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.

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.

todds, Which stock recovery image did you flash? and which update zip did you install after that?
i want to install the european (swedish) everything stock and would really appreciate some 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
cheers
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.

Thanks for the heads up
OK, i have been out of the nook color game for far too long and it seems most of the threads are talking about going from 1.4.1 to 1.4.2. as you can tell, we haven't touched the nook color in a while (OS wise)
basically from what i can remember, while ago, when the NC first came out i rooted and Rom'd it all on the internal memory. it currently has CWM on it (old orange version) and stock 1.2 OS that i installed through CWM.
i tried installing the nookcolor_1_4_2_keepcwm.zip file or whatever it is, and it aborted the install....assuming because it is an older version of CWM?
the only way i could get into CWM was through trying to install the factory 1.4.2 file, once install failed, i could hit the power button and it would bring up CWM.
where can i go from here. i would be completely fine getting rid of CWM all together and just having B&N handle the updates from now since i have a couple of my own toys
ask questions, and i will try to answer them...but like i said, been out of the nook color game for a long time. i am comfortable with flashing stuff through CWM, not cumfortable with ADB nor making a bootable SD card...although i can follow directions so anything is possible.
thanks for you help, and my wife thanks you too.
The way I would go is to install newer CWM then use one of the 1.4.1 updates I posted in this post.
Then let B&N update it to 1.4.2 for you.
Ok, so how would I go about installing a newer CWM? As sad as this sounds I have never installed CWM any other way other than rom manager. And once I get the new CWM and 1.4.1 on there, do I just update by throwing the official release on the root of the internal memory like B&N tells me to or do I have to have the Keep CWM.zip?
Thanks again for all your help..appreciate it

Anyone? The wife is hounding me. Even if I can restore to completely stock she would be happy. How do I do this?
Thanks guys
Well, if you can still boot into a rooted 1.2 and have ROM Manager on there you can use that to flash the latest CWM. If not find the CWM 3.2.0.8 zip and the b & n 1.4.1 zip mentioned above and put them on a sd cad. I then boot into your current CWM and flash the new CWM (unless you did that via Manager) then flash 1.4.1 and call it macaroni.
One thing to remember followoing J5's response is... if you leave CWM setup as recovery... updates will fail.... That's why I have the 1.4.1 with CWM as alternate boot file with the others.

OK, I don't have From manager installed anymore....can I side load that? Also I found the 3.2.0.1 CWM .img file on the clockwork web site. How exactly do I install that. Just flash the .img file?
I really appreciate the help guys

Use winimage32 to write the img file to the uSD card... that creates the bootable CWM uSD.... then put the 1.4.1 files on it and use that to flash to your nook.
1.2 to 1.4.3?
trying to revive old thread prior to launching a new one. I am in similar situation as OP (running 1.2.0 with CWM on emmc). Have no problem going through steps to get this done (been there done that on this old NC which is my sons now, and have an Asus Eeepad I have rooted and played with for about a year as well) including flashable/bootable sd card.
Question is to just confirm the steps to go from 1.2 to latest 1.4.3 and root it again (assuming I'll be using MN5 for that):
- Would I have to unroot and start installing BN updates until 1.4.3??
- Do I have to unroot first or can I just install a BN update to get to 1.4.3 and then run the manualnooter 5.x?
As OP mentioned all I see are steps for moving from 1.4.1 to 1.4.2 or 1.4.3 so wanting to check prior to moving forward.
Thanks.

You can flash the 1.4.3 directly over the old ROM. Just look at my tips thread linked in my signature at item A15. There is a link for a CWM flashable 1.4.3 there. And yes, you use MN 5 to root again.

Thanks Leapinlar, will give it a go per your tips.
I've been using my NC for a couple of years with various ROMs. I've just pre-ordered the Nexus 7 tablet and will be handing over the NC to my parents. It seems very stable with the current ROM of Phiremod 7.2, but I prefer to give them the full stock experience just in case.
I've downloaded the 1.4.3 update directly from B&N and modified the update-script file so that the update can be flashed via CWM. The only thing I want to know is whether it's possible to overclock the NC after I overwrite the emmc with this update? If so, can it be done via a downloadable app, or does it need a different kernel to be flashed? Also, does the stock experience allow downloads of any app from Google Play, or is it a subset of those apps that have been "approved" by B&N?
Thanks.

Look at post 148 in the same thread you got the information for creating cwm flashable stock for information... or check the customizing roms thread in my signature... I provide the information on how to include the OC kernel in stock .. in fact... its in the rar I posted there... just remove the portions you don't want.

Thanks Dizzy. I saw your 1.4.1 image with the OC kernel but skipped over it since it's not the latest B&N stock image. I'm assuming if I flashed your image and then the B&N stock 1.4.3 that it would overwrite the OC kernel, right?

Yes, but that's why I provided the information in the Customizing ROMs thread... you can download 1.4.3 and modify it as outlined and put the OC kernel into that one before flashing it.
Thank you sir. Ran into a little trouble because of having used Wordpad to edit the file - everything was fine after I converted the CR/LF characters to LF using Notepad++.
Okay, I lied. Not everything is perfect just yet. The image flashed just fine (I included everything except the vold.fstab file). However, the Nook setup hangs while trying to enable wi-fi. I'm thinking it may have something to do with dalingrin's wifi driver fix. Unfortunately, I cannot figure out how to get back into CWM in order to restore my previous ROM and copy a modified image without the wifi fix. I've tried all of the key combinations I can think of.. what's the trick? It always goes to the Read Forever logo followed by the Nook logo into the Setup process.

Usually it is hold power and n on boot up. But I have had problems with that lately. You may have to make a boot able CWM SD card.
edit, you probably wiped out CWM on the flash unless you doctored the install zip.

I doctored the zip using the steps here. The uAltImg and uAltRam are the CWM files, aren't they? They get put into the /system partition as part of the update-script file I modified. This happens right before /system and /boot are unmounted, so I don't see how they can be overwritten. What am I missing? Gremlins??
The wifi driver ended up being the issue. After I removed it from the zip and reflashed the modified stock 1.4.3 image, the Nook was able to connect to the Wi-Fi successfully. Thanks all.

Hey guys,
After rooting, I seem to have removed some bloatware that I wasn't supposed to, messing up my JB build. I forgot to do a nandroid backup (is there even a way to do it on the Razr M), I was wondering if there was a way I could restore the stock factory ROM, using RSDLite or something. Thanks.
