Is it just me, or is the download for Joseph230_V1.0__Fenny_V1.3_STOCK_M919NB4_for_I337 NI1.zip missing? I'm probably just completely overlooking it, but I might not be.

Post #2 ( Prerequisites ) look at number 5.
[AT&T Samsung Galaxy S 4 General] extjsguy:
I really appreciate OP taking time to write these detailed instructions. I have one concern can you please help

I have rooted ATT galaxy s4 with NC1 and safestrap installed (with busy box)

Followed instructions for "Convert it to Tmobile Phone" (coz I do have NC1 already)

after booting up I installed ATT_NC1_modules.zip.

I let the phone rest , update and 2-3 reboots but I don't see wifi calling anywhere :(?

UPDATE: Though I am on NC1 I went though all the steps and it works like a gem now.Are the steps similar for Nj4/4.4.4

Thank You!!!!!!

THANK YOU SOOOO MUCH FOR POSTING THIS INFORMATION!!!!! I WAS MINUTES AWAY FOR SELLING MY PHONE UNTILL I STUMBLED ONTO THIS THREAD. IT WAS EXACTLY WHAT I NEEDED!!!!!. I had bought an SGH-i337 off of craigslist and went to a shotty corner phone store to get it sim unlocked for tmobile due to me not having a data cable. Turns out they had no idea what they were doing, and completely messed up my phone. The wifi would not work, settings would crash, yet I had a frustrating t-mobile unlocked sgh-i337 . I followed you'r instructions to the T, and it fixed everything!!!! Your the man! Props.

[AT&T Samsung Galaxy S 4 General] BigBirdie:
Works like a charm

Thanks again for the write up. I now have T-Mobile 4.4.4 running on my old AT&T phone.

As an FYI for others.

I had to load the "I337UCUFNJ4_100%_Stock_Rooted_ROM" as the, loading the kernel method, did not work. the OTA kept failing, as though it was not meant to upgrade the version I had. I even went back to NB1 and tried but that also failed.

I am still curious on the loading of Sickness ROM and Hyperdrive that are on the T-Mobile S4 forum.

Will they work or is this a special ROM, modified to work on AT&T/T-Mobile?

Thanks again for sharing!

:good: :good:
[AT&T Samsung Galaxy S 4 General] joseph230:
Yes, You can load 4.4.4 ROMs. BUT make sure to replace the "update-script" in the ROM that you want to flash with the one that comes with my ROM (which is under M919_NH7_for_I337_NJ4.zip\META-INF\com\google\android). The script in my ROM is modified to not mess with ATT official kernel that is installed on the phone.
[AT&T Samsung Galaxy S 4 General] BigBirdie:
Thanks once again.

All is working. :D
[AT&T Samsung Galaxy S 4 General] BigBirdie:
I modified "insane hybrid V6" and removed, "updater-script" and replaced with the one in your rom

ui_print("* KK 4.4.4 M919_NH7_for_I337_NJ4 *");

ui_print("* by Joseph_230 *");

ui_print("************************************");

It loaded OK but I lost wifi, which was the problem before replacing the updater-script.

Any ideas on how to fix wifi with "insane hybrid V6" ROM?

thanks!
[AT&T Samsung Galaxy S 4 General] joseph230:
To fix the wifi issue you need to flash in NJ4 modules. Here is the link.
[AT&T Samsung Galaxy S 4 General] BigBirdie:
Thanks AGAIN!

That fixed it.

Now my obsession with loading ROMs can continue! :D
[AT&T Samsung Galaxy S 4 General] extjsguy:
thanks Joseph..4.4.4 nj4 works like a charm. you rock.

As mentioned in earlier posts for insane rom.

I have to install insane v6 rom (I believe it is on nh7) and then flash nj4 kernal ?

Thanks
[AT&T Samsung Galaxy S 4 General] joseph230:
Rule of thumb:

The kernel module that you install depends to the kernel that you have on your phone. If you are on NJ4, after installing any 4.4.4 ROM you need to install the NJ4 kernel modules. another example, if you are on NB1, after installing 4.4.2 roms, you need to install NB1 modules.

have fun rom flashing :)
[AT&T Samsung Galaxy S 4 General] bonchien:
joseph230, could this be modified to get the fenny ROM working on an i337z, Cricket/AIO Galaxy S4? The phone's rooted and has TWRP backup installed. It came with 4.4.2 and has an ND3 kernel which isn't a standard AT&T kernel. I've flashed custom AT&T ROMs to the phone, have Goldeneye working on it now, by not flashing the kernel. Can I pull the needed kernel files from a TWRP backup to modify the ROM or flash the kernel files after flashing the fenny TMO ROM? If so, which files would I need to pull from a backup?
[AT&T Samsung Galaxy S 4 General] bonchien:
T-mobile ROM working on Cricket/AIO i337z

I figured out how to get the i337z ND3 modules from my TWRP backup and apply them to a zip that can be flashed. I then installed the T-mobile ROM and immediately installed the ND3 modules in TWRP recovery. Everything went swimmingly, and I now have the T-mobile ROM running on my Cricket i337z. For anyone interested, I've attached the i337z ND3 modules, plus the i337z NE2 modules created by devzero in this thread: http://xdaforums.com/galaxy-s4-att/help/i337z-cricket-variant-modding-t2817179, which I believe is a newer build than the 4.4.2 ND3 modules.

p.s. Us i337z users shouild be able to flash any Galaxy S4 TW ROM using these modules.

p.s. What modem were you on before flashing? How did you flash the ROM? Did you use TWRP, advanced wipe, then flash the ROM then flash ND3 modules?

Changes from Fenny-UVUFNB4-STOCK-ROOTEDv1.3

Thanks for the work.

