Leaked 2.2 Data Connectivity Issues

I like many followed the instructions on the Leaked 2.2 to install Froyo.
I performing the rooted instructions requiring me to upgrade to Baseband version and verify that it's 2.05.00.06.11. This went fine and I successfully installed 2.2.
I noticed that I was having real connectivity issues. My bars would drop and connection would seem to cease. I often went from 3g to 1x connectivity and my apps could not connect without a reboot.
I reverted back to 2.1 but it kept the same baseband version 2.05.00.06.11.
I am still having the same connectivity issues.
So far I have seen people suggest dialing *288 to update the towers but that didnt work.
Other say toggling airplane mode fixed it for them. This is not a consistent fix for me.
Please add information here so we can try and find a fix.

I updated mine to the leaked 2.2 yesterday and I did lose my 3G for a few hours. I started to troubleshoot afterwards and toggling airplane mode would restore my 3g connectivity. I haven't noticed anything else that is troublesome so far, however, I am also missing some apps in the market.

There is a fix for the market problem -
I am trying to keep this thread about the connectivity issues. I suspect the firmware update did something bad. I am not running any roms or updates.

I'll have to try toggling airplane mode, I haven't tried that.
Yeah, I'm having issues too, also video recording has stopped working.

Not real sure if this is the same problem or not, but i'll post it here and we'll see. My phone seemed to have ZERO issues yesterday after the move to 2.2. Everything was working great (related to connections)
This morning, my alarm (on the phone) went off at 6:15am and I swiped it and got up, went and took a shower. While I was coming out I heard "Droid..." and was like, well that sux, a random reboot. A couple minutes later I came over to it and it was on the lock screen and the screen was dim like it was about to turn back off. I touched it to swipe and it was locked up and rebooted a second or so later.
Each time it came up, I had an X next to my signal meter and no WIFI or Data indicators. The process "system" kept dying and eventually causing the phone to reboot. I tried going into airplane mode / coming back out, but nothing.
As a last resort (so I could go to work) was to shut it down gracefully (reboots wouldn't let me get to hboot). And go and do a nandroid of the current setup and restore to yesterday right after I switched to 2.2.
After the nandroid finished I went ahead and rebooted it w/o a restore. This time the phone booted normally, no FC's and it's been running since then w/o any connection/reboot issues.
Obviously I'll be paying attention to this. It is actually nice having the "Droid..." so I know when it reboots

I havent had issue with the system process dying and rebooting. Just the incredibly annoying fluctuations in the bars and connectivity.
I would go to use my gTalk or gMail and it would say no internet connection. Or if you open the browser. Same thing.

No data
I updated the radio as well as the leaked 2.2 ROM. I now can't get any data. It will say there is a 3G connection but the market, Gmail, browser won't work. I was previously able to get data I haven't changed anything since.

I thought my data issue was using the Hybrid Altell/VZW prl, but after a *228 option 2 I am still having an issue. It seems to be when I shutdown the phone, turn it back on, the mobile data connection will not turn on. Toggling airplane mode will fix it, or sometimes a reboot fixes it.

Also having 3g/1x/no data issues post update to 2.2
Upgraded 8PM last night, all good until about 10am this morning, realized none of my apps were sync'd, then tried to use Opera/Market/Etc. all saying connectivity issues. The airplane mode on/off seems to fix it, wondering if its a select few and we should reflash or people are experiencing this across the board...

I had nearly the exact same thing happen to me. Flashed last night and then noticed the problem early today. A reboot of my phone fixed things; I'll continue to watch things closely.

Just got this for the first time as well.
I was just doing some configuration and needed to reboot - after doing so I did not have 3G and mobile network was ON in the settings.
Toggled to airplane mode and restarded - switched back after startup and 3G is back... but still this is troubling (I don't want there to be ANY problems haha)

All my Issues fixed with link @ bottom, thanks adrynalyne!

