Good afternoon,
I recently updated to 4.3. It was the OTA update for sprint. Ever since I updated, I can still connect to LTE, but as soon as I'm on LTE, I am not able to use any data at all. The signal icon is blue like it is connected all the way and in use, but I can't do anything data related until I fall back to 3G. I reflashed 4.3 from the sprint dev forum on here. Its the stock 4.3. I wiped everything before I flashed it. Any ideas?
Thanks in advance.

Any ROM I use, data roaming does not connect. I went back to completely stock ROM and it works fine. Yes I have data roaming enabled on each ROM. Any ideas?
Assuming your going from stock 4.0/4.1 to a newer 4.2 image, did you flash all of the most recent radio images when flashing the rom? I noticed a drop in the reliability of my signal when I went to 4.2 until the latest Toro+ radios got posted a few days back, now everything is back to normal. Also, did you update your PRL? Not sure if it would make a huge difference, but I always make a habit of updating the PRL & Profile whenever I flash a newer android version or when a new rom seems to be causing roaming signal issues - seems to help most of the time.

I've had this issue on every single radio that came out. I'm on the latest GH. PRL is up to date.
No one has this same issue?
I went out of town and lost phone and mms . I still had internet access. Keep turning off and on and turning data a
Off and on. It did pick up service eventually. Is this a radio issue?

I can't seem to fix my signal after flashing a ROM anymore. only get 1x which is only better than no signal at all. At one time in the earlier releases of M.O.A.R I was getting LTE and 3G with no problems then later releases I've lost both. I unrooted and went back to stock and my 3G was back and rooted again, went back to MOAR and still no 3G. So now I'm on beenstalk and still cant get a signal. I love both of these ROMS hands down and would like to fix this issue without experimenting with every ROM in the forum. Has anyone else had this issue? I've resetted radios flashed different modems (except MK3) and I still end up with bad network. I need help
Open the dialpad, and then ##72786# . The Device will reboot a few times. Just let it do it's thing. It will go through the Handsfree Activation Process. This will reset your Data.
Yeah.... So I updated my ROM to the newest carbonROM nightly.... Suddenly I couldn't pick up lte, only 3g. So... I reverted to a previous backup. Didn't fix it. So... I flashed to a touchwiz based ROM, updated prl and profile. It said I had 4g but I'm pretty sure touchwiz just lies and says it has 4g. So I flashed back to the version of carbonrom I had been using previously without issue, still only 3g. Flashed mk3 modem, booted back up, no connection at all. Flashed back to md4. Still no connection. So I restored to a backup of vanir ROM. No dice. Still no connection at all. Flashed back to touchwiz, no connection. So I updated profile and prl. Nothing. Flashed mk3, nothing. Used the code to factory reset and reprovision the phone. Got data back. Again, touchwiz lies about 4g. So I restored my phone to an old carbonrom that I had had no issues with, and I'm only getting 3g. Seriously, what happened and how do I fix it?

Of course, after I take the time to write this, I get a text saying my provisioning was successful and it starts working
Was on nf1 and experienced lte data dropping out of nowhere. It happened once everyday, sometimes more than that. After a toggling data on and off it would work again.
I updated to NF4 and problems have continued. Anybody else having this issue?

No.
I do see that when the phone transitions between 4G and LTE or vice versa, I loose data for a few seconds. But that is rare.
I've been experiencing this forever. Seems like no one else is though. Only thing I can do is toggle airplane mode on and off and deal with it...

I ues aosp. It goes from lte to h+ something. Is that considered data dropping?

If you can still use data than no. Data dropping is when it completely cuts out.
I have an N900t on T-Mobile but was experiencing the same random signal loss/no data issue as the OP after the 4.4.2 OTA and updating the baseband to NF4. Afterwords I rooted using the (CF-Auto-Root) for NF4 method and installed the Effortless 4.4.2 stock based ROM. Had the same signal issues so I went back to stock NF4. I immediately got notification for update to baseband NF9. Did the update and so far so good on the sudden random dropped signal issues. Now trying to figure out if the Rooting NF4 (CF-Auto-Root) still applys to rooting the phone after the NF9 update.

Would you mind posting a screenshot of your "About Device" page showing the baseband and build? TIA

Yes, I'm having the same issue. Usually turning on airplane mode then turning it back off fixes it. I updated to nf4 a few days ago and still have the issue. Stock t-mobile rom, not rooted, service with t-mobile.

I'm nf4 and updating stopped the data drops on lte but on switching to 4g data takes about a minute to respond, on NB4 lte would become unresponsive. ..so that seems fixed for me on nf4.......i did a full wipe including internal sdcard and everything has been working fine except the handoff to 4g. Don't know if it helped but i took out sim during the whole process. Ran stock nf4 firmware with pc odin, then rooted and replaced custom recovery then booted to recovery wiped everything except External Sd then rebooted the recovery back into the recovery then flashed the rom I'm currently running.
In your case since your mostly stock I'd get the pc odin tar, remove the sim, then run odin and select the "update bootloader" switch (or something like that) and run it and then boot into the rom (still without sim) setup phone then power down and pop sim in and try the features again that you've had problems with.
(^^^just a suggestion, maybe someone else has a fix)
Also backup your internal sdcard prior just to be safe.
i am with ringplus. today, suddenly i lost my cell network. can not make calls, other phones on ringplus seems to be ok.
so, now i need to flash a TW rom to update prl and profile. I saw the SwamMonster v3.0. downloading now. i suppose its KK. anyone know what must i do to downgrade from 5.1.1 to 4.4? thanks.
I'm on boost and lost all cell service when I flashed a backup I had. I just flashed the latest stock rooted we have and it's back up just fine.
it seems like a ringplus issue. been fix for a days. hope it will stick. thanks all
