unrooted lenovo tab 2 10-70 - unable to update OS - Android Q&A, Help & Troubleshooting

The 5.0.1 Android unrooted tablet was sent to a service lab, where it came back from having its motherboard replaced, when for some reason its OS was downgraded to Android 4.4.4. Since then some apps do not work, such as TV apps (that worked fine before) - the tab cannot play movies and shows on those apps, although those apps are supposed to work on Android 4.3 and so on. Moreover, since then I cannot update my OS, tab saying that I have the latest version (which is obviously not true) and when going to the Tool Kit saying that "An error has encountered when installing the recommended incremental update pack". Factory Data Reset did not do anything. According to the Root Checker, the device was not rooted, although it seems to me that the lab has messed with my OS. What do you think? The lab says though that my OS is "beyond their control" and that they could not have touched it, just replaced the motherboard with an original one, suggesting me "just to wait" for the update to come out, which I am sure will never happen. Any suggestions how to solve this? Do you think that the lab has messed with my OS or what do you think happened here? Thanks a lot, guys!

Can anyone answer that?

Can anyone answer that please?

Flash Android 5.1.1 LMY48M Lollipop Factory Image for Google Nexus 10

Google has issued a brand new Android 5.1.1 Factory Image file that should patch the StageFright Security bug forever. If you want to install a clean Lollipop OS on your tablet, then you should check all the info listed in this post.
The StageFright Security bug should’ve been fixed with the previous LMY48I Android 5.1.1 release, but that didn’t happen as tons of Nexus 10 users have reported that the security vulnerability was still there. If you want to be sure that this bug is fixed, then you should flash the latest LMY48M firmware version of Android 5.1.1 Lollipop OS on your tablet.
Installing a factory image on your will always remove all the data from your tablet and you should create backups before starting the flashing process. Read the following guidelines first:
use this post only with the Google Nexus 10 tablets.
– don’t try to update any other different tablets with the files that you will find in this post.
by installing this Android 5.1.1 LMY48M factory image you should know that the flashing process will remove all data from it.
– however, if your tablet is running a stock Android 5.1.1 LMY48I build that hasn’t been modified in any way, then you can use a small workaround in order to avoid the ‘factory reset’.
– more info on the update workaround can be found when you reach the tutorial instructions.
backup all the important files before starting the installation process.
enable USB Debugging for your tablet from its Developer Options menu.
– if you can’t find Developer Options under Settings menu, then you should enable it first: go to Settings> About Phone and tap 7 times on the Build Number section.
– return to Settings, scroll down, open Developer Options and find the USB Debugging option in order to enable it.
use this post only if you are an advanced user.
we cannot be blamed in case you end up losing any data in the process nor in case you brick your device.
check your Nexus 10 battery charge level and make sure that it is over 40%, it will prevent your device from powering down during installation.
read the whole tutorial and make sure that you won’t be skipping any steps, so that you will be able to complete the factory image installation at your first attempt.
I've used three different browsers to read this page in case I have some sort of content blocker active, and I see no tutorial in any of them...?
It's always nice to see people trying to help, and notifications of new ROMs are always welcome (though I installed LMY48M weeks ago), but there are already hundreds of tutorials showing how to upgrade a ROM - maybe you decided not to go ahead with the rest of your post?

I've had the same problem, plus now I have battery issues. The tablet won't fully charge and will randomly turn off after some unknown time of use.
This update has killed my battery.
Beware of this update!!!!!!!!!!!!!!!!!!!!!!!!!!!! IT TOTALLY SCREWS YOUR NEXUS 10!!!!!!!!!!!!!! I´m reverting back to LMY47V because the newer updates are bricking my Nexus 10! I have flashed and reinstalled it 10 times by now, it just can´t handle this update! I think they did it for you to buy a new Nexus device by killing the Nexus 10!

Are you referring to build lmy48m or lmy48t?
I can't get to flash anything. Even after flashing another version, the old version just stays. I've tried everything. Formatting, erasing, downgrading, nothing works. I think my Nexus 10 is officially dead. It will boot up and like 1 minute after it just crashes and reboots again. I have read that others have this problem, could be that the motherboard is shot. Since there are no motherboards available, I can't even repair it. It lasted exactly 2 years, what a waste!
Well I just spent hours going through all the ota update from original jelly bean that it came with up to the latest lollipop build lmy48t and everything is working fine thus far.

Help! Modified Android on New Handset?

