[Q] Galaxy Tab 7.0 Plus - Wi-Fi no longer working

I have a rooted GT-P6210 that was working perfectly fine and last night I updated Busy Box Free from Google Play. Busy Box Free reported an error with the install and shortly after I noticed that my Wi-Fi would no longer connect. It just reports "Error" after trying to connect to Wi-Fi.
I tried re-rooting my device but that didn't fix my Wi-Fi issues. I researched everywhere I could think of to unroot my device but all the threads seem to refer to guides that I don't see and firmware links that no longer work. I managed to find a copy of Odin3-v3.04 but I still don't have instructions on how to do it nor do I have the firmware that I need.
I decided I would try going back to factory settings by powering off the device and booting into system recovery. I have done a wipe data/factory reset multiple times but Wi-Fi still doesn't work and I don't even know if that removed the root job I did.
When I plug my device into my PC and run Samsung Kies it reports that I have the latest firmware PDA:LA3 / CSC:LA3 (XAR)
So I am stuck and not sure what to do at this point. I have a pretty useless device that won't connect to Wi-Fi. I don't know if I wait around for ICS and install that if it will fix my problem.
Is there anyone that could help me restore my device to factory settings with actual guides, and provide working links to the firmware I would need?
Thanks for your help,
Bryson

You are in the wrong forum.
This is Galaxy Tab 7" not plus.
Might be better asking at the right place

Networks detected but will not register

So I had some escapades today, I had my SGS running jellybean, then I tried to change the screen density and bang, bootloop. I panicked and after some odin fiddling managed to get it booting Darky using odin. I was in a room with no signal at the time so I thought nothing of not having any signal, even so I then went ahead and used recovery to reinstall my Jellybean rom since that's a bit nicer than the 2.3 Darky.
Long and the short of it is, I can search for networks in my options and it will find them, but when I tell it to connect to one it says "Can't connect to this network right now. Try again later"
I have tried later and surprise surprise it didn't work. I have tried installing a different radio, clearing the dvalik cache and fixing permissions as well as a few other things. Please can anyone suggest something, this seems to be a very uncommon scenario and it's stressing me out that I can't find any solutions.

Yeah I've checked them and unfortunately they all seem to be in order still, though there are a lot more settings than any website offers things to put in them

same problem
i am having this same problem on all cyanogenmod 7,9,10. i have tried many radio and modem flashes. i can scan and see networks, but i can never connect to them.
have you made any progress?

Problem is EFS folder which tends to do with IMEI.
To fix it you need to copy the backup EFS folder from your SDCARD to the root of your device. (/)
If you don't have a backup you'll have to ODIN back to stock and re-root....etcetera

thx
thank you for the response. I put it back to stock lastnight before bed so i will give this a try.
i have the gti9000m from bell in canada. I updated it through kies to 2.3.3 gingerbread and it all went badly. It would boot up and load to the os be on for a bit then reset. It turned out to be wifi problem, running it on airplane mode stopped it from rebooting. Then if i tried to turn on wifi it would quickly reboot.
So then i tired all the cyanogenmods, which worked it stopped rebooting all the time. however the wifi would connect and work for about a minute then it would drop. doing the
1.turnOn gps
2.turnOn wifi
3. turnOff gps
this would let the wifi work again for about a minute. I tried all the wifi fixer apk, and a bunch of wifi.zip mods, and then ping the router gateway constantly, none solved this problem. Very annoying because i need the wifi working for develpoment of apps. I have spent a great many hours on this problem. lots of people seam to have this problem but no solutions have wokred for me.
So, my questions are....
1. does your wifi work?
2. how the heck do i get mine to work?

back to stock
After going back to stock then upgrading connecting to network operators is fine.
wifi is still broken though

[Q] WiFi problem with MIUI

Hello,
I have just flashed MIUI Gingerbread 2.4.20-RC3 to my GT-S5570, everything looks great, except WiFi, when I turn on WiFi, it says "Scanning" finds my WiFi and then "disconnected" and again shows "Scanning" for 1 sec and again "disconnected", what can I do?

