So I rooted a couple of days after I got the Tab, left the Stock Rooted Rom and then loaded the Honey Villian Kernel for O/C purposes. Since O/C is the only thing I do with Root, I am thinking of going back to Unrooted.
My question is, in Iconia Root, if I hit the Unroot with the Custom Kernel still installed what happens? or since I do not have a copy of the original Kernel, how can I reinstall it before Unrooting?
Build is Acer_A500_4.010.13_com_gen2
Current Kernel is 2.6.36.4 Honeyvillain- 1.0+
Thanks in advance

Did you not backup using CWM before flashing your custom kernel?
If you made that mistake, all you need to do is get the stock kernel from the build you're currently on, create a CWM flashable file and flash your stock kernel back.
I did make a backup, then screwed up and wiped the External Card it was stored on. I know, such a newbish mistake. Since then, I have other Backups, just not one with the Original Kernel.
thanks a bunch.. will see if I can search out the kernel I need.
Just grab one of the stock 3.2.1 roms in the development section and install it through cwm. That will replace the kernel, then run acer recovery installer from the market to return to stock recovery. After that you can try running iconiaroot to remove superuser or you can just uninstall it from settings/applications. Now you should be good to go.
Here is a link to a non rooted latest version. It installs through cwm. http://forum.xda-developers.com/showthread.php?t=1429199
The problem is, cwm will still be on your tablet so you will have to flash the stock recovery. I don't know where you can get a flashable version of the stock recovery without using Acer recovery installer which of course requires you to be rooted to use. Although the advantage to keeping cwm will be you can still flash a custom rom in the future the disadvantage would be you won't be able to take OTAs because they will fail when the don't find the stock recovery.
So even if I successfully Unroot, I will not be able to take OTA's?
I have the kernel and was just going to flash it back, and Unroot. If I cant take the OTA's then it's not worth the effort.
Thanks for the information.. My tablet is fine the way it is, just figured if I wasn't really using root, I would go back to stock. Not really interested in flashing a Rom as I don't want to reload all the apps and set it back up.
Thanks again, as usual you guys are quick and helpful.

@Alteros - What I am about to say is NOT recommended by 90% of all posters so I expect there to be replies urging you not to do this - HOWEVER - if you install a custom Rom then just wipe the following (1)Cache (2)Dalvic Cache (3)Battery Stats DON'T wipe DATA. When you format just format the following (1)System (2)Cache (3)Flexrom DON'T format DATA.
By doing this you should get back all your Apps. There is a possibility, as other posters will tell you, that you will screw up the new Rom and then have to jump through hoops to get back to Stock. But if you want to take the chance and it works then you will have your new Rom and retain your Apps.

yeah that might work, but he may just to get titianium backup and backup all his apps, if he is going to revert to stock, by flashing a stock rom over a custom rom things might act funny and since he is not rooted only thing he can do is wipe the device and start new
his less headache way of doing things is to leave root and recovery, and use a stock rom. Theres alot of tegra devices out there and who knows how long this community will be kicking out updates long after acer closes support for A500
Thanks to everyone that helped. I ended up loading Thor's 14.2 over the weekend, was not nearly as painful as I thought it would be. So I may try more in the future.
You guys are always quick to respond and helpful.
What I think I learned is that, once you root, you can never go completely stock again. Since there is not a way to get rid of CWM, at least not easily.

I need some help unrooting and returning to stock. I rooted the device using the method of returning back to 3.1 and flashing the unstable rom then installing iconia root then acer recovery to install CWM. After rooting I did not make a backup of my device so I have lost the original rom. This is an Acer Iconia A500 with 8gb internal storage bought from Best Buy on black friday. I've read through many forums in the development area but since I have not posted enough times I can not ask a question there. Any help would be greatly appreciated.

Basically, when you run a full package stock rom, it should put your tablet back into stock condition. This will remove the custom recovery, just like it did when you downgraded.
You can find a list of the stock roms based on region at this link.
http://forum.xda-developers.com/showthread.php?t=1113878
Vache put some instructions there, and it's pretty simple.
Sorry, I'm new, and have the same question.
I am confused, for clarification ....
If you are unrooting and have Clock Work Mod Recovery what do you have to do?
I used Acer Recovery Installer from the market to install clock work mod. If I am unrooting and returning to sock, should I use the option to install "Stock USA 1.41.07_COM_GEN1 recovery" before flashing and then use the power/up button combination? Is it Ok to use Clock Work Mod to install one of the stock roms from the SD card or will Clock Work Mod cause a mess?

