[SOLVED] WiFi won't turn on after nandroid restore - Nexus 7 Q&A, Help & Troubleshooting

Wanted to restore a backup, so I wiped my Cache, Dalvik Cache and System then restored a TWRP nandroid backup. After booting back into Android I can't get any WiFi whatsoever.
In Settings, I clicked the Off/On button on WiFi, it changes to On but it doesn't show a Wifi icon in Notifications area. So I clicked WiFi and it just shows a "Turning on WiFi..." message on the next screen.
I've also tried enabling disabling Airplane mode, but makes no difference. Bluetooth works though. Even WiFi Analyser tries to turn on WiFi with no success.
Any ideas what's wrong?
Using Stock ROM, unlocked and rooted.
edit: Opened a terminal emulator and ran logcat, shows this which is probably relevant? W/IInputConnectionWapper( 5025): showStatusIcon on inactive InputConnection

Couldn't figure out how to fix it so I restored an old CWM backup I made when I got the device, WiFi worked, so then I restored the TWRP backup again, without doing the manual wiping beforehand (that must have affected it somehow?), now WiFi works.
Odd.

[Q] System UID Inconsistent Error after Titanium Backup

I searched and haven't found anything that's worked.
My phone was running fine after I flashed the crDroid rom. I then used Titanium Backup to only restore Bluetooth Connections, to see if it'd work. I had tried this same thing before with a full restore, and kept getting stuck in a Boot Loop, and had to restore and wipe constantly.
Now after I rebooted, it's giving me the "System UID Inconsistent - Please Wipe Data Partition .... I'm Feeling Lucky"
I press the I'm Feeling Lucky, and a lot of apps are gone. Is there a fix for this other than restoring and reformatting again? I've downloaded the Fix Permissions app from the App store, but no luck.
Thanks for any help!

I think you have not changed the settings in TB to the "legacy" folder. Search the forum for solutions
Probably the cleanest solution HERE

[Q] Wiped data, flashed rom, restored data and phone not turns on, keeps restart

Phone is huawei u8800. aurorasp was in it.
I had a problem. It was restarting before turning on. I tried a lot of things but could not manage to solve. SO i wiped data from cwm and installed aurorasp+ and restored backup. Again it went into restart mode. I made advanced restore and restoreonly data, but again same restartinng trouble.
Before restoring data, the phone is working, no restarting.
I want to take this data. How can i take data, for example contacts, app datas?
WAiting help.
I solved. I used titaninum backup pro and installedf most app+data but forexample my desktop app icons, my settings for brightness , etc was not restored but it is good.

[Q] Problem restoring backup

I tried a new rom (http://forum.xda-developers.com/gal...galaxy-s5-stock-rom-final-fast-clean-t2888215) for the first time and it wouldn't work properly (no mobile connection, menu and back buttons didn't work, etc.)
When I restored my backup, I did it like I always did on my last phone: wipe data/cache/davlik cache, restore backup, reboot.
I can't get past multiple notifications that process.google.gapps (might not be exactly what it said) has stopped, and I can't do anything but pull my battery and try another ROM.

Titanium Backup restore of XML data causing boot loops in TW Lollipop, need SMS data

I just updated my S5 to the OTA Lollipop, then installed XtreStoLite Lollipop version. I had a TiB backup of all my stuff from KitKat.
After a TiB restore, the phone worked fine until I rebooted, then it went into a boot loop. It would load the OS, and I'd have maybe 8 seconds before it rebooted on it's own.
I did a factory reset and tried again again, this time I did everything very slowly, rebooting very often to figure out what it was. I had made many more changes than just hte TiB restore, so it took a while to find out that was it, and the particular item that was restored.
The culprit was the Wifi Access Point XML backup (shows as a yellow listed item). When it was restored, and the phone rebooted it started the boot loop. There isn't an option on TW to clear all saved wifi data, nor the time. To fix it I had to ADB shell while loaded into CWM recovery. I did an
echo "" > /data/misc/wifi/wpa_supplicant.conf
Click to expand...

and that seemed to fix it. I didn't mind losing that stuff.
Problem is after restoring the TiB SMS backup XML data, it seems to be going into the same loop. After the restore I was able to open the SMS app and view all the imported SMS messages just fine. It appears the import worked. But upon the next reboot, it started the boot loop again. I could probably remove /data/data/com.android.providers.telephony/databases/mmssms.db, but I do actually need them.
Does anyone know why this might happen or how to solve it?
Well, deleting the mmssms.db didn't stop the reboots. The file was 600k, but the TiB backup is 50mb, probably due to images. Don't know where that's stored.
EDIT:
Actually, just realized the rebooting is because the wpa_supplicant.conf was recreated after adding wifi. So something in the TiB wifi restore killed something else. Seems removing wpa_supplicant.conf is only a temporary fix and I can't use wifi or it will recreate it and continue the rebooting :/

BT doesn't turn on

Hi,
I have a rather strange problem: since this morning, BT refuses to turn on. I've alreaddy reflashed the latest software version (N910FXXS1COK2_N910FOXA1COJ3_DBT), cleared cache and dalvik-cache, deleted cache and data of the bluetooth app and even deactivated all XPosed Modules, but nothing helped. I've recorded a catlog, maybe someone here can see what is preventing it to turn on. I don't really have any idea what could have been happened. I tried to make an backup with TitaniumBackup which seemd to have failed because I turned off the screen, because it had'nt backed up much about an hour later when I looked for it.
Ok, after wiping about everything in TWRP and reflashing firmware again, bluetooth is finally working. But does annyone know how this could be fixed the next time without wiping everything?
probably part of the bluetooth on the software side got screwed up.
