[T-Mobile Samsung Galaxy S 4] DigitalJedi:
Good to know. Thanks. I just remembered back in the Vibrant and T989 days that a modem/radio update could sometimes give you a better signal. I think in the Vibrant days you even had to have a certain radio and bootloader running depending on the Android version your ROM was based off of or you could end up with no signal or rainbows during the boot process. I didn't know if those days were long gone or if I needed to concern myself with it.

Also, I took a shot and made a build.prop tweak that made my phone show up as a T-Mobile GT-I9505G in the market. At least the Tmo part is there. Still not showing a M919, but I don't guess it is a big deal since everything is still working.
[T-Mobile Samsung Galaxy S 4] Skipjacks:
The HTC Sensation was like that too. You needed certain radios to flash different Android versions. And different radios made huge differences in signal strength depending on where you were. (And I mean where you were in the United States. Not like that people in Brazil needed different radio than people in Montana. I mean people in Montana needed a different radio for the best signal than people in Ohio.)

For the S4 I don't see that being an issue. There are only 3 basebands available for the T Mobile version. I've tried 2 of them and not seen a single decible of difference and haven't seen a sinlgle post on this forum or the 9505 forum about different radio software giving wildly different signal strength. If that was a thing I have to believe you'd see hundreds of posts about it.

So I think the S4 just isn't plagued with that issue.
[T-Mobile Samsung Galaxy S 4] Cal-El:
I do not have any issues but just wanted to post a thank you for Skipjacks. Dude you rock!!!! Everyday you are here spending your time and lending aid to any and all and for that sir I salute you. Thank you. :good::good::good::good::good::good:

No problem at all. I'm glad to help.

2 years ago I knew nothing about Linux or smartphones or anything else related to the topic other than that I knew iPhones annoyed me.

XDA helped me learn everything I know now and continues to help me learn more every day. The only thing I ask in return from people I help is to pay it forward. As you learn and become better at this stuff, give back what you've learned and help new people out.
[T-Mobile Samsung Galaxy S 4] Cal-El:
Right on. In 2009 I started a group called the "Rescue Squad" we would get on everyday and help as much as possible but it kinda of petered out awhile ago. Going give it another go I think.

This is neat. Tell me more. How does this work?
[T-Mobile Samsung Galaxy S 4] Cal-El:
Well it was back in the day when the top phones were wm 5.0 lol but we were just a bunch of people who found out how much you can learn just by trying to help people troubleshoot their devices. So we would make it a point to try and solve (not just post a few suggestions) but actually solve peoples problems and walk them through various things Rom flashing and so forth. Its amazing what you can learn just doing Google searches for people who just don't want to search or just don't know what to look for. Thats about it though. It was started when the structure of the forum was completely different than it is now. Back then there were alot less moderators and we needed to band together a little more to solve problems on our own. It was mostly devs back then and if you didnt cook Roms ( I did one or two Roms for the tilt and touch pro 2 lol) you just tried to help out in anyway you could, it was more of a community back then.

recently i have actuallized mi cell phone android 4.3 my version is m919 too, i dont know how to speak english is any easy way to make it root i have tried with odin but is doesnt work,

could you please help me?
[T-Mobile Samsung Galaxy S 4] Skipjacks:
CF Auto Root should still work I thought even with 4.3. It trips the Knox counter, but I think it still roots the device.

See here...

http://xdaforums.com/showthread.php?t=2294005

If that doens't work try this...

http://www.theandroidsoul.com/universal-root-de-la-vega-script/

This method is supposed to root the S4 without disrupting Knox. I have no first hand experience with it though so I can't tell you if it really works.

And again I'm showing you a method that I have NOT tested. So if I were you I'd research this more before I actually did it. This is just a place to help get you started.

Also, you said you don't speak English very well. Are you sure you're using the right files to root? This is the T Mobile USA forum for a version of the S4 that is ALMOST exclusively sold in the United States. If you are using a rooting method made for the T Mobile USA version on the International version of the S4 it not only won't work but could break teh device. So be careful!

