How to reset the A500 - Acer Iconia A500

I just got a used A500. How do I do a full master reset so I can make it like I just opened it up new. Thanks guys,

Go to settings>Privacy>factory data reset...

There's also a reset button on your device Or has this button another function?

Yes however I do believe that this does not clear the internal SD storage. I too wonder about the op`s question. How does on completely reset the tablet including the internal sdcard.

If you do this and the previous owner had deleted phone.apk and telephonyprovider.apk from /system/apps, then it'll get stuck at the logo when rebooting. Check to make sure those files are there before doing a factory reset or data wipe.
Also, Check to see what ROM is on it. Is it stock? or is it a custom ROM? If a custom ROM, then to make it new you'd have to install STOCK.
So it comes down to how NEW you want it.
There's a thread that discusses downgrading to 3.01 using nvflash. That's the most sure way of putting back to factory settings, without knowing the exact status of it currently.
The easiest method probably is to just install a custom or stock ROM with a data wipe. But you need to do a little digging to find out if your on the old bootloader or new one and weather or not the tablet is already rooted.

Factory reset makes your phone like new just like how you bought it, if you want it to go faster just apply a lagfix! Voodoo or One click lagfix
I know the lagfix are available which is my second step, but first i want to do a reset, a list of what is lost and kept would be bery helpful.
Thanks

How to reset everything to out of the box?

Just a quick query before I even get my Nexus S ...
Is it possible to completely reset everything to out of the box condition using a similar method to the HTC devices of holding the down button whilst turning on the phone to access the boot loader screen?
I want to know I can return this if necessary after it's been turned on and configured without leaving any trace of use or my data.
have you installed a custom recovery? or are you on the stock recovery? You can turn off your phone, and then while phone is off hold volume up + power . This will get you into bootloater mode, then you can select recovery. Once you are in recovery hold volume up + power, then it will give you recovery settings, from here you can wipe data.

Thanks, I haven't even received the phone yet so until I have had chance to check it out and make sure it suffers none of the issues cropping up here it will be totally stock - no modding whatsoever.
Will the method above set the phone to out of the box condition with no traces of use?
I gather that once a custom recovery has been installed there is no way to remove it at this time, is that right?

Goto Settings, Privacy, select Factory Data Reset.
This will clear all private data off the phone, whether you're rooted or not, whether you have custom recovery or not.
Edit: to your second question, yes, at present, there appears to be no way to remove the custom recovery. They'll figure that out sooner or later.

yes, the above method will reset everything. You can even reset to stock from the phone itself, by going to storage, then clear storage. Then i believe in privacy settings you can wipe phone. At this time, there is no way to go back to stock recovery once a custom recovery is flashed. But eventually google will release the stock recovery images that are flashable through fastboot
Thanks guys!
Been told I can turn the phone on but not make any calls or add anything to memory - not sure how the hell you can try a phone out with that kind of restriction.
As long as I can clear EVERYTHING if I need to return it that's fine!
Ah, good point about the sdcard. In prior phones, I just pulled mine out and moved to the new phone. You will want to wipe the sdcard as part of removing all traces of you on the phone.

There IS no SD card in the Nexus S (not removable anyway) ;-)
I assume the method above will clear the mass memory.

I'm pretty sure, based on past experience with Galaxy S, Nexus One, and HTC EVO 4G, that a Factory Reset from the Settings menu, or from the CWM recovery does not touch the partition that is mounted as /sdcard (whether it's internal or external).
I'm not willing to factory reset my NS at this time to prove the point, though.
In my opinion, to totally reset your phone (for non-rooted), you should:
/Settings/Storage settings/Erase USB storage
/Settings/Privacy settings/Factory data reset
If you're going to take the Recovery method, then you'd
Wipe all data
format sdcard

WARNING: Do not rename the phone or Telephony apk!!!!

WARNING: if you have renamed or deleted the phone and telephony apks, renamed them back or restore them. It appears doing a soft reset while these are missing, will BRICK your A500!!!
Can someone put these two apks here?
I deleted them. But TI cannot restore them.
what do u mean soft reset. are you talking about factory reset.

