Lately, my phone seems to have a real problem going from Wifi to mobile data. I know the location I'm in gets a GOOD 4G signal, because if I approach the building before it can see the wifi, it will be on 4G and working just fine. After going inside, connecting to wifi and leaving, it can take over 15 minutes sometimes before I get any mobile data connection.
I've tested 4G in the building by disabling wifi before arriving and the entire time it stayed on 4G and worked as expected. Any ideas what is going on or could fix this?
Software version: 3.16.651.3 710RD
Android 4.1.1
PRI Version 2.97_003
PRL Version 25015
I do have root, but I'm running stock. (Strange, I know. Few roms I tried give me no touchpanel and I've not set aside the time to figure it out fully. Also, 4.2 seems to have bluetooth issues?)

I'm having the strangest problem, my browser is not cooperating with 4G. Especially with Google, the progress bar just sits there nearly indefinitely. It can load full sites, such as topgear.com, but it hangs at the end before the bar is full.
I can toggle down to 3G and it works fine. I'm currently running the OTA MR2 radio. This started, however, some time after I flash Chingy's latest leak. I've flash radios back and forth a couple of times, cleared cache and dalvik, clear Internet application data, I've even done a complete wipe (wiped everything twice) and re-flashed without restoring anything what so ever. Nothing works other than toggling down to 3G.
That being said, it's not a connection issue. I can tether and it runs great, speed tests ran from the phone have good results and most application that use data are fine. I'm baffled.
Any suggestion? Any one ran into something like this?
Thanks.
I had the same thing after flashing the new leak. Don't have a clue if its related or not, but my PRL changed after doing so. It went from 15011 to 15027. Afterwards, LTE connectivity was intermittent at best. Even when I set my radio to LTE only. It would stay on 4g for a bit, then go to 1x for no reason. After a couple of days now it has settled down. I did not change from MR2 leak.

My PRL is still 15011 and I have no issues with LTE connectivity. It doesn't drop LTE, tether works great and most applications that use data work fine. My issue is with the browser loading pages. I can refresh the Google home page and it will sit there for minutes without making any progress. Then I can imediately run a speed test and get 20Mbps, all while tethering without a hiccup. This is driving me nuts, I ran into a couple people over at rootzwiki who are having the same problem. Oddly enough we're all in Texas. *scratches head*
Ok so here is my issue I've tried two different rom Clean Rom 4.2 ICS and Bafm 2.0 ICS.when i do wifi tether its works fine for a moment then all of a sudden it stop transmitting data in 4g then goes to 3g or no data and when i stop the wifi it stays in 3g or no data i have to reboot the phone to get 4g or 3g back I would like some help with this if any can.

VZW is on to you.
How long does it take before 4G cuts out? I just tried it on mine and so far its been stable for a few minutes of tethering to my tablet and streaming some Netflix.

I have not experimented with any ICS roms other than Nils ICS Business. Under settings make sure you set it to Nexus (CDMA/LTE) with routhing fix on. After that it should work smooth. If not, there are only two other possibilites one being your ROM or two being your on the edge of 4G coverage and your phone's signal is drawing so much trying to transfer data that it drops from 4g into 3g. Ive had similar instences where this has happened and I end up turning WIFI off and then Mobile Network Off, followed by turning them both back on to regain 4G.
Also you can try updating su binaries, sometimes that helps problems with tether.
So, I S-offed my phone a while ago. I finally convinced my wife she should let me S-off her phone a day ago.
After S-off, I flashed the newest ICS leak (2x to make sure the RUU ran properly) and then flashed the stock deodexed rom that Scott posted.
That way she can have root, and I can remove some of the bloat apps she doesn't want via titanium and call it a day.
However, her phone is having some serious issues with 3g constantly toggling on and off while on wifi. (We don't have 4g in our area). I thought it was an issue with the kernel not flashing properly, so I wiped, and flashed it seperately. Still no change.
I reran the RUU 2x, and reflashed the stock leaked deodexed rom from Scott.
Still not changing the results. Her phone is running at least 10 degrees hotter from the constant radio toggling. Phone is reporting the same kernel and radios that I am.
Further investigation reveals that my phone is running on EVDO Rev.a, and her's is running on eHRPD. Running speedtests on the phones shows her getting 2-3x the data speeds of my phone while sitting in the exact same spot in the house.
So... any idea what's going on here? Technically eHRPD is better for data speeds as I understand it. However, if her phone is running at 104F and it's killing her battery it's not better.
For reference, my phone is also S-off, with the newest radios and kernels. I am running Rez Rom 2.1 which is a Sense 4.0 rom vs her stock deodex. As far as I can tell, mine being Sense 4.0 shouldn't be influencing the data connection like that.
Any thoughts would be really appreciated.
This is interesting,
where are you seeing which network you are connected to?
System settings> About Phone> Network.
It's listed there under Mobile network type.
Update:
I flashed her phone to the same Rez Rom s4 2.1 my phone is on, and it seems to have stopped the toggling issue.
She's still on eHRDP vs. my EVDO rev. a and the speed difference is huge.
Any ideas how to switch over to eHRDP?
If you have the 3G icon on both phones, then both phones are connected via EVDO Rev. A.
eHRPD is essentially an authentication protocol that allows switching to LTE when it is available.
Even when toggling LTE off in the network settings, the phone still connects via eHRPD. On the Droid Charge with a ROM with TSM parts, one can manually change the network selection. If you want voice, you need either 1X only mode or eHRPD 1X mode. If you only care about data, then there is an EVDO only mode. There is also the ability to force EVDO Rev 0 and still have 1X, but Rev 0 is even slower than Rev. A.
I don't think there is an easy way to change these settings on the Rezound (I'd like to know if there is.)
Generally, eHRPD is known for having data drops because of some network authentication issue. I have tried EVDO Rev A only mode and had less issues, but I have not tested this in a 4G area. Verizon may have fixed the eHRPD issues or they may not have.
Concerning your problem, I don't really have a guess what the problem could be. I can confirm that I have the CDMA selection in the network settings and that Network Speed confirms my network as eHRPD.
Procede with caution, since I am a Rezound noob: I would suggest running the RUU again along with the radios to see if it was a wonky radio flash. I can tell you that for some darn reason, I seemingly had to flash the radios on the Droid Charge several times in order fix some radio problems I had...

