LG G4 ZVB

I got a phone for a deal from a friend today in hopes to unlock it to use with my Cricket Sim card. Well i am new to all of this but notice its running Android 6.0 or ZVB and see its a Death Trap.... ????
Does this mean the phone is not able to be rooted and Carrier unlocked since its ZVB ?

please help guys

Unfortunately there is an anti roll back mechanism in ZVB, meaning you will not be able to go back to ZVA, ZV9 nor ZV6 which is the version I know it can be rooted. You may find more information here. Now Sprint can unlock it for free, you just need an account with them (cell number) and they gladly help you at no expenses.

I called Sprintbonce i read about the ZVB junk and they required a security pin
Do you kniw if it must be a Sprint customer to get help withbit or has to be the recent user ?

Yes, you will of course need the original owner, which if you did buy it from a friend, should be nbd.

You can use basic flasher/dfs to get the spc and unlock.

I flashed mellow mallow rom as i was in zvb already from OTA. I turned on airplane mode after i turned it off radio didnt turn on anymore. Tried alot of things still nothing. Sprint lock phone info so i cant turn manually. It also says unable to control device radio. So i flashed global MM and now it does not ask for my pin. I thought maybe i can use some tool or a comand to force turn it on. Maybe its sprint blocking my phone even thought ESN check online seems clear. any idea ?

TOT back to Sprint ZVB factory firmware?

Yes, I've tried that method it, it still won't allow me to enter the bootloader. I've tried to enter recovery mode as well but i can't either.
It seems very strange. Its like it's locked in some way.
This my model number

is your phone a h811 and not a frrankenphone .. means it says h811 but actual model maybe another . thats reason maybe you cant unlock.

It's definitely a h811, it says it on the back of the phone, underneath the cover.
But I did buy it unlocked so I could use my sim card.
Maybe that is the reason, but I really don't know.?

thers 2 types of unlocked.. sim carrier . means you other sim not tmobile and... bootloader unlocked to flash custtom roms and kernels ect...
just in case you have doubts.
you want to make sure is a h811.. open up phone and take motherboard and read model number on motherboard plaque.

if you bought cause you wanted h811 i would ask for refund.. they are refurbished phones. they edit software.. so now if you going to keep flash h810 stuff... yes it can be rooted. with rooted imaged pushed in a command.

only thing that comes to my mind is that your phone is not a h811......
plastic and software says it is. but maybe your motherboard could be h810...
if you cant find a fix for this.. open it up search for dissasembled video of LG G4 and take motherboard out physically.
and read the plaque variant model... maybe its not h811 thats why it might say its locked..
or return it.

i guess.. since probably you had a h810 rom but software was edited to read as h811.
maybe maybe not..

Is your's a dual sim model? I've heard that can be an issue as I think there are very few roms that support dual sim. Otherwise, yes, should be able to flash whatever you want, except of course t-mobile rom.
the lgv35 file works on the vv40 because they have the same chip; sdm845. You'll also see a v35_engineering_abl bootloader mentioned, it too works on the v40, but it won't actually boot the device unless you're running Pie.
One thing about the v40, with the firehose available, it's pretty hard to brick.
cheers
