Has anyone seen where it won't get a signal or notice your sim card. Instead I just always have a circle with a slash through it where the phone signal meter should be. I've tried returning to stock and had no luck. I had loaded Macnut R9 and then the JPM802 kernel. That froze up the phone so I went back to the JPM800 kernel and its been doing it since.
Is it dead?
You might need to flash back to stock 2.1 thru Odin to see if that fixes it
I have flashed it to 2.1 and to the new Froyo and nothing fixes it. I think the hardware may be out. Didn't know if anyone else had seen it though.
It doesn't even recognize its own IMEI. Guess I'm contacting Samsung for a repair.
Actually the other night, I experienced no signal (with a circle), nor data (3G or E), nor wifi - kept on saying connecting than disconnecting. Only read Emergency Calls Only and I was on MACNUT R10 Rom. Similar to you. I resolved the my issue and it may apply to you, was try to reflash macnut 9 or 10 rom over your previous MACNUT ROM without any other additional kernal flashes. Just flash the rom which comes with a kernal built in. See if that corrects the issue. Before you do, remove your sim and place it back than flash the rom.
Yeah, I tried going back to stock, going to the new Froyo Stock, different macnut ones and more. Never could get it going.
So I noticed that my 3G wasn't connecting all day on my fascinate. I was running Evil Fascinate 3.3.2 with the nemesis ED01 kernel and the ED01 modem. So I flashed the EC01 modem. No 3G. So I completely wipe everything after a nandroid backup and installed stock DL09. Bam, 3G is back. I allow it to update itself to Froyo OTA. 3G working great. I wipe the phone and install the new Community Rom from scratch. 3G is gone again. I wipe the phone and I flash EF 3.4. 3G still gone.
So I'm back on stock Froyo. I'll do more testing later to see if rooting makes 3G go away again, but at this time I'm suitably freaked out.

Looks like smilepak had the same issue. see here also
Just a suggestion for when I get random bugs that others don't seem to get. I re-download the file i tried to flash, from a different link if i can get it. A lot of times it's a bad download
I think the piece of code in the unknown tethering module is phone home code. I think it's a combination of the phone home not happening, and high 3g usage triggering a disconnect on the other end. I can't prove it yet, but I'm trying to figure out a way to get tcpdumps for wireshark. I know my usage is very high right now.
This seems to be a problem alright..see this thresd: http://forum.xda-developers.com/showthread.php?t=1051543
Mine is low. For me, going to ed01 started the whole mess. Eve going back to dl09, didn't solve anything. The 3#g shows up and random disconnect every five minutes. Remind me of old modem days of bad handshake and reconnect loop. That is basically what it is doing. Once connected, hell of slow tried speed test and the result was horrible.
Looked through all settings values, factory reset, tried several different radio and from. All no such luck.

here's my problem:
when ever i leave phone to be in deepsleep mode,
i cam back to find it looking for GSM signal with no hope,restarting fixing the signal.
tried diffrent roms, CM7, MIUI,with all kind of kernels nothing works
phone condition is fine,did't drop it or hardware issues on it.
was working great for last 6 months, but after i flashed a ton of diffrent CM roms this starts to happen,
my thoughts:
could it be a NVdat.bin issue doing this?
if so, what i can do to let the phone re build fresh ones,
+ i have old backup of EFS folder.
can you share your thoughts please?
I had the same thing happened to me and my friend's phone in the last week. Both running the ported gingerbread roms. Had to Odin back and finally working. Not sure if it was the Rom or something. My phone says it shows a baseband of UVKB5 which is the correct modem.
Finally flashed back to froyo and had it working, now just reflashed a gingerbread rom and it's working again.

will try this option today and give a feedback.
thank u
Edit:
odining back to JFD solved the problem.
Been looking for a solution for the past 12 hours and have not found any.
Bought a stock i777 with 2.3.4, flashed with SGH-I777_ClockworkMod-Recovery_5.0.2.3 and a stock 2.3.5 AT&T ROM. After ANY kernel is flashed, I seem to lose WiFi capability. I have 5 wireless points near my house and it just gets stuck on "Scanning" and then the WiFi turns off. No points are even listed!
Currently running CW 5.0.2.3 kernel, 2.3.5 AT&T stock ROM, UCKJ1 baseband, kernel 2.6.35.7.
TL-DR - Flashed and lost wifi ability.
Which 2.3.5 ATT stock rom is this that you're referring to? Have a link to where you got it from?
I believe I got it from here: androidadvices.com/update-samsung-galaxy-s2-i777-gingerbread-235-firmware/
Did it work initially when you went to 2.3.5? You said you've tried some different kernels, at what point did you notice the wifi broke?
I even reflashed using kernel + non-rooted system package located in this thread: http://forum.xda-developers.com/showthread.php?t=1286432
Still no WiFi showing. Just says "scanning" then the wifi shuts off.
Update: Flashed Entropy512's stock package + nonrooted with no luck. No wifi. Flashed zetamax kernel after. Still no wifi.
Showed at that time: version 2.3.4, 1777UCKH7 baseband, 2.6.35.7_ZedomaxStockKernel.
Flashed again with a I777UCKJ1 2.3.5 ODIN package that I know will fix the WiFi. It shows version 2.3.5, 1777UCKJ1 baseband, 2.6.35.7 kernel.
Seems like if I flash ANYTHING else besides this the wifi stops working on me.
Solved problems for myself.
Completely unrooted, reflashed ATTGalaxyS2Unroot_SGH-i777.tar. This brought me back to the original AT&T firmware that came with the phone. I then flashed SGH-I777_ClockworkMod-Recovery_5.0.2.3.tar and subsequently used SuperOneClick 2.2 to root.
WiFi seems to be working fine now. I am now running a stock 2.3.4 ROM, UCKJ1, kernel 2.6.35.7...Clockworks version.
If anyone else is having the same issue this should help.
Thanks for the updates. Sounds like a frustrating battle. Glad all is well.

