[Q] Nexus 4 Device Administration - Nexus 4 Q&A, Help & Troubleshooting

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).

If you are using Epic Experience, the compatible version of Wireless tether is put on your SD card..
Use a file manager and find the folder called "Epic Experience" its in there. Do not install it from the market.
http://code.google.com/p/android-wifi-tether/downloads/list
pre 8 and 9 work i believe (i use 9 but i think others include 8 which works on Epic).
i've heard that after flashing a new ROM you may have to go into settings > applications > manage applications > wireless tether and clear data. might want to try that
I figured out the problem. After applying the new rom, the Super User permission got erased. The quick fix for me was to re-root with super user to reset everything then it worked again.
Same goes with a lot of other programs that needed SU permission.

How to get the KA12/13 rom completely functional for r800x CDMA users

Hey guys I'm new! Nice to meet all of you.... here are some things you can do to make this great rom even more functional on the r800x.
1. WIPE YOUR SYSTEM ENTIRELY... Data, Cache, Dalvik.. the works. Install KA12 first, followed by doomlord's wifi modules (I used the most recent test release for the 2.34 verizon upgrade and they worked like a charm.)
2. Let the system boot up.. you will most likely get some kind of error, or it may take you to the setup screen... either way, at this point, return to CWM, and wipe your dalvik cache. Next Install the CDMA patch 9 (I used the non-modded version)
3. Install google apps, and any other KA12 zips you desire to flash. When you are finished flashing, clear both cache and dalvik.
4. Now install KA13 over KA12 system meaning DO NOT DO THE FACTORY RESET.
5. You may want to reflash the wifi modules, I do not know if it is necessary, but I did it to to be safe.
6. Reboot the system, and complete set up.
7. Using root explorer, go navigate to the system apps directory, and find a phile called SEMCtelephonyservice.apk (or something very much like that).. make sure root explorer is set mounted to R/W and then simply click on this app, and open it with the APK handler or simply click install. It will tell you this app is already installed, and you are replacing it. Say ok. Now go and try your dialer. You should only get one force close after making a call now, and it should go away forever after this... No more phone force close yay!!
8. While your in system apps folder, go ahead and delete the USBconnectivtyux.apk (or something like that) ... don't worry.. this has no effect on USB connectivity at all, it still works fine... and guess what.. NO MORE FORCE CLOSE WHEN YOU CONNECT USB!
9. With your wifi connected, go to the play store and download a free app called APN manager... install it. Once you have opened it simply import the APN settings for verizon onto your phone, and reboot your phone. Once rebooted,(you can turn off wifi now) open up your mobile network settings, and make sure you have mobile network data enabled... I allowed national roaming, I'm not sure if you have to.. then click the APN settings... you should see Verizon in there now. Make sure to click that circle to turn on those APN settings.. This will get your sms/mms up and running.
10. Finally, to get my 3G icon to show up I had to redownload the SETDNS app... I got the pro version... and when I enabled google DNS, I immediately got a 3g icon in my status bar. The second time I ran through this, I did not immediately get a 3g status icon.. If this is the case for you, just simply toggle airplane mode after setting the DNS, and your 3g should eventually kick in. If you do not get a 3g icon, my understanding is that your data works even though you can't see it, however you will have trouble downloading apps.
Thanks dude.

[Q] Bypass exchange security

Hey all,
I'm coming from the Samsung Epic 4G touch ..... thankfully off sprint ......... that was a horrible 4 years of abysmal coverage .. slow speeds when it would connect .. and random disconnects thrown in just for fun....
I'm pulling crazy fast speeds everywhere I go ... Hit 50Mbps this morning on my commute..
However, one thing I liked about my samsung was that there was an APK to bypass the exchange security pin ...
Anybody know if the Epic 4g Touch (Sprint version of SGS2) APK will work on the G2? or if there is a version out there that will accomplish this ?
I saw one for the GS4 ...
http://forum.xda-developers.com/showthread.php?t=2355654
Didn't know if this would work on the LG G2 ...
Thanks in advance!!!!
Thanks guys!!!!
Are you rooted? Do you have twrp installed? If so try it and give us a yay or nay. It's not that difficult.

any ideas or is there a different way to install this APK ?
Try saving the apk then using solid Explorer or the built in file manager to find and install it. Installing from the notification shade doesn't seem to work

This is how I did it.. file explorer ... install
It just then goes to a screen that says not installed and your only option is to exit.
Xposed doesn't seem to know anything about this file.
Make sure to go to settings, security, and select install all apps or similar option

