Greetings,
I have been looking for a while, but still cannot find an answer. Any help would be great.
I have G3 ATT D850, unlocked and running on TMo, stock 6.01, unrooted.
I would like to install latest lineage ROM.
Trying to find the step by step instructions but cannot so far.
Most apply to rooted phones. This one is hard to root at 6.01 version.
My understanding is all I need is to unlock bootloader to load custom ROM and custom recovery, but I cannot figure out how to do that.
Any ideas?
Thanks much

I have a quick question. I am on a stock rooted 4.1.1 att sgs3. I was curious if i flashed this rom/kernal,[ROM/KERNEL][4.4.2] Quantum 3.54 & QuantumKernel 3/7, would i be able to go back to my stock rooted rom if I wanted to? Thanks in advance.
Looks like you are trying to flash a custom ROM. Don't know much about these particular ROMs you mentioned but you need to your research thoroughly on custom ROMs before flashing. You may know most Custom ROMs don't come with their own bootloaders but still have to rely on a manufacturer's bootloader to run. You should, therefore, avoid any ROM that may update your bootloader because this is the only way that you would not be able to return to your previous stock version. If the ROM simply updates the system without mucking with your bootloader, there is no reason why you may not be able to return to stock.
I had an AT&T SG3 on stock 4.1.1 and I was able to flash KitKat (4.4) based CM11 and return to stock 4.1.1 without any hitches. Finally, whilst you are still on stock 4.1.1 I would suggest you take advantage of all the flexibilities offered by this Android version especially free unlocking before you begin tinkering with firmware.
So as long as I dont update my bootloader, I should be fine on going back to stock rooted 4.1.1? Thanks for the info!!
So how do i know what roms dont mess with the bootloader?
Most ROMS do not include an aboot file. I have flashed CM11, Validus, Slim, and Cyanfox and none of these altered the bootloader.
I suggest that you find a ROM you like, unzip the file, and look at the updater script to determine which bootloaders are required to install the ROM on your phone.
Ok guys, thanks for the tips. I just didn't want to get stuck on a firmware where i could not have root anymore or go back to a stock rooted rom.
Hi,
I bought a locked Samsung S3 (At&t). It is rooted with cyanogenMod 10.2 Android 4.3.1. All i was trying to do is unlock it so i can use it with other carrier. So i bought the unlock codes for 30 bucks but later i found out that the unlock codes only work with Stock rom. I am not an expert at this Root, Custom Rom...stuff, but not idiot either i can follow step by step directions if anyone knows how to make this work. I would like to use the custom rom though, so do i have to recover in stock rom, unlock the phone using the code and than install the custom rom again?
Plz help

Yes, that is what you will need to do. As you can only enter an unlock code on a stock ROM (or one of the numerous custom ROM based on the stock one), you won't be able to make it work on CyanogenMod or any AOSP derivatives. You will have to revert back to stock, then (if you want to try a cutom ROM) install another custom ROM of your choice, be it CM or anything else.
Though if you currently have CM installed in your device, you most certainly already have a custom recovery (TWRP, CWM, PhilZ Touch...), which make it even easier for you to flash ROMs at your will -- the step of installing a custom recovery is already done. So browse the AT&T SIII Android Development forum, choose a stock-based ROM, install it -- pay close attention to the installation instructions in the ROM's thread --, unlock your phone; then repeat those steps to install another ROM if you want to.

Could you please direct me to how to unroot? I am able to go into the recovery mode but not really sure how to go on from there. I appreciate the help.

Before you flash a stock ROM, you would need to check what bootloader your phone is currently on as flashing the wrong one could cause your phone to brick or become unusable. Custom ROMs like the CM you currently have do not have their own bootloaders but rely on manufacturer's bootloader to run. The bootloader, quite simply, is a small application that loads the operating system and all other applications & systems required for the phone to run once it is powered on. Therefore, with a faulty bootloader, your phone can not gather all the resources required to power on successfully. If your phone is running on the 4.3 bootloader which would be the case if it was on 4.3 before the update to a custom ROM, then you would have to return to stock Android 4.3 which is the latest OS available for the AT&T GS3. However, if it has an older bootloader, then you can flash Android 4.1.1 via Odin.
There are different sets of instructions for either system so I would suggest you check your phone's settings and advise the OS parameters you can see there so we can steer you in the correct direction.

Did the phone originally have 4.3? or did it have an older version before you installed CM 10.2. This would determine how you would go about it.
Also is there a custom recovery like clockworkmod installed?

I have installed the latest nightly of cyanogenmod 11 now. Before i have the stock AT&T 4.4.2 rom.
To install the custom rom i have to flash the stock AT&T 4.1.2 rom, after that root that one, install freegee, install CWMR. And after that install the cyanogenmod rom from the recovery mode.}
To make the 4.1.2 rollback i used this http://forum.xda-developers.com/showthread.php?t=2302660
The method above is exactly what you need to do for a good deep sleep on custom kk ROM... If you don't like the custom kk ROM and want to try another one ...do process all over again with new ROM. Good luck

I've been trying, without an ounce of luck, to flash a custom rom. I'd love to update to Kitkat, and I'm currently running a rooted stock ICS. Almost every ROM that I've looked into says to flash with CWM, but I can't seem to find a version that will properly flash onto my phone. Am I doing something wrong here?
In the process of flashing the stock JB for Virgin Mobile. Hopefully once that's complete, I'll be able to get the next step going.
Hi folks. Long time rooter/rom user of phones and tablets. I have some questions for my V500
Since it is rooted, would this be the next step - http://forum.xda-developers.com/showthread.php?t=2641409
(Installing TWRP for a custom recovery)
Since I'm on 4.4.2 with a V50020d base, would I then focus on getting 4.4.2 base roms and flash them via that TWRP I installed?
This does seem like a really fun and snappy device. From what I can tell, it has an IR Blaster right? Are there any roms that don't work with the blaster (I see this sometimes in the Galaxy Tab roms for devices that have the IR blaster)
Once you root, the next step is installing TWRP so you can install roms.
I also have the V50020d UK version.
Stumproot which is available here worked fine for me, easiest root i have ever done. Just install apk and your done.
Installing and getting custom recovery to successfully flash a ROM is another story. I have managed to get TWRP flashed to the device and boots correctly. However it fails when i try to flash CM11 or any other ROM. After reading around I think I may have to downgrade the stock 4.4.2 to 4.2.2 in order to get TWRP to flash. I am not struggling to find the correct stock 4.2.2 kdz firmware for the v50020d device.
It's been a bit of a head scratcher! Let me know how you get on with yours.
Cracked it today. I've written a guide for all UK users who are stuck with V50020d, compiling all the info. http://forum.xda-developers.com/lg-g-pad-83/help/v50020d-uk-root-twrp-flash-stock-4-4-2-t2938914
Hope it helps

I did mine with towelroot. I'll be looking to flash a custom recovery soon. I wanted to pop in here first to double check before going ahead with a recovery and a rom.
I new to LG and have 2 of these for my boys.
I have a us and uk one, i assume these will need different ways of rooting and flashing twrp etc?
I rooted one with Kingoroot no issues, but damn, getting cwm to install is a mare.
Both mine are on 4.4.2.
Looked at so many tuts, they all change due to time and i had to give up as was draining me.
Any tips on how to get cwm installed fella.
Best wishes
