GT S-7562 WIFI authentication error

Hello to every one...
I just decided to recycle my Galaxy GT S-7562 as an emergency phone but after an update to 4.0.4...
it doesn't want to connect to a wifi anymore. I always get authentication error...and the funny thing is that
the same happen even if i try to connect to an open network...!!!!!
Don't really know what to do...Anyone else have experienced it?

Well, Putting myself in your place, the first thing I would try is boot into recovery and wipedata/ factory reset wipe cache.
restart and check again.
if even after that It doesn't work
flash firmware through odin.
although I would not be dealing with this problem directly cause I don't know what exactly is causing this. So the easiest part, flash.

First off THX for your answer...
Billysam I already tried all the above with no luck... also flashed the firmware a couple of time. Last thing i did was to install
CM11. I'm starting to think that i could be an hardware problem....but well it doesn't look like..

I am uploading a whole zip file with everything that would hopefully return the device to factory default. my upload speed is pretty bad and its already an hour maybe another 5-6 hours and it should probably get uploaded. as soon as it get uploaded I will update my post and will share with you all.

Even after completely flashing to default through odin, I would say don't flash anything more. its not the software's fault
There are 2 things now
Your router settings. for this there are many things that could make problems
1. First Check wifi password and be 200 percent sure that you're entering the right password.
2. Check at another place, another wifi. I also had trouble connecting at my friends wifi, it would keep returning with authentication error, but the same device connected to mine router without any error. (I still couldn't confirm why it happened there, I suspect my friend had blocked my device in router settings or gave me the wrong password)
3. Forget network, turn off your device, turn off your router, then turn on your device and your router , open wifi in device enter password again and connect.
4. Make sure bluetooth is off and only wifi is on.
5. Check if your Mac ID is not being blocked by the router (find MAC address in your device settings-wifi-advanced) enter your Router settings >>wifi>>MAC Filter disable the Mac filter.
6. Go into your router and go to advance and under wireless go to wireless card list and click set up access list ...add your device with the mac address.
7. Reset the router.
8. Change the security settings on the router, from WEP to WPA2/WPA or vise versa, change SSID name as well.
can connect through WPA push button?
9. Try changing wifi channel to 5, 6,7,8.
10. there are few app in play store that say they can fix the wifi issues one such app is wifix, try them too.
Even after going through all this it doesn't work, then I feel there is a chance that wifi module is at fault and the part would need to be replaced.
there are whole lot of people on the internet that have faced issues and are facing issues with the wifi be it any device,(same goes for the wife ) Guess it has a mind of it's own too.
Well best of luck.

Ok Thank you very much for your help....
I already went through what u suggest before to post my 1st msg...with no luck.
What i find strange is that i'm not even able to connect to an open network..and
still i believe that it has nothing to do with the hardware....
Auth error on an open network is weird....anyway...
THX
David

I'm facing the same problem ... authentication problem occurred... even on open networks.
flashed stock rom
still problem exists

Will this procedure clear data? Factory reset?

Can someone please confirm if this clears existing data? I thought Odin doesn't work in this case because of the locked bootloaded on Verizon?

Yes, it probably will. If you are that worried about it, backup your data first. Odin will work even with the bootloader locked. Locked bootloader does not prevent you from loading official firmware.

What app can we use to back up all data like apps sceen layout ect... since we don't have root on Verizon, I know we can't use titanium back up because we don't have root bit is their a similar app to do what that does

Not sure you'll be able to preserve that. I was referring to user data, not system data.

Helium or My Backup Pro, but they are limited without root, which means some data can be restored, but not all.

I extract and I get several files? None of them being .tar files. Does anyone have the 4 files to flash in odin? Am I the only one who didn't get the 4 files mentioned when extracting the Md5? Any help would be greatly appreciated.

Nobody?

You have to go in odin and select PDA and then add the entire md5 file! If you don't want to do it that way, then you have to download a zipping app like 7z or similar and create the .tar yourself.. Which is pointless unless you're planning on flashing 1 file like the boot.img for a reason or other.. The md5 file has all of the files that need to be flashed there's no need to unzip the files. Just flash as is!
If you're downloading from the OP then you need to unzip the file from the .zip because you can only flash .md5 or .tar.

Try flashing a modem only file then which is for that signal.. Also boot into recovery using the 3 button combo and clear your Cache after a flash..

I've cleared it after flash and no fix. Does anyone have a modem file I could use. Does it have to be from the same firmware version? Sorry just not really experienced just need to fix this phone it's killing me. I got it off Craigslist don't know the history of it I just know that flashing a fresh stock rom didn't fix the issue.

Is it an actual Verizon phone? And do you know for sure that it's Verizon? Go into settings then about phone and tell me what model it says. If it says other than SM-N920V then it's not a Verizon one.. You can only flash firmware for a specific carrier.. Also check the APN settings too.. And about the modem no you don't have to use the same exact one from the same firmware version you can try a different one however I don't think that'll fix the problem.. Try checking the APN settings first.. Also if you just dropped a sim card into it without first giving Verizon the IMEI then it's not gonna work! You'll have to give them the IMEI and if the IMEI is bad the phone will never work at least not with Verizon.

