I flashed to CM7 awhile ago and it had been running great on my phone. Within the lass day it started having problems connecting to the internet. Now, when I updated to the 7/21 I lost internet completely. Since I thought it could be a roaming type of issue I flashed back to EE19 where data worked fine. I did ADW DEBUG anyways hoping it would bring back data in CM7. I can't figure out how to get data back with CM7 even after multiple data-wipes and reflashes. Does any one have any ideas? I can always go back to 2.2, I'm just hoping that I could keep using 2.3.4.
Try flashing back to the build before 7/21 (whatever date it is).
Tried a clean wipe and went to 7/21. Boot looped after installing gapps. Wiped clean and went to previous Cm7 and it works fine. My phone must not like something about the 7/21 version.

Hi, I'm not sure where to post this or what details I need to provide..
Basically I flashed CM7 RC2, and after few hours of usage, my phone receives no service/signal at all (with the grey cross icon on status bar).
I can't do a manual search for my network, reboots won't work, taking out battery and SIM card won't work either.
I flashed back to my nandroid and back to RC2 a 2nd time and the same thing happened. Tried different kernel and same thing happened. and during the "no service" state, a process called something like "android.phone" process keeps force closing non-stop every few secs.
any idea/advice what might have gone wrong? any way I can troubleshoot it?
P.S. I was using Stock 2.3.3 rooted with netarchy CFS 1.2.5 before flashing CM7
Hi. I narrowed down the problem. My phone receives no signal when I use the toggle 2g/3g button, then the android.phone process force closes continuously.

I had the exact same problem 2 day ago with RC2. The problems started after running fix permissions. I discovered that if I go into airplane mode, the force closes stop. But as soon as I tried to go back to cellular service, the fc's came right back.
I was able to fix the problem by putting it in airplane mode, wipe data/cache, and then flashing cm7 RC2 again right on top of the existing install.

currently the 2g/3g notification toggle doesnt work for the nexus s cm7 all the way to RC4.
why are you still using RC2 when RC4 is already out?
update: nvm, i saw your original post was 2 days ago
hi thanks for replying.. I got another qns though - what's the usual procedure for changing from old RC to new RC? I just changed to RC3 and RC4 is released, and I did a full wipe and restored using titanium backup.
Can I not wipe data? just cache, dalvik cache? and do I use fix permissions before or after the flash?
I have had a Nexus S 4G for about 2 months now, and earlier today, the 4G functionality just suddenly stopped working. It was working fine, and the connection dropped, so I went into the settings to reconnect, and now it just stays on "Initializing".
I was running the 8/31 nightly build of CM7 at the time.
I have tried the following, to no avail:
Reboot
Flash a different CM7 build
Update Profile/PRL
Wipe cache/dalvik cache
Nandroid backup, full wipe, flash stock ROM
At first I thought it might be a problem with Sprint, but my sister said 4G works just fine on her Evo, so I'm thinking it's a problem with my phone.
Does anyone have any suggestions as to what I could do to fix this, or should I just return it to Sprint and exchange it? I've had it for less than 90 days so it should still be under warranty.
Is your sister at the same location?

Yes she is.
Based on what you have said, there isn't anything that should have caused 4g to stop working. I would take it to Sprint and see what they say. Unrooted of course

Update on the situation...
In preparation for returning it to Sprint, I "unrooted" it following instructions I found on AndroidCenteral (basically downloading the GRJ22 build images and flashing those via fastboot). Strangely enough, that fixed the issue.
I've now rooted it again and am back on CM7 with no problems. Just to ensure the problem wasn't a file in the backup, I'm reinstalling everything rather than restoring a backup.
Still have no clue what the problem was, but it's working now.

