My A500 is running Taboonay 2.2 with 2.6.36.3HoneyVillain-3.4+ kernel and Thors CWM. I need to return this to acer for repair. How do I go ahead making this thing stock as it came from the factory with no root and no CWM?
I have read all I can find on reverting this back to stock but I see many different ideas on doing it. Some are restoring to stock with root. Some don't have root but still have CWM installed. Can CWM be removed? I need this back to 3.1 stock and unrooted.
I have flashed many Android phones but while this is similar, I am just missing something.
What files would I need to do this?
What are the steps?
I hate feeling like a noob.
If I have been reading correctly, will downloading the CWM-ROM_A500_701414_GEN1.zip file from this thread. work to revert back to stock? Do I only use this file if I don't want root? Or do I need root since I would have to run Acer Recovery to replace CWM with the stock recovery?
Not real sure if that's all I'd need or not?
i would try a rooted stock rom. Download acer recovery from the market and iconiaroot from the dev forum (if youre rooted you know about these). Flash the rom, install stock acer recovery with acer recovery app, and unroot with iconiaroot. This should have you at 100% stock since you can find a stock rom only altered to have root quite easily in the dev forum.
If you have CWM loaded then just download the correct update.zip for your region and install it from your SD Card.

Thanks for the answers. How would I go about reformatting the internal sd as well? At which point can I do that without screwing anything up?
I'm assuming a hard reset after I get everything back to stock would suffice?

while you still have Root privilages with any ROM, use any file explorer app (example ES File Explorer) to view "\sdcard" or "\mnt\sdcard"
Option: Save data (if you wish off to pc)
Manually delete with explorer app.
after you've manually Deleted internal sdcard folder contents...
1. Option: Save all your apps or data (that you want) (cwm backup + save to pc or safe spot)
2. Do a full wipe and format of data (to get a clean fresh install of rom)
3. Flash Rom
4. Turn your tab in.
5. After you get it back, revert back to 3.01 or TimmyDeans way back to Root)
ROM : HC v3.2 (GEN2 = USA) (STOCK OTA non rooted, locked new bootloader kills CWM recovery) http://vache-android.com/files/Acer_A500_7.006.01_COM_GEN2.zip
Optional : there will be 2 small OTA updates (8 MB each) that will get you up to HC v3.2.1 (it will be 7.014.02_COM_GEN2).
What are you sending it in to repair for? In my experience, a broken power button, a revert back to stock was unnecessary. My tablet had cwm and Thor's rom loaded, they fixed it free of charge but had loaded stock 3.2.1 on it.

Hey, thanks all for the answers. I got it back to stock. I am sending it in because after two months a line of dead pixels appeared across the screen. I wanted it back to stock just because I didn't want to chance them calling me up and telling me that the warranty was void since I rooted the tablet. It is a possibility. I don't mind if they update it to 3.2.1 though as it can be downgraded. I jsut wanted no problems with the free fix.

Here's what happen when i send mine for repair.. My rear camera got broken because of the shor fall im running on a custom rom and im rooted.. i call them to send my tab for repair then i just revert/restore my stock rom backup but without unrooting it and returning the original acer bootloader.. to my knowledge that i just read somwhere in the forums that they will just update it to the latest version which is 3.2 and it will remove the root and revert to acer stock 3.2
As i wait my tab to be returned and that day has finally come, i boot up my tab and when i was looking to test my camera the SuperUser app is still there look in to the settings and i was surprised that they didn't update my tab (still on stock 3.1) test the camera at it was much better it way different than the previous to my experience. Much faster and no lag when you move it to one place to another in a fast motion.. then shut down my device to test if i still have thor's bootloader and it is still there..

Using cwm do a full nandroid backup, transfer the backup to microsd, put the microsd into the other Iconia and use cwm to do a nandroid restore.
At least, that's my guess.
well that's a start, I was about to start ripping my hair out over this simple sound issue lol but thanks.

Hmmmmm. Can't you use use a full update.zip and flash a copy of the stock rom? Never tried using a nandroid backup on a system it was not created on - it might work, but it might not, I really am not sure.
But just flashing a full update.zip or installing Acer recovery tool to flash a stock rom sounds easier and more likely to work to me - am I missing something and is this not an option?
I tried flashing two or three times before, sent it into a bootloop, I even tried the Acer update decrypter but my laptop is 32 bit, and until today when I finally decided to post the question is when it occurred to me about possibly transferring it. btw, is there a set destination for the nandroid back up?

