Is AT&T G2's bootloader unlocked by default? - G2 Q&A, Help & Troubleshooting

I see all these threads about flashing recovery and rooting on all carriers, so I just want to be sure, is it unlocked by default? If not, is there a way to unlock it?

no it is not and no you can't unlock it. You can use loki to flash a recovery on it and then flash roms.

Loki is basically a bypass that allows you to have a custom recovery, right? Or is it just like a bootstrap/safestrap that requires you to have the stock ROM/kernel still installed?
And does Loki do a factory reset as if you had unlocked your bootloader?

when I flashed loki and recovery and root I did not have a factory reset so everything was still there. Also it allows you to flash roms you don't have to stay on stock

Coming from a Nexus, the procedure is a little different.
What you do is hook it up to the PC and run a script to gain ROOT. Then you download FreeGee and flash a Custom recovery. Pretty straight up. Doesn't require factory resets at all.
And I DO highly recommend using stock for about a week before you flash AOSP roms. The Stock rom is very nice, feature rich, and polished.

here is a link to an explanation of loki given by the creator. it was originally made when the galaxy s4 came out to get past samsungs security called knox but has evolved to work on other devices like lg. it doesnt support most manufacturers, just the ones dan wrote it to support.

I just want to make sure phones I'm looking at are able to be messed with, so I'm not stuck with something stuffed to the brim with bloat forever. I usually stick with stock for a while before switching to custom ROMs.
One last question (I may be lying about that), does the G2 handle 4-6ft drops well? I read one article that said it's about on par with iPhones there.

[Q] Google Edition ROM

I would like to install Google Edition stock rom on my S4 i9505, it is locked to O2-UK, would it be possible to do so without being factory unlocked.
Thanks
No
First of all, you cannot simply install a GE ROM on a regular i9505, because the bootloader and the partitions are different. Also, ODIN will always recognize your phone as an i9505, so you cannot install GE ROMs this way.
What you can do is flash CWM and use a Custom ROM which is based on the GE ROM. But this is not exactly the same as a stock GE ROM. It comes close, though, and usually is 'better' anyways due to 3way reboot, root etc.
locked to O2-UK

What does this mean? Is your bootloader locked? In this case you can only install ROMs via ODIN AFAIK, unless someone already has hacked the bootloader so that you can install CWM.
Edit: If your bootloader is locked you can only install stock ROMs of course, or some stock-based ROMs which don't touch the bootloader or contain an official bootloader update.

This is what I meant sorry. Flash a new ROM based on the GE. I have never flashed before so wouldn't know where to start.
I mean carrier locked to O2-UK, it is completely stock so I am guessing the bootloader is still locked.

Start reading the forums before you start flashing. These are basic questions. Read, learn and prevent your phone from becoming a paperweight.
I can tell you all the steps you need to take, but then you still don't know what you are doing.

[Q] CM11 Problem.. Help Needed

Hi all,
I am interested in the CM11 ROM. Last night I spent 6hrs trying and failed, epically.
Here is what I did already:
1. Downgraded from 4.4.2 back to factory
2. Successfully rooted
3. Installed ROM Manager
4. Successfully downloaded CM11 and latest GApps
Then when I tried to boot into recovery it kept going to a screen with a little android guy lying on his back with a red triangle!!! I tried six times.
I got frustrated and just updated back to 4.4.2 and have been dealing with it. I am still rooted and have been able to remove my bloatware and other things you need root access for.
Any thoughts or help as to how I can install the CM11 rom?? I am happy running NovaLauncher and using DynamicNotifications to approximate it but really want to try out CM11.
Cheers and thanks!
Lucky there is no way to root on 4.4.2 yet or atleast no Recovery's yet it could be worse you're atleast rooted and it didn't brick your phone

Did you actually try flashing a recovery first? Just installing ROM manager won't install the custom recovery needed to flash ROMs. You have to do that step as well.