I'm fairly new to ROMs (this is my second). I have followed the instructions and successfully installed the ROM, modem, and update.
2 questions:
1) Wifi does not work (will not turn on). I had wifi problems on my last ROM. I have reinstalled this ROM numerous times today thinking something must have failed since wifi does not work. This seems to be unique to me since I can't find anything in the thread regarding wifi problems. Any suggestions?
I've gone so far as to use darkside superwipe as suggested in a different thread. Still can't get wifi to turn on (just sits with "Turning Wi-Fi on..." message on screen). Never errors out, just stays like that.
2) ROM Manager: Fix permissions fails. I get the following error when I select fix permissions: "An error occurred while attempting to run privileged commands!" Any suggestions?
Thanks so much for the help!
You should post your question in the ROM thread. The developer (seanscreamz) or one of the other testers will see it and be able to address your problem and help you out.
I can't post in the Dev section yet. 6 more posts and I will ask there.
starting over...
Ok, I figured I might as well make sure that my wifi woes are not a hardware issue. I've reverted back to stock Skyrocket OS to make sure wifi is available and working in stock form.
Following this link http://forum.xda-developers.com/showthread.php?t=1342348, I reverted to stock and I can confirm that wifi works in stock form.
I've also reformatted my sd card in case there is any chance a corruption on it would cause my problems.
Now going to reinstall SkyICS...

Are you on CWM touch?
have you went into the busybox app and clicked install?
wifi broken again
I have followed these instructions here http://forum.xda-developers.com/showthread.php?t=1321582 to regain root. After getting root, I installed ROM Manager and selected "Fix Permissions". On reboot, I lost the ability to connect via wifi.
Did I miss a step?
Thanks again for holding a n00b's hand!

john: I'm sure you mean well, but I don't know what your intent was with your posted link.
crazyD: digging your avatar. I'm currently trying to decide between a G26 and XD9sc...
btw, installed and ran busybox. not sure what it did for me. I also updated ROM manager to latest. Accidentally initiated a backup from ROM manager. Will see if wifi is back after that has completed.
Edit: wifi still errors, won't connect. I'm not clear what steps I may have missed or screwed up between being stock to rooted. I will revert back to stock again and try again...
Are you running juice defender? Its giving me problems with my wifi connection!
Sent from my SAMSUNG-SGH-I727 using xda premium
I'm not running Juice Defender. At this point, I'm trying to revert back to stock form again with working wifi.
Edit: ok, reverted back to stock by doing the following
1) reboot into CWM recovery
2) factory reset x3
3) clear cache x3
4) format system x3
5) clear dalvik x3
6) format emmc x3
7) restart and pull battery
8) boot into download mode
9) push stock tar (k0kane) via Odin3 v1.85
I now have wifi again!
So now I get to try to get back to SU and CWM without losing wifi...wish me luck.
still have wifi!
OK, rooted and CWM installed. I still have wifi, which is good. I'm afraid to select 'Fix Permissions' for fear that will break my wifi.
I'm going to install Sky ICS now and see what happens.
sky ics and wifi!
OK, It took a few attempts, but I now have SKY ICS installed and wifi is still working.
I've installed the base ROM and the modem...not the updated yet. My download speeds are terrible, but at least I have wifi. I think the data speeds get better on the update.
Sean's instructions say to let the phone "cache and settle". I have no idea what that means...so will try to wait 10 minutes or so before installing the update.

My uneducated guess with the data speeds is the modem for UCLE2. I haven't had the chance to go to LTE on SKYICS yet, but data is definitely slower on "4g" networks.

quick update
Here is a quick update:
I spent some time redownloading all my apps and in general setting up the phone. I then ran the SKY-ICS update. Everything seemed to be working great.
As an added bonus, the email app in SKY-ICS syncs with my employer's exchange server! Which is so awesome. The stock ROM, and the last gingerbread ROM I had on the Skyrocket would not connect to our exchange server. I was very pleasantly surprised by that functionality.
I then lost wifi again. Wifi seems to be unpredictable and I'm not sure if it is hardware or software related. I again have wifi this morning, but didn't for the last two days. Also, my phone won't restart, it appears to get stuck in a powerdown state.The haptic buttons stay lit, but the screen is blank. I have to pull the battery to get it to restart.
But overall, I'm very happy with the performance and functionality of SKY-ICS. I will do some digging on the restart problem.
It started I think after I put the 1st JB TW ROM on my phone (eg Incubus). Since then, every time I try out any AOSP/AOKP based ROM I lose WiFi.
Wipe and format everything (data, cache, dalvik). Install AOSP/AOKP ROM, do the initial setup, get WiFi working and then after 1st reboot -> no WiFi. I tried many ROMs based on the above platform. Same thing.
If I toggle the wifi on/off/on some times I get the wifi back but just until the next reboot. Sometimes when I try to toggle the wifi screen freezes.
I odined back to stock. Unrooted and locked. I rooted and unlocked and right away I reinstalled a CM10. Same problem.
When that happens there is no wifi network found and scan finds nothing (i have many netorks around me). It is like the wifi service is not present.
I tried different kernels and different radios. No go.
All the TW stock ROMs (ICS or JB) work fine.
Any idea? Did you hear about this anywhere?
Thanks for your help.

