[Q] Undelete sys app - Android Q&A, Help & Troubleshooting

Hi
I accidentally deleted a system app from the recycler of the app 'root app delete'
Now when I boot the phone it has a flashing screen. ( home screen ) but can't gain access
I have tried system reboot
I can gain access to system tools by swiping down, but I can't access any tools or app.
I have tried the application root app undelete by bluetoothing the apk file from my other phone and can install and run from the file download but there are no recoveries.
I don't know which one it was unfortunately.
Is there anything I could do.
It's a chinese clone S3-i9300 and have looked at flashing a rom but I have no idea which rom it needs
Thanks
Lee

[Q] removed app advisor, still there

hi there.
i have a problem, i removed LG App Advisor from my rooted OO, but the program is still in the menu and it is still working (like nothing happened),
i used the terminal emulator proceedure remounting the file system and then removing the program, this proceedure succeded with every other program, but seems useless against AppAdvisor...and i don't know why, but since i'm a newbie could be my fault...what should i do to remove permanently the app?
Try TitaniumBackup and restart phone after procedure.
Go to Market, download Root Explorer, launch it click on top on mount r/w then go to /system/app and remove App Advisor (I don't remember the exact name, but it has to contain app advisor .apk) from there.

Deleted my only Launcher and APK - Black Screen. Please help!!!

Hello everyone,
I have a Lenono A806. The device was rooted and I downloaded an root uninstaller from the Play store to uninstall some apps that I couldn't otherwise.
In the process, among other apps, I deleted the only launcher I had on the phone (Lenovo Launcher) and I might have deleted the APK (not sure about the APK). The result was a black screen without any apps.
When turn on the phone I can see the home screen (same one you see before you unlock keyboard) and I also have some of the functionalities (eg messages, can make calls etc). However if I open one of these functionalities and I click on the "back" button, the screen goes completely black and the phone goes unresponsive. I tried to reset factory settings by holding the Volume Up + Down + On/Off button which opened the "Lenovo Recovery" screen and I choosing the "wipe user data (both fuse format and fuse wipe data). I also tried he install update package option and I rebooted the phone. Nothing of those worked.
Could anyone direct me towards the right way?
Thanks in advance,
Ilias
Sideload a 3rd party launcher via adb.
Try install any launcher using pc or using recovery.

if ...
you can access your file manager then I would suggest obtaining a launcher apk, putting it on your sdcad and then installing it from there via file manager. I like ADW very much - it can be had from here:

Unable to access root

I rooted my Micromax A104 KitKat 4.4 with Kingroot and after using for some months I factory reset the phone without removing the root, (without unrooting) now I tried rooting again with the same method as before but I'm unable to gain access to root.When I tried to install the app. It says there is a same application with a conflicting certificate. (Problem is I don't find the kingroot or superuser apps in the apps drawer,and there is nothing to be found even in the list of install apps.) Now, even when I access /system/apps/ folder there is no install apps found in folder.
Note: When I install superuser apps it says su binary needs to be updated and when I tried to update, it fails.
That's because the SU app and binary are not in the normal app places. Basically you will have to either track down where it installs and remove it (will need Root for that) or flash the stock firmware.
Thanks...for the info.

Kingroot stuck as system apps

I rooted my phone using kingroot before and after removing al root authorization i found that kingroot has been installed as system app
also whenever i open the kingroot app it restarts my phone
how could i completely remove it
there's also the problem of the phone not able to connect to google play store (no connection, cannot login account)
my phone is NTT Docomo Sony Xperia SO-O4E
tried factory reset twice, deleting cached apps data, still doesnt work
a basic rundown on how it all happened :
-uninstall some bloatware from phone
-phone starts to restart randomly
-deleted cached apps data, no more random restart
-remove kingroot root auth and uninstall
-found out that phone cannot connect to play store, also kingroot has installed itself as system app

