How to check for locked bootloader? - G3 Q&A, Help & Troubleshooting

I have a G3 model d850pr from Claro PR. I want to check or if any one knows if it comes with locked bootloader or not.

same boat!
Aparently is factory unlock (carrier) theres one on ebay and they says its an international version... I have the original kdz from claro if you need it. i flash it and works flawless.

So the bootloader is unlocked or it is factory sim unlocked? Didnt understand right.

sim unlocked.

Oh ok, do you know if bootloader is unlocked?

don't know.

Its locked, only the tmo version isnt.
Sucks doesnt it.

Well says there 850 not 850pr dont know if they are the same. I say this because our g2 used to be d801 same as tmo version but in reality it was a d803 masked as a d801.

are you trying to flash WP 7.8 on that AT&T phone? if yes, the answer is you can't do that. Variant for RM-808 is not out yet. If you are trying to flash an older update, the answer might be you have an locked bootloader.
edit: obsl = operating system bootloader, so you may likely had an locked bootloader.

OOO, thanks!, and i tried to flash 7.5 version of MEXICO COUNTRY VARIANT because it is debranded and have TETHERING! U_U
did you use "recovery" in 'nokia product support tool for Store 5.0'? I used this to put the mexican variant onto my rm-808 and i have been really happy. I have a rogers version though, don't know what different in the att one

Isn't there a variant you coud flash to from the AT&T variant and then flashing it to the Mexican or Rogers variant?

If you have an unlocked att lumia 900 does that mean your bootloader is also unlocked or is it independent? I have the telcel rom downloaded and ready to flash just wanted to ask as i need my tethering and mms!

If you mean unlocked, as you entered in a 7 or 8 digit (I forget which) number, then no. Your bootloader is still locked, and that'll do nothing. What I'm saying is, you're trying to put a square peg in a round hole.

[Q] Unlocked At&t

So I'm looking to purchase an LG G3, however I wanted a unlocked model without carrier bloatware. I'd like to be able to use it with AT&T LTE. IWhat's my best option?

1) you buy the at&t one, root and delete the bloatware
2) you buy the international one
Unlocked is about the state of the bootloader and I thing you ment something else, if you need a unlocked bootloader try the T-mobile version.

[Q] Which LG G# comes with unlocked bootloader?

I am an AT&T subscriber and in the market for an LG G3. The AT&T version comes with a locked bootloader which means I will probably never be able to install a custom recovery and flash CyanogenMod on it which is a must for me. I realize that other versions will not work with AT&T LTE and I am completely fine with just HSDPA+ - which versions of the phone support AT&T HSDPA+ and come with unlocked bootloader?

Thank you. Does it come network unlocked? I.e. can I put my AT&T sim in and use it?

No, but I've heard of getting unlock codes for as little as $6 on Ebay.
Plus Tmo is rumored to start a new thing soon where they put an unlock app either on the phone itself or on the Play Store and you can unlock it right there.
You'd want to get the Tmo version, though, because it's fully compatable with AT&T's LTE bands.

How many H815 versions there are and how to identify them?

I though that H815 was the european open version (able to unlock bootloader and such) and that the other versions had other names, but I've seen people about talking about H815 versions with the same name and with or without LTE-A, or even specific H815 versions for Asia, France or even non-carrier USA, and on all of them the bootloader is locked as ****.
Is this true? in this case, if you were buying this phone online, how to determine you're buying the european open version? what's the model name exactly for that?
Thanks!
I got mine from handtec.com. I made sure before purchasing that it was the H815 EU. That is what you are looking for. And as a note, I unlocked my boot loader 3 days ago so I know what they sell is the true EU version.

I got my H815EU from handtec as well. Unlocked the bootloader the same day.
Only way I know of is to check settings under software version. For example mine shows V10C-TWN-XX.

I'm also thinking the same thing here. ?
I have managed to root. But I need custom recovery just in case I need to back up etc
to see whether your model is unlockable - please see my post entitled [UNLOCK] list of LG G4 models that you can unlock

Difference between lg h811 and h815t?

So I opened my box today and realized the manual mentioned lg g4 h815t.... I have a h811
Looked up on website both are T-Mobile. What's the difference?
What phone do I really have?
Could I potentionally flash a h815 ROM?

The H815T is Not T-Mobile. The H815T are sold in Turkey and Hong Kong. It's mostly the same as the H815 variant.
If you flash an H815 firmware on your device if it's a H811 you'll permanently brick your device.

LG website states 815T is a T-Mobile phone.
It is possible the manual just has that model number listed and shipped with my 811 device.
How do I really check what version I have?
And why would they state 815T is a T-Mobile phone on their website?

I see no where on LGs website on the H815T page stating it's T-Mobile. If it does it's a glitch. It's 100% not a T-Mobile USA device.
Manuals may not matter as a G4 is a G4 operation wise.
What do you mean check which version you have? If it's a H811 then it's a T-Mobile device. T-Mobile only has 1 model for the G4.
Where did you buy your phone? If used/referb/second hand that might explain the manual mismatch.

Bought it through Rogers. Apparently rogers sells or sold h812
Box imei and serial number match to phone.
Must be manual...manual is a manual.
But why would Rogers be selling a T-Mobile phone.....when they have their own brand?
Anyway to check other than software?

Now that is what's odd. So you bought it through a actual Rogers store? And not a reseller that just happens to sell rogers stuff?
Rogers themselves I doubt would sell a T-Mobile device.

It was actual Rogers store. Not a reseller
Bought it unlocked. Sales rep said he could give me a deal on it so I took it
Glad I didn't get a 812 to be honest, read there are no custom ROMs?

It’s not that it’s not been tried. It cannot be done. If it is you’ll 1. Result in a brick or 2. It won’t work and hope that you’ll be able to flash it back.
The modems in those phones are completely different. Along with the T-Mobile model having antirollback which makes it impossible

Ok well I have the H812 with antirollback value 0. once steadfasterx is fully complete his unofficial bootloader unlock, my plan is to unlock bootloader, install TWRP, then until custom roms for this variant comes out, I plan on flashing other carrier firmwares.... and it seems H815 has better updates, so probably going to flash that one...
Also, can you kindly tell me what you mean by "modem" in the phone? is it the thing that deals with frequency bands?
If it softbricks, I can always re-flash my stock firmware right? What are the chances of a hardbrick?

H812 won’t be as locked down as the H811 is. But flashing wrong model firmware is a no no. Flashing custom roms built on another firmware may not work correctly but won’t be as harmful as flashing stock firmware which will 99% won’t work and or will cause a hard brick.

Not saying you can, but that would be possible before flashing a stock kdz or tot.
Sorry no clue on Roms. Only keep up with stock and flashing to stock.
