Wifi not working after root - Android Q&A, Help & Troubleshooting

I recently rooted my redmi note 4. After root I used the phone for some days without any issue. But, After updating of the application Device Emulator Pro I am facing wifi not found issue. Now I am unable to find any wifi which is nearby me.
I tried entering SSID and password also, but not working. So, is there anybody to help me out. I will be thankful to the expert. Thanks.

Inside description of the XPosed module Device Emulator Pro it's highly recommended to create a backup of device first before using it. Did you?

No. I didn't create a backup. This my mistake. But now is it possible to fix the issue without that backup file?

Restore network config

Hi,
exist a software that restore the network configuration as stock, i think that i have a corrupt file or script and my xt910 doesn't connect at 3g network...
how can i solve it?
THANKS!
There might be an easier way but during a recent browse of the moto customer care forum i read through a moderator thread about restoring connectivity settings. Issue dealt specifically with issues arising after installing Easy Battery Saver+Task Killer but the apk will probably work for you.

[Q] I destroyed my phone's wifi

Well I finally managed to destroy my Phones wifi....I was trying to get hack the phone with Terminal Emulator to modify the wpa_supplicant to get it to recognize ad hoc networks and booom.
I must admit I did not know what I was doing. For everything I have read elsewhere I beleive the only solution now is to install a new rom....
The problem is this is the first time I would do it.... I have read guides on other threads but I am not still very sure how to do it or even if it would solve it.
So when I turn the wifi on, besides having lost all of my stored wifi profiles, it doesnt scan, and turns off automatically. Sometimes I even get a wifi error.
I have an Xperia Ray, rooted, I restored to factory settings but that didnt help....I rolled back to a backup I had with titanium backup and everything came back the way it was except the wifi.....wifi hotspoting works by the way.
If someone would please be so gentle to tell me what way to go, that would be a charm; I am half decent with Androids, and above Standard with Windows...
Thanks!
AW: [Q] I destroyed my phone's wifi
You could try to restore the wpa file. Extract it from a stock or custom rom and push it to your device, it should restore the default settings. Maybe it's cached somewhere.

Have the same problem on my GNex. It's not root because Adaway can install the adblocker.
my root is working perfectly fine tho
temasek already explained. i'm guessing it's that sdcard permission thingy screwing things up
BUT, i've tried to backup to local and still showing error....weird
this is really scary, can't backup my data...
i did flash back the cm10.1 and it works fine again, guess just the app doesn't support cm10.2...

I've found a fix that may help you:
To fix, simply go to Settings->Developer options (if you don’t have that option go to About phone and hit Build number like 5 times until it says you are a developer), and set Root Access to “Apps and ADB”.
Then close all of your apps and re-open, you should now see Superuser window, problem fixed!

Unfortunately, because I've not enough posts, I can't link direct to the article but, I found it on the HighOnAndroid website.
Worked for getting Titanium Backup running on my S2.

It's not worked for me (S4 cm10.2 from cm10.1)...
This is worked for me:
Titanium backup Users
1. In tb go to menu>preferences>backup folder location
2. Navigate to storage/emulated/legacy
3. Select your Backup folder and Select "Use the current folder"
4. Then it will ask you to move backup to that folder.... Select that
5. Restart app and restore.

[SOLVED] HELP!!! Huawei Mate 10 Lite TelephonyProvider

I have accidentally deleted my TelephonyProvider app and now I can't unlock my SIM card!
I am in urgent need of TelephonyProvider app from a working Huawei Mate 10 Lite.
I couldn't find the stock ROM anywhere so I couldn't fix that by myself
I'm using RNE-L01 model Huawei Mate 10 Lite and RNE-L01C432B130(EMUI 5.1, Android 7.0) is the ROM the phone is running.
I'd really appreciate it if someone could help me and send me theirs...
If you want to copy and send me yours, I have to tell you that the full path is /system/priv-app/TelephonyProvider/ and it will require root to get it from there. (And yes I'm probably going to need the whole folder)
Thanks in advance!
UPDATE: Now phone can't detect my SIM card at all and in status, IMEI number stays unknown... I wonder how did that happen as I only touched that particular apk... plus supersu root and xposed(no modules as I started having problems before I could tend to that.)
UPDATE 2: As I've received and restored the TelephonyProvider apk I'd accidentally deleted, all those problems above are now gone! Thanks again @kilroystyx

You can try mine, not from same ROM (RNE-L21C432B120) but should work.
Thanks, I'll try that.
Edit: Seems like it didn't work. Thanks for those though.

