[q] lost mobile connection help!!!! - Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot

So i was on sacs custom 4.3 rom with the mja modem not the bootloader i manually updated to mja and i was wanting to try the 4.4 gummy rom and was having problems with data so i flashed my old 4.3 rom back on my phone and now it says i have no mobile connection but i have data. i dont get it ive tried everything that i can think of ive tried prl and profile update i also tried calling sprint but they are closed ive tried restoring my old backups and i even used ODIN to flash completely back to stock nothing has worked can some one please help im not sure what else to do

I had something similar happen to me, so what I did was completely wipe everything including my internal SD. Then I used Odin to flash MF9 MODEM but I selected not to reboot on odin then when I saw that it had passed I pulled the battery and booted into recovery and flashed SACS V8. you can flash whatever even his 4.3 with the MF9 MODEM.

Bricked my Phone :(

I was using Kangabean ROM found in the development section for a few days but was unhappy with my wifi and data connectivity and was unable to solve it so I figured id try a new rom and see what happened. Well I downloaded and tried flashing Super nexus 3.0.
I'm a telus I337M and i thought I could flash this rom even though its ATT because of this thread, I flashed my stock kernel and then the rom, but when I went to flash the rom it failed instantly. So I than rebooted my phone and it hung on the bootscreen. I than wipe/factory reset and re-flashed kangabean rom and KTs kernal because i knew it worked. Everything flashed, I wiped cache/delvik after install but when i went to reboot TWRP said root is not detected....swipe to install superSU, but no matter what I do my phone restarts and always gets stuck at the boot screen.
I have access to TWRP and Download mode so I am currently downloading the stock rom and kernal. I also have my stock nandroid backup before i originally rooted and flashed a custom rom. Whats my best course of action to take? Do I flash the stock rom through odin than factory reset in recovery?
Thanks for any and all help in advance. I'm pretty "green" when it comes to this stuff so any help is appreciated
I'd use the nadroid backup first that way you don't have to worry about loading a recovery to the s4 or wait to download the firmware. If that doesn't work Odin stock.

Just to update you guys in case anyone else has my issue in the future. I tried restoring my stock nandroid, however when I went into twrp and tried to recover it but was unable to because it showed my sd card as empty.....I'm assuming because I somehow lost root access.
Unable to flash my nandroid I downloaded the telus stock rom and flashed it via Odin. My phone is now functional again as we'll as re rooted. I restored my files via titanium backup but I noticed one big issue. My wifi doesn't work...I can access the Internet via my data plan but not wifi. Any idea as to how to fix this?
I also notice this telus stock rom has a lot more bloat than what my s4 originally had when purchased from the telus store. Not that that's as issue cuz I can disable it but I'm just curious as to why? On the notification bar there is also an N beside the wifi symbol with its own wifi looking symbol that was never there before.....what is this??

[Q][HELP] Lost signal on 4.3 after reverting to 4.2.2

Hey,
Today in between flashing a new ROM i went back to 4.2.2 cm10.1.2, just to check some things out before flashing a 4.3 ROM that i was intending to do in the first place.
However after having reverted to 4.2.2 when i went and install the 4.3 ROM i noticed i had no signal, since then i've tried flashing the radio and boot from 4.3 Factory Image via fastboot, tried installing a different 4.3 ROM, all with no success.
What can I do?
Btw i still get signal in 4.2.2
Thanks.

Check APN settings?
How do I do that?
Also the phone app just crashes totally when I try to do anything with it, even entering airplane mode triggers that.

You should do a clean wipe before you flash 4.3 from an older version, do a factory reset and wipe the system partition, then flash 4.3 rom.
via xda app
It might have to do with TWRP.
http://forum.xda-developers.com/showthread.php?p=45323439
Try flashing TWRP 2.6.0.0 then proceed from there to flash your rom.
I guess i forgot to mention, i did a clean install, i factory reset before reverting.
And i have TWRP installed, I've tried several ROMs and in all of 4.3 ROMs i dont have signal and the Phone app FCs when i try to use it.
On that note, does TWRP Factory Reset wipes System Partition?
Factory reset does wipe system partition except /data/media.
Flash TWRP 2.6.0.0 (this version)
Factory reset
Flash Rom
Flash Gapps
Flash Modem
Flash Kernel
Flash Supersu
Wipe caches
Reboot
Btw, here is some insight on what to wipe in TWRP:

Oh I just saw your previous post, didn't understand it at first but now that I think about it I do actually have 2.6.1.0.
Ill try what you said and report back.
Thanks.

Downgrade kitkat

I searched the whole forum and couldn't find an answer.... I flashed the new KitKat official ROM with the radio and everything is working perfectly but I miss all the features I had on 4.3.1. So I tried to restore the backup I did before flashing and it stays stuck on the Google logo..... What did I do wrong or am I missing something?

Maybe you didn't do a factory reset to clear the cache. What method did you use to update to 4.4 and what method are you using to restore 4.3?
sent from xda premium app
restore via twrp and flashed 4.4 by wiping everything and flashed the 4.4 update zip with the 0.97 radio
you can delete thread now, i flashed the 27-84 radio and now everything is back to normal booted up to my recent rom thanx

Ive tried everything MF9/MJA stuck at boot

2 days ago i foolishly flashed to a stock rooted deodexed MJA zip from Cyanogenmod 10.2. (NO I DID NOT MAKE A BACK UP. I DID do a full data/cache wipe before i flashed) Things got really weird after that. Phone would not boot past the yellow sprint screen. I had a few different backups that must have been old so i tried restoring to an older Triforce MF9 backup that i had from 2 months ago. After that i was stuck on the triforce boot animation. I thought "maybe my kernel got mixed up when i tried flashing to MJA". Downloaded and flashed stock MF9 kernel NO LUCK.
Ended up using ODIN to install a factory stock .tar of MF9... same boot loop, cleared cache(this succeeded), tried clearing dalvik cache (but it failed). It booted up and YAY stock MF9 WITH ROOT. So after all the sprint bloatware loaded up i was prompted for an OTA 4.3 updated. I foolishly accepted. So my phone shuts down into recovery installs the update then goes to CWM and says "fix root? yes or no" i hit "yes". Since then NOTHING has worked.
I tried to ODIN back to MF9 again as mentioned before, nothing. I thought it may be a kernel issue, I found no info on the new MJA kernel. I successfully used ODIN to flash philz recovery.tar so now im on philz instead of CWM or TWRP. I attempted to flash the original stock rooted MJA.zip that got me into this mess, but no luck. I now can not get passed the "Samsung Galaxy S4 screen" (tried clearing caches, and battery pull too). Im downloading "KERNEL-SPR-L720VPUEMJA-1382157965.tar" & "SPR-L720VPUEMJA-20131030154609.zip" at the moment to flash with ODIN. Also i might add, it seems like any recovery i use, TWRP, CWM, Philz they dont fully install the rom .zip's. I hit "install zip from ext/sd-card" and its like a 2 second installation. NO MATTER WHAT ZIP I TRY. Kernels seem to flash okay.
I dont care about root, or knox. I just want my phone again lol.
Try going here

you need to try to install the Triforce MJA/4.3.1 kernal/MJA modem all at the same time. IDK what happened on the first try to boot loop you but once you updated the modem to mja you can't flash MF9 modem/kernel on top of it. Try that and let me know.
