Can someone pl help me? I will describe my situation first.

I bought iconia and when i turned it on it updated itself (so i don't know the original stock rom version), i rooted it and removed doc to go trial version through root explorer. Later on i did a factory reset, its still on HC 3.0.1 with build 1.139.05_COM_GEN1. By the way i checked at the store the other iconias have 1.016.05_COM_GEN1.

Now its does not show any available update (3.1), either the update is not available in our region (middle east) or because docs to go is missing? By the way i couldn't find anyone having uploaded build 1.016.05_COM_GEN1.

Now i would like to try other roms but what should i do, just backup whatever stock rom is there in my iconia and where to start with itsmagic or CWM?

I hope someone would clear some of my confusion.

Can't wipe data....

Unfortunately, I can not get CWM to wipe my data. I get a line that says error erasing: data/data/andrybirdsrio (the path is not exact but you can get the point) Unfortunately i think this is leading to many FC's and i can't uninstall Angry birds rio to see if that has anything to do with it(market force closes when i click it).

I tried to put a "file" labeled erasedata in the CWM folder, but that seems to be doing nothing. Does anyone have any suggestions as to how i should proceed from here? I don't know what the file type should be so that could have a lot to do with it...

Any help is greatly appreciated!

This is my first posting, but i have been working with custom roms on my Samsung Captivate since i bought it as well as my Iconia since i bought it so i have experience with CWM and what not.
[Acer Iconia A500] Euclid's Brother:
Removing the Doc to Go app will not affect the notification of the new version, but it will affect the installation of an update.
[Acer Iconia A500] Euclid's Brother:
This is sc2k's trick to wiping data.

Hold the volume up key (yes, volume up) while you power on, keep holding volume up. The Acer logo will display, then dissappear. While STILL holding volume up, switch the rotation lock on then off a couple of times. You should see some white text at the top about data being wiped.
[Acer Iconia A500] Caraddicted1989:
And it is working again! Thanks so much! I really appreciate it! I will have to write this down on my desk for future use..

Just wondering... Do you know what might have caused the problem? I have been using CWM to backup and restore my settings when i flash roms and i think that's the cause of my problem, but i'm not sure. I used to use titanium backup on my captivate, but it always backed up system settings and that seemed to lead to problems here and there as well...

Thanks again!
[Acer Iconia A500] usman3206:
Thanks a lot for u r kind answer, that means the newer HC 3.1 update is not yet available in our region, i hope to find original stock rom for our region on this forum some day and restore 'docs to go'.

Can u kindly advise me as to whether i should backup this updated stock that i have at the moment (of course without doc to go) before trying other roms or something else?
[Acer Iconia A500] FloatingFatMan:
2 minutes of using the search in this section, or just scrolling down, will find you multiple full stock ROMs you can use to reflash to your tab. Just find a version that matches your current one, and follow the instructions.

Simples.

Hi,

I have a question, after rampant flashing many roms, I am starting to get the random reboot associated with the HTC Diamond/HD2 etc that is fixed by running a task 29... (Links to the TASK29 guides are in my sig..)

is there any way to perform this on the a500.

I know that task 29 is a task specific to the HTC bootloader but there has to be a way to do something similar here!

[Acer Iconia A500] The Real Guchi:
this is working great
[Acer Iconia A500] usman3206:
Thanks for your answer, though everyone calls u rude but your answers are crisp. I did read acer iconia forum in full and i know there are lots of roms available.

What i am worried about is what to save for recovery as my stock rom was updated when i first turned it on and i deleted 'docs to go' trial version and that i haven't seen my regions' stock rom version available anywhere.

Secondly, i had some confusion regarding using CWM or itsmagic, there are just so many things about recovery etc; that i am reading and things are clearing now.
[Acer Iconia A500] FloatingFatMan:
If you're going to restore one of the full stock ROMs, you can do it with the stock recovery, no CWM needed.

