[Q] Need serious help to safely restore i337 to stock everything - Galaxy S 4 Q&A, Help & Troubleshooting

I received a new phone since I broke my old GS4 (I337). It was on AT&T 4.2.2 and I rooted it using motochopper. It was fine. It automatically updated while I was asleep to 4.4.2. I had rooted my old GS4 on the same update. So I figured I'll just root it again. So I used the method where I flash the NC1 kernel, use towel root, then flash NJ4 back. Now my WiFi will not turn on, but I do have root access. Also, a message saying "Unauthorized actions have been detected" and it tells me to restart to undo these changes. I don't want to do it in fear of bricking my device. I'm really scared now and I desperately need to fix this. I just want to go back to complete stock 4.4.2. I've tried reflashing the NJ4 file twice and WiFi will still not turn on. I've attached pictures of the notice and my device info. Please help. I cannot brick this device. I will answer to any questions as fast as possible. At the moment, I am debating whether or not to flash this because I am unsure if it will be compatible.

Bricking is almost impossible. So stop stressing out. You are in the wrong forum.

Usually you have a wrong modem flashed or something with that problem. Stop stressing out and take your time to find the solution. You will not brick it.

[Q] Having a problem with S4 "soft bricking"

Hello,
I recently tried to root my AT&T Galaxy S4 and install cyanogean mod on it. I screwed something up along the way but I'm not sure what. I tried rooting my phone with Kingo Root Tool, which it said I was successfully rooted. I made the mistake of then accepting an OTA, and of course that soft bricked my phone. I am able to get the phone out of soft brick mode by taking the battery out and putting back in, then entering download mode, and cancelling out. That fixes it every time. As I'm on android 4.2.2, and I understand that I need 4.4.2 for CM11, I thought that I would un-root using the tool, and then try the update again. I un-rooted, it said that it was successful at this. I then tried to install the OTA again, unfortunately it softbricked my phone again. I reset it back to normal, then I figured my best option would be to try and do a factory reset. When I tried the reset, it once again soft bricked my phone. I've reset it back to normal, and everything is working fine, however I'm a little confused as to what's going on. My amateur assumption is that by rooting, it tripped some file rooted deep inside the phone, and now it knows that I tried rooting, therefore it'll block me from updates. If someone could help me this, and possibly help me try and fix it I would really appreciate it. Thanks in advance.

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:

[Q] Lost wi-fi when going to 4.4.4 from rooted 4.42- can't get it back

I rooted to 4.4.2 and it went fine- then I realized I had lost wi-fi.
I have tried to restore and tried using odin and zip files to install a stock rom after I found a similar problem with link on
Sprint forums saying it will fix the ""button won't stay on" but the fix only works if the device is in stock rom.
answer on Sprint forum says baseband version was mk2 needs to be nae.
Return the phone to stock, run the fix for the wi-fi and then re-root.
I have downloaded and ran several roms that say they are stock- I've factory reset, cleared cache, no matter what I do,
I end up with a rooted device in 4.4.2 and no wi-fi. If I could just get the wi-fi back I would take it at this point
This was just a little quick upgrade that turned bad and long
The Sprint forum had a link to get it to nae, but wont work if rooted., so need to put the phone back to stock- run the patch and then can upgrade to kit kat again
TLDR: I cannot get my Sprint s4 back to any version that isn't rooted. I have tried several (lots) of roms that say" stock-unrooted" rom,
Never goes back to stock- stays rooted without wifi-
Ran a rom VPUAMDC_L720SPTAMDC_SPR but when I install I get msge "ifooter is wring signature invalid" - and it fails.
reformatted the sd card, tried different roms and get some message and it stays rooted and no wifi.
TLDR: need to get stock rom so I can get back wi-fi and then root the whole thing. as 4.4.2 Or 4 , if it exists)
Any options and any ideas as to where or what to do?
EDIT: for clarity cause I am not making much sense at this point
Thanks
Heh... a TL;DR for a TL;DR... the internet is becoming one crazy place.

Maybe a dumb question, but why not just unroot first, then?

