So one day, my Nexus S randomly decided not to have a data connection with my carrier (Wind Mobile) anymore.
Wifi works, mobile data does not.
Steps I did to try and fix this:
1) make sure APN address is correct, which it is.
2) turn airplane mode on and off
3) toggle carrier connection on and off
4) factory wipe phone and reinstall ROM (slimkat)
5) factory wipe phone and install a different ROM (AOSP)
6) flash new radio (KB3 and KB1)
Other things I tried:
1) tried my SIM card with another phone (Blackberry Curve), data connection seems to work fine on that phone.
2) Called Wind Mobile and asked them to reset their towers to my phone... all they did was remove the Blackberry security thingy
that I had with them when I was still using a Blackberry. Rebooted my Nexus S, tried again... still no data.
So... I'm at my wit's end, and I have no clue how to fix this. Any ideas? I've found a couple similar threads for this problem... non of which had a solution to mine.
I remembered I made a backup nandroid a little while ago... and I restored it.
Voila, everything works again. But as soon as I tried reflashing to my preferred ROM (Slimkat), the problems started up again.
I also forgot to add that before I started encountering problems, my phone froze and I had reset by doing a battery pull because it wouldn't respond to any key presses. I'm guessing it corrupted something, though I'm not sure what. I've diagnosed that this is not a hardware issue, and that it's purely software... I'm not sure why the problem comes back when I reflash to another ROM. I'll keep you guys posted.
One other thing worth noting is that when I have Slimkat installed, it doesn't seem to read off my SIM card properly.
The APN doesn't get named "Wind DATA" like it usually does when I install a different ROM on there; it just gets named "Internet".
I didnt root or unlock it myself.... im pretty sure i wiped all data before flashing the rom i have on there now, but i cant remember for sure....
seems to be the only way to truly fix my extremely messed up WIFI situation... (wifi kills my phone completely... regardless of whose internet as i tried my neighbours and got the same error). i did a restore to last year but it only fixed it for a day... if im gonna restore to a year ago again, i figure i may as well do a full fresh install, since its crapping out still anyway
i have something called superuser (i know is root access), and something called stk which ive read is sim toolkit, in "system/app" they are both apk's. "superuser.apk" and "stk.apk"
also, will my custom recovery be gone? as far as i remember that is how i flashed my ROM last time... but its been so long i cant remember...
Let me try helping since myself new on forums:-
There are two types of phone resets available- 1.Factory wipe from settings of phone/from custom recovery (cwm/twrp) or 2.Complete wipe performed such as in upgrading os version of android (like i did lollipop from jellybean). The complete wipe is done in custom recovery only under mounts and advance option in cwm and then wiping cache,system,data and everything else. If you do so,you will be losing everything installed in your phone EXCEPT Root and Custom recovery.
Back to your question, if you perform factory reset,NO,you don't lose root. If you do complete wipe from recovery,still you don't lose root of your phone UNLESS you fix the root on reboot.
Choose the reset carefully before installing any rom,read their steps,if they ask full wipe or just factory reset and dalvik cache.
Hope it helps.

you cannot unroot yourself thru factory reset

Factory reset WILL:
Remove all apps and their data
Contacts that are not on the SIM card
(In some rare cases) Pictures, music...
Factory reset WILL NOT:
Remove carrier unlock
Remove root (but may remove superuser app)
Remove the recovery
In case that superuser app is gone, just install that same superuser app from Google Play and update it if it asks to do so.
Ok, let me ask this, to ask if its even worth me doing....
last night i did the same restore to a year ago... except this time while i still had wifi i had downloaded both avast and AVG
I can with both now, and my phone says its clean...
but yet the problem is recurring now, and wifi, 4g, tethering..... basically any function that connects me to the world outside completely craps out my phone...
i thought the restore, and especially he restore and downloading antivirus would fix it, or at least be able to tell me WHAT the problem is... avast will scan the wifi network, but of course this test now freezes up just the same cuz it has to turn on wifi to do so.... while it was still working this test did execute just fine with no errors....
its as soon as internet is connected... for 3g or even my router, it will read it without the internet feed plugged in. but plug that in and it all goes to crap again. Id just hate to do a full fresh install just for it to all go to crap *again*....
ive scanned all computers on the router and those come back clean/no viruses... i tried i different router with internet, same error. i tried the neighbours connection.... same thing again.
this is really baffling.
so i feel more comfortable doing a factory reset....... but i guess im wondering is will it help me??? at all????
whatever this is is clearly not an infected device as some on another forum had thought.... something *else* is going wrong....

