[Q] 4G LTE issues with CleanRom 5.0 - Verizon Samsung Galaxy S III

Hi all,
i have some questions about CleanRom 5.0 however i don't have the authority to post in it's forum, so i'm hoping someone can help me out here.
overall the rom is incredible, my only issue is the speed of my 4g lte network. it is much slower than what i am used to.
using speed test i consistently get about 12mbps down and 8mbps up, however if i go back to my stock nandroid backup so my phone is like it was before i went to cleanrom i used to consistently get about 23mbps down and 16mbps up. is this normal for cleanrom and if not is there a way to fix it because now the speed is about half of what it used to be.
i should probably also mention that i flashed the new radio and rpm that scrosler provided links to in the second post of the cleanrom forum

I've seen it stated many times that roms won't affect connection. Likely it is the new radio you flashed. You can always try flashing the old radio and rpm. Someone with s little more experience may have more insight.

Gotta agree with this. Roms do not change/impact your signal.
OP, flash another set of modem/rpm or even return to what you used before. Personally, my data speeds were below what I'm used to when using the latest modem/rom. My experience is nothing more than anecdotal and a single trial. I switched back to a prior modem/rpm combo and have enjoyed my normal speeds/LTE access.

Thank you both very much for the responses. I will try flashing the old modem and rpm to see if that solves the issue.

[Q] ICS Radios.. Which is working best for you?

Hey, I've been reading around the forums and it seems there are 3 main radio's to choose from. I plan on testing them all in depth. It seems results vary from phone to phone especially with the UCLC5 Modem (from the Note). I was wondering if other users would post their results I'm curious to how your phones are handling these modems and what your opinion on them are.
UCLA4 (from the original leak)- I started with this one. I felt like my speeds and signal didn't reflect what my bars indicated. It felt like it said I had more than what I had. I don't recall my speeds but I intend to test this radio more in depth tomorrow.
UCLC5 (modem from the Note)-The note radio is what I have been using since it was posted here. While my radio seems to show less bars I tend to get better signal. 2-4 megs down and 1-2 megs up on HSPA+. I have yet to have noticed anything strange with it.
UCLD2 (from the 2nd leak)-I haven't gotten to test this radio yet since I've had connectivity issues all day.
I think these are all the ICS modems. feel free to post any I missed.
essential I'm trying to get a general idea on the modem with the best speed.
Personally I think the new UCLD2 radio is much improved.

Newest leak is working the best for me so far. Signal looks weaker in the notification bar but my connection is much more solid than it used to be.

I agree with shepherd the latest leak works the best.
Sent from my SAMSUNG-SGH-I727 using Tapatalk 2
the best thing for everyone to do is to try them all yourself. I think everyone's phone reacts the the modems differently. A modem that kicks ass for me may suck ballz for you. Also once I flash a radio I always use it for a day or two before making any judgements as to whether its an improvement or not.
Edit: forgot to mention that my decive picks up wifi signal better as well. Not sure if that's even a modem thing or something else Sammy changed in the latest ics leak but I sure do like it

I post this allover skyrocket forum, but i notice and some others too : if you on WiFi UCLA4 and UCLD2 radio seems to be in download mode all the time. I did not try UCLC5 from Note so i don't know if this one have same problem.
You should add another modem.

Maybe it is good radio but do not connect to lte network on At&t
Using the UCLD 2 radio released with Sean's Sky ICS 4.2 rom. SO far so good. Not LTE coverage in my area but 4g speeds seem okay.

Ha, and I'm looking at now. I'm assuming many have moved on from Skyrocket (I unfortunately destroyed my HOX), but any update on radios for this device?

[Q] Will a different radio fix this?

Hi everyone, I'm running CM10.0.0 Skyrocket with UCLD2 modem. I live in Jupiter, FL and when I am traveling through town and pass through areas that switch between HSPA, 3G, and 4G, I often have to toggle airplane mode to get data back. Is this due to my radio? I was doing research in the forum about the various radios and I couldn't find a definitive comparison of the various modems to each other with a chronology of release. I'd guess that newer modems are better, but then I read that sometimes that's not the case. Anyone care to weigh in on why I lose data connection when traveling through different data zones? btw i checked my APN settings and theyre fine.
I too run into the same issue but when I'm at work I know that if you running jb data loss has been known to be an issue with it yes the newer the modem can potentially fix or issue depending on situation best option is test

Sent from my SAMSUNG-SGH-I727 using xda app-developers app
Just an update, things still seem good with CI3 compared to my old radio. Only thing I notice is it doesn't really like 4G data, it'll say 4G and have good bars, and I can make and receive calls fine. But if I go online it'll stall, and I'll watch it struggle and then swap to H+ and be fine. That’s the only remaining quirk. Not sure why it's doing that.

I know no one is following this post at this point but I thought I'd post a final update about how i resolved the last issue I mentioned in the post above, just in case someone else has this same issue and searches the forum later.
I fixed my reception with 4G accidentally, i flashed the Lightning Zap v3 kernel to improve battery and lo and behold, reception hand off is fixed!!

Radio Troubles...

