Thanks a lot. Successfully rooted my tablet.

One question. After rooting I rebooted into recovery. The stock recovery booted up. Is there a way to keep the CWM recovery flashed during the rooting process?

We can't flash it for now
This exploit only can boot it
We need to unlock the tab to be able to flash something

Hi there,
How did you guys manage to install the MTP device drivers (the one that pops up in Device Manager when you enable the USB debbugging)? I´m on a Windows 7 (32 bits) and the folder we are instructed to download and unzip apparently does not contain the required files/driver.
Any help is appreciated as I can´t manage to pass that initial point.

Thanks in advance,
Mix

EDIT: I eventually got it to install correctly by using the USB Driver package from Acer:

I used the option in the toolkit which installs the drivers. If I remember correctly once you run the .bat file and ACCEPT you are given this option. I used 32 bit version of Win 7 as well.

I just got the Acer Iconia A1-840FHD from a BestBuy and I want root access.
PLEASE somebody find out how!

I am hoping to get Linux up and running to run WINE on it since it is x86 architecture from being Intel.

Edit:Why did they make the name so similar?
I have the "rootable" FHD and yet there is an HD as well.
I hope rooting still works.
Then again,according to the manufacturing date,they have barely been out.

Did you try this guide?
I'm not sure I understand your post and what you want to do.

My product and safety information booklet says FHD on it despite mine only having 1GB of RAM.
Is there a root method working on the A1-840HD?

I may try Kingo since they still get updates and just added an exploit for Nexus Android 4.4.4 as well.
I hope it has support for this device.

Is there any way to step back and put everything as it was without root?

For any reason if we need to send the device to the warranty, this should be like original system state.

Well... I don`t have this tablet but think of buying one and I think that this could be done.

CWM has backup feature so I think that you could try backup current ROM and after you did that then root your device and if the problem pops you load CWM again and then restore original state.

If you already rooted then I think that someone that hasn`t rooted the device could make backup of ROM and upload it somewhere on the Internet.

Many thanks Shreps.

Your image have "RV0ERC02" instead "RV0MRC02". Is this a problem?

It means that my image is older than yours (which make sense, it's not the latest firmware)
But I think you can get some file from it and make your tab working fine again.
If it doesn't work, you can try to full flash the update zip to "downgrade" to a stable version (and then, you should get some OTA updates to get back to the latest version)

Here is some OTA manual download if needed :

Code:
WW_GEN1	AV0K1_RV0MRC02_AV0K1_RV0TRC01	227,47MB	http://global-download.acer.com/GDFiles/Application/OTA/635537141647405935_OTA_Acer_1.0_AV0K1_A.zip

Hi, thanks for the image. Custom recovery fails for me:

assert failed: getprop("ro.product.model") == "A1-840"
Error in /cache/sideload/package.zip
(Status 7)

I tried to find some solution, removed the assert line from the updater script and then custom recovery failed the flash because it couldn't verify whole-file signature. I assume the reason for this is because I modified the updater script within update.zip.

Should the assert line specify "A1-840FHD" as the model? Is this why the first error happens?

I'm trying to flash stock and unroot because, sadly, I think I need to send the device back. Having lots of trouble with the touchscreen.

Here is a full UPDATE zip ROM, flashable via stock Recovery in case something get wrong with /system

http://mon-nuage.net/A1-840FHD/

Check if you're on a WW_GEN1 or GC_GEN1 Region.

Hi, same error here.

After flashing in stock recovery give me the assert failed error.

Its secure to flash the OTA files? I'm curious if they send me the same error that the update.zip. I'm afraid to brick the tab :( .

You're right guys
I didn't tried thoses firmware ZIP and it seems it's for A1-840 (HD) and not for A1-840FHD...

So, I will move the download link (rename the folder).
Sorry for the inconvenience :(

but, @borisgregoris you can still try to push file that are missing for your camera issue.

I will try to upload a full "/system" pull of my tab this weekend, this will not be flashable, but you will have all system files from my A1-840FHD.

I've already copy the missing files to my \system but only in the \app folder. Unfortunately still without camera.
I'm afraid to make things worse.
I don't know if it's secure to make a copy of all your \system structure (without overwriting my files and copying only the missing ones).

You should also set the right permissions and owner to the files like other file in the same directory.
