Data on CM9/CM10

Anybody Know how can i get back my 4g data? I have CM10 and it was working good for about one hr and now my data is gone, any idea?

That is apparently a known problem with the CM roms on this phone. Probably the only reason I haven't flashed it yet. Sorry.

Yeah I think I'm gonna switch to Synergy ROM because all CM9/CM10 based roms has the same problem e.g Paranoid and AOKP, also I have problems sending MMS I don't know if its just me or ROM problem

I've been watching the forums for all the AOSP roms and mms seems to be a fairly consistent problem that I don't want to deal with. That and I need my camera to be fully functional for work. I swear by CyanogenMod and I am waiting patiently for a build for this phone.

I've been running cm10 since the first preview as my daily driver. There are some issues, to be sure, but I'm living with them. 4G data should be working just fine (just as good as stock, in my experience). It's 3G data is very erratic: sometimes it'll cut out altogether and sometimes it'll fluctuate wildly between zero bars and full bars (or from -100 to -250db). This is a known issue regarding the RIL and will hopefully get fixed sooner than later.
MMS is also a know issue. You should be able to receive MMS, but sending MMS only works once after installing the rom. Once you reboot, it no longer works.
The camera is now working just fine (stills and videos), though there may still be a hiccup or two. I use the camera for Facebook, Foursquare, etc without issue now on cm10.
Other than that, the rom is very solid. Jellybean is silky smooth, Google Now & Voice Search is working good (though after a reboot I have to make a phone call to get voice search to work again). GPS is absolutely quick to lock on and without issue. The statusbar is much more clean on cm10 (jellybean) than on stock Touchwiz (cluttered mess with unnecessary icons).
Anyway, back to your issue with data. If you're not getting any data whatsoever, either you did something wrong or you need to do a fix. You can try the Phone Info app from the play store and select LTE/CMDA, which will usually fix the no data problem. You need to be careful though because you don't want to lose your IMEI (although there seems to be a fix now).

Download phone info from the market and select cdma/lte, 4g fixed

I've been doing that and it works for few time and again it drops the 4g then I just get 1x icon or anything .
I would like to use cm10 is pretty good and smooth but I have too much problems with my 4G everything else works good.

Do all AOSP rom's have data issues?

I keep reading about data drops, 3g/4g issues on most of the Aosp roms like CM10, AOKP etc. Since we don't have the right RIL for our phones yet, is this a common problem?

You are going to continue to see data issues with jb based roms until either a) vzw releases tw jb stock rom or b) the current RIL gets improved. But yes, its an aosp jb issue.

data working fine on paranoid android build 9/6.

Try going in low coverage areas, it will drop. At work, whenever I am using an AOSP rom coverage keeps on dropping but when I am on ICS, it never drops.

Actually I have the same issue on the stock phone. It drops data in low signal areas.

no it dont...it does work fine in good coverage areas, but when you get into low signal areas the data handoff 1x/3g/LTE is terrible.

nothing like aosp does...when im in town i run paranoid android, but when im heading out of town i revert to my beans nandroid. i do love pa tho, its a solid rom.

I can deal with it on AOSP cause if far better then my galaxy nexus was with data drops lol

I am on liquid and I have much better reception. I work on the 18th floor and I used to drop all the time on touchwiz. Now my data is very stable. However I'm sure it varies depending on the phone. I had data issues on touchwiz, and this is noticeably better.

Supposedly there has been a fix in the last day or so. Some of the AOKP builds have them merged in from yesterday and today. I believe the CM was the ones who fixed it but not sure if they merged it in their Rom yet.

More info on this? Is it in liquid rc3?
The issue is strictly with handoffs and 3g reception, 4g should be just as strong as stock.
Also what are the chances of ever getting up to stock quality with the ril if we hypothetically never got the jb update. Just curious as to if we're going to be in this situation again next time a new version of android is released.

Liquids Rom was released before the fix. Lookhere for info and you can download the build in that thread. Other AOKP threads there are starting to add it in as well our have a flashable zip for it.

