[Q] Problem with s4 wifi - Galaxy S 4 Q&A, Help & Troubleshooting

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.

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.

Slow Internet (3G/LTE) after 4.4.2 Update

Hello Guys
Well, let me get straight to the point. After my old rom (Revolution HD3) was draining my battery pretty fast, i decided to update to 4.4.2. Well, i downloaded the latest 4.4.2 for switzerland from sammobile.com. I flashed it and it somehow was all laggy and i had fc's the whole time. After some time i was able to use the phone anyway, but it was laggy. And the problem was that my 3G connection was EXTREMELY slow. I got connection time outs the whole time and wasnt able to download anything. Well, i thought it was the rom i flashed trough odin, so i downgraded to 4.2.2, my original rom, and updated trough KIES. The rom wasnt laggy anymore, but the 3g/4g was slow. I tried different Modems and Kernels. Nothing Helped. I then decided im going back to a custom rom but the flash failed. Then i tried another rom and it failed again. So i thought it may was cause i was on 4.4.2 and tried to flash a custom rom that was 4.2.2. I then tried to reflash my stock rom trough odin, and it FAILED. And that's how i bricked my phone. I can still enter Download Mode, but can't enter the recovery anymore. What do i do? I'd like to solve both problems.
Thanks guys
Btw: I've got an I9505
I assume you didn't wipe anything before you flashed stuff? Thats like rule number 1 to do.
You can try flashing a recovery true Odin.
Hej Guys
Um.. Just to let you guys know, it is possible to downgrad to 4.2.2 from 4.4.2. I just did it this morning and had sucess. But the problem with the really slow internet connction still is here, when im on a 4.4.2. And, it is the same with custom roms running 4.4.2. I tried different kernels and modems, nothing helped so far. As soon as i was back to 4.2.2 it had the usual connection speed. I called my provider and also called samsung itself. Obviously, they both told me to bring the phone back for garantuee. But well, as i know it's a software problem and not hardware, i wont do that. So can you guys help me? What should i do next? Actually im back on 4.2.2. Thanks
Edit: Oh, and ofc, i did everything like wiping/factory resetting, wipping preoload etc. It's not my first time flashing.
It's not possible to downgrade from 4.4.2 to 4.2.2! End of..

Are you serious dude? Im running 4.2.2 right now. What is your point?`I didnt even ask about it. I asked about a solution to the problem that i get slow 3G/4G on my I9505 when running 4.4.2. If you want a proof Pic about it running 4.2.2, i can give you one. But i dont really get what your point is.
Hang on hang on hang on, it is common knowledge that you cannot downgrade from official samsung 4.4.2 to official samsung 4.2.2 because in odin you will get failure at aboot.bin because you cannot downgrade bootloader.
How ever what would be really good is instead of just trying to say it then jumping out saying what's your point, we'll my friend the point is, it would be advantageous to everyone in the entire samsung galaxy s4 i9505 community if you can tell everyone how you did it.
My perspective is your doing a bit of flaming.
Pictures really won't prove a whole lot as anyone can do some build.prop edits and show different rom name and version.

Well, if it sounded like flame to you, it wasnt. I didnt create this thread to flame others. But i wasnt kidding saying that i downgraded to 4.2.2. Here how i did it:
Was running 4.4.2 (I9505XXUFNB9)
Flashed TWRP recovery.
Flashed custom Rom 4.2.2, which FAILED!
Flashed Official 4.2.2 trough odin, which FAILED!
Flashed TWRP recovery again, since it was somehow damaged from the flash before
Flashed Wanamlite 4.4.2
Flashed Custom Rom 4.2.2
Flashed Official 4.2.2 with succes.
Im not sure what part of those flashes were essential, but i have no reason for liying to you. What would be the perks if i did?
But now again BTT, Did anyone else have that problem of slow interenet connection? Or is it just me? Maybe some ideas?
Regarding slow Internet maybe it's your carrier with issues.
Maybe the downgrade back to 4.2.2 has created issues in its self. Have you checked your baseband matches bootloader and build?
A problem we have is we can't see the version of the 4G modem (non-hols) so that might be also an issue.
When you flashed back did you do a factory reset?
In regards to downgrade do you still have the Knox bootloader?

