my 4g and 3g signals keep alternating..... seems like clockwork every 10 or so seconds... and im getting 2 bars of 4g.. :/
anyone else having this issue? i've tried both radio versions.
Moved as not Android Dev.
If you move to an area where your phone loses 4g then it takes a second to switch back to 3g. If your phone keeps finding and then losing the 4g signal it could do this.
It could also be exclusive to the custom ROM you are running?.. If you are..
This is when I stay still... im in philadelphia where they have 4g... right now I'm rooted.. running rooted stock Rom. No 4g data transmission at all but I believe a lot of people are having this problem with the Rom? I believe I was having a problem before I actually rooted though.. anyone else?
Not till I tried to run Fresh rom then I tried damages rom same outcome my 3g and 4g keep altering went back to my rooted stock and its good again. When I tried to flash the 4g fix it would stay in 3g and the 4g would be stuck in turning on mode this was done while on the fresh rom
I had the exact same problem. It has nothing to do with signal strength.
For some reason, the Wimax is set to disconnect after 10 seconds if idle time.
Idle time is defined by the number of seconds no traffic is passing to or from the internet.
When it disconnects, wimax will rescan and reconnect to the 4G network.
I found a fix for this, you will need your MSL code though to fix this so call Sprint and ask for it.
##DATA#
EDIT mode
Put in your MSL code.
Wimax
Change "Wimax_idle_sleep" from 10 to 300 seconds.
Click menu > commit changes.
Your phone will reboot and problem solved.

thanks for the post this fixed the problem for me! also i used this tut to get my msl code: http://forum.xda-developers.com/showthread.php?t=697487
now the battery life is a lot better as well thanks again
This is great. I was trying to make these modifications directly in the [mac addy].tree.xml file and they wouldn't persist. A reboot and the values I modified were reverted to their original state. I didn't realize they had to be modified here.

4G in New Jersey
I get 4G in my town, bound brook, NJ. Its almost as fast as wifi.
This problem was pissing me off to no end. This procedure fixed it perfectly! removing tree.xml first did not fix it, although some people have had that help them instead. Nothing is ever consistent but in the end, something usually works.
Hi guys,
Please help me out here:
After I rooted and unlocked NAND on my EVO by following the guides on this forum (part 1 and part 2), my 4g connectivity is totally unreliable.
The connection switches between 4g and 3g a couple of times a minute. Sometimes the EVO will have a full 4g signal and an ip address (according to the settings app), but when I open the browser it says that there is no network connection. Switching the phone to 3g fixes the connectivity issue.
I live on the 14th floor of a high-rise and had full 4g signal before rooting. I have tried the stock ROM as well as the Bugless Beast ROM and I get the same results.
Does rooting and unlocking NAND somehow mess with the 4g radio in the EVO, anyone have this issue in the past? Please help, I don't want to take this thing back to Sprint and go for the iPhone
Have you updated the radio? Go to settings and see if you baseband is 1.39.00.05.31
4G Radio
What is your current baseband at?
you should be at 1.39.00.05.31 or higher. If you look for the Fresh .2 Rom, they have the Radio zip. reboot into recovery and flash with the new Zip it will update your Baseband radio will be updated.
I had issues with 4G connectivity I updated my radio and I am all set.
-Joshonekenobi
Yes, I just updated to the latest baseband and it's still doing the same thing.
The phone shows full signal on 4g and all of the sudden switches to 3g and back to 4g again. This occurs several times a minute.
Is there some way I can flash it back to completely stock ROM?
Thanks,
Rayden1000
i'm rooted via unrevoked and my 4g is spotty. rooted or not. for me I think its 4g not set up yet. It is a work in progress. I'm in St. Louis. Speeds suck as well.
Avg. 1.2 download 4g
Avg. 0.5 download 3g
I am in Baltimore, the first 4G market. I really don't think it has to do with coverage....before rooting (and even after rooting, when on 4G), I get about 3.6 down and 1 up (upload is capped at 1 by Sprint).
I also live in a high rise that's half a mile from Clearwire's 4G tower........my issue is that after rooting, the EVO is not locking to 4g, it keeps switching back and forth between 3g and 4g.

Same issue here... Try this: go to settings and disable mobile networks (i.e. turn 3G off). When I do this, speed test works fine, but as soon as I try to do something real it disconnects and says there is no connection, even if it had a strong signal... not terribly useful!