Vache has simple instructions on that page. As you read, it says to extract the update.zip file, put it to sd, then hold vol- and pwr. It should flash the rom, That's for the update zip..
However, I would use one of the full set roms.
When the stock rom runs, it should overwrite the CWM recovery, and re-instate the factory bootloader.
Here are the instructions direct from Vache's page for full rom.
"Here are some full packages, updates and EUU firmware from Acer OTA server and from some magical sources.
Full package and updates should be flash via the recovery.
EUU version are working in APX mode with nvflash. (you can enter in APX mode by booting the tablet with Reset / Power pressed)"
Now, what other recovery do you have to flash a full rom?
NOTE: I have not and have no plans to revert to stock. So I've never done this. You may want to post a question also in that thread to see if you can get any extra info.

You could also use the Downgrade tool with the original downgrade images. The original downgrade tool will put back factory recovery and factory stock. This would be everything you need to be totally stock. Once you get to stock, then you can just apply the OTA's if that's what you want. Or are you trying to get to stock and then root?

Yeah, I keep forgetting about your tool.
I think they just want to get back to a stock condition without cwm and root.
You may want to post a link to the tool.
Finally got it. Used the Acer recovery tool to flash Acer stock recovery image and then extracted the update zip from the full package and put it on my SD card (made sure it was the only zip on the card) then redooted into recovery by holding down the volume up key and the power button. Update flashed and all is back to stock. Reasons for doing this were that I could not find a ROM that seemed like it was a real improvement over stock. My favorite would have been Thor's ROM mostly due to the ice cream sandwich tweaks and the ability to clear the recent apps drawer. May go back to root but wanted to know how to get back if necessary. Thanks for all the help.

Glad it worked for you!
Vache should be a touch more clear on "which" recovery to use for the full package
Although it seems people used both CWM and Acer Recovery. (he just states "recovery")
Glad you cleared that up

@sydeu, you probably want to run Acer_A501_4.037.01_EMEA_TMPL. Note this is for the 501 so not sure if you are looking for a 501 or 500 stock rom.
I run it on my 501, and it has svetski lauguage support.
I think you can use any of the EMEA roms. You can unpack or decrypt the roms before flashing, and check the ldb files (system\usr\xt9\databases\ldb\) You should see an ldb that usually starts or contains "Sv". I think these are related to the keyboard, but it will have system support for the language.
Not all roms and updates are listed there, those are just the ones people were able to find. So get the one that's closest to your needs.
I downgraded my unrooted A500 on 3.2 to the "unstable" 3.0.1
I then rooted it and installed CWM.
Then I made a back up on CWM before flashing another rom.
It worked really well except a couple of bugs (No audio on HDMI and reduced battery life)
I know beggars can't be choosers but I would prefer if EVERYTHING worked.
So....I restored my A500 from the backup of 3.0.1 via CWM with a hope to just returning it back to factory settings and returning to an unrooted 3.2
However, when it tries to do the system update it fails.
I have tried the factory reset and then tried again to update via system update but still fails (I get the blue honeycomb bee with exclamation mark)
Can anyone point me in the direction of a stock 3.2 rom that I can flash via CWM?
or even better, one that means I wont lose root???

Thank you but that was the original method I used to downgrade and is the rom that CWm restores to from my back up.
The problem I have is upgrading via the system update.
I am currently trying to do it via a different SD card.....
there are some roms around, but you'll need a good knowledge of search button
Here's one, there are more but keep in mind they are near stock rooted roms: http://forum.xda-developers.com/showthread.php?t=1313757&highlight=stock+rom+rooted&page=1

This happened to me.
You need to install Acer Recovery from Market and flash the Stock recovery before it will let you update with system updates.
Here is a link to stock rom using cwm but it says its not rooted:
http://forum.xda-developers.com/showthread.php?t=1429199
Since this looks like it keeps cwm in place you should be able to download the flashable version of super user and root your device through recovery.
Just do this http://forum.xda-developers.com/showpost.php?p=20680452&postcount=137
It will fix your issues, guarantee it. Just read the instructions in the readme.