Well, i called my operator and the girl on the phone said that some people already called with the same issue, but its not on their side. It's a problem with the update samsung released. After the downgrade i had my Knox Bootloader and everything worked like it always did.
Yesterday Sammobile released a new ''rom'' for my country. Downloaded it, flashed it and it works great now. I have a bit of a fast battery Drain, but the problem with the slow internet seems to be fixed.
Again: 4.2.2 worked perfectly after downgrade. It had no issue, No FC nothing at all. Maybe i was lucky? No idea, but im happy my 4.4.2 works now
Thanks anyway for your help guys
Edit: Yeah, my bootloader matched both baseband and build.

If you had done your homework, you would know that in almost all cases Samsung repairs it even with Knox set to 0x1. They even publicly stated it in the Netherlands that they will repair your phone even with custom roms.
And you don't know the law in Switserland. Nor do I. So you can't say that in Switserland his rights are voided by flashing.
If Samsung doesn't give you the warranty, then you still have your consumer rights in the European Union (not that Switerland is in it). No flashing, modding or other chances decleine you your rights if it's not related to a hardware failure. In the countries that you and I live in, it will never void your rights if the damage is not related to flashing or modding.
So well, i think that in switzerland they actually WONT repair it if you flash it, but i aint sure about that, since i never had to send it to repair. But anyway, it was only a software problem on their side. They released another version for switzerland and it seemed to have fixed the problem. I have a bit more of a battery drain, but i actually think im just too used to some other custom roms. Anyways, thanks for the help guys

[Q] Wifi problem

Hi,
If you can help me fix this I'll pay you.
I have rooted my i9505 using Towelroot.
The stock installed Android version was 4.4.2, the baseband version was XXUGNG8.
I have installed the philz_touch_6.58.0 recovery and tried several ROMs.
All ROMs install without problems but I can never turn on Wifi or it turns off after 10 seconds.
I have tried various kernels, modems and bootloaders.
I would like to be able to try different ROMs but prefer to have a clean 4.4.4 ROM.
If someone can help me solve the Wifi problem I'm willing to pay for it.
If you can contact me on Skype (username: marcselman) I can follow all instructions immediately.
Thanks.
Still nothing
I have now reverted back to stock ROM XXUGNG8. But even now Wifi won't turn on.
My Knox counter has been tripped but I don't care about warranty. Could it be the reason Wifi is not working though?
My offer still stands though. If anyone can add me on Skype and help me fix this I'll pay you.
Marc
The things that tip off wifi is the modem and kernel. Have you search for hlos modem

[Q] i9505 problems

Hi
I've been trying to get to the bottom or this for months and months, no clue what to do.
Firstly, no matter what ROM i try, whether it be stock or not, sensors do not work AT ALL. I've tried about 10 ROMs, and no joy.
When i first had my phone, it was on stock 4.3 ROM, and rotation worked fine. after this i upgraded to 4.4.2 OTA and rotation still worked. As soon as i rooted my phone, all sensors died and now i cannot fix them. The phone also has a stupid amount of lag, especially when trying to answer a call. I tried then going back to stock 4.4.2, but the sensors remained broken
I have tried reinstalling Samsung HUB as i found in a few posts on the internet, but again this does nothing at all.
Can someone please please help, any ideas no matter how far-fetched are welcome,.
Thank you in advance.

Galaxy s5 issues after update

Hi everyone,
My brother has a samsung galaxy s5 SMG900F which was working just fine on lolipop. After seeing that he got updates to install I installed them all for him. After the update was done the phone behaves strange. It has signal but i can not make any calls, when i try it it just hangs on the calling screen with nothing happening.
We did also a factory reset but still the same issues.
The phone is now on: XXU1BOJ1, XXS1PPC8.
I do not know which version it was earlier but right now I am downloading G900FXXU1CPEM, G900FBHT1CPE3 from sammobile (latest for Bosniua BHMOBILE) and I hope that after flashing it the issues will be gone.
In the meantime, did anyone else experience similar issues? Why could this be happening and what is my best bet on solving it?
EDIT: I need also to mention that the wifi is going crazy, it can not connect, or it connects but disconnects again etc.
EDIT2: After flashing official stock 6.0.1 the problem still exist Please help
EDIT3: Just did a factory reset through the service menu, after that flashed again the 6.0.1 and now everything is working again
