[Completed] Android KitKat 4.4.2 removed SIM Management System File ! - XDA Assist

I was playing with my rooted device (BLU Studio X8 HD) and I uninstalled some "bloatware" system files that the program adviced to remove, and now I have no network only WiFi, and SIM Management is grayed out, it's disabled.
What can I do to fix this ? I do not have any backups of the system files at all

Greetings and welcome to assist. I can not find any firmware for your device on xda, if you do not have a back up of your operating system you will have to contact the manufacturer to see if they can supply one
Good Luck

[Completed] help me fix my xperia c

hello!
m in a deep **** trouble, a few months ago i rooted my xperia c so that i can flash the lollipop ROM. I wanted this this new ROM coz of the stock JB ROM looked crap n was laggy though there was nothing much heavy apps installed on it.
to the point,
before i actually flash this rom i had to flash the ftf file so as to change my s1 boot, but ya i messed around with my fone previously after rooting it, had installed a app called 'ULTIMATE BACKUP' so the i could convert some system apps to user so that i could have control over it!!
unfortunately i converted the 'SYSTEM UI' 'MTP EXTENTION SERVICES' 'KEYBOARD' 'PLAYSTORE' 'DRM MANAGER' and some other few like facebook n twitter albums walkman....
when ever i restarted my phone it would show me SYSTEM UI stopped working, so to over come this i installed a thirdparty launcher to use this phone but i solved this problem by finding another new SYSTEM UI.APK n placed it in the system folder of the device.
so i it would be greatful if anyone having a xperia c could juz upload "USB CONNECTIVITY.APK" "MTP EXTENSION SERVICES.APK" "DRM MANAGER"
so that i could atleast flash a stock android on my phone!!
thanks!

Hello,
I would recommend you to post your query here [GENERAL HELP] Post Your Questions Here Instead of Making a New Thread, the users running the same firmware as yours might be able to assist you.
Also if you wish to restore back to stock completely you may visit here [HOW TO] Update/Install/Restore Stock Android System on any Xperia Device .

[Completed] Can’t install any downloaded APK file on Android 5.1

Hi, I have the Homtom HT3 running Android 5.1 Lollipop with firmware version HT3 v2.06 and it is not rooted.
I have tried to install application from the Google Play store, some will install, such as Whatsapp, while others like Asphalt Nitro/8, Traffic Rider will not install (but it will download and there is enough space in my internal storage) (ERROR 505).
So I downloaded the game from the Muzhiwan market and when installing, the 'Install' button does not work. Hence, I tried to switch off App permissions, then the install button worked BUT the app was not installed. Note that Unknown sources .... is switched on.
I've googled and they say to disable Lux screen brightness something like, to my knowledge I do not have such application in my phone, it is a new phone out of the box.
Any help?

Find the stock firmware then flash the device with PC and your devices compatible flashing tool.
I DO NOT PROVIDE HELP IN PM, KEEP IT IN THE THREADS WHERE EVERYONE CAN SHARE
I'm not getting stock firmware in huawei website.
Tuusually I can free space on the internal memory of the phone in this way: settings - memory - internal archive - cached data (translation from Italian, excuse me). with my current phone, Huawei CUN-L21 Android 5.1 EMUI 3.1 I can not do it. nothing happens with a tap. another problem is that I can not move apps on the sd card. the option is there, but it is disabled (lighter color). what is the real problem of my phone?

Rootkit on an android? Now that's rare. If you tried every conventional method, I doubt anything is going to work. You can try disconnecting from the internet, check your running processes and services, kill them if found, scan with Malwarebytes and attempt to locate problematic files manually using explorer. There have to be some specific apps that are being installed, can you name them?
And full factory reset did not help you?

[Android System][Device Locked] Device Management has restricted certain features

I was installed some s8 random apps (downloaded from appmirror) by the following tricks from this forum.

1. Add a shortcut of the apk to the home screen from the my files app
2.Power off the phone.
3. Cleared the cache partition.
4. Restarted the phone.
5. Quickly installed the Apk by accessing the shortcut from home screen.
(Now it's installed )
6. But the launcher keeps force stopping.
So I cleared touchwiz home's data and cache from app manager.
7. Now it's working fine.
I also installed Bixby app through the same process.
Hope this solution works for all those who face the conflicting signature problem.

For some reason i was reset(hard) my phone (by wiping data + cash partition). After successfully reset when device is turned on i found an unexpected error like below:
Device Locked
Device Management has restricted certain features on your device.
Please contact the administrator to re-install Device Management to recover your restriction.
Now I can't access CAMERA(security policy restricted camera), SD-Card not found(showing not inserted), Bluetooth is also disabled. USB-debug is also disabled although DEVELOPER OPTIONS is enabled. Screen-shoot is also disabled. I have flashed my mobile multiple times after that occurrence with proper updated files(AP,BL,CP,CSC,pit). But my problem is still remain. I really don't know what to do. Plz help me out. Thanks in advanced.
N.B: I have also used a fresh gmail account but problem still remain. I have a backup EFS folder but i can't root my phone as usb-debug is disabled. I was tried multiple times to root my phone by CF-Auto root for sm-g930k but it stuck on KT logo and as a result i have flashed it again and again. :crying:
Sorry for my bad english.
Sent from my SM-G930K
