My bad,i didnt explain it very well.
I did that,i have seperate section called Developer Options,but when i press it settings app crashes.Bluetooth isnt working,half the stuff doesnt work,and i cant access usb debugging-

My guess is that when you did a factory reset, the additional package with the others app has been deleted.. try to flash it again.

I have got the same issue. What do you mean with "additional package"?

Did you, by any chance, flashed a custom kernel to get root?

Same thing here except after a factory reset my display settings were fine but after the set up in the settings it just crashes the app.

thanks for your reply. but I can't even launch the market app. as it close with forced close error.
the device is dead. it can boot normally. but every and each app is closing with application error.
I can't even perform factory reset. as it doesn't seem to do anything.
I can't install any apps from google play as it is crashing.
hard reset not working too.

this same thing happened to me yesterday when i was trying to download stuff from xposed, it said downloading error 504. i didnt do anything with my phone like the guides tell u. they say delete cache and data and etc from play store app in app manager. i didnt do that.
this is what i done- i disabled mobile data as i was using wifi but i generally just keep it on just incase . then i fully turned off my router and then switched it back on. then i made my phone forget my wifi and then i set it up again. then everything was fine and all was back to normal. i heard this happens sometimes, dont do any big steps just be patient and it will sort out with time, as its a gateway error and nothing u or the service can do about it- i know this according to what ive already read. :good:
ok, thanks nayanwaghmare, but my problem is a little diferent, I can download, apks, from any source, but when I reach the screen where you see the permissions an the options to cancel or install, the button for.installing does nothing, only the cancel or back work, only the play store has no problem, as it installs automatically, I dont know what to do
reflash your rom i would say
I will try that , thanks

Do you have any screen overlay app running, like screen filter or lux? You need to disable those to be able to click the "install" button -- this is a security feature in android.
thank you very much!!!! I just solved the issue, thank you very very much man,

Developer Option cause settings FC

Hi all, I have the original european version untouched, just updated to B03 version.
After i enabled the developer option clicking on the build number, i can see it in the the settings but it doesn't open, it just FC.
Anybody know a way to fix it or to clean the settings data do i can do it again?
All I need is to enable the USB debug option, is there any other way to enable it without Dev options working?
Tnx in advance
You should do a factory reset..
I hoped there was a less drastic solution..
Tnx anyway
I did a factory reset but the problem is still there...
I cannot believe that only me have this problem...

Tnx
I downloaded the full image and flashed it but i still cannot go in dev options
It always FC settings.
I'm out of ideas now
Same issue for me, I think it's a common problem for the eu version. Hope they will fix it with the next update
Same here.... i think its a b03 issue. I used developer options in b02 and it was fine.
I used b03 and could go into developer options and disable/enable USB Debugging without problems...
I'm not sure if it's a common problem. Did you try to connect your device to a pc and go into developer options after that?

[HELP] Force close with substratum, unusable phone

So my father decided to update with substratum enabled and now we get SystemUI FC every time and can't use the phone.
No rooted, no custom recovery, no nothing. Is there any way of removing the overlays without wiping data?
Thanks.

You can try going to Safe Mode:
1. Reboot your device
2. Hold down the Volume Down key while booting up
3. You are now in Safe Mode
4. Go into Settings -> Apps, then find the overlay you think is messing up and uninstall
I'm afraid it makes no difference

OK, I read this 'tutorial' here on XDA. Have not tried myself but see if it helps. If it works please report back. It would be nice to known for future reference:
How to recover if the above doesn't work? (Credits to Evozi)
You will have to boot up in Safe Mode (comes default on every device)
1. Turn on screen and press power button. It will show "Shutdown", "Restart", "Emergency Mode"
2. Turn on "Emergency Mode", keep spam the checkbox so you can tick the checkbox to proceed the agreement. (phone is super lagging)
3. While you are in emergency mode, you have very limited access. Open any system app and go to recent task list.
4. Long press the app task, press the info icon and app detail page will appear.
5. Hit the back button and it will show your whole app list.
6. Find your overlay and remove all its storage and phone permissions.
7. Deactivate Emergency Mode and now you are back to TouchWiz.
8. Uninstall the overlay app.
Can't check the agreement with th fc window all the time, any trick for that?

Can't access developer mode

So I wanted to cheat my location with mock location. And to do that I need to get in the developer mode settings which I havent been able to do.
I started with tapping the Build number and the information I got was: no need, developer mode already enabled. But it is not visible, I've checked a million times. I then went onto deleting all data and cache from the "settings app". Nothing changed. I restarted the phone, nada new. I downloaded the app Nova launcher to create a shortcut/widget but developer mode did'nt exist there either.
I'm out of ideas. What can I do?

Try a hard reboot.
Clear system cache.
Try safe mode.
Factory reset.
Reflash firmware.

Tried the first three suggestions. I guess I'll be moving on to a factory reset.

That's bizarre. Try Googling it first.
I really loathe using factory resets except for boot loops, viruses and old loads.

I agree. I Googled it all day and it seems like I am the only one with this problem. I saw someone fixed it with the Nova Launcher app, but it just doesn't appear there either for me :/.