The phone wouldn't boot into the rom if they were rooted but had a locked bootloader.

Try wiping System before flashing AOKP as well. Wipe them a few times just to be sure. Im thinking that possibly recovery doesnt always wipe like it should but im not sure.
I did it.I tried too many times not to get it right at least 1 time.

have you tried the official cm10 m1 release?
I tried the last CM10 from Sep the 23 rd.I don't know which version is that.
Sent from my SCH-I535 using Tapatalk 2
Well, I have news. Problem not solved but something new came up.
I had a nand of an official cm10 from Sep the 9th. I recovered and voila the wifi works perfect. More than that. I dirty flashed the nightlie from today and everything works fine
I then wiped and format again everything and flashed the CM10 from today. WiFi lost again after 1-3 reboots.
By the way if I reboot after losing wifi next time I get a screen with activating which stays there forever. Also my phone no and MIN are gone.
I recovered them but the wifi is still gone.
I live in Ca so I'm in roaming if this is of some importancce.
Can somebody mimic this? Fresh install of CM10 official and then reboot.
It does the same for me for any AOSP AOKP JB based.
I have a netgear router that provides wifi service on 2.4 and 5 Ghz on both bands 20 and 40 Mhz. The SSIDs have different names.
I specified already that when that happen I cannot see any other wifi around me and there are many.
Guys I've tried searching and tried damn near anything I can think of/find here on XDA and other sites.
Over the weekend I got a little sick of my GPS not locking on my Verizon Samsung Galaxy S3 SCH-I535. I was running CleanRom 7 and I believe I was on MB1 - I could be wrong on the basebad that I was on.
Anyways, after doing my normal reading to see what the latest and greatest things going on are I decided I wanted to do a complete wipe like I'd done in the past, update to MF1 firmware, update my radio to ML1, then put a fresh install of CleamRom 7 on there.
So I used to did a format of my external SD then a factory wipe/reset & cache wipe in CWR. I then went directly into Odin mode (Home Button/Volume Down/Power) and flashed the root66_VZW_I535VRBMA2.7z from this thread. I installed EzUnlocker and RomManager. I unlocked the phone, then flashed CWR. I first did a factory wipe/reset, I then flashed the MF1 firmware, followed by the ML1 radio, and finally Clean Rom 7.
Everything was fine except my 4G LTE would not turn on - 3G works fine but no 4G LTE. I've tried everything I could possibly think of. I've flashed to the prerooted MA2 linked above in Odin. I've tried the 2-3 suggestions in this thread, I've tried making my own APN settings, I've tried the thread which has links for people who are returning their phone to Verizon (plain jane stock). Nothing. All of those bring me the same result: Everything works perfectly fine, but the 4G LTE never shows up. It doesn't matter where I am - I know it is not a network outtage as people in the office have no issues and I always have a connection here and at home.
I've already ordered a new SIM card which should show up tomorrow but did I miss anything? I tried everything I could think of. As of right now I'm back at square one where I'd gone back to MA2, flashed MF1 + ML2 firmware, and back on Clean Rom 7. Stuck with 3G. Any suggestions?
Thanks!
Just Odin flashed the VRALG1 4.0 ICS to bring it back to stock found here in Section 5: http://forum.xda-developers.com/showthread.php?t=1762709. Still no luck.
Am I correct in saying when flashing that it is also flashing the modem/firmware? I want to make sure I'm not missing anything.
I had the same problem not too long ago. My issue was the PRL usually 4G PRL starts with 15xxx but if you go into settings-->about phone-->status you should check to see whether it is a 15xxx or 3xxxx. If the latter a new sim card should fix it right up.