Good luck! And don't hessiate to come back here with additional questions. (Unless you do have the international version and then I'll show you where the bes tplace ot ask about that version is)

I can confrim this works for T Mobile SGH-M919 for the LTE models only. I sussefuly installed root an rom of choice and did not trip anything Knox related. Just make sure to read everything...twice
[T-Mobile Samsung Galaxy S 4] MrBaron8:
i have tried the first one you mention and other one they were both 4.4 and it would install good, except they would get no service. is that a problem with what? kernel? what if i just install a stock rom from google play? i had gpe 4.3 running great but after i received the ota update and couldnt install i thought it was because of the custom recovery.
[T-Mobile Samsung Galaxy S 4] Skipjacks:
I'm sorry, I don't know. I haven't played with 4.4 yet at all. I've heard people are randomly having connection issues.

The short version might be as simple as these are new ROMs that are still in beta stage and are going to have bugs. They might also need the updated baseband that came with the 4.3 OTA update. You can install that baseband without the bootloader that adds Knox. I don't know if that will solve the issue youa re having though.

Kind of a stupid question/ does flash stock rom by Odin void the warranty? and add to the counter?
[T-Mobile Samsung Galaxy S 4] Misterjunky:
re: stock rom

Flashing stock Odin flash official M919 4.2.2 firmware does not void the warranty

or add to the counter.

It is just like when we get OTA updates which does not void the warranty either.

[T-Mobile Samsung Galaxy S 4] Skipjacks:
This is a very rookie friendly thread and we are happy to help with even the most basic questions, but we still do ask that you give some effort to searching before asking questions. Otherwise we end up just repeating the same answers over and over and over.

You say you searched, but you didn't really. There are 2 possibilities for rooting. Both are outlines in post 1412 of this thread with links. That's all of 1 page back, from less than 24 hours ago.

Good luck I hope those methods work for you!
[T-Mobile Samsung Galaxy S 4] Skipjacks:
What error? What process did you repeat?

You have to give us something to work with. I have no idea what you did or what exactly went wrong. Give us ALL the details. Dont' assume any detail is too small or unimportant. I'm sure we can figure it out.
[T-Mobile Samsung Galaxy S 4] Skipjacks:
Check in the Settings menu, then About Phone to see your ROM version.

And we do not get into discussions about what the best ROM is here because there is no correct answer. You have to try them all and decide which one is the best one for you. Just like there is no 'best car'. We all have different needs and opinions. It's all subjective and such discussions ALWAYS degrade into silly battles about ROM loyalty with people bashing other ROMs and XDA just isn't going to have it.

The ONLY way to see what ROM is best FOR YOU is to try a bunch and decide.
[T-Mobile Samsung Galaxy S 4] Skipjacks:
I don't think so.

But I'm not 100% positive. You are trying to use a CDMA device on a GSM network. Even if you get LTE to work, something else isn't going to play nicely. This just isn't interchangable hardware.

Hey guys, I used the CM Installer on my SGH-M919 (jfltetmo). However, the installer changed my device name to jfltexx (international version). Now when I try to flash packages meant for jfltetmo, it gives me an error. I know the two are very similar and that I can edit the package's install script but I'd rather have my phone reflect the correct device name. Is there any way to change it back?﻿ TIA
[T-Mobile Samsung Galaxy S 4] Skipjacks:
Good one....

Do you only get that error if you are trying to update the existing Cyanogen install with a newer release?

Or do you get it if you try to do a full wipe of the system and data partitions and try to install a completely different ROM?
[T-Mobile Samsung Galaxy S 4] besweeet:
Quick question:

I'm thinking about switching from an iPhone 5 to the T-Mobile M919 S4. But, I have a few concerns:

1) How's T-Mobile's compatibility/performance on the S4? With my iPhone 5, I'd say it's pretty bad, to where it doesn't hold onto LTE in places my temporary Nexus 5 did. It'll often drop to EDGE for a while when leaving an LTE area, taking its sweet time to actually switch to HSPA+.

2) Battery life is pure crap for me (typically losing 1% every 2-4 minutes with extremely basic usage. What's it like, in general, with the S4? From what I've read, it's certainly not bad at all. And with all the custom ROMs and kernels, I think I'd enjoy tweaking things around.