LG blocked the Loki exploit with 4.4.2 so you can't flash recoveries currently. You'd have to flash back to 4.2.2 to do that. Which if you want custom ROMs now its going to have to be done sooner or later. Which carrier and model number do you have? If you have an international D802 the above post by @zekurosu will work for you, otherwise don't use that one. You're gonna have to find the method for your model number.
My first guess was that you missed the flashing the custom recovery step, which people above me have already helped ya out on. For being new to Android you did fairly well, you just missed that one step.
Good luck!

I have an ATT D800 running 4.4.2. I can't decide whether its worth it to flash back to 4.2.2 to try again. Pretty happy with NovaLauncher + widgetlocke and fairly closely approximates what I am looking for.
For what its worth, I was in 4.2.2 when I tried the first time and failed. I think mackster is right, I didn't flash the custom recovery. I basically flashed back to 4.2.2->rooted->tried to boot into recovery (OVER and OVER) then gave up and upgraded back to 4.4.2.
Thanks for all the help. At least I now have a rooted phone and have been able to do some cool stuff with that. My goal is to get nexus 5 software in an LG G2 body (battery, camera, etc)
@android_nashville There's a way to have the best of both worlds. You can flash back to 4.2.2 (10d preferably) root, flash a custom recovery with Flashify or FreeGee. Both available on the play store. Then actually update to 4.4.2 following this thread http://forum.xda-developers.com/showthread.php?t=2483043. Eventually, if you want to flash custom ROMs you're going to have flash back to 4.2.2 and do this process regardless. The 4.4 aboot image (bootloader) can't be bypassed with Loki. Its been blocked. But some brilliant devs basically found out they can make a hybrid setup, with the 4.2.2 aboot, and everything else 4.4.2. This way you can have the ability to flash custom recovery, kernels and ROMs.

[Q] How can I upgrade my stock rooted rom

I have searched the forum and have been overwhelmed with threads that I can't seem to make fit my situation so I apologize if I've overlooked something obvious.
I have an AT&T S4 That came running UCUAMDL. I rooted when I first got it and have not done anything sense. I would like to update the stock rom but I don't want to lose root. At this time I'm not interested in custom roms although I've done it before on my S2. What would be the best option to achieve this aim.
Thank you in advance and again sorry if I missed this somewhere.

Your best option would to be to flash a 4.4.2 custom rom. There is no root for the latest, nb1, firmware.

Thanks for the quick response. Makes since. So as long as I flash a custom rom I don't have to worry about bootlock or anything, right? What's the closest rom to stock as far as stability & compatibility?

Then I would try kangakat which I believe is loki'd. Make a backup in twrp of your current rom before you do anything. If you don't have titanium backup, get it and backup your apps. And make sure you have Google's backup and restore checked, settings, backup& restore.

Yes I have titanium backup and I will be sure to back up everything.
I was not familiar with loki so I did a little reading. Correct me if I'm wrong here but loki is something the rom developer uses to make it so my rom installation will go around the boot loader. I don't need to install anything related to loki I just need to make sure any rom that I chose is "loki'd". Correct? Therefore if my understanding is correct, once i've taken backup precautions, I would copy the loki'd rom to my sd card and flash via TWRP?
Again, I want to thank you for your help.

Loki is something the ROM developer can use. You either need to make sure the ROM is loki'd, or if you ever want to try something like an I9505 ROM, flash the loki-doki zip file after flashing the ROM (i'm not sure where the link is). Most ROMs in our dev section will have loki included, but i'd keep the loki-doki zip on your SD card just in case.

