I'm having a lot of trouble with my S2 right now. I've been running CM10 since I got it with no trouble at all. I updated to 11 when it came out, again with no problems. Basically what happened is I flashed the stock ROM so I could use the video camera, then just restored back to CM through recovery when I was done. I did that two or three times, then suddenly I have no mobile data on any custom ROM, OR on the stock ROM I made a backup for. Voice and text works fine, just no data, either 3G or 4G.
I eventually un-rooted and went completely back to stock, and that got data working. I rooted and got recovery installed, and everything's still working fine. But, no matter if I try to install Cyanogen fresh, or try to restore a backup, I don't get mobile data. If I restore a backup of the last stock ROM, data works fine. From inside the stock rom, I did a master reset and updated PRL and profile.
Does anyone have a clue as to what I'm doing wrong?
Okay, I noticed that my MEID and some other parameters were 'unknown', which according to Google can mean a bad modem. So I flashed a new one, and all is well.

I have started having a wifi problem. Everything looks to be connected and working properly (ie. status shows wifi, wifi settings show connected to my router with IP address), but I can't access the internet. If I toggle airplane mode, it will work. It will work fine, but will stop working again after asleep for some unknown time. I am currently running EL26 modem with Calkulin ROM 2.7 with the original kernel. I suspect the modem. I can't pinpoint when the problem started, but I think it was after I started flashing modems from my OTA EK02. I have restored ROMs that I know worked and now have the same problem. I have reflashed EK02, EL13, and EL26 to no avail. I restored to my current setup and did factory reset, wipe cache, and wipe dalvik. no good. I would prefer to avoid, but next step is to go back to EK02 OTA and start over slowly and proceed forward. Any ideas?
Edit:
I have corrected my problem, but have no idea what the problem was. I odined back to EG30. I was prompted for the OTA and took it. I did one root and installed EK02 stock+CWM. Installed a couple of my key apps and backed up. Rebuilt my system a couple apps at a time. Got everything working in this stock as possible environment. Once I confirmed no problems including wifi, I backed up again. I then restored my Calk 2.7 rom. I have been running with no problems for a couple days. My conclusion is a bad modem flash. I flashed modems from Calkulin's and qbking's threads. I am leery of flashing modems, but at least I have a pretty easy way back. Before I forge forward, I am going to delete all my modem zips. What is the best source for modem zips?
I was running CM9 without any issues (CM9 kernel) and did a complete wipe and flashed the ACS AOSP 4.1.1, and all seemed well. At some point I lost 3G, then it picked up 1x... and that went back & forth for a while... then eventually both stopped connecting and now it won't come back at all.
I even restored my CM9 nandroid and I still don't have data.
I didn't flash anything but the ROM and the gapps linked in the ACS thread, and like I said everything was fine for a bit.
Any ideas? Voice works, but no data.
I updated Profile & PRL with WiFi on, both said successful, but when I turn WiFi off the data connection doesn't happen. Yes, Mobile Data is turned on, and I've tried all of the different settings.
EDIT: I even flashed CM9 back over top of itself... nada. Next up... full wipe and fresh CM9 flash again... /sigh ***WAIT*** That fixed it...

I tried to back up with the tar option within clockworkmod, but the phone reboots during the back up process. Anyone else seeing this?
I nandroided a backup set as well. The one I performed yesterday actually reads with a time/date of 0:00:00 on 1/1/0000 and is unusable; phone resets when attempting the restore. A backup made on 8/24 is fine.
So could just be something w/ the rom, or with the rom + JB. Which JB are you running?
I'm on PhantomPhreak53's latest alpha (4.4). I didn't have issues with any of the previous versions. It was strange I tried creating a backup yesterday (8/28) it created a folder that was dated (8/29).
Hmm, odd.. the date on my restore was really odd in that it showed 0000. It actually did give me a partial image, but not complete.
I don't recall which build I'm on, version shows 20-20120822 unofficial d 710.
Will be nice when this is complete and great and not having a) the airplane mode issue, b) volume / voicemail issue, and c) horrid battery life. Yeah yeah, I know roms aren't necessarily responsible for battery life, but I figure if its sitting doing nothing for an hour, it shouldn't drop 15% of my battery.
I just tried backing it and rebooted while backing up data. The folder has the right date now (2012-08-29.19.40.57), but still incomplete.
I just want to back up, restore my GB room to update prl and profile. I just updated my modem to FH23, hoping it'll cure my slow 4G speed. right now 4G is benching slower than 3G.
Hmm, this may be a lame work around, but try this.
install AppBak, create a 'backup' of your apps (it's just a list of them with an easy way to reinstall one by one)
remove everything you can that is a regular installed app, then try running your nandroid backup.
I ended up flashing 4.3 and create a backup successfully. I updated prl/profile then restored back 4.3. Then updated to 4.4. I didn't make any difference in my 4G speed though.
Good it worked out.
I'm still working on trying to figure out how to restore back to an CM with ICS, so I can triangleaway and update to JB again. Ugh.
They posted that this is a known issue with the backup/restore through recovery best bet is to mobile Odin back to el26 do a backup then Odin restore the stock kernel for cm10 then restart should work

