Hello all,
I want to return to an unrooted stock rom but just want to check things first before I do.....
If I download the latest stock firmware from samfirmware and flash with odin will I -
1- loose root???
2- be able to restore my data + apps etc using Titanium Backup or do I need root access (if lost) to do this???
3- need to flash anything else, modems etc???
Im experienced with flashing custom roms etc but have never returned to full stock on the S4.
Im waiting delivery of my NotePro 12.2 and am still using my Note 2 for work purposes and want all my devices to be able to talk to each orher as Samsung intended (well try it at least)

#1: you will loose root.
#2: you will not be able to restore apps+data using titanium backup (titanium backup requires root)
#3: you will need to root the phone by flashing a zip file like cf-autoroot.
#4: if the stock firmware you plan to flash is 4.3 you should read up and find out about KNOX first.
Good luck!

I rooted my galaxy s4 sgh-i337 runing android 4.4.2 today using towel root. It is an apk you install and will root any phone with 4.4.2 or lower. Well I tried flashing clockworkmod but when it restarts a message from at&t comes up saying that unauthorize software is trying to install on phone. So I think that means the bootloader is locked. How do I unlock it so I can flash CWM and perform a nandroid backup. Then I want to install custom roms. I know alot of people were looking for 4.4.2 root for s4 so might want to post another thread about towel root. towelroot .com

You CANNOT install CWM or TWRP. You will need to use SafeStrap recovery. Read up about it, as I have the older Loki bypass and don't need/use towelroot or safestrap.
With safestrap you are limited to flashing Touchwiz based roms. You can flash modems. You CANNOT flash kernels.

There's one partially working Google Play edition rom, but otherwise, no.
This makes me truly sad. I was so looking forward to possibly flashing these ROMS and now...I have to get it my time machine and go backwards lol whenever I find the time to figure the downgrading thing out. Sounds to me like I'll be happier when I do find the time.

There is no way going back to the older bootloader. The only way to go back would be to find an older S4 on eBay etc. with the old BL

All the post below are correct except being able to go back to firmware with an unlocked boot loader.. Install safestrap 3.72 and install recovery. You will get a Twrp recovery .. dont try flashing custom kernels ..It might flash but none of the setting such as overclock etc. will work .nor will you be on that kernel version afterwrds .. I guess the simple answer is no for cwm and aosp roms .. You will be only able too flash custom stock roms
Wifi issues with towelrooted gs4
First off this may not be the right place for this (first time poster), and if so, either please help me in finding the right forum or forgive my ignorance.
I rooted my galaxy s4 today, and I have found that when I am trying to use wifi I am unable to connect to some pages. Using chrome I am unable to load google.com, or google anything directly from the search bar. And the app imgur also doesn't load whilst on wifi, but if I switch to my cell network they load just fine. If I had unlimited data of course this would not be an issue, but that is not the case and therefore I come to this forum and hope that someone can help me out!
My s4 is an at&t i337. I would amazingly, greatly appreciate any help!
Much thanks in advance!
lost recovery with unlocked bootloader
Hello,
longtime flasher here, not as familiar with gs4.
My girl has a sgh-i337 that has been bootloader unlocked since day one. Been on TWRP and slim rom the whole time too.
I was wiping Cache, Dalvik Cache, and System prior to doing a rom update and TWRP glitched out while updating partition after the final wipe operation. Screen went black. Boots to download mode only.Will not boot rom (as system was wiped) but shows the samsung custom unlocked logo. When in download (odin) mode, I see product name: sgh-1337, Current Binary: Samsung Official, System Status: Custom CSB_OEM_LSB: 0x30 Write Protection: enable
universal android toolkit will not show device connected so Installation of custom recovery through toolkit fails. ADB will not show device connected. ODIN will show device connected, though.
To recover with odin, can I flash the I337UCUAMDL from sammobile and retain unlocked bootloader?
Thanks for any and all help.
What is the bootloader version you need to unlock? I have 4.2.2 Red ATT S4, Baseband Version : I337UCUAMF3 / BUILD: JDQ39 , if i was able to unlock how would i go about doing so? I was hoping i could do something with Loki if not? How does Loki work exactly as well?
Congrats, you just voided your warranty. It will be 0x1 instead of 0x0.

