[Q] Messed up my Tab S 10.5, no wifi cant flash stock firmware

Not sure where and what I have done wrong.
I wanted to root my Tab S 10.5 (SM-T800), so used Odin v3.07 also tried with 3.10.6 using CF-Auto-Root-chagallwifi-chagallwifixx-smt800.tar and also tried CF_AutoRoot_Port_T800_BeansTown106.tar but rendered my WiFi useless, it just constantly scans, says saved secured, lit in blue signal, tried 2G and 5G, no luck.
Next I tried to put back to stock firmware T800XXU1ANF8_T800XAR1ANF6_HOME.tar but gets so far then just fails.
It is a new UK Samnsung Galaxy Tab S 10.5 UK.
I am novice so please be gentle regarding tech talk lol.
SuperSU v2.01 Chainfire Installed fine
I would prefer rooted with wifi, failing that i want to go back to stock
Any help appreciated

[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.
Sent from my SM-T520 using XDA Premium HD app

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.

Official 5.1.1 for T-Mobile (607t) issues

So I've having a bit of an issue with my 607t and I recall seeing some of the issues before. I was rooted before and on a custom 5.1.1 for a 605. Everything worked except it would sometimes boot back to recovery after power down. (known issue)
So today I went ahead and downloaded the official 5.1.1 and used Odin to flash back to stock. I'm not having any OS issues but am having a problem with wi-fi and the LTE radio. Wondering if anyone else has seen this and what was your fix?
1) The wi-fi will not remember passwords after a reboot.
2) After the update the unit is telling me that no SIM card is installed. Verified SIM is good on another device and tried a different SIM in the Note with same results.
Have flashed via ODIN again, factory reset a few times, remove/install SIM and the problems persist. I'm thinking there must be something from the 605 kernel that the ODIN flash isn't fixing.
Would appreciate any tips. - Thanks!!!!

You have to update the bootloader. There's a check-box in Odin for that.

That was the ONE thing I didn't do. And it worked.
That box was always greyed out when I loaded the file and didn't notice after the file processed that it was an available option.
Thanks!!!!

WiFi will not turn on...

Hi. I have a Sprint Samsung Note 4. I was getting a screen overlay error and decided now would be the time to change the ROM on the Note.
I followed the steps from "How to Install CyanogenMod on the Samsung Galaxy Note 4 Sprint ("trltespr")"
After I installed the first ROM, which was the latest nightly, and booted it up, I noticed that the WIFI says "Turning on" but doesn't ever turn on. It's greyed out in settings as well. I tried a few different nightly's thinking it was a defective file or bad install. Still no fix.
So then I went http://www.grantbarker.com/samsung-galaxy-note-4.html to try different roms, and I get the exact same issue.
Now I'm thinking that there is something I'm missing that the original ROM had. And for some reason the backup I made from it is missing, so I can't go back to it either. Is there a way to fix the wifi? It kind of sucks without it. Thanks for any advice that could help.

Were you on Marshmallow or Lollipop stock? Sounds like you have the wrong bootloader and that may be the reason. You would either have to flash the recommended stock tar or bootloader or bootloader and baseband.
I don't keep up with CM but the thing to check for is recommended bootloader in OP or search the thread. You may find it necessary to flash OK1 or OG5 bootloader. Dunno, maybe check for the baseband too for CM.
There's a bootloader and baseband thread in the development forum for Sprint Note 4. You should find what you need to flash in Odin AP mode. The ones labeled firmware are bootloaders.

You could probably try reverting to the factory settings and checking if the WiFi works? And then, you could change it to the current ROM again. This might help you resolve the WiFi issue.

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'll just get a lollipop build from sammobile?
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.
