Ok i recieved my galaxy s3 in the mail today and look up how to root it.I found a very easy way by using towel root with supper something to do some binary configuring so it would be a good root.Any way after my device was rooted i decided to get CWM so i could install a custom rom.I tried odin but when i tried it it failed to flash.So then i went on the play store and got rom manager and installed it through there.I then tried to get into CWM and saw this message "Verizion has detected 3rd party software bring it to a verizion shop" something like that.Anyway idk what to do now.Do i unlock the bootloader now? is the bootloader even the problem? if i unlock the bootloader will my device be okay and will i be able to get into CWM? i really need help its been a while since i rooted the last time i rooted it was a samsung galaxy player 5.0 and i was able to get CWM and root i digress.Thanks in advance.

Your going to be upset but you have a locked bootloader. You cannot have custom recovery or most custom roms. I suggest you return it if these things are important to you and get an at&t or t mobile s3 because neither of them have locked bootloaders

The at&t galaxy s3 bootloader is unlocked. They started locking the bootloader when the s4 came out: http://www.ubergizmo.com/2013/08/att-stops-unlocked-bootloader-support/

Right its an older baseband/update that's unlocked just like the VZW S3 running 4.1.2 was unlock able but newer versions are not unlockable

On the AT&T S3 (i747) once you take the 4.3 update (MJB) the bootloader is restricted in that you can not down grade it, or any subsequent updates. (It is my daily driver phone)
It is not locked in the sense that you are prohibited from rooting, flashing custom recoveries, custom ROMs, etc. Once you upgrade to the NE4 bootloader and modem you must keep the version numbers for the bootloader and modem matched. It is possible to run custom JB roms on the KK bootloader and modem, although you may need to edit the updater script to get the custom recovery to flash the rom. People are running JB, KK, and LP ROMs on firmware from 4.3 upwards. These ROM are TW mods, AOSP, CM, and CM derivatives.

That's pretty much how it was on the VZW S3, after the 4.1.2 update there was no going back

I agree with you about the no going back.
The big difference is that the AT&T S3 can install the custom recovery or ROM of your choice even if you have taken all of the OTA updates. It is not limited to two or three "safe" ROMs.
Anyhow, all of this is off topic of the thread.

Ah no worries there. It is what it is. I'd rather just have an unlocked bootloader and not have to fiddle with specific things. I'm loving my Nexus and wouldn't go back to a Samsung right now if I was paid to do it

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.
This is an unlocked T-Mobile G5, but why have a special ROM for unlocked phone? I wonder if I flash other ROMs, I could lose the unlock. Anyone have any problem rooting and install twrp?
Conclusion after a month long discussion:
G5 with H83020i_un ROM is NOT factory unlock. Upgrading or downgrading will result in SIM lock to T-Mobile, period.
Once locked, it can only be unlocked by T-Mobile customers via T-Mobile unlocked app. Some has to go thru T-Mobile customer service and request SIM unlock by adding IMEI to their database.
I bought 6 (New to New other) unlocked H830 and 2 has the hacked ROM H83020i_un and 4 were completely locked to T-Mobile. Yes, those stupid sellers on ebay just keep sending lock phones as unlocked phone! Good luck getting a unlocked one.
No, you cannot install TWRP or root this version.
I ended up returning mine.
You shouldn't lose the unlock by flashing another ROM.
A ROM isn't just about 'locked or unlocked'. The ROM is the operating system. While it will still be Android no matter what you do, different ROMs are modified differently to provide additional features, or more control over the settings or just a slightly different user interface.
This has NOTHING to do with the phone being unlocked for use on any GSM network.
For example some people want to be able to control the CPU processor speed on the phone more. Some ROM's give you that control built into the settings and use customer kernels that allow the CPU to run faster than it does running stock. Other people just like a more simple UI that you get on base Android ROM's (rather than some of the overlays LG puts on)

I can't confirm this personally, but @autoprime mentioned on IRC that everyone who tried flashing other KDZs over this specific firmware lost the SIM unlock.

I don't know when people will understand that it has nothing to do with sim unlock. I have T-Mobile unlocked sim lg g5 and flashed roms, custom and stock both several times and never had any problem with sim lock stuffs. Just install twrp, root, flash custom rom, there will never hurt anything in your phone.

It seems that this is not a regular unlock. When I open the T-Mobile app, it says the phone is still locked, but it works anyway.

Did you confirm that by trying the phone with a non T Mobile SIM on a different network? Or did you just let the T Mobile unlocker app tell you it's still locked?
The app isn't the most reliable thing in the world. It's known to say it's not unlocked when it is or that it can't be unlocked when it already is. Etc etc...
Unlocking it manually (through codes, ADB, root, etc....) messes with the unlocker app. But the unlock itself should still be valid.

Maybe it is something to the specific phones people are getting from the ebay seller. They are being sold as new yet are not factory sealed and missing the Tmo sim card. People are claiming Android pay doesn't work and the phone isn't rooted. A new out of the box phone shouldn't have that issue. So something isn't necessarily kosher.
Guys, I have the same version (H83020i_un) and it has April security update and T-Mobile has different version #s on their website. I have checked for update, but nothing came up. So I can't get T-Mobile updates?
The software version H83020i_un is apparently not an official ROM released by T Mobile or LG.
There is a lot of speculation on Slickdeals (a website for coupons and stuff where this eBay deal has been discussed quite a bit) that the unlock was done by flashing a modified ROM. If so that would explain why flashing a new ROM loses the unlock.
Additionally people are saying that Android Pay doesn't work on this phone with that software update, presumably because it's not official firmware. I've never used Android Pay so I have no idea if it works or not.
All in all if you have the H83020i_un software and bought the phone 'new' I think you got conned. It's not new and that seems to be unofficial software.
I spent a lot of time, with help from @autoprime, trying to figure out where the unlock is stored. I was able to dump the partitions from 20i_un using the method here. After I downgraded to 20A and flashed TWRP, I flashed back all the 20i_un partitions (besides recovery, cache, and userdata), and it still wasn't unlocked. So I'm baffled as to how the unlock works.

I see. It will be used as a second device, so it is fine. I flashed the phone with stock T-Mobile H83020a, then got few OTA updates. Now my phone has H83020i, but T-Mobile's page(below) shows an "f" version as the latest. So is the H83020i, the latest update or not? Also would be good if anyone with real T-Mobile unit could chime in.

AT&T, it's stuck on the May security patch.
I had an att s6+ before and used it oversea. I never got any ota updates. Only hope is Odin. You may want to att s8 forum to confirm.
Looks like it is my only hope. What exactly is Odin and do I flash a carrier one or a stock one. Then if I do the stock one do I get normal updates.
Possible for anyone to link me to a guide on how to flash this unlocked AT&T s8+ to a factory unlocked one or a Three-UK one? Also by doing this will over the air updates start working.
I think att locked the bootloader so no you can not flash other carriers rom. Sorry.
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?
