Iconia Common Questions & Answers - Acer Iconia A500

I've seen the following things asked again and again and again, and yet there seems to have been no attempt to make a Q&A for our tablet, so I figured I might as well take a shot, especially now that the mods have given us a proper Q&A section. I don't expect this to be fully comprehensive, but I'll try to cover the important stuff at least!
1. Q: I have an A501, can I use one of the A500 roms, either stock or custom?
A: No, absolutely NO! Well, actually, you CAN, but if you do you WILL lose 3G capability, so don't. There are currently no custom ROMs available for your tablet, sorry. Hopefully that will change soon.
2. Q: Can I root my A500?
A: Yes. There was originally a modded Gingerbreak root for the Iconia, but it only worked on 3.0.1 and has now been superseded by an updated root method. See the following thread for more information:
http://forum.xda-developers.com/showthread.php?t=1138228
3. Q: Is the bootloader really locked?
A: Yes and no. The bootloader itself isn't actually locked as such, but the ROM *is* protected by a hash key. This has been bypassed thanks to sc2k with a great utility called "itsmagic".
4. Q: So how do I use "itsmagic"?
A: The easiest way is to install the custom version of Clockwork Mod, by thor2002ro. See the following thread for more information.
http://forum.xda-developers.com/showthread.php?t=1126364
5. Q: Wow, I'm a newbie and installing that looks complicated. Is there an easier way?
A: Absolutely! Install the Acer Recovery app and it will take care of installing Clockwork Mod AND itsmagic for you, as well as backup your stock recovery!
https://market.android.com/details?id=com.interphaze.AcerRecoveryInstaller
6. Q: I'm scared of Clockwork Mod, is there an easier way to install a custom ROM?
A: Absolutely! From the makers of Acer Recovery, there's the Acer ROM Flasher app!
https://market.android.com/details?id=com.interphaze.Acer_ROM_Flasher
HOWEVER This app does NOT run the "itsmagic" utility (yet), so it's probably better for you to flash from CWM for now (Thank's Euclid's Brother for pointing this out!)
7. Q: Hang on a minute, can't I use the Clockwork Mod that's on the market? How about ROM manager too?
A: Simple answer? No. Our Clockwork Mod is a custom built that runs the "itsmagic" utility at the right time, preventing people from accidentally bricking their tablets. Do NOT use the one on the market or you will brick. As for ROM manager, it's not compatible, sorry. Use the Acer ROM Flasher application instead
8. Q: OK, so I'm rooted and I've got Clockwork Mod installed, now what?
A: The absolute first thing you should do, EVER, before installing a new ROM, is to make a backup of your current on. This feature is built into Clockwork Mod and is really easy to use. Do it.
9. Q: OK, I made a backup, now what?
A: Visit the Developer section of the A500 forums here on XDA-Developers, and you'll find several excellent custom ROMS, as well as links to stock ROMs, for your ROM flashing pleasure.
10. Q: I don't want to install CWM, I just want to flash a new stock ROM, how do I do that?
A: There are several threads detailing this, but to summarise, there are several things you'll need to do.
1. Locate and download the stock ROM you want.
2. Unzip this ROM to your PC. If you get a message about an invalid ZIP file, then you'll almost certainly need to run it through the Acer Update Decrypter first. See below:
http://forum.xda-developers.com/showthread.php?t=1099673&highlight=acer+recovery
3. Once opened, extract the update.zip file found inside this zip.
4. Copy update.zip to the root of your external SD card. NOT the devices internal storage. It won't work from there.
5. Make sure you have more than 60% battery, or plug in to the AC adapter, and turn your device off.
6. Hold down the Volume Down key (the left side of the rocker when device is in landscape orientation), and hold down the power key. Keep both held down until you see 3 rows of white text in the top left corner of the screen. Your device will now flash the update.zip on your SD card.
NOTE: There are several types of update you can flash.. Many are incremental updates and will be smallish (40mb or so). This can NOT be flashed on a device that has had ANY changes at all made to any preinstalled files, as this is an incremental update. However, if the update is 300+mb in size, it's almost certainly a full ROM and should flash fine. If it doesn't though, try a factory reset first.
11. Q: I cannot connect to my WIFI hotspot, why?
A: There are 2 possible reasons, so it depends on exactly what problem you're having.
1. The Iconia does not seem to support wifi ad-hoc (or peer-to-peer) mode. To connect to this kind of hotspot, you will need to modify a file called "wpa_supplicant" and you must be rooted to do this. See below for instructions.
http://forum.xda-developers.com/showthread.php?t=1060909&highlight=ad+hoc
2. Alternatively, if you're just getting a constant loop of "Connecting...", and never get an IP address, Acer have issued a patch for this, but it's for specific ROM's only. You can find this on the Acer update site, or can download directly below. Full instructions are included inside the ZIP file.
http://global-download.acer.com/GDF...AB&Step3=A500&OS=a07&LC=en&BC=Acer&SC=EMEA_27
12. Q: Help! I have a checksum error!
A: You probably flashed something and didn't run itsmagic... This is potentially very serious, but all is not lost. sc2k has been kind enough to provide instructions on how to fix it.
http://forum.xda-developers.com/showthread.php?t=1129873

