Hi so I have the L720T on the Spark network. I managed to root and get CWM Recovery working. I was running and NAND backup when my phone suddenly crashed not sure if it died I'm thinking thats what it was I remember my battery being low. After throwing it on the charger for a while it booted up but the connection was dropping in and out like crazy and never got LTE. Ive tried flashing a few S4 ROMs not for the L720T and flashing the L720T TAR with Odin and nothing seems to get the network back to how it was. I definitely had full LTE before all this and a great connection. Not really sure what else to try I'm hoping someone else with an L720T can help me out here. Thanks a lot. @bthorne79

Alright i need some help. ive done as much google/xda searching as my eyes can handle and i still cant figure out this problem.
I have a Sprint Galaxy tab im rooted via Z4root.
by Screwing around with flashing new kernels i some how screwed my tab up and im stuck.
The tab is in an endless black screen to "samsung" boot screen loop. the screen keeps flashing from the beginning of the samsung boot screen to a black screen.
I can get it into Download mode but that is about it.
if anyone can help it would be greatly appreciated
That happened to me after flashing the AT&T stock ROM to my Sprint tab just to see what would happen.
I used Odin and flashed Download 1 - Stock, no modem - Sprint Only! from http://forum.xda-developers.com/showthread.php?t=869819 and that fixed it for me, then went back to ROTO JME v4.
I killed the modem intentially on mine to make it WIFI only, not sure if this helps or not.
What have you tried to recover your Tab so far?

THANKS a ton! that thread had all the info i needed to bring my paperweight of a tab back to life! thanks again Morolinith!
Is there any way to get 3G back on my tab? i dont care about gps.... only 3g
This is my 1st post ever because every question I've ever needed answered I've been able to find.Unfortunately I cannot find the answer to this problem. Since my Post count is below 10 I cant post the question in Kangabeans thread.
This is the ROM I am using
I rooted and flashed my phone 4 days ago and ever since then my wifi or mobile connection never go above 2 bars. Everything works except data cuts in and out fairly often which never happened before while i was using stock. I can sometimes get LTE but it mostly just says H and is really slow. I live right in the middle of downtown Edmonton and always had an LTE connection before so I'm pretty sure it is an issue with my phone and the ROM. I can also be standing right next to my wireless router and i only have 2 bars showing up for wifi.
I know some people had mentioned similar problems in the Kangabean thread with poor LTE connections but almost all say it is working good which leads me to believe its something I've done. My initial thought to fix the issue was to flash a new modem, specifically this one modem_CWM_I337MVLUAMDJ.zip{4/22/2013}(Canada) from this thread because everyone that was saying their LTE and WIFI were working appeared to be on an MDJ baseband. I tried flashing the modem and nonhlos through Odin but it failed with odin saying: Failed, Receive response from LOKE. I figured my best course of action was to try and reflash the MG1 Baseband but again i recived the Failed, Receive response from LOKE. Thinking i screwed something up i decided to try and boot up my phone and sure enough i was stuck in a bootloop. Luckily all I had to do was load up recover and wipe the cache partion.
Everything is back as it was before i tried flashing the modems, even the poor connection to WIFI and Data.
Does anyone have any idea as to how I can fix this or what I did wrong that caused Odin to fail flashing??
Pretty sure I just found my answer for why I cant flash the modem. Im pretty sure MG1 is newer than MF3 (correct??) and if your on MF3 Odin wont work
I was doing some thinking..... I have mobile odin pro Can I try flashing the MDJ or MF3 Modem and nonhlos files with it or will it too end up failing??

Wow hold on! Do you have telus sgh-i337m s4? If so then you don't need anything to do with mf3. Only att and sprint have lockedbootloader. If your baseband is MDB or MDJ then you don't need Loki and mf3 kernel, in fact you'll brick your phone if flash mf3 kernel on any s4 brought in Canada.
You shouldn't be going anywhere near MF3 on your i337m. MG1 or MDJ only for us Canadians
Thanks guys I wasnt sure If I could flash those without any problems so I was waiting for someone to reply to this thread before i tried going that route to fix my connectivity issue again.
Sorry guys,
I am a Canadian with a 1337m MDJ S4 running CM 10.2
I just wanted to double check that I am bound to ROMS made for MDJ. Cannot I not update to MDL?
There are a number of TW Roms that I would like to try to get my camera and multiwindow options back Like :
FoxHound GearEngine 1.3 AROMA OR Eclipse.
Your feedback would be amazing.
Thank you
Thank God im not the only one. Look at my thread http://forum.xda-developers.com/showthread.php?t=2455955
maybe we can find a solution together. Im using CM 10.2 but i live in Mexico son i had to flash my carrier's modem and it seems its coming back to normal but im not totally shure... still testing this modem (all info is on my thread)
Let me know if you find a fix... thanks