I've used both CF Auto Root, Towelroot, and Motochopper guides and none of them have worked.
The only file I have on my computer is: philz_touch_6.08.9-jflteatt.tar.md5 as one of the files I used but that didn't work. I actually had already downloaded the files from the article you had linked but I didn't get around to it yet, I'm going to try that method out in about 15-30mins and see what happens.
It worked!

Followed everything on that post and it worked! I'm rooted!
Though I'm not sure if you know about custom recoveries. I'm having issues with installing any of them and having it work. I am currently trying Safestrap and for some reason it won't install the recovery. It'll go through the process, but the state of the recovery won't change or anything.
I ultimately want to install CM11, but I'm really struggling to find a way that works!

I still can't figure how to install the .apk file from kingroot..? How do you install the file to root it..?
Note: Relevant device info will be provided below.
Dear techwizards,
I've been trying to root my phone for a while, I've done it before: both my S II and S III were international variants, and rooting those devices was very simple. But after getting an S IV from America and consensually downloading a samsung issued update -- I had yet to read up on the disadvantages of knox -- my rooting and android experience took a turn for the worse.
Long story short -- I know developers are a proud bunch who value their time -- I tried rooting my phone yesterday after almost smashing my phone on a coffee table. They say it's a well known side effect of Touchwiz, but I'll leave that to you.
I used a towelroot.com root -- a wonderful tool, if I may say so. After that, I visited the CM website and picked out the compatible CM11. I never got to flashing it though, as my problems arose while installing a recovery.
I had downloaded an app, a something recovery or another. They had an option to flash recoveries on there--it would download your recovery for you and do all the work, which seemed plausible as most video tutorials demonstrated. To my astonishment, doing so bricked my phone.
I tracked back, looked for the samsung stock rom, downloaded all 2.2 gb's of it and flashed it. It worked. My phone was functional but I suspect something within it stinks. My device, apparently for security reasons, wont let my wifi or 4g to establish a connection. It's making it impossible for me to fix this problem as I can't root my device or flash a custom rom.
About Device:
Pre problem I was running a:
SGH-I337UCUFNC1 baseband. Build Number ending with: NC1.
Android version: 4.2.2
Post problem:
Baseband: I337UCUFNC1
Build Number: JSS15J.I337UCUEMK2
Android version 4.3.
If I could find my original stock 4.2.2 NC1 version and get simple instructions on how to re-install it back to stock version, I'd be very grateful.
If you know how I could fix the internet issue on the MK2 one, and provide some simple instructions of how to root it, I'd be grateful too.
If you think neither would work, and have something else in mind, Im open to your suggestions.
Much Regards,
Y

Since your bootloader is already locked, you might as well Odin to stock. Odin to NB1 then use stock recovery to flash the NC1 update from a zip file on a microSD.
Part of the problem is that the NC1 is not 4.2.2 like you listed, but 4.4.2. That's the update you applied that started the sordid tale. When you were on 4.2.2, with bootloader MD<something>, you could have flashed CM or whatever, because you would be able to have TWRP or CWM recovery. When Samsung pushed out a 4.3 update (MK2 I believe) all the unlocked bootloader fun was over, probably permanently for this phone.
When you flashed MK2 firmware (4.3) onto the phone, parts of it don't work with the NC1 baseband, causing the problems you've seen. If you Odin NB1, then do the quick zip update from stock recovery to get all the way to NC1, you'll be back to stock and everything should work.
Once that's done, you can go through this process:
1. Root with Towelroot.
2. Install SuperSU to manage root access. (You might have to reboot, it's a 50%/50% shot... sometimes it hangs trying to disable Knox... no worries just reboot)
3. Install SafeStrap... it will create the safestrap recovery. You might need to install SELinux Mode Changer app (from play store) and set to permissive, to get Safestrap installed.
4. Boot to the SafeStrap recovery. Install any touchwiz rom. Only touchwiz compatible roms will work. I liked GoldenEye.
When installing touchwiz ROMs, typically one flashes the ROM, then SuperSU, then the NC1 modules, then the ATT BuildProp/APN file. Sounds complex but goes quickly. Some roms have some of these things built in.
Good luck! I eventually decided I didn't like the ATT Samsung restrictions of the locked boot loader, and bought a T-Mobile M919 variant of the S4. Unlocked boot loader. Woo hoo. And works fine on ATT.