Nandroid backups go to the external SD by default (I think) - have you tried using Acer Recovery Installer on the tab with the issue? Assuming you can still boot it and have root you may be able to go back to stock using it.
acer recovery
Tonto the market. Download the new version of Acer recovery installer.install third recovery. Go back into Acer recovery got last box .choose a rom for your location.let it download then install.point and click simple and will fix your issue.if you have failed attempts. You might want to try a different SD card.good luck
This did work for me

Urban geeky blonde like me can do it surely a strong man like yourself willnfigure it out. Giggles
I have tried Acer recovery installer as well, I have 2.3 in fact I tried just a moment ago, and I get boot screen with android the triangle and the exlimation point.
confusion
OK Acer recovery installer is not the recovery just a means to install and work within it and run pre defined scripts.as in there backup and so on
If you are getting that.you need to
1.open Acer recovery installer
2.Install Recovery.the first black box acroos screen.it will askbifnyoubwant to back up stock recoverybdo so.(this is the recovery program only not the system) .
3.boot into recovery and backup your whole tablet.or use the far right black button to d/load and install a new rom from his list.fallow the instructions there clickishly simple
Good luck
So what Acer recovery installer does is replace the stock recovery. To allow you to install non stock decryptedand other. Zip files of course it will install stock recoveries as well.read the Acer recovery install thread under Dev section it's al in there
Again Google luck
OK so here is what I did and it worked like a charm, installed cwm did a custom restore (everything but data) mounted the SD card on other tablet restored and voila I have Dolby mobile back! thank you guys for all the help and info, now I can truly mess with roms and be safe knowing I have a non currupt back up

SWEET! Glad you got it figured out!
Everytime I try to update I get the exclamation mark. Please help.
I would redownload and try again.
I've tried that 4 times. I even did a factory reset and it still doesn't work.
Do a factory rest of ur device (its in the system setting under privacy> Factory Data reset) then run the update.
If that doesnt work, download the OTA package from anyone who has it and put the install.zip file on a empty micro sd card. Insert it and turn the device on while holding down the vol - button.
The device should update and run.
Preferably, if you already have ur device rooted, i would recommend that u download a 3.2 ROM from one of the devs here and use in association with the Acer Recover tool (available from the market place for free) and you won't lose root.
Download A500 specific ROMs here (the stock rom is also listed, but if you do use it, you will lose ALL root access, so make your choice wisely.)
The new acer bootloader for the 3.2 updater still has not been cracked. God speed to those trying.
I have done 2 factory data resets and it still does not work. Can anyone please help?
Assuming you're fully stock and not rooted, take your SD card out.
I just tried it without the sd card in and it didn't work. I am fully stock because I did the factory data reset unless there is other steps to being fully stock. I have used custom roms before.
Maybe you still have cwm installed? If you used another custom roms, mostly sure you still have a modified recovery loader (CWM) uninstalling the Acer Recovery Installer is not enough, you need to restore the stock recovery loader.
Or if you still have cwm recovery, you can try my US 3.2 rooted stock ROM at:

He meant the update.zip not install.zip
Honestly, you should consider just doing this. It is ezterry's stock 3.2 prerooted. I opted to do that instead of messing with the ota just yesterday. Like butter man, like butter. Everything is nice and stock, all of my stuff is still right where I left it. Not to mention it is still rooted.
Thank you everone for you answers but Keninash solved my problem. I forgot to restore the stock recovery loader.

Once you root install this:
Acer Recovery Installer
That will install CWM (recovery).
thanks for you both. i will try all of this on weekend.
but before doing this.. how can i backup my current rom? it is possible? thanks
You should install the Acer recovery installer first, then boot into CWM. When you are in there you will have the option to perform a full backup. This backup function will become your best friend.
thanks.. can't wait for the weekend to do this.
lastly, can anyone give me suggestion on what rom should i try in our opinion? thanks

IMHO the stock based ROMs are the most stable, and trouble free. Head over to the DEV section and pick one out
There are plenty of ROMS to choose from. Some are better than others, and some work better for others. Taboonay seems to be the most popular. I liked Lightspeed because it basically removed EVERYTHING that I didn't need. Citvao seems to be gaining momentium. There is also another guy by the name of THOR who created a custom ROM that incorporates some files from the transformer stock ROM that is pretty good too.
I'd try them all and see what one you like best
Steps to using CWM?
If there's a thread to using CWM please direct me to it.
I have taken a short cut in using it by watching a YouTube video for installing a custom ROM and not learned all the in's and out's of using CWM.
I had installed the OTA HC 3.2 over a rooted 3.1 and lost my rooting as I expected. I decided I wanted to have root capabilites but with HC 3.2, so I found the (Oct 5 )version here and started over again.
I started with the Method 2 approach to install HC 3.2 update (that was already rooted here on this web site) to get to HC 3.0.1. However, initially when I got to installing the HC 3.2 zip it just booted afterwards and then went to a blank screen. So I tried it again only not doing all the clearing of user data, caches, etc., that was mentioned in the YouTube Video for installing a custom ROM. That worked. I now have a Acer Iconia 16 GB A500 rooted with HC 3.2 on it which what I wanted.
I would like to try some other ROMs and still go back if I could but I'm not sure about what exactly has to be cleared every time you load a new ROM. I don't want to have it hang again to a blank screen and maybe screw it up so I can't fix it.
Any directions?
Oh, BTW, when I installed the HC 3.0.1 from Method 2, it was so unstable that I couldn't make a WIFI connection. I had to go right to 3.1 to be able to use WIFI and get Acer Recovery Installer and continue on to installing HC 3.2 rooted.
Thanks

