unstable GS4 with any rom - Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot

I have tried several ROM - Sacs, TriForceROM, and then I even flashed the NAE modem and tried Negalite. All of them are unstable on my phone. Things lag really bad just switching from page to page. WiFi is unstable, going fast one second then slowing down to a crawl.
I am currently downloading UnknownForce's stock rooted NAE to try it out. I also haen't tried a different WiFi network, only the one at my house - my wife hasn't reported it acting weird for her iphone though, nor have I on my computer - I'm going to try my S4 on wifi when I get to work to see if it's the same on that network.
Basically my S4 has been unusable to me. I've been using my Moto X instead... any suggestions?
I can't help but thing I messed up somewhere like with the firmware or something. I've been thinking about taking into the store and flashing it back to complete stock and starting over.
Thanks

And yes. I did wipe everything including system before flashing the different ROMs

Update: I flashed unknownforces stock rooted and now it won't boot. I flashed it again for good measure and dissable the recovery flash and it's still not booting.

Try odin back to stock depending what firmware you are on.

I'm on NAE. If I do that it will add Knox correct? Would Knox show immediately that it's been custom flashed or only after the next custom flash?

Why the hell do you care if it adds knox? If your phone is unusable and you want to fix it then a clean flash is the way to go. Download the full tar file for NAE from Random45's thread in the development section and flash it in Odin. Problem solved, your phone will work great. Reroot with CF autoroot if you want. Yes, the Knox warranty flag will be tripped but that means nothing. You've already voided your warranty as soon as you installed a custom rom on it, you just won't be able to hide it from Samsung now. Knox does nothing to your phone to prevent you from using it or customizing it. All the posts about knox preventing me from doing this or blocking that are from users that don't know what they are talking about. Just fix your phone already.

The reason I was asking that was because if it still goes crazy then it would be something hardware related. At that point I would be going through Samsung for warranty coverage.
I will flash it back to stock. seems like my best option at this point.

A little confused now since all this 4.3 update talk...

I'm on stock MF9 now. But would like to return to Cyanogen or Negalite 4.3. Can I still do this? Do I need to do something different now when I root, install recovery, and then the ROM?
You got to ODIN the MJA Firmware.

For Cyanogenmod, you don't have to do anything. Im not sure about negalite.
Once you go on 4.3 you're stuck there the bootloader is locked, but you can root. Although you will trip the Knox warranty and void any warranty you have and the only way to get a phone if something happens is going to cost the deductible. .so before you do anything. ..make a backup

[Q] Does reinstalling stock firmware trip knox on Note 3?

I have a phone which has a lot of problems after the KitKat update.
Now I want to try to reinstall KitKat. Samsung doesn't provide this, so I want to use ODIN and the firmware from SamMobile.
Does anybody know if I will do this that it will trip the Knox counter?
What if you try to just reset the phone to factory settings? I wouldn't know anything about Knox though. Hope you sort it out. :fingers-crossed:

I reinstalled my firmware and I can confirm that it indeed won't trip Knox.
As it might be useful I also want to share that updating using my Mac (with VMWare for Windows) gave me a lot of troubles. After using a native Windows laptop the update went fine.
Too bad it didn't solve my problem. Going back to the store to claim my warranty.

So forgive me if I'm asking a stupid question here but I thought that if I root my Note 3 I will automatically trip the Knox counter, even before I get anywhere near flashing a new ROM - stock or custom. Is that not true then?

You won't trip Knox if you install a KK rom but will if you try to flash bak JB.
Any form of rooting will trip Knox. There used to be safe ways that didn't but with the introduction of the newer bootloaders this is no longer guaranteed...
Have you tried backing up any info you want to keep to a pc then factory resetting, I found KK was a b!tch until I reset it due to old JB data scraps causing issues...

I'm on stock 4.3 and not having any issues at the moment - other than my Note 3 not picking up the 4G signal on 3 for some infuriating reason.
So can I flash a stock KK rom without rooting then? I'm probably being thick but thought you had to be rooted to flash any kind of ROM?

You have to be rooted to flash the custom roms provided here and that will mostly be thru recovery. It will surely trip knox. To flash stock roms from sammobile you don't need root. That can be done thru odin.
Sent from my SM-N9005 using XDA Premium 4 mobile app
I would suggest however, if you are network locked to unlock 1st... If you need to flash a separate modem afterwards this can trip Knox as you aren't really using a "Stock rom"...
Also make sure re-activation lock is OFF.... If you go to Kitkat and you don't have a KK rom yet you are stuck with a softbricked phone until you do get the KK rom... You can't go back to JB after flashing KK rom due to a new bootloader...

[Q] OTA 4.4 back to 4.3

Can someone help me take my S4 back to 4.3? I got the OTA update for 4.4 yesterday morning and have had nothing but problems. Terrible battery life (40% down in 3 hours with little to no use) WiFi wont turn on thanks to this piece of junk Knox software. So before I dump Samsung completely for a Moto X or Nexus, can someone help me downgrade from 4.4 back to 4.3 where I had no problems?
Were you totally stock before the OTA? If you still have warranty left, I would bring it in to a Sprint store and *****.
If not, you can try one of 2 things. 1) flash the NAE tar file using odin to see if that fixes your issues or 2) flash the MK2 tar file to bring you back to 4.3

I went Cyanogen at one point, didn't like it, and flashed back to stock. When the OTA hit I was rooted but had made no changes from stock, not even an uninstall of a Samsung app. I am backing things up now to flash the NAE again, but I want a version without this Knox garbage in it. Is there such thing?
I read that you can't flash back with Odin from 4.4 to 4.3 so I don't know how to do option 2 at this point.

