H950 blocked

Hi guys, I bought the lg g flex 2 h950 att version and when i put another sim card it asked me to put a code, and i thought it was my sim card code. I put it like 10 times and a message appeared and said that the phone was permanently locked out.
I did a reset, a hard reset in recovery mode and it did not work, i also saw that i can reinstall firmware, but my version is 5.1.1 of android and if i do it my phone will brick. So what can i do? Please i have no idea

Hi men, I could fix it, i took it to a technician and he told me that was locked by at&t, of course i knew that, and that there was a server on the internet that could free that lock. I paid like 20$ on that page, honestly i don`t know what page is it but it was the solution, not flashing or even installing a new firmware

How to downgrade from Nougat 7 to Marshmellow 6.0.1

How to downgrade from Nougat 7 to Marshmellow 6.0.1​
If you want to save the thing's you currently have on your device, then do a backup using Samsung Smart-Switch.. Because everything WILL be deleted!
First open settings and go to about phone then tap 6 to 7 times on the Build Number until you see developer mode activated. Then go back to the settings list and look for Developer Options and tap it. Now look for OEM unlock and turn it on. This step is important and NEEDS to be done or you'll have problems later, not kidding!! In the same list as OEM unlock, look for, and make sure USB Debugging is on.. Make sure you have no accounts on the phone before starting this( if you're not going to enable OEM unlock) delete all of them especially Google accounts! If you don't do this you can be locked out for 72 hours! Delete any fingerprints and lock screen pins also!! (Create your backup using Samsung Smart Switch or KIES or whichever you want BEFORE deleting any accounts!! Meaning LEAVE your Google account on the phone until your backup is FINISHED and THEN you can remove it.)
On a Windows desktop download odin(unless you already have it) and download firmware number N920VVRS3BPI1 from my Android File Host here ----> N920VVRS3BPI1 onto your windows desktop. If you use any other firmware besides the one I'm posting, it may or may not work so I suggest you use this one first.
After downloading the firmware shut your phone off (Did you make your backup and save your stuff FIRST? If not DON'T start this) and then put it into download mode by holding the volume down button, the home button and the power button at the same exact time (all 3 together). When the screen turns on immediately let go of the buttons and press the volume up button to continue. At this point odin should be open on your Windows computer, connect the phone and when you see it says added on odin you need to go into options and uncheck auto reboot, you NEED to do this! This is the only thing you SHOULD be ticking in these settings, do not tick on re-partition or anything else. Then go back and tap AP and select the firmware N920VVRS3BPI1 that you downloaded (extract it 1 time on your PC first) and after it verifies (odin might crash and say it's not responding on some systems, just leave it be it will finish and work again) then tap start and let it finish. When odin finally says PASS and you see successful 1/ failed 0 then disconnect the phone and immediately press and hold the volume down button and power button at the same time and when the screen comes back on select factory reset and after its finished the phone will reboot on it's own and you're done and booting back to Marshmallow 6.0.1.
If you don't follow these steps correctly you're liable to get stuck or something else and your phone is not my responsibility if you do something wrong and it doesn't work it's because you made the conscious decision to do it likely you'll have no problem with this if you follow directions!!! I did all the testing on my own Samsung Galaxy Note 5 Verizon model before posting this and did it several times to be sure it worked correctly.​

can you help me please with Note 5
can you help me please with Note 5
I have bought a Samsung note 5 from Dubai and it is working on my sim card at Egypt internationally for 5 months without problem.
I discovered that it is a Verizon modified to work internationally!!!.
However I was going to sell it and i did a factory hard reset to delete my personal data then the night mare began.
First of all the phone stuck at the set screen of accepting the terms and never reached the point where i can input my google email and password, whenever I accept the terms it get back to the first screen of language selection.
then i tired some pc applications to bypass the FRP lock but one of them made an uncomplete download which give an error and i can only enter the odin download mode nothing else ??
My question now is will your firmware N920VVRS3BPI1 solve this problem and let me use my local/international sim card line as before or shall it get me back to Verizon original firmware that is locked only to their lines ??

an update :
I have installed the firmware N920VVRS3BPI1 and it was amazing and working very well .... although it started with Verzion logo at beginning where i had a nightmare ha ha ha ... but after start every thing was ok and the sim card was accepted from Vodafone.

Just so you know you're using the wrong firmware on that phone because it's a N920F not a N920V that phone has an unlocked bootloader and can be rooted with chainfires root and it can pretty much accept whatever firmware because of the unlocked bootloader.

But does this mean that I can install firmware from N920C for example ??
And I can upgrade to Android 7 ?
And still my Sim card from Vodafone can be working without being locked ????

nope. This is a verizon phone. Just look at the baseband or bootloader. I have the same phone and it can be flashed by verizon firmware only..

Bootloader is locked. And there is not such model of note 5 like 920f. I don't know how sellers rename n920v to n920f... My phone now on official nougat QB9 and works flawlessly.

There is a F model it's the international one.
SM-N920F
And it says Verizon now because he flashed the firmware from my android file host account.
Personally I don't think the phones real because that F version usually means that it's a knock off from Thailand.

