[Q] Losing All Data Connection - Focus General

I'm now on my 2nd Focus because of this problem. 1st off, I do have an SD card in there but have not had any restart or any problems which seem to be due to the card.
I had the first Focus for about 3 weeks when all of a sudden it wouldn't connect to any cellular data. No EDGE or 3G. It would connect to WiFi and I could still make/receive calls and texts. But no internet or MMS. So I chatted with AT&T. End result: restore phone. I restored the phone WITH the same SD card in it and it worked fine...until the next day. Same problem, lost all cellular data connections. So then I chatted with Samsung. They suggested it was due to some 3rd party apps I installed (which I though was BS). So I ended up going into the AT&T store and they gave me a new one.
So I've had the 2nd Focus for about a week now and everything was working perfectly fine (with the same SD card in it). But about an hour ago, I lost all cellular data AGAIN! Restarted, toggled data connection off then on again, but still won't connect.
Could this problem really be caused by the SD card (as AT&T said?) I just don't see how an SD card can mess up cellular data. I know it does cause performance problems for some people, but cutting off data?

I guess nobody else is having this problem?
I went ahead and restored my phone again since I couldn't live without 3G connection. Still don't understand what's causing the problem though.

Obviously, you've tried removing the SD card? AT&T and M$ have yet to announce any compatible cards, officially. People have reported issues with the cards up to several days after installing them.

When I remove the SD card without restoring it just reverts back to a new install (since it can't see some of the data on the card I'm guessing) and the 3G works. I put the SD card back in and all my data is back but the 3G or any cellular data connection is gone again.
After restoring it this last time, I get 3G back (as usual) with the SD card still installed and have had 3G since I restored it.
It just seems like I'm the only person having problems with my cellular connection and the SD card, and I don't understand how the SD card can affect that. I understand loss of data or performance issues but not loss of 3G...
And as far as when I usually lose 3G, I have had info saved on the SD card for days before. Each time I've restored with the SD card in I sync all my music back to it and it definitely rolls over to the SD card. I haven't put anything on it this time to see if it will lose connection within a week like it's done before.

Yeah, it's tough to imagine a link between the SD card and the data connection, but, clearly there is. It may be in the manner that WP7 addresses the memory. It treats it as one large drive and, perhaps, after the hard reset some of the system data that deals with the data connection gets written onto the card?
Who knows? Pretty strange. It'll be interesting to see what happens now.

Thought it was time for an update on the situation...
It happened again and I had to restore the phone 1 more time a week or less after my last post. I did leave the SD card in as I normally do. The only difference was I didn't put ALL my music when I synced it (all my music adds up to well over 8GB). Instead I only put a little to where the total space taken was far less than 8GB. As I kept installing apps, taking pics/vids, blah blah blah it is now at the 8GB mark. There is a little noticeable lag now, but nothing unbearable at all. What hasn't happened (yet) is the loss of cellular data.
I'm hoping it doesn't do it again, or the upcoming update will address some SD card issues as well as copy paste. *crosses fingers*

considering it keeps happening and the 1 mainstay is the sd card....id try it without the card.... if it runs smooth...its the card.... if it screws up its something else... just too simple not to try... from what ive read, sd cards have caused a wide variety of problems, from just reboots to the extreme of bricking phones....
you havent even mentioned what brand and class card it is... it could be one of the unstable ones... if so theres your answer...

It's a Kingston 16GB Class 4, so it's confirmed working. It does seem the SD card is the problem, but (1) I don't get how the SD card can cause cellular data failure and (2) why am I the only one that is having the problem? (at least it seems like I'm the only one having a problem with losing cellular data)

well just might be a bad card... not everything that makes the shelf is perfect...
as for the why.. like i said before , there are a variety of problems... just not restarts and losing data... ive seen locking in airplane mode...ive seen bricking...etc
like i said take it out and try it.. its the only way to be sure... if it is.. try another card format the phone... put the new card in and format it 2 times and go from there....
"definition of insanity.. repeating the same action over and over again, expecting a different result..."

