[Q] Help unrooting? - Acer Iconia A500

How would I go about unrooting this device? I bought it today, and shortly after that I got the 3.2.1 OTA update. Then I rooted by downgrading to 3.0.1. then I installed the apkinstaller and tried to download/install the Acer Recovery apk via the market. I keep getting FC's and android.process.acore errors. everytime I try to use the keyboard to search for the recovery installer, it happens. This is becoming really bothersome. I can't side load it via USB stick or anything. I'm not sure what else to do at this point. I successfully unrooted, but now when i try to download the system update, it gets nearly done and then stalls out. any ideas?

You could just downgrade again back to 3.0.1 and NOT root it and then allow the OTA to roll you back to the future to 3.2.1.

-also Make sure you Completly Wipe (4) + Format (3) (Data, cache, dalvik-cache, battery stats, flexrom)
-then install {Rom}.zip file.
* When you do get to a stable ROM you like, Wipe (3) (Cache, dalvik-cache, battery stats). Then Backup your Rom in CWM (save Folder to PC for backup)
Putting any Rom on top of another is too difficult to troubleshoot and is sloppy.
I'm not saying you did this, just advice!

Right, I appreciate the advice. I'm trying to figure out how to get CWM on the tablet after it's rooted. It was entirely too unstable with all the "acore" errors and FC's to even use the keyboard at the android market. Moderately annoying. In other news, after I did a factory reset, that seemed to fix the stability issues, and then I was able to roll it back to the future, and onto 3.2.1. So after work this evening, I may take another crack at it.
EDIT: But for the money, this thing is entirely worth it.

if you follow instructions to link, you will have HC v3.2.1
-it will not have "Superuser" in apps. so it's not considered Rooted. (it has TD's backdoor)
-it also will still have CWM Recovery. (so it's not entirely stock -stock recovery would have locked bootload)
it's like being half way rooted. it'll be easy to root or change roms (via CWM recovery)
when u turn it in, if they look in Apps menu for "superuser" they won't find and think it's stock.
but if they boot into recovery, they'l know it doesn't have stock recovery.
Rooting Facts:
Gingerbreak -can only Root up to v3.01
IconiaRoot -can only Root up to v3.1
for v3.2, 3.2.1 - TimmyDeans 3.2.1 v3 (backdoor method) or "Flash Custom Rooted ROM"

The update zips are on these forums, you shpuld be able to download and flash to a stable stock version that way, the same wqy you downgraded. From there, if you want root, i recommend downloading acer recovery and iconiaroot and installimg before flashing the downgrade. Thats what i did and i was on the unstable 3.0.1 rom for about 2 minutes before flashing a stable rom with root.

Do a search on here for acer recovery installer, the apk is on XDA... Loasd from pc, install and now you have a rooted A500 with CWM... Load a firmwar to our taste using CWM to get rid of bug ridden unstable 3.01...

[HELP] Lots of problems! Come in and help!

I killed my phone while trying to install a ROM, so I re-flashed a bunch of stuff and it's back. Some problems though - it has Superuser installed still. Even though I did a factory reset, Superuser is still there. When I try to re-root it, it goes through the whole things and gives me "error: device not found". I don't understand why it finds my device in the beginning of the process, but doesn't find it at the end.
1. How do I delete Superuser for good so I can start fresh, and re-root again?
2. What do I do now?
Could you list everything you've done in chronological order starting with the first thing you flashed and ending with the last thing you flashed?

1. I was playing nice with the clean, magic roms, etc, everything was cool.
2. Then I tried to install Blue Breeze the same way and it froze the phone (later found out it was the wrong way to do it).
3. Then I followed the restore to stock thread (flashed system, kernel, etc), and brought it back to life, and Superuser was still installed. I tried to uninstall the root, and that doesn't work either.
So right now I can't uninstall Superuser, OR re-root it again because it just keeps giving me the error: device not found.
If you go into settings and check your internal phone memory...what is it saying you have?
Can you download apps from the market?
I got this same error when the voodoo bit me and gave me the 0.00 internal memory issue.
Try either flashing your stock+root CWM backup (you made one, right?) or the nandroid "stock" image in the forum through CWM.
(Wipe data/cache on reboot in stock recovery and then from the "privacy" menu of your stock settings do a "factory reset".)