[Q] AT&T I337 MDL - Newest Firmware

Been trying to read and figure out as much as I can, but I'm lost. I rooted my phone right when I got it a few months after release. I have the MDL firmware and I'm running stock that I've modified to my liking. I rooted using motochopper, I have TB and SU and I have TWRP installed. I'm ready to take the jump and try to get an updated firmware, but don't know where to look. It seems a lot of the info in now for the newer firmwares.
I would like to run either Google edition or a modified TouchWiz I think. I like keeping things pretty clean and fast. I am currently running Aviate on top of TouchWiz and I like the clean organized feel of it, although a bit laggy.
Please help me XDA, sorry I know this is a newb post. I've been blocking the OTAs for over a year and I'm ready to move on.
First I would suggest NOT to use any STOCK firmware to update to 4.4.2
There are some newer Google Edition Roms I believe in the ATT original ANDROID SECTION. You can use them since you have twrp recovery. Those with newer firmware cannot use the latest google edition Roms unless they are made for safestrap.
Or if you want a modified stock Touchwiz with all the extra benefits you can flash directly to ShoStock-i 8.1 which is 4.4.2 based.
Keeping you MDL bootloader and the Loki bootloader bypass you have now let's you flash ANYTHING you want, including kernels.
If you update firmwares the bootloader becomes MORE LOCKED DOWN and you cannot flash any Roms that need a modified kernel like aosp based Roms, or any kernel other than stock.
Thank you ill check those roms out. I am aware that I DO NOT want to update my firmware, that's part of the reason I asked for advice, to see which roms work well with MDL. Most of what I found was all for newer FW versions.

Sorry I haven't tried OUDHS so I cannot comment. But TWRP still works perfectly. For ShoStock you would NOT need to flash Loki-Doki patch or anything. The kernel in ShoStock-i is already Loki patched. If you plan on trying other Roms it is always best to keep the Loki-Doki flashable zip on your sdcard and flash it after flashing a ROM. Just extra insurance that won't hurt anything if the ROM is already lokified.

Sprint Galaxy S4 Rooting

I've spent hours searching and I know this is an old phone. Is ther anyway to root the Lollipop and download Jelly Bean (custom or stock) to it? I'm not worried about Warranties. I'm not exactly a newb and I don't like Lollipop at all. I don't mind KitKat, but what I hate is the front facing camera can't be flipped. Dumbest thing ever.

You said you're not a newb. So what exactly was the procedure used to to install those ROMs?
Well, you should be using CF-Autoroot, as it's the recommended method to root these devices. That said, unless you have a frankenphone, only AT&T and Verizon models have locked bootloaders. Enter download mode and verify your device's model number please?

Update: I went the CF-AutoRoot route and then tried to use Odin to flash stock mk2 rom. Now that I remember it kept failing everytime and then it would corrupt the current rom. I also tried using TWRP and couldn't get it to work properly.
That's a Sprint device, so your bootloader is unlocked.
Here's something you should note: If you want to flash a ROM, of any kind, you don't necessarily have to be rooted.
Stock ROMs require Odin and custom ROMs require a custom recovery. None of them require root.
Your flash to an older version fails most probably due to the fact that you're trying to downgrade the bootloader (Any stock ROM flash also modifies the bootloader and modem partitions).
But your windows, cable, USB port and windows can also be at fault here.

For some reason I kept reading that it was locked or thinking it was locked because of not being able to downgrade.
So that's what I thought and I guess that's what I was trying to get at in my first post. Trying to go from Lollipop 5 to Jelly Bean 4.3 or so. Is it possible to do that whether it's custom or not?
I just hate the Lollipop and the KitKat. My Galaxy S2 had the JB and Power Button took a crap. So I ended up getting a S3 and now been sitting on an S4.
I know it's not the cable or at least it shouldn't be because it works to flash the stock current rom everytime I corrupt it. The computer is like brand new and running Windows 8.1

Downgrading sometimes succeeds. There are also guides on how to downgrade, though there aren't any special procedures. Maybe the bootloader version of the firmware-to-be-flashed matters.
With custom ROMs it's definitely possible, as they do not change the bootloader.

If you can find some viable download links, then yes, you should be able to flash custom jelly bean ROMs. But you need a custom recovery in order to do that.
The recovery can be flashed with Odin. Or, since you're rooted, you can also flash a recovery by using an app called Flashify.
Odin requires a .tar file and Flashify requires a .img file.
Oh, and you also need the gapps package for the Google Apps. You need a package for that specific android version, so it should be jelly bean gapps.
