There is a new baseband kernel. Its the (K1) kernel. Its in scrolsers ROMS and pretty much on every touchwiz d2vzw ROM.

^This is clean ROM 5.0! And its the ROM to have.

Baseband updates certainly do affect signal. It seems that the stock one works best for you.
The good news is you don't need to update baseband to go to a different ROM. You can keep your stock radio and flash a new jellybean leak without altering your signal.

I've also noticed that many ROMs have roaming disabled by default. Not sure if it makes a difference, but might help.

Sorry to start another thread about this but i've looked and searched.. I flashed Android Revolution HD last week, and I've only have been able to get 3g on my status bar since. I've tried flashing different roms to no avail. I did a quick speedtest and got 1.4 down 1.2 up. If I remember correctly you have to flash back to completely unrooted stock. ?? is this the only way ?
Maybe if you flashed a new radio it would fix it.
I tried it before and it didn't work but I just tried it again through bootloader and it's back.. weird.. 3.0 down and 1 up Thanks
Any help with this, stayed on hspa for a bit then switched to 3g.. do i have to go back to stock then re-root? Thanks in advance.

I've noticed that sometimes my connection will be 3G, then switch to H once a data session starts (many other users have reported this also, regardless of the ROM being used). Is this the case with you? I assume you normally have HSDPA (or HSPA+)? If your speeds aren't affected, I wouldn't mess with anything. If so, try and reflash the radio, as the OP tried. Give it 20 minutes or so before testing again.
No I completely lost hspa, I think my speeds dropped. Tried flashing a new radio a couple of times, tried everything. I was on 3g for a month or so. RUU'd back to stock, now its fine. Thanks though.

I haven't found any answers on this, but once or twice per day my phone will be stuck on Searching for Service even though in the status bar, it shows like 3 bars of 3G or 4G. Data still seems to work, but this seriously drains the battery. I'm on stock unrooted HD. Any advice is appreciated. I already tried a new SIM. I bought this phone here on xda, no box, so I doubt Verizon would let me exchange it.
I know this is a silly question but what radio is installed?

VRLG7 is a downgrade in release but does not hurt to reflash any of the modems to see if it fixes problem and which works better for your area. Affects 3G more than it does 4G..

Maybe root it and try a custom kernel, though I'm not positive that will help. Possibly a total wipe and reinstall of a stock system? If you bought it from someone here on xda, chances are it has seen some mods. Hopefully someone with more knowledge on the subject will chime in for ya. I just hope you didnt buy someone else's problem... :-\

I got it and it had never been rooted before. I rooted it, used custom ROMs, they all weren't my cup of tea, so I unrooted and flashed the stock HD images via ODIN yesterday. I just flashed the HE radio, and it seems to at least be a bit better. I'll keep experimenting.
It's still dropping signal. Sounds like I'll be calling up Verizon tonight.

Uhh.. yeah don't dial *228 on a 4g phone. It could fry your SIM.
Well I did it and a samsung dialog box popped up and said, "HELLL NOOO. A SIM card does all dis crap."
So, right now I'm on unrooted stock HE, and while the problem seems to be less of an issue, it's still there. Any other suggestions?
So I did a full clean wipe, twice just to be sure.
Flashed RC1 and everything seemed to be going great at first. Then I noticed that the signal is dropping in and out. (I live in San Diego) It won't hold a signal for any reasonable amount of time. So it drops from 4G LTE going off. I've rebooted. At a bit of a loss. I'm operating on ATT.
Should I try to reflash? I was previously running CM 10.0 with no serious issues.
I've made sure the priority is LTE/GSM
Any help would be greatly appreciated!
May be your APN? What radio are you using?

