[Q] Nexus 4 Device Administration

I am on 4.2.2 and my security settings no longer works on my unlocked and rooted Nexus 4. It crashes each time I try to access.
It may have started after I installed my Gotcha Facetrap app. I can access part of the security tab (passwords only) through the facetrap app but can not get to the rest of the security items.
I have tried to uninstall the app and reboot but to no avail.
All I really want to do is enable the install from unknown locations.
Anybody have some ideas how to fix? Maybe through adb? I hate to wipe and reinstall everything.
Looking forward to suggestions and ideas.
Update
I found that compared to my Nexus 7, which is working fine, the Nexus 4 has all the Device Administration area greyed out when I access it through the Gotcha app. Any idea how to get Device Administration rights back?

I dont know how to bring the Security settings back except flash a rom :|
Just wait a little more and someone may help you.
But if you have to flash a ROM and dont want to reinstall everything, why dont you try Titanium backup? Then copy your apps' data to your computer (such as games because gaames' data is heavy).

[Q] Tethering + Mac Address Spoofing?

Hi! I've got a Nexus 4 running CM 10.2 / Android 4.3 and I've been trying to spoof the Mac Address it sets when tethering, to no success.
The reason I'm trying to do this is that the Nintendo 3DS now uses this nifty new "Street Pass Relay" feature which checks the Access Point Mac Address to exchange high scores and other data with strangers around your zone, but with this, we can get data from strangers around the world.
The Native tethering app generates a random Mac Address every time I start it, and I've tried several options (including busybox ifconfig hw ether wlan0 xx:yy:zz:11:22:33 ) but none of the options have worked so far.
Has anyone done this before? Via an app or a script, I don't mind.
Thanks.
Wireless Tether for Root Users has MAC address spoofing as a feature as of 3.3 pre2. That version is not in the play store yet but the APK can be downloaded from the project page (Google it, I can't link to things. Or go to the #DS subreddit and find the thread about it there someone links to it in the comments). I tried getting it to work earlier but turns out the app won't work at all with a Galaxy Nexus. Others have had luck with it though.

I tried both versions of that app, 3.3beta 2 and 3.4 experimental to no success in my Nexus 4 , Schiff is why I'm asking for other alternatives
Glad I'm not the only one going nuts trying to accomplish this exact same task for the exact same reason on the exact same device I'm at a dead end at the moment but I'll be sure and post if I figure something out - hopefully you'll do the same.
trying to do exactly the same thing but with GS3 with paranoid android and it keeps failing at creating ad-hoc...
any ideas? i kinda want those streetpasses XD
No luck so far, but if I get this to work, I'll probably repackage the Wifi Tether App into a "StreetPass Hotzone" app with pre-enabled Blocking for non-3DS devices and Mac Address cycling to get easy hits

I wish you the best of luck. That sounds epic. I finally gave up and just set up an extra router that was already running dd-wrt. I'll only get one hit every 8 hours with the same MAC but it's better than nothing.
trying to accomplish the same thing with a samsung gs4. same errors/results as people with nexus 4 makes me think its a 4.3 issue

Except I'm on CM 10.1, which is 4.2.2. :/
Hey if anyone happens to figure this thing out please let me know, I've been trying to do the same thing for a while now and I just came across this post. I will continue to search for a solution but if anyone finds one first please let me know what you did
Welcome to the club! I've been trying this on my Captivate with CM 10.1 with no success yet.

I'm at work right now, and haven't been able to mess around d with this, but digging through the files late last night I found in the ini file holding the macaddress (One of 2 files you need to edit apparently to spoof it) there was an option to mutate the mac for tethering usage.... The system folder is /etc/wifi if anyone wants to take a closer look... If not I'll try when I get home tonight...
Hi, i'm developing an app called StreetPass Riilay, it does pretty much what you're searching but right now it's not compatible with all the devices i invite you to check it out , it's on Gbatemp and in reddit in the 3ds subreddit.
this is a video of a test that i did.

I had that exact problem. I wound up backing up my data partition using TWRP, backing up my sdcard partition to my PC, and then doing a fresh reinstall of CM using TWRP. After doing a factory reset in TWRP I then booted the phone and signed into my Google account. I then restored my data partition in TWRP and my sdcard, and everything worked after that.

were you using a custom Kernel? honestly i dont think it has worked since i got the phone and i just recently flashed CM 10.1, it was stock since i got it. Also i am using the 4g enabler. Thanks i will try this though.
Dying to get this working.
Tried all the apps I can find, including Zurces, but no luck.
Has anyone succeeded yet?
Any news on this? It's so frustating having a theorically very quality phone and getting stucked in a simple thing like this.
still no way to spoof mac address on 4.3, even manually? what a bummer

There is a way to spoof N4's mac which is explained in these forums. Use the search feature and you'll find it.

[Q] After fooling around with AdAway I have no internet connection

I was messing with AdAway to try to get it to work on a Stock Rooted ROM, and unfortunately, was never able to get that to work. So after trying to revert the hosts file, AdAway failed for whatever reason, and then I was stuck without internet. I can't browse the internet via Google Chrome, and I can't access the internet using the facebook application or any other application that relies on the internet.
I was wondering if someone could give me a default hosts file, or if someone could help me troubleshoot why I am unable to completely connect to the internet on 3G, 4G or WiFi.
I am not above resetting the device, but, I wanted to leave that as a last resort.

If you are, as you say rooted then just use a root explorer (I use RootExplorer, also can use ROMToolbox, ES Pro etc..) to delete the current hosts file; in here /etc/hosts and then reboot and it should be created anew.
Also check your date and time settings. If they are not synched many things will not work

G2 D800 Lollipop Tethering

So just recently had to go back to stock to upgrade up to Lollipop. Everything went great. Getting everything setup and tried to go through the steps to turn the tethering check. Getting a error SQL Editor saying the database is locked. Have tried several root browsers and nothing can open the databases to be able to edit them. Have used One Click Root and successfully rooted it. Any ideas as how i can get into the database to be able to turn off the tethering check. Have also tried pdanet and it also will not work due to the tethering check. Any ideas i will be willing to try. Thanks
Attached is a picture of the error when I try to edit the database

Wifi Passwords - retrieval

Hello
Can someone help me with this please?
I have a Tab A SM-P580, unrooted tablet on android 8.1
I have used this to login to many wifi networks, and I need to retrieve those wifi passwords, to use on other devices.
I have tried the adb method, but it gives me error file not found(wpa_supplicant.conf) or permission denied(/data/misc/wifi).
Is there any other way to retrieve those passwords?
All the apps I checked are for rooted devices.
thanks
