Wifi bricked after wrong backup restore - Galaxy A3, A5, A7, A8, A9 Q&A, Help & Troubleshoot

Hello everyone,
i just bricked my wifi connection with an old backup from a sony z1c.
i restored a backup named 'wlan access points' , since then i can't enable wifi connection anymore.
I thought if i restore a backup file from another samsung a3 i might be able to fix this.
so im asking you guys to upload me a titanium backup file of your Wlan access points so i can try it.
i guess a backup file from any a3 / a5 / a7 could do
Thank you guys and Best greetings from Berlin

i forgot to mention im on Lollipop 5.0.2
modelnr. sm afu300

[Q] i9000 data backup retrieval

Hi guys, i bought an i9000 and made regular backups of pictures videos etc, my phone was recently stolen, so I was wondering is there a way to extract the data from the backup files and where are the backup files stored on my machine, I used kies to create the backups.,
Any help would be appreciated
Just to add on, under preferences > device I can see the two backups I made their .sbu files so does anyone know how to get them and extract the data? would be a life saver if this can be done

Extract app+data from Nadroid backup and move to different phone?

Hello
Recently my galaxy S5 got stolen and I lost all my titanium backups on the SD-card and therefor my authentication app also got lost. Unfortunately I didn't save any titanium backups outside of the phone so now I can't restore the authentication app to my new phone.
However I found a Nadroid backup on my PC but the new phone is an old Galaxy Trend where I can't really find any recovery or any real support here on XDA on how I could fix it. Despite this I found an app that could root the phone so now I got root which could help me restore the authentication app if i find a way to recover it.
Kind regards!

EFS Partition deleted - still have IMEI but no wifi

Hey there,
I accidentely deleted my EFS Partition with no Backup. My IMEI is still there and I can make calls and use mobile internet. But no wifi/bluetooth/camera and flashlight.
Is there a way to recover without a backup?
I also have an old S5 which is not in use but for which I ve got an EFS Backup. Can I somehow use it? (with EFS Pro)
A lot of thanks
If it's the same make and model the efs might work. Try flashing it.
if you need backup tell me

Need to transfer apps and data from S5 to S8

Hi,
I got a new S8 yesterday and I am unable to use smart switch to transfer my apps and data to S8 from S5. I have CRdroid custom ROM on my S5 and I installed the Smart Switch app on S5 from google play store.
When i start the app on my S5, I get some error saying the "signining key is mismatched between the app and the firmware. Please check and reinstall ENG_APk to ENG_Firmaware or USER_APK to USER_Firmaware. Smart switch does not work if signining key is mismatched"
I would like to know if any of you have a solution to resolve this issue or any other method of transferring the apps and data from S5 to S8.
Thanks in Advance.
Regards
Sada
Make sure both phones are rooted
Install Titanium Backup on your S5 and backup all your user apps with data
Once finished go to your internal storage in your s5 and copy the folder TitaniumBackup to internal storage of your s8 and install Titanium Backup on the S8 and restore your data
Done

CRDroid is a custom rom based off lineageOS/AOSP. Smart switch only works on samsung (based) roms. That's why you get the key error.

For the same reason as above 99% of the time this will not work. You can't simply "copy" on AOSP and "paste" on Samsung roms. And even IF it works most likely there will pop up errors here and there.
My advise: Start with a clean slate.
All,
Thanks a lot for your responses and suggestions. I got my answer.
Regards
Sada