Aosp Data Problem
I have a similar problem with aosp roms.I flashed pa 2.18, and 2.17 yesterday and after initial install 4g was strong, and then i tried to switch to phablet mode and upon reboot i have no data at all. Same thing happened with aokp build 4. My imei is still there and my phone number as well, but no data what so ever. Just wondering am i doing something wrong?

I've been on CM10 Nightlies for the last month. Running CM10 M2 now.
4g reception is strong (no drops that I've noticed). In earlier Nightlies 3g used to drop every couple minutes, but with the newer ones it now stays up. However, 3g reception is still weaker than stock.
Fortunately it doesn't affect me too much. 99 percent of the time I'm in either a strong 3g or strong 4g area.

Poor Signal Strength with Cyanogen 10 & 10.1

I live and work in an area that has poor signal for Verizon. I almost immediately flashed to CM 10 after I got the Verizon Galaxy S3 because I was running CM 10 on my previous Sprint Galaxy S3 without issue. I have been updating the radio and RPM with each leak (currently running K3) and things got a little better but I constantly dropped calls. I had to flash back to stock because I flashed to CM 10.1 and my radio got messed up. I ran the newest stock rom for the last week and noticed a huge difference. I still had low signal but my data dropped less frequently and I could actually make phone calls in areas I couldn't before.
I rooted, and flashed to CM 10.1 and noticed right away the signal is not where it should be. I can't make phone calls inside of buildings with low signal at all, where with stock I could without issue. I love CyanogenMod but I don't think I can deal with the poor signal.
Any ideas on what could be causing this problem and maybe a possible resolution?

Depends on where ya live, your mileage may vary. I get within 1-2 -dBm between the two.
Technically since we don't have the source code the reason CM10 has data is by a work around.
There really is nothing you can do. It is what it is. I've run devices with CM that have provided better signal, and usually were on sprint lol and then run them where they provide the same or slightly worse quality.
Happens.

This does not ha e anything to do with cm 10. This this to do with the the phone radio. This is the reason why I switched to the DNA now I have Full bars everywhere I go. On my s3 I used to drop calls all the time.

Ok I really hope I'm not beating the dead horse here but I have a similar problem on my verizon Galaxy s3 and I was hoping there might be a fix

My understanding is that the CM developers dont have the GS3 source for something (the RIL?) so they have to use a different RIL? I'm probably totally butchering that, because I dont understand the words I'm using, but from what I've gathered the signal is what it is on CM, and will not improve beyond where it is.
It is certainly usable for me, but there are many times my wife has 4g and I have 3g, or she has a 3g signal and I have nothing at all (she has a stock vzw gs3).

I think you're correct on the RIL part.
I had the same issue on 10.1. I switched to an older radio, and though it is not perfect, it did give me better reception and the switch from 3g to 4g is faster. My radio is VRLHE

Why not try a rom like beans. It is a touch wiz rom that looks like aosp and had a lot of aosp features. That way the radios will work fine you will still have aosp stuff and all the goodness of being rooted.
Sent from my SCH-I535 using xda premium

Let's not get confused here. Tw rom's like beans are themed to look slightly aosp, but are far from it. Aosp has so many customization options that tw cannot come close to. (I'm an aosp guy, if you can't tell). That being said, signal strength will always be an issue on aosp based roms due to the Samsung ril only being licensed to samsung, hence only working on tw rom's. The official ril code will almost never be released as its how qualcom makes its money. Currently aosp rom's use a work around home brewed ril that is very effective, but not quite what stock rom will offer. So if your signal is poor where you are, aosp may not be the best choice for you, but for most the signal is just as good as tw, and imo the only way to run android.

I'm not confused, that's why I said looks like (aka themed like). Also I said some aosp features like MMS, camera/gallery, lock screen to name a few. Its no where near the same but if they are having issues which I read a few people do have with signal and losing data its a nice alternative and has SOME similar features.

