I'm curious about something regarding the newer ROMs in the dev forum. Why do so many of the newer ROMs coming out insist that you have to be on the JB OTA before flashing? I'm familiar with flashing on other phones where you just wipe and flash, and move on with life. Does this have to do with the radio/modem? And if that's the case, could you not just flash the ROM and then a modem? I'm just trying to get some clarification stemming from genuine confusion.
Not really sure but could it maybe have something to do with the trust/compatibility deal thing?? Idk I was wondering the same question in op. By no means is this the answer I was just throwing this out there. Hopefully someone can shed some light.

No, that link did clear it up. Not sure how I missed it before, but whatever. Seems to be a security feature for the newer ROMs, if I read that post correctly.
Its not just a security feature, but that's the gist of it. Adam Outler explains it http://www.xda-developers.com/android/trustzone-a-dimension-of-multiple-worlds/ .

No, its the tz partition that is only changed throught the OTA/LGNSPTing that is needed. I'm not quite sure of all the specifics, but this tz partition is what you need to flash these new roms.
Excellent explanation, much thanks. Quick follow up question now... Once the OTA update is done, is that more or less permanent for the purposes of ROM flashing? In other words, does the phone have to be put back to stock every time I want to change ROMs?
Sent from my LG-E970 using xda app-developers app
You only need to do it would once. Once the tz is put in place it stays, unless you lgnpst to the n4 conversion or to ICS. Flashing a ROM in recovery won't change it.
Beautiful. That's what I figured, but better to ask before bricking my phone. Thanks again.

So I flashed one of these roms,Vanilla rootbox to be exact. Can I now flash any of these newer roms or do i need to go back to the stock 4.1.2 before flashing another one of these roms?

Standard "I'm not a developer but..." disclaimer here. You can either revert to the stock ICS build and get the OTA update, then re-root/unlock, or I seem to remember a flashable stock 4.1.2 zip file in the development section that is supposed to take care of the TZ stuff to let you move on with life.
Feel free to correct me if that's not good information, though.

I already lngpost-ed to the 4.1.2 and then rooted and then flashed one of these newer roms. My question is really can I go from one of these roms to another without going back to the stock 4.1.2 and rooting again?
That is my understanding. Once you have the TrustZone partition set up from the stock JB, it's there and you don't have to mess with it again. Unless you do something that kills it, like go back to an ICS rom.

Sweet. Thanks for the help. I'll post back if for some reason it does not work
Good question OP, I was wondering the same thing and this LGNPST thing is confusing.
So, I am currently running SnowJB (which I believe is 4.1.2?)
Do I need to do the LGPNST in order to install these newer ROMs, such as Vanilla Rootbox? Or am I all set to go ahead and flash new ROM?
To anyone confused, ask yourself...
Did you receive the 4.1.2 (JB) update over the air OR did you use lgnpst to flash to 4.1.2?
If yes, then you can begin flashing as usual without having to lgnpst every time you change ROMs.
If you haven't used one of these methods then you need to do one first before flashing the new ROMs.
Simple as that.

I want to post this thread to help those of you
who are new to android and to the Galaxy S4.
There are many videos on how to do kool things
to your S4, but most of them don't include the
Verizon version of those kool new things. If you
need help and you are relatively new, I ca listen
to your questions and help you out. Most of the
developers are too busy doing other things so we
can have kooler things for our devices, they don't
need another task to take upon their shoulders.
Thank you all developers for Giving us the great
power that comes with Android.
Don't take this the wrong way, but something about this post makes me hope that you'll only be pointing people in the direction of the proper guide, not trying to explain it.

No. That's not how android works. It's not like an iPhone where all of the updates come from apple. Android updates don't come from Google unless you own a Nexus device or a GE device. They usually come from the OEM and carrier. And it's not universal. You can't apply an update from another carrier on your device. The only thing you could do at this point is to install a custom recovery like TWRP or CWM. I think there are a few ROMs in development that have a 4.3 base, but that's it. Also, you can't maintain the MDK version and also update to 4.3. They're two completely different versions with many of the components being different, including the bootloader and recovery.

There are no touch wiz android 4.3 yet.... your best bet is staying on mdk.... because any update that verizon pushes out will lock the loki hack and brake root.... check out the post on the list of ROMs the GS4 has.

Thanks for your willingness to help out folks newer to Android.
thanks for the info. my gs4 is rooted on mdk with goomanager's recovery. i have been happy with touchwiz so far, so i haven't flashed any other roms yet. i disabled the OTA update with titanium backup but i am a little curious about the VRUAME7 update. what exactly is the deal with that, you can root but not use a custom recovery (so your stuck on touchwiz) or can i get a rooted version of it and have recovery too while enjoying whatever the new updates are.
I have one question for everyone. Depending on the answers I get, the if it aint broke dont fix it rule will apply. So here it goes. (fingers crossed)
I was on Beans MDK Rom with stock kernel and decided to try Darkslide Rom. My phone didnt like the that rom so I flashed back to Beans using my nandroid backup using TWRP. Everything is working fine with no issues at all. Here is where my question comes. I looked at my baseband and it show ME7. Why? My backup should have put me on MDK...right? How I get baseband back to MDK? Anyone have suggestions?