I don't have any card at all, but my focus also losing all data connection. It disconnects from network during switching between several cell towers. I need to reset my phone several times during my travel from home to work. It looses connection always in the same place

I'm having the same problem, the data connection works fine but there're times when it says it's connected but it can't download or upload anything, the only way to fix this is by turning off and on the phone and then the data connection works again. Not even the ON/OFF switch for data in settings fix the problem.
I also have problems with the signal in general, sometimes it loses connection to my service provider and after some seconds it finds the service again, maybe a problem with the radio?
Samsung Focus: No memory card installed, using it in Venezuela (Movistar), 3G/E data service.
I already reported this issue to the WP Support Forums, I think they're investigating the problem because I haven't had any feedback since the last time more than a week ago, here it is:
http://social.answers.microsoft.com...7/thread/b5928f07-c817-4096-9e9f-21d3088e8c2d
If somebody has this problem feel free to vote for my post to let them notice that it's not an one-person problem

Same issue
I am on Fido/Rogers in Canada and get the same problem from time to time, no SD card installed.
In my case, it happens after I lose signal for a while, like garage or no signal area...When I get a signal back, the data portion just won't connect, even though I can make and receive calls and my phone displays 3G.
Reboot takes care of it.

Just found this thread. I've been having this issue for the past two days. Have never installed an SD card in my Focus. I tried the HSUPA hack a few days ago. I thought that was the cause. So I asked for help to undo the hack.

I've only had my Focus for a couple of days.
I was experiencing a lost of data connection eariler today. I think it's to do with your location/network provider.
On my X1, I use to turn flight mode on and off to fix the problem - forcing the phone to reconnect.
Sometimes the signal is GPRS and other times 3G.

How many of you experiencing this are using the Facebook app? I was having the problem today (it started this morning) and after uninstalling the FB app (where i was noticing the problem most) and a soft reset, I'm not seeming to have the problem.

So now that I think about it, when i wasn't receiving data, the phone showed full signal, even though in my office i usually get 2 bars. After the uninstall and soft reset, im now showing the 2 bars. No idea if it was causing this, but seems a strange thing to have happen.

i do have the same problem. deactvating data connection and activating again doesnt work. You dont need to restore phone to make it work again, just go to settings -> cellular -> network selection ... remove automatic and wait till it finishes searching..select you operator or automatic again it should reset your connection settings and 3g/edge should work again.
mine is an unlocked AT&T might be a problem with the unlocking mecanism if you guys also using unlocked phones.
not sure how to solve it yet.

Never used Facebook App. Did notice when it happened today, that after I close IE I had 7 yahoo emails. I'm wondering if the limited multi-tasking carries over to data. When the phone is syncing, maybe it shuts other connections down.

serious 3G/EDGE issues with my G1

I have a rooted G1, iam running JF 1.42 RC33, i also have RC33 Radio.
i live in Chicago in a place where the 3G coverage is pretty good. in fact a month ago i was having perfect reception on my G1.
recently; i am having many issues with the data link (3G, EDGE)
simply, the phone does not pick the data link properly, and even if connected, it might drop the connection.
sometimes i have to go to settings, wireless, mobile networks, and click on "use 2G only" a couple of times to trigger the phone to connect... it will drop the connection when it goes to sleep !!!!
i have noticed that many times when the phone sleeps, it does not switch properly between the wifi and 3G [or EDGE], so i dont get my emails.
sometimes a reboot solves the problem, and some times it does not
i tried to flash the radio image again,,,, it didnt solve the problem.
any help will be highly appreciated.
If you've tried to reflash you radio and the results are the same it may not be your phone. It may be the network itself. You should call TMo to see if they have any issues in your area. About a month ago half the country went out for also half a day. It's rare but it happens. If no one else is having issues then it's possible the problem would be with the phone. You could try a wipe and/or reflash but it probably won't make any difference since it sounds like the radio (which you already tried flashing). Maybe also try checking to see if turning off data roaming will make any difference.
thank you for your response:
iam having this issue since a couple of weeks,, and i dont think it is a network issue.
i have tried to disable/enable data roaming,,,, it didnt help.
am i left to a "wipe" only.. ????
well you can give that a try and if that doesnt solve your problems then it may actually be a defect with your phone. also... ive had issues that my phone would lose data and voice even while i was on the phone. it would just disconnect then say no service. the problem wasnt my phone though... it was my sim card. if that sounds more like your problem you can get a new one for about $20 through a tmobile store.
i didnt encounter any voice call drop issues.
when i wipe, i will need to reflash everything, right?
I live in the chicago area as well and my edge/3g has been off and on like crazy over the past 4 or 5 days. I will look at my phone and it won't have an E or 3G. I'm running jv1.42rc33 with apps and caches to sd card. I'm not sure if its a network problem or my phone itself.
So you both live in the Chicago and are having issues with 3G/Edge and you doubt that it's a network problem??? I hope you didn't do your wipe yet.
I'd call T-Mobile and ask to speak with their data support (Tier 3) group and verify that it's a problem with your handsets before you do anything (like reflash, wipe, etc).
i live in chicago as well.
T-Mobile was/is having 3g network issues. T-Mobile where not aware of the issues. They say they are on the issue to solving it. :

