go back to stock ics non-rooted? - Acer Iconia A500

I'm probably gonna have to send in my tablet for repair and I've rooted and installed flexreaper's R14 from for ics.I bought the tablet about a month ago it had honeycomb idk if there's a way I can get back to that if not can I get back to stock ics and how can I unroot my tab?

The better way is restore the official rom, you can do it with the downgrade to 3.0.1 unstable.. Which bootloader? HC or ICS?
If you have HC, make the downgrade and then the OTA update or flash a totally stock non-rooted rom (Androonay - vache's site), everything will be stock..
I've done the same 2 days ago e no issues

I think I have the ice boot loader I'm not sure though how can I tell?

Launch Acer Recovery Installer v2.74, it should show which bootloader you have.
If is 3.01 -> HC

Boot loader Version=0.03.12-unl is what it says

So can I go back to stock ics and if so how? Also will they know I rooted if I send in my tab if so I wanna unroot also if any can help me.

I'm wondering the same thing. CWM rev1.3.4 by thor2002ro bootloader version is 3.01 is what I have on mine.

Use one of the TimmyDean APX Packages with your UID and you can flash the unstable 3.0.1 build. Then install Acer Update Enhancement (either from the market or from the Acer website via the APK download) and update to OTA ICS

Similar situation... almost
I am in a very similar situation as the OP except my hardware problem is that both the USB and microUSB have quit on me. Without being able to use APX mode, I'm pretty hosed... right? Anyone want to place an over/under on Acer ignoring the unlocked bootloader and fixing the defective USB module?

You could also use afterOTA found here.
http://forum.xda-developers.com/showthread.php?t=1675939
and it walks you through going completely stock, although why are you sending it in? I have sent a couple things back for screen replacements and they didn't care it was running custom ROMS. But that tool should do the trick for you.

I just got the tab a month ago and my speakers randomly stopped working on me I wanna send it in while I still have warranty

You can fix that. MicroSD
Stick on a MicroSD a stock Acer ICS Leak ROM and flash it in CWM
Then once flashed, it'll automatically flash the stock bootloader and when it boots it'll flash the stock recovery back! Then reboot it and do the Volume Up / rotation lock toggle to wipe all your data off then it's completely stock!

How about you try to be more clear and coherent. Explain what happened in steps.
I really don't understand why you would waste YOUR TIME and Asus' time by RMAing when you still have NvFlash access.
Do you return your computer if a piece of software doesn't work on it?

OK lets try this again...
The left hand section of my screen has stopped working (touch wise)
I am only getting by at the moment thanks to my keyboard dock.
This is the reason i need to RMA my tab.
I was running Prime 1.4 but used NV flash to return to stock but am now without a stock recovery.
Any ideas how to reinstall stock recovery??
When I try to boot into recovery I get an android with a big exclamation mark in the middle of it.

Depending on which nvflash utility u used, nvflash to stock restores stock rom and stock recovery. Try using another nvflash to stock utiltity that is floating around here.

So far I have tried 3 different NVFlash utilities.
One with 3.1, one with 3.2 and now the ICS one. All of which are giving me the same result!
Would it matter not having stock recovery for RMA?

I know for a fact that the nvflash for ics restores the stock recovery, as i used it on my tf. Are u flashing the correct version for your hardware? US, WW, etc? You would be taking a huge risk of doing rma without stock recovery because that will be the smoking gun that you rooted/modded your device, which technically voids your warranty. Go to the development section and look for the thead for easy unroot. See if that restores stock recovery for you.
Edit: looks like that thread got moved to the general section. Look for easiest way to unroot and follow directions.

Correct, i didnt catch that comment.
I dont want to add to the confusion, but isnt that what Stock Recovery looks like, ie Android with exclamation mark
I used nvflash previously to get back to stock rom and recovery and thats what I saw when booting into recovery
This is from another forum

EDIT: Sorry you guys beat me to its "Missed it by THAT MUCH:
Now I feel super special lol thanks for the info!
I thought stock recovery was a simpler version of CWM with some sort menu to navigate.
Now I can pack this POS up and send it back for more repairs.

[Q] Still Have SOD with Flexreaper 11

I, Not at 10 post yet so Here I post,
Can any one help me with SOD on the new Flexreaper 11 ROM. Acer Recovery tool indicates i have 3.01 bootloader. I Had a 3.2 Rom before that worked fine. I Wiped everything and formatted Flexrom and system. First time it went to sleep it would not wake up.
Thanks!

Did you install the Flexreeper new bootloader? This is probably why you still have SOD. If I am not mistaken, Flexreeper has 2 or 3 different versions of bootloader that you need to use. Depending on which version of the rom you want to install.