Hrrrrm Having the same issues and the only way I could manage wifi to get back on was going to 2.3.5 which had it's own set of issues. I tried following your steps but one thing I noticed you said you were running UCKJ1 but isn't that 2.3.5? When I flash the exact same files I am still stuck without working wifi
Still noobing it up here - hopefully I can either stumble upon a fix like you did or spot someone else's that matches my issues...
Avoid that androidadvices.com **** - Half the time they link to firmware that isn't even for the device it claims it is, carrying a high risk of a hardbrick.
I only experienced this when I was trying to upgrade kernels using the SHOstock ROM. I get no wifi with siyah and can't send MMS with Entropy's kernel. That's the only time I've had those issues. Maybe you had a bad download? Glad you got it fixed though.
Just to clarify, those kernels work great with most other ROMS I've tried them on.

Had the same problem
I had this problem (with wifi, not mms) after rooting from 2.3.6. I eventually flashed Zedomax's kernel using mobile odin and wifi functionality was restored.
I still haven't moved on from there, but probably will sometime this week.

Weird, I cannot think of anything that would cause MMS to fail - what sort of errors?
It's happened to me several times after I flash a kernel. when I attempt to send an mms it just hangs and says sending but it never goes out. Could it be a conflict as I have Chomp set as my primary messaging app? Although if that were the case it should be able to send from one or the other but it doesn't. Can't remember for sure but I believe that I may have flashed the kernel cleaning script beforehand in each instance. The only way I've been able to fix it is to reinstall everything starting with the ROM. I'm sure it's user error.
As info, steps I took to try to fix before I restored:
1) reflash kernel
2) flash radio again
3) tried all 5 radios released (not a radio problem I'm guessing)
4) wipe dalvik and reflash kernel
5) run kernel cleaning script and reflash kernel
No dice, it was bizarre. Is this even the sort of event that you could get an error log from? There was no FC or any error message, you know? If it happens again what can I provide you that would help...can I do a logcat or whatever? ;-)
By the way,I could receive mms, just not send.

Factory Data Reset restored wi-fi
I was on UCKK6 (2.3.6) and rooted by flashing Entropy512's Return/Unbrick to Stock (2c)
http://forum.xda-developers.com/showthread.php?p=18576627
and lost wi-fi (scanning then wi-fi shuts off).
Since I was reverting from UCKK6 back to UCKH7, I had to do a factory data reset
(Menu > Settings > Privacy > Factory Data Reset)
based on the info in this thread:
http://forum.xda-developers.com/showthread.php?t=1286432
I got wi-fi back once I did the Factory Data Reset.
I'm having the same problem
Giant noob here =(
Could someone post step by step instructions on how to unroot so that I can restore my wifi?
For example, if in fact doing the factory data reset as described in the post above me is the correct course of action... is there a way to do a backup before so that I do not lose all my apps and stuff?
Thanks

Hello all, its been a while.
My fascinate died the other day so I borrowed a relatives old one. It came stock and I upgraded it to the latest cm 10.1 nightly then straight to cm 11 android kit kat 4.4.2. After everything was all said and done the phone was running great, the only problem I am having is sending MMS messages with pictures. I checked to see what modem was installed, I think it was eh03 but I could be mistaken. Thats when I remembered having the same issue or similar issues with cm 10.1, I was able to fix that problem a while back by flashing ec09 with odin on my other phone. So naturally I flashed the EC09 modem to this phone but nothing has changed, the picture messages wont go through . I checked in the about section in settings and it shows EC09 is installed. Also I remembered using phone in odin to flash it last time so thats what I used this time, is that wrong?
Basically I am wondering if anyone knows which modem I should be using or if anyone knows of another fix to t he problem.
Also I have been having a lot of trouble finding download links for all the other modems so all I have used are EC09 and EH03.
MMS usually has nothing to do with the radio, it's an issue with the ROM unless the modem was improperly flashed. i use EH03 without issues, it gives me the best results.. i think.