Yes, like going into settings, Privacy, "Factory data reset"
When the Welcome wizard comes up, you will not be able to get past the "start" button.

be careful that update.zip provided to me removed the market app, and put some markethd thing (japanese I assume), and now I can't seem to figure out how to get the market back haha..
assumng a factory reset might be a bad idea..
I delete the file phone.apk ...
Who could send me the file or put it somewhere ??
Thanks
So we are ok to rename Phone.apk as long as we don't do a factory reset?
I was enjoying the extra battery life by not having that stupid Cell Standby running. Why on earth Acer would leave that there on a non-3G device is beyond me.

i suspect that the extra battery life is a placebo effect. I doubt that the Wifi version would have a 3G radio chip built in and even if it does it's probably not activated. The 'phone.apk' service is probably just idling and not consuming any real battery despite what the system info says. Only way is to do a proper benchmark test to check it.
What about disabling these .apk files? Do you think it will give the same features as if we deleted them?
im going to work on somethings to make this thing work with out deleting or freezing give me a bit

yeah I renamed both and my tab is working just fine...if you say or think a hard reset fails because if it, post logic that makes sense
After doing a factory reset, it boots to the start screen. However you cannot get passed it. The start button does nothing. I think it is trying to find these apks that were renamed or deleted.

Yeah it's not something I would likely do unless I was intending to sell the device, in which case I'd probably manually restore it to stock before running a factory reset. In my experience factory resets generally play havok on "tweaked" devices.
I guess a warning is a warning!
Yesterday, my battery was dead after a full day of moderate use (which is perfectly acceptable). Today, after renaming the two files, I still have half my battery left after 12 hours. Doesn't feel like placebo to me. YMMV...

[Q] anyway to get internal sd data off when stuck in bootloop?

@ mods i realised my mistake in posting this in the wrong section and posted in the right one but people are replying to this one......so please dont delete this just yet
I in my infinite wisdom tried to mod a file on my phone. I did a titanium backup 1st but forgot to move it to my external SD Doh!
So that went wrong and now I'm stuck in a boot loop with only the stock recovery screen. Need to install stock rom and adb not recognized. (Im sure ill figure that) but my main question is, is there some way to recover data from the internal "sd" memory?
I really appreciate any advice anyone can give
I am not sure if I understood your question.. if you have CWM then just access recovery mode and you will have an option to mount the SD and you will be able to access all your files via USB from your PC
?
I don't have cwm . Like I said I only have the stock recovery screens I.e factory reset and download mode.
Do a factory reset, it won't erase your data.
Not sure that would work. It says wipe user data and factory reset so surely it would wipe my data. Plus I don't think that'll work anyway as I changed a file which caused the boot loop so I don't think a factory reset will fix that file.

what info are you trying to get off the device? the sms etc are stored on your data and will be wiped by a reinstall/factory reset
anything on the usb side for storage will not get touched
Factory reset wont clear anything on the internal_sd
thank you.....but
thanks for the replies peeps ill trust your knowledge (and have pressed the thanks button )
got a day off tomorrow so gonna try and get it up and running again,
Question though, being as i buggered up the stock rom wont flashing the new rom (when i figure out how) delete internal data either.
the reason im being carefull is i did some awesome illustrations (imo) for a childrens book im writing so hoping to save those.

it depends on if you use a wipe or non wipe rom, a non wipe wil lkeep qall the data stored on the android system intact but you might get bootloops if it doesnt replace the file you say you deleted
took the plunge......alls good

Thanks Richy99, i took the plunge and followed nasgilani's guide to installing stock rom, i was supprised when it completed that even my home screens etc were as they were before (appart from widgets being blank) and glad to see "as you all said" my data intact.
i shall be more cautious before i start messing with mods next time
basically internal usb storage of 11gb will never be touched when you factory reset nor wil lanything on an external sd card
the only thing that gets wiped is the 1gb internal space for the rom and data on that partition such as sms/email etc
I know this is an old topic but I noticed it wasn't exactly answered.. I'm trying to send mine back to the factory for warranty because the power button no longer functions. I have the stock rom and recovery and I'm stuck in boot loop because I can't execute factory wipe with the power button. I'd like to pull my data off of the internal SD but am unable to fix the bootloop without forcing the wipe.
I know metter is over now, it was just ur worrying, otherwise wiping cache,wiping data from recovery , flashing stock rom (wipe/non wipe) nothing.will erase data on internal memory.
Just for knowledge
aroma file manager is available, which works from recovery, it can work even you device stucked, unable to boot..
Edit ; sometime you feel ashamed, just come to know this is 6month old topic