WiFi Error
You need to revert to your old stock rom, because the drivers for WiFi aren't working. Same thing happened on my mobile phone, when I flashed it with the newer firmware. Didn't really find the solution to this problem, but solved it by going back to my old rom. Hope this helps.
You can also try typing this code into your phone: #*#*526#*#*
It might work for you.
Best of luck.

Thank you for reply.
It is working now, here is what I did: In phone settings I tried to change themes lock screen to other, but unfortunately not default lock screen was way too big (very big resolution) so I was not able to unlock my phone any more, once I found that I can do it pressing back+volume down, it helped to unlock, but MIUI was crashed and stopped working, so I had to wipe all data and cash, to reset default settings, after this, everything works great now.

the same thing was happening to me (on the same rom)>> "fixed" it by reseting the notebook-hot-spot (connectify) I use
[sometimes even a simple wi-fi turn on/off or rebooting the device would help too]
I'm posting this in order to prevent you from doing more drastic stuff :cyclops:
hope it' helps

[HELP] Wi-Fi problem after mm update- SM_9208

My note 5 is the duos version, imported in Romania from Taiwan (SM_9208) After updating to Marshmallow yesterday, everything worked fine except for on thing: it doesn't find my Wi-Fi network from home anymore and the only way I can connect to it is by going to,, add network " and manually inserting the ssid and PASSWORD because it doesn't appear on the available networks list. Thst means that every time I turn my wireless off and then on, I have to repeat that process.
I haven't had the chance to try any other WiFi network, but I tried with other phones to connect to the network and they found it and connected to it without any problem. Furthermore, any third party app like WiFi analyser is able to see the network.
Do you guys have any idea how I could possibly solve this?
Thank you and have a wonderful day!

Try to backup your phone and then do a factory reset.

I factory reset after update OTA and everything work perfect.

uhm... does n9208 has update for MM already? if you have links kindly share tnx in advance

I tried doing the factory reset and it still has that problem.
And I did receive the update yesterday through OTA.
Other suggestions? Thank you, guys!

First, try clearing the cache again. If it still does not work, the update may have downloaded improperly so some file are corrupted. It will continue to use the same corrupted files even if you reset. Have your tried flashing the stock Taiwan Rom using Odin?

//LATER EDIT: I finally made it work by simply changing the wireless network's name. For some reason, my phone wouldn't find the network with its default name.

supersu pro latest update killed my radio, now bricked.

Today I received a notification from supersu pro that I needed an update. After it installed it requested a restart. After restart, there was no connection to cell service nor could I turn the radio on in network settings nor were there any settings registered. I was however able to connect using WiFi from my home computer. I was running stock rom with twrp-recovery and OS h81120o for t-mobile. I tried restoring backups by twrp with no radio/network function. I installed
twrp-3.0.2-0-h811.img
android_device_lge_h811-android-5.1.zip
G4-H811-MM-20i-Stock-Debloated-Rooted.zip
G4-H811-MM-20o-Stock-Debloated-Rooted.zip
G4-H811-MM-20o-Stock-Rooted in this order with nothing different working in network connection and radio off. I finally installed LG-H81120i-Flashable.COMPLETE.zip and it said installed successful yet when restarted the phone bricked. No power on, nothing. I received than same notice for my rooted Samsung galaxy tab 4 8.1 and declined it and am still running fine there. Any thoughts?

Hey,
I was in the exact same boat and almost gave up!
Got my LG back from repair and I rooted it then made a back up, everything was working fine. Flashed a new ROM and updated SuperSU, was not able to get a signal or mobile connection after that. IMEI Number was now NULL. I tried factory reset but still nothing can get the network signal back. Even restoring back to my back up did not work.
I read that if you flashed the LG-H81120i-Flashable.COMPLETE.zip you will brick so I avoided that. I finally found the solution and maybe this will work for you.
Download LG UP and your kdz file (H81120o_00_0613.kdz was mine) on your pc.
Set phone into Download mode by pressing volume up and connect to PC.
Open LG UP and load the KDZ path file and run. Phone should reboot and come back. My signal came back after this.
I hope this method works for you.
Best of luck!
