Please help, EVO 4G connectivity goes in and out after rooting

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!

How is your 3G connection since latest radio install?

This isn't related to any particular ROM as I have tasted this with various sense and none sense ROMS... Has anyone since using the latest radio had issues with connecting to 3G or having very strange fluctuations, where the signal might go dead completely then back up to full?
I seem to be experiencing this with 32.43.00.32U_5.09.00.20

nope seems fine with mine. OD rom in Australia

The mentioned Radio is really poor in 3G Network. Especially change between 3G and EDGE. When I disconnect from Wifi it too often doesnt connect to the GSM or 3G again - the bars are there, you can phone but cant use data connection.
I hope there'll be a updated radio soon!
Im not happy with 5.09.00.20.

Hi,
I'm also experiencing a poor 3G connection with this radio.
I'm not happy with that.
Vodafone Spain, also same while itinerance in Portugal, USA.
Best

this radio has been absolutely fine for me.

having poor reception at singapore here too...
should i downgrade the radio?

Working best for me. From Malaysia.

Not working at all well for me. All was working great until I flashed to this radio. I'm now experiencing complete signal drops at least once an hour, have to toggle airplane mode to re-enable.
I tried rolling back to each other radio bar the first 3 or 4 with the same result.
Could it be something else or am I missing something when rolling back the radio?

It works fine for me as long as I stay in Copenhagen, but I've experienced losing signal altogether when travelling, this didn't happen before, so I think it's because of the radio.

I have a weird issue where I never seem to be able to access the Internet in any way until the connection icon changes from "3G" to "H". Is this normal? I haven't noticed this on the stock radio but then I didn't keep it that long...

Still having this "issue". Anyone else?

New version is working really better here.

Where could one get that version? And is it supposed to work on any ROM without breaking it?

I have the 32.44.00.32U_5.09.05.30_2 radio and am on Telus.
I have the same issue as you. When the icon shows 3G my internet doesnt work at all but as soon as it changed to H (bang) full speed internet..
It did it for me on the 32.43 radio but not on stock. Anyone know what the stock Telus Radio is?

Guys you do know on telus we dont have a 3G network its strictly "H" that would be why your internet does not work. I would like to know how you managed to get stuck in 3G as i never have.

I have no idea - i just updated radio and rom to 2.2 Official (but rooted) - i entered the apn settings from the telus website.
When on internet things will be fine, internet loading (H in task bar) and then suddenly it will turn to the 3G icon and internet will freeze until the H icon comes back. Strange...

When i go into the settings and check my phone model it says its a HTC Desire A8181 - i checked the internet and this model is 3G Dual-Band 900/2100MHz.
Before i flashed a 2.2 rom my model showed as HTC Desire 8182, which is 850/1900 3G.
Could this be why its getting stuck on 3G instead of H?

My model also displays HTC Desire A8181 and I'm running a 2.2 ROM.
I don't remember what it said before on the Telus stock rom, but I could try flashing it back to see, since I have it in backup.

If you could try flashing it back that would be great - i think i have my Nandroid backup but its on my works computer...

Not connecting to 3G EVDO, only 1xRTT

Hi, I was hoping someone here may be able to help me out with this problem. Last week I had a weird issue where my GPS signal stopped working, text messages and phone calls weren't coming into the phone. I've since been able to correct that issue with flashing to a clean Sense based ROM, and updating the profile and PRL, but now I can't seem to pickup 3G EVDO signal, only 2G 1xRTT..
My phone is(was) rooted and flashed with Calkulin's EViO 2 v1.77, most current radios. I thought maybe something got messed up, and since 1.8 was out, I flashed to that. Same issue, updated the radio from his package, same thing. Then I thought, ok, maybe something with this rom is messed up(unlikely, but I was grasping at straws at this point), so I flashed to a different rom, think it was sprint lovers.. same thing. Flashed to CM7, same. Unrooted and flashed back to stock, took it into Sprint, which they did a hard reset and told me since it shows the 3G icon in the top bar, it is on 3G and working fine. This is ofcourse bull**** since the Evo shows that 3G icon even if its on 1xRTT signal..Sprint tossing out wrong info, shocking I know. I've used Antennas and OpenSignal apps to show that it is indeed connecting to the 1xRTT signal. Downloading anything on the phone is ofcourse slow too, I've had google maps updating now for about 15 minutes, and it is 5.86MB.
Would anybody have some suggestions of what I can try to get the 3G radio working again?