Beat me to your post. Are you in a 4G area? What speeds are you getting? I've never seen a phone get stuck on EVDO Rev A only mode with 1X still working. Try toggling 4G on and off and rebooting.
We don't live in a 4g area.
Update again:
My phone has switched over to eHRPD and things seemed to have calmed down. I did reboot it previously, and togggle airplane mode a few times and it didnt care about changing over from evdo.
I guess the weird toggling issue on her phone brought to light another issue that might be unrelated?
Thanks for the insight xdadevnube
2 EVO LTEs, both running latest firmware package with updated radios. One running stock rooted, the other Mean Bean. Last night at a basketball game, my phone (Mean Bean) never could keep a connection, it would drop data, and go to 1x, then drop 1x over and over and I couldn't update my status let alone upload photos My wife's (stock rooted) had no issues. Held 3G all night and she could upload Facebook photos of the game.
Seriously what makes this happen? Can a ROM have any effect on the 3G connection? I already checked the build.prop for Mean Bean to make sure it wasn't including any of that 3G Turbocharger RIL changes which I know can cause connection problems in certain situations...
Actually, not the latest firmware, I didn't know there was a 3.16. They are both running 3.15 with the 3.15 radio/PRI/etc...
Have you tried updating your profile & Prl?? Also have you tried a data reset ??

I'm having this exact same issue, it seems to persist on any Sense or AOSP rom. Whats the deal? Do I need to update my radios or something? I'm on PRL 25009 and baseband 1.12.11.1119 currently running CM 10.1, but I've had the same problems no matter what ROM I'm on.

Yes i had the same problem with data connection and battery drain due to the crappy radio (1.12.11.1119).so I flashed a different radio and that fixed my problems.update your full firmware to the 3.16 base that includes the latest radio img.,but doesn't include the tp.img to the latest and then update your profile and prl.
You can get the full firmware here =

It seems all lte devices have this issue. For some reason lte devices constantly drop down to 1xrtt. My note 2 and Evo lte constantly do it while my gs2 and evo 3d hold a steady evdo connection. I also heard some ppl with the LGOG have the same issue. I toggle airplane mode on and off to get ehrp back on. It's a bit annoying but I'm betting it has to do with the device scanning for lte and making it drop to 2g.

I am not sure when/where/why, but since I switched to the roms based off the 3.17 OTA update, I have had no 1x Data on my EVO LTE. 3G/4G work fine, the HD Voice is great, but when I am outside of 3G range, I have no data connection whatsoever and the phone gives me data call failures almost nonstop.
I have tried flashing the latest radios, bootloader, etc but so far nothing has gotten my 1x data back. (though it is a bit tough to test. Is there a way to force 1X only on Sprint?)
Right now I am on the Sense 5 Y8 rom and while it is fantastic, I still want to get 1X back so I was wondering if formatting everything in Recovery, then running the latest RUU from HTC's site to hopefully restore/update everything in the phone would work.
That is the closest to force restoring the phone to default correct? Has anyone else had an issue similar to this?