<Reserved>

Well done. Quite comprehensive.

Just want to point out.. the Acer ROM Flasher (not to be confused with Acer Recovery Installer) does not run itmagic.... (yet..) It was made for a very specific purpose and has not been updated since itsmagic came out.
So, If you use Acer ROM Flasher, which will flash boot.img and system.img, make sure you run itsmagic yourself BEFORE flashing the images. I'll update it to include itsmagic when I have time.
Acer Recovery Installer is really the best way to go. Then use Clockworkmod for your backup/restore and custom rom installation.

Noobie Question about ICS

I can't post in the development forums so I figured I would ask here:
I understand how to use adb and fastboot, etc.. What I am missing is with the new ICS ROM it states that I must "fastboot flash system system.img"; however none of the ICS zip file I have seen come with a system.img file (just the boot.img).
Am I missing something? Any help would be greatly appreciated..
I used the version available on Rootzwiki... not sure if thats the answer you wanted. I'm running 4.0.3 ICS on my wifi XOOM OC to 1.54. No FC's, reboots or anything of the sort. You'll need to be sure that you have su-install.zip, and other img files needed. As I said, you'll find them all on the rootzwiki website under xoom hope this helps, if not good luck.
You are talking about two different things here. I don't know where to start here you're all mixed up. There are several ways to flash a ROM, you can fastboot flash the .img files such as what you are referencing to. Or you can flash an update .zip file from recovery. The way you flash the ROM depends on the source, if its a bunch of *.img files you use fastboot, if it's a *.zip file you use recovery. Just follow the directions given for installation that are provided with the ROM you are downloading.

Hello, and welcome to XDA! =] Anyways on with your question. There are two ways to flash a ROM to your xoom. One being fastboot/adb, where you use the command line on your computer to send commands to your device and make it do stuff. This is where you use system.img, boot.img, recovery.img.
The second, is CWM (ClockWorkMod recovery) This, as far as im aware, is the most common way. This is where the .zip's come in. Because you take the .zip you put it on your external SD card. boot into recovery (after flashing CWM of course) and flash the rom. CWM is nice because you can also make a 100% snapshot of your internal memory state via making a nanodroid back up. That way if anything messes up you have a 100% backup you can restore at anytime if you need it.
In a nutshell, You use *.img files with fastboot and .zip files with CWM.
Anyways. If you're new to rooting. Please check out these two threads, They'll help you get started. =]

The second guide I did use to flash my own zoom so I can assure you it does work.

