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?

IMEI is the same, except for an extra /1 on the end?? Rest as follows;
AP I905XXUEMKF
CP I9505XXUEMK8
CSC I9505BTUEMK5
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] S4- sgh-m919 calling/wifi problem

I just recently bought this phone off someone dont know what they did with it. phone has good imei. But when i make a call the phone seem to freeze or when i get incoming calling the phone freeze. Also the wifi wont let me toggle on. Cant seem to figure out what the problem is. If someone got a solution please do share.

1. Take a look what android firmware is using (Settings - General - About phone)
2. Go to DOWNLOAD MODE (Power off ur phone + Volume down. Volume up then. - Take a look how is the KNOX)
3. Install Kies (if ur phone use android 4.2.2) or Kies 3 (android 4.3 or superior) and take a look if all is ok ( Important see what CSC u use). Only making a factory reset solve the problems sometimes(Settings > Accounts > Back Up and Reset > Factory Data Reset > Reset Device > Delete All/Erase Everything). If this dont solve ur problems, follow the next step
4. Your seller installed one custom rom maybe. If all is ok in the step 3, you can update ur phone by there officially. If no, you will have to use ODIN and flash new stock rom.

My device t-mobile SGH-M919 Stock MDL JellyBean4.2.2
Good Lucky

WIFI won´t connect after manual update to Kitkat 4.4.2

Hello everyone, i'm a new member. I apologize if my english is not good enough.
After been driven insane by one pre-installed app from my Operator (Claro Peru) i decided that it was time to root my device to get rid from that pest. I'm a noob, so i started to investigate about the safest methods to not damage my phone. My Device's model is SGH I337m.
The plan was to update the FW from JB 4.3 that came with my phone to 4.4.2 and then proceed to root. I downloaded the Canadian 4.4.2 FW with build version I337MVLUFNC1 and installed manually with Odin. After the phone rebooted, my S4 was upgraded with 4.4.2 but Samsumg keyboard was going insane, so i went to the apps and solved that cleaning the cache/data. Then i noticed that the Wifi wasn't connected, i tried to turn it on, but then a message with a shield appeared saying that my device security stopped the operation. Beliving it was only a problem with KNOX, i installed autoroot (CF-Auto-Root-jfltecan-jfltevl-sghi337m) with Odin, open SuperSU and stopped it from working, but the Wifi still wouldn't connect.
So the first thing that crossed my mind was to unroot and do a factory reset, didn't work. The FW still was 4.4.2, so i´ve been searching solutions with this FW because i've read some cases of devices that stopped working completely after trying to do a downgrade. so i don't want to go to that route for now.
After a couple hours of search, some solutions i found on the forum were:
- Install Faux123 Kernel (Found on Youtube, this would be the thread i think http://forum.xda-developers.com/showthread.php?t=2273437http://forum.xda-developers.com/showthread.php?t=2273437
- Flash a modem for i337m
- Safestrap recovery and bypasslkm.zip
- Downgrade
I haven't tried any of this methods because i dont want to get into a deeper trouble. In the first solution i'm not sure what to do because this is the files the author recommends for canadian models (i337m), but when i enter here http://faux.romhost.me/jflteatt/jb42/http://faux.romhost.me/jflteatt/jb42/ only jflteatt appears, and that would be i337 model, isn't it? I thought that installing it may cause more troubles, so i didn't do it.
For the flashing modem method, i'm not really sure if installing a modem from another country would get me in trouble, so again i didn't proceed.
I found the Safestrap and recovery method on a downgrade thread for the i337, so again, didn't do it.
So, is there a way to get one of this methods working on i337m to get wifi working again, or is there any other better method to get back wifi.
I would really appreciate any help you can give me guys.

ok so you have the i337m canadian version... making anything related to safestrap and the att i337 irrelevant, completely different methods so don't get them confused lol
you were updating from stock 4.3 right? your best bet is to factiry reset and reflash stock fw for 4.4.2 before you brick your device... kitkat is very different from 4.3, maybe read up on it a bit too...
for ex, the "message with a shield appeared saying that my device security stopped the operation" isn't related to needing to root, it's an option under security settings.
to enable superuser on kitkat you need to enable developer options, then enable superuser. I prefer supersu so manually install that from play store afterwards. I recommend checking and/or enabling this as soon as the phone completes booting up after flashing.
also I think there's a known issue w/ 4.4.2 and wifi not turning on until after 2nd boot completed if I rememebr correctly, been using 4.4.4 for awhile now though so could be wrong...
good luck and check out the help section :angel:

No cellular network after installing CM12.1 on Straight Talk SM-G900F (klte)

