[Q] Need to restore after failed update - Acer Iconia A500

I just bought my A500 a couple days ago. I received a couple OTA updates but the last one froze up. After powering down my tablet and bringing it back up the touch is unresponsive.
I've found that if I unplug the power from it I am able to press the power button on and off and that seems to make the touch part work.
However, once I'm in the OS it constantly resets to a black home screen with "Android System" up in the top left corner. Next to that is an icon with a big gear and a small gear with a green belt around them.
The tablet is full stock and I can't enable USB debugging because settings always resets as soon as I get into that area.
I've tried flashing many ROMs using the Power/VOL + recovery mode but none of the ROMs work.
I am assuming that I will need an official ROM in order to actually restore the tablet.
Can anyone help me either track down a stock ROM, ie "update.zip" or help me figure out a way to restore this tablet another way?

Ok, when I plugged in my tablet just now it said USB Debugging was on.
What are my options with pushing an update to the tablet? Are there any methods that would work for me in this case?
Would I be able to root the device at this point and have more recovery options?

Same thing happened to a friend of mine. I followed the directions on this page to fix it:

Basically you are just making it revert to a earlier version.

You are awesome! I've been looking and looking for an image that would work and the one at the bottom of that thread worked like a charm!
Thank you so much for your help!

This rom is not rooted correct? I need to go back to factory to return for warranty.

i didnt flash recovery yet, though i can access the files via usb when its locked at lock screen, so im going to try adb push
Good move
Or you can always toss a full stock ROM image on microSD and flash without custom recovery.

Not sure - never done any full package flashes, only update packages. Pretty sure I've seen a bunch of them around these fourms.
Best of luck - hope you don't have a dead tab.

so far it seems i do, tried a update, and still does the same thing
it would be fine if i didnt have a custom boost animation in the system/media
i still have 12 more days warrenty.
is there a way to delete it via computer?
not sure if anyone knew about the hard reset, i contacted acer and played dumb, though i told them what happened.
i was instructed to
Power down the device
hold Vol Up + Power for 3 sec
continue holding Vol up, and keep switch the screen lock back and forth until "erasing cache" comes up on the acer screen
at which point you stop and let it run its course.
said it would take 30 minutes. i fell asleep, 2hrs later i checked it, still same. recontacted acer, another tech said to do the default hard restart with the push pin
worked like a charm
in process of rooting, installing CWM and making backup lol

Hello ,
Did have the same problem and solved it by flashing the update.zip found on this site.

Did you get it from a local retail location? If so, I would just march back there with my receipt and not give too many details - i was working on a picture and it broke and I have no idea what is wrong, etc - they should just give you a new one.
Have you tried clearing the cache? There is a combo with holding power / volume up when booting and using the rotation lock switch, not quite sure how it is done but i think you just hold both and flip the switch like mad - totally sure I have seen the process posted here somewhere.
If you got it via online order, you still should be able to just return it.
Or call acer - they might be able to work some magic.
Best of luck, hope you get it going or at least get a new one. Really sounds like you have a defective unit, I rooted mine the day after I bought it, have had it for nearly two months and multiple rootings/unrootings/rom flashes and have had no issues at all.

