now that the boot loader is unlocked, it would be safe to flash a rom from any other US variant correct? or do we still have to wait for verizon only roms?
also, how would one root before or after the unlock?
If the underlying hardware isn't different, from what I've read, it should be fine.
Folks are already flashing sprint and att kernels to the unlocked vzw gs3, so yea it should work! Although I prefer to stick with software developed specifically for this device.

hi.
ive been hearing about unlocked bootloaders lately. Don't know anything about it.
So... what is it exactly? And is out G2x have an open bootloader?
Thanks
When the boot-loader is locked you you have limitations to what you can flash. You can't overclock to my understanding, and you can't have ROM's like CM7 flashed onto it.
G2x doesn't have a locked bootloader. But phones that do are usually Verizon's Droid line. HTC used to lock them down, but have recently changed their minds.
LG's corporate policy is to NEVER lock the bootloader. If you buy an LG phone the bootloader is unlocked, period. If you want to flash anything other than an official update you must have an unlocked bootloader. Phones with locked bootloaders don't allow you to flash custom recovery and roms. There are ways around a locked bootloader to flash custom roms, but that discussion is beyond the scope of this thread. If you want to guarantee an unlocked bootloader stick with LG phones.
I recently bought an AT&T S4 I337 and I really hate the locked bootloader (and lack of cyanogenmod goodness).
On my last phone, an LG Nitro HD, the method used to unlock the bootloader was to force-flash it to a different carrier's LG image for a similar model which happened to have an unlocked bootloader.
I wonder if it's been tried on the S4... I think I remember reading that T-mobile didn't lock thier loader and since t-mobile uses the same modem type (IIRC), I wonder if one could use ODIN to flash said image (and use the update bootloader option to slip the unlocked bootloader)?
I'm probably crazy for even asking... but I didn't recall reading that this hadn't been tried.
Not a clue in the world, but I'm crossing my fingers.

Sorry to burst your bubble, but due to physical hardware limitations this will never work. I would go into details but it's fair plastered around the forum as to why this wouldn't work. If it where this simple we'd have unlocked the bootloader ages ago.

This has been mentioned and covered many, many times.
Ah. I personally didn't see it mentioned anywhere when I searched but with the ocean of threads around here, I could understand them being buried.
Well, **** then.
I have a Verizon tablet. I would like to flash a version of the firmware did not come from Verizon, the same firmware that I'd have gotten if I didn't buy it from them and is not tied to any carrier at all. Is this possible without doing anything weird that you'd have to do with a custom ROM like unlock the bootloader? Or can this be accomplished with no complications whatsoever by flashing through Odin?

Firmwares are model number specific plus, Verizon has locked bootloader on every one of their Samsung devices younger than 2 years old and some of the older ones that have been updated to Lollipop or newer have locked bootloader, some are locked as far back as KitKat. If the device you have has a locked bootloader then it's not gonna allow you to flash anything that isn't Verizon firmware.

Got it, thank you.
gretting and salutations,
I recently traded my iphone 6 plus with a busted screen to a store for a galaxy s7, which is still under warrenty so im hella stoked. Anyway, love the phoone. Would like to root and flash something vanilla. or as vanilla as i can get.
I have an att model g930A, unlocked and on t-mobile.
I've been looking in the forums and im not seeing alot of roms for the att model, which i guess is different than the international version.
any insight??
As i said, id like the be as vanilla as i can get.
wifi calling is not required and neither is VOLTE.
-As long as tethering works, im fine.
Yes the US models are using a Qualcom CPU instead of exynos and have a locked bootloader which makes custom ROMs near impossible.
I believe you can flash stock ROMs with Odin, that's about it.

there is an option under developer options for oem unlock and i read that unlocks the bootloader.
i dont mind the phone as it is but id like to debloat or just flash straight android. no bloat.
You can find a thread here https://forum.xda-developers.com/ga...covery-official-twrp-galaxy-s7-t3458579/page3 discussing the unlocking of bootloader.
According to a post in early May it still hasn't been done for US models.
Really thinking about flashing the U firmware but I'm worried about my unlock.
I couldn't go thru att but I did pay for a code, if that matters. Reading on the forum it should be fine if you got it thru att but IDK what my process is classified as.
Need to pick up a few phones to play with. Since they all seem to have their own bootloaders (or do they?), should I go with Verizon, ATT, Sprint phone, or?

Virtually all models of devices from the major US carriers are going to have locked bootloader with no way to unlock them. I suggest getting the devices directly from the manufacturer or buying international non branded devices because the majority of them have unlocked bootloader or bootloader that can at least be unlocked.
If a US phone is "unlocked", does that mean the bootloader is unlocked or just unlocked for carrier use? I also hear phones directly from Samsung are locked also.

When you buy a phone that says it is unlocked, yes, it is referring to the fact that it is SIM/carrier unlocked to be used on other carrier networks.
Unlocking bootloader is a very specific procedure in order to modify the device or add/remove pieces of system level software If you're looking to use custom recovery and custom ROMs, you will definitely need to make certain that it is a model that has the bootloader already unlocked or has a stock firmware version that has a bootloader that can successfully unlocked. Typically, the older the firmware version for a specific device model number is the safest bet, the later, newer updated firmware for that specific device model number tend to have locked bootloaders. And it gets worse as the devices get newer and more improved with security features and roadblocks.
A safe bet is a Non US Google Pxel device, they are all very well supported here. Regardless of the device in question, you don't ever want anything that Verizon has to offer, period. AT&T and Sprint are just as bad.
Droidriven - Thanks for the info, thats what I have been reading, and, what makes me wonder. If I can get unlocked phones with locked bootloaders, and I am not going to mess with he bootloader, is there one "locked" bootloader better than the other?
