Did you have 3.2.1 installed or 3.2? Mainly was hoping to use method 2 as it seems more noob proof. Tottaly new to android and dont really get the gist of custom firmware yet. I thought with method 2 their would be less chance of something going wrong.
i had 3.2
i used the following soft: EUUs_SBK_Acer_A501_0.017.01_PA_ATT.exe
i just edit config in the remp folder. i changed uid and model from 501 to 500
Today i bit the bullet and tried method 2 all went smooth no issue now running thors rom on rooted iconia edit note I was on default acer australia rom 3.2.1
ok so after playing with custom roms for full day and not finding one I liked more than the stock I decided to return to stock. I got it done from the 3.2 ota rom from the developer section. Just wondering if I have to do anything else to receive ota updates again. I have used the check for update feature but it says I'm up to date when I know there is a 3.2.1 update available as I had it before I installed the custom from. Is it just a matter of waiting for it?
Anyone here or anywhere else on the web been able to get hold of the stock
3.2.1 update to sideload the update?
ok after spending most of the day reading this thread http://forum.xda-developers.com/showthread.php?t=1113878 and trying to digest all the info gee major brain scrammble looks like I will no longer receive ota updates. My bad should have spent more time reading instead of jumping in head first. So now I can either wait for ota updates to be posted here and manually update or go back to custom roms full time. So looks like I will be going with option 2 I found a thread here that ics is in the works so don't feel so bad bout my major stuff up. Out of interest will Acer restore defaults for a price?
Back to stock and getting ota updates see my post on page 25 http://forum.xda-developers.com/showthread.php?t=1155664
Hi bulcmal, you seem to know how to solve my question:
I own a new ICONIA A500 and after a few moment with it I updated to 3.2 without reading about it and knowing that has a lot of bugs. Now I want to go back to OTA 3.1 so my question is next one:
After I use the second method presented here: http://forum.xda-developers.com/show....php?t=1276227
Can I update to 3.1 freely (using the update function on the settings).
Thanks a lot.
Method 2 downgrade and you have the right room for your country I don't see why it wouldn't work. After you downgrade when it reboots you will get lots of force close don't panic its fine, then shutdown tablet complete remove your micro sd card delete the downgrade rom and copy the stock rom to the sd card( I just used a cheap card reader for this) then reboot while holding down volume button on left side and power button keap holding till small white text appears in upper left of tablet screen. On a side note its very important to test unzip both updates (the downgrade rom and the stock rom) to be sure they are not corrupt if the process fails to unzip either update you could brick your tab. Also both roms will be called update. Zip don't unzip files any further than this other than to test that they can be unzipped without issues. I take no responsibility if things go pear shaped just describing what I did.

I wouldn't risk updating from the settings menu the downgrade rom is very unstable and you may get errors see post above cheers.
Hi, I read the post above and have two more questions:
First:
I bought the tablet on Amazon US. How do I know which rom do I need?
And second:
After I flash the stock rom, the OTA updates will be available?
I am new to this flashing thing so bare with me if my questions are a bit stupid.
Thanks a lot.
Do you think this will work with a USB storage?

I dont know wich stock rom you would need Usally you would search for the rom based on what country you are in. But seeing as you imported it I dont know how it would work. On the other hand if you got ota updates in your country perhaps it is now running your countries firmware. I succesfully got ota updates after doing this.

