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.

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,

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.

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 was having issues with my 3G cutting out randomly. I would be in a known coverage area, and in the middle of a speed test, wifi tether, or any other app requiring internet, the 3G would just stop working. The 3G icon would blink as if it was trying to reconnect, but wouldn't. I would either have to restart the device or cycle the mobile internet on and off. I would also get error code 67 and 104 randomly as well. Today, I updated my Radio to 2.15.00.05.02, but haven't really had the chance to see if it's functioning correctly. Any advice? I'm a bit of a noob, so keep it simple for me.
Sitting at home with the EVO on 3G and just got error 104 again. Running...
ANDROID 2.2
PRI 1.90_003
PRL 60672
Just updated to ANDROID 2.3 and the latest RADIO combo pack and I'm still having the issue. During SpeedTest, the 3G stops responding randomly. Sometimes it picks back up again, but most of the time, it will stop responding altogether. Settings issue? Any help would be great.
A Tower is down on Sprint (sub-Boost Mobile).
That is what's causing your in and out fades.
Should be updated by end of the week.
Boost Mobile (EVO)
Android 2.2
2.15.00.11.19 (downgraded as I thought it was radio, but will be upgradeing back to Radio 2.15.00.05.02 after Tower is repaired)
Software 3.70.651.1
PRL 61007
same problem here, but with good towers
hey guys I have the samsung epic with the same proble, it works fine and fast on 3g but sometimes it just stop working. the 3g arow keeps sending, and I get the same error codes, so, what can I do to fix this? ah my epic is on boost mobile
So others are having this issue as well. Interesting....anyone got any ideas?

I have the same problem. It has nothing to do with the towers. I am running synergy RC2 and my 3g will drop. I have to then disable the 3g and reinable it for the 3g to work. This will last for 3 minutes to 5 hours. It's very annoying. I have come to the conclusion that it is either software related or the PRL.
Some PRL's have more problems than others. It seems that the boost PRL (I think it is 61007) will be running a speed test and cut out and I get an error saying there has been a network communication error. 60678 seems to work best for me although I have to keep resetting the 3g.
I have the same issue with the Speedtest.net app. It cuts out with a network error. Anyone else got any input???

i wish i had ur problem -.-, mines it i cant make calls or texts, says my account could not be validated, but my 3g works fine =[
Hey guys,
So I've noticed that I cannot do voice and data simultaneously (call someone and surf the web at the same time). I know its supposed to be possible under 3G and HSDPA for GSM networks. I am in a perfectly good HSDPA region (3G too for that matter, but my phone shows the H icon).
The only reason I can think that it is not working is because I am currently using the Vision_Radio_12.52. 60.25_26.08.04.30 (from *LEAK* Vision_Gingerbread_S_TMOUS_2.13) radio which is not the newest one.
So will upgrading my radio solve the problem (I can do voice and data fine individually.)? Or is it just not possible for some reason with this phone?
You can but only with 4g, the h on stock means 4 or 3g
No same for me and I am on a different radio the one ending .12,data turns off when talking,as to the reason why, I dont know, I just know it does not work.

Ok, but like I said, I am seeing an H indicating that I should be on a HSDPA network (there is a seperate 3G icon when I am in 3G).
Regardless of 3G or 4G, I thought GSM can support voice + data over both 3G and 4G.
Bombadier is using the latest radio and is having the same problem so I wonder what is the reason behind this...
Radio and ROM specs in my signature, I have no problems talking and surfing while in H or 3G.

Quick question do you have mobile network data always on?
Whatever the default is, I never manually turn it off, but I do use juice defender and allow it to turn off mobile data only when my screen is off.
Should of said on the phone running Unity, as I have it set from settings - wireless and network - mobile networks - not always on, will change it to always on and see if the connection stays on while talking.
Edit Just tested and the data connection stays on while I am on the phone,the OP should try mobile networks always on then.
My mobile network is already set to Always On.
When I get back home, I will update my ROM to the latest InserCoin v1.61 and the newest radio and report back. Hopefully, that will fix my problems.
Also, once I flash the newest radio, will I have to flash RIL too?
Just remember, newest radio doesn't always mean the best radio. I'm using an old one that after trying 5 different radios turned out to be the best.
Not sure about RIL's on sense though...
Seems to be all quiet about the need to match the rils,I used to, but had a few bad experiences matching the rils on the new unity releases 2.35+ so have stopped doing it,certainly with AOSP based roms it is not recommended to match,hope you get your problem sorted.
P.S. As the other chap said,the newest radio does not always mean the best radio,a bit of experimentation is required,also be sure to wipe the EFS data when changing radios.Link to a flashable zip can be found in the radio thread.
Updating to the newest ROM, kernel, and radio solved the problem. Thanks everyone for the help!

