I seem to have signal issues on both ROM's. I'll give you guys a little background information.
I've used Fresh and Myn ROM's and always get perfect 3G coverage in my house and around town. Everytime I flash an AOSP rom I can't seem to connect to anything but 1X (if I'm lucky). When I was using the 2 previously mentioned Sense ROM's I'd have no issues with data. For the record I don't do a restore of my system data or apps when I flash because I prefer to download everything again to prevent FC's and other issues.
I've done a nandroid restore and updated PRL and Profile in a Sense ROM (2X) and then restored my AOSP ROM (ultimate droid) and that doesn't fix signal issues. My girlfriend has an Evo and she gets perfect signal on 3G (4G as well but she has it off) so it's not network related.
I downloaded the latest radio and pri from the development thread and flashed them in recovery. That didn't do anything at all and may have been a waste of time.
I then did these steps:
Dialed *#*#463+#*#*
Clicked on Phone Info
Turned off Radio (waited 1 min)
Turned radio back on
Ran ping test (failed because of no data signal). I can make/receive calls but nothing data related.
Is anyone having this issue? This has prevented me from fully enjoying AOSP ROM's and I don't know what the issue is. I'm using the latest PRL but could it be that my radio is broken? I would ready appreciate any help.
*** Update ***
I'm typing this thread on my phone and it's displaying 3G in full bars and then jumps to 1X full bars. It's kind of random but never steady. If anyone can please help me with this I'd appreciate it.
By the way I have an Airrave. Could that be the cause of my problems?

Same. i have this issue. although i dont get 1X. but i do however get spiking signal.
from what ive learned, the bars arent ur reception but how good ur connection is to the....satelites? aslong as u have 3G showing ur phone/internet SHOULD be working. although i would rather like to see all full bars where i normally would
i'm in a pretty high 4g signal area, but i love ultimate droid. i too have loopy 3g using cm6 or ultimate droid, would gladly give up my 4g to use either of these roms, but the 3g performance is way slower than on a sense rom. it's not just the bars, 3g on aosp is almost unusable, on sense roms, it works nicely
I solved my issue. The root of the problem is the Airave and how it connects with AOSP ROM's.
When I flash a Sense based ROM I don't have an issue with 3G and signal. I'm in a perfect 3G area by the way.
As soon as I disconnected the Airave last night my 3G signal came back with a vengeance. It hasn't left and is steady. I plugged in the Airave again and I saw my signal disappear and never come back. I could make/receive calls but no data access. I have the latest version of the Airave. Could someone (DEV) of an AOSP ROM investigate this issue. I knew it wasn't my phone because it would only happen in AOSP ROM's.

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.

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!
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.
my phone has been rooted for 1 year now and so far have had no problems what so ever, but just recently i flashed synergy rom and all hell broke loose. my phones 4g works fine and so does wifi but my 3G would not start, it would turn on for about 1 second then go straight to 1x.
things i have tried......
update my profile and prl...nothing
##data##, menu, restore....nothing
pulled the battery like about 155752 times....nothing
nandroid restore to a time where it was working...thing
flashed like 6 different roms and still nothing works.
flashed new radios and still a no go..
i tried to do the whole metro pcs flash but then changed my mind not to go to metro as its network is crapy. i went to qpst and cdma and reverted everything back to how it was, so i dont see why it would mess up my 3G
i have no idea what else to do, any help will be greatly appreciated.
If it is 1x, that shows the true data strength. You may have excellent connection, but poor data in that area, or the server is just temporarily overloaded. It'll correct itself. Previously, sense roms would always show 3G even if it was a 1x connection, but most developers put in that fix to show the true strength, like in aosp.
Thanks for the reply. the thing is that my wife has an evo as well and shes right next to me and gets perfect 3g data connections, and i was getting error 67 upon trying to update prl and profile. as soon as i did the reset on the ##data## it went away, and now it wont even connect to 1x at all...man its so frustrating, ive searched and search but nothing.
same thing has happened to me, tried chatting 3 times, and called tech support once, so far no data.
try this...i did not work for me at all but it might work for you...good luck buddy you'll need it lol...this crap is frustrating as hell.

ive had similar problems... just flashed a rom,, 3g working but hotspot isnt.... i need help too
Sense ROM's show 3G to identify a data connection, while the bars are actually displaying the voice connection. I believe aosp ROM's strickly display the data speed since voice reception is generally good. This may just be a placebo affect and you think you have poor 3G. I would suggest running a speed test on both ROM's (your current one and the one you found "good" data speeds on) to ensure that it's not the ROM itself.

I've got the same exact issue, but I've been on Synergy for a while now. As of last night though, no 3g... My France's unrooted EVO works just fine, and I've been in a few different areas, so I know it's not the tower. I've done the same things the OP has done and still nothing... Is it possible for the Rom to fry out the 3g??
Sent from my PC36100 using XDA App
Ok ive got mines working. However its still a little sketchy but atleast 3g doesnt go away. After going tjrough the steps in my last post, I did ##786# and resetted everything. Then reflashed my rom and walah!
This worked for me.
Step 1: Open dial pad , ##3282# enter
Step 2: Select "Edit Mode", then input your MSL number
Step 3: Select "Data Profile", then press menu button
Step 4: Select "Restore", then press ok. Should reboot on it's own. If not reboot.
You said you did something similar but figured it wouldn't hurt.
I did that, but didnt work for me. However every phone is different and every little bit helps.

Wondering if anyone else has this issue. My wifi is pretty weak on my EVO. i had strong connections before, and after, i rooted. But since i started running cm7 my wifi has become very weak. currently, my laptop has full bars, my friend has full bars on her intercept, but my EVO wifi shows only the dot in the wifi signal display is lit up.
Is this a known issue? and is there a fix? as i said, everything was fine when i was stock, unrooted and rooted.
running CM7.1.0, tiamat 4.0.8.
iv flashed several CM7 roms since rooting, all nightlies.
If this has been answered before i apologize. did a search for "wifi" and found no answers.
did u find a fix for this? i have the exact same problem
You may have low bars, as each device [phone] will register the connection strength, but as long as the data is there, nothing to complain about.
Try updating the radio. Somewhere on these forums there is a post with a combo zip that will update all of them all at the same time.
Sent from my PC36100 using XDA App
yeah, I had very poor wifi signal and 3g signal with cm7. Liked the look and feel of cm, but with poor wifi and signal strenght, along with gps not working and wifi tether unable to work, I went back to Fresh.
Hi, I've been following xda for a while but just recently registered. I searched the forums but didn't find any good answers/fixes.
In either case:
I've lost connectivity on my HTC EVO 4G. It's odd because the 3G signal indicator shows strong and the up/down arrows light up/dim. I'm running the latest CM7 supported nightly build and the Tiamat Kernel.
I was running a PRL for Verizon only roaming but heard rumors that 4G was in Phoenix. I did a backup of my ROM and restored a default android one then did the PRL update through the phone to get the most recent PRL from Sprint. Now in my CM7 rom and regular android ROM I can't connect to any data.
I tried re-wiping caches and restoring a second time to no avail.
Maybe I broke something in the ROM and just need to do a factory reset? Not a problem if that's necessary I have backups of all my stuff.
Any help for regaining service would be great! Thank you in advanced.
Well never mind I guess... just my luck as a Sysadmin once I ask about why it's broken it's fixed.
All data is back on my phone even after multiple reboots. Maybe PRL update didn't register on Sprints end? Don't know...
Thanks anyways everyone!
Happing to me too, it's a tower problem in my area. Nothing to do with your phone just Sprint's crappy network.