[Q] T-Mobile Galaxy S5 Root Lost After Phone auto-updated

Hey Guys, I'm brand new to these forums, and to this whole community so bare with me.
Basically I bought my T-Mobile Samsung Galaxy S5 phone around the time it came out, and I also had installed root on it via towelroot when Towel Root was first released. I did not update the phone at all for a long period of time and everything was working fine, until one day I was browsing under settings and accidentally tapped the "Software Update" button, then T-mobile auto-pushed an update onto my phone.
This update has caused the root on my phone to not work at all (Deemed useless) So I clicked SU and only a black screen popped up when I tried to open the app, so I uninstalled it, reinstalled it then got a message saying "There is no SU binary installed, and SuperSU Cannot install it. If you just upgraded to Android 4.3 you need to manually re-root your device" So I tried to re-root via towelroot method again. It seems the T-mobile update made my phone "Unsupported/Uncompatible" with TowelRoot's obsolete techniques, so now I'm in dire need of help.
My phone tried to push another t-mobile update (This time to upgrade to Lollipop) but it failed after attempting to install it after a reboot. So not only will my phone not update to Lollipop, but I'm not even rooted anymore and am unsure on how to get back rooted, or what to do next since I used rooting as a primary source to store apps on my SD Card. Kind of like i'm stuck in one spot? (Can't update your phone/can't root it the old method)
I'm brand new guys, Please can you break down to me what I should do, in order to obtain root again, and possibly be able to upgrade to Lollipop As well as prevent further pushed T-mobile updates? Here's some info if you need it
S5 Model Number: SM-G900T
Android Version:4.4.2
Kernel Version:3.4.0-262.. etc. (Tell me if you need the full kernel details)
Any help would be greatly appreciated! Thank YOU!
Flash this with ODIN

(Will trip KNOX and void warranty)
Or flash a pre-June 2014 KK Kernel, root with Towelroot again, then flash back your current Kernel
Is this the only solution? And also is it the right one? o.o
Can anyone else please give me some feedback on the situation? I want to make sure I do this right, please just a little helps.

Hey I did exactly what you said and it worked I got root back, but I was wondering how to flash back to my current kernel and keep Root?

GS5 verizon 4.4.4 to rooted marshmallow

I have a Verizon GS5 that has been towelrooted on 4.4.4 for close to 2 years. It's worked ok, but I've started seeing various issues that required a factory reset. Since I'm back to no settings, I was thinking updating the OS would be a good idea. I would like to move to either Lollipop or Mashmallow but it looks like the latter may be a problem with my phone (CID 11 and Verizon) while keeping Knox 0x0.
I'm having a problem following the guide that I've found here:
https://www.androidinfotech.com/2016/07/root-samsung-galaxy-s5-sm-g900v-verizon.html
The issue is that I can't get the phone to connect to my PC for Kies or ODIN. It fails to load the MTP driver for my GS5 but works fine with my wife's GS5. Hers is stock Lollipop or Marshmallow and mine is still on JB but is rooted.
I guess what I'm wondering is what my options are. Should I remove root so that I can hopefully connect to the PC to transfer the files over and updating? Or, is there something else I should try first? I haven't worked on many phones and I'm a little nervous about doing something irreversible at this point. I don't know that I need Knox at 0x0, but since I can't get back if I trip it, I'd rather not trip it.

Try to dial *#0808# in the stock phone application.
You should see a menu with several options.
Select "MTP+ADB" under USB settings and press "OK".
Then you'll be able to connect your phone via MTP or ADB to your PC.
If there's no menu, then (assuming you're rooted) open a good file browser (ES, Root Explorer or something) and open the file /efs/carrier/HiddenMenu (it's a simple text file) and replace OFF with ON there.
Save the changes and reboot the phone.
Now the menu should be operational.
Unfortunately, I already tried to update to 6.0.1 so this very helpful info is a little to late.
I followed all directions on the linked page above but didn't get things working. I repeated 2 or 3 times now and I'm clearly missing something. I can get through installing busybox, but then when I reset, it hangs at the samsung screen and just vibrates 3 times repeatedly. I'm going to have to figure this out tonight as I don't really have a backup phone.

Currently root is impossible for MM on G900V CID11.
Impossible means you cannot gain it now, most likely it's forever.
There's no internet site which can help.
You must choose: root on LP or unrooted MM.
You must decide if you want a stock ROM or something (TW-based) else too.
It's a good idea to flash and use a stock firmware for the time while you're thinking.
Interesting... I guess I must have been reading things wrong because I thought I could go to MM with root. I'll try going to Lollipop then but first I'm going to just flash back to JB 4.4.4.
I downloaded 4.4.4 from Samsung and was going to write it with Odin, but it says FAIL when I try to flash. I suspect I just tripped Knox...
SW REV CHECK FAIL : [aboot]Fused 2 > Binary 1
I'll look around to find a guide, but if you have a suggestion, I'd certainly listen!