Can you elaborate on the changes you made from Fenny's ROM? The obvious one is modifying the updater-script so it's Safestrap friendly (i.e. removing line 3, below)

format("ext4", "EMMC", "/dev/block/mmcblk0p16", "0");

However I saw many other modifications as well. (full details in attached diff.txt)

[AT&T Samsung Galaxy S 4 General] destructionj:
Thanks for this, this is a great thread. I found that after installing the T-Mobile rom that the 1700 band (AWS) was not open on the phone. It seems that most of T-Mobile is reframed by now anyway but I thought it might be worth mentioning and answer the question for those that were wondering.

To enable the AWS band, a modem edit was still required after performing these steps. If your using the newer roms then the method is a bit different then the MF3 and older modems.

Depending on how new your rom and build are will determine the appropriate method used to complete the AWS unlock procedure.

If your running Joseph230_V1.0__Fenny_V1.3_STOCK_M919NB4_for_I337N I1.zip then you can Safestrap a RockRat MF3 modem into the phone and do the older AWS edit method. Keep in mind that you must flash the modem back to MF3 for that method to work. That older method will only work on modems on or before the MF3 build.

That being said, if your on the newer builds then the MF3 modem is not fully compatible ruling out the older AWS edit method and therefor you can try the newer AWS method.

If I flash to a T-Mobile ROM

Hello,

EXCELLENT GUIDE! I just aquired a AT&T Samsung Galaxy S4 running 4.4.4 (FNJ4), I have two questions regarding this guide. I'd like to be able to use this phone, SIM unlock it to use with T-Mobile, and then use the device as a "Wifi Hotspot" only more or less. If I follow this guide to convert to M919, will I then be able to flash T-Mobile M919 Galaxy S4 specific ROMS if not, what about MODS? The reason I ask is a lot of their ROMS have "unlimited/unrestrcited wifi tethering" built in, and I have truly unlimited data to do that with.

Long story short I have 2 questions:

What do I have to do, to use this device with T-Mobile, and have unlimited/unrestricted WiFi tethering?

Will I be able to flash roms built for M919 after following this guide?

Keeping MDL bootloader

Fortunately, I have the MDL bootloader and would like to upgrade from 4.4.2 to 4.4.4 rom. Can someone offer advice on flashing NJ4 modems, firmware, and a 4.4.4 Tmobile ROM without compromising the MDL bootloader. I have not seen any specific paths to do this without loosing the MDL boot loader.

Looking for this for few months and found your post. Great post and thanks. Just followed the steps and worked without any issues
[AT&T Samsung Galaxy S 4 General] JeepinxJosh:
There are lots of post with the NJ4 modems and kernels you can flash... just don't flash a complete firmware with a bootloader.... As long as you don't flash a bootloader your fine... you can flash kernels, modems, modules, roms.... just not the bootloader so no complete firmware upgrades unless someone specifically took out the boot loader which you can also find for Nj4 I have all these files and got them from this forum. Just search for them. If you can't find them let me know I'll pm you a link or two

My problem is I want to stay on att I just want to use a t mobile rom cuz the tmobile roms are cooler looking and no one seems to wanna help me with that lol

FROM WHAT I'VE READ AS LONG AS YOU FLASH THE KERNEL AFTER IT SHOULD WORK BUT FOR EACH ROM THE INSTRUCTIONS are a little different... what I do know is always flash the kernel and modules to make sure calls data and wifi work... and make sure that if its a 4.4.4 tmobile rom your on NJ4 as that is also 4.4.4

Loading TMO ROMs - what needs to change?

I have tried several of the TMO ROMs and only one has worked so far. One of the Sickness one.

I am unclear what needs to be changed for them to work. The last one I tried I copied the updater-script as per previous instructs but it failed looking for wallpaper.

What other TMO ROMs are being tried and what did you do to make them work?

I tried the Golden eye Lollipop, 4.4.2 version. It has AT&T Safestrap options in the Aroma setup.

Still failed for me and had to go through the ODIN setup.

I am getting pretty quick at getting ready for the ROMs, not so good at getting them to work.

V2 and V# was best... then Dark Carnage and deadly Venoms worked also... also the Sickness V5 mods I use with every Rom I use and I'm back on ATT NJ4 running MD 1.2 NJ4 Stock minimilist... all you need to do is Flash the kerel for your provider and the Modules for your proper baseband and they overwrite the Tmobile crap... simple stuff.... LMK if it works for you or not and I'll get more detailed if needed.... use the normal install way that they all use... and for me at least I didn't need to worry about any magic tool kit cuz I flashed the ATT stuff over it anyways...

***From Diffrent Thread but now you have links for 4.4.2 and 4.4.4 from MDK all the way to NJ4 and I even provided the NJ4 file at the bottom ***

I know it's thier own fault for not reading a few posts and all but you should really update the OP so people don't get stuck in bootloader like they are still... this is working perfect for 4.4.4 nj4 and the first quote is for 4.2 mdk - nc1 which all work if done the way explained above...

I read the thread and some one else had the similar problem. Can we downgrade the rom with locked bootloaders. We were able to install the initial roms and able to boot. But when we install TMOBILE rom it is not booting.

how do we check the phone has locked boot loader.

I was initially on android 5.0.1 which is from AT&T and I did not check the build version before I start the process. Does 5.0.1 has locked bootloader. Or KNOX boot loader is causing the issue ?

FINALLY I WAS ABLE TO INSTALL M919 on I377 using these instructions. The 4 attempts failed because of various reasons. But the main reason why it did not work for me is because of BusyBox installation.

I think in 2014 version of BusyBox it installs thebox on /system/sbin folder. With the current version (July 2015) from play store by default installs on /system/xbin. We have option to change this while installing the busybox. I make it to install uner /system/sbin folder.
