Well, flashing a custom ROM on our beloved Iconias became quite easy now thanks to developers on xda. Most of you are quite familiar with the procedure but there are still people that ask basic things all over the ROM developement threads. This is just a beginner's guide, an attempt to collect all the procedures and tools in one thread. Nothing of this is my work and I would like to say THANK YOU to sc2k, thor2002ro, Euclid's Brother, Chainfire, monki-magic, drellisdee, ezterry, Skrilax_CZ, gersma and all A500 developers for making this possible.
You will need the following: external SD card, root rights, unlocked bootloader (if you're on stock ICS), custom recovery and a custom ROM of your choice.
Well lets start by placing an SD card in the SD card expansion slot. Its file system should be FAT32!
*This is optional: To be sure it is recognized later in CWM, format it first with SD Formatter - a tool that can be downloaded from here. Use your home computer / notebook with a card reader for this procedure. Alternatively you can do this using an ANDROID phone.
1.ROOT
Root for Honeycomb 3.0.1 by monki-magic
original thread by Slowie911 here
1. Make sure usb debugging is turned on and unknown sources is selected in Applications settings.
2. Have a micro sd card inserted and turn the tablet on portrait mode and lock it with the switch to fix it in portrait.
3. Download and execute the attached apk. (i had to download from my comp and transfer to the tablet for it to work).
4. Once the apk is installed run the root procedure within the app which was installed
5. Wait and you will receive full root access.
Download Gingerbreak 1.20
Root for Honeycomb 3.1 by sc2k thread here
1. Goto Settings->Applications and enable "Unkown sources"
2. Download the attached APK file
3. Copy the file to your Iconia
4. Install the APK & start the tool
5. Click "root"
6. Enjoy

Download Iconiaroot 1.3
Root for Honeycomb 3.2.x OTA
Unfortunately there's no dedicated rooting app yet developed for HC3.2. It also comes with a new bootloader. In order to get root you need to revert to an older version of Honeycomb first where Iconiaroot works. How to do that is explained in details in this thread
UPDATE: if you're on OTA HC 3.2.x then you can just update to ICS and use the method for rooting ICS - links posted below
Root for ICS 4.x.x OTA

or
Full root for A500 ICS 4.0.3 - Simple method, posted by ZeroNull
2. Bootloader
Since there are many new ICS custom ROMs and custom recoveries, please read in their dedicated threads if they require ICS bootloader. Some of the ROMs can recognize the version of your bootloader and load the proper boot.img during boot. In general - if you're on Honeycomb - you have HC bootloader. If you've updated OTA to ICS, then you have stock ICS bootloader, that is unusable for flashing custom ROMs and therefore you need the unlocked bootloader. A guide on how to install it read here - thanks civato. This thread links to a nice little piece of software (option 1) by gersma that can automatically do all the job for you - install ICS unlocked bootloader and custom recovery. Read and download here - AfterOTA by gersma
3.Custom recovery
original thread with clockworkmod recovery by thor2002ro here
1. Open Market app with your tablet and search for Acer Recovery Installer.
Acer recovery installer
2. Install it and then open it. It has ClockworkMod Recovery by thor2002ro rev1.3.4 built-in.
3. Select "ClockworkMod Recovery rev.1.3.4 by thor2002ro". Tap on install Recovery Image. A popup offering to backup current recovery image will appear. Surely, buckup! Thus you can restore your original recovery image in case of need. Then CWM will be installed. Once it is installed you can remove Acer Recovery Installer tool from your system if you want.
thor2002ro updated CWM to 1.7.3. You can download the zip from tegraowners.com. Later versions of his recovery does not meet GPL because of the "mini" kernel of his - sources not being released. It supports flashing both from internal memory and the external SD card. In order to update your CWM to this latest version, place the downloaded ZIP on your external sd card and update from your CWM by choosing install zip from sd card. Alternatively you can extract the recovery.img from the zip, place it on your external sd card and install it through Acer Recovery Installer by choosing Custom or Stock recovery.img from micro sdcard.