[Q] Modified Platform.xml most apps crash and phone is unuseable

Hey guys, I'm having a serious problem with my Note 3 running kitkat, I attempted to modify the platform.xml and I don't exactly know what I did but i was attempting to allow apps to write to my external SD card, but I didn't change the permissions on it now the device literally is as about as useful as a brick.
-It will not run apps
-Internet doesn't work
-Various other problems
I've had a look at some other threads but my knowledge on androids is quite little, It was rooted by a friend who didn't exactly explain Rom's for android. So I'm wondering what I can do because I have some important things on my phone I do not want to loose, and from what i'm aware of a factory reset isn't the best option, if there's a way other than factory restoring it, I did see another solution with using ADB I think it was but i'm sure there is another way I can fix it. Note: Cannot browse any files or modify them they're not visible.
Thanks
Edit: Tried a factory restore from the restore menu I had with the root called CWM-base recovery same issue still popped up.
2nd Edit: Fixed the issue wasn't easy(This is for the people that have the same issue) I basically used android debug bridge to install root explorer, just download the android SDK from google and look up a tutorial on how to install apps, I modified the xml file to a stock one I had in the /system before I modified it, due to the apps crashing nothing would open so I couldn't do this, after that I restarted the phone made sure the apps crashed again, this was a good thing that they crashed, all I did after that was a factory reset never lost app data or my text files, everything is working and thank you guys for the help Some of my apps were gone but I had written them down so yeah, it was an annoying issue not exactly an easy fix b ut it works.
Hey. If u perform data wipe in recovery, u do not lose any files from your phone so this should be safe.
Unfortunately I have no idea how to fix the problem with XML file, but u can safely wipe your phone or reflash your rom.

"data wipe in recovery" By this do you mean the volume up + volume down + home till you get to the menu and press the restore? I just read this somewhere sorry for the noob question?
U press home +volume up +power button combo, until it reboots into recovery. Then you select wipe and factory reset or similar option. Just do not perform perform any formats, cause that's what erases your data. fingers crossed!

I pressed that some little blue and yellow writing came up and my phone's screen went black I guess it either ran out of charge or something else i'll just wait and thanks so much for the help.
Always remember to have your phone over 30-40% of battery when u go to recovery to avoid your phone going off when messing with your phone
If u can get your phone to recovery, you can try to copy important files from there to your of and completely wipe everything and flash a new ROM.

So once my phone comes back on I can do a factory reset and hope for the best? I don't really want all of my apps to go or anything i've installed on the actual device, so when I do a factory reset will this remove everything i've got, i'm not entirely sure how i'd copy the files on to my pc because I couldn't browse anything on the device last time i plugged it in after I modified the platform.xml
You will keep your files but all the apps will be removed, so you will need to install them back. Probably you could copy the file you messed up from someone else and try to get tour phone back up but I am not sure how to do it.

Ok thanks a ton for the help, I'm going to see if there's a way to use the adb utility to pull the file I damaged get a stock one and push it, I don't know if it will work but i'll give it a go, or should I just do a factory reset? I'd prefer to keep my apps but if it means I have to wipe them I will.
You can give it a try and then if it doesn't work, do the factory reset
Let us know how u do

Did the factory restore, via the boot thing same issue and the stupid app crashing, I'm puzzled on what to do. Any other solutions I'm concerned my phone is literallly broken now.
Factory reset does only reformat cache, Dalvik and data partition. If you tinkered with your system one and rendered something useless, it won't help you at all to do a factory reset. It just does not touch the normally READ ONLY system. If you wanna fix it, and you have no setting to fix permissions in TWRP/CWM you have to reflash the system, either by reflashing the custom ROM you used from there or by using Odin and flashing the original system back to it. This is why you ALWAYS should have a TWRP (or if you really think about outdated stuff... CWM) FULL backup ready and armed.