Same happened to me. Reflashed the modem problem fixed.
Sent from my SAMSUNG-SGH-I727 using xda app-developers app
I had it on ATT Phone and then switched it to ATT LTE. Issue wasn't resolved. I tried the other APNs as well. Same result.
For poops and giggles I flashed the most recent nightly 05/06 and still had the same issue.
May seem silly to ask, but how do you flash the modem? That sounds like it could be a solution.
Edit: Ermm what radios did you flash to fix the problem?
Looking more like you need the latest UCMC1 radio. Happened with a big kernel update in the nightlies, since this is getting closer to stable, I'm sure we'll see this problem more as more people start updating.

Yea, I flashed that one after I found it on a post about the radios. It fixed the problem to an extent. However I'm getting much weaker signal than usual (although this could be the bars not displaying properly maybe, I don't want to jump immediately to a conclusion) and also am getting the data bars greyed out which means it's not.
Do you recommend reflashing the radio again?

b2tracken,
Just wanted to say thanks for your post here and that I'm experiencing the same exact thing. Yesterday I upgraded my skyrocket from an old ICS install to the latest 4.2.2 with CM 10.1, coincidentally right when this RC1 came out, so I quickly upgraded from M3 to RC1 last night. This morning I noticed that something was up with the radio and read your post. I flashed the radio to UCMC1 like you probably did and now I'm getting a connection, but about half as strong (in bars) as before the whole upgrade. Really no complaints yet - it hasn't hindered phone calls or mobile data connection - but I would be interested to find out if there is anything I can do to improve it, or configure it properly. I'm a big noob when it comes to phones.
Thanks,
Chad

The only other thing that I have changed is going and changing the APN under mobile networks to ATT LTE from ATT Phone. I'm getting about half signal also and intermittent issues with it greying out. (They seem to have not been very prevalent.) Seems that I'm not the only one with the issue which is fortunate. Give that a shot. Hopefully it gets worked out in the next release.
Att ucmc1 apn
SO I've uploaded the original UCMC1 stock ATT APN, you can just create a new APN and set it like these images.
Also wondering, after you cleanup (format data, system, cache, dalvik cache), No reboots, you do the next in the following order:
1-flash UCMC1 Radio
2-flash CM10.1 ROM (I'm still on 04/23 and everything works: http://forum.xda-developers.com/showthread.php?t=2272261)
3-flash gapps from 20130301 (http://goo.im/gapps)
Good luck,
Don't forget to hit THANKS if I helped you
Having the same exact issue, I've done everything stated here, only thing i did differently was updated the radio after CM.
Well the problem came back randomly with RC2 to an extent.
Now everything is showed as greyed out and no connection available including wifi.
Anybody have a clue on this?

+1. UCMC1 should be used on all current CM10.1 builds. Any older radios will cause major problems with the newer JB-based blobs we use in CM10.1 past around 4/24.
One caveat: I don't know about Rogers users, sorry guys. If you have an official JB release from Samsung, you should use that radio. (Otherwise you will have to use UCMC1)

What nightly are you on? Anything after 4/23 (including the RC's) will have a lot of those instability issues. The developers are working hard to fix it if you want to read the development thread.

This worked for me, but it took a few tries. The first couple times gps got screwed up. I ended up doing a factory reset, then odin flashed back to mb1 (unrooting) .

You might also consider some of the custom TW ROMS that have all the OTA has to offer and more with better stability. Synergy, Hyperdrive and MOAR come to mind, but there are others as well in the development section.

Can anyone please tell me whether CM-based ROMs like Carbon automatically update your baseband modem? I'm currently running the 5/15 nightly with ML1 modem and am wondering if I need to update my modem? Yesterday my radio system started acting really odd - my data connection completely dropped out for about an hour. When it came back I could only get 1x or 3G connections, but no 4GLTE. I am pretty sure it isn't location related, I generally get a good connection in the city (Portland, OR). All getting slow connection. Any suggestions would be greatly appreciated. Thanks in advance.

ROMs do not change or update your baseband unless you are flashing a full ODIN image or taking an OTA. Modems have to be changed or updated separately and by you when you flash ROMs.
Different modems perform at different levels depending on the individual device and area where you live. Best thing to do is flash different modems, try each one for a few days, and test which one works best for you.