You WILL, however, need to run the downloaded ZIP through the Acer Decryptor (it's in the dev section), as the ZIP needs to be decrypted. Once done, extract the update.zip from it, drop it onto your external SD card and reboot to recovery (Power & Vol down).

As for what to save... Apps can be reinstalled, app data, on the other hand, is slightly different. If you're willing to root your tablet, you can install Titanium Backup and backup the apps & data you want to keep, then restore them after reflashing.

As for which ROM to use, I really would recommend you grab one of the 3.1 stock ROMs that have been posted. Looking at the ROM versions you were on, the UK ROM will work fine for you, so you'll want the following thread.

http://xdaforums.com/showthread.php?t=1159443

That's the same region as me, UK and most of Europe. .38 is the latest ROM version for our region.

Unable to boot into recovery

OK...flashed virtuous picasso last evening and everything seemed to be fine...until the system started to randomly reboot itself. Now I'm trying to flash another rom through the acer recovery app and it simply won't work. It gives me the option to reboot through recovery and when I click yes, nothing happens. I've even tried to hold the power button and the -volume key down upon boot up and that won't work either, even though I know the rom is on my SD card.

Any suggestions would be appreciated...I'm about at my wits end after spending multiple hours trying to fix the problem!
[Acer Iconia A500] Euclid's Brother:
The Virtuous ROMs to do not have the "reboot" command, so the "Reboot Recovery" button doesn't work on those ROMs. At least.. the Thrive and Galaxy ROMs don't have the reboot command.. I haven't tested the others.

You can still boot recovery with the vol-down + power method. Or open terminal emulator or adb and type "toolbox reboot recovery".

When I get a chance, I'll update the app to work with these ROMs.

EDIT: When you are using the vol-down + power button, make sure you continue holding the buttons after the vibration. Keep holding them until you see white text in the upper left corner of the screen.

More testing on the RESTORE bug..

If I remove .android_secure.img from my backup set, then this is the output I see after a full restore has completed:

(Note: This is a "Full Restore" from a previous "Full Backup". Of Stock 1.141.07 to be exact, but that's irrelevent)

ClockworkMod Recovery v5.0.0.0(thor2002ro rev1.3.4)

Fixing A500 Boot/Recovery Checksums...
Running itsmagic
Done!
Checking MD5 sums...
Erasing boot before restore...
Restoring boot image...
Restoring system...
Restoring data...
.android_secure.img not found. Skipping restore of /sdcard/.android_secure.
Restoring cache...
Restoring flextrom...

Restore complete!

That's great...

BUT..

If I do a full restore but leave the .android_secure.img in the backup set, I see the progress down to "restoring data..." with the filenames flickering below. When the data.img restore is complete, it appears that clockworkmod immediately restarts at the beginning.. it clears the output from the restore. It does not ever show the lines about .android_secure, cache or flexrom, nor the Restore Complete message and those partitions DO NOT get restored. The only output seen after this point is this, as if you just booted cwm:

ClockworkMod Recovery v5.0.0.0(thor2002ro rev1.3.4)

Fixing A500 Boot/Recovery Checksums...
Running itsmagic
Done!

Can anyone else reproduce this?

It's simple to test.. Just do a FULL BACKUP with an micro sdcard installed, then a FULL RESTORE and see if you ever see the cache, flexrom and "Restore complete!" messages. Or, after the data restore, does it reset and wipe the output from the screen.

The issue does not occur if the FULL BACKUP was done with no valid micro sdcard installed. The .secure_android.img is generated from the .secure_android folder of the micro sdcard.

Thanks..

PS: Attached is the recovery.log from the above two FULL_RESTORE's.

The first full restore begins at line 106 and ends at line 159

The second full restore (the one that fails after data) starts at line 164 and fails at line 190. There's no error msg about the failure, it just restarts clockworkmod w/o completing the restore.
[Acer Iconia A500] whiskeyriver:
Thanks for the reply...

