[Q] WiFi not working after update via Kies from 4.3. to 4.4.2

Hi there,
i have a rooted S4 i9505 with cwm installed.
yesterday i did an update from stock rom 4.3 to 4.4.2 (I9505XXUEMKE) via KIES.
the problem now....I cant turn on the wifi anymore. whenever i try to use the on/off switch for the wifi it instandly switches back to off.
is anyone else experiencing the same problem? has someone already a solution for that, before i will do a factory reset.

hmm - shouldn't really be a problem if you flashed stock, but broken wifi is a symptom reported when flashing old modem on new bootloader, if you have new stock sammy 4.4 then you will surely have new bootloader (check though by putting your phone into download mode and then check for KNOX references - if you got them you got new bootloader, if no then you are on the old one)
Click on the link in my sig for modem - that will take you to a thread that has all the newest modems - have a look through the most recent last 3-4 pages and you will find packages for modems for new bootloader, flash one of these and see what happens - BTW you need to flash in odin with 'reboot' unchecked, then when its finished power off your phone manually then put back into download mode and flash again, then repeat the procedure but this time tick 'reboot' and that should be done. BTW - the tar file goes into 'phone' not csc. You may need to unzip the modem package to get the tar file.
Let us know how you got on

you are on the new bootloader so you can flash the complete package - it has everything in it all in one package! - you won't brick your phone even if you flash the wrong modem, that is unless you did some thing real dumb like flash i9500 modem and even then I think its recoverable not that I suggest you try!!
depends where you are in the world - I used NB8 and it worked well for me in the UK - I'm on NB9 now and that seems nice also.
so to be clear flash this:
Combined package
For NewBootloader
GSM_Modem_XXUFNB8_and_LTE_Modem_XXUFNB8

hey guys, thank you!!!
the Wi-Fi is working again.
Nonetheless i still have one problem remaining, which i thought it would have been fixed as well.
but, when GPS is turned on, it tries to find the GPS position and the icon on the status bar continues appearing and disappearing permanently (every half of a second).
Beside the fact that it is really annoying having this icon flashing all the time it also causes the display to freeze.
Especially when scrolling from top to the bottom to open the notification area.
It sometimes also lets the system crush completely.
any idea what this could be?
thanks for your effort so far.

hmmm......... thats not right!
Suggest you find a stock sammy ROM and flash anew in odin - then root using cf root, then flash recovery - (TWRP is very good :good then go into recovery and wipe cache, dalvik, system and data - reboot and see what happens on nice new shiny sammy stock - if all is good pick the ROM/kernel you want (if you want) and go back to odin to reflash modem.
The only other thing I can think is that you have an app that is messing with gps?? Do the above though and you should be golden :good:
EDIT: don't wipe system unless you planning flashing a different ROM through recovery!

Hi, right way to flash the stock Samsung package, but after flashing a custom recovery, do not wipe system. There's no ROM after that so phone will not boot. And the newest modem is integrated in the stock package, so no need to flash it again.
And another advice: NEVER use Kies to update your phone. It has bricked 3 of mines.:cyclops:

Oops, well spotted! Yes, don't wipe system unless you have another ROM to flash through recovery. 3 phones bricked from kies huh? I never used it SVD don't think I ever will lol. Good old Sammy stock stuff, tbh that's why I steer well clear of anything stock Sammy unless absolutely necessary and last resort - I look at the farce they have made by forcing us to accept Knox pox!

my thought was to go into recovery mode and wipe everything and start from beginning in order to exclude that it could depends on some wrong settings or any software already installed....

I updated to 4.4.2 using Mobile Odin and my wifi was borked too.
I did notice after the update that there was a mismatch between my Baseband version (still the old 4.3 XXUEMKE) and the Build number XXUFNB8, and I recall seeing some message during the flashing process that security had blocked the kernel update and Triangle Away might help solve it.
I therefore ran Triangle Away to reset my flash counter, and then used Mobile Odin to have a second go at flashing just the Kernel, Recovery and Modem parts.
This was successful and I now have matching Baseband and Build, both XXUFNB8.
And my wifi now works again...

ok.. after making a factory reset wifi and gps are working fine again.
guess there was some missconfigured third party app...
but now, with a fresh system i do not understand why i am not able to assign a PIN for my lockscreen...
everything is greyed out except PIN and Password.
but even though setting up a PIN, the screen lock is always set to use Swipe......
damn, i shouldnt have updated to 4.4.2.... until now.. only problems with this new build....

