A500 won't boot - Acer Iconia A500

I recently installed the Acer Iconia Phone Disabler app, and promptly forgot the instructions to disabling it before updating. I tried to install Virtuous Picasso, now it's stuck on the Acer logo screen.
I can't even get CWM to boot (tried powering up pressing vol down and power), but no joy.
Any suggestions?

Well you're either booting it wrong or you've written it wrong. You don't power up the device then press the keys you just press volume down and hold power until the device goes into recovery. So basically you power it on with those buttons.
And the brick could be because you didn't wipe the device. did you do it?

I don't think that app is your issue, because that ROM would have re-written those apps anyway.
See the thread from SC2K on how you might be able to get back to boot.

OK, I wasn't doing it right, apparently. My phone is a Samsung Fascinate, when booting it into recovery I can let go of the buttons once it powers on. The difference is the Acer has to have the buttons held down until you actually see the recovery text appear in the upper left corner of the screen.
So anyhow...after doing it properly, I was able to get it to boot into recovery. Thanks for the suggestions. I've got my tablet back on its' feet, and restored (thank you Titanium Backup!)

Glad you've got it fixed.
And yes this tablet can confuse you because you have to hold the button for quite a long time.

How to boot into recovery without adb

I noticed a lot of people having trouble booting into recovery mode from the phone. This is how to do it. With the phone turned off hold the power button +vol down button until you see the "Vibrant" logo on the screen. Once you see the logo, take your finger off the power button but keep pressing the vol down untill you see the recovery image. Ive tried every other way that people have posted and this is the only way I could get it to work. Sorry if this is already posted somewhere else but I couldnt find it. Hope this helps.
Open terminal emulator
Code:
su
reboot recovery
....Or are you not rooted yet?
And you have to hold its BOTH volume buttons not just volume down to boot into recovery.
- Hold both volume buttons
- Press power button
- When vibrant comes up, let go of power but continue to hold the two volume buttons
- Bam Recovery
I always let go of all the buttons when the Vibrant logo comes up, and it goes to recovery just fine.

I can second this. I am my own little vulcan deathgrip to press them all at the same time though, and still be able to release without dropping the phone.
You could also download quick reboot from the market for those already rooted, it has an option to reboot into recovery.

This ... or use the Reboot Into Recovery option from the Clockwork ROM Manager, which I would expect most Vibrant users to have right now if they're rooted.
What if none of this works?
I've a Vibrant (one week old) rooted. Clockwork installed KiNgxKernel-Vib-3-2.6.29.6 etc. However unless I use clockwork I can't get into recovery mode. Would really like to know a working key press combo if possible.
I read somewhere about some Vibrants being hardware locked. Assuming this is true perhaps that's what this phone is.

In Developer options, enable the Advanced Reboot.
The 3 button combo will work, it's just a matter of timing. Remove and replace the battery, hold vol up + home, then power, holding all three, and when it vibrates, let go of power only.
You could also hook up in USB Debugging mode and issue the command:
adb reboot recovery
And if you don't have a developer option go into about phone and tap build number 7 times.

Some people, including myself, cannot get it to work with the standard procedure...the solution is to basically do it twice. Here's a copy/paste of the instructions:
Long press the power button and choose "power off". Give your phone a few seconds to turn off completely. Once it's off, press and hold these 3 buttons at the same time: POWER+VOLUME UP+HOME. Look at the top left of the screen - as soon as you see little blue text saying entering recovery, let go of all buttons immediately...but be ready...if your phone vibrates (it might be trying to reboot normally again), press and hold those same buttons again until you see the blue text again...then let go immediately. Now you will see your recovery!

Cool
CWM recovery only requires you to push the volume up key and then press the power key until the phone vibrates and then let go of the power button only. When the blue lettering appears, let go of the volume up. The home button should only be required with TWRP.

Whatever the reason, that is not the case with my phone and many others. I've read several threads of people having the same issue. I'm not sure if it's an issue with the OUDHS CWM w/ auto-loki or what.
I've never heard of letting go of the power button only while still pressing volume up, but I gave it a try just to see...it did get me into CWM recovery but only after doing it twice, similar to the method I wrote above.
I have tried letting go of both volume up and power (no pressing home at all) and never found a way to get into recovery.
Anyways, it seems there's no harm in pressing the home button either way and it's probably easier than letting go of the power button and still holding volume up...and easier to explain too lol.