Solution
I just did this on my own before seeing your post- hopefully you will find this useful.
I used this set of APKs: http://forum.xda-developers.com/showthread.php?t=1965468
Grab Email-JB.apk and Exchange2.apk
First, you need to completely uninstall (not just freeze) the LG Email app. I used Titanium Back to do this- make a backup of the app first in case you ever wanted to go back for whatever reason. Once the LG Email app is uninstalled, you can install the 2 AOSP APKs.
I didn't try installing them normally (download->open->install), it's worth a shot- instead I used the directions in the post to push the APKs via ADB.
You should see "Success" after pushing both via ADB (I did Exchange2.apk first, but I can't imagine it would matter). Unplug your phone, open Email, and you're set. My Email is syncing perfectly with my corporate email, no lock screen password required.

YES!!!!!!!!!! This totally works..
Thank you for looking out, and thanks for posting this ... I've been waiting to be able to add this .. and having to carry 2 phones to check email because I didnt want to be pinlocked on my G2!!
My procedure -
Rom tool box free for the uninstall, the titanium way didnt work for me because I have TWRP installed .. and when it would try the recovery removal .. it would boot to TWRP instead of the stock recovery ...
Anyways, Rom Toolbox free has an uninstall utility, couldnt be easier .. uninstalls without a reboot needed.
Turned on wireless storage, copied over exchange2.apk and Email-jb.apk and installed through android .. didnt use the ADB method .... it works perfectly!!!!!!
Thanks again.
That works. Only downside is it removed the feature of peak and off peak for message retrieval. oh well.

Tried this several ways, but it does not install. Can u give some more direction on this? Do we put itf in the apps folders? Flash it? Any advice would be appreciated. I like the lg email app and don't want to go back to the stock one if possible.
if someone figures out how to do this with the stock email app that comes with the att version, that would be awesome. I like that version better than the one you have to install to get this to work.
I really hate having to use a pin, but I have to give my work permission to remote wipe my phone. Is there any chance this could be flagged by my employer and they remote wipe my phone? That would really suck because of the lack of memory card. Anybody that has been remote wiped, did it affect the entire phone, or just the main system?

Phone Hacked with Spyware Remotely ?

Hi,
My brother has been told by an associate, that he has hacked his phone and can track and hear everything he does and did it remotely.
Also said the App is undetectable.
His phone is a rooted Note 3 and his wife has a non rooted Galaxy S5.
Now, I have told him there is no way for for somebody to remotely install any app on your phone even if it is rooted, unless it is already compromised and or unless they have your Google account and password, which i am not 100% sure that would allow you to install anything either.
So my question is, if he flashes an original rom and creates a new Google account, can he feel safe that his phone can't have malicious apps installed with out his knowledge ?
I would assume a factory reset wouldn't be enough to get rid of an app installed as a system app ?
Is there any programs he could install to check for malicious apps.
I think my brother is just being overly paranoid and this guy is a ****
Help greatly appreciated.
Hopefully this is the right thread / board, if not please move to the correct thread please mods.

I would say, scan with an antivirus like avast and see what can come up, and to your question, if he flashes the stock rom, everything which has been installed as a system app will get removed, also if your phone is rooted , avast has a function which is called firewall, in that you can control the internet connectivity of all the user/system app. I use it to block internet access to systems which in my view do not need any connectivity to run. Its very easy to do also. ask him to change his goole password and also user 2 factor authentication on google.
Sounds like someone's been watching a bit too much Person of Interest...
Do such 'apps' exist? Yes. Are they publicly available? Hell no.
I dont think theres a software like that in public. Thats a lot of money to be earned "IF" ever and theres laws to break.
Just do a factory reset from recovery or a better solution is to upgrade your firmware to the newest build from samfirmware
Factory reset won't delete system apps.
The least you can do is flash stock ROM using Odin to fulfill your brother's OCD.
Thanks guys, will put my mind at rest and hopefully his.

1- Yes. And no need to create a new account, just change the password of the current account.
2- Yes, in some (rare) cases.
3- I'm not sure. You can try some antivirus apps or security apps on the Play Store. But in general, you can check yourself by finding apps that have the following permissions: READ SMS + RECORD AUDIO + FULL INTERNET ACCESS... Try to eliminate well-known safe apps, plus some experiences and some helps from the other, you can identify these malicious apps.

disable automatic updating?

last night i was using my nexus player and out of nowhere it just randomly decided to shut down. next thing i know upon reboot it tried to update but since im rooted and such it failed. the problem here was that it screwed up boot and i had to wipe the cache which erased most settings.
Is there a way to make the nexus player not try to automatically update? disable update in settings for that matter (in case someone tried to get cute and do it while im not around)?