Having an impossible time flashing CM11 rom, been at it for hours please HELP

This used to be easy.
After 8 hours yesterday I think I managed to root the phone. CWM/TWRP will not install. At all, under any method. Rom manager, goo manager, I now get this stupid message that says that "an application attempted to access something unauthorized and has been blocked" over and over.
Just trying to flash CM11 rom. Guess I need to learn how to sideload or something? I physically can't get my phone to recovery mode other than the stock Android, which does not have the "flash zip from sdcard" option.
For the love of god help me. My phone stopped working around 2 pm yesterday and I seriously can't believe I'm about to be going into day 2 of this, so rather than drive myself crazy i'm going to wait for help

bump please help should be simple

Hi,
Please, don't panic! Panic is your worst enemy . First, give a good read here: http://forum.xda-developers.com/showthread.php?t=2419762. Then try again . It's very likely Knox is blocking your TWRP/CWM installation, that's why you receive this message.

Hi,
Please post your installation issue on the Galaxy S4 Help Thread there might be someone better than me to help you there. Also are you sure you're flashing the right files and using the right method? Did you try another USB Cable? Did you try another Odin version? It all can contribute to the fail.

its the official samsung cable. and yes i tried others
tried other versions of odin as well
and different versions of both twrp and cwm
its crazy i tells ya xD

If it fails to flash true Odin, then you are doing something wrong.
- Different pc
- Reinstall drivers
- Different cable
- Different usb port
- Make sure kies is not running in the background
What are you running? Windows 8? Try a windows 7 pc.
Post the details of the error you are getting.
Also when the flash goes succesfull, but you still don't have a custom recovery, then uncheck auto-reboot.

can someone please link me to a guaranteed working version of a flashable recovery for odin ?
I know its a lot to ask but I've actually gone through almost that entire list you listed
tried diff cables
no kies runnning
on windows 7
drivers been installed twice
maybe i should try the other port, but in case that doesnt work can anyone just link me? sorry i've just never had this much problems with this, must be b/c of the new security knox update or w/e in oct of last year. Last June I did all this in about 15 minutes....

I had the same trouble with the knox crap yesterday, the only way I could get it rooted and/or with custom recovery was to use the Cyanogen windows installer, then when CM booted I then rebooted into recovery and installed a different rom from there. :good:

Hi i know youve already said said its officail cable but im saying try another different s4 cable. Because when i was installing recovery or anything it wouldnt let me (i thought i had original white s4 cable) but then i got my dads cable (hes gt s4) and it worked instantly. These fake cables are at large and its very very difficult to tell if its original.
Also like previous guy said using a different computer/laptop also helps i know because ive flashed my phones since day 1.
GL and plz let me know if u managed to fix it another way as its always good to try new options when others fail.

It will get you to download the installer (or http://dist01.slc.cyngn.com/CMInstaller.msi?t=1403660099360) the click it to run, It may download an update for itself, then it will download recovery, operating system, gapps, then start to install everything. About 300mb altogether.
That way you don't need the tar files, just search on this sight for flashable from recovery for the recovery files you want. (I use the touch versions myself).

So do you have an AT&T phone? If you do, you are in the wrong section of the forum.

Unfortunately all Applications are stopped when booting, cannot start phone - Urgent

I am newb to android world.
I have Samsung Note 3 SM-N900.
1. Succesfully installed lollipop 5.0 on this phone after reading for a week on this site.
2. Was planning to root the phone, followed instructions from here:
CF-Auto-Root is pretty much only method for Lollipop at the moment. Yes, it does trigger the KNOX Warranty Void flag though, look it up if you want to know what it means (voids warranty in certain regions apparently, definitely not in EU).
Instructions are in the first post of the CF-Auto-Root topic - http://forum.xda-developers.com/show....php?t=2466423

Thanks mahi,
I am able to boot into download mode hoding volume down button and recovery mode holding volume up button. Should i try to do following in present condition without Reflash lollipop rom
Wipe cache
OR
factory reset
Data is not important as I have all my important data on memory card (video/images)

Phone is alive again:
Did following things to recover the phone which was not booting:
1. wipe cache partition
Nothing happened, was still getting those application stop issues, phone was unable to boot.
2. wipe/reset data
Phone came back alive.. all applications got uninstalled except Super-Su Free from Chainfire.
I am able to open the application Super-su properly.
How can i confirm.. If there is nothing wrong and proceeding ahead with setting upon the mobile again.

