How do I go back to stock? Not stock modem.

Okay so I want to flash back to stock but I realized that my bootloader is not the stock one. I flashed the modem to the newest one before. My bootloader is I747MVLUEMK5. I've heard people sat that i cannot go back to stock just straight flashing with Odin now that I have a different modem. What procedures do I need to take to flash back to stock?

EDITED: This post was erroneous terrible advice. See latest post.

Alright, Im a bit perhaps... Noob at this? So I can just get the stock file and flash through Odin with no worries and no need to flash or do anything else? Thanks for the reply.

I apologize. MK5 is a problematic bootloader. Do not try to Odin flash an older firmware over this. Again I apologize. What carrier are you with? If it is a Canadian carrier you can just flash the appropriate firmware from here: http://forum.xda-developers.com/showthread.php?t=2558311. These have the bootloader removed.

Alright. I already have a stock ROM before and the name of it includes MK5 for TLS. I'm thinking that would work? The exact name is "I747MVLUEMK5_I747MOYBEMK5_I747MVLUEMK5_HOME.tar.md5". No problem, good thing I didn't flash it LOL. Thanks for your help.

That is the correct one, Backup everything you need off your phone as Odin will wipe everything. nLeaving an external SD in is OK, but the internal memory will get wiped.

Alright. I was on Quantum but I find that the newest version is far too glitchy and incomplete for me. Any other ones you recommend? How about LiquidSmooth?

I've only used stock and CM11 so far since 4.3. The I've not tried Liquid Smooth but Grievous ROM is pretty good. It's the ROM currently on my wife's phone. It is white themed Touchwiz which was my biggest selling point.

I don't think that is compatible with the i747m no?
Oh and also, let's say I want to get Liquid Smooth onto my phone but I currently have Quantum. Do I have to flash back to stock with Odin and then install the Liquid Smooth ROM? Or can I just go and wipe the system now in recovery without going to stock and then install Liquid Smooth in recovery?

Grievous is compatible with the 747m. Im on 747m Bell. You just need to flash a modem and kernel to get data and wifi to work. As far as liquid smooth, you do not need to go back to stock. Installing the ROM and then wiping should work. If you do find that you ever flash a ROM and have WiFi issues, kernel is likely culprit. No data is usually due to a modem. These seem to be more often with new ROMs and most development based off AT&T phones.

[Q] 4.3 rom on 4.2

quick question.
i have a stock rom (4.2.2) tmobile galaxy s4 with the ktoonz kernal, and i want to flash wicked v10 to it. wicked is a 4.3 rom, and im not trying to brick my phone.
ive been searching for a little bit, and i keep finding talk about flashing a bootloader and radio, or using odin to download a new modem... but i have yet to find any solid answers when it comes to this on the tmobile gs4. can someone provide some insight?

You shouldn't have any problems flashing Wicked V10. I'm still on the MDL bootloader and used a variety of 4.3 and now 4.4.2 ROM.
You might want to update your modem however (If you're getting data drop when screen off, if not no worry).

You shouldn't have a problem. I went from rooted stock 4.2.2 straight to flashing 4.4.2 and the NB4 modem all while still keeping the MDL bootloader. Just follow the instructions in the op after reading the rest of the comments.

[Q] Signal drops when on a call with any kitkat rom

I am having a weird issue with my S4 running any Rom past 4.2. When I make a call, the signal indicator changes to the circle with a line through it. The call stays connected, but no data transfer is possible. Any attempt to access the internet results in an error. But the call stays connected just fine. Once I end the call the signal eventually comes back and I can use the phone as normal. If I try to make a call before the signal comes back I get an error (even though I was just on the phone). Rebooting the phone seems to make the signal come back faster.
Any 4.2 rom does not have this issue.
Anyone have any ideas?

Somehow the new baseband has made things MUCH worse. The phone is completely unusable now. It is EXTREMELY laggy. no sounds from screen touches at all. It didn't even do the t-mobile jingle on boot. When I try to make a phone call, the other phone rings before the S4 leaves the "dialing" screen. Talking doesn't work, no voice gets through in either direction. I would never expect this from a modem flash.
I can confirm on the about screen the new baseband is M919UVUFNB4
I tried wiping the phone, thinking somehow it needed to "start fresh" with the new modem. That did not help. Then I tried reflashing Fenny's 4.4.2 Stock ROM (same rom I was running before). Nothing helps.
What the heck is going on?!?

