[Q] Signal issue on KitKat - Galaxy S II Q&A, Help & Troubleshooting

Hey I flashed CyanFox 2.0.2 (CM11 / KitKat 4.4.2 based) and I've been experiencing constant signal issues.
One moment I have full bars and the next no signal at all. It happens randomly: during calls, while tethering, when on stand by.
I've tried different basebands / modems (MS1, MS2, MS4) but I couldn't find a fix.
Any ideas? I can always go back to stock JB but I really dig this KK rom, it's almost flawless otherwise.
Thanks

Make a backup of kitkat rom and try stock rom or some other rom stock rom is in my signature included stock kernel and modem. If it is working then its not a hardware problem then try maybe some other kitkat rom.
The link to stockrom in my signature is from xwms1 but i dont know or the moden works in every country

Did you check out calling anyone or receiving a call? Maybe its just the icon problem.......

In the end I flashed a stock 4.1.2 rom and the problem persisted, so I guess this is a hardware issue.
Thanks for the suggestions!

[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] P7510 on ICS 4.0.4 (XWLP5): unstable WiFi

Dear all,
I noticed that my P7510 running on ICS 4.0.4 (XWLP5) has an unstable WiFi connection when the received WiFi signal strength is not maximum (2 or 3 out of 4 bars). Connection often disappears and when trying to reconnect to the WiFi network manually, the there is no response. Turning off / on Wifi on my Tab is no solution to the problem either. Even a full reboot does not always help. I updated from HC 3.2 to ICS 4.0.4. after full flasing HC 3.2 first.
Is this a known issue? I cannot find any decent info on this. Or is there a ROM that fixes this? Please help. Thanks in advance.
I had no problem with the WiFi what so ever not with 4.04 and not with cm 10 jelly bean
Did you have that problem on 3.2?
Try and flash the official ICS from sammobile with odin
Thankfor replying. I did not have this issue HC 3.2. I went back to stock HC3.2 and updated via WiFi to official ICS v4.0.4. No official releases for my country for P7510 are available for my Tab, but other official ICS v4.0.4 versions I tried from Sammobile have same issue.
I'm thinking to go to CM 10 release, but since wiping is required and my P7510 has brick bug, I'm hesitating to do this operation.
Try the sammobile UK version that's what iam running and it had no problems
Cm10 is faster than official ics and gives u much more options It's a better experience at least for me except for a bug or tow but some people don't even notice them
About the brick bug I don't know what that is cause I had no problems wiping data so i can't help u their sorry

I already tried UK version from Sammobile, same WiFi issue when signal strength is not maximum. Regarding the brick bug: check this out: http://forum.xda-developers.com/showthread.php?t=1879941

I don't know what it's not working for you every thing oky with me
About the brick bug....... I just checked and as it turned out I too have the brick bug and I have actually ran EXPERIMENTAL-p4.zip
I have wiped the data and installed custom roms more than I can count......i don't know maybe it's over-rated or iam just lucky!!
Iam afraid to do it again now but he says here "Avoiding brick:
The only danger now seems to bi if you are on stock ICS ROM and you execute factory/data reset in Samsung recovery.
If you are using custom ROMs and CWM you should be safe because all custom ROMs/krenels have now removed mmc_cap_erase() from list of capabilities."
Iam running a custom rom so I don't know.....

[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 !

Slimkat Razr Lose Signal

Good Morning People: I have an issue with my Razr XT910. I ve just installed Slimkat V 3.8 (and before 3.4, 3.2 and 3.1) and in all versions i lost signal after a few hours. The only way i have to get it back is rebooting my cell.
I did all the wipes, I delete the cellbroadcaster.apk but the result is the same.
Any ideas? Besides that, the rom is incredible...
Thanks for your help!
Try other rom and see if you have signal problem.
Same problem
I have the same problem on my XT912, I also did all of the wipes (multiple times) and I am still losing service. I have flashed a pacman and carbon rom to test and have not lost service with those roms. I am a n00b as far as contributing to tweaks for roms but hopefully I will come across something. I hope this info is helpful.
