Bootloop on an unrooted Iconia - Acer Iconia A500

Couldn't find a thread with precisely same situation - this morning I left my Iconia with WiFi off on standby with plenty of battery left (70ish %), only to just find it powered off. Now when I try to power it on, it stays in the Android boot animation and doesn't go anywhere from there.
And like I said in the title, it isn't rooted or in any other way hacked, so this is really weird. I think a factory reset would make it work, maybe, but if anyone has any other ideas I'd love to hear them before resorting to wiping.

Also I have no idea how to do a factory reset without CWM. Long press reset button doesn't seem to work?

Hold Volume Down while turning Power On?

Nope...it tries to run update.zip

A simple method for wiping is described in this thread.
Alternatively you can connect an USB keyboard, boot to recovery (vol-down + power) and press HOME on the keyboard. This will open a menu where you can select factory reset.

It got stuck at "Erasing cache" but I just shut it down and rebooted, now it started. Thanks a lot. Somehow I think I'm going to root it now and put CWM so I won't have to lose all my data because STOCK ROM crashes for some weird reason and I don't have a backup.

in my opinion u should just go ask for replacement....

You might get more help if you rename your topic title to something more descriptive.
Second, try searching the forum; this has been discussed in numerous threads on both this forum and the developer's section, along with how to fix it.
Try the threads about the update, or dialing a certain code to force it manually (that's where I learned the timing trick to get into stock recovery on the NS). On the screen you're at, try pressing and holding power, then pressing/holding volume up, that should get you into stock recovery.
Also, if you can get into fastboot, you can fastboot flash the CWM recovery back to the device. If you made an nandroid before doing anything, you can at least go back to the device's state before you tried the update.
i could not find anything on this issue on google or here
i tried doing vol up and power, but its still at the screen, and my computer doesnt recognize my phone
use the instruction on the topic to ROOT the phone
http://forum.xda-developers.com/showthread.php?t=875875
and in one of the steps you can use the ADB to push a good ROM back into the phone to be re-flashed
Try just pulling the battery.
If not, you'll have to use fast boot from the SDK. Just follow the howto at the top of this forum to flash original images.
thank you so much!
i locked my bootloader again, and i've been trying to get the 2.3.1 update, but everytime i do try, it freezes at the android warning sign. i also tried installing it via rommanager when i was rooted...whats going on?
any ideas what could be wrong?

Are you able to get into Fastboot?
I wonder if part of your problem is that you relocked the bootloader. (Why'd you do that anyways? No advantage, imo.)
Fastboot oem unlock will completely wipe your phone, I mean WIPE EVERYTHING, including the sdcard (photos, music, some apps' data, etc), but such a wipe might get you back to stock firmware and stock recovery, then at least you could boot up. You could also then reflash CWM.
Before doing that, let's try this if you haven't:
Turn off phone.
Hold vol-up, then press/hold power.
You should then be in fastboot mode.
The timing's critical (on my phone anyways) for this step: Select recovery, and have your hands on the power button and volume button ready to push.
Watch the screen very closely, for a bout a half second or so, the screen will flash a box with an arrow dumping out onto the android dude. While that screen is showing, press/hold the power button, then press/hold the vol up button. Important to do the power button FIRST this time (at least it is on my phone).
You should then be able to get into the stock recovery.
Once there, maybe we can figure out where to go, but we need to know how messed up your phone is at this point.
Once in Recovery, you could try wiping cache if it's an option, then trying to reboot. Worth a shot, but not likely to work.
You could also do the factory reset wipe in there, this one shouldn't wipe your sdcard if there's anything critical/valuable on it. It will reset all your settings and logins and wipe the apps you've installed, though. Again, might let you boot up normally.

Sounds like you'll need to try to do a factory wipe from recovery and then flash a zip of the stock rom (which you'll need to copy to your SD card)
Did forget your own password or buy this one hot?

Probably not a good idea for him to answer that if it's the latter.

Did you try a full wipe of the tablet? Hold down the volume up key and the power button until the tablet vibrates. Release the power button while still holding the volume up key, and slide the screen lock button (next to the volume up key) to the right and then back to the left.
The screen should display 'Erasing Userdata', you can then release the volume key. It should then erase the cache, Acer says it can take 5-10 minutes to complete. The tablet should then reboot, and you may be able to get in from the stock settings.
If the tablets hangs at 'Erasing Cache' for more than 15 minutes, force a power down by holding in the power key. The try the power/volume/lock routine again.

