[Q] Hard Reset

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.

Bootloop on an unrooted Iconia

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....

[Q] Froze on 'wiping system'; now can't boot

Hello all. I tried to read as much as I could before posting this. Here is how my phone is:
- Rooted
- TWRP
- Custom ROM
Here is the problem:
I wanted to load a different ROM, so I tried to wipe system, cache, data and Dalvik cache. During the wipe process (wiping system), TWRP froze for about 5 minutes. I had no choice but to force the phone off. Now I can't boot the OS (expected), but I can't seem to get into recovery either. I can hold the volume button up and get to the download mode where I could restore the stock OS, but I have a lot of pictures that I want to keep. Is there any way for me to save my stuff from the internal SD?
Right now, my phone boots to the LG logo and just stays there.

You should have let the wipe finish. On early version of twrp it can take 15 minutes to complete.
Hold the power button for 10 seconds to turn it off. Then power and volume down into the lg logo, release them and then hold them both again. This should take you to a factory reset screen, say y especially to the prompts, 2 or 3 of them. And it will take you into twrp

tdevaughn,
Thank you.I did not think it would take that long, but yes, I have learned my lesson now. When I used the volume and power keys, it takes me to the 'factory hard reset screen'. It asks me if I want to permanently erase user data and reset settings. Is this the screen you expected to see? If I confirm that I want to do that, will it take me to recovery, or will it delete all of my stuff?

If you still have a recovery, it'll take you to the recovery.

Success! Thank you both so much!

[Q] pin incorrect after cache wipe

Posting for a friend here. Running the Verizon note 3 on what I assume is the most up to date stock software.
Basically he informed me that he wiped cache from recovery because his phone "was having issues" after he rebooted his home screen pin unlock is saying he entered the wrong pin. Is there any way short of a factory reset that will fix this. Thanks for your help

We'd need a bit more info but here goes.
If he's pure stock they can try going into download mode and doing a hard reset. Turn off phone and follow these steps.
1) Press and hold the Volume Up + Home + Power buttons at the same time. For about 5 to 8 seconds, the phone will reload.
2) Release all buttons as soon as you see the Samsung Galaxy Note 3 logo.
3) In the Android system recovery mode, use the volume rocker to highlight wipe data/factory reset, and then press the Power button to select.
4) Select Yes — delete all user data
5) Next, select reboot system now.
He'll have to redo his apps and stuff all over again but he'll be into his phone.
If he is rooted and running a custom rom just reboot and hit safestrap recovery button on start up and reflash rom. You are assuming he on just stock software but we aren't 100% sure.

I stated that he was running stock. He is trying to find a way to do this without wiping data as he has information he doesn't have backed up that he doesn't want to loose
Thanks

I don't know what else he can do other than hard resetting the phone. Did he save it to his sd card or internal storage? If it's on his sd card he's fine. If it's on his internal storage I don't know what else to do. I don't think there's any software for that as it's his phone but bypassing the pin lock any other way might be considered phone piracy and I doubt the xda governing bodies will let that be posted here even if something existed. There was some software for the s3 that let you put your imei number back on your phone if you lost it flashing roms but xda had to not let it be posted here as it could have been used to activate a stolen phone. I don't know what else to do to help. He may have to bite the bullet on this one unless someone else knows something I don't.

Issues with System Update

I have a strange issue with System Uupdate and am not sure if it's causeing my phone to be buggy.
If I check my System Updates Tab I get Last System Update: "Software not updated to G935VVRU2APB5" Failed - Mar 29 2016....error code 454
If I then go and check for new system update, I get "Your Samsung ....is up to date. No update is necessary at this time."
If I then check System update history I see "Software updated to G935VVRS2APB4 Mar 19, 2016..."
However when i check about phone my Baseband version is G935VVRU2APB5.
Anyone know what do I do to get this cleared up?
Thanks!

Since there's not really a way that I've seen to wipe cache without root, (you do have ADB but even with we don't have access to those partitions) (to the best of my knowledge) so unfortunately a factory reset is more than likely your only option.

This happened to me also. Glad I'm not the only one.

You can wipe the cache by powering off the phone and then holding down the Volume Up, Home, and Power button until the phone vibrates. Let go of the power button but continue to hold the others. Use the volume buttons to scroll down to "Wipe Cache Partition" and press the Power button.
Hope this helps.

Thanks for the tip. I hate to have to do all this without root. Have a good day!
