New S4 with NB4 bootloader and Knox, now what?

Hi everyone,

I just received my Tmob warranty exchange S4 and it is on the NB4 bootloader with Knox installed.

My old one, still running 4.2.2 and MDL, has a GPS that just isn't working anymore for some reason so the exchange has to be made. I haven't been keeping up with anything past 4.2.2 so excuse the silly questions (that's what this thread is for right)?

I understand that on 4.4.2, getting root will trip the Knox flag. Right? Oh well, I guess that's okay. I understand 4.3 had a way to get root without Knox trip, but not 4.4.2.

Once I break KNOX, can I flash a custom recovery the same way as before?

Can I flash an older 4.2.2 ROM and expect it to work?
[T-Mobile Samsung Galaxy S 4] Skipjacks:
You can flash a custom recovery with Odin just like you would with any other version. That will trip knox. You don't have to do anything special to trip knox first.

Then yes, you can run a custom 4.2 ROM. You can't run the stock 4.2 rom, but you can run pretty much any custom 4.2 rom.
[T-Mobile Samsung Galaxy S 4] DevoidDroid:
How do you know KNOX is tripped? Is there something that identified it somewhere on some boot/loading etc. screen?
[T-Mobile Samsung Galaxy S 4] Skipjacks:
Boot to the Download Mode screen. Upper left hand corner. It'll say something like KNOX 0x1 when its' tripped. Right now if you look at it it will say KNOX 0x0
[T-Mobile Samsung Galaxy S 4] DevoidDroid:
Rob, worked like a charm. Thanks for the tut! Thanks given!

---------- Post added at 09:37 PM ---------- Previous post was at 09:31 PM ----------

Ah yes. I've seen it. I was hoping that was supposed to say 1x1. lol. Thanks man. I assume triangle away doesn't help here either? Has this been an issue with warranty replacements? I really don't think I'll ever need the warranty, yet I pay for it anyway. Ha.
[T-Mobile Samsung Galaxy S 4] Skipjacks:
Triangle away doens't help. It's not been an issue with warrenty yet.
[T-Mobile Samsung Galaxy S 4] DevoidDroid:
I was under the impression that KNOX was positioned in the market as a corporate security app. It seems like it's geared more to id rooters. Anyway, I'm not over concerned anyway. Any thoughts on Xposed + Gravity Box? I'm thinking I might want to try it.
[T-Mobile Samsung Galaxy S 4] Skipjacks:
What you thought first was right. Its a corporate security thing. It is not being used to id rooters.

I can't get Gravity Box to not force the nav bar at the bottom of the screen so I don't use it. Ex Themer is a good alternative for xposed framework.

Sent from your phone. You should be more careful where you leave that thing.
[T-Mobile Samsung Galaxy S 4] Kevin70707:
By the way guys, my phone does charge when it's off, it just gives no sign of doing so, so I thought it didn't. Thanks for the help.
[T-Mobile Samsung Galaxy S 4] DevoidDroid:
Cool. I'll check EX Themer out.
[T-Mobile Samsung Galaxy S 4] rlichtefeld:
You are welcome. Glad it worked.

I'm assuming the 0x1 is hexadecimal speak for a binary 1.

[T-Mobile Samsung Galaxy S 4] waylo:
Thanks for the quick confirmation.

Tried running with 4.4.2 stock, just in case they come out with a saferoot that works for 4.4.2 in the near future.

After 2 hours, COULD NOT TOLERATE IT! All the apps that allow for 'rooted' function on a non-rooted device are just sad... very very sad. Bloat bloat everywhere.

What moron thought new 'additions' like less SD support for apps was a good idea???

Tripping KNOX now and flashing something decent!

...Question...

On folder Mount. When I link up the folder from my internal to its destination on the external... And the pin is green, it still shows up on my internal and I can use my game. But when it's white, it doesn't take up any space on my internal, and I can't play my game.

However, there is no data transfer time with the pins.

I'm wondering if when I link it and its green... is it actually taking up space on the internal? Or is that fake info? Does there have to be free space on the internal in order for the pin to go green? Or will it work even if the internal is filled up before attempting to link them?

Didn't know where to post this question.

Contemplating getting the S5....
[T-Mobile Samsung Galaxy S 4] leafar1225:
Hey, im kinda new to posting all I ever did was always read but i cant seem to find the answer this time.

My power button broke. Basically it was constantly making the connection so when i took the battery out and put it back in it showed the galaxy s4 logo than shut off which u would expect it to do when u keep holding the power button.

Next thing i tried was taking it apart I, unsoldered the power button and put the phone back together, now I cant turn it on. i thought plugging it in the charger than inserting the battery would work but it just shows that its charging thats all. I was wondering if there is some kinda program that you can boot up the phone through the PC. I am rooted and running a ROM using TWRP i CANT get into recovery but i can get into download mode.

I AM under manufacturers warranty, thank God. But the only thing thats holding me back is ALL my stuff i wanna save everything before i send it in. Please HELP. All my backups are gone except the things i have on titanium backup which was about a month ago.

