Hello everyone, I'm considering T-Mobile's LG G2 as my next device over the Nexus 5, but I've heard the latest update locks down the phone preventing the installation of custom ROMs. Is this true or am I misunderstanding something? Basically, If I were to purchase T-Mobile's G2 preinstalled with latest updates would I be unable to install ROMs like CM11 or AOSP at this point? I apologize if this has been answered before, but I haven't been able to find a clear answer and I am anxious to get my next handset.

Yes and no. When you get your G2, it will have Jelly Bean on and not KitKat. So with that, you can root/install recovery and flash CM11 or any other ROM you wish to. But if you choose to update your phone to TMO's official KitKat, there's no recovery yet for that at this point. But you can always downgrade back to Jelly Bean, I've done it numerous times.
Good luck!
Actually there is no way to install recovery on Kitkat. Only way is to have the phone running JB to have root and recovery but there is a way to have recovery on kitkat but for you to have that you have to have jb on your phone first. It have something to do with JB bootloader on kitkat. If you buy your phone and have kitkat. downgrade to jb root flash a recovery. and now most kitkat roms have these patches so you can keep recovery while on kk

When are we going to get kitkat?
Its kinda weird since US CARRIERS are the first one to receive rather than the international version
So yea when are going to get kitkat?
If i flashed kitkat rom of T-mobile or at&t will there be a problem on my phone?
Hoping for some reply
I'm curious about firmwares, basebands, etc.
Would it be wise to flash a stock based ROM (once 4.4 stock is rooted and released, of course) just to get those, and then go back to cm11?
srf, Vodafone is here, rest probably end of march
Why wait?
You don't need to wait, the kdz file is already released.

Hi
I am going to root my G2 for the first time. its currently on stock jellybean.
I would like to know if I should root now on jelly bean and install a custom rom or upgrade to stock kitkat first and then root?
if I am going to a kitkat custom rom would it make more sense to upgrade to stock kit kat first or is it easier to root from jellybean?
What are the advantages/disadvantages of either?
Hi
Can anyone advise on the above? I know I should be reading all the forums which I will but was just after a quick general answer so I know where to start from. I'm not new to rooting and flashing roms but I am new to the G2.
Thanks
I would recommend updating to Kit Kat first then rooting using IOroot25. That way you will have the latest radio/modem stuff to use KK Roms
Depends on the ROM. If the dev says you have to have Kitkat modem or other stuff from Kitkat, then update and root with ioroot25. If not, it will be a waste of time, so:
Download anything you need from the new ROM and put all in your phone storage (so that if you accidentally brick you still have files to flash in your SD), root, install recovery (I suggest TWRP) and from there flash your ROM!
Hi everyone. My phone is rooted and has Safestrap Recovery. I've been anticipating the Android L update for some time and have been used the better part of my weekend trying to figure out how to get that experience. However I'm near my wits end and thought I might as well just ask the experts.
Has anyone tried or know of any way to try out the new update? I've tried a Cyanogenmod 12 rom with the Safestrap Recovery on a new partition or "slot" with no luck. I'd prefer some method that'll let me flash a non-stock rom so I can have the ability to tether (I'm on a T-Mobile sim card with an unlocked phone).
Any advice would be greatly appreciated.
I have also tried a Lollipop ROM, specifically the GPE one, with no luck. We unfortunately cannot use Cyanogenmod, due to the locked bootloader which prevents using custom kernels (SafeStrap is like a workaround, with some limitations). It's only a matter of time before the official Lollipop update rolls around. By then, there'll hopefully be a Safestrap-adapted GPE 5.0 Lollipop ROM.
hey i got an LG G2, D801 model, with stock android 4.2.2. now i would like to perhaps flash stock roms, or costume ones, but i have no idea how to start and if there is a software to flash stocks and such and what do i need to install for costume roms. thanks

Dude, you have to read some basic things to understand, but to give you a direction:
Here's a generell list of guides and fixes. It has a "root"- and a "recovery"- section. Both are absolutely necessary. Go here first.
Here's a list of custom roms. There are stock-roms, stock-based-roms and completely custom-roms. I prefer stock-based-roms because the devs added some extra features and you have full driver support.
I hope this helps a little bit.

i have read some of there before, but i'm yet to understand it, because my previous phone was nexus 4, installing roms and such was fairly easy, and with this LG G2, there are complicated things even as flashing roms, not all models the same and such, and im afraid to brick my phone because of that, i also have a D801 model - D80110C and i have heared that there are different version of things and such.
anyway, what will be the best way to flash stock lollipop / stock based roms and later flash back to 4.2.2 if something goes wrong? thanks
I just did this, in my experience the best way is
1) updating to stock lollipop
2) rooting via oneclickroot
3) flashing twrp via AutoRec (correct version)
4) flashing twrp 3.x blastagator via old twrp
5) flashing desired rom
There is one caveat though, the root process will install the correct (old) SuperSU that works with AutoRec, but google play may update it beforehand so that AutoRec cannot work. My fix was to install AutoRec before the root and then go into airplane mode and do it all in one go. Also, you should always check if you got the correct carrier version of your software.
Going back to kitkat? This should not be necessary imo, but if you mess something up you can always flash the stock .kdz files (lp or kitkat) via download mode and lg flash tool 2014. This phone is almost unbrickable.
Hope this helps and after years of G2 roms I can finally give something back.