[Q] Desperate Cry for Help :(

Heya XDA - I have no idea WTF happened to my tab. Received notification of a OTA upgrade yesterday, taking me to one of the most recent 3.1 builds (.10 if I remember) - this morning woke up to another OTA update message offering me to go to .11 - accepted, downloaded, tablet hung up during the OTA process.
Now here's where it gets tricky. No matter what I do, when powering up my tablet I get the "Power Off - Shutting down" screen, and a endless spinning circle as the tablet claims to be shutting down. I cannot access any part of the system - all on screen commands are dead, except for the Settings icon in the lower right hand corner - i can click it, enter settings - but the moment I try to select a catagory or change any setting, the system goes right back to the "Power off - Shutting down" screen.
I am way outside the 30 days I can get a trade in - really don't want to have to mail this thing off to Acer.
Here's what I have tried:
One of Vache's full ROM images for my Region - flashed via power and vol process- fails about 1/4 of the way through.
Clearing cache/data - managed to get the vol/power+rotation lock combo going that clears cache and data. Still cannot boot - once I power on no matter what I do I get the "Power Off - Shutting Down" screen.
Tried to do the factory reset via USB keyboard + "Home"??? button? Heard mention this opens up a menu of some sort that I can factory reset from, I have two different USB keyboards and cannot manage to make this happen. Anyone able to explain this? Can this help me?
What's so weird about this - once I power up, I get the "Power Off - Shutting Down" screen no matter what I do. During this time, my battery shows up as %15 - this a500 has been on the charger for hours and hours, overnight last night, was 100% this morning before I applied the OTA update. Even with tablet plugged in, the battery shows as only 15%. What's even weirder - with tablet power off and plugged in, I do not get the red or blue charging light from the power button.
Totally freaking out here, no idea what to do. Anyone able to help?
Edit: When trying to manually flash a update.zip - I am getting the Clockwork Mod (I think?) flash screen - a green droid guy with gears turning. This fails about half way through. I have installed ClockWorkMod before this problem - but cannot enter the clockwork menu by the normal vol/power combo - I am so confused
Edit again: From browsing other posts - seems I am not the only one with this problem. The most recent OTA update failed, every single reboot since then is useless - all I can get is the "Shutting Down.." screen. Trying yet another update.zip via MicroSD to see if I can actually restore my tablet
Edit Yet once more (Problem Resolved!) - no idea how - but after a lot of searching I found a full package with build number 4.010.40_COM_GEN1 - this update.zip flashed with no problems, and my Iconcia is UNBRICKED! Sorry for the panic, everyone
OTA .13 Failure
I have the same problem, but got there by a different path. After many attempts to upgrade to .11 from .7, I downloaded the full file .02 to .11, decrypted and moved update.zip into the external sd card. Used the power / vol- combination and the update to version .11 went on without a hitch. Shortly after that, I received a notice that .13 OTA was available. It appeared to install without a hitch but after it rebooted (automatically) the tablet came back and immediately displayed the never ending Power Off screen described above. I would add that a two gears with a belt icon is sitting in the top left corner and "Android System" is noted beside that icon. I have tried every trick I have found in the forums to fix this:
1. Removed the SD card and shut down the tablet
2. Used power / vol- with portrait rotation lock turned on
3. Put the SD Card (with the .11 update.zip file ) back in and tried 1 and 2 again (no change: never ending power Off)
4. Tried power / vol+ with rotation lock. Saw the cach clear and looked very promising. Came back up with the rotating gears guy, but still went back to Power Off.
As soon as the power button is pressed the power icon goes red and stays there. Looks like the .13 update fools the device into thinking the battery is dean and it tries to shut down but never completes the cycle.

For sure - sorry about the delay on that, was just so excited to be unbricked after a day of futile effort, I needed a break.
Anyway - here's what I have figured out. Somehow during the ota update I received this morning something failed - the tablet rebooted, and regardless of what I did the moment I booted up I would get the powering down notification. System access was not possible. This was on a 100% stock official 3.1 version - even unrooted before letting the update run.
Tried one of the full ROMS from Vache's thread in the dev section, as well as a bunch of other backup images I was able to find. Every single one failed at about 25%.
After a lot of fail - I gave this thread a try:
http://forum.xda-developers.com/showthread.php?t=1187578
"Bricked Tablet...help!"
I used the link on the bottom of page one - the unencrypted update.zip user kjy2010 was kind enough to upload - here is the direct link - http://www.multiupload.com/WCT2FYLMQC
This one worked - put on MicroSD card and flashed via vol/power method - result - 4.10.40_COM_GEN1 - and I am unbricked! Iconiaroot 1.3 worked for getting root after install - slowing getting my tab back to normal now

Nexus 4.3 update failed, "no command"

So i got the new 4.3 update notification on my phone today. Eager to get it i started the installation (battery level was about 90%). After a while the installation went into a constant reboot, always went untill halfway of the progress bar and then phone went off and started again to same screen. I knew it was ****ed up so i went into recovery mode but then it starts to do the update again and i got the "ERROR" message. So i went into recovery again and now i get the "NO COMMAND". I was running 4.2.2 with everything stock, device was not even rooted...
Any ideas?