Thanks in advanced!
Try to odin to stock (make sure you get the correct files), root, install SafeStrap following the instructions here: http://forum.xda-developers.com/showthread.php?t=2448942
After that you need to flash the rom, kernel modules (you can get them here: http://forum.xda-developers.com/showthread.php?t=2447764), then after that you flash SuperSU (if you don't have that file then here it is: http://forum.xda-developers.com/showthread.php?t=1538053 DO THESE STEPS I JUST SAID IN THE SAME ORDER LISTED HERE: Flash ROM, correct kernel modules, and then SuperSu.)
If the same error ocurrs then it's most likely the rom just isn't compatible with you device. Also, make sure it's an S4 Active rom not a normal S4 rom.
NOTE: I do not own an Active, but doing some 5 minute research is what helped me figure this out for your device.
Ok, I´ll try! Sorry, but everything I did before, unsuscefully is the result of many hours of forum research......problem is....I don´t know a lot about this....yes, probably shouldn´t mess with it, but truth is I live in Argentina, and wifi + bluetooth stop working with stock rom....no matter how many times I hard reset it so I figured changing rom might solve it........
I went to through the same you're going through with my S4. I ended up flashing the wrong Odin files like 5 times before I figured out what file to flash, lol. Glad to help

after you flash with safetrap, does the kernel have to be flash with safetrap or with Odin? i did root my GS4 using Odin and have the I337_NJ4_Stock_Kernel. can i use that one or do i need to download any other tipe of kernel??
You need to flash the kernel modules via SafeStrap. The NJ4 modules (and other modules) can be downloaded from here: http://forum.xda-developers.com/showthread.php?t=2616221 navigate down to the KitKat Install instructions, look for step 4 (Install ATT Kernel Modules), in the first sentence click the hyper link redirecting you to AndroidFileHost, and then download the corresponding Kernel Modules to FLASH DIRECRLY AFTER EVERY ROM YOU FLASH.
THE FILES LINKED ARE FOR NORMAL S4 ONLY.
Sent from my SGH-I337 using XDA Free mobile app
Those two things are different...
You can only flash the nj4 kernel via Odin using the ap slot. I'm not sure if safestrap can flash kernels, because we're not meant to or we would be using twrp.
The nj4 modules should be flashed along with what ROM you're using during use of safestrap.
I was referring to the stock kernel modules (what I linked him/her to) needed to be flashed after the ROM each time. Also in SafeStrap, can't you flash stock kernels? I'm pretty sure you can. If not then I'm just crazy lol.

You need to use the Stock slot. Any other slot causes errors on most roms, and how do you have two bootloader versions? I'm thinking that MF1 is your BL and NE3 is baseband or something.

Do not use Safestrap...you have an unlocked bootloader and have no need for it.
It will not work well with an unlocked phone like you have as the recovery is designed for locked US based carriers.
I think he means that he's SIM unlocked. I'm not sure they have an unlocked BL for the Active. If they do, then he should go ahead and use TWRP or CWM.

Hey guys,
I've got a G900W8 from WIND mobile, running CM13, and I'm looking to flash the latest modem. Does anyone know where I could download this? Been looking here and there, can't find anything, and I don't really want to have to go back to stock to upgrade and flash again. Could I just restore from that point?
Also.. if someone, via twrp, makes a backup of their G900W8VLS1DPF3 modem, and I simply place that into a nandroid and then restore.. would that work?
