[Q] Any Solution to Knox and No Wifi

I'm running stock 4.3 on the i9505 unlocked,
Knox is 0.1, so my wifi stops working if I switch the phone off or battery runs out,
Currently using the app "autostart no root" to block Knox at startup,
Wanted to know if there is any solution to fix the wifi issue without using the app,
Tried different modem and wifi fixes that went with them but non worked for me if I switch off and on,
restarts sometimes worked but other times didn't...

om22 said:
1. untick "Auto reboot" in odin
2. flash the stock rom again
3. reboot your phone to download mode again (by holding the power and vol down button for 10 sec)
4. flash the stock rom a second time with auto reboot ticked
This will fix your problem.

I have the same problem. I flashed a new Stock 4.3 today, and when the phone boots up I can not turn wifi on. I get a message about security and the process being blocked.
Tried to flash two time like above, but it will not work. How can I enable wifi again without installing av cusom rom?

Sorry no real fix,
You can root and block Knox completely this will give you wifi,
As I wanted it stock I drop it into a service center who have forwarded it to samsung now,
So long wait

Same here.. & did you flash a stock (unrooted) rom first before handing back to service center.. I thought if it was discovered to be 'rooted' they won't fix it as it voids the warrenty or something

Auto start app from the playstore works but some times doesn't,
Best way is too root and use titanium backup and freeze all Knox entries

but for 'freezing' you need the paid for version & without Wifi how am I suppose to get it off play store anyway. It cost's too much using GPRS on PAYG to download.
Would renaming the files (whatever they are called) & rebooting do something similar ??

If you do a rest does the wifi work on initial setup,
I have a unlocked phone and the German O2 rom would work with wifi,
But after a switch on and off wifi went

I assume you mean a hard reset ??
Didn't try at the time & I've ONLY just managed to get (most of) my apps restored - don't fancy resetting again to find out
I've sent email to Samsung support to see what they come up with..(They MUST know there's a problem with the firmware & they may come up with something)
If not, I might try flashing the ROM again through Odin (as mentioned in a post somewhere - apparently doing it a couple of times MIGHT fix it) - if not I MAY attempt a full Unroot

I faced this problem, when I updated my Knox 0x1 device with Kies (+ CF Autoroot and Triangle Away). After this, I was not able to turn wifi on. My solution was simple, I flashed my device with Odin, CF Autorooted and Triangle Away again, and no problems anymore. Wifi is working and everything else too.

My problem is that I am unable to even TURN IT ON. When I attempt - I get a silver shield pop up, & a 'Security notice' stating - 'your device's security has blocked an action that is not permitted. No further action is required' - App info tells me it 'Knox notification manager'
I've been emailing them..telling them KNOX is preventing me from turning on my WiFi - so far all they suggested is downloading KNOX, then Install & uninstall to fix this notification - but how can I if I don't have WiFi ?? - GPRS on PAYG is WAY too expensive Don't these people think ?!?!
Anyway just recently found out about this Knox 0x1 business & where to find it..(for the other newbies It's on the 'Download ' screen (Volume Down + Power + Home))
But I'm confused... On my phone there are 2 KNOX references
- Am I right in assuming you are referring to the 'KNOX Warrenty Void' being 0x1 & not the 'KNOX Kernel Lock' ??
Also (being a total Noob) I assume you download a suitable 4.3 STOCK rom (say for e.g. sammobiles) to use
Me - having a UK brand free Unlocked phone is currently downloading 'I9505XXUEMK8_I9505BTUEMK5_BTU.zip' from there based on this info I managed to find (Am I downloading the correct one ?? can some1 confirm this please - thanks ??)

& used this Unroot/Unbrick guide to revert back to a 'stock' rom (do you know if KNOX Warrenty changed from 0x1 to 0x0 when you did this ??)
Did your Wifi turn on ok after this ?? or only after you redid CFAutoRoot &/or Triangle away
I'm not to fussed 'going back to stock' JUST in case Samsung suggests I take my phone to one of their Service departments...I just want to get my WiFi to turn on
EDIT: FYI - I took the plunge & reflashed with the rom I mentioned above.. it didn't wipe my phone But the WiFi now works - I can turn it on and off.
I 'CFAutoRooted' & 'Triangle away' but NOT done any actual rooting (i.e host file editing etc) - so now I have a rooted phone...
Only thing is - If I try 'About device' > Software Update' > 'Update' to check - I get the usual 'This has been modified - no update available blah blah blah' message. I guess it's because of the 'About device' > 'Status'> 'Device Status' shows 'Custom'
Is this because my KNOX may still be '0x1' ??