Sounds like you installed the NB4 LTE modem as well. (NON-HLOS) i think is the name. You only need to instal the actual modem as the LTE modem will do exactly what you are experiencing

You are exactly right. The modem tarball I downloaded had both, so I flashed both (woops!). I just finally got myself sorted out. Had to flash back to factory 4.2, re-root, install TWRP, re-flash 4.4.2, then flash the modem.bin (several times before it took). But! All my problems are resolved.
Thanks for the help guys.

Flashed the modem previously linked in this thread, and Fenny's 4.4.2 stock rooted rom. Can't really compare battery/signal because I just flashed it, and it's my wife's phone. She got it when I got the S5

[Q] What do I flash to get SGH-M919 working again?

Hi xda, I hope your Friday is going well.
EDIT: My calling problem was not fixed. I reflashed 4.4.2 NB4 Modem (twice to make sure it stuck) and the calling still does not work. Did something just completely fry when I had CM11 on this thing? Any ideas anybody? I don't even hear a dial tone if I am the one dialing out, the call still goes through though.
Everything below was my original post which has been resolved, didn't want to start a new thread though.
-----------------------------------------------------------------------------------------
TL;DR: My T-Mobile Samsung Galaxy S 4 (SGH-M919) is unable to boot stock rom, and I am unable to enter recovery. I get seandroid messages trying to do either. Fortunately, the phone can enter download mode. What do I need to do or flash to get this phone booting again? Thank you in advance for taking the time to read and help out.
Below is the long story with details:
1. The phone was given to me running stock Android/TouchWiz. Unfortunately, I do not know what version but I assume it was whatever was the latest version as of late April.
2. I rooted the phone using Odin and CF Auto Root.
3. I created a backup of this newly rooted stock rom.
4. I flashed Cyanogenmod 11
5. After a while I discovered that I could answer calls but I could not hear nor be heard during the call.
6. I restored to the stock rom using the backup I made in step 3.
7. The calling issue continued, so I figured I would just unroot and go back to like-new factory settings. This way I could take the phone in to be repaired or whatever.
8. Following this thread: http://forum.xda-developers.com/showthread.php?t=2336392, I attempted to flash k0nane's UVUAMDL Official Tar
9. Odin got stuck connecting to my device, I believe it was because I did not run Odin as admin. I pulled the battery and repeated this step while running Odin as admin.
10. The flash was successful, however during the phone's first boot it got stuck on the T-Mobile splash screen for about 30 minutes or so. I pulled the battery again.
11. Anytime I put the battery back in the phone, it will attempt to boot and hang at the T-Mobile screen, I believe this is a boot loop?
Looking online, people suggest going into recovery and wiping but I cannot enter recovery. I just get the seandroid not enforcing messages. I'm very hesitant to keep looking through the forums and trying things because I feel like I'm on the edge of bricking the phone if I haven't already.

I don't think the flash was successful because it wouldn't give you those messages, and you would need to flash either 4.3 or 4.4.2 not 4.2.2 (MDL) Try flashing a newer firmware version.. If it was updated to the newest then I would try 4.4.2

Ok so I flashed the wrong rom then. I hate to ask but where could I find a 4.4.2 stock rom? I just found a rom I believe will work but the file is titled "M919UVUFNB4_M919TMBFNB4_TMB" not sure if this is 4.4.2 or newer?

This is where I obtained the rom above that I wasn't sure was the newest.
I flashed this rom and everything worked, thank you both.
Any ideas on what happened with the phone call issue? My friend that gave me the phone said it was working just fine when she had it, so I assume somehow the rooting or CM11 screwed something up? Weirdly, calling through WiFi works just fine.

The only thing that can foul up your phone like that would be a bad cm flash or preflash, it's super important to read and read again, check the thread for support from members and resolutions to problems before you consider the build for your phone. Ask questions and double check everything before you take the plunge.
I assume that the calling problem is fixed, a corrupt modem may cause that and re flashing the modem will correct this.

