I had the exact same experience with my wife's phone that I bought of ebay. I even flashed a variety of RIL's (radio interface layers) and different modems. I'd never had the problem with my SGS3 before, and have hundred of different roms on it.
Anyway it seemed to be a kernel issue and after trying ever combination possible I found that wifi would always work perfectly on any stock based rom or any CM based rom (assuming that hey used the CM kernel). It wouldn't even work on a CM rom if I flashed a different kernel such as Yank's, Boeffla or Googy.
Also at the time I trawled the net looking for answers and found one or two others that had the same issue, but could still use stock Sammy or CM. Strange... almost felt like it was an odd batch.

[Q] Stock rom instability

Good morning everyone
Seems to be that my GSII has serious issues running his stock rom (continuous reboots, not-working 3g etc.). I tried several factory resets, but nothing worked 100% . CM fixes some of my problems, but the only full-working custom rom is MIUI, that seems to be stable and very neat. Despite that I still prefer the custom rom (yes I'm probably insane), or a more traditional one like CM and I really would like to understand what kind of problems can generate such a massive amount of errors and reboots.
Could be a hardware problem? MIUI works fine, I can't explain why I still got problems with other ROMs.
Sorry for my bad English, thanks in advance
Without telling us the version of the stock rom you are using, we can never give you any answers.
I'm currently using
2.6.35.7-I9100XWKDD-CL161513 [email protected] #2 Kernel
Gingerbread.xwkj3 Build
That's not the original stock ROM, just one I found (here on xda I guess...)
Is there some kind of hardware-check I can run by myself, just for exclude manifacturing defects?
if you want to check to exclude hardware defects, u could go to the dialer and press *#0*# .. it will give u a list of tests which allows u to pinpoint any hardware defects ( if it exists) .... but if the problem is with the 3g, you could reflash your modem..
Initial problems were strictly connected with 3g's use, after a few hours of use i've noticed slowdowns using sms, then it started crashing and random rebooting. That's the same reason why I initially switched from original ROM to CM. I mean, I know that Samsung's ROM is not the best one at all, but I can't figure why it's so instable on my device.

As that the oldest stock rom try a newer one .

Updating: now my GSII works with latest stable Cyanogen, except for the 3g that's still not working. Should I reflash modem, as suggested by roophz?
That old kernel is known to cause random reboots.
Update to a newer stock rom.

Update 2: I switched from the old stock rom to the latest cyanogen stable version, then to a newer stock rom and then back to MIUI again. Still no life signals from 3g.
How is that possible?

[Q] No Wifi at all on ICS and JB Roms

I've been trying to fix this for weeks, but I just can't find a working solution so I am asking you guys for help!
My WiFi works fine if im running a Gingerbread Rom, I currently have WIUI (the GB Version) flashed and the Wifi works fine. It won't work on any ICS and JB Roms however. I've tried MIUI, CM9, Resurrection (Both the ICS and JB Versions), F1 Galaxy Nexus, Lite'ning Rom, Paranoid Android and more, all I get is "Authentication Error". I tried to restart it several times, change the Network Security, the Radio Channel (I dont know it thats the proper translation, excuse my english), and installed various Apps (WiFix and such), Kernels, Modems etc but none of them seem to help.
I'm so frustrated with my Galaxy S2, so I'd be really grateful if someone could help me out!
You tried many ROMs, but WiFi is controlled by kernel :silly:
So, try other kernels.

[Q] [XXLSJ] Modem issue

Hi,
Sorry if my question looks noobish but I can't find anything relevant. I was running NeatRom Lite for a while without major issues except some touchwizz FCs, and decided to install the latest Omega. Now from times to times I got disconnected from the network and I can't even register on any available carrier.
1) Do you think a new modem will solve the problem ? I thought this was RIL related but the application Get RIL is only for AOSP/AOKP roms...
2) Are all modems working with XXLSJ ? The signal in France is really bad so I'd really like to change it...
Thanks in advance

Modem that comes with LSJ is LS6..I never had a problem with it. Try another modem like LQ6 .And i have used neatrom lite for weeks. But i never had a single FC, Specially with touchwiz. Are you sure you did a full wipe before installing the rom??
Ok I'll give a try to LQ6, thanks !

[Q] instability because of kernel?

Hi all,
Until recently I have been having very unstable results with my SGS2 (gt-i9100), every time the phone would freeze, overheat, use most of the battery in 2 seconds (figuratively speaking that is) or rebooting itself.
Some people on this forum told me to try a different kernel or roms, something I did and well no real improvement, I tried combinations of ressurection remix, omega and kernels such as siyah and dorimanx (I tried more but these are the ones I still remember by name)
Luckily (or unfortunately) I love my phone and android so I didn't really want to change hardware.
Couple of weeks ago, I figured that maybe I should try yet another rom and... SUCCESS!!
Ever since flashing AOKP milestone 1 everything is the way it should be (well to be honest first thing I always do when getting a new phone is rooting it and getting a new rom, so I am not sure how "normal" out of the box operating of an android is :silly
So basically my question to you is:
does the instability have anything to do with the kernel? currently using 3.0.31-cm-00008 (which incidentally, is that CyanogenMod?)
if it is related to the kernel, anyone has any suggestions to make dorimanx/siyah work (as they seem to be pretty popular here on xda, I'm guessing it has more to do with me)
and less kernel related, if a rom is AOKP based (or CM or whatever), does that mean that this rom has all the bugs from the base + the things the specific rom has?
Thanks!

1. May or may not be, usually it's kernel related, yeah that is the usual kernel made for CyanogenMod
2. The latest dorimanx does work fine with xwlsn and so does the latest siyah for xwlss.
3. An AOKP rom has different frameworks and usually is more buggier than stock rom, because of closed source codes (blame Samsung) several features are disabled or improperly functioning.

[Q] Modem issues

Hello everyone. I've tried many modems (XXLS8, NELP4, XXKI4, BVLP7 etc.) but each of them had some different issue. First was loosing network, with second the front speaker stopped working, with some I wasn't able to hang up the phone - the red button only minimize "the call" to status bar... Just noone worked fine :\ I don't know what to do yet! Any advices, does RIL have to match with modem? (I have CM 10.1.3 stable)
I've had these issues when I've accedently flashed Samsung modems on CM ROM. If you're on CM or AOKP type ROM - reflash the ROM to get the default modem back. Don't flash other modems unless you're 100% sure it's made for non-stock ROMs.
Hey, I also had some issues tried more than 5 different modems that were supposed to be good and none worked. But then i started to go through all of the modems that are linked on the cyanogenmod wiki site for the i9100 and the 4 one solved it.
i think you should just keep on trying different modems. If you have issues with all 12, you can start looking somwhere else. Also don't touch the ril its apparently not a good idea.
