Hello fellow XDAers,
after switching over to my dads old SGS2 (i9100) i'm having nothing but problems. I'm in germany and use a O2 prepaid reseller for phone and mobile internet. I'm a happy user of CM ... have been, anyways. After a while of use (~2 months) somehow mobile data would be unavailable after leaving WiFi. After a while and trying virtually every fix proposed on
code.google.com/p/android/issues/detail?id=40514
i started thinking "uh, maybe my old modem firmware isn't quite the best idea ... after all, many users report that new modems both fixed that problem AND increased battery life and mobile data performance".
This is where
all
started
going
down.
I've since tried many Roms, including the ages old official samsung one, and every 2nd or so CM since CM9.0. I've tried many Modems, including the ones reviewt on
eric10234.wordpress.com/2012/07/13/samsung-galaxy-sii-i9100-which-modem-is-best-part-4/
As well as the "good" ones such as BVLP*, XXLP6, XXLQ6, NELP2, NELP4. Each on many Roms. I've tried each Modem with the stockroms RIL, the CM versions RIL, as well as the "correct" RIL obtained by the GetRIL app.
NONE OF THEM WORKED. Some worked better ... whereas better means "sometimes a connection ... maybe even phonecalls for 30 seconds", whereas worse means a 40°C Cellphone after 5min and not even a signal indicator in the Statusbar... yay.
Now i'm kind of lost. I don't know what else to try -- especially if even the stock roms fail. I somehow have the feeling that this is not hardware or carrier related, so i still suspect this to be some kind of software ****up.
Please help me getting this straight again ;(. Thanks in Advance / for reading. Best Regards
- Dario Ernst
*EDIT: I've also dumped a radio log of my current combination (UNKNOWN RIL, BVLP6 Modem, CM10.2-NIGHTLY): tmp.kanojo.de/radio.log ... unfortunately its not very informative to me ... except ~something~ goes wrong.

I must admit that i haven't. However, i somehow fail to understand how not doing this could lead to my problems. The modem firmwares and RILs are ~5 files which, as far as i understand and can try to verify using strace, ltrace and gdb, do neither read any config files, nor read additional binaries or libraries.
That said, i'll still try making a titanium + CWM backup, backup those on my computer, and try this and reflashing a current CM. Lets see whether that helps.
Thanks for the pointer, i haven't stumbled upon that script collection yet .

Have you tried getRIL to verify and ensure you have the RIL? Find it also on google play :good:
Still - if you have been flashing different roms and never done a thorough clean I recommend you do!

With each iteration of flashing a certain Modem on a certain ROM, i've tried both, the defaul RIL that came with that ROM as well as the matching RIL that GetRIL suggested for this modem. It usually made things worse for me though -- sometimes as bad as bootloops ;/.

Well, depends on what a thorough clean is. I always format /system, format /data, format /cache before i flash a ROM. I then restore the apps + datas backup i've made with titanium.
To be on the safe side, however, i'm going to take a few hours to tinker around with those wipescripts JimSilver posted before...
Thanks for your help! I'll report back .

Heyyas Everyone,
soooo, after a few days of use i must say ... i do not understand why this works! NOT AT ALL! I've left the BVLP7 Modem that i had, and used the RomNuker/RomWiper Scripts, then reflashed CM stable, restored all my stuff with Titanium and ... IT WORKS! I get very good reception almost everywhere, and Mobile Data is available directly after leaving WiFi, with only minimal noticable handover time. PERFECT!
THANK YOU GUYS!!!111oneoneone
The only thing thats left now is that the modem seems to drain battery *quite* heavily. No matter what resource intensive applications i use, not even 3D OpenGLES Games get the cellphone warm. One 250kb/s download and the thing is BOILING. Also it tends to eat up lots of battery when there is no signal. That was way better before, but i'll start digging around and searching for a fix.
Again, i wouldn't have thought that something so simple makes such a difference! THANKS!
Best Regards

Im very new to all of this but also very interested. Iv been reading allot of your posts but there still are a few things that im not grasping. If anyone can sum up one or all of these questions, it would help allot.
I just rooted my TB and have been flashing a few different ROMS(BAMF, Vanilla, and one other i cant think of) but on all 3 ROMS, my GPS will not work and my google calendar will not sync. Is this normal? I flashed plainjanev1 and it seemed to solve most of my problems, but its just like the stock and the whole reason i wanted to root was the possibility of changing my phone without losing GPS, Calendars, ect.. Does rooting and flashing a ROM usually mean i can lose things like GPS and Calendar?
Also, im lost on the concept of kernels and radio. Is a kernel something i can download to fix a problem i am having with my phone such as no GPS signal? And is a new radio download something that will help me better connect to my phone service?
I have many more questions, but dont want to bore you guys too much. Still reading through posts and trying to learn. i respect all of you that know this so well.
Thanks.
When you change ROMs, make sure you WIPE so that the new ROM gets a clean slate.

You should probably wipe your caches and even reset your user data when flashing a ROM. A backup app makes this a lot less of a pita than it sounds.

