[Q] [HELP] Wifi dont turn on, can't call after debrand

Hi, i have problem after debranding my galaxy.
Wifi is not turning on, and i can't call, when i try, there is a black screen.
I have branded PL in "Plus", and i tried with xeo roms from april (I9505XXUAMDE) and may (I9505XXUAME2) and modems for them.
When i tried first time to change rom, i had error in odin (can't write or something like that). So i rooted my device using cf-auto-root, changed csc from btu to xeo, then I9505_OFFICIAL_STATUS_MOD, wipe and triangle away, then rom.
How i can fix that?

If I be you - i try to go to Advanced phills touch recovery menu, format there everything (system, data, partitions EVERYTHING) except sd card. Then i would like to try to flash Android OS (4.3) with repartition (pit file if I remember it correctly). After that, the good idea is install root, than phills touch again (I don't remember, but something overrides another one and recovery menu dissapears or...whatever, need to try) and test again if you have this issue.
Giving this information you gave, it's even for SUPER DUPER PRO EXTRA HIGH-RANKING with IQ over 9000 developer is actually impossible. Anyway, I'e just told you the best way how to fix it.

I found somewhere similar problem, and i tried to install 4.3 rom, and everything works fine

[Q] GS4 - How to return completely stock for warranty exchange

Hi,
I've been do many flash last 24 hours on my Galaxy S4(Model SGH-I337M, Telus). Initialy, i've the factory stock rom, rooted. So, yesterday, i've decided to install Cyanogen mods nightly on my phone. Not the first time i've been used it on my phone. No problem before. So, this night, after a friend show me the release canditate release seem to be more stable, i've been try to put it on my phone. So, accidentaly wipe all the data on my phone. When i'm back home, i've put again the samsung original rom from my operator(4.2.2), found here, on the website, whit odin. All completed succefully, but i've noticed that the wifi won't turn on after the flash, and no sound from the speaker. So, i've put Cyanogen nigthlies again to test if it rom relative, but same issues here, no sound, but the wifi was working. The phone was very instable, so. Then, finaly, put the original rom again, without any rooting. Stuck on samsung logo, that i've finaly got fixed by clear the data and cache. But, no sound, and no wifi. Instable too.
Precision about phone: Unlocked whit the service mode(work), and enabled AWS whit a software and file(tutorial found here)
My question is: Anything else i can do to make my phone work fine again, and does it's possible to make the phone totaly stock? When i boot up, i've noticed that the phone, whit all rom i've try, said on samsung logo: Kernel is not sendroid enfonced, warranty status: kernel, so i can't go to return my phone on warranty whit that. How i can erase that line, and make my phone seem to be no modified?
Just to specify, it's not the first time i flash a phone. Do many flash, whit galaxy s2, s3 and s4, and sure, mine. Got try Cyanogen, stock, know how Odin work and all, try many rom, and before today, never has any problem to do turn back, but now, it's seem to be impossible.
Thank you very much for your help, very appreciated!

I would flash the stock firmware with odin again. After flashing do a factory reset in the stock recovery.

I've just try this. Flash the stock rom whit odin, and factory reset on original recovery after. Same, no wifi, no any sound.
Just see yesterday, when i'm flashing, i'm flashing on the bootloader in odin(whit the tar for the stock rom). Today, correct this by flash on the pda section, still not work. Found here on the forum the stock bootloader, rom, csc, and modem, but when i do this whit odin, odin said fail.
Thank very much, i think my phone is dead, and nothing to do to exchange it on warranty.

I think Kies has an emergency firmware recovery mode.... maybe that'll work.

Just try this. Kies is the worst software i've ever see. The software completely freeze random. When i go to the emergency menu, never, kies recognize my phone here. I've tried to plug my phone, no recognized. Tried without plug it, no recognized. When i plug it, kies said connection in progress, and can stay here 30 min.
I'm a idea of what is my problem. Before do install of cyanogen, i've been applied the samsung official 4.3 update, whit knox. And, according to what i read on many forum, knox is not ereasable, So, it's completely freeze my phone, and nothing to do.
Anyone have the factory telus bootloader and other factory stock items because i want to put it stock.
Thank.