My minor issue is that when I boot to recovery (twrp) it get to the twrp splash screen then freeze. Takes me another reboot or two before recovery really launches.
Tried reinstalling recovery and fixing permission, etc.. but same deal. Anyone have thoughts on this?
I boot into recovery all the time but I have to hold volume up and home button.
Bump!
I'm having the same issue. What I did was that I had the CWM recovery installed and tried to reset the flash counter. Now the phone won't boot into the recovery, it just boots up as usual when I press vol up+home+power up. I appreciate any help! :/

Can you get the blue text in the upper left corner of the screen to appear at any time?
In my case, trying to get into recovery via the 3 buttons is a matter of very precise timing if I try pressing all 3 buttons at the same time. The instant I see the blue text I let go of everything and it works. Hold it for even a fraction of a second longer and the blue disappears and it goes into a normal boot. It works much better if I press Vol Up, then add Power, then add Home. I'm doing that sequence fairly quickly but the point is I'm not trying to press 3 buttons at the exact same time.
But I'm using CWM so I don't need the 3rd button...
From a powered-down state I hold Vol Up then Power and hold both through the vibration until the blue text appears and it goes into CWM recovery just fine. There seems to be a bit more leeway in terms of how fast you need to let go this way although I just tested and holding about a half second too long caused it to bounce out of recovery and do a normal boot. Let go immediately when you see the blue.
Phone won't boot..
So after using CASUAL, my phone rebooted, and got stuck on the splash screen with RECOVERY BOOTING.. in the top left corner. I pull the battery, try to do a normal reboot; takes me to the same screen. Trying the 3 button combo for recovery; same thing. Any suggestions?? I am NOT on MF3 Firmware.

Brick Scare: Can't Access Recovery From Hardware - Only From Software

So I have this strange issue. I just tried shutting my tablet down so I can reboot to recovery to flash something. (Mind you, I haven't flashed anything in a few days)
So I shutdown and I can't access recovery. It just wont boot. Vol+, Vol- and Power at the same time. I tried going power first, then volume and vice versa but no dice. My volume buttons and power button work perfectly fine while in the ROM.
Now at this point I was like, "Screw it, I'll boot into the ROM" but no.... It wouldn't even turn on. I tried plugging it in and nothing (~70% battery when shutting it off). Then I plugged it into my computer and it showed "Device driver software was not successfully installed" with a device named "QHSUSB_DLOAD".
Quick Google-ing made me think I bricked the device. I ended up just holding on the power button for a good minute and it finally booted into the ROM. I'm still unable to boot into recovery via Power + Volume Buttons... I have to use an app to boot me into it.
Why? What happened / is happening?
I'm not sure with the N7, but with my SGS III that's what happened when it bricked.

Yeah... very strange. I'm able to get into the bootloader without a problem... only through an app.
Can you attempt to reflash your recovery?

Could you double check you are pressing the right buttons based on these instructions:
[Info] Guide to entering safe mode, bootloader, stock recovery
You are NOT supposed to press 3 buttons, Vol+ and Vol- and Power as you described, rather just 2 buttons depending on whether you want recovery or bootloader.

Well now I feel like a total dimwit.
I guess I was so used to my Galaxy Nexus... I did a Google search on how to access the N7 recovery but I guess I glanced over the instructions too quickly.

Hardware button boot into Recovery with TWRP

Sorry if this post is redundant, but the methods I've seen haven't worked, so I can't be alone. Here is how to boot into TWRP if your phone is boot looping/soft bricked. (info pulled from here, of all places.)
1. Make sure phone is completely powered down.
2. Press and hold the Volume down button and the Power button.
3. When the LG logo is displayed release the Power button only then immediately press and hold the Power button again.
4. Release both buttons when the Factory Hard Reset screen displays.
5. Press the power button three times, like it says. Even though it says it will delete everything, it won't (I can confirm that if you are at least on v2.6.3.2).
6. After a "factory reset processing" appears, you should get the TWRP flash screen, and you are good to go.
Hope this helps someone besides currently frustrated me.
I LOVE YOU! I honestly didn't think this would work but it does and i'm so happy.
just about to make a thread asking how to do this. Glad I searched. way to make you jump through hoops tho.
thanks for this. for me the phone didnt even have to be completely powered off.
i wa sin a sleep of death so i held down power and vol down until lg logo appeared let go and then pressed power again. pressed power 3 more times and it booted into recovery

