help

Noob here, so please be gentle. I tried doing your Odin double flash method with both of the modems (one at a time) in the phone (ct) slot, and it didn't seem like either of them gave me 4G capability, triband/spark or even normal LTE. I'm pretty sure my location has 4g, but there's a chance it doesn't. Can you guys help? I'd really like to get 4G working on my phone. 3G is working, and WiFi. There's also a chance neither of them flashed correctly, I will try again tomorrow.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] shadowcliffs:
Are you sure you odin flashed the right rom? It seems you flashed a cm rom instead of a stock rom. Anyway, no matter what rom you are on, you might want to check the apn.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bthorne79:
What modem did you try flashing also check your area has 4g a modem won't just make LTE work if it is not available. And the modems go In to the cp slot if WiFi is not working with CM flash my stock root that matches the baseband you flash let all radios connect and check WiFi go to mobile settings select auto let it update profile and do a prl update you should be good to go you might have it set to CDMA only
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] wpaulstate:
Yeah, Oops. I don't know why I think being on a completely different rom and kernel wouldn't be a factor... :eek: ... didn't realize i would have to set up APN, whops, Ill do that now. Thanks for helping me troubleshoot.

---------- Post added at 03:58 PM ---------- Previous post was at 03:34 PM ----------

Wifi is working

.Well yep, theres one problem solved, hahaha it was on CMDA. Still no 4g, so I'm using idone's GalaxyTools, and then setting up the APN, but it doesn't look like its saving...

So I will have to flash stock to update PRL and profile? :crying:

Can I flash CM again once they have updated? Not a big fan of the slow, bloated stock rom.

Thanks for your help. I am slowly learning.

Also I am on Clockwork recovery, which doesnt seem like you reccomended it for the SPHL720T..
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bthorne79:
Why do you need to set up apns if you are not on a alternative carrier they are built in

I also seen you are on cm11 might I suggest a better rom

I don't know I just figured they could be causing the problem. I will flash the stock NC6 rom, see if I can get everything working on that properly, and then I will try out your OCT-KK rom.

I have a horrible situation that I need help with. I am stuck on the Samsung logo boot screen on my Samsung Galaxy s4 L720t. I some how erased my backup recovery as well. Here is the information I have to provide about my phone:

I had the phone in recover ready to wipe everything; wiping the cache and doing a factory reset. I did this because I was preparing to flash a rom. I went ahead and rebooted my phone to be sure it still operated properly but all it did was get stuck on the Samsung logo screen.

I attempted to do a recover from adb sideload: I get the following errors: Error: closed and dns server failure. So basically the only option I have available is using odin. Would anyone be willing to advise me on what to do next? I am obviously not an expert. So any help from you all is and always has been appreciated.

---------- Post added at 03:47 PM ---------- Previous post was at 03:41 PM ----------

I would actually like to do that but can't seem to find any ATT based roms for Galaxy s4 l720t. Do you have any suggestions? I will attempt this after my phone is up and running again. lol
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bthorne79:
One you didn't wipe your recovery so you can boot back into it just do the finger button combo power and volume up from there you can adb sideload if you dont have a rom to flash in your SD

CWM is outdated use the latest twrp
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] fuzzybuffalo:
These are the stock firmwares for the 720T. http://www.sammobile.com/firmwares/database/SPH-L720T/

You can flash any of these from Odin and when you click on one of them it has directions for flashing.

If you are on an older bootloader and want to keep it, you can flash an older version. OA3 actually has a newer build date than NK1, I'm on OA3.

You will have to root again, but this is the method I use anytime I have problems.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] TheBeastJon:
Every firmware that I try seems crash odin.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] JerryGNYC:
And what's puzzling me is - I'm on NC6, and I just hooked up with Kies to backup some stuff. It then tells me the available update is NK1. :confused:
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] 2WhiteWolves:
Have you tried a different version of odin?
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] TheBeastJon:
odin 3.10.6 and odin 3.09.... Both the same results. Even crashes when trying to use the twrp tar md5 file. I have never had this to happen.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] fuzzybuffalo:
Yeah, we talked about NK1 in this thread, I don't remember what was said, but the build date being older made me decide to stay on OA3 and wait for LolliPop.

I have not heard of that either. The only thing I can think of is drivers or a conflict with Kies.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bthorne79:
Use a different cable
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] JerryGNYC:
I'll probably Odin OA3 anyway.