I didn't explain myself well there. I'm under the impression it is a network problem. I learned my lesson last time there was an outage. I did like three wipes in four days thinking it was my phone.
It isn't you - my 3G (also Chicagoland) has been up and down since Wednesday. It is completely down again this morning. All day yesterday it was probably up for no more than an hour.
F'ing T-Mobile made me wipe my phone, then drive to the local store to get a new SIM, and they refused to acknowledge that it was a network issue. The sales rep at the T-Mobile store was having the same issue.

DOH! That sucks! LOL. If you're referring to the outage that we had about a month ago I took the liberty of posting a thread on here warning people not to wipe because they might not be able to sign in because of the network issues. There were so many that did and I was almost one of them myself until I wised up and decided to call first.
hello guys,,, thanks for everybody who in contributing in this thread.
i can see iam not the only one having issues in Chicago, t-mobile said they had no problems,,,,
what makes me tend to believe them is sometimes if i play with the phone the 3G shows up,
this is an experiment for you to try (it worked for me):
enable tethering using the open source gui, then disable it again.... 3G shows up !!!! even if you enable wifi... the phone will switch properly between wifi and 3G (when sleeping).
it worked for me last night and is still working now.
if you guys try it and it works,, this means t-mo has no problem,,, and we need to figure out what is wrong with the combination/configuration we have...

i just called t-mo and they told me to turn off the phone, take the battery out, put it back on..... and it worked,
now it is working!!!!!

my location doesnt update, weather, google maps, bing, etc

searched the forums with little info about my situation, other than that it seems to be happening to a handful of others.
havnt changed any settings or added apps or anything to my phone for several weeks if not months. i am using the cell evo v1 rom. 2.11.50.20 radio. i dont have a proxy server running.
for the last 2-3 days my location has only updated itself once. google maps cant find me, as well as bing. manual update does nothing. soft reset does nothing. wifi connect does nothing. i can get on the internet, sms, mms, etc etc.
i read on tmonews.com that tmobile was turning on HSPA+ in my region in the last couple days, along with 18 or so cities around the US, can this have something to do with my problem?
not sure what else to do...cant find any info.
thanks
I'm having this problem now as well. Been working on it for a couple days. T-Mo has had HSPDA+ here in St. Louis since before I got my HD2, so I don't think it's due to them adding it to your region.
Strange things I've noticed so far:
It works if Wifi is on, but not connected to a network.
It works if you are connected through EDGE, but not 3G or H.
The AGPS server IP address in the registry is a private network address: 10.something. If someone with a stock TMOUS rom can look in /HKLM/HTC/SUPD AGPS/ for the Server IP key and post the contents, I'd like to know if it's the same.
These issues are the same as everyone with different devices has been having for a while now, but the older phones with the issue seem to work in some areas without the wifi and edge workarounds, and not others. Mine so far works nowhere without the workarounds.
Try going into the manila slider and on the weather tab press menu > Enable my location
^ that isn't even an option for me on the manila slider anymore for some reason. I disabled the gsm and ran on edge and it was able to locate. as soon as turned gsm back on it wouldn't do it again.
bump, anyone?
Smartass answer in 3...2...1...
Maybe you should move to Denver. Colorado is beautiful this time of year.
Kidding aside, how about trying a hard reset?
from what i've seen on threads somewhat related to this, hard reset is a 50/50 shot. if i'm going do a hard reset where i would have to redo all of my settings and such, i'm just going to wait until the new version of the cell evo rom comes out. which is supposed to be soon.
i really dont understand what would cause this to suddenly happen. especially since it still works on edge. i tried wifi once and it didnt work, but i think i had my network connection still on. but regardless, this is pretty rediculous.
If you've traveled anywhere, your radio may be 'stuck' on a distant tower. This has happened on a couple of our phones and the tmo folks had to do a push/release/unstick type of signal to the phone. May be worth a try.
^ok, i called tmo tech support. mentioned about the possibility of sending me a reset signal, she said that was a possible scenario, but she was pretty confident that it was because my sim card is an older model sim card. claims that the sim card in my phone wasnt designed for 3g services, and any sort of change in the network (like them adding HSPA+ like i mentioned above) could interfere with the connections. she said the fact that i could do this on edge and not 3g is a dead giveaway that the sim card is the problem.
she said they are in the process of trying to get people to go to the corporate stores and switch to the latest sims. apparently this is happening to a lot of people, but the sim should be the fix.
i guess i'll shoot up there later on after work, or tomorrow, and i will give you guys a follow up on this.