RA Revamped for Iconia
TeamWin Recovery Project (twrp) - needs ICS bootloader
A500 Public Recovery
Since the creation of AfterOTA by gersma, you can use his software to install both the bootloader and CWM before flashing the ROM. Get it HERE
4. Flashing custom ROM
Download the ROM of your choice which should be a zip file. Place the zip on your EXTERNAL SD card. Power off your device. Now hold volume down and power buttons together until you see text appearing on the top left corner of the screen - you can release both buttons now. Wait until CWM loads. Volume keys (Up and Down) are used to navigate the CWM menu. Power button is uded as "Enter" i.e. to proceed with your selection. Before going on to install your ROM do a full backup of your system first. Navigate to "backup and restore" and then select Full Backup. Wait untill the operation completes.
Now do the following:
Wipe menu:
- wipe data/factory reset -> navigate to "Yes - delete all user data"
this should format you data partition and cache partition (dalvik cache is gone as well)
Mounts and storage menu
- Format System
this should format your system partition
The above commands are presented in thor's CWM. There are slightly different menus and sub-menus in the other custom recoveries but if you dig a little you'll find that they do the same things and you'll get the idea of what you're doing.
Now you're ready to install your ROM. Get back to the main CWM menu and select
- Install zip from sdcard -> choose zip from sdcard.
Navigate to your zip on the SD card and install it - choose "Yes" again to install. Wait untill installation is complete, return to the main CWM menu and choose "reboot system now".
You're done, enjoy your first custom ROM. Take time for its initial configuration.
5. Flashing custom KERNEL
Flashing custom kernel is as same as custom ROM. You place the zip (Kernels come in zip files as well) on your external SD card and:
- Install zip from sdcard -> choose zip from sdcard.
It is recommended before flashing a new kernel to wipe cache partition and dalvik cache. And of course first you flash the ROM and then the desired Kernel
6. UNBRICKING by flashing a stock ROM
thanks to vache we have full packages shared in his topic
vache said:
Once the desired file downloaded, you have to use Acer Update Decryter by thor2002ro to decrypt them.
After decrypting the file, you have to extract the update.zip from it, put it on an external SDCard (does not work on internal memory) and boot your tablet with Vol- & Power. The update will launch automatically.

This is fantastic. Thank you. I have had my iconia for a month now and been looking at flashing a custom rom but kept backing out. Just a couple of questions for clarification:
(1). Does wiping data erase the internal sd?
(2). If by some stroke of bad luck a flash is unsuccessful and a boot loop or similar occurs, am I right in my understanding that you can just go straight back into recovery and re-flash?
(3). What are the chances of bricking the tablet?
Sorry for noon questions, please just wanna certain because my gf bought me this tablet under the condition I don't do anything risky like on my x10 that I flash almost daily haha

1. No, it doesn't.
2. Yes. You can do that. There's another option in mounts and storage -> format system - that will format even your system partition and leave your device bare with no ROM files on it. That would be a really clean install I guess
EDIT: I just saw that system is formatted during ROM installation. So no need to do that
3. Always read first what option you've selected and be sure you understand what it does. If you have CWM successfully installed, you have a powerfull tool to restore reflash, wipe, format etc. I've flashed my HD2 hundreds of times and now my Iconia is on the run Never ever had a boot failiure.

VERY good information here. Thank you very much for taking the time.
I've flashed ROMS on my last two "chinatabs" but haven't gotten into it with my A500 yet. (To be frank, I'm still thrilled with the prospect of OTA updates from a manufacturer after my last experiences.)
It looks like the process is very similar to my Rena3 tablet.

Thank you, that lays it out all nice and precise for us all. Like strider_mt2k, I have been holdng off on the custom ROMs, because my first tablet was a Gtab, and while it became a pretty awesome tablet, it had to be flashed with a custom ROM to be really usable. The OTA thing was holding me back. But I think that I may try to flash the thing this weekend if I get the chance.
Thanks. Glad it could be of use.
nice tutorial dude! thanks!!
could you please make another tutorial to return back to stock?
specially to return back to stock te kernel.
thanks!!!
As mentioned, best case is if you've backed up your device before flashing any ROM or Kernel. Thus you can restore to your country specific version.
Otherwise its pretty simple - its just like flashing any other ROM following the steps described.

Unfortunately I can not tell you for sure. I haven't tried all of the custom ROMs but in most cases - no you won't be able. I've tried Tabooney, Honeyvillain, Virtuous Picasso, Virtuous Galaxy. ROM developers usually update their ROMs to the latest base available. I think it depends on many things - base, kernel, stock apps removed etc.
Maybe someone who have succeeded with custom ROM updating would share his experience.
Can anyone tell me if there is a version of ROM manager that supports the version of CWM that there is for the Iconia. I would love to be able to simplify my ability to backup my ROM's before flashing.