If your bootloader is already unlocked, the easiest way would be to restart the phone in fastboot mode, then boot (you don't need to flash it) TWRP and install SuperSU from a flashrecovery zipfile. This will remove kingroot app and running processes (mind you, there may be some dead kingroot traces left over on the filesystem - if you want to remove these too, you'll have to do so from a shell with root permissions). I haven't tried this with the Sony Xperia ZR/NTT Docomo Sony Xperia A (SO-04E), but it seems to work with most phones that are supported by TWRP. I wrote a short guide on how to do this (it's for a different device but these steps should be mostly generic if you have the necessary prerequisites in place).
Another good thing about SuperSU is that if you don't wish to keep root, it will remove itself cleanly and completely from your system (you'll find the unroot option in the apps settings). If however you would like to keep root, then SuperSU is an app that doesn't spy on you and doesn't phone home (I did a thorough check of the shell script used to install SuperSU and a rough check of the SuperSU apk using strings and wireshark only yesterday and as far as I could tell, it doesn't attempt to do anything malicious or touch files that it doesn't need to touch for its purpose, nor did it start a single internet connection by itself). The automatic NVISO analysis at https://apkscan.nviso.be/report/show/99a7841aa3eeaefa69f767602b0c454c confirms this too. Just saying this in case you decided to move away from root due to spyware concerns.
TWRP is an open source project. Their Homepage is https://twrp.me/
The TWRP image files for your device arel located here https://dl.twrp.me/dogo/
SuperSU homepage is https://www.chainfire.eu/ , the latest flashrecovery zipfile can be found here http://www.supersu.com/download
Both projects also have their own sections here on xda.
SuperSU also has it's own sections here on xda.
there's also the problem of the phone not able to connect to google play store (no connection, cannot login account)

Was this problem related to the rooting process in any way?
Does your internet access work otherwise?
What happens exactly when you start google play?
hi, thank you for the reply
the phone has only been rooted once with kingroot app, which i have removed (both the supposed app and the root auth), but kingroot app installed itself as system app without my permission and whenever i open the app my phone reboots
i'll try looking for ways to flash the phone
as for the play store, it always show the no connection screen even though i can browse the internet without any problem
i tried following the steps from google help page but it doesnt seem to do anything
i'm thinking that the hosts.txt file cause this so im trying to delete it, but i found no other way to delete it without rerooting my phone
i tried factory reset twice but it doesnt seem to help either
thanks before and sorry for the late reply
EDIT : i dont think i can unlock the bootloader officially so i need an exploit

In that case, you will have to root first. Once having gained root access you can unlock the bootloader. To root, you can either use the kingroot app you used before (not much to loose, since you already installed it and its spyware the first time, and you will later be able to remove it with SuperSU). Or you can try towelroot, although if your smartphone has seen firmware updates, that will propably no longer work. There may be other, more current options - search trough the Xperia ZR Section.
Once you have root, you can use adb and fastboot to boot the latest TWRP for Sony Xperia ZR, then install the latest SuperSU recovery flashable zip. Using that you can completely remove Kingroot even as a system app and afterwards remove SuperSU itself, which will cleanly uninstall itself via Settings.
Code:

I would try the above first, see if the playstore works again after you SuperSU has completely removed Kingroot (reboot), and if it doesn't take a look at the hosts file. Then uninstall SuperSU when you don't need root anymore...
I can help along with adb/fastboot commands, but you need to root your device first (and install the necessary drivers for your phone on your computer).
Good luck!

Trouble with Kingo Superuser on Lenovo K910l. Please help!

I tried to root my Lenovo K910l using Kingo Root (yes I am a noob). The app could not root the phone but it ended up installing an app 'superuser'. Now this app won't uninstall. When I open this app it shows the phone is "not rooted" and asks me to "root" now. When I tap the link, it asks me to download Kingo Root app which again fails to root the phone. This app has taken over the control of the phone and I want to remove it, but no success. I have tried to factory reset and even formatted the phone but to no avail. The phone isn't even booting up in normal recovery which I suspect is due to this superuser app. I am thoroughly confused. Any help would be greatly appreciated.
try these
1. trying to root any other app and get the root permission for rom tool box lite. (install this app from play store). now open this app and you can easily uninstall any app.
2. thats not work? search with malware using any antivirus app. this superuser is the one of the type malware. then you can find and erase with the app
3. full format with sd card and internal memory or install new update frimware using official site :good:
Thanks for the suggestions, but I tried to root it again with the PC app, and then tried to uninstall it later. That somehow worked. But unfortunately I ended up with my phone unrooted again and in the process my phone is still not booting up in recovery mode and I can no longer see it or access it through my PC.