I am trying SkyRaiders rom to see if theres any improvements. I am on WiFi and its been working good so far. I will know more tomorrow.
Are you just getting the slow downs/disconnects on cell or also on WiFi? I had some weird WiFi issues last night so I thought it was both. Are you all getting it on all data connections or just the mobile network?

Make sure System Select in Mobile Network settings is on Home Only. I did this and I've had zero data connectivity issues with the leak. Had them when it was on Automatic.
Try it out.

I will join in and say I am also loosing 3G...it would be fine for a little then disappear for a while...toggling wifi and airplane mode helps, but I want it fixed and not have to rely on those.

Seems that Sky Raiders Rom has fixed the issues for me.

Which version? I am using 2.00 and I am having 3G connectivity issues. When I set my mobile networks from automatic to home, I only connect at 1X instead of 3G.
Is this fixed in Sky Raider 2.01?
UPDATE: I should have stated my original problem which was my 3G data connection was shutting down at random and the only way to get it back was to go in and out of airplane mode. I also JUST NOW updated to Sky Raider 2.01 and see that I don't have and data connection at present. A reboot did not work either. I'll keep trying things...
UPDATE2: Got it working...for some reason it was turned off in settings. Appears to be working fine now. I haven't seen any disconnects yet. Fingers crossed...
UPDATE3: It started doing it again under Sky Raider version 2.01. Don't know whether it's the new v2 radio or something with Froyo...

It is beginning to look like maybe this is a radio (2.05.00.06.11) problem an not a OS issue. But what I don't understand is why more people have not complained. I do live in a fringe signal area for 3G, perhaps that has something to do with triggering this problem. But I too have found that toggling airplane mode isn't a consistent fix.
If this is indeed a radio issue, then we may have to just live with it until a new radio version is released. Perhaps it would help if more people came forward and shared their experiences about this alleged problem. If it is only a few of us, then what might we have in common???

See here, 99% sure has to do with WiFi. I've been turning off WiFi before I leave the WiFi area I'm connected to and I've yet to loose data connectivity.
If this is all there is, I have a fully working 2.2 on my DInc now...don't really see a reason to upgrade to the official!

Incredible doesn't detect 3G

Hey all,
I got the July 27 leaked Froyo and went ahead and rooted to 2.2.
I have noticed a pretty serious buggy issue regarding the phone not detecting a 3G network so when I'm away from my wireless router, it only shows bars, no 1X or 3G.
I have two options at this point, one of which has done me no good. Perhaps someone can help me.
Option 1: Downgrade back to Android 2.1. (More on this later)
Option 2: Try and find a way to keep this version and get back on 3G.
Lemme explain: I tried placing the PB31IMG.zip on the SD card and going through recovery to return the phone to stock. Each time I attempted this, it told me the version was old and it failed. Is there a workaround on this or do I need to find a different stock ROM?
I used unrEVOked to root the phone and have not been trying to do any frivolous additions or subtractions. I just wanna be back on my 3G. Any and all help would be HIGHLY appreciated.
Thanks!

Did you try *228 and update your PRL?

Yes. It did not help.
Always have 3G coverage where I'm at too. So more than likely phone is issue unless a tower around here is down (which I highly doubt).

Toggle Airplane Mode on, then off.
JC

Sadly, toggling airplane mode has done nothing to help either.

Upgrade to the 8/1 version...see if that helps.
JC

Try shutting the phone off, then powering back on. Or possibly that combined with an airplane mode toggle. Also make sure your mobile network is on in the settings for wireless networks. This problem was common with the first leak. I have not had it happen since switching to the second leak of 2.2.

Considering the missing apps and media in the 8/1 Leak would it be ok to do Sky Raider or should I just try the 8/1 Leak done by aiccucs?

I believe mrozzeh also gave a link to the full version of the 8/1 leak, if you are concerned about missing apps/media...

Doing that update has not helped me.
I guess I'll have to go down to 2.1 again. However, as I said, it won't load the PB31IMG.zip. It says the file is old. Any ideas?

