will upgrading to lollipop revert my unlocked lg ls980 sprint?

I unlocked my LG LS980 G2 Sprint and now use any sim of any of my country's networks. I have downloaded all the necessary files as advised by you for upgrading my unlocked LG LS980 G2 Sprint to Android 5.0.2 Lollipop based CM12 (nightly). My problem and question is: if I upgrade my unlocked LG LS980 G2 Sprint to Android 5.0.2 Lollipop based CM12 (nightly), will it still remain unlocked for me to use any sim of my choice or do I have to re-unlock it again?

Soft bricked Note 4, need to revert

While I was excited as to the prospect of installing 5.0.1 , I didn't notice the fact that apparently the SM-N910V (non-developer) doesn't take kindly to loading ROMs so now it get's stuck at black screen saying "Software Update Failed". The info at the top reads as follows:
ODIN MODE (HIGH SPEED)
PRODUCT NAME: SM-N910V
CURRENT BINARY: Samsung Official
SYSTEM STATUS: Official
REACTIVATION LOCK: OFF
QUALCOMM SECUREBOOT: ENABLE (CSB)
RP SWREV: S1, T2, R1, A2, P1
SECURE DOWNLOAD: ENABLE
UDC START

At this point, I just want to be able to get my phone back on (if at all possible). Any help is greatly appreciated.

Revert to Stock recovery.

hi all,
today morning i just got an update. when i tried to install it goes to twrp recovery. so i am unable to update. i tried flashing the update zip (copied from android/data/..../cm-bacon-7be...90510ef.zip), it fails in twrp recovery.
now some search resulted that i must go to stock recovery to update that.
i figured that i can flash stock recovery using " fastboot flash recovery recovery.img ", but i dont know which recovery to flash. and i am still wondering is it the correct method?(if yes, please take some time to link me to that recovery or just attach recovery of cyanogen).
any suggestions on how to revert to stock recovery or updating manually??

thanks!!!

ps: iam complete newbie, if you find this as duplicate or annoying or anything that prevents to answer above que. please teach me, i am ready!! :o

revert to stock issue6

I have installed unikernel on my g925t s6 edge regular edge.*
Now i need to revert to stock kernel but i can't. If i do a fresh install of the lateset build OI1 from odin the flash procedure complete succesfuly but the phone after that wont boot because it stuck at Samsung logo powered by android. And when i go to download mode Recovery mode is Samsung official and System status is custom. I tried to factory reset with recovery but nothing. I have also tried to fully wipe the phone with twrp but nothing. After i flash the official lastest build with odin the system status is still custom and the phone is stuck at Samsung logo. I have to flash this kernel again in order to boot the phone. But i need that phone works with stock kernel and stock system. I also did an efs folder wipe, which means i have flashed another efs with odin and after that imei said unknown. Than i have repair imei and have my phone back to function. But i cannot revert to stock
Any ideas ?