??? Do you mean can you use usb storage to do the downgrade and the installation of the stock rom? If so I think it only works from the micro sd card slot.
Also guys the 3.2.1 update is currently being rolled out if you dont need root you could always wait for that update it may also fix your issues cheers
how long has the 3.2.1 update been rolling out? still stuck on 3.2 here in melbourne. I got the tablet a week ago and it updated only up to 3.2.
I originally got it early-mid november, then acer pulled the update. It was re released about 2 weeks ago. I am still waiting for it to come back to.
ok, thought i was being left behind. guess i have to be patient lol

Hi everyone,
I'm running a rooted Transformer HC 3.1 and Netformer overclocking kernel.
Today I got an OTA update notification, and the update is already downloaded on my TF. I have chosen to postpone the update since I know it will fail, but I can only do this 3 times.
Questions:
1. Is there a way to cancel the update completely at this point?
2. If I let it try to update I know it will fail, but will the device still be usable normally i.e. exactly like before the attempted update?
3. Is there a way to unroot the TF without wiping the data? I would hate to have to set everything up again.
Thanks for your quick help, it seems that I don't have much time before the forced update.
I'm rooted also,if you go to this thread here and read it from front to back,i think you will find your answer... http://forum.xda-developers.com/showthread.php?t=1171116
I'm gonna wait for a bigger update or a rooted version of this update.

Thanks, I 've read through the whole thread.
I don't think anyone mentioned being able to cancel the update though. Perhaps deleting the downoaded installation file would help, I might try just that...
I own an EEE PAD Transformer TF101 and its got the 8.6.5.21(WW) firmware and I rooted it via Nachoroot and have installed CWM to be able to make full system backups/restores.
Now in the one hand I'm elated a new Android version called ICS is coming soon but have a couple of 'fears' and questions.
-Will the Tegra2 inside the TF101 run ICS just as smooth as Honeycomb ?
-I want to choose the moment ICS gets updated myself and I hate being forced by OTA but am I right that with Nachoroot and CWM installed it won't work anyways so no fears for that ?
-In that case I still keep getting OTA notifications I guess. Is here a tool to switch that off ?
Would it be wise to use OTA Keeper to backup my root or has OTA Keeper got any drawbacks ?
I bet ICS will at first not be rootable anyways right ?

Correct. A rooted device most likely will have OTA disabled. To confirm, just go into Settings -> About Tablet and if you see a Check for System Update link, then OTA is probably still enabled. You may have to put a rebuilt Rom like Krakd or Prime 2.11 to have OTA disabled.
I think that Root will come fairly quickly for ICS considering the Source has been released for a long while. So the guys who look for those root exploits probably already have a nice stash lined up for when devices receive their updates.
Tegra 2 is plenty powerful enough to run ICS, that combined with the amount of Ram you shouldn't be to worried about that.
If you want...hop over to the Development threads and grab the latest ICS port from Paul Burton. That way you can check it out and see how you feel about ICS. Note: Paul's build are still considered early and some things may not work as you want, but that doesn't mean they won't work at all once Asus pushes out the official build or when Paul finishes up his port.
if you do flash paul's ROM please ask any questions in this thread HERE, and not in the dev thread. Also, be sure to read everything before flashing. It isn't quite complete and you will want to go back to HC after you flash.

I checked and the update link still works and I'm sure I will still get OTA notifications
One good thing is that I noticed that since the RESCUE partition is replaced with CWM that OTA will fail when it reboots into rescue mode to install the update.
I am not keen on installing these ROMS that you mentioned since I don't know what is removed etc. compared to the original roms.
I was thinking this:
since I have root access isn't there a way to remove the OTA update service from starting up by using "terminal emulator" from the Android Market and edit the config file or directory where the OTA update notification service gets started ? Anyone knows if this is possible and how ?
I moved /system/UpdateLauncher.apk and Updatelauncher.odex into another map but that didn't stop the notifications and renaming ota.certs isnt wise since the new firmware update file will keep downloading again and again.

okay cool !
Thanks for the Paul Burton tip but I think I just wait until ICS comes available. I bet it won't take long anymore.

Dont screw with the system its just not good news!!!!!!
If you have cwm recovery ota will check and you will know when ics arrives but it wont install because of the custom recovery not because of root as stated above.

