Because I'm on an older one and various roms keep saying to use the most recent baseband, and I'm afraid my phone won't work as well as it can since it's not on the most recent one.
[T-Mobile Samsung Galaxy S 4] preacherjoe123:
If yours ends in NK2 then you have the most recent one.
[T-Mobile Samsung Galaxy S 4] ben7337:
My baseband is M919UVUEMK2, from what I understand I'm 3 basebands behind.
[T-Mobile Samsung Galaxy S 4] preacherjoe123:
Then reflash the stock rom . it should come with the updated baseband if not check for software updates via settings->about device-> software updates to get the most recent version then reflash the custom ROM. However some custom ROMs come with their own baseband versions I.e. CM Nightly 12.1 which I currently have installed.
[T-Mobile Samsung Galaxy S 4] ben7337:
Can I flash to the stock rom via a custom recovery and then flash over it again with a custom rom once the baseband is updated? I had CM 12.1 on my phone before but I didn't think it came with any new basebands. It's been my experience that AOSP based 4.3 and 4.4 roms drain battery so fast my 5600mah battery can't even get 8 hrs on, and lollipop roms all don't have functional dialers and 3rd party dialers don't work on them either, plus lollipop has very glitchy xposed framework still. I finally found things somewhat work well on stock TW roms and can be reasonably customized with xposed, but none of those roms seem to come with the baseband built in for whatever reason.
[T-Mobile Samsung Galaxy S 4] preacherjoe123:
Yes thats how I would do it. And I have a 2700 Mah battery if I do it right I'll get around 10 hours. Sounds like you may consider getting a new battery.

Warranty

Hello XDA!

I've had my Galaxy S4 since last July. At first I rooted my phone, but then when I realized that the camera quality wasn't as good when I rooted, I unrooted my phone and installed the stock ROM. I used my unrooted phone without problems for a solid 4 months. However, one day I made a call on my phone but the earpiece made a really loud high pitched noise so I hung up immediately. When I restarted my phone after that, I started to have issues. Now it can't restart properly so it gets stuck on a bootloop sometimes either on the T-mobile screen or it turns on then crashes because it can't connect to the network. Also, when I manage to turn it on, music and video don't play and sometimes calling doesn't work either. I tried factory resetting through recovery and Odin, but any fixes are temporary. I contacted T-mobile and my phone's under warranty so I can get it replaced for $20 dollars, but if they find anything wrong, they'll charge the full $400 for the phone. I've reset the binary counter but I heard about the Knox warranty bit and I'm worried that they might charge me the full $400. What should I do?

Thanks. Sorry for wall of text.
[T-Mobile Samsung Galaxy S 4] a103:
This might help to check if you have tripped Knox. http://omegadroid.co/wanted-knox-void-warranty-0x1/

If it's not tripped you can Odin back to stock T-Mobile ROM and reset the flash counter. Ideally going back to stock should resolve all your issues, if it does not then you can return the device to T-Mobile if Knox isn't tripped. I've read people returning devices with Knox 0×1 but that doesn't mean it'll the case everywhere. So it's up to you to decide.
[T-Mobile Samsung Galaxy S 4] BananaAsian:
Thanks for the advice. I have indeed tripped Knox so I guess I can't use my warranty. Do you know if there's any way to fix my issues? The main one that bothers me is that music and video do not play.
[T-Mobile Samsung Galaxy S 4] lordcheeto03:
Ohh, my bad, I read that wrong. I read it as "I've never used CF-Auto-Root, use ChainFire's method instead." I was thinking "lol wut?" Apologies :good:

I had something about not being able to have custom recovery without already being rooted... THEN I read the link in your last post.. :D derp
[T-Mobile Samsung Galaxy S 4] corkythetard:
HA! No worries whatsoever!

Ya, flashing it via Odin is how I installed it. There are links in the thread to the CWM Touch. MUCH easier to navigate, although the font is really small by comparison to other versions I've used. Flash CWM after following all instructions, reboot to recovery, back up to external sd. b00m! :cool:

Hello :( So I recently used goomanager to wipe my internal memory...probably not a good idea correct? Well now that I've done that, my phone is stuck at the "Samsung Galaxy S4" screen and I can't go into recovery mode, however I can go into download mode. That's about all my phone can do. Also it isn't being recognized by my computer :(
[T-Mobile Samsung Galaxy S 4] Irreverence:
i just bought an s4 yesterday off of shopnbc, and it will be arriving next week. is there anything i should do with my phone immediately when i get it/are there things that would be better to do early on? and while i'm waiting for its arrival, what should i look into or read up on? i plan on running some sort of google edition rom, if that makes a difference

this will be my first android and first phone in general so any links/suggestions would be greatly appreciated :laugh: i've already read a couple helpful threads but i know that there's a lot out there that i have to take in. just don't necessarily know where to find it