This has been posted in another thread by another member, and I saved it. I just can't remember who posted it again.
It's how I do EVERY flash and NEVER have problems.
"Before installing:
Boot into CWM
1/wipe cache
2/wipe data/factory reset
Advanced Menu:
3/wipe dalvik
4/wipe battery stat
Mount and Storage Menu
5/format (system, data, cache )... leave SD card alone.
install the zip ( new rom ) file !
Once done installing... repeat steps #1 - #4 only ( this is to assured that you are cleaned 110% in regard to the NEW rom that you have just installed )
DO NOT DO THE STEP #5 AFTER THE INSTALLATION !
Reboot system into initial Android greeting screen."
Some would say it's a bit on the "overkill" side, but better safe than sorry.
Thanks for the quick reply.
I think I also found where some of the information I wanted was in:
http://forum.xda-developers.com/showthread.php?t=1205204
I should have done more searching.
Thanks again
Oh, BTW, I have read your other posts on this site and like what you have to say. Also, the last step you have, Step 5, isn't in the YouTube video. Maybe that's where I fouled up and somehow recovered by doing again without some of the clearing. I think I just lucked out and got it working. Initially, without WIFI, I was stuck on how can you install Acer Recovery Installer without going to the "Market"? I had to go to 3.1 to get WIFI and then install it from the Market. I searched the internet with a computer for it, but couldn't find the apk to download so I could move it to a SD card and the Acer. Anyway it's working now and looking forward to more new ROMs and maybe Ice Cream if that's going to be the way to go in the future.

Unfortunately he cannot use Acer Recovery Installer as long as he does not have root and that is why he cannot backup his current configuration i.e. OTA 3.2. Taking the risk of reverting is in first place if he insists on using a custom ROM.

Hi everyone. I had a few questions about flashing new roms on my kindle and was hoping to get some help
1. If I flash a new rom, like cm7, will i need to use titanium back up to save my apps and data. I remember doing this when i flashed a rom for my phone.
2. will flashing to cm7 prevent me from receiving OTA updates that amazon sends out. They just recently sent one a few days ago and the update unrooted the kindle. I wanted to see if I this is something I would have to worry about if i flash to cm7
3. once i do flash to cm7 and say another rom comes out, can i flash straight to the new rom or do i need to flash back to stock then perform the flash for the new rom.. again i remember having to do this when i was changing roms with my phone.
4. does the battery need to be fully charged before flashing
5. If i flash to cm7 then want to go back to back up (amazon stock software with root and gapps) will this make me loose my root access and twrp 2.0
Thanks

1. If you are coming from another rom, then yes. But if you are updating your CM7, then you should probably backup your apps
2. I have had CM7 on my Kindle for like 2 weeks, and have not received an update. So I don't think so.
3. Like I said above in number 1. For example: If you are coming from Cm7 and want to try to flash ICS, then you would first backup your system, then wipe system, data, cache and Dalvik-cache, just to make sure. But if whistlestop releases a new version of Cm7 that fixes the MAC adress, then you would boot into recovery, A backup is optional but is recommended., then wipe cache and Dalvik-cache only, then flash the updated rom on top of it.
4. It says that it is recommended to have a full battery, but I have not yet flashed a rom with a full battery, and I have not occured problems.
5. I think if you get an OTA update after flashing back to stock, then you will probably loose root access again and TWRP. But don't worry, after you get TWRP back, you will still have all your backups.
AWESOME! Thanks for all your help.
one more for you. so i just rooted and installed twrp and did a system back up. then i want to flash cm7. now i am running cm7 and decide to try ics so i do another back up before i flash to ics, will the cm7 override the original back up that i did before flashing cm7 or will i now have 2 different back ups i can restore if i wanted too.