Actually that does make perfect sense, and I suspect you'll find it clears up your problem. In fact, for anybody else that finds this thread, I suggest you try that step before other alternatives like hard-reset or ROM flashing.
yep, new sim card did it guys. i would recommend anybody having any connection issues to see if your sim cards are up to date.
edit: it was working before. now its only updating on edge again. not sure what to think or do. going to wait and see what happens when the new rom I use comes out.
any other ideas on this guys? new sim card only worked for a few hours. back to only updating 'my location' on EDGE and WIFI. pretty damn annoying. thinking about calling tmo support again to see if they'd send me a 'reset signal', but with having the new sim card you'd think that it wouldnt be a factor anymore, because i'd imagine it's already been reset.
the only other thing i could think of, and thats what tmo would probably tell me to do, is a hard reset. i'm sure they wouldnt be too happy with having a flashed rom on there either (not that i would tell them anyways).
if nobody has any other ideas but a hard reset, i'm going to wait for a couple days until the new release of the cell evo rom.
thanks
Yea. That weird problem hit my second HD2. I bought one 2 weeks ago and after your post paid more attention and of course noticed my location being Denver....
I deleted all preset locations and added custom one. It updated only once, right after location was activated....
However, wife's phone HD2 which was purchased on 3-24-2010 or original release date does not have that issue, ROM was updated to 2.13 a month ago or so...
Here you go...
Two of the same phones (supposedly), with the same stock ROM, with the SIM cards acquired about 5 years ago. One shows weather update without problem, second (newer one) has that dreaded nag....
I had a similar issue where the weather would only update once then freeze and never update again. All other 15 location updated but not my location. This was normal for stock and 2 roms, then I used energy rom and it now works. huh? Go figure.
Strange...I'm in St. Louis, as well...MO, that is...and it is working fine for me.
Try downloading the HTC connection wizard. This has fixed connection issues I've had before. I know Tmo has 3 networks to choose from MMS, Data, and Internet. I beleive you want data and may be your phone is selecting Internet.

ya that didnt work. either. still does it on edge though. the cell evo rom update will hopefully be here soon, if that doesnt fix it, the i'm not sure what to do.
I also have the problem of weather for my current location not updating (and the location not updating either). I have had the phone for almost a month and it updated regularly, although I noticed an occasional lapse for an hour or two. Following the suggestion by misticninja, I switched the band to Edge and I was able to update the location and weather. When I switched back to auto (3G), the update failed. It occurred to me that when I am in my basement office at home, I get Edge, not 3G. That may be why I got updates there. But I am sure it has updated in the past at my work location where I have very good 3G. Is this an HTC problem or a T-Mobile problem?

I'm having this problem ever since Tmo announced HSPA+ (4G speeds), but my sim is only 2mo. old! Is that an old sim?
You need to have your location enabled. Go to settings tab the location and then click on enable my location.