Pleased to hear you are all good
I have a problem that I cannot find a fix for.
I have used the 4g hotspot hack that is implemented in Calkulin's 2.7 rom and WiFi tether; neither of them work.
WiFi tether will start with errors regardless of whats used. So thats it for that one..
4g Hotspot hack will allow connection in 3g and 4g, but the 4g is roughly 10kbps down. 3g is faster.
I used it on my tablet which is the Lenovo K1 and thats where the speed test is run.
Next I tried it for my laptop. It connected with limited connectivity and after 5 minutes it got a connection. I went to speedtest and it lost connection. This was with 4g when I have full 4g bars. Same issue with 3G anyway so it wont make a difference.
Speed test app on my phone gets about 10-12mbit down with 4g. Im really lost as to why its doing this.
went from EK02 to EL13 to EL26.. no luck.
Same Here
I am actually having the same problem. I've been looking through the treads to see if anyone has posted a solution, but you're actually the first person I've found that has mentioned it. Either with 4G or 3G on, I', getting less than .45 Mbps on devices connected to my Sprint Hotspot. Meanwhile if I run a speed test on my phone, my 4G connection is anywhere from 3 to 5 Mbps. Very frustrating.
OP which versions of wifi tether have you attempted?
Here's what i would do. I would update to Calk's 2.9.1 Rom, and flash a new modem (el29 is my current fave). Update PRL and Profile, reboot for good measure. Use the stock Sprint Hotspot app (set security if you choose) and it should work. My fiance's phone is running all that perfectly.
Solution : I am a heavy data user and I use the Sprint hotspot with 4G and at first I was having problems then I found a way to make it work. first you MUST keep 4G on and not let it idle at all . Second when you enable the hot spot let it settle for about 5 minutes to allow the hotspot to set the right channel for WiMAX if not it will not connect and also will give you low speeds. third keep the charger connected.

For the past week and a half, I've had internet issues when I'm on 3g. It works fine on wifi. I've switched between ROMs, kernels, modems, etc. I'm currently on Goodness with the MA6 firmware modem AIO and the anthrax kernel. I've tried updating the profile & prl. I have between 2-4 bars of 3g and yet it still gives me the webpage not available sign. I tried clearing the cache/ fixing the permissions. But the internet simply won't work. I'm in Maryland, between Baltimore and Frederick. What could the problem be? Maybe the phone itself is defective or Sprint's network died in my area?
I'd see if they're doing work i that area. I know in areas of Baltimore 4G is there, I believe. You could try using build prop tweaks ect for signal if you wanted.

Misery loves company.
The 2nd post is a thread I started regarding the same problem. The first post is to a thread I thought could help me. I tried some things mentioned in there but none of them worked. Then someone posted in the thread who is having the same problem.
Here's what I've been running into and what I tried. I am on FreeGS3, Anthrax kernel, and recently updated to MA6 when I started having problems. I use a battery saver so my internet connection turns off when my screen is off. I started noticing a week or so ago that when I woke up my phone, the 3g icon would appear but only the up arrow flashed. The download arrow wasn't doing anything. I would toggle it off and on and eventually get it to work. I'm in the Raleigh-Durham area and we are just starting to get LTE. My 4G works whenever I go through 4G areas and my wifi works. I have restored a working backup, wiped my phone, flashed back to stock unrooted, called Sprint (they refreshed my signal and had me do an OTA activation), manually changed my PRL, upgraded to MA6, updated profile (when I could get it work).........and I think that about sums it up. The one thing I've noticed is my phone works flawlessly when the network mode is set to CDMA. At this point I'm clueless. I really don't think it's a phone issue because 3g works on CDMA. It's like when the phone is set to CDMA/LTE and it doesn't have an LTE signal, it doesn't know what to do. That up arrow flashes in such a rhythm that it's like the code is stuck in a loop.