It is indeed n920v clean imei through verizon prepaid. It gets apn through SIM card which is accurate I have signal T all times and internet/mms work. However when I boot my phone or randomly every so often it will say 'searching for service' throughout the day while still full having signal. During this time I don't receive calls/messages/internet notifications and it is stuck that way until I notice it and dial my voicemail which it then displays "Verizon wireless" and then all notifications come through.

Maybe try using this downgraded version from my Android File Host and flash it using odin but before flashing take the sim card out and after it's done flashing immediately do a factory reset by holding the power and volume down button and after the screen turns off and then back on select shut down and then boot into recovery and do the factory reset after it's finished put the sim card back in then turn it on and go through all the setup and see if it works.. Let the phone charge some first don't try doing this at 3% battery cause if it shuts down in the middle it can brick the phone. Not likely but it could.

Please help me!!! I'm in need of assistance

I just bought a galaxy s8 plus phone. The Wi-Fi keeps saying turning on, but doesn't actually turn on. It's not my router because I can get my galaxy s7 phone to connect no issue. It's a Samsung G955U and 7.0
Any thoughts?

You can try a factor y reset and or stock firmware
Reinstall. Sometimes stock can be broken as well.

First you need your firmware. Which can be found in about phone and baseband.

Mine is Verizon. SnapDragonG955U. I found the firmware for my phone. Can you direct me to the thread where I can flash the firmware for this phone? Ive found a thread for rooting that is part cyborg. It looks like I can use that to root the phone. But I need to reflash the stock firmware first.

Only other thing I know to do is try a couple firmwares and maybe one of the combo files around. If none of that works then a ram with Sammy may be the only option. As this is about everything you can try on your end.
Unless some one else wants to chime in with something I didn't think of.
Ps I had this happen on my LG g3. Camera could not connect. Flash many roms. Flash this that. Nothing. And all because they used apparently the same base I had. I bricked. Or something downloaded a new firmware from a new site and flashed and bam. No camera issue from there on out

Need help to diagnose dead G920F that only boots to download mode

Hey i got a Samsung Galaxy S6 that only boots to download mode. I feel like I have tried all the methods already listed in the many other threads but nothing is working in my case. I saw a comment that mentioned that the motherboard is dead but could that be it? If I unplug it while it's "downloading" it's shows that i have to connect it to Smart Switch blah blah, so the phone knows that something went wrong it the download progress and I just don't think it would be able to if the motherboard was dead...
So what is my problem and is it fixable? Any help would be appreciated
edit: The current binary also changes from official to custom if I flash twrp so the phone knows that i've downloaded it. So I dont think that a dead eMMC is the case either. I can't get the phone to shut off if I leave it then it will get stuck in bootloop. Only way to shut it off is to drain the battery... :/

Yes but am still facing the excat same issue as I did before, where odin passes but I won't boot. The only change is that message.

I am facing similar issue. I just wanted to reboot device and it stuck on samsung logo. Flashed odin passed everything fine for 3 weeks. Another reboot and stucked but now stucked even after odin flash. I flashed twrp and lineage 16 then back to 14.1. Some programs say that everything is OK with device. Memmory and all. I just dont know what happened and why. I would really like to go back to stock but now I am just not sure it will happen AGAIN.

Question WiFi and Hotspot services stopped working after the latest update on my ROG 5.

Wifi and hotspot services stopped working after the latest update of ASUS ROG 5. As soon as I tap on wifi to toggle it on it switches back to off. Please help. I am not in my home country to avail warranty. The Wifi MAC address is unavailable. Please refer to all the screenshots and let me know if any further details are required.

You forgot to add screenshots.
Anyways, just give it a factory wipe and see if that fixes things?

this might be a weird solution but why not give it a try, if you are rooted. Use this app and get yourself a new mac address. The wifi fails to start due to a missing mac address.

Asus told me that I need to send the phone to the service center to change the motherboard. Many have faced this problem and get it solved by changing the motherboard from the official Asus service center. It is stock without root as it is under warranty period. I need some suggestions regarding this. First, should I try to send my phone to the home country to get it fixed or should I root it and install a custom ROM. And if I apply a custom ROM, will my problem get solved?

Seems like either your baseband dropped or your efs got lost somehow... You might want to check to see if you still have imei

If they are willing to take it in and fix it for you then go for it, its much easier if you don't know your way around android yet.
If you feel like experimenting then sure why not? Flash a custom Rom and see if that helps since you have IMEI intact but make sure to take a backup of it.

Wifi and hotspot services stopped working after the latest update of ASUS ROG 5. As soon as I tap on wifi to toggle it on it switches back to off. Please help. I am not in my home country to avail warranty. The Wifi MAC address is unavailable. Please refer to all the screenshots and let me know if any further details are required.
