By no signal, do you mean it is literally out of service? Or just showing fewer bars than you expect? Note that a lot of ROMs out there show much lower bars for a given level of received db signal as compared to the stock Touchwiz and even iOS. My phone went from stock, showing full bars pretty much everywhere to much more dynamic 1-3 bars being the norm except in the best places. However, the actual signal as measured in db was the same and the phone worked fine. Basically, phone manufactures in cahoots with the carriers bias the bar representation to show better signal than they really should. AOSP and similar roms show a more realistic depiction of the situation.

Post some db values (settings, about phone, status, usually gets you there) from various places, and if you have another phone handy, post its values for comparison.

S4 banda issue

Hi there ,

I have an s4 sgh m919 from tmobile and I live in venezuela I already unlocked the phone but it only receive EDGE signal because my carrier lte 4g uses the lte band3 (1800mhz) wich this phone doesnt have.

Is there anyway to "unlock" that band ? Or I have to buy the international version?

Hello!

I have a couple questions about the SGH-M919. Mine is on latest update (4.4.4)

1) Is there anyway to root it currently? It is fully stock and knox hasn't been tripped.

2) Today I decided to play a game that I hadn't played yet. It was Zens Pinball HD. My phone after words got really really hot, laggy, and drained the battery. So, finally I unplugged the battery and it only seems to do it when I play that game. Is this normal for this phone, or is it a bug in the game?
[T-Mobile Samsung Galaxy S 4] a103:
You can root on 4.4.4, use towel root or cf auto root.

I used this file and seemingly nothing was done. It isntalled via oden but when I started up the phone nothing changed. ALl my old data was still there too.

SO my new issue is this:

I can send and receive texts

I can surf the web,

BUT I can't here phone calls....

THE WEIRD PART IS THIS when I use wifi calling I can here phone calls just fine.

I have tried headphone port (same issue) thinking its baseband. I have factory reset (like 6 times) I have used a diffrent sim card. The sim cards work just fine they even send cals out and answer them but you can't here anything. I have not tired blue tooth. I think I may have the wrong F.w???

SOmeone has to have an OFFICAL tmobile 4.4.4 somewhere. Over at sammy they have two different F.W Im SOOOO frustrated with this POS phone. IT is certainty not the operator. I am more than competent with technology. I had this same issue with a note 2 last year. It seems like every year I get sick of iOS and get an android only to have mad issues.

factory reset (start phone off and hold home pwer and volume up at same time, relese power keep other two held down)

Then select wipe/factor reset

then enter download mode (like before but use volume down button) when it comes up with its warning just push the volume up plug into comp if not already.

USe oden to install 4.2.2 (or any newer F.W.)

maybe need triangle away? BUt that just resets flash counter. NO bid deal unless warranty needed.

What controls the volume clarity in a ROM

I have tried many of the newer ROMS like Goldfinger, GoldenEYE and Sickness. The problem seems to come in as newer versions are released for each ROM. For example, when I upgrade to any version of GoldenEye past version 24 I get horrible sound quality form incoming calls. It sounds distorted (high pitched and underwater). I have tried several ROMs and seeing that they are based of similar Firmwares I am thinking that there is something in the newer versions that are not in older ROM versions that control sound. Is this the case and if so what controls the sound quality?
[T-Mobile Samsung Galaxy S 4] a103:
Are you on latest boot loader/modem?
[T-Mobile Samsung Galaxy S 4] josephh71:
Yes/No

I have updated the modem but I kept the old bootloader. I was reading all of the documentation of not being able to downgrade after the update of the bootloader and locked versus not locked and I got confused. Is it better to upgrade both through the factory firmware updates? I usually just choose Roms that allow you keep the old bootloader and upgrade the modem.

Can somebody tell me what exactly a bootloader is... How do I find out what I have?

Are there issues flashing 4.4.4 roms for someone like me who's been flashing roms without issues since I bought it? I don't think I can upgrade legitimately through the phone/Android itself cuz it knows I'm flashing roms right?

I've got access to a computer now, which before I hadn't. So I hadn't been flashing any modems, Just the roms. Can you flash a bootloader? Sorry if I'm dumb

-----

after reading some more of this thread, I'm like the guy a few posts back. I've never messed with my bootloader, but it came loaded with 4.4.2. I just rooted, and started flashing roms. I haven't flashed any different modems cuz I haven't had a computer. Am I only going to have to mess with the bootloader / modem if I'm having issues after the flash? Thanks

Haters Stay Anonymous
[T-Mobile Samsung Galaxy S 4] OriginalGabriel:
Easiest answer is that a boot loader is like the bios on a computer; you don't have to mess with it, unless you know what you're doing.