Thanks for the reply.
I thought that the img file was for people with ICS bootloaders, I thought that I had HC3.0.1
I'm afraid if i flash the ICS img file that I won't beable to get back to HC or that because I have 3.0.1 bootloader that the ICS bootimage file they have there will brick my a500
If you formatted and wiped everything as you were instructed . I am wondering if when you get to the google setup screen something is being restored from the old system.. When it gets to where you setup your google account. Uncheck the backup and restore boxes .
Do not restore any apps or settings from say TI BACKUP. Install only a few apps that you MUST HAVE and know work with google ics. run for a few days and see what happens.
if you still have a issue go back to 3.2 for a week and see if it works. it could be just coincidence that hardware fail-or at the same time as you flashed your tab. ..
just a though thou unlikey
Thanks
I went ahead and tried the ICS Boot.img file after reading some new post in the thread. It worked! Interesting side note, be fore the flash at boot up the display showed:
ACER.
After it was:

You running an a500 or an a501?
Last time I saw the double Acer, was when the leak first came out. The 500 had issues, but not the 501 (except for double acer).
The double Acer is normal. Be glad you don't get the AFU screen like the rest. It's a BETA release, and it has..... issues. Hopefully Acer will release an official build that will do away with a lot of the issues in the near future.

I came from ezterry's acer7.014.14_CUST_ROOT_BBv4_S. I just flashed Flexreaper R11 this morning. I've noticed SOD at least three times today. My bootloader version is 3.01 like in the OP. I noticed he ended up flashing the ICS bootloader. Is this the only known fix? And if so, will ICS bootloaders prevent me from restoring a HC NAND? Thanks.
How do we find our boot loader version? When I do, what does that mean for ROMs I can flash? I have flexreaper r11 and it is consistently SOD badly. :'(

To me a favor and flash the kernel for ICS boot loader users.
Its in the thread , section kernels.
The rom got a auto script for installing the correct boot.img but even for some the ICS boot.img is needed.
Worst that can happen is stuck on Acer logo, if you got that just reboot into recovery and flash the boot.img or kernel for HC boot loader users.
The thing is that even for some people that got HC bootloadr they still need to flash the Kernel for ICS boot loader users, strange yes but no harm in trying.
I'm wondering if something in the cmdline for the LP0 changed in the latest leak causing the kernels packed for the old bootloader to have SoD again.
Also, some of you guys, please don't confuse bootloader with boot.img. They are not the same thing. FLEXREAPER does not contain any bootloaders. It contains 2 different boot.img's and trys to install the correct one based on the bootloader you have.
The bootloader only gets changed if you flash it via nvflash (or flash a stock leak but then it would be locked).
@someone who asked above. if you flash the ICS bootloader(0.03.11-ICS), you would not be able to run HC ROMs, unless you went back to the HC bootloader (3.01).
But apparently, the ICS boot.img is working for some on the old HC bootloader and resolving the SoD issue for them.

Running Rooted 3.2.1 to ICS? Do I unroot?

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

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.

********************************************
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.

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:

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!!!

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.

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.

At step 3 - After you have backed up -
Copy the uid.txt file from the backup folder - this holds your cpu id -

im pretty sure you can only go back to HC if you have a full nandroid backup, im not nearly the most advanced user here thou so ask around a bit before you do anything vast.

[Q] Bootloaders problem

I'm running a FLEXREAPER ROM RF1, with HC 3.01 BL. Everything is OK, but today i wanted to flash a V4 ulocked bootloader, following civato's guide. Everything was OK, except autorotation stopped working... I restored my backup through CWM, with 3.01 BL, and everything became normal again... Can some1 help me to flash a V4 BL?
P.S. also after restore i found another problem? the ACER logo during the loading turned into this any way to fix this?
Civatos guide worked well for me. I too am running RF1 with ics bl v4.
His guide has 2 methods. Are you using the nvflash method or the blackthunder apx tool method?
That screen is a common issue running hc bl's on ics roms, nothing to worry about really.

That display is common on the hc version of boot loader. Its because the kernel needed to be patched to allow root. Also you may see some display flicker on occasion. Normal.
Ver4 boot loader and new ics kernel fixes this..known issues with current ics is auto-rotate. May have to reinstall the from again. Not sure about flexreaper, but the stock ota updates have a lot of this. Usually they reset their tabs. But for you, I would reinstall the rom.

So, if I'm right, i should install a new v4 bootloader and a kernel? But as i remember the flexreaper rom since RF1 has an already patched kernel... In which order should i do this steps? Sry, it's my first android device, so im a newb for now.

No, leave the bootloader alone. It;s ok, and has absolutely no effect on the auto-rotation.
I suggest, re-install the rom again till it works. This is an Acer thing. And it doesn;t effect all tablets. But it seems, the Acer OTA effected a lot of users.
Even on my 501 rom, I had 1 user out of 1000+ downloads, had the same issue. He re-installed the rom a few times, then magically 1 day, it started working correctly.