There will be 2 different choices when you go to restore. But the problem is that when you make 2 backups the same day, its hard to tell which is which. So when I make a backup I mount USB with the option and rename the 12-27-11... file to something like CM7-12-27 or something of the sort.

I am in the same camp.
I'm running a rooted 3.2 stock by Timmy Dean.
I'm happy I didn't jump the gun when I Saw the update last night, because it seems I would have truly been screwed.
What I would like to know is if a rooted 3.2 can simply be unrooted. Seems this would the simplest thing to do.
Thanks in advance for any and all help.
Apparently the root doesn't matter. It will just be removed when we install the ota ICS. What worries me is recovery. Because it has to boot into a recovery to install ICS. I had CWM installed then flashed to stock by acer recovery tool in the play store. But when I manually boot into recovery, I get a exclamation point inside a triangle. What recovery are you guys running?

Yeah I think so as well. I flashed stock via the Acer recovery tool but I get nothing when I boot into recovery except what I stated above. I'm not sure if that's right or not.

I was happily running timmydean's rooted 3.2.1 based on the leaked OTA. The ICS upgrade came through and installed just fine. No loss of data and the programs I tried all worked. I was on stock 4.0.4 unrooted.
However, I'm now borked. I rebooted into recovery (Power, Vol -) to see about rooting via the backdoor I'd installed. I had thor's 1.7 Touch CWM recovery installed. I got some weird message that recovery was broken. (Don't recall the exact msg.)
After that, it hung on the "android" screen. Soft-bricked.
So I did a factory reset (Power, vol+, rock screen switch) and ended up back on 3.2.1. Now, the Settings > About > Check update results in the "Network coverage is currently poor. Please move to a location with better coverage to continue." message.
My WiFi is fine, speedtest.net reports a 20 Mbps download. All other apps function well. I'm pulling a DCHP address from my router.
I'm fairly sure this is a badly-worded error message from Acer and actually refers to server overload or some other issue on their end.
Also, installing the latest Acer Iconia Update preps the system for ICS. At one point, installing it allowed the update to proceed, but not to ICS. Uninstalling/reinstalling that update seemed to jog the system at one time.
So I tried wiping data/cache/dalvik and went back to stock 3.2. Same error message when updating. Wiped again and went back to stock 3.0.1. Same error message.
So I'm stuck and am going to give it a few days to see if Acer can sort out their upgrade path. If not, I will probably load CM9 or Thor's ICS ROM. (I do have a Nandroid, so I can get back to where I was pre-ICS.)
All in all, I'm very disappointed in Acer for borking my tablet.

Update: So now a day later, the "poor coverage" message was replaced by an "update available". Installed A500_7.014.03_com_gen1, after reboot, another update A500_7.014.15_com_gen1 installed. I am now on stock 3.2.1.
System update shows "Your device is up to date".
Will see what tomorrow brings, but this is certainly frustrating.

I am in the same camp.
I'm running a rooted 3.2 stock by Timmy Dean.
I'm happy I didn't jump the gun when I Saw the update last night, because it seems I would have truly been screwed.
What I would like to know is if a rooted 3.2 can simply be unrooted. Seems this would the simplest thing to do.
Thanks in advance for any and all help.

Could you guys running the backdoor and still rooted please try this:
1) Try and capture the build no. of the update
2) See if the update will download BUT do not install yet
3) Go to /cache/fota/ and find the zip -
4) copy it to yr external sd
5) post back the build no.
thanks!!!
Procedure for manual install:
1/ rename the file as : update.zip
2/ place the file on the micro sd card
3/ turn off the tablet
4/ press the down volume key and the power button at the same time untill the tablets turns on
5/ the iconia will start the upgrade process by itself.
OR just redownload the update and it install

I had trouble when i reverted to stock in the weekend
and it was a bit of a process to get the OTA's to 3.2.1.
I did manage to hold "full root" but had to revert a couple of times
by putting stock recovery back and using backdoor .
I accidentally factory reset and everything went a bit pear shaped from there...oops!!
Im still waiting for the OTA ICS - getting network coverage error -one good thing
is my partners tab is only 5 days old and still pure factory,
her tab shows same error so at least we know its not root/backdoor problem
So yeah if u gonna take the OTA best to get rid of the backdoor unless you wanna play guinea pig for us all>>>>
dunno why we aint found one of those yet
I dont think you can cause too much of a problem where a "hard reset" pwr/vol -/rotation lock/ combo wont fix...you can then root from there.