I'll give this a shot but there are much more complete and better explanation than I am capable of.
The kernel sits between apps and physical hardware and manages the system resources.
The radio is firmware for the LTE, CDMA, etc. hardware in the phone.
The pic shows a basic outline of a kernel.

So basically, a kernel is the driver that help run the OS. And if i flash a new kernel, it will have a direct effect on how my OS operates.

basically. kernels are most often used to affect the way your cpu is utilized, affecting things like speed and battery life. they will not affect things like gps and calendars. those are caused by not wiping data. the easiest way to do this is to install the rom with rom manager. when you do it gives you the option to wipe data and cache, as well as make a complete backup of everything on your phone (including apps, data, homescreens, its basically an image of the moment on your phone). i cant help you with radios as im new to that topic as well. +1 to anyone who can give me a good description of that.
Kernels CAN screw up things like GPS and WiFi. Not on purpose of course but sometimes certain ROM and Kernel combinations don't get along.
Radio is basically what a previous poster said. When thinking radio think of signal. A cell tower broadcasts a signal to the antenna in your phone, and the radio is what turns that signal into reception. Its a piece of software, a bit like a driver, that regulates that interaction. You can turn on/off the radio, which cuts the 4g/3g/1x connection to your phone on/off.

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?

Hello people,
For the past few months I'm having this issue which I find extremely [email protected]!!
Every few minutes, my phones just loses internet connectivity - the 3g signal appears to be normal during all the time, thing is, whenever I try to use any internet application - it just hangs. and then, after a minute or so, connectivity is back(again, for a few minutes).
I have tried flashing so many versions of modems - some improved it a little but most of them didn't help at all, or even made it worse.
Hopefully someone could help me with that as I'm that close to give up on this and buy a new phone.
Thanks in advanced.
Nir.
Which firmware are you running on your phone? What modem do you have right now and where do you live? Do you have problems with all apps that use internet-connection? Do the problems dissapear when you use wifi?
Just some information would be usefull

Yop.. forgot to mention a 'few' things...

Kernel: 3.0.31-CM-g7ce58e6
Baseband: I9100DXLPB
Android version: 4.2.2
I live in Israel, bought the phone in Thailand.
I tried flashing all available Israeli modems(from various cell phone providers) - none helped.
Problem disappear when I move to WiFi - as 3g connectivity moves to background...
Thanks.
I assume you've read the Rootbox threads to see if other people experience signalproblems?
Did you compare the connectivity with other roms? Stock-based roms for example...

If you've only tried flashing the modems bundled with stock roms from Israeli carriers, you haven't done nearly enough. There are literally dozens of modems available, you need to start flashing as many as you need to. This isn't going to fix itself magically.

I haven't flashed only Israeli modems but others as well. I've tried around 20 so far...
Question is, which direction should I choose? should I look for Thai modems or IL?
That depends. I know Israeli carriers sold (still sell ?) the I9100T, are you sure you don't have one of these ? If that's the case, I'd be trying modems bundled with roms released by the Australian & NZ carriers which sold the I9100T (I have one), and yes, the Thai ones as well.
If you do have an I9100, then keep trying any/every modem you can get your hands on. If it's not a carrier-side issue, this is really all you can try, unless you want to start messing around with RIL's as well. I've not found any difference in connectivity doing this personally (tho many people have) but if you get to the point of trying every single modem & you're sure it isn't a carrier issue, you might as well try. But I would leave this till last given many people find their connectivity messed up even worse by flashing an incompatible RIL.
Okay, so, I've done a fair amount of reading and searching about modems and RILs, including other forums, but I've still yet to find the specific information I'm looking for. (Most of the stuff that I've found relates to the i9100.) So if I missed the relevant post, I apologize, please direct me there.
That said, here's the deal. I've got an i777, which I have unlocked and am currently using on T-Mobile. I've flashed the stable CM 10.1.3 (Android 4.2.2). Its baseband is UCLE5. It's running well. I have few complaints, except for occasional low signal.
I've already seen this thread, with the different modems available: http://forum.xda-developers.com/showthread.php?t=1336958
I lost the link, but I also found a thread, possibly on another forum, where a T-Mobile user reported better performance with baseband UCMD8. I'd like to try it. I think I can manage flashing it on my own via CWM.
However, I've read in a bunch of places that it's also important to have a RIL matching the baseband version. I found a thread that gives a terminal emulator command to find your current RIL version (getprop "gsm.version.ril-impl"), and mine is "Samsung RIL(IPC) v2.0", which is apparently from Gingerbread.
So, my question is this: Should I also change my RIL? If so, 1) where would I get the appropriate RIL for the i777 with CM10.1.3, and 2) how would I install it, preferably without performing another wipe, reset and ROM installation?
Thanks in advance for your help!

