I have updated the samsung galaxy s4 OS from Kitkat to Lollipop using system update. Now I want to hard reset. Does anyone know that after the hard reset Lollipop OS remains or it reverts to Kitkat?

I've already installed macOS Sierra. But I've also performed a "general" cleaning and I suspect some files were gone. Now the whole system is slow, some things doesn't behave the way they used to. Is it possible to download again macOS Sierra from AppStore and simple reinstall it? I mean, install macOS Sierra over macOS Sierra that is already up and running (not so well...). Thanks a lot for your help.

How can I factory reset my Kubuntu and return it to new-like state, without reinstalling it? (I am having problems reinstalling the OS.)

I have a Samsung Galaxy S4. Is there a way in Android or an app that can take ? I.e. have the raw camera data to process in a program like Photoshop. I am using Android 4.2.2.

I'm in the market for a new Smartphone. Except for iPhone's, I'm new in the field and probably have some misconceptions.  My first choice was the Google Nexus S, but I was offered a great deal on the Samsung S Galaxy II (i9100). The only issue is that I read that it came with an "enhanced" version of Android. Being familiar with PC's, I know that these enhancements are almost always bloatware: I always do a clean install of Windows to get rid of it.  My question is fairly simple: is this possible to use the stock Google Android OS on the Samsung S Galaxy II (i9100)? That was the killer feature of the Nexus S for me: coming directly from Google, easily upgradable. Would that be possible and if yes, how?  Thank you for enlightening me.

I was making some tests on my android phone and I accidentally deleted the launcher from the system partition and I forgot to copy the new one to the system partition again, and the phone doesn't show anything, just the status bar and I can't enter or run anything.   I tryed to send the launcher's apk using bluetooth, but neither other android phone nor windows 8.1 can't send any file to the phone, even if the phone is paired with both devices.  Is there any way to run the Play Store to install the launcher or to install the launcher from the SD card?  Thanks a lot.

After upgrade of any app - apps move back from SD Card to phone memory.  After that, to save phone memory, I have to move upgraded app back to SD card.   Is any possibility to avoid this because it is very annoying?  I have Android 5.0.2 on Motorola E second gen phone.

So, yesterday my phone took a serious tumble.  It is now essentially useless, as the screen either fails to turn on, or when it does, there is nothing useful to see (just lines of primary colors, mostly).  I believe (from the fact that it still chirps at me when emails come in, etc), that the phone is still functional, otherwise.  I would like to perform a full system dump, so that I can get off any files from the phone (a TMobile SGS2 (hercules) running slimrom 4.3 build 1).  The sdcard probably isn't important, as I can just pull it, but the phone's own internal storage I should like to get a copy of.  When I plug the phone into a usb port, it 'mounts' the usb via MTP, and I can see all the files.  Unfortunately, when I do a select all | copy | paste operation, the paste op dies before transferring all files.  I've tried a couple other ADB shell operations, in hope of flipping regular USB mounting on, but nothing has worked.  Any ideas how I can get a full dump of my poor phone's contents?  Edit  Currently running a adb pull /sdcard/ ... Its copying files presently, but its too early to tell if its going to get evertying I'm expecting.  Edit #2  looks like its going to work...its taking a rather long time, but it appears to be grabbing everything I was expecting it to.

I have a Nexus 7 2012 wifi. With the latest version of Lollipop it has really become unusable, freezing for a minute or more, or even rebooting while loading a page in Chrome.  I did a system reset, but that did not change much past the few first minutes.   What is the recommended version to have again a usable tablet? Is anyone having a "runbook for dummies" to install Android 4.x (or CM or whatever works fine) ?   Most of the tutorials I found on the Internet are for geeks wishing to experiment. I just want a running system with minimal fuss/risk.

I just broke the screen of my (unrooted) Galaxy S.  How do I get back my SMS and contacts?   PS: I tried Kies but it won't detect my phone for some reason. (Kies works fine with another Galaxy I possess but not this one)

I rooted my Dream/G1 last night and finally gave up on modding it (not for good mind you, but for the moment) and opted instead to just restore it to factory settings via Settings &gt; SD card &amp; phone storage &gt; Factory data reset, which did solve all the problems I was having with multitasking (and not being able to answer it, etc.)  Curiously, I still seem to have root on the phone, despite having reset it. I'd love to understand how that is possible! Superuser Permissions is the only non-stock app still on the phone, and I'm still able to use su to gain root privileges from adb shell. Is this because BusyBox installs to my SD Card?  My phone works just fine, so this is hardly critical, but the whole exercise was/is about knowing my phone better and this is most def. a mystery. Thanks!

I have an app installed on my phone, which I've installed from the Google Play Store.  If I update the app and don't like the upgraded version, is there a way to undo the update and downgrade back to the version of the app that I had previously installed?  I tried searching a bunch on this site, and I found lots of questions about downgrading the OS/ROM/firmware, but nothing about downgrading app versions or reverting an app update.

Does anyone know if there's a way to get an Android phone to reboot into recovery mode, from the Android command line?  Note:  I do NOT have adb access.  I do NOT know the magic power-on sequence to do it from the boot loader. I've tried the common things and nothing works.  I DO have root. (And can enter commands directly on the device using a terminal emulator.)  I know it's possible, somehow, because applications like ROM Manager do it. But how?

I upgraded my Nexus 4 to Lollipop a few days ago but I don't like it. I'll leave out my reasons because they're not relevant here. I wiped my phone and installed a clean stock 4.2.2 version instead. I'm happy with this.  Not long after, Android automatically downloaded the 4.3 upgrade and notifies me with the choices "Later" and "Install". I don't want to do this upgrade.  How do I:   get rid of the notification, and  remove the downloaded update (to free up precious storage space).     I have already tried choosing "Later" but the same notification immediately reappears.    Based on Google search results, I also tried going to Settings &gt; Apps &gt; All &gt; Google Services Framework and unticked "show notifications" but it still appears. Force stop or disable also doesn't seem to help, so I've re-enabled the service including notifications. I didn't see any other apps in this list that sounded relevant - did I just not see it?

I let my younger cousins play on my S4 from time to time, but now I have found that all the words they have used are the first to come up when I use my phone to text. It has gotten quite irritating. Samsung seems to have very hard to find settings compared to my old Sony Ericsson so I cannot find where to get rid of the word history typed onto my phone's keyboard.