Lately the radio on my skyrocket started acting really funny and with no real cause. At first it would only do 3g. And then it would alternate every 10 seconds between 3g and edge, but never 4g.
Now it will not do any data of any kind. Can make calls but its slow to connect.
Tried different ROMs and several different radios. Also tried a new sim card. I'm starting to think its hardware related. I hope one of you good people can tell me its not.
Any thoughts?
Hope I'm posting in correct thread. Thanks

Well never mind. Thanks for looking.
Flashed back to the stock firmware using cwm and all is good now( even though its stock).
But now that its working do you think it would be wise to flash back to cm10.
Has this ever happened to anyone before?
This has never happened to me before. Maybe its an lte thing.
Sent from my SAMSUNG-SGH-T989 using xda app-developers app
Your phone seems very confused as your post says T989 but you said lte. What phone do you have, what radio were you using and what cm build did you flash?
My bad...my brother has the skyrocket. I have a very problem free Hercules.
The skyrocket was on cm10 oct11 nightly. Was working fine for a month before problem started.
kernel and radio were both from cm10.
Then tried a post oct14 build of cm10 with flapjaxx kernel and the latest leaked radio, but the same thing.... no data at all.
Then flashed to stock firmware, but kept cwm as recovery. This fixed the problem completely(yeah) for about 4 days, and just this morning the radio died. No data, no cellular calls.
Weird thing is radio works for about 30 secs after a reboot. During that 30 secs I can make calls but no data.
Thanks for looking.

TMO radio data sucks.

Hello I've been trying to find a answer to my problem for a while, but can't seem to find any help. So to start off I unlocked my s2 I've flashed 3 different roms and a few different T-Mobile radios, but my data is very poor sometimes it works sometimes not it constantly drops if anyone can offer some advice I'd really appreciate it.
As of now my sgh-i727 is unlocked running on cm10 superlite and the telus radio.
Sry if this has been answered b4 I'm new to the dirrent radios

It probably also depends on your location, too. In the Bay Area and LA, SlimBean w/ a Blaze (LB7) radio has worked just fine for me.
Thanks. I've read over that post a few times. I was using blaze lb7 for a bit but then I started to test others once the data drops and very poor speeds occurred. Also I live in MS I generally have great reception.

I'm lucky to get a 1meg down and up when it actually holds the data signal. I'm actually on straight talk but with the ST tmo sim as my back up phone is the LG g2x. Maybe I didn't flash correctly, but I have tried flashing multiple times and no which radio or rom combo its the result slow speeds and constant drops. Another note my g2x fantastic in my area in ST

One little update I have noticed that my data switches a lot between E/3g/H+ data still works but I have noticed its draining the battery rather quick. My g2x does not show these symptoms my signal stays strong in my house with it.

baseband help

is there a way to reset the baseband? i wanted to try the "Jedi Mind trick SGSIII Style V2 rom" and flashed the baseband modem update that was in that thread. tried the rom a bit, then restored my previous rom that i was using prior before the jedi mind trick rom. and went to about phone in settings and saw that my "baseband version" was unknown. and i been receiving texts late. is there a way to fix this?
http://forum.xda-developers.com/showthread.php?t=1895400
You can find the blaze baseband here, I'm using the newest T989 and signal seems better.
If you lose signal after flashing the radio you want a reboot usually helps or you may have to get the correct APN.

Did you flash T989 modem on your Blaze 4G? And if you did, any issues? I checked the post and it also listed modem for the Blaze 4G which is UVMB1.
nope, no issues. its all gravy

hows that 989d telus modem running for you? I am guessing that the reason the other modem software is working is cause the hardware is similar or same between some of these phones right? is there a way to find out what chip sets are on these phones to get an Idea of what other firmware works on some of these phones? the T989UVMC6 seems to help my charge time a little and dose seem a little faster on download speeds but still nervous about causing any long term problems but there is no signs of overheating or running flaky so I guess it should be fine.
thanks
I have done some preliminary testing with the UVMB1 and UVMC6 radios and have some very definitive results. There's a speedtest.net server where I live so there shouldn't be too much variance here. I have done some other testing with the other radio (the t989d) with mixed results. The t989d radio is very inconsistent where I live.
The UVMB1 is the first three results, and the UVMC6 is the next three. Pretty conclusive to me. I will be on the UVMC6 from here on
I'm also using the UVMC6 and it does seem to give me a stronger signal. I should probably run a test and get some "official" results.
Sent from my SAMSUNG-SGH-T769 using xda premium
been running all day with UVMC6 almost 14 hours and still 64% battery and I used my phone a lot today listening to Pandora radio for almost an hour and 4 or 5 phone calls and played on the web a little. I think I am safe to say it improved battery but I rarely loose much signal in KCMO so I cant say that signal is better but I may have seen more H+ than I normally see. my home has steel siding so I dont see as much H+ when inside but it seems to have been H+ most of the time I checked today.
and again thanks for sharing with the rest of us on this information, it has improved the quality of my phone so many thanks
Welcome, I found it when had my skyrocket and figured I'd try it out. It does seem to make signal stronger and battery. The 989D was ok just didn't hold signal to long