Yes, it's because your Knox is 0x1. And AFAIK, there is no solution yet, to turn it back to 0x0. And I'm glad to hear, that you have your wifi back

Shame really - AFAIK as long as I have 'custom' (&/or Knox at 0x1) this mean Samsung can refuse the Warranty if I have to send it back at any time (which I hope will never happen :fingers-crossed

How did you flash the firmware ?
Was it through OTA, Keis or Odin ??
I had same problem when updating my firmware via Keis v2.6 (see my post above [First & Last paragraphs] or my original post for a more in-depth explanation)
I managed to fix it myself by re-flashing a STOCK rom (got from 'sammobile' - using Odin) OVER the existing firmware (i.e I didn't hard reset it first - when it finished the phone wasn't wiped either) but the WiFi could now be turned on/off...I then 'CFAutoroot' & 'Triangle away' afterwards - checking each stage to make sure WiFi could still turn on/off
So far 'tripp' & myself have had success in fixing the 'Unable to turn on WiFi' using this method.

[Q] 3g/4g connectivity issues

Hello guys,
For the last month i have been fighting with connectivity issues on my SG4 i9505.
It starts out with just losing the connection and then getting it back, gradually over time it gets alot worse, so that it then requires using airplane mode and back to normal. along with *#*#4643#*#* disabling radio and enabling it again.
The next step is rebooting, but this does not always help, i often need to suppliment this with a cache format, which in new android versions is a real pain, exp with kitkat due to ART with it compiling. Anyway this is fare from the correct solution to do this multiple times a day.
I have also tried factory wipe, etc without luck, its the same as wiping cache with the side effect of losing my settings.
I tried getting a new simcard from a completely different carrier, this has not helped a bit, i also tried disabling 4g so that it only uses 3g (my carrier does not have 2g connectivity and on my previous carrier using 2g only did not help anything.
i started out with the XXUAME2 baseband, and i am now at XXUEMK9 and it has not helped to upgrade it.
I have been unreliable for over a month, phone calls drop, i can't reply to sms's without rebooting/wiping cache etc, asking around in diff irc channels without luck.
Does anyone have suggestions/solutions to this problem ? I really like to get my phone back up and working.

CM11 apparently does not have screenshot support yet, so i'll just manually write it in.(i am running latest nightly)
model number: GT-I9505
baseband version: I9505XXUEMK9
I am from Denmark, so the phone is unlocked.
I started out with Telenor, then Bibob and now Oister as carrier all 3 have had the same issues.
My phone came stocked with XXUAME2 so i am using the correct firmware according to varrious threads around.

1. Use Odin v3.09
2. Untick Autoreboot
3. Flash modem: HERE
4. Reboot manually into Download Mode using (Vol Down plus Home button combi)
5. Flash Modem once more
6. Once done,unplug then reboot device manually.
7. If this doesn't work, try repeating the flash process again while rebooting manually and with auto-reboot option turned off.
* If u have problems with wifi -> Try WIFI FIX too:HERE
Use it with care!!!
Open in Odin as PHONE or CP!!

Hi,
I believe you have flashed a wrong baseband, try to downgrade it. I had a similar problem with mine some time ago, I was with bad signal due to an outdated baseband, then when I flashed a new one, it wasn't compatible with my bootloader... So, try checking this thread to get one better for you: http://forum.xda-developers.com/showthread.php?t=2192025.
I got my luck with the MJ5 baseband, I'm with the old bootloader too (UB).
Hope this helps,
~Lord

Hi guys, sorry for the slow reply, i had to be sure before saying if it was working or not working.
I downloaded the original rom/baseband from sammobile and tried it out, this turned out to be alot worse, due to i am unable to clear dalvik cache with the recovery clear cache.
also due to the lack of *#'*#4636#*#* it made the experiance alot worse.
the baseband i am now using is XXUEMKF with KNOX (so i am now knox 0x1)
I'm currently trying out the google edition, but looks like the issue remains.
funny thing is i do remember it working in the past with some old AOSP/AOKP version.
i'm completely lost, expecially due to its so random.
It gets to the point where i am unable to search for networks, and other times there is no issues.