Stupid question....you did upgrade the radio right?

Yes. Radio is the 2.x baseband.
I would be VERY finicky to update that again as I do NOT want to brick my phone.

Ok, it seems I have found a bit of the issue that is causing it. My phone number and IMSI are not detected as my current phone number. Is there a way to program this or is it an issue where I'll have to have it reprogrammed by the local Verizon rep?

try a *228 and option 1 so the phone is reprogrammed. then do a test call to your vm(*86) and make sure it connects, you should not see the 3G symbol, when you end the call, the 3G should be displayed...give it a whirl

This did not work. There has to be a way to program the phone number into the phone. Any ideas?

i've been having this same issue... messing with airplane mode and rebooting a few times got it to fix... *228 and option 2 worked sometimes. just loaded up Adryns new evo hybrid rom, working fine so far (the problem was rare, maybe twice a day tops) and did *228 1, we shall see!

To no avail on these. I think I'm going to have to see a rep tomorrow and see if we can get the phone number (my actual phone number) programmed back into the phone. I think that's a VZW thing as I'm sure they won't run me through the methods to program a phone number.
I hate that I have to go back to Big Red over this, but it is important for me to have this phone up and running. Besides internet, I have NO other form of contact.

3g issue
I had the same problem and so have many others, I flashed Skyraider Rom and problem is gone so we know its not a buggy radio, I don't think there is a fix right now, but I've never seen a Rom so stable as the new Skyraider, so you might wanna think about flashing that Rom.

Coincidence. I've heard the same with my roms, from both ends of the spectrum. Its for sure a buggy radio, and how it interacts with Froyo. Once we get a 100% Froyo ready radio, I doubt we will ever hear about the issue again.

This is the first I've heard of someone not being able to get the 3G connection back at all. Is that what you are describing? I had it not turn on, then come back after a *228/2 or power cycle - but it always came back on. Just curious but are you on an Alltel plan by chance?
Can you make calls Contra? Did you pay your phone bill?? Are you wiping all data before flashing? Try the full second leak that they added to that post. I've been using it and haven't had the 3G drop in two days now. I just took that rom and removed a handful of apps I would never use. It's working quite well.

3G stops switching back after wifi?

This is a strange one. I have been using Fresh Evo 3.2.0.0 rom for almost a month and it works great. I wanted to try another rom so I tried the VirusRom... it was good but I liked Fresh better. So reflashed my Nandroid image and all was well.
But then I started seeing a lot of failed connections to the market and noticed that my 3G was not connecting. I live in Chicago so I am fully covered by 3G in this area, and even 4G in many spots. Usually when I leave a wifi area, the phone switches back to 3G almost instantly. But ever since nandroiding back to the Fresh Evo 3.2.0.0 rom, it only works after a reboot. As soon as I hit a wifi zone and then lose it, 3G doesn't switch back on.
4G and Wifi both work, but if I disable both wifi and 4g.. 3g doesn't come back without a reboot.
I've even switched off the Mobile network using the widget and the power button menu.. no luck. Only a reboot brings it back.
So then I even did the trick to get my PRI up to 1.40 and that worked fine. But no change in the behavior of 3G. When I reboot and 3G is working, it works great as usual. Just not sure why the switching no longer works. I even tried switching back to the rooted sprint stock rom.. same deal.
Anyone else having any issues?

yes, I have noticed this at times. Just happened to me. Failed connection when switching off 4g to 3g. Using fresh 3.2. But I noticed this as well on other roms. I had to reboot each time to get 3g working again. I also reset my data connection last night but it obviously didnt work.

I've been having issues with my 3G for the past two days. Similar story, I did and Nand restore and that is when it started.
I am getting an error code 67 everytime I switch from Wifi, 4G or even when I reboot to try and fix this. Usually if I let it sit it will come back, but the error message popping up is quite annoying.