You can install a clockworkmod for Iconia no matter of the version of ROM manager. But it is much much easier to use Acer Recovery Installer. I recommend you using it instead of playing with recovery img files. It is a one time procedure after all
Anyway - here's what you need to do if you don't want to use Acer recovery installer, or you don't want to use ADB:
http://www.addictivetips.com/mobile/how-to-install-clockworkmod-recovery-3-using-rom-manager/
instead of CWM 3.x you will need to get CWM from thor2002ro In this guide you substitute the recovery that ROM Manager is about to flash with thor's CWM. I haven't tried this method myself but it should work.
With Acer Recovery Installer you can flash custom recovery as well. As long as you have it in IMG format you can be flashed from within the app - "install custom or stock recovery image from sd card".
great thread.
thanks!!!
Great Tutorial!!!
Just a couple of doubts:
First question: Backup files.
3. Flashing custom ROM
"...Before going on to install your ROM do a full backup of your system first. Navigate to "backup and restore" and then select Full Backup. Wait untill the operation completes. "
Where do the backup files go in the system? On internal or external SD card? Is it an *.img file extension?
Should i move it to my computer to keep it save, or just leave it where ever they are?
Second question: Kernel.
4. Flashing custom KERNEL
"Flashing custom kernel is as same as custom ROM. You place the zip (Kernels come in zip files as well) on your external SD card and:
- Install zip from sdcard -> choose zip from sdcard.
It is recommended before flashing a new kernel to wipe cache partition and dalvik cache. And of course first you flash the ROM and then the desired Kernel"
I am on Stock 3.1 ROM with original Kernel, if i want to try Virtuos Picasso, do i have to flash a new Kernel? And if yes, shouldn't i do it before flashing the ROM? Or just flash the ROM and then the Kernel? What happens if i just flash the Rom and use the stock kernel?
Thank you..
Your backup goes to your external SD card in a folder named clockworkmod\backup\2011-XX-XX.HH.MM.SS
As you can guess the name of the backup corresponds to the time it is created. This backup can be used to restore your system through CWM in case of need.
CWM does not backup /data/media folder. Additionally: you should also delete .android_secure.img from your backup set or a full restore will fail before it restores flexrom.
The last is an issue described by Euclid's brother:

No, of course! Your custom ROM (Virtuous Picasso in your example) and any ROM comes with its Kernel. Its up to you to decide wheather to change it or not after that by flashing another Kernel. Follow every Kernel developer's notes for ROM compatibility. So, that answers the last part of your question - you cannot flash Virtuous Picasso and still think you're on stock kernel

Oh, i see...i thought that the flashing ROM procedure of a custom ROM, would just flash the ROM and not the Kernel...so in this case i just have to choose the ROM that i want to flash and do not have to pay attention about the Kernel compatibility...unless i flash a Kernel only. Right?

Don't use ROM manager to install anything. It just boots you into recovery. When in ROM manager select the second line which says boot into clockwork recovery. Once in recovery, navigate to file and install.
Make sure you are NOT on the recovery that ROM manager suggests. You need 3.2RC4 by solarnz

Please help me to get further.
I got it back to work, but are there someone who can help me to get it like this

with the clock and the dock.
Welcome to XDA mate.
You have to know some basic stuff before flashing any ROM.
1. ClockworkMod recovery and how it works.
2. Find a ROM that you like and download it.
3. Follow the instructions written on that ROM for flashing via ClockworkMod recovery and you are done.
If you are looking for stock HTC look, you must download a Sense ROM (CyanogenMod is an AOSP ROM) and there are many of them. I would suggest reading from this post, it helped me a lot when I was new to the android scene.
If you have any questions please post here and I am sure people would be happy to help.
Remember... Search function is your friend here in XDA.
Cheers

Hmmm did you attempt to move or edit the nandroid backup? As far as I can tell, if you have nothing to boot too, then your best bet would be the same as instructions below, to boot recovery, mount sd, put new rom on there super wipe, and flash new rom

Md5 mismatch means that image is likely to be corrupt.
Google and download the md5 checker s/w. Check the md5 hash with the one posted on the forum/website where you are downloading the image.
If needed redownload the image and check the md5 hash again.
Once the md5 hashes match you may proceed flashing the image on to the phone.

Check "Root, Install ClockworkMod + Remove Bundled Apps from Official 2.3.5 by That-guy" link in my signature. It has guide to install clockworkmod, which you will use to install roms.
The only way (I think) is to backup those infos with titanium. I do not recommend it, because it might cause force closes in ICS if you restore them. After making backups and putting ICS zip to sdcard, reboot to recovery. You do this by booting phone while holding volume +.
Choose backup & restore and backup in there. Then do factory reset and then go advanced -> wipe dalvik
After it choose: install zip from sdcard and choose zip from sdcard from there.
Now navigate to ICS .zip file and choose it. Now choose reboot to system. It should start loading ICS now.