Factory reset
I obviously tried that as well.... But since I've messed up my system partition, factory reset can't do much for me

How do you messed up system partition? Just be curious
I was restoring a backup apps etc from a Huawei G8 using Titanium backup. But when I restored them, dialer and messaging apps started crashing whenever I opened them. I had obviously restored my call log and sms messages the wrong way. To fix it without a reset, I tried deleting the data I backed up using the very same app and in the process I happened to delete the apk by accident(which is a system app itself).

Don't understand then why a factory reset could not fix this issue
Because it basically wipes data,cache and dalvik cache partitions. It does NOT touch system partition at all.

You could maybe ré install original Rom. Couldn't you?

I would've done that already if I could find it. However I can't seem to find it on the Internet as even search engines return very few results containing the build number of the ROM and none of them actually have the ROM. I could only find firmware with build RNE-AL00C00B155(Model RNE-AL00) when I searched for huawei mate 10 lite but the model doesn't match mine(RNE-L01).

Edit:
YESSSSSSSSSSSSSSS!
This one worked perfectly! My IMEI number shows up again and it can detect and unlock my SIM card!
You, sir have saved me from having to bring my phone to service(and possibly void my warranty - I also happened to somehow lose the unpatched boot.img, instead it always has SuperSU root in it and because of that, I couldn't even lock my bootloader back without making the phone unusable, though unlocking bootloader again solves that issue.) because of the SIM card function I broke within the very first day I bought this phone. I can't thank you enough for that, seriously. I believe the thank you button will not be enough for this but I'll do the only thing I can to express my thanks and click that anyways.

Was enough or do you need some more apk's to restore?

No, this is the only apk I had accidentally deleted, therefore the only one I needed to restore the functionality. Thank you once again, you're a lifesaver! At least when it comes to my phone's SIM detection, that is.

As I thought our models are sharing the same system.
I'm glad that you fix your device

So, in that case make a TWRP backup, to avoid this kind of issues in the future.
You're welcome

The problem with that is, I'm unable to back up the data partition with that. Somehow I'm getting a createTarFork() ended with ERROR:255 on that.
I was able to successfully backup my boot, vendor and system partitions though and all of this happened after the problem has started and before it was solved.

Because your data partition is encrypted.
Under my signature you can see what I did to manage this issue.
Root with decrypt option and then decrypt data.

Can't restore backup using smart switch

Hello all,
I recently tried to flash some new firmware on my Exynos Galaxy S9+, and before doing so I backed up my data on my PC using the Samsung Smart Switch desktop app. After doing so, I decided to revert back to the old firmware, and restore the backup I had saved. The problem is, whenever I hit the "restore" button on the Smart Switch desktop app, I simply get a message saying "Restoring the S9+ data has been cancelled." with the only option being "confirm". I have searched on google and nobody seems to be having the same issue. Is there a fix for this, because I really need to get my data back.
If it helps, I know exactly where the backup folder is located, it's just restoring from the backup that's giving me issues.
Thanks!

Did u find the solution am having the same issue on my s10 plus
YES! I got it after 3 hours of struggling. Now the process finally started. I hope no more obstacles will be on the way.
I had cleaned my S10 to factory settings and i had the same problem as you.
In my case i had to update Smart Switch on PC (not from app interface - it didnt work, but i had to download new version of app from samsung site).
I also did something before, I changed back the folder of backup on PC into default one (previoulsy i manually changed it). Maybe this helped too.
Good luck!
