After the factory reset and during the set-up that follows on reboot, does it prompt you to set up a wireless connection? This should usually the second step in the set-up process.

Glad to know your phone is now working normally. If you are on stock 4.1.2 getting 4.3 OTA update should be a breeze. If required, however, I would suggest you take advantage of the flexibilities offered by the lower firmware especially free unlocking before updating to 4.3

WiFi issue after ota tab 3 7in SM-T210

Hi all i recently bought a no fault customer returned tab 3 7in SM-T210, Today I received my tab 3 and after the first boot I was offered an update, Build number KOT49H.T210XXBOA3, dated 22 jan 2015 at 110mb.
After the update had finished I was unable to connect to my WiFi, it would say connected but the settings app would freeze sometimes with the message that settings is not responding, if I do manage to get out of the settings I am unable to use the internet as all apps say no connection, even though the WiFi icon is showing as connected. I have also found that changing the screen off time to 1 minute cause's the device to soft reboot ( No Samsung galaxy tab 3 screen / bootloader )
I have tried doing factory reset but that didn't help,
Could flashing the full 828mb stock ROM via Odin possibly fix these issues?
And if I do use Odin to flash stock my warranty should remain?
Sorry for the long winded post, and thanks in advance for any advice given

Why is t210 so many issue? seriously!?
If one thing i need to clarify that doing any custom modification on the device will spoil your warranty. However if you did firmware stuff from kies will not remove your warranty. I would choose to flash into new firmware by using odin. But if your case you can do a factory reset then followed by kies and see if it is working. If it is not, download stock firmware from the net and flash it with odin.

thanks @Jacker31 for the response, i know about voiding warranty there is no custom software on it YET lol, only just got it out of the box, i am new to Samsung devices so i will do some research into kies, just don't want to void my warranty trying to sort it out.

I don't know if it's the same problem with my wife's tab t210. when you turn on the wifi it connects but around many seconds, the wifi icon is gone. and in settings the wifi freeze. i've done rebooting, restore factory settings but it didn't fix the problem. but when i try it to connect via my phone tethering it connects and the wifi icon stays. i check the tethering settings it was put on wpa2, but on my router it was just on wpa. So i change it to wpa2 and the problem on my wife's tab is gone.

Hi guys, so I installed kies3 but when I click the firmware upgrade button I get this message 'SM-T210' dose not support initializing. even though i had USB debugging selected. I also tried while the device was unplugged by entering the model and serial numbers but got the same response.
If I flash a stock firmware by Odin will the device log it on the flash counter? as it came with a 12 month warranty and i will send it back if i cannot fix it myself.

You should send it back because of the warranty, anything could happen (I meant for the warranty) if we do something.

[Q] OTA Weirdness - Tab Pro 10.1

Got a notice of an OTA last night. Figured it was for Lollipop so told it to proceed. Once the tablet rebooted the WiFi radio was disabled. Looked in settings which showed that WiFi was on, but no radio. Went online an saw that Samsung hasn't sent out the Lollipop update for the 10.1.
Question 1 - how do I restore my tablet since I can't get WiFi turned on?
Question 2 - where did this weird OTA come from?
Thanks for any help you can give.

Others having same issue
Thought I'd post this as info. Checked over at Android Central and several people appear to be having the same issue. Looks like bad firmware from Samsung. Bad build number is: KOT49H.T520UEUAOD1. Wiping and factory refresh may help temporarily, but eventually the wifi radio will be disabled. I'm going to wait for Samsung to get their act together and flash a fresh build when it's released.
Thanks for the help.

My 10.1 Tab Pro was updated too but wifi is working fine. I'm not rooted though. Same build number that you mentioned.

Wifi Issue as well
I had the same update come across last night and now I can't connect to wi-fi to save my life. Really pissed off. Done 2 factory resets already, reset my modem at home, turns out it happens everywhere and not just at home. Wifi says it's on but doesn't pick up any networks in my area and won't connect to the 1 that is already known on my tab. PLEASE HELP

Got the update last week. Wifi is fine but now daily I get a random reboot. Never had any problems before. Thanks Sammy!