This means that you've upgraded your phone's firmware while experimenting.
Now you cannot directly flash 4.4.4 with Odin, you're limited to 5.0 (BOK3) and above.
Ok. I'll read the guides on the head of this list and see if I can find the right information.
FWIW, I was following the same how-to that most of the stickies point to and say is safe. I wonder how I got to a position that I'm in now when I did the same as recommended. Painiac's thread points to the same thing I did:
https://forum.xda-developers.com/ve...al/guide-painiacs-essential-guide-to-t3319848
I think I may have tried to flash a MM stock rom though when it got into a boot loop. I suspect that would be the issue.
Bootloop is not a problem in this case.
Just reboot to the recovery and perform a factory reset from there.
The phone will boot but the first boot will take 10-15 min.

Marshmallow can not be rooted on CID 11 devices. The Samsung drivers are found here: https://www.samsung.com/us/support/owners/product/galaxy-s5-verizon You can follow the 5.0 root guide here: https://forum.xda-developers.com/ve.../testers-required-easier-root-method-t3561529 to downgrade to 5.0. If you want to downgrade past that to a version lower than 5.0, you will still have to follow that guide then follow the instructions here (I recommend you to follow the root guide for 5.0 above then skip steps 1 and 2 on this page): https://forum.xda-developers.com/ve.../guide-downgrade-to-kk-nk2-ncg-mm-lp-t3686858 . You can find stock firmwares here: https://forum.xda-developers.com/showthread.php?t=2784880 (stock firmware, kernel, and modem files) and if you get bootlooped or bricked, just reflash the combination file from the root guide. If you want to root 4.4.4, follow the downgrade method using all of the NK2 files but the flash the NGC kernel, run through the setup, then use towelroot and flash the NK2 kernel after that. If you ever get stuck on the red Verizon screen, just pop the battery out and reboot.
That's about all anyone can do and a run down of everything.
Thank you for posting specific guides. I'll go back to step 1 and try again. The primary issue I have at this point isn't reading the guide and following directions, its finding the right guide to reduce the number of images I need to download. I'm on 1.5mbps DSL so d/l a 2GB file takes most of a day. I have several that don't appear useful at this point which means I've lost several days.

Understandable, I can't believe it is 2018 and we still haven't invented a way to compress 1.7GB into 1.7MB archives to make life easy on low connections. How is battery life on 4.4.4 and which update of 4.4.4 are you on? I've been having an issue with my phone dropping a percent every 2 minutes on 5.0/6.0. It would be nice find a version to root along with excellent battery life.
The reason I was looking at updating was due to battery issues. I had the phone for around a week before I rooted it (a couple years ago). After rooting, I started seeing immediate battery issues. My wife has the same unrooted phone (currently on MM) and has never had the type of issues I have. I figured the issue was likely a bad kernel and was thinking I'd just update to something newer (LL or MM) to help. I assume a new battery would help since mine is 1-2 years old, but I swapped with my wife's phone and she still gets lots better performance. Once I get this back up, I'll probably buy a new battery for each phone.
So it appears that I must have upgraded the bootloader to a point where towelroot no longer works as was previously suggested. I believe then that I need to follow the second guide to be able to downgrade to a rootable Lollipop version:
https://forum.xda-developers.com/ve.../guide-downgrade-to-kk-nk2-ncg-mm-lp-t3686858
I am downloading the PB1 rom and lolliroot and need to also get a system restore, kernel, and modem. As I said, my connection is terrible so it would be great if someone could suggest which version of restore I should go with. I was going to install Lollipop in the end (that was the original goal). I figured I'd just get OC4 since it's likely to have the least bugs and best performance. If that is a mistake and I should go with an earlier version of LL PLEASE throw it out there!
Ok, I tethered to my wife's phone and am burning her data (shhhh, don't tell her).
I grabbed all of the OC4 files, the PB1 rom, and lolliroot. I think I have everything I need so long as OC4 is a good place to end up.

Here are some files (that I been hunting for about an hour for). Just gonna reference this for future use and anyone who comes across this thread. http://rootjunkysdl.com/files/?dir=Galaxy S5
Nice find!
I have the phone up and running on stock PB1 currently. I'm going to let it sit to see what the battery is like prior to rooting. While I haven't gotten it hooked back up to my account yet nor do I have it rooted, I feel pretty confident now that I'm on the right track. Thanks!
Just to finish out this topic, I have not successfully completed attaining root on 5.0. I flashed PB1 to the phone and then followed this guide for installing KingRoot:
https://androidforums.com/threads/root-question.1120150/
I got the lolliroot files from here:
https://www.androidfilehost.com/?fid=312968873555011514
Thanks to all who offered help!
Qyuck question... I've got my phone working well bow, but there's one issue with apps I'm not sure how to address. I want to use Verizon Visual Voicemail but I can't find it on the Play store. I disabled updates so I wouldn't get the marshmallow update and break root. but, with updates turned off, VVM won't get pushed. Any suggestions?