Thank you. Now, how do i flash the apps from recovery?
[T-Mobile Samsung Galaxy S 4] lordcheeto03:
What recovery are you using? I know TWRP will sometimes hang at the splash screen for a few times before it successfully boots into recovery. I can't speak for other recoveries, just throwing out a possibility. Also, about connecting to your computer, are you sure that you have the correct drivers installed for your phone? If you can enter download mode then there is really no other reason your computer can't see it than you don't have the right drivers. About wiping your internal memory, I'm not 100% sure if it matters or not whether you wipe from goomanager or recovery. I just always wipe internal memory via recovery (on accident, thank you TWRP 2.6) and have suffered no ill effects.

It all depends on what you want to do with it. If you want to root, I'd go ahead and start reading up on the different methods used to root. Easiest and most fool-proof would probably be CF-Auto-Root. If it's your first phone in general, I'd say just play around with it for a few days. If you want to root, I'd make that step number 1. I had mine rooted within an hour after walking out of the store with it, but everyone has different preferences. If you don't foresee a need to root, then don't worry about it. If you want to stay mostly stock, look into some debloating threads; go ahead and get an idea of what apps you won't need or want and whether they will be safe to remove (will require root permissions). If you think you may turn into a flash-a-holic, now would be a perfect time to do some reading on custom recoveries; how to install, how to use, etc. Check out the ROMs. I know it's kinda hard to judge a ROM if you can't flash it, and even harder if you don't have any experience with them, just find one that you think looks good and has features you would be interested in then add it to the list.

[T-Mobile Samsung Galaxy S 4] lethalfang:
Thanks.

I'll probably do a week of reading before taking the plunge.

I've flashed routers before with custom firmwares..... but a router is no more than $100, whereas my smart phone is almost $600, so I'm a lot more nervous about bricking a smart phone. :fingers-crossed:
[T-Mobile Samsung Galaxy S 4] corkythetard:
Definitely read up!! It's kinda nerve racking the first time, but with the n00b proof CF-Auto Root AFTER installing a custom recovery to make a Nandroid back up, you should be fine. As the name of the thread says, Ask Any Question! We're all here to learn. Bricking an Android is pretty tough to do these days. A soft brick is very easily fixed. To really brick it, you have to be unable to read and follow the instructions in the OP(Original Post) of the thread you're reading. If the OP doesn't make sense, read the thread, and if still unsure come back here and ask away! No question is a dumb one here. :highfive:

I was able to reboot it just fine 30 minute before i turned it off. The phone was rooted 1 month ago, and i did not do anything major since. I have a backup done by twrp but i can't boot the phone. Can you guys help me try to fix it

It's on lolipop

Greeting xda. How is everything? I have a Galaxy s4 and the 4g keeps on turning on by it self all the time.I need several attempts so it can dhut down via an app or even from the menu. In addition if the phone reboots the 4g starts to. Any ideas?
[T-Mobile Samsung Galaxy S 4] Skipjacks:
The battery could be fully drained. And the recovery could have errors that prevent charging while powered off.

Do you have access to a second battery or an external charger?
[T-Mobile Samsung Galaxy S 4] Skipjacks:
Isn't that a good thing?

Also look in the network settings. There is a thing in the network settings for preferred network. Select the right option for you.
[T-Mobile Samsung Galaxy S 4] timex163:
Battery is full, I tried it with another phone. Before i turned off the phone, I think they might of been a power surge coming from my incipio off grid to my s4. why ? It went from 75 % backupbattery to 0 % . I then turned it off and put it to charge. Tho when i came back nothing. Phone would not turn on. Battery did not even charge. I also deleted some bloatware like watchon, ChatOn and a few others that i don't remember. I justg want to say that it was able to reboot fine after i deleted those apps 30 min earlier. Do you guys think it's the PMIC chip that's dead ?

Yes, T-Mobile M919 roms work with Metro PCS M919N

I am currently using a Metro branded M919 Galaxy S4. I used Odin to flash the T-Mobile M919 rom and it flashed the first time, no errors, absolutely no issues.

I keep seeing thread with others saying the T-Mobile rom can soft brick or hard brick the Metro M919N but it does not and has not in my experience. I flashed back to Metro PCS firmware when they added battery optimization, but I returned to the T-Mobile as it just runs faster.