do you have a D801 model? i cannot update to lollipop through normal fota or lg pc suite, it doesnt see anymore updates
i have software version of D80110c, what are the last letters means in it? C/G/ and such,
and also how should i update to stock lollipop rom without bricking my phone? it seems that there is alot of room to ****up. thanks =]
I have d802 and could always update it to LP via LG software update in the phone settings.
10/20/30 is android version, 30 being lollipop. 30a/b/c/d is revision or carrier version I think.
I am not sure about D801, but if I was you, I would try to update to LP via official LG update, otherwise try to root+recovery with your existing kitkat (search the forums) or flash LP kdz from download mode (LG flash tool). Always make sure it works for d801 and your software version.
Then I would install a fast custom rom cause stock LP is rather slow.

i tried to update through lg, but it showed me that i am "UP TO DATE" might be because i bought it from someone who bought it in the US in cincenti bell ( and i dont live in the US, or close to it), the phone have a cincinetti bell rom, so i guess that why i cant update it through the phone like that. and i have a jelly bean 4.2.2 , not even kitkat. it is possible to flash a lollipop kdz just like that even if i have stock never tuched 4.2.2 ? thanks alot
Hello
My LG V10 came across the famous bootloop issue, and I shipped it to LG. In the meantime, I am using an old S4 that was saved for emergencies like this one. It is running 4.4.4, I337UCUFNJ4, and I rooted it with Kingoroot.
I understand that it should OTA to 5.1 in pronably a day or 2 if I check for a software update; it sat turned off since 2014, so it did not receive anything.
1. Do I OTA and reroot?
2. Can I manually jump to 5.1?
Ultimately, I would like to install TWRP and the Blissrom or some other ROM, but I don't want to take an OTA that may screw me up for later. I read that there's a loki thing that will prevent future installations of recovery or something like that. I realize that I will be using a short time (2-3 weeks), but I would like to leave it rooted and with a good ROM.
Thank you
The bootloader is locked so that means TWRP cannot be flashed to the phone and the phone will only run custom ROMs based off a stock Samsung ROM.
OTA updates will not work if the phone is rooted.

I'm confused or perhaps you are misinformed. I have seen a lot of ROMs for this device including Blissrom and many others. All od them get flashed through twrp or Safeway or aome name like that.
You mean safestrap?
Maybe you are thinking of the non-AT&T models of the s4 that work with custom ROMs such as Lineage and Validus. Only the AT&T version of the s4 has a locked bootloader, starting with Android 4.3 and up.
There has never been an sgh-i337 s4 with a locked bootloader than can run TWRP. Same goes for the AT&T sm-n900a note 3 with a locked bootloader.

But there's a forum dedicated to AT&T development full of roms here on xda.
Yes, there is a full section but you need to look at the ROM requirements. Some of these ROMs were developed before AT&T pushed out an OTA update that locked the bootloader. Other ROMs are made for the non-AT&T s4 such as the sgh-i337m and gt-i9505.
You will not see any ROM that is not based off a stock Samsung ROM that can be installed onto an AT&T s4 that has a locked bootloader. Also, you will not see any version of TWRP/CWM/Philz that can be installed onto an AT&T s4 that has a locked bootloader. Same goes for the AT&T sm-n900a.
I understand your skepticism and appreciate your posts as we are all here to learn from each other.

Thanks for the clarification. So how do I know if my bootloader is locked? If I took that ota update that messed things up?
The bootloader becomes locked when the phone is updated to Android 4.3 or newer. I think it needs to be on the MDL bootloader to be unlocked. Anything beginning with an "N" or "O" means that the bootloader is locked.
Thanks audit. And I assume that there's no way to go backwards to a pre-4.3 rom and unlock that bootloader.
So. I'm on 4.44 rooted. Do i remove root and take any ota and reroot? I guess that I'll settle for going as high as possible with the stock rom but rooted with the ability to disable some of the bloatware.
How can I proceed?
In those links that you mentioned, it states that we can flash debloated TouchWiz roms that might be better than stock. Is that right? So can I do that?
You will need to install safestrap to flash a custom ROM. The debloated ROMs must be based off a ROM that is designed for the AT&T s4.
I recommend reading through this thread: https://forum.xda-developers.com/showthread.php?t=2616221
Audit... I odined back to nb1, rooted, and used flashify to get to rooted stock oc3.
How can I get to ok3? And should I leave ota services frozen so as to not ruin and loose root?
OTA will not work with a rooted phone.
Maybe this will help: https://forum.xda-developers.com/showpost.php?p=56453108&postcount=2
I don't have an sgh-i337 so I can't tell you how to get back to a completely stock ROM to get OTA updates. I have the sgh-i337m which is the Canadian version of the s4 without a locked bootloader.
I wrote a guide and FAQ revolving around the MDL bootloader here (if anyone cares to read it):
