[Q] i777 modem/RIL questions - AT&T Samsung Galaxy S II SGH-I777

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.

[Q] GB.XXKPF.WT-0.2.0 ROM - anybody used it?

I wonder anybody flashed GB.XXKPF.WT-0.2.0 ROM for Galaxy Player 5.0 INTL (YP-G70). Is there any bugs? Any improvement for wifi reception signal?

The only issue I see so far is some camera apps will have upside down images but I am not sure if it is even a problem of the ROM or the app. Other than that there is nothing bother me when using the rom, but I have to say that I never use any of those Samsung apps. So there may be problems that I am not aware of.
As for wifi reception, if I am right next to the router, I've got a Rssi value of -34 and Elixir2 says (98% - strong). If I am in another room (there is a solid concrete wall between the device & the router), the signal will drop to around -86 and Elixir2 will say (31% - medium), which is still usable.
Thanks WT. I used to have Skype camera upside down problem when I was on Froyo, but when upgrading to GB, it was solved. However, wifi signal was weaker than Froyo (maybe ~30% less?). Lots of forum mentioned it's a common problem for GB (regardless of model).
BTW. How differentis this ROM from G70XXKPF-rooted-rj10 (also yours)? Tinking to flash one which is more stable and battery efficient.

There is no modification to G70XXKPF-rooted-rj10 except for root and a custom kernel. If you prefer stability, G70XXKPF-rooted-rj10 will be a better bet. You can try out various kernel versions to see which one has better battery life.
The GB.XXKPF.WT ROM looks similar on the surface but all the jar files and apk files were decompiled and compiled again (because of modding). So there is a higher risk in using this ROM. Although it looks stable on my device, it is hard to say for others. Actually two users have just reported problems about flashing the 0.2.0 ROM.
As for wifi problem, I don't really see that my self. If you have some links to GB wifi problems, I can have a look.
One in our forum mentioned it too (after upgrading to GB):
http://forum.xda-developers.com/showthread.php?t=1141893&page=13
I checked my current wifi reception and have similiar signal strength as yours. However, if you revert to Froyo, you will find big improvement immediately esp a distance from your router. Should get plenty when google "poor wifi reception Gingerbread Samsung galaxy S". The other is problem of connecting hidden SSID which can be patched from Market (HiddenSSID enabler).
I can find patch for i9000 not YP-G70.

Wifi problem can be difficult to reproduce and fix because of every site is unique. The patch you found is interesting though. I peeked into that patch, it needs further study because the patch includes some binary files which looks like firmware for the wifi chip. If our player use the same chip, there is a chance that the patch may work. Or we can try restoring the firmware of Froyo and see if it will work with the current kernel. (These are all speculations though.)
Just did a binary compare of the wifi firmware of this patch with the firmware I found on our device. They are the same! So the patch you found can potentially be used on our player.
It is said only suitable for XXJVS. I've asked if it's suitable for our device (bottom of their thread), and answer is no. Interesting why it's only for one specific rom? WT, wonder if you feel better wifi reception when you were on Froyo?
Is Wifi config in any relation with kernel?

If you unzip their "patch", you will see what is really inside. There are a couple bin files, I think those are firmware of the wifi chip (often closed source and only binary is available). Other than that, there are a number of text files for configuration of the wifi which can likely be tweaked. They didn't patch the kernel or the android framework.
Their way of flashing is odd though because the update script of the 2nd patch will overwrite what they have patched in the first patch.
If the firmware bin files are exactly the same, then what we need to do is to tweak the setting.
I am not good at this at all. Can you pls tell what tweak have they done by comparing their settings and original one on our device. Is conf file the driver for wifi chip? Really hope wifi reception can be improved on our device since it is the only way to connect internet. Currently, the signal is a lot weaker than your laptop (and only close to laptop when it is on Froyo which I am reluctant to go back).

Oops! What I want to say is "I haven't done that before...". Anyway, I will first do a comparison of wifi related files of different ROM first. That will give use some idea where to start.

[Q] Baseband Versions

Sorry if this has been asked, but I have not been able to find a solid answer yet. Can I install " [ROM]UCLC2 Official ICS "Leak" I777 (3-27-12)" on my S2 with the baseband version UCKK6 and be alright? I had an incident where I put a kernel that wiped my wifi capabilities a while back and wasn't sure if it was because it contained a different baseband. I'm not sure on which modems/basebands I should stay away from?
Thanks.

That would seem to be true, since the modem.bin "image" is really just a mini-kernel and real-time OS (ThreadX I believe) loaded by the modem and only talks to Android via the RIL abstraction layer.
But on the Captivate, when using an i9000 ROM (similar to the use of i9100 ROMs here) you actually had to use an i9000 modem too. In fact the rule generally was, the modem had to match the kernel, as we had separate kernels for i9000 and i897 ROMs. This of course opened up many more options since the international variants inevitably have many more modems available. Point is, on the Hummingbird platform, the modem/kernel (and usually ROM) were somehow interdependent on each other. Maybe due to quirks specific to the RIL in each? Or maybe something else? No idea, and not sure that anyone ever bothered to figure it out. (Why people aren't more intrigued about trying to "hack" the modem binary is beyond me. I don't care if my phone violates the law or gives me cancer as long as I get better reception and data speeds... )
Any ideas as to why this wasn't the case with the i777?
In particular on the Captivate, running a mismatched modem would result in voice calls not working properly, though data would usually work, which isn't all that dissimilar from what happens on the i777 with a mismatched modem/kernel/ROM combo.
Just looking for any solution that would let us run i9100 modems on the i777 in particular since there is no proper way to adjust the bands selected by the modem. Aka, that whole stupid RAT restricted bull**** business that AT&T seem to enforce on the UCXXX modems.
Thanks in advance!
And PS, I'm not kernel developer (though I am studied in C/C++), but if you pointed me in the right direction as to where I might be able to find some useful RIL debug output, I'd be willing to pour through some logs looking for anything interesting.

I think that in the case of the I9000 vs. I897, the modem/CPU audio interface may have been entirely controllable by software.
On I9100 vs. I777, there appears to be some hardware in between we don't have control over. As a result:
An I9100 modem on I777 results in no audio regardless of kernel.
An I9100 kernel on I777 results in no audio regardless of modem. I know this end of things - one of the digital I/O channels is set up very differently on I777. Master instead of slave I2S (or was it the other way around?), 16 kHz sample rate instead of 8, and a few other settings are different.
There might be something about that "in between" block we don't know about and can control with the right knowledge, but right now - there's an unknown black box somewhere and it prevents I9100 modem firmwares from providing call audio.

[Q] Modem/Connectivity issue

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

Rom: RootBox V3.8
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...

That seems quite weird.. The only thing I can come up with is 1) a hardware problem, or 2) you live in an area where the signal is crap

Anyone else...?
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.

[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

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.

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

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:

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 ;/.

Still - if you have been flashing different roms and never done a thorough clean I recommend you do!

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
- Dario