[Q] Go to stock to get OTA ICS

I was just wondering if someone could point me to what I need to go back to stock and get OTA updates, I live in the US and would like to know which file to download, or does it matter? Do I need the full package? and which honeycomb version should I do? and which file under the version of Honeycomb should I get? or does it matter? Sorry about being n00bish I just would like to get back to stock so I can start over with this thing and get the info down about it.
Hi,
I've been using AfterOTA to go back to stock. It's very easy. I used version 1.01 which isn't available now but 1.07 should still be able to do the same thing.
Which file you use is important as they are geared for different regions of the world. A lot of the files from the Full Package thread aren't there anymore so your choices are limited. It needs to be a full package though, it should be over 300MB. An update won't work.
Basically, you use AfterOTA to install the bootloader and recovery from it's stock tab. Have the update.zip file on the root of your SD card (some of them need to be decrypted). After the tool installs the stock recovery boot by holding down the left or top volume key. That will automatically install whatever update is on the card. Version 1.01 had separate ICS and HC bootloaders I'm not sure how 1.07 is set up. Then just let the update process happen.
I doubt that you'll find anything earlier than HC 3.2 for your (our) region. If you just want a stock ICS tab you could just use that update.zip and skip HC entirely.
Good Luck
Can you point me to the stock ICS zip we would use for our US tabets? I found a page on here http://forum.xda-developers.com/showthread.php?t=1113878 but they dont have an ICS Full Package and I don't know which HC 3.2 one to use. it says to look at my current version but I am on a flexreaper ROM. I want to remove the recovery and bootloader and go completely stock and upgrade to OTA ICS so I can then run After OTA to get a fresh new recovery and ICS bootloader. thanks for your help.
My stock 1.104.02_COM_GEN1 OTA'd to 1.033.00_PA_CUS1.
From Vache's thread the Acer_A500_7.006.01_COM_GEN2 file will update to 1.033.00_PA_CUS1. I don't think this file needs to be decrypted.
1. Download that file. Put the update.zip file on the root of your SD card.
2. In AfterOTA on the stock tab choose A50x. This should install the HC bootloader and standard recovery.
3. Disconnect the tablet. Power down the tablet. Reboot by holding the left or top volume key while pushing the power button. This should start installing the update.zip on the card. If you wind up in CWM then AfterOTA didn't work and you'll need to downgrade.
4. Try to boot after the update. It will probably get stuck at the logo. If it does you'll need to hard reset (bottom volume key + power + slide rotation locker). It takes a while for the first boot and it might crash once while setting everything up.
5. You should be in HC 3.2 from here you can OTA all the way to ICS. You'll need to install the ACER update enhancer from the market b4 it will see the ICS update.
I hope this works for you.
CWM Recovery booted, instead of flashing the update.zip, How do I do it now?
I don't know why AfterOTA isn't working for you. I really thought it would. Oh well, Gersma says it's only for OTA. There are other people who probably know better, but I think you're going to have to get a stock bootloader on there before you can use any of those files. My guess its that you'll need to follow the downgrade guide. Search on "rollback".
I hope you find a better solution, but the rollback isn't that hard.
Good luck.
what if I apply the update.zip from CWM using the "apply update from sd card"? would that just force the up date and wipe everything with the stock bootloader and ROM that is in the update.zip?
I don't think that file will work from CWM. Maybe one of the stock ICS leaks would work. If you can load one from CWM it can load the BL and it will replace the recovery when it reboots. Then you should be able to use AfterOTA to return to stock and upgrade through the OTA's.

JB on A500/A501 [Working][New Links][No ICS Bootloader]

I had trouble finding a guide on how to get JB working on my a501 so I'm xposting this to xda. The link to the superuserfix was dead, but my install worked without it. I take no credit for this. Written by "dime" over at Tegra Owners.
I wanted to write a consolidated tutorial for people on the latest/unrooted 3.2.1 OTA and how to flash it to rooted Jelly Bean ROM. If you follow step 1, it actually installs an old version of Touch Recovery for you, so you do not need to bother with Acer Recovery Installer. All links are derived from the FAQ stickied thread.
1. First you need to obtain root. Follow this guide to install a rooted 3.2.1 image.
All data will be lost. The 10 step guide is included as a PDF in the download:
http://forum.xda-developers.com/showthread.php?t=1307539
Confirm you have the Superuser app installed once completed.
2. Download the following 4 zip archives, put them on your A500 external SD card, and do not extract them.
Touch Recovery: MOD EDIT: LINK REMOVED
Both latest JB ROM and GApps: MOD EDIT: LINK REMOVED.
Superuser Fix: http://www.mediafire.com/?xyznxalycnw9znw
3. Reboot your A500, and hold VOL- button until you boot into recovery.
VOL- is closest to the power button, what some would consider to be VOL+ on a phone.
Once in recovery, use VOL+/- to navigate the menu and power button to select.
4. Now that you are in recovery:
Go into the Wipe menu, and do a Data Wipe.
Go into the Install Zip from SD Card menu, and install/upgrade to the latest version of Touch Recovery.
Reboot the A500, and once again go into Recovery (hold VOL-).
Go into the Install Zip from SD Card menu, and install the JB ROM.
Go into the Wipe menu, and do a Data Wipe. (yes a 2nd data wipe)
Go into the Install Zip from SD Card menu, and install GApps.
Go into the Install Zip from SD Card menu, and install Superuser Fix.
(skip Superuser Fix if there comes a time when superuser is working by default)
Reboot the device (Don't hold VOL- this time).
5. You should now be in rooted JB.
Backup your apps with Titanium Backup or MyBackup Root.
Hope this helps.
Hi and thank you for this tutorial.