Yeah, I think you are right. Can't go back to 4.3 once you have the 4.4 bootloader, my bad. I wonder if you should do a factory reset to see if that clears up your issues.

I believe once KNOX Bootloader has been installed, your stuck with it. No going back.
But honestly, if you root 4.4, your gonna void KNOX.

You can still have all that. KNOX is just the warrantly flag I have KNOX on mine, but I still have rooted and flashed other roms.

You're saying your bootloader went back to MK2 after this? Didn't think that was possible. I've had nothing but stupid little issues myself after using Odin to flash the phone to NAE. I've done factory resets... Completely wiped the phone in Philz. Tried KToonsez kernel as well and stock NAE just sux! I'll probably just flash Liquid Smooth back on it, was only trying to stick with stock NAE for stability and camera , that phone is my girls and she doesn't have the patience for all the bugs that come with custom Roms lol
Anyways just want to confirm that with you. Thanks

I don't know if that is possible for those of us rocking triband. Obviously we cannot use the Mk2 modem or rom. In any event, I upgraded to 4.4.2 on my new L720T and regretted it, but now I'v" managed to install twrp and rooted it and the rom settled down after a few days. At first, horrible battery use but now its amazing. My battery reads 75 percent after 14 hours and that's quite good enough. The only issue I still face is the SD card thing, but that only seems to apply third party software as I can move files directly from internal to external memory using the stock files app that comes with android.
i dont know about triband. i dont have one and im not going to pretend im a smart dev because thats also not true.. i HAVE ODIN 4.4.2 THEN turned around and ODIN 4.3 due to something i didnt like...im not sure if it changes the bootloader or not, i dont even check. i have only tried this with mk2 to nae.. when i purchesed my device it came with mk2 so i have never tinkerd with the other bootloaders. if you have something other then mk2 id ask a dev befor doing anything. like i said it works for me as long as i flash the modem FIRST that corrisponds to the build. ( mk2 or nae )...and in some cases if the wifi is borked on nae, iv had to flash the modem again after instalation of the rom.. i cant explain why any of this happens....

Lol I know what you mean... Sometimes things just seem to work or they don't.
But that's interesting you can go back to mk2 after being on nae. I figured that was not possible. But if you didn't get any fails in Odin while downgrading that's great. Maybe I'll get ballsy and try this later.

[Q] Is Supersu The Best Way To Unroot When Flashing Firmware Isn't Possible?

I need to be able to unroot my phone so that I can take it in for repair.
Apparently my phone (SGH-I337 - AT&T) cannot have firmware flashed to it in order to unroot it (apparently because I allowed an update to be installed a while back when I shoudn't have).
There's a lot of people recommending SuperSU for unrooting but the recommended procedures vary (primarily when it comes to which files you should manually delete and when exactly you should delete them) and there's also no mention of whether or not all traces of rooting are removed.
I'm really worried that I'll bring the phone in and they'll find something which indicates that the phone was rooted.
Note: I don't have any custom recovery or firmware installed. The phone has only been rooted using towelroot. Nothing else.

Wow, thank you very much for that info.! I really appreciate it.
Every set of instructions I had come across told me to flash either the I337ATTAMDL firmware or the I337UCUAMDB firmware, and attempting to flash either of those resulted in a FAIL in Odin.
Before I proceed, can you confirm that flashing this NB1 firmware will not trip KNOX or affect a flash counter (requiring a reset with TriangleAway)?
Also, real quick while I have your attention, do you happen to know of any custom firmware/ROM (eg, a version of CyanogenMod or something similar) that I can flash to my phone? Or am I completely out of luck in that department?

[Q] May have bricked my phone; confused at this point.

So, I was on the journey to rooting my S5, and I seem to have run into a block in the road.
The issue: My phone gets stuck at the 'Samsung Galaxy S5' screen when being rebooted/turned on. After sitting there for a while, it goes into recovery mode.
The cause: In order to root my phone using Towelroot, I was told that I would have to flash my OS back to 4.4.2 (it is currently up-to-date). When I tried flashing it back using Odin, the transition was a failure. I was then told that I would need to switch my kernel to the ncg version, which I proceeded to do by following a guide on these forums, also using Odin. Odin said that the transition was a success, but now my phone won't turn on and I am being faced with the aforementioned issue.
Am I screwed? I'm assuming that I'm not, seeing as my phone definitely isn't hard-bricked. How can I fix this?
Thanks in advance for responses!

There is always a possibility of root in the future but as of now, no. And no, you can't go back. S5's aren't worth as much as they were. I, personally would sell this on swappa and then buy one on swappa with a different build.

Where could I find the stock firmware? I already downloaded what I thought was the stock firmware, and Odin said that the flash wasn't successful. I've tried downloading the most recent OE1, and 4.4.2, and everything just shows up as a failure.