HELP! Unable to connect to any mobile network - DHD

Hi Guys,
Wondering if anyone could help? I think I may have turned my DHD into an expensive mp3 player! I don’t seem able to connect to any mobile network Apart from that the DHD functions perfectly (working wifi/gps) - it has been working fine in the past
I can’t make/receive any calls / text message. When I try to connect to a mobile network I receive the following error:
- If I choose the network manually myself (o2 for me) I get "Your sim card does not allow a connection to this network"
- If I try going for the automatic option I get "Unable to connect to this network at this time. Please try again later."
- I'm also getting the notification every 10 minutes to "Set current time" - I don't know if this is related but I assume so since both issues started at the same time!
The problem occurred when I decide to give RCMix a go through ROM Manager. It appeared to flash fine and was running smooth and quick until I noticed a few hours later I had no mobile connection I'd done this a few times before with RC 7 and CoreDroid and hadn’t experienced an issue before.
First thing I tried was to recover to my previous setup before the flash (using ROM Manager) - the phone restored however the mobile network still remained unresponsive! ...this was the same for all my previous backups. I tried clearing cache and dalvik-cache. I even tried reformatting the phone at one point.
I know it's a fault with the phone and not the sim, I'm just not sure what. I've tried my sim card in another DHD and it worked fine. I have also tried different o2 sim, an orange, vodaphone and T-mobile sim card in my phone – all of which give the same problem.
I’ve tried resorting the phone with a few different RUU’s, and even a German one just because it was o2 branded and I’m on contract with them:
- RUU_Ace_HTC_WWE_1.32.405.6_Radio_12.28b.60.140e_26.03.02.26_M_release_155891_signed
- RUU_Ace_HTC_WWE_1.72.405.3_R_Radio_12.28e.60.140f_26.04.02.17_M2_release_161342_signed
- RUU_Ace_HTC_WWE_1.72.405.3_R2_Radio_12.28e.60.140f_26.04.02.17_M2_SF_release_163262_signed
- RUU_Ace_O2_DE_1.32.207.1_Radio_12.28a.60.140e_26.03.02.08_M_release_153755_signed
I then re-rooted the phone with the use of Visionary+.
I’ve tried turning the radio off then back on, both by switching airplane mode and by using the hidden option *#*#4636#*#* and I’ve also tried re-flashing the radio and even a different more up-to-date radio:
- Radio_12.28b.60.140e_26.03.02.26_M (original)
- Radio_12.39.60.19_26.06.04.06_M
I’ve checked out the APN and it appears to be correct for o2.
I’ve done simpler things like restarting / powering off, removing the battery, re-seating the sim, re-seating the sdcard and booting without the sdcard!
All in all I’m running low on idea’s Could anyone please help or throw some idea’s at me, it would be very much appreciated!
Thank you.

The problem occurred when I decide to give RCMix a go through ROM Manager. It appeared to flash fine and was running smooth and quick until I noticed a few hours later I had no mobile connection I'd done this a few times before with RC 7 and CoreDroid and hadn’t experienced an issue before.
First thing I tried was to recover to my previous setup before the flash (using ROM Manager) - the phone restored however the mobile network still remained unresponsive! ...this was the same for all my previous backups. I tried clearing cache and dalvik-cache. I even tried reformatting the phone at one point.
I know it's a fault with the phone and not the sim, I'm just not sure what. I've tried my sim card in another DHD and it worked fine. I have also tried different o2 sim, an orange, vodaphone and T-mobile sim card in my phone – all of which give the same problem.
I’ve tried resorting the phone with a few different RUU’s, and even a German one just because it was o2 branded and I’m on contract with them:
- RUU_Ace_HTC_WWE_1.32.405.6_Radio_12.28b.60.140e_26.03.02.26_M_release_155891_signed
- RUU_Ace_HTC_WWE_1.72.405.3_R_Radio_12.28e.60.140f_26.04.02.17_M2_release_161342_signed
- RUU_Ace_HTC_WWE_1.72.405.3_R2_Radio_12.28e.60.140f_26.04.02.17_M2_SF_release_163262_signed
- RUU_Ace_O2_DE_1.32.207.1_Radio_12.28a.60.140e_26.03.02.08_M_release_153755_signed
I then re-rooted the phone with the use of Visionary+.
I’ve tried turning the radio off then back on, both by switching airplane mode and by using the hidden option *#*#4636#*#* and I’ve also tried re-flashing the radio and even a different more up-to-date radio:
- Radio_12.28b.60.140e_26.03.02.26_M (original)
- Radio_12.39.60.19_26.06.04.06_M
I’ve checked out the APN and it appears to be correct for o2.
I’ve done simpler things like restarting / powering off, removing the battery, re-seating the sim, re-seating the sdcard and booting without the sdcard!
All in all I’m running low on idea’s Could anyone please help or throw some idea’s at me, it would be very much appreciated!
Thank you.

Did you try on your phone pad to type *#06# in order to check your IMEI?Do it and check on your phone's box that they are the same

Double check your SIM card slot to see if its clear of any debris. Other than that, there is a definite fault. Was your handset originally branded?
Sounds like a blacklisted imei.