Update:
Ok i've noticed something very strange, its some how tied into the wifi, when i disable wifi i lose my 3g/4g connection and when i enable it again the connection returnes quite fast. though the connection at points, can get lost again.

What Odin version are you using? Do you have installed kies 3 in your PC? If don't, install it to update the drivers and flash that 4.3 Rom you downloaded from sammobile again with Odin 3.09.
Fyi, once you had installed a4.3 knox rom, you are not able to return to a 4.2.2 stock Rom.

I am using odin 3.09 and kies 3 is installed, its been flashed many times
I've tried multiple reflashings, in fact every day last week was 2-5 flashes a day. I install my apps again and set them up each time, takes quite a long time, just to remove it again later on, got any suggestions to saving my apps and settings along with wifi ? (google restore does not work with all roms and is not always effective).
Googling my issue returns quite a few results with people that have simular issues but no solutions.

Sorry, but I only left to think you have a hardware problem...
You can make easy backups for selected user apps with System Tuner, and if you are root also system apps.
Good luck.

i9505 know and wifi issue

Got an S4 i9505 and I believe it was running 4.2.2. I rooted it with CF Auto Root and everything was fine,
A few days ago, little one messed around and accidently managed to install 4.3 update. Now wifi cannot be enabled giving an error that "your device security has blocked an action that is not permitted"
Clicked on SuperSU and it said that knox has been found and some applications may not work,,,,,decided to disable it and disabling it was successful.
Even now when I try to turn the wifi on, it doesnt work but dont get the above message anymore.
Any help would be appreciated as it's driving me mad.
Thanks

Anyone? Please make some suggestion.

Hi ,
My first option would be to try the so call wifi fix, read here:
http://forum.xda-developers.com/showthread.php?t=2192025
select the same wifi fix as the modem you have installed in your phone ( read first , ask there if there is any doubts)
Second option would be to flash stock rom again and root .

Wifi Wont Turn On ($20 Reward)

Hi, I have a very bad problem and need some tips on how to fix the problem. If you successfully fix the problem for me I will pay you a reward of $20 via PayPal or Bitcoin.
I have a Rooted Samsung Galaxy S5 Verizon (SM-G900V) Running Android 4.4.4
Everything has been going fine and I have used my Galaxy S5 with no problems for around 6 months now, however I ran into an issue a week ago. My issue started after I tried changing my Mac Address (Spoofing it). I used PryFi:
● PryFi
*play.google.com/store/apps/details?id=eu.chainfire.pryfi&hl=en&referrer=utm_source%3Dgoogle%26utm_medium%3Dorganic%26utm_term%3Dpryfi&pcampaignid=APPU_1_ujKoVb-zO4Su-AGNiIC4AQ
I granted root access to the application via SuperSU. I also enabled the 'Mac Spoofing While Connected' option.
When I turned off the application my WiFi was fine for a while, I could turn the WiFi on and off, my problem didn't happen until I did a reboot when I rebooted I was unable to turn on WiFi ever again.
The application PryFi broke my entire WiFi, now I am able to only use the Internet with my data connection WiFi does not work at all.
I have tried a few things, however none have been successful yet.
I have did a factory reset and it still has not fixed my WiFi problem.
The WiFi will not turn on at all. It is stuck on Gray.
Bluetooth works fine, however WiFi does not.
If you're able to help me with this issue successfully I will reward you with $20 via PayPal, or Bitcoin.
Thank you,

Have you done a reflash? A factory reset just wipes /data, won't really fix anything...

Get TWRP.
Clear Cache, dalvik
clear data, system
Flash stock firmware via odin. Will fix the issue.

The wifi system is corrupted..
if u need to fix this you must get the whole rom(os)...download latest stock rom or any cusom rom and flash it via odin..or recovery..this will fix the wifi problem...always take a nandroid backup before doing any changes to system...even i had this issue on my redmi note 4g but its fixed by nandroid backup..coz i regularly take backup....i hopr this helps
HIT THANKS BUTTON IF ITs HELPED

I am really upset about myself for not taking a backup as stated. I will from now on take backups all the time before doing anything that could corrupt my phone from now on.
I still haven't tested this to see if it will fix my phone, I will test this within the next day or so.
I do have a question, right now I'm on vacation in the Outer Banks with no computer access at the moment. Is there a way to do what I require to fix the WiFi problem without a computer?

