[Q] Help! Bricked AT&T Galaxy S3 1747

Help! I rooted my Galaxy S3 about 3 months ago. I wanted to return it to stock without root so I could use the stock recovery and receive the new 4.4 OTA. I found a file online off a YouTube video that I thought was for my phone. I flashed it using mobile ODIN and when it powered back up, I had no mobile network and could not make or receive calls. I tried another file I downloaded and I installed from zip when I was in receovery and now the phone will not power up and does not have the light on when its connected to a charger. It seems to be dead.
I installed from zip because it kept failing when I tried to use ODIN on my computer.
How do I fix? Can it be fixed? I don't know anything about all the technical stuff such as modems, kernels, etc. I should have left it alone!
Any suggestions?
It's an AT&T Galaxy S3 SGH-1747

8.4 Tab S Forgets WiFi Networks On Reboot

I'm on stock, rooted odex. I believe the issue happened after I rooted. On boot, it forgets all previously connected WiFi networks. The only mods I've flashed was the 4-way boot (which didn't work since I have CWM and not TWRP). I've tried deleting the dhcp files in the dhcp folder and the wpa files in the etc/wifi folder. Neither worked.
Anyone else having this issue?
Edit: Factory wipe didn't rectify the issue. Guess I'll ODIN back to stock. Hopefully this is a hardware issue.

Strange.....mine works fine, rebooted numerous times.

Figured out the issue. I mistakenly flashed the T800 autoroot instead of the T700 autoroot.

Hi
I am stepping in on this thread, because I encounter this issue.
I just rooted by Galaxy Tab S 8.4 (LTE) - T705 and I followed this site http://theunlockr.com/2014/08/09/how-to-root-the-samsung-galaxy-tab-s-8-4-lte/, used as instructed CF_AutoRoot_Port_T700_BeansTown106.tar with Odin3 v1.85 .
- when rebooted the wifi forgets the password, (as long as you dont reboot the wifi is okay, and i can connect to other network and connect back to the original wifi.)
Do anybody knows how to fix this issue?

I think you have to change some sort of file to something to make it remeber it. I cant remeber what the fix was but it was somewhere in the cfautoroot fourm.

HI,
Consider also using Skyhigh Kernel, it fixes your issue.

My nonrooted Tab S forgets WiFi on reboot and when I switch WiFi off and then on.
I found that this probably is a KitKat bug (http://forum.xda-developers.com/showthread.php?t=2685519)

If you are rooted then this is what fixed it for me.

Unfortunately I have no root, so I flashed the newest firmware (T705XXU1ANH1 – XEH from France) and it fixed Wi-Fi

So, I using mine tab with and 6 on the latest image from Brazil.
It is rooted and with TWRP.
It doesn't save wifi networks. If I turn wifi on and of it looses everything.
Just to be clear, it had this problem before I installed TWRP. It took me quite some time to notice the problem so I don't know if it is related with the root method.
I even flashed a custom kernel, but still no luck.
Does any one know of a solution for this issue on Android 6? Stok?
Thanks

try to flash a diffedent rom. i personally never had this issue but maybe a new rom may help.

[Q] No Wi-Fi after TWRP restore??

I'll try to boil this down as much as possible... Bought a used M919 on Craigslist, it was an original MDL 4.2.2 build. I rooted, loaded Fenny's 4.4.2 ROM, had it all going great, then it got blacklisted for unpaid device balance...
Just bought a refurb direct from T-Mo, of course it's NB4 4.4.2. I did TowelRoot, installed current TWRP, restored Data & System, got stuck at the T-Mobile animation screen (so long the phone was getting hot). Flashed back to Fenny's fixed original 4.4.2 ROM, it booted fine, had Wi-Fi & LTE signal, did TowelRoot, installed TWRP again, restored ONLY Data...
Phone boots & runs fine, makes/receives calls & SMS/MMS but I have no Wi-Fi (won't successfully turn on). Also, I'm constantly getting a "Security Notice" saying "Unauthorized actions have been detected. Restart your phone to undo any unauthorized changes."
What gives? I've tried re-flashing the separate modem files, but it doesn't help.
Ideas please?

Did you flash the WiFi fix in Fenny's thread? Have you tried a different kernel?

Must've missed the Wi-Fi fix somehow. Thought there were only problems when the MDL bootloader was maintained.
Yes, I'm running Fenny's kernel, 1.2 or 1.3.

BINGO! Wow, makes me feel like a total noob. Haven't seen the Security notice yet either.

I did a search for "Unauthorized actions have been detected" and it pulled up a couple pages for other Samsung devices. You could try doing what they all say to do; I would assume that because I've read the same solution in both the S5 forum and the Note II forum it should work for all Samsung devices... anyway, open up SuperSU and somewhere in the app there should be an option to disable KNOX. That should get rid of that warning.

Wifi won't turn on

Hi guys. So about 1 week ago I finally let my s4 mini I9195 Do the update its been wantng to do for a while. Turns out when the update completed and the phone was turned back on again I couldnt connect to wifi, just press the toggle and it does nothing. So ive been lurking the web for solutions and done around these:
-Taking battery out various times and in diferent situations
-http://forum.xda-developers.com/showthread.php?t=2364980 did that even though I have no idea what rooting is and such though Ive read about it 1000x , just dont get why you do that or why there are so many ways and such
- wiped cache/ returned to manufacturer settings also a few times
So, by this point I have really no idea how to fix this guys and its been a pain because I am in erasmus and could really use the wifi. I really apreciate your time for reading this thread and hope that you are able to help. Awaiting your sugestions
Thanks

What you're describing is a very typical issue: the firmware wasn't updated completely (e. g. modem not updated). Solution: flash the firmware again with Odin.

Hey man, thanks for the reply. Can you give me a little more info on how to do that procedure?

Search for Odin (v3.09 or so). Check your firmware version and download it at Sammobile.com.
And use the search for further information.

Hey man thanks again for the reply.
I was doing this http://forum.xda-developers.com/galaxy-s4-mini/help/to-stock-firmware-choosing-problem-t2968295 but near the end it fails for some reason... any idea why?
So I tried it again and this just happened.. Kies wont even recognize.
http://imgur.com/a57W9KM

If you are already on Kitkat you need Kies 3.
Have you probably tried to flash an JB firmware?
Search at Sammobile for the latest firmware for your country and network provider and flash it with Odin.

Hi guys,
i have a similar problem. I flash many time a couple of ROM (CM11 - slimkat) but the wifi doesn't turn on and also the cellular network and the bluetooth don't work...
In the last days i had many problem with my phone because i make a mistake during the flash (on odin) of a stock rom.
Do you have any suggestion?
Thanks a lot

I had the same problem. Wi-Fi didn't work after uploading KK firmware for my country (while to my surprise KK firmware for Belgium worked ok). I tried 3 times to upload KK firmware (XEO, anr PLS) via Odin 3.09 with the same effect (no way to turn on Wi-Fi). Then I used Odin 3.06 and it worked for me (I was able to turn on Wi-Fi without any problem - strange but it had worked). So try to use older ver. of Odin first.

[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!

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.