Thanks.
[T-Mobile Samsung Galaxy S 4] Skipjacks:
1) This is going to depend on where you live. It's kind of a crap shoot. If you know someone with a T MObile S4 your best bet is to put your SIM in it for 5 minutes and see what kind of results you get.

2) That batery life is awful. You can deffinately make it better with the S4.

3) You are asking if the S4 is better than the iPhone an a site devoted to Android modding. Consider the source of your answers here. The general opinion here is that the iPhone is dumb and represents all that is wrong with Smartphone software and design. So keep that in mind when judging the answers you get. But that said...yeah ditch the iPhone and get the S4. It's a bazillion times better in every aspect. But that's just my opinion.
[T-Mobile Samsung Galaxy S 4] besweeet:
Yeah, it's somewhat odd. The battery drains at the same rate, regardless if Wi-Fi is on or not, or if my SIM isn't even installed.

My only concern is that the phone is too big physical to where one-handed operation might not be ideal. Although, my recent 2-week trial of the Nexus 5 told me that it wasn't that bad, so I'm not sure.

Thanks for the response, though.
[T-Mobile Samsung Galaxy S 4] markn951:
Yes, I get it even after wiping /system and /data, this is why I don't think it's as simple as editing the build.prop. I think the CM installer actually did something to the phone. Weirdly, if I boot into Download mode, I still get "Product name: SGH-M919" which is correct...
[T-Mobile Samsung Galaxy S 4] TeethMummy:
I installed the latest 4.4 VirginRom and everything seemed to be working well, but then I would lose service randomly. It seems whatever network the phone is set to (LTE/3G/2G) is the only one it will access, and instead of moving to a lower network when there is no LTE, it instead just gives the empty bars and NO SERVICE message. I tried everything I could think of to enable this feature, so when i'm commuting I don't lose service completely, but as unable to find any method to do so. Any tips? back on Touchwiz now and not happy about it
[T-Mobile Samsung Galaxy S 4] a103:
You need to change your baseband to MK2. Check the Q&A in that ROM section. It has the instructions there on how to do it. I changed it myself and haven't had any network issues since.
[T-Mobile Samsung Galaxy S 4] markn951:
I seem to have fixed it. I wiped the phone and then followed jovy's instructions here (third post) to flash stock from Odin. This left me with stock ROM with TWRP. I then wiped /system and installed OMNI for jfltetmo, and it worked great. I think the problem is solved. I still have no idea how CM installer did it or how what I did fixed it, but it did fix it.
[T-Mobile Samsung Galaxy S 4] TeethMummy:
Appreciate the help.

I chickened out and flashed back to the clean 4.3 rom. That modem switch seems like more of a hassle than its worth. I'll wait for a clean 4.4.1 GPE rom to hit. Thanks, though!

You are welcome. Hopefully it gets fixed in the 4.4.1 update. BTW it's a one time procedure, so once you are done; you are good to go :D

followup

For educational purposes only: When using 4.3 GPe versions this was not a problem. What changed between 4.3 and 4.4 that would cause this? (referring to why the phone powers up on it own when plugging in power)
[T-Mobile Samsung Galaxy S 4] HeWhoGameZ:
So if I were to switch from one ROM to another. Apps and google think that the new ROM means new phone/device. How to I go about changing the number thingy to make it think I have the same phone as it is now. I remember that you have to change it or something for Titanium Backup to restore your apps properly. Or does Titanium Backup do it on it's own?
[T-Mobile Samsung Galaxy S 4] Skipjacks:
Titanium Pro can do that.

However, this isn't a big deal. Sometimes it can prevent some paid apps from reinstalling, but you'll always be able to get them from the Play Store again (you will not have to pay again) and then Titanium can always restore the data to them.

All in all, it's not worth worrying about.

Hi,

I apologize if these questions have been answered before, but I'm getting tired and don't have the energy to dig through the entire thread. Besides, you said you were n00b friendly :p.

Is there a way to temp root the phone?

The guides I've found so far seem to involve flashing (http://xdaforums.com/showthread.php?t=2268880), which I assume would be permanent.

I just got the phone and am likely going to keep it, but am hesitant to permanently root at this point in case I want to return it, which leads to

If I do root the phone, can I undo the root without any trace?