If you have a device that wasn't officially updated to ME7 then you can flash any of the ME7 roms in the dev section. You'll enjoy the new features such as apps2sd and you can flash the ME7 modem separately (Darkslide flashes it for you).

The baseband refers to the modem which isn't changed by flashing most roms or restoring nandroids. However, since Darkslide flashes it alongside the rom (only rom that does this) that is why your baseband changed to ME7. You can get back the MDK modem in a few threads but there is an easy one to find in the second post of the BoneStock rom.

How do I tell which build the phone is at the store
Hi,
I'm new to android and all internet phones.
I'm using a relic right now Motorola e815 with just the phone (text blocked) and I need to get a GS4 for Verizon. I modified my e815 7 years ago, so I could put ringtones on it from the card, but the state of the art (SOTA) curve seems a bit steep with never having used an android phone.
I would like to get the GS4 root it and put custom ROMs on it. From what I read currently, I think this can be done only on the expensive developer phones, or pre ME7 builds.
My questions are:
How do I tell which build the phone has at the store so I can tell if they are selling ME7 or not? Another thread from today said the stock 16gb phones at the store a few days ago when he got his were all pre ME7. Another thread on another board said try asking for the least popular color. OK, but how do I quickly check what the build version is. Yes I've UTFSE, but I must not be calling something by the correct name in the search engine.
Also how do I make sure the CSA does not update the phone and that there is no automatic update before I get home and turn it off? I don't want to find a phone I can root and ROM, but have some idiot screw it up for me by doing the OTA or it happening on my way home from the store. Also if I go to get an app from ? (titanium backup) to turn off autoupdate, do I risk it automatically updating before I can get the chance to root it?
Thank you very much for any help your suggestion you have to offer me and anyone else reading this.

I can answer SOME of your question... I believe that there is really no way to know if the phone has the me7 update on it without turning it on to check... I'm sorry.... I got my phone around the same time the new update was coming out. You can always ask the store assistant to try to set up the phone while you're in the store, that way you can quickly set it up... then go to settings/more/about phone/build number to check if the last three characters are me7 or not...... Although it would be hard to find a way out of that if you find out it has the me7 update.......
If you know for sure that the phone does not have me7 on it for sure..... turn all data off ... wi-fi, moble network... etc.... and download Titanium Backup apk to your computer..... from there you can transfer it to an sd card or USB it to your phone and install it manually....... BUT... for the app to work you have to be already rooted.... so before you buy the phone you need to watch this video http://www.youtube.com/watch?v=Gm3jw3hft1g and follow all instructions for the downloads... You dont nee a network connection to root.... DO NOT TURN YOUR DATA/WI-FI CONNECTION UNTIL YOU FOLLOW ALL I'M TELLING YOU..... once you are rooted SUCCESSFULLY..... run titanium backup find "SDM 1.0" click on it and freeze it!... this will make it so Titanium Backup will Deny the process that pushes the updates.... ater THE APP HAS BEEN FROZEN. You can turn the data back on.... Having done this... you are now able to install the Loki hack and flash ROMs... instructions for Loki hack= http://www.youtube.com/watch?v=Nc_Mh_nNPPw ...... if you have any more questions... PLEASE ASK.... Good Luck. so review...................... ALSO if you need very extremely thorough instructions on how to use Titanium backup see this video. "" http://www.youtube.com/watch?v=oZEa10WtFng
1. Find GS4 without me7
2. Turn off all data
3. Root GS4
4. Download Titanium Backup.apk to PC
5.Transfer apk to phone storage
6. Install Titanium Backup manually on GS4
7. Find "SDM 1.0" and Freeze it
8. You are now safe from me7 update
9. Turn data back on if wished
10. Loki hack bootloader
11. GO CRAZY!!!

Well I think your referring to flashing custom ROMs that are " upgraded" past MDK. You can obviously do that without issue. You can also flash any modem you want ( baseband ).
But what people are referring to when they say do NOT update an MDK phone is either an OTA Update directly from Verizon... Or using Odin to flash stock firmware beyond MDK.
If you do that your bootloaders going to lose the Loki Exploit and bye bye custom recovery... Follow me??

Your bootloaders going to be MDK
And your radio will be whatever one you last flashed. And depending on what ROM you're running, in your about phone it MAY show you a different build other than MDK. That's just the build the Dev based the ROM off of.
Sent from my SCH-I545 using Xparent Blue Tapatalk 2
Like the poster above said, flashing Modems/Radios will change what's shown as your "baseband" in about phone, but won't affect your MDK bootloader. So your bootloader version was never upgraded/downgraded.
phew!
Ah...so it's not all about me. Thanks for the thoroughly explained answers from both of u guys. That really clears things up. And glad to know about the modem being OK to flash/upgrade. Well, I am EXTREMELY lucky- seeing how I tried an OTA update last week after having to flash a retail image to my S4 with Odin (soft brick)...because the OTA update failed! I will NEVER try that again!! Ha. Thanks for the info!