Yes you can do it through mobil odin or flashfire, i would wait though incase something goes haywire and you get stuck on vacation with no phone, i've been there, take it from me, you don't.

Hi, I have a very bad problem and need some tips on how to fix the problem. If you successfully fix the problem for me I will pay you a reward of $20 via PayPal or Bitcoin.
I have a Rooted Samsung Galaxy S5 Verizon (SM-G900V) Running Android 4.4.4
Everything has been going fine and I have used my Galaxy S5 with no problems for around 6 months now, however I ran into an issue a week ago. My issue started after I tried changing my Mac Address (Spoofing it). I used PryFi:
● PryFi
*play.google.com/store/apps/details?id=eu.chainfire.pryfi&hl=en&referrer=utm_source%3Dgoogle%26utm_medium%3Dorganic%26utm_term%3Dpryfi&pcampaignid=APPU_1_ujKoVb-zO4Su-AGNiIC4AQ
I granted root access to the application via SuperSU. I also enabled the 'Mac Spoofing While Connected' option.
When I turned off the application my WiFi was fine for a while, I could turn the WiFi on and off, my problem didn't happen until I did a reboot when I rebooted I was unable to turn on WiFi ever again.
The application PryFi broke my entire WiFi, now I am able to only use the Internet with my data connection WiFi does not work at all.
I have tried a few things, however none have been successful yet.
I have did a factory reset and it still has not fixed my WiFi problem.
The WiFi will not turn on at all. It is stuck on Gray.
Bluetooth works fine, however WiFi does not.
If you're able to help me with this issue successfully I will reward you with $20 via PayPal, or Bitcoin.
Thank you,
Ferragamo

They dont have a computer to flash a recovery, furthermore, even if they did, or if they used flashfire or mobile odin(assuming they have root), you cant get a recovery on a G900V, attempting your instructions would certaintly brick the phone.

Ferragamo,
Verizon's S5 has a locked bootloader, meaning any attempt to load/flash/Odin anything besides the factory firmware will fail (and sometimes end up in tears).
It seems that a major cleanup and then reflashing the latest firmware should resolve the issue.
You can follow my directions bellow to get it done at home (takes about 30 minutes on a fast internet connection), but yes, you'd need your computer.
Or you can stop by BestBuy and have them flash a new firmware on your phone for you.
Step-by-step Directions:
1- Start by downloading the correct USB drivers for your phone, and install them (open the exe file as administrator on your PC):
http://www.samsung.com/us/support/owners/product/SM-G900VZKAVZW
2- Download and install Samsung Kies 3 software on your PC:
http://www.samsung.com/us/kies/
3- Back up your files from the phone using Kies or copy your files, photos, etc. to your PC
4- Time to clean the phone! Use the 3-button combo (hold volume up + home buttons and press the power button) to enter recovery.
7- use volume keys to scroll down to factory reset and press power to select it. Select Yes to wipe the phone. And repeat this step one or two more times for good measure.
8- hit reboot phone, once the phone's screen goes blank (phone vibrates), pull the battery. Don't let it boot.!
9- Load up Samsung kies on your PC, select Tools tab, and reinitialize firmware, answer the on screen questions to input your serial number from the sticker inside the phone.
10- Once ready to flash the new firmware, put the battery in and boot the phone to download mode (3- button combo hold volume down+home and press power)
11- connect the USB cable to PC and make sure Kies recognizes your phone, if not uninstall and reinstall the USB driver. Reboot PC etc...
FAQ's
http://www.samsung.com/us/support/answer/ANS00043306/997388244/
Downloading the firmware will take a while depending on the connection speed. The file size is around 1.5-2GB.
Be patient and baby sit it until flashing is done.
Important: Do not break the cable connection, and prevent the computer from going to sleep or turning off during this process!
Happy flashing

Thanks everyone for trying to help me out. I'm still in the Outer Banks as of now (10:41pm EST). I won't be home until around Sunday, so if I'm not able to do this process without a computer it will have to wait until at least Sunday.
I have got a general picture on what I will have to do to resolve this problem. Hopefully when I get home I will be able to fix this situation.
Thank you Commodore for pointing out those nice tips and the guide. I noticed you mentioned I could take my phone to BestBuy, unfortunately in the Outer Banks they do not have a BestBuy as far as I can see. The only store I can find is a Walmart, so that probably will be of no use for me.
I would have gone to a public library to try and fix this issue, however this location has no library kind of dissatisfied a little, but if it did have one I would have took time out of my vacation to fix my phone.
If there is somehow a work around via the phone some how I would be willing to test it and hear it out, if the computer is my only option than so be it.
When I get home and fix this situation I will reward those who have helped and reached myself to restore access to the WiFi on my phone.
Thanks,
Ferragamo

how to fix

Yotaphone 2 reboots by itself after after the screen switches off.