Lollipop Update

Hey guys just wondering if I can use the software from the SGH-M919V on my SGH-M919.
[T-Mobile Samsung Galaxy S 4] awdark:
I know this has been asked many times but I must ask again because the software progresses but more often than not the documentation lags behind.

I am on stock android 4.2.2 unknown rooting method but it has root T-Mobile s4. Experienced with old android 2.3 era flashing and modding but really out of date now. Doesn't seem like we flash from sd anymore.

From what I understand the bootloader is not locked on the 4.2.2 version. I do not understand the desire to keep it unlocked but I prefer to keep access for future use if necessary.

I want to update to 4.4.4 stock Samsung or a stable android 4 or 5. Since I have a secondary work s4 some of the novelty Samsung apps are desirable (file transfer and remote viewfinder rest is useless novelty) but flashing isn't permanent and I want to try a well known custom rom such as cyanogen or a google play edition. Known is preferred, had only mediocre experience in the past with roms preloaded with customization. I outgrew the performance roms just want a good daily driver that is up to date. Should I be concerned about usb otg access with the new roms? I like to me able to use my usb flash drives.

Where should I start? It sounds like there is some radio/modem flashing going on, recovery, roms and sometimes it seems like the kernel is separate.

Tldr; Stock 4.2.2 rooted want to update and not make any mistakes to preserve options in the future (not sure if I should even care about knox, locked bb, option to root or all that)
[T-Mobile Samsung Galaxy S 4] Skipjacks:
Its tough to diagnose a completely unresponsive unit like this in general. Doing it without being able to examine it is next to impossible.

In my beat guess though I would say the phone is really damaged and its not a software thing.

You might try taking it apart and simply putting it back together. Maybe there is a loose connection somewhere that this will fix. Maybe.
[T-Mobile Samsung Galaxy S 4] Lurker88 68 65:
Hello, XDA!

A little over a year ago I soft Bricked my phone. I'm very interested in NOT doing that again, so I thought I'd run this by the good people here at XDA and see if I understand a couple things correctly.

I am running on T-Mobile Variant, M919. Currently stock android 4.4.2, rooted using CF-Autoroot.

Last year, I updated from 4.2.2 to 4.4.2, used CF-Autoroot to root and tried to install TWRP recovery. Knox was a new thing and I hadn't heard of it. I didn't realize upgrading to 4.4.2 upgraded to a locked bootloader. I think that's what caused me to soft brick because it caused TWRP to fail.

Oddly, now when I try to reboot into recover, it starts to boot with one line of little blue text, goes to black screen, then boots normally to the system. It's almost like the recovery isn't there. I don't know. I was so excited that I got it working again, I didn't want to touch anything, but this is another reason I would like to upgrade. Having no recovery makes me nervous.

I'd like to upgrade to lollipop, however, I don't want to have to root again. I'd like to stay rooted so I'm interested in trying cyanogenmod. I'd also still like to install TWRP so I have a recovery and can update in the future. Since I've never installed a custom ROM before, I'd like to do this as easily and fool-proof and relatively safely as possible.

I'm still not sure about the locked bootloader. Most threads I've found simply say the M919 doesn't have a locked bootloader. Apparently most don't. I've seen a couple questions about unlocking the Knox bootloader, but haven't found a detailed answer. The only reference I could find to unlocking the bootloader is with the cyanogenmod installer. According to the FAQ, it says "Do I need to unlock my bootloader first?

No, you don't. If your bootloader is locked, we'll unlock it for you."

So.. My plan is to use the cyanogenmod installer to install cyanogen, this should also unlock the bootloader. My understand it that it will also install the cyanogenmod custom recovery.

Once that's done, I can install Flashify and use it to install TWRP. Flashify seems like the easiest, most reliable way to install TWRP.

Then, with the unlocked bootloader and TWRP installed, I should be able to wipe the caches and install updated versions of cyanogen (or any other ROM) as I wish.

I realize this may be going about it the long way, but I'd rather take a few more steps that are one-click automation, than less steps with greater chance of me making a mistake. Soft-bricking my phone has really made me gun-shy and I want to start out slowly.

So, a couple questitons:

Does this plan even makes sense?

Is there any way to verify the bootloader is locked?

Am I just making this whole process harder than it has to be?

Am I nuts?

Thanks you for reading this and thanks in advance for any guidance. I hope that if someone else is searching for answers about the mythical locked Knox bootloader, we can all find answers together.