Definitely don't update via OTA or use anything in Odin other than MDK.!!!
After you root your phone use Titanium Backup and freeze "SDM " and "FWUpgrade" then make a backup in whatever recovery you're using.
Those two things being frozen ( I think SDM is good enough ) will stop any OTA possibility. Although being rooted and whatever else you may have done should be enough to stop it. No need to risk it lol

Hmm...I searched Titanium for SDM and anything with FW (FWUpgrade) in it, i dont see anything there. I tried just browsing too. Maybe BoneStock v2.1 (VZW, TW, 4.3) is built without those files already? I'd like to do what you're recommending though, that makes so much sense. I found "ConfigUpdater" but, that's probably not what I want, right?

You're right, cross-flashing might leave remnants (features) of the previous ROM, but there's no guarantee that they'll be utilized correctly or linked correctly to the system files. As far as I know, the "worst" thing that could happen by dirty flashing is an unrelenting boot-loop. In those cases, you should just do a full system wipe and re-install the ROM.
I recommend, as Micmars does, a full system wipe prior to installing any ROM, but to each their own.
Typically, ROMs do not install different modems. As far as the MJ4 vs. NAB vs. NC5, here's a little primer on the various versions:
MJ4
This was the last Jellybean TW released for the Sprint Note 3. If you are on MJ4, you'll have to update your bootloader to NAB (or NC5) in order to update to KitKat ROMs (and you can't go back). The
NAB
This is the first KitKat TW ROM for the Sprint Note 3. Once on NAB, you can't go back down to Jellybean (yet... some people are working on it). You need to be on the NAB or NC5 bootloader in order to flash these ROMs.
NC5
This is the second KitKat TW release for the Sprint Note 3. It introduced some updates to the system and it includes WiFi calling (I've never used it, but others say it's really nice). You can flash back and forth between NAB and NC5 ROMs as much as you want, without changing anything. You need to be on the NAB or NC5 bootloader in order to flash these ROMs.
As far as updating to NC5 ROMs, just look at the changelogs between the NAB and NC5 versions of the ROM. If the added/changed features look appealing to you (or it looks more stable), then by all means update.
As far as modems go, I always stick to the newest Modem, which always tend to work best for me (I'm in a large metropolitan area). Sometimes people will report that the older modems (MJ4 or NAB) work better in their area. The Modems are completely separate from the ROMs, so flashing an older (or newer) modem should not have any affect on the stability of the ROM. It's really up to you if you want to update it.
As far as bootloaders go, if you are already on KitKat ROMs, I'd recommend updating to the NC5 Engineering Bootloader, but as long as you're on NAB, you should be fine. Just make sure to read the OP of any ROM you flash, they typically will tell you what version of the bootloader you need to be on.
Hello guys, I am on stock mk2, 4.3 with root, and I just downloaded safetrap 3.71 haven't installed it. Im familiar with flashing via twrp, however Im not sure which method to use. There are alot of different methods from downgrading to upgrading. What is my best option? Will i need to update modem+kernel?
i can only recommend visiting my thread and downloading 1 file upgrade. either the Complete Package which has all the apps modems modules ect you'll need or just the NC2 or NC5 1 file upgrade you flash in Odin 3.10 for the safest and easiest upgrade possible since your already on 4.3 rooted with safestrap then you don't really need to worry about downgrading as you shouldnt have to downgrade. Just avoid OTA/Full System Odin Flashes and well anything with bootloaders in them... at least thats what I'd do if I was you

You don't have to act like an asshole. There's no need for that. I've had plenty of people tell me the method I wrote up was easier to understand.

I was particularly looking into this method: 1545_MK2toNC5_KeepRoot http://forum.xda-developers.com/showthread.php?t=2749660
why is it bad flashing this OTA? Also just from reading posts, if I flash full nc5+root i had to flash modem + patches? or am I incorrect? This phone is going to be for someone else, So i want to stick with stock + root as much as possible. One key feature it must have is wifi tethering.
Also, what method are you suggestion I use in your post. method1 or method2?

That's the way I did it (munoz_ri's I545_MK2toNC4_KeepRoot), starting with clean MK2. One small flash and a reboot and it's done.
If you're starting at MK2, that's the fastest way to go.
If you're starting at NC5, use Surge1223's or Gigilie's upgrade. techguy2002's directions are easier to follow than Gigilie's IMHO.
Here's some very well written instructions for gigilies method: http://forum.xda-developers.com/showthread.php?t=2769480

Shouldn't we ask if the op wants to keep an mk2 bootloader or wants stock nc5 at this point? Different files produce different outcomes.

I didnt know. I just finished flashing the ota and seems to work fine, apart from getting auth issues from hotspot. But this phone currently doesnt have service(activated) so i cannot test the hotspot. But things seem to work well. Whhy would i need a different bootloader, and how can i tell which version I am on?

Mk2, NC2, and NC5 are all valid bootloader as well as ROM bases and it might matter which combo you have if you run into bugs down the road.

I just linked to @Surge1223 's TetherEnable zip in my OP and added flashing instructions.