I guess what I'm trying to do is flash another rom instead of the one I currently have, and clockworkmod doesn't seem to be working. I've followed the tutorials on this website and everything worked great the first time...just cant get to the recovery screen where I can wipe the device, restore, or flash a new rom. I've been doing the volume and power button method correctly as well...just gives me an android with an exclamation mark by it. It's driving me nuts...I thought you could flash and reflash different roms numerous times...or am I wrong?
[Acer Iconia A500] thefightback:
Same problem here too. I have flashed many of the roms before going back to stock and now on OTA 4.010.38 and CWM will not work at all.
[Acer Iconia A500] Euclid's Brother:
Sounds like you have a stock Tom installed. Reflash cwm then try it again.
[Acer Iconia A500] Euclid's Brother:
When you flash a stock rom, cement is overwritten. Reflash cwm.
[Acer Iconia A500] thefightback:
Thanks' works again now.
[Acer Iconia A500] agentfazexx:
Is there any benefit of this over the Acer Recovery thing off the Market?
[Acer Iconia A500] whiskeyriver:
I'm assuming you are talking about something other that simply deleting the acer recovery manager and reinstalling it?

Perhaps you could point me in the right direction as to how I might go about reflashing cwm (a link would be great)!

Thanks for all your help!
[Acer Iconia A500] Euclid's Brother:
Not sure what you mean.. CWM is the recovery used to install custom ROMs. Acer Recovery Installer, simply makes it easier to install CWM.
[Acer Iconia A500] Euclid's Brother:
(Just noticed the auto-correct changed cwm to cement in my prev post)

As my post, just prior to this states. CWM and Acer Recovery Installer are 2 different things. Acer Recovery Installer will install CWM for you. CWM is what is needed to install custom ROMs.

When I said "reflash CWM", I mean, run Acer Recovery Installer, select Clockworkmod from the list and click "Install Recovery Image". That re-installs CWM.

In the case which I was refering to, the user (was it you? not sure..) had flashed a stock ROM which overwrote CWM with the Stock Recovery image. So, to get back to CWM, you have to install it with Acer Recovery Installer.
[Acer Iconia A500] agentfazexx:
I know what CWM is, obviously.

Well I don't know how to use adb push. So how do I install CWM via the Acer Recovery Installer?
[Acer Iconia A500] whiskeyriver:
Thanks for all your help...got it working again! Love the forums here...lot's of helpful people for noobs like myself just getting into the Android scene!

Take care my friend!
[Acer Iconia A500] FloatingFatMan:
Run it and all will become obvious.
[Acer Iconia A500] agentfazexx:
That's all I wanted to know. I already installed it. Much easier using Acer Recovery Installer than doing what the OP said.
[Acer Iconia A500] claytonmedic:
I just installed CWM and did a backup after using the Acer Recovery app. Very simple.

It's a little bit of a pain to use CWM because there's only a volume up or down button (up or down select) and the power button (enter) but there's not another button to go back if you need to. For example, I was looking in the "advanced backup" options, and there wasn't any way to back out (couldn't even turn off the power because that's used as the "enter" button) and just had to perform the only option I had, which was the advanced back up.
[Acer Iconia A500] Euclid's Brother:
Yeah, the back option should be the last menu option of any sub-menu, but sometimes it disappears and there's no way out. You just have to hold the power button in until it shuts off.
[Acer Iconia A500] claytonmedic:
Yeah, it must have disappeared then, but it's good to know I can just hold down the power button to get out.
[Acer Iconia A500] tpaulideu:
Same Problem - md5 check at restore failed

md5sum: not found

What can I do?

Thanks

Thomas

Edit:

is this way possible:

Restoring to factory defaults via Terminal #2

1. Root

2. Install Terminal Emulator, Busybox installer and Acer Recovery Installer

3. Copy system.img, flexrom.img, boot.img, recovery.img in /mnt/sdcard

4. Run (flash system.img last, it will lock down your tablet and you won't be able to flash the other .img files): /data/data/com.interphaze.AcerRecoveryInstaller/files/itsmagic

dd if=/mnt/sdcard/flexrom.img of=/dev/block/mmcblk0p6

dd if=/mnt/sdcard/boot.img of=/dev/block/mmcblk0p2

dd if=/mnt/sdcard/recovery.img of=/dev/block/mmcblk0p1

dd if=/mnt/sdcard/system.img of=/dev/block/mmcblk0p3
[Acer Iconia A500] Euclid's Brother:
Can't use the dd command for system and data images that were backed up via CWM. They are not the right kind of image file.