I have the same issue with the build described.
Does one know how to correct this firmware update if the tablet is unable to connect to the internet?

You can download an earlier firmware from sammobile.com. If you are in the US, use the firmware for cellular South and make sure it's a 4.4.2 that you are downloading. After you download it, you can flash it with Odin. There are several threads here on xda that describe this process. If you still need further help, post again.

TabPro 10.1 SM-T520, v4.4.2 Build KOT49H.T520UEUAOD1 No wifi after update
Boy am I glad to find you guys with the same problem as I have. Couple of days ago I saw an update message and decited to go for it. Well, as all of you know, wifi stops working. Factory resets gets it working again but once everything is restored it stops working again! This is quite frustrating and I hope Samsung is working on a fix right now. I haven't been on XDA for a while and only rooted phones before. So how is the rooting/mod scene for tablets. Any good Custom Roms out there we can use until/when this is resolved? I'm good with directions and done some custom roms on my phones before. Let me know what's the good ROMS out there are...the bloatfree version is a welcome even without KNOX, I don't really use it.

Thanks for your feedback.
I had to use the firmware from November 2014 to get it to work and restore my wi-fi.
Again thanks

KOT49H.T520UEUAOD1 is the problem
Well I figure this particular firmware has a problem. Because even after factory reset, wifi works once and goes back to not working. So the best solution is to get an earlier version. I went back to Sep 15, 2014 version and it works well. Took forever to download from sammobile though. So if you need to flash to a previous version that works. I have post a link to the firmware I have on my OneDrive that got it working again, hopefully it will be faster for you to get your tablet working again. Here is a link. This is for the US Tab Pro 10.1 SM-T520.

thank you for those who warned about the wifi problems this OTA introduced. I'm just going to keep ignoring the tablets request to update. I thought i got a great deal on this tablet when i got a refurbished one for under $300 several months ago... but samsungs lack of support for this tablet is astonishing.

Flash latest factory images

Hey, did that, flashed all the factory images.

I just bought a used phone on eBay for a friend of mine, and he's having the same issues. Every time he tries to connect, the phone detects WiFi but doesn't connect. I had him reset his modem and router, and still nothing. He did factory settings on his phone as well, and still nothing. I had him find free WiFi at a restaurant and try that route, and he's still having issues. Will flashing new updates fix this issue, or is there something else needed in order to fix this solution?
I guess I can always have him send me his phone since he's not tech savvy! Any help would be appreciated.
Thanks

Have you tried the N Beta? https://www.google.com/android/beta
Shouldn't make a difference, but nothing really to lose by trying it. Other than there's a data wipe if you go back to stock. When I turned it off because some apps didn't work, it installed an OTA version in one shot with the latest version up to that point. With the data wipe. No security updates needed on top. That shouldn't make a difference either, but maybe it will.

SM-T805 WiFi and Bluetooth won't switch on

My neighbour has handed me her Samsung Galaxy Tab S model SM-T805 as she is unable to get the WiFi/Bluetooth enabled. It can be toggled to on but it remains grey. It appears to be up to date with Android 6.0.1
I have searched a lot for the solution and most suggestions have been to factory reset it. But after having done so, Samsung setup is still unable to enable WiFi. I went one step further by doing a factory reset/wipe data from Recovery but no dice.
What's the next step at this point?
edit: I also ran Device Initialization in Samsung's Smart Switch PC software to download and fully reset the tablet. Same issue still persists. Must be broken wifi hardware?

Downgrade the firmware first before condemning the hardware
Downgrade to lollipop.
It seems strange, but this can fix firmware errors causing these issues.
If it works after a downgrade it can then be updated as normal.

I don't know what Galaxy Tab S type it is to choose the correct firmware, there are many like SM-T805C, SM-T805K

I suggest updato.com.
If it's just the international T805 model then just download the one for that.