From what I understand, Acer Recovery flashes the US version of stock recovery??
My tablet is a UK one. I did try this before a ALMOST bricked it. I managed to recover it using a previous backup I had made.

Apologies if this is a really stupid question, I have tried to search for a solution and found a few replies to other posts but I still don't really understand how to solve my problem.
My phone is rooted, running stock rom and had franco kernel on it.
I wanted to install the 4.3 OTA update so flashed the stock kernel and tried to update, but it failed saying "warning no file_contextsVerifying.. etc etc". I didn't write down the whole error message as I thought that I'd be able to recreate it if needed by trying to update again.
However, I now have stock rom and kernel but am still on 4.2.2 and when I check for updates it tells me that my phone is up to date.
How can I get to stock everything and update OTA without losing any of my apps/data and remaining rooted? Thanks for any help!
You need the stock recovery as well, without it the OTA won't run (has been mentioned hundreds of times before, see the OTA thread in General for more info)

You do if you want to do the process normally (ie. download OTA and flash without having to manually choose it in recovery). And that link goes to the Franco kernel thread, which I'm pretty sure has no bearing here

You can use a custom recovery to do it normally to when you get the notification just click on it. The reason I posted that link is because he had Franco kernel which changes a system file the link shows you how to change it back

So if I'm happy downloading the update on my computer and flashing it via cwm, I wouldn't need stock recovery? Does that mean that in my phones current state (stock rom, stock kernel and cwm) I could just do that to get to 4.3 and wouldn't lose any apps/data? Sorry if the answer to that is obvious...it just didn't like trying to install the ota update.
IMHO if you want to update via OTA you're better off being 100% stock, it will unroot you and there have been issues re-rooting 4.3 unless you know what you're doing. You also need the stock kernel to flash the OTA so you'll need to flash that back before hand. Easiest thing to do is back up your apps, flash the 4.3 factory image, re-root and restore your apps/data
I don't want to have issues re-routing so I guess my safest bet is to just stick with what I have right now?
Basically any rom I try, will boot up to the Home screen and then before I can count to 7 reboot, and this will loop forever unless I shutdown and load the stock rooted rom. As long as I leave my phone off for a period of time the stock rom will work stably and be fine, if I try to go directly into the stock rom after trying any other apps will randomly crash and even the stock rom will be unstable. Often it will reboot randomly, although I will get more time with it before it does. Yes i am clearing Caches in between roms, no that does not make a difference. I'm not sure what i did wrong.
Here's how what I have done so far:
1. Odin flashed from MI9 to MJ7, now running N900VVRUBMJE
2. Rooted phone with Kingo (Installed Root Checker app made sure of rooted status)
3. installed safestrap
4. installed super SU on stock rom (and I install the super SU .zip along with any rom I have flashed)
5. set up safestrap so that the stock rom is on one of the backup slots and custom rom boots from the stock location (this is done so I can have the full amount of available memory on the custom rom.)
I have backups of everything.
Please help me I have been trying to get the Beanstown 106 rom to work on my phone but ANY rom I use (except stock) has the same issue get to home screen and reboot 5-7 seconds later. What did I miss?

Tried a wipe from safestrap and it softbricked the phone, recovering with kies as we speak. I MUST have missed a step somewhere, because a wipe with safestrap should not cause bricking.

What kind of wipe? If you wipe everything from the stock slot, do not reboot recovery.

After the back to stock reflash with kies everything seems stable, I'm most of the way through the setup without a reboot yet!

I would encourage you to leave the stock ROM in the stock slot and put dev ROMs in the other slots.
I'm not sure why that would matter unless Safestrap has an unintended dependency on the contents of /system beyond it's own interception toolkit. As it stands, the Safestrap "recovery" (not really a recovery at all - it is an application running on top of the stock kernel and stock ramdisk) needs to inject it's own interception toolkit onto whatever is in the "stock slot" - be that an actual stock ROM or a dev ROM.
I suppose that means that Safestrap needs to re-install itself after a flash to the stock slot occurs; perhaps there is a bug in there someplace.
good luck