Hello,
I unfortunately dropped my VS980, cracked the screen, and the digitizer only works on the bottom portion of the screen. I have a new screen coming, which should fix this issue, however I would like to get my data off my phone (pics), but I can't as I have a password (draw a line/shape kind) and without being able to enter this in, it will not connect to my PC as mass storage.
I was hoping to be able to boot into recovery with hardware buttons and get my data that way, not sure if that is possible either, but at least try it. This I found to work to get me to the factory hard reset screen, but I am skeptical to push the power button and have it wipe my data!
I am open to other options to get to my data if anyone has any, including android device manager which is something I have thought of, but not sure if I can reset the security to nothing, or maybe as the bottom portion of my digitizer seems to work, I can enter in a space or a period for a password and enter that in.
Looking for any guidance!
Thanks!
Got it!
Redid the password with android device manager, which got me in, but I didn't even need to do that as I had the brainwave to plug a mouse in with a usb adapter. Works flawlessly, got my data, now just waiting for replacement screen!

steps to enter recovery that worked for my Sprint LG G2 on ZVC firmware.
1) hold power and volume down button till you see LG logo -- quickly release these buttons and
2) immediately hold power and volume up buttons to enter into factory reset menu.
Then 3 presses of power key to confirm wipe and enter TWRP recovery. :good:
I was going mad trying to enter recovery for an hour. It appears like different models/software versions have different key combinations for entering recovery mode.
My phone was stuck at lg logo screen and i didnt have nandroid backup of the phone. so couldn't try the TOT restore method too as i waned my phone data.

The way that let me get into custom recovery is different.
I hold 'vol up+power+vol down' to start from turned off state and keep holding it[Don't leave just keep holding the 3 buttons]. It doesn't show factory reset screen, it get me into TWRP[Custom Rom] directly. I heard 3 buttons gets u in safe mode IDK but I got into proper working TWRP.

if anybody's looking for the information in this thread like i was, and the posted method doesn't work (it did not for me):
1. Power off
2. Hold volume down and power
3a. release both at logo AND press BOTH at logo right after releasing
4a. Enter recovery
You should enter recovery, but if not...
3b. Keep the buttons pressed (your phone might continue into the start animation, but if you keep the buttons press it will return)
4b. The first logo will appear. Release both and press BOTH
5. Enter recovery

this worked omg...thanks a million...
Just wanted to contribute here in case anyone else had tried everything listed in this thread and still was unable to boot into TWRP.
I'm on Sprint, stock, rooted ZVE, and I have TWRP 2.7.
1. Power off phone, wait a few seconds to make sure phone is completely off.
2. Hold power and volume down.
3. As soon as LG logo appears, KEEP holding down power... BUT release volume down and SWITCH to holding volume up.
4. After a few seconds, screen appears saying "Recovery mode" and TWRP opens up after that.

Getting into recovery

How do I do this? The phone is stuck at the boot animation and i just cannot get it to do anything else, no button combo seems to work, i casnt even get it to power down properly. Never had this much trouble with a phone before.
Hi,
Power OFF your phone then:
HOW TO ENTER RECOVERY
Method 1: Hold the power button + volume down button until the LG image appears. Once it does let go of the buttons then immediately push and hold them again until recovery boots.
NOTE: The method above will arrive at the "hard reset" area, but when choosing hard reset, it will take you to CWM (without actually resetting).

Thank You, what a fiddly process!! Now restoring from backup.
^obviously doesn't understand that you cannot power your phone down properly..
Lg is a little tricky.. But.. In order to hard power down, you must hold the power button until you see the phone power off, but don't let go or it will reboot. Keep holding the power button until you see the lg logo and it will then power down completely.
To get to recovery, hold vol down+power until you see the recovery mode loading. You will see the lg splash screen first but just keeping holding the buttons.. No need to let go and then try pressing them again as the post above me stated...

Are you sure it doesn't actually reset? I'm curious ... because Ive got TWRP and just to avoid that I always reboot into recovery from the rom ... and I've just been scared whenever I see that white screen