Finally get problems fixed by take the TELUS stock 4.3 ROM and flash it whit Odin. After, can flash cyanogen nightlies again and the phone work well again.
Whit the stock ROM, didn't see any line on the Samsung boot logo that i've rooted. After root this appear again. Knox regardless of ROM installed said 0x1.
If anyone have a fix to put it again 0x0 very appreciated otherwise the phone work fine and thank you very much for your help.

@Spacemonkie4207 never my itune was freeze, and i can do basic operation like transfer music or create playlist without any problem. My kies stay on connection in progress, and turn, turn, turn, but never connect. And when it connect, only one operation, and kies completely freeze, stop responding, need to close it, and open it again. Tried many cable, usb cable, reinstalling software, two other computer, but nothing to do.

I recovered back to stock from custom to 4.3 however if you do so, depending on carrier you could lose root and the ability to install custom recovery.
I would revert back to 4.2.2 (as it's knox free) go to samsungupdates (google it) and pull the 4.2.2 for your region and carrier. flash with odin 3.9
you'll lose root, but you can always perform again as long as not on 4.3 (with 4.3 u can still root if you remove all the knox stuff, u just lose warranty).

Problems going back to stock

Hi,
Was running CM11 on my GS4. I want to go completely back to stock however I'm hitting issues with it.
Downloaded the 02UK firmware file from Samware, flashed it in Odin, did a wipe before and after. Takes a while to boot in each time, sometimes needs a battery pull etc.
Now, I can load up fine - however no matter what I try, wifi won't turn on, a lot of the time signal will drop/ turn off when I lock the screen. Have tried flashing 4.2.2 as well, exactly the same and on the latest flash noticed as issue with the recovery, won't allow a data wipe/ partition in recovery, just flashes something red and then reboots.
I know this has probably been asked a milion times before. But hoping someone can help me get back to stock without the issues!
Thanks in advance.

Your having a signal issue because you need to flash a diffetent modem mate. And that should fix ur problem on signal issue . Do you mind booting into download mode and check if iy say the entry knox warranty void. Thanks
Sent from Hell ?

Currently 4.2.2 as I read the 4.3 update had caused some of these issues (although I want to be on stock 4.3.
I did notice after I posted that the baseband was for German phones (no idea how that got on there). So I flashed the a new modem and baseband is now at I9505XXUEMK8 which is supposed to be the correct one (if not please advise!?). However Wifi still not working. Tried the wifi fix file for the baseband, didn't work, also tried the root /data/misc/wifi/wpa_supplicant rename fix. Didn't work.
Are you able to tell me which Stock Rom/ Modem etc to flash or anything else to try??
Thanks in advance!

Try to find the right Stock rom from here that base in your country mate and flash it via odin . Like i told you if you boot into download mode and check if there is knox void warranty? If you dont have that flash inly 4.2.2 stock rom but if you see that then feel free to flash a stock 4.3

Ok - So I have flashed the UK 4.3 BTU rom (Jss15J.I9505XXUEMKF) and have a baseband of I9505XXUEMK8 (which was the O2 one). Signal is fine no issues etc.
Still Wifi won't turn on though.
What do I need to do for this bit??
EDIT: As per your last post, I have no idea about Knox? I didn't see anything show up on download mode.
It also doesn't seem to be working now. The rom crashes when calls are received and wont dial etc. Ok - so should I go back and install the earliest 4.2.2 Rom version for 02 as the phone came with? Then update through OTA?

Well I told you if you dont have an Entry of Knox Warranty Void when you boot into download mode then flash the 4.2.2 Stock rom :S But you already flashed the 4.3 so you can no longer downgrade to 4.2.2 ... Can you please Dial *#1234# and write it down somewhere . and then Download this Wifi Fix and flash it Via odin and After reboot still did not work then Try to download and extract this file and Flash the .tar Via odin by selecting Phone/CP And if this file did not work after flashing then please feel free to play one of the wifi fix from Here Start's from MK9 until MKE might fix your issue.