HTC HD2 with error connecting to the network problem
I have the same problem! I bought a phone from ebay "new" and I have not been able to connect to my network AT&T. The phone has android gingerbread 2.3.2 Nand, and I have tried everything in the book to see if I can connect to the network but to no avail. I have been going on forums for the last three days, and if anything, I just want to know what is wrong with the phone. My sim works on other phones fine. There is enough signal in the area (ive always had signal where I live), and tried resetting, taking the battery off, flashing different roms, even went back to Winmo and nothing has worked yet. My IMEI on the phone was different from the one the box, but was the same on the phone as on the inside IMEI.
WHat the heck is going on? Please ideas or help!
Hi Guys,
Thanks for the quick replies...

Yes sorry I forgot to mention this part - I tried *#06# and both numbers matched on screen and under the battery hood. I also had the IMEI checked to see if it was blacklisted and it has not...

Tried clearing the slot, there is no visible signs of blockage... also I bought the handset second hand - I've never seen any branding however when I bought it the previous owner did tell me it was previously locked to vodaphone and he had rooted it so that he could use other sims cards. Which is why I orginally tried a vodaphone sim card too.
Thanks for your suggestions so far guys
Just a quick update, I've been grasping at straws and I've also tried a few more bits below, none of which have worked... I think I may have to leave this one to rest. Just wanted to let others know who may be experiencing the same issues
Matching radio and RIL as mentioned here: http://forum.xda-developers.com/showthread.php?t=1040986
Replacing the mtd0.img as mentioned here: http://forum.xda-developers.com/showthread.php?t=691639
It sounds like a fault. If it was network barred you would still receive a signal, for emergency calls. Can you return the handset to HTC for a warranty repair?

I still get a message on the lock screen saying Emergency Calls only - although admittedly I haven't tried calling the emergency services to check if it gets through.
Not being the original in-store purchaser I don't even know the age of the phone but I'm guessing probably over the 12 month warranty period, sod's law - I'll give them a ring and see what they say

My DHD was from the first batch and is still covered by warranty. How did you check to see if the IMEI was blocked?
I had a similar problem to this one. My mobile data connection gave out after my DHD's temp reached about 38 degrees while playing with it in the sun. A little while later I lost coverage completely, same as you. I tried everything, flashing ruus and re-rooting, re-s-offing, everything. Ten different ROMs, radios, kernels etc.
Eventually I gave up, figuring I had confirmed it was a hardware issue, and popped my sim in my old nokia so I had a usable phone and to get on with my life after wasting so many hours. I left the DHD with the battery removed, and ended up not coming home for a couple of days.
When I got home and decided to start playing around with the DHD again to see if I could get it working properly, I noticed the issues were gone.. I've tried to reproduce this problem out of curiosity, leaving the led light on high for a while, making the phone hot. Nothing. Since then I've flashed everything imaginable, and I've switched back and forth between two radios all week. No problems.
Strange, I'm guessing I have some form of hardware damage, but everything is running smoothly now at 1,5 GHz - no unstability of any kind.
I have done that actually! I took the battery off, and put the phone back in the box just to get on with my life. I left it sitting for a day and a half I guess, and I came back BUT unfortunately, unlike you, the problem is still there. The phone tries to look for signal, but it can't connect to the network. It does find the network and identifies it by name, but does NOT connect to it.
Sounds like a hardware fault Bob - Give it back to Rob!
or try and get HTC to fix if still in warranty?
Thanks! I thought so, too!
Hey did you solve problem?
I have had that emergency calls for 2 day,s i am waiting only. Please help.
If you find that your GPRS data connection connects but you have no GSM signal do the following
*#*#4636#*#* choose radio off and then radio on, be sure to be in a location with a STRONG GSM Signal and your phone should connect. I have had the same issue with my Desire HD and have been surviving with this workaround as nobody else seemed to know
Stiill same :S Selected networkd unavailable error
Try changing sim, or it sounds like blacklisted IMEI.
But my sim works on other phones and other sim cards work on my Huawei?
I was reading through this hoping desperately that somebody had found a solution. I had switched to Cyanogenmod recently but had GPS issues, so I tried flashing a new radio and RIL. Now I can't make any calls/texts, etc. as described here.
Tried several other radios/RILs, tried nandroid restore, tried flashing whole new ROM (LeeDroid). Still the same issue. Tried the *# codes listed here, no luck.
Please let me know if anybody has solved this one. I really don't need a paperweight right now...