P.S. In researching this, I saw a mention that wifi calling will not work in cyanogenmod. Is that true? I'd really like to keep wifi calling.
[T-Mobile Samsung Galaxy S 4] a103:
The SGH-M919 bootloader isn't locked. It comes unlocked by default.

Once you install Cyanogenmod via Cyanogenmod installer you can flash twrp using flashify and then you can install any rom of your choice.

WiFi calling will only work on TMobile TouchWiz ROMs, so you'll lose that if you install Cyanogenmod. Currently SGH-M919 isn't updated to lollipop.

I do think that you're making the whole process harder than it has to be.

If I were you I'll

1. Root using cf auto root.

2. Install flashify from play store.

3. Install twrp 2.8.4.0 using flashify.

4. Download and flash Cyanogenmod and Gapps.

5. Reboot and profit [emoji12]

All the best [emoji106]
[T-Mobile Samsung Galaxy S 4] Lurker88 68 65:
Thank you so much for the reply.

I'm not sure I understand. I have read several other places that upgrading to Android 4.4.2 KitKat also installs a locked bootloader. Is that not correct?

In my settings, under about this phone. It simply says "Secure Bootloader Status. Type: Samsung."

I already am rooted using CF-Autoroot. So, yes, if the bootloader really is unlocked, I would love to flash TWRP right now. Is there any way for me to verify the bootloader status? I will attached my system info. Can I flash TWRP on this?

[T-Mobile Samsung Galaxy S 4] a103:
As I mentioned before the bootloader for SGH-M919 is unlocked which means Samsung ships those with bootloader unlocked out of the box.

If you're rooted then follow steps 2 through 4.

They must be referring to knox which is a security by Samsung. Read about knox here

I had no experience rooting and flashing ROMs whatsoever before but I followed instructions online and now have rooted two devices and loaded custom ROMs on both one being T-Mobile S4 and other Nexus 7 2012( WiFi) both running Cyanogen 12.1 Nightly which is running Android 5.1.1 it took me 2-3 hours first time to get everything done second time 30 mins. I used CF-Auto Root to gain root access and have supersu as my root governor and use TWRP as my recovery. I don't have experience with Clockwork Recovery but with TWRP the task to install a custom ROM is simple: launch recovery (assuming you know how to install custom recovery) wipe device/factory reset then press install and click on the zips I.e : Google apps and custom ROM zip files then you should see something to the effect of done or continue then swipe to flash then wait until the ROM boots finally you have installed the new custom ROM

Hey guys I need to be pointed in the right direction... I have two Tmo GS4s one is rooted running a custom rom. The other one is completly stock on android 4.4.4 and it has Knox but it has not been tripped. I just finished sim unlocking it and now i want to root it and install a new rom to see if the sim unlock will still stick after root and a new rom. My other GS4 has the Knox flag tripped but on my other GS4 i would like to root and install twrp recovery but from what i assume and dont know if it is correct but once i try to flash a recovery that is what trips the Knox flag right??? I guess what i want to do is root the stock gs4 on 4.4.4 with twrp recovery and new rom without tripping knox if that is even possible? I have searched for way to root 4.4.4 without tripping knox but either im not searching good enough or its not possible. So is there anyway to root+twrp+custom rom without Knox tripping? I really do not care about setting of the Knox counter but if it can be done i would like to do it lol

[T-Mobile Samsung Galaxy S 4] _Spectrum:
Hello. I just bought a T mobile variant of the S4 and I have a few questions about flashing Roms. I originally came from the AT&T S4 Active, which has a locked boot loader, so I'm not very familiar with some of the ways flashing works.

First question. Is it possible to flash cyanogen mod 12.1 from, let's say from stock jellybean or KitKat? Because in the S4 active, if we were to flash a KitKat 4.4.2 ROM for example, we had to get on clean rooted stock 4.4.2 and flash the custom ROM. So basically the firmwares had to match up with each other in order to flash. Since CM 12.1 is on lollipop, does that mean that my s4 on T-Mobile have to be on lollipop was well, or can I be on jellybean,kitkat?

Second question. Does installing any custom ROM or cyanogen mod trip samsung Knox?I'm just curious about this question and thinking it probably does, but I'm willing to take the risk anyway because I wouldn't mind losing warranty. If there is a way to reset the counter back I guess it would be a nice addition.

Third question. I will be using a at&t Sim card on my new T-Mobile s4. So all I have to do I pop in the Sim card and reconfigure the APN settings in order to get 4g LTE on the at&t network?

And finally. Which custom recovery would you recommend?(between cwm, twrp, and philz)
