Kinda new to all this need some advice - Galaxy S III Q&A, Help & Troubleshooting

Sup guys.
Recently been messing with my s3 after switching from an xperia pro.
Ive managed to finally get ultimarom going after some hickups from other roms.
I managed to get the null imie and 00000 serial etc. All seemed to be repaired when I flashed the mg4 baseband back to the phone.
My problem is that every now and then it looses signal. Bars on on like 3 but it has a warning triangle in notification saying no service. Even though its on 3 bar.
Could someone check this screenshot out and tell me if it all seems ok?
Im on android 4.1.2 so not sure what version of ultimarom. I wanted to update to the latest ultimarom but im worried it will mess up all my imie etc again.
Could the random no service be my signal tower or indeed the modem problem?
Thanks in advance

Once you flash a rom some will change modem and some won't. If you have no signal flash mg4 modem and you will have signal as you have found out :thumbup: as for the signal drop try a different v2 Efs modem. And yes maybe a transmitter problem you can't control

Thanks for tbe reply. When you say try a diffrent version 2 efs modem what ones are there?
I currently have a zip file with mg4 mg2 is it? And another I can choose from. All 3 give me signal but I still vet the random cutouts.
If you could maybe name the others and I will search for em. Im an xbox 360 techy lol digging into phones has been a side hobby for me haha

Anyone?

Chances are that its the transmitter mate. Ill try and fine some more modems for you but you should try going to next transmitter.

[Q] Data Issue with Phonebreaker 2.1 Rom

Hi Guys,
I recently got the SG2 on AT&T (i777) and the first day I had it stock I was getting consistent H+ connection in my house and pretty much everywhere I was going. I ran the speedtest app a couple times, and I was averaging 2.5-4 mbps downloading which wasn't too bad.
That same night I rooted the phone and flashed Phonebreaker 2.1 rom following the correct steps (Not my first time rooting/flashing roms, I've done it to my Tmobile SG2 a few times). However the following day it seems my data connection has become inconsistent and speeds have slowed down to a drag. The indicator on the phone can never stay on H+ or even H..it consistently cycles from H+ to 3G to H (tried it in same locations as the first day with the phone). I ran the speedtest a few times and my download speeds ranged from 300Kbps to 1.6mbps if I was lucky.
I tried looking around in all the forums, I re-did the APN settings found in these forums, I troubleshooted with AT&T but to no avail.
Anyone have any suggestions? Would much appreciate it as I love this ROM minus this data issue I'm having.
FYI - Stock only shows H+ even if your not actually on it.
Its an illusion AT&T does to make the user think they have great connection everywhere.
Also try flashing a different modem, that might be the issue with your speeds, cause I changed to the leak's modem upon many request.
Thanks LiLChris06!
I tried the KH7 modem which did nothing, and I tried the KK6 which seemed to improve it a bit. I went into AT&T today and they said maybe it's just a defective phone and were willing to switch it out, which I might do.
However I love this ROM so much, is it available without the custom modem you added or with a different modem in the install rather then the UCLK2 I think you included?
Thanks

Hmmmm...what you mean by is it available without the custom modem? Maybe Im reading it wrong. As you know, because you said you have tried different modems, there are many different modems you can try. Shouldn't matter what modem the ROM comes with. Think there is a modem thread around here that has some good info. I think Task also just uploaded the the new LC5 Modem
I should have worded my reply a little better, and it might come across as a newbie question but basically I was wondering if that rom came with the stock modem the i777 comes with because when I had the phone the first day stock, the data speeds were pretty reasonable (3-4 mbps/downloading).
Wasn't sure if flashing different modems other then the one that came with the phone originally would help out my issue, but I suppose it doesn't hurt to try. I did find the UCLC5 modem so I'll try that in a few minutes along with the other ones I haven't tried. If no luck, I'm going back to AT&T to exchange, probably defective phone like they said.
Thanks again for everyone's help
Sweet, found a solution!
I tried all 7 different modems under the same conditions, KJ1, KJ4 and KK6 were around the same ball park. KH7 and UCLC5 were a bit slower but close to each other, UCLC2 was by far the worst..and the winner was KJ2, big difference.
Thanks guys!

[Q] Signal Strenght Reports Wrong

Hi there.
I got this problem which has been annoying me for quite a while, where the signal strenght given in dbm, is reported wrong. It can only show 4 values:
-89dBm
-95dBm
-101dBm
-107dBm
Even when i am close to a transmitter, it gives me -89dBm, where my previous GS would show -51dBm.
I assume this is only being shown as -89 but in fact i have better signal, but is there a way to fix this?
I found some posts on xda with others having the same problem but no solutions found yet.
ROM, Kernel & Modem changes have no effect, they all show me -89.
Thanks,
Ben
Whick firmware does the phone have now? Because i don't have this problem
I have ran Slim ICS, Hydrog3n ICS and now it is on Resurrection Remix.
All roms gave the same results, the current modem is NELP2, though i have tried like 7 which gave me the same result. Also, now i am running Siyah kernel, but i have ran Fluxi, CM standard kernels etc.
My neighbour's phone which is running WIUI seems to also have the same behaviour as mine.
I'm aware this thread is old as hell. But hey there's no answer to the question, I'm having the exact same problem. Even driving to the tower I still get exactly 89dBm when my other S2 goes around 60dBm

It will be down to your modem version which has been updated at some point by a rom. Go to the modems thread (use search) and try another.