[MENTION=6307131]TheBeastJon[/MENTION] - I'm walking in during the middle of the show, but when my recovery got hosed a few weeks ago (my fault) I used the dd command as shown on the TWRP webpage for our phones, and it worked great.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] TheBeastJon:
I used a different cable and that didn't seem to work. I have read many of your posted threads so I can tell you have plenty of experience. With all of the knowledge you have, if your phone was stuck on the Samsung logo and you didn't have a backup recovery (I did have a backup recovery but somehow deleted it in recovery in twrp.)..... What is the first thing that you would try?
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bthorne79:
First thing I would do is right to odin it is about the only thing you could do other than Heimdall which is a little harder to use for most or adb if you phone will show up. Use a data only cable for odin push recovery in PDA slot or Boot loader slot uncheck the boxes and flash if fails try new USB port most of the time error with Odin is cable or USB port if that fails than Odin back to stock with the same firmware. If you want I can link with Odin files I have
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] TheBeastJon:
I finally got it to work but thank you very much. I actually use the firmware that you have on your afh profile. Thank you very much.

---------- Post added at 10:36 PM ---------- Previous post was at 10:22 PM ----------

I didn't think that kies would cause any problem if the program wasn't running, but it turns out it does. After I uninstalled kies, odin worked perfectly. So thank you for mentioning kies.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] fuzzybuffalo:
You are welcome.

After uninstalling KIES, does one have to reinstall the Samsung USB drivers to use ODIN?
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] wpaulstate:
I'm on the latest twrp now, with your stock rooted deodexed rom NC6, and i have flashed the NC6 modem.bin several times through odin. I updated PRL and profile, and everything is working except for wifi... :( ... should i just keep trying the modem or could there be a different issue? looking forward to trying your OCT-OS.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] 2WhiteWolves:
Try to flash the NC6 kernel thru TWRP, see if that will get your wifi to work. It's in OP/1st pg.

Flash the nohlos.bin in the cp slot. I do have a stock root thread that explained this. The only thing that is flashable in recovery mode is the ROMs.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] JerryGNYC:
Oh, yeah. Thanks! (I wish ODIN was available for Linux...) :cool:
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] wpaulstate:
help im dumb

is nohlos.bin kernel specific or can i use the OA3/NK1 extra nolohos.bin? couldnt find one for NC6.

is nohlos the same as NON-LHOS.bin?

EDIT/UPDATE: I gave up with the stock rom, and installed CM 12s most recent nightly, I think everything is working now. It showed LTE and wifi is working, i will doublecheck everything and get back to you.

I can upload them later if need be I stick with the same firmware just for being safe. And TW is picky with the modems and firmware that's one reason I don't use it.

No. The drivers will remain.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] TheBeastJon:
I was surprised to see after using my l720t gsm unlocked to AT&T that I managed to pick up HSPAP. Isn't that basically 4g? I was also curious about the use of QPST with the l720t since this device is a Qualcomm device. Just thought I would bring that thought up. Seems interesting to me.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] JerryGNYC:
Sorry, I should have phrased the post differently. I know what WINE is, I've had my own Linux machines since 1996... :D Actually it would be nice if I could have it run on my AlphaStation 500 running OpenVMS (at work). Maybe if it still had Tru64 UNIX on it, like when we bought it... :silly:

I'm guessing you haven't looked at Heimdall in some time. It looks like the Linux version is now complete, along with a GUI front end for it. I wouldn't even think of trying to run Odin under Linux/WINE (frightening thought!). :angel: Thank you again, though!

EDIT: I'll give the Linux version a shot as soon as I can (probably next week) and report back.

Wifi issue after downgrading from Lollipop to Kitkat

Wifi is not working after downgrading from Lollipop to OA3 by restore from a backup. My phone has OA3 bootloader, OA3 baseband, and Stock kernel. I also flashed OA3 NON-HLOS.bin but that didn't fix wifi.

Looks to me like that pic is just instructions for setting up the apn. If that's correct, I find it strange that just setting up the apn would get rid of sim lock error.

I almost asked you earlier if you had set up your APNs yet, but I did not think that would get rid of a sim lock error.

A little late now, but I can tell you how to very easily unlock your APN settings using GT. Just change the default code and sales code to XAS..see pics

May also need to reboot.

As far as I know you can't get LTE using with another carrier other than Sprint. The best I get is HSPAP which is considered 4g. If I am wrong someone please correct me. I would like LTE if it is possible.

Cannot get internet over wifi

I have spent many hours searching and fiddling to no avail, so I have finally concluded that I need help from someone much smarter that I am. I connect easily to my home wifi (TP-Link TL-WR841N) and DHCP assigns me an IP address no problem, but I have no internet. I cannot ping the router (192.168.1.1) - fails everytime. I have done every modem/router/phone reset combination possible. My phone is SPH-L720T build NC6 and is successfully rooted. I recently did a factory reset, but my phone started having the problem before the reset as well. Is there a fix I'm supposed to flash after the factory reset that I have forgotten? Some signs point to the problem being in my network/router but all other devices are connecting to internet just fine. I need some help to know what to troubleshoot - I don't even know where to start at this point.
