invalid sim after flashing - Sprint LG G4

hey guys, i'm new to this LG world (noob alert). I bought an LG G4 LS991 sprint a couple of days ago, and everything was working. then i tried to flash marshmallow zv9 on it, it worked but i lost signal, sms, calls, 2g, 3g everything related to the carrier (invalid sim) .
I tried reverting back to zv6 but the issue remained. the sim is working fine on other phones. ps: i live in Morocco (outside US).
i tried alsmot everything and i have one solution maybe left :
My friend has the same model and the sim is working nicely since he didn't flash it. so is there a possibility to backup his data and recover it on my phone, or just the carrier information , donnow !!! any ideas will be appreciated.
I flashed with LG up and lg flashtool, i'm not very familiar with adb.

Looks like you have to sim unlock it again. Check this post over here: http://forum.xda-developers.com/sprint-g4/general/guide-sim-unlock-t3229801

Help please?

Hello I am new to android and the lg optmius 2x (p990) is my first ever android phone. And I am having some trubles with it.
I am looking to unlock it am I able to do this by "rooting" the phone to make it sim -free? it is curently LOCKED to fido (canada).
or what is the most simple way to unlock the phone? i have bought an unlock code but i get smome sort of neckwork error when i enter it making the phone still locked.
Thank you for the help and i am sorry if this is were it would not be.
Strange that give you an error, I did it with a friend's phone and it worked perfectly! Once we bought the code and put it all went smoothly!
Yes
Yes i bought the code punched it in the phone quickley read out a message and rebooted i poped in a new sim card nothing happend tryed another one still nothing no clue why..
the phone has never had a fido sim in it could this cause a problem? or is there a way to check if the phone is unlocked by not using a new sim card?
So are you saying you can access all features of your p990 but not the cellular network? i.e. you can access wifi and run apps but cannot make or receive phone calls?
If so, it sounds to me that you might have an issue with baseband/RIL. Try installing GETRIL from Google Play and see if you have a matching RIL for your baseband. If your phone is rooted, then you can use the app to update your RIL.
Nope that did not a thing it said it was all good and i even still clicked update and install then rebooted and nothing.. i may just have to call LG on this one

LG G Flex L23 stop working after 3 months usage
Got this junk from ebay, paid more than $200 for it and it stop voice and data connections after 3 months, it suddenly won't recognize the sim card which work with it for 3 months, I suspect this phone wasn't permanently unlocked by the carrier or seller. They just unlocked it temporary and sell it to grab the money and leave. Unlocked international phone isn't trustable. Anyone have the same problem?

for me, I didn't do anything to the phone, it came out the error message 'no apn connection configer' and there isn't any way to config the apn for this model, then it cut off the data connection, and voice still work. Because the data isn't working, I reinsert the sim card, then voice dead too, a red 'x' above antenna sign, even hard reset the phone still not work, anyone can help....

hello guys. i've got a problem with my Flex. The situation is next: i've purchased it from aliexpress and the phone model was d955 and was working on JB. after a few months of using I decided to update to KK. After update it shows "no network" and IMEI is "null". when I opened the back panel I saw "L23 main(2)" written on mainboard, which means I've installed incorrect ROM. Is there any idea how to revive GSM ? I've tried installing .tot file for L23 via LG Flash tool (or something like this) but it says that my phone isn't L23, so I cannot install thos ROM . Also I cannot get root and custom recovery. any help please or link to helpful thread...

thanks for quick answer, but as I said , every application recognizes device as D955, so I cannot install any other ROM. is there any way to skip this or any instructions step-by-step how to install L23 firmware ? there are only links or maybe I am blind? )))

Your phone was detected D955. So, first you try to install original LG G FLEX D955 rom. Or try cyanogenmod of D955 and see if gsm works. Then if both don't work then it will be confirmed that your phone is L23.
If you got KitKat update on it before, then it means it is D955. Because there is no 4.4 for L23.

I'll try it tomorrow. Even if it is D955, why is it written L23 on mainboard (motherboard)? A friend of mine has a D958 with the same problem, on that mainboard are two models written - LS995 and D959. WTF???

[Q] VS980 No Longer Registers On Tmobile

Hi All,
I have a vs980 that had no problems with T-Mobile until recently. I was running Xdabbebs v2.5 for awhile and decided to upgrade to the OTA 39A debloated by micro. After I installed that, my phone will not register on the tmobile network, no voice, data, mms. I even reverted back completely to vs980 stock 11A and still the same problem. I have tried my sim card in my wifes vs980 and it works perfectly fine with T-Mobile.
I have tried both in global and GMS/UMTS mode and nothing works. My imei is there and not a bunch of zeroes and under the 39A Debloated I can see all three T-Mobiles (LTE, GSM, WCMDA) listed if I search for networks but it wont register to any of them. Anyone have any idea why the phone is doing this?
The same thing happened to me just now. I'm gonna try flashing back to stock using a kdz

Insert your sim, Turn off your phone. Leave it like that for couple hours and Turn it on.

unlocked LG L90, service disabled, how to solve this problem?

I unlocked this T-Mobil LG L90 last year, it worked fine at that time. Then the phone has been left idle for a long time. Now I find out this phone won't recognize any sim card, even a T-Mobil sim card. It keeps showing "No SIM card-Searching" or "Service Disabled". What shall I do? Please help me.
I have the same issue .....
I got it unlocked the phone from Tmobile and used it overseas and when i got back after 4+ months and put tmobile sim it doesnt recognize any more.....I checked the sim in other phone it is working fine.
How do you resolve it?
Bump, any solution? Tried with LoS from 2019 and Incipient ROM - no SIM card (there is IMEI so EFS is fine).
EDIT:
Nevermind - I am blind.
https://forum.xda-developers.com/lg-l90/development/bootstack-kk-l-l90-t3118632
PS. Now I've baseband
Tip (maybe someone will use it in the future): For D405n if you have v20c patch installed (check in Device Info, I had it with Lollipop), flash aboot version "a" (patch for version c is unavaible. It will "change" your model to D410 in Device Info.
But you need still to flash D405n BOOTSTACK, not for D410 if you want to install newer custom ROM. I've spent much time to get this to work.