L_Mo,
Were you having this issue before rooting (I am just assuming that you did root)? I swear that I did not have this issue before doing the full root and Nand unlock. When I just had Unrevoked root, I was using my Evo as my internet connection for my laptops for a full week with no issues and as a result I disconnected my Comcast cable internet.
I am just at a loss here, if I can't get this fixed, I will have to either flash the phone back to stock or take it back to Sprint for an exchange.
Rayden1000
I had the same problem after rooting. I am having better luck with Flipz stock rooted rom. I am using Flipz ota 1.32.651.6 rooted rom with the 1.39.00.05.31 radio. I wiped cache and delvic before flashing.
If this doesn't work for you you can get the stock RUU and reflash to unrooted stock.

Unrevoked is a ***** root and couldn't possibly mess with your 4G, sorry to say!
And, to the rest of you, rooting would not mess with your signal at all unless you dropped your phone or some ****. Installing the newest radio would be my only recommendation. Or you can unroot it and try to exchange it for a different EVO.

Thanks erikjonpeterson,
I am going to to download that ROM now.... I knew I wasn't crazy when I said that 4G worked fine before rooting. I am finding more and more info online about many people having the same issue

I had the same issue. Reflashed the RUU and still had connection problems (good 4g signal, but use the internet and it drops and switches to 3g). Didn't have problems with my 4g data card though.
edit: I actually thought I messed something up myself before I even rooted. I was in a bad area and kept roaming even though I could get a weak Sprint signal so I switched it to Sprint only and I think I mightve messed with some other settings under that mobile network tab. What are the default settings?
So basically, something in the full rooting process (not the unrevoked one), f's up the baseband or access to the baseband? I am not an electronic engineer, but it's obvious that doing the full root messes up 4G.
Any senior members in the know have a fix for this? I already exchanged my Evo once because of several stuck pixels, it would look suspicious if I went back to the store again...

Don't take what I said as a definite Evo or root problem. I'm curious as to if it's a 4g here in Philly problem. When I first bought the 4g card it was great, but wasn't using it so I returned it. Bought it again 4 months later and I returned that one because the 4g was terrible. I'm thinking 4g where I'm at sucks and is getting worse with more and more people jumping on it. I was a 3g early adopter so I'm not worried yet.
edit: I'm gonna go down to an area that's known to have a good 4g signal after work and sit around and do some "testing".
Which market are you in? Sprint has been doing a ton of testing in markets that aren't officially live yet.
I don't think it has anything to do with the ROM.
If when you are connected to 4G you can access the internet, only suddenly 4G it drops for no reason and switch to 3G and then reconnects to 4G and goes on and on, below is the solution. if when you are connected to 4G you can not access the internet at all, the below wont fix it for you and it is probably a problem with your rom.
You will need your msl code to fix this, loop up in the forums to to obtain your msl code from Sprint:
hit ##DATA# > Edit mode.
Put in your msl code
Chose WIMAX
Scroll down to Wimax_Idle_Sleep
Change the value from 10 to 300.
Click menu, commit changes and restart the phone.
This fixed it for me and i never drop 4g (when in good coverage) again.
Basically Sprint has some STUPID setting that tells 4g to go into "sleep mode" of no data is passed on the 4g connection after 10 seconds which is essentially disconnecting 4g.
The problem is it goes into sleep mode (disconnecting), but then rescans and look for a 4G signal > reconnects to 4g and if no data will be passed in 10sec it will do the same again in an endless loop.
10sec to put a connection into sleep mode is really low so change it to 300sec.
The odd thing is that this is only happening in certain locations and with certain towers.
I tried to call Sprint and explain about this issue but my attempts fell on death ears.
Go ahead and try the above. if it helps you please someone make this a sticky as you are not the first i see having the issue.