Thanks for the help Repulsa. Will try that shortly and let you know the results!
EDIT - What about the Rom issues itself? I haven't had a chance to test everything, but I can't make calls. It calls the person but the screen freezes blank and then flickers. Should I reinstall the rom first or use another?

Tried everything from you earlier post except going through the final wifi fix versions. Nothing has worked so far though....

I'm in pretty much the boat.... I was using Omega ROM 4.3 but wanted to go back to Stock unrooted firmware.
I flashed Stock 4.3 (XXUEMKF to be precise - both Baseband and Build) using Odin 3.04
Now I cant turn wifi on
When I go into Download mode I dont have any KNOX lines and my Binary is Custom not stock!!!
Don't want to mess things up anymore than I already have by trying to flash everything under the sun!!!!
Back to using my faithful Note 2 for the time being then I guess!!!

[Q] Wifi lost; Unique problem maybe.

Anyways as my title says, i don't have wifi. I had first rooted my phone, but then I unrooted my phone by flashing some unrooted os on the samsung which caused two problems. My wifi and mobile data didn't work at all, but after I took it to a repair shop they fixed the mobile data and got it working again and rooted my phone but not the wifi part. According to the person that tried to fix my phone, the current android os, 4.3 - jellybean, that i flashed via odin is preventing the wifi from working. I don't really know whats wrong with the phone but can anyone help me? Also by baseband version is 1337UCUFNJ4 and the build number is JSS15.1337UCUEMK2. Should i try to find a ROM that matches my baseband version and flash it via odin? Thank you in advance!
P.S. This is my first thread, so please tell me if i violated any rules.

im having the same problem and i think we both have knox stupid security back on the phone that's blocking the wlan to start from bad permission or encryption
so personally yeah i will install back the original firmware (before 4.3) from factory reset (or via odin if i have to force it) then im gonna re-root the phone
having back permission ill remove knox (probly with titanium) lock and box bs from base firmware and probly remove root right
then im guessing ill have my internet back now will i go full rom again or basic function thats a good question
so many freaking remote exploit lately
ill let you know if that fix it

I also just found this
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.

seems that clicking auto reboot might be the cause

so would i install the I337_NJ4_Stock_Kernel.tar.md5 file following that method or would i have to find another firmware/rom/(i don't know what to call this) unrooted

[Q]SOLVED Noob GT-I9505 WIFI dead after upgrd 4.4.2 searched and tried all solutions

First of all please forgive me for opening yet another S4 wifi problem after kitkat upgrade, but I have tried everything I could possibly find here, on youtube and other forums. The only thing left to try is flash the modem but I'd rather ask before I brick my phone
I'm not quite sure if this is the same issue every single time or if in my case it is due to my ignorance and errors. I was an iphone/unlock/jailbreak user until last year so please bear with me. Android is new and fun (but scary) territory to me.
Situation, what I did and possible mistakes on my side:
-I'm in Spain but I bought my factory unlocked phone on amazon and it was for the Polish market (GT-I9505 Black, 16 Gb)
-My device was rooted don't even remember how I did it last year so no useful info on that side a part of using odin for windows.
- Until yesterday I was on jellybean, not quite sure if 4.2.2 or 4.3
- Yesterday I upgraded to 4.4.2 via mobile odin and yes I checked the boxes about clearing/deleting cache or whatever it's called.
- Used a stock firmware downloaded from other site (that one starting with "S" and with a great amount of firmwares for samsung devices of several countries)
- I chose a firmware randomly (maybe this was my mistake) because I hade read that the firmware was not that important and people where usimg leaked german firmwares on on phones from elsewhere. But I did choose one that matched the country of my phone (XEO/XX Poland)
- Everything is working fine but without wifi I'm buying new Mb bundles almost every 2 hours and I'll be broke very soon
If you guys think the solution is flashing the modem which file should I use? I see lots of them with different models/codes and I'm completely lost and have read a lot about messing with bootloaders/modems etc bricking devices so I'm freaking scared and ask for your charitative help!
All the info I could gather about my device right now (now I know I should have gathered this info also before attempting to upgrade but it's too late now!

