Need help on H811 unlocking - G4 Q&A, Help & Troubleshooting

Guys I brought a H811 which is already carrier unlocked and I can use any sim available in our country.It's currently on LP 5.1 and I want to install any custom rom based on MM like genisys and so on may be cm also. So I have a question before trying to get root or flashing anything via TWRP or flashing firmware via KDZ that after each flash will it again be sim locked?
After each flash will it again ask for sim unlock code?
Actually I am pretty noob on this things and didn't used any locked phone like this before.
Thank you in advance...

Network Unlock not working - Do I need stock?

I am running SlimKat 4.4.2 on an i747. Baseband = I747UCDMG2.
I received the Network Unlock code from AT&T. Inserted a T-Mobile sim card, and when I entered the unlock code it was unsuccessful. I have seen comments that Network Unlock will only work from stock, but none of the comments seemed very authoritative.
Do I need to revert to stock in order to unlock the phone? If so, will this method http://forum.xda-developers.com/showthread.php?t=2722660 get me what I need? If there is another way to do this, or something else is wrong, I'd like to know about it before going through this.
Thanks
Yes you have to be on stock and use the stock dialect to do what you want to.

I'm sorry, what is the stock dialect? Will the Odin package in the thread I referenced provide me with what I need?

Stock dialer is what is required.
And no, if you flash 4.3 firmware you will never be able to use the free unlock method. Odin flash 4.1.1 firmware only. Then you can unlock. You'll have to factory reset too btw.
DIALER. Got it!
As I stated in my OP, I received my unlock code from AT&T already. I'm not trying to use the free unlock method. Will the 4.3 firmware work for that?

Yes, just enter another carrier's sim card to get prompt for the unlock code.

The G3 has an exploit called bump! which fools the phone into thinking it is receiving genuine LG images(i think that's how it goes), so there is no need to unlock the bootloader. Our custom ROMs come signed already, so just flash like you normally would.
& FWIW the vs985(verizon) comes carrier unlocked out of the box so any sim should work...you just need to manually set up the APN for data.
Thanks for your reply

You need to root first, but yes, that's the idea

what do you mean by root .
if bootloader in unlocked then just we need to install custom recovery to flash custom rom right ?

First you'll root your phone.
Then, you'll install autorec so you can have a custom recovery.
Then you can flash any rom you like that's compatible with your phone model.

Go with T-Mobile
Their LTE 2nd fastest to Verizon and more development options than the other carriers

Flashing lineage os with locked bootloader

hi just to ask has anyone here manage to flash lineage os on locked bootloader?cos the new firmware has multi window and so tempted to try it.
Personally, I hardbricked the phone even with doing proper guide... Sending it back since still wararnty..
If anyone else have different result perhaps can help?
Right now I'm using LineageOS with locked bootloader. I think if you want to use with locked bootloader, don't flash the firmware provided by nijel8.
thanks for the replies but already unlock bootloader and flash lineage os best rom so far

If you are not the MIUI fan, then Lineage by nijel8 is the best option to go. I am on locked BL, and so far is OK!

Unlock bootloader

Hello. I was able to root my note 4 and looking to flash a rom. I read several threads and they mentioned that the bootloader also need to be unlocked before I can flash a new rom. I'm not sure how to do that. Could someone please guide me there? I used to have a s4 so it was just root then TWRP then flash my favorite ROM. Not familiar with this phone at all
I took the latest update, it is n910pvps4dqh1, Android 6.0.1
Thanks experts

Bootloader locked only in verizon&AT&T N910V/N910A.

Yessss. Good to hear any good rom can you recommend?
Thanks

If you have a carrier locked US model there is nothing you can flash in ODIN to unlock the bootloader, as odin packages dont touch the firmware. Best you can do is hope an exploit gets found or return the phone.

Might I ask how you managed to flash a different firmware version? What method did you use to flash the A546U1 firmware?
I ask because from what I understand, the A546U version does not have the option to unlock the bootloader and in order to flash anything at all (including another stock firmware), you must first unlock the bootloader.

You can flash any stock firmware without unlocking the bootloader as long as it's official firmware

And what is the process for doing this?
Flashing another stock firmware, that is?
My objective is to flash an official European version so I can go into dev settings, unlock bootloader, the proceed to flash a custom ROM.

If you're trying to do this on a US variant then it won't work

Do you know the reason behind this?
Because my understanding is that having a locked bootloader is the only thing preventing me from flashing a ROM on my US version (A546U).
What else is preventing me from flashing a stock official firmware on my A656U using the method you're referring to.

Well that's unfortunate. I wonder how the person who made this thread managed to flash the A546U1 firmware on a phone that was originally A546U.

Odin does allow that for some reason since they're both U.S. firmware
