H19 Radio semi broken after unlock and root: please help! - LG V20 Questions & Answers

Internet not working at all off of network . WiFi works so Thought it could be the apn but I returned to stick and no dice.
Phone: j10, newest modem.
History: Had a hard time rooting it after unlocking the bootloader. Easy cow'd the hell out of it till I realized it doesn't work on the new ota. I finally got it to work (root) on through the regular method. Decrypted, superusered and flashed overdrives Rom. Worked for 5 hours until I through on waze and my Internet crapped itself. I super wiped it, even the internal storage and reinstalled the Rom and still no internet but WiFi works. Then I decided to go back to stock and still borked. .
Also I flashed the new modem as well.
Any suggestions and help would be awesome

Help! phone is not picking up any cell signal!

hi,
So here's the situation. I have a Galaxy s gt-i9000m
the phone has been working great up until now...it was running stock 2.2 (rooted)...and two days ago i decided to reset my device and erase everything on it, and start anew...so after doing a factory reset, the phone was working perfectly, as it should...it worked fine yesterday too...so today i installed two apps, UNO and HD wallpapers...and after installing these two apps, my phone stopped picking up any carrier signal...so i tried restarting and still no signal. so i uninstalled the apps but still nothing...then i tried a factory hard reset, and still no signal...when the phone starts, it just says contact your cellular provider...ive tried 2 different SIM cards, and the same thing happens...the sim cards are fine, i tried them in a different phone and they work...
The phone has been unlocked, and was being used in Pakistan (on the Carrier Ufone)...
any help as to whats going on or how to fix it would be awesome...

Cellular connection not working correctly

I recently went through the steps to go to 4.4.4 NI2 and root it with this guide: http://forum.xda-developers.com/showpost.php?p=55495211&postcount=1
During that process, I noticed my cellular signal wasn't working correctly, but continued on until I finished installing Rick's ROM V19.6 with a fresh install of safestrap and fresh install of Rick's ROM. Now that I have that installed and want to actually start using my phone now, my cellular connection is hardly working at all. I reflashed the NI2 modem firmware and now I am getting 3g signal only when I should be getting 4g. My ping is also very high 1000+ms. My download speeds are also super low (0.18 mbps down/ 0.59 mbps up). Something during all this process has really messed up my cellular connection and I don't know how to fix it.
I tried flashing the NCG Modem firmware and it wasn't getting any signal at all . It was just showing the circle with a line through it. I then flash the NI2 modem firmware and am getting the behavior as described above.
I ended up going to the verizon store and it took a new sim card and factory reset to fix it. No thanks on future rooting prospects for this thing.
I feel like a factory reset alone might have done it, oh well though, glad you got it fixed.

I had factory reset it several times myself. In any case, I am glad to have it working again.

[Q] CyanogenMod 12.1 nightly on G900W8(klte) - No cellular data?? (3G/46/LTE/...)

Hello community, I searched for hours before actually posting this thread.
My device: Canadian SM-G900W8(klte)
Last stock firmware: G900W8VLU1BOC1
Carrier: Rogers
Recovery: TWRP 2.8.7.0
Two days ago, I flashed the CyanogenMod 2015-07-14 nightly build on my phone using the official guides including gapps and everything seemed to work perfectly except one thing: the phone can't connect to the cellular data service but calling and texting does work, only internet dosen't it won't connect to the 3G/4G/LTE at all.
Before flashing I of course backed up everything with TWRP including my EFS/MODEM partitions so I switched back to my stock nandroid backup because I really needed my fully working phone the next day and it was late and data worked again.
Today I gave it another shot with the 2015-07-16 nightly and the same problem is there... I verified my APN settings and everything is correct. When I first got into the APN menu there were alot of them on the list including the ones I had on my stock ROM but none was selected so I ticked the one I had before but it still dosent work, I tried all of them on the list and no result. I even verified the APN(s) exact settings with my Carrier and everything was good yet the phone still won't connect to LTE, but calls and text do work again... Another thing I did was to restore the modem/efs partition with TWRP while running cyanogen just to be sure but it didint have any effect.
I really wanna use CM because I'm disgusted and tired of TouchWiz but I'm clueless on how to make the data work I tried everything I knew and read on forums.
I have the exact same issue...same phone, same network....
Did you resolve this?

Try to delete All Useless APN setting. It resolve my problem, and I have the almost the same configuration. ( Rogers, S5, Cyanogenmod 2015-08-01 )
The only one problem that i got, sometime LTE network lost signal for 10-30 seconds. But for what I read, it a common issue with this version ( 5.1.1 )
Good Luck !
Tried all that....
Finally went to an earlier build from April....working good now!

Thanks for the suggestion. That fixed it for me, as well. I actually deleted all the APN settings and then recreated Rogers LTE (ltemobile.apn).

Nexus 6p calling issues, please help

Hello,
I have an international version Nexus 6p. While I was in Panama I accidentally removed the OS using TWRP, after rooting. I reinstalled the latest OS, TWRP, root, and used a custom ROM. I was dumb and didn't back anything up.
I couldn't make phone calls or access the internet with my phone on the network I used there, but I could with WiFi so I chalked it up to the ROM. Removed that and did a fastboot factory reset. I still couldn't make phone calls or receive them so I figured it was the network in Panama.
When I got home I still can't make or receive phone calls. I can text, and access the net but the service is very unstable. I am using cricket wireless, and I know it's not the service because the Sim was in my gf's iPhone and worked perfectly, and my friend has cricket and his is stable and works perfectly. I am running the latest Android 7.1.2 and would love some help with this issue.
I have tried flashing a new factory image, erasing modemst1 and 2 through fastboot, changing bands, using a different Sim card, factory resetting in general.
I have not tried another ROM (read somewhere that chroma would fix the issue, but don't really wanna jump back to 6.0.1 unless I have to).
Thanks for any help.
