Data Connectivity issues after Flashing CM10

**VESTICLE** · 11-14-2012, 09:20 AM

Hello everyone. Im still pretty new to this but I rooted my Sprint SGS III yesterday and flashed the most recent CM10 Rom to my phone. I am now having issues with my data connectivity. It will stop working and I have to reboot my phone to get it to connect again. It seems like once it stops working it wont reconnect to data until I reboot. Is this a common issue? Is there something I can do to fix this? Thanks in advance!

It's not normal. Did you do a full wipe before flashing it?

I'm using the cm 10.0.0 version and having no issues. You might want to flash again. Or even redownload the ROM.

I did a full wipe before installing the Rom. I basically went step by step through QBKing's YouTube video.

I was using CM and my Wi-Fi signal was noticeably weaker, and would drop out where it wouldn't before. I flashed back to wicked and signal was back to normal. Flashed back to CM and same thing. I'm back to Wicked now and signal isb good again, no Wi-Fi drop outs and I can take my phone further out and still be connected.

What other Rom would you recommend? Would I follow the same instructions as I would if I was flashing from my original sprint Rom?

Depends on what you want. I cannot suggest any cm or aosp roms because I just don't like them.

Thank you for all of the information. I am either going to re flash the CM10 Rom or try a different one out. My last question is do I follow the instructions in the videos just like I was flashing from a stock, rooted phone? Thanks.

If going to a completely different ROM always factory reset, wipe cache, wipe dalvik cache before flashing ROM.

Actually, it is normal. CM10 has a serious issue with the - if you move from a 4G LTE area to a 3G area you will lose data connectivity on CM10. This issue is present even in the more recent stable releases.

You can disable the 4G radio and generally not have any issues; though some users in the thread are reporting 3G dropoffs with the latest radio flashed.

So now cm and aosp fans are calling issues with their devices normal. Rather than calling them what they are...

Just because it's common and to be expected doesn't make it NOT an issue. Are you guys just trying to fool yourselves into acceptance.

**VESTICLE** · 11-15-2012, 03:02 PM

Thanks Trekkie, It all makes sense now. I turned off the LTE radio and have not had any issues since. Kind of a bummer but not really a big deal because 4g coverage sucks where I live anyway.

I absolutely love the amount of user control that CM roms afford. The level of customization and features are second to none. The thing is, is that there is always at least one issue with them that I can't put up with. Sometimes it's sms's not working right or camera issues or sound issues. This time for me it was signal strength. I updated profile and was on the most recent prl before flashing CM.

One of these days it'll work perfect for me, but I'm still waiting for that day.

Really not any more control than you have with the stock based roms. The only thing I miss on a cm rom is the hold back to kill.

You're right, I should have called it a "Known issue" :P

But yeah, it's actually killed my usage of Cyanogenmod based ROMs on this device. I've switched back to the stock ROM just simply because I got tired of the data cutting out repeatedly (say, every 30 seconds).

Googled around for this issue and here I am... Having the same issue of losing data connectivity on my CM10.1 based d2vzw.

That's a shame and it might cause me to look elsewhere for another rom for my phone.

Do you have a Sprint GS3?

Negative... d2vzw, so a Verizon one. Still have that issue though... or so I notice.

Ya, I noticed the d2vzw. That's why I asked. I figured that you either flashed the wrong rom or you came into the wrong forum. Looks like you came into the wrong forum. If you try the Verizon GS3 forums, they might be able to help you. They tend to have a better understanding of their roms than we do.