As for ROMs; flash what you want, as long as it was developed for your device
[T-Mobile Samsung Galaxy S 4] rlichtefeld:
You bootloader is what first runs when your phone boots up. And, what it is similar to in a WinPC is the BIOS. Also, in the newer bootloaders starting at MK2, there is the Knox flag, which is why some people want to stay with the MDL version.

You can check your version by downloading the free Samsung Phone Info app from the Play Store.

The one reason you may want to upgrade the bootloader is that the newer modems require both the modem (also called the baseband) and the bootloader to be the same version. Some people say the NH7 modem works much better. So, if you have been flashing ROMS, and don't care about the Knox flag being tripped, make a backup in Recovery, and flash the NH7 version firmware either through ODIN or KIES, and then restore your backup. That will give you the most current modem and bootloader. The only downside to some people is the KNOX flag. However, if your bootloader is MK2 or newer, you already have KNOX.

There are several threads here on flashing the modems, where to find the firmware, etc.

[T-Mobile Samsung Galaxy S 4] lordcheeto03:
Just a little nit-pick/correction: You can update the GSM modem/baseband without updating the bootloader. This also stops the data drops and other problems related to using older modems with newer ROMs. The LTE modem is the one that is tied to the bootloader and isn't necessarily required to be updated unless you're having problems with LTE reception. I, like many others here, am using the NH7 modem on MDL bootloader and have no problems.

SIM unlocking - 4.4.4 M919UVUFNH7

I bought a phone on ebay to take overseas (clean IMEI) and when I put in a local SIM I see the phone is SIM locked. Google has been a partial help but most of the info seems to apply to earlier builds of the the phone.

Note: I am interested in keeping this phone with the Stock ROM and Modem at this point. I am somewhat comfortable using odin and other tools. I used cf-auto-root to root the phone and have installed custom ROMS on my previous phone., although I prefer to use automated tools.

1) How do I know if my phone is region locked ? (the seller said he had used it for a few moths but I can't verify this)

2) Can someone point me to directions how to region + SIM unlock this phone ?

3) I found several links to a tool which will do this http://gsmbdking.blogspot.co.uk/2014/10/samsung-sgh-m919-444-m919uvufnh7-unlock.html but I am a little weary of installing things from sources that are un-verified. can verify the source files linked from this page ?

thanks !

UPDATE:

T-Mobile was very helpful and assuming there are no issues with the bill they will send a code.

Using the Samsung Tool v.18.1 from Z3X it is possible to unlock the phone on your own. (I did not have time to test this although others claim to. see above URL from gsmbdking )

a) root the phone first using cf-autoroot

b) download the firmware update from here http://z3x-team.com/support_files/

I want to put a custom rom on my phone but, even after following YouTube videos, or following the OPs install steps or those that worked for other members, I've never been able to successfully flash any custom rom.

Why? When finished

Each time following an attempt, I have to do a firmware recovery using Kies 3. Then I downgrade to NC5 kernel, use TowelRoot to successfully root followed by SELinux to set permissions to Permissive. SafeStrap 3.75 is then installed via apk.

The problem I experience is when using SafeStrap, to install Hyperdirve RL 19 for example, at the completion of the process there are errors concerning /system. SafeStrap at that point indicates I have NO operating system? If I reboot, I lose SafeStrap .

What am I missing? What would prevent SafeStrap from accessing and writing files to /system on a phone confirmed to be rooted?

Look on eBay. There's a bunch of companies that will sell you the code. I've seen code cost 2-3 bucks to 20-25. You'll have to give them your imei and such, and within 12-24 hours you'll have your code emailed.
[T-Mobile Samsung Galaxy S 4] rlichtefeld:
You do realize that this forum is for the T-Mobile version of the S4? The TMO S4 doesn't have a locked bootloader, and doesn't require SafeStrap.

The NC5 kernel is for a Verizon. Both the VS4 and VNote3 use that designatiuon. I think you'll get much better answers on the Verizon forums here:

T-Mobile pushed the new 4.4.4 update to me yesterday.

Now I see that Location Services has changed. I read about it online, and I think the concept is sound.

BUT

Now I just turn "Location" on and off. For Navigation I need to have "High Accuracy," but for anything else that's pretty much not important. For example, I need to leave "location on" for my weather to update, otherwise it says "I DON'T KNOW WHERE YOU ARE. PLEASE TURN ON LOCATION SERVICES." But it appears I have to go into the Settings at this point to flip between "battery saver" and "high accuracy."

Which is a bigger pain than just turning GPS on and off when navigating. Am I missing something here?? It'd be nice if there were a widget for that...
