[Q] Unstable state

Hello,
my A500 is now in unstable, weird state, i tried to flash ROM update, but i forgot an old update.zip on SD and also that i have no CWM more. My fault of course.
It started to flash again, suddenly stopped. Now if i reboot, i am on my old ROM, but only Power off .. shutting down message appears. I can touch time, settings, but unable anything to do. Message is still there. I tried to press RESET button, no way. I tried to flash it again with rescue Update.zip no way. Just message still there.
Looks like, it wants to shut down, but this never happens from some reason. But why it is again after reboot there, i don't know.
Any advice please ?
Thanks, Ed

Can you install Acer Recovery Installer so you can install CWM from within Acer Recovery Installer?

Try flashing cwm mod using Acer recovery and quickboot to reboot into recovery. If that fails install itsmagic via fastboot or cwm mod 1.3.4 via manual method posted. Don't despair mate you be fine.

I had exactly this problem myself a few days ago...cwm was corrupted and the fix was to download official rom which was chinese and put it onto my external sd card. Then pressing power/volume up forced the update which also reset the cwm and boot sector back to stock. After this I used the official 3.1 rom on this website to update with english version and market app then finally install cwm to use roms.whew it was painful and i cannotremember where i got the chinese rom from...so im only slightly helpful.

There are many stock ROM links on this forum, I don't think he'll have a tough time finding one.
Thanks for sharing your fix for what appears to be the same situation.

Update
I am not able to put there any ROM, my last hope is that chinese, do you have some link on Multiupload (other site are blocked here).
Funny is, that i see lock screen, proper internet connection, mail marks, proper time and Charging still on 15% forever

Update 2
Looks like that battery is wrong, goes to service, thanks all for help and comments

[Q] Lost CWM & Root Access in HC 3.2 ROM. Need Help

Hi,
I updated my A500 from 3.1 stock to Taboonay 2.0 HC 3.2. For some reason I decided to revert back to HC 3.1 Stock but in trying to do so I messed up and lost both CWM and Root Access. Now I can still boot into Taboonay 2.0 HC3.2 but I cannot access CWM and I cannot flash any other ROM as I do not have Root Access. Also due to lack of Root Access I cannot install CWM.
Can someone please help me regain control of my device??? Please!!!

Iconiaroot is for 3.1,Quick answer:Acer Recovery Installer: https://market.android.com/details?id=com.interphaze.AcerRecoveryInstaller&feature=search_result

Acer recovery installer also requires a rooted device to perform all of its functions including installing recovery.

D/load and flash a full rom some of them will work thru reg Acer recovery for your SD card.

Acer recovery needs "root" access....superuser can be seen in the list of apps but it is denying permission to all apps despite setting "allow" to all apps on default!
What to do?
Tried iconia root....."denied root access"
Tried Acer recovery....."needs root access"
CMW can't be booted into as somehow it is not there!
Tried factory data reset......no change in problem!
??
Help/suggestions needed!

Erica's Cure Worked for me!!!
Ok after taking advice from Erica, I downloaded the official full ROM package from http://forum.xda-developers.com/showthread.php?t=1159443 and extracted the update.zip from it and placed it in the root of my external sd card. Switched off the A500 and rebooted it pressing Vol (down) & Power button till white text appeared in top left corner of the screen. A500 then started updating and successfully completed the full ROM install. On completing A500 automatically rebooted and all is good now. I am now on Stock A500 ROM HC3.1. I have not rooted or installed Acer Recovery app yet. I am going to wait for the official HC 3.2 from Acer Malaysia which I think is due on 10th September.
Thank you everyone on this amazing forum for helping fix this issue for me. Hope this solution also works for others having similar issues.