[Q] Q: Connection Problems

Hi there,
I'm having serious problems with my connection settings. The phone makes calls, and can send and receive text messages and email no problem, but the network connection doesn't seem to working. I can't access the internet, my twitter program can't connect, weather won't update etc. I've hard reset, without success, as the problem still remains. My phone shows the H connection with 3 or 4 bars. Also, the problems do seem to come and go. Is it a problem with the phone, my SIM card, or the network?
Thanks,
David
Could be the sim, especially if it's a few years old.
Got a friend with a sim you can try?
Well, the SIM card is about 4 years old I think - I've had it since my previous phone. Will check with another card later, see if it helps. I do hope it is just the SIM card!
Deff worth checking,, it's not very common, but its not unheard of either. Certainly worth checking that before you start trashing your instal.

No 3g after using ICS

I have been on both ICS roms for awhile recently on Texas Ice with p8, new kernel. Lost 3g, only have 2g or wifi.
Went back to MeDroid 6.1 which was rock solid--no 3g
Back to CM7 no 3g
I did the *# method/redid apn's/called tmo/did Network Operators/flashed new radio--same as I had--.12 and also tried .08
Short of passimg, not sure what to try--don't know that passimg would do anything anyway.
I have occasionally had 3g pop up then it disappears
Sons phone has 3g, so not an area issue
Anyone have and solve this or any other ideas--this is first time I have had and not been able to resolve--yet
Ken
EDIT: Oops--meant this to be in Q&A--can it be moved--
Have you tried a complete wipe? Short of that, I'm not positive. I am running MeDroid ICS and my 3g and H are running fine. I have not tried the TexasIce flavor with the new kernel since it says it's not ready to be a daily driver.
thanks
I wiped all and restored several diff roms and reflashed a fresh ICS 6.1
At a loss atm
EDIT: Oops--meant this to be in Q&A--can it be moved--
As you seen, I have had the same problem. On evervolve's ROM it was working fine for me. I just flashed it to try it, no restore. I tried several reboots with changing the carrier settings but no luck. I noticed this on the MeDroid test ROM only so far.
try to install 4ext recovery, do a full wipe in the wipe menu, you will found it in the last option by scrolling, and try cm7 or even the stock android first, if its working we will test other things
mine started on T's rom
called tmo--no luck
almost sounds like they did something--but that makes no sense
you saw all that i did--so at a loss barring passimg--that doesn't sound like a solution
got to call it a nite--maybe it will return tomorrow--yeah right--
if you thing its your provider, try another sim card from a friend

yeah 3g or 4g its only what the cellphone signal can take. sim card should be the same (now we can find micro sim card)
4ext because I know they have a good wipe, format script that wipe everything.
otherwise, it could be your sim card. I know that sim card have a life time, mine worked only one year, and burned after that, I had to bough a new one.

I use temasek's extreme wipe 3x and still do data and all else in recovery 3x--wipe should be good--redid sdcard too with sdformatter
doesn't the carrier need to change my info if i swap or get a new sim
yeah they have to link your phone number with the new sim number in their system. if the problem is the sim card.
that's why i suggest to try another sim card, try your son's one if he have a data package. putting another sim card will only temporary have his phone number and data plan and will not change any configuration of your phone
i was going to try that, but he has a sim lock code and we don't remember what it was, so some research required first
only thing that seems odd is several people have same issue and on tmo--unless they have data on other roms--
new sim seems to have done the trick--fingers crossed--
wasn't much left to be wrong after all i did to troubleshoot last nite
phone system info shows umts:3
just have pesky voicemail icon in status bar, but no voicemails and can't get rid of it-- (FIXED)
thanks for all help guys--
ken
Well, it is not solved
Had 3g all day after new sim till I got home and got on Chrome to Phone and Chrome Beta, then no more 3g, only Edge.
Mattter of fact that is the only thing different the last two days is Chrome Beta.
Hate to get another sim just to prove theory, which I don't see how Chrome can cut out my data connection.
Back to square one--
Back to Temasek's Kang for now, but 3g seems to work on road and at work albeit low signal at work. Only edge at home. Turned off router and wifi, no help.
Son's mytouch has 4g so it must be a new location issue at my house and my phone can't deal with the lower reception or something changed on my phone's reception. Not sure--
Either way it is now workable and will test for awhile and go back on ICS, no more Chrome Beta though. I am superstitious--
