Wi-Fi and Bluetooth unknwon on GT P1000

Hi
My Galaxy Tab P10000 doesn't recognize the MAC Adr of Wi-Fi and Bluetooth.
I can't use it. I can use only3G to access the internet.
This is my Tab Conf:
Firmware: 2.3.3
Base Band: P1000XXJPZ
V. Kernel : 2.6.35.7 [email protected] #2
Build No. : GINGERBREADAD.XXJQ1
PDA: P1000XXJQ1
PHONE: P1000XXJQ1
CSC: P1000XAJQ1
Any idea about this problem and how to solve it?
I hope that someone help me.
Thanks
Don't want to state the obvious but are they turned on in settings?
Is your device rooted or all stock?

Hi alexgogan
When I turn on the wi-fi, after a few minutes appears the message ERROR and I can't connect or detect any wi-fi network. When I turn on the bluetooth, after some time he turn to the first step.
In the info Tab, the Wi-Fi and the Bluetooth mac address is unknow and the state is unavailable.
I've installed a stock rom (this rom) with the Odin. But this problem is prior to this installation.
Please help me. Thanks.
Sounds like there is modem failure. You may need to flash new modem again.
Would suggest reflashing stock rebooting and trying again.
If it was like this prior to flashing this build that may be the problem with original install.
How long has wifi not been working?
Thank you for your feedback.
The wifi stopped working after an upgrade via Kies, in November. Later I discovered that the bluetooth does not work too.
After that I made some ROM updates, but without success until today.
My questions to your sugestions are:
this modem (in my Tab) is in the correct version?
How can I flash the new modem?
which version?
by Odin?
Sorry for not getting back to you.
But if it's a mess with kies its strange.. But would not be surprised though if you got fault device with wrong stock and the official flashing messed things up.. So depends how long you had it, if it's still under warranty then Sammy must fix it, but not unless it's been rooted and the will use any excuse to get out of fixing it.
But odin will have no probs with chains cf root as well.
Just wish knew what it was before the flashing. I cause you might have changed things in the process. The it will depend on your carrier as well so www.samfimware.co will tell you and this wiki one of the guys put up should also help... But lot depends on your device for which carrier as some radios are modified and if you have wrong one then that would explain a lot.

That or your actual physical radio is bust as well so then is hardware and no flashing will fix.

[Q] Problem with s4 wifi

I recently restored stock rom on my Samsung galaxy s4 GT-i9505 from cm11. After that, the wifi just will not turn on at all. I will get a notice when i try to turn it on. I cannot upload a screenshot of the notice i get, it says "Security notice Your device's security has blocked an action that is not permitted. No further action is required."
Please help me solve this issue if it is possible. I really hope i have not screwed up my phone :crying: Any form of help will be greatly appreciated.
Edit: I got it to work already. i guess i flashed the wrong rom on my phone. i would like to thank @samersh72 's guide and link to stock roms that helped me solve my problem
Would love to know what firmware you used, no matter what I do it does not work, have flashed multiple roms.
I removed knox and it took some of the wifi with it on I9505XXUFNB9, I can reconnect to wireless networks but the passwords wont hold. On newer roms it just doesnt work even without a rooted kernel.
Edit: Got it working too, although cf-root to thank.Phew.

[Q] Help Needed!

First of all i would like to tell you that i am a newbie
I rooted my Samsung Galaxy S 4 (SGH-i337) Having info as follows --
Firmware Version : 4.3
Baseband Version: I337UCUFNB1
Kernel Version: 3.4.0- 1921628 [email protected] #1
Build Number: JSS15J.I337UCUEMK2
Now after rooting my wifi is not working when I switch it on its shows error and turn back off. If someone could please help me get my wifi back without unrooting or bricking my device I would really appreciate it. Please remember I am a newbie please talk English. I found tons of ways to solve the Wi-Fi problem but cannot find the PDA file to flash using Odin if anyone could find that file for me for my specific phone I would be more than happy or if anyone has an easier method to get the Wi=Fi working again please let me know thanks!

The root methods you have listed are intended for older versions. The only functioning NC1 root method is towelroot. Please check the all things NC1 thread prior to posting. All info can be found there. The person above has given the link to towelroot. If you go to the galaxy s5 forums, you can get a tutorial on it, but it's pretty straightforward. Enjoy your rooted device.
Remember that the phone has a locked boot loader. So, the stock kernel and recovery cannot be replaced. The only working recovery is safestrap. There is also restrictions on the Roms that can be flashed.

do you have a stock rom, are you root?
WIFI is kernel controlled , if you are root and have a custom recovery and have a custom rom you could try a different kernel ....
If in stock, flash again stock rom , maybe something went wrong during OTA

My wifi was also off Until I found roms and fix from XDA
Now GT-I9505 is working great

Thank you for your time.
I don't actually have any idea about flashing or updating. All I know is that my S4 was okay until my nephew updated it to Kitkat. First I noticed that the mobile data is not working. I ignored it because I always use WIFI, then I also noticed my bluetooth isn't working as well. And recently the WIFI gave up too.
My nephew tried what he could like rooting, flashing kernel I think, modem wifi fix and custom ROM but nothing resolved the problems.
When I press mobile data, it turns green but there's no signal indicator,but if I put on another sim from another carrier (I'm in the Philippines by the way) mobile data turns on as I see signal on the upper right part of the screen.
But no matter what sim card or what carrier I'm on, the WIFI and bluetooth do not turn on. It also shows bluetooth and IP address unavailable.
Do you think this can still be fixed or is a hardware issue?
Thank you.

That's exactly what I'm downloading right now. I'm sorry I don't know what towelroot is. I like the S5 ROM, can I put it back after this procedure?
I'll let you know if it works.
Thank you so much!

Yes you can , but you have to start all over..root , custom recovery and then flash custom rom , towelroot is used to get root with out tripping knox warranty bit....but if you are going to flash a custom rom the bit is going to be tripped anyway if it was not already.
This is just depressing.
I downloaded the file twice but when I'm already unzipping it it says folder is empty. I tried to download it on my tablet as well but it always fails.
I don't know what else to try. If only I can just go back to jelly bean.
Thank you for your time anyway. Thanks a lot.

I am currently doing what you suggested but it's not moving anymore. I have been waiting for almost an hour now.
Here's what I can see.
It stopped on:
<ID:0/004> system. I'm. ext4
I'm scared to unplug it because my phone might not turn on again but it's not doing anything anymore!
What should I do?

Hi, I was able to complete the firmware update to XXUFNBE but its the same thing, no mobile data, no bluetooth and no wifi.
I put it back to XXUNGH8, same thing. I don't know what to do anymore. Is this a dead end for me?
Hi, I am having the same problem. For some reason I can't type *#1234* in the dialer (I can, but it doesnt do anything). My wifi stopped working a long time ago when I received official OTA to kitkat. I've tried flashing different kernels and roms, but no success. I tried flashing WiFi fix from the other thread, but it didnt work. BT and sound are fine.
ROM: 11-20141024-NIGHTLY-jflte
Baseband version I9505XXUFNC9
Kernel version 3.4.104-cyanogenmod-g52b4b50
I was thinking about flashing bootloader and modem+non-hlos XXUGNH8 from http://forum.xda-developers.com/showpost.php?p=50965837&postcount=2627 - might this help?
Hi..im maybe late but my i9505XXSHQB1 5.0.1 Also have wifi and thetering problem..how cam i fix it