Unlock your bootloader, and flash the stock 4.3 image manually. Download it from here
https://dl.google.com/dl/android/aosp/occam-jwr66v-factory-08d2b697.tgz
After that, you can relock your bootloader if you want.

I've got very basic knowledge of android so i don't really know what to do... I imagine if i flash the stock manually i will lose all my data? Because in that case i might aswell go to the store and ask a new one since i still have my warranty...

Similar Prob
Hey guys,
I have a similar problem. Tried the upgrade to 4.3 and it stucked.... well now i constantly see the Google-X-symbol and thats all. Tried to unlock the bootloader via developer tools (for later flashing to Stock ROM) but there's no connection. Tried to replug it, etc.
When I start the bootlaoder (via Vol-Down and On-Button) I can choose the options (but recovery is not possible) But hm, the bootloader doesn't seem to be broken.
Can anyone help me? I'm not really a developer (although I work for a software-company) but I already unlocked and rooted devices and I have experiences in changing deep settings.
Help would be great!!! I don't want to sent it to google - I am lost without my S-Phone....
Thanks!
I have a similar issue, I found the update notification on my phone, went ahead with the update and it took ages! The battery was nearly full and the battery fully discharged while it was updating. I was at a friends house so no charger. When I got home I fully charged the phone and switched the phone on and got the nexus cross animation and thats all. I tried to enter recovery mode but got the no command icon.
Any help would be appreciated, I do have experience of rooting and flashing custom roms on my HTC Desire but have not touched the nexus since I got it. So everything on the phone is stock
Heres interesting, My wife tagged me into a facebook post telling peeps my phone was out of order, as she did it, the facebook app on my phone notified me of the tag!! Still got the nexus boot animation showing on the screen!

Ha, that's exactly the same issue.... Thank God I'm not the only one (sorry )
I got the "no command" error after my update this morning. My battery was pretty low, but the phone was docked. I just left the phone alone while I came here to investigate, and it eventually rebooted itself. Then it stuck on the loading X for around 5 minutes, but now it is optimizing my apps. Looks like it is going to work after all.
Mine has been on for a while but its not seeming to play. what mkes no sense is that it is switched on in the background but the nexus animation is the only thing it shows
I'm having the exact issue. I got my update notification this morning and it failed, going into an endless loop. I called google and they didn't know what was happening, so they're sending me a new phone. I don't want to wait for the new one, so I'm trying to fix this one still. I can start the bootloader, but I can't get into recovery. Is there a way to correct this through ADB?

When you get to the screen with "NoCommand" on it.
1. Press and hold power button
2. Then once you pressing the power button, press the Vol - Up
Thats it

Here is the fix for everyone
Ok, I just got off a chat with an Asus rep.
Step 1: Hold the power and volume up/down to get the android with the "start" option
Step 2: Use the volume down to select "recovery mode" It will now power off and power back up with the dead android and "no command" below it
Step 3: While holding the power button TAP, but DO NOT hold the volume up button. You will get an option to wipe all data. Do that.

