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!

Nexus S total network loss.

So my girlfriend's Nexus S has been losing the entire voice and data network and going into no service mode, no biggie at first, just cycle airplane mode, then it went on to rebooting because you would select airplane mode from the power off menu but it would not check the box in the wireless settings menu.
After the reboot the box would show checked and airplane mode could be disabled and the service would resume. The the phone started getting stuck in airplane mode and not even rebooting it would bring it out the first few times, then it got to the point of resetting the phone, a wipe cache/data reset didn't fixed it. So off to T-Mobile for a new sim card. Rebooted the network immediately. And as of last night its back in full force and now not even a new sim will resurrect the network.
Have tried wiping, reflashing stock 2.3.3, new sim again, multiple resets, had to get an toggle widget to get it out of airplane mode and still a dead network, all this time the network in the *#*#4636#*#* menu showing unknown and is not able to be changed and reverts back to unknown immediately, OEM specifics settings button is greyed out and you are not able to disable the radio either.
While I'm going to call Samsung on Monday and I guess send the phone off, I worry about mine because it too does it but only once a month or so, but I do constantly have issues resurrecting the phone from airplane mode at times because the box will not be checked in the wireless settings menu but I can see the airplane instead of network bars, problem persists with reboots sometimes.
I also would like to add that even when the box is not checked in the wireless settings menu for airplane mode, if you click it it just hangs forever and will try to select but never will and stays grey like its turning everything off, but if the scren goes off its like you never tried.
Has anyone else seen this? I have seen a lot of people with data network issues or having to reboot to get voice network back but nothing as bad as I'm experiencing.
Both our phones are and have been completely stock and unmodified.
Thankfully we still have her Vibrant and in case I need to send mine in my Nexus One.

Have you tried restoring from another persons' pre-made nandroid backup?
This over-writes the radio firmware, you should give it a go!
I also found that I had problems on 2.3.3, however reverting to 2.3.2 gave me no problems!
Just contact me if you need any help restoring from a nandroid backup or finding the 2.3.2 backup files

Is that true? I am just on the verge of calling samsung. My phone won't connect to or display any available networks, and is pretty much now dumbed down to a small tablet. I've tried everything except another persons nandroid backup. I've been told to stay away from flashing another persons... but I'm really desperate.
If you could provide me with a backup, that would be awesome.

I'm having identical problem.
It was working fine yesterday, look back to it and now it's got no mobile network, nothing. Just the no bars and cross symbol. I've tried wiping dalvik cache, reflashing the radio, wiping data/factory reset, reflashing the rom, restoring with a backup (Backup of when I first rooted the phone) and still no signal. Nothing has worked..
Anyone got ideas on how to fix this issue?

Can you search for and view available networks?

This sounds like the CM7 powerwidget problem (3g/2g) I used it and I loss all network, phone process will crash every second, however if your phones are stock I can't think in anything causing it.
For CM7 you'll have to reflash and delete userdata or edit the sql database for the providers and change a value to 0, but you need root.
When I went to *#*4636.... my preferred service was "unknown" too, but now it is OK.

Try to dail:
*#*#4636#*#*
and find your network information.

Nope. Sits their 'searching' but nothing shows up.
In, *#*#4636#*#*, it gives little to no information. Just says nothing for current network and for GSM disconnects it has,
Sate: DvInactiveState
disconnected with last try
at 9:59AM
fail because No Error
And that time never changes, stays at 9:59AM.
As my above post suggested, I've tried doing a factory reset and reflashing. I don't think I use CM.. I flashed with Oxygen 2.1.6 (using it's kernel) but I restored to Oxygen rom and trinity kernel after it didn't work.

Ok, it'd be great if you worked something out. I'm so glad i'm not the only person with this issue!

Anyone had any breakthroughs? *hopeful*

I wouldn't call it a breakthrough but I got somewhere!
Ended up putting a extremely thin piece of wire into the external antenna port at the back of the phone. Wasn't too keen on doing this, but my phone now has reception isn't stuck at the dreaded -113dbm.
The reception isn't good, but it's enough to send texts and have calls.
Although the area needs quite good reception for me to receive anything, and it's extremely sensitive. To get 3 bars in a place where I usually get full bars, I have to be outside. While inside it's reduced to none or 1 bar, which is enough to send/receive texts and a sort of lagging phone call (did a few tests). As mentioned before extremely sensitive. The phone seems to like it better when it's up-right. In the middle of the CBD at Brisbane I get full reception and 3G, which is fine but in the places where you usually get 2 bars, you get no signal at all, unless you're outside.
So this is hardly a fix. I will most likely be sending it to Samsung to get it actually fixed. Either that or get it fixed the same day and pay probably close to $100 so I don't have to wait 2 months waiting for Samsung to twiddle their thumbs.

