Hi,
I got a new Vodafone Prepaid SIM card. When I turn on the data, I just get the 3G symbol, it turns to 'H', stays on for 3 seconds, turns back to '3G' and then disappears. This whole process keeps repeating every 5 seconds.
A couple of months ago, I accidentally formatted the system partition in cmw recovery and I could any signal. So, I used an old nandroid back up, restored the EFS (.bin and .md5 files) from the radio folder. After that I had no problems, even after flashing new ROMs.
May be a dumb observation, but my previous sim was a PostPaid Vodafone and the new one is Prepaid. Does this affect how the radios I restored from my Old Nandroid backup alter the way data is being connected?
Even now, the signal strength is good and I am able to make Voice calls without any problems. Its just the data connection that keeps blinking.
I searched around and found a similar T-Mobile bug where people edited the build.prop (ro.telephoney.ril.v3) and got this working for HTC phones. I tried that and it didn't work.
I've attached my build.prop here. I don't know what to do. Please help.
OK.. sorry for pressing the panic button too early. I raised a complaint with Vodafone and they refreshed my data settings (after taking their sweet time). Now I'm able to connect to Data.

Ok, so I updated my s3 to 4.1.1 but after a week of using the update, I still hadn't seen any sign of the expandable notification options. So I decided to re-install the update by flashing via Odin, which I did. After the flash, the expandable notifications still weren't available, so I instead flashed the stock firmware, hoping to update from stock and see if the problem was fixed. Unfortunately when I rebooted after the stock install, my phone would no longer connect to data, or even to the network period. I can't text, make calls, or connect to data. It shows full bars but when I try to do anything it tells me the network is unavailable.
I tried a lot of options for fixing it:
-I checked all my network settings. Data was on, I switched into and out of airplane mode, no luck.
-I tried to set my network operator by manually selecting tmobile. No luck.
-I tried re-entering T-Mobile's APN settings. No luck.
-I tried to restore from a backup I made of my 4.1.1 when it was first updated. No luck.
-I tried flashing multiple versions of stock firmware, as well as cm10. No luck.
-I checked my IMEI, it's correct.
-I flashed a few different modems. No luck.
I've run out of ideas and I can't find any other ideas in the forums. The closest I have come to getting a fix was during one instance when I was flashing stock again, I cleared my cache, dalvik cache, and did a factory reset as well as formatting my internal storage. When it did the first boot it had service for about thirty seconds. I was able to receive a few waiting text messages, and I had edge data for the remainder of the 30 second or so period. Then I lost data again. Every time I boot a notification ticks on my status bar that says "Restricted Access Changed" and before I can pull down and tap it, the notification is gone. When I try to set a Network Operator, it says something along the lines of "Unable to connect, not registered on the network." I'm stumped.
Has anybody else had this problem, and does anybody know how to fix it?
Just a guess, but perhaps T-Mobile has blocked your IMEI? Did you buy the phone off of someone or straight from T-Mobile?
Did you ever report it lost or stolen?
Only thing I can think of given your scenario.