Hi there....I'm just wondering how this works!!!!!
If I understand your guide correctly then,
U run timmydeans v4 rooted HC bootloader
check s/user
Flash 1.7.3 ics recovery, the ROM, gapps and s/user fix
Then enter recovery wipe/flash etc....
So, not only did u manage to flash a recovery, u r also running JB - all without the unlocked boot loader?????
I have to give this a go....if this really does work you have made my day, lol
Sent from my A500 using Tapatalk 2
EDIT: k I've just read 60 odd pages from the JB ROM thread - and answered my own question...seems this tegra-owners ROM runs with or without the patched boot loader....interesting!
EDIT: ok i tried this anyway even tho i was running the patched bootloader....may explain my issues!!
had troubles right from the get go - The tdv4 EUU wouldnt recognise my tab in apx mode, after mucking about I got the "Pass"
rebooted into cwm - nup - stock recovery??? weird....
found a boot.p file so renamed that and installed acer recover installer to flash cwm 1.7
from there flashed cwm 1.7.3 and the rest of the guide!!!!
could not install super user fix zip kept telling me there was an error and had aborted installation...s/user seems to be working ok
so after 7 hours I have thors JB with the 3,01 BL
perhaps it could be made clearer that this guide is for tabs runnin gingerbread or HC, altho it will work on the v8 BL the question would be why you would want to....however for those who havent updated its not as complicated as trying to get ones head around patched bootloaders, nvFlashing etc.
JUST A WARNING not all ICS/JB roms can be flashed like this MOST WILL REQUIRE the patched bootloader....
ALWAYS BACKUP and ALWAYS CHECK THE DEV's OP for whatever rom u intend to fllash, and if u dont understand something
please ask stating what rom/BL config you're on and what you're trying to flash to!!! Its alot easier than trying to talk/msg your way out of a brick

I dont use a sim card. but on my a501 it asked me to please insert sim during first boot and always has a signal bar in the bottom right the indicates no reception. So most likely yes. Hope that helps.

Thread Closed
Thread is currently closed and links removed for the following reason;
Thor202ro rom kernel violates GPL. Otherwise know as not releasing kernel source. Most people here in the forums are well aware of the fact that non-GPL compliant kernels are not allowed to have links directly posted to them. This in the XDA rules.
The reason GPL is in place, is so that things like "carrier IQ' don't happen again. This is why kernel source should be open-source. Without it, the kernel could be transmitting personal data, and nobody would know it.
Additionally, the website in question, is a revenue generating website, and thus this also violates XDA rules by having links posted to revenue generating websites (ad-fly) to download Thors software. So this is a touchy spot.
Most people know where the site is anyhow.
And no, I am not going to re-hash the history.
Any issues regarding this, then please contact XDA Senior Moderators.

Going to stock without CWM

Hey guys. This is my first post. Okay so I have a Iconia A500, running Lightspeed_4.5. I flashed this a while ago, I don't even remember how I rooted it. Here's one of the problems, I don't have any type of Recovery. I tried using the Acer Recovery app to put a recovery but that will not work. I just want to go back to STOCK with NO ROOT. Also i'm a noob at all of the stuff, so please make it simple.

