am technically saavey on PC, Windows and the like, but fairly new to tablets.
A little more info, using A500 Manager it reports a500 in APX mode then acts like it is retrieving the serial but comes back blank. Nvflash reports device not found. Using Ubuntu gives errors but reports all needed packages are installed, (not a Linux Power User so could be an ID10T Error on my part).
Please, I appreciate any and all help.

if u meant rom manager - our tab isnt supported, you'll need the patched BL before u can install a custom recovery
if nvflash is reporting device not found then check your data cable and/or that the acer usb boot recovery is installing from apx mode. You may need to manually install it by pointing it to the acer folder in program files/data depending which win OS u have...
try that and see how u get on...

So, i have been tasked with fixing an acer tablet. I have been searching these forums for a few days to try and figure out how to fix this tablet.
The issue is, it sits at the ACER logo screen (this would be an easy fix on my GNEX). Sifting through the threads i decided to post here to help me move this along faster.
I can get the device into the bootloader. I am presented with the following -- Bootloader v0.03.12-ICS: Starting Fastboot USB download protocol. I can not use fastboot as the bootloader is locked and i can not unlock it (from searching i found i need to installed a patched version, and that is where i am running into issues).
I can not figure out his CPUID. Since the system will not boot, i can not use a terminal to get it. this tablet was completely stock so no CWM on it. I thought i had it showing in ADB once, but i have never been able to get it back into that mode. (any tricks, i thought it should work if i am in the bootloader, i installed the driver from acer, but i does not list any devices, tried another usb port).
I have also tried putting an update.zip file on the sd card and booting into stock recovery, but that ends up with an android with the red ! mark above its belly.
so, i ask you guys for some help. Is there any way i can fix this tablet?
EDIT:
when i do a fastboot devices, i just get a ? fastboot. and nothing for ADB
The tablet also responds to fastboot commands, mainly reboot, anything major and it tells me denined (that it is locked)
EDIT2:
I have blackthund3r A500 manager running, i got the tablet into APX mode, at the bottom it says A500 detected in APX mode. When i click Dump dmesg to desktop, it created a file but nothing is filled in it. When i clicked view dmesg, it says - error: device not found.
Also, under device manager i am seeing a device called Acer USB boot-recovery driver. When i get it into bootloader it shows up as a ADB driver.
Thanks

I'm going to assume you have an A500 and NOT an A501.
It appears your stock recovery is probably also working, as if it weren't, you'd probably go to APX mode. As it is, you get the Acer screen.
Regardless, here's a list of A500 ICS full update files on my Dev Host server. I've already decrypted, and named each one a little different so you won't get confused. Put one of them (the zip file, DO NOT EXTRACT) on your external SD card. Then power on your tablet holding either PWR & Vol+ , or, PWR & Vol-. Can't remember which for stock recovery. See if the update will install. You'll see some text in the upper left corner, then you can release the buttons.
http://d-h.st/Zf8
http://d-h.st/2cm
http://d-h.st/gw8
http://d-h.st/KXl
Now, you may have to try more than one of these updates. Some work, some don't. But try each one and see if it completes install. This is about the easiest way to begin with.
If it don't work, then probably have to get a linux ubuntu install to get the UID number.

The updates did not work for me (was I not supposed to change the names of the archives to update.zip?), and I have the exact same issue as the author of this thread (minus the part where he's doing it for someone else, It's my tablet). Is there a way to get the CPU ID on XP? I do not have access to a Ubuntu installed computer, although I have Virtual Box installed on my XP and when I set up Ubuntu on it, it did not work.
thank you
thank you, it worked for me.
i formatted my SD card, and i renamed the file i downloaded with ------> update
i copied it to SD card.
i pressed Power button + Volume button (-)
it took me less than 2 minutes to update.

I found a partial solution to the problem. you need to download a file archive called babsector.rar. It has two batch files in it that will basically do the same thing as blackthunder's tool, the only problem being is that the tool won't work for me. The other part of the bad side is that now I need help to flash a kernel onto mine without the tool.

Put one of them (the zip file, do not extract) on your external sd card. Then power on your tablet holding either pwr & vol+ , or, pwr & vol-. Can't remember which for stock recovery. See if the update will install. You'll see some text in the upper left corner, then you can release the buttons.

now, you may have to try more than one of these updates. Some work, some don't. But try each one and see if it completes install. This is about the easiest way to begin with.
If it don't work, then probably have to get a linux ubuntu install to get the uid number.

I might have one or two of the files lying around on my computer let me see if I can find them and upload them.
Hello,
I have been asked to troubleshoot an ACER iconia stuck at boot logo. I am not sure if what I read here is applicable to the model I got. Here is what I can read on the label at the back of the tablet :
ACER iconia One 10 B3-A20 Model A5008
FCC ID:HLZA5008 IC: 1754F-A5008
So is "A500" topics relevant for that tablet ? I don't see any topic about "iconia one 10" or "A5008" ...
Thank you for your answers.
Stock firmware reinstalled
Replying to myself !
Found stock firmware from that Acer link, entering model etc.... (change language FR to what you need).
Then copy downloaded file to SD-CARD, and restore firmware from the recovey menu (pressing "Vol Down + Power" to enter.
Then Restart ... Cool.

Hello, I believe my kid had rebooted my tablet during an OTA update. I've been diligently reading page after page of posts trying everything possible to reflash this.
What I know:
- a500 16GB / win8 server / debian VBox
- a500 was rooted prior to OTA update
- can enter apx ( blk screen, wht power) and recovery mode (loads update.zip)
- I can get most recovery update.zip's to start, but so far, all have failed.
- A500 manager detects a500 in APX mode but states i need to install drivers. (repeated this many times)
- nvflash does not communicate (i'm thinking due to the incompatible drivers)
- "fastboot.exe devices" returns nothing- SBK and CPUID
What I don't know:
- the last version of OS on the a500. Maybe HC?
- if the device retained USB debugging before it bricked
- whether or not I installed CWM or other needed programs (was almost 3 years with no issues)
I have tried any images i can locate; mostly in the forums here. I'm not positive if I can just load them from SD, in recovery boot ( if the files are correct format) or if I need prior steps. I have tried every zip making sure it's "update.zip" although the contents of each are not always the same.
Any ideas or perhaps "guide for idiots" would be greatly appreciated.
Thanks!
edit: so I have located the CPUID and managed to find a working SBK calculator. Now I'm having issues related to .NET 2.0 when running the nvflash utility? I'll attempt an XP vbox to see if it's now due to win8.
new edit: the drivers don't seem to work on Win 8 or 7. I tried installing an XP vbox but I am not able to activate, therefor install proper utilities for the nvflash program.
It seems I'm stuck, unable to work around the .NET 2.0 conflict and the driver installation.
Perhaps I'll start looking at linux alternatives and hope someone could provide some more of an updated approach.