1. I have 1.50 GB free.
2. Yes, I can download apps from the market.
3. Where is the stock image located?
4. I did that factory reset like 3 times.
Have you attempted this?
http://forum.xda-developers.com/showthread.php?t=782204
Visit the first thread in this forum for info on stock recovery (including where to find the "stock" nandroid recovery image).
I take it you did not create a CWM recovery backup immediately after rooting your phone?

Android Market - Download Unsuccessful

Hi
I have a rooted Nexus S and have decided to go back to Stock from the ZuluZulu ROM I was using. I downloaded the Stock 2.3.3 and installed through ROM Manager. I wiped cache and dalvik.
On reboot the device was back to standard but it will not let me download all my apps. It has them all attempting to download and then after a while I get a batch noitification saying that the app install was unsuccessful.
Does anyone know what has happened and how it can be fixed?
I have tried to re-download Stock 2.3.3 from other sources but I don't know if the links I am using are broken but they say download unsuccessful.
Network signal is 3G and Wifi has been connected but with the same result...
Hope to hear from someone with the answers soon
Sometimes mass downloading, eg after an auto restore, will cause all apps to fail either installing or downloading. Try one by one.
Delete market cache. Make sure you wiped dalvik/cache at the right time.
If that doesn't fix it flash stock 2.3.4 in zip format via cwm recovery from here.
If that still doesn't fix it try flashing 2.3.X via Odin from here.
Thanks for your reply.
I have tried one by one but no luck.
I no longer have cwm and I have never heard of Odin.
By the looks of it I have lost root access, is that what you think?
Should I try and gain root again and get into cwm?
ok something strange has happened.
I have reflashed the superuser.zip through cwm (finally got it to work through a root method) and the phone is allowing me to download apps.
How can I now revert back to a stock rom without this happening again?
Really odd. I'm battling with the same thing tonight. Trying to go back to stock from CM7.1 nightlies. Wiped everything and tried a few different GRJ22 ROMs but they're all having this same problem.
If your having trouble flashing zip packed Roms via recovery/Rom manager, then you can always try Odin. Found on samfirmware (Firmware and Programs tabs in "Toolbox"). It's overwriting everything, even the bootloader if you want (careful!). You need to download Odin from that page plus the correct firmware for your device. Then just run Odin, apply the correct files (bootloader > bootloader, pda > pda, phone > modem, csc can remain empty (changes carrier info)), double check if only "auto reboot" and "f. reset time" are marked, "start".
> There are more indepth instructions on the forums that should be considered before trying!
I often have this issue too, not sure why.

Tab can't update

Sorry, i couldn't find an answer to this.
Got my Acer A500 less than a week. I've rooted it. Now trying to update Tab latest firmware to 4.010.11 but kept failing. I get the Android bee with the exclaimation mark, or update failed. I've tried unrooting it and then update, but still fail. I didn't leave the SD card in. Should i just do "factory reset", then update, then root it?
Hopefully someone can help me. Here are maybe some helpful info:
-everything stock
-use Iconiaroot 1.3 to root
-done full backup with Acer Recovery Inst. v1.5 & CWM v5.0.0
-Android 3.0.1
-kernel 2.6.36.3-0001-g9*****
-build A500_1.104.02_com_GEN1
-FLEX 02_com-gen1
-device info v 1.0
-SKU wifi
This sort of thing seems to happen with alarming regularity.
A few things to note.
The FOTA update seems to fail most often when CWM is installed (though it was fine for me). Restore your original recovery.
If that doesn't work, unroot and try again.
As a last ditch effort, do a factory reset (you'll lose your data).
Also, make sure you have plenty of storage on your external SD card.

If you use the Acer Recovery Installer, it can restore stock recovery.

sorry FFM, i went into Acer Recovery Inst.
1st temp:
>Restore prev backed-up image
>Install Recovery Image
>Reboot
.....failed (droid w/triangle exclaimation)
2nd temp:
>Acer Recovery Inst.
>Stock USA 1.141.07_com_gen1 recovery
>Install Recovery Image
>Reboot
.....failed (droid w/triangle exclaimation)
On both attempts, it says "flashing tablet", the "Recovery image installed succesfully. But just don't know what to do with it from that point on.
I must be doing something wrong between steps. Trying to seek a step-by-step tutorial to remove CWM as we speak.
You might want to contact Euclid's Brother, The Acer Recovery app is his work so he might be able to help you as to why it's not restoring.