Anybody have a suggestion of what I could try here? I've changed my PRL to the Verizon one, which gives the same results. Still having the same problem.

ya its calkulin's 1.8. the new extended mobile data menu hack has a messed up default that sets it to evdo only by default, messing up everything else. switching roms doenst help. go back to calk's 1.8 and type in the dialer ##3282# select view only and make sure mode of operation is on automatic.

[Q] Voice and Data

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!

EVO 4G fully flashed to metropcs, WEAK wifi signal

Hello,
I have a EVO 4G fully flashed to MetroPCS (talk,txt,mms,web) etc all working properly. But I have one issue: I get barely any reception/bars in my house so the DATA is pretty useless. So I want to use Wifi but Im getting barely any signal from the wifi router that's placed 2 rooms down the hall. I get almost full bars and an excellent signal on my Laptop and my other EVO 4g that's on Sprint.
I looked searched online and found out I'll have to disable DATA so my wifi wont cap off at my data speed. After disabling DATA I still get very weak WiFi signal almost useless with frequent connection drops. I never had weak wifi signal prior to flash on the same phone when it wasnt activated with any service.
Phone is using MetroDroid v2.2 with android 2.2. I dont know why they didnt use metrodroid 3.0...
My question is what's causing weak wifi signal? Is there anything I can do to improve it? Also is there another rom besides the Metro droid that can be fully flashed to MetroPCS with improved wifi?

You can flash any rom you want with out losing metro settings the things the roms change don't affect the partition the settings are on just like radios don't change with a rom flash they are in a seperate partition from the actual files that create the UI and system partitions

The guy that flashed it at the metro place said the flash and all settings will be lost if I flash another ROM. I will have to pay again for the flash and the unlocking etc.

Dude lied to you, you know you coulda flashed it yourself for free right? Hey ill flash a recovery for you for $35 lol j/k the settings are set thru epst I believe in the nvram all that needs to be changed between roms sometimes is the apn settings for MMS and you can use GOSMS Pro and change those on aosp roms or a downgraded epst to change them on a sense rom, there are tons of tutorials on how to flash to metro boost and cricket all over the interwebz and you can find all the info to flash your phone in them

Well i tried to do it myself first following a tutorial on one of the threads here on XDA which also had metroDroid...but when in CDMA workshop my SPC code was showing up as all zeroes. Was also kind of busy so i decided to take it to metro.
Any thoughts on why the wifi signal is so low compared to before when it wasnt activated at all? And if its possible to flash any rom and not lose the flash and data stuff which Rom should i go for? and where exactly can i find instructions to re-do all the stuff?

I've never personally flashed a phone to another carrier but someone who has will stumble in here and help with settings for roms I'd go with the classic by tommytomatoe or mikg 3.0 if you want sense or decks gb rom if you want aosp wifi is probably low due to either a bad flash on your rom or a setting not configured right, before you had it flashed to metro it was probably on sense (I think metrodroid is aosp) and sense shows higher signal strength whereas aosp shows lower signal even tho it's identical the higher signal on sense can trick the connection to stay active even tho its really a weak signal but the speeds will be affected the only settings you will most likely ever screw up would be web and mms and those settings are easily found thru a quick Google search for "evo 4g metropcs web and mms settings"
We are legion, for we are many.

Well well I flashed the classic ROM yesterday and the ROM itself works perfectly fine but i was still having the same issue...so i decided to take the phone apart to mess around with the antenna(s)? I bent them up a little bit and put it back together which result in much better Wifi signal and much better reception and so far i haven't seen signal drop anywhere.
But since I flashed the ROM I still have the web and 3g settings but I messed up the MMS settings. Is there a MMS script i can install/flash for the classic ROM that can get the MMS to work? Or any other method that's not too complicated (I'm a noob). I have tried SMS pro and had no luck.
Will appreciate any thoughts on this. thanks.

Can someone please help?