I am in baltimore, the first 4G market.
I have to tend to agree that something in "Part 2" is messing up something with 4G. I've done Part 1 and successfully "upped" the radio with no 4G loss. Living in $G Vegas, I would get solid 2 bars inside my office. Once I did Part 2 and redid the phone, I would get "jumping" from 3G to 4G...
I still have to wonder, when flashing the new radio, why (after Part 2) it gets "stuck" in formatting cache and you get no "confirmation" of an upgrade. I am an AnooBroid...but this just doesn't seem right to me.
(Edited) - This post is now obsolete... Teaches me to refresh the page on the Evo before posting!
I know there are a lot of posts about internet connection problems, but I couldn't find anything exactly like my issue.
If I only have 3g on, my Evo will connect and stay connected for a few minutes, then it will disconnect for about 20 seconds, and reconnect agaoin for another few minutes... and the cycle continues.
If I turn 4g on and 3g off, the same thing happens with the 4g.
If I have 3g and 4g on, the same things happens except sometimes 3g will be the one to connect and sometimes 4g.
Wifi works great.
My Evo is brand new and recently rooted, running Myn's Rom RLS4.
anyone had similar situation or resolutions?
THnkas!
there are only pockets of 4G so far. dont expect there to be 4G around like 3G is. as it is, 3G still isnt dat big/nation wide, but 4G is like rare. its like a needle in a haystack. the needle is 4G surrounded by the Hay/3G
Thanks,
the thing though is that my wife's unrooted Evo always maintains a strong 4g connection.
It wouldn't bother me too much the same thing happens when I use 3g. it reconnects every 5 minutes or so. Maybe rooting it caused damage?
Could flashing a different radio or wimax help?

You'll need your msl number to do this. SImply download msl reader from the market.
Can you change any of the other settings that would make it work better?
Scan attempt
Scan retry
Thanks for this info, I gave it a try but I still cannot connect without doing a profile update and or PRL update.

I flashed the phone over to cricket but the 3g won't stay on, only way to get it to turn on is to switch from CDMA to LTE/CDMA and vice versa and then turning the mobile data off and on. But if you dont use the Data, it turns itself off again. Anybody know how to fix this?

I'm having a similar issue with my Lg Optimus G LS 970 (Sprint) Flashed to Cricket. 3G Does not automatically come on and off. What I have to do is turn off and on the wi-fi multiple times in a row. then the 3G pops on. My data is very slow under 50K down and the 3g times out within 3 to 4 minutes. I tried at different locations around my city. I feel like i'm so close like one setting off.
I have tried re flashing the internet settings with multiple programs, tried simple and mobile ip, I almost think its a setting in the phone. What could be causing the phone not to automatically connect to 3g mobile data? Also why when it does connect the speeds are slow and the connection times out so fast?
This phone is awesome but not having reliable data out and about is killing me.
Oh more thing is it possible to configure the LTE radio on the phone now for when cricket brings LTE to the Portland Market?
Any body have any ideas?
Correction Turn on and off "data" multiple times to start the 3G data.
Simply flash with wireless workshop

Could you point me in the direction of how you flashed your optimus g? Ive flashed a lot of phones but never an lg
I have the sprint lg optimus ls970 & it is current still turned on through sprint. We tried to take it to cricket to flash it over but the rep said the es something was locked...we are tired of sprint and would love to flash ot over to cricket. What are we doing wrong??
Hello. I have the exact same problem you have when I flash mylg ls980 to PagePlus. Did you ever fix this problem? I flash 3G to all phones I do for pageplus. But when I flash my lg ls980 I get an error MIP: 67. I used the modified nv items posted by a user in another forum so the HDR USER/PASSWORD stick. And the settings in DFS all flash correctly. I tried installing the LG Provisioning APK but it never opens for me and force closes. So I'm thinking this problem is with the phone itself. In the settings of the phone. Because what will happen the 3G Symbol pops up. Then when I look in the settings- status, I will have 1x then EVDO. Then when the EVDO connects, the 3G data disconnects. So I'm very sure its a setting in the phone that I'm not aware of. Because the flash works fine. All my HDR/HA/AAA passwords are right. The DFS flash goes through smoothly. So, I'm not sure you know.... =( Look forward to your reply.
where is this modified nv item ?

Ok have had this problem for a while now feel like i should try to address it now.
my s3 is stuck on 2g (edge) the frequencies for 3g and 4g ( technically 3.5g or H+)are all supported by my carrier (jamaica - Digicel) i payed someone to fix it a while back and it worked and now it has stoped working again.
when i try to force 4g ( via *#*#4636#*#) i get it for a couple seconds and then signal drops.
also from the 4g stoped working i have noticed my calls dropping more frequently even when data is turned off.
any advice leading to a fix would be greatly appreciated