Wish I had something more helpful to say, but I can just add that I'm having the same problems switching from wifi to 3g. Even after 3g turns on it will sometimes turn off again randomly and I will have no connection. I'm also running fresh. In addition my 3g signals are quite week. kinda a mess...

Weird. My phone did this today for the first time. The thing is, I've been on Fresh 3.2 for a month now, and I flashed the latest Baked Snack rom yesterday to test it out. It never did it while I was on Fresh, but today after turning off WiFi, it wouldn't connect to 3G for anything. No text or data transfer at all. After I rebooted it, it started working again, but my phone never did this while I was on Fresh.

I am having the same problem and I am using Fresh 3.2 as well. I did go to a different rom but then went back to Fresh's rom and that is when it starting happening to me. It will only pick up 3g now and then and even when it does my speed is super slow. Hoping someone comes up with a fix as I made my own post but no one seems to feel the need to reply to it.

Theories...
Same here. I'm on Baked Snack 1.7x
I know Fresh and Hero both use some of the same components. I flashed to Cyano and have had no problems with the 3G radio. It's very snappy switching on and off after wifi connects and disconnects.
I do know there have been one or two issues with the radio with people who are on the 3.28.651.x roms. (for instance, if you enable 4G then disable, sometimes it randomly turns off and on without you knowing until you restart)
So my guess is maybe the 3.28.651.x series is glitchy. You guys want to try going back to 3.26.651.6 and do some testing?

happened to me on stock. Had to reboot the phone to fix it.

This seems to be working for me today with no problems so far. I am wondering if a tower was down with Sprint putting up the 4g around my city. Will keep posted if it happens again but seems to be running like normal now.

This has to be network issues maybe the latest PRL.
Mine has did the same last couple days also on power on , it takes longer for 3G icon to kick in.
Signal flux has been occurring more then norm fast download - Upload speeds taking hit some parts of the day.

I am on 3.26.651.6 build and this was happening. I am no longer having any problems with this. I do feel this might have been a problem Sprint's servers were having. Seems like everyone started having the problem right around the same time.

It must be... Going to an older PRL didn't help, and there are a bunch of forum topics being created about this on other forums as well. Guess it's time to play the waiting game.
My issue is so bad right now even if I restart my phone, it doesn't even get data connection right away. 10 minutes waiting now and error code 67's keep popping up.

This just happened to me today. It took me awhile to connect the error statement to the fact the 3g didn't turn on after I turned off wifi. But I was able to press the 'data connection' button on the switchpro widget to turn 3g back on.

That is how I got it working a little bit last evening but as I said in my last statement it is finally working and has been all day. Not sure what the deal actually was as I did not change anything since 2 evenings ago. I am thinking that Sprint is doing something which is messing everyone up at one point or another.

Rooted OTA 2.3.3 Loosing Data

So I recently updated to the OTA rooted 2.3.3 by clearing all data, sbfing back to 2.2 and then updating to 2.3.3 OTA rooted. I have noticed recently that every other morning or so my data connection is just gone. I can turn airplane mode on and off and it does not come back, wifi works fine. However if i disconnect from wifi I get no data and I can't make a call or send receive text messages until after I reboot, just wondering if anyone else has been experiencing this and if there is a solution or if I should just clear the data on the phone and see if the issue goes away.

That is not good. You may want to SBF again to see if that works

I have the same problem on my non-rooted droid x. data connection goes away and doesn't ever come back until you reboot. I've seen other people have this problem in a few other forums also...

Well I did a factory reset and install only launcher pro and google voice. Will use like that for a few days and see if it happens again.

I sorta had this issue last week -- mine was dropping from 3g to 1x in my daytime location --i am here everyday so I'm familiar with the speeds/signal strength for this area.
Also I had never had this issue... ever. I was on the .595 GB leak, but I sbf back to .340 (didnt root) and STILL had the issue. I did data and cache wipes in recovery while on .595 plus a factory reset even after the froyo SBF.
So nothing worked..... GB, Froyo, rooted, non-rooted, factory resets, data roaming disable ... it still would drop 3g for 1x. This was just out of the blue, I've had the phone since Dec. 2010
I thought it might be a tower issue, so I suffered with this nonsense for 3 days, knowing that VZW would likely fix tower issues in that time.
After additional research, I found those saying a battery pull would do the trick. Well heck, after all that angst and effort a simple battery pull did it !
Not one problem since. Try the Battery pull !