Hi, thought I'd come here as it seems to be full of Android experts!
I bought a Samsung Galaxy Mini S4 - GT-I9195I from eBay.
The phone was brand new, but not sealed and the phone had already been through the initial setup process, although all the new stickers were all over it.
However, when I try to update the handset, I get this message -
The operating system on your device has been modified in an unauthorised way. Try downloading software updates using Samsung Kies on your PC
Could this be down to apps that are installed? (Whatsapp, a Countdown game)? I have tried to use the Samsung software but get told after the latest update has downloaded that there was an error verifying it?
I'm really not sure if the phone has been hacked or not. Could this message be because the seller unlocked the handset? When I view the status of the phone in settings, everything looks normal although shaded out. It's on Android 4.4.4. Build no. KTU84P.I9195IXXU1AOD1
Hope someone can help.
Thanks

Kingzone

Hey people,
I have a big problem and I am a big noob what contains to software, hardware is my thing.
Lets get straight to the point......
I have rooted my device(Kingzone K2) with Kingroot on Android lolipop 5.1.
the first time i tried to root it would not work because my phone had a unknown version of android or something like that, so i reported that to kingroot and a month later they made it possible to root on my device.
now I have rooted my device but I started up my phone and all of a sudden my phone was reset to factory setting.
I thought it would have been a accident with android devicemanager.
And up following I wanted to download apps and stuff but it gave me the error that Android.procces.media was stopped.
And the apps wont download I tried everything to download them, also camera and gallery wont work for the same reason.
So can someone please help me with this problem.......
Thanks.

Lenovo Lemon 3 - irritating problems with stock ROM

Hi!
I'm new on XDA, so I'm sorry if the thread is placed in wrong subforum - if it is, I'm asking mod to move it in more proper place.
I bought Lenovo Lemon 3 - it was advertised as Vibe K5 Plus, but apparently the seller wasn't that reliable as I thought. As far as I know, the differences beetwen these models are little or none, but I have pretty big problems with the phone.
First of all it has some preinstalled software, which isn't in Play Store and some of them I can't even find in the net. The apps I would like to get rid off are KingRoot, MaxxAudio and SecurityIT. I successfully managed to disable MiBrowser - with help of KingRoot tool Purify actually. I tried to disable SecurityIT also, but if I do that I can't enter Settings->Apps. When I try the com.android.settings is stopped and it's not working till i enable SecurityIT again.
Second of all is that process com.android.phone is stopping randomly. Sometimes I click "ok" and I it starts working again. But sometimes it keeps crashing until I restart the phone. Since it's a dual sim phone and I'm using only one sim I thought that maybe this is causing a problem, but inserting second card wouldn't work, so currently I have no idea what is causing the problem. I tried cleaning cache and appdata with no effect. If the process is crashing and somebody will call - the phone restarts itself when I try to answer.
Thirdly it's hot. Even if I'm not doing anything and all apps are off and Im charging the phone it sometimes says that it can't be charged because of too high temperature on battery. Sometimes it works fine, but sometimes it's too hot too touch and I don't know why.
Oh, and one more thing. Something is installing random software. It looks like every time I open Chrome something is opening new tab and redirecting to PlayStore. I am trying to close these tabs while they're loading, but sometimes it loads too fast. Every morning I uninstall some new app, which is apparently installed by night. And those apps aren't added to my Play Store Account. I have disabled unknown sources, but I can see that phone is checking for updates around 2 a.m - so maybe those apps are from there - but I can't see any possibility to disable auto-updates. I have disabled auto updates in Play Store and I have "Lenovo Enhanced Experience" unchecked. Most of apps I installed from Play Store are games I had on the previous phone so I am sure they're not dangerous. Any ideas to prevent the installation of this unwanted software will be appreciated.
Since I used KingRoot to disable MiBrowser I apparently rooted it, but I was reading that this works only with KingRoot installed and with internet connection. And it's sending some data to China, which is not nice. RootChecker says it's rooted.
Lenovo Launcher it's not great either, I downloaded Lollipop Launcher from store and it works fine, but I had to block Lenovo Launcher from autostart, because it was very irritating and was enabling few times.
I am living in Europe so I was thinking is it possible to put on this phone Lenovo Vibe K5 Plus Stock ROM? Or is it this "trashy" like the one I have? I really like specs of the phone and I don't wanna return it, but I don't like the software behavior. Can you tell me what I can do to improve this? I don't care about warranty and I would like to have pure, non trashy Lollipop, so if it is possible somehow I would be glad for any help.
Thank you in advance for any help!
Lenovo Lemon 3 K32C36 > Cyanogenmod 14 - 7.1.1: SUCCESS
Hi
Did not know where to post this, I was not allowed to post in developer forums:
For those unlucky enough to have bought a Lenovo Lemon 3, I offer hope. My daugther's 'Lemon' now runs cyanogenmod 14 near flawlessly.
Here's what finally did it.
1st you have to unlock the bootloader. I found this page, google translated it,
http://4pda.ru/forum/lofiversion/index.php?t717648-420.html
and near the bottom is this link to a 'one-click bootloader unlocker'
http://lenovo-forums.ru/applications/core/interface/file/attachment.php?id=56376
[All this is similar to the Lenovo unbricking described here:
https://forum.xda-developers.com/k5-plus/how-to/unbrick-vibe-k5-plus-qfil-qpst-method-t3467830
but a lot of that is not what you need now.]
You have to install and run QPST from this on a Windows machine, and the Lenovo and Qualcomm USB drivers and the Visual C thing too to set it up.
I fiddled for a while but eventually got QFIL to recognize the Lemon. Keep in mind Win is pickier about USB cables than Linux.
Following instructions carefully, that one click then worked!
I moved back to Linux and adb and did the second part (pasting instructions from the Win .bat file into a root terminal). Sure enough, when I booted into recovery I had TWRP! But it showed no files on the Lemon and said there was no OS there! Nevertheless I was able to boot back into the awful K32C36 system with no problem.
So I went back to adb and did it again, but this time from the info and links on this page - but I did not at that time see the need to root.
https://forum.xda-developers.com/k5-plus/development/recovery-twrp-3-0-2-0-lenovo-vibe-k5-t3391100
Beyond all expectation TWRP then booted and all was visible.
I then picked this ROM page because someone had wrote that they had it working on K32C36
https://forum.xda-developers.com/k5-plus/development/unofficial-cm14-lenovo-k5-k5-plus-t3478288
to get this
http://moto.shreps.fr/Lenovo Vibe K...cm-14.x/cm-14.1-20161213-UNOFFICIAL-A6020.zip
Then onto SD card with it and pico 7.1.1 gapps
Install with TWRP (after backing up lame old ROM and wiping system, data, cache, as advised).
Long wait during 1st new system boot (I thought it was defeat) -- but comes the little blue man bringing very good Nougat.
Hope someone gets helped here .

