Sprint EVO.. Latest Cyanogen and Radio.. Stuck on 1x.. HELP!

New to this stuff, but have managed to fumble through getting phone rooted, flashed and functional... to a degree.
I have a HTC EVO on the Sprint network.
Android 2.3.3
Cyangen Kernel 2.6.37.4
Mod ver. 7.0.3.1
Baseband 2.15.00.04.08
So with everything up to date as far as i know I am stuck with a '1x' for a signal.
My mom has the exact same phone except its not rooted. Stock everything and shes getting a 3g signal when shes in town.
So Im stuck here. Anyone have a clue?

Im fairly new here and by no means a dev but i believe its because you have cyanogen its telling you the actual speed you have. while the stock evo only says 3G but is really only on 1x. try running speedtest on both devices.
-also please correct me if im wrong, read this somewhere and am currently experiencing it aswell

thanks ocruz301
Can anyone else chime in and verify this?

try re-configuring your roaming capabilities. Your issue is unlikely to do with CM7.

I have looked through the roaming menu and i dont see anything that looks incorrect.
Is there anything in particular i should be looking for?

Speedtest.net results:
average from several different locations.. 15kB
around the same for uploads..
600ish latency

I have travelled a little over 500 miles around Tennessee Arkansas and Mississippi and Im getting the same thing everywhere..
Anyone?.. anyone?

So these are the steps i have taken thus far:
-updated to latest cm7
-updated to latest radio
no go
flashed to stock rom and updated prl
ran speed test.. 15kB up/down.. EVEN THOUGH it SAYS 3g
flashed back to cm7
speed test.. 15kB
Does no one else have a freakin' EVO that can just chime in and let me know im the only asshole with this issue?

I have a somewhat same problem. My phone would drop to 1x every 10 to 20 minutes and stay there for a few minutes then go back to 3g. It does this throughout the day. Luckily I have 4G in most of my area and that helps me to avoid using 3g. The moment I turn off 4g it starts doing it again. It started a few weeks ago and I don't know what caused it. Like you have have tried different Roms and Radios but no help. I'll gonna try to unroot and go back to Sprint Rom and see it that helps.

hmmmm
I run king cocoa II rom and I thnk its the absolute best ive seen but its also froyo not gingerbread

Anyone, I am having the same issue, no matter which ROM I flashed, and whic kernel PRI or PRL I used, my speed is only 128K max with 1x icon

[Q] Problems with the Full MR2 leak - 4G radio instability

Very odd problem with this new full MR2, probably radio related. When i upgraded it obviously did the full wipe so I know it's not a software interfering. It's pretty much a fresh reset since 1pm.
Anyways i keep losing connectivity to 4g. it flickers to 4g, then 3g, then 1x. Then back to 4g for a second, then it just loses connectivity to the internet totally but shows full bars. Now i'm back at 1x.
I am sitting smack in the middle of NYC where there is always full 4g & 3g bars. Anyone else experiencing this problem? I've done numerous reboots, put my phone in/out of airplane mode, etc but i can't hold a 4g signal for the life of me. Didn't have this problem in the AM before i upgraded. It's now flickering between no internet connectivity and 1x as i type this. I wonder if this is network related or the new firmware?

I was having that issue before the updates (the first one) when I was in NYC. I honestly think it may be the 4g network. the way I solved it was putting my phone on CDMA(auto) and it just held 3g.

I was having that same issue running The Perfect Storm. I downgraded the radio and went back to BAMF Remix and have had NO 4G issues. Good connection, great speed, and it never loses the 4G connection.

4g has been fine for me running the MR2 radio with flyweight ROM. I'm in Florida though, not NY...

I am in NYC and had the same problem....
I even flashed the first Ginger radio and still had the same problem...
10 min ago I reloaded the MR2 radio and I am getting 4g now....
I am 99.999999% sure it was the VZ network!
EDIT::: just went back to 1x.....I am sure it is the VZ network...just have to wait ait out

Interesting...I thought I would try this update again this morning with a different ROM (Das BAMF 2.0 - 5) and have had no issues at all. 4G is constantly connected with no drops. I'm not sure if something happened with the initial install or if it was an issue with the ROM I was using it with. Anyway, all is good.