You have nothing to worry about - just flash the i777 modem you want via recovery; you don't have to wipe anything, it will work fine. I wouldn't worry too much about RIL; over the two years of changing modems back and forth I've never encountered any problems regarding RIL (except for some wakelocks, but that's more to do with bad/weak signal than anything else).
To be clear, I'd still be happy for input from anyone regarding the i777's RIL, but I did go ahead and flash UCMD8. I've already noticed something new; my phone now seems to drop from H+ to 3G fairly aggressively when I'm not actually using it, then go back to H+ when I do, where since flashing CM10.1.3, it previously connected only at H+ or E. I imagine this is a battery saving measure. I'll have to see how it behaves for a few days.
Thanks for your response SteveMurphy. By the way, what baseband/RIL version do you use, if I may ask?

I'm on UCMD8,
The reason you're seeing 3G more often is because with the newer roms you have the ability to better control your network modes. For instance, if you want to use Edge you can manually switch to 2G mode. It's possible the older firmwares (GB, ICS...) had this option but I really can't remember.
Galaxy S Backdoor
So it seems my question about RILs was unintentionally timely, as Samsung's RIL for Galaxy S devices contains a backdoor that's been verified with proof of concept.
https://www.fsf.org/blogs/community/replicant-developers-find-and-close-samsung-galaxy-backdoor
http://redmine.replicant.us/projects/replicant/wiki/SamsungGalaxyBackdoor
I'm not sure which version of Samsung's RIL they tested, or whether they tested the I777, but it seems most Galaxy phones are affected.
Hope someone gets to work on this soon.

So I have been trying various MM roms but have finally admitted defeat and gone back to stock.
For what ever reason mobile signals for Virgin (EE) by us is not great, but the OPx has proved the worst phone I have owned yet with regard to making best use of what reception we do get, (Still have OP1 and S7 owners in the house, so have comparison).
However, all of the many MM roms I tried only made things worse with either weaker signal (or that's how it appeared) or they were unable to handle the swap between Wifi and Mobile, always requiring reboot, once I left the homes Wifi in order to get mobile data working!
It's so bad that I am even considering replacing the phone, but it's hard to find anything else in budget and size with same spec.
Thanks to everyone here who builds these custom roms and all the accompanying support, but for now I will continue with stock until I miss MM facilities too much.

It's just face value which shows yellow line in battery graph as far as I can tell. I do not see any difference now. Transition from wifi to mobile data is fine here. I am using turbo at the moment. Give it a try. If you wanna switch to a new phone, moto g4 plus should be good choice.

Hi, sorry not sure I understand the first part of your reply.
Anyway, the truth is that apart from this recent damned data issue, this is close to the perfect phone for me (seriously couldn't go for anything as large as the g4).
I have owned the OPx since release and though mobile data was never the best, it wasn't as bad as it has appeared this last couple of weeks. I am hoping that I have had a 'perfect storm' of events that led to 2 weeks of poor data connections/transfers. Bad roms, poorly implemented, weak mobile data areas etc etc.
Therefore, I am going to continue with testing different roms and set ups and hope that I can fix the issue, because there is no other phone on the market that comes as close to my perfect phone as the X.
I second Turbo ROM but also try Validius. Using it right now I think they feed it steroids.
For me this solution worked when facing troubles with mobile data on custom roms:
(Re)install the stock rom, backup EFS in Twrp, do a complete wipe, flash custom rom, restore EFS in TWRP, reboot to rom, restore standard settings in APN / mobile data settings, reboot.
It solved my frustrating issues, hopefully it does the same for you!

Many thanks for replying, I had indeed seen your thread and tried the solution, though initially I didn't think it had solved my issue. However, due to there being no other phone I care for, I tried another rom and then reflashed the EFS backup.
And you know what, I think it may just have worked this time.
Thanks for your help and others.

That's the one I'm trying and so far so good
It would be great if someone could create a flashable zip with oxygen RIL to use on any custom ROM. Don't even know if it's possible? Perhaps @RJDTWO can enlighten us, do you have the expertise? ?
Sultan's rom is the most stable regarding cell signal quality and speed. I have tried lots of roms, his rom is the only rom that comes near oxygen, every other custom rom has considerably worse lte speed and signal quality
@cokesucker it needs integration with the rom as far as i know, i think Sultan made the modifications needed for the rom to work with oxygen RIL
Folks, Ive dirty flashed the latest Rom, which I assume writes over the stoc EFS restore I had applied previous version of this Rom
Regardless, the difference in signal (as well as other areas) is noticeable.
I love this phone again, thanks everyone.

This is unfortunately not possible. The RIL itself is built with the ROM.

I tried most things and thought that occasionally I had solved it by 'forcing wifi' or whatever.
However, because much I what I did was reactionary rather than trying scientifically to identify the main issues, the causes probably got lost in location, reboots, resets, etc etc.
What I can say is that for 2 days, I have been using Sultanas latest Rom and it has worked flawlessly.
Nice, good to hear Bob!
I'm using that rom too, it's a real gem!
(Oxygen EFS restoring was still necessary despite the oxygen ril though)

That's interesting, I'm using "as is", and so far so good. I'm off on travels tomorrow will keep an eye on performance. Any issues and I'll restore stock EFS.
