[Q] No wifi after factory data reset - T-Mobile Samsung Galaxy S 4

i did a factory data reset as I'm giving my mom my s4 and taking her nexus 4 so after i reset it the wifi stopped working, I've ref lashed cyanogenmod 3 times now none of which works, what i don't get is that wifi was working fine before the reset, does anyone know how to get this working again? thanks in advance

I'm thinking this is an issue with cyanogenmod because i flashed danvdh's 4.4.4 stock based rom and it works fine now, id say CM is fine but there are some problems that still show up every now and then

Please can someone help

Hi all,
Not sure if anyone can help.
I have seen loads of posts about the com.android.phone has stopped working problem but none are like what happens to my phone.
I have a rooted note 2 and running jedi x17 rom (4.1.2 based on the standard touchwiz) all works fine no problems.
I want to go to a 4.3 rom like cm/pacman/pa etc but whenever I flash the rom and reboot after 2 min the com.android.phone has stopped comes up, but only once after I reboot, everything works fine and I can get on the Internet and make calls etc, it's just annoying.
I have even gone back to unrooted stock and started again but the problem still happens, any help would be great.
I'm on the EE network in the UK, I was wondering if Apn settings could be a problem.
try after flashing to wipe cache and do a factory reset, see if that works.

[Q] Maguro, Wifi is not working at all, suddenly. Help please, ideas?

I was connected to my wifi, left my phone alone for a few hours, and when I came back (yesterday), i saw the wifi not connected. I go to try and reconnect it, and it says wifi turning on, and nothing else happens, it is stuck there. I can not get it to connect to my wifi. Any idea what could cause this? what can I do?
Gsm galaxy nexus, paranoid android 3.99 android 4.3.
mobile data, calls, text, etc all work great, only problem is wifi seems to be stuck. I tried rebooting, but still nothing.
Any ideas, and thanks for your help.
Been reading other threads. Going to make a nandroid backup and factory reset this baby see if that works. I will let you know. If not I will try another room or go back to stock. If anyone has any other ideas highly appreciated.

Factory reset, nothing, restore previous nandroid from 6 months ago, noothing. Still stuck at turning on wifi, but nothing more than that happens. Would screen shots help I can post them. Last resort going to go back to pure stock see if that fixes it.
If not I am guessing hardware problem? anyone have somthing similiar happen, and what did you get to work if anything to fix it? or is my wifi module fried? Thanks any who have input.
OK, update, nothing I did work, android 4.1, 4.0, 4.2, 4.3, factory, stock, custom, cyanogemod, paranoid, nothign solves it.
I suspect my wifi module dyed out. anyone else have something similiar happen?

Could indeed be your wifi antenna. Had a similar experience with a T-Mo MyTouch3G a while back. Same symptoms.
Are you clearing all caches, factory resetting, and wiping the system partition from recovery?
Last case, you should restore to absolutely stock, relocking your bootloader and everything.

Awesome, thanks for responding, was beginning to wonder if anyone was reading it
What I tried so far (each time wiping dalvic cache, cache, and doing full factory reset from both within android and cwm):
Factory reset on paranoid android 3.99 android 4.3 = nothing
Install cyanogemod 4.3 = nothing
Restore my nandroid backup of bixie deodexed stock rom (which i used before going to paranoid) = nothing
try other version of android from 4.1, 4.2, etc. on varion roms = nothing
restore to google stock (as far stock as possible minus locking bootloader, means yes, stock recovery and everything), 4.1, 4.2, 4.3 = nothing.
ran out of ideas, learned alot though, and got more flashing experience than I care. Did learn how to adb backup, more about android backups, etc though. Some good has come out of it, but my original problem of wifi was and is still not resolved.
Unless there are other ideas, I am pretty convinced the wifi antenna/module died (and a google search confirms others have had something similiar happen, they had to replace the pcb to fix it, which is costly where i live, Argentina). So may just use it sans wifi until I get a new phone, thing has a couple years anyway and nexus 5 is about to be announced.
But I am open to any and all suggestions least I still have hpsda+ speeds 70% of the time.

somebody Help~~
This thread is over a year old, but I'm having the same problems lately. The device was reluctant to auto-connect to known wifi networks, which I attributed to the current and latest CM11 snapshot. Then, a few weeks ago, the phone became unstable, with random reboots 3 or 4 times a day. Clearing cache and Dalvik cache didn't help. I didn't want to do a full-wipe, with CM 12 on the horizon. About 2 days ago all wifi reception stopped. I could activate wifi in the software, but the device wouldn't receive any signal at all (checked with Wifi Analyzer). So I was afraid that the wifi died out permanently. This morning, in a last attempt I switched off the phone and took out the battery for a couple of minutes. On restart I was surprised to see that wifi found a known network and received an ip-address. However, an internet connection never established and the menu reported a bad reception. I then de-activated and re-activated wifi, but that didn't bring me any further. I guess I'll wait for the first CM12 nigthlies to find out if miracles still exist.

[Q] network problems

Hi, I have i problem with my mobile connection.
I have been using liquidsmooth v3 for a couple months without any problem. It started when i started trying 2 stockbased roms : romaur and kitslim. I wasn't able to get mobile data working even if i tried to configure it... download mms settings, choose provider... So i decided to get back to cm, aokp... I tried lots of them : carbo, pacman, aokp, aicp... new problem. at that point mobile network worked, but i was always loosing all network connection (not just data) about 30sec each couple minutes... then i decided to restore my liquidsmooth backup. It helped a little bit, but i am still loosing connection from time to time : about 30sec each 30 min...
Right now, i just reinstalled aicp 4.4.4 r2 5.0 and moshkernel as a last attemp, but it is still not working properly.
I know all this is not very clear, but i need help!!
In the process, i installed and flashed many roms, kernels and recovery...
my question actually is what could affect my mobile connection in all that? in time i installed a new rom, i wiped data and factory reset the phone.
i remember on my samsung there were modem you could flash...?
hope someone understands my problem et asks for more info..
thanks
Flashing a load of modded ROMS wont make trying to find out any easier so you need to flash a stock ftf and do a full wipe of your Phone, I'd even wipe your SD and start from scratch.

[Q] ParanoidAndroid 4.4 - Wifi wont start

Hey Guys,
i installed ParanoidAndroid 4.4 on my i8150 ~2 months ago and everything worked fine so far. But yesterday the Wifi stopped working. When i activate Wifi in the settings, the button gets grey and nothing happens.
I tried a hardreset, wiped Cache and Data and flashed the actual version of the rom but nothing worked. Wifi is still grey and i cant activate it.
Does anyone have an idea how to fix this problem?

Help with wifi on my s4

So I just updated my samsung galaxy s4 yesterday with kies but after updating it doesn't let me turn on wifi at all whenever i press the wifi button it just goes back to off can anyone help me?
Try re-flashing the latest stock ROM with Odin. Factory reset if re-flashing doesn't fix the issue.
Does everything else work (calls, text, data, Bluetooth)?

I have the exact same problem, except I reflashed back to stock using ODIN. A factory reset even directly after a clean wipe doesn't do the trick. However, one thing to note is that I can turn on wifi on any other ROM except stock, so it can't be that the radios are busted.