My friend gave the phone to me. She got an S5 and didn't want to bother with selling this S4 so she just gave it to me. It was completely pure and stock, with calls working. Something screwed up during the CM11 flash I guess.
WiFi calls still work, everything works except calls.
Maybe I'm doing something wrong? I flashed the sammobile NB4 tar twice via PDA in Odin as usual. For the modem, I flashed the modem bin via Phone in Odin twice. Thank you for your help, by the way.

New term for CM, "complicated maneuver" ,.
Reflashing firmware may do it. Can't hurt either.

I flashed both Fenny's firmware and a baseband he also provided. Did both twice, and calls are still not working.
I was doing some research on this whole "Radio: Unknown" thing and I started seeing threads talking about flashes corrupting the phone's EFS partition. I never made a backup of mine, so I have nothing to restore to. Is it possible that I could use someone else's EFS backup and then use it to restore my phone's EFS partition? Does it work like that?

Flashing modems and such with a custom rom installed often fails. Did you try doing a restore to full stock using Odin?
It sounds like the phoen has Android 4.4 on it already so you will need to flash the full 4.4 package (can't go back to 4.3 or 4.2)
Try and, boot hte phoen without modifying it, and see if calls work then.
The EFS thing is about the IMEI number. Does your device show an IMEI number in settings? If it does, your EFS isn't the problem. If it doesn't....well then yeah. Problem is pretty much narrowed down.

I have restored the phone to full stock and have been using it that way since I started this thread. Everything is just like fresh from the factory (except for the knox counter being tripped obviously). Calls still didn't work. An IMEI number still shows up the phone's settings. Using WiFi calling hasn't been that bad at all, but I'm screwed in the case of a real emergency with this thing.

[Q] Should I upgrade my modem?

Hi All,
I just recently returned to my trusty T999 Galaxy S3 and was wondering what modem I should update to? I just flashed CM11 and everything appears to be working properly except it says 3G in the status bar and not H+ (even though I'm in an HSPA/LTE area).
Currently I am on modem T999UVDLJA, which I believe is a 4.1.1 modem. Should I update to a 4.3 modem?(if so which one?) or stick with the 4.1.1 modem? I've read that once you update to a 4.3 modem you can't go back to 4.1 modems? Is that true?
All recommendations are welcome.
Thanks!

Once on 4.3 firmware you cannot use older modems. If on pre 4.3 firmware you can try the 4.3 one and go back if needed.
First, though, start a large download using mobile data. Go to settings, about device, status, network type. This will tell you your true connection type.
If hspa is not working, its much more likely to be a tower issue than a problem with the modem. Still, it doesnt hurt to try the other modems though!

LJA is very old, you need to update it so you can get H+ try the latest modem

Hi Doc,
You are correct, once i start doing a "large download" the data changes to H+ up top, so HSPA is working. Now with regards to pre 4.3 modems not working, I am running CM11 which is 4.4.4 and am running the old UVDLJA modem. In theory is this not supposed to work?

What modems are everyone using right now with the 4.4 ROMS?

Doesn't matter what rom you are on. Its the base firmware. If you have updated to 4.3 firmware, you must use the same or newer modem as the firmware build.
If running non touchwiz kk, as I understand it you can do so on older firmware. To run a touchwiz kk rom though, you must be on 4.3 firmware and thus a 4.3 modem.
You are using a non touchwiz rom, so as long as you are not updated to the 4.3 firmware, you can run the LJA modem without issue. Once you update to 4.3, you will have to use the 4.3 modem.

I remember there were certain modem versions that wouldn't work with hspa, must have been ICS then..

Is it safe to update to a 4.3 modem? Will it "brick" my phone and/or lock it with KNOX?
Which 4.3 modem should i update to?

If you want to update to a 4.3 modem just flash the latest, and it won't brick or give you Knox

Im sure the app serio22 mentioned will work fine, but I always tell people to do this as ive learned you cant always trust what an app or gui tells you!
In terminal emulator, enter this:
getprop ro.bootloader
What it returns is your base firmware build.

That's what I use to tell people as well but they were always confused on how to use it and read the info so I just started mentioning that app instead.. I'm not sure if it works on CM come to think of it. What I like about it is that it gives you tons of info, even how many times you've plugged into the headset jack, and charger! Lol