LG G4 Unfortunately com.android.settings stopped working

i have LG G4 h810 5.1 official then after i update it to marshmallow using auto updates and when i clicked on security option in settings then i get error "Unfortunately com.android.settings stopped working" i try factory reset many times but nothing happens i think that the latest update which i applied to my phone has an error inside it.
can someone help me ?
same issue here man, i had been browsing all over internet trying a lot of solutions, none of them worked i tried to root the phone, install a new firmware, i cant find the right firmware for it. is there somebody who can help us?
I'm stuck with the same issue... How to fix it...
Have you guys tried other firmware such as Lineage os or cyanogenmod?
I'm stuck with same issue... Can't install apps from unveriffied source.
I also have been on this issue of setting app crashing when I try enter "Apps" in settings and click on any app, for weeks trying to fix it, including factory reset 10 times, clearing cash and starting new account on my phone, after I noticed it on my seldom used LG G4. But now it looks like I finally fixed it a minute ago (my com.android.settings stopped crashing, at least for now.) I used free App Manager by AndroidDeveloperLB from Google Play Store. It has option... something like uninstalling updates (or rolling a selected app back to the original installation). I uninstalled the update, and app "Settings" stopped crashing. Now I am waiting to see if system will install this update again, and if it causes crashing again... then I will think what to do... If crashes again, then I guess I will have to do a research and block updates for this app somehow)
Am stuck with same problem too. Cant install apps or set a lock code for my LG G4 H810 from ATT running on Marshmallow
i have LG G4 h810 5.1 official then after i update it to marshmallow using auto updates and when i clicked on security option in settings then i get error "Unfortunately com.android.settings stopped working" i try factory reset many times but nothing happens i think that the latest update which i applied to my phone has an error inside it.

I just fixed this issue on mine, only thing I did was restore my system through twrp. I made backups of prettymuch everything while the phone was experiencing bootloop because I guess I stopped google play services with airfrozen. Seems to have that effect anyway... So before factory resetting, decided to do a backup of system and data and prettymuch all the essential things, then reset and got the problem popping up in a fresh reset phone. Strange that my original more hacked and unlocked rom seemed not to have it... I couldn't enable debugging so I had to resort to twrp to figure out what to do and took a gamble and restored the system. Wow, so shocked when it showed up normal again.
So only take away is that the problem is isolated in the system part not data. If it is something to do with google play store and maybe I rolled things back to a previous version, I have no clue. Wish I could say for sure. If you don't have twrp, get it and you'll be back up in no time in some form I'm sure..