[Q] Verizon G2 Stuck in Bootloop

Hey Everyone, just got my G2 today and already have a problem. So naturally the first thing I did was root it, and after a few hours researching the nuances of doing that on a VZW model I got that to work. Next I went and downloaded Titanium and moved my backup files onto the phone, and restored my apps no problem. Then I went to restore my system info (just call logs, sms/mms, bluetooth pairings) and rebooted the phone only to get stuck in a bootloop (the VZW animation would just play over and over.) So I powered off the phone thinking something just went wrong with the reboot. When I went to turn it back on I started to get worried...
No matter what key combo I pressed I could not get the phone to power on. I decided to plug it in and thankfully it did come back on, but once again went into the bootloop. So I did some researching and tried every way to reflash the stock VZW firmware, but nothing has worked. I tried the KDZ method mentioned here, but I cannot get the B2CAppSetup.exe program to install (looks like LG has moved or revoked access to csmg.lgmobile.com:9002). So I moved to this post, but I cannot get the LG Flash Tool to start the flashing (when as instructed I unplug the phone and restart it in download mode again and plug it back in the Flash Tool just says "Waiting for Connection" and doesn't do anything.)
At this point I am out of ideas. I have a feeling that since I cannot even power the phone on unless its connected to USB/Power Adapter something is seriously wrong, but I have no idea what Titanium could have restored to cause this.
Any ideas or suggestions would be greatly appreciated.
Did the same thing myself and nearly crapped myself. Here's how I got out of it:
Power down the phone (hold down power button)
Turn on phone by holding power & volume down buttons
When the LG screen comes up, let go of the buttons and then hold them down again
You should then get options to factory reset.
I will say this, I was never able to restore SMS or call logs from Titanium. Doing a few factory resets just made me stop caring.
Thanks for the reply, however no matter what key combo I press I cannot get the phone to power on unless it is plugged into USB/Power Adapter so I cannot get into the stock recovery app.
Any other ideas guys?

This happened to me while flashing as well.
You have to keep trying, the timing of exactly when to release the buttons and press them again is very precise, meaning you don't have much time at all.
It took me several tries to get it back to recovery.
I also only released just the power button, not both,
Good Luck!

Where you able to power your phone up by just pressing the power button (without it connected to anything)? That's what keeps throwing me off about this whole thing, without connecting it to something no matter what button(s) I press the phone simply will not do anything.

So I tried TWRP but ADB could not see the phone. As a last resort I tried the TOT restore method on the computer that I used to root it initially and it actually went through. Once 10B was restored it finally booted back up and OTA'd 11A and I was able to re-root it after that.
Lesson learned, next time I will not try to recover the phone using a difference laptop then I rooted it on.
Thanks for the help and suggestions guys!

HEY! I'm on the d801 as well and I've been where you're at a number of times, unfortunately. But I've always gotten out. Here's the conclusion I've reached. Trying to flash directly back to stock without wiping all the partitions first is what makes the RDTool get stuck. It's like the phone runs out of memory and can't host a full Gig+ of data since your last ROM is in the way. Sorry if I'm wrong but I'm only assuming you didn't wipe everything except the Internal storage. The good thing every time this has happened to me is that your recovery partition should be intact. Mine always is, and we're on the same variant. Another thing, booting back into recovery is not impossible. It's all in the timing it takes from the first time you see the LG logo while holding volume - and the power button, but don't let go. What worked for me was to let the phone cycle between off and boot power states twice until the phone is completely off again. You may even notice the LED indicator flash red. Release your keys if the phone stays off and immediately hold the combo down again until the phone tries to boot again just don't let go of the buttons. Once it powers down again, leave the phone alone for a few minutes. Come back and this time get ready to boot into recovery. The combo button press will initiate boot but don't let go until the next time you see the LG logo flash, then quickly release and depress the vol down power up combo and hold. May take a minute longer than usual but the reset menu should pop up thereafter. Tap power 2 more times and you should back into recovery. It's worked every time for me. Let me know if you're good and whether this helped!
Good Luck,

i had exact same issue that progress stucked on 49%. if you are using 64bit OS, try to flash it with 32bit(x86) OS
good luck

HEY! I'm on the d801 as well and I've been where you're at a number of times, unfortunately. But I've always gotten out. Here's the conclusion I've reached. Trying to flash directly back to stock without wiping all the partitions first is what makes the RDTool get stuck. It's like the phone runs out of memory and can't host a full Gig+ of data since your last ROM is in the way. Sorry if I'm wrong but I'm only assuming you didn't wipe everything except the Internal storage. The good thing every time this has happened to me is that your recovery partition should be intact. Mine always is, and we're on the same variant. Another thing, booting back into recovery is not impossible. It's all in the timing it takes from the first time you see the LG logo while holding volume - and the power button, but don't let go. What worked for me was to let the phone cycle between off and boot power states twice until the phone is completely off again. You may even notice the LED indicator flash red. Release your keys if the phone stays off and immediately hold the combo down again until the phone tries to boot again just don't let go of the buttons. Once it powers down again, leave the phone alone for a few minutes. Come back and this time get ready to boot into recovery. The combo button press will initiate boot but don't let go until the next time you see the LG logo flash, then quickly release and depress the vol down power up combo and hold. May take a minute longer than usual but the reset menu should pop up thereafter. Tap power 2 more times and you should back into recovery. It's worked every time for me. Let me know if you're good and whether this helped!
Good Luck,

