Loss of cellular connectivity on GPE & AOSP ROMS - General Questions and Answers

Hello, I have a Verizon HTC one m8 and I've tried everything. I want to run other Roms besides sense based but cannot due to cellular connectivity issues. Can anyone help?
TIA

No 4G & Spotty 3G on CM10

Hi All,
I'm having issues with my 4G on the latest nightly of CM10. It's giving me no connection to the 4G network and when it says it's connected to 3G it's still greyed out so I have no data network available to me! Since I wiped the cache's to upgrade from the 8/20 nightly do I have to do any network calibration? Should I try flashing one of the other radios here:

Thanks
I've seen this a lot on AOSP ROMS and unfortunately CM doesn't get a free pass. I'm sure it'll get better as development continues. Maybe try out a 4.0.4 based ROM. (Synergy)

It's weird though, when I first flashed the rom it was connecting to 4g EVERY time it had a signal. Now i'm lucky to get 3G...

Data doesn't work, mms does. Not sure what to do

My wife has my old One S. Ever since I had it with custom roms installed the data connection just refused to work. I've tried different radios, kernels, and build prop edits.
What info do I need to provide to help diagnose the problem?

[Q] crespo vs crespo4g

I have an deactivated Nexus S 4G that I am testing roms on. Can I use standard Nexus S roms on it. I do not need use of the cellular radios.

It's more than just radios... There are other small differences that cause compatibilities to be different..

You'd need to swap the boot.img inside the crespo ROM with one from the crespo4g in order for it to boot, don't expect everything t work flawlessly though, and don't expect to get a working kitkat ROM either lol

[Q] Mahdi ROm 3G/2G Signal Keeps Dropping

Hi Can anyone help,
I updated my cynognemod 11s to mahdi 2.7 bacon it keeps dropping phone signal. my model is A0001 and live in australia. Does that matter.
Regards

Its not just Mahdi ROM. It has to do with your baseband and radio. A lot of people including myself are having this issue.

AT&T LG G2 D800 baseband issue

Hi everyone!
I used my unlocked LG G2 with a T-Mobile SIM card for a few days with the stock rom and the radio signal was fine. But then as it looked terrible and the performance was not so good, I decided to install the Cyanogenmod 12 nightly. After a couple hours, I realized the gps and gyroscope sensors wouldn't work, something widely known about this cell phone. I found out that flashing a different baseband would fix it, and after I did that the sensors started working again, but the signal was always intermittent and my 3g would suck.
Then I tried to flash the original baseband again because I'd rather not to rotate it than have a bad connection, however, it didn't work: the sensors don't work and the signal is still terrible.
I ran an app called Network Signal on my friend's cell phone, which is the same as mine with the stock rom. There's a tab called SERVICE'S ADVANCED that says OK on his and NO SERVICE on mine.
Does anyone have any solution or advice? Attached is my information on baseband and rom.
Thank you!!!

The problem is that you didn't know that Lollipop ROMs need the modem from JB 10C or 10O. Your modem is the KK version from 20C.
As for the signal I'm not sure what to suggest because the performance is bad in that regard. Sometimes it will drop to 2G in areas with strong LTE or Hspa+. I'm also T-mobile.

I tried installing those but they didn't work either. Would you have the links? Maybe I downloaded the wrong ones.
Also, are you using lollipop on your g2 right now?

This is the list I found: downloads. codefi.re/autoprime/LG/LG_G2/G2_modems (delete the space between downloads. and codefi)
I tried the 10D and 10O, but there's no 10C for the D800.

Sorry, forgot my charger at home & couldn't respond back. Anyway, it's 10D and not 10C, I keep getting all the modems mixed up. I actually reverted back to JB because I'm giving the phone to someone that doesn't like LP. Before I had vanir (LP) with the JB modem 10O.

If the JB & KK modems don't fix your issue, then something is wrong with your G2, or those features are currently broken in that CM12 nightly. One thing you could try is returning to stock, then root after going back to the official ATT firmware. Trying another ROM besides cm would be s good idea too.
Would you mind running this app called Network Signal and sending me a screenshot? I want to compare yours to mine. You just have to swipe left to open the menu and then click Signal Check:

Would you mind using the one from the link? No problem if you can't, but there's a specific option that I wanted to compare.

See, that's my problem. The textbox "Service Advanced" says FAIL and I think that's due to wrong modem. I'll try to go back to stock and try something else. You're using the baseband that ends with 84, right?

No, 34. I haven't changed anything after returning to 4.2.2.
