No data issue on Sprint LG G3 - Sprint LG G3

Hello!
Somedays ago, my phone was hardbricked in the QualComm PORT mode... I revived it with Boarddiag tool after shorting the pins. i succesfully reflashed stock ZV8 firmware. But after configuration, my phone could not detect my sim card. I downgraded it to ZV6 bu with no success. Again with the ZV4 but same issue. I decided to root and install TWRP. After that I installed Resurrection Remix and used and Patch to get GSM signal but since then I am not able to get mobile data work. I've tried CrDroid, Resurection Remix and Lineage 14.1 but with no success. I googled and couldn't find any working solution. This phone i s my daily driver, I can't always be on Wi-Fi.
NOTE: Before the hardbricking, I bought it with the ZV4 firmware and data and network was working fine after setting them to GSM/WCDMA. I even managed to install AOSP Extended and used for more than 1 month. But after the hardbriking, I can't have mobile data on any rom.
PLEASE HELP ME!

[Q] My Aria does not detect the network after CM9 upgrade

I have had the CM 7.0 version ported to my Aria for quite a while and have been on the lookout for the ICS version ever since. I successfully download an unofficial version

on this link. I even got it to boot, but when I installed gapps, the system went into a bootloop and I had to revert back to the previous version.
The problem is ever since I reverted, it does not detect any network. It successfully shows me the network description, but there is no signal or network detected. I have reverted and tried every possible combination but the network is still nowhere to be seen. Any suggestions would be mighty helpful.

[Q] Phone has no service

Hi everyone, I have an LG Optimus G (F180K) and I've been using it fine for the last couple years and most recently under the V30D firmware which is KitKat 4.4.2. I've flashed CM11 and MIUI on it previously but restored it to the stock rom several months ago and have stuck with it since. About a week ago I flashed MIUI again as it seemed there were new builds avaliable. The installation went fine but when the phone booted up I realized I didn't have any service and my service provider was not being recognized as it just said "No service". It did show there was a SIM card inside though. So using CWM backup I restored back to my original stock rom and realized there was still no service so I did a clean factory reset. That didn't fix the problem so I tried updating the phone with the kdz files straight from LG's servers which still didn't fix the problem. I checked my IMEI which was not broken and the phone number of my SIM card is recognized but it just always "No service". I tried reverting back to stock rom and factory reset multiple times the past week but it still won't work. Any help? Thanks

[Q] xt1023 stuck on 4.4.2

I got a moto XT1023 mono-sim that was purchased in Boston (and frankly I forgot to see what was the original firmware)
So I installed the CM11, but did not work for me because the headset did not work ..
installed again the stock rom, and none of what I tried did the phone signal work, I could upgrade to 4.4.4, but the phone signal did not work.
Until I found the ROM RETUAWS_XT1023_4.4.2_KXC20.82-15_cid9_CFC.xml.zip
(http://bit.ly/1pGmrKp)
And to re-install it, i needed to reset the phone again
And it worked, I went back to have phone sign, worked headphones!
But I cannot upgrade to 4.4.4 and consequently will not update for android 5.
Any help?
I noticed that all rom i've tested and the phone signal didn't work are _cid14_
the rom it worked on my phone, is _cid9_

There is a 4.4.4 version, does anyone know if you can work?
Because I got tired of resetting the phone and having to install all the apps again, so with unroot the phone to install improvements in battery

HTC M8 Lineage OS: no sim card detected

Hi everyone,
I own an HTC One M8 which went on bootloop a week ago. The bootloader was unlocked before that happened. I tried everything to solve the problem, even a factory reset, but didn't work.
So I tried Lineage OS. First I install the latest TWRP recovery available, then the last nightly that came out for M8, in the end the Gapps package. Finally the bootloop was over.
Now the problem is that my sim card is not recognized. No data, no calls. I tried different Lineage OS nightlies, different ROMs with Nougat, I tried to power off completely, the airplane mode, to put some tape on the back of the sim, nothing worked.
Before the bootloop, the sim was detected even if sometimes the signal come and go.
However, everytime I flash a new ROM, at the initial setting stage they recognize that my sim card is italian (which is correct).
Can anyone help?
Thanks and cheers

modem appears to not work

Hi everyone, i think during my attempts to upgrade my tablet from root marshmallow i messed or currupted the modem.
I had rooted marshmallow, then i installed twrp. I then tried to install lineage os, it went in a perpetual bootloop so i installed one of the modems for nouget. After that the bootloops stopped, but the tablet wont see the sim, and the baseband info is blank.
I also cant restore using a kdz as lgup wont recognize the device, i even tried uppercut and it sees it as unknown device, i have tried the different dll tricks without success.
does anyone have any advice?
after spending 2 days and finaly posting, was able to fix by doing a nandroid of marshmallow and flashing a marshmallow rom.