Try powering down..pull battery and LTE sim. Reinstall them and power up.
ridin the lightning

sorry to necro, but this is the first relevant thread i found in search
i am in a similar situation, before rooting (stock thunderbolt), i could exaggerate and say i didn't even know what the 3G icon looked like, constant 4GLTE uptime in washington, DC
i'm using INJ3CT3DTH3ORY (pardon me if i have stylized the name incorrectly) with an OVA MR2, and now i'm constantly 3G. i've tried every setting under "set preferred network." if i do LTE only, it'll show 4GLTE for maybe half a minute, and then fall into 1X. if i do CDMA + LTE/EvDo auto, it'll show 4GLTE for a similarly short amount of time, then fall into 3G. all the other settings deal with 3G only if i remember correctly, so i'm not even bothering to mention those.
thinking it might have been the radio, i tried flashing MR2.5 and MR.627, both giving me the same result.
any ideas?
edit: found this thread, seems to be related as well (showing some effort here) http://forum.xda-developers.com/showthread.php?t=1178285

I am not experiencing these problems with BAMF 1.86

i9020A (ATT) completely lost 3G on all ROMs, help!

I've completely lost 3G ability on my NS, and I'm not sure what happened.
Here's my order of tweaks:
CM7 nightly (with 3G)
MIUI (with 3G)
ICS rom from SDK (no more 3G!)
ICS from kwiboo (no 3G)
ICS from koush (no 3G)
CM7 stable (no 3G)
I guess sometime during my playtime with the ICS from SDK build, something messed something up and subsequently I cannot get 3G anymore, regardless of ROM.
I'm not sure where even to begin troubleshooting.
- Yes, "use only 2G networks" is unchecked
- My APN should be correct, as they are the ones that loaded automatically from the ROMs. That has always worked before
Anyone have any ideas? I'm desperate for help. I haven't had 3G for what feels like a month!

Here http://forum.xda-developers.com/showthread.php?p=19424857 in this post there is a link to the radios try flashing one of those to see if that fixes things. If not try flashing a stock unrooted rom and start over

You know what? A new radio worked! I don't know why I didn't think of it before. Seems so easy in hindsight.
This brings up another interesting thing. Seems like a lot of the radios that used to give me 3g don't give it to me anymore, including the most popular ones people are using. That's weird...
edit: Actually, no radio issues anymore. My old radio gets 3g again, as well as others. I just needed to rotate the radio versions a few times and reboot a few more times and it fixed itself. Totally weird, but no more problems!

I had the same issue on AT&T 2 nights ago. It turned out that it was an AT&T network issue which was confirmed by tech. support.

[Q] Radio disconnects!

Here is whats happening! I go into an awful area with no cell service and when i return into an area with good service... It shows all my bars, 3G icon, but its all grayed out and will not return with color... Also i have no data connectivity at all. The only way to resolve this problem is a reboot. I have the Nexus s 4G KL1 radio... This has happened twice in 2 days. Can anybody tell me what this could be? I tried the KL2 radio and the same thing happened. So I went back to KL1. I am running Cyanogenmod 7.1 stable. Any help would be appreciated, I like this phone and dont want to have to go back to my slow Evo.

Happens on ICS ROMs. I switched back to GB because of that issue.

OHHH ok that makes sense since i was on an ics rom... That sux i love the ics roms to. Is this an issue they know about and are working on?

Yes I am sure the devs know about this issue. A lot of people already reported this issue on the ROM's threads. I think there was a fix in the CM9 repositories that was merged this week.

well thats good news since were i live its not good service and im in and out of service a lot. Thanks for chiming in and letting me know! I was wondering if i had a bad radio or some thing lol...

