Random Dropping mobile network connection...

I rooted my Evo a while back. No problems. After a few months I started getting these weird problems where I would get no 3g network at all. I was running Caulkins ROM and now MikFROYO ROM. Still the same problems, on both.
Flashed the bundle radio update pack (comb) from this link:
http://forum.xda-developers.com/showthread.php?t=715485
Still have this intermitten issue. Nothing regarding the internet or even calls would work. I can't make phone calls, get on the internet, facebook apps stop syncing everything. The bars on top become all empty. Not 1 bar at all.
I try restarting and even shutdown and turn the phone back on but none of this works... I even did my prl/profile etc. updates and still. The only way to get everything back up is to wait. After a while everything kicks back in and it's working again.
Can anyone help me with this? It's really frustrating and I've had this phone from release day. It only started this recently and it's intermittent and hard to pinpoint anything structured with why and when this would happen...

No one else has ever had this problem?

[Q] Evo CM7 won't call, won't do data (after several days of working)

I recently rooted my Evo and put CM7 nightly 12 on it. All was well, I even installed the Savaged Zen kernel. Even better. Just yesterday I updated to CM7 RC2 to give it a shot. Today I went to work and had to drive to a remote area where I don't get service, so I put my Evo in airplane mode to save battery life. (this was after having it overheat while charging, could be a hardware issue) At the end of the day I turned the 3G radio back on and nothing... It connects and disconnects to the tower. It will not send data and it will not place phone calls on the 3G connection (WiFi works). I did a restore back to nightly 12 to see if maybe it was a problem with the OS. Nothing. A few hours ago it began functioning again, but after checking it a few minutes ago I have discovered it is back to no connection. (the signal bars bounce between nothing and full, but never shows the X for no signal) Has anyone else had an issue like this? Should I restore back to sense and unroot to take advantage of my warranty? If this has already been posted before please direct me to the right thread.

I'm having the same problem. I installed Cyanogen RC 2 and had no problem since it came out. I went on vacation to a beach, and during my trip I switched it on to airplane mode since I was in a remote location. After turning it back on, I noticed I can't get the Data Connection to work. The 3g bar doesn't even show up, and after messing with the settings trying to fix the problem I managed to do nothing. I tried using a backup I made from a week past, and encountered the same problem. Then I flashed the newest nightly and still no Data whatsoever. Wifi works fine, and 4g is acting weird but I got it to work a few times. Does this have something to do with sprint?

I think it is the same as the 4G 3G hang. I typically get it while tethering and the phone is normaly quite warm.

So I managed to fix the problem. I ended up flashing Koni's Elite Rom

I got an error that said "Error 67 registration failure"
I updated my profile and it was automatically fixed. I'm not aware you can do this on cyanogen stock rom, but I think you can dial a number that will do this for you.
After getting the 3g to work again, I flashed back to the stock cyanogen, and it is still working. So for now im good to go.

I do think is sprint and not the rom because I did a restore to warm z and was still having the same problems. Also my brother's evo was doing the same thing and he doesnt have cm7 on it.

I figured it was something to do with the profile... I restored all the way back to sense and attempted to update profile, but it doesn't seem to be doing anything. I will try that ROM and see if it does anything. Why can't they just make this easy and allow updating of vital software that allows the radios to work on WiFi or from SDcard? This is dumb.

I tried that ROM and nothing works. Not really sure what to do. I might have to restore to Sense and unroot to take it back... I really want to avoid that if at all possible.

Unrooted my phone and getting a free replacement from Sprint. Still unsure of the problem, seems to work randomly.

I also have the same problem. No 3g data, gps, and 4g is acting weird.
I also had the same registration error number 67. My question is, how do you update your profile?

[Q] HTC Desire on MIUI Loses Data Connectivity

I've rooted my Desire and it's running MIUI at the moment. This has happened before, but I've only just decided to come here. I reflashed the stock ROM (with Sense) and the issue is gone.
Basically, when I turn on the phone, it either doesn't connect to my cell network at all (no calls, text, etc.) or it takes a long time to do so. Then, when it does manage to connect, I don't get a data internet connection. When I first flash the ROM, it works fine, but then the next time I turn it on (or in the current case, I didn't even turn it off, it just happened where I lost my data connection). Has this happened to anyone else, and what could be causing this issue?
Note: I believe it also happened with CyanogenMod, but I haven't tried in a few months so I can't confirm a recent version.

What's your radio version? because that can also be the reason why it isn't connecting that well ;o

Please Help - Signal Drops + Forced Calls to voicemail

This issue seems to be all over the place, but I'm having extreme problems getting it fixed.
My GSM galaxy nexus regularly loses all signal everywhere I normally get full bars.
Also, sometimes I'll look at it WITH signal, and it enables Call forwarding and leaves that on until I go into the settings and try to disable it. (There is no option to disable it tho...it just automatically disables after it takes a minute to load call forwarding settings).
Has anyone else been having these problems and been able to fix it? I flashed new radios, roms, kernels....everything! And I just can't get the problem solved. Recently I flashed the UGLC1 radio and that worked for a couple days but now it's just as bad as it ever was.

if youre on stock just update to IMM76I thats the build just released to solve these issues
if your on a custom rom you may want to flash a kernel that has incorporated these fixes GLaDOS 1.30 for example

[Q] Data Connetion

Hello all!
I am having constant data issues all day where I go to use an app that needs it, it says that no data connection can be found or something. I turn the radio off, turn it back on and then it works. It's a good work-around but it does get very annoying. I've tried multiple 4.4.2 roms but no avail. I tried a different kernel but I couldn't even use the phone. Any ideas?

Same for me; I'm rooted now but it happened before root and after the JB ota updates. Annoying but otherwise I love this phone
I think this has been a known issue since ICS (I could be wrong though).
If anyone knows a fix that would be cool (I have GSM google play gnex)

My issues started late last night, lost data connection and it didn't come back. On my way home, it connected then lost again at home. Went to Verizon today and they couldn't figure it out, said possibly the radio is taking a crap.
On my way to work, it connects then gone. I tried flashing the radio, pulled battery, booted without sim, formatted cache and delvic. I have tried everything and think it's the end of the line for it
I've been rooted since the day I got it and had the issue once a while back but it straightened out and has been great since.

Certain CyanogenMod ROMs have trouble with the Network Modes sticking. Which carrier are you using? For my carrier, I had to have the correct APNs set to get 4G and MMS working. It might be that this is the problem in most cases, especially when the phone switches between 4G and 3G in spotty areas.
