Hey guys
First, I am not a U.S resident, my phone is unlocked so I can work with it here in Morocco with IAM carrier SIM .
My phone is an S4 4G SPH-L720 ( Sprint ), when I bought it, it was on I9505 ROM ( I changed it due to Wi-Fi Smart Mode can't switch it off but 4G was WORKING FINE ! ) and under the battery, it's written " GT-I9505 "
Now I am using an official android 5.0.1 ROM . 3G is working fine, but when I select LTE/CDMA, and after reboot, the phone lose signal, no signal at all !
I tried to flash the last official ROM, but the same problem.
VERY IMPORTANT information ! In Morocco, 4G bands are " band 20 " and " band 3 "
and SPH-L720 supports LTE " Band 25 "only .
is there anybody can help me fix this issue, please !

It doesn't work for me either. But I'm on a custom rom.
What if I try a CM ROM ? Is it going to fix my 4G problem ?

You can try.
So in the end what kind of model is it?
Don't trust stickers and such, they may be wrong.
You can trust only download mode.

The Download Mode shows SPH-L720.
What I don't understand is at first, it was on a Lollipop 5.0.1 for I9505, how is that possible ? Because when I tried to flash an official ROM 5.0.1 for I9505 using ODIN, it failed. Is this means that it was running on a custom ROM for I9505 on my SPH-L720 ? this is confusing.

Odin sometimes fails for other reason (USB cable, USB port on the pc or Windows version).

I guess not, I flashed it many times with the same cable, same pc and the same windows version. It's 100% ROM problem. This means that I can't flash I9505 ROMs because my phone model is SPH-L720.
But it's okay, the main problem that I have now is how to make the 4G works again ! I also tried official android Kitkat 4.4.2 and still no signal at LTE/CDMA mode. And my living area has a 4G network of course.

I found an important information , in Morocco, 4G bands are " band 20 " and " band 3 "
and SPH-L720 supports LTE " Band 25 "only .
Is it possible to add one of the two bands that works in Morocco ?

I found this thread http://forum.xda-developers.com/galaxy-s5/general/how-to-add-rf-lte-frequency-bands-to-t2886059
But I need a working Custom ROM with Kernel to do that for SPH-L720.
If you have a good Custom ROM with Kernel, please write back =)

Every ROM comes with a kernel included.
Does it have to be a custom kernel?
You can try JDC Team ROMs. Their custom ROMs come included with a custom kernel (alucard kernel).
nvm

Try to reflash Rom with full wipe if you didn't do it that way. Fixed it for me with no need to flash modems or kernel.

You can jack up your whole efs, partitions and everything when flashing if just one little thing is off. Can you restore your previous rom and make everything work?

Flashing a new rom probably won't fix it, bit of you want to try, bobcat ROM is the best one in my opinion.
i flashed a new rom .. searching for a solution all over the whole google
still not registered on network

There are a lot of topics about "imei/baseband = null/null" in the forum. And also the solution.

Which rom where you on before this problem?
Were you on Xnote for 4.3 ? and you updated to stock 4.4.2?
If that is the case, I recovered mine.
Hi guys I have a problem with my S5 G900F. I can use it only in wifi mode. When i turn it off the network doesn't work. Also i can make call but after that i lose the signal and can't do anything. The only solution (that sometimes work) is to turn on/off the airplane mode to get back the signal or reboot the phone but the network doesn't work in any case.
I already tried about 4 different rom (and flashed also new bootloader and new modem) but nothing worked. Please help me because i'm goin crazy with this !!
Thanks a lot

If the label under the battery says sm-n9005 and download mode says sm-n900s, it appears that you have a "frankenphone" whereby the phone is put together with different parts from different models of the Note 3.
Is this the ROM you tried to flash: https://www.sammobile.com/firmwares/galaxy-note3/SM-N900S/SKT/download/N900SKSU0GPI1/98062/ ?
Did you perform a factory reset after flashing the phone but before booting the phone for the first time?

If everything works on a stock ROM, you try flashing TWRP using Odin. This will allow you to backup the existing ROM and flash a custom ROM.