[Q] Iconia a500 reboot

Rom Manager Premiun installed 5.0.1 and when I upgrade to firmware Taboonay 3.0 Iconia my a500 will not boot over tab is in the startup screen is working and only the Manger Rom. Backup did not! Could anyone help me?
you cannot use rom manager to install a rom on the a500, it will not work.
not sure if i understand the next part of your post, i figure your back up won't work and your tablet won't boot up properly, is that right???
do you have custom recovery installed??? clockwork mod or RA??
did you download taboonay rom??
boot into recovery mode (press power button while holding the volume down button)
In the wipe menu -
wipe data (factory reset)
wipe cache
wipe dalvik cache then
install taboonay.
and reboot system.
hopefully things should be working now. Good Luck!!!
As the previous poster said "YOU CANNOT USE ROM MANAGER" for tablets. It is a phone app! Most tablets run on Honeycomb or ICS, and have different memory formatting. Most phones run on GB or Froyo, and they don't mix well.
You will probably need to do this, as it is the easier of steps to take, considering you can;t boot into your Operating system, and have no recovery, not to mention your DevBlk's are probably all FUBAR'd.

He has instructions in the zip file that you need to read. And read them several times.
This should give you a stock rooted 3.2 rom, and I believe will install a recovery system.
If you have any questions about the process, you should post them in TimmyDeans thread where you downloaded the package from, or here in your thread.

[Q] Some help for a nub and ICS + Flashing ROM

Got ICS, OTA (download) installed that no problem, downloaded the acer usb drivers and used ICS Root (blackthund3r). Now i want to install LightSpeed 4.4 (i know theres a newer version) I renamed it update.zip and did the power button + V- button but it says invalid image.
Now im a bit confused cause all this android stuff is new to me, I have the acer recovery installed but im not sure what to do with it. Tried renaming it to recovery.img it says it is flashing but nothing happens.
Kinda lost at what to do or how to get this rom working.... if someone could point me in the right direction it would be sweet

Yep. That was pretty n00b of ya (that little trick only works on signed official roms, and even then, only ify-ify)
Check this thread. It has the tools you need.

You can skip the part about installing an ICS rom and rooting. You already did that. You need to do steps 1, 2, (partial 4) 5 or 6 basically.
Note after you rooted. Look at step 4 and delete the required file like it says, before going to steps 5 or 6. You have an option on which package to use. Personally, I like the exe package. But your choice.
This installs patched b-loader and CWM recovery so you can flash ICS only Roms.
Easy
As you've Acer Recovery why the difficult way ? Just choose "Download / Install Roms, tick Lightspeed 4.4 in the left column, hit download and then install.
(i've version 2.74)
Fast, easy and no problems. I flashed Flexreaper 14 (now replaced by Flexreaper ICS RF1) and i can recommend it, the Rom and the way of flashing it.

Acer recovery is fine if it'll install the patched Bootloader.
However, it doesn't make a user get his UID number, which is essential in case something happens in the future. Without your UID, you're basically toasted Or you're in for the long haul in figuring out how to unbrick a tab.

You can't run that update.zip like you did. You got the error message.
Can you still boot into the 500 Rom? If so, you need to install a CWM Recovery before you can flash custom Roms. Look at the link below for instructions for CWM installation.
If you can't boot into your System, then you will need to do everything again.
You should still have your UID number when you tried to NVFlash the ver3 bootloader (I hope you wrote that number down)
You need to probably re-install the ver3 bootloader again as your attempt to install an update.zip messed things up. You just can't do it that way. So go here;
http://forum.xda-developers.com/show....php?t=1622425
Only this time, follow the instructions. You need to install CWM recovery. This is how to flash Roms, not putting update.zips on the SD card. And BTW, you should delete that update.zip from Your EXT SD Card. It will cause problems.
Also note, in those instructions, if you installed the FULL 500 ROM, you must delete a certain boot-p file before you install CWM Recovery. Or else it will delete it when you reboot the tab. Again, read the instructions.
The above steps install a 500 rom. The 500 DOES NOT have 3g like a 501. This is why you had no 3g. You have to install a 501 ICS Rom after, through CWM Recovery, and, currently, I have the only ICS Rom for the 501. And... it's a Beta release from Acer. But it works ok mostly.
Read the instructions, and understand exactly what you are doing. Also remember, with ver3 ICS Bootloader, YOU CANNOT INSTALL HC BASED ROMS without going back to an HC based bootloader. ICS Roms only. (unless you want to go back to stock).