Hi everyone, this is somewhat complicated and il try my best to describe what happened.
My device is a i747m (rogers).
I was running CM10.1 (running gapps-jb-20130812 and CWM recovery 6.0.4.3) for a long time, tried to update to 10.2.
(i messed up on 2 things.I don't think i cleared neither of the cache or data and also didn't have proper gapps which would be 20130813).
After installing 10.2 through recovery, it would just stay in the boot Cynogen booting logo.
i restarted into recovery, since my old CM10.1 zip was still there, i installed that instead, but same thing happened, it would just stay at booting logo.
I had made a nandroid back up from before all of this, and so i wiped data, dalvik cache, cache, formatted system, and i recovered into that, which was a stock 4.1.2 rooted (rogers).
However, nothing worked, only WiFi. I couldn't make any phone calls, send/receive messages, or get data.
I then used ODIN 3.07 to flash the new stock 4.3 rooted (rogers). WiFi worked as before, but i still couldn't make any phone calls, send/receive messages, or get data.
i then re-installed the latest recover 6.0.4.5, and installed paranoid android 4.4.2 and gapps for this version. But still nothing, so i went back to the stock 4.3 rooted.
4 months ago, when i made the nandroid back up, i also made an IMEI back up as well (i did not do a full imei/NV/EFS/IMSI/data backup) , i only had my IMEI backup, so i wrote using "NV items reader writer" the IMEI back onto my phone, and now i can recieve/send messages, and get phone calls and make phone calls. wifi also works.
But my data is stuck in Edge, its extremely slow, takes 10min to download a 15mb file.
so far:
-The APN settings are correct
-my IMEI number in settings menu, matches the one on the back of my phone.
-network mode is GSM/HSPA/LTE
-i have installed the latest modem for i747m through CWM recovery and also tried slightly older versions.
i am pretty much lost and i dont know what i should do.
-rogers has told me to use kies and perform backup and then recovery, apparently that will factory reset my phone.
-should i simply use kies to install the latest 4.3?
-does anyone have the imei/NV/EFS/IMSI/data files? or the full NV file?
-should i install CWM recovery and wipe everything that i can? and re-install stock rooted 4.3?
-should i use QPST to fix my IMEI? <-- dont know anything about this, noticed a few threads.
i have used these threads in all my rooting and so forth.

Hi,
Yesterday I posted about why my Wifi and 3G didn't work after flashing CM11. With the help of of engine95 I got this to work (thanks!) but now I am running into another problem:
The GPS doesn't work. As far as I can tell the standard solution is to flash stock again and get a GPS fix, then go to back to CM. So I flashed ZVC_Stock_Root.zip again. This worked yesterday, but today it shows a message "cyanogenmod account has stopped" and reboots after a while. I have done a factory reset and wiped Dalvik cache but the message still appears.
Does anybody know how to fix this?
Delete system in recovery and re-flash ZVC stock zip to get rid of pop up message.

This ^^^^^^.
Also. when you flash to the stock ZVC, make sure everything is working and make a backup in TWRP/CWM. That way you can bounce back and forth when CM/AOSP Rom's have issue's that need to be fixed with stock. ie update profile prl, GPS.

Thanks a lot, everybody. Formatting system allowed me to boot up stock and get a GPS fix. I have backed up stock and can switch easily between CM and stock now.
It took a while but now I have a fully functioning Optimus G with CM11.