[q] big help needed.(signal issues)

I bought a sgs2 about an year ago and since the very first day I had problems with receiving calls and even making them.
If I'm sitting at one place everything's good but as soon as I move something goes very wrong and the call drops.well if I'm moving I'll be glad to even get or make a call although the signal in the notification shows full.
Now on the stock ROM,the signal strength is about -61dbm 19-20asu but on any other ROMs that I've tried it never goes beyond -89dbm 11-12 asu.
Next I read a lot about flashing different modems that might solve the problem but no.its like nothing seems to work.(BTW I tried a lot of modems for my country and others as well and used getril also to match the ril's as I read about that in forums.)
While trying go flash a modem i lost my imei and baseband.
Luckily I had a backup of the stock ROM and when I restored my phone at least I got the imei and baseband but whenever I reboot my phone for something,the problem's back.
Im on stock ics 4.0.3 with siyah kernel v4.1.5.
I'd be really very greatful if one of you millions of geniuses could help me.
If you need any further details in finding a solution I would provide it ASA I see what it is that you might want to know.
Thank you in advance.

[Q] Modem Help

I have a Samsung Galaxy SII, the i777. I have rooted it and loaded ShoStock3. I love the ROM except I'm having trouble downloading apps from Google Play. The research I have done suggests that I need a better modem. I have downloaded and flashed six different modems. Each one just as slow as the last. I'm in Salt Lake City, Utah. I know that the location can have something to do with the modem as well. Does anyone have a suggestion on which modem would work the best? Also, if you happen to know that there is a separate problem and that it's not the modem, will you please let me know? Everything else seems to load fine, it's just trying to load apps from the market that I'm really noticing it is really slow. Thank you everyone in advance.

Modems are good in different places. What's good for me might be awful for you. Have you done a speed test?
Sent from my SGH-I777 using xda app-developers app
You've already flashed 6 different modems, you should know by now which one is the best for you out of those 6.
If you don't like them all, try some more and pick out the best.
Have you tried KH7 or LL6?
Side note: why can't you use Wifi for Google Play?
You are I assume flashing modems for this device right? I only ask because obviously the i9100 modems wouldn't work for us. (And I'm pretty sure calls don't work with them) also, if you are flashing all these modems and they ARE for our device, and NONE are working properly, I would look at a fresh flash of the rom of your choice wiping everything again or going back to stock to eliminate hardware error possibility.
I did verify that they were all for my model and network. None of the six were any better than any other. I also noticed none of them worked on the 4G network. I tried to download an app to do a speed test but after 30ish minutes waiting for it to download on each modem so I could test it, I gave up.
Shoman94 changed to UCLL6 modem on his latest build. Are you using this one now?
Or you can select all the modems from here:
http://forum.xda-developers.com/showthread.php?t=1336958
They seem to be working OK, at least for me. I have tried at least half of them although I am still running ICS (CM9.1), not JB like you.

In the Settings of ur phone, since u r runnin SHOstock 3, do u have the Mobile data box checked under Data usage ? And do u have the "Set mobile data limit" box checked under Data usage (this could hinder u) ?? And under More settings/Mobile networks is the Network mode set to something Other than the "GSM/WCDMA (Auto mode)" (this could also be the problem)??

So, I un-rooted my phone but from what I understand, even doing that won't re-set my modem. It's still working slowly. My biggest fault here was not doing speed tests from the beginning and not noting down what my phone came with. If I could find what modem my phone came with, I would root and load it back on.
I really appreciate everyone's help and suggestions.
Is there anyone in Utah on the 4G version of the SII that could tell me what their modem is?

Check your APN settings, that can cause plenty of issus for data.

[Q] Can I change modem im my AT&T Note?

HI everyone... I have a question:
I have an at&t sgh i717 with a virgin sim (Im outside of the us), and I need to choose a new modem (I think) because currently I have this t989 uvle1 for tmobile that I had to use to unlock my phone. I'm getting three bars in the signal so my question is or are: do I really need to change the modem? Does the signal have to show more bars so that one can be sure that the modem fits the phone? And, a modem has to be chosen depending on your phone and on your location (since I'm in southamerica)? does having a 2.6.3 kernel affect any of this, should I upgrade it?
I hope I'm not asking too much, sorry,
thanks
Wrong forum, belongs here. I've asked mods to move your post, sit tight.
Edit - You mean i777, right ? (I717 is the AT&T Note).

Since you have an i717, normally you would probably want to flash back to an AT&T based modem. However, since you're probably not on AT&T's network, your best bet is to try several modems and see which one works best with the provider in your area. My recommendation is to at least base your tests on signal strength and speed tests.

OK, I'm going to try several because just yesterday I found out that my gps didn't work and I think that's related to not having a suitable modem.
Additionally, I performed a speed test and whereas I get 12 mbps for download in my laptop I got 10 mbps in my phone, not much of a deal though.
Regarding signal, I get from three to four bars which isn't that bad and I've made a couple of calls and everything seems to be fine.
Since the gps thing is a real setback I'll flash another modem but I'm also thinking on upgrading to ics because right know I'm on gingerbread 2.3.6 with 2.6.3 kernel so I wanted to know if It's better to flash the modem before or after upgrading.
Thank you for your answers
You will probably have better luck if you upgrade to an ICS or jelly bean based rom.

The gps not working isn't always antenna issues. You can try to update the gps data file. Go to the market and get a gps fix app. You're looking for an app that will replace your gps configuration file with an updated file.

Thanks, good to know that.. it's just that when I received the phone it was working and based on that and some comments on internet I attributed this error to the switch in modem/baseband/radio...
Anyways, I'm installing a rooted ics rom and I'll come back to comment, hopefully positive things