Hello
I have a Yotaphone 2 running android 5.0. I have a huge problem with the device which is, that the phone reboots automatically all by itself after the screen turns off. The screen timeout is set at 1 minute and once the screen goes off, the phone reboots! I don't know what the problem is but its making me crazy!
Note: The phone does not reboot if the screen doesn't turn off. So I changed the screen timeout to 30minutes. Also note that Wi-Fi doesn't start immediately. It doesn't even start most of the time and is stuck at "turning on"! And also, the phone isn't detecting my SIM Card!
Hope someone can solve my problem.

Wow, seems a lot of problems here. However you provided very few info about your phone.
1) Where did you buy it?
2) What have you done after you opened it, OTA? Which firmware was installed?
3) Have you tried factory reset by wiping data in the stock recovery? (Accessible with Vol+ and Power)
4) Have you tried to flash from scratch the RU .124 firmware with YotaFlasher?
5) The phone was behaving normally before or it's doing this as soon as you started using it?

I got the phone as a gift

-The phone was a gift from "Aramex Company".
-Yes, I have factory reset it! Note: It wasn't possible to reset it from settings because it would always get stuck in "Shutting Down" phase and nothing would happen. So I hard reset it.
-I found something strange going on though. Whenever I reset it, It would restart (after the reset is over) and say that "ANDROID IS UPGRADED TO 5.0".
I think it is upgrading by itself to 5.0.
-No, I haven't tried any flashing.
-Yes, the phone was working fine for a while and then started behaving like this!
Cheers!
(Thank You for your support and attention by the way)

Video
Hello!
I have made a video showing what the problems are! Please give me your e-mail so that I can send you the "Dropbox" link to the video.
Thank You!

I think the first thing to do here is to flash a clean firmware (RU or EU) on your phone via YotaFlasher, search here on xda how, and then report back if it's happen again! Seems that the firmware it was shipped with wansn't so stable.

Flashed it!

Hey!
As you had prescribed, I flashed it! First I flashed it with Android 5.0.0-ME1.1.60 and after opening the phone I used it for a while and the phone was same as before flashing! There was no difference at all! The phone was restarting on turning screen off as usual, the WiFi wasn't turning on, and the SIM wasn't being recognized!
But then I flashed it with Android 4.4.3-S01-003-ME1.0.3.61a and the phone is still rebooting by itself upon switching the screen off and the WiFi problem still persists! The WiFi just simply won't turn on. It's stuck at "turning on"! The SIM isn't recognized either! Also, the phone is restarting from the inside now (It wasn't restarting before. I had to keep the power button pressed every time I wanted to restart)! But NOTE that the phone still cannot be just shut down, it can only be restarted!
I don't know what to do!
Cheers

Hi lgk350tr,
Why are you unable to make yotaflasher work, it is a pretty simple application. Have you tried to see instruction videos on YouTube on how to use it? Instructions are also available on XDA Developers' website. ( https://forum.xda-developers.com/yotaphone-one/general/yota-flasher-download-t3480922 )
Don't hesitate to contact, for any problem!
Cheerio

Try flashing the hybrid modem mentioned in the general guide (Part 2).
Try flashing 2 times before rebooting.
If nothing helps, you could try lineageos, @angelll123 made a lengthy guide how to that in the post quoted here , also check my comment.

Is this what you mean?

I have attached a screenshot of the Yotaphone 2 General guide page, I want to know if you are referring to the text that I highlighted in the screenshot!
Thank You

I do experience similar issue, but only recently. I haven't done anything like flashing or upgrading my phone, it started by itself .
I am experiencing reboots whenever battery drops below about two thirds of its capacity. Also, charging and handling some load prevents this.
Note that my Yotaphone has both displays damaged. Still working though.