Thats awesome! But I'm going to post mine off to Samsung USA tomorrow, which will take forever considering international shipping. Where could you get it fixed same-day? I'm going to try this wire thing

So it can't be a software issue, but maybe the rom overloaded the antenna and fried it or something? I'm glad we've got that far.

I've seen that nexus s has a problem like the iphone, the antenna gate. Try take the phone with the left hand looking to no touch the rear of the softkeys

Its more serious than that my friend! Thanks anyway

I got a quote from a place in Brissy called "FixMyMobile" and they said if they can fix it, it will cost $99. Although I'll get quotes from different places (if I find them) and see what they charge however I don't think I will be able to get cheaper, most likely around the same price..
So I may do that to not wait the ridiculous time it will take to get it back from Samsung.. Not sure on places in NZ though.
Yeah it seems like a hardware issue definitely. I eventually reverted the phone back to stock everything and it still happened, so that there shouts hardware issue.

3g disconnects randomly GB .588

I am running .588 and I restored my data after coming from the original gb (.573) leak. I loose my 3g connection at least once a day. Sometime when I toggle the airplane mode it works and I connect back to 3g, but i that does not work I just reboot the phone. Anyone else having this issue? We need feedback to see if its a hardware or software issue in gb. The reason I cannot confirm if it is s/w or h/w issue I received a replacement phone when the .588 came out. I cannot compare both builds with same device. I am going to revert to .573 to see if it continues. I will post back with outcome.
Thanks in advance

The airplane mode does not work for me. Someone recommended to use an app called signal refresh. My main concern is if its a s/w of h/w.

I have this problem, as well. I used the Monster SBF to get to .340, installed GB, and restored only user apps with Titatium Backup. Airplane mode works for me sometimes. Every now and then my phone will go into airplane mode and lock up, forcing me to do a battery pull...

I was on the old gb leak and restored data in clockwork after moving to the new gb. I haven't had the problem yet today. (Knock on wood)

Same
I'm seeing the 3G drop as well. Of course i only notice it since i'm tethering my wifi xoom to the droid (method irrelevant). Airplane mode works for me.

Mine drops out and stays out all the damn time. Sometimes airplane toggling is enough, sometimes I have to re-boot the phone and then toggle airplane mode and other times just turning WiFi off works well enough. It happens on my Wife's D2 constantly as well. We've missed plenty of calls (google voice pops up letting me know I have messages from missed calls even though the phone didn't ring and we have big problems texting throughout the day).
We're both going back to Liberty right now cuz this is BS. Hopefully this will get fleshed out for the final OTA and I can see why Verizon hasn't approved either leak yet. And even more hopefully it's not the new radio, and if it is hopefully SBF-ing back to 340 will fix it. If it doesn't, do any of the older SBF's work with the 340/588 bootloaders and also contain older radio firmware?

Update:
re-flashed GB. went two days with no signal problems, but this morning I lost my 3g connection. I have a feeling that it has to do with the hand-off between the wifi and 3g connection. I have tried to duplicate the issue but I cannot duplicate it. Also one thing I notice is when my 3g is not working and only shows the 4 grey bars I cannot make outgoing calls but calls do come in. Weird....

Fascinate poor reception

My verizon fascinate has always had good reception, even with different roms and kernels. I ran into something last week that made me have to factory wipe. Once I get root back and back to SC 2.9 and EC01 modem I've not been getting 3g service on a consistant basis. I can't access internet usually, email, or anything else relying on 3g. I can make calls, text, GPS. I tried different roms, kernels, reflashed EB01 radio, EC01 radio. No difference. What else can I try?

Did you set Airplane mode after flashing SC? I never had a problem but some people reported that they had to go into Airplane mode momentarily to correct reception issues.

Apologies if this is too basic -- did you already do the OTA *228, option 1, reboot, *228, option 2, reboot sequence? Hope this helps...