Before anybody says to use the search function, I've been looking through the general topics non-stop for one that applies to my situation, and either it slipped through the cracks (likely) or it doesn't exist (not likely).
Basically, my tablet is rooted and unlocked, and I'm on ICS; the first one that had face unlock in it. I'd really like to update my tab to JB, but I need to be pointed toward directions for updating a rooted and unlocked tab. But on top of that, I also need recent instructions, because I know that earlier attempts at getting this thing updated have resulted in lots of bricked tabs.
If anybody could tell me if it's possible to update my tablet to JB right now, I'd appreciate it, and if someone has figured out how to do it, can you please point me toward that thread? I'd really appreciate it.

I'm in the same configuration, custom-ics-rom with twrp recovery on unlocked device.
I believe the first thing to do is enabling NVFLASH, that will make things safer also in the worst cases.
I did that and now hopefully I have an unbrickable device.
I'm a bit confused on how to go forward, I know that there are two versions of twrp, maybe I should install the JB version, booting inside it and then flash the downloaded JB update from ASUS site, or use the twrp for ICS for flashing and after that install the JB version ?
Anyone knows what is the correct option ?

Keep ICS, as JB will cause much trouble especially if you are rooted, trying to OC and is generally slowein my opinion
I prefer to try it anyway, tomorrow I will try flashing, after all if something will go wrong I should be able to recover with nvflash.

Thank you, Grim. That's disappointing to hear about JB, but if you think that my current build is better than that (which makes sense considering I've seen at least one thread about downgrading from JB to ICS), then I will keep my tab on ICS for now, and thank you for your input, I appreciate it.

If you have twrp recovery, can't you download the jb ROM from the Asus site for your region and flash it in? I'm unlocked and that's how I upgraded one version of jb to another, but my ICS to jb was ota, so in your case I can't speak from experience. There is a full upgrade, and root guide in the general section.

I just managed to do what you re looking to achieve.
I m pretty noob so it tok me a whole day to figure it out.
So first download jb update on asus website (pick the right one for ur type of tf300)
Flash it through adb
At that point i got jb installation working but bootloop
So i flashed jb version of twrp (adb)
I then went in recovery and flashed clean rom 2.5 which worked flawlessly
Just for the fun i did factory reset afetrwards and stock jb eventually launched right

I successfully installed jb following the guide on this site, the only thing that was not working was the flashing of the stock rom, neither given options worked (fastboot flash recovery or fastboot flash system) , I discovered that our eepad has a partition nmed staging used for firmware installs. I then flashed with
fastboot flash staging blolb
and all went good.
Btw I find the JB better than ics, more responsive and smoother, and also if it is not yet overcooked.
Hi guys,
I've searched everywhere and can't get a definitive answer on this so here goes -
I'm a noob when it comes to Android, having recently defected from being an Apple Disciple (I got hacked off with iTunes and bored in general with the Daycare Centre which is iOS) and have recently acquired an Acer A700 tablet.
I have installed the JB update OTA and everything is working fine and am chomping at the bit to get it booted, but most of the posts I have read regarding unlocking the bootloader and rooting it relate to ICS.
My questions are -
Does the bootloader process apply regardless of Firmware? (Are there different versions for different Firmwares)
Can anyone point me in the direction of a decent tutorial on how to do this?
What happens regarding a future update? Do I have to revert back to stock and update from there or can i jump from one ROM to another? (I'm assuming that I can't use the OTA updates any more)
Sorry for the long OP and thanks in advance for your answers.

No problem. Seeing you are on JB, then you have a JB bootloader.
You need to go here http://forum.xda-developers.com/showthread.php?t=1953917
And download Vorbeths easyroot2.0. It's for the 700.
You have to unlock your bootloader first, which shouldn't be an issue for you. Easy instructions for that.
Then download his package to a folder on your PC. (not sure, but you may have to download each file individually) Open a command window (shift & right mouse click) and type in whatever his instructions say. Should be painless.
Make sure USB Debugging is turned on first in your tablet (Settings/Developer Options/USB Debugging), and make sure you have the Acer Drivers installed on your PC.
Then connect, wait 30 seconds, and run his batch file.
You should be ok.