Head to this thread and download one of the FULL packages HC or ICS take your pick...
Unzip it and extract the "update.zip" -
Copy to your external sdcard - it must be named update.zip not update.zip.zip!!
Power Off your tab
Hold volume down button and power on again
Tab should display "erasing data, erasing cache" and then begin the update process
If you have trouble unzipping, the file will need "decrypting" see that attachment for the decrypt tool...Your antivirus will see this tool as a trojan but don't worry its fine....run the tool and add your zip as input...in a minute or two in the output box - you'll see a "......decrypted.zip" . then you're good to extract the update.
Also make sure you use a FULL package not an Update package - i know the terminology is confusing - you want an update.zip from the FULL package, not an update from the update package

Update fails - want to flash custom rom - need some advice

Now here's the situation:
I'm still on an older ROM version (4.2.1 - see attachment)
A while ago my tablet told me there was an update. I wanted to get it, it downloads but it always fail to apply the update.
What I've done to the device so far is that I've used motochopper to root the device and got rid of some ASUS apps.
So since it refuses to update, I've decided to unlock it, flash a custom recovery and get myself a custom rom.
But I've read a lot about people bricking their devices and I doubt it'll be as easy as it was on Nexus 4 and Nexus 7 - so I need some advice on how exactly to do it.
Recently I found the thread that enables us some sort of nvflash although being on JellyBean. They were talking about a specific version of bootloader and I'm not certain if I have this bootloader since I'm on an older JellyBean version. Of course I would like to use this bricksafe as well - just in case
Can someone lead me to a guide or instruct me how to do it? I don't want to brick this device
Thx in advance

This THREAD has all the info you need to do NVFlash. It's based on 10.6.1.15 something bootloader which I believe is the same as the latest Asus official. If you're on 4.2 rom, you can flash the flatline img. and generate the necessary files from there. Once that done, you can use either the provided CWM or the latest 4.2 TWRP to flash any compatible custom rom (4.3). Have fun.

First of: thanks for your reply
Guide says something about bootloader 10.6.1.15.3 - I still have an even older one (10.6.1.8...) - will it still work?

Yes, that version will work because it is on the 4.2 bootloader.
Sent from my TF300T using xda app-developers app
Only works on unlocked device?
Ok I'll try like this
These are the steps I would do: (I pray someone to look over these steps and correct me if I'm wrong )
1.) Go to asus site and download unlock_v8 and run it so to unlock my tablet.
2.) I go to androidroot.mobi and download flatline_tf300.img and nvflash-tools-win32.zip (win32? Hope that does not stand for 32-bit and hope it will work on 64-bit)
3.) I reboot my device into Fastboot (don't know exactly what that means "Please note that for transformer tablets the fastboot command might require the option "-i 0x0b05"" - at this stage the device is already connected to the pc and just in case it's not in fastboot I should run this command?)
4.) I use cmd.exe to type in these commands. In which directory? In the directory where I unzip the files from nvflash-tools-win32.zip? The guide is not too specific on that.
5.) I type in "$ fastboot flash recovery flatline_device.img" (I know for device I use tf300) which will flash the recovery.
6.) I reboot my device (let android boot?) and reboot again into recovery. (power + vol down?)
7.) I select "Advanced - Wheelie" and Step 1: Flash AndroidRoot BL and find myself with a custom bootloader.
8.) It says the device will power off. Automatically? However, I boot into android and after that reboot again into recovery mode.
9.) I choose Step 2 which will generate wheelie blobs
10.) I follow the on screen prompt to retrieve my blobs (anyone has a screenshot of that? Or is it self-expalantory?)
All this time the device is connected to pc via usb?
11.) Now I reboot my tablet into APX mode - after Step 10: am I still in recovery or booted to Android?
12.) If my tablet is recognized I type "$ wheelie --blob blob.bin" into cmd
13.) Then I will type in the commands to obtain the backups
Still got a few questions though. The device is connected to PC throughout this whole procedure, right? Where to start cmd (do I have to put the files from nvflash-tools into a specific folder from where I start cmd.exe?)
And after this procedure is done do I need to flash anything else? Or will I be then equipped with a working recovery that allows me to flash custom roms?
Thanks in advance for anyone who's taking time to answer my maybe uninformed questions but I'm kind of having troubles following the guide