LOL!!!! I'm going through this frustration right now. Couple things I've done first install a custom recovery it won't let you update. if you do get the endless bootloop clear cache and it will stop (the update is downloaded to the cache). It might do that twice then will pass. This worked for me until factory restored my device. I ended up forgetting and now I'm marshmallow.
Next thing I'm gonna try is pushing a build.prop from the next update to /system. It hasn't been pushed yet but they usually release it on the site with the factory images. If I don't flash aosp first.
Yes but i wonder if theres a way to disable it. it sucks that i have to clear cache every time it attempts to update. its happened 3 times on me now. i will try to install my own custom recovery so hopefully thats all thats needed but i noticed android also downloads the update in the background, which probably wastes more space if your not planning on upgrading.
Once you clear the cache it deletes the update. Almost forgot I read some where here on xda that deleting otacerts.zip will stop it from downloading entirely. Not suggesting you try it but next update I'm gonna
You might want to try the method I suggested at http://forum.xda-developers.com/showpost.php?p=62865084&postcount=6 and see if that works or not.
Thanks for your solution but unfortunately, at least for me, i cant seem to get it to work. i can sideload and launch the disable service app, but when i try going to ANY actual apps or system services, it just crashes. Not sure why. :/

Tried this, and while it did stop the download from verifying, it just caused the nexus player to loop over and over by constantly downloading the update again, only to fail and repeat the process. This worked for a couple of days while i found the proper workaround, so thanks. keep in mind though that because it just caused the device to keep redownloading, this method could cause those on limited data plans to quickly go over.

for whatever reason service disabler did not want to work for me. it caused a constant crash every time i tried clicking on any service within the app. I did however, eventually come across "My Android Tools" by the same developer as service disabler. Using this app i was able to disable the systemupdateservice within both google framework and google play services. I had to use a bluetooth mouse to navigate though, as the remote didnt want to work on its own. Once i used this app and followed your directions, now when i attempt to do a manual system update in settings, it just acts like im on the current version, which i assume means it fails instantly. Thanks so much man! so far so good!
For anyone curious, the app is:
https://play.google.com/store/apps/details?id=cn.wq.myandroidtools&hl=en
keep in mind you may need to connect a mouse somehow to the nexus player to navigate and disable the services.
Thanks I'm gonna downgrade today and find out

I'm glad to hear that things worked out for you with this method and the alternate app by the same developer. I've been running Android 6.0 Marshmallow after flashing its factory image but once the monthly security updates and unwanted reboots in to TWRP start happening, I may disable the updates using this method.
How do you sideload either service disabler app? Neither are listed on apkmirror and searching the play store in browser doesn't give an option to install for nexus player.

Copy and paste the Google Play URL for the app (which was posted earlier in this thread) in to box at the top of https://apkpure.com/region-free-apk-download and press the green download button. Then upload the APK to your Google Drive account and install it through ES File Explorer on your Nexus Player.
please correct me if I'm wrong
As the title said, please correct me if I'm wrong but this method isn't working in the nexus player MRA58K since the apk used to disable the updated only supports Lolipop, I tried in my nexus 7 running 5.0 and it's working flawless but the apk crash on Android 6.0, thanks in advance for your help.

Not for me. After granting "my android tools" access, I go to disable systemupdateservice, and popup says it can't access root privelages ( Supersu is up to date. I'm not really sure why I even rooted and installed twrp recovery on this device, but I wish I had stock recovery back so I wouldn't be in this mess.
@pokes135, make sure you have the latest version of My Android Tools installed. You can flash a stock system or recovery image using Nexus Root Toolkit if necessary.

You can install a firefox browser addon called apk downloader which will inject a button when you view the app in google play website to download the apk.
Use any root explorer or es file explore
make/mount system as rw
navigate to /system/etc/security
rename otacerts.zip into otacerts.zip.bak or whatever you want.
It will stiop the automatic update completely.
If you need ota update you need to rename th otacerts.zip back

Thanks for the info. Much more straight forward to do then sideloading app while hoping the app won't force close.
adb connect 192.168.xxx.xxx:5555
adb shell
su
mount -o remount,rw /system
mv /system/etc/security/otacerts.zip /system/etc/security/otacerts-disabled.zip
mount -o remount,ro /system
Pr-requisite: must be rooted and ADB Wireless already installed.
Don't use this method (renaming ota_certs)! It will just cause the updates to continuously download and fail, then start downloading again. You'll use a lot of bandwidth this way, and if you have a data cap, this is a sure fire way to bust through it.