Thank you so much for your helpful reply Joku1981 !!!!! You made my day!!!
Can I do that with Mobile Odin??? My PC broke (Graphics card burnt) and until a couple of months won't be able to buy a new one.
To make sure I understand you: You mean Flash again the same firmware I used to upgrade to 4.4.2 in the first place?
I used this Firmware: I9505XXUGNG8_I9505YXZGNH2_XEO
should I try Flashing that same Stock Firmware again? and if does not work keep reflashing until the baseband and the bootloader get updated?
Why did they not update ? is this common or an error on my side???
I hope it can be done with mobile Odin since I can keep my root status, If I have to do it in Desktop Odin do I have to Re-Root after flashing???
Thank you so much for you kind help!!!!!!

SOLVED!!!!!
After nobody answered if I could use again "mobile Odin" to flash once more and try to fix my wifi not working I opened mobile odin and it gave me a warning about my version and having a wrong bootloader as a possibility of soft bricking my phone so I decided to stay away of mobile Odin this time.
I used desktop Odin (at work since my pc broke) and exactly the same firmware file downloaded from sammobile (but re-downloaded it just in case) and had to flash twice, the first time it went through the whole process ok right until the end where it showed the FAIL message.
I didn't know if I should turn off the phone stuck in download mode and with the process bar at 100 % or retry flashing without turning it off. So I decided not to turn it off (afraid it would get soft bricked or something). I closed mobile Odin but left phone On with download mode screen active and opened mobile Odin again got the "added"message and the blue color showing it was properly connected to the phone and started flashing process again....
I started getting red error messages saying the progress bar display was wrong (and it wasn't updating/kept stuck in the previous 100%) but after it finished it was flashed and everything was ok. WIFI WORKED!!!!!!
Now the weird part.....in case this happens /helps someone else:
- My phone DID NOT get wiped. My launcher and my apps stayed intact (I thought flashing even the same firmware always wiped data, I'm I wrong???)
- All my root apps (root explorer, titanium backup, so on and so forth) where there and working fine. One root checker stated I was rooted and another one stated I wasn't but even my launcher (nova) was working just as if I never flashed the phone.
- Since I was unsure of my "root" state and I did not have "supersu" app in my apps drawer I tried installing it via playstore but It always gave an error message (the application could not be installed in the default location)
- I rooted again just in case and the root process finished without errors but still I had no "supersu" app and one root checker said I was rooted and the other I wasn't. Tried installing "supersu" from the playstore but same error and could not get installed.
- I searched here and in other forums for similar problems/solutions but nothing worked until I tried several things that fixed the problem. Not really sure which fixed it so I will write them down in the order I did them:
1. Opened folder mount which I already had installed and it gave me an error and asked me to try the fix which I did.
2. Opened linked2sd which I already had installed also previous to the firmware flash. It gave me an error and asked me which was the partition to use (as when I first installed it) in my case it was ext4. And it seemed to start working as it normally does. No further error when reopening it.
3. Rebooted the phone and tried entering recovery mode to wipe cache etc but It never entered recovery mode. I get the message about going into recovery mode (top left corner small red letters) But right after that it reboots and I get the samsung logo and my home screen.
4. Tried reinstalling supersu again and no success. (By the way before I did all this steps I tried rooting again but got to the same point. No supersu on my apps drawer)
5. Downloaded BusyBox install (opened it but did not use it in any way, maybe something in the installation fixed my problem)
6. Opened mobile Odin just for curiosity sake and it opened fine and asked for downloading of the extra stuff as when I installed it the first time. After that I closed it
7. Rebooted normally (no recovery mode since I'm stuck without it)
8. Tried installing "supersu" and NOW it worked!!!
9. Checked in both root checker apps and both confirm I'm rooted and supersu started asking for granting permissions to apps again as it normally does!
10. Everytime I attempted flash, root, and even after some reboots I took the battery off (since I read in several threads it helped/was mandatory)
Conclusion now my WIFI problem is fixed, my root problem (that appeared doing the reflash for fixing my wifi problem) is also fixed. The only thing I could not fix is not being able to get into recovery mode.
Does anyone know a solution for recovering the ability to get into recovery mode????
Thanks to Joku for lighting me into re flashing once and again until my wifi was fixed!
