My S2 has the no signal icon showing. This happened after the phone crashed using a custom rom about a week after installation.
Since then to fix it i have restored my nandroid backup to the previous rom, restored it back to an official firmware/kernel. Even tried different modems but still i have no signal. I have checked and the phone still retains the correct IMEI number that is on the phones original box.
Anyone have an idea what could be causing it or could it even be a hardware fault?
Try to re-flash your regions/carriers modem+ril. But first, try with a different SIM card, maybe your SIM died.

Maybe you should try to go to recovery and format cache and dalvik cache in advanced.

Tried that, no luck. Waiting on getting my hand on another sim card to try that.

Hello,
i have a problem with my wifi.
i 've just put version 2.3.7 and my wifi doesnt show me
the available networks.i cant find any solutions.
please help!
im facing a similar case which the wifi signal disappear after 24hours i install/recover back to the normal state.
i set a backup point just before everything went wrong, and whenever the wifi signal disappear after 24hours, il go back to CWM and recover the previous state again and again.
initially i can go online with wifi, signal detection is ok. after 24hours, the signal disappear and i cannot detect any wifi anymore. restarting the unit, clearing cache does not cure. i even tried the method given by SpitFire-ZX this, yet the is no option for selecting NO and YES in step (6). the system jump directly to a reboot and log in like usual.
anyone?
Reinstall the rom, with wiping data/factory reset, and wiping dalvik cache.

Yes, install miniCM7 from zero
I think your router may be involved here..Because the given ip usually expires in 24 hours,
I had the same problem with all, and i mean ALL 2.3.7 roms
Whats worse, my wifi would disconnect every 20~30 secs. : /
So then i reserved an IP for my mobile onto my router..and viola! wroks pufect!!
Do check out how to reserve your phone onto your router, I strongly think that maybe your problem!!

I didn't have a prob like this 'til now, but did u try to make a clean full wipe reflash?
Wipe data, factory reset
Wipe cache partition
Format data/system/cache
Reflash Rom (later maybe kernel, too)
U have connection to inet? All settings in set correct?
CHEERS

I don't think it's a problem with the ROM as it worked fine until i tried to dual boot with resurrection remix via siyah 3.1 kernel.that's when the infamous eMMC chip error came up.so i switched back to cmw recovery and sensation. Flashed n wiped everything. But everytime i restart the date and time goes back to the default one. And yes i have set the correct settings and everything.

Get gotbrickbug app by chainfire from the market and check whether your eMMC chip has been fried or not

If your eMMC chip had been fried, you wouldn't be able to do a lot with your phone. I don't understand why you're linking this to your date/time problems. Also, Chainfire's app won't tell you if your eMMC chip is fried, just whether a particular erase method could brick your device.
Well when i enter into recovery, i get three four files missing.Those which you get if your chip is fried. And yourphone can continue working fine with a fried chip.only when the bogus corrupted sector is accessed again does it gets your phone into a Brick.Plus am not able to dual boot in siyah anymore.
Emmc being something to do with cache. I think the local settings like time and date is not getting stored to be brought back during a reboot.

Well, the phone was running stock 4.0.4, I try flashing the t-mobile modems (cwm, root then flash the radios) but for some reason the phone became very laggy and unresponsive. I thought it was due to the (Tmo_SGH-T989_KID_radio_ATTNOTE) so I regret the idea of using my gnote with t-mobile and decided to go completely stock, but still the same proble.
Are you wiping data and caches properly between flashes ??
Different rom architectures are not backward or forward compatible.
It's likely your rom is contaminated with old data...try this first.
Boot into recovery ...
Wipe cache, dalvik cache, data, and then reboot.
Especially when booting from an Odin restore ...the data will remain on those partitions, and it borks the phone up pretty bad .....g
Edit: also, do not restore data into the new rom by using apps like titanium backup.
It will force bad data to the phone as well.
Restore only the app itself, and not data when prompted.
Not sure if you use those apps, just thinking out loud ....g