This happens to my I9020T as well (with stock ICS, Pixel ROM, and Brainmaster's Stock and MIUI ICS ROMs). So, it's definitely an ICS issue. My network connection won't reconnect after I ride the subway (underground, where there's no signal) for about an hour. The only way to fix it is by doing a reboot (enabling and disabling Airplane mode doesn't fix it).
I just tried switching radios: from KI1 to KF1. I'll update on the result later tonight.

Sounds like exactly what happened to me.
I went back to gingerbread. I haven't had the issue since!

Just out of curiosity have you tried the KL2 radio with CM9/Latest nightly and then toggle your Data Enabled or the data roaming? If that works it might save you the reboot. Settings, wireless & Networks/more, Mobile networks, Data enabled.
You could try toggling the data roaming too.

Yup tried it already

Ok it was worth a shot. When I travel to the UP, I get no data service what so ever. So I feel your pain.

I've tried enabling-disabling Data as well, and it doesn't fix it.
The weird thing is the same issue happened to my girlfriend's T-Mobile G2 with Gingerbread last week, when I unchecked the "Use only 2G network" setting on her phone and forgot to check it back. So, when she told me the issue when she got home, I re-enabled the "Use only 2G network" setting again, and her phone haven't had the reconnect issue ever since.
So, my speculation right now is this reconnect to network failure issue has something to do with the Nexus S' 3G/4G network type setting.

I definitely think you're right

I am having somewhat the same problem.
My phone keeps switching from UMTS:3 to HSDPA and back to UMTS:3
This is draining the hell out of my battery. But when I have it on EDGE 2G I'm getting good battery life.

the issue is not that big for me. I just give it a few moments with it in sleep and when I go to use it again it fixes its self.

Update!!!! I have since switch off of the I c s rom. I have not had the incident happen even 1 time since doing so. I am totally convinced it's on ice cream sandwich roms.

Just an update: Switching radios didn't fix it. Had the same issue after taking the subway yesterday.

I doubt the radio would make a difference. I think the issue lies in the Phone application.
I could be misinformed here, but if i recall correctly, our phones radio is relatively stupid as far as radios go, and the intelligent parts are actually done as a part of the phone application. This only applies to CDMA Variants of the Nexus S, but it could be the reason that the ICS update was pulled (As thats where CM and others get the ICS version of the phone app.).

After taking the subway for about an hour last night, my NS actually reconnected when I got back up to ground level. One thing that I didn't do is listen to music (PowerAmp); I was always listening to music when I had those network reconnect issues.
Anyway, I hope this issue gets fixed in the upcoming official Google ICS update, that should be released in a few weeks*.

I've found that if you just stick it in airplane mode when you are about to go into known no service area and then take it out of ap mode when you know you have a signal you can save from having to reboot to reconnect.
My building at work is a tomb for sprints signal and it works for me every day w/o rebooting ...

To all of you having network reconnect issues -- do you use any battery saving apps, like JuideDefender or GreenPower? I use one, and I'm thinking that its network toggling internal API method has something to do with this issue.
Yesterday, I disabled my GreenPower app right before I took the subway, in which my NS couldn't receive any network signal for about an hour. Then, when I went back up to ground level my NS was able to reconnect to my network successfully.
I'll do the same test later after work and update back tonight.

No 3G / EvDo

For some reason I cannot connect to 3G. I can only get 4G or 1x. I've been running cm10 for awhile and I've switched back and forth between different ROMs including back to stock and other TouchWiz ROMs. I've not really sure when this happened because I didn't really notice at first, seeing as how I'm in a strong LTE area. I've tried using phone info and using the settings in cm10 under mobile networks. The strangest part of it is that in phone info, if I set it to EvDo only, my bars go empty.
I've updated to the latest modem, and like I said, I've tried different ROMs and even different kernels. I've used Odin to get all the way back to stock unrooted and everything. I can't figure out what could be causing this.
I lost my IMEI weeks ago but got it back so I don't think that's the issue.
Any help that I get can get would be really appreciated.
Thanks