All this stuff about counters is making me worried I can't revert to stock and return if need be. And finally, the question that led me down this path in the first place:

Is really no way to enable a bypass a secure lock screen (i.e. pattern/PIN) to go to the camera in the Samsung lock screen, other than to put on a different ROM?

I'd like to try out the Samsung ROM first, but looking at the crapware that's on there, maybe there's no point....

Lastly,

If the answer to #2 is no, is there any way to restore from a Titanium backup without root?

(I'm restoring data from an old Android to the new phone)

Thanks!
[T-Mobile Samsung Galaxy S 4] HeWhoGameZ:
Well here is what you need. I don't remember if there is a temp root but I think it'd be called shell root or something. If you were to return the phone and you were rooted and/or had a custom ROM. Then you would need to DL triangle away from the gplay store. That'll reset the counter so it looks like you never did anything to it. Then you manually delete your data off of the device (pictures, notes, downloads, etc.). Then use Odin to flash back to stock and you are good to go.

Also about #3. You can download xposed framework (root) and scroll through there. There's a mod in there that'll do what you are asking.

Searched to no Avail - Cannot find my answer.... HELP!

Ok noob here, but I am no noob to rooting or roms. I just did wicked's rom with the 4.3 kernel no Knox on a friends phone. Did it fine 1st try. I have been rooting and rom-ing since my Motorola Cliq/Dext years ago!!!

However one thing I am uncertain about that you all may know more than me is how these interchange within phone lines. Example - and my question - that I cannot find anywhere lol... I want to buy the Galaxy S4 ACTIVE... Aka same phone, same carrier (well active models were originally made for at&t and I am with t-mobile - but I can get international version - or just wipe at&t off the US version) and if I do a custom boot-loader, like CWM... Would I be able to use rom's and kernels like Wicked and the kernels linked in thereto go from 2.2 to 2.3 with the modem, then flash wicked v9 on there from CWM when version 9 comes out?

I mean the Active is the same hardware inside, just the case and buttons and speakers are coated and textured as to make dust and water proof to so many feet. Basically can I use a Galaxy S4 Rom and Kernel on a Galaxy S4 Active phone? Their specs and internal hardware are identical. So should it matter technically they are 2 different model numbers? I am on T-Mobile right now with a Galaxy S Relay (I love my keyboard but am ready to switch - I have over 300 apps and need more space and internal memory and a faster QUAD core not duo-core processor and more ram)

So anyone can help would be appreciated. Also anyone with a case on their phone, although the S4 Active has raised buttons not flat ones built into the screen, the difference is very minimal could I use a regular case for S4 for the S4 active? I noticed many of the more rugged cases don't have an active model just s4 model. I really want a rugged case with screen protector built in. My case on current phone cost $80 but I love it. Can throw the phone down on the ground won't even cause one issue lol - (never did that but just saying its an amazing case)

Thanks all :)

---------- Post added at 09:44 AM ---------- Previous post was at 09:26 AM ----------

Another quick q -thanks all... Just did wicked V8 on a friends phone - noticed unlike the Cyanogen Mod's it does not have an option to add screenshot, so when I hit power button and it comes to power menu, I can click screenshot and snap a pic of the screen.

There's 10's of apps out there just curious since until now with wicked rom (which I love way better because I have some t-mobile apps like Name ID and such on it and can make use of them) - so anyways, which app do you all prefer best for enabling screenshots since Wicked's rom is rooted and ready to go. Preferably one that you don't need to open the app - I can just add it to my power menu or even the menu in the top status bar :)

Again, not new to this thing but a little stuck what program you all have tried and tested and works great. I don't want to go through 30 programs to find one good one lol
[T-Mobile Samsung Galaxy S 4] Skipjacks:
Careful. The S4 Active and S4 are NOT the same phone. They are VERY similar, but are not the same. The ROMs are probably not interchangable. For one major glaring difference, teh screen is differerent. One has an LED screen one has an LCD screen. The libs to run each peice of hardware are different.

There are also some slightly different frequency bands they run on.

The S4 is also a different size than the active so cases are absolutely not interchangable.

And screenshots can be made by holding power and volume down. Should work on every rom.