i have a weird issue and i need your help with it guys/gals
my phone doesnt allow me to connect to any network, it doesnt even ask for the sim pin lock code
the ONLY happens when i try to use an official stock rom
if i put a custom rom in it then all works well
i am lost right now, here are the things i did
checked the imie, its fine
works well with custom roms, have tried that already
put a different sim card and the same issue turned up
flashed official rom using odin after performing a data/wipe reset and all
the baseband shows up just fine
am i missing something?
Edit: just found out something new, when i go to security settings and change any of the sim stuff (lock or change pass) network works just fine
what's going on here
here's another thing, when i hold down the power button it just automatically shuts itself off, no options for some reason
Edit 2: after putting back the custom rom, i noticed that the imie changed to the 00499xxxxxxxxx whatever it is, so i flashed back the backed up efs and now imei is normal, does this mean anything? changing from stock to custom loses imei?
The shutdown syndrome is caused by not performing full wipe before installing jb. Clear all caches and reflash jb from scratch.
Edit: the 00499... iemi is a generic one, it's useless. Use only your own, from the backup.

what are you talking about??
In the i9100 official jb thread many complained about the shutdown menu issue. It's caused when the dalvik cache and factory wipe aren't performed before jb install.
I didn't notice that you're talking about the G model, and do not know if jb came out for this model.
Regarding the iemi - ignore this part, I read it in another forum, maybe it was related to a different device.

no offense, but did you even read my op?
i didn't mention anything about jb, i just said official rom, that's all
i'm talking about any official rom, all of them.
for some odd reason its ok with gingerbread
this is what i do before installing,
full data wipe/factory reset, cache wipe, dalvik
pull battery, download mode
install rom,
i even tried to put gingerbread and let keis upgrade it but it gives me the same issue after it becomes ics or jb
Maybe modem issue.
What modems you've used when in custom ROM?
If GB worked without these issues flash it's modem when on ICS.

Hi. I'm running CM 10.2-20131014-NIGHTLY
I have been having a few issues with the phone recently.
My wi-fi doesn't work, I can't connect with the wi-fi of my house. Sometimes it will be stuck with obtining the ip adress, or says connecting but no luck.
I don't have bluetooth anymore, it says turning bluetooth on (the key is grey not blue).. and then goes back off. I had tried with the botton from the notification bar but it doesn't work either.
I don't have any network connection (3G, G, H, H+), the phone works fine with incoming/outgoing calls, sms but not internet.
I don't know what to do, I have been using this version from a long time and never had problems.
Go to recovery and wipe cache and dalvik cache in advance and reboot. Test it. If its not working wipe data and test. and if all else fails full wipe and reflash rom and gapps.

I have been searching and I found that CWM keeps untouched the internal SD and keeps rom and kernel, so..
If in the worse case i have to go back to factory how can I do that?
I really don't want that...
The only ways to go back to default are to DL the firmware from sammobile and flash it with either....
PC Odin...
or
Mobile Odin....

What I want to know is if there is a way to fix those problems without having to get back to factory.
Well you could always try @hawkerpauls ROM and kernel nuke scripts and then re flash your ROM.......

kernel scripts?? Can you explain this, please?
What they do, as I understand it, is perform a 'deep' wipe of the intended partitions prior to flashing a ROM....which essentially allows you to 'clean flash'.........all the info you need can be found on the thread.....
http://forum.xda-developers.com/showthread.php?t=2100558
Edit....having read the thread, it looks like I was wrong.......looks like a KERNEL wipe script is not available......might still help to 'nuke' the other partitions though.....

Wi-Fi was working a few minutes ago but now back to not working.. In my phone appears the wifi of my home and says that the signal is excelent but when I press 'Connect' in my phone appears like the connection is poor and don't connect..
I was wondering if reinstalling CM would work..
Today I 'fixed' the 3g connection problem by changing some APN values, now I can use Whatsapp but I can't connect to internet.
First the following message appeared: ' authentication via the proxy server was unsuccessful'.
Rebooted the phone, now this message doesn't appear anymore but pages won't load, play store says 'Connection time out'..
Phone calls/sms working fine.
Any suggestions?
