Hello,
I have a pb with my acer Iconia.
The tablet is blocked on the screen "Android" ...
I tried the button "reset" but nothing better ...
Is there a way to make a hard reset (factory reset) with a combination of buttons ?
Thanks a lot !
PS : My Acer Iconia Tab is "rooted".
Try holding the power key down till the unit shuts off, then let go and hold it down again till it restarts. Good luck.
I've found holding the volume button closest to the corner and power button at the same time forces a restart. Of course, I haven't tried just holding down the power button alone when it's frozen, so the volume button may not be necessary.
I am having the same problem with mine. My widgets started acting weird and disappearing. I thought a reboot might help but now it gets stuck on the Android load screen. I have tried hard reset and holding volume up during reboot. The latter takes to a recovery boot but seems to search on the SD card which doesn't really help. Acer tech support is absolutely worthless and it is too late to return to best buy so now I have to ship it to acer for service. Sucks.
Try this. Plug in a usb keyboard and power on while holding volume down. Keep holding both buttons until you see clearing cache in the upper left and you can then enter a menu by hitting HOME on the keyboard. There is an option to do a factory reset. You will lose all user data by doing this factory reset of cache and data but it may just get your tablet back. There are some other posts on this in dev if you search. Good luck.
maybe.you,both have a bad app that is causing this
try comparing installed apps .might.find what is the.cause

I did this and it will boot now but during setup the setup wizard FCs and starts over. I checked the Dev sections and I didn't see anything on factory resets? I'm running out of options.
I would try a couple times to boot since cache has been cleared, sometimes it will fix itself after the programs have a chance to JIT compile...it is typical in Android to see some FCs after the cache is cleared. If after a couple boots things aren't working their way out then you may have to flash a system image for your build, however this shouldn't be necessary unless you rooted and changed some stuff like uninstalled system apks etc.
What I did before the factory reset was replace the whole /system/app folder ( that I deleted some bloat ) with one that was complete like stock. I got a bunch of FCs, followed by a black screen. So I followed the steps you provided because the symptoms fit.
I've also done multiple restarts and the setup wiizard is still FCing.
this is my build Acer_A500_1.104.02_COM_GEN1 doubt this will help me.

If I were you (note the disclaimer), I would find and flash the complete system.img file for your build (see the [Dev] System Images thread). Once you have the proper system.img for your build in hand, then you can write the system partition in it's entirety. You can find examples of this in the same dev thread.
Cliff's notes:
Use adb to connect via usb and place the the system.img into /mnt/sdcard (adb push command), or you can do this another way if you have access to your storage via USB. It will take some time to copy, several minutes at least.
You will need root to do the rest, but obviously you already do if you overlaid system/apps. Using the adb shell as su, mount the partition as writable and use the dd command within the adb shell to restore the system partition. It will take several minutes to write, so don't panic.
Here is an example of the dd command if your .img is called system.img in /mnt/sdcard:
>adb shell
# su
# dd if=/sdcard/system.img of=/dev/block/mmcblk0p3
# reboot
do i need to try adb i cant get my android market to load it force closes every time, i wished i could just load an factory image from older version and then let it grab the updates and start from fresh, i am rooted which may have been a mistake. i can hook an usb keyboard up hold home key get into recovery but if i put an rom.zip on sd card it doesn't see it.....what am i doing wrong.
Hi There,
I have also the problem that when I booting my tablet it stucks on the Android logo. I have tried to hook up an usb keyboard but he can´t find him. I get the Androidman with a note of exclamation.
Can someone tell me where I did go wrong? If I try it I see the cache messages etc. in het left corner.
My tablet is not rooted.
if you want to do hard reset first of all make sure you have an appropriate upate.zip on you external sd-card preferably use a stock rom.
after you do volume+ (up) and power once it vibrates keep your finger on volume + and toggle the screen switch few times. then let it go it will update.
Thank you for your answer.
I have searched for a update.zip and I have download and ecrypt this file: Acer_A500_1.104.02_1.141.07_COM_GEN1_1305615165779_f0150ee4
If I put this file on my SDcard I still get the androidman with the ! in it.

That file is an incremental update and is ONLY for updating FROM 1.104.02 TO 1.141.07.
If your version doesn't match exactly, the update will fail. You'd be better off grabbing one of the 3.1 OTA updates in the thread in the dev section, as these are full ROMs.
I have tried the HC 3.1 ROM. This ROM was 487 mb but I still get the Androidman with the ! in it.
I have tried the file: Acer_A500_4.010.38_COM_GEN1.
The other files were 47mb
Reformat your SD card, or try a different one.
Locked at the android screen

I have a similar problem. Tried this and was able to do factory reset. However, after that, the same.The tablet is still stuck on the screen "Android" ...
During factory reset, I noticed the following messages on the screen:
E:/dev/block/mmcb1k1 does not exist
E:/dev/block/mmcb1k1 does not exist
E:/dev/block/mmcb1k1 does not exist
E:/dev/block/mmcb1k1 does not exist
E:failed to mount/sdcard
E:can't mount/mnt/sdcard/update.zip
What does this mean? Is there a way to fix it?
Somebody, please help! Thank you!