I tried Airplane mode and I had already tried *228. Neither attempt helped. I appreciate the suggestions though. I'm beginning to wonder if it's a Verizon problem. If I take it to the Verizon store for troubleshooting will it reflect that it is rooted? I know the warranty is not valid but will they refuse to help since it's rooted? I wonder if it would help to do a factory wipe again and start from scratch?

yes do this, or you can just do option 2 anytime you feel like it
this updates the Tower Roaming list for your area (from what I read)

Sadly, nothing I have ever tried has improved reception on my Fascinate. I hate to say it but I believe it's hardware at fault here due to a weak radio. It at times has gone from full bars 3G to 1x and back and the jumping up and down never stops.

mine has always had good reception but something happened and I have none where the day before I had strong 3g service. its usually not even showing the 1g/3g transfer bars indicator, just one or two signal bars without the 3g indicator. I used to use the email and internet at home before we got wifi to hook-up to but since last Saturday I can't connect at all without the wifi. So its not an issue of never having good service because I did before Saturday.

Issue with data connection dropping and text messages

Had regular galaxy s4 from att since it came out, never did any rooting or anything, updating to kitkat Ota when it was released and had no issues until about a week ago. I did a factory data reset because of too much junk on the phone and wanted to reorganize a bit, backed up everything using kies 3 and ever since then my data/signal cuts out randomly everyday, all day long. The more I text I noticed the more it drops, and then goes from LTE to 4g and it'll stay that way until some random amount of time, disconnect again, back to LTE once in a while but mostly be 4G. I heard of some issues with the kitkat update causing various issues like this but don't understand how a simple factory reset and restore screwed it all up or if it's even that. Tried full format, reflashing entire stock firmware and has done absolutely nothing for remedying the problem. Is it possible it's a sim card issue?

I have been having the same problems since I took an OTA update. LTE is very intermittent in places I know it is available and I randomly lose my cell connection for brief periods, which is a huge pain for SMS. I just flashed NB1 with ODIN and everything worked for the brief time before I updated to NC1 (LTE, no connection drop). When I updated to NC1 I started experiencing problems again. I subsequently tried flashing back to the NB1 modem to no avail
I tried ATT support at one point and they reset some stuff on their end (a while ago so I don't remember what) but that did nothing.
Anyone with any insight here would be my hero. This has been plaguing me since december.
Update: Tried re-flashing NC1 modem twice via ODIN with manual reboot. Still no LTE, not sure about connection drops yet.

Went to att store yesterday, thought maybe bad sim card, they replaced it and problem still persists... Looks like I'm getting the note 4 next month cause this is driving me crazy, so I guess I just need to put up with it until then.

Had regular galaxy s4 from att since it came out, never did any rooting or anything, updating to kitkat Ota when it was released and had no issues until about a week ago. I did a factory data reset because of too much junk on the phone and wanted to reorganize a bit, backed up everything using kies 3 and ever since then my data/signal cuts out randomly everyday, all day long. The more I text I noticed the more it drops, and then goes from LTE to 4g and it'll stay that way until some random amount of time, disconnect again, back to LTE once in a while but mostly be 4G. I heard of some issues with the kitkat update causing various issues like this but don't understand how a simple factory reset and restore screwed it all up or if it's even that. Tried full format, reflashing entire stock firmware and has done absolutely nothing for remedying the problem. Is it possible it's a sim card issue?

+2 to this issue. My wife and I both have the same problem as you've described, and it's gotten progressively worse with time. The worst part is that the phone seems to think that cellular connectivity is still there as I still have bars. However, data, phone and text capabilities are all dead. The only fix is a reboot, and it's short lived.
I've read on another forum that disabling 3G and 4G eliminates the problem, but then you're stuck with basically no mobile data...
Anyone with advice, I'm willing to experiment!!!

It's hard to believe no one else is seeing this problem, or attempting to resolve it...

Wiped x3, flashed MDB mode and Odin'd back to stock MDB ROM. Let sit for an hour, then flashed back to stock NC1 ROM & Modem. Modem hang in less than a day...anyone else have any ideas how to fix these modem hangs? I don't have any ideas left.

Got the same problem. Mine started happening on MK2, so I updated to NB1 then immediately NC1. No change at all. I was concerned that it was because I'd rooted and was running Xposed framework and a bunch of modules. I was about to flashback to stock, but after reading some of you folks issues, I won't bother.
Looks like an upgrade sooner than later is in order.