I bought it through Costco as an authorized upgrade offer by T-Mobile. I can't imagine any reason why my IMEI would be blocked. I went to the t-mobile store yesterday and they told me that it should be working and that I should take it back to Costco and see if they can do anything for me in terms of replacement.
Problem Solved!
Apparently it was because when I got my phone they didn't give me the upgraded sim, they just cut my current one to fit the microsim slot. Go figure. This could have been solved by tmobile last night if the guy hadn't refused to help me just because I had rom manager installed on my phone. Just because I have a root program installed on my phone doesn't mean my phone got messed up playing around with root. Anyways, i updated my sim card through tmobile's phone service and I'm a happy camper now!
Hi all, sorry to troll, but I have an almost brand new HTC One V on the NTELOS (Virginia) network. After I rooted it, (using the htcdev onlock procedure), I attempted to install cyanogenmod 10 on it.
I thought that I had a good backup, but unfortunately did not notice the backup had failed due to not enough space on the sd card.
When CM10 did not proceed beyond the boot screen, I held down the power key and forced the unit off.
From that point on, any rom I install does not allow me to turn on or connect to any network (mobile or wifi).. When I check for the WIFI Mac address, it says 'unknown'. I am thinking this is a kernel issue, but each kernel I have tried either does not recognize the wifi radio, or does and crashes whenever the cell side tries to roam.
So, if anyone has a stock/good backup for this phone on the NTelos network (virgin mobile apparently has a different radio/config), I would be grateful. As now, ironically, I have a smart phone that cannot get data.
Almost a week ago now, i decided to flash a 4.2 aosp rom on my s3. After the flash i couldnt get any data over cellular network. I noticed my IMEI was 00, so i followed the steps on http://forum.xda-developers.com/showthread.php?t=1804123 to restore my IMEI. After my IMEI was restored i was able to get data that immediately dropped down to edge netowork. In my area we have no LTE with at&t but we do have hspda+ with strong signal everywhere. I eventually found http://forum.xda-developers.com/showthread.php?p=29461950#post29461950 and i have taken every step on this post, now multiple times, with no change. I have flashed back to stock with odin and tried it all again. I still have edge network only. At this point I will see 4g for at most 30 seconds after every reboot and then immediately lock into edge network. I feel defeated. I can get my phone replaced under warranty, but at that point i will be afraid to modify it anymore. If i find a fix i can feel safe using my phone unlocked/rooted because i will know how to fix it.
Please if anyone has any tips or help that i can try, let me know. Im desperate at this point.

Your solution fixed the problem. Thanks!
I also had the same identical problem,, I followed the steps by selecting "all" on all 3 , and then selecting "automatic", but it loses 4g after just a few mins.. I restored the IMEI, replaced the sim card, and everything.. We don't get LTE here but I still selected "all"...
So about 6 months ago, I decided to finally try out some custom roms on my t999 after running stock for over a year. I tried a couple of roms and stuck with cm11. Every thing was great until about 3 weeks ago. Out of nowhere, my phone randomly decides to drop connection to tmo towers. Sometimes i have bars and 4g symbol and sometimes i don't have anything. When I pull the battery and restart, I am able to connect to data, make calls, and send messages for a few minutes, but then i lose everything. Randomly throughout the day, I will get signal back for a few minutes but thats it. I flashed a touchwiz rom for now so I can use wifi calling, So that still works.
So I tried to flash a different baseband modem from DocHoliday77 and none of them worked. I also tried going back to stock following DocHoliday77s guide once again, but for some reason that does not work. I launch odin3.07, put my stock firmware in the pda section, make sure only auto reboot and F reset time are checked. I connect my phone in download mode, it is detected and i start the process. The phone restarts but gets stuck at the samsung logo screen. I have tried flashing different roms and none work.
I dont think its an imei problem because I got the phone direct form tmo with a contract.
Does anyone know what I might be doing wrong? ANY help would be greatly appreciated.
Did you factory reset after you flashed the firmware in Odin? That's the only way it will boot coming from cm.. You may just need a new sim if flashing to stock won't fix it.. And BTW T-Mobile doesn't do contracts
Hi, I have a problem with my device. Disclaimer: I'm very noob so please be patient.
I'm starting to get SIM CARD REMOVED error since i changed my network provider. My previous sim card was not LTE, just 3g and it had no problem with the device. The new sim card is LTE. It took me literally 5 days after enjoying the new network provider till my device acting weirdly.
Before changing, I upgraded to MM. Originally my device does not support LTE, but then I played with the system (sorry for bad terminologies) and make the feature available. No problem detected with old sim card.
So, I tried the old fashioned way; Hard Reset. I had the device reset twice but nothing changes. Frustrated of the constant automatic reboot, I wiped all system, delvik, cache, etc using TWRP. Then i installed CM13 and use it as my OS. It works well. I got the signal with LTE data. Realizing that the ROM does not come along with Google Play Store, i installed gapps. Soon after restarting the phone, the signal only lasts for an hour then it says " NO DATA SIM". I figured a temporary solution which is, rebooting the device after you lost the signal. It is just temporary though. The signal will once again lost.
What I have tried: 1) Locking the simcard while the phone still got its signal.
2) Changing values using this guide-> http://forum.xda-developers.com/lg-g3/help/annoying-lg-g3-problem-lte-signal-solved-t3293721
* My sim reader does not seem to be having any defect.
Any help would be greatly appreciated! Thanks!