Curious as to why a battery pull would do anything different than a reboot?

It isnt any different. I've had this happen a few times and it keeps coming back in normally bad signal areas, but not every time. I have also had random reboot when the phone is in my pocket, unlike froyo where the reboorts happened when I was doing something important. I suppose that is progress then.

[Q] Loosing Data Service

This is my 3rd Sprint S4 over the past few months. All of the devices are loosing the 3g icon but will show bars. Voice and text works fine, data and 4g does not, i have noticed it usually happens when i leave a WiFi area and it has trouble switching back over to cell data. I can reboot the phone and about 80% of the times it will return to normal. I have used odin to reload to factory. I had my phone rooted only and recently install the Triforce rom to see if it was a software or Kernel issue. Same thing is happening on that rom as well. It doesnt matter where i am so i dont beleive its a tower issue. Any idea?

This happens to me as well. Just Sprint being crappy. Try turning airplane mode on and off, same effect as a reboot but faster.

I tried the airplane mode toggle but didnt seem to fix it. If i use even the "Hot reboot" option in triforce rom that doesnt fix it either.

Assuming this this is the same issue I always experience, there is no fix. It's a network thing. Is there 4G in your area?
What happens to me is my phone will be on 3G, then start receiving 4G, but it doesn't recognize that the data service is now different, so nothing works for 15+ minutes or until I toggle airplane mode on/off.
I take it you've tried just turning WiFi off?

Haha, yea, welcome to Sprint. Enjoy losing data when it's least convenient (such as when you need to use navigation or missed your exit and need to be rerouted). Oh well, the price we pay for unlimited data, right?

I have noticed the same thing since I activated my LTE radio. LTE is expanding in my area so I constantly go in and out of 3G and LTE service. Sometimes when this happens data just ****ing stops working until I enter airplane mode and then come back out of it (a reset works as well). For some reason (or it is just a coincidence) The problem has amplified since installing 4.3. Has anyone else noticed an increase in this problem since upgrading? This is absolutely a Sprint problem? Do we know that people have this same issue with other Sprint phones?

I have the same problem. From wifi to f data takes a little bit of time for it to switch over especially since the data toggle is gone with the 4.3 update. Unlimited plan is water downed from my experience compared to tmoblie. But tmoblie service was horrible.

Well Sprint's speed has always been an issue for most of us. That is no surprise. I at least expect to to work AT ALL which apparently it is incapable of doing recently.

I can reboot the phone and about 80% of the times it will return to normal. I have used odin to reload to factory. I had my phone rooted only and recently install the Triforce rom to see if it was a software or Kernel issue. Same thing is happening on that rom as well. It doesnt matter where i am so i dont beleive its a tower issue. Any idea?

If wifi is on 3g/4g is not there,, turn off wifi and you should see icon,, if you see bars it's most likely working :sly:
Edit just re read your post, I have the same issues sometimes and as posted above toggling on and off typical works for me,, good luck
Also is your network set to
CDMA/LTE/EVDO? Just throwing out ideas

I get this issue all the time & I have to do a battery pull to get my phone working again. Anyone flash a new modem which fixes this? The SGS4 is 10x worse than my HTC EVO 3D was with this issue.

Seems like a hardware problem based on your description. I am fully convinced that this whole flashing modems things is just a feel-good measure for people who have exhausted all other options. It was big in the Galaxy S2 days, but I have never seen any measurable difference between modems in any meaningful metric on that device. At least not one that could not be attributed to other factors such as signal quality and network load, and nothing consistent. A different modem isn't going to fix a hardware fault or magically improve Sprint's awful service.