Edit 2
Went to Recovery Mode and Download Mode, did nothing..
Again started having the same boot issues, all applications getting stopped

Probably.. should reflash entire thing again.. ?

Reflash the ROM via odin, then factory reset and clear cache before first boot.

you have one solution go to download mode , go to sammobile download the official firmware for you device and your country connected your device with pc download the lateest version of odin . install and oppen odin go to pda .chose the firmware that you downloaded from sammobile install clik start and the problem soved

Not sure.. How i updated lollipop last time or rooted device . (local mobile repairers who work for rooting when paid are not at all knowledgeable)
I always got STOCK recovery MODE option, just tried to get into recovery MODE on a Note 2, and got same menu options.. like i have in NOTE 3.
Few minutes later, followed all instructions in this thread again:
Thanks to dr.ketan and cryostasis25..
I used same file again = n900-cwm-recovery-6.0.5.0-kk_L5.0(0812).tar
And now I am getting a different recovery MODE option..
(PROBABLY, i have to MYSELF spend more time reading/understanding terms.. before going ahead).
Now top title of recovery mode displays "CWM-based reocovery v6.0.5.0"
Giving few many options to select from list. (I never got this recovery mode before ??? )
All my last wiped applications are intact as well.. (wiped around 6-8 hours ago)
http://forum.xda-developers.com/showpost.php?p=58775300&postcount=5
I am not sure still, what i tried/did.. Any guidance shall be a miracle.. for a newb
Tried going to recovery mode/download mode several times now, and phone wont crash
Kindly let me know what/where i did wrong..
Edit 1
I am also getting an option now to install dr.ketan ROM from recovery mode.. will try that for sure 
Once I receive some responses (to a newb)
Edit 2
I can still find I am rooted, Chanfire su app still appears installed and runs perfectly fine..

[RESOLVED] [Q] SM-G900W8 Stuck at boot screen after editing build.prop

Okay, I've searched the forum for several hours but there's just too much here to make sense of.
My phone is a SM-G900W8 brought home June 19 this year.
Stock Lollipop 5.0 pre-installed.
Code:
Baseband version: G900W8VLU1BOC1
Kernel version: 3.4.0-4100894
Build number: LRX21T.G900W8VLU1BOC1
SE for Android status: Enforcing, SEPF_SM-G900W8_5.0_0002
KNOX version: 2.3
Rooted using CF-Auto-Root (this file), Custom recovery is Philz Touch 6.57.8 klte.
Both of these were in place early on and haven't caused any problems.
Everything was working perfectly fine until last night, when I tried this trick (in first post), rebooted, and now I'm stuck at the splash screen.
Nothing gets me out except a battery pull.
I've tried:
Button combo volup - home - power to go to recovery; this does nothing from the splash screen (actually even pressing and holding down power does nothing), and after a battery pull it won't boot into recovery either.
Booting into download mode (success! yay!) and using Odin to re-flash Philz recovery. Reboot doesn't go into recovery, as stated above.
Just waiting, at various points in the process (while in splash screen, while turned off) to give a chance for things to happen if they just needed time.
So now I'm able to get into download mode and use Odin but from there I don't know what to do next. Flash the bootloader? Okay, but there are so many links...which one do I use? Of all the specs I've gathered, why didn't I find that out?
Can somebody help me please?
[EDIT: Solution and links, for SM-G900W8 users who might be looking for help]
I finally managed to boot into recovery by leaving the USB cable connected to the computer while pressing volup+home+power, a last-ditch trick found in deanr1977's very helpful thread "Read before flashing a Rom (Tips for new & old)"
Links to the firmware for this specific model can be found here, or if you just need a piece:

Okay, I've searched the forum for several hours but there's just too much here to make sense of.
My phone is a SM-G900W8 brought home June 19 this year.
Stock Lollipop 5.0 pre-installed.
Code:
Baseband version: G900W8VLU1BOC1
Kernel version: 3.4.0-4100894
Build number: LRX21T.G900W8VLU1BOC1
SE for Android status: Enforcing, SEPF_SM-G900W8_5.0_0002
KNOX version: 2.3
Rooted using CF-Auto-Root (this file), Custom recovery is Philz Touch 6.57.8 klte.
Both of these were in place early on and haven't caused any problems.
Everything was working perfectly fine until last night, when I tried this trick (in first post), rebooted, and now I'm stuck at the splash screen.
Nothing gets me out except a battery pull.
I've tried:
Button combo volup - home - power to go to recovery; this does nothing from the splash screen (actually even pressing and holding down power does nothing), and after a battery pull it won't boot into recovery either.
Booting into download mode (success! yay!) and using Odin to re-flash Philz recovery. Reboot doesn't go into recovery, as stated above.
Just waiting, at various points in the process (while in splash screen, while turned off) to give a chance for things to happen if they just needed time.
So now I'm able to get into download mode and use Odin but from there I don't know what to do next. Flash the bootloader? Okay, but there are so many links...which one do I use? Of all the specs I've gathered, why didn't I find that out?
Can somebody help me please?