OK. So tell me, what ROM were you on, which recovery version and name are you using, why were you flashing back to stock, i.e. were you having problems, what kind. Explain as much as you can in detail. Need to retrace your exact steps to best get you fixed up!

i was using pa4.0 and wanted to go back to stock because i preffered the lg ui. i had twrp 2.6.3.5 i restored my back up of stock but when i rebooted i got into fastboot mode.
twrp wasnt working after i had restored my back up go straight to fastboot was stuck in fastboot until i found a thread explaining how to get out of fastboot and restore download mode.
managed to get download mode working and tried to flash stock with mobile support tool and got the 49 percent error,
my phone never really displayed any progress just says download mode with a white box and blue dots

K, now if you're only seeing the blue dots when you attach by USB your phone to PC, then you're not fully in DL mode to process the kdz. You should see a white wheel in the center of the screen when you connect and a viewing mirror near the base of your phone with ROOTED in red directly below that. And you're sure your PC is detecting your phone? You've the drivers installed? Because when RDT tells you to run the tool, you'll see some binary code in the viewing window I spoke of, the white wheel will turn and below it will be shown the COM port to which you're connected and a solid thin red bar will begin to fill a space in the viewer showing you the progress.
Also, be sure when attempting the first steps I gave you to boot into recovery that you are not USB connected. It won't work.
And, try to remember if your phone was well enough charged, should have been at least 80% full. It happened to me once that I couldn't boot recovery and my phone would go to fastboot like yours until I left it alone to charge and then I repeated the stepsvi laid out to get back into recovery. This part is paramount!
Please READ CAREFULLY
I used to be in your same situation. I thought I had bricked my phone for good. I finally figured it out. Here is my solution from my Thread.

Okay, after 12+ hours of trying every method possible on XDA I finally resolved my issue. I will update the first post just incase any others care or fall into the same dilemma I was in.
The LG Mobile Support tool would not download the firmware and it would NOT ask me for my IMEI to download it either.
So my solution....
***
Installed LG Mobile Support Tool then Installed the LG Drivers. (FROM HERE http://forum.xda-developers.com/showthread.php?t=2471370
BEFORE I connected the phone to the computer. I opened the LG Mobile support tool clicked (Options on the top right).
When the dropped down opened, I clicked the (Upgrade Recovery) option. THEN, is when the prompt opened to ask me what my IMEI is.
Before I entered my IMEI, I connected my phone to the computer in download mode, then proceeded to enter my IMEI and hit OK.
This is when the LG Mobile Support tool SUCCESSFULLY downloaded the latest official LG firmware and installed it.
*** BE AWARE, with the phone connected to the PC, the prompt NEVER appeared to enter my IMEI.
*** But with the phone disconnected, the prompt came up every time. This might be the trick for some people.
*** with the IMEI prompt opened, I then connected the phone , entered the IMEI, then hit OK. BOOM HERPES....
Well I'll polish this up more later. I hope this works for every LG G2 Variant and not just the T-Mobile one (D801)

Sounds good. A full charge can make all the difference. I learnt the hard way! One or more of us will be along should you need further help.
I do hope you get this sorted! I've come back from the brink too many times to not believe you won't.

You are welcome... The first time I did it too my battery was at 28% and I panicked since I got the low battery error.
I could of sworn that my phone officially became a paper weight. My heart dropped.
I'm glad you are up and running with the rest of us!

I know this thread is a bit old, but it saved my butt. Your method worked perfectly. Thank you for this post.
My LG F460 was bricked (error 570), only download mode was working. Esteef method works fine even my pictures and programs was saved. Thanks!