The need to do the md5sum as I described is to see which file(s) mismatch to determine if the backup is OK to use.

Install busybox, then you should have access to md5sum command. If you have busybox but the symlinks are created, try:

# busybox md5sum *.img > md5.txt

Once the md5.txt file is created, compare with nandroid.md5 to see what's not matching. You can fix the nandroid.md5 file by using what is reported in the md5.txt file that you generate. But understand, if you restore a corrupted image, things might not work well.
[Acer Iconia A500] officetally:
Wait.. so if we're using a terminal on the tablet to do this, which files do I need to download, where do I put them on the sdcard, etc.. I don't want to mess this up haha

[Acer Iconia A500] tu3218:
I installed CWM using the acer recovery app. Now I went into rom manager to make a backup and its saying I don't have CWM installed and that I need to install it. And when I went to install it, the acer iconia tab didn't show up in the list of devices. Any suggestions?
[Acer Iconia A500] Euclid's Brother:
ROM Manager is not compatible with the Acer A500.
[Acer Iconia A500] daveid:
If Thor would make the code available, or if someone else does it all over again, it could be integrated with Rom Manager properly. Maybe you could make Rom Manager work by opening the menu and selecting Manual Flash Override, this may be bad, as some functions could brick your device (I am only guessing, but stuff might not work right on our devices, so I would stick to making backups and booting to recovery).
[Acer Iconia A500] tu3218:
Okay, that's what I figured. So to make backups, just boot into recovery manually and do it that way? I'm so use to making backups straight through RM on my thunderbolt. I just want to make sure thats the way to go.

same problem...somebody pls. help.
[Acer Iconia A500] FloatingFatMan:
The "Unable to mount SD" is a well known problem, a little searching would have found you the solution in a few seconds.

CWM has an issue with the way some cards are formatted. Either you need to reformat your card in an android phone, or try another card.
[Acer Iconia A500] nexgenasian:
Hi, I'm a little lost.

The first step, when you are saying you run ITSMAGIC. Are you in clockworkmod for iconia? The screen has orange text and background image of a circuit board.

During this you're able to connect the a500 to a pc and have it respond to ADB commands? Do have to press home on an attached keyboard first to get to console of clockworkmod? or are you in any screen of clockwork mod? HELP! Thanks.
[Acer Iconia A500] Euclid's Brother:
It's best to be in clockwork mod (orange text with black background and circuit board) and run those commands from an adb shell (from a pc). You can't run the dd commands from CWM interface unless you write a script to do it. So has to be from adb connection. Don't worry about the itsmagic step, because CWM runs it everytime it boots.

However, you CAN run the commands from a normally booted iconia, using adb or a terminal emulator. Again, it's best to use adb, because the tab will lock up while flashing system. Using adb, you'll be able to tell when it's done. MAKE SURE TO RUN ITSMAGIC FIRST.

Either way, you'll almost certainly need to do a data wipe.
[Acer Iconia A500] jm77:
It would be awesome if it was, but I don't foresee this happening.

Why is another question.. :/
[Acer Iconia A500] shin lucifer:
thor2002ro just updated recovery to 1.4. If you Google tegraowners. You can find it.

EDIT

Thanks i didnt know that.

NVM then... lol
[Acer Iconia A500] thor2002ro:
you can update via old CWM 1.3+... just flash the zip

and since it has my kernel you cant add it to market or xda...
[Acer Iconia A500] Euclid's Brother:
Thanks for the update thor, it looks great. I LOVE the blue, instead of the orange :)

To All:

As thor pointed out, I cannot inlclude this version of clockwork mod in Acer Recovery Installer, without violating the GPL (General Public License).