I recently installed TWRP and then the latest snapshot of CM12.1 for my phone described in title. The android version was upgraded from KitKat (4.4 I believe) to 5.1.1. Everything works fine with the install except I have no network whatsoever. Can't text, can't call, can't use data etc. I made a post on the CM subreddit but didnt get a lot of help (can't post link) . Here is what I have tried: changing APN settings (which I have heard should at least let me call and text if incorrect); flashing various modems such as BOE3, BNL9, and BOD3 (all of them get a FAIL! (auth) in ODIN); restoring my KitKat backup (makes the phone unusable); trying to flash the default L rom for the phone (Also fail to flash in ODIN and TWRP). So at the current time I am basically stuck on CM12.1 and all of its amazingness with no phone functions, I basically have a small tablet at the moment lol.
Here is some information from the about of my phone, if it is helpful at all.
Model: SM-G900F
CM Version: 12.1-20151204-NIGHTLY-ktle (Installed the nightly after the snapshot didn't work, same problem persists)
Android version: 5.1.1
Baseband version: S902LUDU3AOG2
Carrier: Straight Talk
If any more info is needed, just let me know. I appreciate any help, as I am pretty much at square one still. I have googled for days to try to fix this, and haven't come up with anything. It seems no one has had this specific problem before.
If I can't fix this issue, is there any way I can downgrade back to what I had to begin with?

I only have one other sim card on me, and its through verizon. It didn't work on the phone either. I would definitely just buy a new sim card if that would mean it would work. The whole IMEI thing worked, but I am not sure what to do with that information.

(Definitely a G900F? Check what it says in download mode)
Checking the IMEI was to make sure you haven't wiped/corrupted the EFS partition, which contains the Radios needed to make and receive called, along with the IMEI (Hopefully you researched enough to back that up before messing with the phone)
Try flashing another stock ROM with ODIN 3.10.7, go for a different Lollipop ROM from sammobile. com
Some stock ROMs fail to flash, some work, (Phone dependant it seems)
Then boot into recovery and factory reset > try to boot

I have tried 2 separate L roms for the G900F. It says in download mode the phone is a SM-S902L and I read somewhere to get the true model of the phone you look at the FCC id under the battery. Well the FCC id says it is a G900V. at one point in trying to fix it, I tried a stock L rom for the G900V and TWRP told me that it was intended for a kltevzw device and that mine is a klte, so that is why I assume that it is in fact a G900F. I have been using ODIN 3.10.7 to flash everything as well. (Have't tried TWRP for the most recent tries since it takes longer to setup and I doubt it would work but it's worth a try I suppose.
I looked on Sam Mobile for the SM-S902L and there is only one firmware for it, which is 4.4.2, the same one it was installed with when I got it. From my understanding SM-902L is the straight talk branding of the G900V, and trying to flash that firmware didn't work either. Every time I try to flash something it terminates with a FAIL! (auth). What I also understand is that Straight Talk has not released an official version of L for the phone. So it seems my options now are to somehow get the modem to work right in CM12, try to somehow downgrade to 4.4.2, or wait for Straight Talk to release an update for my phone which is not really an option. I just got this phone and I really don't want to have to buy a whole new one just because of software problems. In my mind there HAS to be some way to fix this.
EDIT: my bad, I should have mentioned when I tried to flash the G900V rom it was also CM12, not a stock.
EDIT AGAIN: I seem to have fixed this problem. I have no idea how I did it, but I finally got it to restore to the stock 4.4.2 rom. I seriously have no clue how it worked but it did. Texting and data once again work, but i am now having a problem where I can't make or receive calls. Call immediately ends/goes straight to voicemail. I don't suppose you know anything about that, if you do that would be awesome. I'm gonna call ST in the morning and see if they can tell me anything from their end. But otherwise, I guess my problem is solved. Lol.

I know it sounds simple or may sound stupid but have you tried entering your APN? I have to do that with most of the custom Roms I flash or I won't have service. Also, make sure the correct modem is flashed and up to date.

All I want is a reliable stock ROM :(

Hi all,
very new here and to flashing ROMs etc.
Anyway, bought a 2nd hand Note 3 a couple months ago. It had a custom ROM on it and I was experiencing issues with it.
I've since (after Google taught me), managed to get a close to stock ROM on it. But sadly Im still having problems, mainly WiFi and Bluetooth not working.
Can anyone please recommend a reliable, stock or close to stock ROM?
I dont need anything fancy...I just want to be able to use standard features (mainly WiFi).
Thanks all

I've been using the music of life note5 port 5.1.1 touchwiz rom for months and that's been fine for the most part. darkera13 released a s7 6.0.1 port like 2 days ago on the samsungvn forum, it's buggy but usable, but it's second version are sure to fix the little bugs it has (battery life is bad, can't access sd in pc, other bugs that don't affect me). There is one 6.0.1 s5 port here but I haven't tried it. If you really wanna try the latest touchwiz 6.0.1 rom, wait a few days/week or so for a more stable version, otherwise I'd try one of the 5.1.1 note5 ports in here.