Oh yes, one more thing, once you unlock your bootloader, chances are you will not be able to get OTA. And the only way to re-lock the bootloader is to install a stock rom.
Thanks!
Thanks for the reply. I am now the owner of a fully rooted A700!
Had a few issues during unlocking the bootloader. That thing timeouts quick! Also, didn't realise you had to run the .bat file while the tablet was on the Bootloader USB protocol screen. I thought you had to wait until it booted fully into JB.
Anyway, took the plunge and thanks again for your help.

No problem. I thought I mentioned it timed out in about 5 seconds These days I don't remember much
Yeah, I haven't looked at Vorbeth's script, so I don't know which screen he launches it from. With mine for the 701, you can be when the tab is running normal. No difference in the end result though
Happy Hunting!

One last question - do I have to install Clockwork Recovery for re-flashing the stock images or is it just a case of renaming it update. zip and putting it on an SD Card? Any chance you can point me in the right direction of the most recent/stable build? Is it easy to install?
Thanks again.

Well, this is a trouble spot.
If you wish to install a custom rom, then you will need to install CWM. The most recent version.
If you want to try your luck at installing a stock rom, my opinion, is to leave the stock recovery inplace. I haven't had luck in installing stock update.zips, as Acer has made them very specific. So I can't be much help to you in that.
However, you can always flash back to CWM or a stock JB recovery pretty easy. Personally, unless you plan on flashing a custom, I would just leave the stock recovery.

Sometimes "leaked" update appear here in the forums. They are unofficial. And you never know if they improve things, or make things worse. So be careful.

So, just for future reference, how would I go about re-flashing the stock image? I'm assuming it's saved on the tablet in a separate partition?
I've decided to stick with the stock rooted ROM but would like to know how to re-flash for when Key Lime Pie and future updates are released.
And, seeing as how you haven't steered me wrong so far, I though I'd pick your brains one last time.
Hope you don't mind!
Please forgive me if my questions have been answered many times but I really don't know what to look for in the search menu to address my questions.
1. I have rooted my phone and installed Liquid smooth but I went back to stock (still on 4.1.2 TW) and would like to update to at least 4.3 or higher. One issue I'm having is that when the OTA comes through and I go to update it gives me an error. But even before that as I am rooted it boots into TeamWin and wants me to install from there. It has been a while since I've done anything with the boot loader and I'm afraid to install from there and/or if that is wise. (frankly I've forgotten how)
Honestly I just want a quick way to install the update to 4.3 or 4.4 or whatever the next OTA is so that I can move on. I really don't even want to mess with it much right now as my life is way to busy.
2. My search so far has shown me that others are having similar issues but they are saying that the ota update is messing up certain things with their rooted phones (haven't found the answers I'm searching for either). Should I wait on updating? If so, how do I get the ota to stop wanting me to update my phone?
Thank you for any help you can provide.
wouldn't you know, that as soon as I submit this post I find another thread dealing with the same thing... Sorry for the clutter.

Since your life is too busy and you don't want to mess with your phone anymore, your best bet is go back to stock 4.3 which is very good by the way, very stable, smooth and bug free. After so many complaints from my wife I rolled it back to stock 4.3 and she's so happy now.
1. Flash stock MF1 here http://www.androidfilehost.com/?fid=23134718111254196 , just unzip the flash with Odin
2. Your phone should take the 4.3 OTA update and you're home free.

Thanks so much, but now that I've put a little more research into this update I'm seeing that others are having issues with tethering and that would be a serious issue for me.
Also I used twrp to root my phone and did not use odin so I don't know how to flash with odin (or even have the files on my computer) is there a way to us twrp?
It looks like I will need to put a little more time into this than I wanted. Anyway, thanks for the help.

No issue with tethering for me, just root then install wifi tether router.