HOWEVER, Acer Recovery Installer can install ANY custom recovery image (including this one), by choosing "Custom or Stock recovery.img from micro sdcard" from the list. Just make sure you have the appropriate "recovery.img" file in the root of your micro sdcard.

Question:I have all of my roms backed up,when i go to restore one/any of them,my root permissions denies everything that needs permission,i tried a reboot,didnt work,so i end up having to install the rom on top of the restore to get superuser to accept access.What do i do to clear this up,or is it a bug?Thanks for your help.
[Acer Iconia A500] josinpaul:
New version 1.4.1 is out
[Acer Iconia A500] O.a.T.:
I too am seeing this. Like you, I used to dirty flash the rom, but lately I've just been using iconiaroot to reroot. That seems to be working fine and it is faster/easier.
[Acer Iconia A500] mevensen:
When you do a wipe in this fashion, what is wiped?

After such a wipe, what do I have to do to get back to my prior functioning setup (hopefully without the corrupted data folder).

I have a CWM full backup of my current setup. I also have a full Titanium backup.

Do I have backup my data off the internal SD memory?
[Acer Iconia A500] mevensen:
Does this "problem" actually need to be "fixed"? The reason why I ask is that I get this error, but everthing *seems* to be working fine -- and by everthing, I mean that I can still do the following successfully through CWM, despite the error:

- backup and restore (although I run into the /data formatting issue, still have yet to try to address that)

- flash recovery and ROMs from external SD

Since this is an external, removable SD card, I use a card reader to transfer data (which is faster and easier than going through the tablet). I can also manipulate all of the files on the external SD with Root Explorer on the tablet.

So, is there something that I am missing that requires "fixing"?

I ask this because I don't want to copy the 16GB of data on and off of the card for a re-format. I'm also not sure what I would use the reformat, since most of the advice is to reformat using another Android device (i.e. phone). My phone is the Nexus S 4G, which does not use external SD cards.
[Acer Iconia A500] mevensen:
Just a thought. If I do a full backup without an external SD card, it will save to the internal card. Can I then move it to the external card for storage, and restore it from the external card with everything intact?

It seems like you're saying the the problem occurs in the creation of the full backup to an external card, if I understand correctly.
[Acer Iconia A500] Euclid's Brother:
This method wipes EVERYTHING from /data, including /data/media (internal sdcard) which is not backuped by CWM. Only use this method as a last ditch effort to get your tablet to boot, or if you realy do want to completely wipe the tablet.

Otherwise, use the factory reset withing CWM. It does not wipe /data/media.
[Acer Iconia A500] Euclid's Brother:
No one else has confirmed this issue, though it happens to me EVERY TIME.

When you do a backup, the .android_secure folder form the external sd is backed up as .android_secure.img (It's hidden in the backup set and not included in the md5 checksum). This always gets backed up, even in an advanced backup where data is excluded.

Then when you try to do a full_restore from this backup, after it restores /data it attemps to restore .android_secure.img and fails formatting the device, which kicks CWM out of the restore function and back to the main menu.

I've not tried it with the sdcard removed. I didn't know it would fall back to the internal sdcard. Easiest way around the issue (for now) is to erase .android_secure.img from your backup folders.

Stay tuned to an updated version of Acer Recovery Installer this week... ;)
[Acer Iconia A500] mevensen:
But, if I understand correctly, the factory reset within CWM does not help with the /data corruption that thor states can be the cause of failing to format /data during a wipe or new ROM/restore flash.

I have not tried the "erasedata" file fix yet, but I'm curious which will be the best course of action to correct the failure to format /data during a flash.
[Acer Iconia A500] Euclid's Brother:
I'm not sure of the differences either. You'll probably just have to try one and see, then try the other if that doesn't work. Just be sure to backup your /data/media files first, if that matters. That's all the files that show up in Device Storage when you connect the tablet to a PC.