In Europe galaxy note 5 is N920C. F version is a Verizon version, just аltered by unknown way. N920F version never existed only as a disguised N920V. Just google it and you will see. There is no official firmware for "N920F".

I know but as I said the F version is usually a knock off from Thailand. Personally I don't even think it's real because if the bootloader is locked then how did they get it to say F? The only way to do that is to open the phone and change the chip inside because there's no way a real Verizon Note 5 would be able to do that.

So, you think these phones N920F are not good and I should sell it??, should I look for a new genuine one ?

You should download something called phone info for Samsung so you can make sure the phone is real and not a knock off.. It should have the same exact specs a real one has and if it doesn't it's probably a fake one.

the phone info app is showing a real phone data ...... but when I enter the digits #*0*# it doesn't bring the test screen and the code *#06# doesn't show the IMEI .... is this normal for the Verizon phones ????

I may give this a go. Since receiving a replacement phone fr my original overheating one and getting Nougat update, this phone has been a pain...a real pain. Making phone calls activates the external speaker. I have to tap the speaker icon 3 times to get the ear piece speaker going then when call is answered it kicks back to the external speaker. Very fun in restaurants. Using Bluetooth radio while driving....forget it. Gmail will not download automatically. I'm about to go back to my Note 2.

Verify whether your IMEI is still intact.
Go to:
system settings>about phone>status
or
system settings>about>status>information
or
system settings>about>information
Or whatever similar settings that you have, then check to see if your IMEI number is shown.
I DO NOT PROVIDE HELP IN PM, KEEP IT IN THE THREADS WHERE EVERYONE CAN SHARE

Thanks for your replies. Yes my IMEI is there but its not the same as it is on the back of the phone. However, the first time i flashed the stock ROM it was all the same but i still had this problem of Network not registered.

Are you sure that you flashed the correct firmware for your specific model number?
Have you tried another SIM? If you had the SIM in when you flashed it, it might have damaged the SIM somehow. That might not be your issue but it's worth checking.
Maybe you have conflicting data from before you flashed it, in this case you can try bioting to recovery then factory reset and wipe cache then reboot.
I DO NOT PROVIDE HELP IN PM, KEEP IT IN THE THREADS WHERE EVERYONE CAN SHARE

Yes i used the exact firmware for my model as well for my country. I think i have done what you proposing already. And for trying a different SIM i did try it too. I am really helpless right now

Samsung Galaxy S7 G930F with G930V Bootloader??

I recently bought S7 SM-G930F, but when I went into it's phone info and recovery, I saw that it has a Verizon bootloader. All the rest is of 930f. even the phone says 930f everywhere. I am not sure what this is. I am also facing some signal dropping issues, especially when I switch on to data network. I did the refurbishment check and it came out clean and original.
Can someone please guide me how to fix this? Perhaps a way to change the bootloader to that of 930F without screwing up the phone?
Please find the pics attached for reference.
Thanks in advance for the help.

you phone is a verizon see the snapdragon chipset and the baseband version
either you have flashed a phone with G930F kernel and rom
or whoever sold this to you tried to scam you
dont flash the F bootloader
Your phone is the verizon version which are much cheaper in comparison to the unlocked exynos variants
Flash verizon rom to get back proper caLL functions

Thanks for the response. I think I got scammed then. Two things though:
1) It somehow seemed to work the 1800 band for 4g, which is supported by 930F and not 930V I believe.
2) secondly, even the back of my phone says 930F .. like everything about it says 930F .. like is even the body changed??

And yes this firmware comes with all the verizon bad stuffs but good thing is that most of them can be disabled.I wouldnt care if i wanted to use Nought on my phone.
Still network signal is poor though.

so I successfully managed to flash the Verizon rom. Now my question is, can we altogether remove Verizon and have some debloated or 930f bootloader/rom instead? I saw one video where he converts 930v to 930f but he gave no links to the files he used.

My SM-G955FD cannot connect to any network.

Hello guys!
I have a SM-G955FD. Bought it two months ago and was working perfectly fine till 2 days ago when all of sudden it cannot connect or register on a network. I had 2 sims in it and neither could connect to any network. Instead, it displays this on the status bar instead of the usual bars.
The sim cards work perfectly fine with other phones. The device detects both sim cards.
I have to checked to see if it's an imei error but it is present and it is not blacklisted either.
I factory reset it and it didn't fix it. I reflashed the firmware and it didn't work either.
Also, I cannot dial *#*#4636#*#* either. It says mobile network is unavailable.
Any suggestions?

Weird, did you get this working?
Can you get to the diagnostic menu?

Unknown imei status.
Hello,
This happened to me yesterday and yes I freaked out. It turns out in my case even after flashing other roms I was still having the same problem where sims were not being detected and imei was unknown status. My fix was reflashing baseband. I used latest baseband from the renovate ice website. Hope this may work for you.

Please visit Renovate Ice website, go to firmware and choose the 1st OPTION 'CRI5', download and flash via twrp.
Good luck.