I know i have grammar mistakes please excuse me.
[T-Mobile Samsung Galaxy S 4] htcp85:
Does anybody know why some folders have date created and modified of 03-22-1970, I did a factory reset and same thing.
[T-Mobile Samsung Galaxy S 4] Skipjacks:
Can you get into recovery by booting to download mode, then using odin to reboot to recovery? (I'm not near Odin so I'm not sure if that's even an option. Just an idea)

On that same concept, could you use ADB to reboot to recovery?

I don't understand why you can get into download mode. How did you achieve this? That might help figure out a way to get into recovery.

You might also be able to take the phone apart again and short out to power switch once to get it to boot into recovery. I had to do that once on another device where the power button failed. I cut the little ribbon cable and uses a tiny screw driver to short it out until I got it to boot.

Once I had it booted to the phone I used the advanced power menu to reboot to recovery. It was much easier than trying to short out the power cable while holding over buttons to boot directly to recovery.
[T-Mobile Samsung Galaxy S 4] Skipjacks:
It's the default date. It shouldn't make a difference for usability. But if that's happening on newly created folders then perhaps your clock isn't working properly. That's just a random guess though.
[T-Mobile Samsung Galaxy S 4] htcp85:
Alright so nothing to worry about, thanks for your help
[T-Mobile Samsung Galaxy S 4] leafar1225:
Haha, i got it!! I got into download mode by plugging it in first, then inserting the battery while holding the volume down button. Right after its simple just hit volume down button aka Cancel (restart phone). After my ROM lets me restart right into recovery from the settings. unfortunately if i had broken volume buttons i would be out of luck. But i still believe Odin lets you somehow reboot your phone via PC because it communicates to the phone using download mode. Anyways thanks for the ideas ;).
[T-Mobile Samsung Galaxy S 4] Kevin70707:
Tried overclocking to 2214 MHz. Shortly after, my phone emits this high pitched whine, really loud. Had to pull the battery out to stop it. Was that a battery temperature or CPU warning? Just curious. Back to 2052 MHz, hasn't happened since.
[T-Mobile Samsung Galaxy S 4] Skipjacks:
Don't know what that was. But I'd never do it again.

Not all processor chips are created equal, even if they are the same model off the same assembly line. Some chips just can't handle being pushed too hard and they fail. Yours clearly doesnt' want to be pushed that hard. So Id never do it again.

The whine wasn't a programmed alarm. It was likely the sound the chip was making from ossilating too fast.
[T-Mobile Samsung Galaxy S 4] Kevin70707:
Thanks. I won't do that again.

So I recently got my S4 to be factory unlocked to a technician so I could switch over to Cricket from T-Mobile. I then rooted the ddevice afterwards, and it was ggoing great until I couldn't get data on CM11 nor SlimKat, so I searched for a fix and it turns out I had to flash the NB4 modem twice. I tried that using MobileODIN and it didn't work, so I tried flashing the stock KK firmware using MobileODIN and it left me with this instead whenever I try to boot the device

I don't know what to do and I'm freaking out. I even tried flashing the stock firmware through ODIN on my PC and I always get an error. I cannot even boot to recovery to do a hard reset Please help /:

Hi there,

I have a Samsung Galaxy S4 with T-Mobile, and I'm wondering what the default SIM PIN is for the "SIM card lock settings".

If you go to Settings > More > Security > Set up SIM card lock;

It'll ask you for a pin before you can change it, however it is a default pin that I have no knowledge of..

If anyone can help, it'll be greatly appreciated. Thanks.
[T-Mobile Samsung Galaxy S 4] rlichtefeld:
As far as I know T-Mobile SIMs don't come with a SIM Lock already turned on. If it is asking for a PIN, then someone has already set one. If that is not true, I would recommend you go to a T-Mo store and have them give you a new SIM, and then when you have it in the phone in the store, test going to the setting.

Hi, so I bought a Samsung Galaxy S4 online and I'm new to this android thing, and I am wondering if I can update it to the new android kitkat, I'm from Portugal, the phone came from Germany, its from T-Mobile but SIM unlocked, it comes with Android version 4.3, I've tried updating but it says it has the latest update, I don't understand German so if anyone could tell me if there will be an update to kitkat later on or is there a way to update it without rooting it so I don't loose the warranty, it would be great.

The phone model is the GT-I9506, I'm not knowledgeable enough to know if a firmware from the GT-I9505 would work, but my guess is a no.

I would leave a screenshot of the phone details but since its my first post I can't just yet, so I'll type it.

[T-Mobile Samsung Galaxy S 4] lalec:
Have you already searched for radio patches and also searched in the I9505 forums? I unfortunately don't have the answer you need but others have successfully gotten phones from other networks to work on T-Mobile (e.g., AWS patch for AT&T variant). Maybe there is something for you too. Also, depending on what area you live in, T-Mobile HSPA+ is in some areas faster and better on battery life than their LTE. Good luck with it.

