[Q] Cyanogenmod 10.1 RC1 Data Connection Issue - AT&T Samsung Galaxy S II Skyrocket SGH-I727

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.

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)

It seems no matter what I have issues. Now I'm having more issues with RRs and general crashes that force me to clear completely. I updated the radios but still had issues after. Almost thinking going back to square 1 and rerooting etc etc.

You said re-root. You don't need root to flash roms.
And probably not, cm is all busted right now anyways and data drops, reboots and all the other stuff is gonna happen regardless.

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.

Lost "H", only showing 3G

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.

cannot get 4g at all

I'm running the latest Cyanogen and cannot get 4g to save my life. I tried the *#*#info#*#* settings but nothing. I don't have the cdma+lte option like she does tho. I changed my ROM and wiped but nothing. My wifes stock TV gets 4g fine but i'm stuck in 3g
Any help?
sometimes on cm and aosp roms, instead of lte, it would be listed as other. usually a soft reset would get 4g back though. Might want to try the stock rom, rooted and see if you are still having troubles. Your sim might be on the fritz.

Thanks guys. I'm downloading a stock ROM now, but how do I tell the radio? I believe its MR 2.5 but I forget. 4g worked before, but doesn't now. Not sure what I did. Under info I don't have other, but I've unknown. Still doesn't work with that.
Eh, bad stock ROM I came across, but I installed liquid now I've 4g. So could it be just a cm problem?
Double post.

What portion of the "hack" affects the reception

Rooting, ROMS, Kernels, Basebands, MODs, So many flashing options. I lost my reception at my cottage which is on an extended network roaming. As soon as I go into that area everything drops, voice and data. I Odined back to Stock unrooted did a factory reset and the service returned flawlessly.
I was on latest baseband J1 at the time, SynergyROM, MIEA backed up, bootloader unlocked.
Now I'm getting itchy fingers again. Want to go back to Synergy, etc. But I DON'T want to loose my reception while I'm at the cottage for a few days. It's my only connection to the world.
Starting from scratch again, what could've been the culprit?

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.

CleanROM recommended add-ons, what are they?

Recommend add-ons by Beanstown106
I535VRBMB1 Modem can be found HERE!
I535VRBMB1 RPM can be found HERE!
^^^ What are these? They're the "recommended add-ons" by JellyBeans at the bottom of the CleanROM post. Anyone know what these are. Is this a radio and something else?
Just curious, if I should flash these or not.
newest modem & radio/
flash them in ^this order////
The VRBMB1 modem and rpm were included Verizon's OTA update from 4.1.1 to 4.1.2. From what I've read, most people have experienced better data reception after flashing these, but some think it made things worse. I've flashed them and don't notice any difference in data, but possibly better GPS reception.

You should. If you go into Settings / About Phone, and the Baseband version (I think that's the modem) should say I535VRBMB1.

The ROM that I am using currently is Octane 2.3.6 for T959V, but all ROMs for that phone work on mine. 4G Only works on a few ROMs that I installed, but they aren't Deodexed (which i need).

If it says "H" next to the signal bar, you're using "4G". The stock Samsung ROM uses 4G instead of showing H, all other ROMs show H.

There isn't an H either. I think the problem is that the ROM has support for only T-Mobile, but I'm just looking that there is a way i could get 4G with Wind.

There doesn't seem to be a flashable zip for 2.3.6 but if you update to anything newer than ICS you'll be able to flash it.
I actually recommend you give CM11 a go. 2.3.6 is now 2 years old and your phone is vulnerable to a lot of exploits that Samsung never patched but are fixed with more recent ROMs. KitKat runs amazingly well on this phone and you won't have the bloat that the stock Samsung rom comes with too.

Check out the CM11 thread, there haven't been complaints about the ROM. There was an issue with a Google Play Services update causing some battery drain, but I released an update a few days ago that had a patch fixing that.

I got 4G working by wiping everything, and installing the rom again. Then I installed gapps and 4G wont work. I did all of that again but didnt install gapps and it works great! :good: The ROM is actually very good for this phone and I will probably keep it like this.
But I still need the gapps for automatic updates, and very easily downloading apps. Mobogenie just doesnt do it for me.
And Candy Crush wont work as when i launch it, it stays at the loading screen then just closes to the home screen.
Any way to fix these issues?