factory reset. Then flash stock rom. if you cant boot into recovery try the latest twrp. It works if its still not working then flash stock firmware from SAMMOBILE with odin. it will work then

Thanks for the reply. The problem I'm having is knowing where to download the files I need to flash - because there are so many threads here for so many different models of this phone. Believe me, I've looked, and keep turning up everything BUT W8
I'm tired and frustrated and need my phone functional - can you point me to a post or a thread with the latest version of TWRP that I can flash with Odin?
[edit] Sorry about that - I found the thread. I'll give that a shot and see what happens.

EDIT: THESE TOOLS ARE FOR 900F MODEL
Latest twrp from https://twrp.me/
Philz recovery from https://mega.co.nz/#!oVNz0T6C!VII47M...MpQIN2b-PEUYN8
Best Stock firmware 5.0 BTU from http://www.sammobile.com/firmwares/download/44413/G900FXXU1BOC7_G900FOXA1BOC7_BTU/
Enter download mode and Flash either one of the recoveries and Clear dalvik cache, clear cache, format system, format data and then factory reset. After that boot into odin mode directly and flash the Stock Firmware.
note: in Odin uncheck "auto reebot option" and after flashing recovery when the odin shows its done wait 1 minute disconnect usb and pull out battery then turn it on if your phone says "Recovery is seandroid enforcing" wait for 3-4 seconds it will go away and recovery will boot up.

Now, I just want to check: this is for the G900F; will it make a huge difference to my phone? Can I restore my data directly from the backup? I thought what I needed is the exact stock rom that was installed on this phone when I got it so I've been looking everywhere for the G900W8 firmware. I do intend to play with tweaked ROMs in future, but today's not that day.
Finally managed to boot into recovery after flashing TWRP - read a tip somewhere about doing the keypresses while connected to PC via USB. Currently running a nandroid backup before moving on to all the wiping/formatting steps - at least then if something else goes wrong I've got the latest data. :victory:

i am sorry the tools i mentioned are for 900f model. Here http://www.sammobile.com/firmwares/database/SM-G900W8/ you can find firmware for G900W8. Just factory reset format dalvik cache, cache , data and system and flash your stock firmware in recovery. There are many different firmwares available with the exact bootloader and modem but they are carrier specific. I don't know which carrier you are on (if any) so just go through the list and download the firmware you were on, flash it. I will highly recommend you to backup your EFS and modem folder aswell just incase anything goes wrong and u flash the wrong firmware.

Oh! Oh! I found it! The stock ROM, as well as the kernel and the modem! So, next question - should I flash all three or just the ROM?
(God I feel like an amateur right now...Thanks so much for helping me out here dork997. :highfive: )

no prb, Okay if you download the rom from sammobile it should be in a .zip format extract it once and it will give you a .tar.md5 file which you have to flash in odin (this file has bootloader+firmware+modem) if you have 7zip or other such programs it will give you option to re-extract the .tar.md5 file but you dont need to do that just extract the downloaded zip once. and flash it in odin (make sure you factory reset and do the formating steps before flashing it....flashing rom over an old rom has caused some issues for me in the past so i always factory reset before but people also flash without factory reset or formating, choice is urs.

And I believe you've just answered my question. I'll hold off on flashing kernel and modem but I did back up everything, just in case. Wiping/formatting now; crossing fingers that things will go fine from here.
(My carrier is in my userinfo under my name, btw. )
Edit 'cause we keep posting at the same time: Hells yeah, I know how to flash, I've done it tons of times, just never run into this problem or had a device with so many variants so I'm just not used to asking so many questions, is all. I sincerely appreciate you guiding me through, and hope this will help others with this device in the future.

cheers, if it does help you just try to give it back to the community.....i ve had similar issues and people here on xda helped me out. So i am doing the same.