Also, why not nandroid backup what you have and then try to install a T-Mobile ROM? If it is really the same hardware you should be able to get it to work as long as your ROM, kernel, and radio are all compatible. That is what I would try.
[T-Mobile Samsung Galaxy S 4] jayman350:
I have been holding off on going beyond 4.2.2 because of the SD card support issues, but now I'm getting a lot of random force closes and I'm thinking that its about time to get up to date. I'm still on the MDL baseband and can not find much info regarding updates beyond this. Almost all of the tutorial/walkthrough threads are regarding old builds that no longer apply.

What is my best/easiest bet for updating? I'm not a stranger to flashing ROMs and the like, but the majority of my time has been on Motorola devices (OG Droid and Bionic). I've been getting mixed up with all of the various baseband options, what can be flashed over what, at what point are you no longer able to "downgrade", etc.

Thanks

If you are on MDL bootloader you can visit below thread to update the baseband to NB4.

If you take the official tmobile OTA from 4.2.2 to 4.3 or above you will not be able to go back to 4.2.2 bootloader add the OTA has knox. Also one you have Knox on your device and you root it, you'll trip the Knox flag which can't be reset; it's a permanent thing. Hope all this information helps.

Ok, I'm new to modding phones. I want to flash the T-Mobile Galaxy S4 with the google play edition ROM onto my phone. Do I need root to do this? I've read that you don't need root to flash roms. What benefits do I get with rooting the phone? I know you get Super User access with root but what exactly does that mean? And I've also read the rooting voids the warranty. I'm just concerned that rooting my phone would open my phone up to security vulnerabilities.
[T-Mobile Samsung Galaxy S 4] a103:
You don't have to be rooted to flash a Rom indeed you need a custom recovery to flash a new RoM however almost all the roms are pre rooted so if you flash a Rom you will be rooted.

Rooting has lot of benefits including removing carrier out manufacture bloat ware, installing apps which need root permissions, customizing your phone and a whole lot. Check out below link yourself to know more ☺

Double tap home button to see apps in memory + used/available ram + clear ram button

ROM Switching and Flashing

Alright I am running the Unified version of CM11 running 4.4.3 and I want to switch to the new PA 4.4 RC1 (which is also running 4.4.3). I was wondering if I could just flash it straight over my most recent CM11 instad of having to wipe and all. I heard that if the android version does not change then I really have no need to wipe but am I REQUIRED to wipe. I really dont want to cause I have so much to back up and all. I know I think they are both AOSP (I am probably wrong) and if not does that make a difference. And will my kernel change if so then does that effect the fact I can or can't flash right over. So really I am just hoping I can just flash the new PA 4.4 over the CM11 to get the ROM.
[T-Mobile Samsung Galaxy S 4] Skipjacks:
You can always try it. Just make a backup first for when it doesn't work.

But I'd bet heavily that it will cause problems. Even if it boots, something will be screwed up. Even if you don't notice it right away.

A full wipe with backup and restoring settings only take like an hour from start to finish. Just spend the time to do it properly. It's worth it. And you'll save time in the long run from not having to fix 100 things that didn't update right.

OTA Update from 4.3 to 4.4.x

This is a noob question i guess. I am currently running 4.3 and I have an OTA available for 4.4.x. When I go ahead and update it would there be any loss of data, settings, app/data or anything of that sort akin to flashing a new firmware. Because the steps on OTA advise to backup. Is it just to prevent unforseen errors that may occur during update or mandatory because there may be erasing of certain data if any?

Something wrong when opening apps

Hi guys, I never posted here but am trying to find some help. I've had my S4 for quite a while now, and I just factory reset everything because I kept getting a "Unfortunately, the process android.process.acore has stopped." message that wouldn't go away or let me use my phone without an interruption literally every 2 seconds. But before I even had that problem, there were worse problems as well. There are two things that occur frequently:

1. Sometimes, when I tap on an icon, the indicator light shows up (a glow around the icon), but the app itself does not open. Then, if i tap on it repeatedly, nothing happens. I can temporarily fix this problem by opening up the recent/opened apps list (holding home button) and clearing everything (or clicking on that app if it had been opened). Once cleared, I can tap it again and it would open. As you might see, this can get very annoying and troublesome after doing it so many times. Is there anyway I can permanently fix this so that I don't need to keep clearing the open apps list?

2. Sometimes, when I unlock my screen, exit an app, press the home button, or clear the opened app list (as mentioned above), my wallpaper changes to an app. The app is usually random and sometimes is not one that I had opened. For example, the background of my messaging app or Astro File Manager would show up even if I had not recently opened it at all. I can also temporarily fix this by clearing the recent/opened apps list (as mentioned in #1). After clearing this, the wallpaper resets. Is there any way I can fix this permanently as well?

3. Snapchat and VSCO Cam constantly "stop unexpectedly". I don't know if this is a firmware or incompatibility issue, but it usually works fine. This message pops up once in a while and isn't too burdensome, but is still quite annoying.

Thank you for all the help in advance. I am trying to get the most out of my phone and appreciate any help.