Additional steps to the last procedure
Ok... Last procedure though restored my A500 to Stock HC3.1 but was not allowing the OTA updates. So I copied update.zip from here: http://forum.xda-developers.com/showthread.php?t=1113878. (you must ensure that you download the ROM that is specifically for your device region... mine is Thailand).
I repeated the same procedure as I did before (see last post). After installation completed, and device rebooted. I checked for new updates (from settings menu / About Tablet / Updates). Voila!!! new updates were detected and are downloading now. These are not HC3.2 updates but HC3.1 update patches.
Cheers!

Hi guys,
Okay title might be a little exaggerated haha but...
Recently broke my hand and one handed computing really sucks. So i grabbed my transformer from the closet that I hadn't used in months. It was acting pretty weird, very slow, and just unpleasant to use. I had previously had it rooted and had a kernal and rom on it, but wanted to revert to stock and try ICS. I really forgot how to do everything so I tried to use this guide:
http://theunlockr.com/2011/11/28/how-to-unroot-and-remove-cwm-recovery-on-asus-transformer/
Downloaded both files. and tried to get into clockwork but kept getting a big ! mark. Gooogled around and found that I could download recovery instller from the market. That got me to be able to get into recovery... I did notive that I couldn't get out of recovery and had to do cold boots to get past it. Still tried it though. When I finally got to uploading those files I still couldn't get ouit of recovery and cold booting just freezes.
Can someone PLEASE help me. I really want to be able to use the comptuter without suffering.
I just want to get it working and hopefully get to ICS.
Would not might using a custom rom if there is a stable ICS release u guys recommend.
If someone can step by step me i would be extremely grateful.
Thanks alot.

How did yo install cwm recovery? You mentioned RecoveryInstaller, I hope you didn't use Acer Recovery Installer.
The RecoveryInstaller for the TF is not available on the market. you have a link to the one you use?
or did yo use ROM Manager to install CWM, what version of CWM do you have, ect.

yea i used rom manager sorry
and i think it was 5.5.0.4 cwm

the exact thing happened to me, do you know if your tf is compatible with nvflash?

This *might* help

Running Rooted 3.2.1 to ICS? Do I unroot?

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.
Sent from my Galaxy Nexus using XDA

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:

Dibb_nz, I was stock gen 2. I don't wanna take OTA until be sure it's safe. Unless now I know that a hard factory reset may save my tab if something happen.
Can you tell us where did you read that post about 'gens'? I still a little confuse about that

BTW, the network coverage errors seems to be an Acer's error. First I received OTA and a day after that I see that error on my tab. And a couple of hours later I have OTA again. So, don't worry, you should get OTA asap

oh sounds promising, although I just read another post from someone across the ditch in OZ he reckoned acer said they were working on a patch for the problems theyre havin with the first update...who knows
now m8, sorry to confuse you, that wasnt my intention, but i try to make sure that i;m not suggesting things which may end with you or others borkin or brickin yr tab. Ive spent the last few days reading thousands of posts (just like everyone else) thankfully we are fortunate in being able to learn from the mistakes of others I know a bit more about ics than i did 3 days ago let me tell you, lol.
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!!!
Have a read have a read thru the threadhere. ask him a question or two if you want - but dont get too hung up "maybe doing something wrong" you won't be the only person ever to experience that uhh-ohh sinking feeling when you know you shouldnt have just done whatever it was that u just did

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.
To gain root access again, you can follow this thread -> http://forum.xda-developers.com/showthread.php?t=1546593

Hey great write up, will try this as soon as I'm off work. Anyway to confirm stock recovery is installed? Because I have done what you said(just the flash stock recovery part) an when I boot into recovery I just get a triangle an exclamation point. Not sure if thats right or not. But I will definitely give this a go since you were running exactly what I'm running now.

That download link is no longer available
instead download blackthund3r's one-click-root,
google "ICS Root for Windows"
At step 3 - After you have backed up -
Copy the uid.txt file from the backup folder - this holds your cpu id -
you're probably gonna need it at sum stage

I followed your instructions and it went perfect!!! Rocking ics now. Thanks for the help. First thing I notice, soooo much faster an full of butter.