Factory reset fixes all problems that were not made with root. You will not lose root either. For a total fix just wipe everything and reflash rom.
Right now im trying a different router, which doesnt have any windows XP machine plugged into it, and i made it extremely secure. even changed the default username and password to get onto the router itself (never bothered with the other one, the one i had been routinely using)... I did a complete reset of this router before even connecting to it with my phone, after it was secured. the other regular one still has everything else connected to it. this one is literally a separate connection, which i named "phone test" lol.
if it makes no difference, total fresh install is my last resort. if it *does* make a difference however... then something in my other regular router is messed up that cause my phones connections to freeze up - but that avast or AVG wouldnt detect (thats the only weird part)...
i even did a scan of my external SD card the other day, thats clean too.
time will tell, im approaching the 24 hour mark with this new setup. if by tomorrow its freezing up again, its not the router. but if its still working, ill have extreme suspicion that it was in fact, the router, probably something dealing with my XP machine thats plugged into it (well, normally anyway).
Time will tell...
im also trying to remember which apps i had updated before any problems started in case there are any corrupted updates i installed, without knowing it. (legit from play store, but still, ive heard that doesnt always mean totally safe, cuz anyone can make them)
Dude, wipe data, cache, system, reflash rom on your phone. BUM, problem fixed.
I still may, but i wanted to play around with the routers first to see if i could fix the problem.... that way id know i wouldnt be fully wiping for no apparent reason. if in a week or so things have been fine and i try connecting to the old regular router... than ill know its something on there infecting my phone... id rather not have a fresh install crapping out on me.
You can do a nandroid backup and then reflash everything. That way if you screw something up or the problem is not fixed you can restore in minutes.
The update to Android 10.3.1 on my OnePlus 6 appears to have broken connecting to bluetooth audio in the car. I have had it connect once or twice with much fiddling but most of the time it will cycle connect>reconnect>connect etc. I've tried removing and repairing, connecting as an audio-only device and not a 'phone' (an option the car gives me) and even a full factory reset on the device with no joy. There doesn't seem to be anything in developer options that might help either. Anything I can do to try and debug this? It's seriously annoying being without audio in the car. I've raised a ticket with OnePlus but I'm not holding my breath.
Thanks

After you applied the update, did you boot into recovery and wipe the cache partition(not factory reset, just wipe cache)? Sometimes there is stuff from before the update that causes issues with new system(especially if the update is a newer android version than what you had), wiping cache fixes that. Sometimes it is even necessary to factory reset the device if wiping cache doesn't help.

My EV PAD 5 was acting up giving me an error 708 which didn't allow me to watch anything, so i factory reset it.
However after factory resetting it and logging into the wifi, which did connect, i was unable to actually use the internet.
If i press 6868 on the remote it tells me ''error 1004'', and if i go on google to go to 6868hx, it tells me ''you're offline/not connected to the internet''.
But the thing is, i did connect to the wifi and when i go to settings, the wifi does show up as connected and my wifi works, so what can i do at this moment?
Would appreciate the advice. Thanks!

What does an android phone have to do with an EVPAD?
Hello,
I have a ZFlip 3 that will sometimes boot up properly, and then work fine until it turned off again. But sometimes the phone will boot to the "Samsung Galaxy"/"Powered by Android" screen then turn off.
The phone is fully stock/non-rooted.
Any ideas?
Thanks.
Try clearing the system cache.
Try in safe mode repeatedly, buggy 3rd party app. If so find it.
Did you do any major firmware upgrades without doing a factory reset afterwards?
Did you use SmartSwitch?
If so factory reset; do a clean load and don't use SmartSwitch.
Look at the Log files or...
A Samsung Experience center at best buys can run advanced diagnostics on it if one is convenient to you.

I have had this exact same issue with mine, but when I took it to the repair place they said that the phone had nothing wrong with it. my theory is that some internal process is sending large amounts of data to the cache, its strange because even if I factory reset and clear cache it still goes back into the state after a few hours.