FYI - It worked like a charm and now Lexie (I name my phones ) is up and running again almost like nothing happened. Thank goodness!
In case anyone else winds up needing them, I'm adding links to the stock firmware I downloaded.

Huh, i really bricked it! (SM-910F, endless recovery loop)

Hi folks,
i have had many devices and virtually customized every one. Now i have really done it, i bricked my phone.
I did happily flash the new march updates for the 910F, some dr. ketan, just the usal stuff. However, now my phone boot loops in and out recovery. To be precise, it starts after successfully flashing with odin (does not matter if repartition with pid files or full nand erase...):
- it tries to enter recovery (blue text at the top)
- it fails (nothing happens), then it goes black, it vibrates two times and
- restarts with trying to enter recovery (endless loop)
No getting out. Removing battery and starting normal does not work.
Download mode and flashing via Odin and Kies "does" work, but changes nothing....
Does anyone have ever had similiar issues and or fixed this?
All thoughts are welcome.
Greetings from germany...

try to flash only the stock recovery.
If it fails, flash the last stock with pit file + factory reset on recovey, if wou're again in bootloop

I did the same thing on my note 10.1
"your partition is corrupt. Would you like to factory reset your device?"
it is still here in bootloop..

Do you have a recent stock recovery flashible with odin or do you know where to find?
I did flash the recent stock with pit files/repartitioning,...does not help.

How do you know the partition is corrupt? I think i already did a factory reset by repartitioning with the pit file. Corrupt partitions i tried to fix by nand erase in combination with repartitioning... this did not help.

I have the same problem, only problem I got some text with red+blue+yellow color, what I did was flash a stock ROM ( SAME ROM I HAD BEFORE ROOT FAIL) and it worked (like)

any flagship Samsung is bricked if you can get into download mode.
if you want to try, above you have the recovery from the last S1CPC1, flash it at odin:

thank you very much. i do not understand your first sentence......btw. i can get into download mode...(just if you meant "can not")

Update: I have virtually flashed every rom > 5.0. No success, no difference. Everytime the odin flash procedure is successful (in all variants, with pit, with nand erase, etc...), but the phone loops everything (normal start, recovery) besides the bootloader.
only new thing i noticed: allthough binary status is official, the device status is and stays custom not matter what i flash.
anyone? anything?

Did you try to flash the stock recovery yet?
Also, what did you exactly flash to cause this?

yes i tried stock recovery already. not sure what caused this. i do remember that i had some problems with 4.8 debloated and then i wanted to flash the hole corresponding stock package as clean base. somewhere in the middle this happenend. i am not quite sure, but maybe, maybe flashed cf-autoroot to this march update. but i am not sure if this was before, after or initially.
however,...what really bothers me, is that there is absolutely no indiciation for an error during the flash process. odin and kies, everything completes just fine, just booting does not work. that's why i fear, that this is just an ugly coincident and the problem is caused by some failing hardware.
maybe and immensly undclocked kernel (odin flashable) could start my phone. because something is still working, when the bootloader and the nand writing is working just fine.
does anybody know how to get a really granpa speedy kernel, or how to make it?

Used to happen to me all the time. What I used to do was, after flashing the rom, connected it again to odin, flashed the cwm recovery 5-6 times and then used to give it a try. Also ,after trying this, flash the bootloader-modem file and pretty sure your phone will boot(This is optional)

Greetings from Hamburg ☺
I was having also huge bug with dr.ketan rom at first was working flawlessly and 1 month later my phone wouldn't charge at all or recognise any charging cable.
Good thing is you can enter download mode (odin )
That means your phone is only soft bricked.
Flash SM-910F pit file + Latest stock firmware in odin mode all together in 1 flashing process...dont forget to mark repatriation in odin when using pit file.
When you got pass on odin and phone reboot and you see Samsung logo...fast take battery out and wait 1 min , put battery back and hold combo to enter stock recovery and do factory reset.
Good luck :fingers-crossed:

Thanks guys. I tried yesterday some stuff, nothing was working and i finally got it dead as a stone! Nothing was working anymore. However, i took it to the samsung service center. They were irritated, that they can't get it on at all! ... However, i am curious, how they handle it and how much they want for a repair attempt/or replacement.
Just for info. I did all the things you proposed. Nothing worked. I think this was just a coincidental hardware failing. If you flash all the time, there is a chance that you do it, while something is dying!?
i keep you updated! Thanks for now...

Corrupted eMMC? Probably! Please let us know what the service centre said ultimately and how much they charged you.