I have CWM recovery by thor2002. I think we can't update via ITS unless we flash original recovery

hi 3d0rr!!
i think those of us with the backdoor should be meticulous if/when taking the OTA.
we shouldnt need to unroot and use stock recovery as the ota should get rid of that in the flash. But to ensure a stress free OTA it may pay to do it anyway.
i know you previously told me u were stock gen 1 - but is that from factory, just finished reading a very interesting post regarding the different 'gens' so i for one am sticking with factory build gen :just for the official OTA anyway:

Dibb_nz, I was stock gen 2. I don't wanna take OTA until be sure it's safe. Unless now I know that a hard factory reset may save my tab if something happen.
Can you tell us where did you read that post about 'gens'? I still a little confuse about that

BTW, the network coverage errors seems to be an Acer's error. First I received OTA and a day after that I see that error on my tab. And a couple of hours later I have OTA again. So, don't worry, you should get OTA asap

oh sounds promising, although I just read another post from someone across the ditch in OZ he reckoned acer said they were working on a patch for the problems theyre havin with the first update...who knows
now m8, sorry to confuse you, that wasnt my intention, but i try to make sure that i;m not suggesting things which may end with you or others borkin or brickin yr tab. Ive spent the last few days reading thousands of posts (just like everyone else) thankfully we are fortunate in being able to learn from the mistakes of others I know a bit more about ics than i did 3 days ago let me tell you, lol.
i just finished helpin out a fellow "timmy-ite" stuck with no way of getting in to apx mode to get un-borked...well didnt really help just a sounding board more than anything
he got himself up and running, used the apx tool in my sig, unlocked the bootloader, rooted, flashed custom recovery did a nand and is now running flexreaper - with the tools and knowledge he gained he now has the choice to go back to HC to get the OTA or not....he's one happy camper!!!
Have a read have a read thru the threadhere. ask him a question or two if you want - but dont get too hung up "maybe doing something wrong" you won't be the only person ever to experience that uhh-ohh sinking feeling when you know you shouldnt have just done whatever it was that u just did
Theres always someone round here who will help - usually cos they done the same silly lthings themselves - why ya think i'm always posting
what is the backdoor program you guys talk about?

timmydean's root method also allows you to install a backdoor to re-root after accepting an OTA. You have to manually install it during the rooting process, so you would know if you had it.

timmyDean How to root stock 3.2.1
Summary:
Version V4 is the same as V3 with the only difference being that there is a NEW backdoor script which has some additional features to protect root(#) from getting broken when you do an OTA. I also applied these to this flash image so you wouldn't have to add the additional protection yourself. V4 also has the drivers for XP included. However, when taking an OTA you should also install the backdoor for additional protection. However, you cannot leave the backdoor installed as it turns off sound. So having a little more protection just might save your root in case you take an OTA and forget to install the backdoor.

beat me to it
its a completely stock gen2 rooted and cwm - you can use to unbrick, or go back to stock. only for HC bootloaders though.....
This worked to me

I'm running completely stock, no rom anything. Just flashed updates from users here to update me to the latest HC. I received the ICS update but pretty sure it won't work since I'm rooted and running CWM recovery. What do I need to do to install ICS? thanks

Well my friend, this worked to me... I hope this can help somebody else:
Original ROM: Acer A500 3.2.1 COM_GEN2 Rooted and with CWM using Timmy's method.
1) Go to play market and install Acer Recovery Installer.
2) Open Acer Recovery and verify with recovery do you have. In my case it was CWM recovery by thor2002ro 1.5
3) Install stock recovery. Make a backup of your old recovery when ask.
4) Factory reset: in my case, I made a backup of all my data and used Titanium to backup some apps. Then I harded reset my tab by turning it off and the combo pwd + vol(+) then lock-unlock switch 3 times until I saw "eraing user data" in the top-left corner.
5) turn on the tab and go to google play. Search for acer and install Update enhancement.
6) Go to settings-> about-> system update and aply the OTA update.
You will lost root, but everything should work fine.
To gain root access again, you can follow this thread -> http://forum.xda-developers.com/showthread.php?t=1546593
Now I have rooted stock ICS and I'm so happy
Hey great write up, will try this as soon as I'm off work. Anyway to confirm stock recovery is installed? Because I have done what you said(just the flash stock recovery part) an when I boot into recovery I just get a triangle an exclamation point. Not sure if thats right or not. But I will definitely give this a go since you were running exactly what I'm running now.

yay for 3d0rr you finally took the plunge congrats!!!!!
@tu3218
That download link is no longer available
instead download blackthund3r's one-click-root,
google "ICS Root for Windows"
At step 3 - After you have backed up -
Copy the uid.txt file from the backup folder - this holds your cpu id -
you're probably gonna need it at sum stage
I followed your instructions and it went perfect!!! Rocking ics now. Thanks for the help. First thing I notice, soooo much faster an full of butter.