Try step 2
Also, advice for a hard reset.
Hi folks,
Have tried following the advice below, downloaded: Acer_A500_4.010.38_COM_GEN1.
Added it to my SD card and then tried to boot whilst holding volume down.
It seems temperamental. Sometimes the Android with the ! appears and there's no progress bar. Sometimes the Android with the ! appears and there is a progress bar, but it never makes it past 25%.
I've tried formatting my SD card and redoing it but no joy.
Any suggestions?
Cheers.
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....
Sadly I cannot unlock my T-Mo MyTouch 3G phone..
I have forgotten a numeric passcode to get passed the lockscreen...
it doesn't request a Gmail login to reset password or anything like other android phones... i have the stock unrooted rom.... no custom recovery or anything...
the current stock recovery doesnt allow me to wipe data, cache, update.zip or anything.. it doesnt allow me to select any available commands which is really unusual...
ive tried to flash another recovery via fastboot but unfortunately i have S-ON... i don't know what else to do... i've tried rooting the phone and i've succeeded but theres no point since the lockscreen doesnt allow me to access superuser... this phone has no hardware problems every button works
I FEEL LIKE THERES NO OTHER OPTION If there's a way to have this phone functioning I'd be extremely surprised. Please help!!!
Edit* - in fastboot mode it shows an option to reset phone when pressing the send (call) button... i've tried it twice but it only restarts my phone back to the lockscreen
Home+back+power. (If I remember correctly)
can you clarify on what that's suppose to do??
Clear user data
That only gets you to fastboot mode...
Please give Fastboot info in order to help you by giving you the right RUU for you to install it but it will unroot the phone,will lock the hboot and it will install the htc recovery but this will solve your problem.
Download Fastbootcommander and post here the info that will give you.
If you do what I said then follow the instructions it gives you (I think it says press trackball to erase and power to turn of) then it wipes data and you can set it up again.
It sais you that the recovery has not this option! Please can you tell me the name of the recovery? Amon ra,Clockworkmod,Hero, what??
Here what he said my friend tvall: the current stock recovery doesnt allow me to wipe data, cache, update.zip or anything.. it doesnt allow me to select any available commands which is really unusual...
Step 1: power down completely
Step 2: hold home and end button
Step 3: wait until the warning triangle appears and let go of both buttons
Step 4: press both buttons again
Step 5: scroll down to factory reset
Step 6: once reset, go to reboot
use the trackball to select
I just followed this tutorial https://forum.xda-developers.com/v20/development/h918-recowvery-unlock-v20-root-shell-t3490594
I got root installed TWRP- I did everything, and then I went to flash a ROM and during the setup (AROMA setup)
It just froze I never finished, it it just froze when selecting an option the ROM in question is (WETA 5.0.7 [16th.Jun]
Now what else was there to do.. i waited for a bit and it still was just frozen.
Before I even flashed the ROM I backed up my device.
When I went to reboot. Thinking everything is gonna be fine.
Its now stuck on the LG (Life's Good) screen.
I can't get into TWRP, nor the bootloader...
The only thing I got to was a screen that showed me my IMEI number and another number apart form that I haven't had any success.
Am I doing something wrong? Please help?! Thanks in advance.
1. pull the battery
2. Hold power and volume down
until the lg logo appears
3. Immediately when the lg logo
appears release and repress
the power key
4. You will see a factory reset
screen use the volume keys to
scroll to yes and press power
to select another screen will
appear select yes and hit
power again there may be a
third screen I don't remember
but if there is just hit yes again
5. This does not factory reset it
accesses recovery which in
your case is TWRP so in a
minute you will see the TWRP
logo once you're there restore
your backup or reflash the
ROM.

Ok so I'm just tripping. Thank you very much its so weird with the power button at the back like that. Thanks a million!
Recently I have updated the firmware to 8.1. by using Odin successfully. However, the Internal Storage was reduced to the half only. In trying to fix this, I reflashed it with 'Nand-Erase' option checked (stupidly!). Then everything gone wrong.
- Bootloop (Struck on SAMSUNG logo)
- No recovery
I reflashed without checking 'Nand-Erase' but still not working, bootloop.
Then I installed/flashed TWRP from Odin again. It was successful, but very sadly I can't do anything:
- Unable to restore backup
- No Factory Reset/Wiping Date, Cache etc.
- No Power off
- Unable to Mount
- Internal Storage show 0MB.
Have you ever faced this problem? Can any one help me please. I am really in need of your suggestion and advice.
SOLVED!
After browsing through lots of pages, I found a solution which works for me. Even though my problem has been solved, I will just put the solution here, in case anyone may face the same problem with me. Follow the Steps below...
Reboot into Recovery (Press volume up, home and power button at same time)
Phone will reboot, leave power button but keep holding other 2 buttons.
After you see android/system update installing screen, leave these 2 buttons
Wait for few seconds and phone will show 'no command' then press volume button 3/4times and system recovery will open
with volume keys go to "wipe cache" and press power key.
after that select "wipe data/reset" and press power key.
after that select reboot phone and press power key
now phone will go to Samsung logo screen and you may think that it is again stuck in bootloop
But no, wait for some time->for me it was less than 4-5 min
and you will see the installing apps and other messages on screen
DONE!
Be Happy
Very considerate for you to post that info up for others. Thank you.