What doesn't work exactly? Did you get an error during installation? Or was installation successful but the problem still exists?

Touch Screen Stopped Working

Hi guys,
My Mrs. Orange SanFran has all of a sudden decided it doesnt want it's screen touched anymore. All the hard buttons are working and can not see any other issues. Seems there are several people who have experienced it but it seems to resolved itselfon a restart but her's isn't, no matter how long I take the battery out or pressing the reset under the battery cover I can't use the screen making it useless.
Any ideas? I stuck a custom Rom of 2.2 on it when first got it but can't remeber which one, maybe modaco Kitchen R12 Rom.
Cheers
Reboot to recovery, Wipe both Dalvik and normal cache, and restart. If that doesn't help, do a factory reset / wipe data, and restart. If that doesn't help re-install the rom.
Thanks for the tip, but I tried to enter recovery by holding down volume key when powering up but a screen breifly loaded that had the small text "android" written upsidedown but then just goes on loop of the screen and the standard screen, can't do anything.
Holding up volume whilst powering on doesn;t do anything and because I can't use the touch screen I can't access any recovery apps through the phone OS.
It's weird cause I've used to recovery mode on phone boot before as first ROM didn't work, so I know the recovery module worked before, no idea why not now. :-s
Could be either bad flash/root or faulty hw. Google "de-bricking a ZTE Blade".
Thanks again. Came across a very thorough article on modaco but unfortunately the phone won't do anything than a normal startup when holding the up volume or up and menu, so can't try any of the suggestions.
The volume buttons do work though as moved the volume in the OS
Just to be sure: you did first press & hold the volume down button, and then press & hold the power button? You have to hold them both down until the recovery menu pops up. I can take even 10 seconds or more.
If everything fails, try TPT flash. It should solve if there is no hardware issue.

Power off While Stuck on Bootloop

Hello guys, been a while, but I got myself into trouble. For a while I had rooted the phone but one time I rebooted and it supposedly no longer had root. Today I got a notification that magisk updated, so I decided to try it. I booted into recovery and tried to flash. Nothing happened. I tried wiping davlik cache and tried again. What ended up happening instead was that the phone was unresponsive. I attempted to reboot, but instead I got stuck in a bootloop.
I realize the most effective way to get out of it is to flash the firmware via Odin, but since I didn't make a backup I want to avoid that if possible. The problem is that other than the soft reboot (power + volume down) I cannot power off the phone to access recovery mode! I've searched and searched, but have only found ways to soft reset, which doesn't help me access recovery mode.
Is there a way to power off the phone while stuck in a bootloop? Or, alternatively, is there a way to boot into recovery while in a bootloop?
It's so frustrating to not be able to something as simple as a battery pull since the phone is sealed. Is there a way to replicate that to be able to power it off?
Any help would be appreciated.
Hold the power button for 10 seconds.

Hold Vol down and power for soft reboot. As soon as the screen goes off to reboot quickly switch to recovery combo (bixby + up + power) it should boot to recovery

What if Vol down and power don't work, adb, fastboot and device manager don't see it, any other combinations tried too, wait for full discharge don't option. Help plz
Did you manage to get out of this?
Im really scared i bricked my phone now. Everything was working fine but after i did a normal reboot it suddenly would not start up.
Screen is black and the only way i can get a response from the phone is the soft restart (vol down + power).
I need to get into recovery somehow so i can restore my nandroid backup but vol up + bixby + power doesnt work (i assume the phone is on and frozen or something?)
I managed to fix my phone. After leaving it for 24 hours the battery was fully drained. After charging again i could boot to twrp and restore my nandroid backup.

Stuck in TWRP recovery after factory reset

Okay so I'm in a bit of a bind, I've been running NSS 6.5 for many months and today I decided to factory reset my phone so I can hand it over to my son. Without thinking, I factory reset from the settings menu and it took me to recovery mode. I immediately tried rebooting the system only to be forced back into recovery. I factory reset from recovery and rebooted and was forced back into recovery. I reflashed the ROM at that point, and rebooted and was forced back into recovery. I'm in a real bind here and I haven't been able to figure out how to get out of this from searching around. I'm really hoping somebody can come through for me here, I would really appreciate the help! Thank you!

Turn off the phone completely. Power on while holding volume and power. Once the lg logo shows let go of the power and press it back down. It should give you the factory reset option. Select yes yes (it won't format just take you to twrp. Once you're in twrp press system (I think that's what it's called - bottom right option). Then select reboot.