Flash a stock rom from sammobile or samsung-updates via Odin .

Have tried installing a stock ROM from Samsung Updates but still no Wifi or Bluetooth. Starting to wonder if its a hardware problem. WiFi etc does work sometimes, but then goes off for days at a time.
Really frustrating.

Could be anything. Even hw fault... Could you be more specific about:
What custom rom you had?
Is there any chance you had deleted something from efs folder?
Can you activate wifi and doesn`t find networks or the toggle is grayed and can`t do anything?
For bluetooth, can you activate it and doesn`t find devices or the toggle is grayed and can`t do anything?
Try this from sammobile.

Thanks, Im downloading now and will test it out.
Im not 100% sure what ROM it was as I didnt install it.
I do remember something about CM12 ?
Cant activate Wifi or bluetooth at all. It will try and turn on for either but fail and then grey out temporarily.
Ive only installed a custom ROM and havent done anything with an efs folder.

Could you please check if yout imei is there:
In stock rom it is in about device -> Status
Do not post the numbers here just look if the numbers are there

And all other too ?
Like serial number or so
Anyways I recommend you the following:
Download official kit kat firmware xxugng1 and latest lollipop firmware for your country
Do a factory reset
Flash kit kat with odin
Do again a factory reset (just to go sure)
Reboot and do the setup
Root it with cf auto-root
(If phone takes too long to boot remove Battery and start you phone)
When phone is booted Download triangle away
Launch it and reset status and counter
Than it will ask you to reboot or boot in download mode
Choose boot in download mode
Flash latest available lollipop for your country
Factory reset
And than you should not have any problems
(Do backup before it will wipe everything in your phone)

Check correct IMEI.
Check correct modem s.
Check CSC.
Try another kernel
Could well be that you have the wrong IMEI .
I would be restoring my backed up EFS folder first .

If you had a TWRP backup of your previous rom, you wouldn't have been in this predicament.
Try updating baseband version.
Your safest bet is to download Samsung firmwares from 4.2 - 4.4 and 5 & flash it via odin in consecutive order and check if your hardware works.
Or else it might be a faulty HW issue.

A twrp backup would not necessarily fix the issue if it was a hardware problem and it sounds like it is a hardware problem if flashing the latest stock rom does not resolve the issue.

Your safest bet is to download Samsung firmwares from 4.2 - 4.4 and 5 & flash it via odin in consecutive order and check if your hardware works.
Or else it might be a faulty HW issue.

I never made a back up as the phone came with a custom ROM that started playing up within days of getting the phone.
Am trying to find the earlier firmware versions to download now.
Thanks.

A twrp backup would not necessarily fix the issue if it was a hardware problem and it sounds like it is a hardware problem if flashing the latest stock rom does not resolve the issue.

Im really hoping its not a hardware issue as according to 2 local phone repairers its not worth fixing

Check correct IMEI.
Check correct modem s.
Check CSC.
Try another kernel
Could well be that you have the wrong IMEI .
I would be restoring my backed up EFS folder first .

IMEI matches my phone, as does serial etc.
Whats the CSC please?
Current kernel is listed as 3.4.0-4540543.
I dont have a backed up EFS folder unfortunately.

And all other too ?
Like serial number or so
Anyways I recommend you the following:
Download official kit kat firmware xxugng1 and latest lollipop firmware for your country
Do a factory reset
Flash kit kat with odin
Do again a factory reset (just to go sure)
Reboot and do the setup
Root it with cf auto-root
(If phone takes too long to boot remove Battery and start you phone)
When phone is booted Download triangle away
Launch it and reset status and counter
Than it will ask you to reboot or boot in download mode
Choose boot in download mode
Flash latest available lollipop for your country
Factory reset
And than you should not have any problems
(Do backup before it will wipe everything in your phone)

Yes, serial etc all match.
Just looking at the baseband and the build numbers. Should they match? As mine dont.
Baseband : N9005XXUGBOJ1
Build: LRX21V.N9005XXUGBOK6

No they should not match .
Modems/ baseband are often a different build .

Did wifi ever work properly? If not, it may not be worth fixing.
The easiest solution may be to find another phone that has a smashed screen nd swap motherboards.