Hi guys,
I had a very strange problem, my Titanium Backup on android KitKat backed up all apps, but I could not restore them on Lollipop. When I verified the backups, TB said they were corrupted (using AOSP Lollipop). Switching back to KK and verifying the apps again confirmed my backups were okay. The only thing working on LP in TB was restoring app's data (only). So, how do you install apps from your backup created with KitKat on Lollipop?
Install android KitKat ROM
If you are already on KK, skip this step.
If you are on LP, take a nandroid backup, wipe your phone, and install any KK ROM. Install Titanium Backup on that ROM.
Make an "update.zip" package
Open TB, open batch menu and verify your backups (while the backups were "corrupted" on LP, they worked for me on KK).
Open batch menu, and find "Recovery mode" in the list. There's just one option (Create "update.zip" from app+data backups). Pick the backups you want to restore on LP and run it.
It will create a recovery script, with all the apps (including their data). You're done on KitKat, back to LP!
Install/restore Android Lollipop
Wipe your phone again, install or restore any LP ROM you want to use.
Boot your phone to LP, set your Google account and other things you want to.
Install Titanium Backup on your phone. Do NOT restore anything yet.
Reboot to recovery & install your apps from the file you created with Titanium Backup (usually "update.zip" in the sdcard folder)
Reboot (system), your phone will update android and setup all your application's. Do not open those apps yet.
Restoring application's data with TB
If the TB did not begin the data restoring process yet (you would see that as a notification), reboot your phone again (system).
Your phone should start restoring data to the application's you installed via recovery earlier. Let it finish.
That's it, you're done! Your backups from KitKat, that could not be installed on Lollipop via Titanium Backup are now installed and working!
WARNING: Even if you have to wait/reboot more times, do it! If you setup your apps manually, and TB won't restore any data, there's a huge chance it will start restoring them on the next reboot and it will replace the data you already setup!
Cool!
Just one point I confuse, step 4, "Reboot to recovery & install your apps"
What apps? and how do you install it/them from recovery?
Honestly, I've never done it that way b4. I install all .apk files when the system is up and running.

in the point 2. he said that you have to create an "update.zip" package that contains all of your apps & backup data...
then in step 4. you flash that update.zip through recovery

Exactly like he said, I'll edit it a bit to make things more clear.
4. Reboot to recovery & install your apps from the file you created with Titanium Backup
Get back to recovery and install the *.zip file you created earlier with TB in recovery.
Why do you need to say or add this step: "Reboot to recovery & install your apps from the file you created with Titanium Backup"
Why can't you just say
4. Reboot to recovery & install the *.zip file you created earlier with TB in recovery.
Why need to install apps in one step then get back to recovery and install the .zip file?
That's the confused part.

You have to restore them just one time, of course. I'm sorry i messed up with the description. Sorry to confuse you.
I fixed it now.
That's much better, my man.
G'day, m8
Thanks.
so i have to go back to KK and make an update.zip file thru TB, and then back to LP and install zip file via recovery...? do i understand this rite? is there no way stayin on LP and restore apps somehow? my verification says 0 errors, but still when i try to restore it gets stuck at 0% of restoring...
Yes, you do understand it right. There may be a way, but the only one working for me was this one.
Thank you
Big thanks for this!
You are welcome! Glad I helped!
How do you downgrade from Lollipop to KK?
Well that depends. If you are running LG's stock LP, then I am not sure. You better ask somewhere else. However, if you are running custom LP ROM, and you have custom recovery and rooted, then all you have to do is pick one custom KK ROM, flash it, and you are done. Use Pardus ROM, or CloudyG2, or CyanogenMod, whatever you like. It does not matter.

No. It works for stock LP as well. I was trying to say that I am not sure how to downgrade.

Okay. Now, i see. Thanks
Hi,
thanks for that great instruction. It worked very good on my Nexus 4 from Kitkat to Lollipop.
But one little failure.
Several app notifications (for example Quizduell, Tapatalk) don't come up after the update. Is there any chance to get them back, or do I have to reinstall that apps?
Try to open the apps. When you open the app, the notifications should start working properly. If they don't, just reinstall the app.
Will this work vice versa also?
Will this method work if you switch from lollipop to kitkat as well?