[Q] Signal issues with AOSP roms

i really want to stay with a AOSP rom (CM 10.2 or Illusion 4.3) but when i go to a AOSP rom i get reall bad signal (1 bar or nothing) living in chicago on verizon. When i go with a TW rom using 4.1.2 the signal is great. currently i'm using Hyperdrive RLS15 and the signal is great get 4 or 5 bars. has any one else had similar issues?

I never had that drastic of signal issues. At my house I get poor reception. (2bars max). On TW I get 2bars. On AOSP I was only getting 1. I recently flashed Latest cm10.1.3 RC2 and my signal issues have greatly increased over prior builds.
Just my 2¢
Also. I know the new AOSP ROMs require the new baseband MF1. Are you updated?

I get very bag signal at my work. I just switched to an aosp rom and I can actually send texts better than before. Instead of failing 8x, it only fails 2x. I'll take it though.

On the 4.3 based roms there still may be some legitimate signal /data issues.
On 4.2.2 aosp ROMs the issue is mostly cosmetic, you have the same signal, but the ROM show you less bars.
Check out signal in phone status before assuming you are getting worse signal.
There are still some issues with data handoffs in aosp, but it isn't as bad as it once had been.
Sent from my SCH-I535 using xda app-developers app

Yes I'm using the latest MF1 firmware. I even reflashed the firmware and all getting bad signal with and AOSP roms. Is the something I need to do with the radio or kernel. I tried a few kernels and still same issue.
Sent from my SCH-I535 using xda app-developers app

So far every new version of AOSP has had signal problems at the very beginning. Due to that fact I usually wait until the problem fixed.

I'm on Masta's unofficial CM 10.2, and my signal is all around better than my old TW ROM (Hyperdrive RLS 14/15)
If you're responding to me, make sure to quote me so I get an immediate email.

OK so I just had access to my gf's phone. I'm running PA, she's on stock tw rooted. I had both phone side by side. Both phones read the same dmb and asu. Her phone had 3 bars mine had 1. I think its safe to say that Aosp Roms just display signal different.

status
Just an update i went to Illusion's 4.2.2 and the signal is OK, i don't get drop call like i was getting when trying a 4.3 rom. so i'm going to stay with this until they get the 4.3 bugs ironed out. It just freaks me out to see only 1 bar for signal.
do any of you guys of which rom is the closest to making the GS3 to look like a GS4?

[Q] Flashable Modems ?

Hey there
I've been trying around with TW and AOSP ROMs and experienced some sort of problem.
Since the AOSP ROMs definitely have a better charging time I'm willing to stick to them.
But with the current PAC ROM I have very poor signal. Whereas the TW ROM gives an excellent signal strength.
My idea was it to flash a modem from a touchwiz ROM to the PAC ROM.
Possible? Insane?
Are there any flashable modems?
Or how could I solve my problem?
Cheers

Very rarely does Samsung update the modems in our devices (it's an Intel USB-connected external modem), and the one I have in my device (running the latest stock FW of XXCMI2) goes all the way back to XXCLL1 (i.e., dates from last year):
Code:
6f5bfdff604401a05cf5f73e3edb4f2e ./N8000XXCMG2_N8000RBTCMG2_1287589_REV00/modem.bin
6f5bfdff604401a05cf5f73e3edb4f2e ./N8000XXCMF1_N8000OXXCMF1_N8000XXCLL1_HOME/modem.bin
6f5bfdff604401a05cf5f73e3edb4f2e ./N8000XXCMI2_N8000OXACMI2_1388206_REV00/modem.bin
That being said, I'll bet that any signal-strength differences you're seeing are only cosmetic (i.e., how the bars are calibrated). To prove this, go into "Settings->About Device->Status" in both ROMs while in the same spot and I'll almost guarantee the -dBm values are within 2-3 points of one another.

You gotta be right, because after another flash of the PAC ROM the signal issue seems to be gone. Weird tough :-$
But nonetheless I appreciate your help!
Must have been some weird internal file management issue...