so i rooted my phone last night and after trying a few roms that didnt end up working (and yes i was using the right ones from the sprint s4 spot on this site) i wanted to just restore my backup. after doing that i have had nothing but issues. now i have no sound and my phone is having issues connecting to the sprint network. i would really appreciate if someone could tell me how to get my phone back to stock and unrooted so i can take it in to get looked at
We really need some more info to help you, but I am going to assume that you were on 4.3 and restored a 4.2 backup. That would explain the sound issues.
Try going here and Odining the 4.3 tar to see if that fixes things http://forum.xda-developers.com/showthread.php?p=47359331

My son just came and told me his Wi-Fi isn't working. It's MDL and rooted. I tried doing a factory wipe, tried a couple different roms and it still won't turn on. It's been awhile since I had to odin but I can't find a stock rooted MDL file to flash unless someone has any other ideas.

Use the nb1 tar instead

Why don't you flash the full mdl from samfirmware and reroot. If it is truly, mdl and you flash nb1 you will lose the ability to run custom roms.
Sent from my SAMSUNG-SGH-I337 using Tapatalk
Yeah, it's definitely MDL and was running ib4std's KK rom. I tried flashing task's AOKP, SHOstock's new rom....even formatted the internal sd and the WiFi toggle just won't turn on for any of them. Don't know what my son did but I'm hoping doing an Odin back to stock works.

Yeah, my bad I read your firmware as mld. Definitely don't use nb1. Sammobile.com is another alternative

Deleted - read it wrong
Got the one_click version to install and pass but WiFi still won't turn on. I'm downloading the Att version from sammobile now and will try an older version of Odin. Hopefully this zip can just be unzipped to a .tar. No clue why WiFi is not turning on, everything else seems to work fine.
Be open to the idea it may be the hardware itself--

My son had dropped it a few months ago and I had to replace the screen and display but everything was fine until a week ago. Oh well, at least I had an active that we weren't using. Guess I'll just sell it. Thanks to anyone that replied and tried to help. :beer:

Some good news I guess... Local little shop said they could fix it for $50 which is obviously worth it to do. I'll find out more tomorrow once it is apart to see what is wrong. Might be a ribbon cable wasn't seated properly after the screen was replaced but I'd rather have it done by someone that can guarantee it gets fixed

Reflash the NB1 tar file in ODIN and see if it works then. You can find it in the general section, either search for the thread or find it in the [INDEX] thread.

started working for 5 hours then returned same issue...
I used Odin to root it using Nc1 Then finished with J4 ...
im guessing this must be a problem many are facing. a friend of mine gave me a an S4 logic board i337m variant and it has the same issue i have tried everything from flashing new roms flashing stock frimwares tried different kernels modems nothing seems to work. i second this post to see if we can find a solution. my phone is a I337m and have flashed GOLDENEYE to get the lollipop experience a month before the official Lollipop came out for the canadien variants and i have not had any problems i was wondering if i made a backup with trwp and see if this might fix this problems and if it does i can upload my exact backup to help other. but i was wondering if a dev can help me out and see if this could be a possible solution.
In the same boat aswell
I gave my phone to someone to update it to lollipop GPE about 2 months ago.... wifi would work but my data connection would cut out the minute the screen shut off.... after contemplating going back to the guy.... i downgraded to hyperdrive kitkat rom witch gave me better connectivity but no wifi... I ve been living with that for up until now until I decided enough is enough and flashed the stock lollipop rom yesterday. still no wifi. whats even more frustrating is I cant find the file path thats being mentioned so commonly as the solution.... and yes I am rooted. Also wifi was working no problem before I updated..

Well last night I went from 4.4.4 back to 4.4.2 to see if thus would solve the wifi and blue tooth head ache. It all started working just fine and did all the way up till tonight then back to not working. I then resulted to cleaning the Wifi prongs on the phone and it worked again for few hours. Now the weird thing happens I put it back into the phone case and just from snapping it in it stop working AGAIN. I restarted the phone once taken out of the case and it was working so I think I'm at a conclusion it's a mechanical issue not software. Maybe the wifi circuit us faulty
I've had lots if Galaxy and worked on a few friends but this wifi and blue tooth crap us unbearable.
My Bluetooth is fine. My wifi broke after downgrading to kit kat so I know it works It just seems the wifi files are corrupted or missing. I'm sure it's simple I'm just not savvy enough to implement it
